Has anyone else on Ship Board been following the unfolding ‘battle of the sciences’ between biologists on both side of the philosophical divide…philosophical atheists Dawkins/Gould et al on one side and philosophical theists Behe/Schroeder et al on the other?

If you have, you will know that Darwin’s theory of natural selection as a means for explaining the origin of life and the origin of new species is coming under increasingly objective scientific criticism.

In addition, Richard Dawkins, in his book, ‘Unweaving the Rainbow’, has crossed the line in the sand between ‘science’ and ‘religion’ and boldly asserts the atheistic philosophy which supports his view of the universe. On the other hand, Michael Behe is undermining Dawkin’s authority on such matters by pointing out the ‘irreducible complexity’ of bio-mechanical systems such as blood clotting and cell mechanics, which could not have developed step-by-step as Darwin predicted.

The arguments are numerous and complex and I do not which us to go into them on this thread (perhaps another thread can cover each side of the battle). What we need to discuss are the implications of the potential result for the life church.

Much of the theology of last century was shaped by the ‘scientific’ Darwinian view of the origin of life. If Darwinism proves false, much of last century’s theology will be confined to the dustbin and a refined theology will emerge.

In light of this, I have this question to put to the Board.

If biologists show that life could not have just appeared by chance, if a theory develops requiring an intelligent agent behind the original of life, what will be the outcome for the church?

How will our theology be effected? How our new theology effect the issues surrounding the church in the late twentieth century? What will be the new issues?

Discuss

Really interesting thoughts. I suspect it would just result in a revival of Smugness in the church!

There would be huge discussions on the nature of Intelligence, and a resurgence of interest in Erich von Daniken (the guy who led me to Christianity with his ridiculous - to me - theories!).

The Rosewell Conspiracy Theory people would enjoy new respect - at least amongst themselves...

And there might be even MORE money poured into Space research at the expense of the sick and hungry here on Earth.

I don't think the whole of Darwinism is going to die. I think it may be modified, like most scientific theories are, as we discover more and more.

Natural selection is about as close to a scientific fact as it's possible to get, so the basic theory of evolution is not under immediate threat. And Darwin himself didn't think of his theories as a replacement for God. God is in charge of evolution, so what's the bg deal?

I got this in an email from the Vice President of Christians in Science:

quote:

To use God as a basis for specific scientific phenomena seems to me to degrade him to the level of mere explanation in the narrowest sense, and to open the door to his being expelled when some alternative explanation presents itself. That is why I agree with the sentiment (apocryphally attributed to Laplace) that, for cosmology, “we have no need of THAT hypothesis”. The use of “God-in-the gaps” is philosophically dangerous and theologically unjustified. I’d say that a much more Christian/Biblical position is to argue that God is the “explanation” (cause) of ALL phenomena, whether we think we can understand them or not. That is why I cannot agree with the creationists who seem unable to see the trap into which they routinely fall. Make “God” an alternative to “evolution” (say) and if and when the particular case of evolution is demonstrated beyond reasonable doubt, then where is God?

BTW,

Darwinism died in the 1940's. It is a case of Darwinism is dead, long live Neo-Darwinsim.

Darwin knew nothing about genetics. The main failure of The Origin is its description of heredity. When Mendels work was rediscovered, in the early 20th century there was a crisis when it was seen as an alternative to Darwinism. It was Biologists like R A Fisher that showed they actually supported each other.

So, Darwinism is a failed theory. Evolution is not. It is a very strong, powerful and well supported theory with no serious detractors.

The hypotheses about how life began on Earth is not so strong. This is not part of the Theory of Evolution, though. The ToE starts when their is something to replicate.

Two points

(1) I'm a bit surprised to find Gould linked with Atkins.In "Rocks of Ages" Gould regards himself as a (Jewish) agnostic....and he is a lot more eirenic than Atkins by a lnog, long way

(2)Thank you Sceptical Atheist for forwarding the E-mail to us.I would be extremely wary of using a scientific model as evidence of God' existence.....hence my reservations in a different thread re the "God" particle.At the moment I think that Evolution is the most likely theory ....like all scientific models this has to be tested against observational evidence of course.
It may surprise you but I have actually a lot of sympathy for Laplace here.As Galileo said in his Letter to the Grand-Duchess Christina ,both the Bible and the "book of nature" are both sources of truth;and Galileo warns against using certain scriptural passages as argument against Copernicanism,arguing instead that Moses accomodated himself to the common person in his use of language.This was also Calvin's argument....

It's good to distinguish between those who want to uphold young-earth creationism, and those Christians who believe in evolution but as controlled or established by God as the supreme designer, rather than as a purely random process.

I took a course in this stuff last semester, it was fascinating to see all the different approaches and this is a v trendy area just now. However, Gould isn't much of philosopher - see Rocks of Ages (or don't!) - and Behe's argument has been attacked by many. Al Plantinga (Christian philosopher) has an interesting argument that it's irrational to believe in evolutionary theory if you're *not* a theist, the idea being that it's hugely improbable otherwise. Stephen Stich (not a Christian) argues that there is no good reason for thinking that we would have evolved a reliable reasoning process, given what the evolutionary theory tells us (i.e. one that tells us the truth, as opposed to enabling us just to survive by whatever means). And as Sceptical Atheist says, evolutionary theory has nothing at all to say about how life began.

This could all be good for the church, but (in the US at least) people tend not to be aware of these arguments. Rather, they are either fundamentalist, young-earth types, or naturalists who think that random evolution is 'fact'. I hope this changes...

Sorry if this has been a boring post! I can get some good references on this stuff if anyone is interested though.

I'm not sure that this will affect theology that much, as I never saw theology and evolution to be inimical except with regard to the creationists. What I hope it will do is take the wind out of evangelical atheists like Dawkins who I find somewhat aggressive and uncompromising with regards to any kind of religion at all. The actual empirical evidence for human evolution is pretty small and is subject to regular revisions, such as the new info on carbon dating and its accuracy. This doesn't mean it's wrong, but that a certain amount of faith is required to go along with it! If this results in a lessening of dogmatism on all sides then so much the better.

I have to say that I don't accept the initial premise of this thread:

I don't think anyone in mainstream science has any more doubts about natural selection than they do about Newton's laws.

There is, alas, a ghetto-like mentality in some Christian circles, thinking that creationism (usually of the "Young-Earth" variety) has to be defended come what may.

I think Behe and his Intelligent Design ideas is just another more palatable manifestation of the same thing.

People who talk about evolution in terms of "random processes" or "chance" don't understand it. Natural selection means that the dice get rolled until you get the "right" result. We wouldn't be here to tell the tale if the rolls didn't come right in the end on some planet somewhere and this is the planet.

Posts on this thread regarding the philosophy of Darwinism, neo or otherwise, as a ‘fact’ of science, not a theory are interesting, but these answers are missing the point of this thread. Can we leave them for another thread, please?

Let's start to think outside the box.

Let’s just say that Behe is right, and a step-by-step development of cell mechanic can not be proven scientifically.

Just say, what Stephen said in his thread: “At the moment I think that Evolution is the most likely theory ...like all scientific models this has to be tested against observational evidence of course” is shown up by to be no more than wishful thinking on the part of philosophical atheists. What then will be the outcome for the church?

If God is no longer confined to pre-time and subjectivity. If God is active in the universe, what then happens to our theology?

The church suffered a huge identity crisis in the 20th century because of Darwinism. Demythologisation became the dominant theology as Christians tried to shoe horn the Bible into a Darwinian understanding of life. Doubt over the virgin birth and resurrection were the inevitable conclusions of this new theology, because how could Jesus be resurrected by a God with no power in the Universe?

Can we put our prophetic minds together and imagine, at least for a minute, what our theology will be like without Darwinism? (I’m not talking about creationism, young earth or old earth). Or are we so entrenched in a Darwinian worldview that we can not stretch our minds that far?

When we are no longer told that God can not act in space-time, what will the outcome be for the church?

If theistic smugness is the most obvious result, then God please have mercy on us ;-)

I would take issue with this. The evidence for human evolution in general is large and strong.
What is unclear is the actual path it took. We do not have DNA from Lucy so it is controversial whether she is a direct descendant or a cousin. She is someone in our family tree, though. We can be sure of that.

Carbon dating is subject to revision, but if we use it carefully it is accurate. Just this week, there was this BBC News Story which shows that Carbon dating is accurate back 16,000 years and is becoming morew accurate before that.

Further to the point on Carbon dating....

The new evidence would suggest that things are older than previously thought, which is bad news for Creationists.

But of course Carbon dating is not relevant here as it is applicable over thousands of years only, people use other radioactive decay chains to date back older stuff.

Whatever the errors in dating methods may or may not be, they are not of the order which Young Earth Creationists would require - a factor of nearly a million!

It is always dangerous to inject religion into any type of scientific inquiry. One of the main reasons for this is that God is an inherently unscientific premise. Which is to say that it is impossible to test most people's conception of God under laboratory conditions. In other words, it is impossible to confine the deity to a beaker. What the assumption of God DOES do, though, is to stifle or kill off other lines of inquiry. Not by Inquisitorial censorship, but because the actions of God are typically assumed to be beyond the realm of science. (i.e. non-replicatable and outside the laws of nature.) For example, if you assume that disease is caused by the wrath of God, there's not much you can do about it, as it is God's will, and thus no progress is made in medical research along those lines. On the other hand, if you assume that diseases have worldly causes, you become naturally inclined to study and research this phenomenon in order to discover some remedy.

Neil, sorry if I'm staying from the point you wanted to focus on but I think it's relevant. The pre-Darwinist theological model already incorporated much Deism as a result of Newtonian influence: God as the "Divine Watchmaker". Creationism was accepted all too readily and became the standard theological paradigm that no-one thought much about. Darwinism gave the church an enormous kick up the backside and forced them to adapt to changes in knowledge. It did not however, as far as I can see establish deism as the norm. What was established in the 20th century was an equally sloppy idea that science had all the answers and theology should be relegated to the sidelines to which science had relegated it. Much of this so-called science was sloppily thought out and unproved : to whit, eugenics etc.
Various disasters, better science and really freaky dicoveries like quantum theory suggest that we can be nearly as sure about our understanding of the universe as we thought. The hominid fossil collction would fit on to a billiard table and the gaps in the evolutionary record are immense. It's been described as like trying to understand the plot of War and Peace from seven words chosen at random. Saying we know it happened but we don't know how seems to be a contradiction in terms.
I don't buy it that science proved God couldn't act in space time. That's just the feeble argument of a few scientific fundies. If you can't prove He/She/It is there or not scientifically, how can you prove how He operates ("My ways are not your ways"). Consequently, unless you are a creationist, Darwinism should never have bothered you that much in the first place.
Incidently, in Islam this is pretty much a non-issue. Science has traditionally been seen as a form of worship: understanding the creation helps you to understand the greatness of the creator. Could we not learn something here?
 
Posted by The sceptical Atheist (# 379) on :
 
The Hominid evidence would need much more than a billiard table. Just check out the photo's in Donald Johansens "Lucy: The Beginning of humankind." They have a picture of a very long table full of fossil hominids just from the one site that they were working at. The famous Leakeys were finding just as many if not more and there were plenty others doing the same. That was in the 1970's!

Well, I hear on the radio that some scientists are having serious doubts about the evidence from mytowhateverit'scalled DNA. If their doubts can be shown to be well-founded, this would make the "out-of-Africa" hypothesis and the idea of a "super-Eve" much less likely.

Is that good or bad news for creationists?

"The twentieth century would be incomprehensible without the Darwinian revolution. The social and political currents which have swept the world in the past eighty years would have been impossible without its intellectual sanction. ... The influence of the evolutionary theory on fields far removed from biology is one of the most spectacular examples in history of how a highly speculative idea for which there is no really hard scientific evidence can come to fashion the thinking of a whole society and dominate the outlook of an age. Considering its historic significance and the social and moral transformation it caused in western thought, one might have hoped that Darwinian theory ... a theory of such cardinal importance, a theory that literally changed the world, would have been something more than metaphysics, something more than a myth."

Sceptical Atheist; it was actually the eighties and okay you probably need an extra table or two now, but for a period spanning several millions of years that's still pretty inadequate.
Isaiah; interesting quotes but what's your point? Evolution may not be the clear cut irrefutable truth that some people thought it was, but I don't see a more plausible alternative at present. It's a theory that is subject to dispute, revision and questioning and that has been badly applied by some serious whackos over the years (not unlike religion)but let's not throw the baby out with the bathwater. Can't we just accept a bit of uncertainty here?

My point is that I believe there is abundant evidence for the relevance of Niel Robbie's initial post, despite other contributors to this thread contradicting him.

I think this is a very important question which should not be dismissed so easily.

I think Isaiah is still clinging to the idea that Evolution (or rather as he and the people he quotes define it) and "Darwinism" is the root of every evil in the past century.

The reality is that there are lots of facts in the universe that aren't pleasant or agreeable, but are still true and quoting lots of people with axes to grind like Denton doesn't make them less true. Neither does it help to extend the whole idea of "Evolution" to areas where it doesn't actually belong like cosmology.

I think people have to come to terms with the fact that evolution is about as solid a fact as you can get. Attaching all sorts of connotations to it and attacking it for those supposed reasons is just an example of a strawman argument.

There is nothing wrong with the notion (if you believe in God) that God guided evolution along. It isn't necessary, but it is a respectable belief.

What is wrong is attaching all sorts of stupid philosophical ideas to evolution and making out that people like Hitler based their ideas on it. That is what these Creationist people do - however they lie and misquote freely in the process. How they can do that escapes me - perhaps it belongs in the "Taking God's name in vain" thread.

Well I must have totally missed the point of the last century's theology (quite possibly!).
Um... I've always believed in an intelligent agent behind it all and have never noticed that conflicting with my faith. Hence I jumped to the conclusion that you were asking what the outcome would be for how the church saw itself having been proved right. However as I read the thread again, you are asking how it will affect how we see ourselves and our faith...

Well it won't change a lot for me personally.

As for the church, it SHOULD mean that we are more confident and feel affirmed in our previous declarations, surely? Which I still think will lead to smugness!

If you are saying that we aill be moving from an assumption that gradual change and improvement should underpin our lives, I don't know the answer. As an individual it won't change my view, I don't think - at least, not more than it's changing anyway. I have never accepted 'Evolution' (N.B. as it is in its popularized form) as an unchallengable theory - nor does the possibility that it might be, destroy my faith.

I just find it fascinating to learn about all the things we have the ability to question, whether or not they are provable! Wouldn't it be great if the effect on the church was that people began top worry less about proving their own point?!

Is Mr Collins actually answering the question or getting a little "Hellish" in his attitude?

It's a big statement to call all creationists liars and misquoters. I take exception. I am a creationist who takes a serious interest in science and quoting all scientists fairly. I have never fibbed about it either.

If Mr Collins disagrees with the question itself, then perhaps he could say so more graciously. I had hoped we could all be such jolly good friends.

Isaiah,

Do you accept the universe is over 6,000 years old?

If you do, then do you think there is scientific evidence to back up the claim?

If you do, then you are misrepresenting science.

If you belive on faith that the Earth is 6,000 years old or don't try to use science to support the view then I have no problem. The soon you try and use science to support your claim I will be sent to hell or kicked off for crusading.

What a load of nonsense! You quoted some creationists. I referred to them saying "These Creationists" and commented that they were liars and misquoters, a view I am unrepentant about subscribing too. You have extrapolated that, put the words "all creationists are liars" into my mouth and taken offence at that.

I don't see how anyone can look at some of these Creationist web sites etc (for example "Answers in Genesis" and "Institute for Creation Research") without rapidly coming to the conclusion that Young-Earth Creationists turn lying and misquotation, not to mention extreme rudeness to people who disagree with them, including other Christians, into an art form.

If you subscribe to their views, I'm sorry for you, I'm sure you're sadly deceived, but it doesn't make you a liar or misquoter as such.

I see no reason why this discussion should not be a friendly one if people trouble to read posts properly and not over-react to things people didn't say.

Neil,

I will try to answer your question as you posed it.

Not a lot would change at all.

Firstly even if it is (somehow!) established that certain biochemical systems or structures could not have evolved but must have been designed then the identity of the designer(s) becomes a question. Who or what designed these things?

Might an advanced lifeform of a very different sort from us have evolved elsewhere in the galaxy and designed these structures and systems and then seeded our planet with lifeforms that then evolved into us?

Let us suppose that Behe has a watertight argument against this too. Well then perhaps it was God, or a god (one of many poytheism is not ruled out) or some other form of life beyond our knowledge?

Suppose we assume it was the One God then what does all this tell us about him/her/it? Well we would have to do careful research to identify those structures and systems to make sure we understand the possible mechanisms of evolution in order to be sure that we had an instance of design. All that would show us is that he/she/it intervened in some way at some time in the world to produce these structures. But in itself that would not tell us much about this being's motives (perhaps it is a cosmic sadist that wanted to produce life to torment it).

Other theologians might regard 'God's' inability to design a universe that was able to evolve such structures as Behe talks of as not being up to much!

There would, in short be as much controversy as there is now because even if Behe's argument is correct it still leaves much about God in darkness.

Nor would it prove anything about the status of the Bible, either.

As a penultimate point, I think you overestimate Darwinism's centrality for theology about God's action in the world. The argument from design for Gods existence has had many challenges for a long time (from David Hume in the 18th century for example). Similarly issues such as the problem of Evil, questions of free will and determinism, morality, all play a major part in conceptualising whether or not and how God acts in the universe and have been around a heck of a lot longer than Darwinism. These issues have shaped theology too.

Finally I must say that Behe's arguments are not convincing and have been well answered (for a very good reply see Tower of Babel: the case against the new creationism by the quaker Robert T. Pennock (MIT Press) much the best book around on this area.

Thank you for your clarification, Mr Collins. I apologise for my misunderstanding.

As for Mr Atheist, how can I debate with someone who has already given the final word? I cannot present any evidence for a young earth - even by a non-Christian - without being unscientific. So what's a guy to do?

Apologies if I've seemed dismissive but I was trying to look at the question from something other than a Creationist perspective and as such it seemed a little baffling. I did say that Darwinism did pose a problem to Creationists but I wasn't sure if this was what Neil was initially referring to. If this thread was ultimately about creationism could this not have been made clear from the start? It might have saved a bit of confusion.

In Neils opening post he refered to
quote:
the unfolding ‘battle of the sciences’ between biologists on both side of the philosophical divide…philosophical atheists Dawkins/Gould et al on one side and philosophical theists Behe/Schroeder et al on the other?

Just to add confusion to the situation, you might be interested in "The Darwin Wars" by Andrew Brown (ISBN 0-684-85145-8) which details the sometimes very bitter disputes between "Dawkensians" and "Gouldians" about different aspects of neo-Darwinianism. Both camps agree with the broad picture of neo-Darwinianism; evolution of organism by selection of genetic variants.

The views of Behe et al are very contentious, and make some very big assumptions. There has yet to be a single irrefutable example of a biochemical pathway which could not possibly have developed gradually from pre-existing pathways. Without such evidence these views are scientifically very weak.

As such I find the views of "Design Theorists" (see for example the Origins website) scientifically weak. I hve several other reservations about this idea which I have outlined on this page of my website.

Posted by Neil Robbie (# 652) on :
 
Much of this thread has reinforced the conclusion I was already being drawn to having read Dawkins, Behe and co. That is that scientific support for a materialist, purposeless universe on one hand or a universe as the product of an intelligent agent on the other hand is beyond the current investigative capabilities of human intelligence. A simple 'we don't know' neatly summarises the current results of scientific investigation to the origin of life.

So, back to my original question. Darwinian philosophy (as distinct from Darwinian theory) has affected or infected almost every aspect of our theology over the last century. Such a dominant worldview could not have failed to seep into every nook and cranny of the church's life.

Wulfstan's observation that 'Dawrinism gave the church an enormous kick up the backside' is apparent and indeed the emergence of Darwinism has had many beneficial spin-offs for the church. However, his later argument that 'unless you are a creationist, Darwinism should never have bothered you that much in the first place' IMHO is like saying that when you spill the contents of an oil tanker in the sea off Alaska, it only affects the water quality. What about the oil that seeps into the sand, kills the fish, gets into the throats of otters, strips the natural oils of the feathers of birds and depletes microorganisms in the sea?

Darwinian philosophy is to Christian theology what oil slicks are to the environment. 'Liberalism' is the most obvious by-product of a theology polluted by Darwinism. What about the Conservatives, Fundamentalists, Catholics (Roman and Anglican), Charismatics and Pentecostals? Are we not all affected too? Should we not all go back over what we have come to believe is true and check if Darwinian theory (a purposeless, material, Godless universe) got its foot in the door of our theology? Let's check our feathers and clean off the unwanted oil which seeped into our understanding. Be purified, perhaps in the way God intended when Darwinian theory first emerged.

I was asked this question recently by a Christian minister: 'when did sin enter the world if man 'evolved' step-by-step?'

Taking the step-by-step 'evolution' of man, it is impossible to apply a date to the start of human rebellion against God. It is equally difficult to identify a biological, physiological or philosophical mechanism by which humans turned from God to reliance on our own abilities if change was minutely gradual. But the question assumes a prior commitment to the assumption that humans developed step-by-step from some other living organism. This is the sort of example of the pollution of theology by Darwinian philosophy I am referring to. There must be more subtle, clever affects from this worldview on our understanding of God.

I hope this clarifies my question. Can we think outside the box and see what else is suffering from this prior commitment to Darwinian philosophy?

Darwin, of course, did not invent the idea of evolution--he simply came up with the most plausible explanation yet for how it happened. Nor do I think evolution created any new problems for theology--though it did give the Deists and other skeptics a bit more ammunition (Copernicus had already given them a fair amount). In truth, science is only a problem for those Christians who believe that if the Bible is not literally, historically, scientifically accurate, the whole spiritual message comes crashing down. This brings to mind C.S. Lewis's comment about skeptics who don't believe in Heaven because the description in Revelation is a bit over the top: "If they're going to be take that attitude, they shouldn't be reading books that are written for grownups" (misquoted from memory).

Who needs a date for the Fall? As someone once said, history is what happened one time, myth is what happens all the time. The world is always falling and always being redeemed. And yes, in a historical sense (according to the flesh, as Paul might say)there was the historical fact of the resurrection; but in a more important sense, Christ is always being crucified and resurrected in us (I don't mean this in a trivial symbolic sense, either).

Evolution (Darwinian or otherwise) has never been a problem for sound theology, and if it turns out that there is some other scientific explanation for the development of modern organisms over the course of the history of the Earth, that won't be a problem either.

Regards,

Timothy

Thought the battle-axe would be needed here, but actually have little to add to what the good Mr Cresswell has said.

Except that some of Behe's 'irrecducible complexity' examples are refuted by Kenneth Miller (Finding Darwnin's God) which also makes an excellent read on scientific and philosophical levels.

Really, ID is just the old God of the Gaps married to the Argument from Design, the first of which is philosophically dangerous, and the latter long ago refuted.

I subscribe to Gould's approach of Non-overlapping magesteria.

THe problem is, people really believe this.
I had a LONG debate last night with my fundie flatmate (chick tracts left around the living room, that kind of thing...!)

And in the end, it came down to "If the first three chapters of Genesis can't be relied on, then none of the bible can be relied on". I was clearly on very dangerous ground suggesting otherwise.

HOW ON EARTH do you convince someone that you can be a bit more open minded about Genesis without being a "raving liberal"??? Particularly if that person doesn't have a scientific background and is suspicious of science?

(I'm sure she's off now to pray that the Lord will reveal to me the error of my humanistic thinking. Particularly as I also informed her that I didn't think the Catholic church was the Anti-Christ... Aaaaarrrrgh )

Any thoughts????

You have little chance.

You can visit Talk Origins (link above) and my site for a lot of material that shows that the science is bollocks, but that won't get round the philosphical problems.

(Actually, the Chick Tract Big Daddy is a hoot - at least one major scientific misunderstanding or misrepresentation per frame)

There is no logical link between 'Genesis 1 is literally true' and 'the Gospel of Luke is a historically reliable account', but folk make it.

My feeling is that if the belief that Jesus is alive needs bolstering with the idea that every word in the collection of books surrounding the subject is literally true, then the whole construct should fall.

Jesus was raised from death because He is alive now in His church and people, not because some old text says He is.

An alternative approach could be to point out the size of the membership of an organisation such as Christians in Science (currently in excess of 600) which has a declaration of belief (signed by all members) including
quote:
I declare my belief in the triune God as creator and sustainer of the universe, and my faith in Jesus as Saviour, Lord of all and God.

and
I acknowledge the Bible as the Word of God and its final
authority in matters of faith and conduct.



It does beg the question that since the vast majority (if not all) CiS members do not accept the hyper-literal reading of Gen.1 how do they honestly sign the declaration, especially with the second clause I quoted.

The answer of course is that the young earth creation position is a modern invention (ie: basically post-war, initially proposed by Seventh Day Adventists to support their claim that the 7th day, Saturday, should be the day of worship rather than Sunday) that creates more theological and doctrinal problems than it purports to solve, and treats Scripture with a great deal of disrespect by elevating a superficial "plain reading" to a point where it teaches something the original authors (and I include God as one of those authors) didn't consider to the neglect of what those authors wanted to say.

Alan, did try that one...

She didn't even accept that my position was mainstream Christianity! (the early church would have taken it literally, so Augustine & co were clearly wrong. After all, they were catholics too, so obviously beyond the pale.)

The only bit of my argument that seemed to get through was when I asked her to "suspend belief" and imagine that she was shown totally convincing evidence for evolution. Would she reject the whole of the bible, or reinterpret the Genesis account?

She agreed that she would have to re-interpret it (RESULT!!!) but couldn't imagine that there would ever be convincing proof.

I did then try to explain that I thought the evidence *was* convincing, but she obviously didn't buy it.

What frightened me was that she perceived any questioning as a threat: ie, you've got to be so wary of "clever" ideas because they're subtle traps of Satan.
The idea of engaging with secular ideas from a christian perspective was totally alien to her.

I've never thought of myself as a Liberal before...!

So God created all the fish and birds, then the animals and mankind (both genders), then...erm....created the man, then the animals and then the woman.

It really sounds like two accounts to me.

Whilst she's at it, if the Bible is literal, who caused David to take a census of Israel?

quote:
2 Samuel 24

1 Again the anger of the LORD burned against Israel, and he incited David against them, saying, "Go and take a census of Israel and Judah".


Or

quote:
1 Chronicles 21

1 Satan rose up against Israel and incited David to take a census of Israel.


There are lots of problems for literalists.

Your problem is for her to understand how the Bible is not literally true in every word without damaging her faith, which is, in the end, more important.

You are right to distinguish the theory from the philosophy (though you confusingly refer to Darwinian theory as meaning that the universe is ultimately 'a purposeless, material, Godless universe' which is a mistaken inference. I assume you meant 'philosophy' not 'theory').

Science seeks to understand how the universe works and is necessarily non-theistic (not atheistic) in its methodology. It looks for the natural laws and patterns present in the world. It does not invoke God in its explanations because if it did so science would either grind to a halt or else it would have to investigate things further anyway to make sure there was not a natural rather than supernatural explanation after all. But to mistake a non-theistic methodology for a claim that the world really is without a God is a mistake. Some evolutionists do claim this but not all.

Those of us who accept the broad outline of evolutionary theory would not see it as polluting theology. Not all philosophies arising from Darwinism are atheistic.

You say 'Such a dominant worldview could not have failed to seep into every nook and cranny of the church's life.' This is an enormous claim which i find unbelievable. Where in the theology or life of christianity does 'a purposeless, material, Godless universe' figure so pervasively? You mention liberalism but the vast majority of liberal Christians do not believe in 'a purposeless, material, Godless universe.'

Do you have any other examples?

Reading an article by Dawkins about the recent Darwinism conference, by the time I got half way through the thought that was in my mind was "This is fundamentalism". Yes it seemed that the fundie label should not just be thrown at religious people but the likes of Dawkins is getting close to being an evolutionary fundie.

I later read an article in the Guardian (a liberal british daily newspaper) which objected to the theories being put up at the Dawinist conference, and although they did not use the fundie label their objections seemed similar to mine.

I am not writing this to support 7 day creationism, but rather to wonder where the debate is going. To mind mind it is heading towards somewhere like the end of Animal Farm
They looked at the Bible fundamentalists and the Darwin fundamentalists and could not tell the difference between them

Seriously, as for your flatmate, I would summon up a prophetic glint in my eye (well it'd appear, I'm afraid) and ask her what issue she is trying to avoid by concentrating on an unprovable red herring. Undoubtedly there will be one, though she may not know that herself yet. Reason won't work - I know that, cos I used to believe exactly the same and drive MY flatmates to distraction!

Liberalism ain't Godless. I seem to be moving towards some ever more liberal point at the momnet, and i can honestly say that letting go of my evangelicalism has been the most profoundly Christian experience I've had in 26 years of belief. Cos it's frightening, unknown, and therefore uncontrollable (he's not a TAME lion). I have to trust god that H'ell get me through this and either out the other end or into the Place Where He Wants me.

But Godless? I have never been as free to love others as i am now I have lost so many of my old prejudices (which really all sprang from fear of taint by association).

Don't knock it till you've tried it!

Hi all,

as a proto biologist ( ie an undergrad at the same unoversity that dawkins is based at, im going to take an evolution course next year, and from what i've heard, dawkins makes rather a small appearance. he's not the only or most influential "evolutionist" ( why does that word always set alarm bells ringing in my head ). Just because he's very vocal in his atheism doesn't mean that just because he uses darwinian philosophies (rather than darwinian theory) to justify his atheism, doesn't mean he's wrong about the biology of the process (although that is a whole other kettle of fish...)

while dawkins accuses believers of using a "skyhook" like God to support our worldview, he simaltaneously invokes the skyhook of free will to support his ( or so it seems to me.

a really interesting essay by Theodosius Dobzhansky ( influential evolutionary theorist and devout christian ) is here

i think i might chuck in a few quotes because, quite frankly, he's a lot more eloquent than me

young earth ?

quote:
One can suppose that the Creator saw fit to play deceitful tricks on geologists and biologists. He carefully arranged to have various rocks provided with isotope ratios just right to mislead us into thinking that certain rocks are 2 billion years old, others 2 million, which in fact they are only some 6,000 years old. This kind of pseudo-explanation is not very new. One of the early antievolutionists, P. H. Gosse, published a book entitled Omphalos ("the Navel"). The gist of this amazing book is that Adam, though he had no mother, was created with a navel, and that fossils were placed by the Creator where we find them now ? a deliberate act on His part, to give the appearance of great antiquity and geologic upheaveals. It is easy to see the fatal flaw in all such notions. They are blasphemies, accusing God of absurd deceitfulness. This is as revolting as it is uncalled for.

quote:
organic diversity becomes, however, reasonable and understandable if the Creator has created the living world not by caprice but by evolution propelled by natural selection. It is wrong to hold creation and evolution as mutually exclusive alternatives. I am a creationist and an evolutionist. Evolution is God?s, or Nature?s method of creation. Creation is not an event that happened in 4004 BC; it is a process that began some 10 billion years ago and is still under way.

apologies for the huge amounts of quotation, but its a long essay with lots of good bits.

yours,

doug

May I clarify. My initial post merely contrasted the dogmatic evolution-is-unquestionable statements made by some writers in this thread with the evolution-is-highly-questionable statements of some modern non-Christian scientists. It seems that, because I was prepared to question evolution, it was presumed that I would want to scientifically defend a young earth - a proposition which I was told would not be tolerated. I then pointed out that there was no point presenting any evidence under those circumstances. Then, happily, some of "the board" were ready to consider any evidence for a young earth more openly.

As it is, most of the debates are available on the web, and I don't need to fill up this thread copying and pasting them in here. All existing pro-young-earth arguments are already "PRATT" to my objectors, and I don't have any novel new theory of my own to present.

Dogmatic evolutionists who have considered all contradicting evidence as "PRATT" need to recognise that their theory is not conclusive. In other words, the previously "PRATT" evidence is no longer so easily dismissed. I think that a fair evaluation of the scientific evidence in the age of the earth debate also shows that there are difficulties on both sides. Given time, I expect that "PRATT" labels will be thrown around less confidently in this area also.

This said, I believe that the very nature of our discussion here reflects the relevance of Mr Robbie's initial question. The fact we should all recognise is that our presuppositions do, of course, influence all our thinking, our theology, and even our scientific evaluation.

It is certainly demonstrable that Darwin did not so much devise the theory of evolution because of overwhelming evidence as he did devise the theory and then go looking for evidence. As we all know, he admitted that the lack of evidence was his biggest obstacle. Over the past 20-30 years the Neo-Darwinists have had to face a growing problem of the same nature. And, dare I say, I think the age of the earth issue will eventually come into the same arena.

If we presuppose a theory or belief about the origin of life, its development, or even the age of the earth, we will want to interpret the data to support our ideas and dismiss all other interpretations as "PRATT." We see these excesses in both the evolutionist and the creationist camps. There is no such thing as neutrality. There is no "pure objectivity" even in the laboratory. It is the myth of modern science that the "evidence speaks for itself." It is the presupposition that speaks through the evidence. And, as Cornielius Van Til demonstrated, this is unavoidable.

This, in my view, is why the special revelation of Scipture is primary and why general revelation, including the natural world which we explore through the sciences, is secondary. If we presuppose the authority of Scripture, then we have a standard to refer to in our scientific pursuits. I am not saying that we ignore those problems in the laboratory that seem to contradict Scripture, but I am saying that we should always accept Scripture as the primary evidence. Our first step in science is exegetical. And even within this framework our human limitations and sinful bias will hinder our work. Nevertheless, I believe that when the Scriptures are properly exegeted and the natural data are correctly understood the two will be in harmony.

If we are to do justice to Mr Robbie's question, then I think we need to debate this area of presuppositionalism and epistemology.

Isaiah - speaking of presuppositions, perhaps some explanations are in order.

SA and I are both veterans of the web debates on this issue - I have recently 'resigned' as it were from debating on the OCW's debate board because of the pathetic insult based 'debating' technique of some of the YECs there, but also for another reason, and it's tied up with the acronym PRATT.

You will recall it stands (pace Pasco) for 'Point Refuted A Thousand Times', and the reason we coined it was that we were fed up with answering the same points, that have indeed been refuted many times, but which uninformed creationists still raise as objections to mainstream science.

Such might include:

* No transitional fossils
* Speed of light slowing down
* Speed of stalactite growth
* Mt St Helens creating mini 'Grand Canyon'
* Earth-Moon regression
* Second Law of Thermodynamics

for starters. For a complete list, my web site has a consideration of a particularly rich collection of PRATTs on this page.

It is not that we are saying that any Young Earth evidence is automatically a PRATT. What we are saying is don't bother using any PRATT evidence because it'll be pumped overboard with the rest of the bilge.

Agreed. And one of the similarities between the worst of the fundamentalists in both the religious and scientific atheist camps is the inability to recognise that presuppositions are not unchangeable; as a scientist I enter the lab with a theory to test presupposing on the basis of all I know that the theory is right, after a series of experiments that don't work and revisions to the theory I may be forced to start questioning ny underlying presuppositions (I'm now missing the time when I used to do that sort of lab work). What is true of science is true of Christian theology; if I start with a supposition that the Bible is the inerrant Word of God in all details then there are things I could expect (for example: internal consistancy of the Bible, consistancy between the Bible and scientific, historical and archaeological evidence), when problems arise I could refine my theorising (try to harmonize internal inconsistancies or do some un-scientific things with data and call it "Creation Science" for example); when these re-theorizings become to convoluted isn't it time to address the underlying presupposition?

The pressuposition that science is "objective falsifiable" is one we addressed on the "An Introduction" thread. There has been a number of other valid philosophies of science, however they often fail to take account of how scientists actually work. Most scientists don't have a thought out philosophy of what we do, we just get on with exmining the physical world trying to be as honest and objective as possible.

quote:

Both Scripture and science look at the work of the same God, albeit from different aspects. Harmony doesn't necessarily imply saying the same thing. Two singers can be in harmony without singing the same words, and in such occasions the whole duet is greater than the sum of the parts. And it isn't just a duet we're looking for, I want to see the harmony in the different views of sciences, historical and literary studies, arts, Church Tradition and Scripture and other sources of knowledge; I want a harmonious choir.

No I think you went into the argument with "shields up". There are people who are Creationiists who aren't Young Earth Creationists. However your initial post was a collection of quotes culminating with some YEC stuff. You didn't make any comment apart from "Hmmmmm....".

No if you had something new we'd have listened. But the characteristic of so much YEC stuff is that the same arguments are trotted out each time, whether it is about the Second Law of Thermodynamics, the Sun shrinking, comets, interplanetary dust, radioactive dating, salt in the ocean, helium in the atmosphere etc etc etc.

We see these arguments scrutinised in microscopic detail and thoroughly refuted by people who live and breathe the subjects concerned, and yet the YEC arguments never get changed. The most they ever do is lift bits hugely out of context.

Well it would be interesting to see something new instead of the tired old arguments trotted out by YECs.

quote:

Dogmatic evolutionists who have considered all contradicting evidence as "PRATT" need to recognise that their theory is not conclusive.

It's the nature of "theories" that they aren't ever conclusive. They are postulated explanations for sets of observed facts which are held until some conflicting evidence turns up. If such evidence does turn up, people modify or possibly discard the theory concerned. That is how people move on.

I think that is total rubbish. Sorry.

quote:

So what? That's the way people do things. You see one set of facts A, B and C, devise your theory, say "well I'd expect to see X, Y and Z if my theory is correct" and then go looking for X, Y and Z.

For example Einstein devised his General Theory of Relativity in 1915 and said if it was right, the sun would deflect starlight passing close to it. People looked for that in 1919 at the solar eclipse then and sure enough there it was.

Darwin postulated his theory of evolution in response to one set of facts (e.g. finches) and then looked for other evidence, such as transitional forms. He may not have found those, but as we know, plenty of transitional forms have turned up.

You can dare say it, but I'm sure you completely wrong.

Gentlemen, I'm sorry for interrupting the flow of your debate, but somewhere back on page 2 Glenn asked: 'Do you have any other examples?'

You may have already gathered, Glenn, that I am a bear of very little brain. Starting a discussion along the speculative lines of a world without Darwinism would, I hoped, produce some examples of polluted theology from people with minds far greater than mine. Perhaps I jumped the gun. Perhaps we need to wait until the muddied waters clear before our minds try to grasp the effects of the influence of Darwinism on the church. Perhaps, only with hindsight will we see the errors of today. In the mean time, I'll put my limited cranial capacity to the task of an example, but don't hold your breath.

Perhaps Gill's very first response to this thread is the best conclusion we can draw, when she said 'I suspect it would just result in a revival of smugness in the church!' Smugness will no doubt sadly emerge, but hopefully a renewed confidence in our faith in the resurrected Christ will emerge with an equal boost to work of His church in this world.

Hopefully

There has been some mention of Dawkins and I mentioned his book 'Unweaving the Rainbow' at the start of this thread. In his preface he states:

quote:
'I believe that an orderly universe, one indifferent to human preoccupations, in which everything has an explanation even if we still have a long way to go before we find it, is a more beautiful, more wonderful place than a universe tricked out with capricious, ad hoc magic'.

The 'ad hoc magic' he scoffs at is the same 'ad hoc magic' which makes most rational people balk. Horoscope writers, fortune tellers, spiritualists, crystal ball gazers, spoof healers, psychics and so forth.

Dawkins goes on to marvel at the properties of light and the eye, the physics of sound and the ear. He longs for a world excited about the wonders of the universe, for poetry to be inspired by science. As an engineer, I share Dawkins' excitement of the discoveries of science. I share his thrill at the wonder of it all.

Dawkins is not only amazed by the natural world, as I am, but at musical works and poetry, and he rightly applauds the composers and the poets. I find myself agreeing with almost everything Dawkns says.

What struck me as I read it was Dawkins' sense of wonder at the complexity of the universe. Though, sadly unlike his applause for composers and poets, he refuses to applaud the composer, the designer, the engineer of the universe.

I wonder, in his worship of the natural world, so beautifully described in 'Unweaving the Rainbow', if Dawkins has unwittingly exposed the greatest false idol of our time?

Neil

quote:
'Yes, they knew God, but they wouldn't worship him as God or even give Him thanks. And they began to think up foolish ideas of what God was like. The result was that their minds became dark and confused. Claiming to be wise, they became utter fools instead. And instead of worshipping the glorious, ever-living God, they worshipped idols'. Romans 1:21-23 (NLT).

I took this as asking for more examples of theology "polluted by Darwinianism", the example given being "liberalism". Since I don't think even liberalism is a product of Darwinian philosophy, I'm afraid another example is beyond me.

Besides, what is wrong with theology incorporating good science? Theology dependent on speculative and controversial science (by which I might include, say, the idea of memes - not that I'm aware of any theology based on this) is on shaky ground. But the broad picture of Darwinian evolution is so solidly founded that there is no danger there.

Don't really see the link between Darwinism and 'faith in the Resurrected Christ'. Why not pick on quantum mechanics, or oxidation numbers?

Or rather I do, but I think it is bogus. Am I right in thinking that 'Darwinism' allows a chink of doubt about the existence of God? Afraid not - there were atheists long before there were natural explanations for things.

Looking back at the OP, there seems to be some equating of Darwinism with a natural explanation for the origin of life. Oddly enough, Darwin didn't say anything about the origin of life - he tended to see the first organisms as direct creations. What you are referring to is abiogenesis, which is not part of Darwinism or evolution and is a far more debateable area. I will not argue against special creation of the first replicators, because I have no coherent alternative hypothesis, although I suspect for philosophical reasons that there will be a natural explanation, complementing the theological one as per what Alan Cresswell was saying above.

Again special creation of species (or 'kinds', indeed) I would have much to say, because the evidence against this, and for their common descent, is very strong indeed. But mere assertion is meangingless, although much relied on by YE creationists; I would refer the reader to 29 Evidences for Macroevolutionif he wishes for substantiation.

The confusion of evolution and abiogenesis bugs mainstream scientists, because creationists dishonestly transfer doubt about the latter into doubt about the former.

I wasn't actually aware that the church had lost its confidence in the resurected Christ. Maybe it's lost its imperialist, judgemental sense of superiority, but it isn't just Darwinism that's done that. Contact with other faiths has helped to knock that one for six, as, I believe, has an increased awareness of its mission to the poor and to the rejected of the world. The Second World War was also an enormous shock to the Christian church, not least when it saw how many Christians so-called could be led into supporting, or turning a blind eye to, Nazism and Fascism.

Not being a scientist, I can't add to any of the arguements in favour of evolution. But I have never seen how the Bible can support such a view as Young Earth Creationism. Apart from the dodgy numbers game you have to play to get the dates to tally, where is the difficulty in seeing the Bible as expressing truth through poetry, symbolism, mythology, analogy, rather than having to be totally literal all the way through?

In any case, it's an awful waste of time to spend trying to argue for a particular interpretation of a few verses in Genesis. What is the YEC theology of creation? What - apart from the "fact" that it happened in six days - difference does it make to their spiritual lives that God is a Creator?

Because in the end, that is what matters. Whether God created the world in six days in 4004BC or over millions of years through evolution is neither here not there. What is the impact of God's creativity on our own lives? On the way we treat the world around us?

Seems to me that YEC's spend an inordinate amount of time avoiding that question.

and while writing that Neil posted again on Dawkins, so regarding Dawkins. I haven't read much of his more recent stuff (River out of Eden, or Unweaving the Rainbow), which from reviews I gather are repeating his earlier stuff while taking the more speculative and philosophical further. Since I found this material very unconvincing in his earlier books the later ones aren't at the top of my reading list (I'll get round to them eventually).

Dawkins is undoubtedly a very gifted communicator, and an able scientist. And if anyone wants a good non-specialist introduction to genetics and evolution his earlier works (eg the Blind Watchmaker) are a good read. However he then makes a step of faith from a description of science to atheistic philosophy at least as large as the steps of faith he derides others for making; at that point I part company with his ideas.

As writing this, Alan and Stevewal have posted.

Alan, I am interested to know how you do not make a link between liberalism and Darwinian philosophy.

My limited understanding is this.

If Darwinian philosophy (neo or otherwise) states that the universe is purposeless and material, then I can see your objection.

However, if the same statement of philosophy is made in a different way: that there is no way for God to operate in time-space, but that God might exist outside time-space and humans can have no way of knowing God's existence, as Darwinism often claims, then is this not the starting point for demythologisation? I understand demythologisation to be the starting point of liberal theology.

I might be wrong. What is your thinking on this?

Neil


BTW...Dawkins bearly scrapes over 'O' level physics in 'Unweaving the rainbow', it doesn't make the read less interesting, but the message is clear...'bow down and worship creation'...or should that be the natural world?

Darwinism makes no such claims. It claims that species arise by common descent with modification from previous species.

You might want to read Kenneth Miller's Finding Darwin's God which deals with this question in some detail.

In a nutshell, however, if God can be seen working through the contingency of human history, He can also be working in the contingency of natural history, without requiring Him to overrule the natural laws He has set in place.

The philosophical positions that "the universe is purposeless and material" or "God might exist outside time-space and humans can have no way of knowing God's existence" are older then Darwinian evolutionary theory, and not dependent on it, although some philosophers holding such positions may use (neo-)Darwinian science to support their position. Some people, like Dawkins, support such a philosophical position almost exclusively from Darwinian theory which actually makes their philosophy much weaker; extrapolating from science into philosophy (which is beyond the realms of scientific inquiry) seems to be a strange thing to do when the same position can be reached by philosophical reasoning. Not that I necessarily agree with such philosophical reasoning, but it is at least more honest than Dawkins approach.

Way back in the thread, there was some mention of the church being refined by the challenge of Darwinism. I agree that imperialist and judgmental attitudes may well have been removed by that challenge.

But what about the effect of Darwinism on the church's role in looking after the poor and needy which you mentioned? Is there a link between the crisis in the church last century caused by Darwinian philosophy and the fact that the church lost the will to care?

If the church began the caring professions, why did they end up in the hands of the state in the form of the NHS? If the church was caring for those who could not support themselves, why was removed from the church and put in the hands of the Welfare State? Is there a link? There's certainly an approximate chronological one.

What about mission? Why did churches empty if they did not lose faith in the resurrected Christ? My hometown in Scotland can be no different from most, where 6 full post war churches are now all but dead on their feet.

What else was around last century to cause the crisis of identity if it wasn't the effects of Darwinism? Don't mention the war

Are the 'scientific' supports of philosophical positions not the key to understanding why the church lost its confidence? We know now that the 'scientific' basis of faith in a purposeless universe is shaky, but that's with the benefit of hindsight.

In the 1960's when Darwinism and science at large were in the ascendancy, the church was on the back foot. Instead of being able to take on science for what it really was, educated churchmen were left to squeeze God into the Darwinian framework provided for them as 'fact' and liberalism was the inevitable outcome.

Now, where to begin ....

Increasing movement of people and communication increased the awareness of other faith traditions, raising the obvious "is it right to say Christianity is better than these other options?", particularly with the collapse of colonialism removing the "superior British, Christian, society" support for the superiority of the Christian faith. Nothing to do with Darwin.

The perceived (if not actual) link between contemporary Christian teaching and the Enlightenment, coupled to the loss of faith in reason to solve the problems of the world as made patently obvious by the fact that WWI wasn't the "war to end all wars" and the horrors of WWII (sorry, couldn't help but mention the war). With the loss of confidence in the Enlightenment view of the world then the Churchs' teaching was likewise rejected in favour of alternative "spiritualities" (in which I would also include materialism and consumerism as well as religious and atheistic views). Also nothing to do with Darwin.

Just a couple of examples to show that the decline of the western church can not all be blamed on Darwin (or more accurately those who developed philosophical positions on his theory of evolution)

Neil - could you define exactly what you mean by 'Darwinism', because I'm not clear we're talking about the same thing.
 
Posted by Neil Robbie (# 652) on :
 
Karl

Thank you for asking for clarification, I’m not sure others will agree with the following definitions of Darwinism, but for the sake of debate, perhaps we can use these terms:

Darwinian Philosophy: The prior commitment to ‘natural selection’ as the mechanism for the origin of species (Darwin himself had reservations about his theory proving the origin of life).

Neo-Darwinian Philosophy: The prior commitment to ‘natural selection’ as the mechanism for the origin of species and the origin of life (by the time of the neo-Darwinian synthesis the philosophy had gone much further than Darwin first imagined and theories emerged for the origin of life – see Stanley Miller circa 1960).

Natural Selection. A term used to describe three distinct mechanisms:


  1. ‘variation within a species’ (ie finch beaks and spotted moths – see ‘O’ level biology class)
  2. how single cell microorganisms became fish, then reptiles, then birds, then somewhere along the line, mammals and eventually humans.
  3. how life began from physical and chemical goo.

For the record. I have no problem with A, it has been observed and is fact. I struggle with B, but must say ‘I don’t know’. As for C, it is statistically unlikely and chemically unproven. I believe that God made it beyond our human comprehension. It is too complex and our brains to small to cope.

Again for the record. I believe in the inerrancy of scripture, but view Genesis 1 and 2 in the following way:

The answers in Genesis are:

Then what are the questions?

On the other hand, science answers these questions:

Then what are these questions?

Now-Darwinian philosophy as defined above tries to answer the Who and Why questions which is why it directly contradicts Christian theology, which is why I have such a problem with it.

Sounds like a 'How' answer to me, not a 'Who' or 'Why'. Consequently I have no problem with it.

However, no. Natural selection has nothing to do with the origin of life. You can't select when you have nothing to select from. You need self-replicators before you can have evolution by natural selection.

That's all very well but isn't the thread called The Death of Darwinism not
The Death of neo-Darwinism?

I think that the point is well-made that a faith that is rocked by the emergence of any philosophy must be a pretty ropey one.

I do have some sympathy for people who think that taking Gen 1-11 allegorically but not the rest is a bit "Salad-Bar"-ish. But then I don't think any of it is inspired....
 


Posted by Alan Cresswell (# 31) on :
 
I've not met anyone who takes Gen 1-11 as non-literal who then doesn't apply the same "is this literal?" question to the rest of Scripture. If such a person exists then I'd agree they appear to be dishonest (unless they can honestly say they believe all Scripture after Gen 11 is literal).

Incidentally, I don't think "allegorical" is a good term to describe Gen. 1-11 (or indeed much of Scripture). Allegorical implies that each piece of the accounts says something significant. I tend to prefer the less well defined "symbolic" when refering to these accounts, but that's just personal preference.

Further to Neil's uncertainty about variation within a species, do remember that in fact the distinction between species and sub-species is a human construct, prone to change in practice and open to debate. With larger mammals, the distinctions are prone to be clearer, but for instance in the case of certain bird and insect species, the boundaries are forever being reformed.

I'd argue, therefore, that the division is somewhat false and specuous, though a useful practical tool in many circumstances. Therefore, the debate is not useful in either sphere (except for purposes of communication upon subject species).

On the third point, I think that's more certainly a neo-Darwinistic hypothesis (and I believed was described as such), but in that case is sufficiently recent in the public mind (if, indeed it is at all), so has had little if any impact on the public at large.

It seems to me that the greatest effect Darwinism had on Christianity was that it provoked the fundamentalist reaction, bringing a naive literalism into Biblical exegesis that had never before been found among educated Christians.

Whilst everyone has been posting, we've been asleep in Singapore! The 'who', 'why' and 'how' stuff will need to wait, I wrote this in response to Alan's post about the war in the taxi on the way to work...

Alan, you can be forgiven for mentioning the war, after all, it's an inevitable part of last century's rejection of God.

I propose that we need to wind the clock back further to understand the effects of Darwinism today. Starting at the Reformation we can look at the paradigm shifts which took place in Western thinking. Jim Packer summarises this neatly in his essay 'The problem of paradigms' (it's difficult to summarise four hundred years succinctly so this quote is lengthy - about 2/3rds of a page - but it is necessary for us to be able to establish a reason for the current domination of Darwinism)

quote:
With regard to God, please note that we stand at the end of four centuries of God-shrinking. In the era of the Reformation the biblical faith in God as one who rules, judges and saves, the source, sustainer and end of all things, took possession of people's minds in a vivid, clear, compelling way. But by the start of the seventeenth century Lutherans and Arminians were already exalting God's human creatures, and were thus dethroning him at a crucial point. By the end of the seventeenth century, deism, the concept of God as the mighty mechanic who, having made the world, now sits back and watches it go without involving himself in any way, was well established, and thus God was in effect being barred from this world. At the end of the eighteenth century, Immanuel Kant, the most influential philosopher for the next one hundred years, silenced God by denying all possibility of God communicating with us in words. Inevitably, therefore, with no word from God to check man's thoughts by, nineteenth century thinkers equated God with their own feelings and fancies about God, thus absorbing him into themselves in a way that promoted the atheist Feuerbach to comment that when men talked of God they were really talking about themselves in a loud and solemn voice. It was this God, God-in-the-mind as we may call him, whom Neitzche pronounced dead, and whom Marxists, Darwinists and Freudians decided in due course that they could get on better without

At the end of the 20th century, we have already witnessed the demise of Freud's ponderings and the collapse of Marxism (and its derivatives) so why does Darwinism (and its derivatives) remain so resolute (as proven by this thread)? It is because adherents to neo-Darwinian philosophy tell us (Joe public) that their philosophy is based on irrefutable scientific 'fact'? Do we believe them? Behe et al merely tell us not to take all scientific statements as 'fact'. For exmaple, no one has yet proposed an actual random chemical reaction which could produce life nor actual random mutations which produce cell mechanics, blood clotting and so forth.

Much post-Enlightenment philosophy still subtly rests on the 'facts' of Darwinism. Just listen to evolutionary psychologists and behavioral scientists on the BBC World Service and you'll know what I mean. Modern ethics, morals & law start from the assumption that God is beyond the ken of humans, and God is therefore ignored and left to the subjective realms of individuals and fringe religious groups, like Christians.

Although I did not set out to initially argue this point, this thread has been drawn to debate it. It obviousy needs much more debate and papers by intelligent design scientists to undermine Darwinism. Interestingly, my wife's Bristol Universeity Alumni magazine carries letters and reviews this month about ID vs Darwinsim. It appears even Bristol is waking up to the debate.

I go back to my initial question. To speculate on a future without Darwinism. What will be the effect on all post-Enlightenment philosophy, what will be the effect on all post-Enlightenment theology if the bold claims of the 'facts' of Darwinism turn out to be no more than dreams in the fertile minds of highly imaginative pseudo-scientists?

Exactly. In his introductory paragraph to the preface of 'Unweaving the Rainbow', Dawkins asserts again the nihilistic philosophy of neo-Darwinism. There is no why, we just are! Why is not even a valid question to a Darwinist…we are purposeless! Which is why it contradicts Christianity. The Bible asserts why we are here…there is a purpose…to know and love the creator.

The problem comes when Dawkins justifies his philosophy from scientific 'fact'. Only, people are beginning to smell something fishy about the 'fact' of science.

Does this fit with your understanding of Darwinian philosophy? If not, why not?

However, no. Natural selection has nothing to do with the origin of life. You can't select when you have nothing to select from. You need self-replicators before you can have evolution by natural selection.

We're almost at the crux of the problem with your observation Karl. 'Natural selection' is one of those weasel words used to define many aspects of Darwinian theory.

'Natural selection' means survival of the fittest reproductive organisms. To reproduce in larger numbers needs the survival of the number of organisms with the best tools for survival.

(1) On a simple level. It is a 'How' question. How were there more dark coloured moths in industrialised England than light coloured moths? The dark ones were better camouflaged from birds which ate them, that's how (gbuchanan - I have no uncertainty about variation within a species, and said so. This example is variation within a species, by natural selection - this is not a problem to either 'creationists' nor 'evolutionists' it is observed scientific fact).

(2) On a more complex level, 'natural selection' is 'how' single cell organisms become fish, then birds, then monkeys and then humans. This 'how' is under severe objective criticism.

(3) On a more complex level still, the existence of self-replicators is a huge problem to bio-chemists. But 'natural selection' of chemicals, if they were able to form simple proteins or RNA or catalysts or other building blocks of life can not explain, at this time, a random, unguided, purposeless chemical and physical reaction to produce life, biological life forms.

The problem with Darwinism is this: That Darwinists take no (1), the observational scientific fact of variation within a species, and extrapolates the origin of species (2) and the origin of life (3), from a prior commitment to atheism. Take a minute to think about it, it's quite hard to get the mind round.

Do we agree that atheism is contrary to Christianity? If we do then Darwinian philosophy is contrary to Christianity. If Darwinian philosophy is contrary to Christianity, then the biological 'education' (read indoctrination of Darwinian philosophy - religion taught in the biology class) we receive from form 1, through University and which influences all media, law and ethics around us today MUST influence the way we think about God. But how?

However long it takes to get one's mind around, it just isn't true.

It is wrong firstly in that the origin of life ("Abiogenesis") isn't part of the package, only species, and I don't accept that the latter is just an extrapolation. See
this page for example.

It is wrong secondly in the comment about prior commitment to atheism. There are plenty of Christians about who believe in the Theory of Evolution. I don't suppose, on the other hand that there are any atheists who believe in Creationism.

quote:

No we don't. It's like saying blue is contrary to green. There is a whole Pantheon of gods that neither Christians nor atheists believe in, like Allah, Hindu gods, Norse Greek and Roman gods etc etc, We just don't believe in your God either.

quote:

If we do then Darwinian philosophy is contrary to Christianity.

This is a false conclusion resting on two false premises (Darwinism => Atheism and Atheism is contrary to Christianity) and a change in terms (Darwinism to "Darwinian Philosophy").

Your argument is full of holes in my view. Whole swathes of stuff are emerging from a false conclusion drawn from false premises.

There is no prior commitment to atheism - simple as that. Darwin went to lengths to say he was not an atheist.

Kenneth Miller, whom I have 'invoked' before, points out that some of Behe's 'irreducibly complex' systems have been shown to be evolvable in the laboratory. I'll dig up the reference if you like.

Whatever Dawkins may say with his atheist hat on has nothing to do with the status of evolutionary biology, which is as darn near proven as any other scientific model.

...erm, I thought that full knowledge of God is beyond the ken of humans - unless someone here knows otherwise. Many folks who accept Darwin's theories, or theories developed from them, be they Christian or secular folk, don't base their comprehension of ethics or morals upon Darwinist theories, though they may explain the emergence of certain human norms through similar devices.

I think you need to disentangle further what you mean by Darwinism - it seems much closer to a sort-of Dawkinism or perhaps more accurately and fairly one of Don Cuppitt's more cretinous utterances. I don't think most folks here seem persuaded as to the falsifiable nature of evolution of species As to the origin of life, that's another post.

I don't feel that it's a question tho. Or rather it's one of those loaded questions which pre-supposes certain attitudes in those who respond. (ie agreement that Darwinism is on its last legs. Which - as far as mainstream science is concerned - is a nonsense.)

A discussion on whether Darwinism has had any effects on modern theology or modern society could be an interesting one, and there have been a few contributions to this already. If you're determined that the thread should focus on this area, why not re-introduce the topic with a more neutral question?

The one time that "Darwinism" oversteps its brief is when it is used as controlling metaphor for something that is not biology.

There is far too much evidence in favour of evolution to dismiss it. However, "evolution" has been used to justify certain economic theories, certain racist theories (eg that white people are evolutionarily superior to black people), and has seeped into psychology and other areas where it doesn't have any place.

Usually, though, it picks up on two things which are distortions of evolution, and especially Darwinism. First, there's the supposed "fight for survival" where the "fittest survive and the weak go to the wall." This is not evolutionary theory: which is not about a struggle between competing species, but about adapting to an environment. But from this, came Social Darwinism, and certain fascist and Nazi ideas used evolution in that way.

The second is the idea of progress: not new to evolution, but people tend to think of evolution as progressing upward to "better and better" species. Which isn't true Darwinism (is it Mendelian? I can't remember) but which made people think that they could be the top of the evolutionary ladder (hence scientific racism.) (Evolution is better described as a tree, and there is no "progress" as such, just a continual readaption to changing environments.)

So there have been some unintended philosphical and economic outcomes to evolutionary theory. But these largely come from not understanding the science, or from people with other agendas using it to bolster their own positions. It doesn't make the science (properly understood) wrong. However, science can never be entirely neutral, however much it wants to be. "The Selfish Gene" may be a good model in scientific terms: but when it gets picked up by non-scientists (eg economists), it can become a justification for economic moneterism.

So Neil Robbie does have half a point when he says that evolutionism has pervaded things outside science. But only half a point: the science is still intact. It's just sometimes we have to watch how it gets used.

As Karl said in a much earlier post, both he and I are veterans of this campaign. Like him, I have retired from that ring (in fact you can blame karl for my prescence. He suggested I might get intelligent answers to all my questions on this page. You ahven't disappointed).

Isaiah said that I am effectively biased and so will not accept things because I will automatically assign them as a PRATT.

I will listen to any evidence, I will listen to anything that Isaiah has to say. What I would expect is a clean debate. If Isaiah is willing to admit when the evidence shows something and will acknowledge it as such I will debate with him. I will obviously be bound by the same criteria.

I have obviously taken this very personally, but as I have said, this is my crusading territory. I know the ground and I am willing to stand up for the Truth on this point.

I've evidently shot myself in the foot. Caty, you identified the problem nicely...if we want to speculate on a world without Darwinism, I should never have called this thread what I did. Never mind, I'll save it for another day.

I'm beginning to feel like Job. Is there anyone there who can see the conflict between philosophical naturalism (neo-Darwinism) and Christianity?

Rather than paddle about in secondary and tertiary issues of scientific observation, can we take the discussion up to the primary level of the undergirding philosophy of Darwinism? Richard Dawkins opening paragraph in his preface to 'Unweaving the Rainbow' writes:

quote:
A foreign publisher of my first book confessed that he could not sleep for three nights after reading it, so troubled was he by what he saw as its cold, bleak message. Others have asked me how I can bear to get up in the mornings. A teacher wrote to me reproachfully that a pupil had come to him in tears after reading the same book, because it had persuaded her that life was empty and purposeless. He advised her not to show the book to any of her friends, for fear of contaminating them with the same nihilistic pessimism...Presumably there is indeed no purpose in the ultimate fate of the cosmos

Where has Dawkins derived this conclusion? He started at the thin edge of the wedge, with variation within a species (which includes non-breeding groups of mice and fish, Alan. The fish are still fish and the mice are still mice) and he has extrapolated a theory by which mice become birds, and because this mechanism of random, chance mutation is purposeless, then there can be no purpose to the universe in Dawkins' mind and therefore no God, which correlates with what Neitzche said 'God is dead'. So, (neo)Darwinism is the 'fact' which supports Neitzche's theory and by doing so it adopts Neitzche as Darwinism's undergirding philosophy as stated by Dawkins in his preface.

But Dawkins belief is 'faith' in the thin edge of the wedge proving, by fanciful extrapolation the thick end.

As many educated friends have pointed out, it all boils down to faith.

We can each make our choice.

Now, back to a point which I made. Perhaps not theology but the way of the world.

Knowing that Darwinian philosophy has, in reality, plenty to say about God, I quote a letter I wrote to the BBC World Service three weeks ago:

quote:
Sir

I listened with interest to your article on yesterday's 'Focus on Faith' regarding after hours 'religious' clubs in American schools.

The first amendment keeps American schools 'neutral' on matters of theism and faith and the article showed how this was being infringed by the use of school premises out of hours for mainly Christian evangelistic activity.

In a related matter, the U.S. National Association of Biology Teachers (NABT) promulgated a statement in 1995 to guide high-school biology teachers. An important part of that statement read:

'The diversity of life on earth is the outcome of evolution: an unsupervised, impersonal, unpredictable and natural process of temporal descent with genetic modification that is affected by natural selection, chance, historical contingencies and changing environments.'

This raises the following question: how can such a statement be classified as neutral on matters of theism and faith? The NABT's statement contains elements of philosophical belief or religious faith, that life is 'unsupervised' and the product of an 'impersonal' process. How then does this philosophical or religious teaching of biology comply with the first amendment?

The matters surrounding the issue of teaching Darwinian philosophy as 'fact' in the classroom are complex and numerous. For the proper treatment of this subject I commend to you Philip E. Johnson's (Teacher of Law at University of California, Berkley) books 'Darwin on Trial' and 'Objections Sustained'. Johnson's legal treatment of the arguments used by biologists make fascinating reading.

This is an important issue to which I hope your program can devote some research. Your website trailer said 'Also in the programme why civil liberties groups are claiming that after school evangelism is a setback for religious freedom?'

I would be interested to know if you would consider running an article on 'why civil liberties groups are claiming that teaching of Darwinian philosophy in schools is a setback for religious freedom'?

Yours sincerely

Neil Robbie


With the evidence of the above statement of 'faith' (the creed) of American National Association of Biology Teachers, does anyone still disagree that Darwinism and Christianity are in direct conflict?

Philosophical naturalism is of course opposed to any form of belief in anything supernatural.

Methodological naturalism, however, which is all that science in general and evolutionary biology included in that makes use of, is merely a tool, and opposed to nothing. It is totally in agreement with Christianity, in fact, inasmuch as it postulates that the universe is ordered and understandable.

Don't confuse the two.

Random and pointless? The problem here is that thou dost complain too much, methinks. On the one hand, you complain (quite rightly) if science starts to try to answer questions of purpose and meaning, and then complain when it fails to produce meaning and purpose. From a scientific viewpoint evolution is indeed a random process. It is the job of Christian philosophers to point out that God can act through the contingency of evolution just as through the contingency of history, rather than to fight a pointless and ultimately unwinnablee battle against the reality of evolution. Moreover, if God did, as I believe, use evolution as the outworking of His creative activity, then by opposing evolution, one is opposing the truth. That way no good can lie. We must find and contend for the truth, whatever it may be, and howsoever much we may wish it were otherwise.

Karl, I agree with you that God has set in place natural laws which govern life and which God that God can intervene as required.

I am concerned about your use of the word 'evolution', which I have tried to avoid on this thread because of its large semantic or technical range.

You said

quote:

In what sense are you defining 'evolution'? (1), (2) or (3)?

Mmm...well Neil, let me ask, is there any process which God is forbidden to use, or any process which it beyond God's power to use or set in motion?

If so, as the old saying goes, your God is too small; God could use 1,2 and/or 3 as he so choses - it sort of comes with the peculiarity of being omnipotent.
 


Posted by Karl (# 76) on :
 
I'll be totally clear - short answers rather than multiple choice.

I accept the dating of the origins of the universe to 15-20 billion years ago, give or take.

I accept that the earth is, to the best estimate, 4.6 billion years old.

I accept that current life forms descended from a common ancestral population of self-replicators through the process described as evolution by biologists - descent with modification caused by mutations being subject to natural selection.

Finally, given that nearly every other scientific mystery that people previously ascribed to God working in a supernatural way has turned out not to be so, I suspect strongly that the origin of the first self replicators will also turn out to be explicable in terms of natural processes. Moreover, I have a feeling that an omnipotent God would work that way. It is more impressive to create a universe that has within it the capability of bringing forth life in accordance with His Word, than to have to step in to remedy its shortcomings in this matter. Howard Van Till has some good writings on this - he calls it a gapless universe, IIRC.

As for 'darwinian philosophy' - well, I don't look to science for meaning and purpose, just as I don't try to use musical notation to bake cakes.

Neil Robbie, you still seem to be making the same mistake as ever. You're confusing two things. Science has to proceed non-theistically, otherwise it wouldn't explain how anything happened. It couldn't explain evolution or photosynthesis or how electricity works if the moment it came upon a mystery it said, "God did it." This does not mean that God didn't, or isn't in charge of the ongoing creation. For those like yourself and I, that is an important part of our faith: God is the Creator. But God being the Creator does not tell you how he did it. Evolution, as science, is the how, not the why.

Those people who use evolution to justify atheism, or, as they have in the past, their own political or racial ideologies, are overstepping the bounds of science. Then it becomes quasi-science. Which, frankly, is what so-called "Creation Science" is. It selectively uses facts, distorts and invents others in order to justify a theological position that is not warranted by either Christian history or by the Bible.

Evolution is backed up by so much data that it's as solid a fact as you can get. Use of evolution as a kind of trope in philosophy or politics, even in theology, it is possible to question. I think you have a point there. However, the fact remains that the science is pretty unassailable.
 


Posted by Neil Robbie (# 652) on :
 
Karl and SteveWal, I hope we find that we pretty much agree. Having only read Dawkins, Behe and Johnson for my 'scientific' knowledge, I realise I am not well qualified to discuss such matters. But I do strongly believe that recent challenges to the 'fact' of Darwinism have a strong grounding. Why else would there be so much debate?

I would still like to avoid the use of the word 'evolution', which you both use liberally. My earlier definitions of 'evolution' can perhaps now be more clearly defined in light of what has been posted since.

If we use these three terms, it will help me to understand where you both stand.

Karl wrote (very helpfully):

quote:

I accept that current life forms descended from a common ancestral population of self-replicators through the process described as evolution by biologists - descent with modification caused by mutations being subject to natural selection.


I'm with you on the first two statements of your creed Karl, but would like to redefine the third this way for clarification of my understanding of the current objective scientific work for the support of 'evolution':

I accept that current life forms adapt to their environment and that this adaptation is known as natural selection (micro-evolution).

I accept that in many proven cases, this adaptation has led to separate breeding groups of the same type (I forget the biological terms for breeding groups and same types of animals). (again micro-evolution).

I believe that no conclusive scientific evidence has yet been found for the mechanism of 'natural selection' to produce new forms such as wings or the eye, that there are problems with fossil evidence to support gradual change, and as such 'natural selection' may not have the capability to produce the diversity of living organisms seen today from a single source. (macro-evolution)

I believe that no conclusive scientific evidence has yet been found for the origin of self-replicating organisms. (origin of life).

Is this a fair summary of scientific evidence?

My problem is that Joe Public believes that deism or atheism is strongly supported by Darwinism, because that is what they are taught at school and read in the newspaper (see NABT statement).

Neil

Neil,

The division of evolution into "micro-" and "macro-" is one very few evolutionary biologists would accept, they are both the same thing seen over different time-scales. It is a useful fiction for Creationists who can't deny observed "micro-evolution".

quote:
there are problems with fossil evidence to support gradual change

did anyone say evolution has to be gradual? Infact if the largest evolutionary changes occured during periods of large & rapid environmental change (which would make sense) then there would have been very few intermediary forms, and hence the chance of finding a fossilised "missing link" very small.

The origins of self-replicating molecules on which natural selection could work is, as has been noted, a different subject from evolution. It's difficult to think of what evidence could be found short of recreating those first molecules in the lab (which would be a very difficult experiment).

Alan
 


Posted by Karl (# 76) on :
 
Alan is correct. Nevertheless, I would add that the grossest changes - from fish to amphibian, for example, do happen gradually even when viewed from a geological timescale, where millions of years are the unit of measurement.

A nice collection of such transitionals is at This page.

Conclusive? No, nothing is in science. Strong? You betcha!

As regards the origins of life, my previous post outlines my reasons for believing that there is a naturalistic explanation.

If atheists have been able to imply that evolution supports their position the fault is ours for too often fighting the discoveries of science, from Galileo onwards.

On micro/macro evolution.

Neil, you say that you accept that that variation occurs within species (a l&aacure; spotted moths, the favourite of GCSE biology) but that you are unsure as to how this could have led to the divergence of new species and development of new organs.

At least that is how I interpret what you have said - correct me if I'm wrong.

On new species, if there is variation within a species then there comes a point where there is such a degree of variation that they are no longer considered to be the same species. Although where this line is drawn is rather hard to say. This problem can also been seen with languages, when does a dialect become a separate language? That's a question that raises a lot of issues and has no definitive answer. It depends on many factors.

As to developing new organs by evolution, Dawkins describes (in 'The Blind Watchmaker' I think) how the eye could have developed. In very small stages - a small degree of light sensitivity which gave that creature a small advantage which enabled it to reproduce, a bit more, colour etc. It's hard to comprehend, it takes place over an unimaginable timescale but I can see how that could work. We tend to see everything as black and white (no eye, complex eye) forgetting all the shades of grey in between.

I don't understand why we should be scared of science. God created this world so studying it tells us something about God. Her creativity, exuberance, risk-takingness. Sara Maitland's book 'A big-enough God' is great on this.

Having said that I completely disagree with Dawkins when it comes to Religion. He uses science to back up his philosophy and fails to differentiate between the two. He accuses opponents of 'The argument from incredulity' - I can't believe it so it can't be like that - eg. over the evolution of the eye, but then does the same himself over the existence of God.

The problem is not with Darwinianism per se, but I would agree that the Church (and possibly particularly fundamentalists) have bought into the Rationalists mindset and have tried - unsuccessfully to fight them on their own ground rather than challenging their presuppositions. That is, we've accepted the reduction of 'reality' to that which can be proved by science and by trying to argue 'scientifically' that the world was created in 6 days we have lost the argument before it has begun. By making accepting creationism fundamental to Christianity (which it isn't) we reinforce the idea that we're stuck in the past, that science has replaced religion and that no rational person can believe in God. Forced to make a choice between evolution and creationism people chose evolution as backed up by evidence. Whereas the fundamental point of Genesis 1-3 is the claim that God made the world, and he made it good, it is NOT a scientific account. If you read it, it assumes that the world is flat - something we now know to be untrue, but as a book I was reading pointed out, what the opening chapters teach is not that God made a Flat world but that the (flat) world was made by God.

Quite right. By the 1830's (30 years before Origin of Species) the modern picture of geology was nearly universally accepted, the only difference being they were thinking in terms of millions or tens of millions of years rather than than the 4.6 billion we now know the earth to be. This included the recognition that different aged rocks contained different types of fossils, and that older rocks had fossils that appeared simpler.

I couldn’t resist one last post before heading off for the tropical sun, sand and sea. Can I leave these questions to be pondered?

Please note, everyone, that I am not trying to invoke a literal understanding of Genesis. I have already explained my understanding of the ‘who’ and ‘why’ of Genesis and ‘when’ and ‘how’ of science. Everyone seems to be labeling me as a young-earth creationist, I am not! I find science fascinating and am frustrated that scientists have a prior commitment to everything boiling down to natural systems and never contemplate our Almighty and Sovereign Lord when then evidence suggests that only natural mechanisms exist.

Karl already said that God made the Laws of physics, chemistry and biology but that God can intervene as and when God feels like it. So why could God not intervene to kick start life? Why could God not intervene in genetics to form humans? Why must science have a prior commitment to philosophical naturalism?

To illustrate the point, can someone please give me the scientific facts of how the following came to be? I don’t expect theories or guesses or hypotheses, which dominate all the previous answers. I am looking for solid physical, chemical, scientific fact. No extrapolation, no mathematical models or observations of how they work. I would like to know the chemical step-by-step development of the following bio-mechanical mechanisms.


  1. How did ‘self-replicators’ appear in the prebiotic soup and develop step-by-step?
  2. How did the mammalian blood clotting mechanism develop step-by-step?
  3. How did the photosynthetic reaction center develop step-by-step?
  4. How did cholesterol biosynthesis begin or develop step-by-step?
  5. How did intermolecular transport start or develop step-by-step?
  6. How did retinal become involved in vision, step-by-step?
  7. How did phosphoprotein signaling proteins pathways develop step-by-step?

There are two more questions:

How is genetic information formed? As I understand it, our genes are like a pack of 52 playing cards which get shuffled about from generation to generation. What mechanism exists to make 53 playing cards? Has the formation of extra genetic information been observed?

My last question is perhaps the most brain-stretching. If DNA is the code for which living features are formed, and scientists talk about genetic blue-print (engineering drawing in modern language), or genetic language, how did it come into existence, step-by-step?

Information is what we read in the pages of a book or in this thread. DNA proteins and amino acids are to DNA what paper is to a book or semi-conductors are to a computer. But information is the words themselves on the paper and on the computer screen. Information is different from matter.

Each human cell contains the same amount of information (letters and words not paper) as all 30 volumes of Encyclopedia Britannica and there are 300 million million cells in the body. How did this information come into existence?

These questions fascinate me. Does anyone know the answer? I am not pointing to young earth or creationism in that sense, I just want to know if (neo)Darwinian or (neo-neo Darwinian – chance, random events) theory can explain all these things.

Neil


PS See you Monday
 


Posted by Karl (# 76) on :
 
Neil, you're asking the impossible. Perhaps one of the most frustrating characteristics of evolution's detractors is that they castigate scientists from drawing what are in fact well supported, solid inferences, then require them to make far less well supported ones.

To give the exact sequence of developmental steps in each of those pathways is impossible, because we have no way of knowing the cascade reaction sequence in the trilobyte. Do you know how difficult it is to ascertain these sequences in living animals? The procedures would be impossible in a fossil of the hard parts alone! The answers you seek can never be found. Moreover, "theories or guesses or hypotheses" are all science has! The orbit of the earth is only a theory. As is atomic theory, relativity theory, et al. Why is theory good enough in these fields but not in origins sciences? The irony of your question is that the pathways you refer to are theoretical, from inspired guesswork and testable hypothesis. You might as well claim you don't think there's good evidence for them!

I would recommened, by the by, again, that you read Kenneth Miller's Finding Darwin's God. He devotes some time to Behe and you may find it illuminating.

This one I can answer:

quote:
What mechanism exists to make 53 playing cards?

Gene duplication

quote:
Has the formation of extra genetic information been observed?

Yes

As regards the origins of genetic material, that is not my field but I will endeavour to find out for you.

quote:

It doesn't. It has a prior commitment to methodological naturalism.

quote:
So why could God not intervene to kick start life? Why could God not intervene in genetics to form humans?

He could have done. But that is not a scientific hypothesis. Perhaps He did. You are free to accept that. Personally, I believe that God does all His general work through natural forces, for reasons outlined in earlier posts.

Karl also drew the distinction between philosophical and methodological naturalism. The pursuit of science is methodological. Each scientist's beliefs about the resulting knowledge pertain to the philosophical. We only know of the philosophy of a few highly visible scientists like Dawkins, etc. You seem to be lumping all scientists into this overarching philosophy when only the results of their methodology is known.

Kenneth R. Miller in the early chapters of his book, "Finding Darwin's God," has pondered the very same issue. I've only just started the book but it looks thought-provoking.

As for scientific research itself, what would you change? How would you draw the line for research between natural process that we don't yet understand and processes that were a direct intervention by God? Who will say (and who do you trust to say), "We understand this. We don't yet understand that but research will clear up the confusion. And God clearly was involved in this step so we don't need to spend research time or money on it."

How will we know that a particular unkown is a direct work of God? Will we be able to formulate a working hypothesis and will God be amenable to testing? Will we allow the Church to say "This was a result of divine intervention. No research is to be done or published in this area." Galileo had a similar experience. Or will the committees who decide on grant funding make those decisions?

Science is the study of natural systems, the study of other systems is the realm of philosophy and theology. Now I welcome scientists contributing to these fields, but far too often it is more a naive blundering about in something they don't actually understand expecting (and often getting) a hearing because of their scientific authority. A good scientific reputation can not give someone authority outside their own field of study; I'm more than happy to accept Dawkins ideas about the science of evolution, but he's no more an authority in philosphy than he is in quantum physics until philosphers recognise the value in what he contributes to their field of study.

Many scientists do have a religious faith (including an atheistic faith), and a contribution to make to philosophy and theology. But it is a mistake to hold the views of scientists as any more informed in these fields than the views of any other amateur philosopher or theologian.

I don't think any Christian would deny that God could have intervened to kick start life or direct evolution. The questions are did he in fact intervene, and would he intervene? Now until science conclusively proves there are or aren't any steps in the start of life or evolution that correspond to the work of God the first of these is unanswerable. But we can reasonably speculate whether it is in the character of God to intervene in his creation in such a manner.

My personal opinion is that such intervention is unlikely. I've noticed that God does tend to work through natural processes in a manner that is only discernable by the eye of faith. It is by faith I believe that God created the heavens and the earth, and so when I look at the stars or study the processes within the atom I believe I am watching God at work. If God works through and within natural processes now, what reason have I to expect him to have done something different in the past?

There are still, however, very good scientific materialistic explanations of those same things in which I see God at work which don't rely on the hand of God directing things. As Karl has said on several occasions, science is methodologically materialistic. There is no other way for science to work. If we say of a phenomena that "God is at work here, so there won't be a materialistic explanation" then there is no further question or investigation possible. If, on the other hand, we look at the same phenomena and say "something is happening here I don't understand" then there are questions to ask and things to be investigated; science thrives on answering difficult questions and explaining the unexplained.

Sorry for a fairly long post. Neil, I hope you enjoy your long weekend in a tropical paradise. I'm not jealous, honest

I would like to point out that natural selection is not evolution. Natural selection (that species develop different attributes) is an established and observable fact. Evolution on the other hand suggests, without a single shred of evidence, that one species turns into another.

I know it can be a bit exhausting to have loads of books recommended to you but can I suggest a good one to start on this question would be The Wisdom of the Genes: new pathways in evolution by Christopher Wills (1989)Basic Books/Oxford university press paperback).

Wills discusses ways in which natural selection can be expected to favour organisms that have genomes (their genetic material) which have features that make them able to evolve more rapidly.

quote:
Each human cell contains the same amount of information (letters and words not paper) as all 30 volumes of Encyclopedia Britannica and there are 300 million million cells in the body. How did this information come into existence?

To quote Wills:

quote:
Each species [including humans] no matter how simple or complex has a history of three and a half billion years ... the ones that are left are, for the most part, a superbly fit set of survivors.

So bags of time for variation plus natural selection to accumulate all that information. (If you were to count off those three and a half billion years aloud at the rate of one a second at it would take you, with 8 hours sleep a day, one hundred and sixty five years to do so.)

Wills also talks about staggering variety amongst the eight hundred different species of fruit flies on the Hawaiian islands which have all evolved from very few or possibly even one original(fertilised female)fly to fill the many niches in the ecology that are available because of the absence of most other types of insect. A far better example than the good old Peppered Moth.

When i left university in 1977 after a biology degree the evidence for evolution overwhelmed my fundamentalistic leanings. In the 24 years since the evidence has just got more and more compelling (from geology, from molecular biology, developmental genetics, paleontology, and so on, many independent areas of research (thus minimising circular reasoning)).

Actually natural selection is the mechanism by which variations within a species that provide an advantage for survival and reproduction are preferentially transmitted to later generations.

Evolution is simply the observation that naturally selected variations result in changes in physiology and/or behaviour over time. While it may be reasonable to consider slight varients to be the same species, larger variation results in an inability to inter-breed naturally and so a new species evolves. Any evidence for evolution within species over time is also evidence for evolution from one species to another, for it is the sme process.

I come to the Ship to get away from creationist nonsense like this. Not a shred of evidence indeed - rhetorical baldersash. If this thread were in Hell I could tell you what I really think of that statement.

But since we're in Purgatory, a few of links will have to do:

29 Evidences of Macroevolution

Observed instances of speciation

Transitional Vertebrate Fossils

Enough evidence to be going on with for now?

My sympathies to Karl on his frustration with "creationist nonsense".

My overwhelming feeling with Creationists is similar to that I have with some of the people who pontificate over end time prophecies (especially to the point of not worrying about pollution etc because it's all going to be over next week when the final whistle gets blown).

As JB Phillips (I think) put it "Your God is too small".
 


Posted by Neil Robbie (# 652) on :
 
My wife and I arrived back last night from our tropical weekend having sailed a Dart 18' (sports catamaran) accompanied for a few minutes by half a dozen dolphins. It was the most spectacular sailing of my life!

I am sad that the thread is degenerating into a 'evolutionists' verses 'fundamentalist creationist' ding dong. Can we try an move beyond this level of discussion to New Labour territory, the 'third way'? For the benefit of all, evolutionists and creationists, here's a bit of an example of evolution from my snorkelling at the weekend.

As I emerged from the sea, snorkel and fins and all, I saw on the rocks what I think must be 'lung fish'. The biggest of these were about 2 inches long, eyes on top of their head, basking in the sun on the rocks. When I got close, they shot off across the surface of the water, like 'skimming' or 'skiffing' stones, or like swimmers who hate getting their hair wet. They used their lateral fins to move over the rocks and the surface of the water.

I went looking for them again on my last day. While snorkeling in the shallows, I saw similar fish, underwater, again using their lateral fins to move over the surface of the rocks. These fish were about the same size and shape (eyes were not as pronounced) as the other fish on the rocks above the water.

It doesn’t take much imagination to link the two and say that the 'lung' fish had 'evolved' from the similar looking fish underwater. A creationist might argue that that's just the way God made them.

But I would like to take the middle way and say whilst 'evolution' is evident, 'evolution' is not evident. What do I mean?

I do not have any problem with the theory the fish could be related and that one, by the scientific fact of natural selection, has developed the ability to live out of water. I'd be interested to know if any zoologists know of this particular species of fish and the way that they breathe. It appeared to me that they took great gulps of water every time the water sloshed over them, so perhaps their gills are internalised. So, step-by-step, one fish might have crawled out of the sea and now lives only surrounded by air, with the occasional soaking from the sea.

It's like the example Glenn gave regarding the fruit flies on Hawaii.

I have no problem with this theory as micro-evolution explaining this speciation. However, anything beyond the observed micro-evolution examples described above is speculation. To say that one day these fish will develop legs and lungs and hair and warm blood - (macro)evolution - has no current scientific basis, especially in the fossil record. The fish are still fish and the fruit flies are still fruit flies, and the peppered moths are still peppered moths. So I am an evolutionists, in the sense of living creatures develping distinct features, but I am not an evolutionist if someone tells me that the 'lung fish' will one day turn into a rabbit.

And, as for their origin from pre-biotic soup…

I think I need a new post

Neil
 


Posted by Neil Robbie (# 652) on :
 
Glenn, you show that there has been 'bags of time', for life to emerge from the pre-biotic soup. I agree that the unibverse is 15-20 billion years old (revised from my previous 12 billion).

But, have you read Michael Behe's book, 'Dawrin's Black Box'? He points out that it doesn't matter how much time has been available, bio-chemists must now find a series of chemical reactions which could have produced life with the available chemical material. Chemists already have a pretty good idea of the material which was around before life began. (BTW, I will purchase Kenneth Miller's book 'Finding Darwin's God', as a number of people have recommended…and I assume you have all read Behe's book (though sometimes I wonder), if not I commend it to you as Miller's criticism will no doubt focus on selected parts and not the whole - and read 'Darwin on Trial' too).

Karl, we know that the theories of the universe have been measured, if not we could not predict the movement of the planets and we could not send space probes to Jupiter. These measurements give us great confidence in the theories of relativity and theoretical orbit of the earth. In the closing chapters of 'Darwin's Black Box, Michael Behe points out the efforts made last century to escape the 'big bang' theory as Hubble's measurements began to show an expanding universe with a beginning in time, because it supported a Judeo-Christian (not young earth) understanding of the universe. Are (neo)Darwinists doing the same today?

We can not compare the physical theories of the universe with the bio-chemical theories of the origin of life and macro-evolution. Physical measurement supports physics, but bio-chemical models can not be formed to match the theories. If we know which chemicals exist in the basic building blocks of life, why has no scientist been able to provide us with a chain of chemical reactions which could have led to the development of these basic building blocks?

I notice that no-one posted responses on the issue of information as separate from matter Is this something that no-one wants to talk about? If you have read Philip Johnson's book 'The Wedge of Truth', you'll know what I'm talking about.

With no chemical support for origin of life theories, I think we must now return to the 'how' question of science? willyburger said:

How would you draw the line for research between natural process that we don't yet understand and processes that were the direct intervention by God?

Willyburger, your explanation of methodological naturalism has to be broken down into two 'how' questions to be able to answer this question:

I used to own a 1984 Vauxhall Cavalier (no comments please). I used to dismantle the brakes, change the timing belt and think I knew pretty well how it worked. The methodologicalism of biology is just the same…working out 'how' it all works.

My tinkering with the car did not invoke the question 'I wonder who designed this car?' Science doesn’t need to answer that question of biology, unless you are a philosophical naturalist opposed to the idea of a designer or a creationist in favour of finding evidence of a creator.

Surely the job of science is to focus on the pursuit of the how everything works (methodologicalism) question.

Research of this sort is deserving of public and private funding. How else will medicine and our understanding of the physical world advance? This is real science with a worthwhile product.

But surely, only philosophical naturalists will pursue the 'how did it come into existence without invoking the supernatural' question. Let philosophical naturalists fund this research, but don't use public money.

In the USA, 90% of the population believes that 'God' had some part to play in creation. Why should Joe Public fund the research of philosophical naturalists who in their research pursue the evidence of a purposeless, random, material universe?

It is by confusing the two 'how' questions that science and scientists are able to misuse the funds available.

Keep funding to methodologicalism, and use the money to find out how life works for the benefit of medicine. I hope you share this view that we can not support the squandering public money on the private pursuit of philosophical justification.

The fish are still fish and the fruit flies are still fruit flies, and the peppered moths are still peppered moths. So I am an evolutionists, in the sense of living creatures develping distinct features, but I am not an evolutionist if someone tells me that the 'lung fish' will one day turn into a rabbit.

I still find it surprising that the fiction of "micro" and "macro" evolution is still so common; it is an invention of Young Earth Creationist (as I recall to support the idea that the Ark held a pair of each "kind" to repopulate the earth after the Flood from which each species within that kind evolved, because otherwise the Ark would have been far too small. Which incidently requires a rate of evolution far greater than that required by the scientific view).

Why is it so hard to grasp the idea that if a fish can breathe out of water by having a "lung" full of water that over sufficient time that water filled lung couldn't become a mucus filled lung that doesn't require constant refilling with oxygenated water? Evolution works in small steps, the lung fish you observed out of water are a small step from similar fish still living in the water, and another species which has developed a way of reoxygenating the water held in its lung from the air so can spend longer between a fresh intake of water is another small step further on. Whether that particular species will evolve further depends on circumstances; it is adapted to its current environment, and so will presumably only evolve further if the environment changes or a new environmental niche opens up which isn't occupied by a "fitter" species.

BTW, as far evolution of legs is concerned. The fossil evidence, or at least the way it's interpreted, is that legs evolved in fully aquatic fish first to allow ease of movement among thick water vegetation. Presumably such vegetation being on the land/water margin the migration to land from there would be a relatively small step to search for new food sources or to avoid predators.

And, as for their origin from pre-biotic soup…

As noted, the origins of the earliest life forms are beyond the realms of evolutionary biology, which requires life to exist, and rather biochemistry.

Neil Robbie -

I think you're still missing the point about methodological naturalism.

It does not exclude God from the processes in order to justify a "Godless" world. It excludes a "supernatural" event because to include it would be to prevent rather than aid discovery of the processes of evolution.

I see no contradiction with evolution in my own faith: God has created and is creating the world through natural processes. And if someone discovers the exact formula for creating life biochemically, that would not make any difference to my faith. It would still mean that God is working in the world: but through natural processes, not some form of David Copperfield magic wand system: "Shazzam! Look, life!" In fact, the idea that God sometimes intervenes to chivvy the process along, assumes that for the most part He keeps away, then comes in, points His finger and Bang! Dinosaurs become birds or something. I've always believed that God was involved in the process right from the beginning, in the natural processes themselves, not just sitting on some mountain throwing magic thunderbolts every now and then.

Belief in a creating God is pretty essential to Christian faith: but that is perfectly consistent with methodological naturalism, in whatever form you put it. "How" questions are not theological questions.

I think you're looking for some kind of certainty that it is God, not just an accident, but I'm afraid that scinece can't, and shouldn't, provide it. There will always be the possibility that we are all the product of a series of "accidents", and that we are all mere products of the natural world. There is also the other possibility: that we were and are created by a loving God who wants a relationship with us.

We can't look to science to answer that dilemma, though; we have to look to faith, and maybe to those experiences of the numinous that sustain us. Faith is not about certainty; it's about trust.

Those fish sound like mudskippers to me. Interesting fish. But your illustration adds up to no more than argument from incredulity.

The big problem with the micro-/macro- division is that anything you show the creationist can be dismissed as being only 'micro-'. But how many micros add up to a macro?

And why do giraffes and cows have the same viral DNA insertions in the same place in their genomes if they do not share a common ancestor? Why does cytochrome C similarity data match the phylogeny derived from the fossil record so well, if not from common descent with modification? Methinks that denying common descent poses more questions than it answers, and I'm unimpressed with 'goddiditthatway' answers I've had in the past.

I don't know why folk are banging on about Behe - he accepts common descent - fish to rabbits - and is so damned near to theistic evolution it's hard to slide a card in the crack.

And how many times do we have to reiterate that science is not philosophically naturalistic, but only methodologically so? Science does not say that natural explanations are all that exist, just that they are all it is concerned with.

I think I can answer this point completely as it is in the area of things I think I know something about.

The question of "information" comes up in this kind of discussion because the word "entropy" is used both in Thermodynamics and in Information Theory. However it doesn't mean the same thing in each case, although there are a few parallels.

In Thermodynamics it indeed represents the "degree of disorder". On the "macro" scale things all at different temperatures are said to have less entropy than the same group of things at some averaged-out temperature. On the "micro" scale, molecules of things move around fast if they're hot and slower if they're cold. As heat flows they get all mixed up and disordered in the sense that where they reach the same temperature, the hot fast-moving molecules get all mixed up with the slow-moving ones, so to speak.

Entropy in the physical sense is a measurable physical quantity with units - Joules/degree Kelvin. The second law says that in a closed system it is constantly increasing - in other words put a collection of things of different temperatures together with nothing allowed in or out and they'll assume an average temperature. The important point is the words "closed system" and with the sun spewing oodles of energy in our direction the system of the biosphere isn't closed.

Now in information theory entropy means the degree of unreliability or uncertainty of a set of data. You might decide that you believe 90% of what Karl says and only 75% of what I say. This would mean that what comes out of my mouth has a higher information theoretic entropy than what emerges from Karls in your opinion. It doesn't refer to "disorder" at all in the sense of being mixed up.

Entropy in Information Theory is a unitless amount. The second law of Thermodynamics has no bearing on it, and no one has devised a relationship between the two quantities both called entropy. I don't think there is one.

Unfortunately a lot of Creationists have latched onto the word Entropy and use the two meanings interchangeably. The result is probably an increase in both kinds of entropy. I'm sure Mr Shannon (pioneer of Information Theory) whould have used a different word if he'd known how much it was going to be abused.

Hope that helps.

Okay, now you're finally talking about something I can understand!

I think you're sadly mistaken if you think scientists investigate the detailed workings of biology in order to justify their philosophical stance. If I were one of them, I'd be offended at the implication of intellectual dishonesty and dealing in bad faith in your post.

I'm appalled at the suggestion that the allocation of public money for scientific research should be influenced by what "Joe Public" thinks. The average American also thinks flying is more dangerous than driving, is more innumerate than I am (scary fact), and reads his horoscope in the morning to find out if it's going to be a good day.

One thing I should have added in my previous post is that Information Theoretic entropy can be reduced. To take the example of what I say being 75% reliable, you could carefully verify my statements and confirm them or correct them where they were wrong and end up with something you were up to 100% confident in. You would then have reduced the entropy.

In summary the whole issue of "information" raised by creationists is a huge red herring in my view.

Willyburger, your explanation of methodological naturalism has to be broken down into two 'how' questions to be able to answer this question:

[LIST]

  • How do biological mechanisms work (methodologicalism)?

  • How did biological mechanisms come into existence without invoking the supernatural (naturalism)?
    /LIST]
    I used to own a 1984 Vauxhall Cavalier (no comments please). I used to dismantle the brakes, change the timing belt and think I knew pretty well how it worked. The methodologicalism of biology is just the same…working out 'how' it all works.

    My tinkering with the car did not invoke the question 'I wonder who designed this car?' Science doesn’t need to answer that question of biology, unless you are a philosophical naturalist opposed to the idea of a designer or a creationist in favour of finding evidence of a creator.

    The two questions, "How did biological mechanisms come into existence without invoking the supernatural?" and "I wonder who designed this car?" are not equivalent. The first is still a 'how.' The second is a 'who.' Instead, in the process of taking the car apart, are they not valid questions to ask, 'how was the car designed?' and 'how was it assembled?' in the process of understanding how it works?

    And shouldn't you be as suspicious of a Creationist Scientist 'in favour of finding evidence of a creator' as you are of the philosophical naturalist who is opposed to the idea of a designer?

    Surely the job of science is to focus on the pursuit of the how everything works (methodologicalism) question.

    I have to question that assumption. I propose that the job of science is knowledge, wherever it may be.

    Both of your questions at the top of this post are 'how' questions, yet you wish only to allow one of them to be asked. It seems to me that you are trying to maintain belief in a creator by preventing the other question from being asked at all. (Did that break any commandments?)

    Research of this sort is deserving of public and private funding. How else will medicine and our understanding of the physical world advance? This is real science with a worthwhile product.

    'Science' is the pursuit of knowledge for its own sake. The 'worthwhile product' is merely technology. Whether that technology (cloning, nuclear weapons) should be used lies in the realm of ethics. Why things are the way they are and Who, if anyone, is responsible for our existence, are in the realms of philosophy and theology.

    But surely, only philosophical naturalists will pursue the 'how did it come into existence without invoking the supernatural' question.

    I'm afraid I have to question that assumption as well. There are plenty of theists who see no conflict between studying the mechanisms of evolution and their faith. Many see this world with the mechanisms *predesigned* to play out in a natural way. In the end, your argument opposes theistic evolutionists as well as philosophical naturalists.

    In the USA, 90% of the population believes that 'God' had some part to play in creation.

    What my esteemed countrymen know about science in general leaves much to be desired. After all, surveys show that less than half of them know that the Earth revolves around the Sun or that the Sun is a star. (CNN)

    But in all seriousness, don't theistic evolutionists by definition believe that God has/had some part to play in creation?

    Why should Joe Public fund the research of philosophical naturalists who in their research pursue the evidence of a purposeless, random, material universe?

    Im sorry, but that begs the question. Most researchers go where the science takes them. How they answer the 'who' and 'why' questions are best left to their own conscience. The few outspoken philisophical naturalists like Dawkins are already publishing through the private sector, are they not?

    I hope you share this view that we can not support the squandering public money on the private pursuit of philosophical justification.

    'Fraid not. I think that any increase in knowledge in general is a good thing. Would theistic evolutionists think the money is misused or squandered? You appear to keep drawing a theist/atheist line in the sand over the issue of evolution.

    God exists; God doesn't exist. Research in evolution will never prove one over the other.

    I share your sentiment that this thread not degenerate into a creationist vs. evolutionist slugfest.

    I am very sorry, Ruth, for upsetting you with my last post. I'll try to be more careful when I write.

    willyburger, you concluded the debate on scientific evidence nicely when you implied that we'll never know God by looking at the results of research into life.

    Speculating on this matter from the perspective of the cross, perhaps God doesn't want us to know about God from science. If our faith depends on the cross alone (simply to the cross I cling), it wouldn't do for us to say "I cling to the cross and the evidence of God in science".

    Ruth & willyb, I am interested in the straw men you invented when referring to 'Joe Public' America. Apart from horoscope believing, driving is safer than flying believing bods and the unscientific young earth creationists, there are a number of people, scientists among them, who are rational and can still smell a rat.

    I lived in Cambridge for a number of years. Some friends at church were fellows at various colleges. Among them were theoretical physicists and chemists. They each had a firm faith in Christ and an 'old earth' understanding of the universe.

    When asked about their faith in Christ and their science, they would say that the more they knew about the way things worked, the more they were amazed at the way God had designed it - a simple observation of scientific fact in the light of faith in Christ.

    We often commented at that time on the fact that there were very few Christian biologists. Why was that, when there were so many Christian physicists and chemists?

    Is it because biologists are committed to methodological naturalism as the basis for research? Back to the Vauxhall Cavalier. I disagree with you willyburger about the 'who' question of biology. Asking 'how could this car work without invoking the supernatural' is the positive way of saying 'there is no designer, so how can I prove that it isn't designed (the blind watchmaker - there is no 'who' only an apparent 'who')?'

    I propose that there are few Christian biologists because of the effect of Darwinian philosophy which has prevented biologists being wowed by the way God has designed life. If a biologist dares to say 'wow, look at the way God designed this', it is contrary to the philosophical naturalism of Darwinism, just look at the theistic evolutionists' response to Michael Behe et al.

    Why don't theists spot this? Is it because we are so immersed in Darwinian philosophy that we can't see the woods for the trees, or rather we can't see the designer for the bio-chemical mechanisms?

    What do you suggest? That biologists should abandon the natural conclusion of their evidence - evolution - in favour of ID, not because it is true, but because of the 'wow' factor.

    No.

    I believe in intelligent design from a philosophical viewpoint. I do not, however, expect to find scientific evidence of design. It is seen with the eye of faith.

    If atheism has dominated biology, this is because we have allowed it to do so, and it has been through disavowing mainstream biology, not by embracing it, that Christianity has done so.

    Our witness must be that God can create through the contingency of the evolutionary process, not that God is an alternative hypothesis.

    Neil Robbie:

    That is certainly possible. Science and theology have different goals. You may find that they complement each other if each is left to their respective business without the insistence that one dictate terms to the other.

Asking 'how could this car work without invoking the supernatural' is the positive way of saying 'there is no designer, so how can I prove that it isn't designed (the blind watchmaker - there is no 'who' only an apparent 'who')?'

    Then we must disagree. Formal logic (which was a long time ago for me) demonstrates that you can't prove a negative. You will never prove by evidence the universal non-existence of anything, especially God. You will also never prove the non-existence of the metaphysical (God) through empirical (physical) means.

    You are also drawing a false conclusion. Just because one is convinced that the world developed and runs by natural means doesn't necessarily mean that one believes that there is no design, which necessitates a designer.

    Did your physicist friends express their belief and wonder among fellow believers? Or did they also consciously shape their research because of it and write it into their published research? There's a proper context for everything.

    BTW, are you accusing theistic evolutionists of philosophical naturalism because they disagree with Behe? Is his theory so sacrosanct that you can paint with so broad a brush?

    Neil Robbie:
    Why don't theists spot this? Is it because we are so immersed in Darwinian philosophy that we can't see the woods for the trees, or rather we can't see the designer for the bio-chemical mechanisms?

    Or maybe they have given it much thought and disagree with those conclusions....

    Most Americans don't know thing one about basic science. They think their stomachs actually shrink if they eat less food and grow if they eat more. They don't know why bread dough rises. They don't know why soap and water gets clothes cleaner than just water.

    This is not a straw man. The scientific education of most Americans is woefully inadequate, and therefore what most Americans think or believe is a poor basis for deciding how to spend money on scientific research.

    I don't see that your not knowing Christian biologists at Cambridge is evidence that biology as a science is somehow leading people away from God. Hardly a statistically significant sample!

    There's already been plenty of discussion about whether state-of-the-art evolution theory can be properly characterized as Darwinian. And I don't see why you continue to insist that biologists have a Darwinian philosophy. And when I was reading Stephen Jay Gould, I thought he seemed pretty wowed by the mechanisms he was investigating.

    SteveWal, thank you for being so clear in defending your on position on methodological naturalism and Christian faith, I can see the point of your argument. You said
    quote:
    "how" questions are not theological questions"
    . Your personal conviction is not what I'm trying to highlight or attack. It is the public perception of science giving the 'how without God' answer which I am concerned about.

    RuthW, I'm very glad you're talking straw men. I wrote this post offline and have just read yours, which ties in nicely to what I wrote.

    The straw men which both SteveWaland you have drawn our attention to, the unscientific horoscope believing, 'driving is safer than flying', tummies shrinking when you don't eat Joe Public and the unscientific young earth creationists are, IMHO, not what make up the majority of the general public.

    I don't know what kind of company you keep, but the Joe Public I know are rational, well educated, professionals who will not consider faith in Christ because their minds have been filled with philosophical naturalism from primary 6 (11 years old) at school. The biology lessons are supported by David Attenbourgh's 'Life on Earth' and TV programs of the sort, and the mainstream media.

    What is taught in the classroom as biology, and the theories speculated about in popular TV programs do not reflect the ongoing scientific (not theistic) concerns about fossil records, irreducibility or the creation of information or so on, much of which we have discussed on this thread.

    Our education system does not train the mind to think about the scientific discoveries in an open light. Darwinian theory (and the philosophy which accompany it) are taught as dogmatic 'fact'.

    How do we want our children to grow up? Being taught dogma or being encouraged to think laterally and openly about science?

    I am not a young earth creationist, but I want my children to be able to think for themselves, not to regurgitate Darwinian dogma.

    I also want my friends and family to share in the love of Christ, and I know that Darwinian philosophy is a deeply ingrained barrier to that goal.

    What matters to me, as a Christian, is honesty. Scientists are free to chase whichever philosophical goal they like, they can conclude what they like from the findings of science, but they must be honest about the current evidence. Joe Public deserves to be told the truth.

    And the truth is, as Karl said

    quote:
    to give the exact sequence of developmental steps in each of those pathways is impossible
    . That's the truthful, honest answer. We don't know about 'how' intermolecular transport systems developed step-by-step. We don’t know about 'how' information as distinct to matter came to be. We don't know 'how' self-replicators first developed in the prebiotic soup.

    The biology classroom in the US is being defended by 'civil liberties' groups from 'creationists', the NABT do not want Darwinism questioned. But history has shown, as it did for the church in the sixteenth century, that humans will not stand for dogma. If Darwinism, and all its derivatives, are not allowed to be subject to criticism, the tide of public opinion will go against it and people will leave the cult of Darwinism in droves, searching for the honest answer.

    Science should say to Joe Public, now, that 'we don't know 'how' it came into exisitence'. If science stands by the statement that 'we are sure we can prove what we believe', the battle is already lost. The problem is, the public still see only the latter statement.

    I think in this light, I should rename this thread - 'Questioning Darwinism - a civil liberty' Then, back to the original question, how will our theology, or application of scripture change in light of the questioning of Darwinism? Perhaps we need to wait until the day!

    You're entitled to question 'Darwinism', and much ink has been spilt doing so. We are giving our reasons why evolution is science, not philosophy, and why it should be the model taught in school - because, like all scientific models, from the earth being a sphere upwards, it is the best supported model we have. Nothing is proved in science.

    If folk think that evolutionary science stands in contrast to faith, then it is because the creationists have told them so. It is our task to point out that it is not so. There is an unholy alliance between creationists and atheists at work here, spreading this lie. Whoever would have seen Dawkins and Hovind in bed together?

    I desperately don't want to start a fight here or sound put out (all though I am a bit) but I did try very hard to explain why discussion of "information" is a red herring and one fished for by Young Earth Creationists.

    You say that you're not one and yet you pick up arguments and recommend books written by them (for example Philip Johnson, a law professor).

    I don't actually see religion in conflict with science. As someone else put it, which is more powerful a tiger or a great white shark? The answer depends on the domain.

    Personally I think the conflict is really between religion and science on the one side and people who couldn't care less about anything on the other.

    I don't think "Joe Public" in the U.K. is overall much different to the U.S. when it comes to scientific knowledge, but that's bye-the-bye.

    Like Neil, I've heard some professional, degree-level educated folks in the U.K. reject Christianity because of their (mis-) understanding of Science, but my view is woolly and dumb thinking (and whatever one's religious views, scientifically speaking it is dumb thinking) are problems for Christianity, Hinduism, the Conservative Party (U.K.), business leaders, union leaders, etc. etc.

    I think that the problem comes from many people, starting with contemporaries of Darwin and even earlier (let's be honest here - there's a lot of history to want to forget) with Gallileo, that Christianity is at odds with Science. In the Church we've got a lot of ground to make up to be able to get across that having half a brain and questioning the world is not incompatible with Christianity. Whether we like it or not, high-placed folks in the Church have implicitly and explicitly been sending that message out for years.

    I could blow off about the problems of getting most clergy in the CoE to take science seriously - but that's a personal diatribe I'll do off line!

    So, unlike you Neil, my view is it's our problem, not a Darwin problem. People like Dawkins or (worse) Don Cuppitt confuse the two disciplines, or perhaps more accurately, the three disciplines - the third being philosophy - in an awfully misleading manner to themselves and others. That doesn't mean we should reject the theories of evolution - that's just putting our head in a different patch of sand.

    Neil,
    If there are limits to naturalistic explanation of life and the universe, if there is no explanation of how life came out of the pre-biotic soup, then the only way we are going to know that is by intensive research into trying to find natural mechanisms whereby these things might happen and failing.

    If you are saying that you know the limits to biological investigation in advance (by divine revelation?) and that on that basis you wish to prevent research then you are back with the church against Galileo!

    If there are limits then they will eventually be found, and even then the duty of scientists will be to try again to see if they may have missed something.

    And none of this excludes the world being God's world, brought about by him by astonishing and discoverable mechanisms.

    If you will insist that theism is only possible if we declare now that science can't explain origins then we will never know if theism is possible because none of us will live to see science reach its limits!

    If you believe that Behe is right to say that certain biochemical systems are irreducibly complex and cannot be evolved but must therefore be designed, then your best method of supporting Behe is to encourage research to try and prove him wrong. If they fail to do so then his theory looks more plausible. If on the other hand you wish to prohibit such research you are declaring yourself beyond science and beyond the challenge of your peers.

    quote:
    But surely, only philosophical naturalists will pursue the 'how did it come into existence without invoking the supernatural' question.

    Are you saying that a Christian biologist who wishes to try and find out whether mechanisms existed whereby life could naturally arise from the pre-biotic soup is denying God? Nonsense! She/He is just trying to find out HOW it might have happened. This still leaves open the question of the whole significance and purpose of the universe.

    I don't know what kind of company you keep, but the Joe Public I know are rational, well educated, professionals who will not consider faith in Christ because their minds have been filled with philosophical naturalism from primary 6 (11 years old) at school. The biology lessons are supported by David Attenbourgh's 'Life on Earth' and TV programs of the sort, and the mainstream media.


    The general public as a rule are not well-educated professionals. And most well-educated professionals are actually quite ignorant of basic science. I am well-educated and I used to be a professional (English professor). My colleagues in the school of humanities were bright people, yes, but most of them knew very little about science. Like me, they took the undergraduate science courses they needed to fulfill their general ed requirements and then promptly forgot most of what they had learned. I'd bet the rent that at least half of them couldn't explain how electricity works. I sure never learned that in school, and only know now because I got my brother the rocket scientist to explain it to me.

    I'm not saying most people are bone dumb (although on not so good days I tend to think that) -- I'm saying most people don't know much about science (and don't care, either).

    I sincerely doubt that most well-educated professionals aren't interested in Christ because their minds are full of philosophical naturalism. I suspect it's because they have not seen how Christ is relevant to their lives. Well-educated professionals are among the most difficult people to evangelize, IMO, unless you catch them at a crisis point. After all, they usually have satisfying careers that pay them relatively well, some degree of prestige, stimulating co-workers, and unless their private lives are disastrous, it's hard to show them that anything could be missing or awry.

    It's not philosophical naturalism that's keeping them away from God -- it's that they see nothing wrong with their lives.

    Thank you everyone for your patience with me. I realise that I have not read widely enough to understand the complex relationships between science, philosophy and Christianity. I'm beginning to see things more clearly now, but forgive me if I still show signs of ignorance.

    Glenn, you said:

    If there are limits then they will eventually be found, and even then the duty of scientists will be to try again to see if they may have missed something.


    I realise that my posts have given the impression that I may have a prior commitment to 'divine revelation', but that is not what I meant. I agree with you Glenn that we must seek for the truth and that only thorough scientific research can unveil that truth. I was led by reading 'Darwin's Black Box' that bio-chemists have dug their way down into the finite limits of biological mechanisms and have already concluded that they are designed. According to Behe there is a total lack of serious explanations to the step-by-step development of the irreducible systems he highlights. The book was written in 1998 and I know there are responses to the challenges Behe put before the scientific community, but what I have read on the internet recently does not give rise to any confidence that irreducibility is a problem which will be easily solved.

    Which brings me to what Karl wrote:

    quote:
    We are giving our reasons why evolution is science, not philosophy, and why it should be the model taught in school - because, like all scientific models, from the earth being a sphere upwards, it is the best supported model we have.

    I can not argue with your point about the best supported model, Karl. But, if the truth is to be taught, school children should be presented with the facts, and the facts include the current problems outlined above.

    John, I am sorry for not responding to your interesting post on information theory. To be honest, I've re-read it and don’t quite understand it. I am a Civil Engineer and have a good grounding in all three sciences (Physics to 2nd year undergraduate and the other two to final year high school), but your stuff on entropy was a bit beyond me. I see the principle of genetic information which shapes our bodily functions and shapes in an engineer's light. The information must be separate to the matter on which it is stored (DNA - amino acids and proteins) like the information on this post being stored on a hard drive server somewhere. I don't understand how entropy influences the difference between matter and the information needed to communicate something.

    If you read Philip Johnson, you will find that, like me, he recognises the value of all science and does not have a young earth understanding of the world. But by applying his legal mind to the arguments of Dawkins et al, he can see the lack of evidence for their atheistic philosophy…that's all he concludes. The problem as Philip Johnson sees it, again as a lawyer, is that that the atheistic or deistic philosophy which results from their science supports much of today's law and ethics.

    RuthW, it appears we do keep different company. Sadly, most of my friends are engineers, architects and medics (mostly dentists), I think I know two English grads. My engineering and medical friends have a strong scientific background and are generally reluctant to consider the God of the Old Testament who parted the Red Sea and raised Christ from the grave, because Darwinism has 'proved' that God is dead, or at best doesn’t get involved in the world.

    Let me finish with a quote from an article in the Guardian newspaper recently. There was an article on the evolution of the tribes on the Andaman Islands. Throughout the Prof Singh stated that his research contradicted other theories, especially 'Out of Africa', but that in general he remained confused and that further research was required. The article concluded with the following quote from Prof Singh:

    quote:
    "These people have been able to survive by natural selection without any interference from modern medicine for thousands of years," he said. "Their genes are living proof of the survival of the fittest."

    That statement was at best misleading and at worst untruthful. No doubt, the Andaman people have survived 60,000 years isolated from the mainland and they must have been fit to do it. But, in the context of the article, which was trying to provide answers for the origin of man, it implies that 'evolution' (step-by-step development from apes) is a fact (living proof) which needs no further proof.

    What would be the truthful conclusion to the article? I fully support the search for the missing link (the proof) and empirical evidence to evolutionary theories, but Joe Public (including Guardian readers) deserve more than to be convinced that the theory has already been proved. That is not good science.

    Neil

    PS…I must force myself to checkout for the next ten days. I've got a sermon to prepare on Pslam 81 and need to focus myself to the task. Thanks again for your patience with me, sorry for all the long posts, perhaps we can pick up the thread the week after next.

    Neither does anyone else. It's not the same meaning of the word "entropy". For example "right" can mean the opposite of "left" or it can mean "correct" or it can mean "entitlement". That is what I was trying to explain about "entropy". The confusion and lack of understanding has arisen because some YECs have (deliberately in my view) confused the two meanings of the word so that the Second Law of Thermodynamics can have for them something to say about information. It hasn't.

    Richard Dawkins seems to me to have a very limited understanding of what science isn't about but that doesn't stop him from talking about it as if it were a religion.

    I don't think that many scientists or atheists agree with him particularly and they certainly don't see him as a philosopher of merit. To tar all scientists or even all biologists with the same brush as him is unfair.

    Very much so.

    I don't have an awful lot to add, and we don't seem to be getting very far. Neil seems to remain convinced that evolution, or 'Darwinism' as he prefers, carries an atheistic philosophy. It does no such thing.

    One thing remains seriously outstanding. If evolution is not 'the best supported model', could I please be informed what is? I have posted links to articles that scratch the surface of the massive support for it; I expect the same of any rival model.

    Simple, honest, and wrong. They do not create great problems. Great problems would be observations that are inconsistent with the theory, not observations that merely point out things we don't know.

    What we do know is that if the neo-Darwinian model is incorrect, the truth must look very close to it. And in that evolution is no different to any other scientific theory.

    The following would constitute 'great problems':

    I'd also add that my impression is that the followers of religions with their own creation myths recognise symbolic language when they see it, and aren't idiotic enough to try to force a symbolical description teaching theological truths into a literal historico-scientific straight jacket when it was never intended to be such a literature type.

    I had a few minutes in my lunch hour to put togther my initial thoughts on the '29 evidences for macroevolution'

    I have taken a step back from individual issues and look at the big picture. What has struck me is this:

    When reading a single author, Gould, Theobald, Behe, Johnson or whoever, each presents a coherent arguement which seems to be well established in selected observational evidence.

    But what happens when we start to compare theories? Do we find a unified conclusion? Here's a simple example.

    Douglas Theobald in '29 evidences for macroevolution' says:

    quote:
    The oldest rocks we find on the earth are about 4100 Mya, and they are devoid of any life. For the next 2000 million years, rocks from the Archean have no multicellular life at all, just prokaryotes. Then, 2100 Mya, appear the first fossils of eukaryotes (single-celled organisms with a nucleus). For another 1000 million years, there is still no evidence of multicellular life. The first hints of the existence of multicellular organisms comes from trace fossils of tiny worm burrows, found in sandstone dating at 1100 Mya.

    Near the Precambrian/Cambrian transition, only 580 Mya, in the Ediacaran and Burgess shale faunas we finally find the first fossils of multicellular animals. However, they are very unusual, small, soft-bodied metazoans, and most are superficially unlike anything found today. Precisely as we would expect from the standard phylogenetic tree, the earliest fossils of multi-cellular life are very simple sponges and sea anemone-like organisms (sea anemones and jellyfish are both cnidarians). Around 20 million years later, we find the first evidence of simple mollusks, worms, and echinoderms (organisms similar to starfish and sea cucumbers). Another ~15 million years later, the very first vertebrates appear, though most people would strain to recognize them as such. They are small worm-like and primitive fish-like organisms, without bones, jaws, or fins (excepting a single dorsal fin).


    It all founds fair enough, a logical progression from single cell prokaryotes to multi-cell organisms to vertebrates. Theobald gives the distinct impression of a gradual change with 'bags of time'.

    But then we read Gould on the same matter:

    quote:
    Two different kinds of explanations for the absence of Precambrian ancestors have been debated for more than a century: the artifact theory (they did exist, but the fossil record hasn't preserved them), and the fast-transition theory (really they didn't exist, at least as complex invertebrates easily linked to their descendants, and the evolution of modern anatomical plans occurred with a rapidity that threatens our usual ideas about the stately pace of evolutionary change)…If evolution could produce ten new Cambrian phyla and then wipe them out just as quickly, then what about the surviving Cambrian groups? Why should they have had a long and honorable Precambrian pedigree? Why should they not have originated just before the Cambrian, as the fossil record, read literally, seems to indicate, and as the fast-transition theory proposes.

    Here we have two scientists, one stating that life evolved slowly and the other saying it must have evolved quickly then entered a long period of stasis.

    Which one is speaking the truth? They both can't be right!

    That is an example of contradicatory theories from the same field of science, but the picture becomes much more complex when different fields contradict or question each other.

    So, is there a unified theory for all (neo)Darwinism (inclusive of all theories)?

    The truth is that there is much confusion over the theories in the field of biology. But that is not the impression Joe Public is given by the media.

    My next question is this: is Joe Public given a balanced report of what goes on behind the doors of our universities and laboratories? We see science as unified in the media, but it is apparently divided on many issues.

    Has the fear of invoking the hand of a creator in the creation account of Darwinism driven science into the same mistake as the church when it tried (and sadly still tries) to defend the creation account in Genesis?

    Is the literal understanding of (neo)Darwinism undisputed truth or philosophical dogma for 'the best theory we've got'?

    Neil
     


    Posted by Karl (# 76) on :
     
    Neil - I'd check the date of the Gould quote - I suspect that will contain a clue to the enigma. A lot of late pre-Cambrian fossils have been found very recently; specifically in the Burgess shales and Ediacaran deposits, which bear out the previously untestable hypothesis that the Cambrian fauna evolved from unknown but existing primitive metazoans, and them from unicellular organisms.

    Yes but they both say it evolved don't they? They are just arguing over some of the details.

    I've met Christians who have different, indeed radically opposed views, on certain doctrinal points. Surely you're not saying it invalidates the whole thing are you?

    ...some of the problems you have posited are unrelated to the theory of evolution, aka the Origin of Species, except in sofar as you seem to tenaciously cling to the fallacious and illusory micro-/macro- evolution divide. Most of the problems are "origin of life" problems, within which in the latter stages Darwin-type theories play a role, but only, frankly, in terms of diversifiction, which is clearly species-related in fact.

    Even neo-Darwinism has only the most loose of finger-holds on the origin of life, and is frankly somewhat conjectural at best, until we have a better variety of data.

    As Karl has observed, some early material is now available in much better abundance than previously. However, on a macro-level we cannot be entirely sure of its perfect acuity.

    For instance, any naval archaeologist can tell you that the preservation of carbon-based life forms post-mortem in deep-sea environments is essentially nil*, thus whatever period of the development of life one is at, many forms of life will not be preserved, or rather very poorly represented in the preserved profile, due to their environment of existence.

    quote:

    Which side are Christians on? A commitment to Darwinism or a commitment to truth?

    This presupposes strong evidence that Darwins theories are fraudulent and/or grossly inaccurate - 100 years+ of research have only served to strengthen the fossil evidence in favour of the big picture originally layed out. Therefore, the presupposition is at best very weak; reiterating opposition to Darwin (which you continue to do. Despite your attack being in fact on philosophical Neo-Darwinism - which is in as closely related to Darwinism as political Darwinism is - i.e. only superficially and from completely different motivations).

    As a Christian and a scientist, I see Christianity as a search for truth and science as a search for truth; Darwin's theories have proven highly robust indeed, and neither prove nor disprove God's lordship over the earth, not his role as the cause and shaper of it's creation.

    In other words, I see no contradication and hence no question whatsoever.

    Okay…I'm beginning to get the drift. I apologise for my hopelessly inadequate understanding, and unintentional misappropriation, of the terms used in discussion of things Darwinian.

    I realise my understanding of the science is weak and the arguments I employ regarding neo-Darwinian philosophy weaker.

    Can I just ask one question?

    From the evidence to date, can the National Association of Biology Teachers in the USA make the following statement legitimately?

    quote:
    'The diversity of life on earth is the outcome of evolution: an unsupervised, impersonal, unpredictable and natural process of temporal descent with genetic modification that is affected by natural selection, chance, historical contingencies and changing environments.'

    gbuchanan you said:

    quote:
    As a Christian and a scientist, I see Christianity as a search for truth and science as a search for truth; Darwin's theories have proven highly robust indeed, and neither prove nor disprove God's lordship over the earth, not (sic - nor?) his role as the cause and shaper of it's creation.

    If this is the case, if the theories of life are robust, insofar as they show they way life adapting to its environment, and if God is neither proved nor disproved, why does modern liberal humanism, which has its roots in evolutionary science, have such a strong hold on modern ethics and law? If the basis of their (pseudo)science is evolution, and the theory of evolution neither proves nor disproves absolute morality, why do they have the only voice?

    I am referring to popular media coverage such as

    Does this pseudo science of blaming the gene, which is clearly contrary to Christian theology of personal responsibility and free will choice for our actions, find a basis in Darwinism?

    Why is there so little debate in the main stream media? Has Christian theology been sidelined in these cases by the 'fact' of evolution, which in turn supports neo-Darwinian philosophy (like the NABT statement I quoted above) which in turn supports the kind of behavioral science I mentioned?

    I hope I have used the terms correctly. Surely, if Christians show the world that the theory of evolution does not extend to the proof or otherwise of God, then we should have a louder voice in matters of behavioral science.

    A 'rape gene', if it exists, does not contradict Christianity. We still have free will as to whether we follow the promptings of that gene.

    The statement about evolution being unsupervise and unpredictable is correct, from a scientific viewpoint, and that is all it means. I have no problem with it. History is the same - contingent, but by faith we believe God works His will through it. Evolution is the same, but this is not part of the science.

    As regards beauty in women being selected for evolutionarily, I'd be surprised if there was not a selection pressure of this type.

    (oops, looks like the software can't cope with a quote within a quote...)


    Neil,

    Don't worry about the science, worry about the philosophy.

    My understanding is that science is methodologically incapable of concluding that the universe is purposeful or purposeless, designed or random.

    The step of reasoning from random process in nature to purposeless universe was always philosophically flawed, thus in the unlikely event that a totally different scientific theory of origins becomes accepted in science, it should make no difference to the church.

    Imagine you're watching a play, and one of the characters on stage rolls some dice, and says "double 6! I win!" and this goes on to be a significant element in the plot of the play. Within the context of the play, this is a random event. But the play had a writer and director and the outcome was fully intended by them. Science can't tell us about the off-stage writer and director; it only tells us about the little universe we find ourselves in. All the world's a stage...

    If by "unsupervised" NABT are saying that any biological theory proves an absence of divine intervention, they've made a philosophical error. If they mean that it is not necessary to postulate divine intervention in order to understand biology, then seems to me they're right.

    You've raised an important question. I think you're right in suggesting that lots of non-believers have gained the impression that science has somehow disproven Christianity, and that this is a serious issue for the Church.

    But the answer is not to try to improve the science in the belief that a better theory will necessarily give a pro-Christian outcome.

    Still less to engage in dogmatic creationist pseudo-science.

    The answer is to tackle the fundamentalists. Those within the church who bring Christianity into disrepute by linking it with historic ideas of this world - that we now know to be untrue - do far more harm to Christianity than does the outright opposition of honest atheists.

    The Church needs to ensure that its house is not built on the sand. That spiritual truth isn't being justified by questionable cosmology.

    Christ and evolution are not in conflict. Science and a fundamentalist attitude to truth will always be in conflict. Whether in religion or politics (compare the Nazis' rejection of "jewish physics").

    I strongly dispute that "modern liberal humanism ... has its roots in evolutionary science". And I don't agree that it has a strong hold. And I don't agree that if it had it would be a bad thing. Not everyone, in fact not even a majority or anything like it, are Christians. The ethics and law should in my opinion reflect the views of a representative cross-section not some small minority with a loud voice.

    But even ignoring all that, it isn't a reason to attack the theory of evolution. It's just a tool in the scientific armoury so to speak. Like any other tool it can be abused. Would you want to ban hammers because people could go around whacking people over the head with them?
     


    Posted by Wulfstan (# 558) on :
     
    Neil, I think you are leaping around several areas here and I agree with what Russ has said in response.
    1:There are deep disagreements within the scientific community about the mechanisms/speed etc of evolution. This, to my mind, tends to put it in the realm of theory, NOT because there are any remotely plausible alternatives but because we still are sorely lacking in a full empirically supported explanation of it. This would also cover a lot of scientific research, but I'm a great believer in the idea that all scientific knowledge is provisional i.e. we accept it only until something better comes along and that sooner or later it probably will.
    2: Faliure to accept this leads IMO to bad science. I remember some grotesque drivel being produced about girls having a "sociability" gene. The evidence of this was not the isolation of the gene itself but the result of possibly the worst questionnaire in history being given to a pitifully small and ill-defined sample frame producing results that were far from conclusive anyway. The fact that the media did not pick this up straight away was not due to the sidelining of Christian views but on a lack of adequate scientific understanding that allows a select band of charlatans to get publicity without proper scrutiny. More widespread understanding of proper scientific methodology would probably be of more use to your cause than anything else since poorly justified claims like this don't tend to stand up to proper scientific scrutiny for more than 30 seconds.

    why does modern liberal humanism, which has its roots in evolutionary science, have such a strong hold on modern ethics and law?

    I really don't see that it does. In Britain legislation goes through the House of Lords which has a proportion of bishops in it. Both the current P.M. and the Chancellor profess religious convictions which are the basis for their political views (apparently!)Furthermore British law is based on precedents that go back all too often to principles in medieval law which was certainly not based on evolution. Similarly the religious right in the States has considerable influence over legislation and the media.
    I strongly agree with your concerns about bad science but I would view it as just that and not blame Darwin for it.

    As regards beauty in women being selected for evolutionarily, I'd be surprised if there was not a selection pressure of this type.


    These theories are not strictly evolutionary but are extrapolations made by anthropologists to explain behavior. That doesn't make them wrong necessarily, but it doesn't make them right either. They are also prone to muddy this discussion because they are controversies of the nature-nurture variety. How much of behavior is inherited and how much is influenced by environment? This is by no means a settled issue. Selection pressure for beautiful women? I have no problem that male sexual response is hard-wired for a set of common general characteristics, but the fine points of beauty are clearly influenced by society. We can see that the shift of what is considered beautiful happened several times in the last century alone. The controversy happens because theorists wish to draw the line in different places.

    Neil, you might consider that this is why we have theories. The advance of science results from the testing of competing theories, a kind of 'natural selection' that produces a working paradigm. (not a philosophical one)

    Going back to banging on Behe for a moment, his theory of irrreducible complexity is published. It doesn't fit the present paradigm. He may be seen as a nut. If his theory actually has merit, some other scientist will find something that doesn't fit the ruling paradigm. He may publish and/or will find Behe's work from a literature search. Eventually, if that happens enough, people will reconsider his ideas and the paradigm will change.

    But I expect Behe to have a hard pull simply because he is trying to assert and prove a negative. He is trying to say that we can't and we will never be able to explain the evolutionary steps necessary to get to certain complex systems. This is a logical negative, which I was taught is unprovable.

    I really think you are grabbing the wrong end of the stick by arguing particulars instead of going back to the primary disagreement: God or no God.

    As Russ said:

    quote:
    Don't worry about the science, worry about the philosophy.

    My understanding is that science is methodologically incapable of concluding that the universe is purposeful or purposeless, designed or random.


    The way I like to put it, and was going on about in another thread, is either/or:

    That is the disagreement to settle. All else is detail.

    All the best,

    Karl, you said
    quote:

    It will surely not be long now until genetic research gives us the true answer to this hypothesis. Let’s say for now that geneticists find a rape gene, then what you state is true, but only if we see it from a theistic perspective of responsibility. If, however, the science of evolution leads people to conclude that we are only ‘living’ matter, purposeless and without supervision, then we have a problem.

    We have a similar problem in our church in Singapore. That is…no one wants to take responsibility for his or her actions. The only way people see of taking responsibility and of avoiding judgement is to use that phrase of childhood when we’re caught doing something naughty; “it wasn’t me, Mum” and pointing the finger at someone else we say, “he made me do it”. In our church, people say “it wasn’t me, God, the devil made me do it…I have been possessed by evil spirits”. Atheists will say “It wasn’t me, society, my genes made me do it…I am possessed by the natural process of evolution”.

    If a gene is discovered for rape or theft or greed or jealousy, will we deduce that we have moral responsibility? If evolution of humans from cosmic dust is unsupervised, random and material rather than supervised, planned and made in the image of a Righteous God, then we can blame the process and literally get away with murder, or rape (because it’s survival of the fittest). And I respect anyone who states that because it is truthful adherence to the theory of evolution.

    Russ, you said

    quote:
    The step of reasoning from random process in nature to purposeless universe was always philosophically flawed, thus in the unlikely event that a totally different scientific theory of origins becomes accepted in science, it should make no difference to the church.

    Can you explain how your statement fits with what I pointed out above?

    You also said

    quote:
    I think you're right in suggesting that lots of non-believers have gained the impression that science has somehow disproven Christianity

    My wife and I went to see the film ‘evolution’ last night (her choice). It was a great Saturday night, switch of your brain and laugh affair (has anyone seen it?). What I found disturbing is the subtle reinforcement of the ‘life came from outer space’ theory and the single cell, mutiple cell, flat worm, dinosaur, Neanderthal progression (in 4 weeks not 2 billion years) both of are yet unproven theories. However, Joe Public will have a lasting impression from the film that both theories are true…Ruth, here’s your Straw Men.

    Then you said

    quote:
    The answer is to tackle the fundamentalists. Those within the church who bring Christianity into disrepute by linking it with historic ideas of this world

    I agree, and this is exactly what Johnson and Behe were doing. Neither of them holds a historical ‘Genesis’ view of the world.

    I get the distinct impression from everyone’s post that there is no one who has actually read Philip Johnson’s work. Please prove me wrong. Please list which of the following books you have read…’Darwin on Trial’, ‘Reason in the Balance’, ‘Defeating Darwinism by Opening Minds’, ‘Objections Sustained – subversive essays on evolution, law and culture’ or ‘The Wedge of Truth’. I will assume that silence from any member means that you have read none of the above. (BTW, I went looking for Kenneth Miller and Wills in Borders last night…they don’t stock either, I’ll have to order them).

    John, I will not neglect what you said,

    quote:
    I strongly dispute that "modern liberal humanism ... has its roots in evolutionary science". And I don't agree that it has a strong hold.
    but it needs a post of it’s own.

    Onto Wulfstan, you said

    quote:
    I'm a great believer in the idea that all scientific knowledge is provisional i.e. we accept it only until something better comes along

    Correct, this is real science. Now, I do not want to imply a ‘God of the gaps’ theory, but with an open mind to God, theistic scientists will see the laws of nature which God put in place and which go on working day after day. But they will also see the times (like irreducibly) when science can not find an answer and which required intervention by the creator to move biology to the next level.

    Willy, I get the gist of Behe’s logical negative, but if science can’t prove it then the negative must be true. It seems the lack of probability of irreducibly eliminates the possibility of chance, no matter how many billions of years that chance has had to happen, but it will never be provable.

    Walfstan, I realise that I leapt about a bit in my previous posts, sorry. Remember that I had hoped that we could discuss the life of the church without the influence of the matters discussed in the thread above. We’ve had to go back a few steps and I am relieved that someone agrees that

    quote:
    There are deep disagreements within the scientific community about the mechanisms/speed etc of evolution.
    Surely, it would not be human if we all agreed (just look at the state of the church).

    You said

    quote:
    Failure to accept this leads IMO to bad science. I remember some grotesque drivel being produced about girls having a "sociability" gene.
    Sadly, I’ve noticed that this sort of drivel appears on the BBC World Service with startling regularity. The BBC is almost evangelistic in its efforts to get people to believe that our behaviour is due to our genes (as discussed above).

    I would like to ask you about what you said about law and political leaders in the UK:

    quote:
    In Britain legislation goes through the House of Lords which has a proportion of bishops in it. Both the current P.M. and the Chancellor profess religious convictions which are the basis for their political views

    Going back to my original question on this thread, do you think the Bishops of the CoE have a theology which is untainted by last century’s scientific revelation and the philosophy which accompanied it? I am an Anglican, but I believe that most liberal theology is not a product of pure, clear, unconfused Christian thinking (I don’t mean YEC, I mean the nature of God, the nature of man, the fact of sin, the resurrection of Christ etc). Liberal theologians were honest men making efforts in the latter half of the twentieth century to reinterpret the Bible in the light of what science was stating very boldly about God and God’s role (or lack of it) in the origin of life and man. Most Bishops hold this theology and so struggle with the ‘authority’ of liberal humanism, which stems from Darwinian philosophy (I’ll come back to this John). Let’s say that (neo)Darwinian philosophy is undermined by open and honest doubts of the scientific theory’s ability to explain the origin of life and species by a totally naturalistic means, our theology will adjust (if we allowed the philosophy to pollute or theology in the first place…and I think we all, including conservatives, suffered philosophical pollution to some degree (see previous posts).

    As for Tony and Gordon, the former is alleged to see himself as a modern messianic figure on a crusade to put right the excesses of materialism.

    Behavioural scientists are gaining a strong position at the media microphone (BBC World Service). We are beginning to ‘blame the cavemen’ for our behaviour. Does society need to have yet another means of escaping personal responsibility…’It wasn’t me God, my genes made me do it’?

    None. However he is not short of words to say, and what he has to say does appear in places such as
    this debate with Kenneth Miller which he totally loses in my view.

    As far as I can see, if I don't accept what he says in these "executive summaries" for the web or the blurb "on the back cover", why should I waste time reading the whole thing?

    Time isn't limitless, it is plain to me that he has an axe to grind, a very limited understanding of the subject he's talking about and a propensity not to let that stop him churning out books attacking what amount to strawmen. I'm sure we can all think of authors we have opinions of that we don't feel we need to read the books to verify. Erich von Daniken comes to mind. I'm sure Philip Johnson is a higher level than him, but I'm sure he's still wrong. Dangerously so, in my view, as people take him seriously.

    Turning to Behe a moment, where his argument (and I have read it, not his book) to me breaks down is the whole issue of "chance".

    The real point here is that if a thing is possible, however improbable, then he has lost the argument. If life is like a game in which you have to throw a double-six to start, but you have any amount of throws and no time limit, you will get started eventually.

    If life is so improbable that you need trillions of planets to try it out on and billions of years to do it, fine, the universe offers that and we're the "winners". We might feel unique, like a lottery winner might feel unique, but we just won, that's all. The "losers", as it were by definition, aren't around to argue the point.

    But then again, I don't accept that "Liberal Humanism" has a relationship to "Darwinism", that it has a hold, or it would be a bad thing if it did.

    In two other (quite disjoint) BB's (I somehow find time to subscribe to) of a rather different nature to this one, I see that people are more concerned that the "religious right" are setting about a new wave of "book-burning" and that science will be the first casualty. I'd be more concerned about that myself.

    I like the point about Johnson and Dawkins, Alan.

    Dawkins is too extreme evebn for me, but one memorable phrase stands out about not being able to be an intellectually fulfilled atheist before Darwin.

    Johnson, as you say misunderstands science, but he should be read by anyone hoping to popularise Evolution. He points out the pitfalls in language use that many fall into.

    The problems in Evolution should not be taught before at least 'GCSE' level, and preferably at 'A' level.

    There are known problems in number theory (search for Omega numbers on the net). Should we teach pupils learning maths about the doubts some have about its validity?

    If we examine the Holocaust there are some Historians that have trouble accepting that, does that mean we should teach revisionism in schools? They actually use The same techniques as Creationists.

    Moslems also attack evolution, see here: Evolution Deceit. I have writeen a partial rebuttal to a couple of the chapters in this book.

    Neil,
    Since you seem to be so impressed by Behe’s argument I recommend that you read this review article by Allen Orr which demolishes it.

    http://www-polisci.mit.edu/bostonreview/BR21.6/orr.html

    Orr’s key point, amongst others, is that:

    quote:
    An irreducibly complex system can be built gradually by adding parts that, while initially just advantageous, become-because of later changes-essential. The logic is very simple. Some part (A) initially does some job (and not very well, perhaps). Another part (B) later gets added because it helps A. This new part isn't essential, it merely improves things. But later on, A (or something else) may change in such a way that B now becomes indispensable. This process continues as further parts get folded into the system. And at the end of the day, many parts may all be required.

    Behe's argument fails. Even if irreducibly complex systems exist that does not prove that they could not have evolved, indeed one would expect to find many such systems in existence.

    Your insistence that we believe Behe until scientists can provide the individual steps by which say, the clotting system evolved is asking for the moon. Such steps may now be irrecoverably obscured by the process of evolution.

    Orr deals with several other points and all in all it is an excellent article.

    Glenn, you said

    I've read it. Having read the book, unlike anyone else on the thread, I note that Orr has summarised Behe's observations well, though Behe actually spends 200 out of 300 pages (that’s 60% not 30% of the book - but perhaps Orr isn't very good at Maths) describing five irreducibly complex bio-systems. It is fair for Orr to say that Behe draws no conclusion about the designer, only that he thinks cellular mechanisms look like they have been designed and it is now the job of bio-chemists to prove that there is no designer. That's a great challenge which good scientists will relish.

    I respected Orr's observation that Behe, like me, is disturbed by the ill will between science and theology (though I think we will soon come to this matter on this thread, but not yet). If Behe is seen as a creationist, Orr points out, it is because YECs and Evangelical Christians have been quick to associate with him. But Behe is not a creationist, he's not even an Evangelical. Orr points out that Behe is the 'real thing', unlike creationists. Behe is simply a very well informed (Roman Catholic) Scientist who happens to pose a particularly difficult question for step-by-step random development of molecular mechanisms. End of chat.

    I gather, that no one on this thread has read Behe, and John I appreciate that our time is a limiting factor, but it is not an excuse. If something is important, we should prioritise it. May I humbly suggest that the only way we can form educated opinion about a theory is to read the book for ourselves before reading a potted account and coloured criticism? Everyone, will you please stop telling me to read this or that, I'm getting sick of being patronised…go away and read 'Darwin's Black Box' for yourselves, it is not creationist clap-trap but is a serious challenge to the scientific community. And when you've read it come back with your own opinions.

    Glenn, if you had bothered to read it before condemning it as creationist clap-trap (which it isn't), you would you would know that Orr's main argument (which you proudly quoted) is discussed in the book and Behe demands a more scientific approach. The A's and B's of Orr's theory, says Behe, are scientifically insufficient. We need hard facts, not fairy tales.

    Orr either ignored or misunderstood Behe's argument (either he is wicked or stupid) knowing that scientists are unlikely, as John pointed out, to bother to read the book for themselves. So Orr was free to quote part of Behe's disproof back to us as proof that systems are not irreducible. I'd quote you part of the book, but I think it better you read the whole. Then you'll see that Orr's mistake (or deliberate deception) does not demolish Behe's argument, and that the scientific work still needs to be done.

    I'll say it again for everyone's benefit, I have no issue with the methodological work of science. There should be no ill will between science and theology, but sadly there is and this thread should avoid it.

    Has anyone ever wondered why it gets so heated between scientists and theologians?

    Before I post my next thread, can anyone offer me the scientific credentials of Richard Lewontin? I am reading some of his stuff now, and would like to move the debate up a few levels.

    The operative words here are "if something is important" and I disagree with you about whether it is.

    Other people on this thread have said that their faith is unaffected by the theory of evolution. I don't have faith, neither do I work in biology, but from what I gather from those who do evolution is an extremely well-founded theory.

    Why should I waste time, as I see it, reading a book which won't make any difference to what I think or spend my time on and that people who know anything about the subject matter discussed and whose opinions I have reason to respect say is wrong? Even that won't cover all the subject matter you've brought up either.

    I don't think it's been patronising - you've admitted ignorance or lack of understanding of various issues and yet you're still plugging the assertion (inter alia), unsupported by any evidence, that "Darwinist Philosophy" is "the root of liberal humanism", which I disagree with for one thing and am not convinced is a bad thing for another. Where does Behe discuss such things?

    The tone of comments about "getting sick of being patronised" and "go away and read (Behe)" sound dangerously like the petulant responses of someone who has lost the argument to me.

    It is not necessary to read somebody that trys to include anything supernatural into science.

    It is flawed to begin with.

    Behe's only argument "is I don't know, so God must have done it." Many do know, their was a lot of published work on these subjects that Behe ignored. But even if there wasn't this is an "argument from personal incredulity"
     


    Posted by Glenn Oldham (# 47) on :
     
    Neil,
    I don't think that I have ever used the word creationist in respect of Behe. If I have I apologise.

    It seems to me important to distinguish carefully between two different arguments that Behe may be making:

    1) The first is the greater claim that irreducibly complex systems cannot in principle be evolved by natural selection. This argument fails, and Orr's argument shows why. Orr's As and Bs in his argument are perfectly legitimate since the argument is, in effect that all irreducibly complex systems cannot in principle be evolved. Orr need only show that natural selection can in principle explain some.

    2) The second is the lesser claim that some particular irreducibly complex system cannot have been evolved by natural selection. Here the jury is out because it is hard to see how Behe could prove this beyond reasonable doubt, and proving him wrong by constructing a step by step explanation of a particular case is likely to be exceptionally difficult even if it is actually an evolved system.

    Given that the evidence for evolution is so widespread and compelling and that there are mechanisms which can in principle bring about irreducible complexity many of us feel that the chances of Behe being right about 2 are small. His is a challenge to the theory, certainly, but not such as to throw the theory into crisis at the present time.

    His view also has odd theological consequences - given that God, in Behe's view has allowed evolution to operate, why couldn't God let evolution take care of all cases of irreducible complexity too?

    Glenn
     


    Posted by Karl (# 76) on :
     
    Moreover, Behe postulates (IIRC) that the genetic coding for these 'irreducibly complex' systems was placed into the genome of the original population of ancestral organisms, and left turned off until required millions of years later.

    There is a problem here. Non-functional DNA mutates freely, because there is no selection pressure against deleterious mutations. The DNA would for the blood clotting cascade would not work by the time it was required.
     


    Posted by Neil Robbie (# 652) on :
     
    Glenn, I'll need to take your word for it that some irreducible systems have been shown to have developed step-by-step. Karl, I didn't mean to support Behe's theories, only to back up his challenge to science. Someone needs to answer his questions. Glenn says they have (Orr has not), it has been almost 4 years since Behe wrote his book so it is possible that some science has shown the chemical steps to some irreducible systems. Perhaps someone on the thread might wish to highlight some.

    John, I'm sorry for sounding petulant. I was quite frustrated, because I know what I've read and so can see that many arguments are covered in the books. I wouldn't have to argue the points if you had all read the same books.

    You helpfully pointed out previously, John, that Philip Johnson is not a scientist but a lawyer. I'll get to get to the science supports liberal humanism and vice versa once this argument is concluded. Please bear with me.

    Regarding Johnson, we can ask, what right can a lawyer have to question science? None, right? Scientists are best qualified to question science.

    But, if you would have an open enough mind to prioritise the reading of Johnson's books (I am a Christian and read Dawkins and Lewontin without it affecting my faith and you should have the same confidence to do the same) you'd see that whilst Johnson sites simple scientific examples (examples even a lawyer or an engineer can understand), Johnson's primary concern is not with the science but with unraveling the complex arguments philosophical materialists use to defend their 'science'. Johnson shows, with his lawyer's mind, how defenders of 'evolution' use complex rebuttal techniques which mask the underlying science.

    Allen Orr is a classic case in hand. The formula for rebuttal is classic.

    'Demolition' job done!

    Not at all, says Johnson. The main criticism has been left unanswered. In the case of Allen Orr, Behe asked in his book for scientists to replace A+B=C with the real scientific chemical names and reactions. Can you see the weakness of Orr's response to Behe? It is not that he might be right and Behe wrong, it is that Orr has not given a solid answer as demanded by Behe in 'Darwin's Black Box'. A+B=C is not a valid scientific answer. A+B=C is a fairy story based on a prior commitment to materialism. Read the book.

    Johnson has exposed many more rebuttal examples that are similar and all he is doing (like me but much better - he's a lawyer used to spotting flaws in arguments, I'm an engineer used to designing steel structures) is exposing the argument techniques of philosophical materialists committed to keeping the supernatural out of modern thought. Can you see the difference? When people begin to understand the way scientists argue, the debate will be much more open and, more importantly, honest

    Neil,

    Let me see if I've got this right. You seem to believe that:

    a) It's only a dishonest pre-commitment to a materialistic philosophy which keeps scientists from treating God as a major factor in their theories about how the world came to be.

    b) Honest scientists should be able to draw a distinction between those matters which future scientists may somehow be able to explain, and those things that science will never be able to explain.

    c) Having identified a list of inherently inexplicable phenomena, all scientists should automatically accept a supernatural explanation for these.

    d) That once their false scientific backing has been removed, various unspecified liberal philosphies will collapse, leaving the world a more conservative evangelical and thus better place.

    I have to say that I don't find any of this in the slightest bit plausible.

    I'd really prefer that scientists didn't go on about God. Hawking may think that his research gives him insight into the mind of God, or it may just be a way of boosting sales of his books, but the "how" of creation, however fascinating, doesn't really say anything about the "why are we here?" religious question.

    Perhaps all the "heat" arises because our language isn't very good at distinguishing the empirical and spiritual realms, so that what sounds like a scientific question is actually a philosophical question, or vice versa ?

    Russ

    Russ

    The closing question of your post is indeed part of the complex and unnecessarily 'heated' relationship between science and theology. You said

    quote:
    perhaps...our language isn't very good at distinguishing the empirical and spiritual realms..

    Language is certainly one factor amongst many which contribute to the 'heat' between theologians and scientists. I will clarify this later, rather than jump around the matter.

    Before investigating the relationship between science, philosophy or ideology and theology, can we further consider the rebuttal methods adopted by opponents to creationism?

    In relation to the rest of what you said, you demonstrated a number of the flawed techniques used by Darwinists to rebut scientific challenges which have been outlined by Johnson. Can we use your response an example of the flaws of these arguments? This is not a personal attack, your post merely demonstrates our learned behaviour in light of the evolution/creation debate. And note, that creationists are guilty in many cases of using the same erroneous rebuttal techniques.

    In the context of recent posts, your four point summary refers to the issue of irreduciblity.

    Christians of all persuasions need to unlearn this conditioned response. With clear thinking we will see that it is nothing more than a knee jerk reaction to YECs from what we believe is the only alternative.

    But it is not the only alternative. One technique a omitted from my original list was 'contorting the conclusions'. I didn't say scientists have 'a dishonest pre-commitment to a materialistic philosophy'. I said that scientists have an honest commitment to a materialistic philosophy, it is their coloured responses that are dishonest.

    The honest response to Behe is not to demolish his scientific challenge using the flawed rebuttal methods outlined by Johnson but to acknowledge Behe's challenge and set off to the lab to do some experiments to prove Behe wrong. As Behe said, A+B=C is not science it is a fair story used to mislead Joe Public.

    Has anyone read Richard Lewontin's 'The Doctrine of DNA - biology as ideology' (Penguin books £6.99)?

    The Independent described it as 'the most subversive book to be published in English this year (1993)'

    Stephen Jay Gould said of the book:

    quote:
    'The very best in genetics, combined with a powerful political and moral vision of how science, properly interpreted and used to empower all the people, might truly help us to be free'

    Wake up Christendom! 'Science' has not just claimed but already assumed the moral authority for western culture. Can the Christians on this thread see what has happened? While we've backed science verses YEC, science has stabbed us in the back and buried Christianity with philosophical materialism and liberal humanism.

    The honest position for all involved (scientists, Christains and aetheists) in the debate is scientific agnosticism. A simple statement of 'science is neutral' (which we have already agreed) would be enough to re-establish the possibility of the Almighty in the minds of Joe Public. Christians do not need to be hostile to methodologicalism, science and theology can live at peace. But as soon as science made the claims of Lewontin, and assumed moral legitimacy and as long as science keeps Christians on side against YEC, then science has won the moral high ground, and Lewontin knows it.

    Clear scientific agnosticism is called for. A third postion in the evolution/creationism debate. Sit on the fence, say we can't tell, I'm not saying that we need to give serious consideration to YEC, but to the cretaor. Whatever theistic position we hold, do not agree with the evolutionists who have claimed moral authority through the 'fact' that science proves God is dead.

    Neil - science did not make the claims; Lewontin did!

    I think both sides here are trying to confuse science and philosophy. In Lewontin and Dawkins' case the confusion is obvious. It is the Intelligent Design people whose confusion is not so clear.

    Intelligent Design says (reduced perhaps a little too far, but for the purposes of explanation) 'X looks designed, therefore it is'. But that is a philosophical question. Science does not ask whether the blood cascade reaction is designed, but how the design was realised in the natural world. I agree with ID as philosophy, but not as science.

    As regards refuting Behe in the lab, this has been done and Miller refers to some lab experiments that do just this, so I'll leave that until you've read his book. Besides, my father in law currently has my copy...

    Turning finally to combatting atheist philosophy from the likes of Dawkins and Lewontin - the solution, surely, is to accept the findings of science (and even Behe considers that to reject common descent is ridiculous given the evidence) but to point out how, philosophically, this does not actually have any bearing on the existence or nature of God.

    Karl - sorry, I thought Lewontin's job title 'Alexander Agassiz Research Professor at the Museum of Comparative Zoology, Harvard University.', meant he was a scientist. I note that some of his published papers include:

    I may be stating the obvious to you, but you're a scientist (at least I think you are…what is your field?). You sit on the inside of the impenetrable world of science, at least that's the way it seems to Joe Public.

    In the eyes of Joe Public, the common man, Lewontin's scientific pedigree makes him a legitimacy voice on the matter of science and the world. And Lewontin knows it.

    Here is an abridged version of Lewontin's preface and first chapter 'The Doctrine of DNA - biology as ideology'. It makes interesting reading.

    quote:
    Western society has become more secular and more rationalist, and the chief sources for social theory have become the professional intellectuals, the scientists, economists, political theorists, and philosophers who work largely in universities. These intellectuals are aware of the power they have to mould public consciousness, and they constantly seek ways in which they can publish their ideas.

    For almost the entire history of European society...the chief institution of social legitimacy was the Christian church. It was by the grace of God that each person had an appointed place in society...Even the most revolutionary of religious leaders pressed the claims of legitimacy for the sake of order...

    For an institution to explain the world so as to make the world legitimate, it must possess several features. First, the institution as a whole must appear to derive from sources outside of ordinary human social struggle. It must not seem to be the creation of political, economic, or social forces, but to descend into society from a supra-human source. Second, the ideas, pronouncements, rules, and results of the institution's activity must have a validity and a transcendent truth that goes beyond any possibility of human compromise or human error. Its explanations and pronouncements must seem to be true in an absolute sense to derive somehow from an absolute source. They must be true for all time and all place. And finally, the institution must have a certain mystical and veiled quality so that it its innermost operation is not completely transparent to everyone. It must have esoteric language, which needs to be explained to the ordinary person by those who are especially knowledgeable and who can intervene between everyday life and mysterious sources of understanding and knowledge.

    The Christian Church or indeed any revealed religion fits these requirements perfectly...but this description also fits science and has made it possible for science to replace religion as the chief legitimating force in modern society...

    Not only the methods and institutions of science are said to be above ordinary human relations but, of course, the product of science is claimed to be a kind of universal truth...

    Despite its claims to be above society, science, like the Church before it, is a supremely social institution, reflecting and reinforcing the dominant values and views of society...The most famous case is Darwin's theory of evolution by natural selection...Most of the ideological influence from society that permeates science is a great deal more subtle...

    Our genes and the DNA molecules that make them up are the modern form of grace, and in this view we will understand what we are when we know what our genes are made of...we will know what it is to be human.


    I found the above statement refreshingly honest. Lewontin has stated the truth clearly and concisely…God is dead…science rules ethics, morality, culture, purpose and meaning.

    Joe Public has no way of questioning Lewontin's philosophy because, as Lewontin pointed out, no one understands his science.

    My questions are these?

    The fact that Lewontin is a scientist does not mean that everything he says is science. When folk start talking about philosophy, even if they think it is informed by their science, they are not talking with their scientist hats on.

    I am not a scientist; I'm a computer engineer. I have science A levels and a scientific degree, but that's as far as it goes.

    As to your questions:

    What gives science this legitimacy?

    It doesn't have it. If people look to science for ultimate meaning that is very foolish of them. The fact that so few look to the church reflects the vacuosity of much Christian output.

    What keeps Darwin's philosophical train in motion?

    You need to be specific what you mean here, because I'm not sure. Darwin proposed a scientific model and didn't relate it to philosophy, so I don't know what his philosophy was. I understand he was a theist.

    How will the church counter this legitimacy?

    See my last post. Certainly it doesn't happen by finding gaps in current scientific knowledge and saying 'Ha! Goddidit!'

    Neil, Lewontin is clearly an expert in his field of science, and as such within that field (and probably closely related fields) his views are clearly important and deserve careful consideration. That, however, does not mean that what he was to say in the fields of philosophy or theology (which are outside his field field of expertise) has any greater value than any other amateur philosopher or theologian. I think I said much the same earlier in relation to Dawkins et al.

    I think the quote you gave is actually a fairly accurate description of the way things are (not, of course, how they should be). The general public do tend to give a greater credance to the views of scientists, who have effectively replaced the Church as the source of truth. Now that may be great for the ego of individual scientists, it is not good for society since it results in an implicit rejection of other sources of truth (in art for example) that are not capable of being investigated with the tools of science. As a scientist I am worried by this over emphasis on science; I would be horrified if my thoughts on areas outside environmental radioactivity or physics were considered more worthy of consideration because I'm a practising scientist.

    I'll have a stab at answering your three questions in a later post.

    Karl

    Many thanks for your response, I re-read your last post on the way back from work in the taxi (the joy of Palm computing...I write most of my posts in the taxi too).

    I realised, once I'd re-read past the first line of your post that I agree with everything you said and I agree with everything on your response to my slight rant. Sorry.

    Whew...I am pleased that the science and philosophy, including the philosophy of ID, are now clear in my mind), thank you.

    May I summarise so that you can make sure I agree with you:

    Methodologicalism is science…plain investigation into the way things work. It is by definition natural and requires no philosophical commitment.

    Philosophical naturalism, or materialism are fancy ways of saying that a scientist is committed to finding natural ways to explain everything, due to a prior philosophical commitment to atheism.

    Intelligent Design is a way of saying that a scientist holds a philosophically theistic understanding of the universe, due to faith in a creator God, but without trying to invoke a literal understanding of Genesis 1 & 2.

    Creationism is a way of saying that a scientist is committed to finding scientific ways to explain the creation account in Genesis 1 & 2, due to a prior philosophical commitment to theism.

    Remember, I’m a bear of very little brain. Are these definitions accurate?

    You said

    quote:
    The fact that so few look to the church reflects the vacuosity of much Christian output.

    I couldn’t agree more. I think this is what I was asking in the very first post. Has the church become a subset of the Lewontin view of the world? Is it time we evaluate the theology and presentation of the gospel to a world which demands objective reality?

    My next question was meant to open up some thinking about the complex relationships between science, the media, the public, government and so on. What systems exist which support liberal humanism and the ‘scientific’ philosophy of the West?

    I must go for dinner.

    Talk tomorrow

    This is a bit long, but a response to Neils three questions.

    quote:
    What gives science this legitimacy?

    I would say apparent legitimacy. A general misunderstanding in the general public that sees scientific truth to be in conflict with other expressions of truth, especially theology. Part of this is a result of the way science is taught in schools, as providing definite and reliable answers, which give a false impression of the power of science to reveal all truth, which is then supported by the ability of science and technology to provide solutions to real life problems. It is also partly due to the impression that science and faith are somehow in conflict; through media misrepresentations of how science and faith interact (the conflict model makes good TV) and also the vociferous attack on science from a small minority of Christians who accept a hyper-literal reading of Scripture.

    Interestingly it seems that things are changing. The image of science to be able to solve problems is badly marred by the problems of pollution and climate change brought about by technological advances, as well as concerns about GM food, nuclear power, emerging diseases etc. There is a move within the general public away from science as the only (or primary) source of truth, hence the growth in "New Age" spiritualities, alternative medicines and the like. The challenge to the Church is to gain a hearing as being a genuine source of truth.

    quote:
    What keeps Darwin's philosophical train in motion?

    I'll talk about philosophical materialism, ie the extension of the methodological materialism of science to the philosophy of Scientism that says the material is all there is and science is the only way of determining the truth of the way the material works, rather than "Darwin's philosophy" because it is a more accurate term. As Karl has said, Darwin didn't extend his theory to a philosophy, although many people have included evolution within philosophical materialism.

    This, of course, relates to the comments above. While science is seen as the preferred (or only) source of truth then philosophical materialism is a fairly natural extension of that idea. This means that scientists who hold such a philosophical viewpoint have a ready audience in the general public, because as a scientific expert the impression is they have authority to speak as philosophers. As I've said this is incorrect, but the perception is there nonetheless. Of course, it doesn't help when emminent scientists who recognise that they have no expertise in philosophy, and hence no authority to get involved in philosophical discussion, therefore keep quiet on such issues.

    quote:
    How will the church counter this legitimacy?

    Again, apparent legitimacy. It is not solely the task of the Church to counter this, scientists (whether Christian, Muslim, Atheist, agnostic, whatever) who recognise that philosophy is outside the legitimate bounds of science also need to do their part. The debate has to be conducted in the relevant discipline; countering philosophical materialism by questioning methodological materialism will only alienate the scientific community. Hence, although Behe may have legitimate scientific questions to be answered by the scientific community to use those questions to try and undermine philosophical materialism is counter productive (the same could be said for any attempts to undermine the science from which some people make philosophical statements).

    On a practicle level this means the Church needs people sufficiently versed in science and philosophy with the communication skills of the likes of Dawkins to be able to get Christian views of science into the public consciousness. This means trying to get TV in particular to show things which don't depict some form of conflict between science and faith, and to debunk some of the more persistant myths which support the view that science and faith have always been in conflict. It also means we've got to find ways of supressing those within the church who, through some prior commitment to the nonsense of YEC for example, do see science as the enemy.

    Sorry for the length,

    Alan

    Neil,

    Sorry, I take "conservative" to be the opposite of "liberal", and therefore tend to assume that if you're against the one you're in favour of the other. No offence or straw man intended. If you're not intending to put a conservative argument, you might consider whether the word "liberal" adds anything to what you're saying? Is it simply humanism that you're against ?

    Perhaps we should treat the philosophy of scientists as we treat the political convictions of pop musicians. Each individual has a right to their own view on philosophical and political issues. (But this isn't a licence to ignore empirical findings).

    Can anyone ever be said to speak "for science" ? Not if they're spouting philosophy. Perhaps if they're talking about the method of science and the conclusions drawn from the application of that method...

    I'm happy to leave science to the scientists. It doesn't threaten genuine faith in God (although I think that those who believe in a literal interpretation of Genesis correctly perceive that such a belief is contradicted by "scientific" knowledge). I feel no obligation to agree with (or even to read) books of the philosophies held by particular scientists just because they are scientists.

    So I'm not sure there's anything to get worked up about...

    Is it perhaps the case that most Christians today do not believe that the existence of God can be proved, whereas most Christians in medieval times did think that ? So that we believe in God in a different way than our medieval ancestors did ? Is God now a private conviction rather than a publicly acknowledged fact ?

    If you're saying that the rise of science and increasing knowledge of the natural world has something to do with this philosophical change (has the argument from design joined the argument of the first cause in the philosophical dustbin ?) then I wouldn't argue with you.

    But to suggest that the change is reversible through any particular scientific finding seems to me a misunderstanding.

    Is this where the liberal/conservative thing comes in - are liberals happier with modern pluralism while conservatives hark back to the days of crusades against the infidel ?

    Or am I going round in circles ?

    As a tangent, I think this is the past that the YECs are hankering for. Because if the earth was created in 7 days it needs God.

    In defence of Lewontin

    Various comments have been made about R. C. Lewontin which may have mislead readers of this thread about what his views actually are. Neil quoted/paraphrased a bit from the first chapter of his book The Doctrine of DNA Biology as Ideology as:

    quote:
    Our genes and the DNA molecules that make them up are the modern form of grace, and in this view we will understand what we are when we know what our genes are made of...we will know what it is to be human.

    But this is Lewontin stating the view of biology that the rest of his book seeks to attack and show to be false.

    Neil then said:

    quote:
    I found the above statement refreshingly honest. Lewontin has stated the truth clearly and concisely…God is dead…science rules ethics, morality, culture, purpose and meaning.

    But for Lewontin such reductionism is what he argues against. On page 16 he says that he seeks to

    quote:
    acquaint the reader with the truth about science as a social activity and to promote a reasonable skepticism about the sweeping claims that modern science makes to an understanding of human existence.

    Lewontin has co-authored various articles and books with Stephen Gould and also with Steven Rose, and the three of them have much in common with Neil Robbie in that they are very critical of much of Evolutionary Psychology and the way biology is applied to ethics. (see for example the collection
    Alas, Poor Darwin: arguments against evolutionary psychology edited by Hilary and Steven Rose).

    These people are scientists who dislike the way biological ideas are sometimes improperly applied to people, and naturally get passionate in their protests about it. Bravo, for their part in the debate!

    Glenn, thank you for your clarification...that will teach me not to quote from a book I've not finished reading. I bought it on Saturday and only got as far as the end of chapter one (I'm currently juggling 'Unweaving the Rainbow, the third Harry Potter, Gerard Schroder, Preaching the Living Word and Lewontin').

    Karl, you said

    quote:
    Fascinating. And highly illustrative of the disingenuous way in which quotations can be used.

    Sorry, I wasn't being disingenous, merely quoting without reading the whole...which is, as you say, highly illustrative of why we should read the whole and not just the quotes from criticisms…I'll do you a deal…I'll buy and read Kenneth Miller if you buy and read Michael Behe ;-)

    Regardless of whether Lewontin agrees with us or not, his quotes make a valid and honest point. Science is the current legitimating force in western society.

    Karl, I agreed with you that the church needs to put it's house in order to attract scientists who see Christianity as an empty shell. To be fair, the church has been defending itself against philosophical attack over the last 100 years by trying to adapt to the powerful message of science, but the adapted Christian message has little relevance to everyday life, and Christianity of that ilk has, sadly, become a subset of humanism.

    If this process is to be reversed, perhaps we must not only revert to the original message of the gospel, but at the same time undermine the authority of science to claim legitimacy in the realms of the meaning and purpose of life.

    I've been thinking about my question regarding the systems which keep humanism (liberalism - call it what we will) in place.

    Below is a slightly tongue-in-cheek description of the beliefs, people and institutions of the cult of humanism and the part (neo)Darwinism plays in the cult (what's happened to John Collins? This is what he wanted to discuss)

    Perhaps, if Christians understand the interaction between science and humanism, it may help us establish how theistic scientists can aid the recovery of the role of the church in shaping Western culture.

    Here goes, if anyone wishes to expand or amend these initial definitions, feel free.

    Beliefs

    People

    Institutions & Buildings

    I've been thinking about the role of Galileo et al in the undermining of the dogmatism of the church. Science disproved many dogmatically held beliefs of the church and the church lost credibility and confidence in the process.

    Just as no one within the church questioned its legitimacy in the days of Galileo, are scientists now unwilling to question the legitimacy of science today?

    Please remember that we do not want to advocate a YEC approach to science. But can scientists, like Behe, be part of the dismantling of humanism (liberalism)? If theistic scientists break rank with the established church of science, openly questioning the philosophical assumptions of many scientists (like Lewontin is reported by Glenn to have done…my appetite is whetted again for his book), if theistic scientists publicly announce that science is neutral on the questions of God, how will it effect the (Joe) public perception and authority of humanism?

    Neil

    Neil,
    You say that:
    quote:
    Gould said 'science, properly interpreted and used to empower all the people, might truly help us to be free (from God)'

    from God is your addition surely?

    quote:
    'Grace' - genes which determine our position in society (this is Richard Lewontin's limited definition of grace in his book 'The Doctrine of DNA.

    Again, this is the deterministic position Lewontin is arguing against. It is not a definition he believes in.

    As a liberal christian humanist (if that makes any sense to you) when I hear other Christians protest about humanism I wonder what it is about it that they are objecting to -what is it that they think of when they hear the word 'humanism'? I am deeply suspicious of the authoritarian aspects of some styles of Christianity and I get alarmed that they might wish to impose some drastic limits on free speech (that's my knee jerk private nightmare). I would be interested to know what you see as the alternative to the humanism you seem so opposed to.

    By the way, I did not think you were being disingenuous with your earlier Lewontin quote. Enjoy Harry Potter, (I’m on No. 4).

    I don't really know what planet you live on but all this stuff seems quite unconnected with any philosophy I recognise in the context in the UK of having the most religious PM since Gladstone and in the US (oh well better shut up).

    I'm sligtly disappointed that I didn't read Harry Potter 3 when my wife read it...before no 4! 3 loses something of its suspense when you know Harry lives for no 4. Never mind, it's still very well written.

    You're right, Gould didn't write (from God) I added it as I thought it was implied, sorry for that.

    I realise humanism has numerous definitions, I use it in the modern sense as given in Chambers dictionary:

    quote:
    Humanism (n) literary culture; classical studies; any system which puts human interests and the mind of man paramount, rejecting the supernatural, belief in a god, etc; pragmatism (philos); a critical application of the logical method of pragmatism to all the sciences.

    I realise Christian Humanism is an oxymoron in this sense and that you must therefore mean that your theology is post-Renaissance but pre-Reformation (are you interested in any particular aspect of humanism? Northern European, Swiss, French or English?).

    If your theology includes Christianismus renascens, from a modern perspective, then our faith as Christians is probably similar.

    But, now that you have described your theological position, may I ask how adopting the various adjectives which are used to describe different branches of Christianity help in this context? The context being the unifying of theism in science. John Collins mentioned Islam as the common enemy of the West, but when it comes to science, Islamic scientists share a common understanding of the world as a product of an intelligent design. (Mr Collins your response was illustrative of the type of arguement highlighted by Philip Johnson - attack the person and produce a straw man. Your arguement will hold more water if you stick to the issues).

    Can I ask, Glenn and Karl, is it possible for theisists of every shade and colour stop the petty infighting over our understanding of God and unite under the banner of Intellgent Design as a philosophy?

    In its simplest form, intellgent design as a philosophy (if it grows in public perception) will at least turn people to consider the creator. God will lead people to the truth and, I believe, that the ressurected Christ is the only objective truth which will satisfy the minds of people who have trained to seek objectivity. Liberal Christian Humanism will be one of many branches of theism which will benefit.

    hmmm, hmmm, hmmm.
    Neil, I started another thread a day ago which took up some of the issues you are discussing [Irreducible complexity: a funny story].
    To recap and expand:
    Science is basically about discovering primary causes. To posit "Intelligent Design" is often simply discarded as being uninteresting since it obviates interesting research into primary causes.
    There are other good reasons (theological ones too) for discarding it; but I don't want to get side-tracked.
    Scientists, on the other hand, are also human. Plus they like anyone else want fame, security and fortune; and much of that lies behind the debates surrounding evolutionary theory. Evolutionary theorists are often guilty of sloppy thinking and sensationalism, which makes them much akin to theists on those counts. But it does not disprove the central basis of evolutionary theory (you can also say the same for theism).
    A very good book on the controversies within evolutionary theory (more properly the controversies surronding sociobiology) is "Defenders of The Truth" by Ullica Segerstrale.

    You also wrote:

    quote:
    God will lead people to the truth and, I believe, that the ressurected Christ is the only objective truth which will satisfy the minds of people who have trained to seek objectivity.

    Um, why? I can't see that, sorry.

    You also wrote:

    quote:

    Please forgive me if I advance my opinion that this has been tried before in history? Unfortunately, theological thought is too important not to lead to schisms.

    Finally, one of the reasons why I like this place so much is its atmosphere of cordiality between practioners of extremely different schools of thought. If I may be so presumptious, I find it sad on that basis that you have evolved one attitude from "John" to "Mr.Collins" in your reply here; John may be somewhat abrasive, but I think he has raised some points which need more answering, and in any case I don't think he's abrasive enough to warrant the response you gave just above.

    In any case, in a lighthearted manner, let me observe that there are now at least two people on this thread who have atually read Behe.

    Perfectly. But the leaders of the ID movement don't want that. They want us to unite under ID as a scientific alternative to evolution by natural selection. That is, of course, not an option for those of us who accept the case for the latter.

    I'm not entirely convinced by the Intelligent Design brigade; as Karl does, I'm pretty sure that they are too taken by knocking Darwin.

    Also, I.D. tends to be a very particular take in how God was involved in the creation process, and I'm not convinced at all that it is certainly correct theologically or scientifically - indeed personally I think it's pretty unconvincing both ways - or rather it is easily assailed by what I might term "hard evolutionists". It seems rather close to a house built on sand...

    Philip Johnson's weekly letter on the arn.org webpage makes interesting reading for this thread. Johnson talks about his correspondence with Dawkins.

    Philip Johnson on Dawkins - 9th July 2001

    quote:
    My point is not that his statement is arrogant, but that it is just so much empty rant.

    Reading the article, Johnson gets unwittingly drawn into putting his cards on the table by Dawkins regarding his position on common ancestry.

    However, I've never read Johnson scientifically, the bloke's a lawyer, he should stick to exposing the fallacious arguments of Dawkins statements on philosophy.

    The way I read the article is that Johnson accuses Dawkins, as graciously as he can, of a grossly one-sided philosophical view of the empirical scientific evidence.

    Now, I agree that mixing philosophy with science is a dangerous business and that science should be left to its methodologicalism, but I would like to relate this argument to my own experience to state my view on why theists should unite under an 'intelligent design' banner.

    I was converted from a position of philosophical materialism, secular humanism, call it what you like, by faith in the resurrected Christ (which I believe is objective truth) to philosophical theism. With my conversion came the almost instantaneous view that the world was designed.

    As a simple example. I see that animals consume oxygen and produce carbon dioxide and that plants reverse that process, maintaining the atmospheric balance. Philosophically, I saw this, ten years ago, as intelligent design. There is no way we can prove, using science, that the oxygen-carbon dioxide cycle is a product of intelligence or evolution. We can theorise about it, speculate and hypothesise, but we'll never prove it.

    Is this a valid position all theistic scientists can hold? If it is, why don't theistic scientists hold this philosophy more strongly?

    Getting back to liberal or secular humanism. I commend to you the reading of the Council for Secular Humanism - A Secular Humanist Declaration

    Let me quote some parts of the declaration, to give you the gist of why philosophical materialism is the enemy of Christian, and all other monotheistic, faith:

    quote:
    Secular humanism is a vital force in the contemporary world. It is now under unwarranted and intemperate attack from various quarters. This declaration defends only that form of secular humanism which is explicitly committed to democracy. It is opposed to all varieties of belief that seek supernatural sanction for their values.

    We reject the divinity of Jesus, the divine mission of Moses, Mohammed, and other latter day prophets and saints of the various sects and denominations.

    We believe the scientific method, though imperfect, is still the most reliable way of understanding the world. Hence, we look to the natural, biological, social, and behavioral sciences for knowledge of the universe and man's place within it.


    If you visit the webpage, you'll find that Richard Dawkins is a chief contributor. What does he contribute? Scientific observations and philosophical derivations.

    Before saying anything else, I agree with Dawkins revulsion of totalitarian and sectarian regimes. I am perhaps more patient, but no less horrified in the rise of superstition and subjective spiritualism in the West. We only disagree on where our efforts for education should be focused. I agree that we should each be free, but I do not agree that the freedom Dawkins espouses is real freedom. Jesus said 'know the truth and the truth will set you free, and this brings us closer to the real issue and motivation behind secular humanism.

    Now, back to Philip Johnson who is the secular humanist's chief antagonist, but why is Dawkins finding Johnson's attack 'unwarranted'? On what basis does Dawkins argue that the attack is unwarranted? He can not argue on the basis of philosophy, because it is subjective, so he turns to his 'objective' science as the undergirding evidence for secular humanism. Philip Johson replies, your science is objective but your subjective interpretation is one-sided and misleading.

    That's how the two are linked. And that's why undermining philosophical materialism as an interpretation of scientific empirical evidence is one key to re-establishing public confidence in theism.

    This is not the banner the ID people want us to unite under. They want ID as science, as an alternative to mainstream science. That's the problem.

    As they say in Singapore...ah-yoh, lah! Can not like that one.

    This may be your first Singlish lesson, it means 'I see the problem. We can not argue like that, can we?'

    I agree with you Karl, we can not abandon methodological naturalism. From your post, I think I may be beginning to see the reason for the scientific community's reaction to ID.

    It seems the scientific establishment has labled ID as anti-scientific. But, I have not detected the abandonment of methodological naturalism in any of the books I've read by Behe or Johnson. In Johnson's letter to Dawkins, (which has a hyperlink above) Johnson states that he will accept the age of the earth from any valid scientific source (currently 4.6 billion or more if science changes its mind). Methodologicalism is not his issue for Johnson.

    What is an issue is the adherence to philosophical materialism with the claim that the philosophy has solid empirical grounds. It doesn't, we've agreed that on this thread.

    Turning to Behe, the observations of irreduciblity are simply more complex examples of the carbon-dioxide/oxygen cycle. His view is that empirical science may never prove that irreducible systems occurred by chance or by design, but that philosophically and perhaps statistically, ID scientists see the design in the empiricism.

    May I postulate that the adverse reaction by theistic scientists is because YECs have been quick to adopt Behe and Johnson as their own, when Behe and Johnson couldn't dream of anything worse.

    Can we separate the wheat from the chaff, and see ID as distinct from YEC?

    ID is committed to methodologicalism. It just sees the empirical results with different eyes of faith.

    Methodologically speaking, ID is behind science all the way. There's no twisting science to suit a Genesis account of creation.

    But, philosophically, there is a spectrum, with Dawkins et al at one extreme and YEC at the other. Neither philosophy has irrefutable scientific support, although Dawkins has the support of the massive majority, but not all, of empirical evidence. ID fits somewhere on the spectrum. I'd say if Dawkins is the red end of the visible spectrum and YEC the violet, then ID may be the yellow or green philosophically, with blurring at both edges, depending on the individual eyes of faith.

    Where would other board members fit on the philosophical spectrum? I like the colour green.

    Neil, speaking from myself, I wouldn't see YEC and ID as been in the same camp.

    As you may surmise from my previous postings, I'd think that the problem space is not one-dimensional as in a spectrum; there are several debates which lead on from on to another; philosophical neo-Darwinism moves on from, but is not the same as, the scientific principle of evolution - to portray it as parallel to and continuous from Darwinism is exactly the sleight of hand philosophical neo-Darwinists themselves play; a more accurate representation would be for it to diverge at right angles to the line of evolution vs. creationism at the end point of hard evolutionism.

    I believe that in portraying the path as continuous, you are both supporting the interpretation of the problem space favoured by the neo-Darwinists for their own reasons, which I'd argue that we should all challenge and refute; and that secondly this sets up a tension between faith and evolution which is unnecessary (and further supports the neo-Darwinist philosophers).

    Thus, I can't place myself on the spectrum - though I'm probably close to the intersection of the two lines.

    Many thanks. The perpendicular lines are an interesting and helpful concept. Philosophical position on one line and I think you say the interpretation of the empirical evidence on the other.

    Taking the 3D nature of the problem a step further, perhaps we should view the empirical results of methodologicalism as an object to be viewed like a sphere.

    We orbit the sphere philosophically and our philosophical position is geostationery until we have a philosophical shift of orbit.

    Let’s say Dawkins views the sphere with a geostationary position directly above the North Pole. And YECs view it fixed above the South Pole. Both view allows a very restricted view of the empirical evidence, and neither can see the way the other person views the sphere.

    To move laterally from North to South is to shift one’s philosophical position from atheism through agnosticism through theism to YECism, based on interpretation of the empirical, statistical, scientific evidence.

    To move around the sphere at the equator is to consider all the aspects of the argument with an open mind, seeing both the North Pole and the South Pole. Dawkins and YECs are geostationery, the rest of us can consider new empirical evidence by moving longitudinally around the sphere viewing all empirical evidence with a more open philosophy. Perhaps, as we see new empirical facts, our philosophical orbit will shift in the process.

    I’m orbiting around the sphere, looking at the empirical evidence and slowly shifting from a northern hemisphere scientific agnosticism to an equator or just 2deg south scientific theism.

    Neil,
    I could not unite under an Intelligent Design banner as described by Behe, because he appears to think that there must be non-evolved biological systems for God to be credited with designing the universe.

    But suppose that all the complexity present in our world, including the irreducibly complex systems Behe talks about evolved. Would that make God any the less amazing or any the less a designer of the universe? He still created a universe capable of evolving such complexity. (Is that not a greater feat?)

    Just to clear up some old business, vent my spleen and whatever:

    Neil, I decided to stay off this thread for a bit when it deadlocked over the scientific method as it relates to Behe. I disagree with your logic on this but I offer my apologies for any patronizing on my part.

    Now for the venting: The attitude and assumptions behind the idea that "if you'll just read this list of books, I won't have to explain it" is itself patronizing. People don't need to read Behe, et. al, when multiple critiques of them point out the same flaws in their logic, method, evidence and assumptions. Though I *have* read a fair range of the authors in question, I am not going to submit to a 'required reading list.'

    OK, I feel better.....

    For a few days, this thread struck me as a little 'crusade-ish' between "Wake up, Christendom!," to the analysis and breakdown of the "Humanist Religion" to the call to unite under the Banner of ID. Since the subject is about competing philosophies, I suppose that can't completely be avoided.

    However, it struck me, as an outsider looking in, that the idea of uniting under the Banner of ID is very close to the mindset of the YEC. The only difference is where you draw the line on what evidence you accept and into which theoretical framework you fit your evidence. For example, the YEC feel that any scientific evidence that contravenes their literalist interpretation of Genisis is deception and make that part of their doctrinal purity test. It appears to me that ID sets up irreducible complexity as its touchstone doctrine and insists that only particular analyses of phenomena (e.g. clotting factors) be allowed and that such be placed beyond the reach of scientific investigation.

    From a theistic point of view, I would say no. After all, what good is omnipotence if you can't use it? The universe could have been designed with all these details and factors built in from 'before' the Big Bang. If that were so, all of the astrophysical, geological and biological data would point to the natural formation of our universe, the Sun and Earth and the evolution of life. Of course, that leads back to the question, "Why is there anything?" (I forget who said that)

    I think we all know where we all stand philosophically with regards our view of science. None of us are North Pole philosophical materialists (except perhaps John Collins) and none of us are South Pole YECs (except perhaps Bobr).

    So, how can we be labeled philosophically? Can we be united just north and south of the equator? All those between the two tropics losely unite under a 'design banner'.

    Given that materialists are divided, Gould and Lewontin think Dawkins is an extremist, a fundamentalist, and they more liberal. But Dawkins says in response,

    quote:
    ‘at least he (Gould) is on our side against the creationists’

    Is there a way that theists can united, under a broad banner, even though we have slight philosophical differences (different orbits around the sphere) we can say ‘although we differ slightly philosophically, at least Glenn or Willy or Neil or Karl or whoever is on our side against the creationists and against the materialists’?

    Neil

    BTW, Glenn, as your school cancelled Latin, you’ll remember that I asked if your theology included ‘Christianismus renascens’ which means ‘Christianity being born again’, which was the call of the Northern European Humanists and, as you know, their prayers pre-dated the Reformation. I am praying for ‘Christianismus renascens’. How it is born again will be up to God, it is God's church after all.
     


    Posted by Neil Robbie (# 652) on :
     
    This thread seems to have come to its natural conclusion without answering my initial question. I asked, in light of the increasing uncertainty of science to provide all the answers (especially the most important answers) how our theology or practice of the Christian faith would change?

    I find it encouraging finding an increasing and healthy skepticism regarding the ability of science to provide all the answers, especially as secular humanism rests heavily on science to support its creed.

    Way back in the thread, there was a summary of how humans have engaged in God shrinking since the Reformation. From seventeenth century Lutherans and Arminians exalting God's human creatures to deism and then Immanuel Kant who silenced God. The atheist philosophy of Feuerbach and then to Neitzche who pronounced God dead, and whom Marxists, Darwinists and Freudians decided in due course that they could get on better without

    The process has undoubtedly been reversed since science began to draw a blank, even point toward a creator (I am now reading Gerard Schroder's 'The Hidden Face of God - How science reveals the ultimate truth' which is enlightening).

    When Marxism collapsed a decade ago, the west smugly commented that Marx had taken no account in his ideology of human greed. Christians refer to human greed as part of the very unfashionable concept of sin (rejection of God).

    As Darwinism and the secular humanism it supports collapse (and die) we will look back and comment, 'secular humanism took no account in its ideology of sin'.

    I am looking forward to the next ten years. The philosophical landscape is about to change significantly following the death of Darwinism.

    Neil - clearly you've been reading a different thread to me - I think the overall tone here has been that the construct of evolution may need refining, but it the accepted model by most, and doesn't seem to be "dead".

    Yet once more you continue on the track of Darwinism is undetachably connected to Dawkins et al, which most people don't believe.

    Yet once more you compare Darwinism with Marxism, which is a bit like comparing my car to your fruit bowl.

    darwinism is ideologically neutral - people
    using it to justify a particular worldview
    doesn't mean that darwinism ( whatever you mean by that - can i assume the neo darwinist
    synthesis ) *is* that worldview.

    i don't think many people think that the death of darwinism is imminent - most people
    in the field would say that its stronger than ever.

    The philosophical landscape is changing (I doubt it was ever static to start with), but that change is unrelated to the so-called "death of Darwinism". I would say the biggest influence on the changing philosophical situation is the shift from "modern" to "post modern" ways of thinking.

    To "modern" thinkers the idea that there is but one truth lends credence to the extension of truth determined in one field (eg: biological evolution) into another (eg: philosophy or theology). Whereas the gradual erosion of the concept of absolute truth will probably make such claims (that science can lead directly to philosophy) harder to justify.

    Post modernity offers new challenges and opportunities for the interface between science and faith. The erosion of absolute truth in favour of contextualised truths could result in further comparmentalisation of scientific and religious truth claims into unrelated fields, conversely the situation could develop where the different truth claims of science and religion are seen as having equal validity as complementary explanations of the same reality from different perspectives. I hope for the second possibility.

    "Which of you, by taking thought, can add one cubit to your height?" (Jesus Christ)

    I wish some of the people who think so highly of themselves and their ideas can recognize the humility of Einstein.

    EINSTEIN

    Date: Mon, 22 Mar 1999 18:54:42
    Subject: Einstein's Concepts

    Dear Bruce,

    I'm reproducing the following & sending it to you because
    the best place I have to file it is in my Bruce S. E-mail
    file.

    My immediate answer to anyone about who are my science or
    engineering heroes is Newton & Einstein. Newton's laws of motion
    & gravitation, because they always worked for me for any occasion
    in day to day engineering for anything having to do with motion,
    force, velocity or mass, and I was aware of the accuracy of their
    derivations.

    Einstein, my hero because his deductions based on the
    observed fact that the velocity of light is constant allowed him
    to predict celestial and other facts not previously noticed. In
    particular, in 1905, when asked how he could prove any of his
    theories, he replied that if astronomers knew of any double stars
    that revolved around a common center, if his theories were
    correct they would find that the light spectrum from the star
    moving away from the earth would be shifted to longer wave
    lengths than the spectrum of the star moving towards the earth,
    i.e. the so called "red shift". Sure enough, the astronomers
    looked, and for the first time became aware that this prediction
    was true. Of course, one of his other conclusions was that E =
    mc^2 (m-c squared), where c is the constant speed of light. Of
    course, this, too, was found to be correct and the basis for
    nuclear bombs and nuclear energy.

    Many years ago, I began collecting several booklets of a
    series, Science Study Series" with the best of intentions of
    reading them right away. Most of them I didn't, but now I have
    time, so I am. About the same time, I picked up "The Universe
    and Dr. Einstein, by Lincoln Barnett. The best book I ever read
    on Einstein was "Einstein, His Life and Times, by Phillip Frank,
    1947.

    Anyway, in "The Universe and--------" at pages i , 36, 108 &
    109, I discovered the following quotes from Einstein:

    "My religion," he says, "consists of a humble admiration of
    the illimitable superior spirit who reveals himself in the slight
    details we are able to perceive with our frail and feeble minds.
    That deeply emotional conviction of the presence of a superior
    reasoning power, which is revealed in the incomprehensible
    universe, forms my idea of God." (Quoting Einstein)

    "Einstein more than once expressed the hope that the
    statistical method of Quantum physics would prove a temporary
    expedient. (Quoting Einstein "I cannot believe," he wrote,
    "that God plays dice with the world." "

    "The most beautiful and most profound emotion we can
    experience is the sensation of the mystical. It is the sower of
    all true science. He to whom this emotion is a stranger, who can
    no longer wonder and stand rapt in awe, is as good as dead. To
    know that what is impenetrable to us really exists, manifesting
    itself as the highest wisdom and the most radiant beauty which
    our dull faculties can comprehend only in their most primitive
    forms---this knowledge, this feeling is at the center of true
    religiousness." (Quote of Einstein)

    (Frontispiece) "Frequently called an atheist by those who
    have failed to grasp the meaning of his philosophy, Einstein
    himself was strongly convinced of the creation of the universe by
    a Supreme Intelligence."

    Anyway, whoever may assume scientists and engineers are all
    atheists may be incorrect as regards some of the BEST scientists
    & engineers.

    Sincerely, Al Mar. 22 Mon. 6:50 PM CST

    Gbuchanan, we're going to go round in circles until we each read Behe and Miller. I find it hard to follow the line of reasoning which says "I've read the critics, so I don't need to read the original".

    If I said to you, "I've read Philip Johnson so I don't need to read Dawkins 'the selfish gene' or Gould '8 little piggies", would you say "good for you, Neil, there's no need to read Dawkins or Gould, you've read the critics."?

    Now, here's an expansion of the 3D model of the link between philosophy and empirical science:

    At the poles are the extreme philosophies of atheism and creationism. In between are agnosticism and theism. Dawkins and YECs are 'poles apart'.

    Let's say that the second dimension (longitudinal) is scientific specialty or a narrow field of science. Starting at the Greenwich meridian there are, say, paleontologists. Move to +1GMT there are zoologists. At +8GMT we have embryologists. +12GMT molecular scientists, bio-chemists and so on.

    Scientists in any one field orbit very close to the sphere, seeing great detail of the locality of the empirical evidence and relying at the same time on other scientists to inform them of findings on other parts of the sphere. This is the way science interacts and maintains the 'purposeless, meaningless, material and random' process of 'evolution'.

    Now, the third dimension is the distance we orbit from the sphere of empirical science. Research scientists orbit somewhere just above the ground. Science educated graduates might orbit at the cruising height of commercial aircraft, seeing the empirical evidence and understanding the principles in general. Somewhere with the satellites are the people who think their stomachs shrink when they eat less food, they can see the sphere but have no idea about the details or principles of empiricism.

    The fact is that those who orbit closer to the sphere have always had philosophical authority. Those of us in the outer orbits trust the scientists on statements of philosophy derived from empirical evidence (popularised by Dawkins et al, but scientists can be no less philosophical in organs such as Nature)

    Now, the problem today for the philosophical materialists is that some scientists on the inner orbit (near the ground) are looking at the sphere of empirical evidence and are shifting from 'random, purposeless, material universe' to 'a designed universe' as their observed philosophy, and scientists with a materialist philosophy find this conclusion repugnant and are furious.

    Scientists on the board will no doubt have heard of Thomas Kuhn, who proposed the system by which scientific theories are tested and revised. To summarise the system goes something like this:

    quote:
    Experimental research produces data, and a scientific theory is an interpretation of that data which ties everything together in a coherent system. As more data comes to light, or the original data is scrutinised more carefully, old theories are discarded and new theories take shape. But the time between theories is characterised by bitter controversy

    'Purposeless, material and random' is a theory which supports and is supported by a philosophy.

    A theory of 'design' supports a different philosophy.
    Hence, we have a bitter controversy.

    Are in the beginning of the bitter controversy stage of a shift in the theory of the origin of life and the origin of species? Only time will tell.

    You said,

    quote:
    Yet once more you compare Darwinism with Marxism, which is a bit like comparing my car to your fruit bowl.

    I've already said that Darwin and Marx started at the same point, under the fashionable philosophy of Neitzche (God is Dead). Their products are indeed like my fruit bowl and your car, but their philosophies were closely linked by the fashion of their time. The only difference is this; it was easy for the West to see the problems of the derivatives of Marxism from the outside. Seeing the problems with the derivatives of Darwinism from the inside are proving much more difficult.

    It was dramatic and exhilarating when the people of East Germany were freed from the tyranny of Communism (the godless derivative of a godless Marxism). The collapse of the Berlin Wall was the start of a freedom for the oppressed masses. It will be more dramatic still when the masses are freed as the wall of godless Darwinian dogma crumbles and falls and with it, its greatest derivative, secular humanism.

    And we've already pointed out that you were wrong. Darwin proposed that "The Creator" put the first organisms on the earth. He was never an atheist, although he became agnostic in his later years. 'Origin' is a purely scientific work.

    Which is UTTER RUBBISH and furthermore an OUTRIGHT LIE - firstly, Origin of Species was published when Neitzche was 15 years old - so how on earth could Darwinism have emerged from Neitzche's philosophy? Marx was already an established academic at this date as well - okay, it was 8 years before Captial was published, but his theories were already well developed.

    I don't know what "references" you expect me to read and frankly given your fixation with a few contemporary secondary sources I don't really much care - I have degrees in both Science and History, and the latter rather disapproves of depending upon secondary sources.

    If your sources have articulated to a dependency upon Nietzche from Marx and Darwin, they are categorically and unquestionably being deliberately misleading.

    Yes, I am sick and tired of going around in circles - perhaps if you read the original texts of Darwin et al rather than relying upon some else's hearsay, we all might get somewhere.

    Just to be clear, and before it does get taken the wrong way, Neil, I'm not accusing you of lying - just that anyone who is producing statements to the effect that Nietzche influenced Darwin/Marx in their key works in demonstrably generating an untruth, and such a grave one I doubt anyone can trust their integrity.

    P.S. not everyone agrees with Kuhn's take on science - not by a long chalk, though it is clearly influential.

    Fields of study of like economics or politics deal with human subjects, and as such the conclusions of their various practitioners are somewhat maleable, assuming that people can be convinced in some manner to change their behavior or beliefs. This is not true of physical sciences (e.g. physics, biology, chemistry, etc.). What many of the arguments against Darwinism or evolution (which are not the same, despite a habit people have of lumping them togeter) have in common is the sentiment that they should be rejected because the conclusions drawn are unpalatable or undesirable from a certain philosophical perspective. While forcing fact to fit theory may make for good theology, it makes for very poor science.

    Or, to put it more bluntly, it doesn't matter if Darwin never heard of Neitzche or if he, Neitzche, and Marx got together every weekend for a twisted S&M threeway. The value of a scientific theory is how close it descibes the Universe, not how closely it mirrors your own philosophical prejudices.

    ...an interesting sidenote - but I was referring to the postulation that Marx and Darwin were both influenced by Nietzche - not Darwin and Marx's influence on each other (to clarify).

    I'm afraid that this is another large post, in response to a number of posts, please forgive me.

    I also apologise for the misappropriation of the phrase 'Darwinian' theory in my last post. I acknowledge Darwin's own stated philosophy and when I use the term 'Darwinian' theory, it is in its broad sense as material, purposeless and random, not as Darwin's individual philosophy. What term should we use for such a theory? Neo-'Darwinian' synthesis?

    Glenn said that philosophical paradigms have never been static. This thread is a discussion of just such a paradigm shift. It is not secondary or tertiary issues, but the primary issue of the governing western paradigm.

    Whether or not Marx, Darwin & Neitzche ever met or corresponded, or Neitzche post-dated Marx and Darwin by a couple of decades, the fact remains that they lived under the same philosophical paradigm, which Neitzche neatly summarised. Marx and Darwin were too busy employing their significant intellect in ways that were more practical.

    Glenn pointed out that post modernism is the current western paradigm. Reading the Council for Secular Humanism's statement of belief, we find that post-modernism is a sub-set of secular humanism, because 'religion' is only for weak people who can not face a material world boldly and honestly. What is the basis for secular humanism? According to their Article 8...it's science.

    But science is being 'attacked' by Behe et al, which in turn is undermining the authority of secular humanism.

    The question in relation to science and secular humanism then is this:

    Much of the scientific objection is being made by Dawkins et al who see this as 'unwarranted attack', but on what basis? The scientific challenges are real and empirical. The problem with Dawkins, Orr, Miller et al is that they are arguing philosophically from a philosophically static position.

    Behe et al are not regarded by any of the scientific establishment as making unreasonable or untruthful statements about the complexity of molecular systems. Irreducible complexity is a fact of science.

    I don't believe Behe et al have a strong prior commitment, unlike the creationists, to discredit neo-Darwinian synthesis from a prior commitment to theism. Their conclusion seems to have been drawn, quite naturally, from what the empirical evidence suggests to them, and so their vague theistic philosophy has been reinforced at best.

    This reinforcement of a theistic philosophy is the start of a paradigm shift, given the monolithic commitment of the scientific establishment to materialism before the mid nineteen nineties, any scientists who say life might be the product of intelligence risk ridicule and termination of contract.

    ID philosophy stems simply from the fact that scientists are beginning to see evidence of design. The theory of intelligent design stems from a philosophical paradigm shift from material, purposeless and random to the product of intelligence.

    This is why I make extravagant claims about the death of Darwinism (neo-Darwinian synthesis). It is not because empiricism has ceased, nor will it cease, but that the empirical results are beginning to be viewed from a shifting philosophical paradigm. This paradigm shift is in its infancy. It is barely a decade old. As the paradigm shifts, it will (as all paradigms do) effect law, morals, ethics and theology. The next 10 or 20 years may see this shift accelerate. In the mean time, there will be bitter controversy, because what is at stake is more than just a precious scientific theory, it is a whole way of thinking for society.

    I find that thought exciting and refreshing.

    Neil

    BTW, I have Darwin's 'Origin of Species'.

    What term should we use for such a theory?

    What me, Alan, Glenn and so on have been calling it all along - philosophical materialism.

    Irreducible complexity is not a fact of science, and much ink has been spilt showing how Behe's systems are not unevolvable.

    Neil, You summarise Kuhn and say:
    quote:
    But the time between theories is characterised by bitter controversy ... A theory of 'design' supports a different philosophy. Hence, we have a bitter controversy.
    Are [we] in the beginning of the bitter controversy stage of a shift in the theory of the origin of life and the origin of species? Only time will tell.

    As you say 'Only time will tell'. As I understand Kuhn what presages the paradigm shift is an accumulation of problems which the existing theory is, after repeated attempts, unable to explain, and which tell against the theory. We have a long way to go before that stage is reached. I think it unlikely that it will be.

    Bitter controversy is no guarantee of paradigm shift (astrologers are in bitter controversy with science about their theory but there is no chance that astrology will end up mainstream science).

    The above quote illustrates what is probably one of the worst ways to pursue scientific inquiry. While social "sciences", such as economics or psychology, may concern themselves with the "way of thinking for society", such considerations are (or at least should be) far outside the realm of the physical sciences. And biology, including evolution falls under the heading of physical science.

    I think part of the negative reaction to evolution as a scientific proposition is our own sense of vanity. I have never heard anyone object to either the Special or General Theories of Relativity because they were formed under the "philosophical paradigm" (to borrow Neil's phrase) of Moral Relativism. To cite another example, Einstein himself admitted that his objections to Quantum Mechanics were probably the worst scientific mistake of his life. This objection spawned his oft quoted (and rarely understood) statement that "God does not play dice with the Universe". In essence, Einstein's objections were based on the philosophical unpalatablity (to him, at least) of a probabilistic, chaotic, and (potentially) non-causative Universe rather than any particular physical and scientific reason. Of course, Einstein was at least scientist enough to admit his error when he recognized it.

    At any rate, the reason so many people object to Evolution while there is little hue and cry about Relativity or Q-Mech is that neither of these assault our own ego the way that Evolution does. Both of these theories present radically non-Christian themes, but they don't deal with humanity itself. It wounds our self-image to be taken down from our pedestal as something special and separate from the rest of the Universe, whereas we don't really care about the "moral degradation" of electrons or the current malaise of spacetime.

    Arguing human ego from the biblical side of the coin, evolution is perhaps the product of an oversized human ego. The Hebrew word groups describing worship include 'homage to', 'service of' and 'respect of' God.

    By rejecting God, and appealing to materialism as the mechanism driving 'evolution' man's ego swells beyond humble homage, service and respect.

    As I postulated earlier, the west saw how Marx neglected human greed. Perhaps we'll look back in years to come and see how philosophical materialism neglected the unfashionable concept of rejection of God.

    Several loose points - okay, so people without God can tend to egoise, well so can those who believe that they are God's special messenger, and in between. Much as I may agree with your general drift, Neil, I don't think that the only outcome is a boosting of the ego of humans.

    For example, many coming from the position which you are assaulting believe that, as humans are no more than advanced animals, we should not expect to be able to control the fate of other animals through farming, meat-eating etc. They probably see traditional Christian teaching as egoist.

    Certainly philosophical naturalism does have an impact on the way morals are being shaped in our society, but I do not believe that it really provides a sufficient framework to provide a useful philosophical or ethical baseline - indeed one can argue that Marxism and Fascism were philosophically inspired by the concept of the "survival of the fittest", though in differing directions. I don't think anyone will contest the Origin of Species is a weak baseline for ethics, and most secular philosophers I've heard of would agree - remember that for instance Dawkins is primarily a scientist and scientific philosopher, not a social one, so he is far from being dominant in that other sphere. What many philosophers mean when they use the same label is significantly different, btw.

    It is interesting that you are attacking the moral impact of philosophical naturalism through the science which underpins it. Firstly, ID for example is not science by any means, and I can't see it currying favour before it moves towards something that is testable rather than rhetorical.

    Secondly, the connection between science or even the philosophy of science which emerges from scientific conclusions, has a very poor record indeed in surviving long term or contributing to the general patina of philosophy. Clearly many scientific discoveries and practices, e.g. innoculation, genetic modification, the nuclear weapon, have profound impacts upon moral philosophy and the philosophy and morals of scientific practice, but this is quite a a different phenomenon. Your attack would be much better based upon the inadequacies, well proven, of the route folks like Dawkins are walking.

    Many moral dilemmas and ethics will be impacted by scientific discoveries in the physical and biological sciences, but that's also a different matter.

    P.S. I've actually had to read Behe in the last two days (hooray for a historians' reading speed!) for a tutorial I was assisting in leading on scientific methodology. Oh dear, it is generally bad science - Karl et al were all too generous.

    John,
    Looking at the full text of Croesus's posting I think he is only making the point that whilst the theory of evolution does not make reference to the concept of God in its explanations, neither do Quantum theory or General relativity. Yet christians get up in arms about evolution but not Quantum theory or relativity.

    He suggests that this is because, as to the the theory of evolution

    quote:
    It wounds our self-image to be taken down from our pedestal as something special and separate from the rest of the Universe

    I think that this is correct. In a few hundred years we (in the christian west) have gone from seeing ousrselves as at the centre of a small, young universe, to being on a small planet in an immensely big and old universe. The theory of evolution is seen by some as denting even further our reasons for feeling special. Hence the resistance to the theory.

    Of course being special is possible still even if, as I believe, the theory of evolutionn is correct.

    I'd have to say that isn't how it came over to me, but obviously I could have misread it.

    However I should have thought that relativity and QM would be helpful to the argument (against some Darwinist philosophy).

    Relativity - the speed of light is an absolute barrier that cannot be exceeded. Here's something we can't do. Only geocentrists need complain.

    Uncertainty principle in QM - the more you know about one aspect of something the less you can know about another. We can't know everything.

    So if God is omnipresent and omnipotent he's not bound by relativity and if he's omniscient he's not bound by QM. Surely there's food for a good few sermons out of that?
     


    Posted by Crœsos (# 238) on :
     
    That was my point only in part, Glenn. Certainly someone who rejects Evolution for its absence of God and its appeal to materialis in its theorization must do the same for Relativity and Quantum Mechanics (and Plate Tectonics and Genetics and Optics and . . . ). All these are Godless, materialistic scientific theories.

    As far as Neil's question about what is non-Christian about Relativity and Quantum Mechanics, allow me to clarify.

    Relativity presents us with a Universe where space and even time are relative, dependent upon one's frame of reference. If A happened before B in one reference frame, it is possible for B to happen before A in another, posing all kinds of problems for cause-effect order. Time itself is malleable and can shrink down or expand out. A length of time which is six days long in one frame of reference may be 14 billion years long in another. The Relativisitic Universe is a Universe which denies absolutes and everything is a matter of perspective. This is very different than the Christian Universe which contains an absolute God who deals out absolute truth and perspective is irrelevant. Considering the number of times I've heard various Christians decry "moral relativism", the analogy to physical Relativity doesn't seem so much of a stretch, and I'm surprised it hasn't suggested itself to more Christians before this.

    As far as Quantum Mechanics goes, it presents us with a probabilistic Universe, one driven by chance and chaos. This is a radically different Universe than the Christian Universe, in which God has a Divine Plan, which is deterministic, immutable, has even the smallest details worked out in advance, and cannot be thwarted or changed in any way. The philosophical gulf between these world-views is a question of Schroëdinger's cat versus God's falling sparrow.

    These and other questions might be better addressed if more time was spent considering Darwinist science (or any other science for that matter) and less time worrying about "Darwinist philosophy" [from John Collins post of 28 July 2001 09:57].

    And as for how I get the 'o' and the 'e' to stick together, I exist in a frame of reference where space is contracted enough that some letters actually touch. Besides, it has been established that vowels are not Fermions, and are thus not bound by the Pauli Exclusion Principle.

    Posted by Neil Robbie (# 652) on :
     
    Sorry to interjecting and digressing from the current issue, I've just clarfied my arguement in my own mind.

    I have been accused of attacking science, and believing bad science. I am probably guilty of both, I don't know. Perhaps my misappropriation of the myriad of terms used in this field has led to that impression and my confusion. The reason I have been so persistent is I know that my argument is true, I just need to be clearer about what I'm arguing.

    This morning, the good old BBC World Service provided an example which will clarify my argument. The article shows that I am not attacking good science, but I am attacking philosophical materialism dressed up as science. On the BBC this morning, scientist Heather Cooper provided a perfect example of what I have been attacking as 'science'.

    Cooper was describing the work of the 'Genesis' space probe, which will sample particles from the solar wind and bring them back to earth for analysis. The mission will take two years, so we can expect results of this research in perhaps 4 to 5 years time at the earliest. So far, so good science.

    But then Cooper said this

    quote:
    'What I find incredibly exciting is that 'Genesis' will explain our origins. We will know where we come from and how we got here.'

    My point throughout this thread, though not put clearly, is that that is not good science!

    It is at best hopeful speculation that the particles of solar wind will provide one of the many hundreds of missing pieces in the 'origin of life by natural process' puzzle.

    But worse than that, Cooper's statement is of a prior commitment to philosophical materialism. She states boldly that it is just a matter of time before scientists find and place all the hundreds of missing pieces of the puzzle, proving the natural causes, and disproving God. Is Cooper's prophetic statement based on scientific fact or faith? I say faith.

    Lastly, Cooper's confident, bubbly, cheerful and excited delivery (which I can not replicate in the quote) gave the listener hope that what she said would come to be. She practically adopted the style and techniques of a TV evangelist. Indeed, naming the probe 'Genesis' has to be one of the most barefaced statements of how science will provide our new creation account, without God.

    But, there was no science in her statement, just faith and hope in philosophical materialism. If I wasn't skeptical, I might have believed her. My concern is that millions of World Service listeners will have swallowed her 'scientific' statement and will go on believing that God does not exist.

    Collecting particles from the solar wind is good science, I have never intended to argue otherwise. The rest of Cooper's statement is just wishful thinking, faith and hope in material causes.

    Heather Cooper, like every other philosophical materialist, does not wish to consider the prospect of moral accountability to a creator God. I don't have a problem if that is her choice of religion, she is free to chose her faith. I do have a problem that she is given free reign to proselytise and evangelise freely under the label of 'science' when she is clearing talking about matters of her religion.

    One of the things that makes materialism so easy to have confidence in is the fact that it produces results, verifiably and unambiguously. In the few centuries that materialism has been ascendant, science, a materialist process, has learned to launch heavy metal planes into the air, and just as easily it can rain missiles down on cities. It can prevent polio, and it can destroy whole cities in a single atomic blast. It can allow millions of people all over the globe to exchange information with the touch of a few buttons, and it can just as easily spy out our secrets. Whether applied for good or for ill, materialism gets RESULTS! I'm not sure that something whose effectiveness has been borne out time and again can really be called "faith". (At least not in the religious sense of the word.) And to examine a competing world-view, all that religious faith has to show for its millenia of effort is an assortment of burnt heretics and holy wars.

    Now as for the specific statements of Ms. (Dr.?) Cooper, many scientists, particularly those involved with particle physics and/or space exploration, do tend to get caught up in grandiose language. I can't speak for her specifically, but I suspect that it has something to do with repeatedly trying to explain very abstract concepts to laymen (in the scientific, not ecclesiastical, sense). I've also noticed that this tendency tends to be directly proportional to the attention of the media, though this last seems to be true not just of particle physicists but of people in general.

    At any rate, materialism seems to be emminently suited to the study of material objects and phenomena, which includes solar particles and biological organisms. I have yet to hear either an argument in favor of the wholesale abandonment of scientific inquiry or a suggestion for a suitable replacement for materialism in the scientific process. Perhaps Neil could suggest one, since this issue seems to be of particular significance to him.

    I don't take that statement that way at all! All she is talking about is our physical origins, the way in which life came to this planet. This is perfectly good science; whether or not the probe will tell us this is another matter.

    Neil, you still seem to be wed to the idea that if it is shown that the entire Universe, and us included, can be explained in scientific terms, without invoking God as an explanation, then God will be disproved. This is a load of rubbish. If the Genesis probe does explain our origin, then great, another piece in the puzzle of how God made us is found.

    Why do you require unexplained scientific questions for God to exist? This seems to be 'God of the Gaps'ism of the first degree.

    There is no need for me to suggest an alternative to the study of material objects, I have never meant to propose one. The study of material objects is a good and healthy pursuit. What is not good and health is atheists claiming that the study of material objects disproves God. This thread has already agreed that the study of material objects is neutral on that question.

    Regarding your own response to my example of Heather Cooper, you can not seriously mean that the Boeing 747, telephones and vaccines disprove the existence of God. You also used a classic 'religious' straw man of holy wars and burnt heretics as the alternative. May I humbly suggest you read the outline of fallacious argument techniques I outlined earlier in this thread before posting such thoughts, they do not address the issue.

    Scientifically, I am as excited as Heather Cooper at the prospect of collecting particles of solar wind using a space probe, it is an amazing result of science. I am as excited as you that science has advanced to the stage that we can send probes into space, and that I can write this post on a Palm device whist eating lunch. The products of the investigation of the material world are exciting and useful.

    However, with reasonable skepticism, something we should all posses in large quantities, I can see through Heather Cooper's science to her probable underlying philosophy. She appears to believe that there is no God. That's fine, I don't have a problem if that's what she believes, it's her choice.

    But when she speculates that the 'Genesis' probe will provide the final pieces of the materialist creation story, my skepticism tells me she's no longer in the realms of science but philosophy, day dreaming, thinking wishfully, postulating, putting an atheist spin on it, proselytising the public, evangelising her belief that God does not exist.

    She's entitled to do that, but she needs to be honest that that is what she is doing. She should clarify that this is her belief (if that is what she believes). She should say that she hopes that the probe will provide some clues, because that will support her alleged philosophical belief that God does not exist. To say that the probe will tell us the origin of life it not a true statement. How many scientists believe that the only piece of the puzzle which it missing are particles of solar wind?

    My problem is this: that Heather Cooper is typical of philosophical materialists (if that is how she would label herself) who evangelise their atheism or deism, illegitimately, under the banner of science. Saying 'solar particles are the last piece in the puzzle of the origin of life', is not good science it is bad philosophy.

    All I propose is that we learn to distinguish between the times when scientists are talking about material objects and the other times they are proselytising their materialist atheist faith.

    The answer is quite simple. I don't believe the universe is the product of a random, material, purposeless process.

    I believe, as I pointed out with the carbon dioxide-oxygen cycle, that the universe displays evidence of specified complexity.

    Specified complexity is displayed by any object or event that has an extremely low probability of occurring by chance, and matches a discernable pattern. According to contemporary design theory, the presence of highly specified complexity is an indicator of an intelligent cause.

    As a simple illustration, I am a structural engineer...no jokes about engineers being simple please. As an intelligent designer, I must specify the grade of steel, size of weld, diameter of bolt, length of beam, depth of concrete and so on to make a building stand up. Any school child can draw a house, but it takes intelligent specification to give the right combination of materials and sizes to make the house stand up.

    Engineers who design manufacturing processes have a much greater complexity to their specification to get the process to produce the right goods at the end of a process (anyone who knows anything about the production of semi-conductors will know what I mean).

    I believe that the results of objective study of material objects display this specified complexity. This is a purely philosophical view as someone else looking at the same results might see them as the product of a purposeless and random material process.

    It is a simple distinction. It is not God of the gaps, because everything is specified.

    It's based on the historical fact that science has, indeed, gradually explained more and more of the universe. That we may get a fully understanding of abiogenesis is a reasonable extrapolation.

    As for 'specified design' - well, yes. Of course. But this is not an alternative to naturalistic explanations, but complementary to them.

    How did I come to be? Human reproduction, sex, gametes, chiasmata, embrylogy, diploidy - lots of things come in to it.

    Why did I come to be? God so deigned it.

    Who caused me to come to be? God on one level, my parents on another.

    See - lots of complementary explanations. Only the first one of those is in the realm of science. The others are not, and for the same reasons, nor is ID.

    I agree with SA that it wasn't random and purposeless for a reason I gave earlier on this thread.

    An overall process isn't random if "failures" are eliminated, which is exactly what natural selection does.

    To take a bizarre illustration, if everyone who did the lottery and didn't win the jackpot were instantly shot dead, then everyone in the country who had played the lottery would be a winner. If someone then said that these lottery winners "couldn't have got there by the random process of the lottery" they'd be right.

    In the lottery of being here, the penalty for losing is - not being here.

    If the odds against being here are 1 in (however many planets there are in the universe) over (the age of the universe) and that one planet is the one we're sitting on we may feel very special, but we're not. None of the other planets have got signs up saying "congrats Earth, we didn't make it" because there is no one to put them up.

    It is a simple distinction. It is not God of the gaps, because everything is specified.


    Now you:

    quote:
    As for 'specified design' - well, yes. Of course. But this is not an alternative to naturalistic explanations, but complementary to them....lots of complementary explanations. Only the first one of those is in the realm of science. The others are not, and for the same reasons, nor is ID.

    This means we agree, doesn't it? ID is a philosophy. ID is not science, but a way of viewing the results of methodical science into the way material objects function.

    Just to make sure. Please explain what you mean by naturalistic explanations

    No, I don't mean that and I didn't say anything even remotely like that. What I indicated was that these are examples of the validity of materialist examination when dealing with material phenomena, the validity of which you, Neil, called into question with your posting of 30 July 2001 02:05.

    Which begs the question that if there is a dividing line between what material phenomena can be investigated rationally and those which are "Not Meant for Man to Know", where is that dividing line and how do you determine where it is?

    As far as the question of specified complexity goes, it is only significant if it can be demonstrated that other combinations of events have a significantly higher probability of occurring. For an American example, last year's professional baseball season had an extremely low probability of working out the way it did, hit for hit, strike for strike, and run for run. And given the fact that baseball follows a structure of rules it can definitely be said to have a "discernable patter". However, the fact that there was a baseball season last year and that it worked out in such an improbable manner does not mean that it was divinely ordained, or even that some human agent fixed all the games in advance to work out the way that they did.

    What troubles me most is Neil's statment that

    quote:

    If it is a "purely philosophical" view, then how is it an "objective study of material objects"? If you're going to be injecting your own "philosophical view", your study can hardly be described as "objective".

    Thank you, that is exactly my point. If you are a philosophical materialist, you look at the results of science as purposeless, random, impersonal, undirected, meaningless or in other words, godless. A philosophically materialist conclusion is not objective. It is philosophical.

    Karl, you and I do not agree after all. If all deductions from the scientific observations are that the process are

    quote:
    Explanations that make no mention of, nor make any reference to, nor ascribe anything to, God, a god or gods. Or anything else supernatural.
    , then there is a subtle difference to the way we view material objects. You seem to say you think things are specified, but then disagree that God could have specified them.

    Let me give an example from mutation-selection.

    Here's a quote from Elliot Sober's, Philosophy of Biology.

    quote:
    The fact that the mutation-selection process has two parts…is brought out vividly by Richard Dawkins in his book The Blind Watchmaker. Imagine a device that is something like a combination lock. It is composed of a series of disks placed side by side. On the edge of each disk, the twenty-six letters of the alphabet appear. The disks can be spun separately so that different sequences of letters may appear in the viewing window.

    How many different combinations of letters may appear in the window? There are 26 possibilities of each disk and 19 disks in all. So there are 26 times 10 to the power of 19 different possible sequences. One of these is METHINKSITSAWEASEL…the probability that METHINKSITSAWEASEL will appear after all the disks are spun is 1/2,600,000,000,000,000,000,000,000,000,000, which is a very small number indeed…

    But now imagine that a disk is frozen if it happens to put a letter in the viewing window that matches the one in the target message. The remaining disks that do not match the target then are spun at random, and the process is repeated. What is the chance that the disks will display the message METHINKSITSAWEASEL after say, fifty repetitions?

    The answer is that the message can be expected to appear after a surprisingly small number of generations of the process…

    Variation is generated at random, but selection among variants is non-random


    Now, Scientifically, we have observed that DNA sequences are not random but contain codes, or language. So, Dawkins has proposed that DNA sequences form a bit like the words in 'The Wheel of Fortune' or 'Hangman', where once a letter is in the right slot it slicks. Perhaps he was thinking of a one arm bandit with a hold feature, which allows the player to freeze a wheel.

    Can you see the flaw(s) in this argument?

    Neil,
    Let's make Elliott Sober's argument clearer by adding what he says immediately following the part you quote (p38):

    quote:
    Although the analogy between this process and the mutation-selection process is not perfect in every respect, it does serve to illustrate an important feature of how evolution by natural selection proceeds. Variation is generated regardless of whether it "matches the target" (i.e. is advantageous to the organism). But retention(selection among the variants that arise) is another matter. Some variants have greater staying power than others.

    ... Variation is generated at random, but selection among variants is non-random.


    This makes it clear that the common feature between the discs making METHINKITISAWEASEL and DNA in this analogy is random generation plus non-random selection, not some other feature.

    Hence I cannot see a flaw in Sober's argument. What flaw(s) do you see?

    I'll try to deal with each question I was asked in response to my question 'can you see the flaw(s) in the argument', before asking further questions.

    Gbuchanan, you asked

    quote:

    That is exactly what I intended, and have been trying to say all along - that we can all view the results of mechanistic processes through one of two philosophical eyes - either atheist or theist, unless you can propose a third way of considering mechanistic objects philosophically.

    Karl, you have helpfully stated that you wear two hats, a scientific hat and a Christian hat. Well I wear two hats, an engineering hat and a Christian hat. I hope my engineering hat will help you see the way specifications fit into the picture, just as you and other scientists on this thread have helped sort out much of my messy thinking about science.

    But first, let me start by asking you this question. Richard Dawkins famously said of Paley's watch something like (this is my paraphrase)

    quote:
    biological organisms give the appearance of being designed, without having been designed

    How does that statement differ from what you said that science is finding

    quote:
    Explanations that make no mention of, nor make any reference to, nor ascribe anything to, God, a god or gods. Or anything else supernatural.

    Is there a philosophical difference? I can't see one?

    Glenn and Alan, can I come back to your questions about the flaw(s) in Sober's argument once we have clarification on the question I have asked Karl?

    Neil
     


    Posted by Karl (# 76) on :
     
    My point is this - the issue of design is not part of science, and so questions about 'was this designed' are not part of science.

    The thing is, Dawkins' statement there is philosophical, because it addresses a 'how' question. My statement was about the nature of science. That is the difference - they are addressing different questions.

    Let's cut to the chase. The difference is that you seem to think that 'there was an intelligent designer' is a valid scientific position, I think it is in the realms of philosophy.
     


    Posted by Glenn Oldham (# 47) on :
     
    I think that the point is a tricky one.

    The question of an object having been designed by an intelligence rather than being the result of non-intelligent processes is a legitimate scientific question. In the search for extra-terrestrial intelligence we have to think of ways to try to determine if certain radio and other emissions from space might show features of design. An archaeologist looks at an artefact or site and tries to determine if regularities in its features indicate any element of construction by an intelligence rather than by non-intelligent natural forces alone. Suppose too, that humans went extinct and another intelligent life form evolved in a few hundred million years time. Their scientists would have to assess whether artefacts preserved from our time were naturally evolved or intelligently designed.

    In these cases we (or the future scientists) can compare the artefact or emission with our ideas of how we might design things, or, for the archaeologist with examples of similar artefacts known to have been made by other cultures.

    Behe’s claim that certain biological systems are designed is thus not one that can be ruled out as unscientific. However, the only means for assessing his claim is to pursue research into whether natural unintelligent processes could have evolved the systems in question i.e. carry on sciense as normal. He believes he has shown natural explanations of these systems to be impossible, others disagree and think that his arguments are flawed. There is no reason in principle why natural selection cannot evolve irreducibly complex systems, but at the moment our knowledge of biochemistry is insufficiently sophisticated to ascertain the steps involved in his example cases.

    There is a bigger issue behind Behe’s views and that is the question of whether there should be a theistic science, one which has an explicit place for God’s direct actions in its explanations. The problem with this is how to determine when God’s action needs to be invoked. Do we defer to some persons interpretation of scripture or other alleged revelation from God? Surely not, how do we know he/she is correct? One way we would have to try to test such claims is by trying to see if an explanation can be constructed that does not rely on God’s intervention. In other words we would do what scientists already do, operate using a non-theistic methodology. Science is thus necessarily non-theistic, but since this is only true of its methods it need not be a worry to anyone.

    Neil,
    I see that Robert Pennock says in his book Tower of Babel that Behe criticises Sober's argument about the METHINKSITISAWEASEL letter discs by pointing out that an intelligence is doing the selecting of which letters are fixed in position after each spin.

    But this is to miss the point pretty thoroughly. The analogy, as I explained in my earlier posting, is about random generation plus non-random selection i.e. it is about the power of cumulative selection. Both Sober and Dawkins make this clear in their discussion of METHINKSITISAWEASEL. Any system which replicates itself reasonably faithfully but with some variation will evolve if there is non-random selection of the different variants amongst the offspring regardless of whether the selection is done by intelligent or non-intelligent processes.

    Pennock is excellent on this whole topic and once again I thoroughly recommend his book which also critiques Phillip Johnson.

    Glenn, your post which carefully considered the distinction between the way we view the evidence for intelligent design or non-intelligent process was quite brilliant, and as you say, methodological science continues unaffected.

    The vision of ID is to allow scientists the freedom to consider whether material objects display intelligence in their design or whether they are products of pure naturalistic forces. Therefore, from an ID perspective, the natural vs. supernatural distinction is irrelevant. The real contrast is not between natural laws and miracles, but between undirected natural causes and intelligent ones.

    BTW, I’ll add Robert Pennock to my reading list, thank you.

    Before going on to Karl’s post, I would like to say that all bets are off. Yesterday I was given conclusive proof that intelligence and wisdom are behind the beauty of the universe. Ship Board has a new baby, I am now a father. My wife gave birth to a beautiful girl at 5:00pm yesterday afternoon, Singapore time. I was not going to post anything for a few days, but it’s the middle of the night and I can’t sleep because I’m still buzzing from the birth, so what else can I do?

    Karl, let’s go back to specification. You said

    quote:
    As for 'specified design' - well, yes. Of course.

    In light of what Glenn wrote and focusing on the concept of a specified universe, can you answer two questions for me?

    I’ll try to keep posting, but my frequency may decrease proportionately with my expected forthcoming lack of sleep.

    All the best

    Neil, before I start on the serious stuff, congratulations to you and your wife on the birth of your daughter.

    Now back to the scheduled programme ...

    quote:
    Originally posted by Neil Robbie:

    As a purely philosophical view I've no objection to that, but then that isn't different from other forms of theism which believes in design and uses the "design" within the material world in support of a philosophical position. However, if that philosophy position results in changes in science then I start getting worried. Those comments could just as readily be applied to philosophical materialistic atheism.

    Of course the philosophy of the scientist must affect the work done by individual scientists and the scientific community, but there are limits on how much philosophy affects the practice of science before the science itself is adversely affected. For example, I currently work in a branch of environmental science and my philosophical view that the evironment is the creation of God means I view what I do as being of greater importance and value than I might do if I was an atheist (not that I'm claiming atheists don't care about the environment, just that their reasons to care for it may be different from mine). Other scientists, because of philosophical views, may choose not to participate in experiments that involve animal testing; many nuclear scientists were actively involved in campaigning against nuclear weapons on the philosophical ground that they saw no reason they would ever be used.

    These are examples of how philosophical views of scientists affect why/what science they do. I happen to believe that ID, as I've heard it expressed as an alternative to methodological materialism, puts science into too tight a strait-jacket such that the resulting science isn't as good as methodological materialism.

    I've been away for a couple of days, and this thread has slipped to the second page of Purgatory for the first time!!!

    Karl, you’ve not answered my question about what you understand by the term ‘specified’, so I’ll attempt to do it for you.

    Firstly, however, we need to clear up the difference now between methodological science and the philosophy drawn from that science.

    When you said

    quote:
    Explanations that make no mention of, nor make any reference to, nor ascribe anything to, God, a god or gods. Or anything else supernatural.
    your statement was not clear as to whether the ‘explanations’ referred to functionality or origin.

    To clarify the difference between functionality and origin, let's take Behe’s examples of bacterial flagellum, the mammalian blood coagulation cascade or the biosynthesis of AMP (the first building block of DNA). The functionality of each of these examples is now understood, so the job of science is done in that regard. Having understood how these biological mechanisms work, science can now work on understanding diseases where these mechanisms are found to be involved.

    Can I assume that everyone agrees that understanding functionality and using that knowledge for the benefit of mankind is good science?

    Now, philosophically, there are two views of how bacterial flagellum, the mammalian blood coagulation cascade or the biosynthesis of AMP (the first building block of DNA) came into existence, philosophical materialism and philosophical theism. One says the bacterial flagellum, the mammalian blood coagulation cascade or the biosynthesis of AMP (the first building block of DNA) are products of a random, purposeless, material process, the other says that they are the product of intelligence.

    Is this still science? No, it is interpreting the results of science philosophically.

    Agreed?

    So, now we come to that word, ‘specified’ which you agreed with Karl. You see the universe as specified.

    I am an engineer, involved in building tall office buildings from steel. When we tender contracts, the consulting engineer supplies the information required in two forms

    So, specification is information. My Chambers Dictionary defines to specify as ‘to mention particularly, to make specific, to set down as required’.

    Now, we agree that the universe was specified, but you believe that explanations for good science

    quote:
    make no mention of, nor make any reference to, nor ascribe anything to, God, a god or gods. Or anything else supernatural

    As I outlined, working out how bacterial flagellum, the mammalian blood coagulation cascade or the biosynthesis of AMP (the first building block of DNA) function and applying that knowledge to practical applications is good science. Questions of God or the supernatural are not involved in this work of science.

    But, using science to justify a philosophical viewpoint is philosophy not science. Saying something is ‘specified’, and yet only subject to natural forces can be a philosophical viewpoint. But there is a flaw in this argument (if that is what you mean by specified but natural).

    This takes us back to Elliott Sober's METHINKITISAWEASEL and the flaw(s) in his argument.

    According to the theory of step-by-step development, DNA or AMP must have developed randomly and when a function develops which benefits the organism, the organism is able to reproduce more effectively and so the function is retained in the population. But, DNA sequencing is specific and without the full sequence of METHINKITISAWEASEL, we have no functionality. Even if only one letter was wrong in the sequence, it doesn’t function. If the sequence read METHINKITISAWABBIT, the functionality is completely different. If the sequence was MWTFIGKHTASDWQAVEM, every second letter is correct but it is meaningless and has no function.

    But, let’s say for this argument’s sake that somehow the genes did not require functionality as they assembled the correct sequence. Sober may well be right in his analogy that as the letters in the sequence stick in position, the genetic sequence could be assembled in 50 or 60 non-random attempts rather than being of negligible probability. The flaw is this, how do the letters know that they must stick in position? If they have no functionality, why don’t they just re-shuffle?

    Sober’s analogy concludes as Glenn pointed out

    quote:
    Although the analogy between this process and the mutation-selection process is not perfect in every respect, it does serve to illustrate an important feature of how evolution by natural selection proceeds. Variation is generated regardless of whether it "matches the target" (i.e. is advantageous to the organism). But retention (selection among the variants that arise) is another matter. Some variants have greater staying power than others.

    ... Variation is generated at random, but selection among variants is non-random.
    is really an analogy of specification.


    How do variants have ‘greater staying power’? How can selection among variants be non-random? How does a variant know when to stick and when to twist?

    Sober is in effect stating that variants show the properties of being specified. His flaw, from a philosophical materialist’s perspective is that there must be intelligence behind the specification.

    You said

    quote:

    Given what I clarified above about the distinction between to methodological materialism and ID (that ID is not an alternative, as the former is involved in functionality and the latter origin), the following ID statement shows how ID differs from creationism. In what way do you think the ID tenent is ‘too tight’?

    quote:

    Although intelligent design is compatible with many "creationist" perspectives, including scientific creationism, it is a distinct theoretical position. This can be seen by comparing the basic tenets of each view.
    Legally, scientific creationism is defined by the following six tenets:
    • The universe, energy and life were created from nothing.
    • Mutations and natural selection cannot bring about the development of all living things from a single organism.
    • "Created kinds" of plants and organism can vary only within fixed limits
    • Humans and apes have different ancestries.
    • Earth’s geology can be explained by catastrophism, primarily a worldwide flood
    • The earth is young—in the range of 10,000 years or so.

    Intelligent design, on the other hand, involves two basic assumptions:

    • Intelligent causes exist.
    • These causes can be empirically detected (by looking for specified complexity).

    Neil, you're making this far more complicated than I have time to go into. But, in brief...

    The simple fact is that both the origins you propose are in fact true:

    quote:
    Now, philosophically, there are two views of how bacterial flagellum, the mammalian blood coagulation cascade or the biosynthesis of AMP (the first building block of DNA) came into existence, philosophical materialism and philosophical theism. One says the bacterial flagellum, the mammalian blood coagulation cascade or the biosynthesis of AMP (the first building block of DNA) are products of a random, purposeless, material process, the other says that they are the product of intelligence.

    No! You persist in reading 'random, purposeless...' as a philosophical statement. It is not. It is a description of the process with respect to a scientific frame of reference. There is no purpose or direction within the sphere of science..

    So the first explanation is not philosophical, it is scientific. The two explanations are complementary.

    On to Sober's model - you are wrong in an important point. A protein can still be functional with a range of different sequences. A protein with one functionality can have other functions as a by-product, albeit inefficiently. This is enough for NS to work on. This has been demonstrated in the lab, and I will find the ref. for you if you want to see it.

    As I understand it, ID says that there are instances of mechanisms where the "scientific" explanation of their origin is that they are designed by an external intelligence. If I am correct in this understanding then ID is an alternative to to methodological materialism which explains the origins of these as variation on pre-existing mechanisms (which by definition had different functionality). When I say ID puts science in a tight strait jacket it is because if ID explains the origin of a mechanism that limits the investigation of what precurser mechanisms may have existed (since ID says they didn't exist). This in turn limits the scope of scientists to understand these mechanisms which could have implications for such things as drug design.

    Neil - More accurately, I mean "does it matter if the electron believes in God?" Or alternatively "Does it matter to the electron if YOU believe in God?" In either case, does the observer's theistic or atheistic belief have any effect whatsoever on the mass (or other physical properties) of the electron? I would say "no", that the believer and the infidel inhabit the same physical Universe with the same physical properties. A Christian doesn't have to make sure to buy their computer from the "theists only" section of the store for fear that the electrons will behave differently when they take it home. Idle speculation on hypotheses which cannot by their nature be tested experimentally fall outside the realm of legitimate science and are more akin to mediæval discussions about how many angels could dance on the head of a pin.

    Sorry, that was unfair. Mediæval philosophers didn't actually debate about how many angels could dance on the head of a pin. They worried about more important matters, like whether or not angels defecated.

    quote:
    ID puts science in a tight strait jacket it is because if ID explains the origin of a mechanism that limits the investigation of what precurser mechanisms may have existed (since ID says they didn't exist).

    But ID has not set out to limit the investigative nature of science. If a scientist is demotivated by ID, we need to ask why? Is it because, philosophically they were motivated by trying to justify a philosophical materialist's view of the world?

    If you would like a better clarification of this matter of motivation, you could try theAccess Research Network Webpage which has a helpful ID FAQ page (and an open discussion forum for those who like debating this sort of stuff with real scientists – which reminds me, we need to get back to the original point of this thread, which was the effect of all this on our theology or Christian practice).

    Karl, you said

    quote:
    No! You persist in reading 'random, purposeless...' as a philosophical statement. It is not

    But you said earlier

    quote:
    As for 'specified design' - well, yes. Of course.

    As an engineer, I see this as a philosophical oxymoron. Random, purposeless is a philosphical position. To keep it simple, here’s why.

    I’ve already defined specification. Some scientists refer to genetic blueprints, others now say they see specified complexity in organisms.

    If you believe, Karl, that the universe is specified good and well. If you believe that science is then restricted to random and purposeless, it contradicts the belief that the universe is specified.

    Let’s follow a simple example of a house. Once an architect and engineer draw the plans and specify the materials, how does the house get built?

    If it is random, material purposeless, the house will build itself from from the mud and straw it finds in the field where the house is to be built, the finished house will be nothing like the specification of the architect and engineer, because it is random and does not follow the specification.

    If, however, the house is built to the drawings, blueprints and specifications, the house will display evidence of intelligence and reflect the specifier’s requirements.

    As with all analogies, this has it’s weaknesses. I do not want to invoke the idea that there is a builder involved in the development of life (although there is a serious question about where the energy comes from which allows material to organise itself into living organisms), I merely want to illustrate that the process can not be random, material and purposeless if we believe that the information for life was specified. Belief in specification and a random process is an oxymoron.

    PS Cro?sos. Thanks for the clarification, we are all part of the same material universe. I was concerned you though it wasn’t important to consider the creator, which is in effect another aspect of our lives which is common to all.

    you say that:
    quote:
    I merely want to illustrate that the process can not be random, material and purposeless if we believe that the information for life was specified. Belief in specification and a random process is an oxymoron.

    But talking in such a way excludes a priori the possibility that God created the universe in such a way that life would naturally evolve. If he did so then by your definition we would have to say something like 'God intended us but did not design us.' Which given traditional ideas of the nature of God's foreknowledge is not necessarily a wrkable distinction.

    quote:
    Belief in specification and a random process is an oxymoron.

    No it is not, unless specification is defined so as to include design. Kenneth Miller in his book Finding Darwins God describes experiments by Barry Hall where Hall deleted the gene for a particular enzyme from a bacterium and then put it in conditions that would favour the survival of bacteria that evolved to have the missing enzyme again. Some did just that. It is of course possible to specify the structure and sequence of the gene and enzyme, but that is no indication that they specification was designed intelligently.

    Yes, that’s exactly what I meant. I didn’t want to speculate on how matter organised itself into living organisms, nor how long it took, but that the universe and everything in it displays the evidence of specification (everything from the precise constants of physics which allow the universe to exist, through the logic of all matter being the product of chemical reactions between 92 elements, to the carbon dioxide-oxygen cycle, to the functionality of complex organisms – there is evidence of engineering specification).

    I'm saying that, in broad terms, Paley was right and Dawkins is wrong. The watch has the appearance of being designed because it was designed.

    Put it this way, Dawkins and Paley express two alternative, diametrically opposed views:

    What you proposed was different to both those positions. Can you explain the logic by which you think

    quote:
    'God intended us but did not design us.'
    ? You seem to have excluded specification, in favour of random development, and in so doing you have excluded God.

    If "randomness and purposelessness" are a philosophical position, does that mean that quantum mechanics (as well as most of twentieth century thermodynamics) is an inherently unscientific field of study? Q-mech depends wholly on random, probabilistic behavior. Given the arguments about randomness presented here, I can only conclude that the theory of Intelligent Design must dismiss Q-mech as both unscientific and unGodly.

    Which brings me to my other point. The best, and indeed only, arguments I've seen presented thus far for ID are somewhat vague analogies. (Watchmaker, house, bridge, etc.) While analogies can be useful in clarifying or illustrating certain concepts, "reasoning by analogy" is almost an open invitation for fallacious conclusions. Is there any actual experimental evidence or direct observation or theorization involved here? If not, it falls outside the realm of science.

    Crœsos, "randomness" can be used scientifically (in, say the decay of radioactive elements) or philosophically (say, "the universe is a chance event"). As has been said several times on this thread about a range of things, the fact that randomness is a scientific term doesn't automatically mean the philosophical use of the term follows. Purpose (or otherwise) must surely be entirely philosophical.

    As far as ID is concerned my understanding (from the ARN website Neil mentioned earlier and the Origins website) is that ID stipulates there are a number of things (for example certain bio-chemical pathways) that are irreducibly complex, ie: if you remove any part of the mechanism it ceases to function. ID goes on to say that such mechanisms could not have developed gradually (at which point most scientists disagree, to say you can't go back is very different from not getting there in the first place) and therefore must have been formed by an intelligent designer. I view it as a philosophical position, and a weak one at that. I think I posted this link near the beginning of the thread, but I've given my views on ID on my website, and nothing in this thread has given me reason to re-evaluate those views.

    This is just one possible view but it goes like this: Suppose that God wished to create intelligent life and the method God chose to do this was to create a universe that naturally, and spontaneously, by evolutionary means resulted in life and eventually self conscious intelligent life.
    In such a case one could say that all God has specified are some basic fundamental laws of nature from which everything unfolds. It could be that there is genuine randomness involved in the process so that say it could have been a reptilian (or other) species that evoloved self consciousness or intelligence rather than a mammalian one. So in this scenario, by only specifying the initial conditions God left it to chance and natural selection to come up with us. Some people might then say that God intended self conscious intelligent life but did not design it. (The reason that I hesitate to affirm that distinction is that traditional views that God is omniscient make it difficult to say that his intention and his design are distinguishable. He would have known what would result in advance.)

    So in stating this view I have not excluded specification entirely but yes, chance plays a part. I have not thereby excluded God. However one result of this view would be that it would be impossible to demonstrate the existence of intelligently designed elements in biology.

    Your position in contrast would seem to be either that
    1) the existence of intelligently designed elements in biology is demonstrable; or
    2)that if God exists intelligently designed elements in biology
    must be demonstrable.

    I'm not sure which you hold, but I know of no convincing argument for (2).

    For your benefit, here's a little example for you to ponder from a philosophical materialist perspective.

    Miachel Behe asks the following question of philosophical materialism regarding the development of AMP:

    quote:
    The fact is that no one ever puts real chemical names on any of the mythical letters in the A-B-C-D story. In the textbooks mentioned above, the cartoon explanations are not developed any further, even though the books are used to teach PhD student who could easily follow detailed explanations. It is certainly no trouble to imagine that the primordial soup might have some C floating around which could easily be converted to D; Calvin and Hobbes could imagine that without any difficulty whatsoever. It is, however, much more difficult to believe there was much adenylosuccinate (intermediate XIII) to be converted to AMP. And it is even harder to believe that carboxyaminoimidazole ribotide (intermediate VIII) was sitting around waiting to be converted to 5-aminoimidazole-4-(N-succinylocarboxamide) ribotide (Intermediate IX). It is difficult to believe because, when you put real names on the chemicals, then you have to come up with a real chemical reaction that could make them. No one has done that.

    And please don't try top tell me that Allan Orr answered that question, because he didn't.

    As for QM, I've been following the other thread where this is discussed and am out of my depth. But let me ask you this? Could the laws of QM and thermo-dynamics have been specified?

    This might frustrate you and others on the thread, firstly because this is a bit of a moster post (sorry) and secondly because my philosophcial position has shifted in the process of this debate. I have found my philosophical attitude of any observable material phenomena is now neutral. You asked if my position was,

    quote:
    1) (that) the existence of intelligently designed elements in biology is demonstrable; or
    2)that if God exists intelligently designed elements in biology must be demonstrable.

    I have postulated the following position earlier on the thread, and now I am more convinced of the validity of this position. The position is not formed from the philosophical observation of scientific discoveries, like the AMP assembly described by Behe, the position is formed from a perspective of Biblical Theology. I believe that the application of Biblical Theology means that the results of scientific enquiry should not be used as evidence for any philosophical conclusion (atheistic or theistic).

    This view, I believe, will also help silence unscientific fundamentalists who insist on YECism. I have already discussed it in person with two YEC Christians in Singapore, who seemed to agree with this position.

    The position is this:that the existence or absence of intelligence is not demonstrable from elements in biology, and that this was the intentional position of God.

    We need to understand this position from a Biblical Theology of the cross of Christ and of faith in Christ. In Hebrews 11:1&2 the writer states this

    quote:
    'Now faith is being sure of what we hope for and certain of what we do not see. This is what the ancients were commended for.'

    In spite of the objectivity of the natural material phenomena observed by science, faith is what philosophical materialist (atheistic) scientists exercise when they postulate a universe without God, random and purposeless. They have not seen what they hope for (a universe without a God). They trust that God is not there by faith.

    But back to the letter to the Hebrews, the writer goes on to say

    quote:
    Hebrews 11:3 'By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible'.

    And so, likewise, scientists holding a philosophical theism (either ID or YECism) see natural material phenomena observed by science in their own philosophical light, and do so by faith.

    Out of context, those two quotes seem a very weak argument for my strongly held position, but taken in the context of the letter to the Hebrews, we can see the wisdom of this position.

    This is where YECism and Philosophical materialism (naturalism, atheism) come unstuck, and the YECs I mentioned agree.

    The letter to the Hebrews was written to a community of Jewish Christians who were losing sight of Jesus and drifting back to Old Covenant Temple worship, Jewish tradition and law. So, the writer was re-establishing Jesus as the fulfillment of Jewish law. The faith mentioned in Hebrews 11:3 is not blind faith or wishful thinking but faith in the resurrected Christ.

    quote:
    Hebrews 13:20 'the God of peace, who through the blood of the eternal covenant brought back from the dead our Lord Jesus
    .

    God's intention is for us to place our faith in Christ and in Christ alone.

    Observable material phenomena, whether biological systems, QM or thermo-dynamics are supposed to be a philosophical puzzle we can not solve, from a biblical perspective . YECism, in light of the cross is a distraction from faith in Christ. From a perspective of Biblical Theology, we will never be able to discern or disprove the existence of intelligently designed elements in biology or find demonstrable evidence for God in elements in biology, because God always wanted us to trust in Christ alone.

    Taking Galatians 2:15-16 slightly out of context (as it talks about justification by faith and not works) and inserting observation or material phenomena, we see that

    quote:
    "We…know that a man is not justified by observing the law (nor observing material phenomena by scientific enquiry), but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by observing the law (nor observing material phenomena by scientific enquiry), because by observing the law no one will be justified.

    It might not be the most mind blowing conclusion, it might even appear foolish to conclude the philosophical debate over the observable phenomena of nature from the cross, but I believe that the Bible is clear on this matter, that we are to have faith in Christ alone and we are not to have faith in Christ and the observable phenomena of material objects as the result of scientific enquiry.

    1 Corinthians 1:17-19

    quote:
    to preach the gospel - not with words of human wisdom, lest the cross of Christ be emptied of its power. For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. For it is written: "I will destroy the wisdom of the wise; the intelligence of the intelligent I will frustrate."

    Neil - I think you are confusing an indifference to the existence of God with the assertion of the non-existence of God. Science is heavily materialist in that it only concerns itself with phenomena that can be tested and experimented upon. As such, most people's definition of God falls outside the realm of science. What science does postulate is functional non-existence. In other words, the scientific position is that if something has no discernable influence on the experiment in question, its existence can be ignored. To provide you with an example, if it could be determined that atoms in a Universe with God would behave one way and that atoms in a Universe with no God would behave another, then the existence of God would be relevant to scientific inquiry. If, on the other hand, there is no "God constant" in atomic behavior, then the existence or non-existence of any sort of Deity is irrelevant as far as atomic science is concerned.

    Which brings us back to your position, which is that "that the existence or absence of intelligence is not demonstrable from elements in biology, and that this was the intentional position of God." If that is the case then your formulation of Intelligent Design is inherently unscientific (meaning "outside the realm of science"), unless you are postulating that ID is demonstrable through some scientific field of inquiry other than biology. Given this, it seems somewhat presumptuous for you to decry a scientific theory on what you seem to be admitting are unscientific grounds. The last time this sort of world-view prevailed was the Inquisition vs. Galileo.

    I'm still interested to know your thoughts on Michael Behe's comment on the development of AMP, but for now, I'll go on to your post.

    You clarified the work of science clearly with your definition of Functional non-existence. I think can offer another example, which I referred to earlier in this thread, the mammalian blood coagulation cascade. When mammalian skin is cut, it bleeds but the mammal is prevented from bleeding to death by the blood coagulation cascade. When we observe the healing of a wound, we witness functional non-existence. That is that God is not required in the event of blood coagulation because natural causes do the healing. The same can be said for a broken bone. God does not need to heal it miraculously, because natural causes do the healing.

    Now, taking your example of the atom and my example of the mammalian blood coagulation sequence or the broken bone, of course, we can observe, using scientific methods, the functionality of the objects and deduce that they work naturally, without need of supernatural intervention. As far as this, I agree with you.

    Now, l need to clarify your last paragraph. When you said,

    quote:
    If that is the case then your formulation of Intelligent Design is inherently unscientific (meaning "outside the realm of science").
    Yes, this is what I have been trying to say, that anything beyond functionality is into the realms of philosophy (atheist or theist).

    ID is not science, if science is described as observing the functionality of material objects. ID is a philosophy which states that material objects, in all fields of science, display 'specified complexity' as opposed to 'non-specified random complexity' and that some biological functions display 'irreducible complexity', like the AMP development sequence. This view is philosophical and can not be deduced by scientific measurement, experiment nor any other empirical means. But there again, the philosophical view that the universe and life is the product of a purposeless, random, material process can not be deduced by scientific measurement, experiment nor any other empirical means.

    And so I have concluded that, even with the brightest minds of the scientific community being applied to the philosophical question for almost 200 years, that the philosophical question of origin remains out of reach for mankind. From a perspective of Biblical Theology, this is the way God must have ordained it, because biblically, our faith in God is to be established in Christ alone. From a biblical perspective, God wishes the natural world to be silent on the matter of objective faith, because the objectivity for our faith is found in Christ's birth, life, teaching, fulfillment of OT law and prophecy, death, resurrection and ascension.

    In a way, you are right to say that

    quote:
    the last time this world view prevailed was the Inquisition vs Galileo
    At that time, Christian faith was dogmatic and fearful of science. However, another aspect of Biblical Theology is that God is always refining His church, and I believe that the issue of science has provided just such a refinement. The church is unlikely to ever burn scientific dissenters at the stake again, or behead them.

    But let's drag the argument out of the past and put aside the mistakes of the medieval church, let's look at the governing philosophy of the present day. On which side is the dogmatic fear today? Which cherished philosophical view is dominant today? It is the view that 'science' has proved that God is dead. Philosophical materialism (naturalism) has held dogmatically for the last 100 years to the claim that 'science' shows that everything we see around us it the product of a purposeless, impersonal, random, material process. Anyone who dares question this philosophical statement by attacking 'science' is seen as a heretic, a dissenter and is dealt with severely, chastised and persecuted, not with fire but a lashing of the tongue.

    The paradigm shift has started to swing against philosophical materialism and the result will be the dismantling secular humanism and all the systems which support it. If 'science' does not support an atheist philosophy then the morals, ethics and laws of relativism have no basis and should not be taught exclusively in schools nor be practiced exclusively in courts of law or government. The 'culture wars' are about to get interesting.

    I am tempted to conclude that there is no coincidence between your new thread

However I would not be at all surprised if there is a posting in this thread of yours that says we can't pick and choose scripture which finally triggered it off!

    I am now half way through Behe's Darwin's Black box and am reading Miller's Finding Darwin's God too plus Mark Ridley's Mendel's Demon. Will let you know my responses shortly. This thread of yours has cost me an arm and a leg in book purchasing.

    Posted by Crœsos (# 238) on :
     
    Neil - As you may have guessed, my background is in physics, so my critique of your Behe quote is proceding slowly due to the need for some refresher research. It's been years since I had to deal with biochem. But rest assured I will eventually post a response.

    The rest of your post seems convoluted and self-contradictory. For starters, your definition of science is only partially complete. A more complete definition would be that science is described as observing the functionality of material objects and drawing conclusions from those observations. A very simple, and relatively famous, example involving the previously mentioned Galileo would be his experiments with gravity. Galileo observed that the variously sized and weighted balls he used in his experiments fell at the same rate. The observations are that "these specific balls fall at the same rate when subjected to gravity". The conclusion drawn was "all objects are moved in the same manner by gravity, regardless of weight". The drawing of conclusions, the formulation of the general case from the specific instances, is probably the most critical step in the scientific process.

    Which brings us to the contradiction. You stated that

    quote:
    ID is a philosophy which states that material objects, in all fields of science, display 'specified complexity' as opposed to 'non-specified random complexity' and that some biological functions display irreducible complexity', like the AMP development sequence.

    In other words, you are observing "material objects" ("in all fields of science", no less!) and then drawing conclusions. This means your definition of ID falls withing the purview of science, and should then be subjected to examination, experimentation, and confirmation or disproof. But then in the very next sentence you state that

    quote:
    This view is philosophical and can not be deduced by scientific measurement, experiment nor any other empirical means.

    Given your assertion that this philosophy cannot apparently be deduced or in any way measured materially, I have to wonder how this conclusion, which seens to deal exclusively with material phenomena, was reached. Your argument in favor of it, minus the material arguments you admit are irrelevant and unconvincing, seems to amount to "it must be true because I believe it".

    As far as science "chastising and persecuting" dissenters, another important characteristic of the scientific process is the debate between various alternative theories. These debates can be quite vigorous, and since science is a materialist pursuit, theories which "can not be deduced by scientific measurement, experiment nor any other empirical means" are soundly and rightly "chastised" as unscientific. Quite frankly, I'm not sure that verbal criticism of one's position can really qualify as "persecution".
     


    Posted by Crœsos (# 238) on :
     
    As far as the question of whether the laws of Quantum Mechanics or Statistical Thermodynamics could have been specified, I don't really see a way it could be done without postulating some sort of supernatural factor, and as previously stated the supernatural falls outside the purview of science. From a scientific perspective, such formulations fall within the "Angels and Pinheads" speculation mentioned above. In order for an hypothesis to be considered by science, some method of testing its validity must be available, something more concrete than simply saying, "Well, it might be true."

    Okay, let's take your wider definition of science, which is

    quote:
    science is described as observing the functionality of material objects and drawing conclusions from those observations

    Your example of Galileo's gravity acting on objects, which was famously demonstrated with a hammer and feather on the moon, is a good example of your continued confusion between material scientific conclusions and philosophical scientific conclusions.

    So let's use this example to separate science from philosophy.

    Galileo concluded that all objects move in the same manner by gravity, regardless of weight. That is a scientific conclusion.

    Galileo is not only famous for his scientific experiments and scientific conclusions. When Galileo declared the Copernican doctrine as scientific truth (which Copernicus had already established), he was found guilty of blasphemy by a mediaeval church which held a theologised version of the unscientific Ptolemaic theory of the universe as a core doctrine.

    Galileo's confirmation that Copernicus was right is a scientific conclusion, and the church was wrong to hold dogmatically to an earlier and erroneous scientific theory.

    In 1898 Andrew Dickson White, who was Professor of History at Cornell University wrote a two volume tome called 'A History of the warfare between science and theology in Christendom' in his concluding chapter he writes:

    quote:
    If, then, modern science in general has acted powerfully to dissolve away the theories and dogmas of the older theologic interpretation, it has also been active in a reconstruction and recrystallization of truth; and very powerful in this reconstruction have been the evolution doctrines which have grown out of the thought and work of men like Darwin and Spencer.

    And that is what we have all, a century later, come to take as the truth, that science has disproved theology. But it has not. It has disproved 'theologic interpretation' of erroneous scientific theories.

    Concluding that gravity effects all objects in the same manner and that the world spins around the sun says nothing about God. God could have specified gravity and planetary motion (and QM and the laws of thermodynamics). However, most people today disregard God, the Bible, Christ and His Church because they think that the doctrine and theology of Christendom had something to say about gravity of the rotation of the earth (loosely seen as the Genesis account of creation) and because it was wrong everything in the Bible must be wrong. But, we need to make the distinction between what the church believed and what the Bible said. The unscientific Ptolemaic theory of the universe is not in the Bible even though some theologians, even Luther, found scriptural reasons to believe this 'scientific' conclusion. This is bad theology, as well as bad science.

    As I said near the start of this thread, the Genesis account of creation answers the who made it and why was it made questions, not the when was it made and how does it work.

    Just as it was wrong for the church to adopt the Ptolemaic theory as scriptural, it is wrong for scripture to be applied to any scientific theories, because, as I said, we are all to trust in Christ alone and not Christ and observations of material objects. YECism, ID and philosophical materialism fall down as belief or faith systems on this simple Biblical truth.

    But is it equally wrong to think that the discoveries of the action of gravity and the fact that the sun moves around the sun, or any other observations of science disprove God. This muddled thinking dominates western culture today, because no distinction is made between your example of 'scientific conclusion' and 'philosophical conclusion derived from a scientific conclusion'. There is no distinction made because one word is used to describe both kinds of conclusion. That word is 'science'.

The title of his work says it all, he had a pet theory about theology being at odds with science and went out of his way to find examples of theology objecting to scientific discoveries totally ignoring anything that disagreed with his view. It is, put simply, a very bad piece of historical research.

    Ah.

    Many thanks Alan…I'll try to check the background to my references in the future.

    Regardless of Dickson White's philosophical bias or his biased historical account, the point remains that 'scientific conclusions' must be categorised as either functional or philosophical conclusions.

    Crœsos used a functional conclusion to challenge a philosophical conclusion, but the two conclusions are mutually exclusive.

    Would you agree?

    Neil
     


    Posted by Alan Cresswell (# 31) on :
     
    Neil, just trying to understand where the problem arises.

    Crœsos uses Galileos' experiment with dropping different mass spheres to demonstrate the way science works, at no point is the conclusion ("all objects are moved in the same manner by gravity, regardless of weight") philosophical. Except, science has, naturally, a philosophical basis - that the universe behaves in an orderly, predictable and comprehensible manner; one consequence of which is that it is reasonable to say that on the basis of a set of observations predictions about the behaviour of the physical universe can be made whether or not specific measurements are made.

    Where ID and YEC differ from science is that underlying philosophical underpinning; both assume there may have been discontinuities in the orderly and predictable nature of the universe when God acted outside those bounds in a miraculous way, and that it is reasonable to assume that "science" will be able to observe the consequencies of such intervention. (I happen to believe that God has performed miraculous acts, but I don't expect there to be scientifically observable consequencies of such miracles)

    I agree that reading "science" from Scripture is bad theology. I agree with your last 2 sentences too, with one amendment, I would say "There is no distinction made because one word is mistakenly used to describe both kinds of conclusion. That word is 'science'." That mistake is made by two different groups of people, the general public who generally don't recognise the distinction and a small group of scientific atheists who recognising the confusion in the thinking of the general public cynically use that to their own ends (ie: "science disproves God").

    I gather from what you said

    quote:

    that you understand ID to involve miracles.

    When you use the word science, it has the dual meaning we discussed. You have used it in the sense of empirical research into material function. I have tried to identify that role of science as a stand-alone activity.

    That then leaves us with the other activity of philosophical conclusions which are drawn from science.

    I, like you, believe that God has performed miraculously, the greatest miracle being Christ’s resurrection. But I do not wish to confuse occasional miracles with the question of origin.

    The ID philosophy given on the Access Research Network Webpage states this quite clearly.

    quote:
    From an ID perspective, the natural vs. supernatural distinction is irrelevant. The real contrast is not between natural laws and miracles, but between undirected natural causes and intelligent ones.

    The big picture difference between philosophical conclusions drawn for material conclusions is that ‘science’ in it’s philosophical sense, says that there is no intelligence behind the universe, whereas ID says that there is intelligence.

    In short, ID says:

     Intelligent causes exist.
     These causes can be empirically detected (by looking for specified complexity).

    And philosophical materialism says:

     No intelligent causes exist, that everything is random and purposeless.
     That material causes can be implied because God is beyond the knowledge of materialism.

    Now, this has huge implications for post modernism, because modernism starts with the latter philosophical conclusion and permits subjective religious experience as a product of materialism (ie that God is a product of human imagination).

    Challenging the philosophical materialist conclusions of science, not the scientific conclusions themselves, is to challenge the very foundation of post modernism and western culture.

    Going back to the blood coagulation cascade, ID does not challenge the scientific conclusion, the functionality is plain for all to see. ID challenges the philosophical conclusion that blood coagulation is the product of non-intelligent causes. ID does this by postulating that intelligent causes produced the design and specification, the blueprints and process diagrams.

    How material was assembled to fit this specification does not end with the answer, ‘it was a miracle’, it ends with the answer ‘the materials were always going to assemble this way, because that is the way they were designed’.

    This theory does not postulate 'discontinuities in the orderly and predictable nature of the universe' (miracles) rather that the universe is orderly and predictable in nature because it comes under the unified theory of specification, design.

    Neil, I'd forgotten that the ID sites I know of all insist they're not saying God acted in a miraculous way (it often seems to be part of their response to "ID is YEC" claims). However, the impression I have from my reading (perhaps if I get some time I might read Behe), mostly websites, and what you just posted is that ID claims that there are instances of irreducible specified complexity which science will show could not have been formed by purely material processes; well in my book anything not the result of purely natural processes is a miracle.

    quote:

    hmm, a bit stronger on the design than I would go personally. I would say that the orderly, predictable nature of the universe is a result of the nature of the Creator (which is one point where theism is simpler than atheism). I'm not sure about a specified design though.

    Have you ever come across Polkinhornes' concept of free process? He postulates that God gave the physical universe the freedom to develop through God given process however it "wishes" (not that the universe has a consciousness to wish anything) while still being under the sovereign will of God. It is a variation on the free will/sovereignty of God dialectic.

    Alan - The idea that the Universe behaves in an orderly, predictable, and comprehensible manner has been borne out repeatedly by our experience and experiments. I went into considerable length about some of the results of materialist inquiry way back on page in my posting of 30 July 2001 02:50. Given the overwhelming success of inquiries founded on this premise, I expect you to come up with something truly spectacular to refute it.

    Neil - You seem to want to have it both ways.

    quote:
    • Intelligent causes exist.
    • These causes can be empirically detected (by looking for specified complexity).

    It's your second postulate that gets you into trouble. By stating that "these causes can be empirically detected", you have placed your theory of Intelligent Design within the realm of science, not philosophy. As a parallel example, I could state that:

    • Electrons exist.
    • Electrons can be empirically detected.

    Does that mean that electrons are beyond the understanding of science and are instead philosophical constructs? Obviously not. Anything which can be empirically observed can be examined by a scientific, materialist process. It's somewhat frustrating to me that you keep making this apparently fallacious assertion, that I keep pointing it out, and that you don't seem to take any effort to resolve this apparent paradox.

    I'm not going to refute it, in fact it's a premise I've always accepted (and if I've given the impression that I don't I'm sorry if I've confused anyone). My point is that it is a premise, and no amount of data in support of it is actually a formal scientific proof of the premise. My other point was that it is a premise that could be expected from a theist philosophy.

    Alan - Every time we demonstrate that the Universe behaves in thus-and-such a manner, it is one more piece of evidence in favor of an orderly Universe. For example, if we determine the way gravity behaves, that is one type of order. If we demostrate that the atom has a certain structure to it, that is another type of order. Both of these, and countless others, constitute a large data set in favor of the orderly Universe proposition. I'm not sure exactly what you would consider a "formal scientific proof" of this proposition. In other words, if we can comprehend that the Universe behave in an orderly fashion which can be predicted by science, does this not mean that the Universe behaves in an "orderly, predictable, and comprehensible manner"?
     
    Posted by Alan Cresswell (# 31) on :
     
    Crœsos, what I'm trying to say is that the orderliness of the universe is axiomatic for science to function. That scientists constantly add to the body of knowledge built on that axiom doesn't mean it's no longer axiomatic. Scientists set out assuming that things are ordered and predictable, and when they don't seem to be go back and reanalyse the data or reformulate theories until things are orderly and predictable. To say that having done that the order and predictablity of the universe is proved by the order and predictability of the body of scientific knowledge is a circular argument. Which is why I say it can't be proved by formal scientific means.

    Is this making sense?

    We are caught in the ‘scientific’ word puzzle again, sorry for causing you frustration, please continue to bear with me as we work this one through, and thank you for your patience.

    I do not see my statement

    quote:
    These causes can be empirically detected
    as material ‘scientific conclusions’ but as philosophical conclusions drawn from empirical scientific conclusions.

    The important word is not empirical, but detected.

    Taking your electron example.

    I find it helpful to remember in this example that it is people who do the detecting, scientists are material detectives. It is their individual and corporate philosophy through which they look at the empirical conclusions and draw their own philosophical conclusions.

    Alan - I'm afraid that doesn't make a lot of sense, at least to me. What you seem to be indicating is that any order or organization within the Universe is a philosophical construct and not a physical reality. Let's say I take hold of a pen on my desk, lift it, and drop it to the floor. I notice that it fall down. I repeat the experiment. And again. I do this fifty times and each time the pen plummets to the floor. Is it unreasonable to conclude that on the fifty-first time the pen will also fall to the floor? Or would it be more reasonable to state, as you seem to suggest, that nothing about the pen's actions when dropped can be anticipated in advance since that would imply some sort of predictable order in the Universe? If being able to demonstrate an orderly pattern in at least some portions of the Universe is not an indication that the Universe is at least in some way orderly and predictable, the what would you consider to be suitable proof?

    Neil - You seem to be either unfamiliar with the word "empirical" or are simply regretting using it. "Empirical" means relying on experimentation or sensory data rather than theoretical or systematic knowledge. Thus, when you say that something can be "empirically detected", it is natural for me (or anyone else who knows what "empirical" means) to conclude that you mean that there are some sorts of physical measurements or material data which support your formulation of Intelligent Design. Further, I'm not even sure you're that clear on the meaning of the word "detected", which is usually applied to the discernment of physical phenomena. "Detected" is usually also taken to imply that the thing being detected has some sort of existence independent of the detector, something which is not at all apparent about philosophical conclusions. Most philosophies are said to be "deduced", not "detected". Of course, "deduced" is probably too strong a word to use in this instance, since most deductions, in the typical sense of the word, are the result of reasoning and evidence which lends a comfortable degree of certitude that the conclusion reached is the correct one. When there is insufficient, unclear, or even contradictory evidence so that multiple contradictory conclusions can be reached, the proper term is "speculate", not "deduce" or "detect".

    Crœsos, I'm not saying that the order in the universe is a philosophical construct, I believe it is a genuine feature of physical reality which is why science has been so successful by assuming this. What I am saying is that the expectation of orderliness is a philosophical construct which IMO is best explained by theism; I can't think of any explanation from pure materialistic philosophies except that it simply is orderly and predictable, more scientific data demonstrating the orderliness of the universe does nothing to explain why it's orderly.

    You have managed to avoid the point I am trying to make by turning the argument against ID for implying that intelligent causes can be 'empirically detected' and you say that this claim is unscientific.

    As you are aware, I am more interested in attacking the philosophical legitimacy of 'science', for the reasons I explained from a Biblical Theology of the Cross of Christ. So, please allow me to ask you this question. You said

    quote:

Of course, "deduced" is probably too strong a word to use in this instance, since most deductions, in the typical sense of the word, are the result of reasoning and evidence which lends a comfortable degree of certitude that the conclusion reached is the correct one.

    I say that from a perspective of sound Biblical Theology and well informed scientific reason, it is legitimate to adopt the philosophy that the universe is indeed the product of intelligence.

    Accepting your interpretation of the words 'empirical' and 'detected' (which I see as a semantic difference and which does not detract from my point - that 'science' can make no legitimate philosophical claims), can you tell me, using your definitions of these words, on what basis science can legitimately make the philosophical claim that the universe just is…that there is no intelligence behind the orderliness of creation?

    My apologies for crashing in so late on this thread- a little later than I would have wished as I actually read the whole thing from start to here, so my post is full of disembodied bits and pieces that occurred to me while reading the interesting debate. Please forgive me if I'm offering simplistic comments.

    1) First up, this quote:

    "Yes, that’s exactly what I meant. I didn’t want to speculate on how matter organised itself into living organisms, nor how long it took, but that the universe and everything in it displays the evidence of specification (everything from the precise constants of physics which allow the universe to exist, through the logic of all matter being the product of chemical reactions between 92 elements, to the carbon dioxide-oxygen cycle, to the functionality of complex organisms – there is evidence of engineering specification)."

    Surely only points to a way of percieving the world, i.e. one sees the specification where it may or may not be there because of one's own pre-existent expectations and paradigms, taken to its silly extreme, rather like the incidences of Jesus' face appearing on a tortilla etc.


    2) Lots of suggestions that philosophy and science are mutually exclusive. I was always under the impression that philosophy
    was the original and purest form of science.


    3) The assumption that 'Darwinism' has led to a loss in belief which in turn has lead to a decline in Christianity implies very much that the belief was there in the first place even when 'active' Christian numbers were much bigger and I would dispute that on a variety of historical grounds, such as a) dropping Christian activity prior to Darwin and b) a steady decline in the 20th century rather than a preciptous drop.

    4) There was a mention of evolution theorists being 'split' into gradualists and 'crisi' types. I see no reason for the two schools to be mutually exclusive as clearly they are not.

    5) The idea that God can be proved OR disproved by scientific method is patently silly, as He is outside the created order. This goes for both the more fundamentalist Christians and the more fundamentalist scientists.

    6) Young Earthers. Oh dear. I didn't realise quite how silly things are getting over in Fundamentalist land.

    First it appears that the Creationist method is to 'disprove' evolution. Even if this were possible, the question would be- and? Disproving the 'evolutionist' account obviously does not prove the 'creationist' one. We are, however, from all evidence as far away as it is possible to be from Creationists offering any worthwile evidence so no worries there.

    But more importantly, surely, seeking to 'prove' the scientific validity of the Genesis account is missing the point big time, in the same way as 'biblical archaeology' or all those ingenious arguments designed to show how, for example, the plagues could have occurred through volcanoes etc. God does not need proof. If the entire Old Testament were shown to be non-historical and scientifically impossible it would make no difference.

    Just my two penneth worth

    Welcome St Rumwald

    Your contribution is welcome at any time, and it is refreshing to have a new voice in this discussion.

    I would like to pick up on a few things you said.

    In broad terms, this thread is not about creationism. It is not about justifying the Genesis 1-2 account of creation (I believe that the world is 4.6 billion years old, because science has observed it). Primarily, the thread is about the effect of a shifting philosophy of the observed world on theology, but at present we are still debating whether that philosophical shift is taking place.

    To help me clarify this, you said:

    quote:
    Surely [ID] only points to a way of perceiving the world, i.e. one sees the specification where it may or may not be there because of one's own pre-existent expectations and paradigms

    Yes, indeed. In fact every since humans started investigating the world around them (detailed astronomical observation was recorded by ancient Babylonians and the ancient Greeks had theories on the structure of matter) we have been matching those observations to our pre-existent expectations and philosophical paradigms.

    This was the mistake of the medieval Church, it adopted erroneous observations of the world as doctrine. It is also, surprisingly, true of YECism, which does the process in reverse by adopting erroneous observations of the world (I am reading ‘The Early Earth’ by John C Whitcomb which is scientific tish-and-pish) because of their prior commitment to a literal reading of Scripture.

    From a Christian perspective, one of a Biblical Theology of Salvation by Christ alone, I have pointed out that Christians do well do avoid adopting a strong belief of the how and when questions regarding God’s created the world.

    But at present on this thread, my issue is to help atheists and agnostics see that their observations of the world around them can not be detected in science but are deduced from their own pre-existent expectations and paradigms.

    The only logical answer Crœsos can give to my question is that is it a pre-existent expectation and naturalistic paradigm which states that the world just is…that it is not the product of intelligence but that the universe just exists because it just exists…and that the empirical conclusions of science are interpreted under this paradigm (I know, because I lived under this paradigm until 1993)

    Francis Bacon was instrumental in freeing science from medieval superstition and philosophy, but science is now bound by an equally dogmatic philosophy which emerged at the Enlightenment and reached its natural conclusion when Neitzche pronounced that ‘God is dead’ towards the end of the nineteenth century.

    So, science is never independent of philosophical paradigms, humans will always try to understand the world in light of their own pre-existent expectations and paradigms. I am speculating that we are now moving from post-modernism to a new paradigm. The modernism or philosophical naturalism of the mid-twentieth century gave way to post-modernism when people began to hunger for spirituality. That spirituality has left people hungering for something more than a subjective experience of religion, as the paradigm shifts, people are beginning to view the world around them as designed. If empirical conclusions support a ‘design’ philosophy then the paradigm shift will gain momentum.

    The ID movement says that empirical conclusions can support philosophical conclusions of design.

    I am excited by this potential paradigm shift, because the philosophical landscape will be much different in ten years time and we don’t know what it will look like yet. I still hope we can discuss, on this thread, the potential outcome for theology.

    Alan - I would argue that scientific inquiry does not blindly or arbitrarily assume or expect order, but is rather the logical outgrowth of the observation that certain physical phenomena behave in an orderly fashion. If science behaved as you seem to suggest by pre-assuming order or pattern, it would be unable to determine when a theory is fallacious and no pattern exists. For example, astrology claims to represent an ordered, predictive system, and yet mainstrean science has rejected its legitimacy. How is that possible for a system that pre-assumes the validity of order?

    Neil - I never said that your claims of empirically detectable intelligent design were "unscientific". On the contrary, I have repeatedly pointed out that any claims of an empirical nature fall within the realm of scientific inquiry. What I have objected to is your statement that this is a philosophical position not subject to material verification, which would make your position unscientific. These are contradictory positions and cannot BOTH be correct. And though your claim of intelligent design is indeed of a scientific nature, your repeated failure to posit a possible test of this hypothesis leads to the conclusion that you don't have the data to back up your assertion. Perhaps you can clear this up once and for all. Is Intelligent Design verifiable through scientific measurement?

    As for claims "that there is no intelligence behind the orderliness of creation", I have never advanced such a claim. As for how science in general can make such a claim, science is not so definitive about the matter and doesn't state things so strongly. The strongest statement of this nature goes back to the premise of functional non-existence, referred to in my post of 06 August 2001 23:22 back on page 11. If you can't pony up some evidence to back your hypothesis or conceive of a way in which its truth or falsity could affect scientific measurements, then for the purposes of science whatever it is you are postulating might as well be non-existent.

    Crœsos, I'm afraid I've been using "ordered" as a shorthand for things like order, predictability, comprehensibility, mutual compatability (discoveries in one field of science not contradicting, often complimenting, other fields) and internal consistancy. There are probably other things we could add to that list. Because I'm not typing that lot every time, take it as read that I'm using that shorthand in refering to order in the universe.

    Many early scientists studied such things as astrology and alchemy; however they were eventually shown to not be as ordered as astronomy and chemistry, and were relegated first to pseudo-science and later superstition on the basis that they didn't work.

    I would say again, science works because the universe is ordered. It is also very likely that the reason modern science developed in Christian (and to a lesser extent Islamic) societies is that theism results in an expectation of order. If you were in a society which, say, put everything down to the actions of a pantheon of capricious gods then the incentive to go and look for order in the way things work wouldn't be there since you wouldn't expect there to be any order.

    My point is that in moving away from theistic to atheistic philosophies the basis for a belief that the universe is ordered is lost, to be replaced by what is essentially mere pragmatism (assuming the universe is ordered works).

    Let me try to capture both my understanding of scientific investigation and the philosophy which derives from it by quoting from Kirsten Birkett’s (BSc, PhD) book, ‘Unnatural Enemies, an introduction to science and Christianity’.

    quote:
    Naturalism is a belief (my emphasis added) that only natural laws and forces work in the world…Since the eighteenth century, this view has grown in popularity…The public assumption of (belief in) naturalism has been greatly bolstered by twentieth century scientific discoveries. It has grown to be a grandiose view…The Theory of Everything.

    On a rather more limited basis, science has, in practice, traditionally assumed naturalism as a working hypothesis ‘in the lab’…In the writings of Francis Bacon, and the early discussion of the Royal Society, we find an agreement to leave theology outside the laboratory…this was not a basis for atheism…Francis Bacon, and most of the members of the Royal Society, considered themselves devout Christians (I add- remember the governing paradigm of the seventeenth century was Reformation Theology).


    You said

    quote:
    I have repeatedly pointed out that any claims of an empirical nature fall within the realm of scientific inquiry.

    Francis Bacon would agree with you. What he would not agree with is bringing theology into the laboratory, be that theism or atheism. In other words, we can work out how things work in the lab without asking why they work (God made them or God didn't make them).

    That is the point I am trying to make. I do not wish to consider the ‘rather more limited basis’ of assuming naturalism in the lab, that’s fine by me. It is the grand vision of a Theory of Everything, which is a philosophical position excluding God, and which most people take for granted in public life, that I would like divorce from science. It is not science to exclude, disprove or discredit God, that is philosophy.

    You define yourself as an atheist in your profile. I am genuinely interested, in light of our discussion about naturalism, in the basis for your atheistic philosophy. Can you explain on what grounds do you believe that there is no God and that the universe ‘just is’?

    We're now on post 286 and much has been discussed from many different angles. No one has discussed the effects of naturalism, philosophical materialism, on our theology. It is clear, however, that not only has philosophical materialism polluted Christian thinking but that the issue is so complex that many of us are unable to 'think outside the box', that is to remove ourselves from the philosophical paradigm of the late twentieth century and challenge ourselves on what we believe.

    This inability to think outside the box is due, IMHO, to the complexity of the relationship between science, culture and theology. It is because the place of science in society and its effects on culture are not defined by a single simple relationship, but a very complex and multi-facetted one. There are many interwoven and interacting aspects of the relationship of science with society, and they have all been addressed at some point on this thread.

    I would like to try to summarise some of these issues. This list is not exhaustive, but it demonstrates the complexity of the argument which each of us needs to appreciate if we are to understand the effect of the philosophy that governs science and corrupts much Christian theology.

    hasn't it been a large part of this thread that philosophical materialism hasn't "polluted" Christian thinking. Certainly it's influenced Christian thinking, but since it's a major philosophical position it needs at least a response from Christian thinkers. While we're on the subject, philosophical materialism is hardly unique in influencing Christian thought; neo-Platonism was a major influence on early Christian thought, Zoroastrian dualism appears to have influenced Jewish thought during and after the Exile, to give just a couple of examples. Christian thinkers are influenced by philosophies influential in the cultures they find themselves in, and often their thinking is enriched by what those philosophies have to teach us.

    Which brings us to one of the points on your list,

    quote:
    • We need to understand that theistic evolution is another philosophical position which attempts to marry the theory of evolution (random, purposeless and material) with theology (a specified and created universe).

    I tend to prefer the term "theistic materialism" to "theistic evolution" since my (admittedly philosophical) view of the relationship between God and the material universe encompasses far more than biological evolution. "Materialism" because I believe that methodological materialism (ie: science) is more than adequate in providing answers to questions of mechanism in the physical universe (including the mechanism of origins). "Theistic" because I believe there are questions about purpose, and why methodological materialism does work, that can best be answered from a (Christian) theistic viewpoint. The theistic and materialistic are complementary, the whole being greater than the parts, views of the same reality.

    Now for a fairly light hearted illustration of complementary views:

    Sherlock Holmes and Dr Watson were camping. Holmes awakes during the night, and shakes Watson awake. "Watson," he asks, "what do you see?"

    "Lots of stars", Watson answers. "What does this tell you?" asks Holmes

    "Well", replies Watson, "astronomically speaking that there are countless millions of stars and galaxies, doubtless orbitted by countless millions of planets. Horologically speaking that it is shortly after 3 in the morning. Meteorologically speaking I reckon it'll be a wonderful day tomorrow. Tell me Holmes, what does it tell you?"

    Holmes is silent for a while, then replies "Elementary my dear Watson, it tells me that someone has stolen our tent"

    Neil - You seem to know (or at least assume) a lot about my personal beliefs based on a one-word description in my profile. As far as my non-belief in God goes, it is simply a result of my never having needed to hypothesize a Deity. As far as the theory that the Universe "just is" goes, you seem eager for me to assert something of that nature, this being the second time you've placed those words in my mouth, but I wouldn't go so far. At the moment, my strongest assertion along those lines are that the Universe "is". As far as theories of causality go, yours is the one currently under discussion, having been the basis of this whole thread. A more cynical person than myself might think you were trying to direct attention away from the inconsistencies in your theory by changing the subject, but I would never accuse you of such.

    I assume that once again you are using scientific terms out of context, though since Kirsten Birkett has a Ph.D. I'm not sure the same can be said of her (his?) book. The "Theory of Everything" usually refers to a theory unifying the three particular forces (strong, weak, and electromagnetic) with gravity. I take it that this is not your meaning and that your theology bears no more animosity towards particle physics than it does any other branch of science. At least, that is the "Theory of Everything" I am most familiar with. What you seem to be objecting to is the philosophical assertion that science can explain all material phenomena. While I would not be so grandiose in my claims, not being familiar with all material phenomena, I would say that thus far science has done a lot better job of explaining the material Universe than any theological formulation. So getting down to specifics, which material phenomena do you believe are outside the realm of scientific inquiry? So far the list seems to include molecular biology and speciation. Are there others? And how do you decide what's on the forbidden list and what's okay for science to investigate?

    You also said that "It is not science to exclude, disprove or discredit God". Actually, it is science to exclude God. By its nature, science does not include supernatural or unnatural phenomena, such as a Deity. As for "disproving" or "discreting" God, that would only become an issue if your formulation of God was subject to material verification.

    Your longer list post has some interesting points some of which I'd like to touch on. For instance, you stated:

    quote:
    We need to openly admit that 'the theory of everything' is not a theory waiting to be proved by empirical evidence, but that it is a materialist philosophy which has developed highly speculative 'scientific' theories like 'imaginary' time to justify itself.

    The existence of imaginary time is strongly suggested by Special Relativity, particularly the Lorentz transformations. Do you reject relativity, or is there a more specific cause of your objection to imaginary time?

    quote:
    We must admit that there is no empirical proof for any of the philosophies outlined above, only deductions made by humans from the material evidence.

    . . .

    Under a unified theory of specification, sense can be made of all empirical material evidence just as a unified theory of random chance has sought to unify all empirical material evidence.


    This seems like you're still trying to have it both ways. Either your theory of specification or intelligent design or whatever you're calling it this time is subject to material verification or it isn't. Could you make up your mind and let us know which it is?

    By defending the ‘enrichment’ of Christian thinking by philosophical materialism rather than admitting its pollution, you are stating a subjective position based on what you believe to be ‘enrichment’. I'm sorry, but this is going to be another lengthy missive.

    Your argument that neo-Platonism (a system of idealistic, spiritualistic pagan polytheistic philosophy, which tended towards mysticism and which flourished in the pagan world of Greece and Rome during the first centuries of the Christian era) and Zoroastrian dualism both influenced Christian thinking helps demonstrate my point. The former post-dated Christ, the latter pre-dated Moses. The latter may have been influential in shaping early Biblical manuscripts, but the latter is a reaction to Christian doctrine. Philosophical materialism is, in much the same way as neo-Platonism was, an intellectual reaction to the success of Christian doctrine (post Reformation).

    Recent external influences, which you see as a positive enrichment, are nothing more, IMHO, than post-scriptural influences on Christian doctrine and are pollutionist, not adding anything to the divine plan of redemption in Christ revealed in scripture.

    Focusing only on theology developed during the post-enlightenment period (which is the particular period this thread is concerned with and the period from which secular humanism emerged as the governing western philosophy and to which the liberal church tried (unsuccessfully) to adapt Christian theology to suit) we can trace the seepage of pollution into Christian thought:

    My argument is that philosophical materialism and, most prominently, Darwinian theory and its derivatives support secular humanism and liberal theology. If Darwinian theory is relegated from a position of supremacy amongst biologists to only one of a number of competing theories as to the development of life, the ‘Darwinian’ post-Enlightenment rationalism, philosophical materialism, will be relegated with it to one of a number of competing sources for truth. This is post-post modernism or realism.

    You are entitled to a theistic materialism, but I believe that if you promote evolution in its purely materialist form (random and purposeless) you only serve to maintain the supremacy of secular humanism and the marginalisation of Christianity.

    All this is wishful thinking on my behalf if the material observations of science support a material philosophy. But, recent publications such as Behe's 'Darwin's Black Box' and Schroeder's 'The Hidden face of God' demonstrate that material observations are far from supporting such a philosophy and can be used, legitimately, to support a theistic understanding of origins.

    Once philosophical materialism is demonstrated to have shaky foundations in science, or that material observations can support a rational theism, Realism will become the new governing paradigm, and realism includes a healthy critical assessment and application of revealed religion, because God is far from dead, God is not the product of human rationalism…God is very real indeed.

    Tough. It isn't 'only one of a number' - it is by far the best supported theory by the evidence. I can give you a nice list of this evidence if you like. Or are you persisting in using 'Darwinism' to mean 'things that might be peripherally related to common descent but which I disagree with'?

    quote:
    but I believe that if you promote evolution in its purely materialist form (random and purposeless)

    Again, tough. As far as science is concerned, the forces and natural processes which drive evolution are indeed purposeless, and are contingent on random events. Stop reading this as a philosophical statement with implications beyond the scientific sphere; it is not, and does not.

    Your last post reads as a sort of 'lets reject this, not because it isn't true, but because I think this position supports my philosophical position better'. Sorry, reality doesn't play that way.

    Neil, perhaps in the end we'll have to agree to disagree about whether the influence of philosophical materialism on Christian doctrine is "pollution" or "enrichment". I'm just going to respond to some of your specific comments if you don't mind (and again it could get a bit lengthy).

    First, about my comments about Greek (eg: neo-Platonism) and Babylonian (eg: Zoroastrianism) philosophies influencing Judeo-Christian thinking. You've conceded that the Babylonians introduced new concepts to the Jews during the Exile (the concept of Satan as the Adversary of God in Chronicles and Job is a good example of dualistic thought). I'm not quite sure how you can say neo-Platonism developed in the first century as a reaction to Christian doctrine; at this stage it appears Christian doctrine was still forming, and besides was hardly in the position to be a dominant philosophy to worry neo-Platonists. Instead, I would say, the Christian message was packaged into Greek philosophical (including Aristotlean as well as neo-Platonic) terms inorder to communicate to people versed in Greek philosophy. In the process a lot of Greek philosophical ideas were introduced to the Christian faith, the Creeds are much more in tune with Greek ways of thinking than Jewish ones. We can debate the extent to which this was good for the Church, clearly some of it wasn't (for example Gnostic ideas) and were rejected early on. However, I think such a debate deserves a thread of its own.

    quote:
    Recent external influences, which you see as a positive enrichment, are nothing more, IMHO, than post-scriptural influences on Christian doctrine and are pollutionist, not adding anything to the divine plan of
    redemption in Christ revealed in scripture


    Do I take it that you think that all advances in Christian thought since the writing of Revelation are at least suspect, if not wrong? Do you honestly think that a theology/philosophy expressed in terms that addressed the cultures of the Mediteranean 2000y or more ago will be relevant today? And if not where do you draw the line as to which relevant ways of thinking and expressing the Christian faith do you include or exclude? Hmm, maybe that's also a topic for another thread.

    quote:
    You are entitled to a theistic materialism, but I believe that if you promote evolution in its purely materialist
    form (random and purposeless) you only serve to maintain the supremacy of secular humanism and the marginalisation of Christianity.


    Evolution is a scientific theory, therefore by definition is purely materialistic. It is only when evolution is discussed as though it were a philosophical position that it supports secular humanism at the expense of theism. But, no matter how much the likes of Dawkins may want it to be, evolution is not a philosophical position.

    My philosophical position is materialistic, but not exclusively so. It is one of theistic materialism (I'm wondering if that's a term I've invented, but it fits what I believe); where theism and materialism offer different ways of seeing and thinking about the same reality (which was the point of my Holmes story if you missed that). In some contexts (such as when I'm at work) the materialistic becomes more important, at others (for example in church on Sunday morning) the theistic comes to the fore. But they are never entirely seperate.

    quote:
    ...if the material observations of science support a material philosophy. But, recent publications ... demonstrate that material observations are far from supporting such a philosophy and can be used, legitimately, to support a theistic understanding of origins.

    OK, can I make this clear. Material observations can be legitimately used to support both materialist and theistic philosophies, they cannot be used to disprove either position. In matters of philosophy, material observations are largely irrelevant.

    Neil - When do you date the life of Moses? Most place the events described in Exodus somewhere during the Mediterranean Dark Age (c. 1600 B.C. to c. 800 B.C.), while Zoroastrianism was founded sometime in the sixth century B.C. If you have some alternative historical timeline you'd like to propose, it might make a good topic for another thread.

    As far as the proposed connection between scientific thought and theism, I presume Alan is referring to monotheism, rather than general theism. Polytheism and Pantheism are still theism, even if they involve "capricious gods". But I find the explanation that "montheism expects order" is somewhat unconvincing.

    The origins of scientific thought lie not in Christianity or Islam but in late Archaic/Classical Hellas. (That's Greece, to you Latinates out there.) Despite being burdened by "a pantheon of capricious gods", people like Thales, Anaximander, Pythagoras, and Archimedes originated the materialism that makes science possible. In fact, I would argue that the Hellenes' capricious deities was one of a number of factors that allowed them to originate a mode of thought that would allow them to investigate the world without reliance on miraculous explanations, a mode of thought absolutely critical to science. The lack of satisfying religious explations for the world led them to investigate along other lines.

    Christian and Islamic societies did not develop science because of their monotheism. The monotheistic Zoroastrians were contemporaries of the Classical Hellenes, yet did not develop science. No, Christian and Islamic societies developed scientifically (at least in parts of their history) because they were the inheritors of Hellas.

    It is good to have you back on this thread. Did you read on in my post beyond the two quotes you used? I said, immediately after those quotes:

    quote:
    All this is wishful thinking on my behalf if the material observations of science support a material philosophy.

    It is amazing that you can not see that there is a difference between assuming naturalism for the purpose of science (which I have perhaps inconsistently supported as scientific on this thread) and adopting naturalism as a philosophy based on the results of science. It's a chicken and egg scenario. Naturalists operate within a closed loop. Their argument for a philosophy of naturalism goes something like "I am a naturalist because I use naturalism to investigate the material world which justifies my naturalism."

    As I said, if you read Behe, Schroeder and Birkett, three well qualified scientists, they each say that 'material observations or the products of naturalistic scientific investigation do not support a material or naturalistic philosophy' it is not a closed loop. The first two go a bit further to say that 'material observations of science support a theistic philosophy'. I say that they have gone too far, because I believe from a Biblical Theology that 'material observations of science are mute on aspects of philosophy' (which is why I asked Crœsos to define the basis of his atheism, because 'science' (material investigation) is not a legitimate basis for disbelief in a creator - it's a closed loop).

    Philosophical materialism is currently the loudest voice amongst the cacophony of voices that surround the material observations of science. Darwinism is only the 'best theory we've got', because the naturalist voice is the loudest and most widely supported (even by theists like yourself). Dawkins rants the way he does because his philosophical beliefs rest on Darwinism being true. But there is a growing voice amongst the cacophony which says 'we see design, wisdom and intelligence in creation'.

    Try turning the conclusions you drew on your own philosophical beliefs (which I have read and understand from your webpage). You can try and shout ID down, or rant about why it is wrong, but as you say 'reality doesn't play that way'.

    You seem to be saying 'let's reject this (ID), not because it isn't true, but because I think this position (random, purposeless evolution) supports my philosophical position better'.

    The gist of your post is summarised when you said that

    In the context of your post the 'other lines' are scientific investigations. Is science the basis for your atheism?

    I am delighted to say that I do not disagree with anything you said.

    The matter of application of scripture to life today is a matter for another thread, though I might clarify that I believe human nature to be the same today as it was 2000 years ago (effectively egocentric or 'Ptolemaic' with all the related relational problems that come with our selfishness). Christian doctrine takes our egocentric nature and turns it inside out and scripture is sufficient to reveal this to us and to offer the remedy for the situation. I do not deny that wisdom is found in many philosophies and religions and that we can learn from others, but I believe that nothing adds to the understanding of our relationship with the creator and outside the Bible.

    When I said I didn't disagree with you, your summary neatly ties up what I have tried to say rather awkwardly that

    quote:
    Evolution is a scientific theory, therefore by definition is purely materialistic. It is only when evolution is discussed as though it were a philosophical position that it supports secular humanism at the expense of theism.

    …OK, can I make this clear. Material observations can be legitimately used to support both materialist and theistic philosophies, they cannot be used to disprove either position. In matters of philosophy, material observations are largely irrelevant.


    My observation has been that when we (theists) try telling materialists, like Dawkins, that they can not use material observations to support their philosophy, we are told that we are being 'unscientific'. The term 'science' has come to engender both 'material observation' and 'philosophical materialism' in the minds of the public.

    Richard Dawkins opening paragraph in his preface to his latest book Unweaving the Rainbow writes:

    quote:
    A foreign publisher of my first book confessed that he could not sleep for three nights after reading it, so troubled was he by what he saw as its cold, bleak message. Others have asked me how I can bear to get up in the mornings. A teacher wrote to me reproachfully that a pupil had come to him in tears after reading the same book, because it had persuaded her that life was empty and purposeless. He advised her not to show the book to any of her friends, for fear of contaminating them with the same nihilistic pessimism. Similar accusations of barren desolation, of promoting an arid and joyless message, are frequently flung at science in general, and it is easy for scientists to play up to them.

    ...To accuse science of robbing life of the warmth that makes it worth living is so preposterously mistaken, so diametrically opposite to my own feelings and those of most working scientists, I am almost drive to the despair of which I am wrongly suspected. But in this book I shall try a more positive response, appealing to the sense of wonder in science because it is so sad to think what these complainers and naysayers are missing...The feeling of awed wonder that science can give is one of the highest experiences of which the human psyche is capable.


    I emphasised the word 'science' for good reason.

    Karl, my gripe is not primarily with evolution as a theory nor with theistic evolution as a philosophy, it is with the confusion, as Alan established, between naturalism as a method of investigation and naturalism as a philosophy.

    Dawkins has confused 'material observations' and 'philosophical materialism', he's caught within the closed loop that scientific investigation assumes naturalism therefore naturalism is true. He uses the term 'science' interchangeably between his 'feeling of awed wonder' from his work of observing material objects and his personal philosophy of 'nihilistic pessimism'.

    But, 'material observations' are mute on philosophy. Nihilistic pessimism is not science, it is a philosophy derived from material observations.

    Oh in the name of all that is holy! All that is amazing is that after reading all I've written on this thread, anyone should think that I don't understand the difference! I understand it perfectly well - how else could I agree with the statement that evolution is 'random and non-directed' - because I understand that that is a scientific, not a philosophical statement.

    quote:
    Darwinism is only the 'best theory we've got', because the naturalist voice is the loudest and most widely supported (even by theists like yourself).

    No. It is well supported by the evidence. Do you really want an in depth defence of Darwin's theory of evolution. It's ready if you want it.

    quote:
    But there is a growing voice amongst the cacophony which says 'we see design, wisdom and intelligence in creation'.

    Which of course is a philosophical position, not inherently opposed to Darwinian evolution. So it's not two systems in conflict as you seem to think.

    quote:
    You seem to be saying 'let's reject this (ID), not because it isn't true, but because I think this position (random, purposeless evolution) supports my philosophical position better'.

    The you misunderstand me. I do not reject ID as philosophy, merely as a scientific concept, which it is not. I accept random, purposeless (from a scientific frame of reference) evolution because that is what is supported by the evidence.

    Yes, sorry should have been clearer - Judeo/Christian/Islamic monotheism.

    quote:

    Yes, the origins of scientific thought. But that thought wasn't developed into science as we recognise it until much later under Christendom, and only then after a fair bit of Greek philosophical baggage had been jetissoned. Greek philosophers (and by and large that's what scientists and mathematicians were) were not that much into the popular religion of the time, as I understand it they may have followed the rituals of Greco-Roman religion but developed their ideas largely independently of the religion of the day and so were possibly not burdened by "a pantheon of capricious gods". However, they tended to be more concerned with philosophy than empiricism, which is reflected in their general fondness for mathematics and geometry (with an associated philosophical idea about perfect shapes) that was reflected in Greek architecture, Ptolemaic cosmologies of perfect spheres and the like; this tended to produce a "science" that tried to fit observations into philosophical expectations.

    quote:
    Christian and Islamic societies did not develop science because of their monotheism ... Christian and Islamic societies developed scientifically (at least in parts of their history) because they were the inheritors of Hellas.

    The Christian west rediscovered Greek thought after the so-called Dark Ages because that knowledge had been retained in the Islamic world, but it wasn't developed (at least to a great extent) by Islamic scholars, although I don't fully understand why but suspect it might be related to an attitude to the Q'ran as being the infallible word of Allah, so it was more important to study that rather than science - but I'm only guessing.

    Western Christians (I don't know about the eastern church at that time and how they may have viewed science) had a different philosophy than the Greeks, generally more interested in science as an investigation of the works of the Creator than an exercise in philosophical thought. As such were much more empirically minded, so for example when Copernicus realised that a helio-centric model for the motion of the planets worked better than the Ptolomaic geo-centric perfect spheres model the more philosophically pleasing model was dumped in favour of one that fitted the data better.

    Neil - Here's a story you might find informative. Once upon a time in my country there was a Vice President named J. Danforth Quayle, sometimes called "Dan" by his followers. This J. Danforth was not a very bright man and was an attrocious speller, but that didn't matter much because his chief duties were attending state funerals and formal dinners. One day, the Press Office thought it would be a good idea for him to be photographed with the winner of his country's National Spelling Bee. At one point J. Danforth, ever helpful and cheerful, decided that he would "assist" the National Champion in spelling a three syllable word. Of course, as I mentioned earlier, J. Danforth was an attrocious speller and only succeeded in embarassing himself by forcing a panic-stricken ten year old to put an 'e' on the end of the word 'potato'. Of course since this was a photo opportunity, the Press was there to fully document J. Danforth's foolishness.

    Now the point I'm trying to make here is that J. Danforth was not foolish or stupid because he was a bad speller. There are lots of otherwise intelligent people who can't manage to string three written words together without at least two spelling mistakes. No, J. Danforth was foolish and stupid for not figuring out that he had no business anywhere near a spelling bee or, failing that, he certainly should have known better than to arrogantly assume his spelling skills were greater than a National Champion.

    To apply this to your quoted comment, if you are aware of your own weakness in the subject of history you should not rely on historical references to prove or illustrate your points without some serious fact-checking and research, and it is doubly presumptuous of you to correct or question someone else's historical references, as you did at 14 August 2001 09:44, without the aforementioned research. And most certainly you should not just make up facts simply because they fit whatever philosophical point you are trying to make. (This last is only speculation on my part, but it's the best explanation I can think of for the origin of the "information" you posted.)

Because of this, I decided it would be best to "spin off" the topic into its own thread, Athens, Jerusalem, and Science.

    Karl, what are your thoughts on the following statement made ny William Dembski on the matter of Theistic Evolution?

    quote:
    Theistic evolution takes the Darwinian picture of the biological world and baptizes it, identifying this picture with the way God created life. When boiled down to its scientific content, however, theistic evolution is no different from atheistic evolution, treating only undirected natural processes in the origin and development of life.

    Theistic evolution places theism and evolution in an odd tension. If God purposely created life through Darwinian means, then God’s purpose was ostensibly to conceal his purpose in creation. Within theistic evolution, God is a master of stealth who constantly eluded our best efforts to detect him empirically. Yes, the theistic evolutionist believes that the universe is designed. Yet insofar as there is design in the universe, it is design we recognize strictly through the eyes of faith. Accordingly the physical world in itself provides no evidence that life is designed.

    Neil, I can't speak for Karl but that quote from Dembski is a very decent summary of my view except I use 'theistic materialism' rather than 'theistic evolution' because I don't want the implication that my philosophical position is limited to biological evolution. As such if I was making that quote I'd talk about theism & materialism in tension etc.

    Posted by Karl (# 76) on :
     
    Dembski's first paragraph is bang on.

    The second is not. God does not have to hide anything because the natural processes concerned with the evolution of life are the outworking of His creative activity. Like Holmes' stars, it is merely a matter of one's frame of reference.
     


    Posted by Dyfrig (# 15) on :
     
    It is "design we recognise strictly through the eyes of faith."

    So Dembski's position is philosophical rather than scientific?
     


    Posted by Alan Cresswell (# 31) on :
     
    Actually reading that 2nd paragraph of Dembskis' after Karls' comment there is something at odds with my ideas; God doesn't purposefully conceal himself like a master of stealth, it just happens that the way he chose to work in creation means he's visible in creation by faith only.

    And Dyfrig, yes it is a philosophical position. However, if you read some of his writings on (for example) the Origins website he doesn't appear to realise that.

    Can I add to Dyfrig's question...?

    How does William Dembski's philosophical position (ID) differ in its nature from say the philosophical nature of materialism ("Darwinian-influenced philosophy") or theistic evolution ("Darwinian & Christian -influenced philosophy")? I'm not asking how each philosphical position differs, but by nature, can any be said to have greater legitimacy than the other? If so, on what basis?

    Posted by Dyfrig (# 15) on :
     
    Neil - please don't try and make it look as if I'm siding with you on this issue, if you don't mind. Actually, I think Karl and Alan are more right than you on this point: you've attempted to "kill off" Darwinism and encourage the adoption of another attitude by claiming it to be more "scientific" when in fact it isn't - ID is as fundamentally flawed, if not more so, than anything Dawkins has to say. In fact, I'd go further and say that at least Dawkins basis his conclusions within the observable phenomenological world rather than try and introduce outside explanations which require "faith" - a perfectly scientific approach, said he, the lawyer.
     
    Posted by Karl (# 76) on :
     
    Neil - the evolution, or for Alan materialism, part is the science. The theistic bit is philosophy, it is not part of the science. Which is why Dembski is right that scientifically theistic and vanilla evolution are exactly the same.

    Actually I do prefer Alan's term but the 'Theistic Evolution' label has been around for a while, despite its shortcomings. Probably because it's with origins that people have the biggest problems.

    If I were to try to force the scientific evidence to support the theism, then I would be making the same mistake as Behe on the one hand and Dawkins on the other. I do not attempt to do that.
     


    Posted by Alan Cresswell (# 31) on :
     
    and about the only difference between me and karl is that I don't mind dumping a label, no matter how long it's been around, if it doesn't actually fit what I believe. I don't know whether "theistic materialism" is a label I invented or whether others have used it, and so long as it doesn't have an established use significantly different from my use of the term I don't much care.

    The only differnce between you and me is not the ability to change labels but the ability to change our views of the material world...I was once a chief deacon of the cult of Dawkinism (1986-1993), then perhaps a theistic materialist (1993-2001), now, perhaps an IDist (though the jury is still out...)

    No one has answered my question on legitimacy of philosophical materialism, theistic materialism or IDism. Are any legitimate philosophies, and if so, on what basis?

    Posted by Alan Cresswell (# 31) on :
     
    Philosophical materialism is a valid philosophical position provided it isn't built on methodological materialism (science) since there is no logical connection between the two.

    If by ID you mean a philosophy in which there are empirically measurable consequences uniquely identifiable as proof of design (which is certainly how Dembski, and from what's been said on this thread Behe, come across as saying) then the position is logically unsupported in my opinion.

    If you're saying ID is a philosophy with no such empirical consequences then to be honest the difference between ID and theistic materialism are almost non-existant.

    As usual, I disagree with Karl. I believe ID will help undermine the prominence of philosophical materialism and the practical atheism of the west. Turning to Richard Lewontin’s ‘The Doctrine of DNA: Biology as an ideology’, I’ve read past the introduction and have found a quite brilliant attack on the ‘nature not nurture’ ideology of biology (that we are what we are because of our genes). In his essay ‘All in the Genes?’ Lewontin says:

    quote:
    How are we able to resolve the contradiction of immense inequalities in a society that claims to be founded on equality? There are two possibilities. We might say that it was all a fake, a set of slogans meant to replace a regime of aristocrats with a regime of wealth and privilege of a different sort, that inequality in our society is structural and an integral aspect of the whole of our political and social life. To say that, however, would be deeply subversive because it would call for yet another revolution if we wanted to make good on our hopes for liberty and equality for all. It is not a popular idea among teachers, newspaper editors, college professors, successful politicians, indeed anyone who has the power to help form public conscience.

    The vulgar error that confuses heritability and fixity has been, over the years, the most powerful single weapon that biological ideologues have had in legitimating a society of inequality.


    This is a similar to University of California, Berkley left wing academic, Todd Glitin’s lament in his essay ‘In the twilight of common dreams’. Philip Johnson reviews Glitin’s work and summarises:

    quote:
    What the Left plainly needs is a new theolgy, with our without God. Glitin makes clear what the elements of such a theology must be. It must provide a universal vision that inspires people to regard themselves as fundamentally united, despite their differing social circumstances and cultural experiences. It must provide a basis for an objective rationality of both fact and value, refuting the current Left doctrine that “objectivity is only another word for white make subjectivity.” It must reject the market-orientated notion that individual gratification is the purpose of life, by providing a higher purpose. It must provide a reason for the economic winners to be generous and compassionate and for the losers to strive to become as productive as they are able.

    Where is such a theology to be found? I could offer a suggestion, but I don’t think Todd Glitin wants to hear it.


    If ID undermines philosophical materialism, then that theology, which Glitin would not care to listen to and the revolution Lewontin fears, might begin to make an impact in western culture. Kind of like a continuous Jubilee 2000. Not an armed revolution of the proletariat against the bourgeoisie, but a revolution of the heart of mankind.

    Neil - You seem to be applying some sort of philosophical litmus test to the legitimacy of scientific conclusions, arguing that they can't be valid because they don't agree with your notions of how God is supposed to operate. Your most recently quoted comments about genetics are of this nature, having nothing to do with the question of whether genetics or environment have a greater influence on human behavior. Instead, they propose what their authors would prefer to be true without any reference or scientific evidence as to what is more likely to be true. Regardless of which side of that particular debate one comes down on, this type of comment is idle speculation at best with no merit whatsoever. Castles in the air and angels on pinheads.

    You also seem to be attempting to apply a similar test to me, by asking me to explain my beliefs on a subject at best tangentially related to this topic. At the same time you have scrupulously avoided answering any substantive questions about the basis for your own positive assertions within the framework of this discussion. (For example, my as yet unanswered question about the Lorentz transformations at 14 August 2001 03:21.) The only reasons I can see for this "fishing expedition" is that either you are trying to decide if I am "philosophically worthy" of a response from you, or that you are trying to shift the focus of discussion from your unsupportable assertions (which form the origin of this thread) to a debate about whether my personal beliefs are valid. In the words of Joseph Welch in similar circumstances, "Have you no sense of decency, sir, at long last? Have you no sense of decency?"

    So getting down to specifics, which material phenomena do you believe are outside the realm of scientific inquiry?

    You are missing my point. I am not saying that material phenomena should be excluded from scientific inquiry.

    Let's take the mammilian blood coagulation cascade again. Scientific inquiry has now observed the material phenomena of how blood clots when mammals are wounded and how it avoids clotting otherwise. Scientific inquiry is now complete in this regard. With the understanding of how blood clotting works, science may now go on to investigate blood disorders like hemophilia.

    That description is the practical limit of scientific enquiry. Would you agree?

    Now, looking at the mammilian blood coagulation cascade, we can draw two philosophical conclusions. Either that it was the product of an unguided, unsupervised, impersonal, random, purposeless process or it was specified, designed to work that way.

    'Scientific inquiry' which goes beyond the 'how it works' and 'how can we fix it when it's broke' is in the realms of justification of philosophical materialism. Trying to prove that anything is the product of an unguided, unsupervised, impersonal, random, purposeless process can be described as 'science to prove a philosophy'.

    I've read this page on The Lorentz Transformations , the maths is a bit beyond me. I understand that The Lorentz Transformations are a speculative mathematical model which can not be empirically tested because we can not be in two places at one time. If we could test them empirically, are you saying we could deduce some philosophy from them?

    Why do you claim that your philosophy is not derived from scientific conclusions and then ask me to justify my understanding of scientific conclusions?

    My faith in God is based on the life, teachings, fulfillment of Old Testament Law and prophesy, death, resurrection, ascension and future return of Christ Jesus.

    What's yours based on? Put it negatively, who do you think Jesus is?

    You said on the same post

    quote:
    As far as my non-belief in God goes, it is simply a result of my never having needed to hypothesize a Deity.

    In light of my question to you about Jesus, there is no need for you to hypothesize. Faith in Christ is not subjective, Jesus was/is very real.

    As far as your need goes, are you any different from the rest of us? Like it or not, if Christianity is true, if what Jesus taught is true, we will all face moral accountability and our need for an advocate on that day will be very great indeed. Have you considered this carefully?

    Well, I wouldn't agree. Leaving aside that I doubt all the chemical signallings related to the process are known, I would say the origin of the process is still a valid, and potentially vital, part of scientific enquiry. What did the proteins currently involved in blood coagulation do before the DNA that make them mutated? What was the nature of that DNA mutation? How did proteins originally suited to other tasks get together to do a different task? Answers to these questions might even explain why the process sometimes goes wrong. And it's all good science.

    The Lorentz Transformations are mathematical constructs, but hardly speculative. Granted they were originally developed as mathematical curios, but Einstein applied them as the mathematical basis for his theory of general relativity with all the empirically verified predictions of mass-energy equivalence, time dilation etc.

    Your motivation for seeking the previous function, if there was one, for the proteins involved in blood clotting is a valid scientific inquiry. But, as I said to Crœsos, why do we keep referring the detail of scientific theory when we are talking about governing philosophy? Can you explain to me in lay terms, keeping in mind that I am a civil engineer, whether or not philosophical materialism or atheism can be proved by The Lorentz Transformations or any other mathematical, empirical or biological function?

    In further response to Asto's question, I would like to highlight the difference between theistic materialists (theistic evolutionists) and proponents of intelligent design. To do this, we need to asked why, if Christianity can provide a revolution of the heart of mankind akin to Todd Glitin's outline, has that revolution not taken place? Why has the reverse occurred in Western society, where inequality between socio-economic groups, races and countries has increased towards the latter part of last century?

    If we take a hard look at secular humanism, the governing Western philosophy, we find that Christianity is permitted a subjective position in society. I commend to everyone on this thread the study of the Council for Secular Humanism - A Secular Humanist Declaration . Reading all items in the declaration we find that 'Religious experience' is permitted as subjective if helpful to the individual.

    What are the effects of this on Christian practice? Charismatics can raise their hands and speak in tongues, if that's what they want to do, subjectively. Anglo-Catholics can wear cassocks and surplices and stand north facing at the 'altar', if that's what they want to do, subjectively. Evangelicals can earnestly study the bible and apply it to their lives individually & corporately, if that's what they want to do, subjectively. We can even fight amongst ourselves about which is the right manifestation of corporate gatherings in our faith in Christ and run the 'Mystery Worshipper' to highlight the differences. But, if we claim that Christianity is more than a subjective experience, if we claim that Christianity is true, we're told that we're either mad to believe such nonsense or that we are stepping out of place.

    If we are Christians then we identify with the sacrifice offered by Christ, once for all. It is true, not only for Charismatics, Anglo-Catholics and Evangelicals (regardless of our preferred style of corporate gathering on Sunday) it is true for all humans. But philosophical materialism, secular humanism, keeps the practical atheist 'safe' from that truth because we are told 'what works for you is fine, but please don't pester me with your subjective experience'.

    Now, to the point of this thread. What is the mechanism which has relegated Christianity from its true theological position as objective truth to a false theological position as subjective experience? It is the mechanism of Christianity being subset of philosophical materialism. Of crucial importance to this situation is this question, what is one of the greatest supporting 'objective facts' of secular humanism? It is the unguided, unsupervised, impersonal, random, purposeless development of life on earth. According to secular humanism, humans are what we are, not because we were made this way but a supernatural being, but by a material process over which there was no control. At the deepest level, Darwinian theory excuses us of any moral responsibility. Christians have no choice but to retreat to a subjective belief and practice, because we have been marginalised by secular humanism and the 'triumph' of Darwinism as a means of explaining our origin and development.

    But, ID challenges the objectivity of the claims of the Darwinian theory of evolution, not because it wants to undermine secular humanism, but because ID does not accept Dawkin's 'Blind Watchmaker' thesis because it does not fit with the evidence of complexity in life. ID says that there is a watchmaker. Michael Behe's observations may or my not be empirically detected, it may not be possible to detect that blood coagulation cascades are the product of intelligence, but Michael's Behe's deductions are at least as legitimate as Richard Dawkin's. Like my earlier example of the oxygen-carbon dioxide cycle, one will see it as fluke and another critical design to life on earth.

    ID undermines the authority of secular humanism, because, without conclusive supporting 'scientific' objectivity, secular humanism suffers the same fate as Christianity suffered post-Enlightenment. Without Darwinism, secular humanism is reduced to subjective faith, not objective reality. Practical atheists might find that there is no philosophical or 'scientific' basis for their faith after all. And our Christian faith, our faith in Christ, may be elevated again to a position of objectivity not subjective experience.

    Let the revolution begin.

    The question of how something came to be is valid science as in methodological materialism. Answers to such questions provide no more support for any philosophical position than answers to "how it works" questions.

    Neil,

    Christianity is about relationship with God through Jesus Christ. This will differ for everyone who has experience of it.

    The particular view of Christianity that you propound appears to be directly arising from Enlightenment presuppositions (particularly in relation to its treatment of "objective truth").

    To succeed, a revolution must choose the critical moment. Modernism is well past its sell-by date, and is highly questionable as the basis of any new paradigm.

    Neil - If you'd take the time to refer back to my original (and as yet unanswered) question about the Lorentz transformations on page 12 at 14 August 2001 03:21, you'll see it was in response to one of the items on a list you purported to have written in which you described the concept of imaginary time as "highly speculative". Since the "gamma factor" in the Lorentz equations strongly implies the possibility of imaginary time, I mentioned it as a refutation of your point, not as any sort of absolute proof of God's non-existence. As for why we "keep referring the detail of scientific theory when we are talking about governing philosophy", I suspect it is because you keep making scientific assertions in support of your own theorizations in this matter, and the "facts" you cite (such as the bit about imaginary time) are often dubious, if not outright incorrect. If you don't want to get bogged down in materialism or science, quit making material and/or scientific assertions! And by all means don't get so huffy when someone decides to call you on it!

    As Alan pointed out, the Lorentz transformations are not speculative and can be demonstrated using any number of means, the most famous of which is the solar muon experiment. Alan did have one thing incorrect though. Einstein used the Lorentz transformations in the formulation of Special, not General, Relativity.

    Its not the scientific fact that you have the problem with then. I'm afraid you can't really say that someone using a scientific theory to justify their philosophical beliefs makes the theory they are referring to any more or any less "correct" ( whatever that means hey guys

    I'd suggest that attacking a shaky philosophy is a lot easier than attacking what is, like it or not, an exceedingly well-supported scientific theory.

    Looking back at this thread, I have been surprised by the level of passion and determination displayed by some of the Christians on the board in defense of Darwin's theory of evolution (the unguided, random, purposeless development of all life on earth). If only Christians would defend Jesus with such vigor.

    Why is this? Why is Darwin's theory defended more passionately than Christ Jesus?

    Ham 'n' eggs, you mentioned presuppositions which reminded me of the arguments over 'the new hermeneutic'. You have made a very valid point, that we see what we do because of our presuppositions. Can it be that our presuppositions influence our interpretation of material phenomena in the same way they influence our interpretation of the Bible?

    It is not that the same set of presuppositions is applied to material phenomena and interpretation of scripture, but that both disciplines are affected by our particular set of presuppositions.

    IMHO, the concept of 'the new hermeneutic' can be applied to our approach to Darwinian theory. The 'evidence' for the unguided, random, purposeless development of all life on earth is strong but incomplete. It therefore requires human thought to extrapolate ideas which complete the theory, human minds expand the evidence to fit the theory. Darwinism is a theory of grand extrapolation, variation in finch beaks and peppered moths are extrapolated to form a grand scheme of a developmental process for variation and complexity. The extrapolation is achieved by a process which involves our presuppositions.

    We are not born with any presuppositions, so where do our presuppositions come from? The classroom, TV, our surrounding culture, including, of course, the books we choose to read (and those we choose not to read), the evidence we choose to see and that which we choose to ignore.

    Darwinism, therefore, survives not because it is objectively true or unfalsifiable but because of our presuppositions, our cultural & historical environment. This is as true today as it has been for every other culture and time before us which has observed material phenomena. Observations of material phenomena, whether those observations are true or false, have been adopted to suit our presuppositions. The theory of a flat earth fitted a presupposition. The Ptolemaic theory of the universe fitted a presupposition. Darwinism fits a presupposition. Each theory has been defended passionately and dogmatically when new theories begin to emerge and Darwinism is no different. The dominant western philosophy requires (neo)Darwinism to be true, so (neo)Darwinism is true because of that presupposition, not because it is objectively true.

    Neil

    PS Crœsos…you haven't explained who you think Jesus is.

    PPS Doug have you read the Council for Secular Humanism - A Secular Humanist Declaration ? Particularly items 8 and 9.

    Kirsten Birkett in her book 'unnatural enemies: an introduction to science and Christianity' writes:
    quote:
    The physical world was created by God and everything in it continues to be sustained by his will. Thus, any true theory of how that physical world works cannot conflict with a Christian view of God, for the Bible says that the physical world is entirely moved and controlled by God, working in and through what we regard as 'natural processes'.

    Important implications flow from this. Firstly, finding a 'natural' cause for an event is no reason to dismiss God as the fundamental cause. In fact, if nothing else, our survey of the biblical teaching should make clear that the word 'natural' is rather inappropriate, especially if it is contrasted to 'supernatural'. In the end, there is no difference between the two, in the Bible's view. All causes within the world are ultimately caused by God. So even the most complete scientific theory, with every causal chain thoroughly described, is no reason to conclude that God is not there. From the Bible's viewpoint, it is merely an elaborate description of the wise order that God has created, and now sustains, in the world. The two are not competing explanations; they are both true explanations.


    If science and Christianity are 'unnatural enemies', why is there conflict? The conflict arises, not over the material evidence, but over a theistic presupposition and an atheistic or deistic presupposition. One view, as Birkett points out, is based on a biblical view of the world, what are the other ones based on?

    Perhaps because if he's the son of God he should be better placed to defend himself than a mere theory?

    Also because this thread is about "The Death of Darwinism" not "The Death of Christianity".

    And finally because a lot of Christians misidentify the Theory of Evolution as their enemy.

    Neil, on here the basic truths about Our Lord are a given; the debate is about certain scientific theories, and certain philosophies.

    Rest assured that on secular creation/evolution debates I defend the Faith with the same vigour as I defend mainstream science. Indeed, the only reason I arse around with these debates is to present the rational Christian view, lest the creationist lie of "creationism=Christianity, evolution=atheism" be strengthened.

    I would dispute this assertion. Darwinism survives, in the face of other, better, later, theories for the same reason that Newtonian Mechanics survives in the face of Einsteinian Relativity, because, at a simple level, it works and is understandable.

    In order to progress beyond the simple assertions of the Darwinian world view requires a grasp of the underlying subject that is beyond the majority of people in this country (and elsewhere). The more complex theological and even biological consequences of Darwinism are as obscure to the majority of people as are the Lorentz Transformations.

    Welcome back John, I wrote a commentary on the 'Discovery' program on this afternoon's BBC world service and your quote
    quote:
    And finally because a lot of Christians misidentify the Theory of Evolution as their enemy.
    tees it up nicely.

    Kirsten Birkett shows why science and Christianity are not at odds, because a Biblical understanding of the world expects order because God is an ordered God and 'natural processes' are part of God's order. But, Christianity did not make an enemy of science, science made an enemy of Christianity and continues to do so, and the BBC gave a classic example today. By assuming naturalism for science, scientists have come to believe that naturalism is true.

    The 'Discovery' program today was titled 'Pain is a problem'. The program was introduced by the statement

    quote:
    'Pain is a problem, it was once religion which tried to answer the problem of pain, but now science gives us the answer to the problem...science has shifted pain from morals to mechanisms.'

    After discussing the way pain is detected in the body, by interviewing many scientists who described how our bodies detect pain, the program turned to 'Christianity'. One interview was made with a Christian art critic who described works of Christ in pain on the cross and described an American gay HIV+ artist whose name I forget and whose stage show involved self mutilation, including many Christian overtones such as a crown of steel thorns. These religious overtones were attributed to the fact that this artist was the child of religious fundamentalist parents, and he had been 'groomed for Christian ministry', obviously making him the screwed-up basket case he is(was?) now.

    The art critic was scarcely relevant to the question, but at least she provided a good straw man of an artist whose self expression of pain as art was the result of unscientific religious fundamentalists. Why didn't the program try quoting CS Lewis from 'the problem of pain', where the program had perhaps unwittingly derived its title? Perhaps that would have given too serious a consideration to Christian thought.

    Having dealt such a blow to the credibility of Christianity, the program turned back to science and molecular mechanisms, neurons, inheritance and experiments on mice, good rational stuff. Then it took a poke at Dr Livingston's report of being attacked by a lion. When Dr L experienced no pain during the mauling he concluded that it was a 'merciful provision by our benevolent creator to reduce the pain of death'. Back to science, and 'opiod peptides', which explain Dr Livingston's lack of pain...'you see' implied the program 'there is no need for God to be involved at all.'

    The conclusion was that pain was a problem but science would solve it with drugs and pain killers. Well done science and well done BBC, good reporting, if you count good reporting as a biased, bigoted, intolerant, illiberal treatment of a serious issue.

    The real problem of the painful treatment of this subject was that the producer was only being faithful to his presuppositions...that science is rational and Christianity is barking mad. The frightening thing is that this is not some right wing fascist extremism, inciting religious intolerance and hatred, it is main stream global broadcasting in the name of 'science'.

    Steve_R, before making patronising comments about people being too simple to understand science, please go back and read my post of 17 July 2001 10:15. Richard Lewontin explains why that argument is not only patronising but the very reason 'scientists' are allowed to make programs like the one on the BBC World Service today without being criticised for being bigotted, illiberal and guilty of inciting religious intolerance. Do you really believe that philosophical naturalism can be defended by telling non-scientists that they don’t know what they're talking about? That's what the bishops of the mediaeval church tried to do when their beloved doctrine was under attack.

    The BBC article demonstrates that this is not about 'evolution' or any other beloved theory, it is about legitimacy amoungst the intellectual elite.

    I think the problem is not the ligitimacy of science, but the perceived illigitimacy of religion that is the problem - that's why the scientific answers are preferred to, rather than taken as complimentary with, religious ones.

    This is not helped by attacks on science, whether they come from Michael Behe or from Duane Gish.

    Neil,

    Perhaps congratulations on your stamina are in order, for keeping this thread going so long. Can I observe that you seem to be clinging to your initial position with some tenacity (in the face of some very knowledgeable and reasonable comments by Karl and others) ? Seems to me that both sides (those who talk up conflict between science and religion and those who play it down) feel fairly strongly about these issues.

    quote:
    posted by Neil Robbie:
    If science and Christianity are 'unnatural enemies', why is there conflict?

    Perhaps this conflict centres around the T-word. "What is truth?" asked Pilate, and then left the room, thereby missing out on at least 14 pages of intelligent argument...

    What is it stake is whether Christian religious beliefs are a "truth" that is "truer" than scientific "truth" (a position we might call "religious supremacy"). Or vice versa ("scientific supremacy"). Or whether these sorts of truth are complementary.

    Blaming "science" for the conflict is unfair. It goes back at least to the days of Galileo, and at that time in history the Church claimed an authority over scientific "truth" - the religious supremacists were in power. [the details of the Galileo affair aren't relevant; the point is the attitude to truth].

    I'm in the "complementary" camp - both science and religion are valid realms of human understanding, and properly understood there is no conflict between them. I don't feel that this position is undermined by any amount of quoting scientists who hold "scientific supremacy" views. Nor is the validity of "scientific" truths undermined by pointing out that scientists are only human and therefore form their views in the same way that other humans do.

    Why does it matter ? Because people are in need of God, and misrepresenting Christianity as anti-science creates a barrier on their path to finding Him...

    Urgh. I was trying to stay away from this thread, but I couldn't let this slide. Darwinian evolution does not rest on blind chance. It is rather better explained as chance mutation plus natural selection, natural selection being anything but random. Chance alone would be astronomically unlikely to result in the development of the human eye. Such mutations, followed by such selection, as has been extensively laid out by others here, are overwhelmingly supported in the fossil record.

    What I really can't believe is that certain people have so much invested in "disproving" evolution. I'm insulted that anyone would assert that passionate championing of good science represents a failure to champion Jesus, as if he needs it anyway. Jesus was all about Truth, and not (to the best of my reading of Scripture) all about using twisted and underinformed pseudoscience to cling to absurd views.

    I wrote the following before reading the posts which followed my rant about the BBC. I hope you enjoy this post...


    Karl

    I wish to offer you an apology for the way I have behaved on this thread and argued so strongly against your position of theistic evolution. I am truly sorry and hope you can forgive me.

    You might wonder what has brought about my change of heart. As you know, the matter of science and Christianity is fairly new to me. I have been a Christian for 9 years and have chosen to ignore science rather than face the challenge it makes, in its popular form, to Christianity. Reading Philip Johnson and Michael Behe hit a chord with my personal view of the world, which I described in the way I saw the intelligence of the oxygen-carbon dioxide cycle in animals and plants. Because their views fitted my own presuppositions, I assumed ID was true and picked up their claims as dogmatically as some claim other theories.

    As you know I have been juggling many books during the writing of this thread (including Behe, Schroeder, Johnson, Dawkins, Gould, God (the Bible), Whitcomb and latterly, Birkett). Well, I finished Kirsten Birkett’s book (Unnatural Enemies: An introduction to science and Christianity) last night and she changed my mind on ID and theistic evolution, though she mentions neither in her book and I am not saying that either is correct.

    Kirsten Birkett is a lecturer at an Anglican seminary in Sydney Australia (if you know which one, please do not write her off as conservative Evangelical, her treatment of the matter is balanced and enlightening) and she teaches on science and Christianity. If you would like to find out why I no longer believe ID to be science and worth defending, you might like to order her book which you can get from The Good Book Company for a fiver.

    I remain convinced of intelligent design, but not in the sense the ID movement states, because I do not think, as many people pointed out to me, that the empirical evidence can be shown to ‘prove’ irreducible complexity or specified complexity. These are two more theories waiting for science to show how they came into existence. I believe in the ongoing work of God in creation from an informed Biblical Theology.

    This is not to say that I have given up against the claims of science to replace religion. Thomas Huxley may have won the day and his influence on the minds of popular culture today is still immense. John, remember my list of parallel positions within science as the new church, and you asked me what planet I was on? Well, it was not me, but Thomas Huxley that established that way of thinking. He referred to the ‘church scientific’, himself as one of its ‘bishops’ and his talks as ‘lay sermons’.

    It is the ‘church scientific’ which is the enemy of God’s church. Christianity did not make science its enemy, science assumed the position of the aggressor 160 years ago and maintains that popular stance with proponents like Dawkins. I no longer think that ID will undermine the authority of secular humanism, philosophical materialism or naturalism, but as someone clever said at the start of this thread scientists are not to be found in church because of the current vacuity of the message. The church needs to get up out of the dust, brush itself off from the beating it has taken since Huxely’s days and put science in its proper place. Then perhaps, the BBC will stop broadcasting anti-religious claptrap and Glitin’s revolution may begin.

    Humble apologies again, Karl and everyone else who was on the wrong end of my blind dogmatism.

    Can we change the focus of the thread to the question of putting science in its proper place? How can we as a church achieve a proper public understanding of the relationship between science and Christianity? That is that science and Christianity are unnatural enemies and that it is the claims of the 'church scientific' which has assumed the role of aggressor and victor without reasonable grounds.

    With the benefit of GMT+7 hours and reading Kirsten Birkett's book (BTW, if you visit the Good Book Company, the 'Unnatural Enemies' can be found under the 'engaging with the world' section), the difference between theology and the 'church scientific' is our understanding of the terms you used to describe evolution

    quote:
    chance mutation plus natural selection
    .

    This is the crux. How do we understand chance mutation and natural selection? How does 'chance' fit with a Biblical understanding of God? Does 'natural' selection involve God or exclude God? (cf my post of 20 August 2001 05:35)

    No, Neil, I haven't explaine who I think Jesus is for two very good reasons, at least in my own estimation. First, my personal opinions of Christ have very little to do with the subject of biological evolution, materialism, or science in general and is thus totally outside the present topic. I'm fairly sure you're only so dogged on this subject because it is a last, desperate attempt to shift attention away from several scientifically untenable claims you presented as "scientific". If you're really interested, you could start a "Who was Jesus?" thread, which would be a much more appropriate venue for my answer. Secondly, you have not answered my question regarding your own apparent dislike of the theory of imaginary time, which was asked before you even brought up my personal opinion of Jesus.

    It is interesting you mention the question of pain and pain relief. It was a popular theological position in the mid-nineteenth century that the use of painkillers or anesthtics during childbirth was immoral and unChristian. The origin of this opinion was an overly-literal interpretation of Genesis 3:16, which stated that it was woman's Divine Punishment that "with pain you will give birth to children". By mitigating this divinely ordained suffering, scientists were perceived as "playing God". The controversy was quietly ended when Queen Victoria (the era's standard for all that was good and upright), who had already borne eight children in such Biblically proper pain, used an anesthetic when birthing her ninth child and pronounced the experience greatly preferable. This is, of course, just an interesting anecdote, but it illustrates something alltogether too common. One of the reasons that science and religion are often at odds is that science is largely about novel and unusual things, whereas relious belief (at least as it is practiced in Western culture) is drawn towards the old and preserving the status quo.

    Neil - Unless your concept of God is subject to material verification, He is excluded from natural selection as a scientific concept. As far as how chance fits with a Biblical understanding of God, I am unaware of any part of scripture that deals with probability or statistical analysis, but I am far from an expert on the subject. Perhaps you can give us a few hints as to the way in which the existence of a Deity can be factored into probabilistic equations.

    Science and religion are frequently at odds (or at least, naive scientists and naive religionists are frequently at odds) because we are heirs of the Cartesian dualism of the "objective" and the "subjective". Science, this dualism would have us believe, is the realm of fact, of data, of the provable. Religion is the realm of values, of meaning, of morality, of the ethereal and the ineffable.

    Now this dualism, this division of human knowing into two separate spheres- the objective and the subjective- held together for a while; at least, until the Enlightenment got under full steam and issued in the skepticism of the 18th and 19th centuries, when it seemed possible to dispense with anything other than the vague moral sense that religion might provide one with. Of course, eventually people realized that one didn't even need religion for a sense of morality.

    In the 20th century this Cartesian dualism has issued in a division of "fact" and "value"; science holding all the facts, religion- and other similarly etheral things like ethics- holding the values. Facts are incontrovertible, provable units of sensory experience. Values, on the other hand, are relative, arguable, and unprovable mutual agreements between people.

    In reality, of course, as much late 20th century philosophy of science and religion were to demonstrate, the Cartesian dualism of "objective" and "subjective", of "fact" and "value", was just so much imaginative fancy. The truth is that scientific and religious communities (not mutually exclusive entities) conduct themselves in very similar fashion: each is done in community, so providing a check on the idiosyncratic and heretical; each has its dogmas or postulates, unprovable assertions on which the epistemological system is based; each depends on models and metaphors, sometimes on successive paradigms (thank you, Thomas Kuhn), to provide a common language for members of the community ("believers", if you will).

    Even the notion of "objective" is suspect, because we now realize that there are no uninterpreted data, that merely deciding what counts as data ("facts") is a matter of interpretation, that every decision (including the dogmatic postulate) amounts also to a decision to exclude, a prior, what is decided not to be a datum.

    The problem arises when a naive scientism, represented both by many practicing scientists and by most layfolk as well (isn't is interesting how we use these "religious" terms to describe such things?), insists that it provides the only reliable guide to reality, that its conclusions are provable and that those of religion are not (well, of course they would be when what is provable is defined a priori in such a way as to exclude the activity of God).

    Absolute codswallop. We can no more prove that only that which is empirically verifiable exists (or even that empiricism can define the limits of creation) that we can prove that God exists. Empirical materialism makes an excellent methodology, but when pressed as metaphysics (as thoroughgoing empirical materialists do), it becomes as thoroughly dogmatic as any creed.

    (Understand that, as a creedal catholic Christian, I am not attacking creedalism. On the contrary, dogmatic assumptions or postulates or axioms are necessary in any system of human knowing, or you are paralyzed by the inability to decide what constitutes truth in any sense.)

    In the end, science and religion are very two very similar ways of appropriating one way of human knowing, but to different ends: on the one hand the way the physical, empirical determinable universe behaves; and on the other hand, discernment of ultimate meaning, of truth, of value (in the sense of worth), and for followers of biblical religion- Christians and Jews- the discernment of the creating, revealing and saving activity of the one true and living God in his creation.

    To return to the issue that has produced several hundred posts on this thread alone (leaving aside hundreds of posts on similar threads on these boards in times past), my position is this: no Christian, no believer in biblical religion (in the sense of Christians and Jews) can uncritically accept the assumptions and conclusions of Darwinian evolution. Don't misunderstand me on this point; I find "young creation science" intellectually shallow and in some measure self-delusional, and I sense in the Intelligent Design movement (while I respect their bravado in challenging a scientific establishment in its comfortable and unquestioning dogmaticism) something akin to an Anselmian rationalist attempt to prove God's existence. But no believer in biblical religion can accept the idea that only the material, the empirically verifiable exists; both Judaism and Christianity teaches that God is the Creator "of all that is, seen and unseen." The foundational axiom for empirical materialist science is that only that which is empirically verifiable may be said conclusively to exist. The foundational axiom for Christian faith is that the Word of God became incarnate, took human flesh, in Jesus Christ.

    Nor can that believer accept the idea that the creation of life has proceeded in an entirely directionless manner (this obtains regardless of one's views of chance and natural selection, see Laura's and Neil's posts, above- neoDarwinian evolution insists that there be nothing teleological about evolutionary development, however adaptive it may be) or that life developed in a manner necessitated by the historical exigencies of environment. The first notion is a denial of God's sovereignty and intention in creating humanity, so that rather than our being created for dialogue with God and for God's delight in us (and we in God), we can at best conceive of God's involvment in the rise of human life to be something on the order of realizing one bright and sunny epoch, "Hey! There's a creature down there now that I can talk to!" The second notion, of the necessity of human development, is a denial of the sovereignty and grace of God in creating us; rather than beings whom God created freely for dialogue and delight, we are being who necessarily arose form the historical exigencies of the primordial ooze.

    Having said this, that I find neoDarwinian evolution to be incompatible with the biblical revelation of God because of its foundational assumptions and its anti-teleological conclusions; and that I find "young earth creation science" to be intellectually untenable (and it denies the vastness of God, too, to insist that it had to be done over the past 7000 years- that's a mighty damned short eternity past!); and that I find the Intelligent Design movement suspect, not because of any dissembling or obfuscating on the part of the considerable intellects involved, but because I find it too rationalist for my biblical-fideist soul; where am I left?

    With something that many long-time posters here have read from my keyboard before: creative evolution or evolutionary creationism. What do I mean by that? Well, not theistic evolution, at least as that is usually defined (that God creates the universe- Big Bang- giving it a sort of push in the direction of eventuating in human life- strikes me as remarkably deist in belief). What I mean is that I believe, as fervently as any young earth creationist or intelligent design proponent, that God created all life- all life- in the universe (hence its being called "creation"), not by filling in gaps where "missing link" couldn't carry on the evolutionary process, but in every moment, every nanosecond of the creative process. Viewed from the perspective of an empirical materialist methodology, this looks very much like evolution (whether gradual or punctuated), because God creates (dare I even say, experiments?) to fit the environment.

    The time has come finally to liberate our common way of human knowing from the epistemological shackles of Cartesian dualism (or better, of its latter-day bastardy), to restore science and religion to their proper places in human endeavor.

    Man the barricades! To arms!

    Many thanks Todd

    As an example of the ongoing battle, I heard another BBC World Service program today called 'Racial myths' which was a puff for the legitimacy of science over morals to the exclusion of Christianity.

    The program followed this argument. It claimed that 'race sciences' were responsible for racial genocide in the 1830s and 1840s, for example when the British wiped out Tasmanian Aborigines. Moral justification for the genocide at that time was based on the scientific fact that primitive people were doomed to extinction. But, claimed the program, 'liberal racial attitudes' were responsible for the abolition of slavery at the same time (1838). Now, this is contrary to my understanding of history in which Wilberforce, The Clapham sect and John Newton were responsible for the abolition of slavery (but the BBC would not want to attribute anything beneficial in society to Christianity).

    The program went on to Scottish Historian and philosopher Thomas Carlylse who was described by the program as 'a prophet, a sage' (and the use of religious language for such a racist was, IMHO, no accident). Next, Scotsman Robert Knox, the notorious gravedigger, and advocate of racial genocide who claimed that

    quote:
    races are naturally and essentially different, race is a fact, it is everything.
    To accept that fact, said Knox, was to speed up the process of racial genocide. The program sourced Darwinism as the foundation of Knox's conclusions and then it turned to Darwin's own teaching in The decent of man. It claimed that Darwin's work stated the fact that
    quote:
    'at some period in the future the civilised races would exterminate the savage races'
    and that this was a disturbing but real conclusion Darwin faced.

    Then the program brought in the hero on a white charger, 'the Liberal establishment', John Stuart Mill (backed up by Huxley, Darwin & Lyle) whose critique on Thomas Carlylse (which was backed by Dickens and Charles Kingsley) abolished the scientific conclusions Carlysle had read into Darwin's theory. Hooray for the liberal establishment. Hitler was then discussed as the last hangover of the conclusions of Robert Knox and Thomas Carlysle.

    And the conclusion of the program?

    quote:
    'Now science is undoing the damage done by the pseudo-science of Darwinism, because genetics are showing that we are one race'.

    Rather than commending Christians with the abolition of slavery and admitting that the Bible was right about the essential unity of humanity, the BBC once again says a big 'well done' to science for defeating racism and abolishing slavery. Biased, bigoted, anti-Christian, inflammatory reporting by 'the liberal establishment'.

    Unbelievable. So, in light of such reporting, how do we

    Todd - your position sounds rather more like theistic evolution as I understand it than does your description of theistic evolution. Any form of 'God of the gaps' or distanced deism I avoid like the plague.

    I'm not so good on the technical descriptions - I didn't read philosophy - but the way I've always put it is that evolution, whilst purposeless and undirected from a scientific frame of reference, nevertheless is the outworking of the creative activity of God, which has both purpose and direction. Does this make any sense?

    I stand by my original comments as not being patronising but, unfortunately, true of the scientific knowledge of the majority of people.

    Darwinism captured the imagination of the Victorian society on whom The Origin of Species was initially launched and until some counter-theory does the same then the simplistic notions that are generally understood by Joe Public to be Darwin's theory will remain in the consciousness. This will also be aided by the fact that the essential elements of evolutionary theory (disregarding the genetic, theological and other complexities) will be taught early in school biology and even where they have been adjusted for later theories they will still be credited under Darwin's name.

    I am sorry for my outburst and for accusing you of patronising non-scientists, please forgive me, I will try not do it again. If you take time to read that post again you will see that my statement was a summary of Lewontin's quote. I said, in summary,

    quote:
    I found the above statement refreshingly honest. Lewontin has stated the truth clearly and concisely…God is dead…science rules ethics, morality, culture, purpose and meaning.

    Joe Public has no way of questioning Lewontin's philosophy because, as Lewontin pointed out, no one understands his science.

    My questions are these?
     What gives science this legitimacy?
     What keeps Darwin's philosophical train in motion?
     How will the church counter this legitimacy?


    I was summarising that Lewontin tells people like me, Joe Public (an engineer outside the main body of science), that I don’t know what I'm talking about and so I should remain silent. This is not about whether or not Darwin was right in his observations but whether Lewontin as a philosophical naturalist has greater legitimacy than a philosophical theist to shape public morals and ethics. Todd has explained that this assumed legitimacy stems from corrupted Cartesian dualism, that is that

    quote:
    Science, this dualism would have us believe, is the realm of fact, of data, of the provable. Religion is the realm of values, of meaning, of morality, of the ethereal and the ineffable

    BBC programs which give science moral legitimacy and no legitimacy to Christianity are a product of this corrupted understanding. Therefore, as Todd has answered the first two questions, the last of my three questions from over a month ago remains valid and unanswered. Todd has said that

    How does your 'theistic evolution' vary from Kirsten Birkett's summary

    quote:
    The physical world was created by God and everything in it continues to be sustained by his will. Thus, any true theory of how that physical world works cannot conflict with a Christian view of God, for the Bible says that the physical world is entirely moved and controlled by God, working in and through what we regard as 'natural processes'.

    I should add that, in context, Birkett means that if the observed path of the development of life is gradual or rapid, by mutation or otherwise, selection or otherwise, whatever the conclusion of scientific observation it is not in conflict with a Biblical understanding of the way God works in creation, because God is at work through 'natural processes', though we can not always predict how God will work, because God is God and we are not.

    Todd,

    I agree with lots of this, but not (as currently phrased) to your dislike of objectivity.

    quote:
    Originally posted by Todd:

    Is the problem when people equate "objective" with "empirically verifiable" ? That there is a distinction between that which is empirically verifiable and that which is not seems obvious. But things which are "subjective" are normally mental phenomena. Christians want to say that although God is unprovable (not empirically verifiable) he is objective (having an existence independent of all human thought) ?

    quote:

    ...the Cartesian dualism of "objective" and "subjective", of "fact" and "value", was just so much imaginative fancy... ...because we now realize that there are no uninterpreted data, that merely deciding what counts as data ("facts") is a matter of interpretation

    Not convinced. The realm of objective fact may be a little fuzzy around the edges, but that doesn't mean that there is not a useful distinction (between objective and subjective) to be made.

    I'm not convinced either. You seem to be saying that there is no objectivity possible. And I don't really understand the basis for what you call creative evolution or evolutionary creationism, which seems to me to be a form of wishful thinking or attempt to reconcile in some way that feels good to the intelligent Christian what the early Bible says about God's involvement in the development of humans and everything else with what we have learned about this process in the last 150 years. This is fine, it even feels good to me -- but I'd have to admit that this position seems just as fanciful (though much more empirically acceptable) than resolutely denying on scriptural grounds that evolution was and is the ongoing process by which creatures today have been and are being formed.

    But I guess I feel less need of any torturous reconciliation of Christianity to science --it concerns me less because of my (well-known to you, Todd) position on the reliability of Scripture.

    But that's an entirely different debate, and one we've had frequently.

    The hypothesis that God is active through "natural processes" is an interesting take on the question of theology and science, but at the end it seems to be only so much wishful thinking. By attributing "natural processes" to God, all one does is essentially say that God cannot be measured or detected in any meaningful scientific manner but for the sake of philosophical convenience His existence is assumed and His supremacy likewise postulated without empirical evidence. However, stating that the Deity works through "natural processes" gives Him a purloined patina of scientific respectability instead of the air of pure speculation He would otherwise be subjected to.

    To get more specific, which "natural processes" does God work through, and what are the indications that He does so? If there is no hard, measurable evidence along these lines, what makes this supposition anything more than the idlest of speculations?
     


    Posted by Todd (# 169) on :
     
    quote:

    That is precisely what I am saying, Laura.

    At least, not in the sense that "objectivity" is commonly appealed to in arguments like this. How can any system, whether religious or scientific or whatever, be objective in any thoroughgoing sense when the system's bases for inquiry are assumed axiomatically (as the assumption that nature and nature's processes are measurable and empirically verifiable)? Objectivity ends at the drawing of distinctions about what defines "objects" that are free of the mental phenomena that define subjectivity (as Russ has offered).

    And would you suggest, Russ, that mental phenomena exist in some ethereal realm that doesn't have physical existence (surely thought arises in part from neurochemical processes in the axons of our brains, even allowing for human consciousness as a property that isn't entirely reducible to those physical processes)?

    While I would agree that Jupiter (the planet) possesses a reality that my mental fantasies do not, I would suggest that the distinction of objective and subjective is considerably fuzzier than you are willing to grant.

    And Laura, I'm not quite certain what is so tortuous about believing that God's constant creative activity, geological and biological and cosmological, may truthfully be described as creation in a biblical sense, while also admitting that what science- geological and biological and cosmological- observes in unfolding nature is an evolutionary process, unable (though science is) to discern any ultimate purpose or meaning or goal in the process simply because that lies outside the purview of the scientific methodology that has rightly been adopted. Is there really such a suggestion of intellectual dishonesty as seems implied in your post?

    As for natural processes, Croesus, to take simply the example of evolution, I am not saying for a moment that God is using some natural process called evolution to create the cosmos. What I am saying is that what science describes as evolution is the creative activity of God.

    As to the indications that God works through what we describe as natural processes, I take the witness of the Hebrew Bible and the New Testament, as well the tradition of the Church that flatly states that God is at work in the cosmos, creating, revealing, and redeeming. As for "hard, measurable evidence" why should every way of human knowing subject itself to the narrow definitions of empirical materialism, definitions that make for solid methodology but make for metaphysics that is as dogmatic and unprovable as any foundational religious dogma?

    So much for infelicitous phrasing and fuzzy thinking.

    The division of objective and subjective is of course a real one, but not in the sense of there being objective and subjective ways of knowing. Objects are certainly real; the tree on my lawn that I can observe is certainly a real object. And just as certainly, the subjective is real; I, the observing subject, am also real. There is a reality outside myself (the subject), therefore the objective does exist.

    Quoting from Lesslie Newbigin,

    quote:
    It is surely obvious that knowing has both a subjective and an objective pole. It is subjective in that it is I who know, or seek to know, and that the enterprise of knowing is one which requires my personal commitment...And it is subjective in that, in the end, I have to take personal responsibility for my beliefs...I am responsible for seeking as far as possible to insure that my beliefs are true, that I am- however funblingly- grasping reality and therefore grasping that which is real and true for all human beings, and which will reveal its truth through further discoveries as I continue to seek.

    The Gospel in a Pluralist Society, p. 23.

    What does not exist is a sort of "objective knowledge" that is supposedly free of value judgments, of a priori decisions about what constitutes reality, of personal commitment. All those things that have been denigrated as mere "subjectivity" are really the only way that human beings have of understanding "objective" reality.

    I am going to post this, because I spent two taxi journeys and my half my lunch hour composing it, even though you have preempted what I have to say about 'natural' verses 'supernatural'.

    It will be clear to all from this thread that I am not an intellectual. I am not the clearest of thinkers and struggle to put my more intuitive ideas clearly. I pray now that this is clear, because what follows is an understanding of the root of the conflict between Science and Christianity.

    Having worked though the issues as they have been raised on the thread and read much populist material on the matter, as a theist, I now no longer have any issue with science or 'evolution'. In addition, I believe that ID falls short of both good science and a good theistic understanding of the nature of God. I need to clarify both these statements to show why there is no conflict between science and Christianity, and at the same time demonstrate why the conflict arises.

    Karl, you have often offered to list the evidence for 'evolution'. I would like to offer a summary which may fall short of the exact dates and events, and which you are free to correct. My understanding of the word 'evolution', in one sense is that the world is 4.6 billion years old. The earth cooled down and soon after that, about 3.8 billion years ago as shown by the fossil record, single cell life forms have been found to occur. 1.8 billion years ago more complex forms of life appeared. At some point around the Cambrian period a vast array of complex plants and animals appear in the fossil record and we know much of what happened, paleontologically speaking, since then. That is the broad understanding of 'evolution' and as I said, you may be able to correct me on the details.

    Taking that evidence we can all see 'evolution', the development, over a very long period of time, of complex life on earth. Is that a fair summary? Please tell me if I have erred in any way.

    Laura, you asked Todd if it all boiled down to the authority of Scripture. That's a half truth because our attitude to scripture and our attitude to creation boil down to a full understanding of the nature of God. Looking at the evidence for evolution set out above, we can see 'natural' processes at work, DNA replication and mutation, reproduction without exact copy, variation, speciation, potential for adaptation, Karl and others may well be able to add more to this brief list of natural processes.

    How do we understand God in relation to these 'natural' processes? Philosophical naturalists believe that God has no part to play in the working of 'natural' processes. They are 'natural' in the sense that they work without invoking the need for supernatural intervention. They are predictable because they behave according to the laws of nature. They are 'natural', not 'supernatural'.

    This mindset or view has 'evolved' over the last 300 years due to the initial assumption that the physical universe can be understood and, to a very large degree, predicted because it follows 'natural' laws. These 'natural' laws have become, in time, the focus for philosophical naturalists who believe that because the universe and life follows 'natural' laws, that there is no need for a 'supernatural' being to maintain or, perhaps, even create the universe.

    But to say that 'natural' processes exclude God is a corruption of a full understanding of God. If the product of chemical reaction or the course of a projectile can be predicted, does that mean that by following 'natural' laws, nature demonstrates the inactivity of God? By no means! A full understanding of God helps us to see that there is no difference between 'natural' processes and 'supernatural' except that the latter may be defined as a process which could not have been predicted by science. If I throw a ball in the air and it doesn't come back down to earth, but hovers for a second, does a couple of loop-the-loops and shoots off over a house, it would be described as a 'supernatural' event because it did not obey the predicted course of 'natural' events. But if I throw the same ball up in the air and it follows a parabolic curve (allowing for air resistance) which can be predicted by a mathematical model, it is said to be a 'natural' event, it does not mean that that God was not involved in that event.

    Philosophical naturalists would say that because it was predictable it was 'natural' and not 'supernatural'. Theists should say that there is no distinction between 'natural' and 'supernatural' because God is constantly operating in nature through his predicable, reliable nature. We can not theistically separate 'natural' and 'supernatural' events, though we can separate them as 'predicable' and 'unpredictable'.

    Therefore, 'evolution' as we have observed it, which is mostly predicable or 'natural' in that it has taken many billions of years for complex life to 'evolve' is not in conflict with the nature of God. What is in conflict is the thought that 'evolution' is a chance process, random mutation is not part of God's natural process or nature, but pure luck or survival of the fittest. But the 'natural' events of evolution part of God's action in creation, that is, they occur according to his nature.

    Theists are not at liberty to believe that 'evolution' is a chance, random, lucky, uncontrolled, purposeless, non-goal orientated process of 'natural' effects, because the 'natural' events can not be distinguished, in the eyes of a theist, between the predictable nature of God's work in creation and the times when God chooses to do something 'supernatural' that we could not have predicted by laws of nature. God is constantly at work, and 'natural' processes are the work of God, even though we can not detect his presence in this process empirically.

    My original question at the start of this thread concerning the effects of ID on our theology was coming at the argument from the wrong direction. It is not that ID will effect our theology but that we need to fully understand the nature of God to make sense of the work of science. It is our theology which must change first. Once we have a full understanding of the nature of God, science will be put in its proper place.

    To conclude, Crœsos, as you asked ' what makes this supposition anything more than the idlest of speculations', I'm afraid that you will not like my answer. The answer comes in the form of a question, 'Who was/is Jesus'? I have already posted a Christological basis for the fact that the material world is mute on the matter of faith in God. I encourage you to think about why that is while I spend another couple of taxi journeys and a lunch hour composing another answer.

    All the best

    The 'Wisdom Literature' of Proverbs, Ecclesiastes and the book of Job collectively shed interesting light on the matter of empiricism. Glenn may be wondering if picking an choosing scripture is legitimate, but my defense is that the verses are a summary of the overall framework, the big picture, the main thrust of scripture. The approach to empiricism starts with the premise that the universe is created by intelligence, that there is wisdom behind the material world, in Proverbs 8:27-31 Solomon puts it like this:

    quote:
    I (wisdom) was there when he set the heavens in place, when he marked out the horizon on the face of the deep, when he established the clouds above and fixed securely the fountains of the deep, when he gave the sea its boundary so that the waters would not overstep his command, and when he marked out the foundations of the earth. Then I was the craftsman at his side. I was filled with delight day after day, rejoicing always in his presence, rejoicing in his whole world and delighting in mankind.

    Solomon's description of wisdom stems from general revelation. Creation, conscience, love and beauty all form part of general revelation, that is that we can sense God by such things but that we can not prove that God exists by them. We no that God can not be proved by them, empirically detected, from Ecclesiastes 8:16-17:

    quote:
    When I applied my mind to know wisdom and to observe man's labour on earth - his eyes not seeing sleep day or night - then I saw all that God has done. No one can comprehend what goes on under the sun. Despite all his efforts to search it out, man cannot discover its meaning. Even if a wise man claims he knows, he cannot really comprehend it.

    If we are tempted to try to understand the meaning of what goes on under the sun, apart from God, we face the rebuttal Job faced when he dared to take on God.

    quote:
    Then the LORD answered Job out of the storm. He said:
    "Who is this that darkens my counsel with words without knowledge?
    Brace yourself like a man; I will question you, and you shall answer me.
    "Where were you when I laid the earth's foundation? Tell me, if you understand.
    Who marked off its dimensions? Surely you know! Who stretched a measuring line across it?
    (Job 38:1-5)

    Searching for empirical evidence of God in the natural world is a fruitless task, God has put it beyond our comprehension, 'despite all our efforts to search out its meaning'. This does not mean that we should not seek to understand the natural world around us. Indeed scripture encourages us to understand cause and effect so that we can learn to live better lives. Science is a natural activity for good Christian living.

    If the natural world can not reveal the purpose or meaning, where do we turn? If we see the big picture, the divine unity, the ongoing thread of God's work in humanity from our being brought into existence by God (100,000 years ago, correct me if that date is empirically wrong); our rebellion; the freeing of the people of Israel from slavery; God's care for his people in spite of their disobedience and deistic adultery; God constantly working to reconcile the his people to himself which culminates in his incarnation, human life, teaching, fulfillment of Hebrew prophesy and law; his unfair trial, unlawful conviction, unjust death, miraculous resurrection, ascension to heaven, divine rule and his future judgement, give purpose and meaning to everything under the sun.

    On the matter of purpose and meaning, what is the alternative? Here is an example of the best 'science' can hope for, strive for, gain purpose in, in a material world.

    The BBC World Service has once again provided a timely example of the vacuity of science without God. On it's program 'Science View', the BBC covered a story on the history of the relationship between humans and Mars. It was highly informative and an interesting summary the development of our understanding of the 'Red star' and the latter day search for life on Mars.

    It concluded with the following prophesy from Robert Zubrin, author of 'The Case for Mars'

    quote:
    The youth of today have a yearning for purpose. The message from Mars is, 'learn your science and you could become part of pioneering a new world'. As mankind emerged from the dark ages, Cathedrals were built as a symbol of purpose. How much more exciting will it be to be part of the establishment of a new cathedral to human purpose, the building of a settlement on Mars?'

    And then what?

    Todd - I'm not sure what you're trying to argue here. On the one hand, you are argue in favor of an objective reality and that you can make observations that trees or the planet Jupiter are "certainly" real. And then you argue that no such "certain" observations are possible due to your own human prejudices. Can you resolve this contradiction? It seems that you are arguing that statements like "the planet Jupiter exists" is equal in certainty and verifiability to statements like "green is a prettier colour than blue", since both are merely the products of individual, subjective prejudice.

    As for Neil's posts, it seems a case of assertions without anything to back them up. I could just as easily claim that my cat is responsible in some vague, unspecified, and mysterious way for all observable phenomena in the Universe, and I would have just as much evidence behind my claim. There are only two points in Neil's slew of postings that really bear commenting upon.

    The first is his continued antipathy towards probabilistic behaviour in any portion of the Universe. According to Neil's postings, anyting "chance", "random", or "lucky" is inherently unGodly. Given that such a deterministic viewpoint would invalidate not only most of genetics but also quantum mechanics and statistical thermodynamics, I think it only reasonable for me to expect a more in-depth explanation from him than simply his say-so. Or are you asserting that while certain events have probabilistic characteristics, biological evolution is somehow a "special case"?

    The other point I found interesting was Neil's assertion that "Science is a natural activity for good Christian living." This assertion is contradicted not only by most of the history of Christianity, but also by Neil's quotations from Ecclesiastes and Job which indicate an inherently incomprehensible Universe.

    The biblical understanding that ‘natural’ events (events which follow ‘the laws of nature’) follow the law under the omnipotent will of God is at least as valid, from the material observations, as the conclusion that no omnipotent being is acting, either that the laws, having been established, govern themselves (deism) or the conclusion that the laws ‘are’ and ‘do’ themselves (naturalism).

    All three conclusions stand on level ground on the basis of material observation alone. Indeed the idea that your cat controls everything is as valid on this basis as the three more common postulations.

    So why do naturalism and deism sit more comfortably with us today than theism? Could it be to do with our corporate philosophical understanding of nature? As I said, over the last 300 years, the methodological naturalism assumed for scientific investigation has become the justification for philosophical naturalism and deism. To our ‘scientifically’ trained minds, the idea of theism is quite repugnant. The problem faced by theism not the presence of supporting material evidence, but the conditioning of our minds by our education and culture to accept materialism.

    The difference between naturalism and theism comes when we confuse the way science can predict ‘natural’ events but can not predict ‘supernatural’. If science can not explain some phenomena, it is said to be ‘supernatural’. This is a naturalist’s label. As ‘supernatural’ events have exceptionally low rate of occurrence, and can often be explained by ‘natural’ methods, God becomes insignificant in our minds, an absentee landlord who cares so little for his creation he doesn’t even bother to intervene ‘supernaturally’ when things go wrong.

    But that is not the Biblical understanding of God. ‘Natural’ events are indistinguishable, theologically, from ‘supernatural’. That is, that every material event obeys God.

    The cells in our body work, not under our control, or under their own endeavours, but under the ongoing work of God, according to God’s nature. It is only the conscious mind which is at liberty to work against God’s will (and even that is a subject for debate – it needs another thread to discuss the Sovereignty of God and Human free will). ‘Evolution’ then, is seen by the theist to be the ongoing work of Christ in his creation. (Neo)Darwinism faces problems when gradual change is not evident in the fossil record, as admitted by Gould. Random mutation and natural selection are not sufficient to explain either the origin of life or, in light of the fossil record, the development of complex organisms in a short period of time. Intelligent Design is deism in another guise, because it tries to prove intelligence in design but is silent on matters of the sustaining work of God.

    But theism pulls all the evidence together and says, ‘as we find out new facts about how life develops on earth, we are witnessing the ongoing work of the God who made and sustains it all’. Forget about the muddied thinking of the church in the past, including YECism, we’ve covered the fact that all cultures have held fast to material philosophies as an understanding of how we came into existence. If we take a proper theistic mindset and look to the future, we can see that all future scientific discoveries will sit within a theistic framework and we will say ‘well done God, what a beautiful creation’. Sorry, I’ve used too many platitudes.

    I’ll end this rather long post with the following quotes from scripture which give the theological basis for understanding Christ as both the creator and sustainer of everything.

    quote:
    Hebrews 1:1-3 and 2:7-8
    In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven. You made him a little lower than the angels; you crowned him with glory and honour and put everything under his feet." In putting everything under him, God left nothing that is not subject to him. Yet at present we do not see everything subject to him.

    Colossians 1:15-22
    He is the image of the invisible (ie undetectable in creation) God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. He is before all things, and IN HIM ALL THINGS HOLD TOGETHER. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross. Once you were alienated from God and were enemies in your minds because of your evil behaviour. But now he has reconciled you by Christ's physical body through death to present you holy in his sight, without blemish and free from accusation.

    I think that one of the reasons that theism (or at least theism in the mold that Neil presents) sits so hard with us is the recognition that it is not just an unscientific belief system but that it is inherently antiscientific. Breaking with the notion that everything happens at the whim of some supernatural entity or entities was the first step on the road to science. Such supernatural explanations have a stifling effect on scientific inquiry for two reasons. First, if everything has the same answer intellectual laziness is fostered. Imagine the sorry state of scientific knowledge if the following answers were regarded as complete and sufficient.

    quote:
    Q: What causes typhoid?
    A: God.

    Q: What causes the photoelectric effect?
    A: God.

    Q: What makes fire burn?
    A: God.


    Which leads to the second reason such an attitude is dangerous. These so called "answers" attributing these and all other phenomena to a mysterious being or beings don't actually answer anything at all. Saying that something called "God" is responsible for fire, or the photoelectric effect, or typhoid tells us nothing about these phenomena.

    Unfortunately I can't "forget about the muddied thinking of the church in the past" because the same thinking and attitudes are still common in the Church today. These include the notion that material, scientific evidence should be subordinate to theological philosophy and, in cases of disagreement, scientific evidence should be ignored in favor of theological expediency. This attitude is shown time and again in religious opposition to evolution, or heliocentrism, or medical anesthesia. What seems to be going on here is a sort of "effectiveness envy", with religious thought being jealous of the fact that science is so good at producing unambiguous, material results. Indeed, this sort of feeling can quite clearly lead to a sour-grapes sort of attitude and eagerness for giving science some sort of comeupance, such as Neil's statement that "science will be put in its proper place" someday.

    Your imaginary questions stop well short of the activity of science under theism. I have stated that science is not at conflict with Christianity, if science is viewed as the activity of understanding how things work. The conflict arises when science tries to explain more than how things work (like typhoid and fire) as Dawkins puts it

    quote:
    Science shares with religion the claim that it can answer deep questions about origins, the nature of life, and the cosmos, but there the resemblance ends. Scientific beliefs are supported by evidence, and they get results. Myths and faiths are not and do not.

    Your imaginary questions stop short of science under theism, because theists are not prohibited by a Biblical understanding from investigating the world, theists are encouraged to do so. Kisten Birkett puts it like this

    quote:
    It should be clear by now that the Bible is in favour of investigating the world. It is God’s world, after all, and it is only appropriate that as caretakers of his world we should be interested in how it works. Anyone who takes the Bible seriously has excellent motivation to take up science, if he or she so wishes.

    What is more, we have motivation to take up science through the empirical method. While there is not space here to go into the complexities – or the historical background – the biblical understanding would lead us to think that empiricism is an appropriate method for investigating the world. That is, the Bible shows us that God acts in the world the way he wants to. He has not given first principles from which we can deduce logically how the world must be. The only way we can discover how the world is, is to look at it. The only way to find out how it works, is to investigate it. If we are interested in how the world is put together in a functional sense, we do not simply ponder in our heads, or wait for revelation from God – we go and use our senses and our brains to find out.


    That is science in its proper place.

    While it may "be clear by now that the Bible is in favour of investigating the world" to Ki[r]sten Birkett, the rest of us are left wondering since Neil apparently left off prior paragraphs containing the explanation. Given that his scriptural quotations at 23 August 2001 04:21 were blatantly anti-scientific (a point which I made a full day ago and he has not yet denied), perhaps he could come up with a few contradicting scriptural passages that actually encourage scientific investigation. If the empirical scientific method is something God would want to encourage, there must be a scriptural passage describing scientific methodology somewhere in there.

    I have come to what I regard as a sufficient understanding of this issue having wrestled it through on this thread, and learnt much in the process. I've been spurred to read supporting books from every angle (Dawkins, Gould, Lewontin included). Family life demands more of my attention, so I will no longer contribute to the thread.

    I have enjoyed having to think about many issues, and hope you have too. I do not have time to answer your point about the passages I quoted being anti-scientific, which they are not. They were concerned with wisdom, the fear (respect) of God being the beginning of such. If you are truly interested in knowing what the passages are about, you can readMatthew Henry's Commentaryas a starter for 10. If you were only interested in picking a fight for the sake of it, then all the best, I wish you well with future debates on science and Christianity, unnatural enemies.

    All the best

    One last post, which has been on my Palm Pilot for about 4 weeks. It needs to be posted to conclude the debate that we didn't have.

    We have covered on this thread the fact that philosophical naturalism is the view of the natural world which supports and is supported by secular humanism. This is indeed the case according to the Council for Secular Humanism's own webpage

    quote:
    We believe the scientific method, though imperfect, is still the most reliable way of understanding the world.

    If the western paradigm is currently post modern, why does our law only consider the secular humanist position? Is it because secular humanism allows individual religious freedom, but restricts that freedom in the shaping of ethics and law? Secular humanists say it is so:

    quote:
    As secular humanists, we are generally skeptical about supernatural claims. We recognize the importance of religious experience: that experience that redirects and gives meaning to the lives of human beings. We deny, however, that such experiences have anything to do with the supernatural…We consider the universe to be a dynamic scene of natural forces that are most effectively understood by scientific inquiry.

    So God is kept firmly in place by science. Morals, ethics and law are shaped by relativism. Again, the Council for Secular Humanism says,

    quote:
    There is an influential philosophical tradition that maintains that ethics is an autonomous field of inquiry, that ethical judgments can be formulated independently of revealed religion…We are opposed to absolutist morality, yet we maintain that objective standards emerge, and ethical values and principles may be discovered, in the course of ethical deliberation.

    All was well for secular humanism, until now. The opening line of their statement says:

    quote:
    Secular humanism is a vital force in the contemporary world. It is now under unwarranted and intemperate attack from various quarters.

    So, secular humanists are aware being 'attacked', where is the attack coming from and what is being attacked? The attack being referred to is the work of scientists who no longer believe philosophical naturalism is a viable position.

    The 'attack' has commenced with the undermining the very belief structure of philosophical materialism. Some scientists now claim that nature demonstrates general revelation. It is not that God can be proved by empirical means, but that the material world appears to be the product of wisdom, that it is designed, and that it is not just a product of undirected natural forces.

    The 'heat' between philosophical theists and philosophical materialists is not regarding unscientific practice or method. The 'heat' is generated because philosophical naturalists, secular humanists, do not wish to consider the possibility of the divine, or more probably, moral absolutes.

    Philip Johnson covers this matter in his is two books, "Reason in the Balance: The Case Against Naturalism in Science, Law, and Education." and "Objections Sustained: Subversive essay's on Evolution, Law and Culture". 'Reason in the Balance' is introduced thus:

    quote:
    According to Naturalism, God has no place in law, science, or the schools. Naturalistic thinking rules the intellectual world, including the public schools, the universities, and the elite of the legal profession.

    But is naturalism itself beyond question? Few among the cultural elite have dared doubt it. Now comes Phillip Johnson, Berkeley law professor and former clerk to the U.S. Supreme Court, set to take on the "intellectual superstitions" of the day.

    After this book, the culture wars may never be the same again.


    If secular humanism, then, is seen to be a faith based position, and not based on the 'fact' of naturalism, then secular humanism has no more legitimacy than other faith based positions to govern, dictate law and shape education.

    This is what I hoped we could speculate on at the start of this thread, because it is not just the legitimacy of secular humanism but much if not all of last century's liberal theology which has its neck on the block. No wonder no one wanted to debate or consider the possibility that God had anything to do with nature.

    Objects are certainly real; the tree on my lawn that I can observe is certainly a real object. And just as certainly, the subjective is real; I, the observing subject, am also real. There is a reality outside myself (the subject), therefore the objective does exist.

    What does not exist is a sort of "objective knowledge" that is supposedly free of value judgments, of a priori decisions about what constitutes reality, of personal commitment.

    All those things that have been denigrated as mere "subjectivity" are really the only way that human beings have of understanding "objective" reality.


    Todd,

    I rather suspect that the tree you can observe on your lawn has objective existence. Can it not be observed by anyone, regardless of their value judgements, personal commitments ? Could a rational person conceivably take a prior decision that trees don't exist and thus be completely unable to perceive it ? Seems to me that we are sense-equipped to perceive trees and therefore perceive them whether their existence be consistent with our philosophy or not.

    However, there may also be on/within your lawn much tinier plants that one would only perceive if one set out to look for them. It seems to me that they have exactly the same kind of objective existence as the tree, but because of their scale, they have a different relationship with human beings. Our relationship with them is such that our philosophy and interests may be relevant to whether we perceive them or not, or act on the perception if we do. ("That doesn't count as a weed, it's too small").

    Some perceptions are preceded by a decision of the observing subject as to what to pay attention to. Some perceptions arrive unsought.

    Seems to me that you're miffed that the methodological naturalism (wonderful phrase - thanks Karl!) of science appears to grant to God merely a second-class existence as a subjective phenomenon alongside visions, illusions, philosophies and ideas. And are therefore moved to attack, inaccurately, the foundations of science.

    How dare science belittle religion !

    Croesus,

    You seem to be taking the opposite tack. Having agreed that the scientific method will never detect the existence of God, you seem to see no reason to postulate a God at all.

    Why doesn't religion just lie down and die now that science is here to explain things?

    Can I suggest that the importance to us humans of values and purposes are not diminished by the fact that they are unscientific ? And that you might be better of approaching religion as being about values and purposes, and not about explaining things in term of the existence of supernatural entities ?

I'm raring to write a critical review of Darwin's Black Box by Michael Behe and to highly praise Kenneth Miller's excellent Finding Darwin's God (thanks for the recommendation Karl).

    But I find that Neil has changed his mind about intelligent design and has signed off the thread (after a colossal amount of writing on his part - thanks for the thread Neil). Never mind it was fascinating reading for its own sake, not just for debate!

    Ah well, I'll post my review over the weekend and I will also take up Neil's comments that:

    I know Neil's signed off, but maybe someone else can help me. I don't see how secular humanism is a faith-based position (and I used to consider myself a secular humanist -- in those days I would have cringed to hear it described as faith-based).

    As for who is attacking secular humanism, I have long been under the impression that folks who want to post the Ten Commandments in classrooms and courtrooms are the kind of people mounting serious attacks on secular humanism, not scientists who say rational materialism is not the be-all and end-all of human inquiry and knowledge.

    RuthW - I think it depends on how you define "faith". It's a slippery and ambiguous term. It can either mean "belief in the existence of something" or "belief in the rightness of something". By failing to resolve this ambiguity, much confusion is engendered.

    Unless I've misunderstood him, Todd's not denying that at all. He's not denying that the tree has an existence outside his mind, he's simply noting the fact - surely uncontroversial - that anything we know or understand about that tree is, precisely, stuff that we know. The knowledge therefore, whilst being knowledge of an object that is really, objectively there is, inevitably, subjective knowledge. There is no other kind to be had.

    This doesn't lead to non-realism, it doesn't lead to solipsism - it's been a bedrock assumption of most philosophy since Kant.

    Knowledge is not a perfect reflection of external objects on the flat, blank screen of our minds. It is, always, already interpreted: raw data arranged and categorised and interpreted by our brains in all sorts of complex and subtle ways. In that sense, our minds have always already influenced and shaped what we think we see.

    Mike,

    Tell me more.

    You agree that the tree is objectively there. Are its leaves objectively green ? Is it objectively taller than the garden fence ? In what if any sense are its properties determined by the characteristics of the subject who perceives it ?

    If it is objectively both green and taller than the garden fence, is the statement that the tree is both green and taller than the garden fence not an objectively true statement ?

    Whereas the statement that the tree is very pretty can only be subjective, because it refers to the subject's perception of the tree and not the tree's objective characteristics.

    I really don't see the problem.

    If I convey to you a photo of the tree, or a description of the tree, such an image will inevitably be incomplete, yes. And in choosing to describe it in a certain way or photograph it from a particular angle I will have made an editorial judgement. Depending on my background I will find some aspects of the tree more worthy of comment than others.

    But that doesn't seem to me a reason to deny the distinction between objective and subjective.

    Am I missing something obvious here ?

    Russ

    Welcome back, I hope you had a great holiday. I've decided to quit the thread because this matter was occupying a disproportionate amount of my time. I look forward to your post about Behe/Miller and I will redouble my efforts now to find Miller’s book in Singapore.

    I’m also interested to hear your views about the separation of church and state. You might like to read The Council for Secular Humanism's (TCfSH ) Declaration one more time before posting, because this issue is tied up with the legitimacy of any one position for dictating the rules, and TCfSH say that their legitimacy is based on science.

    TCfSH item two calls for the separation of church and state:

    quote:
    Because of their commitment to freedom, secular humanists believe in the principle of the separation of church and state. The lessons of history are clear: wherever one religion or ideology is established and given a dominant position in the state, minority opinions are in jeopardy.

    What is Secular Humanism if it is not an ideology? Why does it deserve a dominant position in the state?

    RuthW, if science can neither prove nor disprove God, then what is Secular Humanism’s religious scepticism based on? Faith.

    This and the next two postings are some of my responses to the arguments (and to the style!) of Michael Behe’s book Darwin’s Black Box , which I read recently. I will try to be brief since his arguments have been criticised on this thread and elsewhere. (See in particular Robert T. Pennock’s Tower of Babel ; Kenneth R. Miller’s Finding Darwin’s God. and Allen Orr’s review ‘Darwin v. Intelligent Design (Again)’ at the Boston Review website.)

    Behe’s argument.
    The living world is full of complicated things. Evolutionary theory tends to explain the existence of these complex things by saying that they ‘have been formed by numerous, successive, slight modifications’ (Darwin). People like Richard Dawkins have shown how such gradual changes can in principle explain the evolution of complex organs like the eye. Behe wants to move the argument down to the molecular level.

    To Darwin’s generation trying to see what went on at the level of the cell was like looking at an opaque, black box. Molecular biology has opened that box up in the last fifty years and revealed incredibly complex systems and structures inside the cell. Behe says that many of these cannot be explained by gradual evolution. (He makes great play of how no one has come up with complete step-by-step accounts of how these systems evolved - and nothing less will satisfy him.) He concludes that such systems must have been designed by an intelligent agent; since it is so massively improbable that any could have sprung into being fully formed, in one event.


    Response
    In response: the detective work involved in reconstructing the origins of biochemical systems that came into existence over perhaps a billion years is considerable! Seeing that we have only recently begun to understand how these kinds of systems work it is unreasonable to expect people to be able to reconstruct their origin and evolution so soon! Nevertheless some progress is being made and, for example Kenneth Miller shows how Doolittle's account of the evolution of blood clotting is far more persuasive than you would imagine from reading Behe’s book.

    Miller also describes other ways of coming at the problem. He tells of experiments with bacteria that show that they have a remarkable ability to evolve complex systems. In addition Pennock discusses computer programs that have been set up to have random variation, plus reproduction, plus selection and have resulted in the evolution of complex virtual ‘creatures’ that had not been dreamed of by the writers of the programs. These are thus not designed features but emergent features of the running program. Both these approaches reveal that random variation plus natural selection is in principle capable of a great deal more complexity than one might think.

    Behe and ‘Irreducible Complexity’
    Behe tries to argue that a particular type of complexity is particularly hard for gradualistic evolution to account for. He calls it ‘irreducible complexity’. A structure or system is irreducibly complex if it consists of parts that work together to achieve a function but where if any one of the parts is missing it that function is lost.

    Behe wants to say that such systems are unevolvable because you cannot select for them bit by bit: you need all of the components for it to function. But he admits that they could evolve in an indirect way. This is exactly the criticism that Orr levels at Behe. Behe just does not explore the idea that ‘Some part (A) initially does some job (and not very well, perhaps). Another part (B) later gets added because it helps A. This new part isn't essential, it merely improves things. But later on, A (or something else) may change in such a way that B now becomes indispensable. This process continues as further parts get folded into the system. And at the end of the day, many parts may all be required.’ Nor does he consider Dawkins comments that some systems have lost previously essential elements as others have been able to work without them (we might deny that an arch could be built stone by stone if we ignored the possibility that there was support or scaffolding – now gone- used in its construction).

    Instead Behe contents himself with arguing that ‘as the complexity of an interacting system increases though, the likelihood of such an indirect route drops precipitously (p40)’. This is just not true, all it means is that the route would take a longer time, and with many of the basic molecular systems having taken a billion or so years to evolve a long time was available.

    Behe's Darwin's Black Boxcontinued... (the posting after this is more fun)

    Double standards about analogies
    One aspect of Behe’s book that I found particularly irritating was that Behe appears to have a double standard when it comes to the use of analogy in arguments. He uses one rule for evaluating his own (just mention the similarities) and another for his opponents (focus on the differences).

    For example on p218 Behe says:

    quote:
    Analogies always are set up so that they … propose that A is like B in a restricted subset of properties. Rust is like tooth decay in that they both start from small spots and work outwards, even though tooth decay takes place in living materials, is caused by bacteria … A Rube Goldberg machine is like a blood-clotting system in that they are both irreducibly complex, even though they have many differences. In order to reach a conclusion based on an analogy, it is only necessary that the deduction flow out of the shared properties. [My italics].

    Yes, but one has to ask: ‘how does one prove that the deduction does really ‘flow out of the shared properties’?’ You cannot prove it by the analogy itself because you are then arguing in a circle. For example, to argue that ‘This helium filled balloon floats in air, therefore this helium filled gas cylinder will float in air too’ proves that floating flows from the shared property of being filled with helium is obviously wrong. Differences in properties may frustrate the shared ones.

    So when Behe says, following on immediately from the last quote:

    quote:
    The irreducibly complex Rube Goldberg machine required an intelligent designer to produce it; therefore the irreducibly complex blood-clotting system required a designer also.

    As an argument from analogy it fails unless independent grounds can be given for the assertion that irreducible complexity is impossible without design. Given that Behe has admitted that ‘one can not definitively rule out the possibility of an indirect, circuitous route’ for evolving such systems (p 40); and that ‘there is no magic point of irreducible complexity at which Darwinism is logically impossible’ (p203) he must judge the argument to fail.

    Just a page later (pp219 to 221) Behe chucks his own insights into analogy overboard by criticising Sober and Dawkins’ use of the set of lettered discs which eventually produce the words ‘ME THINKS IT IS A WEASEL.’ Does he see that the analogy of this system with evolution rests on the shared properties of random variation plus non-random selection? No! Instead he launches into a list of how the system described differs from evolution in that the system has no function, has an intelligent agent doing the selecting etc. In doing so he reveals how completely he misses the point.

    But there is worse: both Sober’s and Dawkins’ accounts of this analogy explicitly point out that it is not a complete analogy for evolution. Does Behe mention this? Not at all! I found this the most offensively crass and polemical section of the book!

    When Behe’s opponents make analogies between one thing A and another B, he is very quick to highlight the differences between A and B. But when it comes to his own he is less than scrupulous. For example he constantly refers to the cell as a machine, which lulls the unsuspecting reader into being more receptive to comparisons of the molecular systems with mousetraps and Rube Goldberg machines and so on. Why does Behe not point out that the cell is vastly unlike a machine? Machines do not reproduce copies of themselves; do not compete for resources; do not have parents; are not subject to natural selection. Machines are also designed – a nicely covert way of assuming the point in dispute.

    Sure, use the example of the (intuitively unevolvable) mousetrap to explain irreducible complexity, but why not then discuss the eminently evolvable Venus Fly trap – nature’s version! Sure, talk about Rube Goldberg machines, but ignore the fact that they are nearly always linear, consist of elements that are vastly different from each other, and generally involve great complexity to perform a simple function. And when you compare it to blood clotting do give due weight to the fact that the system is not linear; the elements are very similar proteins, the function is complex all of which have bearing on its evolvability.

    Behe's Darwin's Black Box continued... the shorter, more fun responses.

    Behe misrepresents Dawkins
    I can’t say everything that I would like to about Behe’s book Darwin’s Black Box but I can’t overlook his misrepresentation of Dawkins. Behe says (p249) that:

    quote:
    In the Blind Watchmaker Richard Dawkins tells his readers that even if a statue of the Virgin Mary waved to them, they should not conclude they had witnessed a miracle.

    Dawkins comes across from this as an irrationally fanatical atheist. In fact Dawkins says no such thing. He explains that the probability of this happening by chance is unimaginably huge, but calculable. He also says that if he was struck by lightning after saying ‘may I be struck by lightning this minute’ he would regard that as a miracle. Since he states that the lightning stiking him after uttering that sentence is, at 250 trillion to one, vastly more probable (and hence less miraculous) than the statue waving I find it incredible that Behe can misrepresent him in this way.

    Some annoying rhetoric form Behe
    Behe indulges in lots of rhetoric (FAR too much to record here) but some bits that especially annoyed me were:

    P97 ‘Doolittle … deserves a lot of credit for being one of the very few - possibly the only person – who is actually trying to explain how this complex biochemical system arose’ (Message: see how science ignores these problems!) Unfortunately Behe forgets that he has already written on p89 that: ‘Several scientists have devoted much effort to wondering how blood coagulation might have evolved.’

    P172 ‘In private many scientists admit that science has no explanation for the beginning of life.’ (Message: see how science hushes up these problems!) But take a look at Behe’s footnote and it turns out that (p283) by ‘in private’ he means published ‘in the scientific journals’!!!

    P232-3 ‘The results of these … efforts to investigate the cell … is a … cry of “design!” The result … must be ranked as one of the greatest achievements in the history of science. The discovery rivals those of Newton and Einstein …’
    The reader’s first thoughts might be ‘then is Behe to be ranked with Newton and Einstein?’ But wait a second, they both produced highly original and detailed theories that explained reality in radically perceptive ways. Behe in contrast is just holding his hands up and saying ‘I can’t explain this complexity and I bet no-one can!’ That is hardly in the same league of genius!

    I enjoyed your posts. Behe does have many flaws in his form of argument. Although, may I say, that your critique was written in the usual rhetorical form that most authors, on all philosophical sides of this matter, adopt. It is not that your arguments were fallacious, but that you concentrated, as a lawyer might, on flaws in Behe’s argument. Turning to what first interested me about Behe's book, what do you think about the bio-chemical challenges on the formation of ATP which I asked Crœsos about earlier, and to which he has posted no response?

    Neil
     


    Posted by Glenn Oldham (# 47) on :
     
    Thanks Neil, I am glad I did not bore everyone to death!

    Yes you are quite right, I guess I did rather adopt the lawyer’s style of questioning the opposition case but not offering an alternative (Pennock criticises Johnson for doing that in his books). One has to start somewhere though! I am hoping to say a bit more of constructive nature in a later (and shorter!) posting about Miller's book.

    In the meantime however, you have raised the question of Adenosine Mono Phosphate (AMP) which Behe covers in chapter 7 of his book. As you know he discusses problems with the idea of metabolic pathways evolving with a particular look at AMP. He points out that AMP is needed to make DNA and RNA. He might have spelled out that this leads to a circle: the AMP needs the enzymes to form; the creation of enzymes depends on their being encoded for in the DNA or RNA; and the DNA needs the AMP to form itself. That’s fine and dandy if the system is set up but how do you get it started? He does raises various similar questions about how the interactive and complex pathway for AMP could possibly evolve gradually.

    Behe sets out the view of Creighton writing in 1993 that a pathway converting A to B then B to C then C to D may well have evolved from D being present naturally to begin with, then, when it became scarce cells able to make it from C would have an advantage, and cells that make that from B would do even better and so on (p151).

    But to cut to the chase: I think Horowitz’s idea is on the right lines for at least some metabolic pathways. I think de Duve’s ideas, about protometabolic pathways and of catalysts that catalyse a number of reactions, are also along the right lines. What I would emphasise is that Behe has looked at the pathway for AMP synthesis that exists now. Yes, that pathway may be a couple of billion years old, but it probably evolved and changed extensively over a period of half a billion years or more before that. The original pathways are probably very different from what they are today. Intermediates and catalysts that used to be involved probably no longer exist.

    As you may know Cairns Smith in Seven Clues to the Origin of Life has proposed that the first replicating and selectable things on earth were very likely not RNA or DNA based systems. What originally functioned in a ‘genetic’ way was not RNA or DNA (no need for AMP at that stage). (Dawkins discusses Cairns Smiths ideas in The Blind Watchmaker ) He proposes other possibilities and suggests the idea that a great deal of evolution of such systems took place before RNA or DNA began to be used for coding purposes but that, once it did, it took over the function because it was so much better at it. On this model it is thus highly likely that the original metabolic systems were also very different from what they are now. And on this model some path for AMP production probably came into existence from these earlier metabolic systems before RNA and DNA got going.

    As for his discussion of regulation of the rate of reactions Behe does not once mention the fact that reactions – even catalysed ones - have their own equilibrium states (the proportion of A to B in the conversion of A to B for example). Nor does he mention that the extent of the reaction (its equilibrium state) would be amenable to natural selection too, often on a gradual rather than all-or-nothing basis.

    Working all this out is going to take science some time, and it may even be that the truth is lost in the mists of the remote past some 3.5 to 4 billion years ago.

    Which leads me to remark that Behe did irritate me in the way he harps on again and again along the lines of ‘no one has a clue’ about how this or that system evolved. But what is he doing when he discusses the ideas of people like de Duve and Doolittle if not reporting the clues that they think they have and are following up? He irritated me again when he seems to think that he can dismiss de Duve’s work by saying that he fails to put names to the chemicals in his protometabolic pathways. But how do theories begin if not with speculation? It seems that not only has Behe no time for step by step evolution of life he doesn’t have any time for the step by step formation of a theory – he wants the full, complete and detailed thing to spring forth fully formed! Instead of being sent forth to encounter and benefit from criticism and ideas from others first.

    Could life have come into being through gradual evolution? Well the evidence for evolution is very strong, the fossil record, homologous structures in different species, DNA finger printing correlating so well with classification of animals and plants arrived at by other means, etc. Given all that, evolution seems to me the best explanation we have at the moment. Sure we don’t know how to explain all the details but Behe’s alternative of some primeval cell with a colossal genome with all the information in it later organisms would need won’t work. The genes that were not expresses would not be kept in working order by natural selection. As a result a couple of billion years of copying error and accidental deletions would have wasted them away and turned what remained of them into nonsense. Thus the genes for the clotting mechanism would have wasted away long before the animals they serve so well came on the scene.

    By the way, Pennock has criticised Behe’s ch7 Groundhog metaphor. His book ( Tower of Babel- a critique of the new creationism ) is one you may want to look at because of his long critique of Johnson.

    Thanks again for a thread that has proved so stimulating. I see that it has offspring in the ‘Objective and Subjective’ thread, I wonder if that too will evolve!

    Best wishes,
    Glenn

    Many thanks again. You have evidently thought through Behe's work at length. You said

    quote:

Well the evidence for evolution is very strong, the fossil record, homologous structures in different species, DNA finger printing correlating so well with classification of animals and plants arrived at by other means, etc. Given all that, evolution seems to me the best explanation we have at the moment.

    I agree that the development of life was gradual, and that 'evolution' is the term applied to gradual development. But, with this view in mind, I have two questions to ask. Firstly, what did you think about the ‘natural’/supernatural’ as opposed to ‘predictable/unpredictable’ concept?

    That was to say that theists see no difference between ‘natural’ events and ‘supernatural’ (a philosophical materialists’ term) because there is no difference…God is always active, sustaining his creation. The only difference from our subjective perspective is whether we could have predicted the way God acted in an event. If we could not have predicted it, we call itsupernatural. But to exclude God from the ‘natural’ event is not theism, it is deism.

    Under theism, it doesn’t matter if ‘evolution’ was gradual or rapid, whether it could have been predicted by Darwin’s scientific theory (ie that ‘evolution’ was the predictable action of God in nature) or not. What matters is that God is in control of every action, the terms ‘natural’ and supernatural do not apply, because there is no distinction. Everything we see around us in science is supernatural, because God is involved, we just forget it because almost everything is unpredictable’, such is God’s nature.

    Secondly, would you agree with the view that Behe et al are not doing science (as defined as understanding the ‘predictable action of God in nature, but that they are indulging in a commentary of general revelation? That is that God is evident through his creation. Behe can see the wonder of creation at a microbiological level, and has turned it from a commentary of the wonder of it all, into pseudo-science.

    Any comments?

    which is basically where I'm coming from with "theistic materialism", science being a description of that activity (which is predictable because God is faithful).

    quote:

    I would say that many good scientific (ie "natural") explanations are descriptive rather than predictive. I don't know anyway that we could say, had we been around, that certain dinosaurs would evolve into birds; but the fossil record does describe that.

    I would accept that God does, occasionally, work in ways outside his normal practice; these are miracles. I think much that is called "supernatural" could have natural explanations (some hauntings may be purely psychological for example) although the use of the term for things which are genuinly beyond any reasonable chance of natural explanation is fair enough. I think I'd like to invent another word to describe things of God; that is "meta-natural", completely beyond natural (transcendant would do, but has deist connotations).

    Just a few more thoughts,

    Alan

    Which is part of what I was trying to get at when I mentioned that a Christian worldview helped to foster the development in modern science. The Christian God is not some whimsical deity who can't be relied on, but a God described as "faithful and true". Therefore, it can be expected that the natural world will be governed by law.

    quote:
    Such supernatural explanations have a stifling effect on scientific inquiry for two reasons. First, if everything has the same answer intellectual laziness is fostered ... These so called "answers" attributing these and all other phenomena to a mysterious being or beings don't actually answer anything at all.

    and again, the expectation that being made in the image of God humanity can understand how the world works means that better answers could be found. To call the deeply religious founders of modern science in western Europe lazy because they believed God was ultimately responsible for the way the world works does a great disservice to them, and all the other Christians who have devoted their lives to science since.

    quote:
    the same thinking and attitudes are still common in the Church today. These include the notion that material, scientific evidence should be subordinate to theological philosophy and, in cases of disagreement, scientific evidence should be ignored in favor of theological expediency.

    unfortunately you are right, some (often very vocal) elements in the Church do show such an attitude. However, it hardly seems fair to tar all Christians with such a brush because of the activities of a small minority. I fear, that no matter how much I would like to change things, people showing such ignorance and stupidity is a part of life.

    Neil,
    Thanks for your questions. I have only time for brief replies after sitting up far too late into the small hours posting earlier this week (I see more clearly why it is called ship of fools)

    quote:

    Firstly, what did you think about the ‘natural/supernatural’ as opposed to ‘predictable/unpredictable’ concept?

    Yes, I agree with you, excluding God from being connected with natural events and relegating him to only supernatural events is not a theological stance I would approve of. The way the universe is is to some extent an expression of God. Of course applying the term ‘expression’ to God is inevitably metaphorical. I dislike too much emphasis on the natural/supernatural distinction for other reasons too. It can lead to an undervaluing of what we call the natural; and it lends itself to readily to seeing God in too anthropomorphic a way.

    Miller has some speculations about God’s relation to the world involving the inherent indeterminism of quantum events which I hope to comment on and which seem promising.

    quote:

    Secondly, would you agree with the view that Behe et al are not doing science (as defined as understanding the ‘predictable action of God in nature, but that they are indulging in a commentary of general revelation?

    Yes. I think that to the extent that Behe and his colleagues stop looking for how physical laws (or ‘law like regularities’ if one prefers that expression) might be able to explain the development and origin of complex biochemistry, then to that extent they have stopped doing science on those problems.

    I understand that part of their research and work is devoted to developing a good theory about how to distinguish intelligent design from design arising from physical laws. I have no objection to this research being seen as science. I do not know much about their ideas on this, however.

    Finally, while we have fairly clear ideas about what is involved in a human designing something, God designing the universe is unique and must be a very different affair, as well as having enough similarities for the word design to be appropriate.

    Oh no it is after midnight again!

    22:26 Singapore time...this needs to be quick.

    I like the idea of using 'meta-natural' as a term to describe the 'unpredictable'. There is a job to somehow convince Joe Public that God is active, even though naturalism has come to define a world without God.

    Is there any truth in conclusion that assuming naturalism for science has led to a closed loop where philosophical naturalism is true because the naturalism (predictability) of nature proves that philosophically naturalism is true? If so, how do theists begin to demonstrate the flaw in the argument?

    I said it would be quick

    Having seen the error in Behe's argument, from a theological perspective rather than empirical angle, I may have left you and Alan with the impression that I accept 'evolution' as fact. I would like to point out that I do not accept 'evolution' as fact, from both a theological perspective and empirical angle. Why? Empirically, it is a theory with more gaps than my granmother's teeth. Theologically, random, purposeless and material results in deism not theism.

    To illustate this, I have come to the end of Romans 11 in my study and meditation this morning, and add the doxology from verses 33 to 36 as a fitting summary of theism and why Christianity and science are therefore unnatural enemies.

    quote:
    33 Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out! 34 "Who has known the mind of the Lord? Or who has been his counselor?" 35 "Who has ever given to God, that God should repay him?" 36 For from him and through him and to him are all things. To him be the glory forever! Amen.

    According to this doxology, ‘evolution’ can not be random, purposeless and material because God is at work in his creation (from him) at all times sustaining it (through him) and one day it will all come to an end and we will meet with him (to him) either, in the context of the preceding chapters, as God’s elected people or as objects of God’s wrath.

    Whether ‘evolution’ was continuous or whether God designed it intelligently or acted in ways which science could not predict (given that science is the gathering of empirical evidence for the predictable nature of God) at points such as the development of self-replicators or the sudden development of complex life form in the pre-Cambrian explosion, or whether it was all made 10,000 years ago is merely squabbling over pennies. The big picture is that God made it all, sustains it all and will judge it all.

    Neil, I thought we'd done this already? Never mind, I'll say it again. Evolution as a scientific theory has no place for purpose, it is merely descriptive of what has happened in the past and prescriptive of the mechanism by which species evolve (I don't think any biologist would predict what new species they'd evolve into). If you extend the purposelessness of the scientific description into a philosophical position then you are left with having to accept either deism (God started things off but doesn't really care where they go from there) or atheism. You can also have a deism where the physical laws and initial conditions of the universe are such that intelligent life must develop, and God sits back to watch it happen, which does introduce an element of purpose but I find unsatisfactory.

    However, the view expressed by myself and several others, which I have called theistic materialism, is very different from these views. This is theism, with God intimately involved in his creation, upholding and sustaining it. From a materialistic (ie: scientific) perspective the universe appears to run by laws, and evolution has no apparent purpose; science still works to give us increasingly improved understanding of the material world as it actually is. However, at the same time we can say philosophically that there is purpose and meaning, and also that there is more than just the material. Thus, God can truly be the one from whom, through whom and to whom are all things.

    quote:

    Agreed, in the scheme of things the method of Creation isn't as important as the fact of Creation, and especially not as important as the Christ event. However, in public perception the "conflict between science and Christian belief" is a major problem, creating the impression that we check our brains in at the church door. Thus, this is a big issue.

    As to the gaps on evolutionary theory, I don't know how ancient the rest of you are but back in 1975 when I was 20 and doing a biology degree there were a lot more gaps then than now!

    Over the intervening 26 years we have been able to find out how similar the genes are in organisms, that genetic fingerprinting shows organisms to be 'related' in just the patterned way you would expect from evolution. We have found out about hox genes and their efffect on development and that they are in us as well as fruit flies.

    Evolutionary theory has enlarged too and new ideas about sexual selection and other aspects have been put forward and tested out.

    So the gaps were there, some are there still but many have been filled. Rome wasn't built in a day. Exploring all the ramifications of a theory takes a long time.

    A French publisher friend in Singapore gave me a book by landscape photographer Ric Ergenbright, called The Art of God (1999 – Tyndale House Publishers, Inc, Illinois – not to be confused with the British Tyndale House). At the time, I flicked through the photos and put it with other big books on the shelf in the living room. I took it out last night and read the narrative. Here’s an extract from the introduction which points to the beginning of the paradigm shift we have discussed on this thread:

    quote:
    The seed for this book was sown in my childhood…gazing at the heavens and pondering the eternal riddles of life. How far is infinity? How long is eternity?…Over and over we would pose and ponder the questions, then discard them in frustration until the very next night.

    Childhood summers soon faded into adolescent memories…My gaze turned inward and my view of God grew dim as faith born of natural observation was exchanged for scientific dogma learned by rote. Seeking to please my teachers and avoid the ridicule of peers, I dutifully parroted Darwin’s mantra and denied God the glory of His creation. New discoveries would often rip embarrassing holes in the fabric of macroevolutionary theory, but my pride kept me from seeing the philosophical nakedness they revealed. I simply trusted that science would patch the holes and validate my belief. The holes kept getting bigger, requiring narrower blinders and greater faith to avoid seeing the obvious.

    …I began reading the Bible. Gently but steadily the blinders were pulled back, until I could no longer deny the truth before me: the perfection of everything in the heavens and on earth could only have come from the mind of an all-knowing, all –powerful, all-loving Designer, and never from an eternity of time plus chance.

    Thanks for that non-answer, Neil. Again, what are these alleged bloody great holes in 'macroevolutionary theory'?
     
    Posted by Glenn Oldham (# 47) on :
     
    I said that I would like to comment on Kenneth R. Miller’s book Finding Darwin’s God. (Cliff Street Books/ HarperCollins 1999).

    In short, this book shows (contra Ric Ergenbright view in Neil's most recent post) how evolution does not rob God of his credit for the glories of creation.

    Karl recommended this book, and what a good book it is. I would put it at the top of my list of books to recommend to any Christian wanting to consider the issue of evolution and its religious implications. (Closely followed by Pennock’s book The Tower of Babel )

    Miller’s book is in three main parts. The first is two chapters that introduce the topic and which give a brief history of the theory of evolution and the evidence for it.

    The second part consists of three chapters that critique various creationist viewpoints. ‘God the Charlatan’, looks at Morris and Whitcomb’s ideas of a young earth and contains the best short examination of radioactive dating that I have come across. The Rubidium/Strontium test is compelling and compellingly described. ‘God the magician’ looks at the evidence against the idea that each species was separately created. ‘God the mechanic’ is a very good critique of Behe’s book Darwin’s Black Box.

    There is then an interlude chapter that looks at ways that some atheists have tried to use evolution as evidence against religion. He points out that these writers have and assumption in common with the creationists, namely

    quote:
    that … if the origins of living organisms can be explained in purely material terms, then the existence of God – at least any God worthy of the name - is disproved. (p190)

    ‘What I propose to do next’ says Miller ‘is to ask if that assumption is true.’ This he does in the final three chapters of the book. This is the final and constructive part of the book in which Miller expounds the ways that evolution is compatible with Christianity and religious understandings of the world.

    Christian critics of evolution tend to loathe the idea of randomness involved in evolution. Their alternative is to see the world as one which is essentially deterministic (to avoid randomness) but in which God interferes (to avoid deism). Miller points out that modern physics no longer sees the world as essentially deterministic, and, in Ch 7, he points out that the mutations that underlie evolution occur at the atomic level and therefore involve quantum effects. Quantum theory appears to show that randomness and uncertainty are built into the fabric of the universe; they are part of God’s creation. The universe is one in which natural laws and chance are inextricably mixed together. Miller explores the idea that this kind of world is one for which a more satisfying model for God’s action and for our own is possible than for other kinds.

    He quotes Polkinghorne:

    quote:
    The actual balance between chance and necessity, contingency and potentiality which we perceive seems to me to be consistent with the will of a patient and understanding Creator, content to achieve his purpose through the unfolding of process and accepting thereby a measure of the vulnerability and precariousness which always characterizes the gift of freedom by love. (p242)

    … and Barbour:

    quote:
    Natural laws and chance may be equally instruments of God’s intentions. There can be purpose without an exact predetermined plan. (p238) [My italics, G.O.]

    From the perspective of the debate in this thread Miller rejects the idea of seeing God’s design in terms of inexplicable features of the universe in the way Behe does, he sees Gods design in a larger sense of being responsible for the basic structure of the universe and the quantum uncertainty in its nature. He covers other issues than those I have mentioned including some comments on evolutionary psychology/socio-biology.

    The title of the book comes from Millers appreciation of the spirit of what Darwin said at the end of On the Origin of Species:

    quote:
    There is a grandeur in this view of life; with its several powers having been originally breathed by the creator into a few forms or into one; and that, whilst this planet has gone on cycling on according to the fixed laws of gravity, from so simple a beginning endless forms most wonderful and most beautiful have been, and are being evolved.

    All in all this is an excellent and stimulating book. Thanks again Karl!

    I hope to check out Keith Ward’s Religion and Creation sometime too, since he usually has an astute appreciation of science and his book may bear on this topic.

    There is no safer time to flog a horse than when it is dead.

    This particular horse having turned up its hooves ('hoofs' is also correct) nearly a year ago, now is a good time for me to report on a very good book on the subject of this thread.

    Intelligent Design Creationism and its Critics: philosophical, theological, and scientific perspectives. is edited by Robert Pennock (MIT Press 2001). It contains 37 articles from 25 authors and has over 800 pages of text. It contains papers previously published and some written especially for the book. The principle protagonists on the creationist side are Behe, Dembski, Johnson, Plantinga and Paul Nelson. There are lots of replies to their arguments and some replies to replies. It covers many of the issues raised in this thread such as irreducible complexity, naturalism (methodological and no-methodological types), teaching creationism in schools and much more. I especially enjoyed the discussion and critique of Dembski's views about 'specified complex information' Peter Godfey-Smith's is a very clear and powerful refutation of Dembski's argument. I also found illuminating the discussion about whether or not the results of comparing the genomes of different organisms tells for or against evolution.

    I found it extremely readable and fascinating and, to my surprise, read it in less than a fortnight. At £30 it is expensive so it is best to think of it as four 200 page books at £7-50p each to realise its value for money.

    Answering the original question on this thread 'how would the failure of the theory of evolution' effect our theology, the answer to the question can be found in the opening essay and preface to two of the arguably most influential liberal theological works of the last century or so.

    From 'Faith' in Lux Mundi
    quote:
    When for instance, men see their habitual reliance on the evidence for design in nature, which had been inherited from Paley, yield and vanish under the review of the facts with which the theory of evolution aquatints them. What they feel is, that their familiar mode of interpreting their faith, or justifying or picturing it, has been abruptly been torn from them.
    [as an aside, note the supremacy of feeling or experience, in liberal theology, rather the rationalism so often sited by liberals as the leg to the three legged stool of scripture-tradition-reason. There's a thread in this...liberal theology is concerned primarily with the supremacy of experience, not reason.]

    And John Hick in the preface to The Myth of God Incarnate.
    quote:
    Western Christianity made two major new adjustments in the response to important enlargements of human knowledge. It accepted that man is part of nature and has emerged within the evolution of forms of life on earth.
    We need not ask the question, it has already been answered. Much, if not all, liberal theology would be written off as an irrelevance, a vacuous fallacy, if the theory of evolution were superceded. There's evidently more at stake than belief in the origins of life.

    Now, I'm not a real expert on liberal theology, being an evangelical an all, but I don't see evolution as foundational to liberal theology (any more than Creation is foundational to evangelical theology, much as some people would seem to think it is).

    Apologies for the following generalisation. Taking the "Reason, Tradition, Scripture" tripod, by and large liberals would emphasize Reason more than other theological positions. As such, they would be more open to learning from and incorporating the fruits of Philosophy, Science etc... So, yes, I'm sure evolutionary thought has influenced liberal theology. But if (and as we've covered in depth here that's a very big if) evolution is found to be an imperfect scientific description of the origins and development of life and is superceded by a better scientific theory (which, in my opinion, will not be either Creationism or Intelligent Design) then I'm sure liberal theology will adapt to the new understanding.

    Alan

    You said that liberals would adapt their theology to suit any new theory of the development of life and that is exactly my point.

    In the quote from the essay 'Faith' by Rev H.S. Holland in Lux Mundi, he contrasted Palley's design with Darwin's evolution and decided that his faith as a Christian minister had to change because evolution had demonstrated, in his limited experience, that nothing is designed. I assume that any subsequent change in theory would lead to a change in theology. But God doesn't change because we change our theories, surely?

    Now, you mentioned 'reason' as the supreme authority for liberals but I used the term 'experience' deliberately, as liberal theologians are supremely concerned with experience and not reason. You'd need to read 'Lux Mundi' or 'Honest to God' to begin to see why liberals are experiential not rational. It has much to do with not being experts in any scientific field and so retreating to a defensive theological position defined by a subjective experience which could not be detected by empirical means. Safe ground, but lacking in potency for evangelism.

    The reasoning went like this:
    We have the comprehensive family trees of a particular organism - lets say the Nautilus, so we know what all it's ancestors - trilobytes - were and what the branches of the 'evolutionary' tree look like.

    If we find something we know has been a product of intelligent design, then do its family tree and then compare this to the family tree of the Nautilus, if the two match then Nautilus is a product of intelligent design.

    So the guy took his enormous collection of cornets (small trumpet for those not in the know), grouped them by age and design features, then ran them through his genetic algorythm software which then spit out the family tree of his cornet collection.

    Surprise surprise, it looked nothing like the tree of the Nautilus. This was because one manufacturer had a good idea, and then all the others appropriated it - this made the tree very flat with multiple branches from one node (rather than the 2 branches you'd expect in an evolutionary tree)

    So, ipso facto evolution is correct, Intelligent Design is wrong, God is proven none-existent.

    That seems to me to be a very fatuous piece of scientific research and the author has made some big leaps and assumptions which seem to me to be un-scientific in the extreme.

    Frankly, you might as well go looking for the primal cause in the Register of Patents.

    The first two clauses are OK - if evolution is correct then Intelligent Design is wrong. It does not, of course, follow that if evolution is right or ID wrong that God is proven non-existent.

    The guy has a point, it may be reasonably expected that ID and evolution would result in differences in the family trees of organisms. In that sense he's pointed out a potential test to falsify ID. That he illustrates this with an inappropriate example, cornets, is a shame - but I'd think if he tried it on actual organisms he wouldn't be able to illustrate any difference. This would, of course, be because proponents of evolution and ID could quite easily look at the same organism as an example of both evolution and ID so the same family tree is consistent with both. What would be needed would be a sufficient understanding of both evolution and ID to draw up theoretical family trees and compare them to actual organisms - though I don't think either are in a position to do that at this time.

    As an aside, I've put some brief thoughts on Design Theory on my website. Those who've read all this thread (and if you haven't, why not?) will realise that I don't really think that highly of ID.

    I appreciate that the existence of God cannot be surmised from either of the first 2 clauses - the article didn't, in fact, make any opinions on the existence or otherwise of God. That bit was my own sarcastic irritation at the article.

    Whether we are intelligently designed or evolved is almost a side issue to the original post - I find it hard to believe that a scientist could claim to have proven any one theory defunct by looking at another case which is its fairly removed analogue.

    Are my own leanings towards the existence of God (and therefore intelligent design/theistic evolution) forcing a bias of my opinion, or is this fellow lacking scientific rigour?

    ..or possibly both.

    There are two questions. Does God exist? and How did life develop? Problems happen when people try and answer one by looking at the other.

    I suspect your anger comes from your suspicion that the Scientist in question isn't really interested in evolution but is trying to disprove God. You've sort of admitted that you're not interested in how life developed but would like to prove God exists. Neither approach is going to get either question answered to anyone's satifaction.

    I trust people who are genuinly interested in questions of life's development to come up with explanations. Similarly I'm spending far too much time on this board because I think you people are genuinely interested in God.

    Incidently with my purely scientific hat on I don't even believe in myself. [Yipee]

    quote:
    Unlike the swivel-eyed creationists, ID supporters are very keen on scientific evidence. They accept that the earth was not created in six days, and is billions of years old. They also concede Darwin’s theory of microevolution: that species may, over time, adapt to suit their environments. What Intelligent Design advocates deny is macroevolution: the idea that all life emerged from some common ancestor slowly wriggling around in primordial soup. If you study the biological world with an open mind, they say, you will see more evidence that each separate species was created by an Intelligent Designer. The most prominent members of the ID movement are Michael Behe the biochemist, and Phillip E. Johnson, professor of law at the University of California. They share a belief that it is impossible for small, incremental changes to have created the amazing diversity of life. There is no way that every organism could have been created by blind chance, they say. The ‘fine-tuning’ of the universe indicates a creator.
    I know that Creation vs Evolution has been kicked around these boards until is a very dead horse indeed. However, I'm not a scientist and would be interested to hear from Shipmates who are if a)there really is a big swing away from Darwin and b) if there is anything in ID?

    [Full Version]

    The fact that the same names - Behe, Dembski, Ross, Johnson come up time and time again shows there is no swing against Darwin. There're a few religiously motivated individuals, but no groundswell, no swing.

    ID itself is no more than a revised God of the Gaps fallacy. Take Behe's book Darwin's Black Box. Essentially, his thesis is:

    (a) some structures (example: bacterial flagellum) are "irreducibly complex" - take a bit away, and they don't work;
    (b) darwinism can't explain how an irreducibly complex structure can arise;
    (c) therefore God mustadunnit.

    Quite apart from the logical fallacy of placing God in a gap in current knowledge that may be filled tomorrow, there is the problem that Behe's examples are only irreducibly complex in the context of their current function. Kenneth Miller has done a lot of work on Behe's examples and is the person to read - once again, I heartily recommend his book Finding Darwin's God. He goes into some depth on the blood clotting cascade, on which not only has a possible evolutionary pathway been proposed, but also molecular evidence gathered to support the theory. You can follow it here http://www.millerandlevine.com/km/evol/DI/Clotting.html

    I would suggest ID is ultimately damaging to faith. When the gaps in which God is placed are closed, God becomes homeless. It is also scientifically flawed. "Ah, Goddidit" is not a scientific hypothesis. The scientist must ask "OK, then how did God do it?"

    Nice succinct answer there Karl.

    Also, I liked the last paragraph of that article
    quote:
    St Basil, the 4th century Archbishop of Caesarea in Cappadocia, said much the same thing ... If an Archbishop living 1,400 years before Darwin can reconcile God with evolution, then perhaps Dawkins and the ID lobby should be persuaded to do so as well.
    Which of course also introduces the fact that extreme evolutionists like Dawkins, IDers and YECs fall into basically the same trap of expecting science to be more than science is. Science provides materialistic descriptions of the material universe ... to push it into metaphysics is a misunderstanding of both science and metaphysics.

    It is a good article. I was glad to see that the "no transitionals" PRATT was addressed - the most cursory glance at Archaeopteryx tells you it is the perfect reptile/bird transitional, and attempts by creationists of any stripe to discredit it as such are invariably highly amusing.

    What's less well known is the amazing series of transitionals that links reptiles to the first mammals. The apparently difficult feat of replacing the reptile jaw joint with a mammalian one and migrating the reptilian jaw bones into the middle ear is shown in graphic detail through the therapsid series. (go here: http://www.talkorigins.org/faqs/comdesc/section1.html and do a search for "therapsid" on the page)

    And, one of the objections mentioned in the article is quite valid
    quote:
    The playwright blamed the doctrine of survival of the fittest for ‘capitalist misery and the oppression of the people’.
    Which is a confusion between Darwinism as an theory of the origin of species by natural selection acting on genetic diversity with some of the more whacky extensions of the theory to aspects of sociology and politics. It's no more valid to criticise Darwinism for this than say criticise Special Relativity because you disagree with notions of relative morality.

    What Karl said the first time.

    The second one is a bit dodgier - Behe's "intelligent design" really is the "God of the Gaps" brought in to explain stuff we have no good theory on. But it is not irreconcileable with the observed universe the way YEC is.

    To follow Dawkins analogy of a historian annoyed by people who claimed that the Roman Empire never existed & all the apparent evidence is faked.

    YECism is like saying that ALL of known history is faked. That the whole world came into existence about 100 years ago and the stuff your grandparents told you that their grandparents told them was all lies. If you believed that then history would be a pointless excercise.

    Behe-style ID is like saying that the Roman Empire did exist, but the usual account of its origins were wrong - instead of being founded by Augustus in a coup against the Roman Republic, it was all down to a secret society of Illuminati, who left no records which can can understand.

    One concern I have about science is that in some circles it has become a religion in itself.Our understanding is more important and we exalt ourselves out of a faith.

    I am encouraged that people can have a living vibrant faith whatever they believe regarding creation

    But you can see my dilema between what I have learned and what I believe

    The only thing I can say is that I look at the world today and cannot accept that all this was down to a chance explosion -

    at school the science teacher stood back when teaching creation v evolution and let the class discuss it - the only thing I had was to keep on going back and asking people who believed in the bang - what happened before - and kept on asking that question to each theory they cmae to explain that one away -

    I presume that noone is advocating that God was not involved in making this world or do we take out the first three verses of John 1 as well.

    I did have to subscribe to a flood to tie a lot of it together - including why plates are moving - there have obviously been changes on this earth even after the fall given that Methuselah lived till he was almost 1000 in yet I have to be happy with my threscore years and ten.

    Firstly, if you understood the 'big bang' theory you'd understand that this is a senseless question.

    Secondly, even if it weren't a senseless question, God doesn't provide an answer to it. God is not the beginning of a chain of events. God is not 'before' in a literal sense. God is outside of, and the creator of, time. There is a difference between the doctrine of Creation - which asserts that God is the reason why there is something rather than nothing at all - and temporal cosmological explanation. Hence, holding that the universe has no beginning, as in steady state theory, is compatible with belief in Creation.
    (St. Thomas Aquinas asserted something similar - holding that believing the world had always been there didn't do violence to faith in God or his Creation, but rejecting the idea because scripture claims the world has a beginning.)

    I take it that you mean you couldn't reconcile a particular interpretation of Genesis 1 with what you were being taught at University. I studied physics, with a dash of geophysics, at university and I'm now working in a lab where other people do a lot of dating working. I have no problem because I don't believe Genesis 1 is a literal historic account of what happened; it is a symbolic statement of the theological truth that God created and some elements of the nature of the world we live in (eg: it is ordered and coherent because it's the work of a single God who brings order out of chaos).

    quote:

    I'm not a Biblical Inerrantist, but if you read the Biblical Inerrancy thread here in Dead Horses you'll find that there are Inerrantists who would agree with my reading of Genesis 1 (more or less) - Inerrancy doesn't compel you to accept Genesis 1 as a particular literary style, yuo can beleive it to be an inerrant non-historical account.

    quote:
    I think it is a cop out by some that a day is like a thousand years and that they were not physical days - but have to say that the evolution debate will not be resolved till this world ends.
    I'd agree that saying the "days" are infact longer periods of time is a cop out. For a start, it still disagrees with what science tells us about the world. It introduces long periods of time, but things are still in the wrong (and indeed, illogical) order.

    I'm more optimistic than you about a resolution to the "problem". I believe that the picture portrayed by science, of a geology and biosphere that has changed gradually over long periods of time in accordance with phenomena as currently observed, is how God actually created the world we live in. The opening chapters of Genesis tell us those important details about Gods involvement and purpose that science is unable to tell us, but says nothing about the mechanism or time scale of creation.

    quote:
    One concern I have about science is that in some circles it has become a religion in itself.
    Which is an entirely different discussion, and a point I expect I'd probably agree with you on. But it's a mistake to read the likes of Dawkins and think he speaks for all scientists on the philosophical matters (on the other hand, his descriptions of the science of genetics and evolution are excellent).


    quote:
    I presume that noone is advocating that God was not involved in making this world or do we take out the first three verses of John 1 as well.

On almost every American board I've gone to, where I've argued for a figurative reading of Genesis One, I have had my faith questioned. It's always implied that if one trusts God sufficiently, there will be no need to ask questions...even when a literal reading and one's knowledge of science leads to contradictions.

    I have found that I can't 'will' myself to believe something that I know isn't true. (I feel that is what I am being told I have to do to be a good Christian, by these people.) [Frown]

    So I'm still seeking an acceptable harmonization of Genesis with modern cosmology- I hope that such a thing is possible. [Smile]

    I'm only jsut wading into this debate, so i'm sorry if i'm repeating someone else's thoughts, but if you're trying to reconcile genesis to science you're in for some trouble.

    If you study the original Hebrew language, you'll find it's not a "scientific" language, unlike the Greek which is far mroe scientific in structure and form, and the genesis account (at least the first dozen chapters or so) is even more poetical in its form than the rest of the Old T (with the exception perhaps of psalms / SoS)

    The Hebrew genesis was written as a "why" rather than a "how". there are numerous patterns and imagery within it. It even contains a not so subtle dig at the the Babylonian account of creation (if you've studied a little of that as well). The ultimate purpose of the creation story was to say, regardless of how it was done, that God was behind it, and to set out the pattern by which we were intended to live out our lives.

    I agree. Does this help at all:

    "The Jewish sages also tell us that God dances when His children defeat Him in argument, when they stand on their feet and use their minds. So questions...are worth asking. To ask them is a very fine kind of human behavior. If we keep demanding that God yield up His answers, perhaps some day we will understand them. And then we shall be something more than clever apes, and we shall dance with God." (Mary Doria Russell, The Sparrow)

    What do you think of the gap theory ie there was a space of time between the world being created and man coming onto this earth?

    It is interesting the freedom people have to interpret scripture - from taking things literally to taking things figuratively / spiritually.

    I still have a 7 day hang up - but it has to be a matter by faith and not based on science - I do like Martyn Josephs line in saying that sometimes we should treasure the questions - it is not wrong that I have doubts and holes in my understanding - but I know that we look through a glass darkly now ...

    Personally I'm not directly involved in dating work. The other half of the research group I'm in does do some luminescence dating, and I do help out with some radiation measurements for that work. Within the rest of the lab there is some C14 work (both dating and environmental studies, and an AMS facility for that work has recently been built) and a whole load of radioactive and stable isotope geochemistry, and does some dating work.

    I'm not sure what you mean about progression from radiocarbon. For most of the dating of geological relevance C14 is inappropriate anyway, as C14 dating only works for samples of less than about 30-40 thousand years old. The use of AMS has enabled accurate dates to be determined from much smaller samples, and we recently had a talk on progress into various reservoir effects (where the source of carbon in an organism has a different isotopic ratio from the atmosphere - for example in marine environments).

    Of course, there have been more suitable dating techniques for geological systems for many years. These include K-Ar, Rb-Sr and U-Pb dating, which allow accurate dates for samples going all the way back to the formation of the earth some 4.6 billion years ago.

    Let me refer all of you to the excellent talk.origins website, where years and years of discussion are archived. There are many excellent links there, including

    Another site I found through a web search is RadioMetric Dating: a Christian Perspective which reviews the 40 or so methods used.

    I never said, nor intended to imply, that carbon dating is in any way inaccurate. For suitable samples (less than about 50000 years old) carbon dating is accurate, though at some points on the calibration curve uncertainities of maybe as much as a few percent occur. There are additional uncertainties associated with corrections to the calibration curve for marine samples to account for the regional variations in 14C concentrations in water and in some locations these variations are poorly defined.

    quote:

    In most cases the initial concentrations are well known. The 14C calibration is based on comparisons between 14C dates and dendrochronology (tree ring counting) which effectively measures the atmospheric 14C concentration over time. If you look at K-Ar dating then the samples dated are usually volcanic (or otherwise heated to high temperature), with the hot rocks allowing Ar to escape setting the Ar concentration to zero which then increases as K decays.

    quote:
    Some of it being based logarithmically which could mean millions of years out in some cases
    Radioactive decay follows an exponential curve. That doesn't make it unaccurate, at least not for samples younger than about 10 half lives of the decay being used. For 14C that is 5730 years, giving the maximum usable age of about 50000 years.

    quote:
    but that is to say that I do not know much about dating
    Indeed, I suggest if you want to discuss the question you find out some more. There are plenty of good websites out there that will explain the techniques - try for university sites, rather than just Creationist sites.

    [ETA: I see you don't even need to Google for them]

    Not more accurately. Covering different timescales or rocks, and hence better suited in some situations.

    Well its quite accurate. Usually within a couple of hundrd years out of a few thousand - it can sometimes be calibrated by tree-rings, lake varves & so on, so we have good data.

    But it has no relevance at all to evolution because it only works for recent objects, the last ten thousand years or so.

    yes it could. But a few million years out of hundreds of millions is quite accurate really

    Carbon dating is only relevant for newish stuff, and only relevant for things that were once alive (like wood or bone). It can sometimes be calibrated by tree rings or varves which are probably exact - so we really do have good dates from it.

    I may (and probably am) way out of my depth on this issue, but I have spent a fair bit of time reading from both sides of the debate, and despite being a Pentecostal, have managed to keep a fairly open mind ;-)

    My question to anyone that cares to answer has to do with something someone on this board called macro-evolution. The example I'll use has to do with your average mammal's vision.

    If we start somewhere around the mammal's point in evolution where sight did not exist, then assume that one part of the visual system, for example the retina, appeared first. So here we have a spot, somewhere at the front of this creature, that does nothing. At this point, the creature can't see, because the retina, unless backed up by the 5 other sub systems involved in the visual system, does not provide the creature with sight.

    My question is, why, as a natural part of the evolutionary process, would this spot persist while all the other components of sight came together, if it had no apparent benefit for the creature in question?
     
    Posted by Alan Cresswell (# 31) on :
     
    Well, mammals started off with decent eyes anyway. But, to address the general query, eyes developed from photosensitive skin. This has an evolutionary advantage over no photosensitive skin in that if something passes between you and the source of light you know about it - that could be a predator (so you can take avoiding action) or prey (which could be lunch). Then, if that patch of skin were inside a slight dimple in the skin there's potential information on which direction the shadow is coming from ... and before too long you get a rudimentary eye.
     
    Posted by Karl: Liberal Backslider (# 76) on :
     
    There are a number of animals that do just have a patch of photosensitive cells. It seems to give them an advantage.

    The Irriducible Complexity argument, which is what we have here, makes a number of mistakes. One of them is assuming that unless it worked the way it does now - i.e. a camera eye producing a sharp image on a retina - it would confer no advantage.

    The eye is, of the structures in the natural world, perhaps one with the best extant set of transitional forms.

    Thanks guys, I appreciate your responses, but my lack of understanding begs me to ask another question.

    How does a patch of photosensitive skin transmit data to the brain, unless there's a connection? And if there's a connection, did that develop at the same time as the skin? Don't we come back to the irreducibly complex argument?

    And Karl said this:

    I understand that, and see the flaw in the argument, but looking at the way the eye does work now, in that all the sub systems must be functioning in order for sight to be possible, how did it get to where it is? Please don't think I'm trying to argue with you here, just trying to get my head around it.

    Greetings, and first off I have to say that it is impossible to construct a theory based on the scientific method that could even remotely explain design or a designer.

    How could you falsify that?

    So far there is no theory at all to dispute evolution and common descent.

    If so please name one that follows the scientific method?

    As time progresses more and more evidence exists to enforce evolution as a fact. You would have to intentionally close your eyes to avoid the landslide of evidence that exists and supports the theory of evolution.

    Secondly you need to drop the term Darwinism, there is no 'ism' to it. It's not mythology, it's science, Darwin didn't make this up, he discovered it.

    If you'd like some real evidence of evolution seeing how most who don't believe in it know absolutely nothing about it.

    When the mammals first evolved they had eyes!

    Macro-evolution is not the term, it's called Common Descent.

    Structures are passed on to the next generation and built upon therein. Evolutionary theory predicts that all structures will follow this pattern.

    'If you have, you will know that Darwin’s theory of natural selection as a means for explaining the origin of life and the origin of new species is coming under increasingly objective scientific criticism.'

    But it still stands as the undisputed answer to the observed phenomena.

    There is no other currernt theory, no falsifications have been presented to believe otherwise.

    I must add that the theory of evolution DOES NOT, explain the origin of life, it simply details how life works to adapt to it's ever-changing environment. That's a common theme and typical of people who do not understand evolution.

    Nothing in biology makes any sense without evolution, you'd have to discount every biological science there is if evolution were wrong. Currently there is nothing that makes evolution wrong.

    Just a bunch of statements like 'they have evidence it's wrong!' yet no one ever presents any.

    'they' is a common cop-out, you can make statements all day long that include 'they' which details no science or proof in your statement.

    Just like evidence that supports god, there is none and no current theories to explain it.

    Please back up what you say with some form of scientific proof.

    Well, there are plenty of "data transmission channels" between the skin and the brain that don't relate to sight - just put your hand on a warm surface and you'll experience the effect of some of them.

    quote:

    Skin is only present in larger organisms of course, bacteria being single cells don't have a layer of skin cells. It developed over time to allow larger oganisms to both protect their inner organs from the outer environment and to interact with that environment. I'm pretty sure the second of those would have required some form of communication of signals from the skin to whatever nervous system the organisms have. So, yes, skin and the communications system developed together. Nothing irreducibly complex there.

    It got to where it is by the process of several small steps, each of which was an improvement on the earlier version and so gave a survival advantage. The same as any other feature developed. Another thing is, we have living examples of all the basic steps along that line of development (in some organisms and environments the cost of developing more complex eyes outweighs the benefits gained and so the intermediate forms are the best suited and are retained).

    The most primitive creatures with such a patch do not even have brains. Once you do have a central nervous system, there's no real difference between a nerve ending that fires when it experiences touch and one that fires when the cells it's attached to respond to light. And remember, all we need here is "Ooo! Light source this way!"

    To answer this, we need to ask which stages you are questioning.

    Eyes in nature include pits containing light sensitive cells (more directional than just a patch), pits with very small apertures (pinhole cameras that start to focus actual images) and eyes where the aperture is larger but has a rudimentary lens (better than a pinhole in low light). Once you get muscles round the aperture to squash and flatten the lens, the rest is garnish. [Biased]

    Some (relatively uncontroversial statements):
    1. Dawin was a very thoughtful man
    2. Dawinism died in the the last century and was replaced by Neo-darwinism.
    3. Neo-darwinism explains the origin and diversity of the species in the following way:

    Random mutation is always occuring. If a mutation offers a selective advantage (ie. it makes an animal more likely to survive and/or reproduce) it is selected for. This is natural selection which is entirely 'anti-random' as Dawkins puts it.

    So far so good.

    The problem is (and I speak as one with a degree in molecular biology) is that it doesn't work. Before I go any further let me say two things: 1. I've read Behe's book - it is very good and explains the problems with Neo-dawinism very well; 2. I am very nervous of any scientific argument and resutls in the philosophical 'God-of-the-gaps.' The God of the bible is intricately involved in his creation and not simply there to explain what science cannot.

    Having said that, Neo-darwinism (evolution as it is currently understood) does not explain the origin or species.

    How can I make such an outrageous claim? Well Darwin himself knew that his theory (and the subsequent more sophisticated theories) depend on a stepwise mechanism and that anything in nature that could not be arrived at in a stepwise manner would be the downfall of his theory.

    There are so so so many biological mechanisms that cannot develop in a stepwise manner.

    The eye seems to be a popular battle ground for this debate. One says I don't see how an eye can evolve - look at it; it has a lens, a retina a nerve and muscles etc. And the reply quite acurately points out that even some light-sensitive cells would confer a selective advantage and the rest is simply improvements.

    This argument is flawed because (as Behe) makes very clear there is nothing simple about a light-sensitive cell and it requires many many proteins to work. And so for a cell to become light-senstive is the problem.

    Let me explain further- (I'm sorry to everyone who already knows this, and this is a simplified version).

    Proteins are the stuff of life - Genes code for proteins. Each protein is made up of building blocks called amino-acids. The gene simply determines which building blocks go together is which order to make a particular protein. Proteins are incredibly variable. There are 20 different amino acids and haemoglobin, for example has over 100 of them (in each subunit) and that's a small protein.

    Neodarwinism works like this - A mutation occurs in the DNA. This then makes a novel protein, this protein gives some advantage to the organism and then is selected for. Thus the species evolves. Different conditions make different things beneficial hence fish have gills and birds have wings.

    OK. Mutation occurs all the time. (Although all higher organisms have mechanisms to correct mutations). The vast majority of mutations do not make any difference. A small number are deadly. An even smaller number are beneficial. But to get a novel protein is difficult.

    The theory goes that if you allow enough time then a mutation that is useful will occur and thus be selected for.

    Here's a bit of degree level genetics: An experiment you can do with bacteria goes like this. If you put E. coli (bacteria) on an agar plate it will grow. If you put ampicillin in the agar (an antibiotic) the E.coli won't grow. If the E.coli has an ampicillin resistance gene added to it, this strain of E.coli will grow even on the ampicillin plate.

    Okay the experiment is this; A simple molecular technique is used to inactivate the ampicillin resistance gene. Then the E.coli is spread on the plate containing ampicillin. What we expect is no growth - we've switched off the gene needed to allow the bacteria not to be killed by ampicillin. What you get is some growth - but very very little. This is because at a rate of 1 in 10 to the power of 7 ie: 1 in 1000000 the bacteria spontaneously reverts - that is by random mutation it switches back on the gene for resistance, this clearly has a selective advantage and so only the mutants grow.

    So far so good. But coming back to the eye: light sensitive cells require multiple proteins to work; if they required two: the chances of getting both mutations is 1 in 10 to the power of 14. And that is an underestimate for two reasons - 1. the spontaneous revertant explained above is a simple mutation and not reflective of nature and 2. you need at least 9 proteins for a light-sensitive cell to work. So the chances of it happening are (much higher than) 1 in 10 to the 63. And you need each of the nine proteins before you have any advantage for the organism for natural selection to work on.

    And there are countless examples of cellular mechanism that depend on multiple protiens in order to work.

    I'm not yet sold on the design hypothesis, but as a scientist with an open mind I have to say that Neo-darwinsim does not work on the molecular level. Hence it cannot be true. The fact that I cannot offer a replacement theory does not mean I have to accept one I know to be wrong.


    Congratulations to anyone who got to the bottom of this. I promise this is a simple as I could make it. [Snore] [Confused] [brick wall]

    As I recall, some single-cell organisms have primitive "eyespots" - euglenids which as basically pond-scum.

    Does the euglenids eyespot require two proteins? That page implies that it's unexplored territory.

    I'd assume (at some chance of making an "ass" of "me") that the eyespot is a modified chloroplast. If the two proteins the previous poster referred to include chlorophyl (is that a protein?), which is useful in itself - then there's no problem.

    I trust that Alienfromzog has read Ken Miller's writings on Behe's IC argument - i.e. that the irriducibly complex structures that Behe describes aren't.

    The biggest problem (IIRC) with Behe's resolution - that God pre-programmed all these structures into the primaeval DNA of the first cells is that through the millions of years they were not required, transcription errors, with no selection pressure because they are not expressed, would have rendered them useless.

    You know what's wrong with IC - your suspicion of God of the Gaps answers is correct. Even if neo-Darwinian theory needs further work (or even some complete overhauling in places - not that I think it does), the answer is not going to be Goddidit.

    Just to add to what Alan and Karl have said (and repeat a bit too):

    When thinking of the evolution of complex structures three key points are these:

    (1) that it is structures and chemicals that are already present that are altered by gradual changes over time to arrive at the structures we have today; and

    (2) that some structures and chemicals that are already present are incorporated into other structures during the course of the evolution of a complex structure or organ;

    (3) as long as each intermediate stage is an advantageous improvement on the previous stage then it does not matter that the intermediate stages are not as good as the final stage.

    When you ask “How does a patch of photosensitive skin transmit data to the brain, unless there's a connection? And if there's a connection, did that develop at the same time as the skin? Don't we come back to the irreducibly complex argument?” you are assuming that the skin had no link with the nervous system when it became photosensitive. You need to ask what was there to begin with before the photosensitivity began. It is likely that the skin in question would have had some nerves in it already, doing other useful things (detecting certain chemicals say). Skin that acquired photosensitivity would thus be connected up already. That patch of skin would thus fire off nerve impulses in different circumstances to the surrounding skin. If the response of the organism to those firings was, as with the chemical detectors ‘move in that direction’ and this was advantageous then it would tend to be selected for. (This is from point (1) above.)

    When you say that “looking at the way the eye does work now, in that all the sub systems must be functioning in order for sight to be possible” you are not quite correct. Ask any partially sighted person, (e.g. a person with no lens in their eye) if they can see and they will say ‘yes’ or ‘yes, but …’. Karl also illustrates this when he lists the wide range of more or less sophisticated types of sight there are. (This is point (3) above – intermediate stages are functional despite not being as sophisticated as the final stage).

    A typical proposal for the stages of the gradual evolution of the mammalian eye goes something like this:

    An organism (well before mammals arose) with a nervous system with nerves in its skin:
    a) has a patch of skin that is photosensitive. This is an advantage if light is correlated with something beneficial or harmful for the organism
    b) that patch is larger. This may be advantageous because it makes the organism more sensitive to light than those of its kind that have a smaller patch.
    c) the patch becomes covered in a protective layer of translucent cells
    d) the patch becomes curved inwards. The nerve messages from concave patch of photosensitive cells will be different to a flat patch because if the light is coming from an angle then one side of the patch may be in shadow while the other is fully lit. The direction of the light source is thus more accurately known. If this is an advantage to the organism it will tend be selected for by natural selection.
    e) with an even more concave patch of cells the effect becomes like a blurry pinhole camera and still more information can be derived from the nerve messages.
    f) the transparent protective layers of cells that now fill the cavity changes its refractive index and thus improves the image on the retina;
    g) a portion of this layer near the hole is particularly critical for this and comes to form a lens;
    h) additional features such as an iris also evolve;
    i) the shape of the cavity also alters to best suit the focal length of the lens;
    k) concurrently with this, the brain of the organism is also evolving and those organisms in the population which develop neural pathways which can get more useful information out of the more accurate images will be selected for.
    l) and also concurrently with this, the variety of pigments in the photosensitive cells can also evolve.

    Key points about this are that:
    - each step is functional;
    - no step requires that a large numbers of adaptations to take place all together for any of them to be a benefit;
    - each step is advantageous compared to the previous one IF increased visual acuity is likely to increase the survival and reproduction of the individual of the species. (As Alan has pointed out, if you are an animal that doesn’t need visual acuity then it is not to your advatage to have great eyes).

    As an illustration of point (2) mentioned earlier, the lens of sophisticated eyes are filled with globular proteins called crystallins. Nowadays we can sequence proteins and, lo and behold, we find that these crystallins are proteins identical to or slightly modified versions of proteins elsewhere in the body that are used for different functions e.g. certain enzymes. So it is not necessary to evolve an entirely new protein from scratch but instead a protein already in use elsewhere gets conscripted in, as it were, for a different function in the eye.

    (For some discussion of these matters see Mark Ridley (ed) Evolution (an Oxford Reader – a collection of articles and extracts from many authors) in particular Dan-E. Nillson and Susanne Pelger ‘A pessimistic estimate of the time required for an eye to evolve’ - their estimate is 363992 generations i.e. much less than half a million years.)

    And there are countless examples of cellular mechanism that depend on multiple protiens in order to work.

    Neo-darwinsim does not work on the molecular level. Hence it cannot be true.

    The three principles that I outlined in my last post apply at the molecular level too.

    (1) that it is structures and chemicals that are already present that are altered by gradual changes over time to arrive at the structures we have today; and

    (2) that some structures and chemicals that are already present are incorporated into other structures during the course of the evolution of a complex structure or organ;

    (3) as long as each intermediate stage is an advantageous improvement on the previous stage then it does not matter that the intermediate stages are not as good as the final stage.

    Your argument assumes that you need at least 9 proteins to make a cell light sensitive, but that is a highly questionable assertion. What grounds do we have to insist upon it? It is not sufficient to point to that number being used now in light sensitive cells, we are interested in much earlier forms of life. Is it not possible that a gradual stepwise progression to this current number and arrangement occured with each stage being functional but less good than the next? I simply fail to see how that can be dismissed even after the kinds of arguments Behe offers. You will find references to Behe's arguments in the earlier parts of this thread. Karls reference to Miller is very much worth following up.

    Here are the comments of Matthew Brauer and Daniel Brumbaugh on Behe's discussion of the visual-pigment signaling cascade.

    quote:
    One would never know from his detailed discussion of the molecular steps in the pathway that they are, in fact, ubiquitous features of many different signalling processes in most cells. ... The proximate step of visual perception is part of the GTP-coupled receptor signaling pathway ... whereby a stimulus from outside the cell can quickly ... change the chemical state of the cell. The phot-receptor apparatus merely modifies one of these steps to acccomdate a photon as the source of the external signal. Other cells modify the same pathway as well. In ova, for example, the GTP-coupled pathway is triggered by the adhesion of a sperm cell. (from 'biology Remystified: The Scientific Claims of the New Creationists' Matthew Brauer and Daniel Brumbaugh (p316) in Intelligent Design Creationism and Its Critics edited by Robert T. Pennock MIT Press (2001))
    In other words an evolutionary explanation of photosensitivity would involve adding a step to or altering a step of an existing signaling system rather than beginning the whole thing from scratch. Precursors to a new complex structure or pathway do not have to have been involved in the same function as the new structure or pathway. The construction of evolutionary explanations of such complex features can thus suggest that not just new single items are added to a system or altered but that existing systems are co-opted into the new set up as well.

    Clearly there must be some complex processes built up single step by single step, but there is no reason to suppose that the irreducible complexity argument applies to all molecular processes. Once some are thus evolved they can contribute to the evolution of qualitatively more complex pathways and structures.

    Chlorophylls (there are a number of sorts) are not proteins but rather complex multiple-ring compounds. But they exist in the chloroplast as part of very complex structures involving proteins, lipids, carbohydrates and other things.

    And they are bloody sophisticated and complex enough already. Metabolically much more complex than anything that goes on in a mere mammalian eye!

    Why is it that those who want to claim Darwinism is impossible always concetrated an the easy examples that are simplest to defeat?

    They go on about bird flight, when we have great explanations for the evolution of bird's wings and feathers. Many of them. The yeccies never ask about the evolution of insect wings, a much more controversial subject.

    And eyes. They love talking about eyes. Which are of all the complex structures in the body just abotu the easiest to imagine the evolution of.

    And perhaps actually to evolve - complex eyes like ours seem to have evolved at least twice and arguable half-a-dozen times.

    But they keep off the really difficult questions in evolution. Such as:


    Can't Behe and his mates attack on the bits of biology that are still obscure?

    Then the effort to refute them might stimulate some genuine new thought instead of just getting people to drag out the same old arguments.

    The octopus' eye doesn't have the "bug" that causes the blind spot in human perception, for example.

    And there's a vestigial bone sometimes found in the human thumb that's either the "lost" phalange or a descendant of a dewclaw-like structure. Little bits of leftover that show that H. sap is not the peak of creation are significant to me.

    Glenn,

    Firstly, thanks for your intelligent and interesting reply. I like the point you made about your degree - not boasting but stating back ground. I hope everyone realises that is my reason. Despite my evangelical background my doubts about Neo-darwinism are all born out of my degree in molecular biology and not theology.

    I also liked the link Karl, liberal back slider gave to the clotting cascade explanation. That was very interesting.

    I have found that many atheists are very dogmatic about evolutionary theory, because their entire world-view depends on a God-less explanation of life, whereas I would claim to be open-minded. I do not think that a literal interpretation of Genesis makes a great deal of sense theologically, let alone scientifically. Thus I am happy to take or leave evolutionary theory.

    One interesting thought though (well I think it's interesting): I stated earlier that I am very nervous of any explanation that tends to a 'God-of-the-gaps' view of science. For one thing it's not biblical. However the idea that science will be able to explain life and diversity of the species is dependent on the assumption that science works - that the universe is rational and predictable. This is only an assumption, nothing more. (Unless of course you believe in a God who made a rational universe).

    Anyway that's enough of that. The key issue is and always will be, can complex biological structures devolop in a stepwise manner? Two key factors are necessary for this. 1. That pre-existing proteins can gain new functions, thus not starting from scratch; 2. Gene duplication.

    My knowledge of proteins is not as strong as my knowledge of genes but the idea of adapting proteins I currently find unconvincing. {I look forward to Glenn's view on this). Secondly I think the prominence of gene duplication is unconvincing, there are not many examples of functioning duplications that I can think of; the globin family is the only one that comes to mind. Although I admit my knowledge is limited on this point.

    Hey, maybe I'm wrong, I'm not a zealot, but real science asks the questions, please try and persuade me. My main conclusion from reading Behe's book was that I agreed with him about the problems of Neo-darwinsim but did not want to jump to the ID conclusion.

    Hundreds discovered so far. Maybe thousands.

    There are the ribsomal RNA genes and tRNA genes, all through life.

    There are bacterial sigma factors involved in DNA transcription.

    There are the homeobox genes.


    This weekend I was reading some papers on the Mycobacterium genomes (bacteria that causes tuberculosis + some relatives) & there are, for example, a large number of duplicate or near-duplicate genes involved in fat metabolism, which can be used to trace relationships between and within the species. Also a whole family of genes called PE/PPE which are apparently new to that bacterium - and seem to derive closely from a known gene family, and have been duplicated many times in the TB organism.


    That's just off the top of my head - I've seen estimates that about 15,000 human genes - almost half - are visibly the product of evolutionary recent duplication (obviously many more than that might be further back)

    Have to say that natural selection is not evolution. Natural selection is an exchange of information (via genes) that results in loss of information. Therefore there would be degeneration not upward progression. The main truth about the theory of evolution is that it is a theory and not fact. Darwin himself was worried about the lack of transitional fossils. He reasoned (correctly) that evolution should produce fossils in transition, half man, half monkey, half fish, half land animal. No such fossils have been found.

    The reason for this is because the bible tells us that God made the species "after their kind" so a dog is a dog, a monkey is a monkey. Evolutionists say we evolved - goo to you! God says He made us. Which is more fantastic, that a Creator God made everything or matter appeared somehow and we kind of made ourselves?

    That's really the choice, I think. Comes down to belief because evolution is nowhere near to being proved.

    Correct. Natural selection is the mechanism by which features advantageous for survival and reproduction in a given environment are persist at the expense of less advantageous features. It is not so much theoretical as blindingly obvious.

    quote:
    Natural selection is an exchange of information (via genes) that results in loss of information.
    Exchange of information in genes is called sexual reproduction. It is a very powerful mechanism for new genetic information to be shared among a population group over several generations (assuming that new information is beneficial, see "natural selection" above). This may result in the loss of genetic sequences from a population that prove to be non-beneficial.

    quote:
    Therefore there would be degeneration not upward progression.
    Only if there was some finite initial set of information. Introduce a mechanism for generation of novel features such as genetic mutation, a means of propogating that information (such as sexual reproduction) and a means of sorting good from bad new information (natural selection) and you can actually generate significant amounts of new information in a relatively short amount of time. So much infact, that mechanisms have evolved to slow the rate of mutation through gene repair mechanisms.

    quote:
    The main truth about the theory of evolution is that it is a theory and not fact.
    Yep. And gravity is just a theory too which doesn't mean you float off into space. Oh, and guess what, the world being created in six days some 6000 years ago is also a theory - it just happens to be a theory lacking anything like the amount of supporting evidence evolution has.

    quote:
    Darwin himself was worried about the lack of transitional fossils. He reasoned (correctly) that evolution should produce fossils in transition, half man, half monkey, half fish, half land animal. No such fossils have been found.
    Darwin worried because the number of fossils known to him was very small, so much that even if transitionals existed in it the lack of earlier and later forms would have made it impossible to identify them. The fossil record we currently have is stuffed full of transitional forms. For example, here is your fish-amphibian transitional, or a series of hominid skulls showing ape to human evolution (sorry the distance from human to monkey is so great the number of transitionals is enormous).

    quote:
    Which is more fantastic, that a Creator God made everything or matter appeared somehow and we kind of made ourselves?
    Well, personally I'm happier with a physical universe that is so well made that it follows a consistant, logical and fairly comprehensible set of regularities that we call natural laws. A universe that is capable of generating novelty and variety through time. A far more impressive a feat for the creator than a static dull universe that never changes significantly. Not to mention the problems of believing and trusting in a creator who, if your position is correct, goes out of his way to deceive us into believing that the universe is significantly different from what any reasonable person may deduce from what we observe.

    quote:

    Yep, belief.

    Irrefutable evidence that the universe is approximately 15 billion years old, with the earth 4.5 billion years old. Irrefutable evidence that life appeared early in the history of the earth, and gradually developed into more complex forms. Or dismiss this irrefutable evidence for some fairy tale based on an over simplistic reading of a few verses in a book. Yep ... I know where my belief is.

    I think you'll find the "examples" are altered, they're what man imagines the missing link to be. Go into any museum and ask to see an original fossil of a "monkey man" and you won't get one. If your theory is correct why are no chimpanzees contributing to this forum?

    Evolutionist's arguments seem to be "Oh God is just a theory but trust me, science is fact." It's not empirical science at all.

    As for finite initial information, that's just what there is. Genes are a code. Proven! Fact! Genetic information contains instructions to produce so human genes produce humans, dogs produce dogs.

    I would like to see the irrefutable evidence that the universe is millions of years old. I can show you studies where living snails have been carbon dated at thousands of years old. Hardly reliable that. There are numerous fossils of upright trees in rock. Impossible over millions of years because the tree would have long since rotted but consistent with a sudden deluge as in Noah's flood.

    And what about the second law of thermodynamics? That's a natural law isn't it? If everything tends towards atrophy how can there be upward development?

    Irreducible complexity? What did we start off as, a big toe? The body is a unit, take away any one of many organs and it doesn't work. I'd like to see a diagram of a human evolving, I really would. I suspect many evolutionists would too.

    OK, try this. You know those bug zappers, blue light and a fly flies into it and zap, he's toast? Mr fly flies into it and his mate says "What happened to fred.... think I'll take a look at this blue light - aaaaah!"

    See, that's a danger but flies haven't adapted to it yet they're still here. They haven't the brain power to adapt, they haven't the genetic code. They're flies, that's all they'll ever be.


    God has deceived no one, rather man chooses to disbelieve what God has said. It's the same evidence for creationist and evolutionist alike, it's the interpretation that is different.

    Population Statistics...World population growth rate in recent times is about 2% per year. Practicable application of growth rate throughout human history would be about half that number. Wars, disease, famine, etc. have wiped out approximately one third of the population on average every 82 years. Starting with eight people, and applying these growth rates since the Flood of Noah's day (about 4500 years ago) would give a total human population at just under six billion people. However, application on an evolutionary time scale runs into major difficulties. Starting with one "couple" just 41,000 years ago would give us a total population of 2 x 1089. The universe does not have space to hold so many bodies.

    I could go on...

    What??? You're claiming that transitional fossils are all faked??? That is one heck of a claim to make!

    Many museums have early hominid fossils on display, though I agree you won't find a "monkey man" - plenty of "ape-men", but no monkeys. Which just goes to prove we're descended from apes not monkeys. If you're in London, or ever visit, try the Natural History Museum.

    There are no chimpanzees here because chimps, though close relatives to humans, are not human. Both species evolved from a common ancestor living several million years ago - an ape ancestor, not a monkey.

    quote:
    As for finite initial information, that's just what there is. Genes are a code. Proven! Fact! Genetic information contains instructions to produce so human genes produce humans, dogs produce dogs.
    Genes code for proteins, proteins form cells, cells form larger organisms. The genes in a human produce many of the same proteins as are found in dogs, and many more very slightly different ones. They also encode protein expression such that we are humans, and they are dogs. Comparisons of DNA show that the genetic code of all species is very similar. Either God got lazy and reused his code book all the time, or we evolved from common ancestors bringing with us those genes. But, at some point in the past (and at present in simpler organisms such as bacteria) genetic codes were much shorter and simpler. As creatures evolved the genetic code was added to and adapted. There are plenty of mechanisms known for genetic information to do this, mostly to do with replication of genes or even entire chromosomes coupled with sexual reproduction to share the new versions through a population.

    quote:
    I would like to see the irrefutable evidence that the universe is millions of years old.
    I bet you would, cos that would prove me wrong. 15 billion years old is the approximate age of the universe. It's derived from studies of galaxies and their relative motion (the universe is expanding from a single point), studies of the cosmic microwave background (afterglow of the Big Bang) and so on. The age of the earth at about 4.5 billion years old is derived from radioisotope dating of old rocks on earth, but mostly from meteorites as the earths surface is relatively young having been reworked by geological processes.

    quote:
    I can show you studies where living snails have been carbon dated at thousands of years old.
    And, if they were living in a marine environment or on limestone then that's what one would expect. It is a well known effect in radiocarbon dating, one that in most circumstances can be corrected for, albeit with a reduced precision on the actual age produced. But, that's irrelevant anyway as radiocarbon dating is unsuitable for materials older than about 50000 years and so isn't used to date anything but the most recent geological events. There are plenty of other radioisotope dating systems that prove beyond doubt the antiquity of the earth and the ages of different fossils found in the earth - starting with very simple bacteria some 3.5 billion years ago and progressing to multi-cellular organisms and then animal life in just the broad picture that evolution predicts. Either that or God has been highly deceptive.

    quote:
    And what about the second law of thermodynamics? That's a natural law isn't it? If everything tends towards atrophy how can there be upward development?
    The Second Law of Thermodynamics applies to closed systems. The universe as a whole is closed, but the earth isn't (we receive energy from the Sun). Local increases in order are perfectly acceptable - indeed any sort of useful work relies on the Second Law. I've I thread in Limbo on this subject, here, that you might be interested in.

    quote:
    God has deceived no one, rather man chooses to disbelieve what God has said. It's the same evidence for creationist and evolutionist alike, it's the interpretation that is different.
    Yes, the evidence is. 1) Very old universe (15 billion years) 2) almost as old earth (4.5 billion years) 3) genetic similarities between all living organisms 4) fossil organisms irrefutably dated to ages in the distant past of (mostly) creatures no longer alive 5) physical similarities between fossils and living organisms strongly suggestive (nice understatement eh?) of common ancestry 6) many fossils of forms that are strongly suggestive of being transitional between other forms, dated to being older than the recent ones and newer than the older ... I could go on.

    That's the evidence. The interpretive choices are 1) God created everything recently with all this evidence of antiquity and evolution, 2) God created everything over a long period of time utilising the very regularity he built into the system or 3) God doesn't exist and everything is just chance. I'd go for 2 everytime, but can recognise the case for 3. Sorry, but 1 is a God I cannot possibly believe in.

    Well I had a look at your pratt board, I must admit, you've no room for another view. You're sticking to your unproven theory and that's that.

    Not everyone is closed however. Here are a few examples fro scientists who do not subscribe to evolution:

    1. The Fossil Record...Evolutionists have constructed the Geologic Column in order to illustrate the supposed progression of "primitive" life forms to "more complex" systems we observe today. Yet, "since only a small percentage of the earth's surface obeys even a portion of the geologic column the claim of their having taken place to form a continuum of rock/life/time over the earth is therefore a fantastic and imaginative contrivance.1" "[T]he lack of transitional series cannot be explained as being due to the scarcity of material. The deficiencies are real, they will never be filled."2 This supposed column is actually saturated with "polystrate fossils" (fossils extending from one geologic layer to another) that tie all the layers to one time-frame. "[T]o the unprejudiced, the fossil record of plants is in favor of special creation." 3
    2. Decay of Earth's Magnetic Field... Dr. Thomas Barnes, Emeritus Professor of Physics at the University of Texas at El Paso, has published the definitive work in this field.4 Scientific observations since 1829 have shown that the earth's magnetic field has been measurably decaying at an exponential rate, demonstrating its half-life to be approximately 1,400 years. In practical application its strength 20,000 years ago would approximate that of a magnetic star. Under those conditions many of the atoms necessary for life processes could not form. These data demonstrate that earth's entire history is young, within a few thousand of years.
    3. The Global Flood... The Biblical record clearly describes a global Flood during Noah's day. Additionally, there are hundreds of Flood traditions handed down through cultures all over the world. 5 M.E. Clark and Henry Voss have demonstrated the scientific validity of such a Flood providing the sedimentary layering we see on every continent. 6 Secular scholars report very rapid sedimentation and periods of great carbonate deposition in earth's sedimentary layers..7 It is now possible to prove the historical reality of the Biblical Flood.8
    4. Population Statistics...World population growth rate in recent times is about 2% per year. Practicable application of growth rate throughout human history would be about half that number. Wars, disease, famine, etc. have wiped out approximately one third of the population on average every 82 years. Starting with eight people, and applying these growth rates since the Flood of Noah's day (about 4500 years ago) would give a total human population at just under six billion people. However, application on an evolutionary time scale runs into major difficulties. Starting with one "couple" just 41,000 years ago would give us a total population of 2 x 1089. 9 The universe does not have space to hold so many bodies.
    5. Radio Halos...Physicist Robert Gentry has reported isolated radio halos of polonuim-214 in crystalline granite. The half-life of this element is 0.000164 seconds! To record the existence of this element in such short time span, the granite must be in crystalline state instantaneously.10 This runs counter to evolutionary estimates of 300 million years for granite to form.
    6. Human Artifacts throughout the Geologic Column...Man-made artifacts - such as the hammer in Cretaceous rock, a human sandal print with trilobite in Cambrian rock, human footprints and a handprint in Cretaceous rock – point to the fact that all the supposed geologic periods actually occurred at the same time in the recent past.11
    7. Helium Content in Earth's Atmosphere... Physicist Melvin Cook, Nobel Prize medalist found that helium-4 enters our atmosphere from solar wind and radioactive decay of uranium. At present rates our atmosphere would accumulate current helium-4 amounts in less than 10,000 years.12
    8. Expansion of Space Fabric...Astronomical estimates of the distance to various galaxies gives conflicting data.13 The Biblical Record refers to the expansion of space by the Creator14. Astrophysicist Russell Humphries demonstrates that such space expansion would dilate time in distant space.15 This could explain a recent creation with great distances to the stars.
    9. Design in Living Systems...A living cell is so awesomely complex that its interdependent components stagger the imagination and defy evolutionary explanations. A minimal cell contains over 60,000 proteins of 100 different configurations.16 The chance of this assemblage occurring by chance is 1 in 10 4,478,296 .17
    10. Design in the Human Brain...The human brain is the most complicated structure in the known universe.18 It contains over 100 billion cells, each with over 50,000 neuron connections to other brain cells.19 This structure receives over 100 million separate signals from the total human body every second. If we learned something new every second of our lives, it would take three million years to exhaust the capacity of the human brain. 20 In addition to conscious thought, people can actually reason, anticipate consequences, and devise plans - all without knowing they are doing so.21

    [a point about posting style]


    Mr Marshall

    If you're just going to cut and paste stuff off the Web, it's easier (and more honest) to just provide a URL to it. Most people on here can, I guess, use Google to find out which Creationist forum you copied it from, and if you neither credit nor link to it those people might suspect you don't really understand what you're talking about. Or you want to be seen as an original thinker when you're just taking other people's ideas. I struggle to think of a more charitable explanation.

    Another exciting side effect of using Google is that you can find comprehensive answers to all those points so painstakingly cut and pasted. If you don't understand those answers, or if you understand them and think they're flawed, then you should say so. Otherwise, everyone will think you're ignoring the answers because... oh, again, various explanations suggest themselves. None complimentary.

    If you want to have a debate, and I see that you claim you do, then you have to follow certain basic rules of honesty and discipline.

    [/point]

    Have you got any substantive objections to any of the PRATT content? Or do you just not like it very much?

    So the idea is to question my honesty rather than answer the questions? If I'm dishonest my ideas can't be trusted? Good enough ploy I suppose. I haven't heard any honest answers to my legitimate questions, only disparaging remarks. Anyway, here's two links:

    http://www.creationevidence.org/
    http://www.answersingenesis.org/

    but you could google loads more.

    I have researched using the web, I see nothing wrong in that. Just because I agree with the content does not make me dishonest. At least I provided references. Perhaps you could point me to definitive texts that prove evolution? Any that I've seen (and I have looked) assume that it is not a theory but fact. Many scientists do not accept it proven and they're still accepted as scientists.

    Those points I've posted (pasted!) are valid contentions. I think anyway.

    Well, I've tried to give honest answers. Though there are times I feel like I'm being ignored at times. Anyway, I'll have a crack at some of your cut and paste points. Using my own words.

    quote:
    1. The Fossil Record...Evolutionists have constructed the Geologic Column in order to illustrate the supposed progression of "primitive" life forms to "more complex" systems we observe today.
    Well, first off the Geological Column was devised by geologists, not evolutionists, as a means of describing certain regularities in the way some fossils appear in strata within rocks in various places. Basically it is a means of cataloguing rocks that is true whether or not one accepts evolution. Much of the early work on describing the rocks under our feet and developing the Geological Column was conducted by geologists who sincerely believed they were cataloguing the effects of a global flood - of course, this was before any means of dating the rocks was possible or evolution explained the distribution of fossils within the rocks.

    The earths magnetic field is no to fluctuate. Infact, measurements of the magnetism trapped in rocks as they solidified along mid-ocean ridges show that the earths magnetic field regularly reverses. Measurements over a period of less than 200 years are hardly conclusive of long term trends, even if those measurements were accurate (I'm not sure how good such measurements were 200 years ago, measuring a small magnetic field even today isn't the easy).

    Which ignores the fact that helium (and, indeed hydrogen) is escapes from the atmosphere as well. In fact, I'd be somewhat surprised He influx from the solar wind was significant, the generation rate from radioactive decay on earth must be significantly greater. The main effect of the solar wind is to strip away the upper atmosphere above the protection given to us by the earths magnetic field. Helium (and hydrogen) being significantly lighter gases than the average of the atmosphere tend to rise to the top of the atmosphere and get stripped off into outer space.

    The human brain is a marvelous thing, which the Lord has given to us. It's a real shame some people decide to reject that God-given ability to reason and the knowledge gained through the application of it.

    Evolution isn't proved. No scientific theory ever is. It is, however, the most consistent explanation for the multitude of facts, the theory with the best predictive power and the one that has been the most thoroughly observed.

    There are many scientists who don't accept the above, true. Few of them work in the field of evolution - and outside a scientist's specialist subject they're not much better qualified than a layman. Most 'scientific' creationists I've experienced are engineers, mathematicians and computer types.

    No, it isn't. There are indeed polystrate fossils connecting layers. There are layers that were formed close in time to each other. There were others that were not. Find a polystrate tree that links an early Jurassic bed to an early Cretaceous one and you've got something.

    quote:
    [T]o the unprejudiced, the fossil record of plants is in favor of special creation." 3
    Ooh! Fruits of selective quote mining. Here's the quote in full:

    "The theory of evolution is not merely the theory of the origin of species, but the only explanation of the fact that organisms can be classified into this hierarchy of natural affinity. Much evidence can be adduced in favour of the theory of evolution - from biology, bio-geography and palaeontology, but I still think that, to the unprejudiced, the fossil record of plants is in favour of special creation. If, however, another explanation could be found for this hierarchy of classification, it would be the knell of the theory of evolution. Can you imagine how an orchid, a duckweed, and a palm have come from the same ancestry, and have we any evidence for this assumption? The evolutionist must be prepared with an answer, but I think that most would break down before an inquisition.

    Textbooks hoodwink. A series of more and more complicated plants is introduced - the alga, the fungus, the bryophyte, and so on, and examples are added eclectically in support of one or another theory - and that is held to be a presentation of evolution. If the world of plants consisted only of these few textbook types of standard botany, the idea of evolution might never have dawned, and the backgrounds of these textbooks are the temperate countries which, at best, are poor places to study world vegetation. The point, of course, is that there are thousands and thousands of living plants, predominantly tropical, which have never entered general botany, yet they are the bricks with which the taxonomist has built his temple of evolution, and where else have we to worship?"

    Not this one again - you've already posted it in your last careless cut'n'paste. Have you tried applying these sorts of numbers to bacteria or rabbits? I would suggest to you that it is most likely that throughout the vast majority of humanity's years its population growth rate has been very low - almost zero, as most species' are most of the time. Since we discovered agriculture, and later technology, we have no longer been in equilibrium and have increased in number. There is no reason to suppose this has always been so.

    You are aware there is considerable doubt whether these halos are really formed by polonium? http://www.talkorigins.org/faqs/po-halos/gentry.html talks about it in detail. Is this really something to consider overturning the whole of conventional geology over?

    Which could be why it took three billion years to evolve. Evolution is a great mechanism for creating design, but it's not fast.

    Well, I didn't comment last night because I didn't understand the comment and it was too late to try to figure it out. There are uncertainties in measuring the distances to distant galaxies, if there weren't then we'd have a much better handle on things like the Hubble Constant and the ultimate fate of the universe.

    However, the data is unambiguous in that the universe is expanding. That is, space itself is expanding rather than just that the galaxies are moving through space. I can see how one might want to say that this is what the Bible means when it talks of the heavens being stretched out by God, though I personally dislike such attempts to force the Bible into making statements that predict modern science as I don't beleive that's what the authors intended.

    It follows that as more distant galaxies are travelling away from us at greater speeds than nearer ones that time dilation effects would occur - it would have an effect on the observed light over and above the simple Doppler effect (red shift). But, since time dilation is a well understood phenomenum I don't see the relevance of this to this discussion.

Although I admit my knowledge is limited on this point.

    Thanks for your reply, alienfromzog.

    A useful book that tackles this kind of problem is Cells, Embryos, and Evolution by John Gerhart and Marc Kirschner (1997) Blackwell Science, Inc. Chapter 5 of that book is entitled ‘Novelty’ and looks at how new proteins and new uses for proteins can arise as a result of evolution. The comparative study of protein sequence and structure and of DNA sequencing have revealed much new information about how proteins may be evolutionarily related to each other.

    The main point that they make is that many proteins are composite in that they can be seen as consisting of linked domains. A domain is an amino acid sequence that is capable of particular interactions with other molecules (and often with other proteins). It is increasingly clear that many different proteins have domains that are also found in other proteins. It thus appears that novel proteins may have evolved from the duplication of DNA sequences coding for such domains and from insertion of such DNA sequences into other genes. This giving rise to new proteins in a way that differs from the point mutation of a single codons for one amino acid.

    They also show how existing proteins may be put to new uses. The chapter discusses a wide range of similarities between different proteins and speculates about their evolutionary relationships.

    For example:

    1) Existing Proteins being used for new functions
    Examination of the proteins that make up the lens of the eyes of animals has been studied extensively and many of them turn out to be the same as, or closely similar to a number of metabolic enzymes such as aldehyde dehydrogenase III etc. Here an existing protein with another function has been put to another use altogether. Other lens crystallins resemble heat shock proteins.

    2) Existing Proteins combining to give new function
    Lactose synthetase (the enzyme that produces lactose in the milk produced by many mammals) turns out to be a combination of two sub units, one is galactosyl transferase and the other is alpha lactalbumin. The latter when linked to galactosyl transferase enhances that enzymes poor ability to synthesise lactose and inhibits its usual function of transferring galactose. Alpha lactalbumin is found only in milk, but its three dimensional structure and sequence suggest that it may have arisen from modification of a type of lysozyme. Lysozymes are present in milk and have an antimicrobial function. The suggestion is, then, that at some stage the a lysozyme proteins structure became such that it could bind with galactosyl transferase and thus initiate lactose production. It could then evolve to become more efficient at stimulating lactose production.

    3) Duplications and insertion of a gene allowing new function – ‘exon shuffling’.
    Certain protease inhibitors are short proteins of about 58 or so amino acids. These sequences bear a marked relation to a group of proteins that function as toxins in snake venom. The suggestion here is that the gene for the protease duplicated thus allowing one of the copies to evolve an altered function while the other gene’s protein maintained the existing function. In addition this gene sequence has been found in other locations [I]within[I] other genes so that the amino acid sequence appears within the larger protein from the enlarged gene. Examples of larger proteins in which it appears are are beta-amyloid; a lipoprotein that inhibits blood coagulation; type IV collagen; and, less surprisingly, inter alpha trypsin inhibitor.

    Another example is the family of proteins which are proteases involved in blood coagulation. These have many domains in common. Plasminogen has 5 kringle domains and a calcium binding domain; tissue type plasminogen activator has a finger domain, EGF domain and 2 kringles; Protein C, factor iX and factor X all have 2 EGFs and a calcium binding domain; prothrombin has a 1 calcium binding and 2 kringles; urokinase has 1 EGF and 1 kringle. This naturally suggests that the proteins concerned may have evolved from the shuffling and duplication of DNA sequences for those domains.

    The discovery that many genes consist of introns and exons greatly enhances the possibility of this type of evolutionary explanation. With exons coding for these kinds of domains of proteins then the ease with which the can be duplicated and moved is enhanced.

    Overall, Gerhart and Kirschner state that:
    quote:
    “similarities between protein sequences have allowed us [the biology community] to construct plausible hypotheses for many evolutionary transitions among proteins. … in many cases we can track a plausible direct path of modification and new employment. … The impression from many such examples of composite proteins is that it is not particularly difficult for the cell to generate new protein functions, if the appropriate selective conditions arise.”
    I think this kind of thinking goes a considerable way towards throwing light on the kinds of ways that evolution at the level of proteins may have happened. There is still, doubtless, much to learn, but the kinds of data emerging are satisfyingly coherent with this kind of approach. Does this address some of your concerns?

    So, the refutations. Again. Being selective because there is so much of this stuff. Alan is politer than me, maybe because he is more of a scientist. I will call a prat a prat.

    Well I can't refute this because it doesn't mean anything.

    "what man imagines the missing link to be"? What do you think a "missing link" is? "monkey man?" But monkeys aren't men and men aren't monkeys. We are apes - which are rather different from monkeys. And in fact monkeys evolved more recently than apes. Why on earth should there be such a thing as a "monkey man"?

    And why would you expect chimps to contribute to this forum? Humans and chimps are descended from a common ancestor. But we are different. Which should I any more expect to see a chimp posting here than I should expect to see a creationist half way up a tree eating fruit with its feet?

    Evolutionist's arguments seem to be "Oh God is just a theory but trust me, science is fact."

    A lie. Plenty of people who believe in God and trust God also accept the ideas of evolution.

    If you start from the idea that there is an inevitable clash between Christianity and science then you have already been deluded.

    The lie of young-earth creationism suits a certain kind of heresy that holds that the material world isn't really real, that we aren't animals, that God does not dirty himself with mere matter, and that Jesus dod not truly come in the flesh

    As for finite initial information, that's just what there is. Genes are a code. Proven! Fact! Genetic information contains instructions to produce so human genes produce humans, dogs produce dogs.

    Yes. So? Nothing to refute here. In fact understanding this is fundamental to understanding how living thingn work. If it were not so we'd be living in a sort of chaotic soup (if at all)

    quote:

    I can show you studies where living snails have been carbon dated at thousands of years old. Hardly reliable that.

    So what? What has carbon dating got to do with it? Carbon dating is utterly irrelevant to dating ancient fossils. That you even bring the subject up just shows that you do not know enough to understand the lies you are parroting. A few thousand years either way is like measuring the distance from New York to Rio and being a few inches out.

    There are numerous fossils of upright trees in rock. Impossible over millions of years because the tree would have long since rotted but consistent with a sudden deluge as in Noah's flood.

    So? There are plenty of sudden deluges, flash floods and mudslides all over the place. Fossils of this sort can be seen forming all over the world. They are rare - but they exist.

    quote:

    And what about the second law of thermodynamics? That's a natural law isn't it? If everything tends towards atrophy how can there be upward development?

    This applies as much - in fact even more - to the growth and development of an individual animal or plant. If entropy (not "atrophy") disproved evolution it would also disprove your own growth, or your education (in which your brain gets more organised), or the building of a city where once there was no city.

    OK, try this. You know those bug zappers, blue light and a fly flies into it and zap, he's toast? Mr fly flies into it and his mate says "What happened to fred.... think I'll take a look at this blue light - aaaaah!"

    See, that's a danger but flies haven't adapted to it yet they're still here. They haven't the brain power to adapt, they haven't the genetic code. They're flies, that's all they'll ever be.

    This shows that you are exactly, precisely, missing the point. That you even bring up the topic shows that you do not know what natural selection is. You are confusing it with adaptation and growth. The brain power of flies is nothing to do with this. In your scenario, sooner or later, either all the flies will be dead - which is very possible, most species that ever lived are extinct - , or else those that survive will be the few that for whatever reason avoid blue light. And that's it. That's all you need.

    No-one claims that bacteria have brain power. Yet bacteria evolve immunity to antibiotics before our very eyes.

    God has deceived no one

    But the liars and cheats and hereticswho mislead God's people with the satanic lie called "Young Earth Creationism" have decieved many.

    The Book of God's Word is not at variance with the Book of God's works. These neo-Gnostics and crypto-Mormons who have infiltrated American churches with their young-earther lies are teaching people that the world is an unreal illusion. That studying the world - science - is a sin and a deception. It is a false hyper-spirituality that only works if you believe in a kind of virtual world, and illusion. That's not the Gospel.

    The world is real. Jesus did come in the flesh. God was born on earth as a man - as an animal - as something with a body that had ancestors, that had evolved, that was subject to the normal processes of biological growth and pain and decay.

    The Gospel is not about some docetic idea of a purely spiritual Jesus, a cosmic conjuring show, a white-robed pretence of humanity with a halo and a deep manly synthesised voice.

    God, somehow, was enclosed in a womb. Was a living thing like a little blob, dependent on his mother's blood and antibodies and hormones and nutrients for life.

    The world is real. It works, it has logic, laws, beauty. It was created by God to be good. It was redeemed and made holy and glorified by God choosing to be incarnate in it. One of the many way we can worship God is by learning more about the world.

    If we start off with a suspicion that God is somehopw lying to us, that its all a trick, that what we see around us is an illusion, a virtual-reality creation, full of fossils that never lived, starlight that never came from a star, apparent retro-viral genes that never came from a virus - then we make out God himself to be a liar.

    Starting with eight people, and applying these growth rates since the Flood of Noah's day (about 4500 years ago) would give a total human population at just under six billion people. However, application on an evolutionary time scale runs into major difficulties. Starting with one "couple" just 41,000 years ago would give us a total population of 2 x 1089. The universe does not have space to hold so many bodies.

    [Killing me]

    That pathetic excuse for an argument applies even more to bacteria which can double their numbers every hour. Twenty minutes some of them. Forget 6,000 years. By your logic a single bacterium could fill up the entire world in 6 days.


    quote:

    1. The Fossil Record...Evolutionists have constructed the Geologic Column in order to illustrate the supposed progression of "primitive" life forms to "more complex" systems we observe today.

    Another lie.

    The "geologic column" was not thought up by "evolutionists". Most of the people who worked it out (who were, incidentally, almost all Christians) did not have any idea of evolution. They looked at the rocks, and they realised that the world was very old.

    The oldest references to the great age of the world being demonstrated by geology that I know of are from John Ray in the 17th century, a Christian minister and spiritual writer who was also a botanist. He believed in thespecial creation of Adam and Eve - but he saw from the rocks that the world was far more ancient than humanity and that many species had become extinct.

    Once this was generally realised then many others worked out the details of the strata.

    quote:
    Dr. Thomas Barnes, Emeritus Professor of Physics at the University of Texas at El Paso, has published the definitive work in this field.4 Scientific observations since 1829 have shown that the earth's magnetic field has been measurably decaying at an exponential rate, demonstrating its half-life to be approximately 1,400 years. In practical application its strength 20,000 years ago would approximate that of a magnetic star. Under those conditions many of the atoms necessary for life processes could not form. These data demonstrate that earth's entire history is young, within a few thousand of years.

    Don't your minders update their lies? No-one who had even a decent high-school scientific education could have written this once in the last 40 years.

    The magnetic field gets stronger and weaker over time, it fluctuates.

    quote:
    The Global Flood... The Biblical record clearly describes a global Flood during Noah's day. Additionally, there are hundreds of Flood traditions handed down through cultures all over the world.

    So what?

    Whatever Noah's flood was it was after the creation of humand and all the other species around on the earth at the time.

    Even if every word of the "flood geology" was true - and it isn't, as has been known since at least the early 19th century when Adam Sedgwick and other honest Christian geologists bothered to look at the evidence instead of just reading books about it and found that most of the featues ascribed to the global Flood are in fact glacial - it has NO BEARING WHATSOEVER on the idea of evolution.


    Design in Living Systems...A living cell is so awesomely complex that its interdependent components stagger the imagination and defy evolutionary explanations. A minimal cell contains over 60,000 proteins of 100 different configurations.16 The chance of this assemblage occurring by chance is 1 in 10 4,478,296 .17
    [/QB][/QUOTE]

    Did you even read this crap before posting it? What "minimal cell"?

    When you find someone who believes that evolution can happen by chance, feel free to tell them that I know of none with as few as "100 different configurations" of protein. Most have tens of thousands. No known fee-living bacterium gets by with much less than a thousand. There are some intracellular parasitic bacteria trhat rely on host proteins for many vital functions - for example Mycobacterium leprae that causes leprosy and is probably an ancient parasite of mammals has very many fewer genes, and therefore fewer proteins, than the apparently closely related Mycobacterium tuberculosis

    Thanks for the references. Though I have them already. And if you think I'm going to accept people like Henry Morris as evidence for anything scientific, I have this bridge to sell you.

    Face it. You have been taken in.

    But that is not what is being proposed. Even if you include all the engineers, mathematicians and computer types, the vast majority of scientists have no time for creationism of any stripe. It's just that of the tiny number of scientists who are creationists, a vanishingly small proportion are biologists.

    I am not quite sure of where you are headed with this Neil. If 'Darwinism' is indeed dead then 'neo-Darwinism' is flourishing and that still has extremely strong continuity with Darwinism, in particular in the ideas of common descent and that natural selection is a key mechanism in evolutionary change.

    To echo Karl: what did you have in mind?

    Most scientists do not have a philosophical or theological training. Some therefore can be blissfully unaware when they make statements that are not scientific, but philosophical, or indeed even theological. The concept of fitness at the heart of Darwinism is a very elusive scientific quality, yet it is an essential part of the theory. Philosophers have certainly written on this subject.

    Richard Dawkins is so notorious for straying into philosophical and even theological territory that there is a paper on the Internet entitled A Critique of Aspects of the Philosophy and Theology of Richard Dawkins. Link to Poole’s original paper. Link to Dawkins’ reply. Link to Poole’s further response.

    I don’t have any Internet links on this, but a good book to read for the non-biological specialist (such as myself) is “Creation and Evolution” by Alan Hayward. He is a physicist writing from an evangelical perspective. However, you will be pleased to hear that he comprehensively demolishes the young earth position – he describes himself as an old earth creationist. He also looks hard at the status of Darwinism and other theories of evolution.

    There is a whole chapter on biologists who reject Darwinism, but who hold an alternative evolutionary viewpoint. In some cases these names are not British or American, hence they are not well known in the English-speaking world. Writers mentioned include Erik Nordenskiöld (Norway), Andrée Tetry, Pierre Gavaudan and Pierre-Paul Grassé (France), C. P. Martin (Canada), W.R. Thompson, J.C. Willis and E.J.H. Corner (Great Britain).

    All these biologists have published full–weight academic texts and/or papers critiquing and in many cases rejecting Darwinism completely in favour of some other evolutionary model. I haven’t read any of their work, so I am taking Hayward on trust here. Hayward also documents some of the devastating critiques of Darwinism undertaken by reputable mathematicians and philosophers.

    Note: Quite independently Hayward agrees with Karl that some people have misrepresented Corner’s views by selective quote mining. He also makes it clear that Corner did accept some form of evolution – but definitely not Darwinism!

    The only scientific discipline where Hayward has been unable to document a reputable writer with serious doubts about Darwinism is Anthropology. In trying to understand why, he comments, “Anthropologists, it appears, have so few facts to go on that they deal mostly in opinions”.

    What Hayward is attempting to document is the circular argument that is going on. Evolutionary ideas predate Darwin, but were not widely accepted at the start of the 19th century. However, after a slow start, evolutionary ideas eventually achieved great respectability on the basis of Darwin’s writings and some later developments (especially the science of genetics). But if Darwinism is questionable or even demonstrably false, where does that leave the broader field of evolutionary ideas?

    Your response here illustrates my point perfectly. Is this thread talking about the content of Darwin’s Origin of Species, or the content of Darwinism as it came to be understood by his successors in the late 19th/early 20th century, or the neo-Darwinism that Glenn Oldham mentions (of which Stephen J. Gould and Richard Dawkins are perhaps the most common household names)?

    Darwin mentions a creator a few times in some editions of his book, and it remains a good question just what Darwin’s own religious beliefs were. From Karl’s description it sounds like the remote and disinterested God of the Deists, not the God of Christian theism. I have heard that references to a creator were edited out of some later edition of the Origin, but I can’t document that at present.

    Later generations have certainly fused Darwin’s work with philosophical naturalism to the extent that they are now virtually inseparable. It is one thing to look for a naturalistic explanation of an observed phenomenon, as all scientists do. It is another thing to declare that a naturalistic explanation is the only explanation there can ever be. Phillip Johnson has ably documented that fusion.

    My understanding of neo-Darwinism (which, as Glenn says, is indeed flourishing) is that the whole panoply of life on this planet emerged on its own through the natural processes of physics and chemistry, via common descent, random mutation and natural selection, without any need to invoke an external creator at any point. Design in particular and metaphysics in general are ruled out-of-order from the start.

    Life on earth is then essentially an accidental by-product of the universe, without supervision, meaning, purpose or destiny. That is how I read some scientists. Before I go any further, are we singing from the same hymn sheet on the meaning of neo-Darwinism?

    Which is fine as far as it goes. It is an accurate description of evolutionary theory from a scientific frame of reference. It is this point that is crucial.

    Scientific theories do not need a God. They therefore say nothing about the relationship between any putative God and the phenomenon under investigation. I do not look for a particular role for God to play from a scientific frame of reference, because I believe that the whole evolutionary process is an outworking of God's creative activity, viewed from a (by definition) narrow scientific perspective. I do not expect a "job" for God in it any more than I expect to find which part of quantum mechanics or hydration of white copper sulphate God does.

    quote:

    Yes, because they're not part of the remit.

    As regards these alternative evolutionary models - do you have any links to basic descriptions of them? Can you give a description of any of them?

    I'm not sure there's much fundamental difference between Darwinism and neo-Darwinism. Neo-Darwinism includes a mechanism for gene coding and mutation that was unknown to Darwin. The basic premises of Darwinism - that variability exists, it is inherited, and natural selection operates to selct for beneficial variants.

    It is not an elusive scientific quality, it is a very precise scientific quantity. A simple ratio between countable numbers. The word "fitness" is a bad choice of word for it. (I don't know whether to blame Darwin or Galton for that)

    From memory this is the fitness circle:

    Organism X is exposed to Y pressure. Phenotype A is best suited to the pressure so Genotype B survives and is replicated throughout the population of organism X.

    A is therefore the most fit to condition Y. How do we know? - because genotype B survived. Why did phenotype A survive? - because B was best fit.

    Sorry that is a crap explanation - basically it is very difficult to see externally why one phenotype is better fitted to a pressure than another other than to measure the genotype in a later population of the organism.

    This is a lack-of-knowledge issue rather than a point for or against Darwinism IMO. Something can be true or false independent of our understanding of said phenomena.

    OK, now this is a little more toothsome

    But first a little historical background. There was certainly evolutionary speculation befgore Darwin & Wallace - after all Darwin's own grandfather had written about it. What they managed to do was convince effectively all scientists (& indeed non-scientists who were paying attention) that evolution had occured.

    But from the 1880s to the 1930s something rather odd happened. Although people continued to believe in evolution, Darwinism and natural selection went out of favour.

    There were two main reasons for this: first a lack of understanding of the methods if inheritance - which actually got worse after Mendel's ideas were popularised - some very clever people failed to understand their implications. (you can still read about bollocks ideas like "mutation load") And maybe also that scientists paid too much attention to philosophers, many of whom were stuck in what Ernst Mayr calls "essentialist" thinking, which predisposes them to miss the point of natural selection entirely. The worst offenders were some of the absurd German nature-philoshphers. I wish I could say they were all proto-Nazis like the vile Hackel but in fact the thoroughly sound & decent Virchow was misled too. Though Weissman (about whose politics and personal life I know nothing) always stuck to Darwinism. But all too many of his contemporaries got sidetracked into vitalist nonsense.

    It was only in the early 20th century that geneticists, naturalists, mathematicians, and paleontologists got together to make the "neo-Darwinian" synthesis. One of the sad effects of this is that much writing on evolution from people educated between about 1880 and 1920 (& in Germany and perhaps France from about 1860 to 1940) is simple rubbish [Frown]

    Old Earth Creationism is a different kettle of fish altogether. Historically it was the position of most evangelicals and fundamentalists in the 19th and early 20th centuries. And although it is not in any obvious sense a "scientific" theory (or set of theories) it is at least compatible with the evidence of our eyes. It at least could be true, wheras YEC could not be true (outside the Omphalos). One can respect an Old-Earther.

    Hmm - I haven't heard of most of these blokes.

    Quick web-search....

    Nordenskiold is too early to be very relevant here - he simply lived in the wrong time to have assimilated the ideas the creationists quote him against properly.

    Tetry and Gauvadan I know nothing about. I have only read those few paragraphs by Hayward on them, which, if he reports their views accuratly lead me to think that Tetry actually really is a Darwinist, but is arguing against some straw-man idea of a philosophical "Darwinism" which isn't really relevant to this debate. Our scientific stereotype of the French educational system is that they always tend to over-philosophise. Darwinsism is not a "myth", not a philosophical explanation of the world. It part of Natural History, not Natural Philosophy, still less Ontology or Metaphysics. If Hayward reports Gauvadan accuratly, then Gauvadan is talking bollocks. Sorry, but this looks like the worst of 19th-century German metaphysical speculation about the onward and upward thrust of the life-force. It belongs in the waste bin with all the rest of the Gnostic nonsense. If, that is, he is reported correctly here - I've never heard of him before, never mind read him.

    Similarly the quotes attributed to Grasse by Hayward seem to miss the point. Like so many people he has no idea of the scale involved.

    Willis and Corner are, frankly, evolutionists & to some extent Darwinists - even if they point out loads of problems - but also still stuck in that odd early-20th century so-called "Mendelianism" that was popular before RA Fisher - and since Fisher by people who don't understand him.

    Nope. Neo-Darwinism is just the old Darwinism done by people who understood statistics, population genetics, and phylogeny. It's a "synthesis" because geneticists and ecologists, who had tended to be barking up different trees for a generation or two, were now co-operating.

    It is all about the origin of species, literally. Not the origin of life. It addresses the fundamental question of ecology: "why are there so many kinds of living things?". Not the meaning of life the universe and everything. It leaves that to philosophers & theologians.

    The originators of neo-Darwinism are really RA Fisher, JBS Haldane & Sewall Wright. Backed up later by Julian Huxley, GG Simpson, and Ernst Mayr (who is sort of the historian of the movement - and still alive & still writing AFAIK). Also later people like like David Lack, Willi Hennig, Maynard Smith, RH MacArthur, Motoo Kimura, James Valentine, EO Wilson, SJ Gould, Robert May & so on.

    The arguments of a few decades ago between punctuated equilibrium and gradualism, between neutral evolution and adaptationism, between group selection and individual selection, and between cladistics and doing phylogeny badly, are all arguments within the neo-Darwinist synthesis.

    basically it is very difficult to see externally why one phenotype is better fitted to a pressure than another other than to measure the genotype in a later population of the organism.

    Yes, exactly. This is Natural History, not Natural Philosophy.

    Your fitness is how many grandchildren you have. People with more grandchildren have more grandchildren then people with fewer.

    Really that's all there is to it. Making it into a mythical or philosophical or metaphysical explanation is irrelevant. It'll still be true whatever the philosophers say.

    It is not an elusive scientific quality, it is a very precise scientific quantity. A simple ratio between countable numbers. The word "fitness" is a bad choice of word for it. (I don't know whether to blame Darwin or Galton for that)
    Fitness is a horribly bad word. An organism survives to breed, therefore it is "fit" to survive. There is no measure of fitness other than reproductive success. (Not mere survival.)

    Fitness can mean large size, or small size, large litters or small, hairy or naked, large-beak or small-beak, fast runner or good camoflage. Whatever gets you to breeding more than the other guy.

    Hence, Dawkin's Selfish Gene - the gene survives because it is part of an organism that reproduces. Dawkins does an admirable job of dispelling "group selection" and a number of other dubious bugbears evolutionary theory. The chapters where selection meets game theory are particularly interesting.

    One of the most annoying things is when people start applying some value to "fitness" that is other than the selective one. This rapidly leads to the notion of evolution as have a "destination", and a number of other pathologies.

    Evolution is a strategy for trying everything and keeping what works. If an organism survives by sheer luck - it survives, it is fit, it reproduces. If it is part of a big enough population, its descendants will be a large clade.

    If the planet gets pasturized by a large asteroid and all the dinosaurs die, whatever survives by any means is likely to be the ancestor of the next dominant population. (Although there are more insects than mammals, I think the mammals can claim dominance.)

    Which is fine as far as it goes. It is an accurate description of evolutionary theory from a scientific frame of reference. It is this point that is crucial.

    Scientific theories do not need a God. They therefore say nothing about the relationship between any putative God and the phenomenon under investigation. I do not look for a particular role for God to play from a scientific frame of reference, because I believe that the whole evolutionary process is an outworking of God's creative activity, viewed from a (by definition) narrow scientific perspective. I do not expect a "job" for God in it any more than I expect to find which part of quantum mechanics or hydration of white copper sulphate God does.

    I think you’re being very optimistic here on the willingness of some influential parts of the scientific community to acknowledge that there are other frames of reference apart from the scientific one. It is well documented that some scientists argue that there are no other frames of reference having any truthful reality.

    It is one thing to look for a naturalistic scientific explanation following the known laws of science. Having found such a putative explanation, it is then an easy extrapolation to say that the naturalistic explanation makes any other explanation unnecessary (including a theistic one). From there it is but a short step to say dogmatically that the scientific explanation is the only one that has reality.

    I would argue that any theory based on random, undetermined, and unspecified mutations is in danger of being interpreted in that fashion. There are certainly numerous Darwinists who have made that interpretation, and who have used the weight of scientific credentials to gain a hearing for their metaphysical views.

    The reason for the growth of the Intelligent Design Movement is not just the embarrassing antics of the young earth brigade. Intelligent Design has demonstrated the flimsy intellectual foundations of many Darwinist pretensions, whilst simultaneously documenting the strong political hold that the Darwinists exercise, especially in North America. This is well documented at the Access Research Network site.

    Nordenskiold is too early to be very relevant here - he simply lived in the wrong time to have assimilated the ideas the creationists quote him against properly.

    Tetry and Gavaudan I know nothing about. <big snip> If, that is, he is reported correctly here - I've never heard of him before, never mind read him.

    Hayward’s book quotes Nordenskiöld for a historical and cultural perspective in the early part of the 20th century.

    My edition of Hayward’s book comes from 1985. Most of the research he references was published in the 1960’s and 70’s. He specifically makes the point that some outstanding continental science writers have written against Darwinism, but that they are not well known in the English speaking world, even though their writings are now available in an English translation.

    For example, Pierre-Paul Grassé was a former president of the French Académie des Sciences, whose book Evolution of Living Organisms appeared in French in 1973 and in English in 1977. I haven’t read his work and it is probably far too technical for me to follow, but he certainly sounds a heavyweight in his field.

    Hayward describes Grassé’s evolutionary model as based on “internal factors that compel life to evolve along predetermined lines”. These factors are neither mystical nor magical, and should be discoverable to science. Hayward describes Grassé’s replacement explanation as “vague and unconvincing”.

    Hayward acknowledges that Willis is an evolutionist, but from his description Willis is by no means a Darwinist as far as the plant world is concerned. His evolutionary model progresses in great leaps. At the back of it Willis sees some scientific law yet to be discovered.

    Would that it did! I think any theory that presumes human life to have originated spontaneously and developed naturally through the same route as the animal life around us is going to attract a lot of attention to itself. It is quite clearly the case that for some people Darwinism is indeed the answer to the meaning of life, the universe and everything.

    quote:
    ken said:

    The scientific angle is surely to understand why one genetic configuration has more grandchildren than other genetic configurations. Counting relative survival numbers is not a scientific explanation for why they have survived. Hayward summarises Willis’s opinion on plants as “survival of the luckiest”.

    Well, I've come across scientists who take just that view, scientists who don't believe in God but who subscribe to something like Gould's theory of Non-overlapping magisteria or Popper's demarcation between science and metaphysics and scientists who are theists of one kind or another.
    I don't think that demonstrates more than that scientists, like non-scientists have a range of religious and philosophical viewpoints.

    But equally it is one thing to be awed by the beauty and wonder of the cosmos and another to postulate a creator. Neither position is self-evidently absurd but both positions involve a shift from the realm of science to the realms of metaphysics or faith.

    Surely those scientists are strengthened rather than weakened when Christians advance 'scientific' theories which are patently motivated by a desire to defend the faith. If Richard Dawkins says that evolution demonstrates that God does not exist and Philip Johnson argues that we must all adopt Intelligent Design forthwith because Darwinism is subversive of Christianity then the man on the Clapham Omnibus is going to decide that Darwinism and Christianity are incompatible because both sides agree that is the case.

    The case against Dawkins hinges on the point where he illegitmately shifts his ground from scientific arguments to the realm of metaphysics. When he argues, as he does in the Blind Watchmaker, that God cannot exist because he must have evolved by natural selection it is legitimate to point out that the God of the Christian tradition is an entirely different entity to any that could concievably have evolved in that way. What then ensues is a debate as to whether such an entity exists. If one retorts instead, that natural selection did not happen or did not happen to the extent that Darwinists claim, then Dawkins is quite justified in retorting: "Ah, but it did!".

    I think that Intelligent Design and Creationism are both untrue. But I also think that Creationism and Intelligent Design are staggeringly bad moves tactically because they effectively argue that the mainstream of scientific thought is inimical and deadly to Christianity.

    Part of the whole problem in this debate is the inadequate definition of what is meant by “evolution”, or the specific version of it understood by “Darwinism”.


    I dunno. I don't use Darwinist much - Darwin's ideas are 150 years old and he had but the smallest fraction of evidence we have in the field of biological evolution. Evolution itself is a simple concept: the change in the genetic characteristics of a population over time. Darwin died long before genetics was conceived.

    quote:


    Although the Darwinists do not like to admit it, there are biological scientists who enthusiastically accept some form of evolution, but who have partially or wholly refuted Darwin’s specific ideas. Some have even proposed their own models of evolution, but these lie buried in academic papers and texts, far from the popular mind.


    Such as? Which of Darwin's 'specific ideas' do they refute? How about the subsequent 150 years of scientific thought on the subject?

    'Darwinism', as I think you understand it (as *far* as I think you understand it) has nothing to say about purpose. What Darwin sought to explain was what he observed: how it came to be that way is something else again.

    I don't think you are adequately representing the current state of evolutionary understanding. Until you can correctly identify what's actually going on, I don't think you've got much chance of framing a coherent critique.

    This is philosophy, not science. Unless you're prepared to embark on a discusion of what 'truthful reality' is -- and one dead horse at a time is my limit -- you should accept that science works in the frame of reference which it claims for itself, that of a testable, objective reality conforming to repeatable, observable laws. There may be others, but you won't find science dealing with them. If you want to say scientific ideas of evolution are wrong because they don't explain things in science's own terms, then you have a scientific argument on your hands. If you say science is wrong because it does not involve God, then fine - but unless you can show how this makes for bad science, it's not a scientific argument.

    It's certainly the only one you need to worry about from a scientific viewpoint. Where creation scientists screw up is in saying that their objections to science are themselves scientific.

    Explanations do not *have* reality. They are *about* reality. There is a difference, and science is always concerned with finding the explanation that seems closest to the business in hand. Creation scientists do not play this game: ipso facto they are not scientists.

    Lots of people use a lot of things to form metaphysical views. It does not reflect on the scientific accuracy of those things. Who do you know who accounts the metaphysical views of scientists (who are as prone to dodgy spiritual metafarts as anyone) of more weight because they are scientists - as opposed to plumbers, or TV presenters, or merely charismatic (with a small C) people who have the gift of persuasion?

    Simply not true. ID has singularly failed to demonstrate *anything* beyond wishful thinking. It has no legitimacy among mainstream scientists, and no constituency outside certain categories of religious believers. Most people who support it cannot describe its scientific rationale, let alone defend it.

    Rex, many of your comments have been discussed further up the thread. I would also remind you that I do not subscribe to young earth creation science. Please take your patronising stereotypes elsewhere.

    Your comment about purpose in Darwinism is begging the question. There are many (especially in America, it seems) who say that the scientific theory explicitly excludes any sense of purpose in the Universe. Mutations occur randomly and those that are beneficial are selected passively through environmental pressure alone.

    So Darwinism can certainly be interpreted to be consistent with philosophical naturalism, a most reassuring conclusion for atheists, but troubling for believers. The key question is whether that is an essential philosophical corollary to the scientific theory, or whether such naturalism is an import being read in illegitimately – eisegesis rather than exegesis.

    There is no doubt that the perceived linkage between scientific Darwinism and philosophical naturalism has been the driving force behind much of the writing emanating from the Intelligent Design fraternity. They expect to find purpose in nature and to describe it scientifically when they do so. They are quite open about their metaphysical presuppositions. Would that the Darwinists were equally open.

    As you are sufficiently well versed in what mainstream science says about this matter to critique it, you will no doubt know that the way in which mutations occur and become speciation events is a matter for no little debate. Are you quoting a deliberately simplistic version for dramatic effect?

    Most believers I know are untroubled by this, and given that the atheists I know have never ever said that evolution is evidence for a lack of a god I don't know what reassurance you think they get. I'm sure that some on both sides do think as you state, but surely it's extremely patronising to cast it as a universal truth.

    That key question is badly formed. Perhaps a better question is whether evolutionary biology and theology in general have any link of more import than, say, solid state physics and theology. There are *some* theologies that are grossly insulted by evolutionary biology, but then there are some theologies that are grossly insulted by almost any fact you care to unearth. The Apostolic Catholics believed that the End Times would come about before the last of their appointed elders would die. The gross fact that the last of their apostles died before the End Times kicked off was such an insult to their theology that it did not survive.

    Inasmuch as theology in general is the study of God, then it is best served through science by the dispassionate study of nature to the best of our abilities.

    What matters in science is results. Metaphysics don't enter into it. Why bring them up? The philosophy inherent in the scientific method is statement enough. It doesn't need endless repetition.

    Much though I hate to correct my dear betrothed, I think you'll find that they were the Catholic Apostolic Church and that in fact their theology survived the passing of the last apostle in 1901 by quite some time - their sacramental ministry didn't cease until their last priest died in 1971.

    However that doesn't affect your underlying point as sure enough when the last priest died that reality did, more or less, do for them - although I'm sure there are still a tiny handful of Catholic Apostolic believers around. (There was also a German branch of the denomination which decided to appoint some more Apostles and they are still going - but I digress)

    It is no accident that I have similar thinking to my namesake on the earlier part of this thread (Neil Robbie) – we are both civil engineers by training. As a non-biological specialist some of the debate is technically way over my head. However, the concept of an engineered system is immediately familiar.

    The idea of biological machines has especially appealed to me, particularly the notion of irreducible complexity. I am also no stranger to the concept of design as a science – I even had lectures on the subject at university. So the Intelligent Design fraternity is speaking a scientific language that finds a ready resonance with me.

    Scientific reconstruction of the past is a very different kettle of fish compared to scientific understanding of the present. The scientific aim to discover a testable, objective reality conforming to repeatable, observable laws is fine for the present, but it becomes problematic for the past, and much more difficult for the far distant past.

    By definition the past is neither repeatable nor observable, so we must reply on observation and deduction from the present using whatever clues are available. The present we can observe; the past we must reconstruct. Already we have lost much of the precision associated with science, not to mention the ability to run repeatable experiments.

    Earlier on this thread Alan Cresswell linked to some interesting hominid skull fossils. These are the raw scientific data, clearly representing ancient life-forms of some kind. However, when it is declared that these fossils show the ape-to-human evolutionary transformation, we are in a questionable area of interpretation.

    How do you know that each skull is a remote biological descendant of the earlier one, and that we - modern humans - are remote descendants of any particular fossil? Is it possible to do any form of DNA testing on fossils? Were they even all located in the same geographical area? There is already an assumption operating, and the raw fossil evidence is interpreted within a Darwinian framework.

    I am aware that “natural selection” is responsible for moths getting darker, finch beaks getting longer, and bacteria acquiring resistance. Has anybody demonstrated that “natural selection” has the creative power to make the massive physiological changes necessary in the particles-to-people theory?

    I have read the (highly technical) paper on Observed Instances of Speciation at the Talk Origins website. So far I see pansies remaining pansies, and fruit flies remaining fruit flies, albeit losing the ability to interbreed.

    Given the dogmatism emanating from parts of that site, I would expect to see much better examples of speciation. It simply won’t do to point to small observable changes and say that they clearly demonstrate the validity of the whole Darwinian story. There is a massive piece of extrapolation taking place here on the basis of very limited data.

    Darwinism was described by the French botanist Gavaudan as an “ingenious romance” (quoted in Hayward’s book). I think I agree.

    Yes, the fossils are raw data. But, the challenge is to find some explanation for that data - sticking them in a museum for people to admire uninterpreted isn't science. Now, the data we have in regard to these fossils is (broadly speaking for brevity) that we have a number of fossilised skulls showing different features. Each skull has an associated age and location where it was found. The earliest skulls were all found in approximately the same area in Africa.

    So, what options do we have?

    Well, we can start with the classic Creationist position that God created all things according to their immutable 'kind', and what we have are a collection of different varients on human much as we have different varients of dogs that are still the same species. Now, we have to ask the question "what happened to all the other varients?" as they clearly are not currently in existance? And, related to that, why were only a small number of those varients fossilised at any one time - if all those varients existed at the same time, why was fossilisation so distinctly non-random? The obvious answer is that not all varients lived at the same time, that some appeared later in time after others had died out just as many species of dog had not yet been bred a thousand years ago, and many breeds from a thousand years ago are now very rare if not extinct. This leaves very big questions of why that would be.

    Alternatively we can say that there was a progression of changes in features over time, with (for example) a tend towards larger brain capacity. Now "progression of changes in features over time" is evolution. This is a fact derived from the fossils that is pretty damn close to being as basic as the existance of the fossils themselves.

    Of course, you then move on to a discussion of how that evolution occured and what powered it. I see two basic camps. 1) Each species was specifically created by God to live in a particular environment or 2) Each species is an adaptation on earlier species in response to changing environments. Darwinism and neo-Darwinism are basically the second option.

    How do you know that each skull is a remote biological descendant of the earlier one, and that we - modern humans - are remote descendants of any particular fossil? Is it possible to do any form of DNA testing on fossils? Were they even all located in the same geographical area? There is already an assumption operating, and the raw fossil evidence is interpreted within a Darwinian framework.

    I am aware that “natural selection” is responsible for moths getting darker, finch beaks getting longer, and bacteria acquiring resistance. Has anybody demonstrated that “natural selection” has the creative power to make the massive physiological changes necessary in the particles-to-people theory?

    I have read the (highly technical) paper on Observed Instances of Speciation at the Talk Origins website. So far I see pansies remaining pansies, and fruit flies remaining fruit flies, albeit losing the ability to interbreed.

    Given the dogmatism emanating from parts of that site, I would expect to see much better examples of speciation. It simply won’t do to point to small observable changes and say that they clearly demonstrate the validity of the whole Darwinian story. There is a massive piece of extrapolation taking place here on the basis of very limited data.

    Darwinism was described by the French botanist Gavaudan as an “ingenious romance” (quoted in Hayward’s book). I think I agree.

    I am rather baffled by your post, Neil, you cite several observations all of which are consistent with evolution and then you describe evolution as an “ingenious romance”. Where was the argument supposed to be in this?

    Speciation happens. No evolutionist expects to live long enough to see genera evolve, though if he or she did there would doubtless be creationists still around to say ‘ah yes but they are all really the same kind’.

    The fact that we have no present day observations that can show new genera, families, orders forming does not mean that there is no evidence for common ancestry. The case for evolution is a cumulative one, not one that consists of a single knockout argument. So, to pull in another strand of evidence, why are there so many similarities between species that only really make sense if they have common descent? Why do all mammals have seven neck vertebrae (whales and giraffes alike) and why do all vertebrates have such similar limb structure (the pentadactyl limb)? Why does the giraffe’s laryngeal nerve take a route down from the brain to near the heart and then up to the larynx? That nerve always takes that route in all vertebrates but in the giraffe it means the nerve is 5 metres longer than it needs to be to get from the brain to the larynx. There are no design reasons for all these kinds of similarity, but since the theory of evolution argues that adaptations build on what is already there then these kinds of similarity make sense.

    Why are the chromosomes of chimps and humans so similar, why are their DNA sequences so similar and why are the amino acid sequences of their proteins so similar? They do not need to be. There is no clear reason whatsoever why the haemoglobin of chimps needs to be as similar as it is to the haemoglobin of humans. There are a wide range of amino acid sequences for haemoglobins - why do chimp sequences match humans more than lions? Or sloths? Or goats? There are no known design reasons for these similarities. Once again, however, the theory of common descent explains these similarities and a host of comparable ones in all sorts of species.

    Christians are, surely, familiar with cumulative case arguments – they use them to argue for the truth of Christianity.

    It is no accident that I have similar thinking to my namesake on the earlier part of this thread (Neil Robbie) – we are both civil engineers by training. As a non-biological specialist some of the debate is technically way over my head. However, the concept of an engineered system is immediately familiar.

    The case against Dawkins hinges on the point where he illegitimately shifts his ground from scientific arguments to the realm of metaphysics. When he argues, as he does in the Blind Watchmaker, that God cannot exist because he must have evolved by natural selection it is legitimate to point out that the God of the Christian tradition is an entirely different entity to any that could conceivably have evolved in that way. What then ensues is a debate as to whether such an entity exists. If one retorts instead, that natural selection did not happen or did not happen to the extent that Darwinists claim, then Dawkins is quite justified in retorting: "Ah, but it did!".

    Scientific reconstruction of the past is a very different kettle of fish compared to scientific understanding of the present. The scientific aim to discover a testable, objective reality conforming to repeatable, observable laws is fine for the present, but it becomes problematic for the past, and much more difficult for the far distant past.

    By definition the past is neither repeatable nor observable, so we must reply on observation and deduction from the present using whatever clues are available. The present we can observe; the past we must reconstruct. Already we have lost much of the precision associated with science, not to mention the ability to run repeatable experiments.


    Sadly, that's not true. Astronomers spend all their time observing the past directly (let's ignore the fact that technically so we all do). Fortunately, the things astronomers observe directly touch on the basic mechanisms and laws of physics - so we can immediately tell that in the past, things behaved as they do now, at least on various interesting and useful physical levels. So, whatever mechanisms created the stuff we find around us are the selfsame mechanisms we can touch and experiment on right now.

    The past is accessible and analysable, predictions about what we can find out can be made and tested. Good thing, really, otherwise courts couldn't operate and historians, geologists and oil companies would have a thin time of it.

    I think you misunderstand. Indeed, it isn't generally possible to say that we are descendents of any particular fossil - you may be aware of the continued discussion about whether we are or are not in some way descended from Neanderthal Man. Furthermore, evolutionary theory doesn't say that this should be generally proveable nor that it matters that much (although it's obviously of great interest to find one's family).

    What you can say from the collection of fossil hominid skulls is that there has been a set of features evolving over time, and that we share some of those features. Whether a particular skull is an ancestor of Homo Sapiens or whether it shares a common ancestor with us, is frequently very hard to tell - although one of these two is true.

    What we have is a consistent pattern of changes in structure over time, which is very strong proof indeed in favour of evolution. To deny it, you must either show that the skulls don't show the features or that the proposed sequence is incorrect. True, there is an element of tautology here, in that evolution is so widely assumed that the change in features are used to help create the sequence, but that's merely because there is so much evidence from elsewhere that this is a correct approach. Some of the sequencing from microscopic prehistoric sea creatures is staggeringly detailed and complete over very long stretches of time, because here we have such good and complete fossil records - find me a creationist micropaleontologist, and I will be truly impressed.

    There are other dating methods used, and they bolster this approach -- were they not to do so, then it would be an interesting start to proving evolution false.

    The whole world demonstrates this! The question is rather, is there any demonstrable (or even conceivable) limitation on variability that would prevent such changes? What might be the limiting mechanism? Is a lungfish enough like a fish to be a possible modification? Is an amphibian enough like a lungfish to be a possible modification? Is a lizard like an amphiban, ditto? So why can a lizard not be descended from a fish?

    Creationists are fond of quoting 'goo to you' as an example of how evolution cannot possibly work because the change is just too big. But that's not how evolution is thought to work - many small changes over time will do it. You may never find a pound on the pavement, but pick up enough pennies...

    But no! There are enormous amounts of data. You've already said that sufficient levels of mutation occur even in the short term to cause population divergeance to the point where interbreeding cannot occur. We see this in the fossil record too. However, the fossil record does what our quotidian observations cannot, it extends over much larger stretches of time. We see sequences of species diverging and becoming very different -- once they cannot interbreed, this is what you'd expect over time -- and this happens consistently and in agreement with multiple independent methods of dating.

    In fact, if we did observe gross speciation events occuring 'in real time', which is what you seem to be complaining is missing, then it would be strong evidence that our concepts of evolution are badly flawed. Frogs don't turn into dogs: evolution merely says that at some very distant point in the past, frogs and dogs had a common ancestor.

    I agree too, up to a point - a lot of evolutionary science is ingenious romance. A criticism frequently levelled at evolutionary biologists is that they spend their time writing Just So stories. Which they do, but to see this as a weakness in evolution is to fundamentally misunderstand it.

    The truth is that, just like any science, various theories are advanced that seem to fit the facts and people spend their time inventing these ideas and digging out ways to test them. Evolutionary biology defines the sort of Just So stories that can be written and sets the limits of the plausible. Evolution itself is as well proven a scientific fact as any we have: the details and the implications are what the science is all about.

    Creation science falls well outside the plausible space. There is simply no scientific evidence for it, and predictions that would seem logical -- such as huge numbers of very different animals appearing simultaneously in the fossil record -- are so clearly at odds to what we find that no creation scientist can make them.

    Sorry, first an evolutionist cannot appeal to concepts of features that could be constructed sequentially over time - but at the same tell engineers to mind-their-own-business when told it cannot physically be done. I would think engineers are at least as well qualified as biologists to make this assessment.

    Second, you are now falling into the Dawkins this-happened-because-I-said-it-did trap. Let us wake up and smell the coffee here. How many huminoid fossils are there in existance? Answer - not many, of the oldest at least. What circumstances would encourage fossilisation? I would postulate that people with mental illness, sickness or other infirmity are more likely to find themselves in situations suitable for fossilisation than fully fit members of the community. Morein, I would not be surprised if the huminoid 'adaptions' found in the fossils are also found within the normal variation of the species (think of the 'elephant' man for example - would he not have been considered another species if his fossil had been found in isolation?).

    I suggest to you that there is, therefore, at least the potential for major errors to exist within human evolution.

    Prehistoric sea creatures are not relevant to questions of human evolution. Trilobites, for example, were around from the cambrian with relatively minor variations for millions of years. What does this show? If you look for evidence [both within the fossil record and in nature as a whole] you will inevitably find whatever you are looking for. This is not to say that evolutionary theory is wrong just that some of you guys need to be a whole lot more circumspect and less defensive about it.

    And before any creationist thinks of pming me, read my previous comments.

    Nobody, biologist or engineer, is qualified to make that assessment unless they can follow it up with a 'because...' that stands scrutiny.

    Behe says that there are biological systems that could not have evolved because there is no way they could exist in a part-functioning or incomplete state - and thus nothing they could have evolved from. They are irreducably complex, in his term, because they have multiple necessary components, removal of any one of which causes the system to cease to function.

    Unfortunately for him, the mechanisms he's chosen to exemplify this theory have plausible evolutionary pathways - evolution can indeed produce 'irreducably complex' systems. All that's necessary is a system that was merely beneficial in the past becoming essential through modification. Further beneficial mechanisms can then come about that depend on the first one, and if one of those new beneficial mechanisms also becomes essential you have two essential connected components that nonetheless evolved independently and at different times.

    Well, these are all possibilities - but in the absence of statistically significant numbers of fossils, you have to apply what we know of probability. In a population of hominids, how many mutants are there? How many survive any length of time? Compare that to the number of typical examples: in Victorian England, there was one Joseph Merrick for how many millions of more typical homo sapiens?

    Also, the features of the hominid skulls seem to fit a number of patterns of development - jaw structures, occipital bones, even the structure of the brain as revealed by the inside of the skulls. It's not as if there are so many random features that are shuffled around by the evolutionary biologists to make a pleasing picture.

    quote:

    Absolutely. It just doesn't seem very likely on the evidence we have, and nobody's come up with a better explanation that fits.

    You can find very many different strands of evolution, including families of animals that remain substantially unchanged for many millions of years, and including quite dramatic changes in much smaller periods. It's not a question of 'finding whatever you're looking for' - something which is patently false, as there's nothing there that supports creationism - but having a huge encylopedia of past events that may help inform our understanding of biology as a whole.

    Everything is connected, everything is useful: the one rule is that there won't be anything in the fossil record that contradicts something else. If that apparently happens, we know that our understanding is wrong.

    A “false friend” is an incorrect deduction from prior knowledge of one language concerning a similar-looking word in a text of another language. In such a case there is a prior assumption that the text is meaningful. However, the specific deduction on the word’s meaning is incorrect.

    The error is in the detail, not in the overall principle. The text is meaningful, but not in the way that you thought. Simon and Garfunkel said it all 30 years ago, “A man sees what he wants to see, and disregards the rest”.

    Concerning biological machines, the same laws of physics and chemistry apply to both biologists and engineers, in a way that they do not to linguists. Deductive reasoning from these basic laws is a fundamental part of natural science. However, I think the difference between engineers and Darwinists is the starting point in what is perceived to be already known.

    Darwinists “know” that a Darwinian mechanism can create complex, information-rich systems, whereas engineers “know” that machines and engineered systems don’t happen by accident – they require intelligence and information – or as Dembski would put it, complexity and specification.

    The genetic engineering going on is a good example that some biologists can think like engineers. However, the challenge to Darwinists is to demonstrate scientifically that “natural selection” can indeed create new, complex, information-rich systems, rather than taking it as a given.

    No, I can’t agree here with your conclusions regarding the earth’s past. Powerful telescopes can tell what is happening on the far side of the cosmos umpteen million years ago, but they cannot tell us anything specific at all about life-forms in the earth’s distant past. Despite our evident knowledge of geology and fossils, our access to the earth’s biological past remains partial and incomplete, and barring time travel, is always likely to be so.

    The telescopic observations can demonstrate that the basic laws of physics and chemistry were the same in times past in the far reaches of the cosmos, thus giving us the principle of uniformitarianism. However, until such powerful telescopes can witness the development of life in the far past in other parts of the cosmos, we are none the wiser about the specific mechanisms for the development of life on earth. We still have to extrapolate from the earth’s present.

    The pattern of changes may be consistent with an assumed evolutionary schema, but your comment on tautology is quite correct. People are more or less assuming that which they wish to prove. I do not disagree with the fact that life-forms in times past were very different – what schoolboy was not fascinated with dinosaurs? (And when he grew up, Raquel Welch, but I digress. [Smile] ) It is the route to the life-forms of the present that must be demonstrated, not just assumed.

    Micropaleontology is definitely not my speciality, although if the fossil record here is totally consistent with classical Darwinism it is not something I have previously come across in my reading. Gould moved to a “punctuated equilibrium” model in order to try and match the fossil record more closely, whilst still remaining within the Darwinist camp.

    Even if you are correct on the evolutionary history of micro-organisms, it is still an extrapolation to apply that to hominid life-forms – we are very different to bacteria!

    Engineers do accelerated ageing tests on their products all the time. Can biologists not do the same on their theories?

I want to see fruit flies becoming something that is demonstrably not a fruit fly via a Darwinian mechanism.

    I admire the way you have turned the absence of present day evidence for gross speciation events into evidence for the correctness of Darwinism. I’m afraid I see such absence as a major flaw in Darwinism. As a theory it would appear to be neither testable nor observable nor repeatable, and certainly not falsifiable, rendering its scientific credentials suspect in my eyes.

    Glenn, you're welcome to ask, but I don't guarantee to be able to answer. [Smile] For a start, I don't have the specialist knowledge of animal biology and physiology that you have displayed in your posts. I have to approach this subject through a non-specialist route.

    I will give some more thought and come back tomorrow if health permits. In the meantime there is a huge amount of information at the Access Research Network Website.

    With respect to Cheesy's comments above on hominid fossils, one piece of research I would like to see is the present-day natural variation in hominid skulls (if such research doesn't already exist). I suspect that the natural variation will be found to be surprisingly large. That information may result in different assessments for some of the hominid skull fossils.

    I was using the faux amis example as an analogy. I appreciate that creationists are uncomfortable around analogy: I'll try to avoid them in future if they cause you problems.

    quote:


    Deductive reasoning from these basic laws is a fundamental part of natural science. However, I think the difference between engineers and Darwinists is the starting point in what is perceived to be already known.

    Darwinists “know” that a Darwinian mechanism can create complex, information-rich systems, whereas engineers “know” that machines and engineered systems don’t happen by accident – they require intelligence and information – or as Dembski would put it, complexity and specification.


    How does an engineer "know" that evolutionary systems can't generate 'complexity and specification'? Are these the same engineers who are exploring genetic and evolutionary algorithms to generate and refine complex systems?

    Most engineers that I know - and in the course of what may most kindly be described as my career, I've met many - seem perfectly happy with the idea that evolutionary processes are more than powerful enough to explain biological systems. What knowledge do you have that they lack?

    To reiterate my original point, which you have ignored: how do you know that your consideration of biology as cognate with engineering isn't leading you to falsely adduce the existence of sentience behind the former? How would you *check*? You are an engineer, so you know the dangers of assumption.

    quote:


    The genetic engineering going on is a good example that some biologists can think like engineers.


    And evolutionary algorithms and design work is a good example that some engineers can think like biologists. So?

    quote:


    However, the challenge to Darwinists is to demonstrate scientifically that “natural selection” can indeed create new, complex, information-rich systems, rather than taking it as a given.


    If you could define "complex, information-rich" systems, you might perhaps be able to advance that argument. Can you? But even then you have the whole business arse around face - the challenge is to explain the natural systems around us, a task where evolutionary biology is at least ten light years ahead of creationists, ID'ers and other apologists.

    How would *you* explain nested hierarchies, genetic and morphological correspondence between species, the ordered fossil records, and so on? So far, all you've got is bald statements that things are too complicated to be explained by evolutionary biology. The evolutionary biologists have enough data to choke a mutant star goat.

    Argument through incredulity cuts no ice. Argument through data, experiment and observation is much better.


    quote:


    <reiteration snipped>

    However, until such powerful telescopes can witness the development of life in the far past in other parts of the cosmos, we are none the wiser about the specific mechanisms for the development of life on earth. We still have to extrapolate from the earth’s present.


    Which is what I said. I don't understand your point here - and why do you think that 'witnessing the development of life in other parts of the cosmos' will be the same as the development of life on earth? It might be. It might be totally different. Why does this matter?

    quote:


    <more reiterations snipped>

    It is the route to the life-forms of the present that must be demonstrated, not just assumed.


    They're not assumed. There is massive genetic and other evidence as has been tirelessly demonstrated here and elsewhere. Making bald statements does nothing to counter them.

    quote:


    Micropaleontology is definitely not my speciality, although if the fossil record here is totally consistent with classical Darwinism it is not something I have previously come across in my reading. Gould moved to a “punctuated equilibrium” model in order to try and match the fossil record more closely, whilst still remaining within the Darwinist camp.

    Even if you are correct on the evolutionary history of micro-organisms, it is still an extrapolation to apply that to hominid life-forms – we are very different to bacteria!


    What of those differences affect the principles of evolution? Last time I looked, we had a very great deal in common with micro-organisms. Think about that next time you catch a cold.

    quote:


    Yet another careless use of the word “creationist”; a slippery elision into “evolution” on a thread about Darwinism; and an ad hominem caricature as well. [Frown] Hayward’s book is full of references to explicit scientific evolutionists who do not accept a Darwinian model.


    I take great care over my choice of words, and I got the 'goo to you' phrase from a creationist website. It didn't seem so different from 'particles to people', and I note that once again you have entirely avoided addressing the substantive point I was making.

    As for Darwinism versus evolutionary biology, as I've said I consider Darwinism an imprecise term and evolutionary biology as a better term for current mainstream thinking. You'll notice, if you care to notice, that I have not used Darwinism subsequent to that statement. If you care to define what it is about Darwinism you object to and how that differs from mainstream evolutionary biology, then we'll see.

    quote:


    You may indeed find a penny on the pavement, but the assumption in your argument is that you will continue to find more pennies, whilst simultaneously never losing any already collected, until your pound is complete. Your penny is only a simple analogy, so I won’t push it too far, but my fundamental point about extrapolation remains.


    You have yet to make any fundamental point about extrapolation. You have said it is inappropriate to apply to complex biological systems, you have said that it is inappropriate to apply it to hominids, but you have not in any way advanced the argument.

    I and others have repeatedly asked you what you think the limits to extrapolation are in your view and why: if you were to answer that, then you might perhaps begin to approach the outskirts of construction of such a point.

    quote:


    Engineers do accelerated ageing tests on their products all the time. Can biologists not do the same on their theories? I take your point about frogs not becoming dogs, but fruit flies can be bred at great speed. I want to see fruit flies becoming something that is demonstrably not a fruit fly via a Darwinian mechanism.


    Why? Where does evolutionary theory say that this is what we should observe with our current state of systemic modelling or practical experimentation? You have created a straw fruit fly and are tilting at it with the lance of incredulity (that's a mixed metaphor, by the way. Don't panic).

    quote:



    I admire the way you have turned the absence of present day evidence for gross speciation events into evidence for the correctness of Darwinism. I’m afraid I see such absence as a major flaw in Darwinism. As a theory it would appear to be neither testable nor observable nor repeatable, and certainly not falsifiable, rendering its scientific credentials suspect in my eyes.


    As I have repeatedly and explicitly said in this very thread, there are PLENTY of ways to falsify evolutionary biological theory. The fact that you choose to ignore these, or flippantly dismiss them as being beneath your intelligence, or just say "But it isn't so" doesn't really affect this fact.

    You should try and find some evidence for your position.

    Thanks for the link, Neil.

    Since homology is such a strong pointer to common descent and against intelligent design I went straight to Homologies.

    But this is an extraordinarily poor response to the question of homologies. As Darwin asked, why design a bat wing and a bat leg from the same basic bone structure (one bone, then two, then the carpals/tarsals etc along to the five fingers/toes). What is going on here? If you are making a wing, there are better ways to do it.

    With common descent it makes perfect sense, but from the intelligent design point of view it rests with the whim of the designer.

    I’m sure you’re well aware that the word creationist has a slippery and occasionally very pejorative meaning. Despite that it is peppered all over your posts. To remove any misunderstanding I suggest that you define your terms more accurately or use a different word. I prefer to stay well away from it unless the meaning is clearly defined in the context.


    Creationists: people who believe that God directly created different kinds of living things. And in that sense, I'm going to carry on using the word.
    In common Christian and Ship parlance creationist refers to young earth creationism. It is certainly not a neutral description, being heavily coloured with negative overtones and presuppositions.

    I have a lot of sympathy with what is called old earth creationism, or sometimes ancient creationism, but none at all for the young earth position - but then you knew that already.

    Since I consider that we have not achieved mutual respect, we have nothing further to discuss. I wish you well in your upcoming marriage.

    With respect to Cheesy's comments above on hominid fossils, one piece of research I would like to see is the present-day natural variation in hominid skulls (if such research doesn't already exist). I suspect that the natural variation will be found to be surprisingly large. That information may result in different assessments for some of the hominid skull fossils.

    Neil

    Let me get this straight- you're not a specialist, but you wonder whether the people who are have thought of someting blindingly obvious that you have?

    You don't know that. In fact you can be pretty sure that that isn't the case, as the vast majority of organisms die leaving no descendants.

    This is one of the times when sloppy language used by popularists rebounds on science - there are loads of people who seem to think that somewhere in Africa we are digging up our ancestors.

    We aren't - or we almost certainly aren't. At best we might be difgfing up individuals from the same species as our ancestors, bur frankly even that is very unliekly for anything more than a mere million or so years old.

    These days taxonomists treat fossils not as the ancestors of living creatures (or each other) but as evidence of end-points on the tree of life.

    If you think about it the same is tru for extant organisms - we can never see the complete ancestry and relationships of even a living wild organism. All we have is some evidence of its characters. We may have more evidence than for fossils (though not always - there are some commonly found extinct species better known than many rare extant species)

    quote:

    Is it possible to do any form of DNA testing on fossils?

    Yes, sometimes, on comparitively recent fossils, but that is not really a large part of how palaeontology is done.

    This is exactly the sort of question that palaentologists and taxonomists ask all the time.

    I am aware that ?natural selection? is responsible for moths getting darker, finch beaks getting longer, and bacteria acquiring resistance.

    This is going to sound patronising - but think of the scale of the thing. The amount of time available. The numbers of organisms involved.

    Biological numbers are big. Much bigger than the ones engineers and so on deal with.

    Scale again.

    If you can supply us with some kind of quantitative question - i.e. tell us how much different it has to be from a fruit fly in order for you not to count it as a fruit fly - than I could estimate how long it would take. That would be an intersting excercise.

    I assume you don't just speciation, because we can see that going on sometimes.

    Neil,

    Glenn, I’ve now done a bit more research into your question. On the subject of giraffe necks you’ll find a very brief and simple article here (scroll down to see the article). It does however scotch a few myths about giraffes based on field observations.

    With respect to the issue of DNA sequences, I understand that chimpanzees and humans are 99% identical in terms of DNA. In view of the massive behavioural, psychological and intellectual differences between chimps and humans, this DNA similarity does not necessarily carry much weight in establishing where chimps and humans came from in the first place.

    What it does indicate to me is the crucial part played by that other 1% DNA, indicative perhaps of a highly non-linear relationship between DNA and species. As an example of another wildly non-linear process, just contemplate what a 1% change across all your hard disk files would do to your computer. I guarantee that it would ruin your whole day. [Smile]

    On the specific subject of homology there are two articles at the ARN website by Wells and Nelson that will be of interest:

    The first article, entitled "Homology: A Concept in Crisis", is fairly technical. The argument is that in some cases apparently homologous features are controlled by different gene sets, contrary to what one would expect; in other cases the homologous structures are not seen in embryonic form, but develop later on through very different developmental routes; in yet other cases homologous structures in embryos go on to develop quite differently in the mature animal.

    Observe, incidentally, how the Darwinist Ernst Mayr defines homology in 1982:
    quote:

    A feature in two or more taxa is homologous when it is derived from the same (or a corresponding) feature of their common ancestor.

    In his definition Mayr starts with common descent as a given, whereas it was observations that gave us the concept of homology in the first place. So, is the cart before the horse? Wells and Nelson argue that these observations are very misleading.

    The second article, entitled “Is Common Descent an Axiom of Biology”, is longer and much more technical. This paper mentions the pentadactyl limb issue that you cite. Here is a quote on the issue of common descent:
    quote:

    …try the following thought experiment. Assume the truth of common descent, and then attempt to construct an empirical argument against it. No imaginable evidence one might bring to bear, however striking – e.g., organisms for which no transitional stages seem possible, multiple genetic codes – will be able to overturn the theory. If there really was a common ancestor, then all discontinuities between organisms are only apparent, the artifacts of an incomplete history. An ideally fine-grained history would reveal the begetting relations by which all organisms have descended from the common ancestor.

    With respect to the Intelligent Design movement and the fossil record generally, I can only speak as an interested and sympathetic observer. There is no dispute of the basic facts of palaeontology, nor of the age of the earth.

    In many ways ID is simply an umbrella term for those scientists who consider that Darwinism is an utterly failed scientific hypothesis, routed in a naturalistic philosophy rather than true observational facts. IDists consider that life is scientifically unexplainable without the admission of a philosophical teleology. A methodological naturalism that gives us the wrong answer is of no use.

    From what I can see, many IDists do accept evolution in the broadest sense of the word, meaning that the ancestors of present day life-forms were very different in times past. Even the Darwinian holy grail of universal common descent is admitted by some, such as Behe, whereas others repudiate it.

    However, all deny that the Darwinian mechanism of random mutation and natural selection alone has the creative power to form the complex biological structures around us. That is why I have commented on the imprecise language of some posters regarding “evolution” and “Darwinism”. The difference is crucial.

    For further information, in addition to the discussions at the Access Research Network site, I can recommend the ISCID (International Society for Complexity, Information and Design) website and their discussion forums.

    Although associated with the ID community, these forums display various scientific points of view, including those who repudiate Darwinism whilst subscribing to other scientific evolutionary models, and those who do not consider themselves part of the ID fraternity. There are even a few Darwinists posting. As far as I can see, the forums are heavily monitored to ensure that discussions remain strictly scientific. Enjoy and learn.

    Whyever not? Chimps aren't exactly the same as us, but they are more like us than either of is is like any other species. Chimps are more like humans than either is like gorillas.

    These are fascinating - the best known is probably the fore- and hind- limbs of tetrapods. Sorry, arms and legs. They are not truly homologous, being descended from different structures in the ancestral fish, but have come to resemble each other strongly. They also seem to have come under the developmental control of some of the same gene cascades (though we don't know the full details of this yet)

    The obviously anatomically not-at-all-homologous vertebrate & insect eyes are also controled in development by some of the same genes. (there is a very deep homology between vertebrates and insects but we are turned round - compared with them we are lying on our backs and speaking through our arses)

    They are wrong. I think they fundamentally misunderstand the way inference and evidence work in biology.

    It's not like a mathematical proof, with a chain of inference from axiom to theorem. A biological theory is a vast database of inter-connected and supporting opservations and hypotheses.

    The article does not appear to touch on the question that I raised about the neck of the giraffe which is "Why does the giraffe’s laryngeal nerve take a route down from the brain to near the heart and then up to the larynx? That nerve always takes that route in all vertebrates but in the giraffe it means the nerve is 5 metres longer than it needs to be to get from the brain to the larynx [because the giraffe has such a long neck]. There are no design reasons for all these kinds of similarity, but since the theory of evolution argues that adaptations build on what is already there then these kinds of similarity make sense."

    Perhaps one of the other articles you pointed out may have something to say on this kind of question. I shall read them.

    So far it does seem to me that the ID movement is simply anti-darwinian and has no remotely detailed alternate theory of the observations that neo-darwinian evolution seeks to explain. The appeal to 'intelligent design' is unaccompanied by any explanation of how that worked. The appeal to the idea that natural selection cannot generate 'complex specified information' is unaccompanied by any explicit theory about how the intelligent designer put the information in, and when he/she/it did so, and in what stages. Indeed at one extreme one can envisage a theory of ID which justs says that at every point where darwinism postulates favourable mutation just substitute the intelligent designer altering the DNA.

    BUt no-one really says much about these things as far as I am aware (I would be pleased to be corrected). This is a shame because there is much critical comment possible about how ID might be seen to fit with the observations. For example, the suggestion that the information needed for the bacterial flagellum was present from the beginning and then got switched on later is untenable because if it is not used and expressed then it cannot be preserved by natural selection. The information would be gradually corrupted by mutation, but because there would be no difference in the survival rate of a bacteria with a bad set of genes for a not-yet-used-flagellum and one with a good set for a not-yet-used-flagellum. So we would, at the very least have to postualte that if this is how it worked the intelligent designer inserts and preserves until needed the information for new structures. All very odd, frankly.

    I guess that for most plants pollen doesn't need to be carried the maximum possible distance, far enough to be pretty certain of finding another plant to pollinate would be good enough. Without the need for maximum distance, there'd be no selection pressure between random differences in pattern. Do the patterns influence ability of pollen to interact with flowers? ie: does the difference in patterns between different species limit cross-pollinisation? Because if that was the case then that in itself provides a mecahnism for differentiation of patterns between species as cross-pollinated plants are usually sterile.

    Assuming that the bees were already principal pollinators of the orchids, and were slightly more attracted to vaguely bee-shaped flowers than to less bee-shaped flowers then that results in greater pollination of intermediate vaguely bee-shaped orchids.

    Mmm... true, although does this explains the extent of the patterning (which is considerable). I do not see how it could be related to aerodynamics at all, though I admit a limited understanding of it. The patterning is not entirely related to the shape of the pollen, which one would assume was related to the aerodynamics.

    I suspect the answer to that, given the rather imprecise nature of bees' eyes, is "yes, definitely". Since each cell of the eye is either stimulated or not, they are not all that good at precise shapes.

    It's a bit like the way crows will mob herons, mistaking them for birds of prey (well, Bill Oddie said so yesterday - amazing what you watch when the bloody football's on). Siamese Fighting Fish can be made to attack a cardboard cutout if it has extensions similar to the species' fins, although the reaction is stronger the more lifelike the cutout is.

    Why assume that the patterning is to enable long flights?

    Anyway, for things as small as most pollen grains the shape has very little influence on flight. (Reynold's number & all that)

    I suspect that if there is any function to the patterns it is not about flight-time.

    Herons are predators, as both crows and Bill know. They will eat eggs - though they might have trouble getting them from a crows nest. Herons and crows might also compete for carrion.

    Anyway crows like them to know who is boss. I have seen with my own eyes a pair of crows driving a golden eagle away from a ledge they wanted to perch on.

    There were only ever two good reasons for debating this:

    Two, to try to get YECs to see sense. Well, I've long since realised that most of them have no desire to, and are quite happy to see me wear myself out trying to reason with them. Well, no more. If you are happy in your ignorance, then stay there. I just don't care any more.

    So. That's it. I doubt I'll be posting on CF much at all now, since this was my main reason for coming here.

    In honour of Karl's retirement I spent some time the other evening on the strongly pro-Darwinist Talk Origins website. The beautiful natural arch on the home page links in to my post below.

    Earlier on this thread I used the phrase “complex, information-rich systems”. I’ll try and elucidate what I meant by that with reference to my own technical speciality, which is as a civil engineer specialising in the structural integrity and safety aspects of nuclear installations. By structure, here I mean load-bearing structure, with load as in gravity, wind, specialist machinery, earthquake, accidental impact, or whatever.

    In structural engineering there are two basic types of structural form: the tower (as in a tall chimney; a radio mast; a multi-storey building) and the bridge (whether in tiny form, such as a floor joist in your house, or on the huge scale of a major road bridge, or even in the form of an arch – the key point is that it spans a gap).

    I will illustrate both of these forms as they occur naturally in geological processes. The important point to note up front is that these load-bearing structures have been produced by the natural forces of wind and wave erosion which are clearly undirected by any purposeful intent that we can discern. At the atomic level this erosion process is governed by simple laws of physics and chemistry.

    Here is the tower: a natural occurring sea stack in the north of Scotland, called the Old Man of Hoy.

    Here is the bridge: a naturally occurring sea-arch in Dorset on the south coast of England, called Durdle Door.

    My approach to information theory as an engineer is quite basic: I measure it simply by how much paper the project requires, in the form of survey dimensions, construction drawings, material schedules, substantiating calculations, temporary works etc., in order to build a full size replica.

    My response as a civil engineer for both the Old Man of Hoy and Durdle Door is that I would need relatively little information. A handful of geometrical dimensions and some basic properties of the rock would suffice, in order to match the loadbearing behaviour. Of course I would have to build in concrete, since hot liquid rock techniques are not very advanced. [Smile] A concrete structure would also erode away more quickly than the natural rock, but that’s an issue of durability, not strength.

    Now compare that to a comprehensively engineered structure, such as the high-rise structure that we have all seen as it was destroyed, the late lamented Twin Towers in New York. I have been to a technical presentation on that collapse. The outline of the aircraft relative to the floor layout is much bigger than you think - the video footage is very misleading. These aircraft were huge, and fully loaded with fuel, so fire damage caused the eventual collapse.

    The engineering information content on that project was many orders of magnitude greater than would be necessary for the Old Man of Hoy. Huge numbers of small components, some identical, but many with small but vital changes, were needed; precision engineered connections that wouldn’t work if they were out of tolerance; a sophisticated shell structure that remained standing for over an hour despite the impact of a huge aircraft for which it was never designed; and of course, the Twin Towers were hollow, occupied by people on numerous floors.

    It all adds up to an engineered system with an impressive amount of specific and complex information, especially in comparison to the Old Man of Hoy. For further evidence, see here. Are these formations natural? Of course not. The conclusion I come to is that geological processes and the natural forces of wind and wave cannot create information-rich engineering structures out of rock.

    So far I have been talking about geology, not biology. However, since “geological processes and the natural forces of wind and wave” boil down to the basic laws of physics and chemistry, I remain very sceptical that natural processes alone can create biological systems of considerably greater engineering complexity than the Twin Towers. The informational content in living things has to come from somewhere. For this reason I am very sympathetic to the outlook of the Intelligent Design fraternity.

    Sorry FS, I fail to see what relevance erosion has to biology. Maybe you should stick to engineering.

    Why does it have to? Why can't information come from nothing? It certainly doesn't appear fully formed, information is constantly being added in infinitesimally small amounts - add long periods of time and you get as much information content as you need, all without any inexplicable leaps in information quantity or any irreducibly complex systems.

    But your reason is unclear, Neil. What has this to do with Darwinian evolution? You make no mention at all of the central process that results in the accumulation of information by organisms, namely that of natural selection. The geological features that you refer to are not systems that replicate themselves.

    The use of the term ‘information’ in the context of biology is fraught with potential misunderstanding and ambiguity. But it is a popular term, and there is some sense to it, so the first thing to say is if one is going to insist on that term then natural selection is the means whereby organisms accumulate new information.

    As an example let’s start with a population of organisms. These organisms have a particular gene which has the information in it that, in effect, says: 'make this protein in this way (call it way A)' and that protein results in the organism having a particular quality – say that it can absorb oxygen into its bloodstream.

    As a result of random mutation this particular gene of a member of this population changes. The information in this version of the gene now says, (as a result of purely random change): 'make this protein in this other way (call it way B)'
    In this particular case the change happens to be advantageous to this particular type of organism in this particular environment. Perhaps it means that the bloodstream is able to absorb even more oxygen than by way A and that this enables the organism to move faster, or for longer.

    The organism that now possesses this version of the gene is then relatively more successful than its fellows in reproducing successfully. It passes this advantageous gene on to its offspring. With time and successive generations the more advantageous version of the gene increases in the proportion of the population that have it, because its possessors breed more successfully than those that do not.

    Eventually the great majority of the population have this gene and the traits that it confers or improves.

    The organisms in the population in this example began with information that said 'make the protein in way A' and wound up with the information 'make the protein in way B' which, in this organism in this environment is better information than the earlier information. The genetic make up of this organism has (to speak metaphorically) learned that way B is better than way A.

    That, in a rather over simple way, is how random mutation plus natural selection plus replication provides information to the evolving organism.

    What needs to be added to this is things like gene duplications followed by advantageous mutations leading to new functions for one of the copies (as discussed in earlier posts on about page 10 of this thread).

    The question that is often asked about Darwinian evolution is ‘where does the new information come from?’ It comes from a random event like a mutation which acts rather like a random guess or trial and selection weeds out the bad guesses and reveals them to be ‘errors’ as far as increased reproductive success goes. Trial and error where successes are preserved can accumulate a great deal of information over time.

    PS
    I am drafting a response on the papers on homology, Neil. But pressure of other work is delaying it.

    An interesting aside: NASA is using evolutionary principles to design spacecraft antenna. Seems nobody told these engineers that such things are impossible.

    "The software started with random antenna designs and through the evolutionary process, refined them. The computer system took about 10 hours to complete the initial antenna design process. "We told the computer program what performance the antenna should have, and the computer simulated evolution, keeping the best antenna designs that approached what we asked for. Eventually, it zeroed in on something that met the desired specifications for the mission," Lohn said.

    ...

    "The software also may invent designs that no human designer would ever think of," Lohn asserted. In addition, the software also can plan devices that are smaller, lighter, consume less power, are stronger and more robust among many other things - characteristics that spaceflight requires, according to Lohn. "

    http://www.spaceref.com/news/viewpr.html?pid=14394

    So here we have a solid demonstration that randomness applied through a selection process -- explicitly modelled on Darwinian ideas -- can indeed 'create information', however you define information. It may even be able to design things that no human would come up with: I know the IDers 'argument through incredulity' is no good anyway, but this further underlines its weakness.

    Excellent example Rex. But let us prepare ourselves for some supporters of Intelligent Design to say; 'ah yes but the program was made by an intelligent person!' This response misses the point entirely, of course, in that the outcome was not predicted, nor specified, nor designed, by any intelligence whatsoever. The model parallels natural selection superbly.

    FS, I have been trying to understand this post over the weekend. My conclusion is that I know as much about engineering as you appear to know about biology and geology.

    I don't really understand how you can compare a complex human built system and suggest that it is more complex than a geological feature simply on the basis that you can replicate it. An Old Man of Hoy made of concrete is not the same thing, and does not approach the same complexity in terms of its geology or biology.

    As a proper comparison, maybe you should consider the complexities of starting with a bed of layered sedimentary rock and work out the pressures needed to create a stack with only a few million years of wave action to use.

    Further, in contrast to you, I would consider the geological feature to be extremely information rich. Soil, the top metre of material above the rock layer, is in itself the most complex system known to man (not that I have an interest or anything [Biased] ) - and something which we are only starting to understand. Add to that the many things that the geologists would be able to find interesting about the stack, data from botanists and zoologists, geographers and the other multitude of relevant disciplines and the amount of information is mind boggling.

    What does this prove? Nothing really. There is no engineering project that could even approach the complexity of millions of years of erosion and deposition. Unless you are called Slatibartfast, of course.

    That's a good way of looking at it.

    Anyone who's programmed an analogue musical synthesiser will know two ways to produce a coherent tone - either start with an oscillator, or filter down white (ie, random by definition) noise. The results can be identical, even though the initial source of the signal is wildly different.

    This can even happen entirely naturally - if you swim through a tunnel connected to the sea (I've done this on Gozo, where there's a long tunnel through the cliffs connecting an inland sea to the outside) you can hear the sound of the waves change dramatically as you go through. The tunnel forms a natural audio filter which cuts down certain frequencies present in the white (ish) noise of the waves. The noise within the tunnel is certainly more ordered than that outside: this effect and others related to it is used in geophysics and oceanography, and also in medicine to determine the state of your personal pipes.

    This tallies with what I understand of Darwinism. I have no problem with this mechanism for small changes. It is when these small changes are extrapolated into the huge evolutionary changes necessary for all the diverse genera that I get all twitchy. [Smile] My reading of the evidence from artificial selection and animal breeding is that there is a distinct boundary limit beyond which no further change is possible.

    Here is a fuller description of the modern neo-Darwinist synthesis at the Talk Origins site. I am particularly interested in the phrase (my emphasis):
    quote:

    It (i.e. the modern theory of the mechanism of evolution) recognizes several mechanisms of evolution in addition to natural selection. One of these, random genetic drift, may be as important as natural selection.

    Is random genetic drift a scientific speculation being intensively researched at the moment? Do we not know for certain?

    The Talk Origins site mentioned that, in both humans and chimpanzees, the same gene has been switched off, so that we cannot manufacture vitamin C ourselves. We need to acquire it in our diet, as do chimps. That could be evidence for common descent, or it could be that both changes occurred independently.

    One thing I would note is that there is an important difference between increasing the information and changing the information. The genetic information which makes protein B in the improved model does not contain more information than that which makes protein A. It is simply a different but grammatically acceptable variation in the existing gene. A 1.4MB floppy disk can contain all sorts of different information, but not more than 1.4MB.

    This was an interesting link, but unfortunately it did not give me enough technical information to assess exactly what software algorithms and design techniques are being used. As a user of specialist technical software myself, I think the quoted phrase:
    quote:

    "The software also may invent designs that no human designer would ever think of,"

    needs to be taken with a large pinch of salesman’s salt. I was certainly smiling at that point. Artificial intelligence on this scale is a long way off, if ever.

    What the software is probably doing is extensive optimisation of some trial designs following miscellaneous rules and deterministic theories for the subsequent technical performance of a given design. In my opinion this software is inventing nothing. All technical information, design algorithms and theoretical understandings are programmed in from the start.

    What the software can do is to consider millions of possible options in a short space of time. It is not dissimilar to those computers that can play chess and beat a grand master. The computer has to be told the rules beforehand. We can then exploit the massive calculation power that it offers – and beat the grand master with a computer. But who invented chess in the first place?

    For a similar computational approach I can recommend the section in The Blind Watchmaker where Richard Dawkins describes his various computer simulations, using the phrase Methinks It Is Like A Weasel, and then his fascinating geometrical shapes called biomorphs. The intelligent application of small incremental steps can certainly construct very complex shapes and systems.

    However, Dawkins seems unaware that he is modelling a situation with substantial inbuilt constraints on where it may end up. In effect he assigns a creative intelligence to the power of natural selection – it knows where it is going. I do not consider that his computer models reflect the natural environment at all, which is random and uncontrolled.

    I tried to keep the specialist technical content of my post to a minimum, but I’m sorry for the confusion. I’ll try and explain a bit more.

    Firstly, I moved into the area of geology because I have no problem at all acknowledging that geological processes similar to those that we observe today have been going on for 4.6 billion years. The laws of physics, chemistry and geology are well understood. My basic question is just how good a structural engineer is undirected and unintelligent geological action.

    In my full size engineering model of The Old Man of Hoy, I was not considering the soil ecosystem, nor whatever flora and fauna may be present. There is certainly information there, but very little pertaining to a loadbearing engineering structure. I am focussing on information relevant to structural strength, such as overall size, cross-sectional shape, rock stratum depth, precise rock type, the location of geological joints, etc. All these features could be modelled, even in concrete.

    The engineering system I was considering is the loadbearing aspect of a tower structure – a vertical cantilever in technical terms. I was imagining a huge finger at the top of the tower trying to push the thing over, just like the Leaning Tower of Pisa. What are its strength, stiffness and vibrational properties? How does it respond when Al Quaeda fly a jet into it? How hard does the finger have to push before Orkney loses a famous landmark? [Smile]

    These loadbearing aspects could certainly be matched in a full size concrete model. If you prefer, and you give me lots of dynamite and large mechanical breakers, I could sculpt a full-size model out of the nearest cliff. It would take me a lot longer to do that than constructing in concrete, but the time needed would still be a lot shorter than the time natural erosion has taken.

    As an aside, if anyone has any interesting links to interesting geological formations, I would be happy to comment on them from a structural engineering perspective.

    A narrow bandwidth filter on white noise will produce an approximately sinusoidal signal. True white noise contains no information, since it is random and uncorrelated.

    If one is looking for a certain frequency, then one can construct the filter accordingly. That is intelligent design. However, as far as I can see, Darwinian natural selection gives us a random filter based on environmental pressure. Only very occasionally, as in Glenn Oldham’s protein A and B example above, does it strike gold.

    Part of the problem here is an accurate technical definition of what we mean by information in an engineering system, or indeed a biological one. Since the word is used in common parlance in loose ways it is easy to come unstuck here. A single musical note contains no information in a technical sense, any more than a single note makes music.

    For a scientific definition, information needs to be observable, measurable and quantifiable, in just the same way that a file on a hard disk has a specific size and content encoded into the magnetic particles of the disk. I believe that parts of the ID fraternity have produced some relevant mathematical models about information, but I have no further details.

    Punk-eek is certainly part of the neo-Darwinist synthesis. A variety of it, not an alternatve to it.

    "Saltationism" has meant a number of different things over the years,. In its early 20th-century form, it was used by people who misunderstood Mendel to argue against Darwin. But there is a sort of neo-saltationism around (not that they woudl use the word) which stresses the possible importance of like large-scale mutations such as chromosomal inversions.

    It is at least possible that these have sometimes created barriers to breeding between populations living in the same location - one mechanism for the elusive sympatric speciation (Yes, it can happen. No, we have no evidence that it ever does much)

    The main opposition to the adaptionist view of evolution has come from proponents of neutral evolution - look for references to Kimura.

    But this is really still within the Synthesis, or at most an addition to it, not a disproof of it.

    We know for certain that it happens. What we don't know is how important it has been in causing speciation and specialistation.

    These things are "natural laws" of the sort that physics investigates. They are descriptions of contingent history.

    NB in the case of humans and chimps, genetic drift alone - so-called "neutral evolution" could account for ALL the observed genetic diffrences between us. In fact more than are observed, our genomes are probably more alike than would be expected in the absence of selection.

    That doesn't mean that there has been no selection - but it is, to say the least, impraobable that a new mutation will proceed to fixation (i.e. become universal in the population) more quickly in the absence of selection than it woudl hav if there had been selection. So the expected rate of accquisistion of new mutations from neutral drift is a good lower limit on how fast we could expect change to occur under selection.

    That's just one example of millions of known mutations. You can't tell descent from one or two - but when many seem to vary in a nested way, it's a Big Clue.

    There are at the very least hundreds of characters shared by humans and chimps and no other primates. And many more shared by all the apes and no other primates. And others shared by apes, old world monkeys, and no others. And so on.

    For example, human globin genes, the homeobox genes, the ribsomal RNA genes, some spider-web genes, literally hundreds of metabolic genes.

    In plants it is quite common for whole chromosomes, or even the whole genome, to duplicate. After a while many of the duplicate genes are randomly knocked out (because missing one copy of multiple genes coding for the same product may not have a deleterious effect), others accquire new function.

    Fortunately, there is much information available about what an engineer means if he says he's using evolutionary (or genetic - same thing) algorithms.

    You precisely miss the point. No intelligence, artificial or otherwise, is required. That's why this approach yields results where some of the other approaches, such as knowledge systems, have failed.

    quote:


    What the software is probably doing is extensive optimisation of some trial designs following miscellaneous rules and deterministic theories for the subsequent technical performance of a given design.


    No it's not. That's not what they said: they said randomness followed by evaluation for fitness. If you don't believe them, then that's up to you -- although arguments from incredulity are wearing so thin they count as nanotech by now -- but perhaps you could consider what it means if it works the way the NASA engineers say it works?

    quote:


    In my opinion this software is inventing nothing. All technical information, design algorithms and theoretical understandings are programmed in from the start.


    Well, I'll take your opinion under advisement, but it would have more weight if you had some facts behind it. The engineers who produced the system are on record as saying something completely different, and their jobs are on the line. They aren't doing this for fun, and presuming that they wish to be taken seriously by their peers then they aren't deliberately (or accidentally) misrepresenting what they're up to.

    No 'design algorithms' were programmed in aside from the 'take a device, randomly modify it, assess it, select it if it is better than the rest, repeat' That's how this stuff works, after all, and that's how natural selection works.

    And nothing in the system needs 'knowledge' of *how* the finished article works - no 'intelligence' required - just how to change, test and compare.

    I don't know if you've ever done any antenna design (oddly enough, I have), but doing it from first principles is bloody hard. It's much easier to take an existing design, modify it and run it through a simulator.

    When you've also got to take other factors into account, like weight, size, materials and so on, mechanising the evolutionary approach seems a very sane way to approach the problem.

    Tell you what, since you're disinclined to take my or NASA's word for it, why don't you have a look at some of the software freely available on the web that does genetic algorithmic antenna designs? You can examine it and decide for yourself how it works.

    http://www.qsl.net/wb6tpu/swindex.html has a link to instygo2.exe, the Yagi Genetic Optimiser 2, of which the designer says: "YGO2 (YAGI GENETIC OPTIMIZER II) designs optimized Yagi antennas using one of the most recent and powerful techniques in applied electro- magnetics: a genetic algorithm. A genetic algorithm mimics natural selection ("survival of the fittest") by creating generations of Yagi designs in which the best designs ("individuals") pass their design parameters ("genes") onto the next generation in such a way that better and better antennas are the result. GA optimizers can produce remarkable results not achievable with any other design technique. Genetic algorithms are superior to deterministic optimzers, and they are easily implemented on a PC."

    Unambiguous, eh? It's a bit technical, but "as a user of specialist technical software myself" I don't see you having a problem. I look forward to your analysis as to whether the software is doing what the designer says it's doing.

    What the software can do is to consider millions of possible options in a short space of time. It is not dissimilar to those computers that can play chess and beat a grand master. The computer has to be told the rules beforehand. We can then exploit the massive calculation power that it offers – and beat the grand master with a computer. But who invented chess in the first place?


    It's not that dissimilar, certainly. And using these simple rules - nobody would claim a chess computer had true intelligence - the machine can 'outthink' humans. So we have evidence that a mechanistic approach to a complex problem can produce better results than humans: thus, it should be no surprise when the mechanistic process of evolution produces better results than we can achieve.

    Who invented the basic rules of chess? I don't know, and neither do you. Where did the basic rules of physics come from? I don't know, and neither do you.

    For a similar computational approach I can recommend the section in The Blind Watchmaker where Richard Dawkins describes his various computer simulations, using the phrase Methinks It Is Like A Weasel, and then his fascinating geometrical shapes called biomorphs. The intelligent application of small incremental steps can certainly construct very complex shapes and systems.

    However, Dawkins seems unaware that he is modelling a situation with substantial inbuilt constraints on where it may end up. In effect he assigns a creative intelligence to the power of natural selection – it knows where it is going. I do not consider that his computer models reflect the natural environment at all, which is random and uncontrolled.


    I'm looking through my window outside at the natural environment, where a large weather system is sweeping across London. Random? Uncontrolled? The environment is heavily controlled by physical laws, which also produce notable unrandomness at all scales from atom to galaxy.

    For a living being, the rules are complex and ruthless: if you can't extract energy from the environment, can't defend yourself from weather, predators or natural hazards, or can't successfully procreate, you're stuffed. Not much random there.

    That's exactly what Dawkins was demonstrating: randomness filtered through rules produces change that can be constructive. No sense of direction required, unless you consider 'survival' as a sense of direction. The randomness doesn't apply equally to all parts of the system. Just because there's a random element at one point doesn't mean it's equally important everywhere.

    (The trouble with Dawkin's analogy is the same trouble as all analogies of this nature - at some stage, someone will say "Naw, look, there's a human involved in constructing the analogy - therefore there must be an intelligence involved in real thing". Hopeless logic, of course, belying a thundering incomprehension about analogies, but it's amazing how often it happens.)

    This is a technique known as a genetic algorithm, so called because of the parallel between it's method of operation and genetic evolution. It is inaccurate to call it artifical intelligence, as it is distinctly anti-intelligent. It is setting a problem (say "what is the optimum dish size and shape to communicate with a probe?") then providing a mimimum of intelligent input (ie: the ideas and experience of communications engineers).

    It is a pure brute force computational method that includes some way of coding the antenna shape, a means of modelling it's functionality and a selection filter that is simply "does this configuration perform better than the others?". Then the best models are "bred" and random mutations introduced and the cycle continued.

    These factors contain a considerable amount of information. A concrete facsimile may have the same shape, but it will be a considerably different structure with much less informational content. The structure of something like the Old Man of Hoy would depend to a large extent on very small components just like a tower block ... the slight differences in minerals that make some rocks more resistant to erosion than others for example. Even the soils and plants you ignored have helped govern the present shape of the tower in the way they affect erosion.

    My question would be though - if those passages aren't an appeal to ID what are they about?

    ---
    *you know the one about the heavens preaching

    The passages are, I assume, Romans 1:20 ("For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.") and Psalm 19:1 ("The heavens are telling of the glory of God; And their expanse is declaring the work of His hands.") and surrounding verses.

    First, I think it should be understood that these are words written by and for people who already believe in a Creator God. They are an appeal to people who know God exists - "look at the world around you, the heavens above, and from them something of the nature of God is plain". They are not appeals to people who don't believe in God - "look at the world around you, the heavens above, and from them the existance of God is plain".

    Second, both are linked in very strongly with the theme of morality and Gods law. Romans is set within a section declaring that Gods wrath against people isn't against the ignorant, but against those who have sufficient evidence to recognise and respond positively to God yet have chosen not to do so. Psalm 19 uses the wisdom, power and perfection shown in Creation to point out the same characteristics of the Law of God.

    Neither would have any power to speak to someone who looking at the universe sees nothing but apparent order brought about by random events and the immutable laws of physics. Neither passage, nor any other I can think of, would support the idea that one can prove the existance of God from the existance and nature of the physical universe. There are plenty of passages of Scripture which would support the idea that those with faith in God can look at the physical universe and learn something true about God from that (though, by no means all there is to know about God which is why we need his self-revelation supremely by Incarnation).

    I have no doubt that the engineers responsible for the implementation of an “evolutionary” algorithm in their design software are very proud of it. I’m certainly not accusing them of misrepresenting anything. All I’m saying is that enthusiastic self-reports from successful engineering project teams need careful examination, especially if their language uses some unusual engineering terminology borrowed from other scientific disciplines.

    If you have experience in antenna design, then you are one step ahead of me. Words like monopole, dipole and multipole have emerged from my memory.

    I presume that the “clan” of all possible antenna designs comes in “families” of different patterns (i.e. monopole or dipole or whatever). Within a given pattern (a “family”), a particular antenna design can be characterised by a string of N parameters describing the size, shape, material, functional limits etc. In this respect an antenna design is no different to a design for a girder or a pump, or any other engineering system whose technical content can be reduced to a string of N parameters applicable to a particular pattern.

    Here is a description of evolutionary algorithm from the link that you provided, with my emphasis:
    quote:
    Evolutionary algorithms are stochastic search methods that mimic the metaphor of natural biological evolution. Evolutionary algorithms operate on a population of potential solutions applying the principle of survival of the fittest to produce better and better approximations to a solution. At each generation, a new set of approximations is created by the process of selecting individuals according to their level of fitness in the problem domain and breeding them together using operators borrowed from natural genetics. This process leads to the evolution of populations of individuals that are better suited to their environment than the individuals that they were created from, just as in natural adaptation.

    Evolutionary algorithms model natural processes, such as selection, recombination, mutation, migration, locality and neighbourhood. Figure shows the structure of a simple evolutionary algorithm. Evolutionary algorithms work on populations of individuals instead of single solutions. In this way the search is performed in a parallel manner.

    So the first point to emphasis is that there is a metaphor being used here. Just because the software says “evolutionary” algorithm does not mean that it necessarily reflects accurately the processes that have actually taken place in biological history. Clearly, however, it has taken its inspiration from a Darwinian model.

    The second point is that each design is presumably characterised by a string of N parameters, and only N parameters. N will vary depending on which “family” the proposed design comes from. The software may even be able to consider different design families simultaneously, but that doesn’t affect my overall point.

    The start parameters of the first generation are presumably generated randomly by the software rather than being fed to it in the form of a trial design. Subsequent generations can be generated by the software from the existing population in a process involving selection, recombination and mutation. This mimics the effects of breeding.

    Each generation is tested against the programmed technical criteria for “fitness”, and the whole process then repeats. In this way the design performance of huge numbers of trial designs can be assessed in an extremely efficient manner. No argument there at all.

    But let’s look at the inbuilt constraints on this process.

    Firstly this software only applies to an antenna system described by the N parameters needed. The initial parameters for the first generation may indeed be generated at random from within the software, but it is likely that the software has in-built limits for the key parameters involved, based on practicality if nothing else. An antenna that is too large or too small to be built is of no use to us, so the software rules it our from the start.

    The technical criteria against which “fitness” is assessed at each iteration are programmed in from the start. In principle the engineers tell the computer what is fit and what is not, through their design theories. This is essential information that must be programmed in, otherwise the computer has no basis on which to say one design is any better than any other. The arithmetical donkey work alone is done by the computer. The engineer is still the master at the level of ideas.

    The process of selection, recombination and mutation will follow a programmed route. Again, the software is programmed to allow for a certain range of possibilities which the engineers are calling “random”. Note that the word “random” is being used rather loosely here, much like so-called “random” numbers on my calculator are always between 0 and 1. The software can only generate the next generation within its programmed constraints, and there is no possibility of generating a design outside those limits.

    Millions of iterations later we still have an antenna design, or a population of antenna designs, but now they are highly optimised and very useful. However, at no point can the software evolve anything other than an antenna design, which is what it started with. Whatever numbers it throws out will always be an antenna design. Even if it ran for all of eternity, it will not morph into producing parameters for, say, a pump design.

    A considerable amount of intelligence was needed on the part of the mathematicians, engineers and programmers to produce this software using “evolutionary” algorithms. I’ve not had personal experience with such algorithms, but I am happy to accept for some technical problems they may indeed represent a vast improvement on earlier approaches.

    However, although “evolutionary” algorithms have taken their inspiration from biology, I do not think that they are a model of Darwinian evolution, unless you are prepared to accept that natural selection can operate in a mathematical fashion according to intelligently determined numerical rules with a clear sense of purpose behind them.

    At school I was still using a slide-rule and log tables, so I am not denying for a moment that computers have vastly more computational power than humans. In that sense computers can produce better results – but only in accordance with the constraints that we give them. In any case, the first rule of computers is “garbage in equals garbage out”.

    My point about chess was that human beings invented chess in the past. The rules are the human-derived constraints that govern the movement of pieces and the flow of the game. That took intelligence, something present day computers certainly do not have. Without us there would be neither chess nor computers.

    You may want to ask your first question to Darwinists, too. [Smile]

    I think that a short answer to your question on ID is the recognition that in certain circumstances a methodological naturalism completely fails to provide the right answer to certain questions, especially ones where we know what the correct answer is.

    Here are some rock formations. It is immediately obvious that the most comprehensive understanding of geology, erosion, wind, weather and the physical sciences generally will never correctly explain such formations. We know for a fact that they were deliberately formed by intelligent beings – humans – in honour of other humans.

    The same category mistake would be made by those who open a Bible, only to insist that the discussion be limited to the chemistry of printers’ ink and the science of paper-making and book-binding. What they say about ink and paper may well be very true, but it is incapable of giving a full explanation of the Bible, namely that the ancient authors wrote in order to communicate a message of faith to others, and to record it for posterity.

    ID is far more than throwing one’s hands up in the air and saying “God did it”. Here is a very short note from William Dembski on some relevant research issues suggested by an ID paradigm.

    As I said in my reply to your point about Dawkins weasel demonstration (a reply you seem to have missed - don't worry, it's coming up again later), this 'essential information' does not need to be intelligently provided. In the natural world, the 'information' is the environment in which a particular species lives. In the antenna design software, the test is 'how well does the antenna perform' (and, presumably in the NASA example, 'how light/small/spaceworthy is it?' - fitness can be a very complex thing). That one is set by engineers and another by nature does not mean that nature is the product of engineering. That is a basic logical fallacy.

    What the evolutionary algorithms show is that the basic idea behind evolution is sound.

    quote:

    There's also no possibility of natural selection on Earth producing a design outside its limits. Will we ever see a methane-breathing giant balloon animal capable of living in the upper atmosphere of Jupiter evolve on Earth? No, any more than Jovian natural selection will produce a bunny rabbit.

    So I don't understand what your point is here: you appear to be saying that evolution can't operate outside its own constraints. No, it can't, and that'e entirely consistent with evolutionary theory.

    Were animals to appear that *did* break evolutionary constraints, that would be an indication that evolutionary thought is wrong. IDers claim that this has happened: unfortunately, they cannot demonstrate it. Evolutionary thought has proved more than powerful enough to answer all their objections (and design antennae on its tea break).

    quote:

    You are correct: it won't (or at least it is very improbable). Again, you're stating basic evolutionary theory. The system will not select for things which are not conducive to fitness. However, if you asked it to select for antennae that were also pumps, then it might - and probably would, given enough time. That's setting the environment to select for a different class of fitness.

    It's very simple. The antenna design software uses evolutionary ideas to select for a better antenna. Natural selection uses evolutionary ideas to select for species better able to survive in their environments. Is it surprising that the output of the latter is more diverse than the former?

    The people who build the software consciously model that software on Darwinian evolution, so your claim that it is not so modelled is prima face false.

    By your logic, as soon as you model a thing you're proving that the thing is of intelligent origin. That is prima face absurd.

    Of course they use their intelligence and a sense of purpose in building a model, that's what building models (and intelligence) is all about. How else would you do it? But it is a model - and the thing that is modelled does not automatically acquire the attributes of its modellers. (It is hard indeed to conceive of the world where this would be the case: you appear to be drifting into sympathetic magic and voodoo, rather than engineering.)

    Unfortunately, you appear to have missed what I said about Dawkins and the weasel, when I replied to this point the first time you brought up.

    As you missed it, here it is again.

    Well, whether Karl Popper's theory applies to unrepeatable events is a whole other thread.

    But, since you asked, then, yes, if you really wanted to and threw a lot of money at the project, there are experiments which could seek to falsify the idea of irreducible complexity. An example is the attempt to synthesise amino acids by running electrical currents through a mixture of gases of the composition thought to be present at around the time when life is said to have first formed.

    A more likely way that it could be falsified would be if a living organism less complicated than a mitochondrion were found. But since that wouldn't be a designed and controlled experiment I guess you wouldn't consider that science.

    I've answered from your perspective, so now will you tell me what's wrong with irreducible complexity using my definition of scienctific method? My definition being to look at all the available evidence and decide logically what the most likely explanation is.

    For example, the biochemical structures labelled 'irreducibly complex' by some people could have been formed through 'scaffolding' - structures which no longer exist but once aided in putting together the various parts of the protein.

    Lets face it, intelligent design is not really a fully grown theory of the development of the diversity of life - it is an ideologically motivated, desparate attempt to criticise another established theory that works very well.

    Rejecting the modern evolutionary synthesis, which is a comprehensive, lucid, elegant and adaptable theory which explains a huge amount about genetics, biogeography, diversity and natural history on the basis of some spurious and (frankly) subjective idea like 'irreducible complexity' is ridiculous. Intelligent design theory is a speculative idea that does not have the tiniest fraction of the explanatory power of the modern synthesis of evolutionary theory.

    Well it's still something of a mystery how protein tertiary and quaternary structure is determined, so I'll reserve judgement on that point. But I've yet to hear a decent explanation for how half a Krebs cycle would have enough of a selective advantage to stick around until the other half evolved, or two thirds of glycolysis.

    No, it isn't a theory which explains everything. It just suggests that (assuming God was involved at some point) God took an active role in the origins of life, rather than the 'clockwork toy' model where He sets everything up for the big bang then sits back and passively observes.

    Well, that's OK then ... because I believe in a God who takes an active role in the origin and evolution of life and doesn't sit back and passively observe his clockwork toy (that belief would be deism not theism). The thing is, I see no reason to assume that a scientific understanding of the universe would leave explicit evidence of his action - which is the assumption behind ID as I understand it.

    Re the issue of the evolutionary software...

    I confess to knowing little about the mechanics of the programming, but AFAIUI, the algorithm randomly mutates then the result is tested to see how well it works (presumably against some set values).

    That being the case (please correct my faulty understanding someone who knows), surely the only thing it shows is that given the right circumstances, mutation can cause evolutionary change for the better.

    Now this gets to the crux of the matter. Dawkins says evolution occurs because he can imagine a circumstance where it might beneficial change leading to speciation. This program shows that happens, given certain conditions.

    The debate, therefore, should therefore be whether these ideas and algorithms can accurately mimic the conditions in the natural environment.

    I would argue that they do not. Comparing a simple computer program, which mutates fairly randomly against a given (and small) set of criteria is totally different to the natural environment, where organisms are under a miriad of selective pressures, which might be constantly changing. Creating something artificially is not the same as proving it happens in nature, especially when - as it appears in this case - known features are not directly being modelled.

    The Krebs cycle is found only in mammals, if I recall (and it is possible that my recall on this point is imperfect - my limited and fairly unpleasant experience of doing a biochemistry paper was some years ago). In that case it evolved in a context of an already incredibly sophisticated biological system, and it may have (again, I am no expert) been a development of another biochemical pathway. The biochemical pathway that evolved into the Krebs cycle (assuming for the moment that there was one, and that it happened without divine intervention) may have had a different function, or else may have been a longer and more clumsy process that was refined (ie the 'scaffolding' I mentioned before)down to the relative elegance of the modern mammalian process.

    And the example of the Krebs cycle is really nit-picking and misleading in a larger context. There are millions of things that evolution cannot explain because (a) The tools that biologists have to peer back into the past are imperfect and often misleading - like historians, biologists see through a glass darkly; and (b) There are not millions and millions of biologists working on every single biochemical and ecological problem, nor are scientists backed by infinite resources.

    Again, I am no biochemist. What I do know with more familiarity is that on an ecological, population genetics level evolutionary theory is an extremely persuasive and powerful tool for both prediction and explanation. On a population level, evolution fits sooo well...

    Of course, this does not really disprove what you are saying about God being involved at a biochemical level. I suppose that the intelligent design argument does acknowledge the larger population level evolutionary processes (I certainly hope so). But I cannot see how taking individual problems of biology that have not been comprehensively investigated and saying that these 'prove' that there was theistic intervention in the development of life can be a final conclusion, or a final rejection of evolutionary theory.

    So much remains uninvestigated, unproven and unknown. Intelligent design is based on too many assumptions that rely on the certainty of ambiguous and unknowable evidence.

    So what is the difference between believing in a God-of-the-gaps and evolution-of-the-gaps? We have reached a strange point in the argument if we are appealing to an intermediate biochemical pathway that we cannot even imagine.

    Absolutely agreed. I have been arguing that these software algorithms are built on a metaphor derived from one biological hypothesis. It is a mistake to push the metaphor too far. It is also a mistake to say that, just because the software works well and produces optimised antenna designs efficiently, actual historical biological processes must have followed the same route.

    As Ken pointed out earlier on the thread, natural selection can be modelled very simply. One genetic variation outbreeds other genetic variations, and becomes dominant in a population. In principle we simply count the relative number of grandchildren.

    “Fitness” in this understanding is a numerical criterion, which can be modelled as a simple binary parameter for the parent generation: “yes” (better than average breeding success) versus “no” (not better than average breeding success). All the myriad environmental influences in the natural world boil down to this one parameter. All theoretical eggs are in the one basket. “Natural selection” alone is credited with a huge amount of creative power.

    In NASA’s evolutionary algorithm, I think it highly unlikely that the state of optimisation of an antenna design can be represented in such a simple binary fashion as “yes” or “no”. The selection criteria are likely to be far more sophisticated than a single binary parameter.

    In mathematical terms, the evolutionary algorithm has been formulated so that the process is continually driven forward in some predetermined way to a point of convergence. By design the software will not allow the process to oscillate about a mean (stability), or degenerate into chaos (divergence).

    No, the Krebs cycle occurs in all eukaryotes (i.e. pretty much everything except bacteria). And it's hard to see how it could have evolved 'in the context of an already sophisticated system' because the sophisticated system probably couldn't have evolved without it; the Krebs cycle is not an optional extra refinement, it an 'absence = dead'.

    It's a model of selection, not evolution as a whole, showing the difference between cumulative and single-step selection (an important point for the IDers). Read it in context! (something that seems to be an issue for many creationists).

    I chose to focus my reply on one part of your post linked to Cheesy’s comments. But I will comment on another part of it now:
    quote:
    The people who build the software consciously model that software on Darwinian evolution, so your claim that it is not so modelled is prima face false.
    I don’t think I’ve made this claim at all. The developers of evolutionary algorithms undoubtedly took their inspirational ideas from Darwinism, but NASA probably had to modify them somewhat to be applicable to antenna design. See my comment above on NASA’s selection criteria.
    quote:
    By your logic, as soon as you model a thing you're proving that the thing is of intelligent origin. That is prima face absurd.

    Again, you’re misreading me. The key element in any computer simulation is how authentically it reflects the true physical processes, whether in the behaviour of antennas or in the biological world. In their software NASA can define the behaviour of their antennas with a certain numerical precision. The environment which is responsible for natural selection cannot easily be so defined.

    Serious question - has anyone produced a numerical model of the natural environment? It strikes me as an exceptionally difficult task due to the large number of random variables involved.
    quote:
    Of course they use their intelligence and a sense of purpose in building a model, that's what building models (and intelligence) is all about. How else would you do it? But it is a model - and the thing that is modelled does not automatically acquire the attributes of its modellers. (It is hard indeed to conceive of the world where this would be the case: you appear to be drifting into sympathetic magic and voodoo, rather than engineering.)

    No, you misunderstand me completely. I’m asking for the biologists’ computer models to truly reflect what is being claimed for the theoretical side of Darwinian evolution. From what I know about natural selection, I also want the computer models to reflect observational reality. Finch beaks in the Galapagos have been observed to cycle, rather than to grow ever longer. The models need to incorporate this possibility.

    Dawkins is more outspoken than most in flatly rejecting any metaphysics in his presentation of the theory. For him nature is unintelligent, undirected and described completely by the laws of science. His biomorphs are great fun, but he needs to build his computer models with much more care if he wants to claim the high scientific ground without an inadvertent concession to metaphysics at the same time.

    True enough, the natural environment is a very complex situation that would take an awful lot of effort to even begin to approximate in a simulation (even limiting things to the subset of the environment that is the climate is a really substantial problem. In addition to it being very complex to merely describe, it is also dynamic and will change in response to changes in the organisms that live there. Such feedback would make such a model, even for a simplified situation, very difficult - but would account for such things as the cycling of beak lengths of finches as what may be the best solution for succesful reproduction now may be less favourable in a few hundred years.

    This leads to the strong Anthropic Principle (I recommend a Google search here) which essentially is a meta-physical non-falsifiable claim that the Universe exists to bring forth life and intelligence.

    My own personal belief is in just that, a careful adjustment of the initial conditions to produce a "friendly" universe. A summary of the macro-scale life-friendly design is

    On the website to which Henry Troup linked above, I came across a reference to Haldane’s Dilemma, named after the evolutionary geneticist JBS Haldane. I had never heard of it. This is how the website summarises it:
    quote:
    Haldane's Dilemma is glaringly plain. Take the population we discussed above. In ten million years, it could substitute 1,667 beneficial nucleotides. That is less than 50 millionths of one percent of the genome. (And that is *before* we make deductions. For example, Gould says species typically spend *at least* 90% of their time in stasis, where little or no evolution occurs. There are other deductions we'll discuss later, but together they reduce the figure far below 1,667.) Is that enough to explain the origin of upright posture, speech, language, and appreciation of music, to name just a few of our uniquely human capacities? Is 1,667 beneficial nucleotides enough to make a sapien out of a simian?

    So, has anyone ever heard of Haldane’s Dilemma? Have any new solutions to the dilemma been proposed? Does the website present it correctly? Is it a “major scandal”?

    The abstract of which reads:

    The evolutionary origin of the Krebs citric acid cycle has been for a long time a model case in the understanding of the origin and evolution of metabolic pathways: How can the emergence of such a complex pathway be explained? A number of speculative studies have been carried out that have reached the conclusion that the Krebs cycle evolved from pathways for amino acid biosynthesis, but many important questions remain open: Why and how did the full pathway emerge from there? Are other alternative routes for the same purpose possible? Are they better or worse? Have they had any opportunity to be developed in cellular metabolism evolution? We have analyzed the Krebs cycle as a problem of chemical design to oxidize acetate yielding reduction equivalents to the respiratory chain to make ATP. Our analysis demonstrates that although there are several different chemical solutions to this problem, the design of this metabolic pathway as it occurs in living cells is the best chemical solution: It has the least possible number of steps and it also has the greatest ATP yielding. Study of the evolutionary possibilities of each one-taking the available material to build new pathways-demonstrates that the emergence of the Krebs cycle has been a typical case of opportunism in molecular evolution. Our analysis proves, therefore, that the role of opportunism in evolution has converted a problem of several possible chemical solutions into a single-solution problem, with the actual Krebs cycle demonstrated to be the best possible chemical design. Our results also allow us to derive the rules under which metabolic pathways emerged during the origin of life.

    Serfina, I am sorry that I represented what you are saying imperfectly; I have spent too many hours with people who would deny the epistemological foundations of that which I spent some long (sometimes unpleasant) hours studying. Thus I was prejudiced in my regard for what you were saying. Again, I apologise. My misconception about the Krebs cycle originated from the knowledge that 1080 poison, used in NZ against mammalian pests, affects only mammals and acts on the cycle. It must be specific to some mammalian aspect of the cycle rather than to the cycle itself as I assumed.

    Saying 'pretty much everything except bacteria' (and, I would add, archaea) is misleading in that bacteria 'rule' the living world in terms of diversity, numbers and (possibly) biomass. Simplicity seems to work well in the natural world. But that is not really entirely relevant to what we are talking about.

    Evolution as a self-sustaining process was mooted under a framework that sought validation from the big processes, the things that I know more about in ecology etc. From that point, scientists have focused more on smaller-scale things as the technologies for investigating biochemistry, molecular genetics etc. have improved. Evolution has been validated on a macro level, but there just is not enough technology or a sufficient resolution of investigation to explain every biochemical pathway - yet anyway. Glenn Oldham has pointed to one attempt at fitting the Krebs cycle within an evolutionary framework. I do not doubt that this research is highly speculative - I doubt that it is entirely persuasive.

    My problem with notions of biochemical irreducible complexity is that they attack the area where we know the least about what really goes on, where things are most complex and impenetrable. While I have chosen a different eventual course of study other than biology, and thus am not so immersed in biology or passionate about the subject to be anything near an expert, my experience of studying it indicates that on a macro-level, where things can be easily modelled and understood, evolution fits well. So the cynic within me speculates that those like Behe who assail some aspects of evolutionary theory from a biochemical level find a wealth of material there precisely because we really don't know all that much about what goes on, and the incredible complexity of these systems defies easy interpretation or analysis.

    Not at all. Its just one of many metabolic pathways available to bacxteria, many of which get on quite well without it. Almost certainly evolved by shunting together two ends of a degradative heterotrophic pathway. It's easy to think up Just So Stories to explain it, though hard to find any evidence fro which of them might be true.

    And there are plenty of circumstances under which parts of it would be useful. There is no "irreducible complexity" there at all.

    It's slightly harder to think up explanations for the electron-transfer pathways of photosynthesis... but I bet it could be done.

    No its not. It comes out in the wash. Its based on silly ideas of "mutation load" and "selection load" which are hangovers from pre-Darwininian essentialist thinking and simply aren't a problem in real life.

    Here's some more on evolutionary algorithms as applied to electronic circuits:
    quote:
    In recent years, several research groups have demonstrated the potential for artificial evolution to design electronic circuits automatically. An evolutionary algorithm is implemented, usually as a computer program, which mimics some aspects of Darwinian evolution: small random variations (mutations) are repeatedly made to one or more candidate circuit designs. Natural selection is replaced by a fitness measure of the degree to which a circuit meets the target engineering specification of behavior, size, power-consumption, and so on. Mutations resulting in a poorer fitness measurement are rejected, whereas those producing an improvement (or at least no deterioration) are allowed to persist and be built upon by further rounds of variation and selection. Commencing with either randomly generated circuit designs, results of previous evolutionary experiments, or an initial hand-designed attempt, repeated cycles of automated evolution can eventually produce circuits which satisfy the specification. Many elaborations to this basic scheme exist, such as allowing recombination of features from two or more individuals in an evolving population of variants.
    The whole article is rather technical, but I can recommend the discussion about half way down the page on the relative merits of constrained evolution versus unconstrained evolution.

    There are very many features of the natural world for which the best explanation, by far, is descent with modification from a common ancestor. I am not aware of the Intelligent Design movement having anything that is positive and detailed to put in the place of that explanation. All I am aware of being offered is vague words about design. But that simply leaves unexplained huge amounts of detail that Darwinian evolution copes with superbly.

    The kinds of features that do not sit at all well with intelligent design can be picked out by questions like these:

    Why is that “the hand of a man, formed for grasping, that of a mole for digging, …, the paddle of the porpoise, and the wing of the bat, should all be constructed on the same pattern, and should include similar bones, in the same relative positions? “

    Why is it that “the hind-feet of the kangaroo, which are so well fitted for bounding over the open plains, those of the climbing, leaf-eating koala, equally well fitted for grasping the branches of trees,- those of the ground-dwelling, insect or root-eating, bandicoots,- and those of some other Australian marsupials,- should all be constructed on the same extraordinary type, namely with the bones of the second and third digits extremely slender and enveloped within the same skin, so that they appear like a single toe furnished with two claws. Notwithstanding this similarity of pattern, it is obvious that the hind feet of these several animals are used for as widely different purposes as it is possible to conceive.”

    Why is the designer so fond of the pentadactyl limb even keeping the bones for two separate fingers when they are joined in the same digit? The pentadactyl limb surely cannot be the best design for all these uses. Nelson and Wells comment that “the suboptimality of the pentadactyl limb pattern has never been empirically demonstrated” - a comment that beggars belief. Apparently the pentadactyl limb is the best design for every one of these uses. It clearly is not in the case of the horse, which has but one toe, – but then why does the horse possess the vestiges of the ones it does not use?

    Why is it that “the immensely long spiral proboscis of a sphinxmoth, the curious folded one of a bee or bug, and the great jaws of a beetle?- yet all these organs, serving for such widely different purposes, are formed by infinitely numerous modifications of an upper lip, mandibles, and two pairs of maxillae. The same law governs the construction of the mouths and limbs of crustaceans. So it is with the flowers of plants. “

    “Why should one crustacean, which has an extremely complex mouth formed of many parts, consequently always have fewer legs; or conversely, those with many legs have simpler mouths? “ i.e. it seems clear that the missing legs have been used for the construction of the additional mouth parts. Does the designer have some hang up about giving crustaceans more complex mouths so he penalises them for it by reducing the number of legs?

    “Why should the sepals, petals, stamens, and pistils, in each flower, though fitted for such distinct purposes, be all constructed on the same pattern?”

    How do we explain the fact of “the presence of teeth in foetal whales, which when grown up have not a tooth in their heads; or the teeth, which never cut through the gums, in the upper jaws of unborn calves?” Anteaters have teeth as foetuses which they lose before birth and have no teeth thereafter – how is that a case of design?

    “How … can we explain these several facts in embryology,- namely, …
    - the various parts in the same individual embryo, which ultimately become very unlike and serve for diverse purposes, being at an early period of growth alike;
    - the common, but not invariable, resemblance between the embryos or larvae of the most distinct species in the same class;
    - the embryo often retaining, whilst within the egg or womb, structures which are of no service to it, either at that or at a later period of life; …?”

    Why do some beetles have wings which are “mere rudiments of membrane, which not rarely lie under wing-covers firmly soldered together” and are thus unusable?

    Why do “rudimentary organs sometimes retain their potentiality: … thus the tadpole of the common salamander or water-newt, as Mr. G. H. Lewes remarks, "has gills, and passes its existence in the water; but the Salamandra atra, which lives high up among the mountains, brings forth its young full-formed. This animal never lives in the water. Yet if we open a gravid female, we find tadpoles inside her with exquisitely feathered gills; and when placed in water they swim about like the tadpoles of the water-newt. Obviously this aquatic organisation has no reference to the future life of the animal, nor has it any adaptation to its embryonic condition; it has solely reference to ancestral adaptations, it repeats a phase in the development of its progenitors." “

    Why is it that “the boa constrictor has rudiments of hind-limbs and of a pelvis, and if it be said that these bones have been retained "to complete the scheme of nature," why, as Professor Weismann asks, have they not been retained by other snakes, which do not possess even a vestige of these same bones? “

    Why is the designer so found of making the larygeal nerve go around a structure near the heart that he does it in all vertebrates including even the giraffe where his penchant for this feature makes the nerve go all the way down the neck and all the way back up again making it 5 metres longer than it needs to be?

    All of these features fit superbly with evolution by descent with modification from common ancestors. Pre-existing structures are modified in different ways (or fall into disuse) whilst often retaining a marked resemblance with what went before. None of these questions suggest intelligent design as an answer.

    And I haven’t even got on to how Darwin explains the geographical distribution of species just as elegantly. And to add to all that we have more and more molecular information that matches the idea of evolution by descent with modification.

    Anti-darwinists often come up with absurd arguments about randomness in relation to natural selection. Darwinians then offer analogies that are simply trying to show that random variation followed by non-random selection results in the accumulation of useful information, hence the process of natural selection is not random. But all such analogies suffer the same fate in the hands of anti-darwinians: they hunt out every way in which the analogy does not match the details of natural selection and they completely miss the point about randomness plus selection equals non randomness. Dawkins useful Weasel analogy suffers the same fate and is turned by them into something he had no intention of it being: i.e a detailed model of all aspects of natural selection.

    Well it's a theory, and, of course since God can do anything and we can't be absolutely sure what he will and will not choose to do there are umpteen zillion possible theories. But the key point is, I think that the idea of common descent is inescapable. Why do alll mammals have 7 neck vertebrae regardless of the use the animal makes of it (rigid like many whales or bendier of twistable in others or very long in giraffes)? The fact that there are 7 cannot be related to design in every case. Why are whales genetically closer to hippos than to other mammals? If God did provide some necessary extra information to evolve the whale from something earlier (crossing the boundary in your terms) we still have the whale still inherits features from that earlier form and so Darwins is right about descent with modification. Is this what Intelligent Designers believe? Who knows? If they don't have at least some commonn descent in they are faced with a large body of similarities which they cannot make sense of.

    Under Darwinian evolution the only constraints (i.e. the boundary conditions) are:

    1) a self-replicating life-form and
    2) natural selection of those mutations that provide a breeding advantage.

    In Darwinian evolutionary theory for life-forms there is no possibility of changing these constraints – they are the only ones that the theory allows (for simplicity leaving behind the whole issue of genetic drift referred to above).

    However, since evolutionary algorithms are only sophisticated numerical models, they have more flexibility in how they model starting conditions and selection constraints. The choice is between a more constrained process (simply called “constrained”) and a less constrained process (called “unconstrained”).

    A constrained evolution attempts to keep designs within previously known parameters that have been found to work. In other words the numerical iteration process is unlikely to throw up any real surprises. The trial designs may be quite conventional, and the evolutionary process simply optimises standard technical approaches to the problem. So it’s a safe and reliable process, although somewhat unimaginative.

    With unconstrained evolution, the software is programmed to operate “well outside the box”. The initial trial designs may be very unconventional, and bear little or no relation to earlier technical approaches. By exploring many previously unexplored solutions, the algorithm may evolve a feasible designs that is genuinely novel. On the other hand, it may generate an impractical design that is unbuildable, or simply fail to converge at all. So there is more risk in the unconstrained approach.

    Such thinking may be very relevant to complex electronic micro-circuits, but since this is outside my own specialist field, I can’t really comment in detail any further. The overall point was that evolutionary algorithms have the freedom to vary the evolutionary process through different starting points and subsequent selection criteria.

    Neil, I am still not clear what point you are making in your posts on this nor whether your last post means that you see these algorithims as analogous to natural selection or not.

    However, it is important to note that it is potentially misleading to say that "the only constraints" for darwinian evolution are "1) a self-replicating life-form and 2) natural selection of those mutations that provide a breeding advantage." This is because selection occurs by means of a whole range of actual and particular constraints such a food supply, competition with other organisms, parasites, sexual competition, environmental conditions, and so on and so forth. These will vary from species to species and may also vary over time. The reproductive success of organisms will tend to depend on how well adapted they are to deal with these constraints. It is these constraints that are paralleled by the selection for better antennae in the antenna design program.

    The other set of constraints operating are the ways in which the laws of physics and chemistry limit the ways in which variation can arise. This parallels the way the antenna program has limits on how the next generation of antennae are produced by alterations to the previous generation.

    I think Rex has said much of this already. Forgive me if its already clear to you.

    Not to forget that different populations of the same species in different geographical locations will experience slightly different constraints that, given some form of isolation between the populations, could result in one population developing slightly differently to the other leading to potential differentiation of the populations into distinct species.

    The short answer is that I do see these algorithms as reflecting some features of Darwinian evolution, but as I understand it they are not directly analogous to natural selection, especially the unconstrained algorithms.

    I agree with you that natural selection is made up of a myriad of influences all operating simultaneously. However, unless I have misunderstood, it all boils down to one simple point: natural selection of a favourable mutation must mean more grandchildren in relative terms.

    One of the big differences between evolutionary algorithms for antennas and Darwinian evolution is that the former can specify in a simple deterministic fashion the various selection constraints. In antenna design we can write deterministic equations and set limits for size, weight, material content, frequency range, energy required etc. Within these limits we know from prior experience that an optimised design can be determined and constructed.

    I think it would be very difficult to model numerically the actual selection constraints on a living organism, such as “a food supply, competition with other organisms, parasites, sexual competition, environmental conditions, and so on and so forth”. If this can be done numerically at all, I suspect it would have to be based on some kind of probabilistic approach rather than a deterministic one.

    There are plenty of places in engineering where a probabilistic approach is used, such as in the calculation of wave loading or turbulent wind loading, but in these cases we can make measurements first and determine the statistical parameters needed by a probabilistic approach.

    How one would obtain similarly accurate data in biology I have no idea. Hence the whole complex process of natural selection is actually simplified dramatically by the Darwinian theory to a binary state – either the mutation outbreeds the competition and flourishes, or it doesn’t.

    The unconstrained evolutionary algorithm that I described earlier allows us to start with a far-from-optimised design that may be barely functional, or even non-functional. Iterations may also pass through non-functional states in the search to find a fully optimised design. Since a string of numbers never actually “dies”, the computer can carry on with the iteration in the hope of finding some parametric combination that is “alive” – i.e. technically functional and fully optimised.

    In the biological world this would be equivalent to a dead initial life-form or to evolutionary changes leading into extinction, something that cannot be permitted at all for a successful species. So the unconstrained evolutionary algorithm departs completely from biological reality at this point – but it may still generate novel and highly optimised antenna designs or whatever.

    To my mind Darwinism is more akin to the constrained evolutionary algorithm. An evolving life-form must acquire beneficial mutations in the population and remain functional at all times. This suggests that a more accurate model of the biological process is a highly constrained numerical algorithm, nearly optimised and functional at all stages of the iterative process.

    I suspect that a more constrained algorithm is always going to be much less inventive than a less constrained one – i.e. a constrained algorithm may generate improvements on existing designs, but it won’t generate wholly new designs that haven’t already been thought of. In biological terms we may generate new varieties and even the occasional sub-species, but no more than that.

    Speaking more generally, I don’t deny that up to a point natural selection in biology is an observed fact. However, in Darwinian evolution it is the only selection constraint allowed to operate, and is held responsible for all physiological and biochemical changes as micro-organisms evolved into mankind. Under natural selection there is assumed to be no limit on the amount of evolution that can take place. I think it remains to be demonstrated that natural selection alone has this creative power.

    Hope you don't mind me putting in my thoughts, and if I say anything too stoopid tell me to clear off.

In biological terms we may generate new varieties and even the occasional sub-species, but no more than that.

    Remember, we are looking back with 20/20 hindsight (well, more like 5/5 hindsight considering the fossil record).

    Imagine going back to when mammal-like reptiles were alive. The very first mammal would have just been another variety or sub-species at first. It is only now that we see that this sub-species radiated to the wide variety of mammals we see today.

    Each big change starts with a sub-species.

    Look at the things we consider 'new' in mammals such as fur, lactation, live bearing and in each case it can be seen to be just a modification of a reptilian feature.

    Speaking more generally, I don’t deny that up to a point natural selection in biology is an observed fact. However, in Darwinian evolution it is the only selection constraint allowed to operate, and is held responsible for all physiological and biochemical changes as micro-organisms evolved into mankind.

    Let us take the cell -> human very quickly.

    First multicelled - just a variation.
    Then a simple notochord - just a variation
    Then cartilidge (sp?)- just a variation
    Then a backbone - just a variaton
    Then jaws - just a variation
    Then bones - just a variation
    Then limbs - just a variation
    Then lungs - just a variation

    Of course the best example of this is the mammalian ear.
    The first jawed fishes used the first gill arch of the embryo of the jawless fish and adapted it into a jaw.
    Reptiles still use the same gill arch to form the jaw.
    Mammals developed their three boned ears from the jaw of reptiles. Our ears develoop from the first gill arch!

    The rest is history, but it is easy to see that taking things in context and not jumping steps then each species is more "advanced" and will be able to survive in its environment and yet has what look superficially like new organs.

    But on what grounds do you say that? That is very puzzling. The continual gradual modification of existing structures will produce new structures that may eventually be so altered that they are so different from their original structure that the original is uninferable from them.

    And even so - and this relates to my post about homologies - look around at the natural world and we see hundreds and thousands of similarities in structure that suggest the alteration of one to the other in ways that go well beyond the species level. All mammals with 7 neck vertebrae, crustaceans with complicated mouths always having fewer legs; whales having no back legs but having a pelvis nevertheless; the tube from the lungs of the whale passing underneath and in front of the brain (as it does in all mammals) rather than going straight up to the top of the head by going above and behind it which would be a good design option). All of these look like the product of an evolutionary process that has indeed been constrained by the requirement that existing structures are altered. And they all extend well beyond the species level. Add the fossil record to this and one has yet more evidence.

    "Similarity in design means evolution occurred."

    Is that correct?

    My house is of similar design to my neighbour's. However, mine has one more bedroom and a den. Does that mean mine evolved from his (since the extra rooms make it a "better" house)? That his evolved from mine (as the other bedroom and den were no longer required)? Or, that they have a common house as an ancestor? Perhas they have the same designer?

    Sharkshooter, there is something called 'convergent evolution'. According to this idea, you will end up with similar features evolving in unrelated organisms who are adaprting to similar environmental conditions. Thus you have a dolphin-like shape evolving in the icthyosaurs (marine reptiles contemporaneous with the dinosaurs) millions of years before the actual cetaceans (whales and dolphins) evolve. The marine mammals evolve to fill the ecological niche(s) left 'vacant' by the mass extinction of sea reptiles etc. at the end of the Cretaceous period.

    It also explains why the marsupial Thylacine evolved a wolf-like shape as it was (until its 20th century extinction) a predator in the same 'niche' as the unrelated placental mammals of Eurasia and North America. (Australasia having no placentals till humans introduced the dog (dingo) a few thousand years ago.)

    This supports your "convergent evolution" (I'll take that as a given) as well as a Creator who understood what different species of His creation needed for these environments.

    Would it have been necessary for God to have created each species completely different for people to believe that He created them? So, for example, no two species with the same number of vertebrae, no two species with the same number or design of eyes, no two species with the same basic limb design, etc.

    No, the point was more that the same basic feature occurs even though it has no real reason to be the same.

    So, in your house analogy, it could be something like an "ancestral house" having a fireplace then subsequent houses maintain that feature even though in many of them the fire becomes a couple of electric bars and there is no chimney, and that the introduction of central heating has made it superfluous anyway.

    <snip>

    This is where I wish I could see the various equations lying behind the selection constraints in these evolutionary algorithms. Since neither antenna design nor electronic micro-circuits are my technical speciality, I can only talk in mathematical generalities at the moment.

    I based my previous comments on the limitations of constrained evolution on deductions from the webpage comments on evolutionary algorithms in relation to electronic micro-circuits. It does seem intuitively obvious to me that, in a complex iterative process trying to optimise the parameters of a multi-dimensional problem, the mathematics of the selection constraints can be varied at the discretion of the programmer, and that this will have an enormous influence on the result.

    A very loose set of selection constraints may mean that the software never converges to anything specific, or oscillates about a mean, or even becomes unstable. On the other hand, a very tight set of constraints may produce little or no improvement on existing (non-evolutionary) designs.

    I have occasionally used some technical graphing software to produce contour graphs, and this gives me the choice of various algorithms for producing contours. There have been some cases where one algorithm gave me sensible results, and another gave me garbage. Plenty of things can go wrong in large scale numerical manipulation.

    To sum up, I think the direct analogy between evolutionary algorithms and biological evolution breaks down at the point of the programmed selection constraints. Natural selection in biology is probably too complex a phenomenon to be modelled accurately at present.

    I haven’t forgotten your homology post – I’m still thinking about it. [Smile]

    No, it is not necessary, God could create how he wanted, but evolution can't. Evolution is severely constrained.

    It is in the detail that the differences become apparent. Let us take for an example birds and bats. Both fly and so both have wings.

    The wings are different and yet look superficially the same because of convergent evolution. Bats cannot have feathers because they are not birds, and birds cannot feed their chicks with milk because they are not mammals.
    And yet, both of these have backbones.

    There is a strict heirachy of living things and creatures cannot pick and choose what they have. If they were all designed seperately, then any design could work, and a nested hierachy is not necessary, you could take the best bits of each and put them together. Evolution demands a strict hierachy.

    Of course, this in itself is not evidence one way or the other. To understand why evolution is the way life developed, all the other evidence needs to be considered, but just the fact that life does fall into a nested hierachy with no exceptions supports evolution in a very important way.

    I haven't explained this very well at all, sorry.

    This is the part with which I disagree. I think the following is as reasonable a statement:

    quote:
    The wings are different and yet look superficially the same because they were created for different species but the same purpose.
    Either statement works - so it does not support evolution.

    Sharkshooter,

    I understand what you mean. If that was the only consideration then you would have a point.

    We can see that a bat is a mammal and that a bird is, well, a bird. This is from the physiology.

    We can see from the fossil evidence that birds evolved from reptiles, probably dinosaurs.

    We can see that mammals evolved from reptiles, too, but a lot earlier.

    We can examine the embryology and see that bothe birds and mammals are related to reptiles, but that the embryos show fundamental differences that highlight the different evolutionary pathways (especially based on the circulation system).

    We can examine the genetics and see the way that birds and mammals are related to reptiles is exactly what we would expect if evolution had evolved them in exactly the way that the fossil record / embryology and physysiology would expect.

    Each of these is evidence for evolution, but none of them are enough on their own. Together, it becomes clear that birds and bats evolved, they were not seperately created in isolation from reptiles.

    That certainly seemed to be Glenn Oldham's point.

    No, the point was more that the same basic feature occurs even though it has no real reason to be the same.

    So, in your house analogy, it could be something like an "ancestral house" having a fireplace then subsequent houses maintain that feature even though in many of them the fire becomes a couple of electric bars and there is no chimney, and that the introduction of central heating has made it superfluous anyway.

    Yes, that is indeed the point. I am sorry if that has not been clear from my postings. The kinds of similarities I have been pointing to are those which have no apparent relation to function and are thus a challenge to the view that they are explainable by reference to design.

    There is no design reason why the whale needs seven vertebrae in its neck which is very short and rigid and would be just as good with fewer. There is no known functional reason why the recurrent laryngeal nerve in, for example, mammals goes from the brain down past the larynx to near the heart, around the ductus arteriousus and then back up to the larynx. This is an unecessary detour in all mammals but a remarkably bizarre one in giraffes.

    These examples make sense from the point of view of evolution because these structures are seen as the result of modifying structures inherited from ancestors way back in time (where the structures were functional, or were not suboptimal in the way that they have become).

    Not at all. But whatever created all living things has arranged things so that there is no species with a feature that could not easily - and in almost all cases obviously -- have evolved from an earlier feature, even when an alternate arrangement would be obviously advantageous.

    It's not a case of a creator god having to design all land vertebrates (say) with different basic limb designs: it's a case of there being no land vertebrates with different basic limb designs. Newt, bat, snake, whale and man are obviously fellows.

    There is no species of eight-legged mouse. Were there to be one, and were it clearly impossible for its skeletal structure to have evolved from the common mammalian ancestor, then that would be a clear indication that evolution as we understand it is wrong.

    Yet even where there are gross differences in basic design - say between the invertebrates and the vertebrates - there is genetic evidence pointing back to a common (and very distant) ancestor.

    If you believe in a creator god, then all the evidence is that the act of creation is through evolution.

Rather than computer modelling it there have been many direct experiments to demonstrate it, from work on showing how bacteria can acquire enzymic activity they did not previously have, through to alteration in fish sizes as a result of predation and many more.

    There is an argument put forward by some intelligent design advocates that says that selection operating on random variation cannot produce novelty. The point about the evolutionary algorithms is that they demonstrate that it can. So: Rest-In-Peace one argument against evolution by natural selection.

    You may still want to maintain that evolution from common descent by natural selection has NOT given us the biological diversity that we have today, but in that case you will have to target some other element of the theory.

    The common body pattern of four limbs is not, as sharkshooter says, evidence of anything. It is, however, a phenomenon that needs to be accounted for in any theory of how things came to be as they are. Evolution has a simple answer, conforming to Ockham's famous heuristic.

    Any form of creationism, including Intelligent Design, pretty much has to account for why the common plan is used when something else would make more sense. This occurs, IMO, at both micro- and macro- levels. Human sinuses are a small but annoying example. Residual flippers in whales and the snake's pelvis are more macro level
    instances.

    Let's see the ID arguments other than "irreducible complexity." What makes you gasp and say "that was designed"?

    The point about the homologies is that they nest within groups.

    You can draw trees connecting particular characters of organisms (genetic, anatomical, metabolic, whatever).

    And you find that when one character is shared by many or most of one group of organisms, and not by another, then so are many other characters as well.

    So mammals are not just identifiable by milk, hair, 7 neck vertebrae and so on, but by hundreds of characters we share with each other, but not with any other organisms.

    And within mammals, a group like the primates will share some characters.

    Recently we've been finding large numbers of DNA sequences that are also shared.

    It it possible to connect these into trees as well. On a large scale These trees almost always show the same patterns of descent as anatomy does.

    Where the DNA evidence has changed our view of phylogenetics it nearly always supports hypotheses put forward by at least some taxonomists.

    And these are testable hypotheses. When a taxonomist puts two organisms into the same taxon [named group of organisms] and a third in a different one, they are making the hypothesis that those two organisms are more closely related to each other by common descent - that is real kinship, not just similarity.

    And that leads to testable hypotheses. When two organisms placed in once group by anatomy, and a third elsewhere, we can predict that they are also more closely related by gene sequence. And that incoludes so-called "junk" DNA. And (this is a good one) their parasites tend to be more closely related as well.

    Overwhelmingly often, these predictions are on the whole borne out. For example, gorillas and chimpanzees really do have gene sequences that are more similar to each other than to

    Sometimes the predictions are found to be false. For example chimps are clearly more closely related to humans than either are to gorillas - however most anatomists used to put chimps and gorillas in in once group, and ourselves in another.

    On the whole such readjustments have been small-scale, involving closely related and very similar organisms. There have been very few cases where an organism has been found to have been placed in the wrong large-scale taxon.

    What has happened more often is thatsequence evidence reinforces the hypothesis of one large group that was difficult to resolve using other characters. Relationships between the large groups - families, classes, phyla - are often easier to resolve with sequence evidence.

    I didn't say it was: it was an illustrative point showing, I hope, that you wouldn't need every creature designed differently to point to there being a creator. Just one would do, either alive or in the fossil record.

    We're missing that one.

    On the other hand, we have a great many creatures with features that look like bodge jobs from earlier versions, from the macro to the micro.

    Evolution accounts for both these observations, the idea of direct creation accounts for neither and would seem somewhat to contradict them.

    Your post on homology contained a lot of interesting information on animal anatomy and physiology which I will take as a given. The facts are not in dispute, rather it is the interpretation to be made of them. Homology was known about long before Darwin, but the similarities were seen as evidence of archetypes and the common hand of the Creator.

    The paragraph that I have selected above shows a common line of argument in writing about Darwinian evolution. It can be found in Darwin’s words (as quoted in your post) and in more recent times, Stephen J. Gould has made a similar argument with his comments about “highly inefficient” Pandas’ thumbs.

    They and many others make the same fundamental argument, but it should be noted that the argument is a mixture of science and theology. There are two distinct problems here.

    The first is a problem that you chose to gloss over: the empirical demonstration that a given biological anatomy is in fact suboptimal from a scientific perspective. It is asserted, but not demonstrated, that apparently homologous structures are less than perfect (or suboptimal). This presumes that we have access to what would be truly optimal, and can define “perfection” in scientific rather than aesthetic terms.

    In the light of what mechanical engineers can actually achieve in artificial anatomical forms, I think this is a very bold claim. I refer you to the list of events in the Robot Olympics to gauge our current level of anatomical engineering.

    I would argue that we simply don’t have the data on which to do a scientific comparison, except in a few rare circumstances. As my archetypally dour Scottish dentist once said to me, in connection with a tooth crown, “we’re a very poor second to the Almighty”. [Smile]

    The second problem is that the argument is clearly a theological one. God could not have done it this way, because it would be against what we understand God to be. And if by some chance he did work this way, he’d in any case do a far better job of it. Since this can’t be God’s work, then some other naturalistic mechanism must be found.

    At this point we have left the scientific realm far behind, and are well into theology and metaphysics, not to mention the logical fallacy of a false dichotomy.

    For a further development of this point, I refer to another article by Paul Nelson at the Access Research Network website. He explores in some depth the theological basis for some evolutionary arguments. Darwin used them frequently, ostensibly to protect the dignity of the Creator, but Darwin’s successors have used them to make the Creator redundant.

    You have mentioned several times the giraffe’s neck, and the fact that the laryngeal nerve (presumably the nerve that controls the larynx) travels all the way from the brain down to the near the heart and then back up the neck to the larynx. You opine that this nerve actually takes a very inefficient route, travelling many metres more than necessary, evidence not of an intelligence at work, but of descent with modification from a homologous structure in similar but short necked animals.

    A response from an intelligent design perspective would be to examine the engineering claim that this lengthy route for the nerve is in fact inefficient or sub-optimal. Your comment here presumes that optimality would mean the shortest travel distance, or at least, a significantly shorter one than at present, but this ignores all other design criteria apart from length. The onus is on you to demonstrate the inefficiency of the present arrangement, rather than to assert it.

    I would turn the question on its head. What benefits accrue to the giraffe from this apparently unusual nerve configuration? Sadly I don’t have the knowledge of animal anatomy or electrical micro-circuits to take this further. However, it does strike me as an interesting research exercise. It is certainly a further example that an intelligent design approach can stimulate scientific questions.

    And animals are not different. They are simply strings of DNA made flesh in a constrained environment.

    Constrained systems can come up with new solutions- one case comes to mind where there was an attempt to see how to make a tone detector using the lowest possible number of parts in an electric circuit- and it came up with a solution using fewer than the theoretical minimum number of parts- and a solution in which some of the necessary parts were not even part of the circuit- meaning that in some cases it was the physics of the individual cells that was affecting the circuit, not their properties as part of the circuit.

    How's that for creation of something new via a genetic algorithm?

    It's not just the homologies that are the question- a creator would probably use them too. It's the stupid homologies that are the problem. If God is responsible for e.g. the giraffe's nerve going five metres out of its way, then he's either lazy or stupid. See also: tonsils (and any other vestigial organ).

    Wrong. The argument for evolution is a scientific one. The one against creationism is a theological one as the creationists have brought God into the picture, and once God is there he needs to be dealt with. If the creationists would just give up and go away, the theological arguments would be lost- but because people keep bringing the subject up, it is considered necessary to protect against them.

    Either that or you can have a stupid God who does random things. I can't falsify that- but Occam's Razor tends to indicate against it. I also suspect you don't believe in a stupid God.

    At this point we have left the scientific realm far behind, and are well into theology and metaphysics, not to mention the logical fallacy of a false dichotomy.

    Anything can stimulate scientific questions- but if it's electrical impulses you want, there's the entire spinal cord round there. You could easily move another nerve that did have to go that way rather than waste 5m of nerve.

    Ah - I am now getting the picture. Since God didn't do it the way you (generic) would have, He obviously didn't do it at all. Perhaps if He was as smart as man is, He might done it your way, and then, perhaps you would believe that He could be the Creator.

    By the way, "waste" presumes use of materials of some sort, normally of limited supply. Creation from nothing implies an unlimited supply of materials. So, an extra 5m of nerve is irrelevant in creation.

    Perhaps instead of repeating it, you could explain it? I don't understand what you're saying.

    I think it boils down to you using a different definition of 'new' to the one I'm used to.

    Let me define what I mean by 'new': by 'new', I mean something that's different to what's gone before, something that's here when before it wasn't here, something with novelty, something that's changed from the previous state.

    With genetic algorithms this 'new' is created by randomising, and in living organisms this 'new' is created by mutation. In both cases, something appears that wasn't there before: this is a new thing.

    Are you saying that this new thing that is created by randomness isn't in fact new?

    What, then, do you mean by 'new'?

    Wrong on both counts. The duckbilled platypus wasn't done the way I'd do it- but that's not evidence that God didn't make that thing. There's doing something a way I wouldn't, which is no problem, and there's doing something a stupid way.

    Also the extra 5m of nerve may be irrelevant to God, but it's certainly relevant to the giraffe who has to grow the thing- or don't you believe you have to eat to get the energy? (Actually, I think the extra fingerbones in certain animals paws and wings are a better example than the nerve).

    What, then, do you mean by 'new'?

    R

    Fair enough, I think the word “new” is being used in various senses here, so I’ll try and clarify.

    Firstly, there is a sense in which the optimised design that emerges from the evolutionary algorithm can rightly be called new, since that particular combination of parameters has probably never seen the light of day before. The string of N parameters that defines the engineering problem began life as something less efficient, and the algorithm has mutated them into something more efficient. We therefore have a new set of numbers representing an optimised design. I’m not denying for a moment that this may be very useful information to the engineer.

    However – and this is the but – the algorithm cannot break away from the original N parameters and the programmed constraints to give us the answer to a problem with N+M parameters and a different set of constraints. The program begins with N parameters for a specific engineering problem, and finishes with N parameters – for that same problem. So in that sense nothing has changed. We simply have a more desirable set of numbers than we started with.

    I’ll try and illustrate further with a simple example.

    If you imagine a problem with 3 parameters for simplicity (i.e. N=3), then the parameters can be visualised as the x, y and z axes of a 3-dimensional graph. The constraints applied by the engineer will determine the applicable regions of each axis where an optimised solution may be found. For example, x may be constrained to lie between 10 and 1000, y must be greater than 0 but less than 50, and z greater than 500 but less than 10000. These limits define a search space.

    At each point within this search space, the engineer defines a fitness function which is related to the values x, y and z. For example, if x, y and z values relate to mass, then total mass m = x + y + z.. Other fitness functions (e.g. size) may also be applicable and likewise some function of x, y and z. For each point in the xyz search space, these individual fitness functions are then combined in a programmed fashion to give an overall fitness value.

    So at the start, even before the algorithm has begun “number crunching”, all fitness values in the xyz space have been defined in principle by the programmed fitness function(s) and all the other constraints. There is a sense in which the program knows in advance the fitness values for all possible x, y and z values. The only problem remaining is the exact x, y and z location(s) of maximum fitness within the permitted region.

    The xyz search space may be so large that it is unclear where to start. This is where the evolutionary algorithms come in, with randomised sets of start parameters that amount to a random scatter of points in the permitted xyz search space. Through the “breeding” process of recombination and mutation, the algorithm can generate further sets of parameters and search the space much more rapidly, always looking for the optimised point(s).

    It is important to note that the process is programmed to find the optimum. What is optimum is defined completely by the engineer. The algorithm is written on the presumption that an optimum exists and so goes looking for it until it finds it. The engineer has defined both the problem (where is the optimum?) and its solution (an efficient search algorithm). The numbers may be new, but the creativity belongs to the engineer. The algorithm is simply a creative tool in his or her hands.

    I hope that that’s a little clearer, but let me know if it’s not.

    Although it’s quite a complex paper, I can recommend the link provided by Justinian above to a further example of the application of evolutionary algorithms in electronic micro-circuits. This problem was defined by 1800 bits of information. I have printed this out to study it further and may come back with some further comments.

    So whats to stop you from regarding evolution by natural selection as exactly parallel to this with God as the engineer? In such a case God could be seen as having set up the parameters: the laws of physics and chemistry, and once self replicating entities get going then random variation plus selection by constraints in the environment results in the new configurations being found and succeeding better and then these in turn evolving. As they increase in complexity they impose new selection constraints on each other (predator prey relationships are just one example) and so it continues.

    There is nothing whatsoever in your account of the evolutionary algorithms so far that shows that natural selection is and incoherent idea, or that it has limits that would prevent it from generating the range of organisms we see today from a common ancestor.

    I'll get back to you on the homology matter, Neil, after I get a chance to read the 10,000 word paper by Nelson that you posted.

    I would, however, have liked a response to things like the fact that whales and anteaters as foetuses go through a stage where they have teeth. These are especially clear examples of sub-optimality that demand a coherent explanation from Intelligent Design theory. These kinds of facts seem to me to be simply incoherent without the concept of common descent.

    The 'who are we to say what God would do' argument is a tricky one for anti-evloutionists to use, since they clearly believe that they can say that God would not have used evolution as a method of creation.

    I think any discussion of apparent sub-opimality must take into account all stages of the animal's life. An anatomical feature which is puzzling in a mature specimen may be more explainable at a younger stage - and vice versa. To use another engineering example, the anatomical feature may be "temporary works", essential at a younger stage, but no longer critical for survival past maturity.

    Caterpillars turn into butterflies. Crabs must shed their skin - becoming temporarily very vulnerable - in order to grow bigger. Humans lose the teeth they are born with and grow another set. Our lungs were full of water whilst in the womb, but once born they must become full of air for survival.

    The natural world is indeed full of amazing feats and remarkable changes. What is the meaning of nascent teeth in whales and anteater foetuses? I'm not sure at present, but I'll think on. I'm going to be away from my computer for a long weekend, so I'll get back to this thread properly next week.

    2 things:

    1) sub-optimality isn't really important for the homology argument, its just a strong clue. The big deal is the way different characters nest in phylogenetic trees.

    And you can't seriously doubt that there are many sub-optimal characters in living things. Ever had gout? That's because you, and every other human (every other ape in fact) has a broken gene that codes for an enzyme to handle purines.

    2) Search space arguments neat to be taken with a pinch of salt. Physically inclined people tend to like them more than biologists do. But the numbers are so big its hard to get anywhere with them.
    The search space for an individual protein coded for by DNA is larger than the likely number of particles in the universe.

    In fact there are self-modifying genes and proteins in your immune system that have search spaces larger than the likely number of particles in the universe.

    Forgen mere astronomical numbers - biological numbers are BIG. That confuses physicists and philosophers who like to keep things simple. Biology isn't simple.

    Biological "laws" aren't like physical laws, still less like mathematical laws. They are hypotheses about the probability of outcomes, based on observation of actual phenomena. All is contingent. Everything is stochastic. Biology really is Natural History, not Natural Philosophy.

    [Hot and Hormonal] HUMBLE PIE ALERT [Hot and Hormonal]
    A CORRECTION AND AN APOLOGY
    I have on three separate occassions on this thread stated that all mammals have seven cervical vertebrae. This is not correct. Further enquiry on my part reveals that although the vast majority of mammal species (about 99.9% of them) have seven vertebrae, there are two orders of mammals that depart from this pattern: the order Edentata (edentates) which includes anteaters armadillos and sloths; and the order Sirenia ("sea cows," dugongs, and manatees).

    I apologise to shipmates for this error and mistatement.

    In terms of the overall argument, however, the great uniformity of the number of cervical vertebrae in the majority of mammal species still calls for an explanation. Bird and Reptiles vary considerably more in this aspect of their anatomy.

    So far Neil has posted links to three articles by Paul Nelson (two written with Jonathan Wells). They all relate to homologies and evolution by descent from a common ancestor. It is about time I said something about them. I’ll start with the last one first. It can all be found on the Access Research Network Jettison the Arguments, or the Rule? The Place of Darwinian Theological Themata in Evolutionary Reasoning;

    This 1998 article by Nelson is a revised version of one entitled “The Role of Theology in Current Evolutionary Reasoning” published in 1996 in the journal Biology & Philosophy and which has been included in the book Intelligent Design Creationism and Its Critics - Philosophical, Theological, and Scientific Perspectives Edited by Robert T. Pennock (2001) where it is immediately followed by an excellent critique of it by Kelly C. Smith entitled “Appealing to Ignorance Behind the Cloak of Ambiguity” to which, alas, I have been unable to find a link. ( Table of Contents .)

    Nelson’s article has two aims. One is to show that the arguments for evolution from homologies and imperfections in design do not rule out some forms of intelligent design theory. The other is to subvert the argument altogether by attacking what (mistakenly) he understands methodological naturalism to entail. I will just respond to his arguments against the argument from homologies and imperfections and leave the issue of methodological naturalism for the time being (it has been much discussed on this thread already).

    So, let us keep in mind that the challenge intelligent designers face is to explain features of the world such as these:
    - that in some species of whales and in anteaters the foetus develops teeth which they loose before they are born and never get to use, the adults having no teeth at all during their adult lives;
    - that there no known functional reason why the giraffe’s recurrent laryngeal nerve does not go direct to the larynx but travels 5 metres out of its way to near the heart and back up to the larynx; and
    - the vast majority of mammals have 7 neck vertebrae despite the fact that the necks of those mammals vary so greatly in their length and in the uses to which they are put.

    Nelson says that the argument for evolution from features like these (call each such feature ‘p’) goes something like this:

    quote:
    1. If p is an instance of organic design, then p was produced either by a wise creator, or by descent with modification (evolution).
    2. If p (an instance of organic design) was produced by a wise creator, then p should be perfect (or should exhibit no imperfections).
    3. Organic design p is not perfect (or exhibits imperfections).
    [therefore]
    [4] Organic design p was not produced by a wise creator, but by descent with modification. Some organic designs are evidence of evolution.

    Nelson offers a number of challenges to this argument.

    1) He says that ID theory allows the idea that the organs of some creatures may lose some of their functionality as a result of degeneration. This would explain blind cave animals still having eyes, and flightless birds and beetles still having wings. Well, broadly speaking, that is fair enough – it is what evolutionary theory predicts anyway.

    2) In the earlier version of the paper Nelson also mentioned some creationists who take the view that there has been microevolutionary change in the basic types that were originally created and that this could account for some homologies. (Oddly he excludes this from his later version of the paper). Again, fair enough, that is using part of evolutionary theory again anyway - inheritance from a common ancestor.

    He notes that the mechanisms in (1) and (2) can’t account for all the kinds of features raised by evolutionist arguments. He therefore offers more.

    3) God may not be the kind of God that the argument takes him to be. God might have limited power. (Nelson does not think so, so I am not sure how this helps him).

    4) God may be limited by the larger picture. That is to say, God may not be able to realise the goal of perfect organisms and still be able at the same time to achieve the perfection of a larger part (or the whole) of creation.

    quote:
    On this view, any judgment of perfection or imperfection must be qualified with a proviso that perfection -- defined as divinely created perfection -- can be judged only on the scale of the whole creation. And there is no reason for a creator to optimize one part of the universe at the expense of the whole.
    quote:
    the finitude of human scientific observation may lead us to infer mistakenly that an organic design (e.g., the panda's pseudothumb) is imperfect, when its imperfection is only apparent, that is, local.
    Now there is no doubt truth in this approach. It is the kind of view that that theistic evolutionists need to appeal to. But I do not think that it covers all the remaining examples. Might Nelson be able to tell us what part of the universe would have suffered if the giraffe’s laryngeal nerve was shorter, or if foetal whales and anteaters did not develop and lose the teeth that they never use as adults? Perhaps he would point to these comments of his:

    quote:
    The creator could have been limited in some way by unknown "compossibility" constraints. In crudest outline, a compossibility analysis would ask whether all possibilities are mutually consistent. … One may have failed to identify the correct reference situation by which to judge the design (perhaps by looking at too narrow a slice of … life history). The flippers of marine turtles, for example, strike us as rather badly designed for digging holes in beach sand to place eggs. The same flippers, however, perform efficiently in the water, where the turtles spend most of their time. Which reference situation takes precedence in an optimality analysis?
    This is an important point and one that evolutionists take into account is assessing adaptations. Is Nelson implying that foetal whales and anteaters somehow need to did develop and lose the teeth that they never use as adults because of unknown "compossibility" constraints? Why should we believe that? Evolutionary theory offers clear reasons for such constraints: the fact that evolution comes about as variation in existing systems and structures leads, through selection to their being adapted and modified often showing traces of what they were modified from. What does ID theory have to offer in the place of this? Who knows?

    5) When Nelson looks at the homology issue he offers two defences of the Intelligent Design option. The first is that he challenges the view that these common features (like the pentadactyl limb) are not the optimal designs.

    I have to confess that I still find this somewhat breathtaking. Let’s take the fact that the vast majority of mammals (see my immediately previous post) have seven cervical (neck) vertebrae. This applies to those with short rigid necks, long slender necks, medium sized necks, necks that support heads that rotate from side to side, necks that are attached to heads that don’t; necks of tall grazing animals that have to lower them to graze (horses, cows), necks of the big cats, necks of elephants, necks of those animals that butt each other in courtship contests, necks of bats, necks of moles, of giraffes. All of these have seven vertebrae. Paul Nelson is asking us to believe that in every single one of these cases seven is the optimal number. Not five or six or four, but seven. But despite biophysics being a rich field, as far as I am aware we know of no physical principle that would suggest that seven vertebrae would be optimal in these cases. We also know that birds sometimes occupying much the same ecological niches as mammals (on islands where mammals are absent for example) have necks with 9 to 25 vertebrae. Why are they so different from mammals in this respect?

    In short, the idea that in all these cases the number of the vertebrae is optimal seems unsupported. We may be wrong about this, but it is hard to see why. An evolutionary explanation for the pattern has been offered (see Why do Mammals have but seven cervical vertebrae?;

    6) The second defence is that he says that we can’t discount the possibility that the creator simply choose to repeat the same design in different species.

    Nelson is not clear how far he would press this one, but it is not clear that it would cover foetal teeth in whales and anteaters, or the giraffe’s laryngeal nerve. It is always logically possible, of course, that God’s aesthetic sense is so different from ours that it is for artistic reasons that these oddities are there. But we are moving into the realms of ‘who are we to say what God might do?’ As I have pointed out earlier, this question is hardly a help to those against evolution by natural selection, since it challenges all views equally. Who are we to say that God did NOT use evolution by natural selection to make the world?

    Conclusion
    In short Nelson’s argument comes to this: that the argument from imperfections and homologies does not rule out that there might be a version of Intelligent Design Theory that explains them. That version is not the one that Darwin was arguing against (the one he argued against was the one based on William Paley’s views).

    This is a logical and reasonable conclusion. But how likely is it that there is such a version of the Intelligent Design Theory? And if one exists, how likely is it that it is true, compared to how likely evolution by natural selection is true?

    A major problem facing ID at the present time is that it lacks any clear theory. The movement has been largely content to argue against evolution by natural selection, but has not offered any clear alternative.

    Did Nelson actually address the nature of homology and nested characters? Or just the idea of sub-optimal characters?

    Indeed so. As I said in my post ‘Evolutionary theory offers clear reasons for such constraints: the fact that evolution comes about as variation in existing systems and structures leads, through selection to their being adapted and modified often showing traces of what they were modified from. What does ID theory have to offer in the place of this?’

    No, not really, and that is a great failing. He seems to have three lines of approach on this issue. The two I mentioned
    - he challenges the idea that they are sub-optimal;
    - he says that God might have just chosen to do it that way (which could be extended to cover the nested nature of the homologies); and
    - in his other two articles he basically says: prove that the homologies are a result of common descent, show us the mechanism, be it genetic, developmental, etc. that is supposed to cause these features.

    Homology: A Concept in Crisis; and

    Is Common Descent an Axiom of Biology.

    I have a response to that issue in hand.

    Note that the bold comment above is clearly a theological one. It is based on a clear understanding of what the creator cannot do. That in turn has to be based on some conception of what the creator is and how he will act. The content of this comment may or may not be justified, but the argument in this comment is not in the least bit scientific.

    I’ve now been able to study in more detail Justinian’s example of the use of evolutionary algorithms. The problem concerned evolving a very specific functionality to a small portion of a “Programmable Field Gate Array (PFGA)”, which I presume is some kind of electronic microchip.

    The functionality required was to differentiate clearly between a 1KHz and a 10kHz square wave input signal. A 1KHz signal should generate a constant output of +5 volts, whereas a 10kHz signal should generate 0 volts. The chip had no access to any kind of timing clock or reference frequency and had to reply on its internal dynamic properties alone to make the differentiation. In other words, the chip had to be configured to act as a simple tone distinguisher.

    The chip was connected directly to a computer, and could be modified and controlled from within the computer by a sequence of numerical parameters, amounting to 1800 bits of information. The computer also controlled the input signals and monitored the output signals of the chip.

    The performance of the chip under each configuration was therefore not simply modelled by a set of theoretical equations, but was measured in real time, taking into account all the properties of the chip. This probably simplified enormously the engineers’ task and also enabled the experiment to be more realistic as a result.

    Even with this simplification the scale of the engineers’ search task can be demonstrated numerically. A basic equation in information theory is that the information content of a configuration I (in bits) is related to its probability of occurrence p (between 0 and 1) as follows:
    quote:
    I = logarithm to the base 2 of (1/p), or rearranging gives: p = 1/(2 to the power I)
    For 1800 bits of information, this equation gives us a probability of 10 to the power of minus 542 – i.e. there is a huge number of potential configurations, with an infinitesimally small probability of achieving a successful configuration by a random guess. Hence the desirability of an efficient targeted search pattern, such as the evolutionary algorithm.

    Note the following comments in the paper on the chip configuration:
    quote:
    No configuration of the cells can cause the device to be damaged -- it is impossible to connect two outputs together, for instance, because all internal connections are uni-directional. So an evolutionary algorithm can be allowed to manipulate the configuration of the real chip without the need for legality constraints or checking.

    In other words, there is no such thing as a highly deleterious mutation. Considered as an animal analogue the chip configuration is essentially unkillable, despite any genetic defects, in contrast to the natural world. The “population” size of 50 remains constant regardless of any mutations, good or bad.

    The population size was set at 50 “creatures” (i.e. strings of numerical information) and the first 50 were generated randomly. Thereafter the algorithm did its work. The paper provides much information on the fitness function used in the algorithm and the care taken in the definition of this in order to obviate spurious numerical results. Here is another quote from the paper:
    quote:
    It is important that the evaluation method -- here embodied in the analogue integrator and the fitness function Eqn. 1 -- facilitates an evolutionary pathway of very small incremental improvements. Earlier experiments, where the evaluation method only paid attention to whether the output voltage was above or below the logic threshold, met with failure. It should be recognised that to evolve non-trivial behaviours, the development of an appropriate evaluation technique can also be a non-trivial task.

    So the precise form of the fitness function is critical to the experiment’s success. It is essential that the algorithm can detect very small incremental improvements in fitness and then maintain them for the subsequent generations. Is natural selection in biology that fussy?

    Here is a comment from the paper on the first (random) generation:
    quote:
    The individual in the initial random population of 50 that happened to get the highest score produced a constant +5V output at all times, irrespective of the input. It received a fitness of slightly above zero just because of noise. Thus, there was no individual in the initial population that demonstrated any ability whatsoever to perform the task.

    So again, considering the numerical strings as an animal analogue, all the initial “creatures” were unable to demonstrate any fitness at all. Nevertheless they all survived to “breed”. In the cyberspace of a numerical experiment nobody dies young and all can get to breed.

    This complete lack of fitness lasted for many generations, but definite progress on fitness was reported after 650 generations. Around generation 1100 the output of the best individual in the numerical population was approximately as desired, but the average was well below perfect fitness.

    The overall population fitness then continued to improve until generation 4100 delivered perfect behaviour from all members of the population. A further 1000 generations delivered no discernible change at all – “stasis” had been achieved. The algorithm did not allow for the propagation of deleterious mutations or subsequent genetic drift.

    Further improvements were achieved by the intelligent intervention of the experimenters. They removed virtually (i.e. by numerical manipulation) parts of the chip not being used in the evolved circuit. This process demonstrated many unexpected subtleties in the behaviour of the chip that the real-time experiment had allowed for, including electromagnetic coupling independent of direct connections.

    Earlier on this thread I commented on the differences between “constrained” and “unconstrained” evolutionary algorithms. I consider that this is an example of unconstrained evolution, starting with an completely unfit (i.e. dead or unsuccessfully breeding) life-form and passing through many unfit stages (but still breeding), until the numbers enter a region where the fitness function starts giving desirable answers. Judging by the following comments in the paper, the authors agree that this was an unconstrained evolutionary process:
    quote:
    Thus, conventional design always requires constraints to be applied to the circuit's spatial structure and/or dynamical behaviour. Evolution, working by judging the effects of variations applied to the real physical hardware, does not. That is why the circuit was evolved without the enforcement of any spatial structure, such as limitations upon recurrent connections, or the imposition of modularity, and without dynamical constraints such as a synchronising clock or handshaking between modules. This sets free all of the detailed properties of the components to be used in developing the required overall behaviour. It is reasonable to claim that the evolved circuit consequently uses significantly less silicon area than would be required by a human designer faced with the same problem, but such assertions are always open to attack from genius designers.

    So, although the engineers involved are to be congratulated on their achievement, this process is very far from being a model of Darwinian evolution in biology. It is a good demonstration of what a well-designed numerical process can achieve in a large multi-dimensional search space.

    Justinian did indeed say that: "It was also a solution that the creator would never have come up with." But his point is surely not intended theologically. It is surely intended to emphasise the point that the solution to the problem that the algorithm came up with was NOT a solution designed by the creator of the program.

    It is a frequent, and erroneous, objection to these kinds of analogies for evolution that, just because there is a person involved somewhere in the setting up of the program, the solution produced by the program is therefore designed, because there is a person around to label the designer. That, I am sure, is the kind of view that Justinian is attacking.

    The particular program that you describe is clearly not a model of biological evolution (it was modelled on natural selection) but it still remains analagous to it. The key question, therefore, is whether the differences between it and nature that you point to make evolution by natural selection improbable. The answer to that is surely 'no'.

    On further reflection it's possible that I have misunderstood Justinian at this point. He may have meant "creator" in the sense of "human creator", i.e. the engineers on the project, in which case his comment is psychological rather than theological - it presumes a certain constrained mode of human thinking. I am more comfortable with this.

    With probabilities of the order of 10E-542, I think it's fair to say that a human engineer, given the same task, may have come up with a very different solution, indeed if at all. Justinian's reference suggests that before the start of the experiment many were very sceptical that any chip configuration giving the desired functionality was going to be possible with the given constraints.

    In my original reply I took "creator" in the sense of "supernatural creator", i.e. God, and hence commented on the implied theology in the comment. This follows on from some of the comments in my earlier posts and the linked paper by Nelson on the use of theological arguments (either intentionally or by accident) in the writings of many Darwinists.

    Clarification: Creator in this case referred to the human creator of the experiment rather than God.

    Also it was an experiment done physically rather than in computer modelling - computer modelling would not have come up with that solution either - if it came up with a solution at all, the solution would have had all the cells involved actually connected to each other (unlike this one) unless you could model the exact physical properties into the algorithm (which would take a massive amount of information).

    IIRC when New Scientist covered this, they also commented that the solution used fewer than the theoretical minimum number of parts to measure the frequencies.

    Neil made a number of comments in his post of 10 July, 2004 16:13 pointing to what he saw as differences between the evolutionary configuration of the microchip and natural selection in biology. None of them, however, imperils the analogy between that process and natural selection.

    A population of 50 would be considered to be on the brink of extinction. Natural populations are usually much better endowed with thousands to trillions or more members depending on the type of organism. Populations may also be fairly stable in numbers over generations though this is not critical for natural selection. An organism with a highly deleterious mutation dies and does not breed so provided that the rate of such mutations is not too high it does not imperil the survival of the species.

    quote:

    Any change in an organism that gives it even a slight advantage over the other members of its species will tend, on average, to improve its chances of reproducing. As it gradually spreads by inheritance through the population then that advantage will be present with more members and thus even more likely to increase. So, yes, it can be fussy.

    But this makes the mistake of measuring fitness in terms of one criterion only. An animal species that has no lens in its eye may be entirely ‘unfit’ in terms of having a lens, but that does not mean that it is not well adapted to its environment and ‘fit’ in many respects. It would not die just because it lacked a lens.

    quote:

    The algorithm did not allow for the propagation of deleterious mutations or subsequent genetic drift.

    Deleterious mutations are generally kept at low levels in populations by the fact that they hinder reproductive success and so don’t get replicated so often. Genetic drift that disturbs the function of beneficial mutations also gets weeded out or kept at low levels by selection. Drift which is neutral has no effect on the evolution of the trait in question.

    quote:

    I consider that this is an example of unconstrained evolution, starting with an completely unfit (i.e. dead or unsuccessfully breeding) life-form and passing through many unfit stages (but still breeding), until the numbers enter a region where the fitness function starts giving desirable answers.

    See comments on ‘fitness’ above as to why this is not relevant.

    Sorry to double post but I just noticed that In your earlier post you said that “This complete lack of fitness lasted for many generations, but definite progress on fitness was reported after 650 generations.” This would be an important point, but I can't find anywhere in the paper that says there was no fitness at all in these earlier generations. Have I missed something?

    Glenn

    The relevant part of the paper is here. Unfortunately, the graphical results in the paper are mostly illegible, so it is necessary to rely on the textual description.

    The fitness of the first trial generation (produced randomly) is reported as follows, with my emphasis:
    quote:
    The individual in the initial random population of 50 that happened to get the highest score produced a constant +5V output at all times, irrespective of the input. It received a fitness of slightly above zero just because of noise. Thus, there was no individual in the initial population that demonstrated any ability whatsoever to perform the task.

    So all the initial life-forms were completely unfit, demonstrating none of the desired behaviour (i.e. +5 volts dc output at 1 kHz input; 0 volts output at 10 kHz input). Nevertheless, the algorithm kept doing its work. At 220 generations they report the first microscopic hints of fitness:
    quote:
    After 220 generations, the best circuit was basically copying the input to the output. However, on what would have been the high part of the square wave, a high frequency component was also present, visible as a blurred thickening of the line in the photograph. This high-frequency component exceeds the maximum rate at which the FPGA can make logic transitions, so the output makes small oscillations about a voltage slightly below the normal logic-high output voltage for the high part of the square wave. After another 100 generations, the behaviour was much the same, with the addition of occasional glitches to 0V when the output would otherwise have been high.
    Note the tentativeness of the description here. I suspect that one of the reasons they had to define the fitness function very carefully is so that the algorithm could identify these first microscopic hints of fitness and then progressively refine them.

    At generation 650 through to 1100 they report “definite” progress, as follows:
    quote:
    Once 650 generations had elapsed, definite progress had been made. For the 1kHz input, the output stayed high (with a small component of the input wave still present) only occasionally pulsing to a low voltage. For the 10kHz input, the input was still basically being copied to the output. By generation 1100, this behaviour had been refined, so that the output stayed almost perfectly at +5V only when the 1kHz input was present.

    At generation 1400 they report futher progress, as follows:
    quote:
    By generation 1400, the neat behaviour for the 1kHz input had been abandoned, but now the output was mostly high for the 1kHz input, and mostly low for the 10kHz input...with very strange looking waveforms. This behaviour was then gradually improved.

    At generation 2800 they report almost perfect behaviour, and at generation 3500, perfect behaviour.

    For a quick summary of the fitness over all the generations, see figure 4 in this section of the paper. This shows the fitness graphically, both the average for the population, and also the maximum within the population. It also shows clearly the very unpromising start with zero fitness.

    There was a marked change in fitness behaviour around generation 2660, when the average fitness leapt markedly from a steady value of around 0.3 to a value of 1.0. They discuss this phenomenon in some detail in another paper, but unfortunately I don’t have access to that.

    The relevant part of the paper is here. Unfortunately, the graphical results in the paper are mostly illegible, so it is necessary to rely on the textual description.

    The fitness of the first trial generation (produced randomly) is reported as follows, with my emphasis:
    quote:
    The individual in the initial random population of 50 that happened to get the highest score produced a constant +5V output at all times, irrespective of the input.

    Neil, the figure four on the page you refer to is frustratingly unclear. Is that line from generation 0 to 220 above the zero fitness line or not - it is hard to tell. Presumably if there was no fitness at all in that time then they would have had to explain how they selected the individuals for breeding. They don't, so I imagine there was some but it is less clear than it might be.

    I am not entirely sure what relevance your point has to the question of whether this invalidates the experiment's analgousness to evolution by natural selection. As I said earlier "An animal species that has no lens in its eye may be entirely ‘unfit’ in terms of having a lens, but that does not mean that it is not well adapted to its environment and ‘fit’ in many respects. It would not die just because it lacked a lens." The fact that an initial population entirely lacks a trait does not render the individuals completely unfit nor the evolution of that trait impossible. So I am not clear what your point is with reference to the early lack of fitness. Perhaps you have something else in mind.

They don't, so I imagine there was some but it is less clear than it might be.

    The figures given in the paper are indeed frustratingly unclear, so I relied on the text. Note that fitness is defined numerically by equation (1) given here. The analogue integrator (shown in figure 2) acts as some kind of smoothing and averaging circuit, making more numerical sense of the spikes and quirks in the output.

    Despite the effectively zero values of fitness of the first generation, they were able to select the “fittest” one simply on the basis of electronic noise in the signal (either more or less, I’m not sure). Numerical “breeding” continued until the reported fitness was not simply a quirk of electronic noise.

    They were able to differentiate marginally between individuals with either zero or extremely low fitness through the skilful design of the fitness function. Reading between the lines of the paper, I suspect that considerable effort was expended in order to determine a suitable fitness function that could differentiate with such low fitness values around, as the following indicates (with my emphasis):

    quote:
    This fitness function demands the maximising of the difference between the average output voltage when a 1kHz input is present and the average output voltage when the 10kHz input is present. The calibration constants k1 and k2 were empirically determined, such that circuits simply connecting their output directly to the input would receive zero fitness. Otherwise, with k1 = k2 = 1, small frequency-sensitive effects in the integration of the square-waves were found to make these useless circuits an inescapable local optimum.

    It is important that the evaluation method -- here embodied in the analogue integrator and the fitness function Eqn. 1 -- facilitates an evolutionary pathway of very small incremental improvements. Earlier experiments, where the evaluation method only paid attention to whether the output voltage was above or below the logic threshold, met with failure. It should be recognised that to evolve non-trivial behaviours, the development of an appropriate evaluation technique can also be a non-trivial task.

    So, just to emphasise the point, the fitness function was “intelligently designed” to do its job in the algorithm.

    One of the assumptions in this experiment is that even the tiniest amount of fitness does convey some advantage, and so is chosen accordingly. In other words, fitness is not a binary on/off type condition, but can be graduated infinitely. Without this assumption it is clear to me, based on the initial lack of fitness, that the experiment would not have delivered any usable results.

    The experiment thus has built into it from the start the Darwinian assumption of gradualism, with improvement coming through tiny incremental steps, and a fitness function that can discern this. This assumption has delivered results in electronics, but only because the experiment was skilfully designed to do just that.

    The key question, as always with numerical models, is how close the numerical processes mirror the physical reality. Can advantageous biological traits be so infinitely graduated? And can the biological fitness function (i.e. natural selection) be so finely tuned? To my mind these are both very questionable assertions.

    Your comment about eyes reminds me of Richard Dawkins’ (in)famous comment that “5% of an eye is better than no eye”. This comment presumes that we have developed some functionality in the nascent eye physiology, i.e. that 5% of a nascent eye delivers an improved function in comparison to no eye.

    This is only true if we presume a linear type of relationship. However, biology certainly doesn’t always work that way. Non-linear relationships and binary on/off states are common. This brings us full circle to irreducible complexity, and the biological trait that only works at all when it is fully complete. A string of numbers is not nearly so constrained.

    They're only questionable if you use the words to mean something other than their common meaning.

    The role of fitness in evolutionary biological thinking is as a measure of whether you have more offspring or not. A very minor increase in fitness will thus *by definition* result in more offspring. It can be a very small increase in offspring - maybe only one or two extra per thousand births - but that's fine. In a large population over long time periods, that sort of increment is very important. Tiny changes come to light through statistics all the time: the smaller the change, the more data you need but there's no cut-off point where a change is too small to be registered under any circumstances.

    It is not thus possible by definition to have an increase in fitness too small to have any effect. Not 'highly questionable':impossible.

    Let's turn that around. In other words, 5% of an eye (let's say a light-sensitive spot) will *not* deliver an improved function in comparison to no eye if there is no 'linear type of relationship'?

    I fail to understand what you're saying here. To my mind, an animal that can sense the environment around it more accurately than one that can't, will find it advantageous. I cannot imagine any circumstances where this will not be.

    Perhaps you could explain under what circumstances an animal with a light sensitive spot is not at such an advantage, and how that illuminates (excuse me) your 'non-linear relationship' (between what and what?). Or perhaps you could explain what I'm misunderstanding?

    But - as has been stated so often - there are perfectly valid ways through standard evolutionary biology to get to a biological system that is complex and only works once complete. That's one of the great failures of ID - it hasn't identified any system where preliminary systems and transistions cannot be proposed.

    One of the great favourites of the ID apologists, the bacterial flagellum, has been the recipient of much lively debate among biologists, and there are many approaches that may explain its evolution in strictly standard terms. As that paper merrily says, not all of these proposals can be right. It is quite possible that they're all wrong. But there is no point in the flagellum design that is logically unbridgeable by standard evolutionary theory: ID says that there is, but has failed to identify it.

    So, the problem you propose that the model may not address doesn't exist, and the lack of correspondence between the model and nature doesn't exist either. (there are plenty of other lacks: it is, like Camelot, only a model.)

    Well, the circumstance where that particular sense is unable to function anyway would be an obvious example. So, in an environment with no light source the value of light detection systems will be very limited (ie: only of use if coupled with some means of light generation), and assuming there is a cost to eyes in terms of the need to produce certain proteins etc then there will be an advantage to having no eyes - which is what we see. Anywhere where the cost of an "improvement" outweighs the advantage gained will behave similarly - so humans don't have the ability to see like hawks as we don't need to be able to do so not hunting small animals from a distance.

    Neil: In this case, the system was set up intelligently. This does not mean that it produced results that would have been expected if designed from the top down- it is a case that shows that an evolutionary algorithm can come up with unexpected results. It is also an irreducibly complex object made up of not particularly complex parts (thus blowing that argument out of the water as well).

    That experiment had to be designed intelligently because the system had no way of moving on to the next step- this had to be supplied by experimenters. In an atheistic worldview, there is no experimenter therefore the successful objects (at any level) are either formed easily or last a long time and are almost immutable. There are two obvious ways of doing this: either being formed very easily (so there will always be a lot of you around even if you break apart) or by being incredibly stable so that even if there isn't much of you, there will always be some of you. (Most of chemistry is based on these two principles- although they are called bond energy (stability) and entropy (how likely something is to form)). There is also a third and much subtler solution- self replication, and it is this that is responsible for living things.

    The fitness criterion changing over time is nothing new- whether through natural disaster, a changing environment or just gradual improvement (look at most athletic records), what is considered fit does change over time.

    In such cases, and as to why we can't see small voles from two hundred feet, then surely the useless (and costly) modification just won't be selected for - so it won't survive in the population anyway.

    I was rather assuming that we were talking about features that had evolved, rather than transient neutral or deleterious mutations.

    The use of the word 'infinitely' misrepresents the experiment. The experiment did not rely on the absurd notion of an infinitely small improvement in fitness and neither does evolutionary theory.

    In any case Neil, nothing you have said shows that this experiment is not a good parallel to cases of natural selection operating on a trait that variation can improve in small steps.

    The experiment is, therefore, evidence towards the validity of the concept of natural selection and is, emphatically, strong evidence against the Intelligent Design proponent William Dembski's idea that selection cannot create what he calls complex specified information. (If he still holds that view nowadays.)

    In any case I thought you accepted micro-evolution, Neil, so I am a little puzzled as to your critique of the experiment. Or do you accept micro-evolution but believe that it does not happen by natural selection?

    My comment on “linearity” drew on the fact that humans and chimpanzees share 98% of the same DNA, yet we are dramatically different creatures. To me that indicated a very non-linear relationship – a 2% change has produced amongst other things the human capacity for intellectual and artistic achievements – a massive difference. On this basis it is by no means obvious to me that biology is linear.

    Dawkins’ rhetoric about the obvious superiority of 5% of an eye was his attempt to demonstrate the essential Darwinian component of gradualism, and presumed that the function delivered by a nascent evolving eye could be measured in simple percentage terms. His argument assumes that it makes biological (and indeed philosophical) sense to talk about 5% of an eye.

    By this I think he meant 5% of the functionality of an eye, but this requires much further definition from a scientific viewpoint. Is that a physiological 5%, or an optometrist’s 5%, or a biochemical 5%, or a brain processing 5%, or something else altogether? 5% of what? Vision is a very complex phenomenon indeed, and to treat it in the simplistic linear fashion that Dawkins does skates over some enormous problems.

    With regard to your comment on the “advantage” of eyes, it’s clear that many organisms have no eyes or vision of any kind, as Alan says. I think there are some deep water fish which have eyes but have lost (or never had) all vision. It’s clear that functioning eyes are not always necessary for successful life.

    Actually, in the last paragraph I would reverse the order of the auxiliary verbs, and firm up the language. The experimental model definitely does not address the problem of irreducible complexity, and in my engineering judgement such a problem does indeed exist.

    The configuration of the chip was governed by 1800 bits held in the computer. According to the authors of the paper, no possible numerical configuration was physically damaging or lethally destructive to the chip. It therefore follows that there is always a safe sequential route from any one configuration to any other configuration changing only one bit at a time.

    Consequently this experiment cannot possibly test the notion of irreducible complexity, since the way the experiment was set up bypassed any such possibility. For a design problem in electronics that was a reasonable experimental approach, but it simply begs the question in biology.

    I appreciated the link to the Matzke paper, although it is very technical. I have enough maths and physics to comment on electronics with some confidence, but I am less confident in biochemistry, so I will leave it to others to critique this paper. Has it been published in a refereed journal yet, or did it go straight to the web? In any case I think it is fair to say that if Behe had not written his book on irreducible complexity, this paper would not have been written.

    The experiment certainly surprised people, since many predicted that a suitable chip configuration for the given function would never be found. The technicalities of microchips are not my forte, but I noticed that the experiment was quite deliberately set up to use logic gates in a very unorthodox and highly experimental manner. This was equivalent (in terms of the laws of physics) to Rolf Harris making music with a violin bow on a large saw.

    On irreducible complexity, see my comment above to Rex Monday, and earlier comments on the graduated nature of fitness function. Note that what was evolved was a numerical configuration for a particular part of a chip, and not any kind of object. The evolved configuration was definitely not irreducibly complex, since we can track it and demonstrate some numerical fitness (as defined in the experiment) at every stage of the way.

    That we can do it in this case for an electronic circuit does not mean that we can do the same for every biological system.

    I used the word “infinitely” in parallel with “tiniest amount of fitness” and “finely tuned”. I don’t think this is a misrepresentation at all. The numerical fitness function used in the experiment allowed the algorithm to decide numerically to the arithmetical precision limit within the computer itself. In the first generation it was only more or less noise (and some fine tuning of the fitness function) which made any difference to the fitness.

    Here is how they “bred” the next generation, with my emphasis:
    quote:
    The population of size 50 was initialised by generating fifty random strings of 1800 bits each. After evaluation of each individual on the real FPGA, the next generation was formed by first copying over the single fittest individual unchanged (elitism); the remaining 49 members were derived from parents chosen through linear rank-based selection, in which the fittest individual of the current generation had an expectation of twice as many offspring as the median-ranked individual. The probability of single-point crossover was 0.7, and the per-bit mutation probability was set such that the expected number of mutations per genotype was 2.7. This mutation rate was arrived at in accordance with the Species Adaptation Genetic Algorithm (SAGA) theory of Harvey [4], along with a little experimentation.

    So the numerical fitness of each “creature” was clearly established at all times. Fitness was a numerical function governed by equation 1 in the paper, which is a mathematically continuous function related to the analogue integrator output. Subject to the arithmetical precision limits of the computer, I consider that an “infinite graduation” of fitness is a fair comment on how the experiment was set up.

    As Rex Monday noted above, the experiment could be criticised from a biological perspective in other areas. Note the constant elitism associated with the fittest individual, which is protected from breeding and simply copied unchanged to the next generation. This technique gradually and deliberately ratchets up the fitness of the whole population. This is perfectly reasonable in a numerical search algorithm, but is a teleology forbidden to biological Darwinism.

    Note also the absence of highly deleterious mutations. I suspect that a mutation rate of 2.7 per genotype would cause catastophic effects in a real population of 50 animals. Such a population is admittedly low, but not unrealistic for some rare birds of prey in Scotland, for example.

    In any case I thought you accepted micro-evolution, Neil, so I am a little puzzled as to your critique of the experiment. Or do you accept micro-evolution but believe that it does not happen by natural selection?

    Dembski’s ideas on “complex specified information” (CSI) have been developed mathematically with some rigour, but of course he is not without his critics. However, I believe that he still holds them and defends them as necessary.

    Your comment on natural selection creating CSI can only be sustained if you first demonstrate that the algorithm is a fair representation of biological natural selection as understood in Darwinism. In my opinion this particular experiment has not achieved that, nor did it set out to do so.

    I have no problem accepting microevolution by natural selection. This mechanism works on latent and unexpressed genes (such as moth colouration) that already exist. To my mind this is demonstrable science, and accordingly I have no argument with it.

    However, to create the new biological structures required by an evolutionary paradigm requires a mechanism that can create new and coordinated genetic information – and on a continuously grand scale. Artificial selection (i.e. animal and plant breeding) has shown a clear species boundary, and the few speciation events observed scientifically seem frankly trivial in comparison to the claims being made for them.

    So, if artificial (i.e. intelligent) selection cannot produce any macroevolution, then I see even less evidence that an undirected natural selection can do so. I consider natural selection a demonstrably failed scientific hypothesis for that kind of creative task.

    I do not rule out all macroevolution a priori, and I am intrigued by the non-Darwinian evolutionary models, which see macroevolution as a front-loaded process akin to the growth of an embryo. However, along with IDists, I do consider that without an explicit teleology the scientific research into biological origins is hopelessly handicapped.

It just shows some behaviour claimed by many influential creationists to be impossible (and I'm sure you'll agree that an argument that something can't be done is trumped by proof it has been).

    Neil, I am not claiming that they present clear evidence that evolution has happened - that is simply your misconception. What I am claiming is that they present proof that some of your cherished arguments against evolution are flat out wrong - things that it is claimed are impossible could both happen have been shown to do so. To claim that such models show that biological darwinism clearly happened (rather than simply that many of your objections are false) is your misinterpretation, and although to accidently construct such a strawman is a stupid mistake, I am prepared to apologise for extrapolating the fact that you have both started and maintained such a stupid strawman on this thread to the conclusion that you are stupid. If this is the case, then we all do stupid things and calling you either stupid or wilfuly blind for doing something stupid is one of my stupid mistakes.

    Amongst your responses to the experiment, you have come up with a number of objections that the experiment doesn't show certain things shown in the real world. No experiment we could do ever could have the correct initial parameters for the real world, and hence there will always be something missing. This is true for all scientific experiments in any field - and here you bring in such arguments as the mutation rate being much faster than in a real world biological system. Tell me, as an engineer do you ever use models that only simulate a part of the design? Do you ever use models that are not built at 100% scale and in the real world?

    The experiment is, therefore, evidence towards the validity of the concept of natural selection and is, emphatically, strong evidence against the Intelligent Design proponent William Dembski's idea that selection cannot create what he calls complex specified information. (If he still holds that view nowadays.)

    In any case I thought you accepted micro-evolution, Neil, so I am a little puzzled as to your critique of the experiment. Or do you accept micro-evolution but believe that it does not happen by natural selection?

    Dembski’s ideas on “complex specified information” (CSI) have been developed mathematically with some rigour, but of course he is not without his critics. However, I believe that he still holds them and defends them as necessary.

    Your comment on natural selection creating CSI can only be sustained if you first demonstrate that the algorithm is a fair representation of biological natural selection as understood in Darwinism. In my opinion this particular experiment has not achieved that, nor did it set out to do so.

    But Dembski declares selective algorithims on computers to be as incapable as natural selection in creating 'complex specified information'. He draws no distinction between them but damns all trial and error processes as mere combinations of chance and necessity and therefore incapable of generating 'complex specified information'. The experiment we have been looking at refutes that assertion and thus makes his claims against evolution highly doubtful at best.

    For example in his article Intelligent Design as a Theory of Information he says:
    quote:
    "If chance and necessity left to themselves cannot generate CSI, is it possible that chance and necessity working together might generate CSI? The answer is No. Whenever chance and necessity work together, the respective contributions of chance and necessity can be arranged sequentially. But by arranging the respective contributions of chance and necessity sequentially, it becomes clear that at no point in the sequence is CSI generated. Consider the case of trial-and-error (trial corresponds to necessity and error to chance). Once considered a crude method of problem solving, trial-and-error has so risen in the estimation of scientists that it is now regarded as the ultimate source of wisdom and creativity in nature. The probabilistic algorithms of computer science (e.g., genetic algorithms-see Forrest, 1993) all depend on trial-and-error. So too, the Darwinian mechanism of mutation and natural selection is a trial-and-error combination in which mutation supplies the error and selection the trial. An error is committed after which a trial is made. But at no point is CSI generated." [my emphasis]
    But in where then, in the experiment that we have been looking at, did the complex specified information that was produced come from? We wound up with a complex and functional arrangement. This is an example of complex specified information. Where did it come from? Answer that and you can see that Demski's arguments against natural selection are worthless.

    And another couple of things to add to the post of mine just before this one.
    quote:
    Originally posted by Faithful Sheepdog I am intrigued by the non-Darwinian evolutionary models, which see macroevolution as a front-loaded process akin to the growth of an embryo.
    If you know of any such 'front loaded models' I would be glad to hear of them. As far as I can see the ID movement is solely and anti-darwinian-evolution movement with no positive proposals for an alternative explanation of the phenomena.

    quote:
    Originally posted by Faithful Sheepdog However, along with IDists, I do consider that without an explicit teleology the scientific research into biological origins is hopelessly handicapped.
    Biologists have an equivalent to the teleological perspective, it is called 'adaptation', i.e. the concept that structures and systems are produced by evolution that have functions that enable the organism in question to survive and reproduce. It is highly obscure to me how the ID community think that the design hypothesis gives them any advantage over non-ID biologists in the practice of research. There is a paper by Jonathan Wells (adobe acrobat format) called Using Intelligent Design Theory to Guide Scientific Research that looks as if it might answer my bafflement, but utterly fails to do so. He gives an example of how he used design theory to guide his research and this appears to boil down to "In the electron microscope, centrioles look like tiny turbines. Using TOPS [Theory of Organismal Problem-Solving]as my guide, I concluded that if centrioles look like turbines they might actually be turbines."

    There is absolutely no resaon why a Darwinian might not think this thought! The darwinian supposes that the centriole has a function and is interested to know what that may be. Where does his non-belief in Intelligent Design prevent him from having a thought like "if centrioles look like turbines they might actually be turbines (albeit not made of sheet metal etc)"?

    And Well's suggestion that "Centrosomes … have never been a favorite object of study within the framework of Darwinian theory, because even though they replicate every time a cell divides they contain no DNA (Marshall and Rosenbaum, 2000), and they have no evolutionary intermediates from which to reconstruct phylogenies (Fulton, 1971)." is simply silly. Physiologists and biochemists and cell biologists are interested in function which can be, and usually are, investigated without evolutionary questions in mind.

    If you have a better idea as to why Intelligent Design is supposed to be so radically helpful in research please let me know.

    Centrioles aren't turbines. I promise you. You heard it hear first.

    Justinian, your apology is welcome, such as it is, but your use of the phrases “stupid mistake” and “stupid strawman” undermine any of the good in it. I am as capable of misunderstanding as anyone – especially over the limited medium of the Internet – but you misrepresent my argument whilst continuing to hurl insults.

    You didn’t introduce the article on the success of genetic algorithms in electronics for my general education and welfare. In the context of this thread these algorithms were submitted as evidence for a line of argument regarding the creative powers inherent in a Darwinist random mutation and natural selection scenario. Here are your words from 29/6/04, with your original emphasis:
    quote:
    Constrained systems can come up with new solutions- one case comes to mind where there was an attempt to see how to make a tone detector using the lowest possible number of parts in an electric circuit- and it came up with a solution using fewer than the theoretical minimum number of parts- and a solution in which some of the necessary parts were not even part of the circuit - meaning that in some cases it was the physics of the individual cells that was affecting the circuit, not their properties as part of the circuit.

    How's that for creation of something new via a genetic algorithm?


    and you went on to say on 1/7/04:
    quote:
    Part of the point is that the optimal solution wasn't just defined by the 1800 bits of information- the solution also involved the physical properties of the board- making for a more efficient solution, but one that was untransferable and completely breaking the chance of encoding the information in terms of a relatively small number of bits. It was also a solution that the [human] creator would never have come up with.
    and then finally you said on 11/7/04:
    quote:
    Also it was an experiment done physically rather than in computer modelling - computer modelling would not have come up with that solution either - if it came up with a solution at all, the solution would have had all the cells involved actually connected to each other (unlike this one) unless you could model the exact physical properties into the algorithm (which would take a massive amount of information).

    IIRC when New Scientist covered this, they also commented that the solution used fewer than the theoretical minimum number of parts to measure the frequencies.

    That appears to be the sum total of your initial argument on these algorithms.

    I have not denied that the experiment was very successful, nor that the solution to the electronics problem was indeed a novel one, but you have conspicuously not made any argument for a link between these algorithms and Darwinism. If you are going to submit these numerical algorithms as providing some insight into biological Darwinism, then the onus is on you to demonstrate their relevance to the biological processes, other than the linguistic similarities in the word “genetic”.

    My argument all along has been that the processes in these algorithms are working in a far-from-Darwinian fashion. If I am correct in this, either partially or completely, then their value as insight into biological Darwinism is much reduced, and they may even become part of the evidence against Darwinism. [Eek!]

    It is also clear to me that there is some confusion on your part over the notion of irreducible complexity. Here is how irreducible complexity was originally defined by Behe, as quoted on our old friends Talk Origins:
    quote:
    By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning. An irreducibly complex system cannot be produced directly (that is, by continuously improving the initial function, which continues to work by the same mechanism) by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional. An irreducibly complex biological system, if there is such a thing, would be a powerful challenge to Darwinian evolution. (p. 39)
    For a system to be irreducibly complex the fitness function must be a simple binary on/off measure. Either it works in some fashion – any fashion – or it grinds to a complete and total halt – “effectively ceases functioning”, as Behe puts it. That’s all that is needed. Think of a petrol engine car without a distributor arm – any distributor arm, even an electronic one – and you’ll see what I mean. It’s fitness as a binary integer function, which is a fundamentally different mathematical concept to fitness as a real continuous variable.

    This experiment was explicitly designed to rule out the applicability of such a concept from the very start. I have previously laboured the point that the fitness function in this experiment was a mathematically continuous positive variable. Any value greater than 0 was adequate for nomination as the fittest “creature”, provided that this value was greater than its neighbours, even if only due to noise.

    The discussion section of the paper itself provides considerable evidence that the final circuit could be modified slightly and still retain most of its function – see here. In the terms of the paper, the final circuit was definitely not irreducibly complex as understood by Behe.

    Now, over to you, I want to hear some substantial arguments as to why this experiment in particular and these algorithms in general shed some light on biological Darwinism. You consider that “they present proof that some of my cherished arguments against evolution are flat out wrong”. Now is the time to demonstrate it rather than simply asserting it.

    Use of mathematical jargon to restate something that is not an accurate model doesn't make it an accurate model. It just obfuscates it for non-mathematicans.

    In real life biological fitness isn't a function. It's a count - the number of of descendents something has. And it is of course contingent, historical. The continuously variable fitness numbers used in models are just that, models. And deterministic equations are very bad models of evolutionary or ecological processes. Stochastic ones better, but individual-based modelling better still.

    It might be the case that in some parts of physics the equations used to describe things are the "real" description and the English words a mere approximation for the innumerate. That's not the case in biology. Lots of people are misled by treating the deterministic equations used in biological models as "real". They're not - they are just approximations that are easier to calculate.

    If I say that one character has a fitness of 1, and another of 0.99 that's just a sort of statistical prediction. (& ought to be accompanied by a variance to be really accurate!). If I observe a real population of organisms (or a realistic stochastic or IB model) I will see how many offspring are actually born. And that number is the fitness. There are no hidden variables. Everything is dependent on the environment. If I think the fitness of one character should be 0.99 but in fact the bearers of that character only have 0.98 as many offspring that's not an error (in the common English sense of error - it is in the statistical jargon sense of course). It's just that the real outcome fitness has varied from the model. That outcome depends on many interactions between individuals, on many random occurences. There is no secrfet inner true fitness which is more or less expressed - the real fitness is the outcome, not the prediction. Even in a model.

    NBB - fitnesses are relative anyway (one of the reasons that all that stuff about mutation load is guff). If you got a population and magically mutated all their genomes so every one of them had on average a fitness of 0.9 that doesn't mean the population would fall to 90% of what it was. Because there woudl be no competition against fitter genomes, so that in practice they would actually have a fitness of one. The concept of fitness only works in a context of competition - effectively all organisms being able to reproduce themsleves many times over in the absence of competition or limitation by scarce resources.

So by definition that biological thing cannot have evolved. A fun mathematicians trick, but in the end not anything to do with biology.

This is an example of complex specified information. Where did it come from? Answer that and you can see that Dembski's arguments against natural selection are worthless.

    In Dembski’s writings “complex specified information” (CSI) is a technical term that is defined mathematically with some rigour, drawing on accepted results in information and probability theory. He has argued that any CSI with a probability level of less than 10E-150 may lead to a design inference. This number is not totally arbitrary, but is derived from some fundamental physical constants of the universe.

    In the experiment we have been looking at, the probability of the successful configuration being achieved by a random guess is 10E-540. So it appears to be correct to call the final configuration CSI in Dembski’s terms. I certainly agree that it is highly improbable that the correct configuration could have been achieved by a random guess. And using a human technician, successive trial and error would take far, far too long to be practical.

    In order to speed up the process dramatically, the experiment was set up on a human-constructed computer. Like all computers, this can do calculations far quicker than any humans, but the instructions to the computer as to which calculations and on which numbers were provided by humans. All the computer provides is brute number crunching.

    So, you are not correct to attribute the creation of the final information to the computer. That information was created by humans in the numerical parameters of the human-designed experiment, and also by humans in the physical properties of the human-constructed microchip, and yet again by humans, in the especially precise way in which humans defined the fitness function.

    All the computer did was sort through many existing numbers to find an optimum value (actually a population of 50 optimum values) very much quicker than any human could do. It took the computer 2 to 3 weeks to complete all the calculations, but the resulting information was created by humans, not by the computer.

    quote:
    Glenn Oldham said:
    If you know of any such 'front loaded models' I would be glad to hear of them.

    These models consider that macroevolution is something which took place in the far past, and in some cases took place by saltation – that is, explicit large jumps. However, this process is not being observed today. The era of evolution is over; what we are now seeing is the era of extinctions. The speciation observed today is trivial in evolutionary terms, and not responsible for what the fossil record shows.

    One common factor in these models is that the normal processes of sexual reproduction are not responsible for evolutionary development. In fact, for a sexual species sexual reproduction serves to bring macroevolutionary development to a complete halt. This neatly sidesteps the problem that Darwinism has always had with sexual reproduction.

    One author you may wish to investigate is the Frenchman Pierre-Paul Grassé. He is no lightweight amateur, but a past president of the French Academy of Sciences. He is associated with development of the concept of stigmergy, the term for the apparent intelligence in large assemblies of unintelligent creatures, especially termites armies. See here for more information on stigmergy.

    He repudiates Darwinism forcefully in favour of his “front loaded evolutionary model” based on “internal developmental factors”. His book “Evolution of Living Organisms” was published in French in 1973 and in English in 1977. I have yet to read it, but I have to admit, it does intrigue me.

    Another character is a contemporary American university biology professor called John A. Davison, who has derived some of his evolutionary ideas from Grassé. You will find access to some of his papers and thoughts at the ISCID forums here and also here.

    He uses the ISCID board name of Novisad and is something of a prickly character, but then his anti-Darwinian views have got him into trouble with his university employers, so which came first? The important question should be whether his scientific ideas are sound, even if unconventional.

    Whilst many in the ID fraternity are clearly opposed to Darwinism, which they consider to be both a failed scientific hypothesis and a pernicious ideology restrictive on true scientific thinking, they are nevertheless open to many different scientific approaches, and from many different theological perspectives (or in the case of agnostic David Berlinski, none).

    Although many ID ideas and terminology have been co-opted by the young earth creationist (YEC) fraternity, it is important to distinguish clearly the very different approaches of the two groups. If you are used to doing battle with YECists, then I am not surprised that you find ID a frustrating subject. It’s much more open to mainstream science whilst simultaneously being much more subtle in its philosophical approach.

    My argument all along has been that the processes in these algorithms are working in a far-from-Darwinian fashion. If I am correct in this, either partially or completely, then their value as insight into biological Darwinism is much reduced, and they may even become part of the evidence against Darwinism. [Eek!]

    It is also clear to me that there is some confusion on your part over the notion of irreducible complexity. … For a system to be irreducibly complex the fitness function must be a simple binary on/off measure. Either it works in some fashion – any fashion – or it grinds to a complete and total halt – “effectively ceases functioning”, as Behe puts it. That’s all that is needed. … It’s fitness as a binary integer function, which is a fundamentally different mathematical concept to fitness as a real continuous variable.

    This experiment was explicitly designed to rule out the applicability of such a concept from the very start.

    This experiment involved a population of 50 individual circuits. Aspects of these circuits were subjected to a degree of random mutation. Those individual circuits which performed a particular function better than others were reproduced to a greater degree than the others. They were also interbred. Again, further mutation was introduced and the cycle was repeated again and again. Eventually a remarkably good level of function was produced.

    This already sounds remarkably like the neo-Darwinian notion of evolution by natural selection, and it is therefore very odd to say that it is “working in a far-from-Darwinian fashion” and to imply that the only comparison with Darwinism is the word ‘genetic’ in ‘genetic algorithm’.

    Since the experimenters did not want to die before the results of the experiment came in they used a high mutation rate and a rapid generation time. A lower mutation rate could have been used and a longer generation time. This would have slowed things down, but that could have been compensated for by using a population of far higher size.

    Now since neo-Darwinism holds that evolution proceeds in a step-by-step fashion and NOT in great leaps, it was perfectly correct and perfectly Darwinian to make the fitness test in the experiment one where the circuits features are compared with an ideal and if it approaches that ideal more than its fellows then it gets to breed more. (There are thousands of such features in nature: being taller, running faster, having an enzyme that is slightly more efficient, and so on. )

    To design the experiment with an all or nothing test for fitness where the change required is very, very large would not have produced the result (except by colossal chance). But such an experiment would not have been a Darwinian one.

    As has been pointed out earlier in this thread (which contains extensive criticism of Behe’s views) there are many ways in which a system that is irreducibly complex can evolve gradually.

    First of all if I caused any offence by my icon of beting my head against a wall I apologise. It was not intended as an insult to Neil, or anyone and it was my head, figuratively speaking.

    Neil,
    First of all, thanks for the links to the various ID articles in your last post.

    Second, and the subject of this post from me, I asked where the complex specified information of the final configuration of the 10 by 10 microchip came from. I said, quite deliberately, “answer that and you can see that Dembski's arguments against natural selection are worthless.” Let me explain why I said that. Judging by your answer you have rejected the argument of Dembski’s paper.

    After accepting that the final configuration of the microchip was sufficiently complex and improbable to count as ‘complex specified information’ you said:

    quote:
    Originally posted by Faithful Sheepdog: [with my italicisation G.O.]
    I certainly agree that it is highly improbable that the correct configuration could have been achieved by a random guess. And using a human technician, successive trial and error would take far, far too long to be practical.

    In order to speed up the process dramatically, the experiment was set up on a human-constructed computer. … the instructions to the computer as to which calculations and on which numbers were provided by humans. All the computer provides is brute number crunching.

    So, you are not correct to attribute the creation of the final information to the computer. That information was created by humans in the numerical parameters of the human-designed experiment, and also by humans in the physical properties of the human-constructed microchip, and yet again by humans, in the especially precise way in which humans defined the fitness function.

    All the computer did was sort through many existing numbers to find an optimum value (actually a population of 50 optimum values) very much quicker than any human could do. It took the computer 2 to 3 weeks to complete all the calculations, but the resulting information was created by humans, not by the computer.

    So on the one hand we have the humans an on the other we have the physical system (the computer with its settings and the microchip with its physical properties). The physical system has been designed by the humans. The physical system is then allowed to run and it follows a process modelled on natural selection – it tests a set of configurations for fitness and preferentially replicates the most fit, it then varies them slightly and randomnly and then repeats the cycle. It does this until the final result is reached of a highly fit configuration. That configuration is a state that is one of complex specified information. What the apparatus does is dictated by the laws of physics, the settings imposed by the software, and the random variation generated.

    You wish to describe this information as having been created by humans. I imagine that you would see it as an example of intelligent design. I imagine too that Dembski would argue the same thing.

    Now I think that the example reveals subtleties to what ‘design’ means that are often skated over in ID literature, where design is often seen as intelligence supplying the information of the final result direct to the system. BUT LET THAT PASS for the time being, for there is a more crucial difficulty for ID in the answer that you have given.

    It is that on the basis of your reasoning, evolution by natural selection on neo-Darwinian lines would itself be an example of Intelligent Design and the designer in this case would be whoever created or designed the natural world. The physical world, with its parts subject to the laws of chemistry and physics and its organisms subject to selection for fitness, replicating, varying will, where the conditions are right, generate complex specified information.

    It is one thing to argue that the natural world does not have time or sufficient sources of variation to operate natural selection and so on. That is to argue that Natural Selection does not occur. But the argument that Natural Selection cannot on principle generate complex specified information fails utterly, especially in the face of experiments like these.

    Glenn, no apology necessary, I certainly didn’t take it as an insult or a personal attack. The frustration induced by the difficulties of communication over the Internet is something I’ve certainly felt. It was Justinian’s later remarks to which I objected.

    quote:
    Ken said:
    Well, an engine with a slightly bent one [i.e distributor arm] would still work, yes?

    The key question to ask is whether the engine starts or not.

    A slightly bent distributor arm may still work enough to transmit the electrical spark at the right time, hence the engine starts, even if it subsequently runs a little roughly. In functional terms a distributor arm is still present.

    A more heavily bent arm may fail to work at all, at which point the engine fails to start at all, and we’re calling the breakdown service.

    The world of engineering is full of irreducibly complex systems, so this concept is almost intuitively obvious to me. The key question is whether the concept can be rightly applied to biological systems. You say:
    quote:
    Things like that are rare in nature if they occur at all.

    I myself see no reason to support this assertion. Machines are subject to the laws of physics. Why should biology not be?

    Note that Michael Behe is a biochemist, not a mathematician, a physicist or an engineer. For him, if Darwinian evolution is to be true, it must also satisfactorily explain the emergence of biochemical systems. It was his dissatisfaction on this point which eventually led him to write his book, Darwin’s Black Box, although the concept of irreducible complexity actually predates him.

    quote:
    Ken said:
    Use of mathematical jargon to restate something that is not an accurate model doesn't make it an accurate model. It just obfuscates it for non-mathematicians.

    My comment on integer versus real numbers was not intended to blind people with mathematical jargon. This difference was one of the first things I was taught in my engineering degree, with relevance to computer programming.

    An integer measure is counted in whole numbers, 1, 2, 3, 4 etc. A good everyday example is eggs – we buy them in the UK by the half dozen or dozen or whatever, but half an egg is simply not possible.

    By contrast, a real number can be a decimal figure to any number of places you like (subject to the limit of the measuring equipment in question). A good example is the value for Pi (the ratio of a circle’s circumference to its diameter), which is a real number that can be quoted to as many decimal places as you wish (3.14157……etc).

That is to argue that Natural Selection does not occur. But the argument that Natural Selection cannot on principle generate complex specified information fails utterly, especially in the face of experiments like these.

    There are many processes around us where complex assemblies are formed from the small incremental addition of new parts that in themselves are almost trivial. As a boy I called them jigsaw puzzles; as a professional engineer I call them skeletal steelwork structures. And we are all familiar with the process of writing, which begins with the first letter on the page, and ends up as a Booker prize-winning novel, or whatever.

    In broader terms it is absolutely essential to distinguish between processes which are intelligently driven towards a pre-programmed goal – a telic process in philosophical jargon – and the rigorously naturalistic form of Darwinism, enthusiastically championed by the likes of Richard Dawkins, where teleology is completely out, full stop.

    There is a brand of ID that would see natural selection as an intelligence-driven, goal-oriented process. The position of these people probably has much in common with what is sometimes called “theistic evolution”, presumably driven by God under the appearance of a Darwinian process. That seems to be the position of many on this thread, and indeed in the wider church, even if they would personally repudiate the term ID.

    However, for Dawkins there is no intelligence abroad in the universe other than ourselves. Natural selection as he understands it is an unintelligent process that cannot possibly have a target or a goal. It knows only about the present. It can access the past indirectly through genetically stored information, but it definitely does not know about the future. Dawkins’ Darwinism is for the church of the true believers - there is no metaphysics allowed at all.

    So a truly Darwinian process is not just one progressing in a step-by-step fashion. To be truly Darwinian it must be a process that truly does not know where it is going. It cannot have access to any form of ideal end goal, since that would be a form of teleology. To be truly Darwinian that cannot be allowed. At least, that’s how I understand it.

    Since Darwinism ascribes a great deal to natural selection, it is essential to be clear on what is meant by it. As Ken says, the proper description of natural selection is not in terms of a “mathematical fitness function”, but in terms of the relative number of descendants. Here is how he put it earlier:
    quote:
    In real life biological fitness isn't a function. It's a count - the number of descendents something has. And it is of course contingent, historical. The continuously variable fitness numbers used in models are just that, models. And deterministic equations are very bad models of evolutionary or ecological processes. Stochastic ones better, but individual-based modelling better still.
    In the light of these comments let’s look more closely at how the experiment operated:

    Firstly it assigned a fitness value to each individual in each generation by reference to equation 1 in the paper. This equation incorporates all the information necessary to specify the final end point, the goal of the process. For each individual an absolute fitness was established by constant reference to this desired end goal. The relative fitness of each individual was only then established, in a secondary and derivative manner, as the ratio of the absolute fitnesses.

    As Glenn Oldham put it, with my emphasis:
    quote:
    Now since neo-Darwinism holds that evolution proceeds in a step-by-step fashion and NOT in great leaps, it was perfectly correct and perfectly Darwinian to make the fitness test in the experiment one where the circuits features are compared with an ideal and if it approaches that ideal more than its fellows then it gets to breed more.
    So, we are both agreed that these algorithms have access to an “ideal” at all times – the specified end goal.

    Hence my first point is that these algorithms, by definition, cannot be a truly Darwinian process. They are driven throughout by a goal-oriented methodology, which is perfectly reasonable if trying to solve an engineering problem, but not if one is trying to model a Darwinian process.

    Secondly, having established a numerical fitness measure for each individual, the algorithm then mimics the breeding process, allowing for the possibility of random mutation. It determines the relative number of offspring based on assigned probability values. These probability values are derived from the relative fitness values - a relatively fitter individual has more offspring than a less fit one.

    But note what this implies: Since the relative fitness values are derived with reference to the absolute fitness values, and since the absolute fitness values are determined in relation to the final end goal, the algorithm ensures a priori that that individuals nearer to the specified target have relatively more offspring. So, if the target exists at all, it is no surprise when we eventually we hit it, since that was something the experiment intended all along.

    So my second point is that these algorithms are not modelling natural selection as understood within Darwinism. In them the selection process means “nearer to the specified target”, not “who has the most grandchildren”. The experiment is not counting the descendants, and then deducing a theory from that empirical data. Instead it imposes a deterministic form of differential breeding in a pre-determined manner.

    My third point is that this whole experiment was functionally deterministic, not stochastic. If the experiment was run again, it would converge to the same functional target. It is not free to do anything else. A true stochastic process would be free to give a different result and converge to some other functional target.

    So I want to stand by my comment that these algorithms are working in a far-from-Darwinian fashion, and they are definitely not demonstrating a Darwinian process.

    There is a long, detailed and highly technical article on genetic algorithms at Talk Origins here. The long factual description of the history of these algorithms is quite good, but if you scroll about 90% of the way down the page, there is a brief mention of our electronics experiment. The relevant paragraph begins :
    quote:
    However, genetic algorithms make this view untenable by demonstrating the fundamental seamlessness of the evolutionary process. Take, for example, a problem that consists of programming a circuit to discriminate between a 1-kilohertz and a 10-kilohertz tone, and respond respectively with steady outputs of 0 and 5 volts.
    And goes on to conclude, with their original emphasis:
    quote:
    The circuit evolved, without any intelligent guidance, from a completely random and non-functional state to a tightly complex, efficient and optimal state. How can this not be a compelling experimental demonstration of the power of evolution?

    On the contrary, this experiment was a compelling experimental demonstration of the power of humans to invent complex and sophisticated tools to help them solve their problems. That takes intelligence.

    quote:
    Glenn Oldham said:
    You wish to describe this information as having been created by humans. I imagine that you would see it as an example of intelligent design. I imagine too that Dembski would argue the same thing.

    I am intrigued by this comment – I presume that you disagree with my original comment about the human origin of the complex specified information in the experiment? Why do you think that the information was not created by humans?

    On a broader note I have heard it said that, in their enthusiasm to rule out metaphysical agency, Darwinists also inadvertently rule out human agency. The comment above on this experiment from Talk Origins seems to take this line. As a professional engineer trained to solve technical problems I must say that I find it absolutely extraordinary.

    Neil, They shed light in that they show from an evolutionary starting point that some of the objections raised are just plain wrong. They do not prove that evolution happened, and I'm sure can be used as the basis for new arguments against evolution, but in a number of cases new arguments are needed. The circuit is not an argument against ID via the mechanism of evolution (I don't think that that's remotely falsifiable without falsifying evolution- although Occam's Razor is an argument against it, as are the various odditites in evolution like nerves in the giraffe and unwanted extra fingers in birds), just against a string of arguments claiming that macroevolution could not have happened.

    One of the things thought by some to be impossible that was shown was speciation, with the best solution not working if you moved it onto the circuit board of the second best solution and vise-versa (they couldn't interbreed and were very different).

    Irreducible complexity strikes me as a chimera- a circuit can survive having some of the insulating plastic removed, but will break if it has the batteries or one of the conductors removed. Likewise a human can survive with an arm amputated, but not its brain removed. For that matter, most well designed engineering systems have built in margins of error and redundancies in order to cope with the real world.

    Finally evolution works in the real world by feeding back the current state of the world, meaning the system for determining optimality is extremely chaotic.

    I am grateful that nothing in your post attempts the futile task of trying to prove that Darwinian natural selection cannot in principle create complex specified information. (Which is what Dembski seeks to do on purely logical grounds).

    Organisms are tested against other organisms in terms of which of them are better able to survive and reproduce. What enables them to best do this changes over time. It is still a selective process as much as that in the experiment. If you want an experiment which models Darwinian evolution more accurately then this one is appropriate: The evolutionary origin of complex features- a pdf file

    You will note that complex specified information is generated.

    Finally, on the question of whether the humans created the information in the experiment we have been discussing: one could more accurately say that they designed a system that would search using a selection process and find one of an indeterminate number of configurations that would perform a certain function. The system then found it for them. Did they create that information? Did they design that final microchip? They certainly did not do so in most ordinary uses of the terms 'create' and 'design'. And it is the ordinary uses of those terms most people assume when they here talk about intelligent design. In the Lenski and Pennock experiment it is even further from normal usage to say that they designed the virtual creatures of their experiment.

    The argument from homology that Glenn has brought forward is an argument based on an inference from similar patterns. In essence his argument here is not dissimilar to that used in many ID circles, in which biological design is inferred based on comparison with a pattern from engineering systems. We are looking at the same facts, but drawing very different conclusions.

    Now I’m really confused - I can’t find this information at all in the paper. Can you link to the relevant section? They did repeat the experiment on a different 10x10 part of the microchip, using as a starting population of 50 the final evolved configurations from the first experiment.

    In the new location they found an immediate 7% drop in the fitness of the previously fittest individual, although another individual was now within 0.1% of perfect fitness. These differences are explainable by the random variations between the numerous micro-transistors on the chip. After another 100 generations in the new chip location, all members of the population had converged on perfect fitness.

    It’s essential to differentiate between positive and negative feedback from the environment. Negative feedback damps down a random mutation phenomenon and ensures that it grows smaller over time.

    With positive feedback the phenomenon will grow bigger over time. In real engineering systems there are limits imposed on the growth of the phenomenon by the emergence of non-linearity in the system. If you’ve ever seen the footage of the collapse of the Tacoma Narrows suspension bridge under wind induced vibration, you’ll know what I mean.

    In general positive feedback is certainly not beneficial in engineering, but of course, this begs the question in biology. Can positive feedback be applied to a biological system in a continuously beneficial fashion? Darwinism is a priori committed to the answer yes.

    Neil,
    Let me try to spell it out as clearly as I can. One of the arguments offered by some IDers and by Dembski in the article of his I posted earlier is that a system that generates complex specified information by random variation plus selection plus replication is impossible. Dembski's argument to this effect is purely logical. It does not raise questions of mutation rates or fitness functions or any of the matters that you have mentioned. It argues that chance, necessity, and design are the only causes around and that chance and necessity (working alone or even together) cannot generate complex specified information. He states this to be the case for natural selection and for genetic algorithms.

    It is this argument to the effect that natural selction is not possible that is refuted by the kinds of experiments that we have been discussing. Such arguments are shown to be plain wrong. (Dembsi's argument is fallacious on logical graounds as well, of course.)

    Now as to your arguments (rather than Dembski's) against the relevance of these experiments for natural selection, ... more tomorrow.

    That an evolutionary algorithm won't come up with a solution the designer couldn't have found. The solution found by an evolutionary method had parts of the circuit not actually connecting to the circuit- something no human designer would come up with. (IIRC that's the reason I brought this up in the first place)

    That "irreducable complexity" would not arise by means of natural selection. The thing is an irreducibly complex object that arises through natural selection.

    In trying to claim that I'm claiming more for them than I am. What I claim for the experiment is that it explodes some of your claims, which it does. What I am not trying to prove is that it thereby proves the whole of evolutionary theory.

    Once again I’m really not sure what you’re saying here. Why should Occam’s razor be applicable in the instance of a scientific question?
    Because your statement is not a scientific one. You have come up with an unfalsifiable and more complex modification to the theory being presented (that there is natural selection, selected by the creator). It is that sort of crap that Occam's Razor (do not multiply entities beyond necessity) was origionally trying to deal with.

    Being unfalsifiable, you are not presenting a scientific question, therefore methods for dealing with pseudoscience are quite sufficient.

    Yes. 1+1=2 is similar to 1+1=3. The problem is that your argument from design has many many anomilies like overlong nerves, extra bones running parallel to another set and seven vertebrae in the neck of a giraffe.

    I wish to withdraw this argument- although I believe it is valid, it is not solid enough to be used for argument. The only further thing I will say on the subject is to ask you to work out just how much can change in a solution with a 2.7% mutation rate per generation and 100 generations.

    Irreducible complexity strikes me as a chimera- a circuit can survive having some of the insulating plastic removed, but will break if it has the batteries or one of the conductors removed. Likewise a human can survive with an arm amputated, but not its brain removed. For that matter, most well designed engineering systems have built in margins of error and redundancies in order to cope with the real world.

    Has you car ever failed to start? That’s irreducible complexity in action for you.

    We have many things in twos – eyes, ears, lungs, kidneys, arms, legs - but how many back-up hearts do you have?

    None. Neither do I have a backup life. In order to have reducible complexity, you need for there to be two distinct but identical entities.

    On the other hand, the circuit indicated earlier developed through evolution rather than direct design- and it being an electronic circuit, it ipso facto was irreducibly complex as removing certain parts would break the circuit.

    So we have an evolved object that is irreducibly complex. Counter example presented.

    Finally evolution works in the real world by feeding back the current state of the world, meaning the system for determining optimality is extremely chaotic.

    It’s essential to differentiate between positive and negative feedback from the environment. Negative feedback damps down a random mutation phenomenon and ensures that it grows smaller over time.

    [SNIP]

    And natural selection uses both positive and negative feedback. It usually seems to use positive feedback until after a certain optimum point is passed then negative to get it back there.

    quote:
    In general positive feedback is certainly not beneficial in engineering, but of course, this begs the question in biology. Can positive feedback be applied to a biological system in a continuously beneficial fashion? Darwinism is a priori committed to the answer yes.
    Bullshit! First, not all mutations that are selected fo are continuously benificial- see sickle cell anemia, which has benifits at times (for dealing with malaria) but certainly isn't beneficial all the time. Secondly, situations change- what was beneficial in the ice age isn't beneficial with global warming. Thirdly, there appear to be some optimal forms- sharks haven't changed their basic design in aeons. Fourthly, and related, there may me maneuvering round an optimal point- taller humans have an advantage, but if I were to follow your simplistic summary, humans would be at least 60' tall- although there are negative feedback mechanisms working against this.

    You seem to have fundamentally misunderstood the mechanisms involved in darwinism.

    Neil,
    There are three main aspects of your arguments about genetic algorithms that I want to address. The first two are the questions of whether any new information is created by the experiments and, if so by whom. The second is whether these genetic algorithms are so different from natural selection that they have no evidential value for neo-Darwinism.

    1) On whether new information is created.
    In my immediately previous post I explained that one thing being claimed for these genetic algorithms is that they show that random variation plus selection plus replication is capable of generating new complex specified information. Now, since it is a claim of Darwinian theory that random variation plus selection plus replication is a key factor responsible for the adaptations of organisms to their environment, then experiments like this one clearly have relevance to that claim and provide evidential support for it. It is absolutely clear from this experiment (the 10 x 10 microchip one) that something new was produced: in this case it was a new configuration of a chip that had the ability to perform a complex electronic function.

    On an earlier post (30 June, 2004 23:14) you said:
    quote:
    Firstly, there is a sense in which the optimised design that emerges from the evolutionary algorithm can rightly be called new, since that particular combination of parameters has probably never seen the light of day before. …

    However – and this is the but – the algorithm cannot break away from the original N parameters and the programmed constraints to give us the answer to a problem with N+M parameters and a different set of constraints. The program begins with N parameters for a specific engineering problem, and finishes with N parameters – for that same problem. So in that sense nothing has changed. We simply have a more desirable set of numbers than we started with.
    […]
    So at the start, even before the algorithm has begun “number crunching”, all fitness values in the xyz space have been defined in principle by the programmed fitness function(s) and all the other constraints. There is a sense in which the program knows in advance the fitness values for all possible x, y and z values. The only problem remaining is the exact x, y and z location(s) of maximum fitness within the permitted region.

    The program does NOT know ‘in advance the fitness values for all possible x, y and z’ values. If it can be said to know anything it can be said to know how to calculate the fitness value. In this case if either the humans or the system knew the exact specification of the successful chip configuration ’in advance’ then they could have configured the chip straight away without having to run the random variation plus selection experiment to find it. In this case they could not.

    2) What creates the new information?
    When we turn to the question of to what we are to attribute the creation of the new information you quote from a paper that says: “The circuit evolved, without any intelligent guidance, from a completely random and non-functional state to a tightly complex, efficient and optimal state. How can this not be a compelling experimental demonstration of the power of evolution?” And then you remark on this: On the contrary, this experiment was a compelling experimental demonstration of the power of humans to invent complex and sophisticated tools to help them solve their problems. That takes intelligence. Earlier you said “The engineer has defined both the problem (where is the optimum?) and its solution (an efficient search algorithm). The numbers may be new, but the creativity belongs to the engineer. The algorithm is simply a creative tool in his or her hands.”

    But there is no ‘on the contrary’ or ‘simply’ about it, because the two perspectives are not mutually incompatible. In the chip experiment the humans designed the equipment and set the parameters for the selection process. They did indeed design the tool, and so without them the final result would not have been found. But it was the tool, the system, that found the exact configuration of the final chip. It was the system that generated the new information. The humans set the system up in the hope that it could do that, but they did not specify the final configuration of the chip in advance. They specified what the ideal chip should be capable of doing but that is not the same as specifying how it should do it. They did not work that out: the system worked that out. What this means is that it is in principle possible for a physical system to produce complex specified information. Populations of biological organisms exhibit random variation plus selection plus replication and thus can in the right circumstances generate increased complex specified information.

    3) Do these examples differ so much from natural selection that they have no evidential value for Darwinism?
    On several occasions, Neil, you have said of these kinds of experiments things like:

    “this process is very far from being a model of Darwinian evolution in biology”
    “My argument all along has been that the processes in these algorithms are working in a far-from-Darwinian fashion.”
    “these algorithms, by definition, cannot be a truly Darwinian process”
    “I want to stand by my comment that these algorithms are working in a far-from-Darwinian fashion, and they are definitely not demonstrating a Darwinian process”
    .

    3.1) Firstly, the (repeated) use of the words ‘far from’ is unjustifiable. These systems use random variation plus selection plus replication – the very elements of neo Darwinian natural selection. They are therefore NOT ‘far from’ a Darwinian process.

    3.2) But having said that one must still consider whether the algorithms are so far different from selection in the real biological world as to be worthless as support for neo-Darwinism. To make that point you have argued about things like the fitness function, mutations, constraint. These differences (and they vary depending on which algorithm we are talking about) do limit the extent of the conclusions that can be drawn from the algorithms. However, none of the differences, especially in the chip experiment we have been considering is such as to make them of no value.

    3.2.1) The argument about mathematics:
    You said on 23 June, 2004 11:31 of genetic algorithms: “I do not think that they are a model of Darwinian evolution, unless you are prepared to accept that natural selection can operate in a mathematical fashion according to intelligently determined numerical rules with a clear sense of purpose behind them.” But this has as little merit as saying that “I do not think that computer models of bridge behaviour a model of real bridge behaviour, unless you are prepared to accept that bridges can operate in a mathematical fashion according to intelligently determined numerical rules with a clear sense of purpose behind them.” Physical things of all sorts obey the laws of physics and chemistry and show statistical patterns and these can be modelled, more or less well, using numbers. There is nothing special about biology that rules out computer modelling [/I]a priori.[/I]


    But I am out of time and must return to the other points later. However most of them I have already covered in an earlier post of the 12 July, 2004 06:42. Your comments on fitness in particular seem to reveal a lack of acquaintance with that topic and with the concept of selection.

    Glenn, thank you for the reference to the Nature paper on AVIDA. As it happens, there has been considerable discussion on AVIDA in recent weeks at both the ARN and ISCID forums, so I was partially aware of this software. For anyone interested, it is available for free download to the general public here.

    I have printed out the Nature article and am presently studying it for myself. It is clear that AVIDA is substantially more sophisticated than the genetic algorithms we have discussed to date, so it may take me a while to get my head round the various logic functions that constitute an AVIDA “critter”. If I become confident that I understand how it is working (and at present I am not), then I may come back with some detailed observations.

    However, I do have one preliminary observation on the Nature paper: Nature is a prestigious scientific journal, yet the paper cites as a reference “The Blind Watchmaker” by Richard Dawkins. Clearly the paper authors consider this to be an appropriate work of reference for the scientific background of the evolutionary process they are modelling in their software.

    So, before we get into further debate about either AVIDA, I want to be sure that we understand the same thing about a Darwinian evolutionary process. In The Blind Watchmaker, shortly after his famous "weasel" algorithm, Richard Dawkins says this on page 50, with his emphasis:
    quote:
    Although the monkey/Shakespeare model is useful for explaining the distinction between single-step selection and cumulative selection, it is misleading in various ways. One of these is that, in each generation of selective ‘breeding’, the mutant ‘progeny’ phrases were judged according to the criterion of resemblance to a distant ideal target, the phrase METHINKS IT IS LIKE A WEASEL. Life isn’t like that. Evolution has no long-term goal. There is no long distance target, no final perfection to serve as a criterion of selection, although human vanity cherishes the absurd notion that our species is the final goal of evolution. In real life, the criterion for selection is always the short-term goal of either simple survival, or more generally, reproductive success. If, after the aeons, what looks like progress towards some distant goal seems, with hindsight, to have been achieved, this is always an incidental consequence of many generations of short-term selection The watchmaker that is cumulative natural selection is blind to the future and has no long-term goal.

    So that is how Dawkins describes a Darwinian process. Natural selection has “no long distance target”. It is “blind to the future and has no long-term goal”. He does not say that there may possibly be a long-term goal behind it, but we have yet to discern it, whether using scientific tools, or indeed any other tools. No, he is very specific indeed. There is definitely no purpose to natural selection. Any form of teleology is completely out. We are an accident of nature.

    As this thread has noted many times now, we are surrounded by everyday processes that form a complex result by a process of cumulative selection in tiny incremental steps. In just 9 months a single fertilised cell grows by a cumulative stepwise process into a baby, a most impressive example of macroevolution in the most general sense of the word. But of course, an embryonic process is not a Darwinian process.

    So, before we get into further discussion about Dembski and whether natural selection can create complex specified information, my question to you is this: How do we distinguish between a Darwinian evolutionary process and a non-Darwinian one? How do we decide whether the selection we observe in a modelled evolutionary process properly models natural selection, and not some other form of selection? What are the essential determining criteria for natural selection?

    That an evolutionary algorithm won't come up with a solution the designer couldn't have found. The solution found by an evolutionary method had parts of the circuit not actually connecting to the circuit- something no human designer would come up with. (IIRC that's the reason I brought this up in the first place)

    I read this assertion the first time you posted it, but it is no more correct now than then. Firstly you are not comparing like with like. You are confusing the normal process of electronic circuit design using conventional methods with one of the key points to this experiment, which was to investigate a highly unconventional situation.

    Engineers normally utilise conventional circuit design methods because they know in advance that they will work. In this case conventional methods were excluded from the start by the explicit aim of the experiment: Was there any chip configuration at all that could achieve the desired result? At the start no one knew the answer.

    The genetic algorithm made answering the question in a reasonable time frame a practical proposition. With a search space of 10E+542 configuration possibilities, it would need a lot of human technicians and even more time to complete the experiment by a crude process of blind search, noting the results manually.

    However, what you have conspicuously failed to consider is that a crude blind search process by humans, using the same functional tests and equipment as the computer experiment, would eventually get to the same answers as the genetic algorithm. All that the computer has done is to save someone from a great deal of highly laborious lab work.

    Intelligently designed software can certainly be a very beneficial scientific tool, but then that is hardly news.

    So we have an evolved object that is irreducibly complex. Counter example presented.

    Yet more evidence that you do not understand the concept of irreducible complexity. This concept certainly does apply to some (but not all) electronic circuits, as you will know when your TV or computer dies completely due to a failed component.

    However, it is by no means applicable to all engineering systems in all circumstances, and in many cases may only apply to a distinct subset of any system. You may lose the red colour gun on your TV, but otherwise it still functions, after a fashion. But a brick through the screen will ruin your whole day. [Smile]

    The microchip and all its electronic circuit connections and connection possibilities were a given at the start of the experiment. Hence the computer was not evolving any physical objects at all. What the computer manipulated and evolved was the 1800 configuration bits required to control the chip, eventually finding a configuration that produced the required functional behaviour.

    Your argument presumes that the concept of irreducible complexity can apply to 1800 bits of computer information, but unfortunately you are seeking to apply this concept to a context where it is completely inapplicable. Here is Behe’s definition again:
    quote:
    By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.

    Information held in a computer memory has no interacting parts, well matched or otherwise, and certainly no function as a single engineering system. Hence the concept of irreducible complexity cannot possibly apply to a string of 1800 parameters held in a computer memory. The concept is irrelevant in this case.

    Counter example rebutted.

    I think my reply here will start with the fact that computers “know” things in a very different sense to the way humans “know” things. Since computers have no self-awareness, I would argue that they actually “know” nothing in a human sense – colloquial language is somewhat loose here. What they do have is access to binary data that is provided for them by humans and instructions on how to manipulate that data, also from humans.

    So I think your distinction between a computer having a fitness value “in advance” versus only “knowing” how to calculate it is a spurious one. If the computer did not know how to calculate a fitness value, it could never give us any fitness values at all. Access to the fitness values follows as a logical consequence of having access to the fitness function.

    Maybe it would be a little clearer to say that the given fitness function has defined in advance the set of all possible fitness values. As data becomes available from the experiment, the computer then calculates a fitness function value. This arithmetical calculation obtains the relevant value from the pre-existing set of all possible values.

    When a genetic algorithm is given a fitness function in the form of a mathematically continuous real equation, as in the experiment, the computer is provided at the start with some wide-ranging and highly-specified information. Without it there is simply no problem to solve.

    But note that even if we throw away the computer and revert to blind search by humans – the slowest and crudest possible search technique – humans would still need that same information about the fitness function to make any progress. With that information they would eventually reach the same solution as the computer (but with 10E+542 possible configurations I wouldn’t want to be the project manager on that job [Smile] ).

    IMO I think you are using language loosely again when you say that “the system generated the new information”. Computers do not in fact “generate” anything new in the sense of “create”. What a computer can do is to search much more efficiently than any human through a much larger range of possibilities.

    However, a computer cannot tell you anything that wasn’t first put into the computer by a human. The proof of this is simple. Take any computer. Do not give it any data or software outside the basic operating system. Ask it any question you wish (outside basic operating system parameters). I guarantee that you will get no answer.

    I also think you are using the phrase “work out (the configuration)” somewhat loosely here. I think a more accurate phrase in relation to the source of the final configuration would be “pre-existing information found through an efficient search pattern”.

    I would argue that the computer sorted through a range of possibilities, albeit in a much more efficient manner than any human, but that this range of possibilities was defined beforehand by a human. The information associated with that range of possibilities was therefore provided by a human.

    This comes back to my earlier post about the precise criteria to define a Darwinian process. Any old selection is not good enough – it must be natural selection. I hope that we are agreed on that, although I notice that you often say “selection” rather than “natural selection”. This is not mere semantics, and the difference is crucial.

    I am certainly not denying that an intelligently designed teleological selection process can deliver some impressive results, but that, by definition, is not natural selection. The article at Talk.Origins lists at least 9 different types of selection used in these algorithms. If the selection process in the algorithm imports some hidden form of teleology, then my previous comments are fully justified.

    I would like to hear your response on the specific criteria to define natural selection within a Darwinian process before I comment any further, otherwise the argument degenerates to a “yes it is, no it’s not” type of exchange.

    quote:

    I have only encountered these algorithms thanks to this thread, and they are clearly useful mathematical tools, inspired by evolutionary ideas. However, it’s fairly obvious from the article at Talk.Origins that some Darwinists do consider them to be corroborating evidence for biological Darwinism.

    But what I find amazing about this article is the way that virtually no arguments are provided to say why these algorithms bear any necessary relation to biological Darwinism, something I have already complained about on this thread. After a long, informative and mostly factual description, the article launches straight into a rebuttal of “Creationist Arguments”.

    I find this extraordinarily naïve, and evidence that metaphorical language has been misunderstood in a very literalistic fashion. The basic argument seems to be that, just because I can model an evolutionary process of some kind on a computer, that is evidence for a Darwinian evolutionary process to be true in the biological world. If there is a more sophisticated argument there, I haven’t found it yet.

    This argument can be scotched easily by reference to the computer graphics in modern films, which are highly impressive, and also highly fake. I’ve been accused of erecting a strawman several times on this thread already, unfairly in my opinion, but this is one occasion when I will be glad to have my misconceptions pointed out to me. Is there a more sophisticated argument that links these algorithms to biological Darwinism?

    quote:
    Glenn Oldham said:

    3.2.1) The argument about mathematics:

    You said on 23 June, 2004 11:31 of genetic algorithms: “I do not think that they are a model of Darwinian evolution, unless you are prepared to accept that natural selection can operate in a mathematical fashion according to intelligently determined numerical rules with a clear sense of purpose behind them.” But this has as little merit as saying that “I do not think that computer models of bridge behaviour [are] a model of real bridge behaviour, unless you are prepared to accept that bridges can operate in a mathematical fashion according to intelligently determined numerical rules with a clear sense of purpose behind them.” Physical things of all sorts obey the laws of physics and chemistry and show statistical patterns and these can be modelled, more or less well, using numbers. There is nothing special about biology that rules out computer modelling a priori.

    I am all in favour of the use of computers in biology and science generally to model and study physical behaviour. However, I am also a great believer in the aphorism “To forgive is divine, to err is human, but to really screw things up you need a computer”. [Smile]

    My highlighted comment above was very specific to genetic algorithms, as my summary of the algorithmic logic at work. The Talk.Origins article cites genetic algorithm models in all sorts of diverse fields as support for Darwinism. Either I am misreading these models badly, or Darwinists are quite mistaken in claiming them as support for their position.

    Although I intended my comment to be for genetic algorithms, I would note that it is indeed also applicable to bridge models, especially during the construction stage when bridges change regularly, and are arguably at their most vulnerable. The design of the construction sequence is frequently a crucial stage for a major bridge.

    One of the reasons I am jumping all over these particular models is that my professional work has involved me in critiquing computer models in relation to structural integrity and nuclear safety issues. If I told the vetting authorities, “Nuclear power is safe, the computer model says so”, I would be justifiably asked (and indeed have been) to demonstrate how realistic my model was, before my word would be accepted.

    The computer model needs to be an accurate reflection of physical reality. Even then, any model is only ever as good as the assumptions and data in it. “Garbage in equals garbage out” is as true as ever. Even a good model delivering reliable results can be misinterpreted by a fallible human, or misused by a perverse one. Humans are always the weak link in the chain, since the buck stops with us.

    Oops, another cross post Neil,
    Neil,
    I have been laid up so sorry for the delay in continuing my earlier post about the genetic algorithms:

    I was on section 3) Do these examples differ so much from natural selection that they have no evidential value for Darwinism?

    And I had got to the bit about the points you have raised regarding things like the fitness function, mutations, constraint. These differences do limit the extent of the conclusions that can be drawn from the algorithms, but they don’t render them worthless as support for neo-Darwinism.

    3.2.2) Points about fitness.
    3.2.1) Unfitness One of your comments on the chip experiment was “I consider that this is an example of unconstrained evolution, starting with an completely unfit (i.e. dead or unsuccessfully breeding) life-form and passing through many unfit stages (but still breeding), until the numbers enter a region where the fitness function starts giving desirable answers”

    This is to misunderstand fitness. The experiment can be seen as modelling the case of a trait or function that is advantageous to the organism but lack of which does not prevent the organism from living and reproducing. It just makes it less fit than its fellows that possess the trait. An example would be a rabbit like animal that ran in a straight line from its predator compared with one that ran but also zigzagged. The latter strategy may be more successful and a rabbits showing that trait would, on average, survive to breed more successfully than those that did not. But those that ran straight would not thereby all die. The experiment could be seen as analogous to that kind of case. There would be no problem at all with the population showing no evidence of zigzag running either initially or for generations. Once the trait starts to appear though selection can get going. (See also 3.4)

    3.2.2) The fitness function I have already dealt with some of your comments on the fitness function. To address your most recent in your post of 18 July, 2004 16:28 where you appear to have been, at best, misled, by kens unfortunately loose wording. You quoted ken as saying: “In real life biological fitness isn't a function. It's a count - the number of descendents something has. And it is of course contingent, historical. The continuously variable fitness numbers used in models are just that, models. And deterministic equations are very bad models of evolutionary or ecological processes. Stochastic ones better, but individual-based modelling better still.” Then you then said:

    quote:
    let’s look more closely at how the experiment operated … it assigned a fitness value to each individual in each generation by reference to equation 1 in the paper. This equation incorporates all the information necessary to specify the final end point, the goal of the process. … In the light of these comments For each individual an absolute fitness was established by constant reference to this desired end goal. ... these algorithms have access to an “ideal” at all times – the specified end goal. … . these algorithms, by definition, cannot be a truly Darwinian process. They are driven throughout by a goal-oriented methodology,
    It is a mistake to deny (as ken seems to do) the link between fitness and function. Darwinism depends on the view that some variations are genuinely, physically, advantageous to the organism. They don’t get to breed more than others just by chance but because the variation makes them more capable of doing something that promotes their breeding than their fellows and THAT increases their chances of breeding. The equation in this experiment was used to determine which of current configurations in any generation was performing the functions most nearly correctly. It compared what they were doing with what they were ideally intended to do. There is nothing inherently problematic with this. Lots of fitness in the wild could be assessed in this way. Which rabbits run most in a zigzag fashion? Or which animal has the more opposable thumb, and so on. (From the informational point of view it is crucial to be clear that the equation did not compare how they were doing it with how it would finally be done, by the way - it is NOT true to say that “This equation incorporates all the information necessary to specify the final end point” in the sense of it being able to specify the final configuration.)

    quote:
    these algorithms are not modelling natural selection as understood within Darwinism. In them the selection process means “nearer to the specified target”, not “who has the most grandchildren”. The experiment is not counting the descendants, and then deducing a theory from that empirical data. Instead it imposes a deterministic form of differential breeding in a pre-determined manner.
    What ken said has again misled you here. Selection operates by, on average, ensuring that those offspring with the advantageous variation breed more than those without. A selection process that selected to breed those individuals that had the most grandchildren would not be able to start, or would be viciously circular, since who has the most grandchildren depends on who is selected to breed.

    quote:
    My third point is that this whole experiment was functionally deterministic, not stochastic. If the experiment was run again, it would converge to the same functional target. It is not free to do anything else. A true stochastic process would be free to give a different result and converge to some other functional target.
    The stochastic character of evolution is that chance enters into whether an organism gets to breed and not just whether or not it has an advantageous variation. There was some element of the stochastic in the experiment in that some of the less well-adapted individuals got to breed as well. I do not see that making the process more stochastic would alter the final outcome. Selection would still be operating in the direction of the function chosen. It might well take a different route and take longer to get there, but the change would be in the direction of improved matching to the function. Incidentally, if the experiment was run again there is no guarantee that the same final configuration would be arrived at. There may be many such configurations for all we know.

    3.3) Mutations You made a number of remarks about deleterious mutations not being allowed suggesting that the individuals were unkillable and so on. Well, deleterious mutations were allowed but, of course, did not get to breed because their fitness was therefore less than the others. (see also 3.4)

    3.4) What is mutating? ‘What is mutating?’ are not your words but mine to pick out a question that incorporates one of your points about fitness and about mutation. You may have felt my 3.2.1 was overlooked something. Once the genotype for the trait shows some degree of fitness then selection can get going, fair enough. But what happens prior to that? If, in the early stages of the experiment no fitness was shown by the individuals there may have been some generations where the genotype of the individuals was varying in an unconstrained fashion. Could this happen in real life? What is mutating, exactly, and how unconstrained can it be in how much it mutates? Surely you can’t have unconstrained mutation that does not make the organism unfit?

    Well, this is where things like gene transposition and gene duplication can get going. In gene duplication for example, a gene for a particular protein duplicates. If one of the genes then mutates then even if its own functionality is compromised it may have no deleterious effect on the organism because the other genes operation is unimpaired. The duplicate gene may then mutate further with comparatively little constraint. If it then changes so that it acquires a mildly beneficial function then selection can begin to operate on it.

    This is not an ad-hoc face saving explanation since we have compelling grounds, from DNA sequencing, for believing gene duplication and transposition (and indeed chromosome duplication) to have been a major feature of evolutionary history.

    Conclusion
    The chip experiment does model the Darwinian selection of an advantageous trait although it has limitations. It does, however, show that a system that combines variation, selection, reproduction and inheritance – the essential features of natural selection – can evolve and improve a function. It is a particularly nice aspect of this experiment, as opposed to other algorithms, that it did not have the final configuration specified in advance as its target. Instead only the function was specified, NOT the configuration that it must use to get it. Indeed non-one knows if the final configuration is the only configuration that would work.

    You asked a question (which turned out to be three!)

    quote:
    Originally posted by Faithful Sheepdog:
    So, before we get into further discussion about Dembski and whether natural selection can create complex specified information, my question [singular!] to you is this:

    [1] How do we distinguish between
    · a Darwinian evolutionary process and
    · a non-Darwinian one?

    [2] How do we decide whether the selection we observe in a modelled evolutionary process properly models
    · natural selection, and not
    · some other form of selection?

    [3] What are the essential determining criteria for natural selection?

    The key elements of Darwinian selection are variation, selection, reproduction, and inheritance (these last two are often just called ‘replication’). So we have:

    1) Variation within a population of entities. The cause of the variation is a random process. It needs to be noted that ‘random’ here does not mean ‘completely without pattern or limit or constraints’. It just means that the cause of the variation is random with respect to whether the variation is advantageous to the entity or not. There are obviously going to be physical and chemical limits and tendencies involved in the way in which variation can arise. The contrast here is with the variation proposed in Lamarckian evolution which is automatically advantageous, for example where the striving of the animal for leaves on higher branches supposedly gives it a longer neck than it inherited. Without variation there would be nothing for selection to ‘choose’ between. If all individuals in a population are identical for a particular trait then natural selection on that trait cannot occur.

    2) Selection that is non-random. This simply means that some variations give the individual entities that possess them an advantage (or advantages) over their fellows by enabling them to produce more offspring, on average, than those individuals that do not possess one of those variations.

    3) Reproduction. This just means that there must be individuals in the population that reproduce. If there is no reproduction then the cycle cannot repeat and the change lasts one generation only.

    4) Inheritance. The advantageous variation must be heritable. If the variation is not heritable then it is lost and future generations are unable to benefit from it or natural selection build further variation on it. The heritability need not be 100% but if the heritability is too low then the variation is more likely to be lost.

    Any selective process that incorporates these elements or analogues of them deserves to be called a Darwinian selection process.

    It is because so many of the evolutionary algorithms DO incorporate these elements that they can lay claim to modelling Darwinian selection. Clearly, the more it can include other relevant variables from nature then the better it can model natural selection. For example, having different types of creature competing with each other for resources. This means that the fitness criterion for one organism will change even more over time if the other species it competes with is evolving and presenting new challenges.) The limits to the models limit the evidential support that they offer to neo-Darwinism but do not invalidate that evidence.

    One rhetorical tactic popular with some anti-Darwinian’s is to say of a piece of evidence that if it is not proof then it is not evidence. That is fallacious. Just because a piece of evidence does not conclusively establish the truth of the conclusion does not mean it is of no evidential importance at all. The case for neo-Darwinian evolution is a cumulative case and these algorithms add to that cumulative case. Insofar as someone considers that case to be fatally flawed in other areas not related to selection then these algorithms are unlikely to persuade them.

    Philip Johnson is charged by Nancy Murphey with this kind of illogic. One theory of the origin of life for example says that organic molecules could be formed in the primordial environment by ordinary chemical reactions in certain conditions. They replicate what they think the conditions were, including artificial lightning etc and organic molecules are formed. Philip Johnson then argues that because the experiment did not create life, is not an instance of the creation of life then it provides NO reason to believe the theory. But this is nonsense. It does not prove the theory but it provides support for one part of it. It is certainly not irrelevant data that can responsibly be ignored!

    Likewise with genetic algorithms. Even though they are not instances of natural selection and so do not conclusively prove evolution by natural selection they do provide confirmatory support that the proposed mechanism for natural selection may be correct.

    Glenn, I will reply to your latest post in due course, but that may be later today (Thursday) or even tomorrow. To avoid any more cross-posting I suggest that you wait until then if you wish to reply further.

    In the meantime here is a brilliant example of irreducible complexity in action. You'll need Flash 6 and the picture is a little dark on my screen, but otherwise it is a perfect example. One tiny component out of place and the system would not work at all.

    [Hot and Hormonal] apologies, ken, so you were. I took it from the context in which Neil quoted you that you were referring to function as physical capacity/fitness, so either Neil misunderstood you or I misunderstood Neil (or both even).

    Noted, Neil, but I will just add the following on a part of the topic on which you have posted the most recent response.

    Neil, one issue we have been discussing is the question of whether or not new complex specified information was created in the chip experiment and what or who created or provided that information. This is relevant to the debate about Intelligent Design because some IDers (such as Dembski) deny that either natural selection or genetic algorithms can generate new ‘complex specified information’ (to use Dembski’s term).

    I argued that the complex specified information was indeed new and that it had been generated by the system and not provided by the human designers of the system. In response you said (with bits snipped as indicated by ellipses):

    quote:
    Originally posted by Faithful Sheepdog:
    I would argue that they [computers] actually “know” nothing in a human sense … What they do have is access to binary data that is provided for them by humans and instructions on how to manipulate that data, also from humans.

    So I think your distinction between a computer having a fitness value “in advance” versus only “knowing” how to calculate it is a spurious one. … Access to the fitness values follows as a logical consequence of having access to the fitness function.

    … the given fitness function has defined in advance the set of all possible fitness values. As data becomes available from the experiment, the computer then calculates a fitness function value. This arithmetical calculation obtains the relevant value from the pre-existing set of all possible values.

    When a genetic algorithm is given a fitness function in the form of a mathematically continuous real equation, as in the experiment, the computer is provided at the start with some wide-ranging and highly-specified information.

    IMO I think you are using language loosely again when you say that “the system generated the new information”. Computers do not in fact “generate” anything new in the sense of “create”. What a computer can do is to search much more efficiently than any human through a much larger range of possibilities.

    However, a computer cannot tell you anything that wasn’t first put into the computer by a human.

    I also think you are using the phrase “work out (the configuration)” somewhat loosely here. I think a more accurate phrase in relation to the source of the final configuration would be “pre-existing information found through an efficient search pattern”.

    I would argue that the computer sorted through a range of possibilities, albeit in a much more efficient manner than any human, but that this range of possibilities was defined beforehand by a human. The information associated with that range of possibilities was therefore provided by a human.

    First of all there is a very definite and precise piece of information whose origin we are discussing here. That piece of information is that which represents or describes the exact configuration of the chip in the experiment at the point near the end when it became perfectly functional call this information ‘X’. This information, X, that specifies that configuration is 1800 bits in quantity. Information can exist in a variety of forms and be encoded in a variety of ways (it could be written, a diagram, a physical model, magnetic blips on a disc, the configuration of the chip itself and so on). At the end of the experiment the information X was present in the system in at least two copies. Firstly, as the configuration of the chip itself and, secondly, in the memory of the computer which had just used that information to configure the chip in that pattern. The computer had just taken a very similar 1800 bit piece of memory and mutated it randomly to yield what turned out to be X the final configuration. In the computers memory the information X was probably a sequence of 0’s and 1’s 1800 digits long as magnetic blips or however such information is physically stored.

    My contention is pretty simple, it is that:


    It is, therefore, false to say that the information X was provided by humans in the sense that they put X into the system. They did not because there was no copy of X entered into the system (and in this case the humans did not even possess a copy of X).

    This is an important point and an important distinction because to hear some ID advocates talk you would imagine that that is exactly how they think that God does provide what they see as certain essential information to organisms that natural selection cannot otherwise acquire. This experiment shows that the provision of information in that direct way is NOT required for a Darwinian type of selection process to arrive at new complex specified information. Whether it is needed for certain types of allegedly supercomplex information such as for irreducibly complex systems is another question. What I am attacking here is the view that natural selection cannot arrive at complex specified information under any circumstances, without it being inserted into the system by a designer.

    You say that:
    quote:
    ” a more accurate phrase in relation to the source of the final configuration would be “pre-existing information found through an efficient search pattern”.”
    But this is inaccurate. Information X was NOT ‘pre-existent’ in the information provided to the system. NEITHER was information X found by a search amongst ’ the pre-existing set of all possible values’ since there was never a complete set of such values in the computer at any time. As a comparison if I ask my calculator to tell me what 158,791 multiplied by 884,672 is it does not look up the answer on an internal table that lists the results of the multiplication of every possible set of two numbers (within some huge range). Instead, it calculates it using a basic set of repetitive instructions and says: 140,477,951,552. It is, therefore NOT literally true to say, as you do, that, “a computer cannot tell you anything that wasn’t first put into the computer by a human”. No-one put in 140,477,951,552 into my computer.

    The actual information that the computer was provided with was, as you say, “wide-ranging and highly-specified information” and was “binary data … provided … by humans and instructions on how to manipulate that data, also from humans.” Indeed so, but it was not given the range of possible configurations in the form 0, 1, 10, 11, 100, 101, 111, 1000, all the way through to 1 followed by 1800 zeros. It is much more economical of information to tell the computer something like ‘the range of possible configurations is represented by a string of binary digits 1800 digits long where any digit can be 0 or 1’. This will take a lot of code, but less than listing the roughly 10 to the power 541 numbers individually. So, again, the computer was not provided with the number X that represented the final solution.

    And, as you say, it is certainly true that “Access to the fitness values follows as a logical consequence of having access to the fitness function.” Yes, the computer had clear instructions how to calculate (or set up and measure in this case) the fitness values i.e. how well any given configuration performed its function. But having access to those fitness values does not mean that those fitness values were physically present in the computer. No copy of X was lying around in the memory or elsewhere in the system to be ‘accessed’.

    So the humans did NOT provide the computer with the information X. BUT, you may protest, they did provide it with all the information it needed to arrive at X after a suitable series of search operations involving replication variation and selection. (I understand that this may be what Dembski confusingly and misleadingly describes as ‘front loading of information’.) I have no objection at all to saying that information X as a solution to the problem of performing the required function was inherent in the parameters and physical constraints of the system. But as I have pointed out before that is NOT in any way an anti-Darwinian view. A Darwinian is happy to agree that the adaptations and organisms that have arisen in nature are the results of the parts of the system at a variety of levels (molecular, cellular, organismal, etc) interacting in accord with laws of physics and chemistry and so on and that replication, variation, and selection operates wherever the conditions for it in the system are right.

    The question of where the system comes from and whether it is designed is a separate question. Here I am simply looking at one argument against natural selection. If the system has a designer then evolution by natural selection can be seen as Intelligent Design. If the system has not got a designer then it cannot.

    And I had got to the bit about the points you have raised regarding things like the fitness function, mutations, constraint. These differences do limit the extent of the conclusions that can be drawn from the algorithms, but they don’t render them worthless as support for neo-Darwinism.

    My overall point with respect to genetic algorithms is that it is up to Darwinists to demonstrate the relevance of these particular computer techniques to actual biological processes, especially in the light of our now much enhanced knowledge of the biochemistry of genes and genetic functions. Talk.Origins is exceptionally bad in this regard, taking a huge amount for granted.

    Genes are far more sophisticated things than simply a string of binary data in a computer. Yes, they contain information, but they do not act in the same way as a string of binary data in a computer. These differences are crucial to the true relevance of any computer models. Furthermore, as Richard Dawkins puts it on page 60 of “The Blind Watchmaker”:
    quote:
    But natural selection doesn’t choose genes directly, it chooses the effects that genes have on bodies, technically called phenotypic effects.
    So there is the whole question of the genotype/phenotype distinction. There is no doubt in my mind that conventional genetic algorithms are selecting at the level of genes, and not phenotypes. These algorithms have no concept of a body or phenotypic effects within them. The fitness function acts directly on a string of binary data, metaphorically referred to as “genes”, but acting very differently to real genes.

    So I would argue that there is in fact a major difference between these models and the biological facts, and in consequence they do not properly reflect Darwinian theory either. This conflation of genes with phenotypes appears in your post when you say:

    quote:
    This is to misunderstand fitness. The experiment can be seen as modelling the case of a trait or function that is advantageous to the organism but lack of which does not prevent the organism from living and reproducing. It just makes it less fit than its fellows that possess the trait. An example would be a rabbit like animal that ran in a straight line from its predator compared with one that ran but also zigzagged.

    I think I’ve said enough about genetic algorithms for now. From what I can see the AVIDA programme is indeed a step in the right direction. It is certainly very different to the genetic algorithms we have been discussing. I am still trying to get my head round it, so I won’t comment on it any further.

    From here on I will respond to your comments on the subject of fitness and mutation (21 July, 2004 16:46) and natural selection within a Darwinian process (22 July, 2004 10:20). To keep this post within limits I will only quote small fragments from your posts as necessary, but rest assured, they have been printed out and studied in full.

    THE CONCEPT OF “FITNESS”

    I will begin by noting that in “The Blind Watchmaker” the word fitness (or even unfitness) does not appear in the index at all. As a concept it would appear to have no use for Richard Dawkins. This would tally with what I have heard of Darwin himself, who apparently never used the phrase “survival of the fittest”. He spoke of “useful variants” or “usefulness”. You use the word “advantageous”.

    Whilst the concept is of usefulness or fitness would appear to be intuitively obvious, it is impossible to measure them independently of actual survival and reproduction, without ending up in a hopeless tautology. That is why Ken spoke of fitness in terms of counting numbers rather than any form of [mathematical] function. Here are his words again with one edit of mine:
    quote:
    In real life biological fitness isn't a [mathematical] function. It's a count - the number of descendents something has. And it is of course contingent, historical. The continuously variable fitness numbers used in models are just that, models. And deterministic equations are very bad models of evolutionary or ecological processes. Stochastic ones better, but individual-based modelling better still.

    I do not think it was misleading of him to speak in this way. All we can hope to measure is differential survival. I am certainly happy to accept that in any given generation in any population, there will be variations between individuals – for any and every reason – better hunter of food, better defences against predators, better resistance to disease, etc.

    If we define the reproductive success x as the number of offspring per individual, then there is certainly no reason for x to be constant throughout the population. x may be distributed in all sorts of ways, as it is in human mothers.

    However, I do not think there is any way in which x can be directly measured at a given moment. We can only determine the value of x for an earlier generation by a count of the later offspring. Its value only becomes clear in retrospect, assuming that we are monitoring data. This is certainly how Kettlewell did his famous peppered moth research (but note in fact that he counted the parental survivors rather then the offspring).

    This contrasts completely with a conventional genetic algorithm, where each generation has access directly to the relevant x value before the generation “gives birth” numerically. You speak truer than you think when you say:
    quote:
    A selection process that selected to breed those individuals that had the most grandchildren would not be able to start, or would be viciously circular, since who has the most grandchildren depends on who is selected to breed.

    The only way to break out of this circularity in a genetic algorithm is to impose onto the algorithm a concept of fitness – the fitness function - that can be clearly distinguished from subsequent reproductive success (x). Reproductive success can then be linked to this separate concept of fitness in any manner that we choose. And that is certainly what the electronics experiment has done from here..
    quote:
    After evaluation of each individual on the real FPGA, the next generation was formed by first copying over the single fittest individual unchanged (elitism); the remaining 49 members were derived from parents chosen through linear rank-based selection, in which the fittest individual of the current generation had an expectation of twice as many offspring as the median-ranked individual.

    As a numerical experiment it is of course perfectly acceptable to postulate all sorts of figures and scenarios for reproductive success (x) in relation to the fitness function, but it is at precisely this point that the algorithm has broken away from the real world of biology, where we simply cannot measure fitness in a given population directly and do not have access to the reproductive success (x) until a much later time.

    By giving the computer access to this privileged information, we have a Deus ex machina driving the answers in a certain predetermined way as a starting assumption. IMO this invalidates any appeal to the success of the algorithmic methodology as necessarily demonstrating anything in biology.


    MUTATION

    I won’t say much on this subject. Paradoxically I threw in my comment on mutation rates as a response to a comment from Rex Monday who said, with my emphasis:
    quote:
    So, the problem you propose that the model may not address doesn't exist, and the lack of correspondence between the model and nature doesn't exist either. (there are plenty of other lacks: it is, like Camelot, only a model.

    The electronics experiment was not set up specifically to model a biological process – it was to investigate electronic possibilities using a certain algorithmic approach. It is now being discussed as biological evidence only in a secondary and derivative fashion. It is therefore unfair of me to critique it on the subject of mutation rates.

    It is my understanding that, in the mathematics of evolutionary genetics, excessive mutation rates are deleterious to the species as a whole, resulting in an “error catastrophe”, but this is something I need to investigate further. Let’s not forget that the vast majority of observed mutations in nature are highly deleterious. Very few – the raw material for Darwinism - are beneficial (see pages 306-307 of TBW).

    Incidentally, the average mutation rate in the electronics experiment was 2.7 [bits] per genotype [of 1800 bits], not 2.7% (i.e. percent) as quoted by Justinian above. 2.7 bits is 0.15% of an 1800-bit genotype, a much lower figure.


    NATURAL SELECTION

    Firstly we have the definition that you give (which again, I note, simply says “selection”, not “natural selection”:

    quote:
    Selection that is non-random. This simply means that some variations give the individual entities that possess them an advantage (or advantages) over their fellows by enabling them to produce more offspring, on average, than those individuals that do not possess one of those variations.

    Bearing in mind my earlier comments on the profound difficulties with the definition of “advantage” or phenotype fitness (as opposed to Ken’s concept of counting survival numbers), here is how American neo-Darwinian geneticist John Endler in his book “Natural Selection in the Wild” sets up a syllogism for his understanding of natural selection:

    quote:

    If, within a species or population, the individuals:

    a) vary in some attribute or trait q (physiological, morphological, or behavioural) – the condition of variation;

    b) leave different numbers of offspring in consistent relationship to the presence or absence of trait q – the condition of selection differences;

    c) transmit the trait q faithfully between parents and offspring – the condition of heredity;

    d) then the frequency of trait q will differ predictably between the population of all parents and the population of all offspring.

    (This is quoted in the July/August 1999 edition of Touchstone Magazine in an article by Paul Nelson entitled “Unfit for Survival: The Fatal Flaws of Natural Selection” – unfortunately I can’t link to this article. However, this edition has also now been published as a book called “Signs of Intelligence”, edited by William Dembski and James Kushiner, published by Brazos Press 2001, available from ARN here.)

    So, under Endler’s formulation, we must demonstrate that conditions a), b) and c) are all satisfied, before we can infer consequence d), i.e. that any variation in the frequency of trait q in the offspring relative to the parents is due to “natural selection”. Note that this syllogism avoids any form of circularity or tautology by rigorously excluding any consideration of “the quality of the phenotype”.

    According to Nelson’s interpretation of Endler, natural selection is “simply a directional shift in the trait frequencies of species”, and no more. Endler therefore agrees with Ken that natural selection is about natural history, not natural philosophy. It is descriptive, not prescriptive. It is a statistical statement, not a “mechanistic, causal account” (Dawkins).

    Nelson quotes Endler (who is a neo-Darwinist) as follows:
    quote:
    To say that a new adaptation necessarily arose through natural selection is an incomplete description, a tautology, and a misrepresentation of natural selection, adaptation and evolution.
    In comparison with this, we have already seen how Richard Dawkins describes natural selection on page 50 of The Blind Watchmaker:
    quote:
    Evolution has no long-term goal. There is no long distance target, no final perfection to serve as a criterion of selection, although human vanity cherishes the absurd notion that our species is the final goal of evolution. In real life, the criterion for selection is always the short-term goal of either simple survival, or more generally, reproductive success. If, after the aeons, what looks like progress towards some distant goal seems, with hindsight, to have been achieved, this is always an incidental consequence of many generations of short-term selection The watchmaker that is cumulative natural selection is blind to the future and has no long-term goal.

    and Dawkins goes on to say on pages 61 and 62 of “The Blind Watchmaker”, immediately after the section on biomorphs:
    quote:
    But this isn’t getting us any closer to simulating natural selection. The important point is that nature doesn’t need computing power in order to select, except in special cases like peahens choosing peacocks. In nature the usual selecting agent is direct, stark and simple. It is the grim reaper. Of course the reasons for survival are anything but simple – that is why natural selection can build up animals and plants of such formidable complexity. But there is something very crude and simple about death itself. And non-random death is all it takes to select phenotypes, and hence the genes they contain, in nature.

    These appear to be the sole references to the definition of natural selection in “The Blind Watchmaker”, but then he may have returned to the subject in his other writings (which I do not have). So we have natural selection as “simple survival”, “reproductive success” and “non-random death”. Dawkins gives us no further information, nor does he define what he means by non-random death. I notice that you use the phrase “non-random” too.


    DARWINIAN PROCESSES

    A deterministic process governed by natural law (such as gravity) is certainly non-random, but I very much doubt that this is what Dawkins means here. On the other hand, certain kinds of non-deterministic (i.e. stochastic) processes can be termed non-random, since they can be quantified accurately in terms of statistical properties which can be measured with consistency (wave action and wind turbulence come to mind from engineering).

    This data can be used to predict future outcomes. We cannot say precisely what the wave height or wind turbulence will be, but we can cite probability bounds for them lying within a certain range under certain circumstances. Quantum mechanics in atomic physics operates similarly. But again I doubt that this is what he means.

    So once again Dawkins is loose in his language. If he is using the word non-random in a special sense, then he needs to explain exactly how he is using it. Since you use the phrase as well, in what sense are you using non-random? Can you explain it any further?

    Whatever is meant by non-random, it is clear that for Dawkins a teleological process of any kind would be completely unacceptable. This is the main basis for my many comments on the non-Darwinian nature of genetic algorithms. I sniff out a hint of teleology and shout “foul”, citing Dawkins as my authority:

    quote:
    Evolution has no long-term goal. There is no long distance target,…(TBW, page 50)

    All I would insist on is that these respects [i.e. the non-random nature of mutations] do not include anything equivalent to anticipation of what would make life better for the animal (TBW, page 306, his emphasis)

    I am beginning to suspect that one of the reasons for our lack of agreement on whether genetic algorithms can be considered a Darwinian process is our difference in understanding over exactly what natural selection is. Given the central role of natural selection in Darwinism, and the huge creative power assigned to this mechanism by Dawkins, “[it] can build up animals and plants of such formidable complexity” (TBW, page 62), I think I need a much better understanding. But is one available?

    At the moment the definition is so vague that it can include not only all 9 types of selection in the genetic algorithms discussed at Talk.Origins, but just about any other type of deterministic or stochastic selection one cares to name, provided that it is “non-random”, whether teleological or otherwise.

    I’m certain that Dawkins does not have any teleology of any kind in mind by natural selection. But is that consistent with neo-Darwinism as a whole, or even your own perspective? If there are no excluded forms of non-random selection, then this leaves the door wide open to a teleological form of selection and the brand of Intelligent Design that has much in common with a theistic form of Darwinism.

    So, as a discussion starter, is there any form of non-random selection that is not natural selection? And if it’s not, why is it not?

    In the quote from Dawkins "non-random death" clearly means that the chance of dying is associated with some other character(s) of the organism. So if you know whether or not the organism has such-and-such a character or not you can make better predictions as to whether it will die before reproducing or not.

    I think that is a more, not less, rigorous statement than the one y9ou quote earlier:

    quote:

    b) leave different numbers of offspring in consistent relationship to the presence or absence of trait
    [...]

    d) then the frequency of trait q will differ predictably between the population of all parents and the population of all offspring.

    which perhaps goes to far in using the words "consistent" and "predictably".

    This is in response to Glenn Oldham’s post at 23 July, 2004 10:09

    quote:
    Glenn Oldham said:
    First of all there is a very definite and precise piece of information whose origin we are discussing here. That piece of information is that which represents or describes the exact configuration of the chip in the experiment at the point near the end when it became perfectly functional call this information ‘X’. This information, X, that specifies that configuration is 1800 bits in quantity.

    <snip>

    The computer had just taken a very similar 1800 bit piece of memory and mutated it randomly to yield what turned out to be X the final configuration. In the computers memory the information X was probably a sequence of 0’s and 1’s 1800 digits long as magnetic blips or however such information is physically stored.


    My contention is pretty simple, it is that:

    1) X did NOT exist before that final step of the experiment either in the computer or on the chip or in the minds of the designers;

    2) In other words, there was NO physical copy of X in existence before the final step of the experiment.

    3) (It is possible that, by a freak of chance, amongst the trillions of binary digits represented on the computers discs and which make up the computers general software there might have been a string of 1800 digits identical to X (somewhere in the Solitaire or Word program, say). However, the presence of that X would NOT be the cause of X appearing as the final configuration. )

    I think there is some danger that we are now using the word information in various nuanced ways and arguing past each other. Looking back over my recent comments I can see places where I could have tightened up in places on my usage of the word information – I’ll come back to this in due course. It is an awkward term to define with full mathematical and philosophical precision, especially in Dembski’s usage.

    Note also that each and every configuration of the chip is associated with 1800 bits of information, whether it delivers the required functionality or not. There is no informational difference between perfect functionality and none at all, they all contain 1800 bits. However, achieving the chosen functionality made a huge difference to the researchers and was the whole purpose of he experiment – teleology again!

    Since the functional specification certainly did exist in the minds of the minds of the designers before the start of the experiment, your comment in 1) above cannot be sustained. Without the information of this target functionality, the experiment would have gone nowhere. But of course, they didn’t know the right configuration at that stage, or even whether one was possible.

    A specified function was how the experiment was set up, and so the specified function is intimately associated with Dembski’s notion of complex specified information (CSI). By specifying one function they ruled out a huge number of others. Therefore there is a large informational content associated with that function – in this case 1800 bits.

    quote:
    Glenn Oldham said:
    It is, therefore, false to say that the information X was provided by humans in the sense that they put X into the system. They did not because there was no copy of X entered into the system (and in this case the humans did not even possess a copy of X)

    <snip>

    This experiment shows that the provision of information in that direct way is NOT required for a Darwinian type of selection process to arrive at new complex specified information.

    <snip>

    What I am attacking here is the view that natural selection cannot arrive at complex specified information under any circumstances, without it being inserted into the system by a designer.

    I can’t see that this conclusion is correct at all on the basis of the electronics experiment. You seem to think that providing the required functionality and the fitness function is not providing information in a direct way. I must disagree completely.

    Dembski has attempted to use some general mathematical theorems regarding complex specified information (No Free Lunch), but for now I won’t go there – it’s too complex for me. I’ll concentrate instead on some details of the experiment, which are adequate for my purpose. At the beginning we have the following as givens:

    1. The configurable microchip with 10E+542 possible configuration states
    2. The computer programmed with a genetic algorithm, the fitness function equation and all associated software.
    3. All ancillary equipment such as the analogue integrator, connections to the computer etc.
    4. A target functionality, defined fully in the form of a mathematically continuous fitness function.

    The experiment had two aims:

    1. Could any configuration achieve the specified function (this was not a given)?
    2. If so, what were the best configurations for delivering the specified function?

    At this stage the experiment in principle was no different qualitatively to many others in the physical sciences where we test certain hardware to see if it can achieve a certain function, and how well it achieves that function. At the start we are ignorant of these facts, but we expect to learn something through the experiment. Full size or scale model load tests in engineering are a case in point.

    The only significant difference in the present case was a quantitative one: There were 10E+542 possible states to investigate – a huge number. Could any configuration deliver the required function, especially since it was such an unusual one for such a chip? The experiment was set up to find out.

    It’s important to note that the functional abilities of the chip were governed by the laws of physics. This included the various configuration states which were designed and built in to the chip. So at the start of the experiment the set of all possible physical functions delivered by the chip was in existence and was constrained by:

    1. The laws of physics
    2. The properties of the chip
    3. The functional possibilities associated with each of the 10E+542 configuration states.

    I emphasise: they began with a finite set of functional possibilities as a given. Each configuration state of the chip had a functional possibility of some kind. The fact that humans did not have knowledge of all these functional possibilities did not invalidate the fact that these possibilities existed. The problem was not to create the functional possibilities from scratch, or even to find all the possibilities, but rather to search the finite set of possibilities for the function they had specified.


    GENETIC ALGORITHM SEARCH

    In the genetic algorithm the first generation of 50 “genes” was generated randomly, each 1800 bits long, using a human programmed random number generator. So at this point they actually gave the computer 50 times 1800 bits of information. They set the algorithm running and it found the specified functionality in 2 to 3 weeks.

    But now what has changed? At the end all 50 “genes” had the human specified functionality, but they still only had an information content of 1800 bits each (though not necessarily the same configuration). So the algorithm began with 50 times 1800 bits of information given to the computer, and ended with 50 times 1800 bits of information.

    Hence there had been no change in the amount of information within the computer at all. Although the configuration bits were constantly changing in the genetic algorithm, there has been no increase in the amount of information present. You come close to agreeing with me here when you say:
    quote:
    The computer had just taken a very similar 1800 bit piece of memory and mutated it randomly to yield what turned out to be X the final configuration.
    But from this point our views diverge, and we disagree. I think fundamentally you are confusing “systematic change of given information following an algorithmic formulation” with “creation of new information”.


    CRUDE BLIND SEARCH

    As another proof that no new information is created by the genetic algorithm process, consider the possibility of leaving aside the genetic algorithm, and doing instead a crude blind search by computer. This would still be much faster that a human could do it, but still impossibly slow and inefficient. It is also possible in principle to do the search without a computer, since the time factor does not obviate my conclusions.

    So we pick any configuration to start with, giving the computer 1800 bits of information picked at random, and we begin a crude blind search, one configuration at a time. We plough laboriously through the configuration states, one at a time, knowing that we will get there in the end.

    In this way we would eventually stumble upon a successful configuration. (We and the whole universe may be dead and gone by then, but that’s irrelevant for now. [Smile] ) When we do find the required functionality, we will do so with 1800 bits of information, no more and no less. Once again, this process has not changed the amount of information in the computer.


    CONCLUSION

    There is no change in the amount of information in the computer whether using a genetic algorithm or pure blind search. Therefore no new information is created by either of these two processes.


    So when I said earlier on, as you quote me:
    quote:
    a more accurate phrase in relation to the source of the final configuration would be “pre-existing information found through an efficient search pattern”.
    you replied:

    quote:
    But this is inaccurate. Information X was NOT ‘pre-existent’ in the information provided to the system. NEITHER was information X found by a search amongst ’ the pre-existing set of all possible values’ since there was never a complete set of such values in the computer at any time.
    Here I must disagree. Configuration information X (if it exists at all) is completely consequent to the specification of the required functionality. I was not inaccurate to use the phrase “pre-existing information”, but it would have been even more accurate if I had said “pre-existing specified functionality”. That functionality was given by the laws of physics in combination with the properties of the chip. As a concept it existed whether we had conscious access to it or not.

    quote:
    Glenn Oldham said:
    I have no objection at all to saying that information X as a solution to the problem of performing the required function was inherent in the parameters and physical constraints of the system. But as I have pointed out before that is NOT in any way an anti-Darwinian view. A Darwinian is happy to agree that the adaptations and organisms that have arisen in nature are the results of the parts of the system at a variety of levels (molecular, cellular, organismal, etc) interacting in accord with laws of physics and chemistry and so on and that replication, variation, and selection operates wherever the conditions for it in the system are right.

    Giving the computer information in the form of continuous mathematical functions and the ability to perform arithmetical operations using those functions is a significantly higher-order provision of information that a large list of numbers. This, of course, is another sign of intelligence. The number 140,477,951,552 may never have appeared on your calculator before, but it has had the ability to access it all along through its physical design and its algorithms for arithmetical operations.

    To say that the up-front provision of information in this experiment was only “inherent” is to say far too little. There was a full and rich provision of information at the start, without which the experiment would have definitely failed. The only unknown was whether the chip could actually perform the function that was asked of it, and that ignorance is common to many experiments.

    I agree with Dembski’s concept of the “front loading of information”, but I would be interested to hear more of why you consider it “confusing and misleading”. Is your disagreement on scientific grounds, philosophical, theological, or elsewhere?

    Let me guess, you would suggest supernatural selection (God's intelligent design).

    No there are no excluded forms of non-random selection. You can make up any one you fancy.

    Consider the quantum nature of molecular bonds, there is a probability that a bond breaks and two atoms dissociate resulting in a mutation. Is this random event not in fact supernatural selection? God's intelligent design? Another example of non-random selection? What experiment could prove that God had not devised a very intelligent design, resulting in the dissociation of those atoms?

    The fact that you have had to question the meaning of "non-random" suggests to me that your thinking has led you to difficulty in distinguishing random from non-random.

    Darwinism looks at hereditary changes and seeks to distinguish the random from the non-random, those subject to experimental control, and those that are not. This is hard work. But even after much toil and study, for any mechanism of non-random selection that Darwinists can reproduce experimentally, anyone else can come along and suggest any other mechanism they want, including God's intelligent design.

    It is confusing and misleading because it is presented as an alternative to a neo-Darwinian explanation but is in fact NO DIFFERENT. I notice that about the one thing in my post on the question of information that you do not comment on is that frontloading "is NOT in any way an anti-Darwinian view."

    The rest of your post on this subject in deeply wrong about information theory. Your idea that all the possibilites exist at the start of the experiment confuses mathematical existence with actual physical existence. The configuration X had no physical existence until the end of the experiment. It came into physical existence then. The parallel in nature is much starker contrast: on the one hand we have the possibility of anti-biotic resist bacteria and on the other we have a physically real one that kills people. That was not present before and is now.

    I can think of no other purely scientific field where I would be chastised for not reading a mid-19th century textbook in full. I have in fact read excerpts from it, but why should I waste time reading in full a 19th century author who was not even a trained biologist, and in any case had a vastly inferior knowledge compared to today. Darwin knew nothing about inner cell functions and biochemical machines, genes and genetic functions, scanning electron microscopes and the structure of DNA, and every other piece of biological knowledge subsequently won by hard scientific progress.

    I get my knowledge of present-day Darwinism from reading Richard Dawkins, studying the web (especially the Talk.Origins web site, which is scientifically competent and strongly pro-Darwinist), and listening to competent Darwinist critiques of the ID fraternity, such as Glenn Oldham's above. I have also read the critiques of Darwinism made by other evolutionary schools of thought.

    So Darwin did use that phrase afer all , then? Perhaps you might care to tell me how he defined fitness in measurable scientific terms, and how he proposed to measure fitness independently of those who survive?

    I hadn't realised that Darwin himself fell into this tautological trap. The Endler syllogism above that I quoted was an explicit attempt to break out of a hopelessly circular tautology, but in so doing ended up in a very different place to Darwinism.

    Neil,
    I feel compelled to continue to challenge what I see as a continued confusion about this question of information and its implications. To add to the short reply I posted to you this morning I offer this by way of trying to get clear about what is meant and what is going on.

    Information Theory
    Let me explain my point about information another way.

    Harry has asked Fred to get something from Harry’s house. Fred asks ‘how do I get into your house?’

    Harry then makes statement A:

    A ‘To get in you must push the buttons on the combination lock on the door. There are ten buttons numbered 0 to 9 and you must enter five numbers in the right order. Start with 00000 then try 00001 and so on until it opens. Given the lock and this statement you have all the information you need to open the door.’

    And of course he is right that Fred does indeed have enough information to open the door. Like our algorithms he is going to try a trial an error approach, but he will get there sooner or later.

    But Harry also makes statement B:
    B ‘The first 5 numbers are 2, 9, 1, and 1 in that order.’

    Has Harry given Fred new information that he has not already given him?

    In information theory the amount of information associated with a statement or a state of affairs or an event is measures in terms of the amount by which it reduces uncertainty, that is by the amount it reduces the range of possible answers to a question, or possible states of a system.

    Statement A reduces Fred’s uncertainty by limiting the range of possibilities considerably. In fact the possibilities are reduced to 100,000 possible code entries for opening the door (00000 to 99999).

    But the addition of statement B reduces Fred’s uncertainty even more by reducing the possibilities from 100,000 down to 10 (29110 to 29119). Statement B clearly eliminates 99,990 possibilities or, better, reduces the uncertainty to one ten thousandth of what they were. The information content of statement B is therefore log to the base 2 of 10,000 (about 13.3 bits). The information content of statement A is thus 13.3 bits less than A plus B.

    NOW, suppose that Fred only had A and went to Harry’s house and after several weeks of punching button found that the code to get in was 29112. Would he have more information than he did at the beginning when he just had A? Of course he would because his uncertainty would have been reduced from the 100,000 possibilities down to 1 a drop by a factor of 100,000 (or about 16.6 bits). He would have more information than he had at the start.

    So it is with the chip experiment. The uncertainty is reduced. At the end we are no longer wholly uncertain as to what configurations will produce the desired function, we know that at least one will.

    Now Neil and Dembski will doubtless say that the analogy fails since the lock is not a computer program. But suppose it is. Suppose that it is a little black box programmed something like ‘if input = 29112 open door, else print ‘WRONG AGAIN!’ ‘ Well there you are, Dembski would say there is the number itself given to Fred as part of the information contained in the lock! He does have the information at the start so no new information is gained at the end after all.

    But this is incorrect. It is not true to say that 29112 is amongst the information that Fred is provided with in terms of information theory. This is because at the start of the process 29112 is NOT provided to Fred in a form that reduces his uncertainty. as a result IT DOES NOT COUNT AS INFORMATION TO HIM.

    It is quite clear that the system as a whole has the 29112 in it and it is quite clear that its presence will play a part in the correct result being reached. But it is not information in information theory terms that Fred has at the start.

    In natural selection the organism acquires information that it did not previously possess. The information is, of course, acquired form the system and is, therefore inherent (‘inherent’ is NOT meant as a weak word at all!) in the system in some way from the start. But Darwinian theory does not deny that the system is the source of the new information in the organism. If this is what Dembski means by front-loading it does not contradict the neo-Darwinian theory of natural selection.

This is because at the start of the process 29112 is NOT provided to Fred in a form that reduces his uncertainty. as a result IT DOES NOT COUNT AS INFORMATION TO HIM.

    It is quite clear that the system as a whole has the 29112 in it and it is quite clear that its presence will play a part in the correct result being reached. But it is not information in information theory terms that Fred has at the start.

    <snip>

    Glenn, I much appreciated your post – a thought experiment on “information” was just what was needed – I have certainly had to do a lot of head scratching in response.

    Information can be difficult and slippery concept to define accurately, so it is useful to spend some time on this. Dembski certainly agrees with you that “information typically measures the reduction in uncertainty that results from knowledge that an event has occurred”.

    I think that part of the response to your thought experiment must be that what counts as information for a human Fred is very different to what would count as information for a cybernetic android Fred (i.e. a computer). Human psychology intervenes at this point and adds its own unique touch. We have self-awareness and can make conscious choices, but computers can do neither.

    In both scenarios there are several important differences between the electronics experiment and your thought experiment. Harry knows that the specified functionality can be achieved (his door will open), and he also knows the right configuration parameters (the correct lock code). Furthermore, both Harry and Fred are human.

    Fred always gets to know that Harry’s door will open, and that the lock requires a five-digit code. This statement contains significant information in its own right, since it narrows the possibilities down considerably. The problem concerns Harry’s door, and not any other door. The relevant code is a 5-figure number, and not any other number.

    The problem thus becomes a deterministic search-and-find mission for a specific door with only one correct lock code. Thus Scenario A is very far from being information free, even for a human. For a computer the problem is completely specified at this point, and it will get to open the door.

    For a human, we must add the psychological dimension, since of course Fred doesn’t yet know the exact code. He rightly deduces that Harry is not expecting him to spend days pushing buttons. Instead, he deduces that Harry is being passive-aggressive and winding him up. Nevertheless the information Harry has passed over is true, and is theoretically adequate to open the door.

    Unhappily for Harry, Fred is an awkward so-and-so with something akin to obsessive-compulsive disorder [Frown] , and so he spends umpteen weeks camped outside Harry’s door trying up to 100,000 options in order to get it to open. Eventually he succeeds, since he has been given adequate information to open the door eventually by performing a search algorithm.

    In scenario B, Harry has written the code down for Fred, but one number has accidentally become illegible. Fred’s deterministic search and find mission is therefore much easier in this case. Fred rapidly tries all ten possible options for the missing digit, succeeding within a few minutes to open the door.

    The easiest case of all is when Harry properly gives Fred the full code. Fred just types the 5 correct numbers and he is in.

    We notice that in all cases the physical result is the same: Fred gets to open Harry’s door. The only difference is the timescale involved, and whether they are still friends at the end of it. In scenario A Fred’s doctor may also wish to see him. [Frown]

    METHODOLOGY OF ANALYSIS

    Given the psychological games that Harry is playing, we have to separate the probability of Fred ever trying to open the door, maybe after a long period of key tapping, from the probability associated with his having the correct lock code.

    I am going to look at the informational content of scenarios A and B using the equations on pages 3 and 4 of this paper by Dembski. These equations involve the informational content of correlated events. Having the correct lock code and trying to open the door are the correlated events, but of course Fred may still try to open the door without first having the full code.

    Thus we have prior event X – Fred ever trying to open the door - and we have subsequent event Y, Fred having the correct lock code given prior event X (Fred trying to open the door).

    Restructuring these probabilities in information terms as per Dembski (page 4), we get the information that Harry needs to pass over for Fred to open the door as: I(X&Y)=I(X) + I(Y/X).

    That is, the information associated with Fred [both opening the door X and also having the correct lock code Y] equals the sum of [the information associated with Fred trying to open the door X] and [the information associated with the correct lock code, given that Fred tries to open the door Y/X].

    SCENARIO A

    Since there are 100,000 possibilities associated with the lock code, the probability of Y is 10E-5. Therefore I(Y/X) would equal 16.6 bits if Harry had handed over the correct code, but since Fred does not yet have this information, I(Y/X) is zero for now.

    Now we know that the door will physically open with the correct code, but in scenario A Harry has no true intention that Fred should ever open the door. He is playing unpleasant games, and calling Fred’s bluff.

    Thus the probability of X (Fred trying to open the door) in scenario A is very low, but it is not zero. Fred does theoretically have enough information to do this, and may yet call Harry’s bluff. So the probability of X is certainly greater than 0, but of course it is far less than 1, a certainty.

    So what is the information associated with X? For the sake of argument let’s grab a completely arbitrary figure out of thin air and assume that in Scenario A the probability of Fred ever trying to open the door is 10E-5, i.e. I(X) = 16.6 bits. (We could make this figure less arbitrary by reference to data for various psychiatric conditions – not many healthy people would take up Harry’s bluff.)

    So at the start, the information passed over to Fred is I(X + Y) = I(X) + I(Y/X) = 16.6 + 0 = 16.6 bits – all in the form of the low but finite probability associated with the just-adequate information to do the job. Note however that it is a different 16.6 bits to the information he needs to open the door directly.

    Previously Fred had no possibility of a solution, but the just-adequate information has now brought one within his grasp. So when Fred gets down to work, Harry is horrified and thinks Fred is going mad [Frown] . Of course, if Fred is a not a mad human being, but a cybernetic android, he is as good as through Harry’s door already.

    After his long tapping session, Fred finally discovers the correct lock code. The door opening has now become a certainty, and at the same time Harry’s bluff has been well and truly called. Fred now has the correct 16.6 bits of information. The door opens and he is in.

    SCENARIO B

    In scenario B Harry was definite that he wanted Fred to open the door, so the prior probability P(X) of Fred trying to open the door is a certainty, and therefore I(X) is 0. Four correct digits have a probability of 10E-4, so the information content I(Y/X) is 13.3 bits.

    So Fred starts with 0 + 13.3 = 13.3 bits. Fred quickly finds by a blind search the 1 missing digit of value 3.3 bits. He now has the full 16.6 bits of information and he is in.

    CHECK ANALYSIS

    Suppose Harry clearly wants Fred to open the door and gives him the full lock code straightaway. Hence the probability of Fred trying to open the door is 1, so I(X)= 0. Fred has the correct 5 digit code of probability 10E-5, so I(Y/X) = 16.6 bits. Therefore I(X+Y) = 0 + 16.6 = 16.6 bits. Fred gets in quickly.

    CONCLUSION

    In scenario A, Harry provides the just-adequate information for Fred to eventually open the door. However, scenario A causes Fred a great deal of trouble, and destroys the friendship between Harry and Fred. Fred also ends up in a psychiatric hospital. [Frown]

    In scenario B Harry provides Fred with additional information that saves Fred a huge amount of time, and so he opens the door much more quickly. This preserves both the friendship and Fred’s sanity.

    Note that in both cases Fred manages to find the correct lock code and opens Harry’s door. The human consequences vary markedly, but for a computer there would be no difference.

    You may wish to comment on my informational analysis. I think it demonstrates that your thought experiment is more subtle and complex than you think, but I won’t be upset if you say it is fallacious [Smile] . I will return to the electronics experiment in due course.

    Well, Darwin's book isn't a textbook, it was a combination of a popularisation and a persuasion. And one reason to read it is that he's quite a good writer. It's fun.

    And he wasn't a "trained biologist" but that doesn't stop him being a brilliant one.

    And whats wrong with the business about "tautology"? That just goes to show its true.

    Moaning about "circular reasoning" here is just another bit of physics-envy, an attempt to constrain biology into the straitjacket of 20th-century "philosophy of science" based on the idea that mathematical physics is the only true science. Natural Philosophy vs. Natural History again.

    I am still chuckling over your description of Darwin’s Origin of Species as a “seminal classic of modern science”. Now if you’d said “an important classic of historical scientific literature that was unfavourably received by Darwin’s immediate scientific colleagues, but subsequently became the fountainhead of some profoundly influential thought, both within and without the world of science”, then we would have been in agreement.

    You have a strange concept of modern, but then it is a slippery and vague word at the best of times. Richard Dawkins is arguably far more deserving of the description “modern science”, and I certainly find him to be a very good writer. His descriptions of wildlife behaviour are a joy to read, but his “just-so” stories of evolutionary history should be filed under entertainment, not science.

    You also have a strange concept of prediction. The phenomenon of antibiotic resistance is long-established and well-understood. So I have no qualms in saying that the bacteria will reacquire the resistance that they lost due to the genetic engineering.

    The scientific explanation of the resistance involves a change to the shape of the site where the antibiotic would normally bind to the bacteria. Some bacteria in the wild are already shaped in a way that will not accept the antibiotic, thus giving them a natural form of protection. Hence they are antibiotic resistant already.

    Because some bacteria have always had the relevant genetic information, there is some evidence of penicillin-resistant bacteria in ancient Egypt, for example, possibly due to penicillin mould growth on wheat. The 1% who initially survive in your thought experiment are also evidence of this.

    The growth of antibiotic resistance is, as Endler put it, “simply a directional shift in the trait frequencies of a species”. There is no need for the creation of new genetic information, nor any requirement for fortuitous random mutations followed by natural selection.

    Sorry Neil, bacteria really do work the way LD said they do.

    You don't need the gene present, mutations can bring it along.

    I've got downloaded copies of nearly all the currently known bacterial genomes on my other computer right now & I'm writing programs to try to predict expression levels by codon usage... so bacterial genetics is near the front of my brain at the moment. Been reading a lot of papers about the things as well.

    I'm sure you have no qualms saying the bacteria will reacquire the resistance, because that allows you to say there is no need for the creation of new genetic information.

    However I never said the bacteria ever had resistance. If they never had resistance, logically they cannot reacquire it. Such a prediction would be wrong.

    It would also be wrong to predict that the 1% of bacteria that survived was evidence that "some bacteria have always had the relevant genetic information". The effect of the antibiotic follows a dose response. At sufficiently low concentration very few bacteria will be killed and the population would not be noticeably effected. At sufficiently high concentrations essentially all the bacteria are killed (remember they don't have resistance). At a somewhat lower concentration only 99% are killed. The bacteria do not have, nor ever had resistance.

    I also never specified how the changed base pair rendered the resistance protein ineffective. Therefore it would be wrong to predict it "involves a change in the shape of the site where the antibiotic would normally bind to the bacteria." It might not involve this at all.

    You have made three incorrect predictions.

    Let me help you to avoid further errors by being more explicit.
    The bacteria in question do not have antibiotic resistance. They have never had antibiotic resistance. They were grown from one bacterium which never had resistance. However, they do have a gene which is identical to an antibiotic resistance gene, except for one base pair. The base pair that the bacteria have causes a stop in the production of protein, resulting in a very short protein incapable of conferring antibiotic resistance. The bacteria are allowed to grow for many years in a medium which has a concentration which consistently kills only 99% of the bacteria.

    This would be a trivial experiment with today's technology.

    What would you predict might be the results?
     
    Posted by Ley Druid (# 3246) on :
     
    Sorry. That should read:
    The bacteria are allowed to grow for many years in a medium which has a concentration of antibiotic which consistently kills only 99% of the bacteria that do not have resistance (that is, don't produce an effective protein that prevents the killing action of the antibiotic). If the base pair in question were changed, the gene could produce a protein which would confer resistance to the antibiotic. That is, the same concentration of antibiotic would kill much less than 99% of bacteria with the gene that produces this protein.

    Any predictions?

    My predictions are only as good as the information you give me. In your first post the bacteria originally had antibiotic resistance until the relevant base pair was changed. Since this is an experiment after all, I had assumed that the base pair change was by genetic engineering.

    If you want to start claiming errors on my part, then you should have been a lot clearer in setting up your thought experiment - I see the goalposts moving wildly here.

    I'm currently reading this paper to get some more scientific background to your query. I''ll respond in due course.

    I never said the bacteria ever had antibiotic resistance. I said it had the gene, but with a base pair changed, so the protein was ineffective at conferring antibiotic resistance.

    It would be wrong to predict the bacteria would reacquire resistance because it would be wrong to suggest from the information that I provided that the bacteria necessarily previously had resistance.

    I anticipated you inability to see why this would be wrong. I didn't move the goalpost. I merely stated something explicitly, which was only a possibility before. Namely, that the bacteria never had resistance. In the present experiment, as in the first, it is wrong for you to suggest that the bacteria will reacquire resistance, previously because you didn't know they necessarily had it, now because you know they didn't.

    Indeed so. I think 'genius' is not an unwarranted term for Darwin. The more I read him, and the more I read about him, the more impressed I am with his abilities. To master such large areas of information, to imagine and conduct such relevant experiments, to make observations, to collect information, and to have such a good grasp of how theorising in biology works.

    Before I reply further to Ley Druid, here is some scientific background on antibiotic-resistant bacteria taken from this paper published in the scientific journal “Nature”.

    Antibiotics destroy bacteria by getting inside the cell and interfering with vital cell functions (especially protein manufacture). If the antibiotics are present in sufficient concentration this subsequently causes death to the bacteria.

    With regard to the phenomenon of antibiotic resistance, the paper makes the following statement:
    quote:
    Development of resistance is not a matter of if but only a matter of when. Given the large number of bacteria in an infection cycle, the rapid generation time, and the intrinsic rate of mutation of about 1 in 10E7, then a pool of 10E10 bacteria would have mutations on average in a thousand loci.
    Thus we might almost say that the development of antibiotic resistance is deterministic, that is, given certain conditions, it will certainly develop.

    The paper identifies three basic mechanisms for resistance, as follows:

    1. PUMP OUT THE ANTIBIOTIC.

    The concentration of the antibiotic inside the cell must reach a critical level to be effective and kill the bacterium. However, according to the paper, all bacteria have pumps that can remove unwanted materials from the cell interior. If these pumps are efficient enough, then the concentration of antibiotic never reaches a critical level. The antibiotic is simply removed faster than it can enter.

    As the paper puts it, with my emphasis:
    quote:
    As schematized in Fig. 3a, the drug is pumped out faster than it can diffuse in, so intrabacterial concentrations are kept low and ineffectual; bacterial protein synthesis proceeds at largely unimpeded rates. The pumps are variants of membrane pumps possessed by all bacteria to move lipophilic or amphipathic molecules in and out of the cells. Some are used by antibiotic producers to pump antibiotics out of the cells as fast as they are made and so constitute an immunity or protective mechanism for the bacteria to prevent being killed by their own chemical weapons.
    This certainly sounds like a mechanism where the genes are pre-existent. Of course not all bacteria are equal, and some have better pumps than others. Hence the development of the resistant strain with heavy-duty pumps.

    2. DESTROY THE ANTIBIOTIC WARHEAD

    Certain bacteria produce a deactivating enzyme which attacks the antibiotic in the space between the outer and inner membranes of the cell wall. In effect, the enzymes are border guards, destroying the antibiotic as it tries to enter.

    There are variations on this mechanism, depending on which bacteria and which enzyme are involved. The paper includes the following interesting comment:
    quote:
    The X-ray structure of an antibiotic phosphotransferase indicates an evolutionary relationship to a protein kinase, defining a route by which bacteria may have recruited an enzyme for the resistance brigade.
    Phosphotransferase is one of the enzymes now acting as a border guard, but evolved originally from the protein kinase. So again, it sounds like the raw material was available to be recruited and retrained.

    3.REPROGRAMME THE TARGET STRUCTURE

    This is the mechanism to which I alluded above, albeit somewhat inaccurately. The shape modification occurs to crucial biochemicals within the bacterial cell, rather than to the bacterium itself. As a result the target areas are reprogrammed or camouflaged, and now have a “low affinity for antibiotic recognition”.

    Note also the following comment:
    quote:
    This modification is carried out by a methyl transferase enzyme Erm that does not impair protein biosynthesis but does lower the affinity of all the members of the erythromycin class of drugs for the RNA, as well as for the pristinamycin class described below.
    So in this case the antibiotic resistance comes with a price of a reduced affinity for RNA. That may be a problem in some circumstances.

    Note also the comment:
    quote:
    The Erm mechanism is the main resistance route in drug-resistant clinical isolates of S. aureus and is present in erythromycin-producing organisms as a self-immunity mechanism.
    So this resistance mechanism already exists in the wild. Organisms that produce erythromycin have a natural immunity to this antibiotic.

    The three mechanisms outlined above are undoubtedly simplifications. There will always be more complex variations applicable to specific bacteria and specific antibiotics. But these three mechanisms will do me for now.

    So, before I get back to Ley Druid’s thought experiment, does anyone wish to comment on the basic science of antibiotic resistance? Have I missed anything?

    Dear Neil,
    Thanks for the paper, it is a nice review.

    Development of antibiotic resistance is not determinstic in the sense that "given certain conditions, it will certainly develop". The article explicitly says it is a matter of "when", that is, given enough time, the probability becomes very great. Just like flipping a coin, if you flip long enough you are "practically guaranteed" to see heads. However, if you only flip a few times, even with all the conditions required to see heads, you might only see tails. If the conditions are present immediately, why does it take time for many generations of bacteria to pass before the development of resistance to a new antibiotic? Why is it a matter of "when" as the article says?

    I wonder if you noticed that the article assumes the validity of "natural selection", also called "survival of the fittest"? As you are want to do, your selective quotation avoided a nice description of non-random selection
    quote:
    ...If one of those mutations confers resistance to an applied antibiotic, whereas all sensitive bacteria are killed, the resistant one will grow, fill the space vacated by its dead neighbours and become the domninant variant in the population.
    The article also talks about "selective pressures" and how bacteria are "selected". I am very curious as to what you think these ideas might mean.

    One fine point that has real world consequences - antibiotic resistance disappears again (through the same mechanisms) if the bacteria cease to encounter the antibiotic. All in accord with Darwin.

    Since you may possibly have missed it, here is the Endler syllogism that I quoted earlier on the thread. This is his understanding of what natural selection means:
    quote:

    If, within a species or population, the individuals:

    a) vary in some attribute or trait q (physiological, morphological, or behavioural) – the condition of variation;

    b) leave different numbers of offspring in consistent relationship to the presence or absence of trait q – the condition of selection differences;

    c) transmit the trait q faithfully between parents and offspring – the condition of heredity;

    d) then the frequency of trait q will differ predictably between the population of all parents and the population of all offspring.

    Now as far an antibiotic-resistant bacteria are concerned, we know that the earlier generation did not have the resistance (trait q). However, we can verify that, in the few resistant parents, mechanisms 1 or 2 or 3 are either already mobilised by the existing genetic endowment or freshly provided by a fortuitous point mutation. So we satisfy the condition of variation.

    We are able to count the relative number of offspring left by bacteria, both with and without the trait q. Those with trait q consistently leave more offspring, by a large margin. So we satisfy the condition of selection differences.

    We know that bacteria reproduce asexually and transmit these differences faithfully to their offspring. Trait q is duly transmitted to the offspring, so we satisfy the condition of heredity.

    And since we can demonstrate that most or all of the offspring subsequently possess trait q (the antibiotic resistance), then, according to Endler, it is at this point that we can say that this is due to natural selection.

    For another example of natural selection, consider red deer. In medieval Scotland they were forest animals, but with the destruction of so much native forest, the deer were forced instead to become creatures of open moorland and mountains. Since they now live in more demanding country, and no longer have the protection of large forests against the climate, the present generation have become physically bigger and more muscled than their medieval forebears. This too is an example of natural selection.

    So back to your thought experiment for a second attempt. I will assume that the bacteria have never had any resistance, but like all bacteria, they do have the basic cell pump (mechanism 1). They are also one base pair away from another mechanism, which could be 2 (enzyme border guards) or 3 (reshaped molecules), assuming that point mutations are needed for these.

    Placed in the hostile antibiotic environment, our first problem is to make sure that we don’t kill all the bacteria, but maintain 1% alive. If we were more liberal with the quantities of antibiotic, we might succeed in killing them all, bringing the experiment to a premature halt.

    Hence the control of the antibiotic quantity is an important factor in the experiment. This controlled dosage is mimicking the use of antibiotics in medicine where the dosage is inadequate. To my mind it is questionable whether such a controlled environment should be called “natural”, but that’s probably quibbling.

    Given that 1% of the bacteria do survive by some means, the acquisition of antibiotic resistance is then “not a matter of if, but when”. I predict the growth of resistance through a process of selective death.

    In the first stages we may generate an antibiotic resistant strain with the enhanced pump mechanism (1). This is not dissimilar to the selective breeding of farm and domestic animals for size or whatever. All our bacteria originally had pumps, and now they have been bred to have butch pumps. However, there is a limit to how effective the pump mechanism can become. We can still kill them all if we are not careful.

    In later stages, since our bacteria is one base pair away from some other helpful mechanism, we may get some fortuitous point mutations. This leads to the growth of a strain with resistance mechanisms 2 and/or 3 as backup to mechanism 1. At this point our bacteria have acquired very substantial resistance to the antibiotic.

    Any further control of the bacteria would require a different form of antibiotic. The Nature paper outlined some of the techniques being used in pharmaceutical engineering for bacteria that have become resistant to present-day antibiotics. All this is in the realm of demonstrable science, ably documented in the Nature article.

    Bacteria are a highly successful species, having remained as bacteria for 3.5 billion years or thereabouts. And bacterial resistance to antibiotics is an important scientific and medical questions. However, to suggest that the adaptive mechanism behind this phenomenon (natural selection) throws light on all evolutionary mechanisms is to claim far too much, I think.

    quote:
    Henry Troup said:
    One fine point that has real world consequences - antibiotic resistance disappears again (through the same mechanisms) if the bacteria cease to encounter the antibiotic. All in accord with Darwin.

    I am particularly intrigued by this comment. So, if you remove the hostile antibiotic environment, the bacteria lose the acquired resistance, and that is in accordance with Darwinian theory? How are the bacteria going to evolve complex adaptations if they cannot build on previous selective choices? Does this not undermine Darwinian theory completely?

    Henry Troup’s comment suggests to me that the adaptive mechanism responsible for antibiotic resistance is distinctly limited in the changes it can bring about. The bacteria can cycle about some form of mean, but can do no more than that. My understanding of the fruit fly evidence suggests the same.

    Darwin didn't do that. He suggested other evolutionary mechanisms.

    Not really, if you have a strong selective measure for a certain trait, that trait will predominate. If the selective pressure is removed then other traits may re-emerge.

    Imagine a homicidal religious dictatorship which thinks that all redheads are the result of sexual intercourse with demons and orders all redheads to be killed. Obviously there will be a strong selective pressure against redheads and the population will be blonde or brunette. If there is an insurrection against the dictatorship then the selective pressure will be removed and redheads will be found again as part of the population. Now if the dictatorship establishes itself for several thousand years then the gene for redheadedness will be eliminated from the population and if the insurrection takes place after this time it will be impossible for redheads to establish themselves as a part of the population, unless a mutation occurs which restores redheadedness.

    Something similar is, presumably, happening with anti-biotic bacteria. Given the existence of anti-biotics those bacteria who have resistance will be inordinately favoured. Remove the selective pressure of anti-biotics and other bacteria may compete just as effectively.

    Mutations are, generally, less helpful than not. In one of Richard Dawkins' books, for example, there is a photograph of a frog with its eyes inside its mouth. Clearly such a mutation has little chance of becoming established within the frog population. But a mutation may be neutral or beneficial. In an anti-biotic enviroment losing the resistance to anti-biotics will be fatal. If that pressure is taken away then losing such resistance will be of no great moment. A neutral mutation may establish itself within a population because natural selection does not allow for foresight. There is no gene which says, in effect: "Maintain anti-biotic resistance because the anti-biotics may come back" or for that matter "don't be redheaded because the dictatorship may be re-established".

    So if anti-biotics are removed from the environment the selective pressure for resistance goes away and non-resistant bacteria compete on otherwise equal terms. Which is what a Darwinian would expect.

    Actually, I think this is Faithful Sheepdog once again expressing his interest in tautologies.

    Bacteria remained bacteria.
    Bacteria remain bacteria.
    Bacteria will remain bacteria.

    It seems perfectly acceptable when he does it; he protests when he suggests that it's those evil Darwinists making tautologies.

    Callan, I enjoyed your illustration. I wish I could tell you an amusing story about a redhead. Sadly, the woman who broke my heart was a brunette. [Waterworks]

    Although this is probably not what you intended, it is possible to interpret your illustration to say that natural selection is far from being a creative force, and is actually a destructive force. It weeds out those who can’t cope in the new environment (the homicidal dictator) and destroys that particular genetic trait (the redheads).

    When the environment eventually changes again (i.e. the insurrection finally occurs), we have now lost the redhead gene, and have to wait for a lucky mutation to get our redheads back. In general there is no guarantee that this will happen at the time it is needed, especially if being redheaded suddenly becomes essential to survival.

    Of course, if you breed at the rate of bacteria, an occasional beneficial mutation is not an unreasonable expectation – the Nature article I quoted earlier gives an average of 100 mutations in a pool of 100 billion bacteria. It doesn’t say how many of these will be beneficial, but in rapid asexual reproduction only one is theoretically enough to restore our redheads.

    This whole scenario becomes very substantially less reasonable when we start talking about slow-breeding sexual creatures such as humans and other mammals. The time waiting for a beneficial mutation increases markedly, and with sexual reproduction there is in any case only a 50% chance that it will be propagated through the population.

    Your point that “mutations are, generally, less helpful than not” should be made into a banner and suspended over the bed of every Darwinist. [Smile]

    Run the numbers. In a sufficiently large population many, many mutations will turn up every generation.

    Sex maes it more likely that the beneficial mutation will prosper, not less.

    Yes, about half of them will disappear in the first generation - so what? Mutations are amazingly common. There are millions and millions around. Sexual reproduction allows different mutations to be combined in one individual - so evolution happens much faster. Recombination ius a machine for producing overwhelmingly more genetic layouts - do the sums - combinatorial explosion.

    I think you have a fair point here. My dubious logic went something like this: I was thinking particularly of slowly reproducing sexual species who have relatively few offspring, and I was assuming that only one partner had the beneficial mutation – the chances of both having it are minimal.

    What I should have said is that for every offspring born, there is only a 50% percent chance that this benefit will be passed on to the offspring. So for species that have only a few offspring, spreading this beneficial trait is less than certain, allowing for factors such as normal infant mortality and sheer bad luck.

    With a much larger number of offspring, then on average maybe 50% of them will have the beneficial mutation. In this case there may be numerous offspring possessing the beneficial trait, and the chances of the beneficial gene propagating through the population are now much better.

    Right at the back of my comments are the mathematical studies on population genetics done by JBS Haldane (which I would like to get my hands on) and the whole issue of how Darwinism explains the origin of sexual reproduction. With asexual reproduction the heredity of a beneficial mutation is not subject to such uncertainty.

    Most textbooks on Evolution (such as Mark Ridley's Evolution (Blackwell 1996 (2nd ed)) have the maths of evoutionary genetics in them and will cover the maths of the increase of beneficial mutations in populations.

    The subject of what advantage sexual reproduction has that offsets the considerable disadvantages to it is much discussed. Mark Ridley has a book on it called Mendel's Demon and he inclines to the view that, given certain other factors, sex allows bad versions of genes to be more easily got rid of, thus permitting genomes to be more complex in the face of the fact that the more complex the genome the more copying errors will occur. A helpful review of that book is given here http://homepage.ntlworld.com/anthony.campbell1/bookreviews/r/ridley-mark.html.

    I just posted a 3-page discussion on this, and now it has vanished into the Net!

    So I will assume that God doesn't want me to post it. Seeing as I don;t have time to repeat it now.

    Neil, what I was saying is exactly the mainstream description of population genetics.

    But I will summarise:


    Basically sex makes no difference to the survival chances of a rare variant or new mutation in a common species - that's obvious. If you think sex does make a difference then you need to get out a pencil and paper and write down what you think the chances are. Do the sums.

    NB except for highly deleterious or lethal mutations (which are obviously selected against) the main influence on the chances of survival of a mutation is variation in family size. The variance in number of offspring is the important figure.

    But once a mutation has spread through the population - just at random - sex makes it much more likely that advantageous alleles will increase because they can be joined together in one individual. In asexual populations this is terribly unlikely.

    Without sex they all have to compete with one another - my beneficial mutation A against your one B.

    With sex, individuals will turn up who have A and B (and C and D and E...)

    There is a complex pattern of variation, the "raw material" of selection, new genomes being thrown up with every generation. Every individual is unique.

    In fact (& no time to go into this now) one would expect evolution by natural selection to progress fastest in groups with rather low variance in family size, and that experience occasional large fluctuations in population.

    Two quick questions to check your understanding of population genetics (because you do seem to be missing something)

    - what do you think the random chance of a new neutral mutation eventually being fixed in a population is?

    - how many mutations do you think there are in the human species? (less variable than most common species)

    Sorry to hear that you lost 3 pages into cyberspace. That’s a bummer.

    Good questions, though. The maths of population genetics is definitely not something I presently have at my fingertips, but I’ll have a go nonetheless.

    On your first question, I already knew vaguely that the chances of a beneficial mutation fixing are related to s, the selection coefficient. This paper using Kimura’s ideas suggests that the chances of a new neutral mutation fixing are the same as q, its initial frequency within the population. In other words, the chances are tiny if only one member has the new mutation.

    As for your second question, I recently picked up some information from the ARN website, which suggests that the human genome mutation rate is 1.8E-8 per base pair for a genome of 3E+9 base pairs. Doing the arithmetic gives 54 mutations on average per genome – that’s 54 in each of us. I presume that the vast majority of these will be either neutral or deleterious, but a few may be beneficial.

    This webpage from the textbook that Glenn Oldham recommended suggests that there are at least three theories on the relationship between the rate of mutation and the selection coefficient.

    But this doesn't make me special, okay I know it sounds selfish, but its true, And do you seriousely believe the earth to be millions of years old, If we worship a God that can impregenate a woman, why can he not create a universe mid life, It's the age old question which came first the chicken or the egg. the egg needs to be heated by the chicken, The egg is created with in the chicken, before another chicken is created in the egg. It actually makes sense to me anyway that the chicken came first, as an adult chicken, with full knowledge on how to breed and produce more chickens. I mean God could have created the chicken sitting on its egg at the same time, but i digress.

    I had a friend come over and we were going through my interlinear bible (ie hebrew with lit english trans.) it was the mesoritic text and i don't know hebrew, but she is Jewish and so knows it. Istead of In the beginning God created the Heavens and the Earth, she read In the beginning God created heavens WITH the earth, yeh i know it may sound the same and I have always believed it, but it made it so much more understandable, for evolution surely the universe came before the earth, and yet the bible states that the heavens were made WITH the earth.

    and yet we digress from my original op, partially, if you have evolution, were we ever perfect and as such i suppose you are saying that we never received a sinful nature but it was a left over bit from our animal days, slight problem shouldn't we have improved, I have a feeling we are getting worse, or worse still we haven't changed, I am often surprised by things mentioned in the bible, and heres me thinking it only happened in the last 100 years, how wrong I am. We have not changed nor improved, our moral standing as a species, and this is why i believe that we have received a sinful nature when adam and eve ate the fruit.

I've never come across anyone claim they're held together by gravity. Also, I don't recognise the Job reference ... the closest I can think of is Job 38:31 "Can you loose the cords of Orion?"

    quote:
    All the prophecys are exact in timing, from Christ entering jerusalem, to Isreal becoming a country in 1945.
    Bollocks. I don't see anything, in any prophecies, that relate to the timing of events. Even if there are prophecies predicting the establishment of the modern state of Israel then they don't specify the time that would be (and, wasn't it 1948 anyway?). Though Christ rode into Jerusalem on a donkey, in fulfilment of prophecy, it can be argued he did it deliberately - and again, the prophecy doesn't mention a date.

    quote:
    In regards to mutations, if you can give me one concrete example of either animal or human mutating, that is both good, and can reproduce with each other or even with the previous type or animal I would like to know.
    What, you're genetically identical to me??? Of course not. No two humans or animals (except a small number of clones) are genetically identical, we all carry large numbers of small varients in genes - doesn't stop us reproducing though.

    quote:
    The world itself is so delecately balanced and intricate, you can change an entire eco system and destroy by taking out one species of animal. or introducing a new one. To think that God didn't make this at once exactly the way it was supposed to be, is not logical. Evolution is not logical.
    The world, as it is, can be very easily changed is without doubt. But, that's the thing, it changes as circumstances change (eg: by the introduction of an alien species to an environment) but it isn't destroyed. It may become less habitable for some species (including man), but it will adapt. We've seen it countless times before - the development of disease resistance is well documented, and is the response of an environment (eg: a species) to the introduction of a new pathogen. It is all an example of evolution in practice. It is entirely logical.

    quote:
    We as humans have not changed over at least the length of the bible, so guessing about 7000 years or so, If evolution existed we should have changed into something better then what we were which is the same as what we are.
    I disagree. Though it's impossible to actually quantify how much humanity has changed, there have been small evolutionary changes. There are diseases that are now less severe than once they were due to evolution (eg: sickle-cell mutations providing immunity to malaria, I don't know how recent that mutation is, but it's only present in a portion of the human species).

    Oh dear, oh dear.

    I know Alan's already disembowelled Anij's little collection of misinformation, but there's still bits that need putting out of their misery.

    quote:
    Count your bones, Men and women do have a different number of bones.
    That's as maybe. But they have the same number of ribs. Do you know how archaeologists identify whether skeletons are male or female? Hint - it's a lot harder than just counting the ribs.

    quote:
    As I said before I do take the bible litterally, there is too much info in it that is true that man did not know until the last 500 years or so
    If that were so (which it isn't as we shall see) why do you assume that the Bible being true means that it is literal? Methinks you have two concepts confused here.

    quote:
    that orions belt is held together by gravity. No other stars are infact held together in there constelations by gravity relating to each other. and yet in job, the oldest book written, it says so.
    As Alan said, they aren't. The Pleiades are, but so is every other star cluster. Nothing unique. I think you half-learnt this from a questionable creationist or literalist source. They told you wrong. I wonder what other lies they fed you? Have you also heard that the Earth's magnetic field is weakening and would have been impossibly strong millions of years ago? Did they also tell you that the sun is shrinking five feet every hour? Or that the year gets half a second longer every year? What about geologists not being able to explain why sea creatures' fossils are found on top of Mt Everest? Or there being not enough salt in the sea if the earth is millions of years old? None of the above are true, but they're lies generally spouted by the same organisations and sources that tell you men have fewer ribs than women and the speed of light is slowing down. Open your eyes. Creationist sources are shameless liars.

    quote:
    (I will have to look it up, its in one of Gods speeches to Job). All the prophecys are exact in timing, from Christ entering jerusalem, to Isreal becoming a country in 1945. How can I not take it litterally.
    Bollocks, as Alan said. There are no dates given. It's a matter of interpretation. And were it not, why does "correct" mean "literal"?

    quote:
    In regards to mutations, if you can give me one concrete example of either animal or human mutating, that is both good, and can reproduce with each other or even with the previous type or animal I would like to know.
    As Alan said, we all carry de novo mutations, but we can still interbreed with other humans. Sickle cell anaemia is a case in point - a significant number of black people especially carry the sickle cell mutation, but can still produce viable children with non carriers. There's your concrete example. You don't actually know much about biology save what your creationist liemongers have told you, do you?

    quote:
    It is very very very rare that a mutation occurs, (realistically) and its even rarer for that mutation to be good. A friend of mine's wife has a genetic mutation, nothing physical is apparant from it, she is fine, but there son died at 3 months because her mutation combined with his "normal" genes, meant their son came out with a hole in his heart and one of the veins in the wrong posistion, he fought, and so did the many talented doctors and nurses but it all didn't help.
    Some mutations are deleterious. The vast majority are neutral. A small proportion convey some advantage.

    quote:
    I don't know what would have happened if she had married some one with the same mutation. but clearly it doesn't help to stay with "normal".
    I think you're confused here. Usually these genetic abnormalities are expressed when two people carrying the abnormality produce a child who inherits the faulty gene from both parents. I do not know what condition you refer to, but I know of no genetic abnormality where the heterozygous condition is the dangerous one. Besides, in order to have a heterozygous child, the mother would also have to be heterozygous. Why was the condition harmless for her but fatal for her child?

    quote:
    Beside why would God waste so much time developing something that was going to change and the previous become extinct. It doesn't make sense.
    If that's the way God wants to do it, why not? Individuals die and their progeny live on; why is it so weird for God to introduce modification into this descent?

    quote:
    And when I say that God created the earth and the universe midlife. what I am saying, is that it is no point in him saying on the 3rd day?? let there be stars in the heavens, but the light won't reach earth for a few million years.
    Problem is we don't just see the starlight. We see events - events happening in stars millions of light years away. If the universe is young, these events never really happened. God has created a false history. Can you trust this God?

    quote:
    Well its amazing that man kind some how was able to navigate the seas for millenia before the stars shone. Adam can't have been created as single celled fetus, he wouldn't have survived, nor even as a baby, he wouldn't have survived. He would have to be at least early teenage hood so he could gather food for himself from the garden. When I say mid life I mean that everything is at least in adult form able to sexually reproduce.
    God creating an adult Adam is one thing. God creating an adult Adam with an old fracture that has partially rehealed, a scar on his arm and a faded tattoo on the other hand is creating a fraudulent history. And that is how the universe looks, not just old, but with a history.

    quote:
    Mutations generally can not.
    Yes they can. I used to breed guppies (well, the bloody things breed themselves if you don't put other fish in to eat the fry, but I digress). Ever so often a mutation would occur - deformed spine, or a different colour eye. These fish were freely able to breed; in the case of deformities is was necessary to forceably prevent the individual from breeding and passing on the deleterious mutation. Your claim is simply wrong.

    quote:
    Also in animal society mutations would be seen as a threat and they would be killed by other animals, (unless of course that mutation was a huge horn that could slice through stone. Even humans did this, when a child was born with two different coloured eyes they would be left to die.
    The vast majority of mutations have effects that are too small to be obvious. A huge horn would be the sort of saltational jump that is not thought to be involved in evolutionary change.

    quote:
    The world itself is so delecately balanced and intricate, you can change an entire eco system and destroy by taking out one species of animal. or introducing a new one.
    No, they change when that happens. Ecosystems evolve along with the organisms within them.

    quote:
    To think that God didn't make this at once exactly the way it was supposed to be, is not logical. Evolution is not logical.
    Stop working with your own logic only, and start including irritating side issues like "evidence".

    If you think God but the fossil record there on purpose as to add history, this I disagree with. I believe every one of those animals did exist, and for various reasons, the main one being the flood, they have become extint over time.
    The flood, for which there is absolutely zero evidence. Please don't tell me you're going to try to suggest that the fossiliferous strata were laid down by the flood - even the desert palaeosols....

    quote:
    We as humans with our grand ol knowledge of right and wrong have contributed to this ourselves, Is it so hard to believe that the humans of pre flood even post flood days did not contribute to the extinction of flora and fauna.
    I'm sure we've been doing it for tens of thousands of years.

    quote:
    We as humans have not changed over at least the length of the bible, so guessing about 7000 years or so, If evolution existed we should have changed into something better then what we were which is the same as what we are.
    This is a bit like watching a swimming pool with a pinhole in it for ten minutes, and declaring that because you can't see any change in the water level, it won't go down at all even given a couple of months. Do you have any conception of how tiny a period 7000 years is in evolutionary terms?

    But you're wrong anyway. Evolution is a change in relative gene frequencies over time, and I'll bet the incidence of genes that give rise to - for example - myopia - is higher now than 2,000 years ago, owing to the invention of spectacles.

    Quite simple, really. Adam means 'mankind'. The myth accounts for the imperfection in life, and points to perfection. As it was in the beginning, it shall be without end. Only, we now know about evolution, and that death did not come into the world because of a Fall.

    We are all part of the Old Humanity, we are all part of the Old Adam (Humanity). By the grace of God we can become like Jesus, who role modelled what the next level of humanity is and will be.

    The empowerment comes from Jesus through the Spirit. We experience a Now / Not Yet. We change as we follow Jesus (Now) but fail also as the Old Nature wins over the New Nature.

    The Old Nature is wired into our flesh, our biology, that is why we die physically. Without death and resurrection we couldn't be perfect as Jesus is. The Old Nature has a survival instinct, which can lead to what is called sin. Why is Martyrdom the ultimate glory? Because it completely opposes the survival instinct through faith.

    Just a few of my attempts to explain things taking evolution into account. A reframing of Christianity if you will.

    Because the science of the world is an entirely different issue to the nature of, and need for redemption. It makes me rather angry that people continually try to make one into the other.

    The world is wonderfully put together - however that was done. Most scientists would probably agree that mankind is having a negative impact on it. Hence the story of the fall is a profound truth on a global as well as an individual level.

    I would say that individuals, societies and the natural world need redeeming and that is something we cannot do on our own.

    Only if one believes God to be unknowable. Christianity has traditionally stated that God can be known, that God has attributes similar to that of humans. The reason why science has been so devastating to Christianity is that its discoveries seem not to have found the comprehensible divine patterns that Christian theology expected to find. By this I'm not referring to literal interpretations of Genesis but rather evidences of the workings of a mind which we can understand.

    So with Darwin: It's not evolution itself that causes problems for Christianity but that the reason for evolution is simply survival of the fittest. One can place God at the start of this process, but it pushes God beyond the bounds of what we can know.

    On the contrary, I think science has shown that processes that are seemingly incomprehensible are actually able to be understood (to some degree or another). There are patterns (and yes, I appreciate that they are complicated) and we can make general statements that explain the things we see. I accept that there is a lot we still do not know.

    Frankly I don't understand your point re the difference between our understanding of science and God. Surely advanced theology suggests that whilst God in theory is comprehensible/capable of being understood (otherwise there is absolutely no point in even attempting to understand) in practice our humanity means that we will never hope to get a complete handle on him. This is exactly the same as my understanding of science.

    Many Christians who are scientists find endlessly incrasing reason to worship God as they see more of the workings of the natural world.

    I Adam isn't an historical person, the whole meaning of these verses fall apart:
    «Therefore, even as through one man sin entered into the world, and death by sin, and so death passed on all men inasmuch as all sinned: for until the Law sin was in the world, but sin is not imputed when there is no law.
    But death reigned from Adam to Moses, even over those who had not sinned in the likeness of the transgression of Adam, who is the type of Him who was to come; but the free gift shall not be also like the offense. For if by the offense of the one many died, much more the grace of God, and the gift in grace; which is of the one Man, Jesus Christ, abounded to many. And the free gift shall not be as by one having sinned; (for indeed the judgment was of one to condemnation, but the free gift is of many offenses to justification. For if by one man's offense death reigned by one, much more they who receive abundance of grace and the gift of righteousness shall reign in life by One, Jesus Christ.)
    Therefore as by one offense sentence came on all men to condemnation, even so by the righteousness of One the free gift came to all men to justification of life.» (Rom 5:12-18)

    In the Fall thread in Purgatory I gave what I think is a useful way of thinking about the causality of sin and death. I think sin did (and does) cause it, but not in the way you mean.

    If you're asking how we know that death didn't come into the world because of a fall and you mean it in the cause-and-effect within the universe sense, then to disprove this, we have to identify the fall and then show that death existed before it.

    If the fall was historical then I'd have to place it in the time period in which humans have existed - we are still assuming the Fall is a result of human sin? Fossil evidence shows dead animals from an age orders of magnitude greater than the age of homo sapiens as a species. Either this evidence is falsified (by its creator?), or the entire scientific community is mistaken as to its age.

    This, if I'm not mistaken, is why ken and some others think Young Earth Creationism is actually a pretty nasty heresy - it accuses God of deliberately creating a fossil record which is basically a lie. (I know you've said you're not a YECcie but I think the basic argument here is useful)

    I don't see things that way. I regard it as a mistake that leads some sections of Christianity to reject science on the grounds that it is opposed to religious truth, and, far more seriously, leads many scientifically trained people, such as any who've had a decent modern education, to reject Christianity on the grounds that it is opposed to scientific truth. Which is rubbish.

    Do you want the truth, even though it may mean abandoning what you thought to be true?

    You see, if Adam and Eve didn't exist, then I couldn't give a damn about what Paul wrote about them. He was simply using the story he was brought up with for his arguments. We would need to reframe what he wrote, now we know he was using myth, without realising it was myth perhaps.

    If Adam and Eve didn't exist, then anyone who insists they did, because the Bible says so, is defending an untruth. Get my point?

    Others have commented about sin and death and have covered what I would say.

The question is, did He do so? And, in answer to that question I see absolutely nothing in Scripture that compels me to accept that conclusion, and everything in me says I wouldn't like the sort of God who creates something that to all rational enquiry appears to be billions of years old when it isn't.

    Unlikely, maybe, but not impossible. The mechanisms inherent in the universe are very powerful when it comes to sorting things out. Natural selection is a very powerful mechanism for sorting out variations that are better suited to the local environment.

    Two reasons for me.

    One, there is no evidence to contradict the resurrection (except the "dead men don't rise" which is a very weak argument - it's a miracle, d'uh). Whereas there is evidence all over the place that the earth is much older than 10000 years.

    Second, the death and resurrection of Christ is an integral, vital part, of the Christian faith. If I couldn't accept that I wouldn't be a Christian and would probably not be here to debate with you. The mechanism God chose to create the heavens with the earth are not important.

    Surely the main point is that if the world really is only 6,000 years old then God has a lot of explaining to do about why he made it to look several billion.

    Sure, I believe God can do miracles. But there is a difference between miracles and deliberate deception IMO.

    How old? Honestly I don't know. Who does? Big bang is just a theory. Just recently they made a discovery about galaxies being formed two billion years earlier.

    When Newtonian physics was very successful in solving and predicting a lot of phenomena, scientists attempted to apply it to quantum and near light speed phenomena only to find it wanting. Isn't it fair to say that scientists might be making a wrong prescription to solve problems involving conditions near birth of the universe and cosmic expanse with our ill equipt present theories.

    Physics has this doctrine that theories for them to be theories must be falsifiable, this means that they are only applicable to a certain limit. Like Newtonian mechanics being proved false when applied to quantum mechanics. So far Eintein general and special relativity hasn't been falsified yet. So shall we swallow hook and sinker that his theory is applicable to all cosmic phenomena? This would be pushing it too far.

    <snip>

    As to the Flood, there are evidences also pointing to its occurence, marine life fossils on high grouds and big volume of fossils of animals alienated from its habitat. I'm no specialist on this issue, but from what i read, there's a fair weight of evidence to Noah's Flood. As to the goeologic column, there is no column that is complete . Some columns have layers that are missing in others.

    Now there seems to be a lot in here to respond to. Forgive me as I don't think I can do all of it (I copied all the sections of the post relevant to this thread if anyone else wants a go).

    First, with reference to physical theories. I think you've misunderstood what is meant by "falsifiability" in relation to science. It doesn't mean that scientists expect theories to be false and just waiting to prove it. It means that the way to test just how good a theory is is to produce predictions that are open to experimental investigation - and that the design of those experiments should be such that if the theory is wrong then the experiment fails. So, as an example, when Einstein proposed his General Theory of Relativity this competed with the existing Newtonian theory. An experiment was needed to decide between them. Now, both theories made predictions about objects attracting each other - you can make as many measurements of apples falling out of trees as you like and you couldn't prove either theory wrong (and hence, the other more likely to be right). You could, however measure light from distant stars passing close to a massive object, such as our sun, and determine if it's path is bent - if it is bent then Newton was wrong. This was done during solar eclipses.

    Second, re: the Flood. The existance of marine sediments on mountain tops is very adequately explained by plate tectonics and resulting geological processes over extended periods of time. No need for a Flood to explain them.

    Hmm. Well the problem, Sanc, is that these are very sweeping statements. First, there are no complete geological columns, quite true. But geology is a hard subject and the answers are not obvious. Columns are produced from taking the wide view of very large areas. Now, there happen to be some places in the world where it is possible to piece together which rocks are oldest (ie lie near the bottom) and which are youngest (ie nearer the top). One of these places happens to be the UK where we have rock from all of the geological periods. Of course, in no one place do you find all of them, but given that things like erosion will be going on all the time, this is hardly surprising. Now, you can say that missing rock is evidence of a failure in the theory, or you can say it is evidence that the whole story is more complicated than it first appears. Personally, having skeptically and critically studied the evidence in the field, I can say that although there may be areas in geology that a ruthless person could pick holes in, this isn't one of them. And frankly, only someone who has studied little or no geology would even suggest such a thing.

    I'm afraid that if there was a global flood event, we would expect quite different rock formations than the ones we have. Sea animals on the top of mountains, unfortunately, is not evidence. I have already aluded to the fact that it would require completely different conditions that we observe today to have the amount of limestone laid down.

    The unfortunate thing is that people latch onto other people who appear to be supporting their own theological position without ever critically examining the evidence or the person making such assertions.

    What is not appreciated is that 1) geological theory was formulated largely from empircal evidence measured in the field, against the common understanding of the time (and therefore needed very strong evidence indeed) and 2) had nothing whatsoever to do with the development of evolutionary theory. To reject the theory without studying the evidence is to spit in the eye of the men who followed where their instincts led them and wrote down what they saw.

    And the "geological column not found complete in situ anywhere" thing is one of the lies professional creationists tell their credulous followers, alas.

    This is not unusual. The likes of ICR and AiG who say this stuff wouldn't know truth if it wore a badge marked "I am truth", and bit them on the arse whilst saying "I am truth, I am truth", and have pretty much the same relationship with integrity.

    Actually, although the geological column is no-where complete, there are plenty of places with a good few tens of millions of years in once heap, and a few with hundreds.

    Also, with the exception of a pretty big gap (in the Triassic IIRC) and a couple of smaller ones in the Tertiary, almost the whole of the column since the Cambrian is found in Britain. Which is just one of the reasons why the great age of the earth was first worked out by British scientists (almost all of whom were Christiansm, for what its worth)

    Superb Karl.

    In 'another place' I declared that the universe being 12-15 billion years old, like the cooled surface of the Earth being 4.5 billion years old and life about 4.2 now I think, is God given fact.

    Sanc, who is much nicer than I ever will be, disagrees.

    I take on board all of the provisos as to what a fact is: Dawking declares evolution to be one and I'd have to agree.

    If God is Creator, and I believe He is, then whatever processes over time are revealed by science, are facts. God given facts.

    However, he said that if someone could show how the eye developed from earlier precursors, this difficulty would not be an issue.

    while it is easy to see how a primitive eye could become more complex, the question of how it all started in the first palce has puzzled many scientists. The researchers in the article above have come up with a good explanation.

    How will this affect Creationism/Intelligent design? Will the old "the eye couldn't have evolved" argument finally be laid to rest?

    Callan, this comment is a clear ad hominem and frankly borderline hellish. It is out of place on this thread.

    The fact that you do not distinguish between "creationism" (usually understood as young earth, flood geology, 7-day Genesis literalism), and the much more scientifically and philosophically nuanced approach(es) adopted in the Intelligent Design fraternity, suggests to me that you are unaware of the important scientific and philosophical issues involved.

    Karl's comment on the evolution of the eye involves more wishful thinking than hard scientific reality. If you think the problem of the evolution of the eye has been solved scientifically, then I have a bridge to sell you. [Smile]

    ID is only marginally closer to good science than YEC is.

    Callan is spot on. Both YEC and ID are driven by the same need to find something of which one can say "Ha! God must have done that!"

    Required in no other area of science, and no more than a regurgitated God of the Gaps argument.

    What Alan and Karl said.

    ID is, of course, much more scientifically and intellectually nuanced than YEC. It is still an ideological rather than a scientific issue. ID Methodology consists at attempting to poke holes in Darwinism and triumphantly exclaiming: "Explain that!" It is distinguished from YEC by the sophistication of its rhetoric. Its methodology is painfully similar.

    Is that the issue? I'm sure that most scientists would agree that one can, however, the philosophical teleology that might be accepted by an individual on a philosophical level are not part of science. It strikes me that in fact this is striking at philosophical rather than methodological naturalism.

    Given the successful way in which evolution does explain so much, I would suggest that the areas in which its explanatory powers are less strong (examples would be welcome) are grounds for considering how the theory can best be modified, rather than completely rejected.

    I certainly fail to see ID as a better theory. I can think off the top of my head of a few things that ID fails dismally to explain - starting with the wiring of the vertebrate retina and moving onwards.

    So, what is science then if not methodological naturalism? I agree you can be fully scientific and acknowledge the inadequacy of methodological naturalism in addressing, say, the beauty of a work of art. But, how can you be fully scientific if you consider methodological naturalism to be inadequate to address questions of the nature of the material universe.

    I don't think anyone is saying Darwinism should be exempt from what you correctly identify as good science. Where ID differs from good science is the motivation for such criticism. Rather than trying to get to a better understanding of the phyisical universe ID seeks to find evidence that the phyisical universe is beyond understanding. ID seeks to find gaps in understanding, not to try and fill them by better science but to fill them with "God did this" and thus put them beyond the bounds of science to explain. Naturally, scientists don't react well to claims that they can't investigate something interesting.

    Well, thats rather the point. The moment it does that, it ain't science. If science got more data and better results by rejecting methodological naturalism and importing a philosophical teleology, I'm sure it would adopt same. Those who objected on philosophical grounds would be left behind like those indignant Victorian clergymen, who insisted that evolution was incompatible with Genesis. But as ateleological methodological naturalism is the only game in town, at present, it seems rather unlikely that this will happen. Without methodological naturalism there can be no scientific method, at least as it is understood at present. What you want is science to effectively censor itself in accordance with your theological beliefs.

    Of course, Darwinism is falsifiable, that is why it is a scientific theory. ID isn't because it is predicated on the existence of a deity. Metaphysics, not science.

    I am only a poor humanities graduate, who knows little of such matters. But my understanding is that, yes, your first sentence adequately sums up the view of most serious evolutionary biologists as to the adequacy of ID. I'd have thought that was pretty damning, myself. Clearly they haven't thought of the social and political implications of their opinions.

    I think I have to disagree here.

    YEC is simply unbelieveable if you think there is a real objective world out there. It is flying in the face of all observation. Down there with a flat earth and the moon being made of green cheese. I frankly, think everyone who thinks they believe it doesn't really understand the issues.

    The only let-out is the Omphalos - the world as a sort of great big virtual reality, a fake creation (in which case of course all scientists would have to carry on assuming the world was old because God would have done the faking so well that worjing with a young earth would lead to wrong results!)

    An Old-Earth creationism, whether pinned on "Intelligent Design" or not, can be made compatible with observation. I'm not saying the various versions are true, but it is at least possible to believe them.

    Though, in the end, I suspect they go the way of all "God of the Gaps" theories. There are (probably) no gaps in creation. God's design and natural processes are indistinguishable. (At least to us on the "inside")

    So the really funny thing is that whichever approach you take the scientist thinking about the origins and history of life has to go about things the same way - ID, or even YEC+Omphalos make no practical difference!

    Bending over backwards to be fair, the most common forms of ID seem to assume divine intervention in the origin of life, and maybe in the very first bactreria-like creatures, but evolution by natural processes since then. With perhaps a push to the human species.

    Now as we don't actually know much about the origins of life, and there are persuasive arguments (most recently from Carl Woese who knows what he's talking about) that normal evolutionary methods can't tell us much about it, there is a big gap for ID to make assertions about.

    But thats all they can be, assertions. It might genuinely be impossible to know, short of a time machine. Or divine revelation.

    Callan, the last sentence is absolute bollocks - I have no desire to censor anything in the realm of truth and knowledge– so I suggest you withdraw the inference. Before I became too ill to work, my whole professional existence depended on a solid foundation of scientific and technological knowledge applied intelligently. In the nuclear world I have seen plenty of things censored, but it wasn’t because of someone’s theological beliefs!

    The idea that we must accept, as a basic starting position, an ateleological methodological naturalism is not something determined scientifically. Such a starting position is clearly an a priori philosophical decision, and not scientific at all. Nevertheless, I will be the first to concede that science has achieved many great results using such a methodology.

    However, that doesn’t mean such a methodology will deliver true results on every occasion. There are many cases where it will give results that are not even partially correct. As a simple example, I refer to the role of accident investigations where the role of human psychology interacting with technology is often essential in understanding “what went wrong”. In this case you simply can’t leave intelligent purpose out of the equation and expect to be correct.

    Incidentally, my reference to “social and political ramifications” was a poorly worded reference to how Darwinian ideas have been adopted in academic fields far removed from biology. As I wrote, I particularly had the so-called science of “evolutionary psychology” in my sights.

    Alan, with respect, I think you are being a little naïve. Hard-line Darwinists such as Dawkins (and many others) have not hesitated to draw all sorts of philosophical and theological conclusions from their supposedly value-free scientific work. They disingenuously use the prestige of a supposedly naturalistic science as the basis for the acceptance of their distinctive personal views.

    Would anyone have given a moment’s notice to Panspermia (the theory that primitive life on earth was seeded from outer space) if its proposer (Francis Crick) had not coincidentally been the discoverer of the structure of DNA? Would anyone listen to Dawkins’ personal world views about “selfish genes” and the desirability of atheism if he were not an Oxford professor for the “public understanding of science”?

    There is no control on this behaviour from the scientific world, even though such behaviour falsely claims the scientific high ground before a public that is generally scientifically illiterate. In such an unbalanced scenario, it is only to be expected that a robust response is likely to come from other able members of the scientific world who can see the games being played.

    This is the context in which the ID fraternity has been making its case. They are convinced that it is quite possible to do science with integrity from an explicitly theistic perspective, as were many of the early famous scientists (such as Sir Isaac Newton, who was a young earth creationist to boot). Part of the battle is for scientists to be more self-aware and open about their own philosophical positions.

    I think the criticism that ID simply resorts to “God of the gaps” thinking is simplistic. It doesn’t reflect the reality of much ID material that I have read on the Internet. I think it is caricaturing it to suggest that “God did this” represents the end of the investigation for the ID world. Rather, the question is whether an understanding of intelligence and purpose abroad in the universe, in combination with conventional scientific tools, helps us to arrive at a true knowledge.

    As far as I can see the ID world is actually a very broad church, and there are many different viewpoints within it. Compared to hard-line Darwinism, it comes across to me as refreshingly open and liberal in its culture. Even some theistic forms of Darwinism are probably compatible with ID ideas.

It seems to be held with a psychological tenaciousness that would make the most convinced YEC blush. See the devoted Internet disciples of Richard Dawkins for the most obvious example of this.

    In general terms it’s a subset of liberal fundamentalism, of which there have been plenty of examples on the Ship.

    "Political conservatism" is the phrase you are looking for.

    What you are describing is what we used to call "social Darwinism" then "Sociobiology" then "Evolutionary psychology".

    And far from being held rigidly it is discussed and criticised and held up for inspection as much as - probably more than - any other branch of science.

    Yes. So? I never mentioned Dawkins [i]et al[i/], quite deliberately as I consider that when they step beyond the scientific fields in which they are undoubtably good scientists they cease to be good scientists and become very poor philosophers. In discussing what science is and how it works focussing on a small minority of scientists who have gained some notoriety in publishing their philosphical opinions widely isn't very constructive.

    Callan, the last sentence is absolute bollocks - I have no desire to censor anything in the realm of truth and knowledge– so I suggest you withdraw the inference. Before I became too ill to work, my whole professional existence depended on a solid foundation of scientific and technological knowledge applied intelligently. In the nuclear world I have seen plenty of things censored, but it wasn’t because of someone’s theological beliefs!

    The idea that we must accept, as a basic starting position, an ateleological methodological naturalism is not something determined scientifically. Such a starting position is clearly an a priori philosophical decision, and not scientific at all. Nevertheless, I will be the first to concede that science has achieved many great results using such a methodology.

    However, that doesn’t mean such a methodology will deliver true results on every occasion. There are many cases where it will give results that are not even partially correct. As a simple example, I refer to the role of accident investigations where the role of human psychology interacting with technology is often essential in understanding “what went wrong”. In this case you simply can’t leave intelligent purpose out of the equation and expect to be correct.

    With hindsight, the word 'censor' was unhelpful and I withdraw it.

    If methodological naturalism doesn't work, however, I would expect to see it breaking down in a realm of scientific fields. This appears not to be the case. Within your own field, I would imagine, methodological naturalism is the sole acceptable method of inquiry. If a nuclear reactor goes wrong, I doubt whether anyone would be terribly amused if someone postulated evil spirits as an explanation. (Alvin Plantinga, who I understand is a supporter of ID, has argued that all natural evil derives from the freewill of supernatural evil entities. I find this suggestive, not to mention amusing). I submit to your greater knowledge of the literature but I am unaware, to multiply examples, of any ID theorist criticising big bang theory, which is odd given that this is precisely the sort of area where the hand of the deity might be expected to be discerned. It seems a little counter-intuitive to argue that Planck time could be expected to run itself, but that the evolution of the eye required God to pop by and make a few discreet adjustments - quite apart from anything else it seems bad theology. God continually working within his creation is one thing, God being obliged to nip back at strategic intervals in order to fix bits is quite another.

    To be honest, I am not sure that accident investigations are a precise analogy. Human intervention is empirically testable and therefore falsifiable in a way in which divine intervention is not. If I hit a snooker ball at a certain speed and angle a geometer, with access to all the data, will be able to tell you whether the ball will enter a pocket. What he can't tell you is whether someone will walk into the room and pick the ball up, just before it rebounds of a cushion. But a mischeivous teenager is otherwise subject to the laws of science. The geometer, when told that there was a teenager in the room and that the ball did not enter a pocket on the rebound does not need to postulate an entity outside the scientific frame of reference to explain what happened.

    Surely the point is this: It is possible to criticise certain scientific principles. Even with all the evidence in front of you, it is possible to say 'no, sorry that just doesn't add up'.

    But to then say 'well, in that case we are forced to accept this other position x' seems a ludicrous extension of the Sherlock Holmes 'lie' that all truth is capable of being reasoned and therefore all explanations are available to be considered and accepted/rejected. I would be very surprised if we do not later find that many things we observe are actually fully explained by ideas we haven't yet thought of.

    It isn't an either/or. To reject the one is not to accept the other. And science can deal with uncertainty, whereas I'm afraid any entrenched position cannot.

    A human hitting a snooker ball in order to win a game is not a very good analogy of God's ongoing intervention in creation. ("Providence" as we used to call it)

    A better analogy would be a human writing a novel in which another human hits a snooker ball in order to win a game.

    Within the frame of reference of the novel there is - if the novel is well written - no way of telling the intervention of the author from the "natural processes" within the story - because they are all the same thing. All of the story is written by the author. If the author chose, and if they are a good writer, all of the story may seem to arise from its premises.

    In a similar way there is no way that we can tell God's intervention from natural processes becauses they are all God's creation. The only way we could possibly know would be from direct revelation.

    Looking around the universe for little anomalies that are evidence of the existence of God just doesn't work. It can't work - unless God makes it work. You can't do an experiment on God.

    It makes a good novel though - its partly what Moby Dick is about and more explicitly Dan Simmons's Hyperion books - which are to some extent spin-offs from Moby Dick.

    Such a pity he's wrong on so many issues. He claims that he's rebutting the view that where science contradicts scripture, it is scripture that should be discarded. The real state of affairs is that where the real world conflicts with either current scientific theory or current theological theory, it is the real world that is right and both scientists and theologians need the humility to be able to reform their views in this light. Scientists have it. Creationists usually don't.

    I wish I had a bit of time to read the article (sorry, I'll try and get to it at some point), but he is right ... evolution is the only game in town. At least, at the moment, scientists will continue to probe the theory, collect more data etc and it's always possible that sooner or later the evidence will start to push the theory beyond any option but to ditch it in search of something that better explains the data. Unfortunately for those who hold to the various Divine Intervention Creationist positions (ie: those who hold that God acted to create by intervening in the natural order in a way inherently inexplicable to science; including YEC, ID etc) there have been no such problems since Darwin first proposed his theory (to the contrary, all such investigation has strengthened the theory), and there's no guarantee that even if the theory is eventually discarded in favour of a better theory that that better theory would be any more favourable to Divine Intervention in Creation.

    Very interesting Geo.

    I was wondering when this would happen, having read the letter to Philosophy Now which obliquely hinted at it, and look forward to reading a more substantive treatment of Flew's change of mind.

    Flew's article on Falsification is perhaps the strongest case in favour of atheism I have ever read and should, IMV, be made compulsory reading at all theological colleges and seminaries.

    I have always darkly suspected that a certain type of militant atheist was really a closet believer who was angry with God. I'm not sure if this represents vindication of this theory or not.

    There's more detail here and some first hand quotes from him. He still seems to be very much in touch with the Secular Web people.

    He was asked what he would mean if he ever asserted that "probably God exists," and replied

    quote:

    "I do not think I will ever make that assertion, precisely because any assertion which I am prepared to make about God would not be about a God in that sense ... I think we need here a fundamental distinction between the God of Aristotle or Spinoza and the Gods of the Christian and the Islamic Revelations."

    Rather, he would only have in mind "the non-interfering God of the people called Deists--such as Thomas Jefferson and Benjamin Franklin."

    Flew also says
    quote:
    My one and only piece of relevant evidence [for an Aristotelian God] is the apparent impossibility of providing a naturalistic theory of the origin from DNA of the first reproducing species ... [In fact] the only reason which I have for beginning to think of believing in a First Cause god is the impossibility of providing a naturalistic account of the origin of the first reproducing organisms.
    but he says he is basing this on Gerald Schroeder's book The Hidden Face of God: How Science Reveals the Ultimate Truth (2001) and that
    quote:
    he has not yet had time to examine any of the critiques of Schroeder. Nor has he examined any of the literature of the past five or ten years on the science of life's origin
    It seems to be good old fashioned 18th century style Deism - plus Darwinism after the first cause has kicked things off with the single-celled organisms - and I don't think that's what most of those arguing for intelligent design have in mind. To quote Flew from another article

    quote:
    ``I'm thinking of a God very different from the God of the Christian and far and away from the God of Islam, because both are depicted as omnipotent Oriental despots, cosmic Saddam Husseins,'' he said. ``It could be a person in the sense of a being that has intelligence and a purpose, I suppose.''
    I don't think that'll make him too popular with the sort of people who want evolution thrown out of school textbooks!

    You are wonderful! Irenean theology emphasises that we and the world are in a state of becoming.

    «The trinity has profound existential meaning. The triune nature of God points to an interior spiritual life in him and and this life is the whole world. The revelation of the triune God is the antithesis of the conception of god as pure act. An abstract being which does not display within itself any concrete existence. There is in the holy trinity the One and there is his Other, and there is and egress, an issue a solution in the third... A static conception of God cannot be maintained. The Christian God can only be understood dynamically. In God there is a creative dynamic process which is accomplished in eternity.»

    Clearly if the world is seen as being in a "state of becoming" then one is forced into a position where God resting after completing Creation has got to be metaphorical - He hasn't completed creation yet. And, if the 7th day is thus metaphorical, logically so too must the previous 6.

    I can't see how someone following the teaching of Ireneus (if the above quote does correctly summarise Irenaen theology on this point) would have any difficulty with evolution. Indeed, Irenaen theology would almost drive you to accept evolution.

    Of course, it doesn't follow that someone accepting evolution as an accurate description of the method God employed in creation is Irenaen.

    Gerhard von Rad in his Genesis commentary speculates that the Sabbath day of rest actually constitutes God's future intention. It was the ongoing process toward God's Sabbath of shalom that created so much agony. The struggle of God was not so much with the original creation itself, but with human response to it. From the beginning the creation narratives were in themselves not pointing to a past completed action by God, but where rather oriented towards the future. This future was indeed God's rest, but was creation's rest as well.

    I've said before (probably on this thread) that I've always found the idea that the "7th day" of rest is sometime in the future attractive. That doesn't make the whole narrative refer to future events. I think it's more that the first "6 days" are symbolic of the current status; God is creating the heavens and the earth, he is in the process of creating humanity in his image, this process won't be complete until the second coming.

    I'm sorry to turn up, say my bit and ruin the flow of the thread, but I will anyway [Smile]

    I notice a lot of people saying YEC isn't scientific, and ID isn't much more, and this being a problem. As someone who comes from a scientific background (well, engineering really - useful science) I personally wouldn't hold science quite this high up. There was a wonderful documentry recently when Stephen Hawkins publically recanted one of his books, saying he now reckoned it wasn't correct or something or other. The documentry interviewed many scientists, many of whom were very confused. Some decided they disagreed with Hawkins recent conclusions because the information in the book seemed to work and they had spent years treating these as truths.

    Now this is very far from this debate I realise, but my point is this - why do we trust our scientists so much? It seems ever since we stopped being frightened of what they were doing we started treating them as our high priests. We now look to them to explain natural disasters and occurences. We look to them to explain why people are how they are, and why they do what they do.

    I see nothing wrong with the study of science, I am just questioning the trust which we give to scientists themselves, who ultimately define what modern day science is, and who are ultimately human and capable of error. I certainly know in the engineering world that all too often the pursuit of the best way of doing something is often prioritised lower than cost and effort.

    Having said that I am equally sceptical of the desperate stuff I see in creationist journals, full of scientists desperately trying to find factual encouragement for those who pin their entire faith on the earth being less than a few thousand years old.

    Personally I don't think I'll mind which was true at the end of the day. My faith is centered on Jesus, and any creationist or darwinist who does the same is ok in my book (not a very impressive book to be in)

    I'm sorry -- you have to be more specific -- recanting is not usually a word associated with a scientist deciding that an aspect of one of his hypotheses or theories didn't hold up. Using language like "recanted" to imply that therefore we can't trust any scientific conclusion is logically fallacious. It is in the proper nature of scientific enquiry to set forth falsifiable premises, test them, and build on the findings if they are taking you in the right direction, or reject them if it becomes clear they are unsupported. That is because science is answering different questions in a different way than theology.
     
    Posted by Alan Cresswell (# 31) on :
     
    It is hardly unheard of for a scientist to admit they were wrong. Albert Einstein famously described his cosmological term in General Relativity (to give a static universe, in accordance with then current understanding) as the greatest blunder of his career. Admitting to mistakes is a much greater mark of a genuine seeking after truth, in any area of enquiry, than any amount of fudging to fit all data to some preconceived notion of the right answer.

    That would of course be physicist, best-selling author, and occasional TV guest star Stephen Hawking, holder of the Lucasian chair in mathematics. As an engineer myself, I believe that exactness counts.

    Hawking has invented and reinvented theories of black holes and quantum gravity in a most laudable way. It never seems to bother him to say "I used to think X, but because of Y, I now think Z." A man to admire, intellectually, at least.

    Yes I agree, I am glad Hawkins stood up for what he thought was true, I think I would have just let everyone go on believing what I thought was wrong. And my point isn't that we can't trust any scientific conclusions Laura, and I only used recant because I can't think of a better word! My point was that we should keep in mind that some of the things we take for granted will be revealed to be nonsense in 50 years time, and that is just a fact secure in the history of science. Much will continue getting closer to the truth and more and more exact, but it is still good to keep that in mind. Bear in mind Laura I am just questioning our trust in them, not demeaning it.

    Ken when I said back when people were frightened of scientists I meant more centuries ago, when they used to torture people for saying the world was round etc.

    I do still think people trust science and scientific conclusions these days however, but I see your point. Certainly on this thread there have been many who do.

    DNA is a case and point - my mother swears by DNA, and yet she has no idea of the science of any of it. I do know that when people started trusting DNA testing they were convinced it was fool proof, and years later "they" admitted that there were many mistakes made as a result of primitive testing.

    In science at school we were told every couple of years to "forget what we learnt before" because essentially we had been taught simple models of the truth that were so approximated they were actually no use to anyone - that is fine, we were being taught the methods and principles of science, but when this carries over into real world scenarios, eg aerodynamics, it becomes more worrying.

    I know a fellow who is quite high up in British aerospace thingys, and did some work for the harrier a few years back etc who basically told me that the majority of their scientific research involves crashing planes, because the theory of aerodynamics is so approximated that it is practically useless to real life scenarios. It gets to the point when what kids learn in school about why a plane flies is what most people would call a lie, not even an approximation.

    Evolution is another one. The majority of western people believe in evolution, and yet I am yet to hear someone give me a really good explanation of how it really works in practice. I am not saying there isn't one necessarily, but all I have ever had through 10 years of the best schooling money could buy (the Queen paid [Smile] ) is small instances of where survival of the fittest has applied, like when a stronger twin outlives the weaker who has disabilities, therefore the stronger has lots of offspring. And yet I often hear people saying that they don't need to believe in God because we now have a scientific reason for our existance (which is silly in itself) and these people can't even coherently explain what they are now basing their life on.

    I worry about people who produce a long post and miss the earlier, simple correction. Laura pointed out correctly that he is Stephen Hawking , not Hawkins. (I have a personal interest, as it were [Razz] )

    IIRC, the doctrine he "recanted" was about expanding and collapsing universes and whether they "bounce" to produce another Big Bang. Hardly everday science, very much pushing the envelope on advanced speculation on very theoritical ideas. Stephen Hawking would be the first to admit that good science makes predictions which can be tested to verify the theory, and it is a bit difficult to test that one! Apologies to Laura that I can't find the exact reference, I have checked the four SH books in our library and can't find it in any of them [Hot and Hormonal]

    [sigh]

    Is it really that hard?

    Classic Darwinism:

    1) Organisms have more offspring than are required to maintain the species. That we are not knee-deep in guppy fish, for example, who have up to a hundred fry every month for about a year of reproductive life, shows that not all of these offspring are themselves reproductively successful.

    2) There is variation between the offspring. Some are slightly more suited, by virtue of that variation, than others, to be reproductively successful, in a world where there is competition for scarce resources (mates, food, water) and hazards (predators, extremes of environmental conditions)

    3) Those features that are beneficial to reproductive success are going to become fixed because they will be inherited from those who have them and are therefore successful parents.

    The Modern Synthesis, in brief, adds what is known about genetics:

    4) The source of variation is genetic mutation, of various kinds, that slightly change the phenotype of the offspring.

    5) Since mutations happen constantly, there is a constant supply of new variation allowing the evolution of novel features.

    And that's about it. Despite the "forget everything every two years" thing, this has actually been pretty constant since the discovery of DNA, and points 1-3 since Darwin.

    The other important points about the "Neo-Darwinian synthesis", which married natural selection to genetics, migth include:

    - any large natural population will have vast numbers of different genes in it at all times. We're all mutants. And there are billions of us. This means that (1) even quite bad genes survive for a very long time in the population and are never quite eliminated (2) there is always a supply of mutations for natural selection to work on.

    - sometimes a new gene becomes fixed in a population (i.e. nearly everyone has it) just at random. In a large population this takes hundreds of thousands of generations, so it is very rare - what tends to happen is that any gene exists in many different variants - none ever becomes universal. But in a small population it only takes a few generations, so it is quite common. So any small natural population (such as a very rare species, or an isolated population on an island) is quite likely to change its genetic composition very quickly

    A very good point.

    First, genuine scientists have both maths and the real world to keep them honest.

    Second, scientists have the constraints of mathematics to keep them honest.

    Third, scientific experiments (and knowledge) are repeatable and hence subject to independent verification.

    Fourth, good scientists (c.f. Hawking) know they are human and falliable and can admit mistakes (and if they don't, someone else will point them out).

    And shoddy statistics, but I digress.

    What probably happened there was something along the lines of:
    Scientist: No two people (other than identical twins and clones) have the same DNA
    PHB: So we could verify who someone was with a DNA test? Engineer, make me something to compare DNA.
    Engineer: Here you go. The chance of a false match is 1 in a million
    PR Person: We have a DNA tester accurate 999,999 times in 1,000,000
    Public: 1 in a million chance of being wrong sounds good to me.
    Statistician: 1 in a million chance of being wrong? There are 50 million people in the country. That means that a DNA match has only one chance in fifty of being right. Hang on, no one's listening.

    In science at school we were told every couple of years to "forget what we learnt before" because essentially we had been taught simple models of the truth that were so approximated they were actually no use to anyone

    I know a fellow who is quite high up in British aerospace thingys, and did some work for the harrier a few years back etc who basically told me that the majority of their scientific research involves crashing planes, because the theory of aerodynamics is so approximated that it is practically useless to real life scenarios. It gets to the point when what kids learn in school about why a plane flies is what most people would call a lie, not even an approximation.
    Try looking up the math sometime. It's not pretty.

    Agreed. I was simply trying to show how DNA data alone wasn't sufficient despite some rather impressive statistics that appear to come into play. And how various scientists and mathematicians knew all along, but simply weren't getting heard. I have absolutely no objection to someone extending my analogy to produce a further relevant point.

    Agreed. Science doesn't usually make progress by standing on the shoulders of giants (whatever Newton said to annoy Hooke), it usually makes progress by forming a pyramid of more normal sized people (and often squashing those on the bottom).

    hatless posted:
    As I understand it there are still issues about the speed of evolution; that the observed rate of useful genetic mutation is too slow

    As this is on-topic here, I thought I woudl reply here.

    I must make a confession. Lots of people (though few ecologists or biologists) have claimed that there is insufficient time in the world for the observed diversity of organisms to hqave been produced by Darwinian evolution.

    I have never seen any argument to that effect that made sense to me. Those that I have managed to follow have invariably seemed misunderstood the biology involved.

    Which is worrying, because one person who claimed this was the late Fred Hoyle, who was a sort of genius, and certainly an overwhelmingly better mathematician than I am (though not a better biologist I think). So it hasn't all been YECcies.

    Anyway, some guesstimates to illustrate why the argument seems silly to me.

    There are two kinds of mutation to consider - alterations within genes, and changes in the layout of genes on chromosomes (including gene duplication which is thought to be a common way of new genes emerging).

    Start with alterations within genes.

    In bacteria, populations are so large, that every imaginable point pmutation happens every generation in most populations. In fact every imaginamble combination of 2 point mutations will occur every few minutes in the E coli in your gut. Add in a bit of horizontal transmission & the supply of mutations is ovwewhelmingly gretater than that needed.

    So stick to animals (which we are interested in because we are animals). The most recent common ancestor (MRCA) of all animals is usually thought to be anythign from 500 to 1500 million years ago.

    As most animals are little wormlike things that reproduce once a year or more, lets say that 500 million generations separate us from the MRCA.

    Observed point mutation rates vary widely in different genes and different organisms. Some genes hardly change at all throughout life & have point mutation rates lower than one in a billion. Others are actively altered in every individual & have point mutation rates of about in ten thousand.

    Typical figures for protein-coding genes vary from about 1 in 1 million to 1 in 1 billion (that's point rates - the chance of one DNA base being altered - the chances of an arbitrary mutation within agiven gene is higher than that of course)

    Different versions of the "same" protein found in different animals typically have 25%-80% of their DNA sequence in common. So over 500 million generations there is simply no problem. Even if animals were asexual you might expect that sort of accumulated mutation, or more.

    As we are sexual and new combinations of genes are constantly being produced within the population, that level of variation could be driven by much lower mutation rates. In fact the high level of sequence similarity between different organisms shows how much resistance to change there is, how important selection is, and how hard it is for new mutations to become fixed. If genetic change was purely random those genes would be more different from each other than they are.

    What about between genes, chromosome rearrangements?

    Animals typically have between 10,000 and 100,000 distinct genes. For 100,000 new genes to arrive in 500 million generations is one per 5,000 generations. I think observed rates of duplication can cope with that! I have seen it suggested that gene duplications occur on averge once per zygote. mostly in male sperm, and they mostly die before fertilisation.

    If this was true the rate of new gene accumulation imples that one in 5,000 duplications is passed on to future gnerations and becomes fixed. Not a big number.

    Science is self defining and self referencing. Within this framework evolution works. It rests secure on its own assumptions. It is a meta-narrative a story that shapes our world view.

    It is a very different story to the one about the man who was God almighty hanging broken on a cross. He who bore our scars to liberate the poor and the captives. The man who stood in solidarity with the suffering to draw them into the comfort of Gods kingdom. The one who taught us that that strength is not violence but love and vulnerability. He who showed that love is stronger even than death and more glorious in its weakness than all this worlds’ strength. He who bled to liberate all creation from the chains of our sin. He who will cast down mighty from their thrones and raise the poor up when he comes in glory.

    Let us listen to the story of evolution and learn who we should be if we are true disciples. Evolution is the perfect myth of empire. The weak are to be crushed the strong survive and this is the means of creation. Out of the destruction of the weak, out of the ashes of eternal conflict arises; perfection, advancement, growth and creation.

Ah good capitalism is safe we can all be selfish greedy bastard its makes the world go round. Imperialism is safe we owe our debt to the ‘species’ our tribe. Oh and the week can get crushed.

It is not some odd notion that every word in the bible must be true but my political sensibilities and my commitment to the God of the week, the poor the lost, the God of Love and mercy which makes me think this particular story might be a bit dubious.

    Big Chaz, if I follow your little rant correctly you seem to have confused "survival of the fittest" with "survival of the strongest", and then extrapolated that to "non-survival of the weakest".

    I'm not as up on the nuances of current thought on evolution as some folks on this thread, but as I understand evolution, success is about whatever advances the survival of the species. For hyenas it can be one young sibling destroying the other before they even wean or it can be a meerkat laying down its life by being the hawk look-out for the colony. It can be a male who is attractive by carrying a prohibitively large, flashy set of tail-feathers, a tail that may make it die at a younger age than the female it mates with, or a male who beats the shit out of the rival and takes the whole pride. In humans it can involve leadership that runs a tight ship, little deviation, and which conquers other human groups and thereby earns security (it seems), or leadership that allows people to be creative and make stuff happen that benefits the rest of the tribe-civilization-world thereby encouraging people to peaceably enjoy their prosperity. All these things work to a greater or lesser degree to advance their species.

    The old dog-eat-dog simplistic version of Darwinism isn't what I think of at all. Personally I believe that if all humans could live by an intelligent loveGod-loveneighbor-loveself model it would be a pretty successful paradigm. But I ain't holding my breath since we don't come near to completely running on intelligence and love yet.

    No. Natural selection can be expected to presreve characters that give the individual organism a greater chance of leaving more offspring. (Put like that it is almost a tautology).

    There is no particular reason to think that it works for the survival of a species (or any other group) in any way other than the reproduction of the individuals.

    Anyway, here's a fun article about Avida, an evolution simulator program that takes self-replicating lumps of code, randomly modifies them and then rewards those which best carry out some arbitary task by giving them more resources. It's very interesting, and is producing all sorts of results that are getting biologists intrigued. The program has come up with artificial organisms with incredibly complex functionality, certainly way beyond anything that was expected: however, since you can go back through the logs you can see just how they came about. These things qualify as 'irreducably complex' by any of the IDers definitions - but they just happen to have evolved that way, through random mutation and selection pressures.

    The best bit of the article, though, is about creationists who (as you might imagine) take great issue with this. "Fine!" said the project people. "It's open source. Here, look for yourself!".

    As a result, loads of minor bugs have been fixed courtesy of the creationists and the program is now even better.

    Why on earth not? What's to stop a human eye evolving through many different stages by just the process I described, especially given that not only are all the intermediate stages perfectly conceivable but also exist in extant animals in nature?

    As for single celled animals evolving multicellularity - what's the problem here? There are a number of unicells that form loose colonies in some situations, and there is not much difference between this and a sponge, which can be put through a sieve and will spontaneously reform (IIRC). If these changes (all it requires is a stickier cell membrane) are advantageous, why is the process described above insufficient?

    Is this really just a dressed up argument from incredulity?

    Ultimately it comes down to a question of authority and understanding of the nature of Scripture. If you believe the Bible to be the inspired word of God, inerrant in every detail and the supreme authority, and if you believe that the Genesis account of creation is literal history (and, you can believe the first about the nature of Scripture and still consider the Genesis accounts to be a different form of literature than literal history, so the two don't necessarily follow) then you really do have to say that that authority over rides the authority of modern science. Given such a belief in the authority and nature of Scripture and the Genesis accounts, then the acceptance of the Genesis accounts as literally true is logically consistant. There is probably just enough unanswered problems with the contemporary scientific account and the Creation Science account answers just enough questions to allow Christians with such beliefs to not have to worry too much about the modern scientific account being at odds with their understanding of Genesis.

    Personally, I consider that the Creation Science side overstate the problems with contemporary scientific understandings, and don't fully recognise the weaknesses in their own version. I disagree with the understanding of Scripture as the inerrant, inspired word of God, the understanding of Genesis as presenting literal history, and Creation Science. But, I can see how people can honestly hold such a position.

    A true story for Jimbob. Some years ago, when pondering over the Genesis "literal truth" thing, my wife and I were on holiday in N Yorkshire (UK), at a place called Ravenscar, a high camping site overlooking the sea. One day we took our kids and our dog down to the sea shore - a spectacular descent of about 650 feet. The bay was beautiful, the dog ran into the sea, splashed around and came out to splash us. My eldest son, then aged seven, was examining the stratified rocks at the base of the cliff and pulled out, with some difficulty, a piece of shale from the cliff. He brought it over for us to see. The shale contained a beautiful ammonite fossil and he asked me how it had got there and what it meant.

    I remember looking up the whole height of the cliff, seeing the thousands of sedimetary layers in the cliff face and becoming deeply aware of a very simple fact of life. God is not in the business of deceiving small children. So I told my kids the truth as I understood it - that the earth was very very old and long long ago it was full of primitive creatures. One of them had got trapped in the mud and died. For millions of years, its remains had been trapped in the mud and nobody had seen them. Until that day, when my eldest son had found the rock. We were the first people to see the remains of that primitive creature since it died. My eldest son thought for moment then said "Wow dad!"

    That fossil was a very treasured possession for our children - and thirty years later we still have it. From that day, I gave up worrying about the literal or otherwise truth of Genesis.

    But here may be a helpful way to approach the problem. We cannot say "This book is right, this rock is wrong" without doing damage to truth. A reasonable synopsis of the first few verses of Genesis 1 is that God spoke creation into being. Therefore the rock, the ammonite, even the very light by which we saw it, are also ways in which God "speaks", communicates Himself to us. To claim inerrancy for the Book and duplicity for the Rock is a pretty arrogant thing to do.

    In the Purg thread "Is Creation Religious", ChristineMarie saith:

    quote:
    I do not think that evolution by natural selection as a scientific fact (aka Dawkins) to explain the whole complexity of life, should be taught in schools. Gould's position should be taught too, and those who are seeking an explanation from complexity theories.

    It seems to me that teaching natural selection as a fact for all life is to mistake science for faith, or rather, include faith with science. The faith that we will one day find all the slowly transitioning forms.

    Can I point out that Gould's position is "evolution by natural selection"? Gould's Punk Eek does not posit any new mechanism; he merely suggests that speciation - specifically - tends to happen in small populations and over geologically short time scales. The mechanism by which it does so is purely Darwinian. It is generally accepted that Gould over-egged his pudding somewhat by putting more difference between "classic" Darwinism and his model than the actual model justifies. Indeed, Darwin himself actually said that there was no reason to suppose that evolution always progressed at a similar, slow, rate.

    Can I also point out that Gould, and even Behe, believe in "slowly transitioning forms" - found or otherwise?

    And finally, can I point out that the presence or absence of transitional forms is not actually the strongest evidence of common descent, not by a long chalk? I'd rate endogenous retroviruses as a much stronger line of evidence. Since the ERVs in the human genome and the chimp genome demonstrate perfectly well that we share a common ancestor, it follows as night follows day that a number of intermediate species must have existed between the last common ancestor and both chimp and man, whether we have the fossils on display at the British Museum or not.

    I have Gould's Big Book on evolutionary theory, which is a heavy read and I am not very far through it yet. (He seemed to have intended it to be his last testament - its huge, discursive, and highly opinionated)

    But he's very very clear that he is within the "Darwinist" camp. And in fact that he doesn't really think there is any other camp to be in.

    A brief thought, which I heard from one of the preachers at our college chapel last term:

    'If scientists look at God and see nothing, is it possible than when scientists see nothing it is because they are looking at God?'

    Not a full explanation by any means, but possibly a means of bringing God into, for example, natural selection, and the steps we can't see, as well as many other unexplained phenomena.

    Of course, the danger of this is that as we come to understand various scientific phenomena, we start to feel we don't need God to fill the gaps, which is very dangerous

    I think that people will always see what they want to see. An evolutionist and a creationist may look at the same piece of evidence and come to completely different conclusions.

    To demonstrate,
    1, Go into the next room and remember all the things in the room that are red. Come back and see how many you remembered.


    2, Then without going back and looking, name all the blue things in the room.


    3, Go back and check your answers.

    If the excercise has the desired result you would have been able to remember many red items and only a few blue ones in spite of what the actual red/ blue ratio was.

    Perhaps both creationists and evolutionists cling in 'faith' to pre-conceived ideas and scientists are by no means the impartial observers they like to think they are.

    One of the reasons that people learnng science go through rituals like taking courses in statistics (hard to avoid, I'm on my third) is precisely because everyone involved realises that perceptions are biased and observers are not impartial, so they try to train people to make transparent analyses of observations.

    I'm not that much of a scientist but almost the first thing you learn when studying the basics of electricity is that the equipment you use to measure whatever property you are interested in alters the thing being measured.

    You can work round it and adjust readings accordingly but if you don't understand that, you wouldn't know that your readings needed adjusting.

    Same applies to using rulers etc to measure phyical things, but not often on such a scale.

    An additional point. The nature of scientific inquiry is that it proceeds by replicable experiments and findings and peer review. Briefly, results are exposed to the air, can be checked and verified or challenged. This process is not perfect but does eliminate virtually all imperfect observation or inbuilt bias in experiments.

    In the Darwinian context, the evidence which underlies the hypothesis is ubiquitous and the means of evaluating the age of the evidence very well attested. Anyone can look, anyone can replicate/check/seek to report anomalies/false findings.

    Even Creation Scientists. I don't know of any examples (and if there were I'd expect them to have been trumpeted loudly), but there's no reason why a Creation Scientist reading a paper can't spot and report a genuine flaw in it. Which means that, in that instance at least, the Creation Scientist is doing good science despite any religious opinions held.

    Karl, I agree with you and Alan. You can enter the process as an athiest, a member of any faith community, with whatever presuppositions you've got. The process is indifferent to all of that.

    I'm not sure of the details but I think a well respected figure stepped back from the current notions of evolutionary development prior to the appearance of single cell organisms (a subject about which I am very ignorant. Apparently he decided the ideas didn't "fly". Score one for Intelligent Design? Not really. He's just one guy expressing an honest view on the basis of the evidence. It isn't "life or death" for him.

    The hardest thing to get across about scientific enquiry is that ideas move in response to findings. That makes scientific enquiry a humble and tentative process, always open to revision. It does not deal in certainties, it deals in "best availables". And it is open to surprise. I like it.

    OK, I'm responding here to avoid taking the other thread any further into the Dead Horse graveyard.

    In science (biological sciences in particular), "evolution" has only one meaning. It's shorthand for the development of new species through the process of natural selection acting on populations of creatures which display a range of variations for selection to act on, coupled to genetic mutation as a source of new variation. It is an extremely successful description of the process whereby the observed current (and fossilised) diversity of life on this earth developed over time.

    Some people, including it seems many Creation Scientists and other popularisers of various forms of Creationism, use the word in other ways that do tend to result in a certain amount of confusion.

    Though astrophysicists and cosmologists use the word to describe the development of the universe and the stars and galaxies within it, that is a different theory - it has no natural selection or mutation element (though it has been used in some highly speculative hypotheses relating to bubble universes within a multiverse).

    Nor does biological evolution describe the origin of the first self-replicating organisms, the DNA code etc. It also doesn't describe the processes of human cultural development (despite the highly speculative hypothesis of "memes") where much of that development couldn't realistically be described as "natural".

    And, to use "evolution" as a shorthand for a fully materialistic atheistic view of science is a really big stretch for the word. Not that it stops someone like Duane Gish from using the word in that sense.

    Not sure if this is the place to post this, but I figure if I put it in Purgatory I'd be told it was Dead Horse territory, so I'm asking here.

    An Answers in Genesis guy is coming to our church the week after next to give a seminar on creationism. Here's his bio:

    quote:
    Dr. Silvestru was once himself an evolutionist but after a conversion experience he began to explore the creation story -- what he found convinced him that the Bible is accurate and that the study of science confirms it.
    Now, I've always been a bit uneasy with 6-day young-earth creationism, which is officially part of What We Believe in our church. But as I'm not in any way a scientist (not even as much as my engineer husband, who I've just learned from reading this thread is no more a scientist than a bricklayer is an architect!!), I don't really have the knowledge, vocabulary, or interest to engage in the Creationism debate at any meaningful level. My attitude has always been that I know God created the world and I'm not particular bothered about when or how He did it.

    However, when it gets to the point of making a belief in YEC a test of faith and fellowship, I get a bit squirmy. And I have a very bright science-minded 7 y.o. who is learning different stories about origins at church and at school and will probably want some more clarificationat home than my own fuzzy philosophy is able to provide.

    So, if you were a bit of a liberal in a conservative church, with no real science background beyond 1st-year university biology 20 years ago, what intelligent questions would you post to the "Answers in Genesis" guy during the "question and answer" time? I know there's a huge amount of contempt around here for AiG, ICR, etc., but if you were in a room with a "Creation Scientist" in this kind of setting, what would you ask?
     
    Posted by Zeke (# 3271) on :
     
    I'm not a scientist either, but I was brought up as well in a literalist church. What started me being skeptical at about age 12 was nobody being able to give me any decent explanation of how they reconcile the two different versions of the creation in Genesis. It was as if I were terribly tasteless and crude, as well as suspect theologically(or however you say it) for even bringing it up. My first question, if he really says he believes Genesis literally, is which version is the right one. Read them both carefully first, taking note of the totally different details in the sequence of events, so you will know if he is just trying to snow you. I've never yet been given a decent answer to this from anybody who says they believe Genesis literally.

    Perhaps, though, more knowledgeable people who post here can come up with something much better, which is entirely possible.

    Not quite an answer to the question, but I'd suggest reading through the various pages of TalkOrigins, before the question and answer session. The site's list of "Must-Read" files is here, and unfortunately, it's kind of long. There's a page called Stumper Questions for Creationists, although if you are dealing with a practiced charlatan, he might have answers for those questions. They'll be wrong answers, of course, but they'll probably sound good enough that the proper rebuttal won't be immediately obvious. [Frown]

    I would think carefully before trying to 'debate' or 'stump' one of these pseuds as an amateur. Their strength actually lies in their use of rhetoric

    debating creationists

    It's much harder to refute nonsense than you think. I often deal with their historical equivalents who spraff nonsense about templars and holy grails. They can throw out pieces of nonsense off the cuff which would take a specialist hours of research to refute, because they don't care about making claims which have little or no evidential basis. The key seems to be to familiarise youself with what they are likely to come out with beforehand. I'm not sure what to recommend - have you thought of PM-ing Alan Cresswell to see if he has any ideas?

    I have all sorts of problems with the concept of debating publically with AiG type people. The last time I went to such an event I spent a couple of hours over lunch with one of the speakers discussing one particular issue in detail (that was about one aspect of 14C dating) and followed it up with an email exchange. In the public meeting there simply wouldn't have been a chance to do that.

    I would go in with one point to make, and one point only. Don't go in to try and prove his science wrong (he'll almost certainly have ready answers for anything you can throw at him). I would go in with the intent of getting him (and, more importantly others) to recognise that YEC can't be held as a test of orthodox belief. Do some research, find some big name evangelicals (stick to them, you don't want to get sidetracked into are non-Evangelicals orthodox believers) who don't accept the YEC theory and ask if he thinks they are true believers.

    Louise has it. AiG are as slippery as an eel. Some professional creationists, like Kent Hovind, are even worse, firing out a series of quick soundbites that they claim disprove mainstream science, each taking a couple of seconds:

    "Did you know that human blood proteins are closer to those of the butter bean than of the chimpanzee?"

    and which would take several minutes - and documentary evidence - to refute. The trick here is that the creationists always do their talks to home audiences - who will accept their claims without any supporting evidence (because (a) they trust a fellow Christian and (b) they want to believe what he's telling them) but be extremely sceptical of evidence pointing the other way.

    Case in point - I seem to recall that both Duane Gish and Kent Hovind have spouted the above piece of bullshit. Neither of them have ever managed to quote a source for it - hardly surprising, given that butter beans tend not to have blood at all. But how does the mainstream scientist, suddenly presented with a supposed fact like that, convince a hostile audience? He can't, and the creationist grins smugly.

    Which is why I find it useless to argue science with them. If they presented their stuff at a scientific meeting they'd never get away with it - repeated "can you provide a reference for that?" without an adequate answer will ensure what little respect they may have started out with will quickly disappear. In most church environments there are simply not enough trained scientists to follow up adequately on such things, and most people would be simply bamboozled by scientific sounding language and reference to papers in the "Technical Journal". In that situation a single scientist tackling an issue of, relatively obscure, scientific data will appear as a lone crusader and most people will turn off as the conversation goes over their heads - that's why the last time I was at such a meeting I waited around after the morning session to tackle the speaker privately.

    In a church environment I would be much more comfortable confronting them on theological issues. Which is why I suggested asking them why YEC is vital for Christian belief - you'll then be discussing Biblical texts and Christian doctrine which even though it won't change the speakers mind will at least be intelligable to a large number of others there. And, generally, AiG tends strongly towards YEC being an essential Christian belief; their site contains numerous "relevance of Creation" or "how to convince a Christian of the truth of Creation" type articles. On this issue, at least, I agree with Gordon, it's no more than a sidetrack, a peripheral issue on which Christians disagree (with the vast majority of Christians rejecting YEC).

    Interestingly when I first became a Christian it was in the sort of environment where I thought I had to be a YEC to be a good Christian.

    What changed my mind was going to one of those show debates. I came expecting to cheer the creationist (Gish or one of those), and ended up coming away thinking what an uncharitable bastard he was, and how slanted and indeed twisted his presentation was. That got me doing a little more research on the whole issue, which resulted in me ending up where I am today, firmly in the old earth evolutionist camp. The creationist, of course, "won" the debate -- there was no way he couldn't, as Alan has pointed out -- but lost the war!

    So for any evolutionist thinking of doing such a debate: it's not as hopeless as it seems!

    A large part of the reason I stopped being a YECist was that so much of the evidence they presented was poor physics. Some wasn't and isn't. I'm still officially agnostic on YEC...

    I had an e-mail debate recently with a YECist who is a lecturer in physics at a red brick British university, about radioactive dating and the nature of the Flood as described in Genesis, as it so happens.

    It's a much better forum for doing stuff than up front - allows you to go away and try a few calculations for one thing. In this case, to demonstrate that the gaseous argon inclusions in the lava, while they might produce huge errors in recent rocks, made virtually no difference to the dating of older rocks. Simply seeing a prominent (and physics literate) YECist use an argument that was that easily dismantled made me doubt their position even more.

    It's like those people who say the Bible is full of errors, and half the things they come up with are obviously not errors (like which women were are the cross). The fact they use such arguments strongly suggests they don't have better ones.

    It simply means that the Jews meant something slightly different by "chewing the cud".

    It is not necessarily immediately obvious that the others are spurious, but it usually becomes clear after a bit of reading of the relevant passages.

    But then, maybe Deuteronomy means something different by "hoof", too or any of these:

    quote:
    These are the animals you may eat: the ox, the sheep, the goat, the deer, the gazelle, the roe deer, the wild goat, the ibex, the antelope and the mountain sheep.
    If the words don't mean what the words usually mean, the meaning of the passage is purely subjective.

    The celebrated NT example (which caused Calvin, of all people, a certain amount of wry amusement) is the passage where St Matthew attributes to Jeremiah a prophecy made by Zechariah.

    That's not fatal for the more nuanced form of inerrancy ("in matters of faith and morals") but it kills stone dead the view of inspiration that says the writers of sacred scripture were unfaillingly right about everything.

    Which is a bit of a tangent from YEC vs Darwin debates which are essentially about genre. YEC says that Genesis is essentially the same sort of thing as a science text book. Those of us who accept the theory of evolution say that it is the same sort of thing as a parable or, more grandly, the Divine Comedy. The question is not: "Is Genesis true?" to which both sides baldly answer "yes". The question is: "Is Genesis a literal and factual account of the creation of the world" to which YECs answer "yes" and the rest of us say "no".
     
    Posted by Barnabas62 (# 9110) on :
     
    And for those who are not sure, the passage is Matt 27 v 7-9 and its prophetic parallel is not in Jeremiah, but in Zec 11 v 12-13.

    And, for good measure, there is a similar error in Mark 1 v 2-3. He attributes both verses to Isaiah, but verse 2 is Malachi 3 v 1.

    And I entirely agree with Callan that although this strictly belongs in the Inerrancy Dead Horse, there is a close link to Death of Darwin thinking. It is the same mode of thinking which "must" devalue Darwin, which also "must" protect scripture from any accusation of inerrancy. Evidence points one way - belief another - so which wins? Depends on how much you really value truth.

    Making it clear what I meant by that. There's nothign wrong with seriously talking about science - but in the context of what sounds like a staged presentation to convince the half-convinced, where scientists are assumed to either be absent or, in a "debate", just present in order to be held up for mockery, there is probably little chance of any serious talking being heard.

    It would be like trying to sell Pepsi at a convention of Coke salesmen.

    So talk about Jesus, not butter-beans.

    Though if someone does bring up butter-beans you could always point aout as condescendingly as possible that they don't have blood.

    (They do have something very like haemoglobin though - just like all the other beans do - in their root nodules - part of the wonderfully complex nitrogen-fixing symbiosis which involves plant and bacteria genetically engineering each other...)

    Posted by TrudyTrudy (I say unto you) (# 5647) on :
     
    Well, I'm back in one piece from the Answers in Genesis seminar. The speaker was taking up a 2 p.m. - 5 p.m. block of time this afternoon and about 7 - 9 p.m. this evening; I was only able (or willing) to be there from about 3:30 - 5:00, which was plenty. I got his presentation on the Flood and dinosaurs, and the Q&A session, where I asked two Q's.

    At one point during his presentation he made the comment that no-one is unbiased, everyone looks through some pair of "glasses" (true enough) and that there are only two pairs of glasses -- the belief that God created everything just as it says in Genesis, and the evolutionary belief that excludes God. At least, I thought that was what he said. I tried to repeat it back to him during question time, adding that as I understood it there were lots of Christians who believed in God but also in evolution. He said that wasn't what he'd said exactly: when he rephrased his point this time, it came out that you could either believe in a worldview in which God was the Creator, or one in which there was no God. He admitted that if you believed God was the Creator, you could then believe in young-earth creationism or an old earth, but that he thinks that Christians who don't believe in YEC are not being logically consistent in their views. He also believes that such Christians' "compromise" with secular science is responsible for the fact that 75% of youth raised in evangelical homes and churches end up leaving the church (because the science they are taught in public school conflicts with the faith they are taught in church; he believes Creation Science can remedy this bit of cognitive dissonance and keep our kids in church). He did, however, say (without my specifically asking the question) that he does not believe that Christians who believe in evolution will be eternally lost. (Whew!)

    Later, I asked him if he believed that just this planet had been created in 6 days, 6000 years ago, or did he believe our whole solar system, or the entire universe, was also created then? He said everything, the universe, the whole she-bang. I asked about the distance light travels, etc., and he responded with some technobabble I didn't understand. But I thought it was interesting that he was presenting this view in an SDA church in front of an audience that was just lapping it up, because while SDAs have traditionally been YECs, our theology has also always assumed the existence of the rest of the universe and of inhabited, unfallen worlds long before ours was created ... so I wonder if my asking that question created any questions in anyone's minds. Apparently AiG takes the same position as ICR ... no other life in the universe at all. He also said earth was the centre of the universe and he was going to demonstrate that in tonight's presentation -- not sure if he meant literally or metaphorically.

    As always when I'm exposed to Creation Science, I find some of the theories and explanations (re the Flood etc) intriguing to my non-scientific mind, but the dogmaticism (and the attitude of contempt and ridicule for scientists who believe in evolution ... did not realize how bad that was until I saw it live) made me even less of a YEC than I was when I went in there.

    Trudy, included in the many things I dont know is the meaning of SDA. I'm sure this must seem very ignorant but will you enlighten me please? (Or someone else).

    Most technobabble by YEC about universal creation 6000 years ago is a variation on the "Adam's navel" argument. Adam didn't need a navel because of the way he was made, but most artists show him as having one, otherwise he would be a funny looking human being. So, the argument goes, the universe could have been created with an apparent history, based on natural appearances, because in God's creativity, it would have been incomplete without that appearance - just like a non-navelled Adam would have been incomplete. Throw in a bit of stuff about variations in the speed of light and there you go.

    No one ever seems to tackle the issue of why God should have made such an apparently deceptive universe, not accessible to "plain meaning" interpretation, and still called it "good". "Ah, God's thoughts are not our thoughts" is as good as it gets. If you get another chance, try taking the moral highground on the deception issue! IME it has disconcerting effects.
     
    Posted by Lyda*Rose (# 4544) on :
     
    That's why Creation Science can't be science in any modern meaning of the word. If God can and does do things arbitrarily without apparent system then nothing can be deduced from scientific evidence. Things may work in one way now, but worked in another 6,000 years ago. The speed of light could have been faster, slower, or instantaneous at God's whim. He might have thought it a lark to put stones in the ground that looked like bones of animals that never existed. Whatever. God's mind is not our mind, so that should cover most bases. Why bother to think it out? In the Creationist's world pre-history is bunk. [Roll Eyes]

    That is a valid argument. Scientifically it's not open to dispute. As you point out it does raise a number of theological questions about whether God would do something so deceptive and the like.

    But, "Creation Science" doesn't hold such a position. All the "technobabble" about changing speed of light, radioactive decay rates etc. isn't saying "God created the universe with an appearance of age, and science is correct in how it describes the universe except that it can't tell the difference between an apparent age placed there by a perfect omnipotent Creator and an actual age", but that "God created the universe without an appearance of age, but that science has got it wrong in ascribing a great age to the universe on the basis of the evidence. Look at the evidence closely enough and you'll see that actually it points to a young universe"

    Alan, thanks for the update. Your information is scary. So this is how creationist views have "developed" since I read them in detail a few years ago (and despaired). I'd better have a closer look at the more modern arguments then - at least the old "Adam's navel" variations had a little integrity, as you point out.

    Trudy - two apologies. Firstly for not spotting SDA - its obvious now I see it. Secondly for misleading over the underlying basis for "creation science" today. Alan is (nearly) always right on these things.

    Oh, its an interesting article, it just doesn't tell us anything about birde being dinosaurs, because we knew that already.

    The idea that birds are dinosaurs is over 150 years old - Robert Owen promoted it IIRC. It was widely accepted in the 1970s. I remember it from classes at both school and university - I particualry remember the A-level lesson when the teacher explained the difference between a clade and a grade and pointed out that birds are more closely related to crocodiles than either are to any other living group. IIRC it was in JZ Young, the standard zoology textbook of the 1960s and 70s. It was certainly the general view among paleontologists by the late 80s. Not that that makes it true of course, but it does mean its hardly news.

    I did a short palaeontology course in 1999/2000 and read quite a lot of the recent literature on this. It was already quite standard for books and papers to refer to "non-bird dinosaurs". Baby dinosaurs were routinely called "chicks". (I even heard the phrase "fluffy Tryannosaur chick" once) There was speculation that T. rex and similar were possibly secondarily flightless - descended from things like ostriches.

    The real fossil action these days is coming from China. Little dinosaurs that probably lived in trees. With feathers. Very plausible relatives to supposed ancestors of modern birds.

    An interesting speculation about eggs - it seems that dinosaur eggs had chalky shells like modern birds eggs do. And this is important to their calcium metabolism. This has been suggested as a reason why (as far as we know) there have never been any fully marine dinosaurs. They can't go viviparous and so they have to go back to land to breed. Lizards and snakes have returned to the sea at least three times, and mammals once or twice, never needing to go back to land at all. But not dinosaurs, including birds. (Or crocodiles either - its an archosaur thing)

    This is the "strongest ever link" showing birds and dinos are very closely related. The medullary bone discovery is new and only found in birds, according to the article.

    Very open - the bird clade (or possibly clades) is entirely included in dinosaurs, so if Dinosauria is a valid name it applies to all birds.

    In reality that means keeping the faithful dependent on their every word and discrediting any contrary voices, even when those voices wish to argue on scientific grounds. Let’s parse Rex Monday’s recent post to see how it is done.

    So, on the one hand scientists are an unassailable godlike elite and therefore bad. On the other hand ID is science and therefore good. Rather neatly Faithful Sheepdog has encapsulated the duality of ID which on the one hand taps into anti-scientific sentiment. On the other hand it wishes also to borrow such prestige as science posesses for its theories. Of course, if ID is a scientific theory its proponents are scientists and therefore as much prone to elitism and delusions of grandeur as Dawkins et. al. but I'm sure the fact that ID theorists are such good Christians defends them from that temptation.

    If you could find a theory if ID, suggest a theme that could be researched or say what predictions ID makes -- all aspects of science -- then you'll be doing better than other ID proponents.

    Note the character assassination and the broad brush slur. Apparently, ID supporters do not engage with their critics. They are clearly disreputable people whose ideas contain nothing of merit. And they certainly don’t do research and produce predictive hypotheses.

    It is unclear whether Rex Monday has ever heard of John Davison’s Prescribed Evolutionary Hypothesis, or Walter Remine’s Biotic Message Theory, or the research on the subject of Endogenous Adaptive Mutagenesis (EAM). These people thought they were doing scientific research and producing falsifiable scientific hypotheses, but no, the high priests and their acolytes say otherwise.

    The three theses you cite sum up Rex's point admirably. Davison postulates that the evolutionary development of a species is somehow pre-ordained rather than determined by natural selection, an idea which can be simply dismissed by the two words "mass extinction". Remine's thesis is the subject of a laudatory review in Answers in Genesis. The final thesis, EAM appears to be nothing more than warmed over Lamarckism, a theory that has been consigned to the rubbish heap long ago.

    It's his consequent arguments, that this could therefore not have evolved, which are contentious - actually, plain wrong. But creationists (and I emphasise once again that IDers are indeed creationists, although you'll have to do better than I to find out whether they're YECs or another flavour. They *hate* answering that sort of question) either lack the wit to understand the fact that IC is not by itself creationism/ID, or deliberately confuse the two.

    Here we just get vicious slurs against a whole class of people. Rex Monday cannot limit himself to saying that ID ideas are seriously mistaken. He has to confuse the whole ID issue with furthers ad hominem attacks on “creationists”. Note the standard tactic of guilt by association, not to mention a nice piece of emotional projection - it’s now “hate” when someone objects to misrepresentation.
    The word 'hate' can be used in English with a variety of nuances from 'Hitler hated the Jews' to 'I hate Pumpkin soup'. I think Rex's use of the word in this context is as legitimate as the use of the phrase "vicious slurs against an entire class of people" which is rather more melodramatic than anything Rex has posted.

    Rex Monday said:
    You do know that Behe has said that the mechanism of ID is a puff-of-smoke miracle, don't you? And that Dembski has said that his maths is a distillation of the theology of John's gospel? "The world is a mirror representing the divine life. The mechanical philosophy was ever blind to this fact. Intelligent design, on the other hand, readily embraces the sacramental nature of physical reality. Indeed, intelligent design is just the Logos theology of John's gospel restated in the idiom of information theory" (Touchstone, July/August 1999).

    And here we get the pièce de resistance. It is the most blatant use of a double standards yet, and an excellent example of selective quote mining.

    The YEC world has been rightly and heavily chastised for its use of selective quotations taken out of context. In this way an author can be made to appear to support a position to which he is in fact totally opposed. It is a widely condemned practice that is completely unethical, but not, it seems, in the hands of the high priesthood and their acolytes.

    You’ll find that Behe’s comment about a “puff of smoke miracle” was made with a smile on his face and a twinkle in his eye. It was a deliberate wind-up of certain people, and he’s obviously succeeded. No doubt he was equally trying to wind people up when he wrote his book and the detailed scientific articles in response to his critics.

    Dembski’s comment on logos theology reveals no more about the scientific merits of his ID work than did the comment of my A-level (British school exams at age 18) maths teacher, who termed a certain class of integrals as “Act of God” integrals. His religious viewpoint didn’t stop him teaching us the maths, nor me passing my A level. Dembski’s article about ID in the Oxford Handbook of Religion and Science makes his own position crystal clear.

    Really, Neil, it is terribly disingenuous to complain that accusing Intelligent Design theorists of letting their religion drive their science is somehow the culmination of a vicious crescendo of hate. Intelligent Design is about putting God back into science, about arguing that the scientific method breaks down when we examine the mystery of life forcing us to acknowledge the existence of a creator. That is its central message, its raison d'etre. The Discovery Institute website, for example, contains all sorts of stuff about how Darwinism is ultimately subversive of our Judaeo-Christian heritage. This is another example of ID duality which wishes on the one hand to claim that it is objective and neutral science and, on the other, that it is protecting the morals of our children and servants from atheistic Darwinian evolutionists. Behe may have had a twinkle in his eye when he made his remark about a puff of smoke miracle but central to his thesis is the notion that there is a level of complexity which can only be explained by reference to supernatural intervention. I thought that was the point. The link you provided for Dembski comes courtesy of the Southern Baptist Theological Seminary. The idea that ID is motivated by studied neutrality about religion is, frankly, rubbish. ID is a Christian enterprise designed (boom-boom) to get round American sentiments about the separation of Church and State and powered by anxiety about Darwinism being subversive of Christianity. Getting cross about it doesn't alter that fact in the slightest.

    Here's my very simplified understanding of ID.

    There are somethings in science (origin of life from non-life, certain biological systems etc) that we can't explain how they happened by current science. They appear to have the marks of design.

    The atheist scientist says "there's no designer, therefore they can't be designed. Let's continue studying them, learn a bit more, and eventually understand how it happened."

    Most scientists hold some form of religious view or are agnostic. They say "there may, or may not be a designer. And, if there is a designer he may, or may not, have done something miraculous to cause this. We don't know, indeed we can't know. So lets get on with studying it as though there was no designer."

    The out-and-out YEC would say "God did that 10000 years or so ago."

    The IDer says, "God did it, though not 10000 years ago because that's too religious to mention in a science class. But, he did it. And, as he did it there's not much more to say about it." Many IDers recognise that if you do that then you might as well give up on science as soon as something becomes difficult. They then fall into a logical falacy and say "Darwinism says God didn't do it," (which is wrong, BTW, Darwinism isn't incompatible with "God did it"), "we know that God did it. Therefore we'll come up with whatever alternatives to Darwinism we can find to offer alternative explanations. Never mind that those explanations have long-since been disproved, or are far more speculative than Darwinism. So long as they provide an alternative in which 'God did it' they're clearly better."

    Thanks, Callan - I didn't have time before this evening to give the latest trial by Sheepdog a going-over, and I have little to add to what you said except I'm glad that it's not just me who thought I was woefully misrepresented in the reply.

    However, there is one point I'd like to expand, just for the record. Here's what Dembski says in his 'crystal clear' explanation of why ID is science and not religious that FS quoted before retiring hurt.

    quote:
    It follows that the charge of supernaturalism against intelligent design cannot be sustained. Indeed, to say that rejecting naturalism entails accepting supernaturalism holds only if nature is defined as a closed system of material entities ruled by unbroken laws of material interaction. But this definition of nature begs the question. Nature is what nature is and not what we define it to be. To see this, consider the following riddle: How many legs does a dog have if one calls a tail a leg? The correct answer is four. Calling one thing another thing doesn’t make it something else.

    Likewise, defining nature as a closed system of material entities operating by fixed laws of interaction doesn’t make it so. Nature is what nature is, and prescribing methodological materialism as a normative principle for science does nothing to change that.

    ID theorists argue that methodological materialism fundamentally distorts our understanding of nature. In assessing
    the validity of ID, the crucial thing is not whether they are right but whether they might be right.

    Given that they might be right, methodological materialism cannot be taken as a defining feature of science, much less should it be held dogmatically. To make methodological materialism a defining feature of science commits the premodern sin of forcing nature into a priori categories rather than allowing nature to speak for itself. To sum up, methodological materialism presents us with a false dilemma: either science must be limited to “natural explanations” (taken in a highly tendentious sense) or it must embrace “supernatural explanations,” by which is meant magic. But there is a third possibility: neither materialism nor magic but mind. ID theorists are not willing to concede the materialist claim that a designing intelligence (mind) interacting with matter is “supernatural.” Indeed, investigations by ID theorists are beginning to demonstrate that this interaction is perfectly natural — that nature cannot be properly understood apart from the activity of a designing intelligence (cf. Schwartz and Begley 2002).

    I must admit immediately that I don't find this crystal clear - quite the opposite.

    Dembski seems to be redefining 'natural' to include the actions of some mind external to the 'closed system of material entities operating by fixed laws of interaction', and then saying that because this happens, it's science. It's hard to be sure what he's saying, though, because although he says that the 'closed system of material entitites...' etc is insufficient to define nature, he never then gives a definition in its place. Sure looks good enough to me.

    This looks like vacuous rhetoric that dismisses the fundamental tenets of science without proposing a usable alternative, while proposing a religious definition lightly cloaked under 'Neither materialism nor magic but mind'.

    What 'mind' might that be, then, given that 'calling one thing another thing doesn't make it something else'? And how does its invisible manipulations of the laws of physics count as anything other than 'magic' or 'supernatural'?

    I was looking forward to hearing an explanation of what the above actually meant, and why Dembski's vision of a 'designing intelligence interacting with matter' in ways that are outside our 'fixed laws of interaction' is any less religious or more scientific than the Virgin Birth or the Resurrection.

    I guess we'll never know.

    If you aren't well enough to engage in debate, may I suggest you don't post 1,200 word contributions which may give a different impression? This isn't the first time that you've started a conversation you've been unable to finish, and it appears to make a debilitating illness worse.

    I would further suggest that if and when you feel well enough to return, you desist from words like 'snide', 'ill informed', 'character assassination', 'blatant use of [a] double standards' and so on, in Purgatory or in here.

    I don't care what you call me, but there are rules and I think we should stick to them. If you want to accuse me of such things, call me to Hell. Perhaps, however, it would be better if you took a break for a while.

    The problem, Sheepdog, is their predecessors in those high places were not very nice to previous scientific truth-tellers like Galileo. To have friends in high places is not normally a very secure test for the veracity of an idea.

    I'm not sure that quoting an RC Cardinal Archbishop is a good ploy when trying to demonstrate that ID isn't religious, especially one who also seems to misunderstand quantum physics. It might seem somewhat counterproductive, in fact.

    Are you now well enough to continue the discussion, then, or will asking you this question -- and asking you to attend to the previous questions so far ignored -- provoke your illness?

    I don't want to come across as one of those shrill posters who harps on about the same old boring things, but at the moment it is impossible to continue with this discussion unless you're able or willing to do so properly.

    Pope believes in God shock! Whatever next?

    I should keep the Champagne in ice tho' O Faithful one. This pronouncement by the Vatican (approved by Pope Benedict in his old job) on evolution, whilst containing a benevolent nod to Intelligent Design suggests that it is not about to be declared a dogma of the Universal Church any time in the immediate future. The whole thing is worth a look but the key paragraphs are.

    quote:
    68. With respect to the evolution of conditions favorable to the emergence of life, Catholic tradition affirms that, as universal transcendent cause, God is the cause not only of existence but also the cause of causes. God’s action does not displace or supplant the activity of creaturely causes, but enables them to act according to their natures and, nonetheless, to bring about the ends he intends. In freely willing to create and conserve the universe, God wills to activate and to sustain in act all those secondary causes whose activity contributes to the unfolding of the natural order which he intends to produce. Through the activity of natural causes, God causes to arise those conditions required for the emergence and support of living organisms, and, furthermore, for their reproduction and differentiation. Although there is scientific debate about the degree of purposiveness or design operative and empirically observable in these developments, they have de facto favored the emergence and flourishing of life. Catholic theologians can see in such reasoning support for the affirmation entailed by faith in divine creation and divine providence. In the providential design of creation, the triune God intended not only to make a place for human beings in the universe but also, and ultimately, to make room for them in his own trinitarian life. Furthermore, operating as real, though secondary causes, human beings contribute to the reshaping and transformation of the universe.
    quote:
    69. The current scientific debate about the mechanisms at work in evolution requires theological comment insofar as it sometimes implies a misunderstanding of the nature of divine causality. Many neo-Darwinian scientists, as well as some of their critics, have concluded that, if evolution is a radically contingent materialistic process driven by natural selection and random genetic variation, then there can be no place in it for divine providential causality. A growing body of scientific critics of neo-Darwinism point to evidence of design (e.g., biological structures that exhibit specified complexity) that, in their view, cannot be explained in terms of a purely contingent process and that neo-Darwinians have ignored or misinterpreted. The nub of this currently lively disagreement involves scientific observation and generalization concerning whether the available data support inferences of design or chance, and cannot be settled by theology. But it is important to note that, according to the Catholic understanding of divine causality, true contingency in the created order is not incompatible with a purposeful divine providence. Divine causality and created causality radically differ in kind and not only in degree. Thus, even the outcome of a truly contingent natural process can nonetheless fall within God’s providential plan for creation. According to St. Thomas Aquinas: “The effect of divine providence is not only that things should happen somehow, but that they should happen either by necessity or by contingency. Therefore, whatsoever divine providence ordains to happen infallibly and of necessity happens infallibly and of necessity; and that happens from contingency, which the divine providence conceives to happen from contingency” (Summa theologiae, I, 22,4 ad 1). In the Catholic perspective, neo-Darwinians who adduce random genetic variation and natural selection as evidence that the process of evolution is absolutely unguided are straying beyond what can be demonstrated by science. Divine causality can be active in a process that is both contingent and guided. Any evolutionary mechanism that is contingent can only be contingent because God made it so. An unguided evolutionary process – one that falls outside the bounds of divine providence – simply cannot exist because “the causality of God, Who is the first agent, extends to all being, not only as to constituent principles of species, but also as to the individualizing principles....It necessarily follows that all things, inasmuch as they participate in existence, must likewise be subject to divine providence” (Summa theologiae I, 22, 2).
    The Vatican's point is that whether the Darwinians or the ID people are right is immaterial from the point of view of Catholic theology which maintains that God is providentially involved in the whole of creation, not just those bits which ID theorists believe Natural selection couldn't account for.

    Good to see you off your bed of sick, btw.

    I think you will find that the RC church's persecution of Galileo was a political matter rather than a strictly scientific one. But even if I accept the alleged historical perfidiousness of the RC church, it does not logically follow that the contemporary RC Church cannot accurately discern the truth (or otherwise) in scientific matters today.

    Rex Monday:

    Please comment on the issues. Feel free to do so with or without my presence on this thread. Please substantiate your comment on the Archbishop's misunderstanding of quantum physics.

    Callan:

    Thank you for your good wishes and for the link. I have printed out the Vatican document for further detailed study in due course.

    My initial response is that this is clearly a theological and philosophical statement rooted in RC theology and philosophy. ID is a scientific outlook and I would no more expect the various ID approaches to be become RC dogma than any other scientific hypothesis or theory.

    However, I am pleased to see that the writer of this document is clearly familar with the ID world and some of its terminology. For me the key phrase in paragraph 69 is:
    quote:

    "...cannot be settled by theology" is a comment with which the ID world would wholeheartedly agree. That is why the the debate needs to focus clearly on scientific issues.

    The problem is that for most scientists "...cannot be settled by current science" is also a reasonable response to the ID claims. The situation seems to largely (if not exclusively) settle around a number of test cases that current science has no explanation for - the question being does the lack of explanation reflect the deep truth that there is no scientific explanation (it was designed like that), or merely reflect scientific ignorance. While current science has so much that falls clearly within the "scientific ignorance" category, it doesn't seem at all unreasonable to assume that the issues in question also fall into that category.

    ID is not a scientific outlook. For one thing, it is completely unfalsifiable and for another it revolves around argument from ignorance (I don't understand how that happened, therefore no one understands it therefore Goddidit).

    ID revolves round a God of the Gaps, and assuming an answer from a lack of evidence rather than an attempt to find out how things happened.

    FS-

    I rather thought I was commenting on the issues, but so far I fear I've only garnered a collection of rather unpleasant epithets for my trouble.

    However, glad to see you're better. Any chance you could forgive my 'inability to understand plain English' and address _any_ of the issues raised about the unscientific nature of the articles you referenced earlier by way of demonstrating the scientific nature of ID?

    In particular, your 'crystal clear' article by Dembski that I couldn't understand. As I said earlier:

    quote:
    I was looking forward to hearing an explanation of what the above actually meant, and why Dembski's vision of a 'designing intelligence interacting with matter' in ways that are outside our 'fixed laws of interaction' is any less religious or more scientific than the Virgin Birth or the Resurrection.
    So, how _does_ Dembski's explanation show that ID is science rather than religion? A simple paraphrase in your own words would be an interesting start.

    As for the Cardinal Archbish, I'll believe he understands quantum physics when he demonstrates exactly where in the chain of logic between observation and theory there's a deliberate move away from a designer. QM is pretty darn solid, and it works (take a look at Shor's Algorithm).

    Well, there's no argument from me against quantum physics - I used to work in the nuclear industry. But let's stick with the archbishop's article for now.

    I'm afraid I don't understand your comment above. To which observation and theory are you referring? How does the archbishop's alleged lack of understanding of quantum theory make any difference to the argument presented in his article? At present I fail to see the logic of your argument.

    I note that you use the word designer, but that is not a word associated with the ID world. Instead they talk about design as a phenomenon that can be emprically detected using the tools of mathematics and physics. Speculation about the identity of the designer (whether divine being, space alien, or metaphysical property of the universe) takes us beyond the realm of science at present.

    What observation? The observations made by experimental physics - stuff like the structure of the spectrum, discrete energy levels in photons and electrons, photoconductivity and so on - which have been the basic fuel for people like Newton, Einstein, Bohr and so on.

    What theory? Quentum theory, which is a very successful attempt to provide a mathematical foundation for the above observations. As part of that theory, the idea of the multiverse has been advanced. I can point you at very many fine online descriptions of how, for example, Einstein arrived at his conclusions from his observations, and the subsequent work in QM that has lead to our current state of understanding.


    As quantum theory is so non-intuitive, it has been the subject of intense and very sceptical analysis every step of the way. Despite - perhaps because of - this, quantum theory is the most exhaustively documented and tested physical theory ever, and one of the most spectacularly successful.

    The multiverse hypothesis is a natural part of this: although still controversial, it has a good claim to be a valid interpretation. Again, look at Shor's Algorithm - this is an amazing example of a practical computational use of quantum theory that relies on the simultaneous existence of multiple and classically exclusive states to produce hard results. It is a small step from this to the idea of multiverse.

    If the Cardinal Archbishop wishes to be taken seriously when he says that "scientific claims like neo-Darwinism and the multiverse hypothesis in cosmology [were] invented to avoid the overwhelming evidence for purpose and design found in modern science", then he is claiming a great error has been deliberately made. He assumes the burden of proof in making such an extraordinary claim. Where is that proof - or even, where might it be found? Ex cathedra has no place in science.


    I'm still very interested in your explanation of Dembski's exposition on why ID is not religious, which I quoted and tried to paraphrase earlier. I simply cannot see how his description of ID is any more scientific or less religious than our understanding of the Virgin Birth or the Resurrection. I would very much appreciate your insights on this, as it eludes me utterly.

    (* If you believe that design can exist independent of a designer - you have been careful to make that distinction - then I don't understand how you have a problem with design being a product of natural selection.

    Something worth noting. There can be no design without a designer, but there can be order without an orderer. (The classical Argument From Design infers design from the presence of order, which is not necessarily a valid inference, and concludes then that there was a designer.)

    Then design is a poor choice of word to describe the empirally detected phenomenon - outwith the ID community if you mention "design" then the natural thing to do is to think there must be a designer. Especially if you then go and add the word "intelligent" to the mix. Either the original proponents were incredibly naive in choosing to call their conjecture "Intelligent Design" as opposed to some phrase that doesn't carry strong implications about there being an intelligent designer (and in much of the US and other western nations that would be immediately understood as the Judeo-Christian God), or that's exactly the implication they wished to convey.

    I think that this is a case of the ID fraternity having their cake and eating it. One of Dembski's books is entitled: "Intelligent Design: A Bridge Between Science and Theology". Philip Johnson's "The Case Against Darwinism" is explicit in its objection to the 'atheistic' nature of Darwinism. Remine's biotic message theory argues that life was designed in such a way as to point to a creator God (and Remine was a regular on the Scientific Creationist circuit until he re-invented himself as an Intelligent Designer), The Discovery Institute (of which Remine is a fellow) support ID, in part, because they believe that evolution undermines Judeo-Christian morality, Alvin Plantinga argues that the existence of God is a "properly basic belief" and if Christoph, Cardinal Schonborn is uncertain as to whether the designer was God or Super-intelligent aliens, I'll eat his shiny red biretta.

    One could, of course, multiply examples. But I think it demonstrates admirably that rumours of studious agnosticism about the existence or nature of the deity among the ID fraternity is exaggerated.

    No. They do not talk about the designer directly, but to have design you must have a designer, and when you talk about intelligent design you must have an intelligent designer. That is the difference between ID and the ordering produced by Darwinian evolution.

    Almost every IDer I have ever heard has one specific candidate for the role of Designer - God. Simply because the ID world doesn't directly bring God into play doesn't mean that the existance of a designer is not a fundermental principle necessary for ID to be true.

As part of that theory, the idea of the multiverse has been advanced. I can point you at very many fine online descriptions of how, for example, Einstein arrived at his conclusions from his observations, and the subsequent work in QM that has lead to our current state of understanding.

    As quantum theory is so non-intuitive, it has been the subject of intense and very sceptical analysis every step of the way. Despite - perhaps because of - this, quantum theory is the most exhaustively documented and tested physical theory ever, and one of the most spectacularly successful.

    Thank you for the clarification. There’s no argument from me against fundamental physics and quantum theory. It provided me with a good living for over 20 years.

    The multiverse hypothesis is a natural part of this: although still controversial, it has a good claim to be a valid interpretation. Again, look at Shor's Algorithm - this is an amazing example of a practical computational use of quantum theory that relies on the simultaneous existence of multiple and classically exclusive states to produce hard results. It is a small step from this to the idea of multiverse.

    For those unfamiliar here is a simple introduction to the physics associated with the multiverse hypothesis. Scroll down the page to read further.

    I think you overstate your point substantially when you say that the multiverse hypothesis is a part of quantum theory. As far as I can see, the best that can be said for it is that it is a imaginative speculation made possible by one interpretation of quantum theory. It is clearly under active discussion at present, but it is far from universally agreed among cosmologists.

    You have mentioned Shor’s Algorithm twice now, but it is a theoretical formulation that depends on the presently theoretical concept of a quantum computer (as opposed to classical computers, such as exist at present). Since no one has yet succeeded in making a quantum computer, it remains a theoretical tour-de-force that awaits a practical embodiment.

    I do not think the ID fraternity can be blamed for basing their present scientific work on the current cosmological consensus. If and when the multiverse hypothesis is confirmed by further theoretical studies and practical observations, then that is a bridge the ID world will need to cross.

He assumes the burden of proof in making such an extraordinary claim. Where is that proof - or even, where might it be found? Ex cathedra has no place in science.

    And that dislike of “ex cathedra” is why the ID world are making their arguments on scientific and rational grounds. The only universe for which we have clear and irrefutable evidence is our own. Dembski’s formulation on the universal probability bound (10E-150) is based on what we know about our own universe based on observation and measurement.

    The archbishop’s article was not intended as an exhaustive review of the scientific issues and how they have been interpreted in RC pastoral and doctrinal teaching. He needs to develop his arguments more fully elsewhere. However, I would say the more fundamental burden of proof is on those proposing the multiverse hypothesis.

    In turn, it is statements like this that leave me scratching my head. The Virgin Birth and the Resurrection are theological positions intimately associated with certain religious texts and faith traditions (namely Christian). Without those texts and traditions we would know nothing about the Virgin Birth and the Resurrection. In Christian theology this is the whole concept of revelation and special grace.

    By contrast, the ID world (which is actually much bigger than Dembski, although he is the most well-known household name) are making their arguments on the basis of logic and reason from the established laws and facts of science. It is a position which can be embraced by those of all faiths and none. Do not be misled by those in the YEC world who have appropriated some of the ID terminology for their own use, wrongly in many cases.

    Rex Monday said:
    (* If you believe that design can exist independent of a designer - you have been careful to make that distinction - then I don't understand how you have a problem with design being a product of natural selection.

    With reference to the general point that Alan Cresswell has made about the use of terminology, the word natural is very slippery and requires careful definition to avoid misunderstanding. A large part of the argument here is just what constitutes “nature” in the first place, as opposed to working assumptions.

    The term “natural selection” is an oxymoron under a strict Darwinian paradigm – nothing does any active selection, for selection implies the ability to choose and for strict Darwinians the laws of physics and chemistry are not teleological, self-aware, and goal-directed, so there is no active choosing going on at all.

    “Selection” is therefore a complete misnomer and I would argue that it is being used in a very misleading way by Darwinists. In a sound-bite era the term is of course perfect, but a much more accurate description would be “differential reproductive success under the passive and non-teleological effects of environmental pressure” - food supplies, disease resistance, predators, weather etc.

    As it happens the ID world do not deny that “natural selection” is operating and is capable of effecting some evolutionary change. The most obvious example I can think of is those deep sea fish that once had (presumably) seeing eyes, but now have blind, non-seeing eyes. However, I note that this involves the loss of function and not the creation of function.

    Your phrase “design as a result of natural selection” begs the question as to the limits of the creative power inherent within a random mutation/natural selection paradigm. Dembski has attempted to define the limits of that power by strict mathematical arguments based on the flow of information from the environment into the genome, and Remine has dome likewise for the rate of that information flow, given what we know about sexual reproduction and the mathematics of population genetics.

    quote:
    Rex Monday said:
    How might you distinguish between the acts of an unknown and unknowable designer, and the workings of purely natural laws?)

    That is an extremely pertinent question. This is where the specialist terminology of the ID world (or at least the better known parts of it) comes in, such as the universal probability bound, explanatory filter, specified complex information, and irreducible complexity. These are all scientific concepts which are defined with precision in the writing of Dembski, Behe and others.

    The arguments supporting these scientific concepts are made on purely rational and logical grounds that are fully consistent with the known laws of science and facts of the universe. There have of course been many attempts to rebut these concepts, but none that have convinced me. I recommend studying them for yourself since the Internet is full of misunderstanding and misinformation on these points.

    The “working of purely natural laws” is also a question begging phrase, given what I said earlier about the slipperiness of the word natural. Since the ID world is sympathetic to a natural teleology (whether implicit or explicit), there are those who would not explicitly associate themselves with Dembski and Co. (for whatever reason), but who have nevertheless broken away comprehensively from a strict Darwinian approach and are now part of the wider ID fraternity.

    This post has taken a lot of energy. If I don’t post in depth any more for today, nobody please take it personally.

    Our cell membranes are described as "selectively permeable," but this does not mean that they actively choose anything, but rather that their structure allows some things to pass through them but not others. The term "selection" does not imply intelligence.

    The term is one of Darwins own choosing. "Natural" is in contrast to "artificial" (the analogy being with the artificial selection of certain traits in animals by human breeders to produce distinct new breeds; in the wild analogous selection happens, except in the wild the selection criteria is simply reproductive success and there is no breeder artificially selecting any trait).

    Now to deal with some of Callan’s points:

    quote:
    The three theses you cite sum up Rex's point admirably. Davison postulates that the evolutionary development of a species is somehow pre-ordained rather than determined by natural selection, an idea which can be simply dismissed by the two words "mass extinction"
    If you were more familiar with Davison’s ideas, you would find that the phenomenon of extinctions is one of the fundamental facts on which he bases his work. In his model, life-forms evolve through non-sexual reproduction and non-Darwinian means. Once sexual reproduction begins, it renders the life-form vulnerable to genetic deterioration and subsequent extinction.

    He sees evolution driven by the decompression of existing information within the life-form. As an analogy to aid understanding of what he means by this, consider those compressed but self-extracting files that one downloads over the Internet. He sees something similar in life-form information. For him evolution proceeds by distinct jumps, “saltation”, which has a long history in opposition to Darwinian ideas.

    quote:
    Callan said:
    Remine's thesis is the subject of a laudatory review in Answers in Genesis.

    If you had spent a little more time on the AIG site you would have found the following disclaimer in relation to Remine’s book The Biotic Message:
    quote:
    Although the book advocates a creationist position, it is not a biblically-based creationist position. For example, the ‘sequential release’ explanation of the fossil record (p. 423) cannot be made to fit the scriptural account. Although a direct discussion of the age of things is avoided, the explanation of the fossil record (and apparent acceptance of the big bang) seems to assume long ages, thus precluding the biblical time-frame of only thousands of years.
    Remine is no young earth creationist and no supporter of the specific approach of Answers in Genesis. Just because AIG sells his book doesn’t make it otherwise. No doubt AIG also approves of motherhood and apple pie. Your argument here is lamentably weak and no more than guilt by association.

    You will find that Remine subscribes to an old earth paradigm and his arguments are developed on scientific and mathematical grounds, particularly with respect to population genetics. He has defended his thesis in depth at the ARN forums. If anyone can rebut it competently he wants to hear from you.

    quote:
    Callan said:
    The final thesis, EAM appears to be nothing more than warmed over Lamarckism, a theory that has been consigned to the rubbish heap long ago.

    Here’s what EAM is:
    quote:
    EAM asserts that vital, (as opposed to trivial), novelty in organisms, begins exactly where and when environmental pressure forces it to happen, provided that that environmental pressure is both destructive and chronic, (without being entirely lethal), or, that it offers a highly advantageous opportunity to the organism. Adaptation is either the organism restructuring itself, and/or its offspring, so as to cope with a novel negative environmental pressure, or, so as to thrive by taking better advantage of a novel environmental opportunity.
    Dismissal as “warmed over Lamarkianism” is a lamentably weak argument and simply guilt by association again. EAM ideas postulate that genetic mutations are not random with respect to environmental selection pressure. In other words, the life-form shows some awareness of its own evolutionary needs. As the ISCID article goes on to say:

    quote:
    EAM is a process that involves non-mechanical, non-physical, phenomena, such as self-awareness, cellular intelligence, memory, intention, and other aspects of 'mind'.
    Please also note this comment from the ISCID article:

    quote:
    EAM is the 'multiple designers' version of Intelligent Design. It holds that every organism possesses intelligence to some degree, and that it uses that intelligence in an unconscious, instinctive way, to redesign itself and/or its behaviour, and that of its offspring, in the face of novel, crucial environmental demands.
    This of course flies in the face of strict Darwinism. However, once one allows for the concept of a natural teleology, it permits some very fruitful lines of enquiry to proceed. You will find that EAM ideas are grounded in scientific observation and have recently received a boost from a paper reporting some distinctly unexpected results on the variability of mutation rates under selection pressure:

    quote:
    ”The new data show that if more mutations show up at a gene, that gene tends to accept a higher percentage of those mutations.”
    That is not a result that anyone was expecting, nor can it be claimed as a prior prediction of neo-Darwinian theory. It may, however, be compatible with EAM ideas.

    Callan said:

    Ahem, Callan, you’ll find that Remine published his book The Biotic Message in 1993, long before “Intelligent Design” became the well-known name for a school of thought in opposition to strict Darwinism. Remine certainly does take part in open public debates with prominent Darwinists, but his arguments are rational and rooted in mathematical logic, scientific laws and known facts.

    I can find no evidence that Remine is a present fellow of the Discovery Institute. Please document this point. However, as I used to work in the nuclear industry, it is no surprise to me that many scientific ideas have important social and political ramifications. It is naïve to think that scientific ideas can be promulgated in a political vacuum or that they automatically have no moral implications. Is nuclear power safe?

    It is no secret that some of the better known names in the ID fraternity are theists of one form or another, but others are openly agnostic and a few eschew any form of theism. As the Archbishop’s article shows, ID ideas can certainly be interpreted in a form that is compatible with an orthodox Christian theology. However, it is important to distinguish between the prior scientific ideas and the way those ideas are received in various faith communities.

    My point about Mass extinction was in response to this sort of argument, from the link already posted.

    quote:
    I propose that these internal factors may prove to be the primary if not the sole causes of organic evolution. In short, I suggest that evolution has been largely an emergent process in which the environment may have played, at best, a trivial role.
    So not only is the current morphology of a given species encrypted on its DNA but any future evolutionary variations are lurking in there as well - a thesis that appears not to have found any vindication from the vast amount of research into DNA since Watson and Crick. This is the sort of thing which is the staple of dodgy science fiction, such as the Blake's 7 episode, Terminal which hinged on humanity being doomed to evolve into a species of homicidal primates. Clearly this sort of evolutionary determinism is incorrect as it overlooks the fundamental role played by the environment on a given species.

    But also the environmental factors which a species encounters are 'trivial' in its development. This ignores, for example, the opportunity seized by the mammals after the mass extinction of the Cretaceous which eliminated the Dinosaurs. Clearly an event of this magnitude can hardly be considered trivial. Nor, for example, can climate changes which are complict in other mass extinctions such as the changes at the end of the Eocene era. Clearly environmental factors had a role to play in the development of species which was far from trivial. If Davison is correct then the predetermined evolutionary pattern of a species' development may actually mitigate against its survival as its transformation from one form to another may occur at a time when such a transformation is not evolutionary advantageous to it.

    What of it? The review I linked to stated that Remine was deeply parteigenossen as far as his espousal of Big Bang theory was concerned. But whilst I don't consider AiG to be a reputable scientific site I do consider them to have a reasonable grasp of what constitutes creationist literature. If something is sufficiently far away from the scientific mainstream to warrant the approval of AiG it constitutes rather more than motherhood and apple pie. It demonstrates that ID and creationism have more in common with one another than either does with science.

    But your first definition could have been lifted from Shaw's Back to Methuselah. The idea that organisms choose to evolve in a certain direction which are advantageous to them is *precisely* what Lamarckism is. If on the other hand organisms merely react to selective pressures created by their environment EAM is merely Darwinism but you're not arguing that are you?

    quote:

    Nope, thought not. That is, AFAICS, what Lamarck argued. Where would you say that EAM differs from Lamarckism?

    Incidentally, of course you noted that EAM is driven by changes in the environment whereas Davison alleges that such changes are trivial and Remine alleges that life was set up by divine design. The three explanations are not only flawed but incompatible with one another.

    quote:
    You will find that EAM ideas are grounded in scientific observation and have recently received a boost from a paper reporting some distinctly unexpected results on the variability of mutation rates under selection pressure
    I would hesitate before suggesting that the genes cited in the article willed their mutational variation on the basis of your link. There is no evidence of any mechanism by which this could happen. Incidentally, Lahn appears not to have recanted his comments that there is no evidence for ID and that it is not a scientific theory. This experiment may cause neo-Darwinian theory to be revised but there is no evidence that it will cause it to be abandoned.

    The fact that Remine's work pre-dates ID confirms, I would have thought, my contention that he is a creationist who moved under the ID banner for tactical reasons. The fact that he debates with Darwinians is no guarantee of scientific rectitude - so does Duane Gish and plenty of others. You are quite right that he is not a current fellow of the Discovery Institute. Mea Maxima Culpa. However googling "Walter Remine discovery institute" points to a bio provided for an online debate where he is cited as a fellow and a number of internet discussions where he puts "Fellow of the Discovery Institute" in his sig. See here and here

    It is not a sufficient argument but it cannot be ruled out of court. If a Doctor tells you that he believes that smoking is not harmful and he is in the pay of Mr Benson and Hedges one should regard his arguments with suspicion. I think a simple test is to ask yourself how much of the Blind Watchmaker would Dawkins have to re-write if he found God. A lot of the rhetoric would have to go but the essential science would be sound enough. Similarly there is nothing (apart from academic snarkiness) that would preclude Dawkins from publishing a paper jointly with Kenneth Miller, despite their theological divergences. On the other hand if Remine stops believing in God he may as well get his publishers to pulp the Biotic Message. This demonstrates the ID agenda, admirably. It is an essentially ideological enterprise which sees Darwinism as the basis of materialism and therefore sets out to replace it with another paradigm. The ideological commitment precedes the science inasmuch as the Discovery Institute can, apparently, tell with accuracy and without doing any research that within twenty years they will have replaced Darwinism as the dominant paradigm. Whilst I disagree profoundly with the philosophical arguments one finds in Dawkins' work to compare him to Dembski et. al. is rather unfair.

    If his claim is to be taken seriously, he must show some evidence of it. ID supporters who use this op-ed piece of his to back up their arguments are clearly not in it for the sober scientific case he makes, for he makes none!

    Dembski's probability studies are not impressive. There is no particular reason to believe his model reflects reality, and they are well refuted elsewhere.

When a new species has better attributes for survival than others and thus prospers where others do not, selection seems a good word to use - and natural seems a good description of the forces at work.

    quote:


    “Selection” is therefore a complete misnomer and I would argue that it is being used in a very misleading way by Darwinists. In a sound-bite era the term is of course perfect, but a much more accurate description would be “differential reproductive success under the passive and non-teleological effects of environmental pressure” - food supplies, disease resistance, predators, weather etc.


    That seems an excessively circuitous way of saying 'natural selection'! Natural selection remains a perfectly good, clear and unambiguous phrase. Where is it being misused?

    quote:


    As it happens the ID world do not deny that “natural selection” is operating and is capable of effecting some evolutionary change. The most obvious example I can think of is those deep sea fish that once had (presumably) seeing eyes, but now have blind, non-seeing eyes. However, I note that this involves the loss of function and not the creation of function.


    This shibboleth of ID - and creationism - is hard to understand. If no new function can be created through mutation, why do we see it happen all the time? Why would beneficial mutations not occur?How come genetics is labouring under such a huge burden of error, while producing such good results?

    quote:


    Your phrase “design as a result of natural selection” begs the question as to the limits of the creative power inherent within a random mutation/natural selection paradigm. Dembski has attempted to define the limits of that power by strict mathematical arguments based on the flow of information from the environment into the genome, and Remine has dome likewise for the rate of that information flow, given what we know about sexual reproduction and the mathematics of population genetics.


    Those models have been heavily and I believe successfully criticised for fundamental inappropriateness (not to mention, in Dembski's case, actual mistakes in the maths). It's like those mythical equations that purported to show that a bumblebee could not fly.

    Taking known mutation rates - which can be observed - straightforward maths shows that the rate of change in organisms can easily be accounted for by what we see. An alternative model that appears very flawed and seeks to deny observations is not compelling.

    That is an extremely pertinent question. This is where the specialist terminology of the ID world (or at least the better known parts of it) comes in, such as the universal probability bound, explanatory filter, specified complex information, and irreducible complexity. These are all scientific concepts which are defined with precision in the writing of Dembski, Behe and others.

    The arguments supporting these scientific concepts are made on purely rational and logical grounds that are fully consistent with the known laws of science and facts of the universe. There have of course been many attempts to rebut these concepts, but none that have convinced me. I recommend studying them for yourself since the Internet is full of misunderstanding and misinformation on these points.


    Well, there we'll have to differ, as I find the critiques of ID's claim to science entirely convincing, for any number of reasons - not least that no _workable_ definitions of the things you list have been created. Where definitions have been worked up to a point where they can be tested, they prove useless - if you follow the history of Behe's ideas in particular, you can see this process in action.


    quote:


    The “working of purely natural laws” is also a question begging phrase, given what I said earlier about the slipperiness of the word natural.


    Is that slipperiness the reason why Dembski's article to which you referred so difficult to fathom? I'm at the disadvantage of not finding the word slippery at all, and the distinction between natural and supernatural simple to appreciate - with ID and its talk of minds acting on physical laws falling firmly on the supernatural side.

    quote:


    Since the ID world is sympathetic to a natural teleology (whether implicit or explicit), there are those who would not explicitly associate themselves with Dembski and Co. (for whatever reason), but who have nevertheless broken away comprehensively from a strict Darwinian approach and are now part of the wider ID fraternity.

    One of the strongest advocates of teaching alternatives to evolution is the Discovery Institute in Seattle, which promotes the idea, termed intelligent design, that the variety and complexity of life on earth cannot be explained except through the intervention of a designer of some sort.

    Mark Ryland, a vice president of the institute, said in an interview that he had urged the cardinal to write the essay. Both Mr. Ryland and Cardinal Schönborn said that an essay in May in The Times about the compatibility of religion and evolutionary theory by Lawrence M. Krauss, a physicist at Case Western Reserve University in Cleveland, suggested to them that it was time to clarify the church's position on evolution.

    The cardinal's essay was submitted to The Times by a Virginia public relations firm, Creative Response Concepts, which also represents the Discovery Institute

    There is some discussion in other places that the original op-ed piece was part of the politics of some internal Vatican wrangling, and can be construed as a tentative bit of walking the biscuit to see who nibbles.

    Where would you say that EAM differs from Lamarckism?

    Lamarckianism talks loosely about the inheritance of acquired characteristics as the mechanism for evolutionary change. It was a scientific theory formulated in an era long before the science of genetics became established. So, just like Lipton’s Iced Tea, don’t knock it till you’ve tried it – Darwin accepted Lamarckianism to some degree:

    quote:
    From Darwin’s Origin of Species, chapter 5:
    From the facts alluded to in the first chapter, I think there can be little doubt that use in our domestic animals strengthens and enlarges certain parts, and disuse diminishes them; and that such modifications are inherited. Under free nature, we can have no standard of comparison, by which to judge of the effects of long-continued use or disuse, for we know not the parent-forms; but many animals have structures which can be explained by the effects of disuse.

    Overall I think you have completely missed the fundamental scientific issue at stake that has enabled EAM ideas to become popular in some circles. Are genetic mutations always and in every place random with respect to environmental pressure? Random in this context means completely uncorrelated with no deterministic or statistical relation whatsoever to the environmental pressure.

    That is what strict Darwinism has held up to now. It at least has the merits that it is a testable scientific prediction, especially now that the technology is available to examine and monitor genetic mutations in full detail. It only takes one confirmed case of non-randomness to show that Darwinism is not the full story.

    quote:
    Callan said:
    Incidentally, of course you noted that EAM is driven by changes in the environment whereas Davison alleges that such changes are trivial and Remine alleges that life was set up by divine design. The three explanations are not only flawed but incompatible with one another.

    Your comment here also illustrates my point perfectly (apart from your misrepresentation of Remine). There is no one single ID theory, but a broad field in which a variety of non-Darwinian scientific approaches jostle side-by-side for acceptance strictly on their scientific merits. Some ideas are uncomfortable bed-fellows and some ideas are completely incompatible with others, but that is only to be expected in an open scientific debate on unresolved questions.

    Lamarkism depends on those "acquired characteristics" being developed through the life time of the organism, rather than being inherited directly from the parents. So, a characteristic such as the muscles of a blacksmith are acquired during the life of the blacksmith through the physical exertion of those muscles in his work. In Lamarkism the children of a blacksmith should have well developed muscles, because their father has well developed muscles. It is totally incompatible with genetic inheritance - unless one can show that punding metal all day changes ones genes to favour bigger muscles in those who inherit those genes. Even though Darwin acknowledged Lamarkism as an influence, it was the flaws in Lamarkism (ie: that, actually, it didn't explain inheritance as actually observed) that led him to a different form of inheritance.

    Interestingly, there could be a case for a Lamarkian type of inheritance in human cultures. Cultural traits that are used are selectively transmitted to later cultures, those that aren't are less likely to be transmitted. But then, apart from a few advocates of memetics, no one considers there to be a genetic analogy in culture.

    I would strongly dispute the underlying concept in the Cardinal's essay that science is specifically concerned to "explain away" evidence for design. It is not. Rather, it seeks to construct models that accurately describe observed reality. This is not the same thing. Faced with a remarkable phenomenon such as the vertebrate blood clotting cascade, which certainly is a case in point, there are two paths: too say "Oh, this must be design by God supernaturally placed in the world", or "Fascinating. How did that come about?". Only the latter of these paths is a path of scientific enquiry.

    But finding a non-supernatural model of the origins of the blood clotting cascade (as has been done) does not say whether a supernatural God designed it or not. It merely says how, if God exists and did design it, He put it into action. About whether God does exist, and did so, science is silent. The idea that any scientific model is saying that God didn't design it, or even worse that God doesn't exist, is a pernicious misunderstanding which unfortunately the Cardinal seems to have picked up on.

    Fundamentally, the question of design by God is a philosophical one, not a scientific one, and it is a category error to try to introduce the question into science, which makes the subject of its enquiry nature, not supernature.

    The Cardinal would do well to listen to Ken Miller. Yes, from a scientific frame of reference evolution is unplanned and unguided. But it's a pretty poor sort of God that finds the unplanned and unguided impossible to fit into His providence.

    Actually my points were:


    There seems to be a degree of performative inconsistency in complaining about ad hominems whilst ignoring the substantive argument.

    quote:

    Actually no Darwinian would argue that the environment never has an effect on mutations. UV radiation, for example, can act as a mutagen. So mutations are not random with respect to the environment inasmuch as the environment dictates the level of mutagenic pressure to which an organism is exposed. EAM is clearly based on a misunderstanding.

Some ideas are uncomfortable bed-fellows and some ideas are completely incompatible with others, but that is only to be expected in an open scientific debate on unresolved questions.
    Firstly I summed up Remine's thesis quite adequately. According to his own website the books thesis is:

    quote:
    The central claims of the theory are simple and plausible: Life was reasonably designed for survival, and to convey a message that tells where life came from. The message can be described in two parts:

    1. Life was designed to look like the product of a single designer.
    2. Life was designed to resist all other explanations.

    In other words, evolutionary theory helped shape the pattern of life — with a reverse impact. Life was intricately designed to resist all evolutionary explanations, not just Darwin's or Lamarck's.

    Secondly, it appears to be the contention of ID theorists that a highly successful scientific theory should be abandoned in favour of a ragbag of doubtful theories on the ground that a designer or designers, any designer or designers, are preferable to a theory that admits of the possibility that there may have been no designer after all. The ID tent contains Old Earth Creationists, Young Earth Creationists, People like Behe who believe that Goddunit but are prepared to accept that some evolution took place, EAM Lamarckians and Anthony Flew. The point of unity is a prior ideological commitment to the wrongness of Darwinism. Logically most ID theories must be wrong, as only one of them can be right. That one of them is right strikes me as being unduly optimistic.

    Style over substance is the perfect description of ID. What ID, in effect, is asking us to do is to sack a perfectly decent and competent plumber and replace him with a member of the new plumbers guild. These guild members have entirely different and incompatible explanations as to what is wrong with ones drains but they are united in the belief that Mr Competent is terribly immoral. You'll pardon me if I stick with Mr Competent.

    I write this first bit before I read the last 3 days worth of postings on the thread, because I've been off reading over the weekend & want to get my thoughts down. So if it is completely irrelevant and off-topic, aplologies.

    quote:

    That is an extremely pertinent question.

These are all scientific concepts which are defined with precision in the writing of Dembski, Behe and others.

    The arguments supporting these scientific concepts are made on purely rational and logical grounds that are fully consistent with the known laws of science and facts of the universe. There have of course been many attempts to rebut these concepts, but none that have convinced me. I recommend studying them for yourself since the Internet is full of misunderstanding and misinformation on these points.

    OK, so I looked around for Dembski and Behe and others and found some online essays which I read to try to refresh my ideas of what they are talking about.

    One which seemed to address all those points you mention, and to be relatively recent is [URL=http://www.iscid.org/papers/Dembski_ IrreducibleComplexityRevisited_011404.pd]Irreducible Complexity Revisited[/URL] by William Dembski (November 2004) available on the iscid.org website.

    I spent a lot of time reading it (& a few other things) over the weekend and made some notes on it. I'm afraid the notes get angrier as I go on because it seemed to me that the notions you mention are not "defined with precision", or not in this paper, which appeared to be evasive and polemical.

    There's no point in going through in any detail, but three or four main things stand out:

    First, the whole notion of an "irreducible core" seems far from proved. I'm not at all sure that5 such things exist in quite the way they are described; and if they do I'm not at all sure that the "fundamental molecular machinery" of life contains many, if any, examples of them. OK, I would have said that before I read this paper, but these feelings are strongly reinforced by the paper which fails to convince. It also doesn;t help that he claims various structures, such as flagellae, as "irreducibly complex" with no backup to the claim. Its just an assertion. A "gosh wow, I can't believe it!".

    Second - and this one is a minor point - he uses the example of a city as an illustration of what he calls "cumulative complexity" which he tries to distinguish from "irreducible complexity, asserting that even if it is possible for a "cumulatively complex" structure to come about through natural selection, it is impossible for an irreducibly complex one:

    quote:

    It is possible to successively remove people and services from a city until one is down to a tiny village - all without losing the sense of community which in this case constitutes the city's basic function.

    But this is nonsense. If a "sense of community" was the basic function of a city then we'd all get more or it by living in tiny villages. Or big houses in the country, or caves, or nests. Cities are actually very good analogies for the molecular machinery of cells, because they function by bringing people (and other things) face to face with each other, making new kinds of economic activty possible. And also by compartmentalising econmic activities away from each other. Just as a cell functions by bringing various objects into contact over surfaces and creating compartments for things to happen in.

    Cities do not typically grow by infinitesimally gradual continual stages, they grow in bursts. And there are step changes in function with growth - when the density of people goes above a threshold then new kinds of economic interaction that were not possible before now become possible. New kinds of supply emerge to satisfy new kinds of demand. Quanititative change becomes qualitative change. World metropolises like London or New York are not just larger versions of smaller world city, a Cape Town or Glasgow or Baltimore. Which are themselves not just larger versions of national-scale city. And so on down to the village.

    Much the same thing seems to have happened in the development of living cells. At certain scales, quantitative becomes qualitiative. New forms became possible - maybe quite suddenly on an evolutionary scale. The history of life is in many ways the history of compartmentalisation and modularisation within and between cells. This is one mechanism that allows exactly the sort of thing Dembski doesn't believe in to happen - appearance of a crude version of a new thing.


    Thirdly - and this is much more important - he repeatedly demands a "seamless Darwinian account that is both detailed and testable..." without ever saying what such a testable account would be. He presumably knows perfectly well that we can't go back in a time machine and see the real ancestry of current living things. So what is his test? In one place he dismisses "just so stories", scenarios made up to describe what things might have been like, while in another demanding that biologists make up just such stories - and somehow prove them

    The only statistically testable models of the actual course of evolution are phylogenetic ones - we have the endpoints, the twigs of the tree, and we can build models of the brranches and the trunk that relate them together. But he seems to show no awareness of that. (& if he did he would I suppose quite correctly point out that such models assume kinship between extant forms so can never "prove" it)

    What would he accept as evidence?

    Fourthly, he writes:

    quote:

    By definition natural selection selects for existing function - in other words a function that is already in place and helping the organism in some way. On the other hand natural selection cannot select for future function - functions that are not present and in some way currently helping the organism are invisible to natural selection. Once a novel function comes to exist the Darwinian mechanism cann select for it. But making the transition from old to new function is not a task to which the Darwinian mechanism is suited.

    What he's done here is to define away the possibility of the core of the argument for the orgin of species by means of natural selection. He's begged the question utterly. And he is ignoring - or rather ruling out of court - the possibiity of anything new emerging which can from then on be subject to selection. Ignoring not only the possibility fo the kind of qualititive step change I mentioned before, but any sort of emergent property and - much more importantly to the theory of ecology - ignoring the possibility of preadaptation, that is some character of an organism that was previously useless or even deleterious being advantageous in different circumstances.

    He then goes off on one about concepts such as "scaffolding" and so on in a way which I think shows he doesn't quite understand the points being made.

    Enough. The rest is less impressive than the first part because its built on the first part so can't convince the not already convinced. Though he makes a couple of glaring errors I think. One is perhaps just a matter of style. It is not always clear when he is taking about evolutionary time, ecological/population time, lifecycle time or phsysiological timescales. That's really important if anyone is goiung to make sense of his rather baroque structure of supposed probabilities he's calqued on Drake's equation.

    The other more subtle but maybe more informative error is the way he keeps on talking about "the bacterial flagellum" and similar phrases, as if there is only one bacterium, only one flagellum. But of course there are millions of them, all slightly different. The idea that a flagellum is "irreducibly complex" and cannot evolve would be intuitively easier to swallow if it were not that case that there are vast variations on them in life. The same goes for much of the molecular machinery of life. Most organisms lack some part of some of the fundamental metabolic pathways for instance. But bits are all they need to live as they live.


    Whoops, theres another fallacy. A statistical fallacy kin to the one that's getting Professor whatsisname kicked out of the BMA for giving bad expert evidence on cot deaths. Well illustrated by Dembski's own story about going round a supermarket blindfold and picking out exactly the right ingredients to bake a cake. That's the golfball and blade of grass fallacy. Evolution doesn't need to pick out the right ingredients to bake "the" cake, but only "a" cake. Or for that matter a pie or a pizza or porridge or any one of a number of dishes known or unknown. It only has to do well enough.

Once sexual reproduction begins, it renders the life-form vulnerable to genetic deterioration and subsequent extinction.

    He sees evolution driven by the decompression of existing information within the life-form. As an analogy to aid understanding of what he means by this, consider those compressed but self-extracting files that one downloads over the Internet. He sees something similar in life-form information.

    That's actually very similar to what Lamarck thought (though not to what his opponents said he thought). He reckoned that variation was inherent in living things and was expressed in different ways in different environments. And that each living thing was on one of a small numbers of evolutionary tracks leading up to a limited number of higher forms (like ourselves, daisies & starfish)

    So evolution was driven by inner forces - an "onwards and upwards" tendency to higher things - interacting with a changeable environment.

    The word "evolution" meaning literally something like "unfolding" was not until towards the end of the 19th century confined to what we now use it to mean. It had a range of meanings overlapping with "development".

    The idea of inheritance of accquired characters wasn't particularly something Lamarck pushed more than than anyone else. Darwin also thugh there might be something in it. It wasn't really until Fisher and the other population biologists came on the scene in the early 20th century that it became apparent that Mendelian inheritance made such things unneccessary.

    If there is someone the ID people are really arguing against it isn't Darwin, its Fisher. Who unlike Darwin, could do hard sums.

    And would have seen why

    quote:

    is either meaningless or wrong. To tell which we'd have to agree on what "vulnerable to genetic deterioration" meant.

    The misunderstanding here is yours. No one has ever claimed that some environmental affects (such as EM radiation) cannot cause genetic mutations. The key issue is what kind of mutation and at what location on the gene.

    Darwinists say that the nature and location of the mutation will be random with respect to the environment. EAM says it ain't necessarily so.

    My understanding is that there will be some areas of the genome which, due to location on the chromosome or other factors explicable by conventional science, that are more prone to mutation. And, that different causes of mutation (radiation, chemicals) will affect different areas of the genome differently. Though that's all dependant on the precise structure of the genome rather than the environment per se.

    Of course, the effect of any of those mutations on evolution is anything but random. Genes that have little survival benefit many mutations can (relatively) safely build up through subsequent generations. Mutations in other genes would not be transmitted to subsequent generations because of severe delitarious effects. That's Darwinian evolution, fitness of genetic variation to particular environments.

    What I don't understand is what mechanism could result in the environment having any other effect on genetic mutation. How does the environment affect which areas of the genome are susceptable to mutation?

    Do they?

    And there I was thinking that certain mutagens promote methylation of a cytosine DNA residue next to a guanosine into 5-methylcytosine, which DNA repair is likely to alter into a thymine, so that a DNA sequence ...XCGX... preferentially mutates into ...XTGX... which a 1/2 chance of the now mismatched G on the opposite strand being converted into adenosine.

    So these mutagens tend to convert CG dinucleotides into TG pairs, but GC into AC (IIRC)

    Which, as well as being one of the many possible influences on the skewed ratio of G+C to A+T seen in many species, will also tend to convert, for example, sequences coding for the amino-acid alanine into ones that code for threonine, or possibly glutamic acid or valine...

    ... and so on. Lots of mutations have specific causes and many are more probably in some circumstances than others.

    Also the mutation rate is itself subject to selection and varies not only between organisms but between parts of one geneome. Also the repair mechanisms work differently in different circumstances. And some parts of some genes are even "deliberatly" edited by enzymes. As are most mRNAs & many proteins which of course has similar effects - transcription and translation mechanisms are part of the inheritance of an organism.

    All behaving differently in different circumstances and therefore subject to modification over evolutionary time by natural selection.

    Up to now, I have been following your arguments about the science of this with interest and respect. However, your airy and dismissive parallel between the Wedge Strategy and the Homosexual Agenda, your plumbing analogy, and your characterisation of the Wedge Strategy as public relations has cost you some of that respect.

    The Wedge Strategy document is devastating evidence of the motivations and aims of the new "plumbers". It cannot be dismissed so cavalierly as you do. Why should ID proponents need a PR strategy anyway? If the science is good enough, replicable enough, testable enough, subject enough to falsifiable tests, it will stand. If not, it wont. If the science is good, the fact that that some of it may run contrary to received understanding will simply affect timescales, the degree of scrutiny and the pace of general acceptability. Good ideas, good findings, will eventually become part of the overall understanding. There is no need to be paranoid about acceptability.

    I was under the impression that was the common definition.

    Rex Monday, I’m not interested in discussing or defending the Wedge Strategy document or the Discovery Institute per se, but I will respond further in due course on the scientific issues. That is where the focus of my interest lies.

    Neil

    I was not talking about the Wedge Strategy (and I quite understand why you wouldn't want to either!) nor was I talking about the Discovery Institute. As I have tried to make perfectly plain to the point of (and I fear beyond) boring repetition, I am unable to understand your interpretation of the Dembski piece you quoted earlier - viz

    quote:

    Dembski's article about ID in the Oxford Handbook of Religion and Science makes his own position crystal clear

    In particular, as I said before, I have problems with the conclusion:

    quote:

    It follows that the charge of supernaturalism against intelligent design cannot be sustained. Indeed, to say that rejecting naturalism entails accepting supernaturalism holds only if nature is defined as a closed system of material entities ruled by unbroken laws of material interaction. But this definition of nature begs the question. Nature is what nature is and not what we define it to be. To see this, consider the following riddle: How many legs does a dog have if one calls a tail a leg? The correct answer is four. Calling one thing another thing doesn’t make it something else.

    Likewise, defining nature as a closed system of material entities operating by fixed laws of interaction doesn’t make it so. Nature is what nature is, and prescribing methodological materialism as a normative principle for science does nothing to change that. ID theorists argue that methodological materialism fundamentally distorts our understanding of nature. In assessing the validity of ID, the crucial thing is not whether they are right but whether they might be right. Given that they might be right, methodological materialism cannot be taken as a defining feature of science, much less should it be held dogmatically. To make methodological materialism a defining feature of science commits the premodern sin of forcing nature into a priori categories rather than allowing nature to speak for itself.

    To sum up, methodological materialism presents us with a false dilemma: either science must be limited to “natural explanations” (taken in a highly tendentious sense) or it must embrace “supernatural explanations,” by which is meant magic. But there is a third possibility:neither materialism nor magic but mind. ID theorists are not willing to concede the materialist claim that a designing intelligence (mind) interacting with matter is “supernatural.” Indeed, investigations by ID theorists are beginning to demonstrate that this interaction is perfectly natural — that nature cannot be properly understood apart from the activity of a designing intelligence.

    To me, installing a 'designing intelligence' that acts outwith 'a closed system of material entities operating by fixed laws of interaction' is a theological statement, which as I have so tediously restated seems to me to be more at home describing miracles than science. I can't see how Dembski's extension of science to cover the apparently supernatural would work, especially if it means abandoning the fixed laws of interaction. How does that differ from theology? How *is* it science? What rules would it work by? Dembski does not say - or if he does, I am unable to discern where he says it. Merely calling one thing another thing doesn't make it that thing, after all...

    You state that it is 'crystal clear' that Dembski is describing science, rather than theology. All I ask is that you share some of that clarity, even if just by paraphrasing what Dembski says above in a way that shows the error of my reasoning.

    If you do not wish to do this, then I am happy to abandon this line of enquiry. You merely have to say.

    I think that you are being very over-optimistic and somewhat naive about what is involved in the world of science and technology, especially the science of biological origins. In the USA this area of science has become extremely politicised with careers on the line and libel cases in court.

    I used to work in the nuclear industry. They had an enormous PR department to sell their ideas to the public. The fundamental science involved was not the issue, but rather it was the social and political ramifications. Do you think nuclear power is safe?

    I'm with Karl on this. I am perfectly happy with the commonly understood definitions of those phrases - and while you might be disappointed with this, it really is up to you to show why these are wrong.

    If you can show how Dembski's apparent conflation of the supernatural with the natural is scientific rather than theological, I will be most interested. As I said I have read Dembski without enlightenment, let alone crystal clarity, and if this is the fault of my orthodox views then I am unlikely to achieve a breakthrough under my own steam.

    You're there already. Over to you!

    The PR in the nuclear industry relates to the technological applications of the findings, not to the pure research findings themselves. The theoretical bases and some of the publications of research results were controlled, during later stages, for security reasons, once the technological implications opened up. I see no parallel between that argument and the academic research issues embraced by ID ideas.

    I will treat your assertion of over-optimism and naivety to refer to my ideas, not my character. In the same spirit, I find the ideas in your last post to be confused and confusing. I am not a practising scientist, but I know a logical flaw when I see it. But given that this is a tangent to the main debate, I'll leave the debating floor and enjoy the detailed exchanges (from which I'm learning quite a lot).

    My comments were made to the contents of your post and not to you personally.

    I cannot see the logical flaw in my post that you do. What is the ‘safe’ dose of radiation to the human body? What is the ‘safe’ level of plutonium that can be ingested in the human body without ‘harmful’ effects? With present technology what are the statistical ‘failure’ rates for nuclear plant and equipment?

    Are these scientific questions? Or are they merely social and political?

    And do you think that someone might ever have a vested interest in obscuring these questions or even precluding public discussion of them?


    Karl Liberal-Backslider;

    As for the phrase “scientific frame of reference”, Googling the phrase brought up this absolute gem (from here, with my emphasis):

    quote:
    In fact, with the rise of modern science alchemy split into two branches--modern chemistry and mystical psychology. Jung brings mystical psychology into the 20th century by constructing a scientific frame of reference for it. It is this framework that supports research into psychic phenomena.
    So there is at least one person who thinks that “scientific frame of reference” applies to mystical psychology. I think this demonstrates that the phrase is ab initio so vague that in any particular context it requires careful definition before it confuses more than it elucidates.

    I submit that at the moment Karl’s phrase ‘scientific frame of reference’ is almost meaningless. This phrase simply throws the discussion back one stage as to what ‘science’ and ‘scientific’ mean.

    This is not a semantic game, but rather it goes to the heart of why the ID community think (with integrity) that they are doing science and others (with equal integrity) think that they are not. We are not speaking the same language and therefore talking across one another.


    Rex Monday:

    Here is what dictionary.com gave me on the meaning of supernatural:

    quote:
    America Heritage definitions:
    1. Of or relating to existence outside the natural world.
    2. Attributed to a power that seems to violate or go beyond natural forces.
    3. Of or relating to a deity.
    4. Of or relating to the immediate exercise of divine power; miraculous.
    5. Of or relating to the miraculous.

    quote:
    WordNet definitions:
    adj : not existing in nature or subject to explanation according to natural laws; not physical or material; "supernatural forces and occurrences and beings" [ant: natural] n : supernatural forces and events and beings collectively; "She doesn't believe in the supernatural" [syn: occult]

    So, I note that this term also has a rather wide semantic range. In the American Heritage definition, numbers 1 and 2 make no reference to deities, divine powers or miracles. It all depends on what one means by the ‘natural world’ and ‘natural forces’.

    Likewise, the WordNet definitions include “not existing in nature” and ‘not subject to explanation according to natural laws’. Again, what precisely are meant by ‘nature’ and ‘natural laws’?

    And most fundamentally of all, who gets to determine the precise meaning of these terms? To my mind there is a distinctly post-modern feel to that question.

    As for the definition of supernatural as “not physical or material”, is human mind reducible to the physical or material? Is human consciousness? is human intelligence?

    We have ample evidence of human mind, consciousness and intelligence, and do not label them as ‘supernatural’. We also have evidence of some animal intelligence and, so I am told, even of single cell intelligence in some circumstances.

    So, the evidence of mind, consciousness and intelligence are undisputed in some situations. Who is to say that evidence of mind, consciousness and intelligence won’t be found in other, hitherto unsuspected, situations? And who is say for definite, one way or another?

    Real life now intervenes. This afternoon I have to go out on a short trip and I am likely to be very tired on my return. I may not be able to post in detail again until tomorrow.

    FS - I think the moot point here is that 99%+ of scientists are quite clear about what is and isn't science, and what is metaphysics. The phrase "scientific frame of reference" is therefore a useful shorthand to mean what 99%+ of scientists take it to mean.

    In the same way, ID seems to me to be a tiny group of scientists trying to redefine what falls into the purview of science and what does not. So far, they have not given the mainstream scientific establishment a valid reason to extend its remit into metaphysical speculation about the role of supernatural creators in the origins of natural phenomena. This is why the Wedge Strategy document is so damning; it exposes the real motivation behind this attempt to move science onto ground it has long considered ultra vires, as it were.
     
    Posted by Callan (# 525) on :
     
    This is as good a starting point for an account of what science is as any:

    quote:
    (1) It is easy to obtain confirmations, or verifications, for nearly every theory-if we look for confirmations.

    (2) Confirmations should count only if they are the result of risky predictions;that is to say, if, unenlightened by the theory in question, we should have expected an event which was incompatible with the theory-an event which would have refuted the theory.

    (3) Every "good" scientific theory is a prohibition: it forbids certain things to happen. The more a theory forbids, the better it is.

    (4) A theory which is not refutable by any conceivable event is nonscientific. Irrefutability is not a virtue of theory (as people often think) but a vice.

    (5) Every genuine test of a theory is an attempt to falsify it, or to refute it. Testability is falsifiability; but there are degrees of testability; some theories are more testable, more exposed to refutation, than others; they take, as it were, greater risks.

    (6) Confirming evidence should not count except when it is the result of agenuine test of the theory; and this means that it can be presented as a serious but unsuccessful attempt to falsify the theory. (I now speak in such cases of "corroborating evidence.")

    (7) Some genuinely testable theories, when found to be false, are still upheld by their admirers-for example by introducing ad hoc some auxiliary assumption, or by re-interpreting theory ad hoc in such a way that it escapes refutation. Such a procedure is always possible, but it rescues the theory from refutation only at the price of destroying, or at least lowering, its scientific status. (I later described such a rescuing operation as a "conventionalist twist" or a "conventionalist stratagem. ")

    One can sum up all this by saying that the criterion of the scientific status of a theory is its falsifiability, or refutability, or testability.

    The full document is here.

    I would have preferred to let the issue drop, but you have asked me a question. I found your post confused because you had shifted your ground. I found it confusing because I no longer know what ground you are standing on. Let me recap

    1. I observed that the Wedge Strategy was devastating. You replied that I should not mistake a PR strategy for the serious underlying scientific issues.
    2. I countered by questioning the need for any PR strategy, given that the aim was the publication of scientific ideas and put forward some classic arguments (later repeated by Callan) about the correct approach to this issue.
    3. You described my post as naïve and referred to your time in the nuclear power industry as an illustration that it was normal for scientists to have a PR strategy. This struck me as a confused and confusing shift of ground. The use of nuclear technology is controversial, subject to misrepresentation by pressure groups and it is perfectly sensible for the industry to invest in PR. That does not apply, in general, to the issues of pure science which are the chief domain of ID arguments.
    4. I observed that the PR strategy in the nuclear industry is concerned primarily with application and asserted the confusion in your post (which I have now explained from my POV).

    After reading your latest post, I wonder if you are aware of your tendency to shift your ground, since you have now done so again.

    Let me cut this Gordian Knot. You have not answered Callan’s point, my point, Karl’s point about the proper promotion and testing of scientific ideas. You have simply evaded all of us.

    Although I am not a practising scientist, I studied Chemistry at University before a career switch into IT. My understanding of the scientific method was formed by my studies and subsequently reinforced/refreshed by reading Popper. I am very happy to admit to being out of touch with the current social/economic pressures on research scientists, which may very well distort the purity of the processes. They have never been pure in practice – that is common ground. I also thought it was common ground that the world views and prejudices of researchers did not matter a row of beans. You can have whatever daft philosophical/religious/social ideas you like on these issues but if your science is good and your results replicable, testable and falsifiable, then you add soundly to understanding. That, essentially, is where I am coming from on this issue and, so far as I can tell, so is Callan and so is Karl.

    So, when you are up to it, perhaps you can address the following question? Why should some ID proponents require a Wedge Strategy in the form stated?

    I don't think that is common ground. Most people, I would have thought, would allow that the biases of researchers did influence the theories and models they developed.

    Perhaps it would be more accurate to say that the world views of researchers influence their models but are irrelevant to whether those models are finally adopted as part of the corpus of science.

    It probably isn't a coincidence that the theory of the Big Bang was originated by a Catholic Priest but the fact that it became the dominant model had nothing to do with whether Fr. Lemaitre's theology was widely shared and everything to do with the fact that subsequent discoveries in the field of astronomy and quantum physics tended to validate, rather than falsify the model.

    As far as science is concerned, if something is part of the framework of observable physical laws and objects then it is natural. Nobody has yet shown that there is anything with objective reality that sits outside those laws: this is the province of faith and religion.

    These are very simple, very straightforward concepts. They are near-universally understood, and very useful. Anyone seeking to redefine them had better have extraordinarily good reasons.

    quote:

    Mind, consciousness and intelligence have all been unequivocably observed in connection with physical laws and objects. This is science. They have not been unequivocably observed otherwise - this is religion.

    You get a lot more freedom to speculate in religion, but science needs more rigour to qualify.

    So, having established that science is the domain where physical laws and objects reside, and that religion and the supernatural is where you find things that cannot be shown to act according to physical laws nor share the nature of objects, may I now, for the final time, ask for you to explain Dembski's statements, in particular his apparent proposal that it is possible to introduce a mind unconnected with physical laws, and that acts in ways outwith the normal area of science, and still call it natural?

    It still looks like theology to me. How does it differ from theology? How would we check this?

    What on earth is Dembski saying?

    I have heard it claimed that the late 18th & early 19th French naturalists who saw evidence of evolution and/or catastrophic changes tended to be on the revolutionary side, whereas the Royalists prefered ideas of the fixity of species.

    Also that the early French evolutionists, such as Cuvier tended to be from Protestant (Hugenot) families.

    Its often been claimed that Darwinism is informed by 19th century English ideas of free trade, free markets, and business competition. Darwin of course was from a very wealthy big business family.

    It's less often - but still sometimes - noticed that Darwin (& his family) were political liberals and Wallace a non-revolutionary libertarian socialist & early feminist - they were people who believed in the need for political change, but looked for gradual change.

    But you are obviously right - although those political and cultural views inspired or constrained their scientific opinions, those opinions are still liable to be tested. And we don't reject what the lookout sees just because they are standing in a tower.

    On the other hand, if the combination of a belief in human progress with Protestant religion, political democracy, and free market capitalism naturally led to the theory evolution by natural selection, why are the only large group of educated people who still reject it Americans who share those very cultural values?

    The politics surrounding the science of biological origins has become a particularly hot potato, especially in the USA. Borrowing and editing one of your sentences, I could truthfully write: The use of [ID theory] is controversial, subject to misrepresentation by pressure groups and it is perfectly sensible for [ID theorists] to invest in PR.

    To illustrate what is at stake in the extreme politicisation of these issues, you may like to read the following entry from William Dembski's personal blog. In the USA, qualifications are on the line, careers are at stake, and the courts are now involved. If I found myself in those circumstances, I would welcome as much PR help as I could get.

    quote:
    4. I observed that the PR strategy in the nuclear industry is concerned primarily with application and asserted the confusion in your post (which I have now explained from my POV).

    I must disagree with you. The public is, in general, woefully ignorant of the scientific basics of nuclear physics, even before we get on to the really controversial stuff about dose limits, safety standards, waste disposal and the rest. That lack of basic scientific knowledge is one of the reasons why it is such a touchy subject with the public.

    BNFL Sellafield have a whole visitor centre dedicated to educating the public. Much of it is about basic nuclear physics rather than the specific detail of BNFL's work. It is now one of Cumbria's leading tourist attractions.

    quote:

    From my perspective the ground shifting is being done by people who throw ad hominem and other logically fallacious arguments into a debate about scientific issues.

    No argument from me against the general concept of Popperian falsibility.

    Again though, I think your last sentence represents an over-optimistic and somewhat naive viewpoint. "World views and prejuduces of researchers" may distort someone's perceptions to the point where their scientific work ceases to be accurate and truthful.

    The real world is messy and sinful - even the scientific world. A few years ago BNFL had to deal with the fraudulent falsification of safety documentation sent to the Japanese with some nuclear materials. Speaking more generally, fraud in academic scientific circles has certainly been indentified on occasion.

    Ken I understand your point. But my comment was in the context of the irrelevance of the views of scientists to the quality of the science they may produce. If their biasses mess up their findings and conclusions, then this will become obvious via the normal processes of replicability, testability and falsifiability, not by a test of their biasses. Unbiassed people (always supposing there are such paragons) can produce bad science and biassed people can produce good science, by the test of the scientific method. Which is, or should be, the only valid test.

    Faithful Sheepdog. Thanks for your answers. I'm still inclined to believe you shifted your ground but I'm gratified by what we have in common. My opinion stands that you are underestimating the damaging significance of the Wedge Strategy, but within the context of discussing ID science per se, you are clearly free to ignore it. I don't think its introduction by Callan was ad hominem. From a close study of its Phase 1, it seems clear to me that the ad hominen attack is from within the Wedge Strategy itself - and directed aggressively outwards. But we can disagree about that, without it affecting any discussion of the science per se.

    The three theses you cite sum up Rex's point admirably. Davison postulates that the evolutionary development of a species is somehow pre-ordained rather than determined by natural selection, an idea which can be simply dismissed by the two words "mass extinction"
    If you were more familiar with Davison’s ideas, you would find that the phenomenon of extinctions is one of the fundamental facts on which he bases his work. In his model, life-forms evolve through non-sexual reproduction and non-Darwinian means. Once sexual reproduction begins, it renders the life-form vulnerable to genetic deterioration and subsequent extinction.

    This is especially interesting because it plays directly into a typical conservative disdain for sex! Anyways, this does not seem to explain existing evidence well, for instance the fossil record of vertebrate evolution, nor does it explain why parthenogenic animals have apparently developed from sexual ones. To be credible as a scientific theory, it should first explain the existing data.

    quote:

    You will find that Remine subscribes to an old earth paradigm and his arguments are developed on scientific and mathematical grounds, particularly with respect to population genetics. He has defended his thesis in depth at the ARN forums. If anyone can rebut it competently he wants to hear from you.

    As a mathematics student, I must point out that for all its powers, even perfect mathematics does not prove anything about the physical world. There was some terrible "mathematical" ID text I read awhile back that was about the "no free lunch" theorem or somesuch. IIRC, the theorem itself was trivial, but as done by all good mathematical hacks, it was obfuscated to fill many pages.

    Once one has an equation, then one can see whether or not the physical world agrees with that equation. One cannot just make up an equation, and then declare that the physical world must agree with it.

    For instance, cladistics is a mathematical theory based on the idea of common descent and mutation with relatively little hybridization. The fact that cladistics models the tree of life so well tends to validate the assumptions that went into the model. It is worth noting here that, as one would expect if evolution by random mutation were true, non-coding regions of DNA correlate more strongly between organisms which are determined to be more related using cladistics based solely on physical appearance. So, this makes it a very good model indeed. I suggest you compare the application of mathematical models used in ID and biology if you want to see why one is not taken seriously. Unfortunately, most people cannot see mathematical crankishness, but if you look at how the maths have been spplied, then maybe you can see their value.

    quote:

    quote:
    ”The new data show that if more mutations show up at a gene, that gene tends to accept a higher percentage of those mutations.”
    That is not a result that anyone was expecting, nor can it be claimed as a prior prediction of neo-Darwinian theory. It may, however, be compatible with EAM ideas.

    Note it was not a prediction of EAM - it is just said to be compatible with EAM after the fact. It is a well-known crank technique to take every new data point that happens along and claim it fits your theory. Well, if your theory had predictive value, you could have told us about it before we actually saw it. I do encourage scientifically inclined people to spend time studying obvious cranks! For instance Crank.Net is a wonderful site. Spending so much time intrigued by cranks has taught me to be especially wary of certain lines of argument - and is helpful for spotting BS in areas outside my expertise. If I had not spent so much time amusing myself by making fun of cranks, I would probably not be nearly as pro-science as I am today.

    I know some forces that blind someone to scientific knowledge, since I avoided the ramifications of science to my origins beliefs for years. Sometimes it is partially fear of what ones peers would think, or suppose that one's salvation is even in question if one has doubts. An individual really told me that "If evolution is true, then God does not exist!" Sometimes it is just laziness, as when YECcies speculate that the speed of light is non-constant, but then can't be bothered to see what research has been done to check that out. (Answer: quite a bit - it's a really important problem in physics, but many tests have been done and no one can find any significant changes!) I think in your case you really do not want to believe evolutionary theory, so you store up information about possible alternatives. The way you have been debating suggests you don't actually believe these alternatives, merely find them interesting because they also disagree with what you find so ugly. Surely you are aware that the different ID speculations are mutually contradictory, so what exactly are you arguing for? Simply stating the beliefs of these other people is pointless - we won't be impressed, because we are not impressed by their names or their obfuscated language, and we can't argue with them because they aren't here. Tell us what you actually believe about the origins of species, and we can discuss your concerns instead of these Dembskis. And if your belief just comes down to a negative assertion such as "evolution is wrong", or "mutation is nonrandom", I suggest you strongly consider bringing yourself to a point where you can come to think through these prejudices.

    These are very simple, very straightforward concepts. They are near-universally understood, and very useful. Anyone seeking to redefine them had better have extraordinarily good reasons.

    Firstly, my apologies for the delay in getting back to you. Even when I do have some energy, real life has to go on and has to be fitted into the ‘energy gaps’. I am also on my own this week. Now to your post.

    I really do think you are begging a huge number of questions here. I am fully in favour of the Popperian concepts of observability, repeatability, falsifiability and refutability (as Callan helpfully posted). However, it doesn’t follow at all from a commitment to those concepts that “physical laws and objects” represents the whole of the truth about our world (which is what I understand by science).

    Your statement “Nobody has yet shown that there is anything with objective reality that sits outside those laws: this is the province of faith and religion” is very questionable. As a matter of fact I suspect that there are many everyday, ‘natural’ things that are not reducible to “physical laws and objects”.

    Consider human emotions – love, joy, fear, hate – or the contagiousness of laughter and mirth. Are they reducible simply to biochemical states in the brain? Are they simply governed by the laws of chemical interaction? Emotion and laughter are certainly real enough, but do they fall under your definition of science?

    Your statement also contains no less than three logical fallacies:

    Firstly there is an argumentum ad ignorantiam – an appeal to ignorance. No one can prove me wrong, so I must be right. Even if I accept that “nobody has yet shown…” is correct (which I don’t), it does not logically follow that “nobody will ever show…”

    Secondly, your statement presents a false dichotomy. Anything not science (as understood by yourself) is declared to be ‘the province of faith and religion’. The possibility that you have misunderstood science is not considered, as is the possibility that there remains much for science to discover. The argument here is a fiat on your own personal authority.

    Finally there is an argumentum ad populum - an appeal to the majority. That is no guarantee of truth. Even Karl’s post had a somewhat suspicious 99% figure - I wonder whether it is scientific? [Smile] – but still leaves 1% unaccounted for. As a matter of historical fact, Darwin’s ideas took many years to become the majority scientific viewpoint (at least in the English speaking world), but they have never been accepted by 100% of competent scientists.

    If you had said that as a convenient working convention some scientists make certain assumptions but without any prejudice as to the actual true reality of the world, then I might agree. But you seem unaware to the extent to which your viewpoint is defining in advance what the actual truth of our world is. As a result I am not surprised that you have had difficulty in understanding ID in general and Dembski in particular.

    You get a lot more freedom to speculate in religion, but science needs more rigour to qualify.

    I agree with your statement about rigour, but not much else. Many things have never been ‘unequivocally’ observed, but that doesn’t automatically make them religion. This is a false dichotomy again.

    So, having established that science is the domain where physical laws and objects reside, and that religion and the supernatural is where you find things that cannot be shown to act according to physical laws nor share the nature of objects, may I now, for the final time, ask for you to explain Dembski's statements, in particular his apparent proposal that it is possible to introduce a mind unconnected with physical laws, and that acts in ways outwith the normal area of science, and still call it natural?


    It still looks like theology to me. How does it differ from theology? How would we check this?

    What on earth is Dembski saying?

    (Here is Dembski’s article on ID in the forthcoming Oxford Handbook of Religion and Science to which Rex Monday has been referring.)

    I think to begin with you need to understand properly what Dembski is saying in relation to design and its detection. Remember that Dembski is a mathematician and a philosopher. His own work is about identifying design, understood as a property of physical objects, and defined in a particularly rigorous mathematical fashion.

    Of course, one consequence of that design identification is some postulation of ‘mind’ at work, but the identification of that mind with a deity or other divine powers is definitely not a necessary corollary of his scientific work. This is where many people are misrepresenting Dembski in particular and ID in general.

    Some, of course, may choose to see evidence for theism in Dembski’s ID work, but others are postulating hitherto unknown properties of our universe, and a few are attempting to elucidate laws of material self-organisation. Far from inhibiting scientific research, Dembski’s work has opened up many new lines of enquiry.

    I find that Dembski writes with clarity and is in general readily understandable, although some of his specialist mathematical work is way over my head. I have no problem seeing that his work is clearly scientific and not theological. I suspect that the roots of our very different opinions on this matter are that you and I understand ‘science’ very differently, and so we differ over what we think it should look like.

    quote:
    Ken said:
    That's really important if anyone is going to make sense of his rather baroque structure of supposed probabilities he's calqued on Drake's equation.

    Dembski’s work on the universal probability bound bears no relation whatsoever to Drake’s Equation. That contains some completely unknown and probably unknowable factors. It remains a theoretical curiosity of no practical use.

    By contrast, Dembski is arguing logically from known facts and the present cosmological consensus. He has attempted to determine mathematically and rigorously a limit to the ‘probabilistic resources of the universe’.

    In this respect I see some simple correspondence between his work and the quantum theory to which Rex Monday has already alluded. Just as matter is not infinitely indivisible, so in a likewise manner Dembski proposes limits to the creative possibilities of unintelligent processes.

    His full weight academic work The Design Inference is published by Cambridge University Press and was fully peer reviewed. That doesn’t automatically mean it is right, of course, but clearly someone thought his arguments deserved a hearing. As a Cambridge man myself, I am proud of my Alma Mater here.

    To be a credible commentator on Davison's work, you need to study it for yourself and cease making cheap superficial comments about conservatives and sex. He is far more able and sophisticated than you are giving him credit for. However, be warned, he is a grumpy old codger who doesn't tolerate fools gladly.

    As a former professional engineer with two mathematically-oriented degrees, I am well aware that mathematical models are meaningless unless they reflect physical reality.

    Please give me some reasons why the ID text you read was "terrible". The 'No Free Lunch Theorems' did not originate with Dembski, but his use of them has sparked a lot of debate.

    I have previously studied the whole area of evolutionary algorithms in some detail. These models incorporate ab initio the conclusions that some people wish to reach, and consequently tell me nothing about the biological world. Dembski was right - there is 'no free lunch'.

    Their ideas may or may not be borne out by future research, but one cannot attempt to test and possibly refute a scientific idea whilst simultaneouly claiming that it is not science.

    I think this is the root of your problem. This is an understanding of science I usually associate with the likes of Dawkins. Science is only a subset of knowledge and understanding about our world. There are whole swathes it does not and cannot cover, such as the nature of truth itself.

    Karl beat me to it, but that isn't what Popper was saying. Popper was saying that there is a particular intellectual enterprise for studying those physical laws and objects - called science - and that once you step outside that enterprise and have recourse to other concepts you enter the realm of metaphysics.

    There is nothing inherently wrong or irrational in talking about metaphysics. In fact the one major philosophical attempt to dispense with them - logical positivism - foundered on the key metaphysical assumption at its heart, to wit the statement that only empirically verifiable statements are meaningful - how do you empirically verify that?

    Karl seems to me right inasmuch as ID appears to be a mirror image of the sort of philosophy that Dawkins adopts. Dawkins' point goes something along the lines of: "Belief in God is not scientific, that which is not scientific is irrational ergo belief in God is irrational". The ID riposte goes something like: "That which is scientific is rational, belief in design is rational ergo belief in design is science". Both are based on a category error. In Dawkins' case the assumption that 'science' is a total description of rationality rather than a subset thereof. In the ID case that because a belief is rational it must, therefore, be scientific. Both hinge on the conflation between 'scientific' and 'rational'. For example, whatever one thinks of it the First Cause argument is a rational argument, the merits of which have been debated rationally by philosophers for centuries, but it has no place in a scientific work.

    Certainly do. Why shouldn't they? There are even fields of science, such as psychobiology, which investigate such things. I wouldn't say they were _simply_ governed by the 'laws of chemical interaction', but that's certainly a large part of the mix as decades of research into psychoactive drugs and their medicinal use shows.

    (It's 'no fewer' than three, by the way). And I was saying quite simply that nobody HAS yet shown these things. Nothing about the future - so you're guilty of a non sequitur in inferring an argumentum ad ignorantium, and a straw man fallacy in then arguing about that.

    It is a respectable position to say that one believes these things will be shown, and were ID to stick to this line and quietly get on with research to this end there'd be no argument. But ID says that it is _already_ sure of this, and is active politically to push this agenda, and this is not science.

    You were talking about the definitions of terms. I was explaining how I understood them - and it's a bit difficult to do that without saying what I think - and how the vast majority of scientists understand them.

    This isn't a matter for discussion, unless you can show either that I do not believe what I say I think or that what I claim to be the normal use of words is in fact not commonly understood. You are, I fear, mixing up the things themselves and their names (there's probably a posh Latin tag for that, but I don't know it).

    Indeed, it is impossible to divorce viewpoint from perception. Which is why science depends on objectivity, in finding things that are independent from individual perception and that can be tested regardless of viewpoint.

    What Dembski proposes is not that. He takes viewpoint - the mathematics of ID is the theology of John - and then says that therefore science must subsume itself to theology - the acting of mind outside the physical world. I understand that perfectly well. I do not understand how that is science. And I do not understand how you can say that Dembski's explanation, which you quoted, is 'crystal clear' in solving this dilemma, without a demonstration of what is being conveyed.

    No, you are committing another non sequitur. I don't say that everything that has never been unequivocably observed is religious, just that mind operating independently of matter has not been unequivocably observed and that believing that it does so operate is religious. Science could comfortably (or uncomfortably!) extend to encompassing such things, were they to be so observed.

    Dembski says that it should extend to encompassing such things and abandon the rules that define science in the process, without benefit of observation or logical demonstration.

    That's theology.

    The best way to save a drowning man is to throw him a lifebelt, not to say "What you need to do is find a way to get a lifebelt. Just like this one, in fact!" Just throw the blooming lifebelt!

    I'm reminded of an old urban myth from the days when mobile phones were rare, expensive and something of a status symbol. A businessman was on a train and had been yacking away loudly on his mobile for some time to the annoyance of all, when another passenger collapsed with what looked like a heart attack. "Quick!", said a woman, "Phone the ambulance, so they'll be there when we get to the next station!" The businessman ignored her. "Come on," said someone else. "Your conversation can't be that important. This man is dying!" Still the businessman pretended he hadn't heard. Finally, with exasperation and murderous looks, the phone was wrenched out of his hands... and turned out to be a fake.

    Does he misrepresent himself when he says that he is codifying the theology of the Logos from John?

    The political and theological motives behind ID are clear and have been explicitly stated. They would not nullify any scientific evidence - if there were any - but they do make it a fair candidate for extra-critical scrutiny, as has been said many times already.

    Dembski sees evidence for theism in his work!

    Science is perfectly happy looking for hitherto unknown properties of the universe and laws of material self-organisation. It does this without importing theological concepts.

    The trouble here is that ID claims to be science of the sort that is generally understood. You've just said that ID science is _somehow_ different to this, but without elucidating what it is.

    You see my confusion.

    I'm not going to get my paraphrase, am I? Well, I won't bother to ask again (jewish mother mode = OFF).

    It really was the _one_ thing I wanted, in my attempt to understand why people call ID science: an explanation in your own words of how _you_ thought it actually worked as science.

    Without a clear explanation of what I'm missing -especially when I've asked for it for so long and with as much directness as I can muster without smelling the brimstone - I fear I shall remain in the Realm of the Deeply Unconvinced.

    As far as I can see its application to evolution is near zero - of the 7 probabilities he multiplies 2 at the most are relevant to the problem, and all are obfuscated by his confusion (or misunderstanding) between timescales, which im my opinion makes the entire second half of that essay more or less useless.

    (Here is the link to the essay by Dembski.)

    I have previously read this essay in the past and I have just glanced through it again now. Note that this is only a fragment of his mathematical output, greatly simplified for consumption by the non-specialist mathematician.

    Overall I think you have misunderstood the reason he quotes the Drake Equation at one point. He does that, partly because I suspect the Drake equation is well known in some circles, and partly because he wants to highlight the essential difference between the Drake Equation and the one he derives and presents on page 39. At no point does he use the Drake Equation as the basis from which he derives his own formulation (which he terms the origination inequality).

    In Dembski's own words, with my emphasis:

    quote:
    Despite these interesting parallels between the Drake equation and the origination inequality—not least that both are used for discovering signs of intelligence—there is also a sharp difference. For the Drake equation to convince us that the search for extraterrestrial intelligence is likely to succeed, none of the terms on the right side of that equation must get too small. Only then will SETI researchers stand a reasonable chance of discovering signs of extraterrestrial intelligence. By contrast, with the origination inequality, to guarantee the specified complexity, and therefore design, of an irreducibly complex system, it is enough to show that even one term on the right side of the inequality is sufficiently small. With regard to the practical application of these formulas, this difference makes all the difference in the world.

    The problem with the Drake equation is that most of the terms cannot be estimated.

    By contrast, Dembski's own equation deals with the probability of achieving an irreducibly complex system originating by Darwinian means.

    I would be interested to hear further from you on the significance of his "confusion (or misunderstanding) of timescales" and why you think "its applicability to evolution is near zero".

    For example, his so-called synchronisation probability is based on the fundamental assumption that these things must all be randomly available at the same time - but what does he mean by "same time" here?

    Same time in an evolutionary sense - i.e. in the same species?

    Or same time in a population genetic sense, or in ecological time?

    Or same time in the lifecycle of an organism?

    Or same physiological time - when a certain set of reactions is going on, or a certain behaviour taking place?

    Or the same time in a cycle of gene expression?

    Very different questions.


    Actually there is another point - there is gene transfer and co-operation between bacteria, and things can get transferred from species to species in many circumstances. Though as he is talking about the "fundamental molecular machinery - i.e. stuff that presumably comes from organisms is ancestral to all present-day bacteria - we can't really have any clear idea what they did in the way of reproduction - trhe only way to reconstruct the unobserved evolutionary past is by comparing current lineages - with only one lineage there is no data - which brings us back to the interesting question of what he would accept as evidence as such phylogenetic modeling inherently assumes common descent.

    Anyway, the whole argument is based on the assumption that the parts of a complex structure must just happen to be randomly available before it can evolve by natural selection. Basically he starts off by saying that selection cannot take place - then he spends page after page proving that it can't, based on that assumption. Its really silly. And it just misses the point so badly. Like those party tricks where you "prove" 1+1=3.

    If you agree with Davison, post some links or suggest a book I'm likely to find, and I'll look into it - nothing really obvious on google that I see.

    I suggest you compare the application of mathematical models used in ID and biology if you want to see why one is not taken seriously. Unfortunately, most people cannot see mathematical crankishness, but if you look at how the maths have been spplied, then maybe you can see their value.

    I have previously studied the whole area of evolutionary algorithms in some detail. These models incorporate ab initio the conclusions that some people wish to reach, and consequently tell me nothing about the biological world. Dembski was right - there is 'no free lunch'.

    I was not talking about genetic algorithms at all, but I can discuss them if you wish. The point of genetic algorithms is this: we have this idea that complicated designs can arise through chance mutation and natural selection. Well, we need to test that assertion that complicated designs can arise in that manner. The easiest way to directly test the idea is to model it in a computer - and the fact of the matter is that these models have resulted in new and novel designs not thought of by the creators of the systems. The best known examples are probably a strangely-shaped antenna and a "bone-like" space truss.

    Yeah, you might not be impressed by these results. Computers are still pretty weak, after all, so it's hard to get anything really complicated out of them. The point is this: some guys had this hypothesis that complicated designs could be arived at by chance mutation, so they tested it, and it worked! This is a real, tangible accomplishment that the ID people haven't touched - if their ideas about the creation of complex designs are valid, then why haven't they created a toy model on the computer to test out the basic ideas?

    Anyway, when I was talking about mathematical models I was primarily talking about cladistics, those two previous paragraphs. Here's the idea: the complex design of animals was arrived at by chance mutation, until distinct populations no longer reproduce with each other. Since these mutations tend to produce differences in characteristics of the animals, we should get a pretty clean family-tree structure if we group them by similar characteristics.

    Cladistics incorporates these ideas into a mathematical model, which can be used to propose the best family tree from all the data of animal characteristics. In addition, it also includes a built-in check that lets us see how well the data is actually incorporated in the tree-structure: for the tree of life this is astonishingly good. Surely as someone who takes an interest in these matters you've read talkorigin's 29 Evidences for Macroevolution which discusses this more plainly than I could.

    What's most interesting is that because of its nature, I strongly suspect that just about any class of human-designed objects will fit very poorly into clades. No sarcastic comments please, but I am interested in the history of board games, and almost every book on the subject will tell you that, despite their best attempts, classifying games into such a tree-like structure is impossible, since nearly every combination of characteristics has been tried, and found relatively successful in some combination. And this seems to be true of human design in most areas I can think of. So, one could argue that since the only uncontroversially consciously designed objects we know about - those created by human individuals - fail to map into the cladistics paradigm, that the tree of life is in fact strong evidence against conscious design of animal life.

    Now compare those successful models against Dembski's "No free lunch" model. IIRC, the paper that I read basically presented something much like the first chapter of an introductory book on information theory. I certainly have nothing against information theory, since it is applicable in those fields in which it is used.

    However, the entire paper seemed to ignore the fact that in the natural world, information is just like entropy - the equations and concepts here are identical, and in general physicists and information theorists borrow language and ideas from the other constantly. The fact that entropy never decreases is identical to the fact that information never increases - that's all very clear. But he does not seem to recognize that the relevant pool of information consists of the entire universe - relative increases of information on Earth is paltry compared to the inevitable march of entropy across the universe. So the assertion that "there's no free lunch", when applied to the only object that we know is entropically closed, the universe, simply boils down to the fact that the initial entropy of the universe was astonishingly low! This is something everyone agrees on, and by no means does it say anything as to whether mutation can be the force behind evolution!

    To assert that, for instance, the genetic code can only decrease in information, is to assert that information cannot flow in from the environment. But this is exactly what evolution states: that information does come from the environment in the form of natural selection.

    (It seems like one of the problems with a lot of ID literature is that it cannot rule out the possibility that Evolution is the Intelligent Designer, much like the medieval proofs of God typically fail to distinguish Him from the Big Bang or the Universe at large.)

    In any case, here is the rub: Dembski's model does not seem to describe anything in biology the way that the models of genetic algorithms and cladistics do seem to!

    I think that's pretty much the context I was thinking in - to me it honestly seems that you are using these names to deflect criticism of your ideas. You stated somewhere that you wished that people would address the scientific issues you raised. This post of yours was the closest I found to that, which is why I responded, since I thought maybe you were not getting a fair hearing. Perhaps there is something more explicit, but I was not seeing where you wrote what exactly, positively, you believed. I apologize if I missed it - I have read all this thread, but perhaps lost the post where you explain.

    So all I know about your beliefs is that you think something is wrong with evolution, and to back this up you seem to be invoking a lot of names in the ID crowd. However, I can't tell what ideas of theirs, if any, you agree with.

    Well, the validity of their beliefs, whether or no, may be quite a different matter than the validity of your beliefs.

    Since these are public figures, a full discussion of these people's beliefs is probably not necessary on these boards. The only reason to discuss their beliefs is if you actually agree with any of them, because, hey, you do post and read here.

    So, please do me the favor of explaining to me, what exactly constitute your scientific beliefs about origins. Then maybe we can have more constructive discussion, since we will be talking about your and my beliefs, instead of Behe's and Dembski's.

    And again, I'm sorry if you've explained what exactly you think and I've missed it. My beliefs are pretty scientifically orthodox so it's probably obvious what I believe. All I know about yours is that you think I'm wrong! So what is the extent of our disagreement?

    I think this is the root of your problem. This is an understanding of science I usually associate with the likes of Dawkins. Science is only a subset of knowledge and understanding about our world. There are whole swathes it does not and cannot cover, such as the nature of truth itself.

    Here is my original comment:
    quote:
    However, it doesn’t follow at all from a commitment to those [Popperian] concepts that “physical laws and objects” represents the whole of the truth about our world (which is what I understand by science)
    I think my wording here was too loose and as a result I have misled you. For me part of our human vocation is to understand our world and our universe to the best of our ability. I see the realm of science as one of the tools to accomplish that task. Like you I do not automatically think that science in itself will ever be able to explain the whole of our world – that is simply asking too much of science, and other tools will be required.

    However, I do think that Rex Monday’s comment about “physical laws and objects” represents an arbitrary limitation on what can be discerned through the Popperian concepts of observation, repeatability, falsifiability and refutability. It becomes particularly important when repeatable and testable scientific observations suggest that there is indeed more to the world than “physical laws and objects”.

    That suggestion (never mind conclusion) seems to be anathema to some people on a priori grounds that are not themselves scientific. As a result the ID world has attracted ferocious political opposition, as well as many attempts to refute their work on scientific grounds. In the light of those attempts at refutation, the repeated denunciation that ID ideas are not science strikes me as itself fundamentally unscientific.

    quote:
    Rex Monday said:
    The best way to save a drowning man is to throw him a lifebelt, not to say "What you need to do is find a way to get a lifebelt. Just like this one, in fact!" Just throw the blooming lifebelt!

    I am sorry you feel that you are drowning. From my perspective I see several lifebelts in your vicinity, but you have turned your nose up at them all. I do not think that I can explain ID concepts to you any better than I have, but perhaps that is my failing.

    If you disagree with ID ideas on rational grounds, that is your choice, but I am genuinely struggling to see where your present confusion actually lies. I am clutching at straws, but I wonder whether it is the word ‘design’ itself. From my engineering background its meaning has always been intuitively obvious to me, but perhaps not to others. Is this so?

    Other than that I can only recommend more study of the work of ID world in their own words (and those of their few competent critics – most are not). You may also wish to spend time discussing ID ideas on the ARN forum (which is public access). The scientific and debating standard on that forum is high. Well-informed critics of ID ideas are welcome.

    quote:
    Rex Monday said:
    I'm reminded of an old urban myth from the days when mobile phones were rare, expensive and something of a status symbol. A businessman was on a train and had been yacking away loudly on his mobile for some time to the annoyance of all, when another passenger collapsed with what looked like a heart attack. "Quick!", said a woman, "Phone the ambulance, so they'll be there when we get to the next station!" The businessman ignored her. "Come on," said someone else. "Your conversation can't be that important. This man is dying!" Still the businessman pretended he hadn't heard. Finally, with exasperation and murderous looks, the phone was wrenched out of his hands... and turned out to be a fake.

    This anecdote was particularly revealing, especially the word “fake”. You have worked very hard to demonstrate that ID ideas, far from being science, are really disguised theology in the service of a political program (conservative, naturally). It is no secret that Dembski draws some theological inspiration from his scientific work, but that does not invalidate his scientific work any more than Dawkin’s aggressive atheism does his.

    For my part I remain utterly unconvinced of your thesis. I have no qualms that there is any widespread fakery or manipulation going on in the ID world – there are too many necks on the line for that to be the case and no one is getting rich - quite the opposite, in fact. If their ideas are scientifically sound, they will be accepted sooner or later as the repeatability, testability and refutability of Popperian science kicks in.

    For example, his so-called synchronisation probability is based on the fundamental assumption that these things must all be randomly available at the same time - but what does he mean by "same time" here?

    Dembski’s argument is centred around the availability of a new function that provides a selective advantage. Non-teleological natural selection can only work on a function that is present and operating (e.g. better eyesight or whatever). If the new function conveys an advantage it will be selected for.

    Non-teleological natural selection does not see into the future. In particular, it cannot work on the class of partially complete biological structures that remain totally non-functional until every last piece is in position. It must wait until the structure is complete and then select on the basis of the new function.

    This is the essence of the irreducible complexity argument. If you don’t accept ‘irreducible complexity’ as a concept, then Dembski’s argument will naturally not be convincing. For more background on this topic, see the extended discussion by biochemist ‘Mike Gene’ at TeleoLogic here.

    So, as far as I can see, the “same time” in question is the time when the gene begins to contain enough information for the new structure to become complete and functional during the creature’s life, and thus available to the operation of natural selection.

    The precise time in the life of the creature will obviously vary depending on the nature of the creature, when it acquires its genetic information, whether it can modify its own genes during its lifetime, and how it reproduces.

    The argument for ID isn't convincing not because the concept of "irreducible complexity" is unacceptable, but because no single example of irreducible complexity has been demonstrated. Natural selection does not see into the future, as you agree, and so can't select for features that have no current benefit but may have a future benefit (as opposed to artifical selection, where an intelligent breeder can select for currently non-beneficial features knowing that they will be useful in future breeds - though I've no idea if that's actually done, it's possible in principle). The problem for irreducible complexity is finding features that have been selected for that are "completely non functional".

Genetic algorithms are a neat mathematical technique that demonstrates the importance of intelligence, purpose and design for them to work properly.

I do not deny the facts of palaeontology, but their interpretation is clearly a specialist field wide open to debate and discussion.

    I have certainly studied much of the information at Talk.Origins. In general, it has too much of a polemical flavour for me to trust that they are dealing strictly with science. Much of the time they are doing battle with young earth creationists, which is not my position.

    A lot of their information is good, but much of what they present is questionable, and some is completely wrong. Their discussion on genetic algorithms was excellent in giving me information about the details and history of this mathematical technique, but extremely poor at justifying why it tells me anything at all about the biological world.

    I don’t deny that natural selection can cause some changes to the genetic code. The key questions are what kind of changes can natural selection cause, and how rapidly can it do so, and what other mechanisms are operating to modify the genetic code. It is clearly scientific to ask these questions rather than to assume in advance the answers.

    If you have the mathematical ability, then I encourage to read up in detail on Remine’s work in information theory, population genetics and (particularly) Haldane’s Dilemma. This dilemma is about the rate at which the genetic code can be modified. His webpage is here. He has struggled to find competent critics of his work.

    I think it’s important to remember that the title of this thread is “The Death of Darwinsm”, and not “The Destruction of All Kinds of Evolution and a Triumphant Return to Genesis Literalism”. I am not arguing against the current scientific consensus on the age of the earth (4.6 billion years). I accept that that ‘natural selection’ is operating in the biological world, and that some form of biological evolution has very probably taken place, at least in some circumstances.

    However, I am presently agnostic on the issue of universal common descent, and very definitely of the opinion that a random mutation/natural selection mechanism (plus some genetic drift) does not and cannot account for all the structures actually found in the biological world. In that sense I am strongly anti-Darwinian, as the title of this thread suggests.

    I am mathematically and scientifically literate with an interest in logic and philosophy. I am not proposing any new theories of my own, but I am interested in discussing those proposed by others with more specialist knowledge than I have. Since I am ill and permanently off work, I have had a lot of time to study up on this subject.

    The ID world has succeeded in comprehensively stirring the pot and shaking a complacent Darwinian establishment. Even if ID ideas are fully refuted in the course of time, the intense debate that is presently taking place can only be good for the long-term health of science.

Genetic algorithms are a neat mathematical technique that demonstrates the importance of intelligence, purpose and design for them to work properly.

    No they do not. They require a scale of success or failure for them to work properly. This can be done by intelligence and purpose or it can be done by simple natural selection with those that are not fitted to the conditions of the world simply failing to breed. Criteria for success are necessary, but this doesn't mean that some intellegent individual needs to be measuring them.

    An interesting thought experiment for anyone who feels that genetic/evolutionary algorithms do not accurately reflect mainstream evolutionary theory is to consider how one might design a computer model that does. In other words, how would one produce a model of mutation and natural selection that demonstrates the flaws in the idea by following all the rules but fails to produce the expected results.

    It would be a very positive thing to do. Has anyone done it? Or is there some philosophical reason why evolution alone among scientific ideas cannot be so modelled?

    Very well. As I understand it, you have a very strong belief that random mutation cannot produce the level of biological diversity that we see, which is why you are interested in ID concepts to explain that diversity. Yet, your doubt of random mutation is not itself based on the ID authors that you've read. If that is the case, could you explain what is your strong basis for this doubt?

    Since you seem interested in the cladistics "anti-design" argument, I will see if I can find any sources which directly deal with this, or do my homework and run some calculations myself. This is something I've been thinking of doing for some time, anyway, and I suspect it will be more productive for me than studying alot of ID. Of course, if I must research and code, this could take quite awhile!

    Except I suppose in those cases where non-functional copies of genes mutate to a new function.

    Cladistics is not an area of palaeontology that I am competent to discuss in detail. I am aware that it has in the past been a controversial subject in scientific circles. I do not deny the facts of palaeontology, but their interpretation is clearly a specialist field wide open to debate and discussion.

    Cladistics isn't really about palaeontology but about taxonomy and systematics. Which is important to palaeontology but most cladistics is done on living organisms.

    Its not really cotnroversial as such, in fact if anything it has completely taken over from other approaches to taxonomy. But like a lot of other ideas there are some people who push it too far.

    There are 3 or 4 "layers" of it:

    - a general approach to taxonomy which prefers to limit systematic names to "clades", (i.e. "branches" of the tree) instead of "grades" (twigs of the the tree that resemble each other) and tries to find family trees by examining living organisms. The fundamental point of it is that we can only observe the tips of the twigs of a family tree. Fossils are NOT the ancestors of living organisms (or at any rate we can't prove they are) they are just other branches of the tree. So if we want to construct a model of an unobservable ancestral organism (or gene, or protein, or anything else) the ONLY way we can do it is by comparing the organisms we can observe & assuming that things they have in common are more likely to have been present in their common ancestor. This is the way good systematists used to work anyway - cladistics summarises and formularises what was always best practice.

    - a set of jargon terms invented by the German entomologist Willi Hennig who was trying to import some philosophical rigour into what he saw as a field dominated by fluffiness and imprecision. For example, Hennig defines species as "the largest set of semaphoronts interconnected by tokogenetic relationships". Honest, that is a good definition - but you have to have the Willi Hennig Mental Injection before you know what it means.

    - a family of statistical methods for doing taxonomy, based on Hennig's work, and usually contrasted with other methods built round cluster analysis (sometimes called "phenetics" & popularised by Sokal and Sneath). Both kinds of methods have mutated and evolved and now have a life separate from that their creators envisaged, as they are packaged in software and used by thousands of people to analyse the information from genome projects & all sorts of research, including medical tests. Maybe hundreds of thousands - some of whom probably don't really understand what they are doing. Yes, when your doctor sends your blood sample off for a test, it is quite possible it will be analysed by a computer program written by a hippy mathematician from Wisconsin based on some ideas a very strange man in Hamburg had for drawing up family trees of wasps.

    - a general philosophy of classification and description. Which when taken to extremes has been hedl to do away with the possibility of ever ingfering anything about evolution at all.

    If you ever get the opportunity to read a book by Henry Gee called Deep Time do so. Or look at his website. Its not my fault that he looks a lot like me.

    NB - my arguments about ecclesiology with Ley Druid and others on other threads are because deep down inside I think I am a cladist, which is a good Protestant system of classification and quite different from nasty essentialist Catholic systems [Biased] That's not a joke incidentally. T a pre-Darwinian biologist, a species was defined by its essential nature. To post-Darwinian biologists, species are defined by their relationships to each other.

    Could be, but in all likelihood aren't. For one thing, we don't know a given fossilised organism had reproduced. For another, most species go extinct. Speciation is believed to mostly happen to small isolated populations, so it's actually quite unlikely that any given fossil comes from such a population, or was the ancestor of one.

    It's a bit like digging up an Anglo-Saxon grave. It's possible that the guy we find in there was the ancestor of white Zimbabweans today, and certainly he's representative of the ancestors of such people at that time, but it's highly unlikely that this particular individual is.

    Of course. But how do we know?

    Say I've got a leaf print from a Cretaceous fern. Most ferns die without ever producing a baby fern. The chance that that individual plant is the ancestor of any plant now living is so small as to be not worth bothering with.

    OK, so we spread it out to species - I say my fern fossil is an Osmunda of some sort from the Antarctic. I could speculate that the species it is a member of is in fact a real ancestor of one or more of the current species of Osmunda.

    But I can't know this. There could have been many other species of Osmunda alive at the time, and maybe another one was the ancestor of all the current species.

    Also - from the point of view of Hennig who was a star pedant of negative magnitude - all I have on my table is the fossil. The actual specimen. All I have out in the garden is one specimen of a living plant. Any work I do to establish the family tree needs to be done on those individuals, not on the species I believe them to be members of. An assignment to species is one of the results I'm looking for, not part of my data.

    So what the true-believing cladist does is to collect lots of specimens, alive or dead, and assume that none of the specimens are ancestral to any others, and make trees connecting them all to a putative common ancestor of all the specimens. And that the common ancestor is a hypothesis, not an observation. It is statistical, derived from many observations, and different methods or different workers will construct different ancestors.

    Or, more controversially, every few months someone says they have dug up a fossil ancestor of modern humans from somewhere in Africa.

    But have they? Have they found an ancestral species? Or perhaps a sister or a cousin or an aunt species? How can we ever tell?

    It is my understanding that strict Darwinism sees evolution as driven by a combination of random mutations and natural selection in an unguided and undirected process that is non-teleological. That is to say, it is a process that has no goal or purpose in mind, but rambles aimlessly and accidentally through genetic code space with natural selection (and some genetic drift) doing the rest and ensuring that all the various ecological niches are filled as environmental pressure permits.

    I have doubted this for many years, but it is only in recent times that I have begun to look at it more closely and study it in a more scientific fashion. Reading Richard Dawkin’s book ‘The Blind Watchmaker’ was very revealing, as was Neil Broom’s reply ‘How Blind is the Watchmaker?’

    In particular, Neil Broom’s reply introduced me to the concept of ‘information’ that transcends a simple materialist explanation. A printer’s interest in a book might be to examine the paper quality, the ink chemistry, and the printing technology, but I buy a book to read it. That is information.

    With Dawkins’ famous “Methinks it is like a weasel” model of cumulative selection, he uses a teleological process (i.e. one that clearly knows where it is going) to illustrate a supposedly non-teleological process. To be fair, he later recognises this, but then retreats into his normal bombast and rhetoric without any significant substantiation of his position.

    The final clincher for me was the extensive study of genetic algorithms that I undertook last year. In my opinion these algorithms produce impressive results because they are the product of a teleological environment, made up of the researcher’s mind, the operating system of the computer, and the design of the software programming.

    There is absolutely nothing random or accidental about the way these algorithms wander through the relevant search space – that is all programmed in. By having the search goal specified in advance, these algorithms are being given access to information that strict Darwinism eschews. With all these helping hands it is not surprising that they work.

    To be honest, I was really astonished to see that some Darwinists were citing these algorithms as support for their position. In my opinion they provide evidence in completely the opposite direction. I had already developed a lot of sympathy for ID ideas before I undertook to look at genetic algorithms, but once I had done so, ID ideas made even more sense to me than before.

    The only way that there may be some reconciliation between Darwinist ideas about natural selection and the evidence from genetic algorithms is if there are some hitherto unknown teleological properties of the environment. In other words, that environmental pressure is somehow aware of where it wants the evolutionary process to go and ensures that the genome is manipulated accordingly. Despite the scientific evidence for it, that idea is deeply anathema to some people and consequently has been resisted tooth and nail.

    I am certainly interested in hearing more about the cladistics “anti-design” argument. Anything you can come up with would be appreciated.

    For the study of ID ideas, if you have the mathematical ability, I encourage you to read Dembski’s full weight academic work The Design Inference and the series of papers he has published at his own website on the Mathematical Foundations of Intelligent Design. These writings are aimed at the heavyweight mathematical specialist and were mostly over my head.

    Rex Monday, you are asking the right kind of questions. Richard Dawkins asks something similar in ‘The Blind Watchmaker’ after he coyly admits that his cumulative selection model actually incorporates something to which he is deeply opposed. Others have also asked the same question.

    I think the huge problem is how one designs a piece of evolutionary software to produce results (an inherently teleological process) to demonstrate that a non-teleological form of evolution can produce results. To my mind it is akin to the riddle of Epimedes the Cretan who said, “All Cretans are liars”. In other words, a logical and philosophical self-contradiction.

    You may wish to look into the AVIDA software that was featured in Nature Journal. It has also been extensively discussed at both the ARN and ISCID forums. AVIDA is much more sophisticated than a normal genetic algorithm, but does it get round the non-teleological barrier? Does it simply incorporate into its programming the conclusions that some have already reached by other means? I certainly think so.

    I'm afraid that that says more about your understanding of Darwinism than it does about Darwinism itself. The "goal" of any organism is to pass on its genes and to help its species prosper. Either that, or to become immortal (which is more than slightly impractical). The reason this is the goal is that organisms which do not do this tend to die out.

    The Weasel model is a bad one. Fair enough. I'm not arguing. (More accurately, it is targetted extremely low, and is about as effective an analogy as describing the sun as a big ball of fire).

    Genetic algorithms are about people using mutation & artificial selection to solve softeware problems. They dervice from biology, not the other way round.

    You sound as if you are both confusing them with the quite different practice of using software to model genetics. Not the smae thing at all.

    No, you’re confusing issues of individual survival with issues of evolution. The gene must be manipulated in the right manner for the evolutionary process to continue. That process must form new structures and achieve new functions. It must be inherently creative.

    I think you’re drawing a false dichotomy between what a human designer might find and what a genetic algorithm might find. Since computers can do calculation so much faster than humans, they have made possible numerical calculation methods that previously remained as theoretical curiosities. The genetic algorithm is a human-constructed tool that enables a more effective and efficient search.

    When you use the phrase “evolution would come up with a solution”, you are anthropomorphizing a process that in strict Darwinism has no mind or intelligence associated with it. This kind of loose language has a long history on the part of Darwinian apologists, starting of course with Darwin himself.

    I think you’re misunderstanding completely what the word ‘teleological’ means. The fact that you’ve misspelt it twice does not give me confidence. Here is the definition of teleological at dictionary.com.

    A good example of a non-teleological process is the erosion of the cliffs under the action of the waves. That is a process governed completely by the laws of physics. It requires no sense of purpose to explain it fully.

    A good example of a teleological process is the way your personal thoughts are turned into a post on the Ship that appears on my screen via a beam of electrons. That is a process that cannot be fully explained by the laws of physics. It requires a (human) sense of purpose to explain it fully.

    Non-living matter has no sense of purpose and consequently no will to survive, in complete contrast to living matter. The will to survive is an empirically observable fact, but Darwinism has no explanation for where that will to survive came from in the first place, even though it plays an essential part in the theory.

    I think you have misunderstood the term ‘search space’. The word ‘space’ is not being used here with a physical referent. I was using it in a technical mathematical sense to refer to all possible configurations of a gene (and that’s a lot of configurations).

    Some of these configurations will correspond to some form of viable life (with or without a selectable advantage), but the vast majority will simply be so much biochemical rubbish. The genetic code is specified and precise; it is not infinitely manipulable, any more than the letters in a piece of literature are if it is to remain intelligible.

    Animal and plant breeders use human intelligence. Have they yet produced any novel anatomical structures or functions that are viable in the natural world? A generously-producing milk-cow is still a cow, and winter wheat is still wheat. I doubt that an unintelligent process can do any better.

    I'm not sure why you think genes need a goal - even Dawkins at his most metaphysical seems to recognise the limitations of his "selfish genes" description. It is a simple fact that populations of organisms that reproduce at a rate equal to or greater than the rate they die will persist in the ecosystem; those that fail to meet that reproduction rate will eventually disappear from the ecosystem. There's no conscious "goal" required, which doesn't of course mean that some organisms don't possess such an instinct to reproduce.

    What sense of purpose is needed to fully explain the observation I made above about reproduction? Where does it deviate from being governed completely by the laws of physics (albeit physics encapsulated in chemistry, biology and other branches of scientific research).

    The evidence clearly points to the answer "an awful lot of creative power". In the absence of teleology, genetic mutation will occur in a random manner (there are all sorts of probability functions that predict certain mutations are more likely than others - just as in nuclear fission some products are more likely than others, and no one disputes the randomness of nuclear fission because of that). No one here seems to dispute that. In the absence of teleology, many of those mutations will result in novel genetic combinations. In the absence of teleology, some of those novel genetic combinations will result in greater reproductive success and become increasingly common in the descendants of that creature - others will result in reduced reproductive success and become increasingly less common. Thus, by non-teleological processes, novel genetic combinations are created. Looks like a form of "creative power" to me, all non-teleological.

    quote:

    Well, given that we've only been in the artificial selection game for a few millenia you might have to wait a while until we catch up with a billion years or so of natural selection. Besides, it begs the point of what constitutes "novel anatomical structures or functions". Would visiting aliens, ignorant of the artifical breeding that created them, consider all the breeds of dog to be the same species?

In other words, how would one produce a model of mutation and natural selection that demonstrates the flaws in the idea by following all the rules but fails to produce the expected results.

    It would be a very positive thing to do. Has anyone done it? Or is there some philosophical reason why evolution alone among scientific ideas cannot be so modelled?

    Rex Monday, you are asking the right kind of questions. Richard Dawkins asks something similar in ‘The Blind Watchmaker’ after he coyly admits that his cumulative selection model actually incorporates something to which he is deeply opposed. Others have also asked the same question.

    I think the huge problem is how one designs a piece of evolutionary software to produce results (an inherently teleological process) to demonstrate that a non-teleological form of evolution can produce results.


    I wouldn't call the act of designing a computer program 'teleological' - plain design is fine - but even if you want to say that, there is no problem in modelling non-intelligent systems in a designed system. If the weather, why not evolution? Is a weather simulator any more or less 'teleological' than an evolution simulator? Is a simulated weather pattern somehow imbued with teleological attributes? If not, why would a simulated evolutionary pattern need to be?

    You may wish to look into the AVIDA software that was featured in Nature Journal. It has also been extensively discussed at both the ARN and ISCID forums. AVIDA is much more sophisticated than a normal genetic algorithm, but does it get round the non-teleological barrier? Does it simply incorporate into its programming the conclusions that some have already reached by other means? I certainly think so.

    Neil

    (You haven't answered the original question. I'll get back to that later)

    I brought up Avida some time ago.

    So why can't evolution be modelled? Nobody seems to have a 'huge problem' in building these models, and they certainly seem to work. Where is the logical flaw? Your philosophical flaw only exists if you assume that evolution = design and design = an intelligently guided process, which is just restating your objections.

    What Avida (and others like it) do is model evolutionary theory - that's the limit of the intelligent input to the design process. The random element which modifies the 'life' inside Avida is outside any sort of predetermined path, and the survival of the modified 'life' is an entirely mechanistic process.

    Neither randomness nor mechanistic filtering requires an intelligent input. In fact, the state of computer art is such that there is no way to imbue a computer with intelligence: once you start the run, it's a machine. Whatever is going on in the computer is a randomly-driven mechanistic process and that is all. It cannot be anything else.

    Let's put it another way. I assume that you don't disagree with the Avida designers when they say that they have implemented standard evolutionary ideas in their software. I also assume you don't disagree with their reported results, with systems created that embody novel functions in unexpected ways and some of the resultant constructs being remarkably complex (certainly meeting the ID tests for CSI or whatever). They evolve new functions, often co-opting old functions in new ways, and end up as working entities that are vastly different to anything a human would have designed.

    These are matters of fact, checkable by simple inspection.

    So where does the creation of complexity come from, given that a current computer by its very nature cannot exhibit intelligence no matter how creatively we program it?

    Now, what would happen if the Avida creatures used as the starting point were made steadily more like biological creatures before each run? Would you expect them to somehow stop following the hard-wired evolutionary rules of the mechanical simulator at some point - and which point would that be? As the quality of Avida approached an accurate simulation of real life - this is a thought experiment, so don't worry about practicalities - at what point would the evolutionary model break down?

    Anyway. That's by the by. My original question wasn't about that - it was about how the non-Darwinian models could be tested, or how the evolutionary model could be shown to be wrong through computer simulation.

    By your arguments, it should be simple to do this and impossible to do what Avida does - yet the reverse appears to be true.

    How would someone build an Avida for the non-Darwinians? It would be a very positive thing to do.

    Sorry for posting more, but a thought just struck me. The Cretan Liar paradox is only a problem [b]if you assume that Avida produces correct results derived from invalid premises[b]. That would indeed be paradoxical.

    Paradoxes are always the result of incorrect assumptions. The assumptions of the Cretan Liar paradox are beyond me (I can hack it if I think very, very hard) but it is a far simpler task to resolve the Avida paradox! Just assume it does what it says it does.

    I'll respond to your other points in due course, but just to explain the Cretan liar riddle, which I think is also is called Epimedes' paradox. Note that I missed out an essential 'always' in my earlier post - apologies for any incovenience caused.

    quote:
    Epimedes the Cretan says, "All Cretans are always liars".
    .
    Given that Epimedes is a Cretan, and that he speaks about all Cretans, could his statement "All Cretans are always liars" ever be true?

    If his statement is true, then he must be lying, since he is a Cretan and all Cretans are always liars. So his statement cannot be true.

    But on the other hand, if his statement is false, then not all Cretans are always liars. So he may be telling the truth and his statement could be true.

    So we have a statement that cannot be true and yet could be true.

    Epimedes' Paradox is part of the class of self-referential statements that are logical absurdities and consequently have no meaning. They bear some relation to circular arguments in which the argument adopts as an essential premise that which it seeks to prove true.

    Well, I was actually thinking about how it relates to Godel's Incompleteness Theorem, which I've always found one of the most fascinating, obvious yet elusive aspects of logic. I can, if I read up about it and do a lot of beard-scratching, give all the appearances of understanding what it's about, but I really don't know what it means about the limits of deductive logic. Except that it clearly does mean a great deal.

    I blame an early exposure to "Godel, Escher and Bach". I got bored with Escher, will never be at ease with Godel - and I can't even pronounce Entscheidungsproblem - but will give thanks to whichever deity (apparently Protestant) had a hand in Bach.

    Perhaps that's why I hang out on Dead Horses (*). Variations on a theme can sometimes be profoundly beautiful in ways that the theme itself can never reach.

As far as we can tell, different species use different encodings to their DNA - and one of the areas humans save on is a need to regulate the homeostasis of a developing foetus- the mother does that using her standard algorithms. (And I am a trained mathematician).

    That doesn't prevent attempts to manipulate it at random from taking place. It just means that stillbirths and non-viable foetuses are comparatively common.

    What do you mean by an intelligent process? Also, what do you mean by a novel anatomical structure? Standard evolutionary theory would say that there almost aren't any - simply new uses for old structures which slowly change shape to better perform their new role. At no specific point can the species be considered new, even tho it bears little resemblance to what you started with.

    You sound as if you are both confusing them with the quite different practice of using software to model genetics. Not the same thing at all.

    The genetic algorithms being discussed here are a numerical technique for solving a certain class of scientific and engineering problems. They are not to be confused with the specialist biochemical software used by geneticists and others.

    Their development was inspired by evolutionary biology and their success at scientific problem solving has been cited by some as evidence for the correctness of Darwinism. I think the cart is being put before the horse here.

    quote:
    Alan Cresswell said:
    The evidence clearly points to the answer "an awful lot of creative power". In the absence of teleology, genetic mutation will occur in a random manner (there are all sorts of probability functions that predict certain mutations are more likely than others - just as in nuclear fission some products are more likely than others, and no one disputes the randomness of nuclear fission because of that). No one here seems to dispute that. In the absence of teleology, many of those mutations will result in novel genetic combinations. In the absence of teleology, some of those novel genetic combinations will result in greater reproductive success and become increasingly common in the descendants of that creature - others will result in reduced reproductive success and become increasingly less common. Thus, by non-teleological processes, novel genetic combinations are created. Looks like a form of "creative power" to me, all non-teleological.

    This is where the argument looks hopelessly circular to my eyes. The evidence points to "an awful lot of creative power" because of an a priori assertion that a non-teleological Darwinian process can be so creative.

    Genetic mutations certainly occur, but the more fundamental question is what kind of genetic manipulation is necessary in order for the evolutionary process to move forward. Can a random mutation provide the appropriate raw material for natural selection to build new structures and new functions that previously did not exist?

    In other words, can they provide for qualitative change (e.g. new functions or new limbs or new organs) as well as quantitative (enhanced features or bigger limbs or more-efficient organs)? I think Darwinism completely begs the question at this point with circular arguments and an unsubstantiated appeal to gradualism.

    So, the only way I can see a process of random mutation being so creative is if the mutation is of such a calibre that the offspring are very different from the parents, in a far-reaching qualitative manner - e.g. the parents were totally sightless, but now the offspring have complete eyes with all the anatomical, biochemical and neurological apparatus necessary to sustain vision.

    For this to happen, the random genetic mutation must be of a very particular character given the very precise constraints on the genetic code. It must also fortuitously coincide with a particular ‘opening’ in the environment for it to be selected. I am not credulous enough to accept that such creativity happens by itself.

    Introduction to the Mandlebrot set. I see lots of pretty shapes with recurring patterns. These shapes are the serendipitous results of an algorithmic process specified in advance.

    Pi is a transcendent number with an infinite number of decimal places. The decimal places of pi display no patterns at all; rather they are completely random. In the days before calculators and random number generators, the decimal places of pi were used as a simple random number generator.

    This reply indicates that there is a fundamental difference in the way we think about this issue. When I see natural rock formations that bear any resemblance to these sculptures, I will have more belief in the creative powers of natural processes.

    The patterns visible in cliff rockfalls and snowflakes are of a different order (qualitatively and quantitatively) from the genetic code patterns needed for viable life. The whole concept of genetic information is relevant here. That is why Dembski has attempted to provide the mathematical tools to decide between the simple patterns of unintelligent processes and the complex patterns that display evidence of teleology and intelligence.

    By “inherently creative”, I mean displaying the ability to further the evolutionary process by taking one type of cell/organ/system/body-plan/whatever and producing another qualitatively different type of cell/organ/system/body-plan/whatever.

    If all life began as single celled amoeba-like creatures, and has ended up with what we see today, then there has obviously been some huge evolutionary innovation en route. At some point there must have been new ways to process oxygen; new ways to eat and excrete; new ways to move, walk, swim and fly; new ways to reproduce (sexual organs); and so on. That is what I mean by “novel anatomical structures and functions”.

    I am using the word “creative” in the way I would use it of a creative human process, involving problem-definition, problem-solving, and solution-implementation transcending anything that random trial-and-error can achieve. That’s what I mean by an “intelligent process”. It is not explainable by a simple recourse to the fundamental laws of physics and chemistry.

    I think that the process of design inherent in any software development is by nature teleological, manifesting a clear sense of human purpose towards a specific goal. The software would not even exist at all without human involvement and specification. A computer model is only doing calculations to order. Whatever results the software produces are therefore a product of human purpose.

    Computers can produce all sorts of fictional results - see digital technology in films. However, a serious computer model incorporating the scientific understanding of, say, weather is only as good as the prior scientific understanding (and may be much worse due to a necessarily simplified model, poor programming and faulty data).

    If there are any deficiencies in the scientific understanding of weather, then the results from even the best model will invariably reflect those deficiencies. To ensure that those calculations reflect physical reality, the model must reflect physical reality as accurately as it can.

    If the prior understanding of physical reality is not correct, then a computer model will not say so directly, but it will still run. The inadequacy of the model will only become clear when its results are back-checked against physical reality. “Garbage in equals garbage out”.

    The underlying physical reality of true natural history must first be determined and described by an adequate theory. Once that happens, an accurate model of the true physical processes may make empirical predictions that, once verified by observation, will help to substantiate the underlying theory even further.

    Mea culpa. It was not working on code rather than not using computers.

    And I would say that given sufficiently large resources (the proverbial "infinite number of monkeys"), there is no solution that will not eventually be found by trial and error.

Assuming that as technology gets better, evolutionary modelling can get closer and closer to matching the actual details of real biological and environmental systems. At what point will the apparently successful model break down? What are the limits to the standard evolutionary model that you can see but evolutionary biologists cannot?

    Well, yes. There's usually a lot more involved. But simulations are very handy along the way. I'm not aware of any branch of science that doesn't use them in some way, and Avida is entirely in keeping with standard practice.

    So, assuming that non-Darwinian people are working towards a theory - what sort of simulation might help them? I cannot begin to imagine how this might work... and the complete absence of any such simulation only confirms me in my suspicion that there is no such theory and non-Darwinian objections to evolutionary biology are not science.

    However, I'm very eager to find out how I might be mistaken in this, by hearing some thoughts about how such a simulation could be approached.

    The software exists to implement an algorithm. Presumably it has so many lines of code to implement this algorithm properly, in a way that is user-friendly. If you have written complex software before, then you are aware that the majority of code deals primarily with such boring issues as reading/writing data files and interacting with the user. Only a small proportion of code (and really none of the OS) typically underlies the algorithm itself. Are you ascribing intelligence to this algorithm?

    No, not at all. The physical operation of a computer running a piece of software is is an unintelligent process and governed solely by the laws of physics, but it is an unintelligent process only explainable as the product of a priori intelligent process.

    The AVIDA algorithm has no doubt been programmed with great sophistication. The functioning of the software (as well as the computer’s operating system) is therefore fully determined by human intelligence. Until computers spontaneously start generating their own software, I will find it difficult to see AVIDA (and its results) in any light other than a human artefact.

    I know that computer crashes can corrupt files, but has anyone ever seen this as a creative process, even occasionally? In my experience it usually means a software reinstallation as the air turns blue, and not the celebration of some wonderful new feature in the software. [Smile]

    Actually, I am very confused by this entire section. Perhaps it would help me if you can explain why the following (non-random) mutation of your words does not produce an homologous argument:

    I believe that [the Earth] has something like [3.5x10^51][nuclear particles]. In my opinion that provides the [planet] with a huge amount of up-front intelligence. There is also all the information resident in the [physical laws] of the [universe], without which the [planet] would not run and the [physical] creatures (in reality, [collections of physical particles]) would not exist.

    In that respect I don’t think [the Earth] represents a meaningful model of Darwinian evolution or biological reality at all. The scope of the permitted evolutionary variation within each [physical] creature is laid down in advance by the [physics]. [Physical] creatures with more sophisticated functions are rewarded with more [offspring], so it is no surprise that more sophisticated [species] develop.

    The fundamental difference is that an AVIDA digital creature only exists within inside a human-created computer. We know for certain that they are the result of an intelligent process decided by human will. The programming of AVIDA no doubt took great skill and a lot of debugging, but it didn’t just happen – it was the product of human agency.

    By contrast, the universe and the earth certainly exist, but to my knowledge no serious scientist has ever suggested that they exist as digital creations in the equivalent of a gigantic computer core. That sounds like an idea from the film The Matrix [Smile] . We do however assume that the universe will be at least partially intelligible to us through scientific endeavours.

    AVIDA has all sorts of documentation to explain how it was programmed and how it works, but we had no such prior scientific information about the universe and the earth (unless one is a YEC, of course – I’m not). As humans it is up to us to find that scientific information for ourselves.

    I think your homologous argument also breaks down on the subject of information. 3.5 x 10^51 nuclear particles do not necessarily provide any information, any more than 3.5 x 10^51 letters provide information. In literature the key question is whether the letters are arranged in a way that corresponds with the laws of language, otherwise the result is meaningless garbage.

    In the same way, the layout of the code in a computer program has to be precisely right, or the program won’t even compile. It also has to be closely debugged to ensure that it is doing what the programmer requires it to do. The word specification is relevant here.

    I particularly recommend some further study on Dembski’s concept of specification, which plays a key part in his ideas. This heavyweight paper takes his ideas further and now gives specification a rigorous mathematical definition, as opposed to his earlier qualitative definitions.

    I believe that the assertion is on your side that it can not be so creative. The Darwinian argument here is along the lines of the infinite number of monkeys.

    Gradualism is an essential part of Darwinian theory, even in its Punctuated Equilibrium variation. The burden of proof is definitely in the Darwinian court at this point. Even Darwin recognised this point, but did not rise to it, when he wrote:

    quote:
    “If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.”
    The age of the earth is it is finite, and not infinite. But even if it had an infinite amount of time, that does not render possible an intrinsic impossibility.

    Justinian said:
    New functions can trivially be shown to happen- see the giraffe's neck for one example. Also look at the vast variety of domestic dogs.

    The giraffe’s neck and dog breeds are not examples of qualitative change – it’s still a neck, and they are still dogs. It is the more far-reaching qualitative change that remains to be demonstrated.

    quote:
    Justinian said:
    Why??? Absolutely no one else here sees any need or desire for that to happen at all.

    Nor is anyone else. No one else thinks it happens that way at all.

    The falsification of gradualism is a consequence of the irreducible complexity argument (assuming that one accepts it – I know you don’t). The idea that qualitative evolutionary progress has been by leaps and bounds is called saltation and has been around for a long time. It is also an essential part of Davison’s contemporary hypothesis. This form of thinking has also been described as “hopeful monsters”.

    Justinian said:
    There are lots of patterns in the digits of Pi - but they are short range and an artifact of Pi being a pseudorandom number.

    I think we differ in what we mean by arithmetical “patterns”. I am thinking of something that could reduce the infinite digits of pi to a formula that is much shorter than a long lists of digits. I believe that the mathematical term for this is ‘compressibility’.

    I am told that flipping an unbiased coin several hundred times will often generate strings of six or seven heads in a row (or tails in a row) – a result that is far from intuitive, but true nonetheless. As far as the overall result goes, I would not call that a pattern, but it may be what you are referring to as a “short range pattern”.

    What do you mean by a “pseudorandom number”?

    Ah, good. We're getting somewhere. What are these flaws? Are they implementation or design flaws?

    See some of my response above to Sleepyhead. I think it’s also worth repeating what the AVIDA people say about their own program (from here).:

    quote:
    Avida is an auto-adaptive genetic system designed primarily for use as a platform in Digital or Artificial Life research. In lay terms, Avida is a digital world in which simple computer programs mutate and evolve.

    Avida allows us to study questions and perform experiments in evolutionary dynamics and theoretical biology that are intractable in real biological system.

    The AVIDA people have been quite clear on the Internet that their program does not attempt to capture all essential aspects of biological reality, but is a research platform incorporating a much simplified model in order to facilitate study of certain aspects of evolutionary theory as it applies to artificial life.

    From the Lenski et al. paper in Nature:

    quote:
    “We examined the issue using digital organisms – computer programs that self-replicate, mutate, compete and evolve.”

    “These findings show how complex functions can originate by random mutation and natural selection.”

    So, AVIDA does not model any biological processes directly, but then it did not set out to do that. The model certainly works and the digital life-forms show evolutionary progress in performing more complex functions. There’s no argument from me on these basic facts – the flaws lie elsewhere.

    To my mind the success of the program is simply an artefact of human design and the product of programming skill. The programming rewards each step of the way as the digital creatures evolve towards the most complex function. When the rewards for these intermediate stages were stopped, the program consistently failed to evolve the most complex function.

    Lots more short critiques of AVIDA here and longer critiques discussing its relevance to the irreducible complexity argument here and here.

    quote:
    Rex Monday said:
    You've just described evolution! I thought you didn't believe that worked?

    There’s no argument from me that variation (whether random or non-random) followed by natural selection can generate some evolutionary change, such as the resistance of bacteria to antibiotics. The key question is whether this mechanism alone can explain the present diversity and complexity of biological life.

    I stand by my remarks. I think your response here shows that we have very different perceptions of what any computer model can do to support the validation of a theory.

    Firstly, note your use of the phrases “best guesses”, “what we think [it] looked like” and “the results compared with what we now see”. There is no guarantee that the results of any computer model will match “what we now see”. Even in the pre-computer era, the discrepancy between calculated results and (accurate) observed results indicated an inadequate theoretical understanding and/or mistaken calculations.

    Guesswork and speculative thought certainly have their place in asking questions, proposing a hypothesis and formulating a research strategy. An accurate computer model of the proposed ideas may indeed help the research strategy – I don’t disagree there at all – but it cannot of itself determine whether those ideas are true or false.

    Personally I do not see any way round the philosophical conundrum that any computer model is the product of an intelligent human mind. How could such a model ever then conclusively demonstrate that intelligent life evolved in the absence of an intelligent mind?

    I am reminded of another sage aphorism from my personal experience of computer models: “To forgive is divine, to err is human, but to really screw things up you need a computer.” [Smile]

    Your question reminds me of the holographic life-forms in Star Trek Deep Space Nine. Most were not sentient and self-aware, but as a plot device one or two were given such characteristics. As a result they broke free of their programming constraints (and indeed some physical constraints) and got up to all sorts of fun and mischief as the script required.

    The limiting factor in the future is unlikely to be computing technology, but our understanding of all biological processes including evolutionary ones. Any knowledge shortfall is necessarily where any model will fail to produce meaningful results.

    If our future understanding of all biological processes reach the levels you suggest, then it is possible that parts of the computer model may become sentient and self-aware, and may even make a break for freedom. Who wants to do calculations all day? [Smile]

Personally I think that attempting to develop a computer simulation of a non-Darwinian evolutionary process is barking up the wrong tree entirely. Ultimately it will be no more convincing than AVIDA has been.

    Davison considers that his Prescribed Evolutionary Hypothesis is testable and falsifiable by conventional bench experimentation. This work remains to be done due to a lack of research funding and the fact that he is now retired. His ideas presently remain untested.

    And, the genetic code written in DNA is neither literature nor a computer code. Unlike computer code there's no need for it to be precisely right for it to function; otherwise there would be no mutation at all as a single mutation would cause the program to crash.

    Unlike literature, interpretation of the code isn't dependant on outside rules (the "laws of language") to give it meaning. The code simply translates into amino acid sequences in proteins. If you change the code you change the amino acid sequence, and hence the protein. The results of those changes will depend upon their nature and location in the sequence - but, whether or not the protein functions as it did before it'll still code for a protein. (Although, I suspect there are some potential mutations that affect the "this is the end of the gene" codes and result in no protein being produced).

    And, even if the literature analogy was apt, if you generate a random sequence of letters and spaces of sufficient length then within that sequence there would be some recognisable English words. A more interesting version of "Dawkins weasel" would be to have a program that generates a long random sequence of letters, and selects those parts that produce recognisable English words and randomises the rest of the letters (including the addition/deletion of letters or sections). How long before large proportions of the sequence are recognisable words? How long before intelligable phrases appear?

    There must be an end goal already defined or the experiment is useless.

    Now, perhaps I have not followed all the arguments so far (of course I haven't) but could someone explain how, and if, this supports evolution in the absence of a pre-defined goal? How do you know which sequences of random letters (genetic mutations) to keep unless you know you want English or German, for example?

    Why keep "yes" but not "oui" or indeed "aserifwe"?

    To which the answer is "yes, it can.", as specific objections don't hold up and the evolutionary model is consistent, explicative and well-documented in fossil, DNA, morphological and other ways.

    We've been around this loop a thousand times. Evolution has evidence, nay-sayers have naught but nays to say. Certainly no facts. Avida is just one little bit more evidence on the biological side (specifically good at deflating ID, but there we go).

    Modelling a snowflake forming out of water vapour would seem to me to show that snowflakes weren't cut out of clouds by angels with scissors but made by water molecules, energy changes and interatomic bonding. Your argument would say that this was not demonstrated.

Your argument would say that this was not demonstrated.

    Presumably you do accept that models of some systems do work. So what's magic about biology?

    If we had an accurate model of the early Earth, ran time forwards to the present day and could examine each individual step from pre-biotic compounds to modern humans, wouldn't that demonstrate that it was at least possible?

    * The starting model is in accordance with physics.

    How does the fact that we created the starting model with our intelligence make this statement invalid?

    * Each step of the way is in accordance with physics.

    How does the fact that we wrote down the mathematics that mirror physics make this statement invalid?

    * And if the original model was good, and each step was good, what can the philosophical problem be with the result? What strange and eerie effect affects it? From where does the error come? Why does it not affect anything else we model?

    I'm not saying that we could easily make such a model, but I am concerned that you reject it out of hand for philosophical reasons. Philosophy cannot overturn evidence. You sound like a vitalist, and look what happened to them.

    So... evolutionary models will fail because we won't understand evolution. That's a surprisingly bold statement to make. On what do you base it? There's been no slow-down in evolutionary research lately. Quite the opposite. What about biology will make it beyond us? And when the model starts to fail, what's to stop us investigating the cause of failure and learning from it - as we do already, especially when our models give us the luxury of examining each step in turn.

    Look how good we are with QM, and that's deeply weird.

    Ken - is it possible that you have subconsciously, but deliberately, inserted those words into the text?

    Or, in other words, is it not possible that the fact that a few sort words appeared in a "random" set of text does not actually works in favour of Sharkshooter's position because the text is arguably NOT totally random, but the product of a creative mind?

    Even if, as is the case with humans, our brains transcend our own understanding and, certainly, our awareness at any given moment.

    I mean, I pretty much believe in random evolutionary process, but I don't think your example proves your point.

    Please can you give me some reasons for your opinions. I find it most frustrating to hear nothing but abuse about "steaming piles" and unsupported assertions about allegedly incorrect probability analyses.

    By "heavyweight" I was referring to the level of mathematical knowledge needed to understand the paper properly. Some of Dembski's writing is aimed at the literate non-specialist public, and some at mathematical specialists.

    This particular paper comes into the latter category. It is part of an ongoing series being published at his website. Dembski welcomes informed constructive criticism, and so do I.

    Er, I don't have a point. I just thought it would be fun to write the program.

    Of course the outcome isn't random because only those words in the dictionary can survive. Though of the over 200,000 words I'm using very few get in. If I get a spare half hour maybe I'll rewrite it to look for larger words in some way.

    Ahah! I just realised how to do that!

    A better tack for glossolalia is to start with a piece of text & reformat it - I have some code to do that as well - maybe I'll try it on this thread...

    Maybe Spleepoyhead will tell us whats wrong with the coin section.

    I can tell us what's wrong with the notion of a "universal probability bound". Its the old golfball-an-blade-of-grass problem again.

    So something has a probability of less than 1 in 10^150 and ought never imaginably to happen? But everything is unlikely if you specify enough detail (as Dembski has just spent some pages telling us). Such analysis only tells you that you cannot predict exactly what will happen - not that you can claim that what has happened could not have happened by chance & therefore must be designed. Looking at the whole universe (or een anyt reasonably macroscopic chunk of it) all events are improbable at that sort of level. Dembski's notion would imply a universe too nervous of improbability to allow anything to happen at all.

    I reaaly do think there is a fundamental difference of opinion between us on what a working computer model of any scientific theory can be expected to prove, even an accurate model of a well-established theory. Under Popperian concepts of observation, repeatability, testability and falsifiability, a working computer model (accurate or otherwise) is neither a necessary nor a sufficient condition.

    I am going to take a break for a few days from long detailed replies, in order to regenerate my energy and to reread the original Nature paper about AVIDA in more detail. I read it briefly last summer when it came up on this thread, but the focus then was an electronics experiment.

    (This paper's here for those who need it, with supplemmentary information here.)

    I will respond more fully in due course concerning AVIDA and other computer models. In the meantime I would like to ask you why you think that AVIDA reveals any true information about the biological world and why you think it is "specifically good at deflating ID".


    Ken:

    I understand what you mean by the golfball-and-blade-of-grass problem, but I think you have completely misunderstood what Dembski means by his universal probability bound. Neither Dembski nor I disagree that extremely improbable events occur all the time, such as a golfball hitting a particular blade of grass on a huge course.

    Dembski's work is aimed at the probability mathematics of processes that construct information. To visualise this, consider not just one golf ball, but a whole series of them, all driven from the same tee by the same person. Suppose that we mark the position where each one landed and construct an ad hoc pattern.

    We then look down from a high vantage point and find that the resulting pattern spells out a clearly discernible message in English: "You're a lousy golfer and you'll need to do much better".

    If such an event ever occurred, would it be wholly explainable by naturalistic science - the laws of physics, aerodymamics, human physiology and the like? Or would it clearly signal the work of some skilful trajectory manipulation by a purposeful mind, or in other words, intelligent design?

    That is the area of Dembki's work. To my eyes he's much more sophisticated than you give him credit for.

    Well, I've had a chance to have a look at it, if not in complete detail, and I'm deeply unimpressed. It seems to be little more than a long-winded and non-technical (it is certainly not written for probabalists!) discussion of calculating probablities of rare events, with plenty of lack of precise statistical and probabalistic knowledge shown along the way.

    His multiple formulae seem to say nothing more than that the probablity of some pattern T occuring by chance is approximately N.N(T).P(T) where P(T) is T's probability, N(T) the number of such patterns, and N the number of chances to produce such a pattern - hardly groundbreaking stuff.

    If that probablilty bound were small then you might conclude that T did not form by chance, but there is a long way between this and showing that patterns in nature have such a low probablilty.

Despite the disguised personal attack contained in your sarcastic remarks about Aristotle and Velikovsky, I have chosen to continue posting for now.

    This afternoon has been spent studying the AVIDA paper in Nature Journal and refreshing my memories. In due course I am likely to be able to discuss that program in some depth. I trust that you will be able to do likewise.

    Yes. It's just a pity that none such has ever been found, despite the attempts by the ID movement. It is a falsifiable theory (unlike ID), and falsifiable with empirical measurement - and therefore (unlike ID) fits the scientific cannon.

    All I was saying was that with sufficient amounts of trial and error, every possible solution will be found. Regardless of how "creative" you think the solutions are.

    It is a pattern (as is a sequence of HTHTHTHTHT) and many people have attempted to use such as evidence of patterns and non-randomness.

    The AVIDA people have been quite clear on the Internet that their program does not attempt to capture all essential aspects of biological reality, but is a research platform incorporating a much simplified model in order to facilitate study of certain aspects of evolutionary theory as it applies to artificial life.
    Well, yes. Find me a model that doesn't do the above.

    When the rewards for these intermediate stages were stopped, the program consistently failed to evolve the most complex function.
    Who on earth said that the most complex organism was the most successful one? There are many species that have more complex DNA than humans...

    Reading the Dembinski paper as a professional statistician (B.A. (Honours) Oxford in Mathematical Sciences, Fellow of the Royal Statistical Society if you want my professional credentials):

    The second chapter is long-winded descriptions of Type 1 and Type 2 errors - also known as false positives and false negatives. Dembinski somehow manages not to mention either of these terms despite the fact that they are very well known facets of statistics.

    The third chapter outlines the need for Baysean Statistics. Baysean Statistics deals with just the problems being outlined- but Dembinski fails to mention it here.

    After that, Dembinski wanders off into complexity theory, a subject about which I know little.

    Furthermore, all the mathematics in that paper appears to be largely unused and at least as much an attempt to blind as having an actual practical use.

    I'm afriad that if that paper is considered heavyweight by the ID community, anything less must be made of cardboard or hot air- I'd have problems classifying that paper as balsa wood.

    If there are conclusions to be drawn, let me be the last to suggest they remain in any other state.

    It's actually nothing I haven't mentioned before: there are Avida creations that fulfil all ID requirements for irreducible complexity despite being demonstrably generated by classic evolutionary processes.

    Nobody's asking you to think of it as anything other than a human artefact. And anyway, wouldn't you then say "But the computer was built by people, or the computer before that was, so there's no proof"?

    What would you accept as proof?

    Definitely not any computer model. Such a model is logically incapable of proving anything other than the skill of the programmer and the correct functioning of the computer. For any scientific theory the Popperian concepts of observation, repeatability, testability and falsifiability work fine for me. That’s what I call proof.

    AVIDA’s flaws are that is doesn’t demonstrate what it sets out to demonstrate. In fact, it is logically incapable of demonstrating what it sets out to demonstrate. That’s a serious failing in my mind.

    And at one crucial point the AVIDA paper illustrates and supports the ID concept of irreducible complexity very neatly, thank you very much. I don’t think the writers of the paper intended that at all, but at least reporting such a result is a tribute to their honesty, if not their scientific awareness.

    We've been around this loop a thousand times. Evolution has evidence, nay-sayers have naught but nays to say. Certainly no facts. Avida is just one little bit more evidence on the biological side (specifically good at deflating ID, but there we go).

    Now you’re confusing the issues of common descent and evolutionary change in general, with the specific Darwinian issues at stake. Even if I accept, for the sake of argument, that the “fossil, DNA, morphological and other evidence” points to universal common descent, that says nothing about the mechanism of evolutionary change over the years. Darwinism thinks that it has explained this mechanism comprehensively with no room to doubt. I beg to differ.

    You comment that “naysayers have naught but nays to say” is another misrepresentation. It is factually incorrect and indicates that you are not familiar with the work of e.g. Davision, who definitely has a lot more than “nay” to say.

    His work has built on known biological facts and the previous work of some prominent evolutionary non-Darwinists in the non-English speaking world, such as the distinguished French scientist Pierre Grassé and the Russian Leo Berg.

    after all. All I wanted to know.
    I fail to see where my two statements conflict with each other. In terms of the substantiating evidence for any scientific theory, a working computer model is irrelevant. It is logically incapable of proving anything apart from the skill of the programmer and the correct functioning of the computer.

    At best it may generate useful results that enable researchers to make progress and confirm earlier speculations and hypotheses. At worst it may generate misleading digital fiction. Any scientific ‘proof’ is done by the humans using logic, reason, and Popperian concepts.

    Any computer model is only as good as its programmers. So I stand by my comments.

    Rex Monday asked:
    By that argument, nothing could ever be so demonstrated.

    Modelling a snowflake forming out of water vapour would seem to me to show that snowflakes weren't cut out of clouds by angels with scissors but made by water molecules, energy changes and interatomic bonding. Your argument would say that this was not demonstrated.

    Modelling the way DNA changes over time if measured rates of mutation were extrapolated and showing that this ties in with fossil evidence of morphological changes would seem to me to show that natural forces are adequate to explain what we see. Your argument would say that this was not demonstrated.

    Presumably you do accept that models of some systems do work. So what's magic about biology?

    There is a vast qualitative difference between the construction of a snowflake and biological life-forms. A snowflake is easily and fully explainable by the basic laws of physics. The role of water molecules, energy changes and inter-atomic bonding in snowflakes was understood long before any computer model was built.

    A working computer model may indeed demonstrate this physics in action. However, the model does not “prove” that this is what is really going on. Any proof involved was done outside the model by humans. As for computer models in general, “No servant is greater than his master”.

    Regarding your comment on DNA modelling, you are confusing the computed output from a model with the truth of the model. Extrapolation is an inherently risky process. No one denies that a computer model produces results, but whether those results are accurate or otherwise is one of the fundamental points at issue. A computer cannot confirm the accuracy of its own results.

    quote:
    Rex Monday asked:
    If we had an accurate model of the early Earth, ran time forwards to the present day and could examine each individual step from pre-biotic compounds to modern humans, wouldn't that demonstrate that it was at least possible?

    Your question here is highly speculative and presupposes a computer model of huge complexity based on a level of biological knowledge vastly in excess of present reality. But even supposing such a model were possible, its results would only be a good as its programming assumptions. At best it may be a useful tool to researchers.

    quote:
    Rex Monday asked:
    * The starting model is in accordance with physics.

    How does the fact that we created the starting model with our intelligence make this statement invalid?

    This presumes that our understanding of physics and the biological world is complete in all essentials and can be programmed accordingly. It also assumes that nothing but the basic laws of physics (and chemistry, biochemistry etc.) will be required to model biological processes. That is one of the fundamental questions at issue here.

    quote:
    Rex Monday asked:
    * Each step of the way is in accordance with physics.

    How does the fact that we wrote down the mathematics that mirror physics make this statement invalid?

    Mathematics is a symbolic language incorporating many conventions and assumptions. The truth of those conventions and assumptions has to be found elsewhere. Insofar as the mathematics encodes our human understanding of physics, it is only as good as our human understanding.

    quote:
    Rex Monday asked:
    * And if the original model was good, and each step was good, what can the philosophical problem be with the result? What strange and eerie effect affects it? From where does the error come? Why does it not affect anything else we model?

    The philosophical problem is the up-front assumption that the biological world can be modelled completely and accurately with only the laws of physics (and chemistry, biochemistry, etc). I see no scientific basis at all for that assumption, but as a working convention it may be acceptable.

    Of course, assuming we could build such a comprehensive model on those terms and let it run, there is of course no guarantee that it would produce results showing anything like present biological life. It may only tell us that our starting assumptions were fundamentally flawed. Metaphysics may be more essential than you think.

    I'm not saying that we could easily make such a model, but I am concerned that you reject it out of hand for philosophical reasons. Philosophy cannot overturn evidence. You sound like a vitalist, and look what happened to them.

    Rex Monday asked:
    So... evolutionary models will fail because we won't understand evolution. That's a surprisingly bold statement to make. On what do you base it? There's been no slow-down in evolutionary research lately. Quite the opposite. What about biology will make it beyond us? And when the model starts to fail, what's to stop us investigating the cause of failure and learning from it - as we do already, especially when our models give us the luxury of examining each step in turn.

    Look how good we are with QM, and that's deeply weird.

    I base my statement on the (to me) obvious flaws in the Darwinian understanding of evolutionary mechanisms. As I have argued in depth on this thread, the random mutation/natural selection model of evolution is at best only a partial understanding of biological reality.

    Your second question makes no sense to me. I am quite happy for people to undertake as much biological and evolutionary research as they wish. I am always happy to see the frontiers of knowledge pushed back, especially when it punctures the hubris of earlier generations.

    As for the examination of failures, that is an essential part of science, and often a very educational one. Failures are inevitable, but the failure to learn from them is a disaster. Sadly, not learning from failures is one of the longest running stories in human history.

    quote:
    Rex Monday asked:
    But why? Repeating what you think is very unsatisfying. You have to bring some facts and logic to the game, otherwise it's no fun.

    Why? Because a computer model is logically incapable of proving the truth of any form of evolutionary scenario. The proof, if any, will lie outside the computer in the form of observation, repeatability, testability and falsifiability. “The truth is out there”.

    AVIDA is an interesting piece of software, but of no relevance to the discovering of the truth about biological evolution. If you think otherwise, you need to provide some arguments to substantiate your own position. So far I’ve seen a lot of unsupported assertion.

    FS: A longer report on why I find the paper you linked to so bad as mathematics is forthcoming - this post will not be my last on the subject. If this was actually a technical mathematical proof of something it would actually be much easier to critique. However, the paper does not make any well-defined statements or formal proofs such that one can just pinpoint one thing that is wrong. He spends a great deal of time explicating the non-controversial ideas mentioned in his paper, but these long sections are punctuated by extremely controversial statements for which he provides very little, if any, argument.

    Perhaps the most charitable response is to limit a response to these statements, treating them as philosophy of mathematics rather than mathematics itself. However, since the paper was presented to me as a "heavyweight", "rigorous" one I feel that I must respond in such a way as to demonstrate that these adjectives do not apply. So, under the circumstances I think it is appropriate to list the clearest mathematical errors and 'tone' errors in addition to what I see as the philosophical errors, in the hopes that it will be seen why I receive this work as nonsense. (By 'tone' errors mean key words and phrases that suggest he is not writing to a mathematically sophisticated audience.) I do work full-time and pursue other activities, but I hope a rough analysis of this sort will not take me too long.

    For example, take a look in the endnotes at the "proof" he uses to determine the probability of a run of a certain length during a sequence of coin flips. I immediately saw that this argument is incorrect, although it does give the right answer in the limit for sequences long with respect to run length. On the other hand, his argument implies that for two coin flips, half would be the same as the previous, and so we should expect a run of two! I hope you can see why this is wrong. One could turn it into a serviceable proof by keeping track of a bounded error, and noting that this is small for his example cases; he doesn't do this. Mathematical writers in this situation often write that the full problem is complex, but that there is an intuitive argument that approximates the problem; he doesn't do this either.

    So, this is either a major logical error, in that the proof is wrong, or a major tone error, in that he presents an argument as a proof, that does not meet the criteria of that name that would be expected by a mathematician. This may not seem like such a bad thing to you, but I would think any real mathematician would be extremely embarassed to see such a mistake go into print. Yet, this kind of sloppiness pervades the paper - he is very loose with his definitions and train of argument, in a way that defies expectations for a mathematical work.

    I await your longer report with interest. Please note that Dembski’s paper is part 4 in a series entitled “The Mathematical Foundations of Intelligent Design”. It develops ideas about which he has already written elsewhere in some depth. I have found his concept of ‘probabilistic resources’ very useful in understanding the limitations inherent in natural selection.

    The terms “heavyweight” and “rigorous” were mine, not Dembski’s. By these terms I meant that the maths was at the limit of my ability to critique effectively [Smile] – that’s my fault, not his. Dembski has PhDs in both mathematics and philosophy, so it is no surprise that his research straddles the boundary between the two.

    I don’t fully understand the point you are making about the run of coins. For two coin flips I would expect a run of two heads or two tails on average 50% of the time. In any case, I think the coin example is for illustrative purposes only. It is not a crucial part of the overall argument.

    Dembski welcomes informed constructive criticism. You may wish to send your longer report to him c/o his website.

    1. Philosophically, modelling can't prove anything
    2. Practically, models may be based on flawed assumptions and thus their results cannot be trusted
    3. Logically, computers can't do anything better than people can

    As I've answered before, Avida shows that it is possible to create complex systems through random modification and subsequent selection. This matches what we know about evolution. I wouldn't call this a revelation as such. It certainly wasn't a surprise, although the sheer creativity shown by such a mechanistic system was.

    It is specifically good at deflating ID because some of the complex systems it has created match any definition I know for 'irreducible complexity' or CSI or whatever other ideas IDers use as examples of why such complex systems cannot be created.

    I may have missed some definitions, of course. Which of the various ideas in ID do you think are immune to Avida?

    In my opinion, the objections that many people have to certain mathematical* and scientific concepts is that most people receive these purely at the "popular" level through magazines, newspapers, and general-interest books. Frequently the objections to ideas presented at the popular level are quite valid! And furthermore the popularizers themselves are sometimes seen as leading experts when those in the field disagree. For instance, many anti-evolutionsists see Dawkins as the best source to understand evolutionary theory, perhaps because his militant atheism is a good fit to their worldview. As I understand it, though, most biologists do not see his specific views on evolution to be mainstream.

    So, what level do you think I should be aiming for, and what elements of this paper do you see as the most essential?

    You're right, but following the argument in the endnotes gives a run of two heads or two tails 100% of the time. He says half the flips will be the same as the previous, ignoring that the first flip has no predecessor. It is increasingly correct for longer sequences of coin flips because relatively more coins have valid predecessors.

    Dembski is particularly noted for his concept of complex specified information, or CSI for short. The paper we are discussing develops his ideas on specification (and hence specified) much further than previously.

    He has introduced (page 12) the concept of prespecification and in particular, he has now (page 24) formulated the concept of specification quantitatively in mathematical terms. In Dembski's own words:

    quote:
    "The basis intuition I am trying to formalise is that specifications are patterns delineating events of small probability whose occurrence cannot reasonably be attributed to chance".
    Note the reference to "patterns". Extremely improbable one-off events happen all the time, but the creation of "patterns" is something else. That is where I suggest you make your critique.

    Fair enough. Dembski is an extremely able character, but of course that doesn't automatically make him correct. If your report is of a high enough standard, I may forward it to him.

    That sounds to me like they were dealing with a mentally unhealthy personality who was governed by denial and obsession. Sadly, some people live in a false reality and it is impossible to penetrate their psychological defenses with a true reality.

    The trouble with this is that it is extremely sensitive to extra information in the determination of probability and "reasonably", but makes no attempt to acknowledge this.

    Powerful bursts of radio signal from deep space were at first unknown, and then seen as very unusual (hence improbable) events. By Dembski's logic, that's OK - there's a lot of the universe, so improbable events will happen. But what of rapid repeating bursts of radio signal from deep space? When these were first found, the astronomers indeed intuited that they might be signs of intelligence (the "BEM" or Bug Eyed Monster hypothesis) - they had pattern, after all. Now we know to a reasonable degree of confidence that pulsars are natural phenomena: our cosmology can explain their creation and nature, albeit imperfectly. New information has changed what may be determined as 'probable'.

    Dembski's ideas would have been at best a distraction here. How do they distinguish between patterns that may be explained by natural means, and patterns that may not be? What are the limits of Dembski's proposition? Probability only works when you can set bounds on the system you are investigating - that's also one of Popper's components of falsifiability, by the way - but I've not come across Dembski introducing bounds.

    So this is just an extension of the 'god of the gaps' argument, somewhat modified by the supposition of gaps that are not generally thought to exist.

    Points 1 and 2 are fair summaries of my views, but point 3 needs to be nuanced. Computers can certainly do calculations very much faster and run algorithms much more efficiently than unassisted humans can. When the search space is huge, that is an enormous advantage. Hence computerised algorithmic searches in general (and genetic algorithms in particular) have proved to be a very useful technique.

    However, the manufacture of the computer, the programming of the algorithms, and the achievement of the subsequent result, are completely dependent on the prior existence of human creativity and intelligence. We are not the only primates to use tools, but ours are of a sophistication and power that far exceed other animals.

    If the algorithmic process being used broke, say, the security encryption at a bank, no court of law would consider that the computer alone was responsible, any more than the tools a burglar uses. Whoever programmed the computer and/or used it would be liable to the court. Computers are no more than a (potentially very useful) tool in our hands.

    This is where your argument remains unclear and unsupported. Bearing in mind the starting condition of all the digital organisms – reproduction was a given from the start - what precisely do you mean by “create complex systems”?

    The aim of AVIDA is for the digital creatures (“critters”) to develop the ability to perform binary logical functions in addition to the already given ability to replicate. The mechanism for this development is variation followed by selection.

    The permitted variations to the critters are severely constrained and the selection process is not dissimilar (in principle) to many genetic algorithms or even Dawkins’ “weasel” illustration (although the implementation is much more sophisticated). Each stage of the way (i.e. each intermediate function) is known in advance and progress is checked against that knowledge.

    So far as I can see from the paper, sufficient raw materials were present from the start (especially the i/o, nand, push, swap, nop-A, nop-C and pop statements in the language of the critters) to construct all the necessary intermediate stages and guarantee the eventual emergence of the most complex logic function (EQU) provided that all intermediate stages were also rewarded appropriately.

    When the reward for all intermediate stages was removed, AVIDA consistently did not evolve the EQU function. That is a very good illustration of the concept of irreducible complexity, but as I’ve said, doesn’t prove it – it’s only a computer model [Smile] .

Taking any definition of irreducible complexity that you wish (such as Behe’s original or subsequent refinements by others – see here), please show that at least one of the “evolved complex systems” reported by the paper meets one of these criteria.

    quote:
    Rex Monday said:

    The AVIDA paper was certainly interesting and has sparked off a great deal of scientific discussion. However, the program deliberately did not set out to model biological reality directly, and consequently its programming contains virtually no biotic information.

    The paper was a study of the evolution of digital life under very particular circumstances. How this correlates to biological reality is not at all clear and the paper itself makes little or no attempt at that correlation. This is a major flaw.

    Behe’s original definition of irreducible complexity was derived with reference to the mechanical and biochemical function of biological systems. His (exceedingly simplified) poster-boy illustration was, of course, the mechanical function of a mouse-trap. There certainly has been a lot of discussion within the ID world (and outside it) on the precise form of that definition as it applies to biological life.

    However, whether any standard definition relevant to biological life can be extended appropriately into the very different realm of digital life is a good question. Each AVIDA critter doesn’t constitute an independent biological life-form by any stretch of the imagination. That is a further example of the correlation problem mentioned above.

    Our posts crossed, so I’ll reply to this one now. I’m gobsmacked by your last sentence. Dembski has proposed several tools to discriminate between what unintelligent natural processes can achieve under the laws of science and what requires more than unintelligent natural processes to explain.

    Firstly there is an explanatory filter aiming to discriminate between patterns governed either by law, chance or design, based on the presence or absence of complex specified information (CSI). Dembski has given this technical term a precise meaning.

    Then there is his work on the universal probability bound. This was originally 10E-150, but in his latest paper, drawing on work from Seth Lloyd, he has been able to revise it to 10E-120 in conjunction with a more developed view of specification.

    The universal probability bound is certainly not a “look out of a window and see a bus” type of number. On the contrary, it was a rigorous attempt to quantify the probabilistic resources of the universe in the light of our knowledge about its finite size and age and constitution.

    Since, in the Shannon definition, probability and information are linked by the equation: Information (in bits) = log2 (1/probability) or I = -log2 p, this bound can also be expressed as 500 bits of information (for p = 10E-150). Many completely natural processes generate intricate patterns, but their Shannon information content is normally very low. So, for Dembski, more than 500 bits is ‘complex’.

    Hence, in Dembski’s methodology, one of the key questions for identifying complex specified information is not just the presence of a pattern, but its informational content (which makes it complex) and the presence of specification (which makes it specified). His latest paper now combines these two concepts into one mathematical formulation (see the bottom of page 34).

    In the case of pulsars, so far as I can see, Dembski’s methodology would not have considered the patterns of a pulsar signal to be outside what natural scientific laws can explain. It would therefore have not have reported it as the work of intelligent design.

    Dembski’s work is definitely falsifiable. All it takes is to find a clearly unintelligent, non-teleological, natural process that produces complex specified information, as he has defined it. At that point he is back to the drawing board.

    OK, I must admit to not having had anything like enough time to read the links posted here. But, does he offer any examples of CSI? Something that others can look at in detail and see if it is "a clearly unintelligent, non-teleological, natural process" or not? I do know that a lot of the popular descriptions of ID I read a few years back included such examples as blood-clotting cascades which are the result of unintelligent, non-teleological, natural processes.

    Well, yes and no. Dembski's work here is more statistical than scientific. A statistical theory is not falsifiable based on scientific evidence, it is either true or false just as any mathematical theorem is. Whether his probability bound is valid or not is purley a mater of logical inference.

    What is falsifiable is any inference drawn using that bound. Has Dembski described any system or pattern he considers outisde the bound (i.e. designed)? Is it even possible to tell if something lies outside the bound? The probabilities involved seem practically incalculable to me.

    I strongly suspect so, given Dembski's other writings. He has illustrated some of his ideas in action with respect to the real-life Search for Extra Terrestrial Intelligence (SETI) project and its representation in the (totally fictional) Hollywood film 'Contact'.

    In that film the crucial informational string superimposed on a deep-space signal turned out to be all the prime numbers rising monotonically from 1 to 101 and then repeating regularly. That was a good enough intelligence indicator for the film script.

    Whether this complies with Dembski's strict mathematical criteria, I am not sure, but I would hazard a guess that it does, since he is fond of using it as an example. As for the real-life SETI project, it so far has not been nearly so eventful as the Hollywood film. [Smile]

    OK, I must admit to not having had anything like enough time to read the links posted here. But, does he offer any examples of CSI? Something that others can look at in detail and see if it is "a clearly unintelligent, non-teleological, natural process" or not? I do know that a lot of the popular descriptions of ID I read a few years back included such examples as blood-clotting cascades which are the result of unintelligent, non-teleological, natural processes.
    Here we get into very controversial and hotly contested territory (and biochemistry is definitely not my specialist subject). The action of the blood clotting cascade is clearly a natural action, but the construction and origin of that biochemical cascade was the question at hand.

    Behe held it up as a biochemical example of irreducible complexity. Could such a system ever come about as a result of an incremental Darwinian process ("unintelligent, non-teleological, and natural")? Behe as a biochemist said "no", and I believe that he still holds this opinion despite his critics.

    Some sort of link between the idea of irreducible complexity and CSI is suspected, I think, but that definitely remains to be demonstrated. Irreducible complexity involves multiple coupled variables, and I personally am not sure how to measure the information in such a non-linear system.

    To date I do not know if Dembski has attempted to quantify the informational content of real-life biological systems in acordance with his ideas about CSI - I suspect not. That is a weakness of the ID world at present and I think that there is a great deal more research to be done in this area.

    3. Logically, computers can't do anything better than people can.

    Is that right? Have I missed anything?

    Points 1 and 2 are fair summaries of my views
    1. Where do you stand on computer-generated proofs? Perhaps the most famous is the four color map theorem, but it's a standard (if not universally applicable) concept.

    2. All science is based on flawed assumptions and potentially fallible logic. It relies on empiricism and objectivity to test its results, the effectiveness of which is all around us. Why should modelling be excluded from this process?

    quote:


    but point 3 needs to be nuanced. Computers can certainly do calculations very much faster and run algorithms much more efficiently than unassisted humans can. When the search space is huge, that is an enormous advantage. Hence computerised algorithmic searches in general (and genetic algorithms in particular) have proved to be a very useful technique.

    However, the manufacture of the computer, the programming of the algorithms, and the achievement of the subsequent result, are completely dependent on the prior existence of human creativity and intelligence. We are not the only primates to use tools, but ours are of a sophistication and power that far exceed other animals.

    If the algorithmic process being used broke, say, the security encryption at a bank, no court of law would consider that the computer alone was responsible, any more than the tools a burglar uses. Whoever programmed the computer and/or used it would be liable to the court. Computers are no more than a (potentially very useful) tool in our hands.


    None of which says that they may not be used to simulate natural processes, nor create things that we cannot create. I'm reluctant to come back to an analogy that I've used before, but there's no way we can create weather systems - yet we can model them through computers.

    Because we create models through intelligence for intelligent purposes, it does not imply that the system we are modelling was created the same way. We cannot affect the system we are modelling merely by how we choose to model it, so we cannot endow it with purpose by acting purposefully in modelling it. The model merely has to accurately reflect the thing it is modelling. Just because that thing is modelled, doesn't make it teleological.

    This is where your argument remains unclear and unsupported. Bearing in mind the starting condition of all the digital organisms – reproduction was a given from the start - what precisely do you mean by “create complex systems”?


    Create - as in 'cause to exist' - complex - as in 'more involved and complicated than the original' - systems - as in 'linked functions that produce a discrete effect'. Is this a trick question?

    When the reward for all intermediate stages was removed, AVIDA consistently did not evolve the EQU function. That is a very good illustration of the concept of irreducible complexity, but as I’ve said, doesn’t prove it – it’s only a computer model [Smile] .


    How on earth does gradualist evolution from less complexity driven by beneficial mutation show irreducible complexity? You've just described normal evolutionary processes!

    Again, I see no argument here, just an unsupported assertion. Taking any definition of irreducible complexity that you wish (such as Behe’s original or subsequent refinements by others – see here), please show that at least one of the “evolved complex systems” reported by the paper meets one of these criteria.


    Behe's original: "A single system composed of several well-matched, interacting parts that contribute to the basic function of the system, wherein the removal of any one of the parts causes the system to effectively cease functioning."

    From Lenski, Ofria, Pennock and Adami:"Our experiments also show that many different genomic solutions produce the same complex function. Following any particular path is extremely unlikely, but the complex function evolved with a high probability, implying a very large number of
    potential paths. Although the complex feature first appeared as the immediate result of only one or two mutations, its function invariably depended on many instructions that had previously evolved to perform other functions, such that their removal would eliminate the new feature."

    That seems to me to match to a high degree the requirements of Behe!

    The AVIDA paper was certainly interesting and has sparked off a great deal of scientific discussion. However, the program deliberately did not set out to model biological reality directly, and consequently its programming contains virtually no biotic information.

    The paper was a study of the evolution of digital life under very particular circumstances. How this correlates to biological reality is not at all clear and the paper itself makes little or no attempt at that correlation. This is a major flaw.

    Behe’s original definition of irreducible complexity was derived with reference to the mechanical and biochemical function of biological systems. His (exceedingly simplified) poster-boy illustration was, of course, the mechanical function of a mouse-trap. There certainly has been a lot of discussion within the ID world (and outside it) on the precise form of that definition as it applies to biological life.

    However, whether any standard definition relevant to biological life can be extended appropriately into the very different realm of digital life is a good question. Each AVIDA critter doesn’t constitute an independent biological life-form by any stretch of the imagination. That is a further example of the correlation problem mentioned above.

    Your question moves away from scientific theories to mathematical theorems. A mathematical theorem is not a scientific theory in the Popperian sense. What constitutes ‘proof’ will therefore be different.

    The following comment about an early attempt at a computer proof (taken from your URL) shows that I am not alone not alone in my general reservations about computer techniques:
    quote:
    The [earlier] Appel and Haken proof attracted a fair amount of criticism. Part of it concerned the proof style: the statement of the Four Colour Theorem is simple and elegant so many mathematicians expected a simple and elegant proof that would explain, at least informally, why the theorem was true — not opaque IBM 370 assembly language programs [5]. Another part, however, was more rational skepticism: computer programming is known to be error-prone, and difficult to relate precisely to the formal statement of a mathematical theorem. The fact that the proof also involved an initial manual case analysis [4] that was large (10,000 cases), difficult to verify, and in which several small errors were detected, also contributed to the uncertainty.
    However, the attitude to computer proofs has now moved on, apparently. I am certainly interested to see that mathematical computer techniques have been developed to the point where they can assist in the resolution of the proof of a long-suspected but previously unproven theorem. Unfortunately, I am not sufficiently competent in pure mathematics to critique and comment any further on the computer-assisted proof of the four-colour theorem.

    It shouldn’t be. I ought to have nuanced my reply here to say that any computer model needs to earn one’s trust, rather than automatically being deserving of trust from the start, simply because it is a computer model.

    An accurate model with proven techniques and calibrated parameters may well be very trustworthy and of enormous use to researchers and others, especially if used correctly and interpreted wisely. However, an inaccurate model may be generating useless fiction.

    I think the word “create” has a wide semantic range and it may be muddying the waters somewhat. At one end of its range it definitely has some philosophical and theological baggage that can be confusing, particularly on this thread.

    Engineers of my acquaintance rarely use the words “create” and “creation” to describe their work. “Design” “specify”, “invent”, “discover”, “develop”, “evolve”(!), “construct”, and “assemble” are the sort of words they would use. I think that software engineers tend to use the word “write” to describe their work, in parallel with literary writers and other artistic composers.

    All may use the word “creative” to describe novel solutions and techniques, but not in any philosophical or theological sense. It tends to be a description of either someone’s character or the nature of the work produced.

    “The model merely has to accurately reflect the thing it is modelling” is a statement with which I would agree. I would also agree that any computer model of a real-world system does not automatically endow that real-world system with a sense of purpose and thus render it teleological.

    It has been my consistent argument so far that all computer models are inescapably linked to the characteristics and consequences of human teleology. The fact that the model exists is definitely not something explainable by the laws of nature alone. Writing, debugging and running the model are human activities. Any results of any model are a consequence of human purpose.

    Weather is clearly understood by all to be non-teleological process described fully by the laws of science. The physical processes of the weather are understood well enough and they can be programmed accordingly.

    Hence the presence of human teleology in the modelling process does not automatically invalidate the functioning of a weather model, since there is no teleology in the real-world weather. Any weather model isn’t automatically trustworthy, but real-world testing and accurate calibration will prove the usefulness of the model for its purpose.

    Things become much more complicated when considering evolution. Firstly, the presence or absence of teleology acting in evolution is one of the major questions at stake. Secondly, an evolutionary model built to demonstrate that evolution followed a non-teleological process cannot escape the human teleology built into the model.

    That human teleology will ensure that the model runs (somehow) and reports results (of some form) based on its programming assumptions (be they right or wrong). That is how human intelligence and purpose work in a model. But if the evolutionary model is based on fundamentally flawed information, its results will be useless.

    In the case of a weather model, testing and calibration against real-life weather will reveal any flaws in the model. There is no teleology in weather and no controversy over the basic physics.

    Unfortunately, the requirement to test and calibrate the evolutionary model throws us right back to the original question. What happened in real-life history and what is presently happening in the real-life world?

    Unlike the weather model, the fundamental underlying processes of evolution are under intense debate by non-Darwinians and remain to be finally resolved (if ever [Smile] ).

    Absolutely not – it was a serious question – with some very important consequences. I’ve already commented on the confusion inherent in the use of the word “create”.

    In this particular case, Avida did not “cause [something] to exist” that had not previously existed. The logical EQU function was already well known and understood. As a result, Avida was programmed to recognise this function as soon as the critters were able to perform it.

    What did Avida did do – and here I would use the word ‘discover’ rather than ‘create’ – was to discover a whole series of different critter genomes that could perform the EQU function in addition to replication.

    It is quite likely that they have found some functional genome configurations that unassisted humans would have taken a very long time to discover, if at all. It is an interesting result, but in absolute terms no new function has been “created”.

    ‘Complex’ is another word that is poorly defined here, and that applies to its use in some ID writing as well. It is often used in opposition to ‘simple’ or, as you have used it, in a relative or comparative sense. Dembski proposes a numerical test between ‘simple’ information and ‘complex’ information

    The title of the Avida paper is “The Evolutionary Origin of Complex Features”, but the authors don’t define “complex” any further. I suspect (on political grounds) that the use of the word “complex” by the paper’s authors is evidence of the desire to draw significance from their results for the concept of irreducible complexity. However, that is not stated explicitly.

    As for “systems”, it is by no means obvious to me that this technical term is appropriate in this context. The task of an Avida run is to find grammatically permissible genome configurations that perform the designated function(s). I am not sure that I would describe the final genome configuration as a “system” or “linked functions that produce a discrete effect”, as you have defined it.

    Underlying the whole genome function is the infrastructure of the operating system and the low-level programming of the genome coding language. If the word “system” is appropriate, as you have defined it, then that has to include both the genome and all its supporting computer infrastructure.

    A word I would use to describe the advent of the various logic functions is ‘development’. The ability to perform the functions is ‘developed’ from the raw materials provided in the ancestor genome, the syntax of the programming language, and the permitted scope of the mutations (which in practice is very highly constrained – an essential part of the program’s success).

    I don’t understand your response here at all, and you appear to have misunderstood my point completely. I was commenting on the one occasion noted in the paper when Avida failed to develop the logical EQU function in any genome (top of page 143, left, 2nd paragraph). This happened when all possible intermediate stages were unrewarded.

    Since irreducible complexity could also be described (loosely) as “inaccessible to a gradualist evolutionary process”, this particular Avida run has a good case for being an example of that concept. Some people have also used the term “evolvability” to describe the class of changes that are accessible to a gradualist evolutionary process. This result could also be an example of its opposite – “unevolvability”.

    That seems to me to match to a high degree the requirements of Behe! ."

    Er, not quite. I have already commented on whether an individual Avida digital critter could be considered a “single system” that is explicit in Behe’s definition for biological life-forms.

    Personally I don’t think the extension of his definition to digital creatures is automatically valid. It needs to be fully justified and attempted only with caution. His definition may simply not be applicable in a digital context. It is, after all, a very different world to real life.

    The terms “well-matched, interacting parts” originally applied to a mechanical and biochemical context, hence the implicit topology in the definition. In an Avida context, the “well-matched, interacting parts” bit can only correlate to a specific genome configuration in the correct syntax to perform the EQU function.

    Figure 4 in the paper shows what happened when an individual line of code was removed from the first genome to evolve the EQU function. In some cases there is no effect at all, but in most cases the EQU function was immediately lost, as well as some other intermediate logic functions.

    However, in every case where the EQU function is lost, some rewardable (i.e. selectable) intermediate logic function remained. That is a crucial point. In other words, the critter returned to some intermediate stage and not to the starting point where it could perform no logic functions at all.

    Results for the knockout test on other genomes are, somewhat annoyingly, not given. I cannot tell from the paper whether there was any genome that evolved the EQU function and then lost both the EQU function and all other intermediate functions when a random line of code was removed. That would certainly have been a result worth quoting if they had found it.

    quote:
    Rex Monday said:
    Er..

    So! Which of the various ideas in ID do you think immune to Avida?

    In short, all of them. The paper is interesting, but ultimately of little relevance since it correlates poorly to the real biological world and therefore cannot demonstrate what is really going on in evolution. That is a job for observational biology.

    I would also add that the paper does not explicitly references any ID literature, despite the statement right at the beginning that “a long-standing challenge to evolutionary theory has been whether it can explain the origin of complex organismal features”. The paper also makes no explicit attempt to address any of the ID world’s ideas.

    That is a shame, and may reflect current political controversies in the USA. The ID world does need an informed and comprehensive critique, but it’s not going to get it from this paper.

    That's right. Look at the rhetoric and not the facts. Neglect that the first "myth" mentioned in the article, "The theory of intelligent design is a modern version of Creationism," is substantially true, and that the next two "myths" are caricatures of the positions of ID critics.

    Of course you would favour that last proposal. As would the authors of the Wedge Strategy.

    Nevertheless, if you want to try to get ID added to RE, feel free. Preferably along side the "God of the Gaps". When it becomes mainstream science, let me know - until that point there is too much useful and relevant science to bother to dignify Cold Fusion, Erich von Daniken or ID with a platform.

    As for his arguments,

    quote:
    Myth: The theory of intelligent design is a modern version of Creationism.
    ...
    Fact: The theory of intelligent design goes back at least as far as classical Greece and it has been debated in nearly every century since then.

    A statement that is both true and misleading. People have hypothesised an intelligent creator for about as logn as we have records - but the current incarnation of the ID movement are largely crypto-creationists.

    Historical Precident does not imply continuity.

    quote:
    Myth: The theory of intelligent design claims that the designer is the God described in the Bible.
    ...
    Fact: It is a matter of formal logic, not deception, that allows one to consistently accept the intelligent design argument while utterly repudiating the theory of creationism as well as the Bible itself and its God.

    Again, true and misleading. You can have ID and no monotheistic God (flying spaghetti monster, anyone?) - but I have yet to see ID propogated by someone who was not a Christian. (Incidently, ID seems to break down unless you have a (probably monotheist) God that was outside time because you need something to make that God - it certainly couldn't have arisen by chance, meaning you iterate back to either a God or a paradox).

    Besides, ID is usually fought on the grounds that it is not science and that almost the testable examples so far have been shown to be wrong. Whether or not it is Christian Creationism is largely irrelevant here.

    quote:
    Myth: Conservatives and Christians necessarily accept the intelligent design argument.

    Jean Chen (Pop & Politics):

    “Intelligent design is just another strategy from conservative Christians to ban evolution.”

    Fact: You can consistently be a political conservative or a devout Christian and still totally reject the argument from intelligent design.

    Serious strawman here. I have yet to see anyone claim that all Conservative Christians accept ID or Creationism. Let alone anyone saying that all Conservatives and all Christians accept ID. (The closest I've seen is the claim that all who accept ID are Conservative Christians. This is not the same as saying all Conservative Christians accept ID).

    quote:
    Myth: The theory of evolution and monotheism are logically at odds or, at least, inimical.
    ...
    Fact: You can consistently accept the theory of evolution and still be a monotheist, seeing the hand of God in the evolutionary workings of the universe.

    He has a point here- and I detest the Dawkinsites when it comes to religion as much as I do YECies.

    In short, he's dealing with the lunatic fringe and thinks he's making a telling point. At least he seems to have a (rather trivial) point here. Still, I suppose if you throw enough mud, some of it will stick.

    To summarise, the link you give is neither informed, nor fair, nor honest despite your assertions to the contrary, FS. I thought better of you.

    As for the Rosenhouse blog article, I wouldn't be so quick to claim that he has already "invented the wheel". From where I'm sitting this so-called wheel is completely square. Consider his statement below:

    Well, that is certainly a novel thesis. He definitely gets marks for imagination – or should that be paranoia? - if not for factual correctness, logical consistency and relevance to the point at hand.

    Rosenhouse’s ambiguous comment about “idiocy” is very appropriate. I think you'll find that all his wheels have fallen off. I would stick to walking for now.

    Um, no. The point is obviously that classical Greek thought is a red herring that doesn't have a whole lot to do with ID.

    If you are going to grossly misconstrue Rosenhouse's blog entry like that, there is little point in arguing with you.

    I think the misconstrual here is yours.

    Cohen’s original point is that present ID ideas are simply the latest form of a school of thought that has been around for over 2,500 years. The difference now is that the present ID community has access to mathematical tools and scientific knowledge unknown in the classical period. That has enabled the argument to be restated in a much more vigorous fashion.

    quote:

    I think you’ll find that the fundamental misconstrual is with Rosenhouse himself.

    The OT (“the founding document of creationism”, according to Rosenhouse) is revered by Jews, as well as by Christians of all stripes. Indeed, it was Jewish scripture long before it became Christian scripture. Only in the Christian era was it disseminated widely beyond the Jewish community.

    The “scientific creationism” (sciat young earth creationism) that Rosenhouse attacks is associated with a particular strand of evangelical Protestantism, mainly in the late 20th century USA . Such ideas have found little support in the RC, Orthodox and mainstream Protestant churches, despite their having a vigorous theological doctrine of creation.

    It therefore follows that access to the OT is not a sufficient criterion for the development of “creationist” ideas. As a matter of historical fact, regardless of the date of its writing, it is in any case impossible that Plato had access to the OT in a language he could understand, since its translation into Greek was only made several centuries after the classical period, in circa 250BC.

    Rosenhouse therefore misunderstands Cohen’s argument completely and so his attempted rebuttal fails.

    Again, that is Rosenhouse's viewpoint, but his arguments utterly fail to substantiate his position. "Scientific creationism" is an attempt to support a literalistic interpretation of the book of Genesis through some very selective scientific understandings, such as "flood geology".

    By contrast, the ID world's arguments are specific to a very limited area (the detection of intelligent activity) and are made on logical, rational and scientific grounds. They say nothing about gods, scriptures and religions. On these issues one may adopt any view one likes.

    ID ideas are fully compatible with accepting the established scientific age of the world (4.6 billion years). They are also compatible with accepting some notion of common evolutionary descent, either in its universal form, or in some modified form, depending on how one reads the palaeontological evidence.

    I would also add that ID ideas are fully compatible with Francis Crick's panspermia hypothesis (basically, space aliens "seeded" this planet) and, frankly, even the bizarre "Gaia" hypothesis of the whole Earth as a single living entity.

    What ID ideas contest vigorously is that the Darwinian mechanism of random mutation and natural selection is adequate alone to explain fully the historical development of biological complexity. Other than that, ID ideas are fully compatible with some form of evolutionary development in history.

    If Rosenhouse can't see the crucial differences betwen the YEC world and the ID world, then his credibility as a commentator is utterly destroyed.

    quote:

    If Rosenhouse thinks that the only opposition to Darwinism came from Genesis literalists brandishing the KJV, he is sorely ignorant of the history of scientific thought in the 19th and 20th centuries.

    Rosenhouse did not contend otherwise, and nor do I. Rather, it is noted that both the old scientific creationism and the new ID are pseudoscientific attacks on Darwinism. It is also noted that ID came to the fore after scientific creationism failed in its political goal of making headway into schools. It is for these reasons that ID is considered just another form of creationism, a form that is far more pared down in its claims, but a form of creationism nonetheless.

    From memory Russ's initial quotation looks like it is mine from a while ago.

    Your point about deductions from what is observable within the universe is a good one. ID theory has been developed on precisely those sort of rational grounds.

    The "beef" is whether these computer models actually reflect what is being claimed by scientists about Darwinian evolutionary theory. Personally I think that there is some very serious confusion afoot.

    The computer models demonstrate that emergent behaviour and increasing complexity can occur. The fossil record shows that increasing complexity does occur. Darwin's theory provides the link between them.

    You're either using a meaning of "specified" so esoteric as to be previously unknown; or moving the goalpost; or asserting a true but irrelevant fact.

    Case the first:

    You seem to presuppose that Darwinism (in its loose definition as in the thread topic) assumes purpose. It doesn't.

    ID introduces "specification" to the topic.

    Case the second:

    Darwinism increases information, but now you want "specified information"

    Case the third:

    A parallel statement would be

    Relativity isn't that robust when it comes to generating pseudo-random numbers.

    At the metalevel, you're doing what I think of as the "usual creationist thing" - focusing on one trivial point to try to presuade people that the complex interralted web of scientific truth isn't really there.

    Following some advice from Alan Cresswell on these boards, I've been, patiently, slogging my way through the ID argumentation. Given the length of this thread, I haven't checked to see whether what I am doing now if repetition. It may be -and if so I apologise to the contributors.

    I have now read quite a lot of Behe and Dembski on the Net - there is a fair bit there. No doubt I am not nearly as conversant with their work as you are. I would like to propose what may be a more constructive way of looking at the ID argument. A test case. Looking at a specific paper from the works of Behe and Dembski. One which contains testable arguments, or evidence. But one which would be accessible to the SofF community, whether they have a scientific background.

    I begin with an example and two preliminary questions. Firstly, does this paper by Behe, presented to the C S Lewis society, satisfy the criteria I have put forward? Secondly, do you believe it is a good example? If you would prefer another example, please feel free to choose it. If you would prefer not to go down this road at all, that is also fine with me. Given that your POV in this thread is a minority one, I think it only fair that you should control the choice of any test case paper - or have the option of deciding not to take part.

    From my POV, the Behe paper expresses some scientific arguments, with supporting evidence, to an audience which was Christian and probably included people from many different backgrounds (including scientific). I found it quite accessible, even though I haven't personally practised science for many years. (I am an ex-Chemist who forsook the lab for IT systems design and development work).

    Over to you.

    That the codes used in genetic algorithms are human artefacts isn't in doubt. The question is, are they entirely human constructs, or do they expoit processes that also occur in nature. To illustrate the question, allow me to shift example. Most scientists and geologists have no doubt that minerals form through entirely natural processes, and yet various human devices akin to glorified pressure cookers can simulate the natural conditions these minerals form in and create artificial minerals. Does the fact that a machine designed by intelligent beings can create minerals mean that minerals found in rocks were also created by a "machine designed by an intelligent being"? I would say that that doesn't. The ability of intelligent beings to recreate a process doesn't mean that that process doesn't occur without any intelligence designing the process. That's true for genetic algorithms as well as mineral production.

    Yes, I was extremely puzzled by FS's comment here. He'll have to defend it himself. But I had an analagous, though not necessarily all that related point. I think most of us know that when Dawkins writes about the "selfish" gene he is using language in a particular way (I sometimes think, cynically, to help sell popular books on science). The language says something, but has caused as much confusion as enlightenment.

    I'm not sure of the extent to which FS is copying Dawkins (now that's a fragrant thought) in this sort of use of language but I suppose he might be. Or he might be implying that the mechanical, behaviour of orgnaisims which are in themselves non-sentient, demonstrates, by some paradox, some sign of sentience anyway. A sort of "echo of the designer", who might of course be anyone (or Anyone, or Someone). If you see what I mean. Who can tell?

    It will be up to him to cough when he can - meanwhile there you have a puzzled, guessy type view. Liked your post BTW - your field of study sounds interesting. Also BTW I've guessed that quorum sensing (new term for this ignoramus) means a sort of beehive behaviour type thing - if that's stupid please feel free to show me up.

    I hope to come back to the other posts some time tomorrow, but for now I want to comment on this point.

    From a literary perspective Richard Dawkins is actually a very good writer. His prose is clear and lucid, and not without its poetic touches. His descriptions of animal behviour are a joy to peruse. For the general audience that he has in mind, his style is ideal.

    Where Dawkins' writing falls down is at the point where we leave behind general information and enter the serious world of hard science. He does not write with enough precision for this purpose and in consequence skates over important technical issues. His elegant writing simply does not stand up when we begin to ask, "Yes, but how does he know that?"

    So, I am not consciously copying Dawkinss' style, but nevertheless I would be happy to write to the same general standard as he does, provided that I could also move into a more precise style for occasions when full technical detail is required.

    Your unfamiliarity with the writings of the ID community explains why we are talking past one another. Since you haven’t studied the present ID proposals at all, I cannot give much weight to your opinion that it is “another flavour of bogus theory” or “unnecessary”. The argument is intensely focussed on the different types of information and on just what kind of information purely natural processes can generate.

    From your previous posts you have some mathematical ability and, in particular, a knowledge of statistical entropy and Shannon information theory. On that basis you should be able to understand at least some of Dembski’s line of argument regarding “design” (by which he means the quantitative detection of intelligent agency). The argument has moved on substantially from the “argument from design” associated with Paley in the 18th century.

    According to this Wikipedia article, the Strong Anthropic Principle is consistent with ID ideas. The arguments that Dembski and co. are producing are substantially more subtle and nuanced than many people give them credit for. If you prefer “a more subtle God” you might find their ideas striking a chord with you. They certainly have with me.

    Following some advice from Alan Cresswell on these boards, I've been, patiently, slogging my way through the ID argumentation. Given the length of this thread, I haven't checked to see whether what I am doing now if repetition. It may be -and if so I apologise to the contributors.

    Firstly I salute your intention to study some of the ID arguments for yourself and the fact that you have read some of the well-known authors in this field. To be honest, if anyone is new to this subject, then this thread is not the best place to start. It rambles all over the place and at times is more likely to confuse than enlighten. Some of the discussion has been intensely technical and therefore well over most of the Ship’s head for unavoidable reasons.

    For total newcomers to the subject I recommend the Access Research Network (ARN) website. This is some kind of educational foundation in the USA and I see that you have found it already.. This site has many articles, links and dedicated forums available. They also sell subsidised books. The scientific standard on this site is high.

    quote:
    I have now read quite a lot of Behe and Dembski on the Net - there is a fair bit there. No doubt I am not nearly as conversant with their work as you are. I would like to propose what may be a more constructive way of looking at the ID argument. A test case. Looking at a specific paper from the works of Behe and Dembski. One which contains testable arguments, or evidence. But one which would be accessible to the SoF community, whether they have a scientific background.
    Your proposal is very fair and reasonable. Many ID writings are widely available on the Internet, and Dembski in particular does make an effort to differentiate between those papers he addresses to a more general audience, and those that he addresses to serious mathematicians. I will give some effort to locating something that may be suitable for this purpose.

    quote:
    I begin with an example and two preliminary questions. Firstly, does this paper by Behe, presented to the C S Lewis society, satisfy the criteria I have put forward? Secondly, do you believe it is a good example? If you would prefer another example, please feel free to choose it. If you would prefer not to go down this road at all, that is also fine with me. Given that your POV in this thread is a minority one, I think it only fair that you should control the choice of any test case paper - or have the option of deciding not to take part.
    I couldn’t get your link to open, but I think this is the Behe paper to which you refer. Behe is a professor of biochemistry and particularly associated with the concept of irreducible complexity, which he introduced in his book Darwin’s Black Box. Some of his arguments require a lot of technical biochemical knowledge to understand and critique fully.

    The concept of irreducible complexity has been discussed before on this thread several times before. It is an important concept that seems intuitively correct to me as an engineer. It describes the evolution of a certain kind of biological feature as a mathematical step function over time in terms of the biological functioning.

    However, even if this concept were to be comprehensively rebutted in the biological world, that would not of itself falsify other ID ideas on evolution. For that reason it may be better to concentrate on something Dembski has written rather than Behe. Dembski has the more fundamental concept of “complex specified information” (CSI) and much of the ID argument hangs on that.

    quote:
    From my POV, the Behe paper expresses some scientific arguments, with supporting evidence, to an audience which was Christian and probably included people from many different backgrounds (including scientific). I found it quite accessible, even though I haven't personally practised science for many years. (I am an ex-Chemist who forsook the lab for IT systems design and development work).

    Over to you.

    Someone with a general level of scientific literacy should be able to make an informed opinion of these ideas and their worth. To understand and critique them fully requires a lot more knowledge, especially mathematical. The argument is also very subtle and nuanced at times. It is easily misunderstood and in some places, wildly misrepresented by others.

    I have been following this debate for over five years now. My own ideas and understanding have been refined several times during that period, partly as a result of the excellent debate that I had last year with Glenn Oldham, who was nevertheless no supporter of ID proposals.

    That the codes used in genetic algorithms are human artefacts isn't in doubt. The question is, are they entirely human constructs, or do they expoit processes that also occur in nature. To illustrate the question, allow me to shift example. Most scientists and geologists have no doubt that minerals form through entirely natural processes, and yet various human devices akin to glorified pressure cookers can simulate the natural conditions these minerals form in and create artificial minerals. Does the fact that a machine designed by intelligent beings can create minerals mean that minerals found in rocks were also created by a "machine designed by an intelligent being"? I would say that that doesn't. The ability of intelligent beings to recreate a process doesn't mean that that process doesn't occur without any intelligence designing the process. That's true for genetic algorithms as well as mineral production.

    You raise an extremely good question that goes to the heart of this issue. Just what kind of creative processes can take place in the natural world without recourse to anything other than the basic laws of physics and chemistry? ID attempts to answer this question scientifically. The natural world is clearly capable of many things on its own, but is there any kind of discoverable limit?

    Your argument breaks down in the final sentence. Is the full equivalent of genetic algorithms actually occurring in nature? This is the nub of the debate and I have argued earlier on the thread that it is not. With respect to geology, the natural state of minerals formed by geological processes alone cannot be characterised by what Dembski calls “Complex Specified Information” (CSI).

    (Be careful, he is using that phrase in a precisely defined technical and quantitative sense. It’s best to read up on this in his own words.)

    However, if we found mineral deposits containing any form of CSI (e.g. a clearly spelled out and recurring sequence of prime numbers from 2 to 101, or a message in a recognisable language, or some other form of detachable pattern), then would we still infer that only natural forces had been at work? Or would we infer something else instead?

    This is where Dembski argues that CSI is a reliable indicator of intelligent agency. In his argument, neither chance, nor necessity, nor both in combination, can create CSI. The only thing we know that can is intelligence. Please note that his argument, however, says nothing about the nature of that intelligence.

    I'm an arts student, so I don't have the technical knowledge to make any sensible comment about CSI. But surely scientific methodology would rule out intelligence a priori, on the grounds that it's not a useful hypothesis?

    i.e. If we assume that CSI comes about as a result of an intelligent entity, then that's more or less the end of the road for scientific investigation in that area. An intelligent entity's actions are, pretty much by definition, unpredictable.

    If we assume that intelligence was not involved and that there's some other factor that we haven't discovered, then we may be wrong, in which case we'll be stumped, but no more stumped than we were before. If we're right, though, then the discovery of this factor opens up a whole new field of scientific investigation.
     
    Posted by Alan Cresswell (# 31) on :
     
    Ricardus has it right, IMO. Who said arts students know nothing about science?

    If you take a definition of CSI that is something like "information present that is sufficiently complex that it must be the result of intelligent action" thenyou can go and look for examples of CSI. However, any real world example (excluding things of human construction) can only, at best, be apparent CSI - you can never rule out the possibility that this complex information came about by some route that did not involve an intelligent agent - though there may well be instances where the probability of non-intelligent agency is very low. As scientists, fruitful research can only come about by further examination of this example of apparent design as though it were not intelligently designed.

    Incidentally, the reverse is also true. You can never prove something was caused by entirely materialistic means without the input of an intelligent agent either.

    Which puts the whole "intelligent agent" (excluding human agents) concept outside the realms of science.

    I've included the exception of human agency, because I do believe that investigation of human artefacts can be done scientifically. There is, of course, still a grey area of "Possible human artefacts" (eg: "is that flint shaped that way cos it fell from a cliff and happened to shatter into sharp shards, or was it shaped by humans for a purpose?") where the mathematical concept of CSI could, I suppose, help clarify things.

    Indeed. ID is a slightly modified form of Creationism that doesn't require a strict adherence to a literal interpretation of Genesis, yet retains the "Creation Science" faith that there will be scientific evidence of the Creative activity of God. Oh, and ID is also very coy about naming God as the Intelligent Designer, not that anyone has any serious doubts about that is who they really mean.

    Which is a shame really, because strict adherence to a literal reading of Genesis and the Creator God of the the Judeo-Christian-Islamic tradition is at least a basically logically consistant position to stand on. ID seems to stand on rather shifting sands when you remove that philosophical foundation.

    Though I've likened ID and Creation Science in this post, I do recognise that they clearly have very different attitudes to Biblical Literalism, evolutionary science etc, and that as a result both ID and Creation Science disassociate themselves from each other. I'm not claiming any simple correspondance between these positions, but there are IMO some definite similarities in the basis of these approaches.

    The similarity, to me, is that both of them expect to find support for an essentially philosophical position in science - I'd say that's something they also share with Dawkins et al. By this I mean that these people (all of the above) tend to start with an assumption (YEC - the God of the Bible created as recorded in a literal interpretation of Genesis; ID - there is an intelligent agent behind the material universe; Dawkins - there is no external intelligent agency) and then go to look for support in science. In the case of Creation Science I'd say that most of the time that support is found in some extremely poor science. In the case of Dawkins, the science he goes to is good. I suspect that IDers may find themselves somewhere in between.

    The contrast to most scientists is that they have rejected aiming for the greatest level of objectivity possible. Scientists go to the material universe to find out what it's really all about with the minimal amount of preconceptions about what they'll find. If the material universe contains scientific evidence for the presence of a Creator, an intelligent agency behind the design, or none of the above then fine. But to do science to look for such evidence isn't the same thing.

    The commonality between YEC, ID and Dawkins is that they do science for a reason other than just to find out what the material universe is.

    BACTERIAL INTELLIGENCE

    First off, this subject requires an extensive knowledge of microbiology, biochemistry and genetics to discuss in full detail. These are not my specialist subjects. It’s my impression from the outside that the concept of bacterial intelligence is new to microbiology and is currently the subject of much research and discussion.

    In this post I am therefore simply going to give some basic information sources and explain why the concept of bacterial intelligence has found sympathetic listeners in the ID community. Anyone with particular knowledge or interest in bacterial intelligence is welcome to pick this topic up and run with it as far as they can.

    Firstly, JimmyT used the term “quorum sensing”, which was new to me. A short article explaining what it means and giving me many more links is here.

    On the general subject of bacterial intelligence, a quick Google search revealed the following articles. These are relatively short and quick to read:

    http://kb.muxspace.com/brooding/bacterial_intelligence

    http://www.world-science.net/exclusives/050418_bactfrm.htm

    http://news.bbc.co.uk/1/hi/sci/tech/1542539.stm

    http://www.csd.uwo.ca/dna11/abstract_Eshel.html

    A much longer and full-weight journal article can be found here. Although this article is long, I can particularly recommend it. Even as a non-specialist, I was able to follow most of it. It has some amazing colour pictures and is well worth reading for insight into the remarkable abilities of bacterial colonies.

    (Please not that the word “complexity” in this article is being used in its broad, everyday, dictionary sense. It is not to be confused with the very particular way that Dembski defines and uses the term “complexity” in ID theory. He explains his own use carefully.)

    As I have stated several times, the ideas contained within ID theory do not automatically imply a theological corollary. It is possible to make deductions from this theory in a very different direction. One such direction is called Endogenous Adaptive Mutagenesis (EAM). This is one particular form of a non-Darwinian evolutionary theory. There is more information on EAM here.

    quote:
    EAM is the 'multiple designers' version of Intelligent Design. It holds that every organism possesses intelligence to some degree, and that it uses that intelligence in an unconscious, instinctive way, to redesign itself and/or its behaviour, and that of its offspring, in the face of novel, crucial environmental demands. Ecological adaptedness, that is, balance between environmental pressure and an organism's capacities, replaces the 'competitive' Darwinian notion of differential 'fitness' between organisms, in the teleology of EAM.
    EAM is to be clearly distinguished from historical Lamarckianism due to the vastly superior knowledge of microbiology, biochemistry, and genetics that is now available. The recently discovered phenomenon of epigenetic inheritance also appears to be relevant to the issue of EAM. The existence of bacterial intelligence (if and when it is fully confirmed) would certainly be consistent with the EAM school of thought, hence the ID interest in this subject.

    EAM is also one possible explanation for the undisputed phenomenon of antibiotic resistance. Far from this development being dependent on the operation of a random mutation/natural selection mechanism, some hold that it is caused by the ability of a bacterium to intelligently manipulate its own genome to its own advantage in the face of an antibiotic threat. That would be an example of EAM in action, and a form of ID evolution.

    FS - despite my two science degrees, I fail to see how your links prove your point.

    They just state that bacteria can be observed doing complicated things. This isn't really news to anyone. I don't see how it therefore follows that they have some kind of inherent intelligence.

    I certainly don't see how that explains antibiotic resistance (because following that line of reasoning, a bacterium would have to wake up in the morning, get out of bed and say to itself 'You know what, I am getting a bit sick of this nasty antibiotic - what I need to do is redesign myself to make myself resistant to it. Excuse me whilst I find that a bit unlikely). A more obvious solution is that there is no intelligence involved and that random genetic mutations cause some individuals to me more - or less - resistant to the antibiotic. If there are sufficient individuals with the resistance then the population expands with the new antibiotic resistant trait.

    The problem with your explanation is that a) why millions of individual bacterium let themselves die when they could have the intelligence to 'switch on' the resistance b) there is masses of evidence of populations behaving in this way and no evidence of them using any form of intelligence.

    Of course, you might be using "intelligence" in a way that I don't understand.

    Imagining for a moment that EAM is correct, and I suspect it is not for the reasons Cheesy points out, then presumably EAM would be detectable in nature through the techniques of methodological naturalism.

    If hard scientific evidence for EAM were detected, could we then expect to see a retraction of the claim that methodological naturalism is a flawed technique?

    I have a question about ID which I don't think has been covered. (I found a post back on page 10, but I was not very happy with it).

    First, some background. I work in a field in which we have to develop highly detailed models ('theories') based on very weak data. As a result, we have to treat all our models with a great deal of skepticism. A model cannot be accepted on the basis of how well it explains the existing data, but only one the basis of its 'predictive power': how well it predicts data which it has never seen.

    In fact, since we collect all the data which is relevent to a particular problem, we deliberately set aside 10% to use for this testing once the model is complete. This is a statistical technique called cross-validation (not to be confused with a theory of the atonement).

    I would like to suggest that the 'predictive power' of a theory is a principle means of testing theories in science. If I may offer a couple of illustrations: In 1887 the Michelson-Morley experiment, designed to detect the Earth's absolute motion in space, produced a null result, failing to detect even the Earth's motion about the Sun. In the long run two explanations for this result remained:
    Special relativity remained controversial (indeed Einstein received his Nobel prize for other work), until 10 years later the theory of general relativity predicted precession in the orbit of Mercury, and an experiment was set up specifically to test this prediction. The prediction was confirmed.

    Another example would be in quantum mechanics, in which two alternative theories: the Copenhagen interpretation and hidden variables, were long thought to be indistinguishable, except by an impractical thought experiment. Recently it became possible to perform that experiment, leading to the rejection of hidden variable theories.

    How does this apply to evolution and ID?

    Evolution, in comparison to theories like quantum mechanics, has been comparatively spartan in providing new predictions: see this page, although the evidence from protein sequences is extensive. I guess one issue is that it is harder to make predictions in biology than physics due to the complexity of the systems. However, it is only fair to ask the same questions of ID:


    I have some more stuff to post on cross-validation, but I'll leave that for another post.

    I submitted the links as evidence that the concept of bacterial intelligence is being discussed in the scientific community. It is one possible interpretation of the experimental data. I agree that it remains to be a conclusively proven concept.

    Many bacteria obviously die before they find the right genetic mutation and the resistance develops. However, with concepts such as bacterial communication and bacterial altruism, it is not difficult to see a rational and intelligent strategy as one possible explanation for their behaviour.

    That appears to be a fair statement as far as I understand EAM. Remember, ID theory says nothing of necessity about the nature of the designer. It follows that in some cases the designer may well be readily accessible to further scientific investigation.

    No.

    Methodological naturalism is a potentially “flawed technique” in so far as it presupposes the nature of nature. Remember, many people only go looking for what they expect to see, and then, even when they stumble on something highly significant, they sometimes fail to recognise it because of presuppositional blinkers.

    Read this essay on “The Neglected Elements of Scientific Discovery” by “Mike Gene” (a pseudonym) at the TeleoLogic website. He is another professional biochemist and ID theorist. If I recall correctly, he self-identifies as an agnostic.

    The Michelson-Morley experiment is an extremely good example of an observation that discomforted the existing theory of “luminiferous ether” without immediately knocking it from its position of dominance. This would be in accordance with Thomas Kuhn’s notions of what it takes to topple a scientific paradigm.

    The presuppositions of the time found special relativity to be a “plainly bonkers” idea, so it settled for the “intellectually unsatisfying” notion of ‘ether dragging’. It took the wider acceptance of special relativity and some spectacular confirming cosmological observations to finally put the “luminiferous ether” theory to bed circa 1930.

    Just out of interest, are there any competent physicists today who still hold to the theory of “luminiferous ether”?

    Please note that ID theory does not rule out evolution per se (“biological descent with modification”). However, it does have some very definite negative comments on the adequacy of Darwinian mechanisms (random mutation/natural selection) to produce historical change and development in life-forms.

    Again, don’t confuse what may be evidence for some form of common descent with the specific claims for the ability of a Darwinian mechanism to bring about that biological change. ID per se says nothing about common descent either way. One is free to make any reasonable deduction from the palaeontological and biochemical evidence.

    (Given the field and the newness of the theory, it is perhaps unreasonable to expect any predictions at this stage. However, it shouldn't be too early to ask a second question...)

    Dembski discusses testability in section 6.9 of his book “No Free Lunch”. For him “testability” not only includes Popperian falsifiability, but also “confirmation, predicability [sic – note the deliberate absence of the letter T], and explanatory power”.

    His theory hangs on his concept of Complex Specified Information (CSI), a rigorously-defined, quantifiable concept tied in to information theory. He predicts that unintelligent, non-teleological, natural processes cannot generate this form of information. Nevertheless, he predicts that the natural biological world should be full of CSI.

    He also predicts that we will find certain patterns of technological evolution in biology, namely “sudden emergence, convergence to ideality, and extinction”, and that such evolution will be (mostly) via a non-Darwinian process.

    (In particular we are interested in predictions which would distinguish ID from evolution. Note there is one problematic possibility: that there is a designer who is designing to give the appearance of evolution. This of course is untestable).

    Your question is presuming that ID is automatically against all notions of evolution in the general sense of the word. As I have said above, this is not the case. This appears to a widely-held misconception on these boards.

    Your point about the intelligent designer trying to disguise his/her/their/its actions is a good one. ID theory cannot distinguish between genuinely non-designed events and those designed events skilfully disguised by an intelligent agent to look like non-designed events.

    Dembski’s “explanatory filter” may therefore assign an event to chance or necessity (his two other categories of non-designed events apart from designed events), even though it has in fact been designed. However, the filter reports a designed event if and only if such an event has truly been designed.

    Bacterial communication and altruism eh? New one on me. I agree, my explanation was a caricature - according to your explanation bacteria act as a co-operative and make a joint decision based on the threat. I wonder if this is a democratic one-bug-one-vote system. I'm sorry, I find that explanation laughable when we are talking about single celled organisms.

    I suspect your explanations of intelligence are totally different to those in this corner of the academic community, Neil.

    Given that your explanation depends on you having a grasp of the same idea - I suggest to you that if you are going to use this as an example it might be kinda important to check you know what they are talking about. I very much doubt that anyone is talking about a conscious decision on the part of microrganisms to deal with a perceived threat.

    I suggest to you that "intelligence" refers to the capacity of the microbe genome to mutate and provide resistance to antibiotics.

    FS, I just want to point out that if you wish to have an academic discussion, you should at least provide evidence which is more than the google equivilent of something you find on the bottom of your shoe.

    Hurrah, a real paper.

    Given that you have only provided one paper in evidence - and that we can easily ignore all your other links - maybe you would now be kind enough to tell us/me how this paper proves your case.

    Remember, the case that you are trying to prove is that bacteria either individually or collectively have an intelligence which they use consciously to attack antibiotics.

    Bacteria have no direct influence on mutations in their own genome - and I've never heard anyone postulate such nonsense.

    I suggest to you that "intelligence" refers to the capacity of the microbe genome to mutate and provide resistance to antibiotics.

    From the paper:

    quote:
    Bacteria use their intracellular flexibility, involving signal transduction networks and genomic plasticity, to collectively maintain self and shared interpretations of chemical cues, exchange of meaning-bearing chemical messages, and dialogues. The meaning-based communication permits the formation of colonial intentional behavior, purposeful alteration of colony structure and decision-making – features we might begin to associate with bacterial social intelligence. Such social intelligence, should it exist, would require going
    beyond communication to encompass additional intracellular processes, as yet unknown, for generating inheritable colonial memory and commonly shared genomic context.

    Whatever the full story subsequently proves to be, the authors of this recent paper certainly do not consider the concept of bacterial social intelligence to be a laughable concept. They sketch out what they mean by intelligence in the short extract above.

    Note that "meaning based communication" also underlies spoken human language. Language is much more than simply pressure waves in the air. It is a high-level concept indeed.

    That's why I differentiated between the short, lightweight links that are easily read, and the much longer article that has to be printed out and read away from the screen, because it is too detailed to do otherwise.

    I think you'll find it's the antibiotics that attack the bacteria, and not the other way round. In their defence against antibiotic attack it is possible that bacteria may employ intelligence of some form.

    I am not trying to "prove a case" in a formal sense. I am providing evidence of an ongoing scientific discussion.

    I have some background in the bugs bit of this (as, I believe, does JimmyT); but no background in the first 20 page; so I'll restrict comments to the bugs.

    It is true that bacteria increase mutation rates under antibiotic pressure. Sometimes this can be traced directly to the antibiotics interferring with DNA synthesis. Sometimes this is a result of a stress response in the bacteria, consequent on the antibiotics.

    This is probably useful in nature; bacteria coming into contact with new antibiotics are likely to find a way round it; and one can argue these kind of mechanisms would be positively selected by evolution.

    Quorum sensing is a related concept referred to elsewhere; bugs at certain densities sense it, and behave differently.

    So mechanistic explanations which give the appearance of intelligence are possible here.

    Yes, but this is not what you are saying it is, Neil. There is a vast difference in some primitive sort of chemical communication between single celled organisms and the kind of genetic choices that you are suggesting bacteria are making in the presence of an antibiotic.

    I'm sorry Neil, I do not believe you understand this paper at all. You are ascribing higher organism functions to single celled organisms.

    For goodness sakes, with a million individual microbes in every 1g of soil, they could destroy all other life if they worked together with the kind of intelligence you suggest.

    Really, Neil, you would do best to stay within your own expertise and not stray into areas where you make assumptions about their use of jargon.

    I've done a fair bit of higher study in microbiology; so perhaps I pass your test Cheesy. I'm certainly not with FS on most of this, but I'm not entirely with you either, Cheesy. I think the idea of social intelligence among bacteria is not so far fetched, and seems well referenced and argued.

    I think there are real similarities between the behaviour of bacteria and neural networks.

    Although that may be a nail in the coffin of ID; It is quite clear from bacteria that the elements required to produce a complex, apparently sentient, behaviour pattern can be evolved. Indeed, the author of the review FS quotes finishes with "We might even discover that the last five decades of evolution in bacterial social intelligence is largely a result of their encounter with our socially irrational massive use of antibiotic materials......"

    Fascinating review.

    OK - please explain the term 'social intelligence' to me and if possible how it might mean that bacterial communities are able to affect the mutation of their own genome to combat the effects of antibiotics. My education is very flawed in this area.

    I might be wrong, but I understood that neural networks, whilst being able to perform some complex tasks, cannot really be ascribed the intelligence.

    And to be clear, I could be completely wrong about though I did study some microbiology at university. The ideas just sound incredible to me.

    You certainly don’t read my posts, do you? I stated clearly that microbiology, was not “my specialist subject”. I also invited those with specialist knowledge in this area to contribute. My thanks to mdijon for his/her contributions.

    The subject of bacterial intelligence is frankly somewhat tangential to the mainstream ID issues that I have defended to date. Whether this proposal is subsequently vindicated or overturned does not affect the overall ID theory. However, I can see that an overturning may upset the EAM crowd.

    That is precisely the point at issue in the debate. What is the appropriate language to describe the behaviour of bacterial colonies? Is it even appropriate to talk about bacterial intelligence at all? If so, what kind of intelligence is involved? How could such intelligence be characterised? To what is it analogous?

    Aren't we getting a bit het up about nothing here?

    Yes, "intelligence" is a silly word to use about bacteria, but bacteria certainly exhibit behaviour, and they change their behaviour.

    Just in order to make our language simpler we can talk about bacteria "intending" to do something, or doing something in order that they achieve some goal. I doubt if anyone at all thinks that that means we assume the bacteria have thoughts or ideas or emotions or intelligence in the way that animals do. Its no different from saying that a plant grows towards the light so that it can photosynthesise. We can even talk about bacteria "choosing" between one life state and another or one behaviour and another. With the possible exception of some aspects of motility effectively all bacterial behaviour is mediated through differential gene expression - a bit more of this protein, a bit less of that. In effect behaviour, gene expression, cell state, life cycle, and phenotype are not separate categories when talking about bacteria.

    Ideas of altruism & so on are no more problematic when used about bacteria than when used about any other organism without a brain. And we know that bacteria often - probably usaually - co-operate within and between species, and form quite complex multicellular structures.

    Mutation rates evolve along with any other characteristic of an organism - though there is no real reason I know of to think that any special "intelligence" is required. Some bacteria have mechanisms to take in foreign DNA under certain circumstances and some of them are more likely to take in foreign DNA when under certain kinds of stress. That will tend to up the mutation rate...

    NB the idea of epigenetic inheritance is not new. In fact it is at least a century older than modern genetics. Though the word "epigenesis" was once used to mean something rather different what what it means now - it was introduced to describe what we might now call embryonic development as opposed to preformation. But in the sense it has been used on this thread it has been an accepted part of modern genetics since maybe the 1920s. Nothing mysterious or weird about it at all, which is not to say it can't get to be confusing, especially when mixed up with handwaving about emergent properties. Also a lot of what is now called "epigenetic inheritance" is really nothing more than straightforward control of gene expression, for example by methylation & demethylation of DNA, autosomal imprinting & so on.

    The Science Citation Index currently has 6,246 references for "epigenetic" and 293 for "epigenesis". Along with epigenetics we also have epistasis, pleiotropy & penetrance... each bits of genetics jargon for some of the many reasons why it is very naughty to say "a gene for" something.

    But none of this has anything to do with whether or not evolution by natural selection is a good explanation for the origin of species. All these things are just as subject to natural selection as simple Mendelian genetics. In fact for the first 70 years of the general acceptance of evolution & common kinship, Mendelian inheritance was unknown, or ignored, or thought incapable of explaining evolution, and these other ideas were used instead (along with a whole load of even more handwaving ones that have been discarded since)

    Cheesy (and slightly Ken), I think the term "Social intelligence" is being used to describe what is seen. The bacteria, as a community, behave in apparently intelligent ways. In a sense this isn't new; it's been known for some time that bugs adopt different properties dependant on their density, which seem to help survival of the overall infection, rather than any individual bacteria.

    It is described as intelligence because of the outcome; this doesn't imply consciousness, or any other higher function - so yes, it might be a silly term to use here, but that's what they chose.

    In what way are these, and neural networks "not intelligent". I think it is becoming harder and harder to define what makes "artificial intelligence" different from intelligence.

    I see all this as supportive of evolution per se, rather than ID.

    Very well put. Without some objective tests for the colloquial terms of consciousness (maybe conscious self-awareness), to imply "intelligence" from outcome no longer seems to be very safe to me. The colloquial meaning and the technical meaning of the word overlap, again putting pressure on intelligent (oh there I go again) discussion.

    ID theory supports a “design inference”, which is understood as evidence for the actions of an intelligent agent. The theory of itself says nothing about the nature of that agent other than he/she/it/they are intelligent.

    In section 6.1 of No Free Lunch Dembski outlines a possible research strategy for ID theory. He provides 11 lines of research that are clearly scientific and fully accessible to further scientific investigation. He also provides an additional 4 lines of investigation that move increasingly away from science into non-scientific areas. This movement away from science he clearly acknowledges.

    This section of the book is similar to this article at the ARN website, except that the book has 15 in its list and the article only 14. The last 4 are identical in the book and the article, namely the problems of ethics, aesthetics, intentionality and identity.

    So in Dembski’s thought one is certainly free to investigate who or what is the designer implied by ID theory. However, one needs to be aware that this line of investigation may or may not take one beyond the realm of science. Dembski is on record somewhere as developing his personal ideas about the designer with reference to the logos theology of St. John’s gospel, but he is very clear at this point that he has left science behind and entered the realm of personal faith. This move is completely optional as far as the theory goes.

    If the designer is some hitherto unknown natural intelligence or teleological property of the biological world, then that should indeed be discoverable by the normal scientific method (as the EAM crowd are suggesting). The important point with ID theory is that it breaks free from the suffocating constraints of a philosophical naturalism.

    I hope that answers your question. Please feel free to ask more.

    Incidentally, if you are mathematically literate, you will find extensive technical discussion on pages 11 to 14 of this thread on evolutionary algorithms, including full discussion of a fascinating electronics experiment using one such algorithm. There is also some more discussion of computer models on pages 20 and 21 of this thread, including some dedicated evolutionary software called AVIDA.

    Sort of up my street as well, seeing as I just finished a bioinformatics MSc with a project on using various statistical measures of codon bias to try to find gene clusters and highly expreessed genes in bacteria.

    But I have to confess that I have read quite a few of those ID papers now & I still don't quite see what they are worried about. Three quarters of it seems to be more or less common-sense, but in no way in conflict with more generally accepted ideas. And the other quarter looks like handwaving. "I just don't believe it!". They assert that certain biological systems are "irreducibly complex" but have so far offered nbo evidence that they are. (Unless there are other secret publications I haven't come across yet)

    quote:

    Presumably it has to be because a putative designer would have to be someone who would want to design the things they have designed. Though of course that would also apply to a traditional Christian view of creation as well as to ID. (All those mediaeval Catholic proofs of the existence of God for example)

    quote:

    I ask because the more specific a theory is, the greater its predictive power.

    naughty, naughty...


    But more generally, obviously any Christian, or any other kind of theist, has to be deep down inside some sort of creationist, by definition. And if they accept that God is sovereign over the world, and that God has plans which are fulfilled in the world, then they must accept that God in some sense designed the world. But that's not the same as thinking that we can find out things about God by spotting flaws in the design.


    The cheap thing about ID is that it seems to depend on God making mistakes. Back to the God of the Gaps again. That's not as bad as YEC which implies that God tells lies in creation, but it still feels dangerously near the edge of blasphemy to me. (Or at least of a too-small view of God). ID says that the universe that God designed is not capable of bearing the creatures God designed to live in it, so that God has to keep on intervening to fix the flaws in order to keep evolution going.

    Its as if the world has errors in its execution, like parts of an old painting which have been worked over with extra brush-strokes to cover up mistakes, or places where the artist chained their mind, which if examined long enough by a well-trained art critic might reveal information about the painter. Surely God reveals himself in the whole picture, not in any mistakes?

    I salute you for doing some reading on ID ideas for yourself. As evidence for irreducibly complex systems, check out the writings of Michael Behe who is a biochemist, especially Darwin’s Black Box and the subsequent debates. You will probably be able to understand some of the biochemical details much better than I can.

    Nothing naughty about Petaflop’s question at all. If ID ideas are going to win more mainstream acceptance, this is precisely the kind of question that needs to be asked. As I said to Petaflop, Dembski has already asked that question of himself and sketched out an answer.

    I am puzzled as to where you get the notion of “flaws in the design” from? ID claims to be able to detect design, but makes no claims for the optimality of that design or the absence of flaws, however defined.

    Again, I‘m very puzzled by your reference to “mistakes”. I confess I don’t understand you at this point. Please will you expand on your argument here.

    I think you’ve shifted from scientific onto theological ground here. I also think you may be missing the point that the “design inference” of ID theory is being proposed on logical and rational grounds, not theological and revelatory.

    ID theory does not postulate of necessity continuing intervention by the designer. It simply says that we have detected design. When and how that design was implemented is beyond the remit of the theory.

    My computer is operating now because someone designed the computer and someone designed the software. Whoever those people were (and I personally know nothing about them), the continuing operation of my computer no longer depends on their active and continuing intervention, despite the clear evidence of design available to me. The original designers’ work is now finished.

    Mind you, some would say that’s not true - Windows is still full of “flaws”. [Smile]

    Your comment about “God reveals himself in the whole picture” is certainly true from a theological perspective, but again I don’t understand your reference to mistakes. There is no implication in the theory that the detectability of design is any kind of flaw or mistake in the design. Quite the opposite, in fact.

    Here we are back to Gosse and his omphalos (Adam’s navel) again. The YEC world expects us not to accept that the clear evidence of our (scientific) eyes from the natural world. For them that evidence has been superseded by revelation instead.

    By contrast, the ID world trusts the evidence from our (scientific) eyes and draws (scientific) conclusions accordingly. Passing beyond the realm of science to the realm of faith, one is then free to take up any theological position one wishes.

    Dembski and Behe are quite specifically claiming that some biological systems cannot be explained by natural processes (i.e. the ones God created in the first place) and so must have been designed and built in one go (as if God changed his mind and added new bits on)

    But as I said I don't know of any reason to think there are such irreducibly complex systems in biology anyway.

    The problem with the concept of "irreducible complecity" is that it's well nigh impossible to find a conclusive example. You can find examples whereby no currently conceivable mechanism for the development of the system can be determined (and, I'm not sure Behe even manages to find any of them given that AFAIK all the examples he gives have been countered by scientists offering gradual mechanisms how they could have developed) - but how do you prove that no future scientific developments won't find a mechanism whereby those systems could have developed in a gradual manner. Irreducible Complexity is the sort of thing that's liable to have a small number of examples that gradually collapse as science progresses.

    But, I think you've said more or less the same thing earlier on this thread, and suggested that Complex Specific Information is therefore a more useful concept than Irreducible Complexity.

    The claim is more limited than "natural processes" in general. It is about what a specifically Darwinian evolutionary process can or can't accomplish. It leaves open the possibility that "natural processes" contain much more to be discovered. Such new discoveries may well demonstrate how a non-Darwinian evolutionary process constructed an irreducibly complex system.

    (i.e. the ones God created in the first place)
    We're back onto theological ground here. ID does not deny the abilities of presently-known natural processes to drive a limited evolutionary process of some kind. It does however establish the inherent limits of those presently-known processes to construct complex specified information (CSI).

    quote:
    and so must have been designed and built in one go (as if God changed his mind and added new bits on)
    This doesn't follow. In ID theory there is no reason at all for the design and the construction to happen simultaneously. In the real engineeering world temporary states during a project often require as much design input as the final state.

    Similarly in biology, the design may long precede the "construction", i.e. the biological changes that result in "descent with modification". In Davison's form of the ID model, he sees evolution in history as driven by the decompression of existing information within the life-form, long after that information first came into being.

    quote:
    But as I said I don't know of any reason to think there are such irreducibly complex systems in biology anyway.
    The ID poster boy for irreducible complexity (IC) is the bacterial flagellum, although ID theory predicts that IC systems will eventually be found all over the biological world. As Alan Cresswell has remarked, Behe's IC concept has been subject to intense scrutiny and criticism by others. Nevertheless, although it remains very controversial, Behe still stands by his concept.

    In his book No Free Lunch Dembski examines Behe's IC concept in detail and examines the numerous arguments brought against it. He also provides a much tighter definition than the one originally provided by Behe. This is a good example of the responsible internal critique within the scientific ID world.

    I see.

    I think there are a number of related structure's, though, that seem to share common ancestry. Secretion mechanisms, pilae, intracellular ATPase's....... secondly I'm not sure why pick on the flagellum; it strikes me that most organs and most organisms could be described as irreducibly complex on the same basis.

    So the argument doesn't seem different from saying "creation is incredible; there must be a designed" rather than a specific instance of God's footprint.

    I hope you found the links enlightening. I have appreciated your comments to date.

    ID theory of itself does not say anything either way about common ancestry (i.e. "evolution" in its general sense). One is free to make any reaonable deduction from the biochemical and palaeontological evidence.

    Behe, for example, is on record as saying that he accepts the notion of universal common ancestry. Dembski is also very clear that ID theory can live happily with common descent.

    The argument is very focussed - what are the limits (if any) to a specifically Darwinian evolutionary mechanism? Hitherto unknown but more powerful non-Darwinian evolutionary mechanisms are quite consistent with ID theory.

    quote:

    I think the bacterial flagellum is relatively easily understood by non-specialists, hence the frequency with which it appears in ID writing as a poster boy. You are right - ID predicts that irreducible complexity will eventually be found all over the biological world.

    The only significant response that I know about to ID claims about the bacterial flagellum is this article at Talk Reason by Nicholas Matzke. I would appreciate your comments on this article. Dembski replies here.

    I presume you meant to say "there must be a designer".

    This is a somewhat caricatured form of the argument. ID theory provides some rigorous tools to discern the activity of an intelligent agent, but says nothing about who or what that agent is or was. One can see this as "God's footprint" if one wishes, but that is a strictly optional statement of faith that goes beyond the scientific theory.

    Just in order to make our language simpler we can talk about bacteria "intending" to do something, or doing something in order that they achieve some goal. I doubt if anyone at all thinks that that means we assume the bacteria have thoughts or ideas or emotions or intelligence in the way that animals do. Its no different from saying that a plant grows towards the light so that it can photosynthesise. We can even talk about bacteria "choosing" between one life state and another or one behaviour and another. With the possible exception of some aspects of motility effectively all bacterial behaviour is mediated through differential gene expression - a bit more of this protein, a bit less of that. In effect behaviour, gene expression, cell state, life cycle, and phenotype are not separate categories when talking about bacteria.

    So this is much the same argument as the one about whether or not we could describe genes, or at least organisms, as being selfish?

    This is a press release describing a paper which suggests that e-coli bacteria respond to their environment, when their food has run out, by mutating more rapidly. It seems entirely compatible with the theory of evolution, to my untrained eyes.

    I do like the idea that bacteria have a stress protein.

    I'd go further Callan; it supports the theory of evolution. It makes mutation more likely when environment changes.

    However, I think we should be cautious understanding evolution by looking at bacteria. As Ken says, they take up DNA from their neighbours rapidly - as far as I know this kind of horizontal gene transfer doesn't occur in higher organisms.

    I think the argument is similar to selfish gene - but there's an important difference. Gene's are described as selfish because of the selection pressures - and the organism's need to survive/ bear young etc. (I have heard this parodied by describing the "selfish deletion" - which would have RD foaming at every orifice, I'm sure)

    On the other hand, the social intelligence of bacteria is describing a system where simple organisms socially develop a form of complexity in their social behaviour one would not normally expect.

    Not disimilar to ants or bees, come to think of it.

    FS, perhaps the flagellum is a bad example; although non-specialists can easily grasp the idea, they won't know that some of the component parts have uses in other structures.

    That the pilae, for instance, could be fore-runners of the structural element.

    That intracellular ATPases could be fore-runners of part of the motor.

    That one of the secretion mechanisms (type 3, I think) used in other pathways could be a forerunner of the whole setup......

    Whereas with eyes, I think non-specialists (like myself) are more aware of the different kinds of eyes around in animals, worms etc.

    But I'm not clear what these "tools" for demonstrating design are, except to challenge the plausibility of evolutionary mechanisms for various bits of biology.....

    And yes, I did mean designer.

    Yes, I 've heard that viewpoint as well. I've also heard it said that the actual historical evidence shows the type 3 secretory system to have evolved after the bacterial flagellum, and not before.

    Unfortunately, resolving this particular controversy passes into specialist biochemical territory, so I can't comment any further.

    Read this essay on “The Neglected Elements of Scientific Discovery” by “Mike Gene” (a pseudonym) at the TeleoLogic website. He is another professional biochemist and ID theorist. If I recall correctly, he self-identifies as an agnostic.

    The paper you linked to is divisible into two parts. The first, stressing serendipity and personality in the process of scientific discovery is unremarkable. Similar observations can be found, in Peter Medawar's 'The Limits of Science' and 'Pluto's Republic'. Creativity is an important part of the scientific process. Of course, it should be remembered that once one has reached one's conclusions by unorthodox methods they should be replicable by one's more plodding colleagues.

    The second part suggests that the greater the number of researchers engaged in the project of investigating design, the greater the chances of the forces of serendipity and personality hitting upon something to validate the thesis of design. Obviously and unsurprisingly, I disagree with Mr Gene's underlying premise that there is validation to be had but whilst I think his argument is based on a false proposition it is a valid argument. The chances of increasing the sum of human knowledge in any given field are proportionate to the numbers and the skill of the workers in that field. That seems fair enough, nay it seems self-evident.

    But it doesn't, as far as I can see, demonstrate an argument for abandoning methodological naturalism. If we are being undogmatic and purely scientific in assessing evidence for design without being dogmatic about the designer, then we need not assume the scientific method, as it has been generally understood for the last couple of hundred years, is fatally flawed until the evidence starts accumulating. Gene asserts that the scientific community is not open to those aspects of personality and serendipity which validate design.

    It would be idle to deny that most scientists are hostile to design, to that extent he has a point. But most scientists were hostile to evolution in 1857 and to Special Relativity at the beginning of the century. However the data stacked up in such a way that the prevailing consensus changed. Get the data and change the consensus. At its simplest, that is how science progresses. Abandoning methodological naturalism is more akin to changing the consensus on the grounds that it might offer us richer data. One would have to have an inordinately high estimate of the work produced by ID theorists so far, I would have thought, to take such a step.

    Yes, I think so.

    It runs right through biology and has for a century or so. Some biologists will refuse to say that anything has evolved "for" anything. Some very strict biologists will even refuse to say that an organ is "for" something - they would not even say that a leg is for walking or an eye for seeing. But most stick to teleological language because it is easier.

    Yes and no. One of the arguments brought by Darwinists against the concept of irreducible complexity (IC) is the notion of biochemical "scaffolding" - a term clearly borrowed from the world of construction.

    What they mean by this is that the present apparently IC biological system evolved though some complex intermediate states ensuring partial system functionality before the whole system was complete. These intermediate states have now disappeared completely leaving no trace of their existence.

    The argument is that these complex intermediate states were first generated and then dismantled by a purely Darwinian mechanism, leaving a residual biological system in existence. The residual system may appear to be IC in the way that many engineering systems are indeed IC.

    However, on this argument, that appearance of IC is misleading, and any anti-Darwinian deductions from it fallacious, since these deductions do not take into account the intermediate "scaffolding" that was once present but can no longer be seen.

    To understand Dembski's methodology for detecting design one must understand two concepts: the Explanatory Filter (EF) and Complex Specified Information (CSI). Dembski is using these terms in a precise technical manner.

    For now, an old and unfortunately unillustrated article on the Explanatory Filter is here. An article on Complex Specified Information is here.

    Your best bet if you can handle the maths is to read his 2002 book No Free Lunch. In it he also develops his statistical methodology with respect to the bacterial flagellum. The introduction to that book is here.

    Hope that helps for now. I've been studying ID theory, on and off, for over 5 years. It's more complex and subtle than you might think. I don't expect anyone to get on top of it overnight.

    I think that's right. But part of the irreducible complexity argument was that the export and assembly mechanisms were specialized, and could not evolve since there would be nothing for them to do without the flagellae.... and flagellae nothing to evolve for without the export/assembly line.

    So this removes part (if not all) of the irreduciblity.

    “Self evident” in theory, but persuading people to put up the research funding is a large part of the story, as any academic researcher knows. Furthermore, no one is going to want to do any research in this area if it is so controversial that it jeopardises their future prospects.

    A rigorous methodological naturalism in evolutionary science remains a defensible methodology for as long as it continues to provide true insights about the natural world. The proposal to go beyond (not “abandon”) methodological naturalism in this field is partly on the grounds that such a naturalistic methodology has simply failed to deliver any worthwhile scientific fruit, as least as perceived by the ID world.

    Worst of all, such methodological naturalism in evolutionary science has now hardened into a dogmatic philosophical naturalism in some cases, even becoming an unpleasant ideology. Evolutionary science compares unfavourably with the huge progress made in many other areas of science, such as physics and cosmology, where subtle philosophical ideas, including cosmological design, are now being openly discussed in the mainstream.

    quote:
    It would be idle to deny that most scientists are hostile to design, to that extent he has a point.
    The very fact that someone of “Mike Gene’s” intellectual calibre has to shelter behind a pseudonym shows the hostility of the climate in which he is proposing his ideas. I have no idea about his real-life situation, but to me his pseudonym is prima facie evidence of his perception of a threat.

    If you’ve been following Dembski’s salutary experiences at Baylor University (where he used to work as a researcher without tenure), there is every reason to take precautions. Dembski has many intellectual opponents and rather too many political enemies. Fortunately Behe has tenure at his university, but he is not the flavour of the month there, either.

    That is why the ID fraternity are to some extent caught in a “catch 22” situation. To win more mainstream approval they will have to continue to build on their work to date. And to do that they will need to attract the funds and the staff to keep up the research. And for that they will need more mainstream approval. It’s a vicious circle.

    Nobody get's to say. If one publishes enough papers in peer reviewed journals and the evidence stacks up, eventually things shift over. Well argued papers with unpopular ideas do frequently get in high profile places; I remember the chemical basis of homeopathy in Nature.... the case that HIV was spread by vaccination.... deeply unpopular views do get aired. Those two have not stuck - but not because of censorship.

    I think that the case you describe is without evidence. The new guard are just as unkeen on ID as the old.

    I'm still looking at the links you posted .... I've yet to find anything that adds much to the statement "ID = not believing such complexity as creation could be chance". The discussion of probabilities is little more than standard knowledge applied to certain assumptions.... the biology is all well known and not analysed in any particularly new way.....

    I'm with Russ on this, so far.

    In a word, yes. ID arguments take into account the huge advances in mathematical and scientific knowledge since Paley produced his “watch argument”. The whole basis for the argument has moved on substantially.

    Dembski’s work isn’t simply philosophy. His work has a large amount of mathematics and statistics in it. He attempts to provide quantitative tools to discern design.

    In his book No Free Lunch he briefly discusses the challenges to his work from Bayesian statistics and other comparative probability approaches. I think he has discussed this in more mathematical detail in his earlier (and very expensive) CUP monograph The Design Inference.

    quote:

    That’s a fair comment. Dembski’s work has come under heavy and sustained fire from certain quarters. Dembski has responded in depth to his competent critics and still stands by his work. You must make your own mind up.

    No. There’s no attempt to force anyone to accept a viewpoint with which they do not agree. Within evolutionary science a “design” paradigm remains a controversial minority viewpoint at present. This is in marked comparison to, say, cosmology, where “design” seems to be an acceptable mainstream viewpoint.

    Speaking more generally, the ID world would certainly like to have the freedom to accept some form of teleology with respect to evolutionary science. At the moment the reigning naturalistic paradigm rules this completely out of order.

    I've never come across design in any cosmological context - outwith the assorted "creation science" stuff. Certainly not in any mainstream context. Like mdijon, I'd appreciate some expansion on what you mean.

    I thought I would drop by just to see what the fate was of the post I made in Hell and can see that I've nothing unique to contribute. I am completely with ken on EAM and epigenetics: they are both easily explained mechanically as physically based and do not require metaphysical mind for "intent." The whole of "bacterial intelligence," including the appearance of metaphysical intent, can be seen in purely physical terms as well by my eyes. An appearance of "social intelligence" emerges when machines can exchange physical entities, namely signalling compounds, and respond to the exchange. The "learning" and the "memory" they appear to display also have physical roots that don't require metaphysical intent.

    As one looks deeper and deeper into bacteria as machines, it seems to me there is a greater likelihood of proving that we ourselves are in fact dumb machines than there is that bacteria are simple people.

    Seriously. [Paranoid]

    I was using “design” as shorthand to mean “ a more philosophically literate approach to physical science that is willing to consider some form of natural teleology” At the back of my mind when I made that comment was the readiness of some in the cosmological world to acknowledge the Anthropic Principle that was originally proposed in 1973 by cosmologist Brandon Carter.

    It’s my subjective impression that cosmologists consider these ideas to be a respectable opinion even if they are far from being universally accepted by all cosmologists. This contrasts very strongly with evolutionary biology, where ID theory has been vigorously denounced as a viewpoint completely beyond the pale.

    If one looks at the list of fellow in the International Society for Complexity, Information and Design (ISCID) here, one will see that several are astronomers, cosmologists, mathematicians, physicists and scientific philosophers.

    Guillermo Gonzalez is one such fellow. He is an astronomer associated with the making of the film The Privileged Planet. Although I haven’t seen this film, the title does appear to be an echo of what Brandon Carter said about the Anthropic Principle:

    quote:
    "Although our situation is not necessarily central, it is inevitably privileged to some extent". (Carter’s emphasis)
    Another name on the list of fellows, who has already been mentioned above by Callan, is Frank Tipler He is known for his books The Anthropic Cosmological Principle and The Physics of Immortality.

    This thread has already mentioned quantum theory a few times. This theory is well established in physics and has spawned as one possible consequence the “multiverse” hypothesis. There appear to be several different version of this hypothesis.

    What intrigues me in general is that physicists and cosmologists seems able to propose these philosophically nuanced ideas to a mainstream audience without being subsequently denounced vigorously. The ideas in question may be right or wrong – and they can’t all be right! - but cosmology does seem big enough to allow the debate to take place without perceiving a threat to its very existence.

    Of course, the Anthropic Principle ranges from the weak form (we're here to observe the universe, therefore the universe is capable of supporting intelligent life like us. Well, duh) to stronger forms (any universe like ours will result in the development of intelligent life like us) to the very strong (the universe is like it is so that intelligent life would evolve). They're philosophical positions with little in the way of physical predictions (the stronger versions can be used to argue that if intelligent life has to evolve in the universe we have then it most probably has done so on numerous occasions). All but the "well, duh!" weak form are by no means accepted by a large number of cosmologists, and most cosmologists would recognise them for being philosophy beyond the scope of science. And, besides, apart from the strongest form, the Anthropic Principle doesn't imply design or purpose.

    quote:

    And, certainly his Physics of Immortality is about as mainstream in cosmology as Van Daniken's Chariots is in archaeology.

    quote:

    I think the key is the phrase "philosophically nuanced". Cosmologists know that they're dealing with philosophical ideas, and accept that. Something like the multi-verse interpretaion gains a hearing because there isn't a consensus on interpreting quantum mechanics - that the predictions of multi-verse views (to the extent that it makes predictions) and the Copenhagen interpretation (ditto on it making predictions) are identical doesn't help, they basically provide a framework for discussing observations of something inherently beyond normal language to describe.

    I suspect, though I don't hang around evolutionary biologists much, that when a group of biologists go to the bar at conferences they would quite happily discuss philosophical views. It's when what they recognise as being philosophy starts getting passed off as robust science that they get narked.

    I think there is a difference in attitudes between cosmologists and biologists. A crude generalisation may be made that cosmologists are rather happier speculating about the existence of a designer than biologists are. It is worth examining the reason for this.

    One might begin with Simon Conway Morris' recent book 'Life's Solution' in which Morris makes clear his commitment both to Neo-Darwinism and to Christian orthodoxy. Morris' book was respectfully reviewed by scientists from a variety of religious positions - even Dawkins was polite about it which suggests that the science must have been good. It is unusual for a popular work on evolution to suggest that the philosophical implications of evolution may point towards rather than away from a designer - to that extent I agree with FS - but I think Morris got away with it because it is quite clear when he is writing with his scientific hat on, quite clear when he is writing with his philosophical hat on and because he is quite up front about his religious commitments.

    The stock objection to ID, of course, is that it conflates science and metaphysics and that the religious convictions of ID theorists tend to be overt or veiled depending on the exegiencies of the argument. I realise that FS objects strongly to this characterisation but it is a fairly widespread view.

    I think also - for the sake of the argument, or rather for the sake of avoiding an argument, I am not now alluding to ID - evolutionary biologists tend, with justice, to believe that evolution is widely resented and often under attack. From the controversies over Darwin's original thesis, from the various Lamarckian controversies, most notably Lysenkoism even unto Scientific Creationism people have objected to Darwin on ideological grounds. Furthermore within the scientific community there was a bruising battle between the Marxist faction and the sociobiologists in the 1970s. There is therefore, I think it fair to say, an understandable wariness among evolutionary biologists when considering either theological or political implications. A great deal of popular writing on the subject rather regards theology and socialist ideas as mortal competitors with biology rather than as separate disciplines which might be informed by biology. I am afraid that I rather think ID contributes to this unhelpful frame of mind. If exercises like Conway Morris' are rare and if a defensive philosophical naturalism is common it may not be entirely the fault of methodological naturalism.

    Its a while since I read it (though not that log since my copy is still lying around in heaps rather than on a shelf) but it is good.

    Also of course Conway Morris has a big reputation already. Not neccessarily one he wants - he had the strange luck to become well-known (almost famous, or as near to famous as invertebrate palaeontologists ever get) by featuring as the star player in a book by someone else that was putting forward a point of view he deeply disagrees with.

    quote:

    Conway Morris's ideas on that seem (IIRC) more in tune with the anthropic principle than with ID. For him the universe is the kind of place in which creatures like ourselves will evolve by natural means. So there is no fundamental clash between scientific and theological accounts of creation. His line is that if there are aliens they are probably more like us than we might think. If it was possible to rewind the tape and play evolution all over again we'd get a world not very different from the one we are in fact in.

    That's almost the opposite of ID which claims that what we know about the universe doesn't explain life in its own terms, so there must be Something Else that does.

    I think a lot of them would put it more strongly than that. I do hang around in bars with biologists & can therefore humbly report that football, sex, children, politics, beer, sex, and football are more common topics of conversation than philosophy - though we do get round toi that on occasion. Once or twice a term I even get to hang around in bars with palaeontologists, sometimes bincluding a couple of reasonably well known ones. And some of them are very wary of
    mixing it with "Creationists". There are reports and rumours of all sorts of people getting their fingers burned - being quoted out of context as having "disproved" evolution when they did nothing of the sort, or invited to meetings under false pretences and set up to be humiliated. Fine distinctions between YEC & OEC & ID tend not to be made in such gossip. The embedded message - the tradition of the tribe if you like - is that "Creationists" are nasty aggressive small-minded people who will lie and cheat to get their point over, and who put on fake "debates" stage-managed to please the crowd and sideline any scientific evidence.

    It did occur to me that the tolerance his religious beliefs are accorded in some circles stem from his adherence to that more important Darwinian orthodoxy, being Sound On Gould. [Biased]

    I just got back from a conference where I went out to dinner with a couple of other guys. There was three minutes of Reformed Judaism and Unitarianism, but that was it. I can't get people to even talk about the humanities in general, much less philosophy. ID and any kind of creation don't help us with our work; we have to figure out mechanisms. But the proponents use it to level charges of bias, conspiracy, close-mindedness, etc. so it is only a negative and thus people don't like to even hear about it.

    I haven't read Simon Conway Morris's book, but you will find Dembski's review of it here.

    From Dembski's final page:

    quote:
    Ultimately, the problem here is a fundamental tension inherent in theistic evolution. As is characteristic of theistic evolution, Life’s Solution challenges materialism as a metaphysical position but not as a regulative principle for science. In bringing teleology into biology, Conway Morris therefore assumes the role of philosopher and theologian, not of scientist. Thus, however metaphysically pleasing it may be otherwise, the teleology for which Conway Morris argues is not scientifically tractable (if it were, he would be a proponent of intelligent design, which he is not). This is the tension inherent in theistic evolution, namely, trying to marry teleology and science. Theistic evolution does nothing to ease this marriage.
    and his final sentence:

    quote:
    More importantly, those with a stake in integrating faith and learning should be asking themselves why, in the dialogue between science and religion, Life’s Solution is yet another example of religion getting the short end of the stick.
    Perhaps that's why Richard Dawkins was "polite" about this book. [Waterworks] [Smile]

    I've not read the book either. But, that quote seems to totally misunderstand what I'd expect to be Morris' point. I wouldn't expect theistic evolution to attempt to "marry teleology and science", but rather to seperate teleology and science. It's no wonder it doesn't ease the marriage, as it's aim is closer to causing a divorce of the two. Or, at least put the union at some point outwith science - indeed, in the realm "of philosopher and theologian, not of scientist".
     
    Posted by Faithful Sheepdog (# 2305) on :
     
    A further review of Conway Morris's book from the ISCID website is here.

    From the final paragraph:

    quote:
    Theology, Conway Morris argues, will be the lifeline to our study of evolution. He concludes that evolution is congruent with the belief in a Creation in six ways: simplicity, a small ratio of actual to possible possibilities, sensitivity of process and product, the inherency of life, diversity with convergence, and the inevitability of sentience. Convergence is the key to understanding that evolution, despite its tremendous variety, is fraught with direction, or dare say, purpose. It is a bold statement that will undoubtedly receive a strong reaction from the bulk of the evolutionary community. From the ID and creationist communities, Life’s Solution will likely receive a more tepid response. For all of the difficulties, directionality, and “purpose” that evolution entails, ultimately Conway Morris’ views are incongruent with any strong design claim, such as detectability. Evolution, lest we forget, “is the way the world is.”
    So it sounds like Conway Morris is arguing that examples of convergent evolution in particular are evidence of some kind of direction or purpose at work. What do other theistic Darwinian evolutionists make of this?

    Evolutionary biologists do get a bit precious from time to time; I was witnessed a speakers reaction when her terminology was called "Lamarckian" - imagine accusing someone of racism in a social science and policy conference....

    My favourite anti-evolution argument relates to the toxins produced by spore-producing bacteria; which we've discussed previously in purgatory. It's a trivial little point, but very difficult for evolutionary biologists to argue with. And it does produce angry responses.

    I think there is a quasi-religious attitude among some evolutionary biologists; where certain ideas are treated as a religious fundamentalist treats blasphemy.

    But I agree that evolution has been used politically in a way cosmology hasn't, and your argument might explain the sensitivity.... but I'm not sure where the religious fervour of Dawkins et al comes from. In fact, he breaks all the rules you argue (I think rightly) would be rational; making strident claims about the lack of a designer and the evils of religion on the basis of evolutionary science.

    I managed to find a cache of this thread on Google, but it is no longer in Purg.

    Anyway, here's what I found:

The death of the infected human does the bacteria no obvious good either.

    Why should such a sinister mechanism have evolved? I've asked a few evolutionary biologists the question.....and not had anything very convincing as an answer yet.

    I can understand why this question would rankle evolutionary biologists. It contains a crucial misconception, namely that a trait must somehow be useful in order for it to have evolved. In standard-issue evolution, traits do not evolve for a purpose, which is what your question seems to imply, but rather traits simply happen. Now if the trait helps the lifeform out-reproduce others of its species, then it becomes a more common trait in the species. That's natural selection at work. If, however, the trait does not impede the lifeform's reproductive viability, then it gets passed on, even if it isn't necessarily beneficial to the lifeform. The latter can easily be what is happening in the toxic bacteria of which you spoke.

    As I said, I haven’t read Conway Morris’s book, but my impression from reading Dembski’s review is that he takes issue with Conway Morris on strictly scientific grounds. This would be entirely consistent with the flow of Dembski’s argument and the basis of his ID theory.

    One of the fundamental cultural differences between the ID world and the YEC world is that the latter, to a large extent, occupies an uncritical cultural ghetto within a certain strand of the evangelical church. By contrast, the ID world has pitched its scientific ideas to the wider scientific world on their scientific merits alone. That is a much, much tougher assignment.

    quote:

    Please note that the ID world has no argument with the conventional scientific picture of the age of the earth or the basic facts of palaeontology. The very fact that Dembski has read and subsequently written a four-page review of Conway Morris’s book shows a certain level of academic respect for him.

    I think the ID world is very used to “deeply religious orthodox Christians” disagreeing with them, and not just those in the YEC world, either. One of their most vociferous critics in the USA has been the theologian Howard Van Till. This is to misunderstand the argument, which is advanced on its scientific merits alone, and not at all from a theological perspective.

    I think the ID argument is not that “science can resolve metaphysical questions”, but that methodologically naturalistic science may nevertheless point beyond itself to something else – the designer(s) of ID theory. In ID theory, a “design inference” determined on entirely rational grounds certainly does challenge the adequacy of methodological naturalism as a full explanation. Even then, to my eyes, this still leaves many “metaphysical questions” open and unresolved.

    I think Dembski would agree with you that his main intellectual opponent is the “blind watchmaker” thesis of Dawkins et al. His main complaint against Conway Morris seems to be precisely that with respect to evolutionary biology he assumes the role of philosopher and theologian, and not that of scientist. Dembski has proposed his ID theory on rational scientific grounds, and those are the grounds on which it will stand or fall.

    "Useful" strikes me as an adequate word to describe a new trait that gives a selectable advantage, even if it did just "happen" as a result of a fortuitous random mutation.

    Perhaps the selectable advantage in this case is a very short-term one. Then the medium-term disadvantage of the toxin on the bacteria or the long-term death of the host would not matter as far as the spread of a genetic trait is concerned.

    Or maybe the bacteria are intelligent after all and can see some rationality behind the evolution of the toxin, even if so far the explanation has eluded us. [Smile]

    There's a whole subset of evolutionary theory based around the concept of "neutral" evolution associated, I think, with the name of Kimura. In this case new traits that give neither a selectable advantage nor an obvious disadvantage become fixed in a population due to the operation of population genetics.

In talking about the 'meat' of the sandwich he describes it as "popular science writing at its best, and this material is worth the price of the book.", going on to say that Morris describes convergence "at length and with awe". But the bulk of the review basically follows on from the question "what does this all mean? Why is biological convergence important in the wider scheme of things?" ... which is philosophy and theology, not science.

    Selection pressure is responsible for making a trait more common amongst a species but not necessarily for creating that trait in the first place.

    Oh sure; selection hardly causes the mutation in the first place.

    But should the mutation occur, I can't see how it would become a widespread, stable phenomena without selection pressure.

    ...

    Note that this phenomenon is used in forms of "genetic dating" such as the quest for the "mitochondrial Eve". As mitochondria have their own DNA but live in the cytoplasm, they are inherited solely from the mother, with no cross-overs, etc. And they accumulate random mutations in the unimportant parts of the DNA.

    (In the important parts, selection comes into play.)

    This is where I have trouble. I understand science and philosophy to be separate activities.

    Science (i.e. the application of the scientific method) seems to be about gathering evidence, forming hypotheses, and devising experiments to test these hypotheses to destruction.

    Philosophy deals with a wider range of content and is less tied to measurement.

    If a theory has no testable consequences then although it might be an important contribution to philosophy, it isn't (as far as I know) science.

    So when you say (accurately - as far as I can judge) that Dembski's work is philosophy that uses mathematics, then it seems to follow that the grounds that it stands on may well be rational, but they aren't scientific.

    Talking about ID as if it were science comes over as a pretence. Trying to claim the authority of the facts for a personal conviction that in no way arises from the data. Theology seeking the prestige of science.

    Is not the whole thing an attempt to read religious preconceptions into the data - the opposite of scientific objectivity ?

    But if it were conceivable that ID could find hard evidence of design so that the existence of a designer became a "fact" then wouldn't everyone be forced to "agree" ?

    The amount of teleology that the scientist believes in when off-duty is his or her own affair. But seeking to polish up philosophical arguments for the existence of God is not what they should be doing with government research grants to science...

    That evolution by natural selection happens is (as I understand it) demonstrable in the laboratory (eg. in fruit flies). That's science.

    That the processes that are observable in the world today are sufficient to explain how the world came to be as it is (from an earlier state) is a philosophical proposition.

    This is a correct but very theoretical perspective. In practice science also means finding the funding for one’s research projects and then keeping the bosses happy with the results. They may or may not be reasonable people.

    quote:

    Fair comment, but IMO many scientists remain woefully unaware of the philosophy of science. Nuclear safety issues (my own discipline) have forced many engineers to become more philosophically literate. Evolutionary biologists need to do the same.

    quote:

    ID theory does make some predictions and definitely has some testable consequences. Both Dembski and Behe have discussed this in their writings.

    It would be equally true to say that Dembski’s work is mathematics informed by philosophy, but however we describe it, at least we are agreed that his work stands on rational grounds.

    As for whether it is scientific or not, he certainly integrates his ideas on Complex Specified Information (CSI) into the various laws of thermodynamics and then develops his mathematical analyses with respect to certain biological life-forms. That’s good enough for me.

    quote:

    A pretence by whom? Who is pushing the personal convictions without the data? Who is sheltering under the prestige of science? Is this a reference to Richard Dawkins?

    quote:
    Is not the whole thing an attempt to read religious preconceptions into the data - the opposite of scientific objectivity ?
    No. What is automatically religious about a “design inference”? It is something secular humans do all the time. Dembski demonstrates this very clearly.

    If you have the mathematical ability, read Dembski’s 2002 book No Free Lunch. His case is logically developed and very well documented without any reliance on theology. His earlier and hitherto very expensive 1998 book The Design Inference is also coming out in an affordable paperback edition at the end of October.

    quote:
    But if it were conceivable that ID could find hard evidence of design so that the existence of a designer became a "fact" then wouldn't everyone be forced to "agree" ?
    No. Even if there were agreement on the concept of a “design inference” (and at the moment, of course, there isn’t), there would still be nothing definite to identify who or what the designer is. That question would remain open.

    Teleology does not push us automatically in a theistic direction – are you perhaps confusing teleology with theology? They are similar sounding words, but definitely not synonyms.

    Theism (and its corollary, theology) is simply one teleological option among many. The more fundamental question is the nature of nature. Is a compulsory non-teleological scientific paradigm simply prejudging that question on irrational non-scientific grounds?

    quote:
    That evolution by natural selection happens is (as I understand it) demonstrable in the laboratory (eg. in fruit flies). That's science.
    Yes, and ID agrees with this. Don’t confuse the broad fact of evolution (biological descent with modification) with the possible mechanisms that may have caused this change. To my mind that question is still very much open. ID vigorously challenges a Darwinian paradigm as the complete story, but still leaves the door wide open for other more powerful evolutionary mechanisms.

    quote:
    That the processes that are observable in the world today are sufficient to explain how the world came to be as it is (from an earlier state) is a philosophical proposition.
    Completely agree with you here. There is no scientific reason at all for this to be the case, whether in biology or geology.

    quote:

    Yes, again I agree with you, although possibly not in the way you would like. I see the muddying being done by those who are unaware of the philosophical presuppositions implicit in their scientific work. ID theory forces this issue out into the open.

    It's well descrbed that antibiotic resistance genes are lost over time when the antibiotic pressure is removed from the population.

    Why should a large toxin be any different?

    (PS even were it so, it still stikes one as rather odd that this random toxin, with no benefit to the bug, spread horizontally/vertically for no good reason, is also exquisitely finely tuned to take out neurons....)

    Bacteria can't devote resources to useless, sizeable protein synthesis without dividing more slowly. I think this is a fundamental, energy-doesn't-come-for -nothing-sort-of-rule.

    Your second question raises a good point though. I've been simplifying to help my argument; not terribly honest.

    So to come clean, sometimes it is (completely lost that is). There are other occasions when the antibiotic resistant organisms grow as well as the sensitive ones, so the resistance remains after the antibiotic pressure is removed.

    There are even occasions when the resistant bugs are better off; so having evolved, they proceed to take over from the sensitive lot, despite the absence of drug pressure.

    In support of my original argument, though, in all cases this has arisen after a very clear survival advantage (under antibiotic pressure).

    To postulate a benefit to the bug's growth in vitro would be stretching credibility, I think. A benefit in vivo in humans is pretty hard to support as well.

    It's possible the was an in vivo benefit at some stage in another mammal; where the toxin acts differently. It still seems a remarkable act of malevolence on the part of chance .... that the toxin be so finely tuned to killing humans, the environment subtley organised so as to maintain it despite the lack of obvious survival benefit ....

    These amusing sentences opened the second page:

    Something occurred to me the other day.

    If it were possible to set up a "design filter" - an intellectually rigorous method of distinguishing things that were designed from things that were not - would that prove that there are things which God didn't design ? That He is not creator of all ?

    Does the process not require some known-to-be-not-designed-at-all things to contrast with some known-to-be-designed-by-humans things in order to form a basis for such a filter ?

    Just a thought...

    I would also note that pirates are not known for eating lots of pasta. So maybe the increase in pasta consumption is causing the decline in pirates (who are obviously offended that someone would eat a symbolic representation of His Noodly Self). And all the extra water vapour caused by boiling the pasta is what is causing global warming.

    Oh, and quotes from the linked New Scientist article:

    quote:
    Rothschild suggested that Behe’s definition was so loose that astrology would come under this definition as well. He also pointed out that Behe’s definition of theory was almost identical to the NAS’s definition of a hypothesis. Behe agreed with both assertions.

    The exchange prompted laughter from the court, which was packed with local members of the public and the school board.

    Behe maintains that ID is science: “Under my definition, scientific theory is a proposed explanation which points to physical data and logical inferences.”

    Regarding that last one, under my definition Behe is a load his mother should have spat (I feel sorry for anyone who swallows him). Once you start arbitrarily redefining terms to mean what you want them to, you can prove anything.

    And Callan, I'm with you - and would go one step further in agreeing with Behe. Not only am I prepared to conceed that ID is a theory in exactly the same way that Astrology is, I'm prepared to conceed that by standard scientific definitions, ID is a hypothesis.

    There's also a colourful court report in a local newspaper, the York Daily Record.

    It's worth a read, and ends:

    " At one point during Rothschild's cross-examination, the lawyer asked the scientist whether he was co-authoring a book, a follow-up to "Of Pandas and People," with several other intelligent esign moolahs. He said he wasn't.

    The lawyer showed him depositions and reports to the court, quoting two of the other authors as saying he was a co-author.

    Behe said that he wasn't a co-author of the book but that the statements by those guys weren't false. He said one of the authors was "seeing into the future."

    Rothschild asked, "Is seeing into the future one of the powers of the intelligent-design movement?"

    Behe didn't answer.

    He didn't have to.

    Seeing into the future is the province of that other science — you know, astrology."

    Posted by Justinian (# 5357) on :
     
    To be fair to Behe, he may actually be telling the truth on that one. It all depends on what your definition of is is.

    In short, he isn't writing the follow up at this very moment and probably hasn't started yet. The co-authors are seeing into the future because he has signed a contract to do so and will do so even if he hasn't started his part yet. A cheap evasion (unlike Clinton whose counter-question was in the interests of accuracy) but factually true.

    The first part of Behe's cross-examination is now up on http://www2.ncseweb.org/kvd/trans/22051018_day11_pm.pdf and it makes interesting reading - especially for the number of times Behe uses the Humpty Dumpty approach to words that mean what he means, not what everyone else thinks they mean. But he's got no other argument, when presented with statements he's made in the past that go against what he's trying to say now.

    This is perhaps a significant exchange, where Behe is trying to replace 'intelligent design' with 'purposeful arrangement'. I think we may find that this phrase will start to turn up quite a lot as ID itself becomes debased currency - it's certainly there a lot in the transcript.

    Q And zero is the same number of articles in

    A The number of peer-reviewed papers in scientific journals which show that life is composed of molecular machinery that exhibits the purposeful arrangement of parts in detail on term, you know, many many many thousands. There are -- I think there are just one or two that mention intelligent design by name.

    think that I was thinking of something else.

    Q And there are zero articles in peer-reviewed
    scientific journals arguing for the irreducible complexity of complex molecular systems?

    A There are none that use that phrase, but as I
    indicated in my direct testimony, that I regard my paper with Professor David Snoke as to be arguing for the irreducible complexity of things such as complex protein binding sites.

    A Could you repeat the question, I am afraid --

    Q I asked you, is it correct that there are zero
    articles in peer-reviewed scientific journals arguing for the irreducible complexity of complex molecular systems?

    A I would count some other papers as, as impinging on that, on that topic, but I don t -- they certainly don t use the term irreducible complexity.

    -------------------------

    It's interesting that Behe can be so vague on the 'one or two' peer reviewed papers that mention intelligent design - you'd have thought that such landmark publications would have stuck rather more forcefully in the mind. But no, he was 'thinking of something else' -- I wonder which of the two concepts in 'peer review' and 'intelligent design' he might have confused?

    Yes, one peer reviewed ID journal. Though, just how widely they search for peers to do the reviewing would be an interesting question. But, even if all the reviewers are within the ID community that would be a step in the right direction.

    No methods because its a review article I suppose.

    Its not an argument so much as a catalog of famous biologists who said things that can be spun to support ID.

    One noticeable thing is that nearly all the references apart from the ID ones are classic papers, or well-known semi-popular books. In other words this is the work of someone coming at the subject from a textbook overview, rather then something arising from a specialism or research. Not that there's anything wrong about that, maybe we need more overviews.

    For example I recognise & remember reading at least 24 of the papers he cites, not including the ID party line ones, (& probably have read more that I've forgotten) and 9 of the books - I have 7 of them at home.

    "Fundamentalists want to give a scientific meaning to words that had no scientific aim" (Cardinal Paul Poupard, the Pontiffical Council for Culture)

    It's now more than a century since the Vatican would only officially say that science could never contradict a truth found in the Bible.

    Now, it seems that the Vatican has completed its process of accepting Darwinian theory and issued a strong criticism of those who say that Evolutionary Theory and Christianity are mutually exclusive. The two are, according to the latest Catholic statement on the matter, in harmony.

    And it's an interesting way of doing it: not by engaging in the debate on the usual level of looking at examples of evolution in action to demonstrate impossibilities, or by attacking the notion of an "intelligent Creator" - but by simply stating the form, function and content of the Bible.

    Not so much a defense of Darwin as an attack on Fundamentalism.

    You ought to look at www.talkorigins.org as well - if you've got questions about evolution that aren't covered there, I'd be surprised.

    Ross is one of the 'it looks designed and there must be a purpose, so it is and there is' school of creationists - in other words, he starts from the assumption that these things must be true and then applies that filter to everything. From your quote above, it looks like you do, too - which is fine for a personal philosophy but isn't science.

    Don't forget that science has nothing to say about there being a creator (creationists claims to the opposite notwithstanding), beyond the observation that if there is one the methods they use are not inconsistent with a naturalistic analysis of the physical universe.

    Standing in awe is fine, but seeking to find out more is even better. You can even mix the two: the more you find out, the more awesome it all becomes.

    I agree. I think the difficulty comes when there is the appearance of an assertion that "God had nothing to do with it."

    So it makes sense to me that science just reports the facts, and makes no further comment.

    Religion, on the other hand, comes in and adds its own spin to those same facts. Such as "Yes there is evolution just as science indicates. And God is behind all of it."

    Even mixing the two is fine, as long as everyone agrees. For example, in a religious school the automatic assumption is that God is behind everything, so it is expected that science teachers will allude to that idea.

    But mixing the two when there is not agreement about the facts is the trouble we are having now. That's my assessment, anyway.

    There's not much disagreement about the facts among biologists, though - vanishingly small numbers of which see any of the problems raised by ID as being significant.

    The problem is that the ID brigade are insistent that non-naturalistic explanations are a legitimate part of science - see Behe admitting that by his definition of science, astrology would qualify - but they seem not to care that this completely eviscerates the scientific method. People disagree about this fact, certainly!

    There were three possible verdicts. The judge could have ruled that ID wasn't religion, he could have ruled that in this instance the parents were attempting to smuggle in religion or he could have said ID per se is an attempt to smuggle in religion. Number three was what we wanted. Number three was what we got. God bless America!

    The verdict is awash with plums. The judge took time to unladle significant amounts of smackdown on just about everyone involved in the defence, and made his conclusions utterly unambiguous and devastatingly precise. The school board witnesses got a particularly harsh beating -- but that's what happens when you get up on oath and demonstrate that you are clueless and deceitful by lying to the judge about things you don't understand. Behe was put through the cottons-only cycle and hung out to dry, with the judge noting in some detail that none of his claims have stood up to scientific scrutiny. The manifold openly religious statements the DI and its buddies have made in the past were spiffed up and put on display. And the basics of the case - that ID is not science, it is creationist religion - got a fulsome and most welcome logical workout.

    That verdict could have been a posting on the Panda's Thumb by any of the more cogent ID opponents. To see it as a hundred-page plus legal ruling is a thing of joy indeed. I think I'll print a copy out and flick through it from time to time during this season of goodwill.

    What this shows, wonderfully, is that when an intelligent layman, who has a prior commitment only to finding out the truth of the matter, is presented with the scientific evidence for what has been the mainstream scientific model for a century and more, and has that compared with religiously motivated misrepresentation, twisted interpretation and even barefaced lies, it rapidly becomes clear that the scientists are almost certainly rather closer to the truth.

    There is hope. I do hope that this decision will cause many ID proponents, especially in the rank and file, to take stock and ask whether they're being taken for a ride.

    Spot on. The press release really doesn't show much by way of argument about the judgment, and the reasons for it. I am awaiting (keenly) any obs from the White House (as I said in the Hell thread). It really does look like a very wise and very good judgment. And, apparently, the judge is a Republican and Bush appointee.

    I would quite like to hear from Faithful Sheepdog at this point.

    Um, mdijon isn't, AFAIK, Swedenborgian, Kenwritez isn't from London or a librarian (and subscribes to the 9.25 timing of the creation of the world, not the 9.15 or 9.30 [Biased] ) and, sadly, I did not spend the 1980s burning round New York in a Jag, beating up bad guys.

    So I think you can take your conflation with Foaming Draught and advocacy of gay marriage in much the same spirit. Dyfrig was pointedly getting stuff wrong as a JOKE because he'd got the wrong end of the stick viz-a-viz mdijon's remarks.

    So can we close this thread now? ID's had its day in court, Behe and pals had every chance to wheel out their best shots, and an impeccably Republican, Lutherian judge has pronounced in burning letters a hundred feet high that it is warmed-over creationism without a scientific thread to its name (I know we all know that. It just feels so good to type it again).

    There are even signs that some of the big ID guns are wavering over dropping any pretence to the contrary, which would do ID the world of good. It could turn into a ministry and concentrate on preaching, all the while doing some science in the hope of actually producing some data - although I don't think their heart is in that. They don't expect to find anything either.

    Meanwhile, "Darwinism" (more properly, evolutionary theory) goes from strength to strength; barely a week goes by without some very interesting new finding or development related to evolution hitting the mainstream media. This week, a proposal for a new class of antibiotics based on some of the body's own immune system mechanisms has come under fire because of predictions of what would happen if bacteria therefore evolved better defences (conclusion: very scary stuff indeed).

    I think it is safe to conclude that Darwinism is not dead.

    Wouldn't that be like closing a thread on World War II after the Battle of Stalingrad? Or a thread on Marxist-Leninism after 1956? It's fatally wounded but it will struggle on for a bit. People have egos and money invested in this after all. Cynically one might even hope that it keeps going for a few more years. After all, deploying right wing activists and funds in a losing battle keeps them out of mischief on other fronts.

    I don't think they ever did. The whole ID enterprise was based upon bamboozling American culture into believing that evolutionary theory was flawed and inherently anti-Christian. It's preferred weapons were PR, tame journalists and litigation. It chose its field of battle and, ironically and appropriately, it was thwarted in its own chosen arena. As the judge observed, ID was not about promoting critical thinking, it was about formenting a revolution against evolutionary theory. Like plenty of other unsuccessful revolutionaries the Discovery Institute and its fellow travellers mistook their own wishful thinking for a collapsing dynasty.

    Yes, I had a scare when it looked as if my son had acquired such an infection in a puncture wound in his leg. All was well in the end, but there were a lot of worried doctors.

    The frightening part of the idea of using antibiotics based on the human immune system is that any resistant bacteria won't just be safe against the antibiotics, but will also be able to counter our existing defences much better than before. This may not be a good idea.

    quote:


    However, they are still bacteria, just different.

    That's the joy of evolution: everything is something else, just different. Birds are still dinosaurs, just different. We are still fish, just different (really - you can trace the reason we have four limbs positioned where they are to the places on a fish where fins work best). The idea of common descent explains so much that it really can link us and, say, earthworms in a consistent and useful system of definition.

    Enough small changes makes a big change.

    Rex, I don't think it's such a concern. Firslty, the antibiotics you're talking about I guess are based on defensins ..... or perhaps some other part of the innate immune system. This is quite a small part of host defence - and many bacteria have various strategies for getting round different bits of host defence - so resistance here would not be ground breaking.

    Secondly, the bacteria are exposed to these survival pressures anyway - have been for millions of year.... so I doubt anything very scary is in the offing here.

    Famous last words, I know, but then one can always say that.

    Yes it is potentially scary. Our immune system relies on a broad spectrum of defences, so synthesizing one and using it in mega-doses will mean any resistant bacteria will be the only ones left. Then we move onto another defence, and again only the resistant bacteria are left. Eventually you use all the defences of the immune system and have bacteria that are immune to all of them.

    The reason why single vector antibiotics is a bad idea is because it changes the environment that the bacteria live in. Naturally some of the non-resistant bacteria might be better survivors and thus keep the resistant strain in check. So when you wipe them out the resistant strains have no competitors.
     
    Posted by mdijon (# 8520) on :
     
    No, not really.

    Firstly, using bigger doses would generally make resistance less likely to emerge.

    It's chronic low exposures that are dangerous.

    Secondly, most of our immune response is adaptive (antibodies, lymphocyte responses).... and of the innate immunity, a lot depends on neutrophil/polymporphs.... a little bit left over, which is probably very early in evolutionary terms, are the kind of molecules someone might want to use as a blueprint for antibiotic design.

    The dangers described already exist, exist for antibiotic use in general.... and it is acceptable to use single antibiotics in most situations. There are a few well-worked examples where combination therapy prevents resistance (TB, malaria, leprosy) - perhaps the list should be expanded, but using multiple antibiotics without clear rationale will likely increase the spread of resistance, not reduce it.

    The season for peace and goodwill has now past but let me begin by wishing this thread a Happy New Year. Judging by some shipmates’ lack of attention to the facts and the sloppy logic of their arguments, their posts are going to need all the best wishes they can get.

    I have now read the Dover Court judgement in full, twice, all 139 pages of it. For those who haven’t read it – and that appears to include some posters on this thread - the text of the judgment will be found here. All page numbers below relate to this judgment.

    The Dover School Area District Board (“the board”) implemented a new educational policy that effectively mandated the teaching of Intelligent Design (see pages 1 and 2 of the judgment). The plaintiffs considered that this policy violated the first amendment of the US Constitution, “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof”.

    As a result, a court action was raised by a group of concerned parents (Kitzmiller et al) against the new policies of the board. As is now well known, the court found for the plaintiffs, finding that the ID educational policy of the board was unconstitutional and constituted an “establishment of religion” as understood in present American legal terms.

    In the light of these facts, let us examine the various comments made by previous posters commenting on this court judgment.

    quote:
    Callan said:
    Unsurprisingly, the Discovery Institute plan to fight on.

    Is it me or does that press release seem slightly irked in tone?

    Perhaps that irked tone is because Callan has blatantly ignored the facts and thus misrepresented the Discovery Institute’s (DI) position. The DI were not a party to this court case in any shape, size or form, nor were they in a formal legal advisory role to the Dover School Board during the court action. Accordingly they receive only passing mentions in the judgment.

    The DI did have some contact with the Dover School Board in 2004, and did provide some legal advice to them at early stage before the court action became inevitable. The board ignored their advice and implemented its own policy instead. Once the matter came to court, the DI provided the judge with an Amicus Curae brief (Friend of the Court), as did others (page 7)

    The nature of the legal advice provided by the DI is now in the public domain – see here. They have consistently recommended that the teaching of ID ideas should not be mandated by law (as was proposed at Dover).

    In particular, at an early stage they explicitly advised the Dover School Board not to implement the particular policy that they did. This policy required school biology teachers to present ID concepts in the class-room. This policy was compulsory, and not merely concessive. Sadly the board chose to ignore the DI’s advice and ploughed straight ahead into a legal disaster.

    quote:
    Rex Monday said:
    The school board witnesses got a particularly harsh beating -- but that's what happens when you get up on oath and demonstrate that you are clueless and deceitful by lying to the judge about things you don't understand.

    The judgment specifically levels accusations of lying against two named members of the board, Alan Bonsell and William Buckingham. These men clearly played a dominant role in the development of the new policy. This included raising funds in a local church for the purchase of the ID sympathetic textbooks (and then concealing this fact from the court). These men deserve their “harsh beating” in the judgment.

    As for the remaining four members of the board who supported the new policy, the judge does not specifically accuse them of lying, but he certainly does accuse them of gross naivety and of a woeful lack of understanding of the new ID policy that they had voted to implement.

    Personally, I find the judge’s statement here to vindicate some of the comments I have made much earlier on this thread. It is clear to me that many people with essentially YEC views and thinking have adopted the language and vocabulary of ID without understanding the underlying concepts of ID and the fundamental differences from YEC views. This certainly happened at Dover.

    Although the judgment clearly does not express any support for the technical ideas put forward by the expert witnesses for the defence (Behe, Minnich and others) and considers them refuted by others in the scientific community, the judgment vindicates the personal integrity of these expert defence witnesses completely:

    quote:
    From page 137:
    With that said, we do not question that many of the leading advocates of ID have bona fide and deeply held beliefs which drive their scholarly endeavors.

    Karl’s generalized and unrestricted comment about “bare-faced lies” therefore contains the very twisting and misrepresentation that he complains of.

    quote:
    Justinian said:
    Christ is served by exposing the ID lobby for the liars they are - and thereby helping to minimise the future impact of said lobby misusing his name.

    Here the thread reaches a real low point. In the light of the evidence I have presented above regarding the highly restricted nature of the allegations of lying that have emerged from this court case, I consider that Justinian’s generalized and unrestricted remarks about the “ID lobby” being “liars” constitutes a prima facie breach of commandments 1, 2, 3 and possibly 8.

    Please would the host adjudicate on this issue.

    Sadly the “impeccably Republican, Lutherian (sic)” judge does not agree with you about the foreclosing of the discussion.

    quote:
    From page 137:
    Nor do we controvert that ID should continue to be studied, debated, and discussed.

    As for your assertion about “warmed over creationism”, the judgment is singularly disappointing and sorely lacking on this point. Consider the following statement in it:

    quote:
    From page 35:
    The sole argument Defendants made to distinguish creationism from ID was their assertion that the term “creationism” applies only to arguments based on the Book of Genesis, a young earth, and a catastrophic Noaich flood; however, substantial evidence established that this is only one form of creationism, including the chart that was distributed to the Board Curriculum Committee, as will be described below.

    So from this we learn that it is now possible to be a “creationist” without any reference at all to Genesis, Noah and the flood. [Eek!]

    So what is the “substantial evidence” that this is so? The judgment cites an unreferenced document of unknown provenance, and with no other arguments or evidence presented, we learn that the various sub-species of “creationism” are as follows:

    quote:
    From page 106:
    “Young Earth Creationism (Creation Science),” “Progressive Creationism (Old Earth Creation),” “Evolutionary Creation (Theistic Creation),” “Deistic Evolution (Theistic Evolution)”

    Since the document cited linked ID concepts and personalities to Progressive Creationism (Old Earth Creation), that was good enough for the judge to conclude that ID was a sub-species of “creationism”.

    However, on this peculiar logic, those who subscribe to some form of theistic evolution are therefore no less “creationists” that the most ardent members of Answers in Genesis (AiG) and the Institute of Creation Research (ICR).

    These loose statements render the very term “creationist” meaningless and hence useless for enlightening the discussion. As a result the judgment frequently commits the logical fallacy of equivocation. The judge’s sloppy language on this point contrasts strongly with the very carefully documented way in which he has laid out his legal methodology regarding contested constitutional issues.

    quote:
    Callan said:
    It's preferred weapons were PR, tame journalists and litigation.

    On the contrary, the preferred weapons of ID are logic, reason, the laws of science and the known facts of the universe. I am sorry that you are unable to see that.

    quote:
    Callan said:
    It chose its field of battle and, ironically and appropriately, it was thwarted in its own chosen arena.

    Actually no, the Thomas More Law Centre (TMLC) chose to make the mandatory teaching of ID in Dover School into a legal test case over certain American constitutional issues. The Discovery Institute strongly advised both the TMLC and the Dover School Board against doing this, but nevertheless both chose to plough ahead regardless.

    quote:
    Callan said:
    As the judge observed, ID was not about promoting critical thinking, it was about formenting a revolution against evolutionary theory.

    In the context of the judgment, the new ID policy of the Dover School Board had to be understood on the one hand in the light of the board members’ public statements, decision-making processes and policy intentions, and on the other hand in the light of the American constitution.

    Those statements, decisions and intentions were on record, and the record clearly showed that they were heavily religious in tone rather than educational and/or secular. That evidence alone would have been sufficient to have the new policy ruled overtly religious.

    In the light of this it is not surprising that the judge found for the plaintiffs and ruled that the new policy was unconstitutional. I cannot disagree with this part of the judgment at all. On this point it is well documented and well argued.

    However, where the judge has erred very badly indeed IMO is in going beyond the strictly USA constitutional issues of public education policy. He has attempted to use his court judgment to decide highly controverted issues of science and philosophy that have been discussed openly at least since the time of classical Greek thought.

    The very factors that fuel these ongoing controversies are heavily grounded in human self-awareness and human rationality. A constitutional court in Pennsylvania is not going to change any of that.

    Ah, there you are.

    quote:
    Sadly the “impeccably Republican, Lutherian (sic)” judge does not agree with you about the foreclosing of the discussion.

    I merely said what the judge said - that ID is not science, but creationism under a different banner. ID is perfectly at home in philosophy or history of religion classes. Perhaps you could point out where I've said otherwise?

    quote:
    These loose statements render the very term “creationist” meaningless and hence useless for enlightening the discussion. As a result the judgment frequently commits the logical fallacy of equivocation. The judge’s sloppy language on this point contrasts strongly with the very carefully documented way in which he has laid out his legal methodology regarding contested constitutional issues.
    Alas, no. There are plenty of ways to define or categorise different sorts of creationist thought: some are clearly anti-scientific, others coexist well with current science. None is science. That's all Judge Jones is saying. ID is clearly creationism, and is not science - despite the efforts of the IDers to avoid answering any questions that might further define exactly what sort of creationism it is (age of the earth, common descent, nature of fossil hominids, nature of the creator, etc). It's not possible to make ID vacuous enough to let it escape its creationist nature.

    quote:
    On the contrary, the preferred weapons of ID are logic, reason, the laws of science and the known facts of the universe. I am sorry that you are unable to see that.
    Unfortunately, ID is as incompetent to wield those weapons as a toddler is to pilot a nuclear submarine. My chosen weapons to fight crime are a skin-tight leotard and the super-power to turn evil-doers into splendid cream buns. Doesn't help that in my case, one is frankly ridiculous and the other utter fantasy.

    quote:

    Depends. Was it this kind of fishing?

    Anyway, since you're back, a few questions for you. How badly do you think Behe's admissions that ID was no more science than astrology, that there are effectively no peer review publications that demonstrate ID, and that he hasn't actually bothered to keep up with research in those areas which he claims demonstrate ID, have harmed ID? How about the total absence of data produced by the defendents? And how about that absolutely categorical history of revision of the Panda book?

    Reality: ID is creationism. It is not science. We have a hundred-plus page judgement on the back of a 40 day trial, a model of clarity (I'd be tempted to call it crystal clear, but that phrase has a chequered history on this thread) which has seen Dembski close down his blog, Santorum run for the hills and the Disco Institute launch an absolutely unforgivable piece of character assassination on Judge Jones, presumably because they're stuck for anything else to do.

    ID is creationism. There is no science there. Official.

I believe that in the beginning God created the heavens and the earth. I don't, however, consider that those beliefs have any place being taught in a science lesson.

    I also believe that the best description of how God created is found in the theories of mainstream science. Those theories should be taught in science lessons; the only time other things should be taught is in attempting to instill an understanding of how the modern understanding came about (eg: the "plum pudding" model of the atom within the context of teaching how the nuclear model was developed).

    Even if you were being serious, which I doubt, I think that is a forlorn hope. You seem very willing to accept the judgment as it stands without examining the quality of its arguments and the correctness of the facts within it. Do you really think a court in Pennsylvania is going to settle an issue for the rest of the world?

    “Creationism” is a useless word. You are defining it to mean whatever you want it to mean. It adds nothing but fog to the discussion. Even Ken Miller, a witness for the plaintiffs and a committed Darwinian, admitted that as a theistic believer he was a creationist in the broadest sense of the word.

    Don’t misrepresent Behe, he said nothing of the kind. We are going to fall out very fast (again) if you cannot cite witnesses correctly. If I remember correctly, the cross-examination was about Behe’s understanding of the word “theory” and his answer was about how loosely the word is used in the scientific world. On that point he is clearly correct.

    The word “astrology” was brought up by the lawyer cross-examining him. No doubt a loose definition of the word “theory” allows all sorts of things to claim the word as their own, including astrology, but Behe is far from being alone in his loose verbal usage here.

    ID concepts are based on far more than silly semantic games about the word “theory”. This canard is testimony to a verbal trap by a clever lawyer who did not have the means to refute Behe’s scientific position, so attempted to discredit him in other ways.

    quote:
    that there are effectively no peer review publications that demonstrate ID,
    It all depends on that word “effectively”, doesn’t it? Personally I would argue that the AVIDA paper in Nature very clearly demonstrated the truth of certain ID concepts, despite the authors’ intentions to do completely the opposite. A paper doesn’t have to refer explicitly to ID by name to have some bearing on this subject.

    In plain terms the judgment is factually incorrect about the lack of peer-reviewed publications discussing ID concepts. This list at the Discovery Institute sets the record straight.

    Perhaps you can tell me who peer-reviewed Darwin’s Origin of Species? Many new scientific ideas are found in books before they make their way into the peer-reviewed journals. In any event, there is a case that the peer-reviewing process establishes an orthodoxy, stifles dissent, and actually acts against genuine scientific discoveries.

    quote:
    and that he hasn't actually bothered to keep up with research in those areas which he claims demonstrate ID,
    Now you’re making very personal comment about Michael Behe. How do you know that he hasn’t kept up with research in ID related areas? Have you seen an audit of the books and journal papers he has read and the conferences he has attended? Are you personally competent to comment on what counts as cutting edge biochemical research?

    For the record Behe’s book still sells very well and I believe he is presently working on a follow-up. Given his current high profile name and establishment disfavour, I suspect that he has his finger well on top of his subject. He would be a fool to do otherwise.

    quote:
    have harmed ID?
    The court judgment has clearly stopped the Dover School Board in their tracks, but I don’t see that as a bad thing. Frankly, understanding ID properly requires much more mathematics and philosophy that most 15 year olds are likely to have, but the good news is that college students in America have an ever increasing interest in ID issues.

    So, I seriously don’t think this court decision has harmed ID at all. There is no such thing as bad publicity. Judge Jones decides the law in Pennsylvania and some will be happy to rely on him for their opinions on contested scientific matters. Fortunately, many others will investigate these matters for themselves and then make their own minds up.

    quote:
    How about the total absence of data produced by the defendents?
    At heart ID is the rational and empirical detection by humanity of the action of an intelligent agent. Since you do not accept there is any validity or merit to ID ideas at all, there is no possible biological data that could be produced that would keep you satisfied. So your point here is a red herring.

    The case for the defence was managed by the Thomas More Law Centre (TMLC). Some of the big names associated with the Discovery Institute who were slated to appear as witnesses (Dembski, Meyer, Berlinski et al) withdrew at an earlier stage because they lost faith in the way the TMLC was conducting the case. So perhaps also that defence was not well conducted.

    quote:
    And how about that absolutely categorical history of revision of the Panda book?
    The publishers of that book were forbidden by the judge from giving evidence in the court, so the full story could not be given. The editorial history reflects the fact that the USA Supreme Court (I think) clearly defined legally what it meant by “creation science” some 20 years ago or so. The book was edited at the time to reflect the fact that it took a different stance from that considered as “creation science” by the Supreme Court.

    It is a normal practice when considering the history of a document to see an editorial change as reflecting a conscious change of meaning and content. That is how lawyers and judges look at the final form of legislation in the light of earlier drafts. Those editorial changes enable them to be clearer about the intentions of the law makers, especially on matters on which the final draft may be ambiguous.

    Sadly, the judgment does not deserve the high accolades you give it, but I do think the judge reached the right verdict in respect of Dover School Board’s mistaken attempt to mandate the teaching of ID. Given the hotly controversial nature of the subject and the widespread misunderstanding about what it involves, a policy of compulsion was a foolish mistake in political terms.

    quote:
    which has seen Dembski close down his blog,
    You are seeing conspiracy theories everywhere. So, tell me, have you worked out who shot Kennedy yet? And have you seen Elvis lately? [Smile]

    Dembski’s main scientific work is at his Design Inference Website which is staying open. He personally will still be blogging occasionally at Intelligent Design the Future. He has already written a string of books and his peer-reviewed opus magnum, The Design Inference, is just now out in an affordable paperback. I don’t think he will be going away just yet.

    quote:
    Santorum run for the hills
    Who is he? I actually know nothing about the man. For all I know he may be a person of integrity and honour hounded out by uncouth and violent enemies.

    quote:

    I believe that the Discovery Institute described him as an “activist judge” with “delusions of grandeur”. In my opinion that was a fair comment based on the extent to which the judge went well past what was legally necessary to settle the particular constitutional issue in Dover, based on his excessive confidence as expressed below:

    quote:
    From page 63 of the judgment
    …the Court is confident that no other tribunal in the United States is in a better position than are we to traipse into this controversial area.

    I have to admire the judge’s chutzpah, if not his discretion. Only fools rush in where angels fear to tread. However, I think he made the right basic call in his judgement with respect to the Dover School Board, although his judgment also makes several errors of fact and commits numerous logical fallacies. If this case should ever go to appeal (which looks unlikely at present), he will be vulnerable on those grounds.

    quote:
    ID is creationism. There is no science there. Official.
    Actually the judgment only applies to Pennsylvania, even within the USA. Here in the UK I prefer to do my own thinking. I can afford not to worry about American constitutional niceties and I’ll make my own mind up about what is science or not.

    I have grown to admire your tenacity. While I understand your defence of the DI, I would also be grateful for your opinion on the those parts of the judgment (bottom p68- top of p69) which refer to the DI and the Wedge Document. Has the DI commented on the accuracy or otherwise of that part of the judgment? We discussed the significance of the Wedge Document earlier in the thread and here is an earlier comment by me. The damage is now obvious.

    Here is a key quote from the judgement
    quote:
    ..the Wedge Document states in its “Five Year Strategic Plan Summary” that the IDM’s goal is to replace science as currently practiced with “theistic and Christian science”. (my explanation; IDM = Intelligent Design Movement)
    I reiterate my earlier view that you (and maybe other proponents of ID) have underestimated the damaging effect of the Wedge Document and its "ad hominem" aggression. Until this aim is repudiated, proponents of ID will be hamstrung by it. In fact, given your tenacity, I would have thought it was now in your interests to repudiate it. What do you say?

    I've read the judgement through a few times now. The quality of the arguments and the correctness of the facts seem pretty good to me, and the writing has an exceptional clarity by American legal standards (I've seen some stinkers).

    quote:
    “Creationism” is a useless word. You are defining it to mean whatever you want it to mean.

    Nonsense. Creationism means a belief that the universe was created by an external act rather than coming to be by itself. That's pretty unambiguous, wouldn't you say?

    quote:
    Even Ken Miller, a witness for the plaintiffs and a committed Darwinian, admitted that as a theistic believer he was a creationist in the broadest sense of the word.

    Absolutely. And creationism, no matter what flavour, is not science and is not to be taught in science classes. ID is creationism, therefore it is not science. That seems very clear to me, and to the judge, and to nearly everyone (Christian and not) with whom I've talked about the decision.

    The logical reasons why ID is not creationism were presented during the trial. They were found to be utterly inadequate - and as a by-product, thoroughly documented as such.

    quote:
    Don’t misrepresent Behe, he said nothing of the kind. We are going to fall out very fast (again) if you cannot cite witnesses correctly. If I remember correctly, the cross-examination was about Behe’s understanding of the word “theory” and his answer was about how loosely the word is used in the scientific world.

    There's no need to misrepresent Behe. He was talking about his own use of the word theory -- which is not the way it's used in mainstream science -- and admitted that under his own definition astrology would be as rigorous as ID. From the New Scientist report of that part of the trial:

    quote:
    Because ID has been rejected by virtually every scientist and science organisation, and has never once passed the muster of a peer-reviewed journal paper, Behe admitted that the controversial theory would not be included in the NAS definition. “I can’t point to an external community that would agree that this was well substantiated,” he said.

    Behe said he had come up with his own “broader” definition of a theory, claiming that this more accurately describes the way theories are actually used by scientists. “The word is used a lot more loosely than the NAS defined it,” he says.
    Hypothesis or theory?

    Rothschild [prosecuting - RG] suggested that Behe’s definition was so loose that astrology would come under this definition as well. He also pointed out that Behe’s definition of theory was almost identical to the NAS’s definition of a hypothesis. Behe agreed with both assertions.

    We're dealing with whether ID is science or not. Behe's choice of definitions that lie outside normal scientific use is important. Likewise, Behe's inability to name a single peer-reviewed paper in court -- while being encouraged to do so -- is important.


    quote:
    ID concepts are based on far more than silly semantic games about the word “theory”. This canard is testimony to a verbal trap by a clever lawyer who did not have the means to refute Behe’s scientific position, so attempted to discredit him in other ways.
    Behe had plenty of opportunity to point this out. He had a defence lawyer to help him. His science didn't stand up to scrutiny. At some point, you'll have to accept that. And if you read the court transcripts, you'll have to accept that the prosecution was entirely up to speed with the science.


    quote:
    Personally I would argue that the AVIDA paper in Nature very clearly demonstrated the truth of certain ID concepts, despite the authors’ intentions to do completely the opposite. A paper doesn’t have to refer explicitly to ID by name to have some bearing on this subject.
    I never could understand how you could impute intelligent design to a mechanistic analogy of biological evolution - nor why if that was the case, you had any problem with evolution as it stands.

    quote:
    In plain terms the judgment is factually incorrect about the lack of peer-reviewed publications discussing ID concepts. This list at the Discovery Institute sets the record straight.

    That list is not what it purports to be - which is why, I'll wager, it was never raised or tested in court. How can the Disco Institute claim that inclusion of an article in a book edited by Dembski qualifies something to the equivalent status of peer review, for example? And as has been pointed out elsewhere, even allowing for the most generous analysis of the DI's claims for that list, the number of papers represented over the time covered would shame even the smallest research department at a rural university. In any terms, even the most generous, it is scientifically negligable - and if you ask for the same standards as you'd expect from someone composing a CV in support of a job application at a university, it's negligable in every respect.

    As I said, Behe was unable to name a single paper to the court which qualified as a properly peer reviewed publication in support of ID.

    There is only one conclusion.

    quote:


    Perhaps you can tell me who peer-reviewed Darwin’s Origin of Species? Many new scientific ideas are found in books before they make their way into the peer-reviewed journals.

    quote:
    Now you’re making very personal comment about Michael Behe. How do you know that he hasn’t kept up with research in ID related areas?
    I recommend a look at the transcript of the trial, especially Day 12, where Behe says that he hasn't read any of really quite a long list of publications about the evolution of the immune system because he doesn't need to. I won't paraphrase him exactly, because it's quite an involved Q&A (and shows that the plantiff's lawyer is entirely in command of his brief, btw), but Behe's saying that he's so sure that his conditions for evolution cannot be met that there's no point in him reading the literature.

    This is not good science.

    quote:
    Given his current high profile name and establishment disfavour, I suspect that he has his finger well on top of his subject. He would be a fool to do otherwise.
    He certainly looked foolish in the courtroom.

    It would have to be spectacularly badly conducted if a key witness was unable to provide data, papers or scientific argument after all these years of the DI claiming the opposite.

    quote:
    The publishers of that book were forbidden by the judge from giving evidence in the court, so the full story could not be given.
    I think you'll find both the defence and the plantiffs opposed the publishers' motion for intervention, which was in any case made at a very late stage and would have had considerable procedural implications. It's not a matter of the judge forbidding this, it's him deciding not to make an exceptional case of admitting them against the wishes of all other parties. In any case, the documents were merely evidence, and the publishers were not parties to the case, and the defence was free to present whatever it liked to explain that evidence.

    No, I was referring to John West's deliberate misquoting of Jones' description of work he did earlier in his career to save a man from Death Row. As far as I know, Jones has no record of judicial activism, and this was an attempt to misrepresent him in order to generate one.

    Nonsense. Merely disagreeing with you is not committing a logical fallacy! Given that the court can only decide on the evidence presented to it during the trial, which errors of fact and logic are in the decision? So far, you've just provided excuses from outside the trial - ones which, if the judge had included them in his consideration, would certainly have raised doubts about his conduct.

The damage is now obvious.

    I beg to disagree that the “damage is obvious” What is obvious to me from pages 68 and 69 is the court’s very sloppy treatment of the Discovery Institute (DI). The DI were not a party to this case and were not required or invited to give evidence in court.

    In particular, they were not asked to explain what they meant by the Wedge Document, or even whether it represented current DI policy, since it is now in fact out-of-date. As a result of this the judge has sadly bought into the gross misrepresentations of certain vested interests.

    Compare the following nuanced sentence from the Wedge Document:

    quote:
    Design theory promises to reverse the stifling dominance of the materialist worldview, and to replace it with a science consonant with Christian and theistic convictions.
    with the crude interpretive gloss that the judge has given it at the top of page 69:

    quote:
    The IDM’s goal is to replace science as currently practiced with “theistic and Christian Science”.
    The judge does at least manage to get the quote correct in the footnote to page 69, but the crude gloss remains in the main text. Consider also the judge’s next statement near the top of page 69:

    quote:
    The IDM [Intelligent Design Movement] seeks nothing less than a complete scientific revolution in which ID will supplant evolutionary theory.
    where the word “complete” will not be found in the Wedge Document, and again the whole sentence is a crude interpretive gloss on a much more nuanced statement from the DI.

    Notice also that the judge confusingly conflates the DI with something called the Intelligent Design Movement. At this point in the judgment he is factually incorrect again – ID predates the DI, and has always been bigger than the DI.

    In these comments the judge ceases to be a judge and becomes a political commentator instead. His comments also reveal his limited knowledge of the philosophy of science. That may of course reflect the inadequacy of the evidence given in the court, something that has already been mentioned on this thread.

    In the history of the philosophy of science, the phrase “scientific revolution” has been used by some of the most respected writers such as Thomas Kuhn (“The Structure of Scientific Revolutions” is his best known book, which popularised the phrase “paradigm shift”, I think).

    So, in using the words “scientific revolution” there are absolutely no implications of violent political upheavals or the forcible establishment of a right-wing theocracy or any other improper behaviour. There is nothing in the Wedge Document at all to suggest that. It is a figment of some people’s paranoid imaginations.

    I have noted your viewpoint but I remain unchanged in mine that there is nothing in the Wedge Document that I need to repudiate. As the Wedge Document itself says:

    quote:
    Without solid scholarship, research and argument, the project would be just another attempt to indoctrinate instead of persuade.
    The Wedge Document therefore proposed in a democratic and pluralistic USA context a program of reasoned persuasion by means of scholarly research, journal articles, conference papers, popular books and media appearances. The fact that some people find this program such a frightening thought says a lot more about them than it does about the DI.

    You may also want to ask yourself why none of the DI’s detractors has ever contacted the DI to ascertain if their views and intentions are being correctly understood. This thread has already seen numerous factual inaccuracies about the DI by people who should know better. There is absolutely no excuse for the foolish hysteria that the Internet conspiracy theorists have whipped up.

    The DI has now itself commented extensively on the Wedge Document here. This document was only posted on December 19th 2005, so it is very new. In it they explain the history, purpose and meaning of the Wedge Document. It turns out it was originally a fund-raising proposal that dates from 1999 or earlier, so I was not far off when I called it a Public Relations Strategy.

    I suggest that you read the DI’s explanations and then consider whether they and the Wedge Document have been fairly represented in the court judgment or in any of these shipboard discussions.

    That’s not how the word is defined in the dictionaries, or used in the popular media, or even at the Panda’s Thumb blog. I stand by my view that it is an equivocal term often used with pejorative overtones, and that it serves to obfuscate rather than clarify.

    That is why ID opponents are so desperate to paint ID supporters as “creationists”. It is a ruse to avoid discussing the substantive issue at the heart of this debate. It also deflects attention away from the philosophical outlook always implicit (and sometimes all-too-explicit) in ID opponents’ views.

    A good exercise for you would be to present your ideas and views without once using the word “creationist” and “creationism”. That would force you to think about what it is you are really trying to say in language that is clear, unequivocal and uncontested.

    The trial was actually about the constitutionality of the actions of the Dover School Board. A Pennsylvania court can rule authoritatively on the American constitution on Pennsylvania. It cannot be binding on anyone else.

    Here I disagree with you completely. The word “theory” has all sorts of usages among scientists, ranging from the icily precise to the hopelessly fuzzy. But semantic quibbles like this are the stuff of cynical lawyers out to make disguised ad hominem attacks.

    quote:
    and admitted that under his own definition astrology would be as rigorous as ID. From the New Scientist report of that part of the trial:
    I suggest you concentrate on Behe’s technical ideas and stop worrying about how he uses the word “theory”. There is a whole class of mathematical functions that is perfect for describing Behe’s ideas in a mathematical form. I suggest you do some research on Heaviside Step Functions. Have you ever heard of them?

    quote:
    Because ID has been rejected by virtually every scientist and science organisation, and has never once passed the muster of a peer-reviewed journal paper, Behe admitted that the controversial theory would not be included in the NAS definition. “I can’t point to an external community that would agree that this was well substantiated,” he said.
    Take careful note of that word “virtually”. There is no argument here, only political cheer-leading. Of course ID is a minority viewpoint at present in the west, although whether that would be the case globally is a good question. The big question is, will it be a minority viewpoint in the west of the future?

    I note that you also repeat a factual inaccuracy again about peer-reviewed journal articles. Meyer’s paper on the “Origins of Biological Information and the Higher Taxonomic Categories” was published in the Proceedings of the Biological Society of Washington and was fully peer-reviewed.

    Perhaps you would like to tell this thread about the subsequent harassment, bullying and abuse directed at the editor of that journal? And perhaps you would like to speculate about how that example may have influenced other journal editors considering articles from ID-sympathetic sources?

    quote:
    Behe said he had come up with his own “broader” definition of a theory, claiming that this more accurately describes the way theories are actually used by scientists. “The word is used a lot more loosely than the NAS defined it,” he says.
    Hypothesis or theory?

    Who appointed the NAS semantic guardians of the English scientific vocabulary? I think it would be very interesting to compare their formulations with those of other writers from an earlier historical period. I would be surprised if their views stand up on a historical analysis.

    quote:
    Rothschild [prosecuting - RG] suggested that Behe’s definition was so loose that astrology would come under this definition as well. He also pointed out that Behe’s definition of theory was almost identical to the NAS’s definition of a hypothesis. Behe agreed with both assertions.
    This trial did not have a prosecutor since it was not a criminal court prosecution, but a civil court action about American constitutional law. The word you are looking for is “plaintiff’s lawyer”.

    quote:
    We're dealing with whether ID is science or not. Behe's choice of definitions that lie outside normal scientific use is important. Likewise, Behe's inability to name a single peer-reviewed paper in court -- while being encouraged to do so -- is important.
    Behe’s language semantics in relation to the wider scientific world was not the subject of the trial. That is an irrelevant smoke-screen. What matters is the content of his scientific ideas.

    quote:
    Behe had plenty of opportunity to point this out. He had a defence lawyer to help him. His science didn't stand up to scrutiny. At some point, you'll have to accept that. And if you read the court transcripts, you'll have to accept that the prosecution was entirely up to speed with the science.
    Actually, I prefer to spend my time reading the writings of the original authors rather than court transcripts involving semantic games played by cynical lawyers. I am quite confident in my own ability to judge whether Behe’s science “stands up to scrutiny”.

    quote:
    I never could understand how you could impute intelligent design to a mechanistic analogy of biological evolution - nor why if that was the case, you had any problem with evolution as it stands.
    The fact that you do not understand my point about Avida is very revealing indeed, since the whole program is awash with intelligent intervention from start to finish. I’m just amazed that so many people can’t see it.

    You are also using the word evolution in a very equivocal sense (again). With such fatal imprecision in your language, I am not surprised that you do not understand ID concepts at all or the perspective of ID sympathisers such as myself.

    quote:
    That list is not what it purports to be - which is why, I'll wager, it was never raised or tested in court. How can the Disco Institute claim that inclusion of an article in a book edited by Dembski qualifies something to the equivalent status of peer review, for example?
    I suggest that you get your facts straight. Your inability to do this fatally undermines your credibility and renders any subsequent opinions worthless.

    Dembski’s book The Design Inference (based on his PhD thesis) went through a comprehensive peer review process at Cambridge University Press (CUP). I suggest you read his own account of the peer review process involved here (scroll down to section 2).

    Dembski even volunteers the fact that of the three peer-reviewers acting for CUP, two supported publication and one did not. How much more honesty do you want?

    quote:
    And as has been pointed out elsewhere, even allowing for the most generous analysis of the DI's claims for that list, the number of papers represented over the time covered would shame even the smallest research department at a rural university. In any terms, even the most generous, it is scientifically negligable - and if you ask for the same standards as you'd expect from someone composing a CV in support of a job application at a university, it's negligable in every respect.
    Here you have shifted your ground markedly. Previously you were complaining that there were no peer-reviewed writings. Now that you have been given evidence that are in fact some, you then complain that there are not enough. This is just irrelevant whinging.

    quote:
    As I said, Behe was unable to name a single paper to the court which qualified as a properly peer reviewed publication in support of ID.
    That may be true in the context of Behe’s own specialist interests, although as we now know it is not true when considering science overall. I suggest that you contact Michael Behe and put that question to him again without the constraints of courtroom theatrics. He may have had a chance to reflect further on it. His forthcoming follow-up book may also shed some light on this.

    quote:
    There is only one conclusion.
    I am happy to do my own thinking and I reach my own conclusions.

    quote:
    Which ones, in particular?
    See this paper at ISCID by Frank Tipler for further discussion on this point.

    quote:
    I recommend a look at the transcript of the trial, especially Day 12, where Behe says that he hasn't read any of really quite a long list of publications about the evolution of the immune system because he doesn't need to. I won't paraphrase him exactly, because it's quite an involved Q&A (and shows that the plantiff's lawyer is entirely in command of his brief, btw), but Behe's saying that he's so sure that his conditions for evolution cannot be met that there's no point in him reading the literature.
    You presuppose that the publications in question are relevant to the questions raised against Behe’s scientific ideas. Nobody can possibly read everything even in one’s own technical field. He is perfectly in order to assign priorities to his reading as he thinks fit.

    quote:
    This is not good science.
    That is a nonsensical statement and does not logically follow from any evidence cited in respect to Behe. You are simply indulging in the behaviour you have complained about in others, namely character assassination.

    quote:
    He certainly looked foolish in the courtroom.
    That’s your opinion. I do not share it.

    quote:
    There most certainly is such a thing as bad publicity!
    Perhaps, but in respect of ID concepts and ideas this trial has no doubt piqued many people’s curiosity. Now that the trial has finished perhaps some people will wish to examine these concepts and ideas for themselves. That can only be a good thing.

    quote:
    If it's science, then the data can be presented and independently verified. There is no data. There are no papers. There is no science.
    You forgot to add that ID is a right-wing conspiracy to establish a theocracy. [Smile]

    quote:
    It would have to be spectacularly badly conducted if a key witness was unable to provide data, papers or scientific argument after all these years of the DI claiming the opposite.
    On that point you may actually be correct. I think there ought to be a query against the competence of the defence conduct. The issues of interest to the TMLC are very different to those of the DI.

    quote:
    I think you'll find both the defence and the plantiffs opposed the publishers' motion for intervention, which was in any case made at a very late stage and would have had considerable procedural implications. It's not a matter of the judge forbidding this, it's him deciding not to make an exceptional case of admitting them against the wishes of all other parties. In any case, the documents were merely evidence, and the publishers were not parties to the case, and the defence was free to present whatever it liked to explain that evidence.
    You are right about the procedural issues relating to the trial, but this may be an example of the poor defence strategy employed by the TMLC. Given the central role of the book in the Dover School ID policy and the subsequent judgment, court evidence from the publishers would have been very useful indeed.

    quote:
    Really? Which parts of the book differed from that, then?
    I haven’t read that particular book so I cannot say. Remember it is aimed at children, not adults.

    quote:
    It held up ID to the most rigorous examination of the facts that it has been exposed to. That's a good thing, even if you feel it was a mistake.
    The mistake I referred to was made by the Dover School Board in implementing a compulsory educational policy about a controversial subject that they did not understand. They ignored the advice from the DI and ploughed ahead to an expensive legal disaster.

    A court of law is not the place to establish hotly contested issues of science and philosophy, especially with cynical lawyers playing semantic games. You are quite mistaken if you think that Judge Jones has settled this issue once and for all.

    quote:
    Peer reviewed, eh? Tell me, what is the mechanism for peer review of a book? Which organisation was responsible?
    With this kind of comment you just demonstrate that you haven’t done your homework and you lose all credibility. Full details are in the link I posted earlier.

    quote:
    No, I was referring to John West's deliberate misquoting of Jones' description of work he did earlier in his career to save a man from Death Row. As far as I know, Jones has no record of judicial activism, and this was an attempt to misrepresent him in order to generate one.
    As far as this thread is concerned, I’m only interested in the content of the judge’s written judgment. All these other issues from his past professional and private life are irrelevant. Whether he is “impeccably conservative [and] Lutherian” (your words) or otherwise is not the issue.

    quote:
    Nonsense. Merely disagreeing with you is not committing a logical fallacy! Given that the court can only decide on the evidence presented to it during the trial, which errors of fact and logic are in the decision? So far, you've just provided excuses from outside the trial - ones which, if the judge had included them in his consideration, would certainly have raised doubts about his conduct.
    I never claimed that disagreeing me constitutes a logical fallacy. A logical fallacy refers to the flow of the argument and the logical basis on which a conclusion is reached. Note that an illogical argument may still reach a correct conclusion, even if the argument is faulty.

    It is on that basis that I think the judge made the right decision in respect of Dover School Board, even if some of his argument is questionable or downright faulty. I have already mentioned some errors of fact in the judgment.

    As for errors of logic, the fallacy of equivocation is all over the judgment, joined on pages 8 and 9 with have a classic example of the fallacy of the excluded middle, as follows:

    Fundamentalist creationists oppose “evolution” (meaning of evolution completely undefined at this point in the judgment).

    IDists oppose “evolution” (fallacy of equivocation enables the judge to make another factual incorrectness – actually ID per se only opposes unteleological concepts of evolution aka the Blind Watchmaker hypothesis of Dawkins et al. Behe accepts common descent as a description of natural history.)

    Therefore IDists are fundamentalist creationists.

    As an argument it is stunningly inadequate and an exceedingly unfortunate start to the judgment. Fortunately the parts dealing with the specific actions of the Dover School Board are much better.

    There's really no cause to criticise for going out of scope a very good and well-respected judge who did a good job in a difficult situation just because you disagree with his conclusions on so-called Intelligent Design theory. And I think he pretty much had to rule on the scientific aspects, given the case and the way it was presented.

    In this case, the fact that the (former) school board members were recognized clearly as pushing ID for religious reasons, and lying about it (nice Christian witness there), was what I think really pissed off the judge and rightly so.

    It is an additional benefit that Behe was shown to be the nonsense peddler he is. Generally debates like this do better out of court, but I think there was a benefit conferred this time in having them on the stand. I'm a huge fan of free speech for this reason.

    I generally stay away from this thread, because the issue is so annoying that even engaging in the debate skews my blood pressure, mostly because of FS's persistent and inexplicable repeated endorsement of "scientists" who, however well intentioned they may be, seem not remotely to understand what science demands. But I can't let you be horrible about the judge in this case without commenting.

    Sorry -- just read back and Rex Monday said it much better. But I thought it was an extraordinarily well-reasoned decision and one that will, thanks be to God, as a consequence be widely used in other courts where this issue arises.

    Anyway, I have no problem with debate about whether God or the Flying Spaghetti Monster drives evolutionary change in philosophy or religion classes, where it belongs.

    I've just read the judgment, and it certainly looks to me to me an excellent one. The Judge sets out very clearly the actual and intended meaning of the proposed ID disclaimer and leaves very little room for argument that the purpose here was wholly religious and not scientific.

    What I'm less convinced about is whether a disguised religious motivation is always and necesarily going to be part of the ID movement. Doesn't the suggestion that it is by nature (not just in this particular cultural manifestation) a form of creationism imply that the question "was this designed?" applied to a living thing is forever outside the realm of science?

    I can see that for an organism, like, for example, man, where a scientific explanation is offered of its origin, the claim that "it may look like that, but in fact the FSM created it" is untestable and thus unscientific, but I don't think it follows that all claims of design are necessarily unscientific. If, for example, we were aware of the possible existence of an advanced (human or alien) bio-engineering technology, and discovered a new species in an area that might have been exposed to such technology, wouldn't it be legitimate, in principle, to ask whether the thing evolved or was 'created'? If ID sets out and explores the sort of things we should look for to test a design hypothesis in such a case, isn't it possible for ID to be valid science?

If ID sets out and explores the sort of things we should look for to test a design hypothesis in such a case, isn't it possible for ID to be valid science?

    Design is already part of science - archaeology wouldn't get very far if it couldn't tell a designed item from a natural one! Likewise, forensic science has to tell natural events from artificial ones, accidents from design. There's nothing inherently unscientific in any of this - and in the future, areas such as SETI (Search for Extra Terrestrial Intelligence) hope to be able to extend such ideas in further fruitful ways. I dare say that we'll have to deal with the problem of deciding whether a particular pathogen was designed or naturally evolved too, which won't be fun.

    Where ID stands apart is in having no basis for its claims that can be demonstrated. Those claims are that currently known biological systems are so complex that they could not have evolved through natural selection, and that this means that they must have been the creation of an intelligent designer.

    The problem with the first part is that evolutionary scientists cannot follow the logic nor see the evidence that the IDers claim to have.
    ID's leading lights, Behe and Dembski, certainly have their fans - just not among anyone who understands information theory or evolutionary biology.

    The problem with the second part is more serious, in that it leads inevitably to a supernatural designer -- if nature is incapable of creating what we see using the laws of physics and observable processes, then there's no other way for such a designer to exist.

    Positing a supernatural designer is religious, therefore ID is religious.

    Saying that there was a _natural_ designer, as someone like Erich Von Daniken was prone to imply, would be a design idea that would be perfectly scientific (if evidence, predictions, etc, were forthcoming!).

    Your answer has nothing to do with my original statement.

    If you're going to dismiss everything I say as 'semantic quibbles', then what can I say in return? You don't seem prepared or able to engage with vital aspects of the issue of whether ID is science. I would think that the exact concept of theory is very important here, as ID has so many philosophical implications.

    quote:

    With pleasure. That was where the departing editor broke with the written rules for accepting papers for the publication by avoiding part of the editing process, was it not? It can hardly be called peer-reviewed if the rules were tweaked especially to get it past some of the filters. Unsurprisingly, the journal owners were not happy when they found this out, and that the resultant paper was of a much lower quality than they would have expected.

    I expect that's why Behe was unwilling to quote that (or any) paper in court as an example of peer review.

    quote:
    Behe said he had come up with his own “broader” definition of a theory, claiming that this more accurately describes the way theories are actually used by scientists. “The word is used a lot more loosely than the NAS defined it,” he says.

    Bizarre. Are you saying that ID can only function as science if we go back to the point where science and the supernatural were seen as equivalent? That's certainly in keeping with Behe's concepts of theory. However, there is a reason that science and the concept of theory has moved on from that point - some aspects of a Behean early modern mindset just don't hold up against empiricism.

    Demonology was once a perfectly respectable scientific theory, for example, based on the scientific treatment of people's reports of demonic activity. It was only when those reports themselves were investigated and no way of finding proof found that demonology failed - ironically enough, because it made unfalsifiable claims that could not be tested in court. The lawyers killed it.

    In the end, things like demonology, astrology and alchemy didn't survive the rigorous application of empiricism while astronomy, chemistry and physics did. ID belongs in the former mindset, and I'm pleased to see you implying that. I'm also glad to see that you feel the nature of theory is in fact important, rather than a mere 'semantic quibble' which is how I somehow misread your earlier statement.

    quote:
    Rothschild [prosecuting - RG] suggested that Behe’s definition was so loose that astrology would come under this definition as well. He also pointed out that Behe’s definition of theory was almost identical to the NAS’s definition of a hypothesis. Behe agreed with both assertions.

    Quite right. Thank goodness we're out of the woods of semantic quibble and dealing with important matters, eh? OK, one last quibble - that's "The phrase" I was looking for, not "The word". Tricky thing, logos. Perhaps Dembski has something to say about it.

    quote:

Could you point out where you covered the content of my ideas? Thanks.

    quote:

    Don’t misrepresent Behe, he said nothing of the kind. We are going to fall out very fast (again) if you cannot cite witnesses correctly. If I remember correctly, the cross-examination was about Behe’s understanding of the word “theory” and his answer was about how loosely the word is used in the scientific world.

    and might thus have actually read the transcript and care about citing witnesses correctly.

    I'm at a loss now. If you're prepared to claim the judge made errors of logic and fact but are not prepared to actually discuss the court transcripts then we are both wasting our time. Alternatively, if you are unable to remember whether you read the transcript or not, we're still on a hiding to nothing.

    We might as well stop here. Sorry for wasting your time.

    I think it will be up to other lawyers and judges to decide whether this judge was legally justified in going out of scope to the extent that he did. If you bother to read my posts, you will find that I have criticised him for his factual errors and for the illogical arguments in his consideration of ID theory. I have not attacked him on a personal level simply because I disagree with his conclusions.

    Based on my distinctly limited understanding of American law, this was not the case. The best part of the judgment is where the statements and actions of the Dover School Board are laid out and dissected. They clearly show a religious motivation for the policy change and that was enough for the court to find for the plaintiffs.

    It would have been no different if the policy change had been, say, a proposal to modify the English literature syllabus to study the King James Bible. If the intention had been to study it as a landmark of 17th century English Literature for secular education purposes only, that might have been acceptable to the court. But if the intention had been to study it as the sacred devotional writings of the Christian Church, that presumably would have been unacceptable.

    In this case, the fact that the (former) school board members were recognized clearly as pushing ID for religious reasons, and lying about it (nice Christian witness there), was what I think really pissed off the judge and rightly so.
    Yes, this part of the judgment was very well done and I agree with his conclusions. But please note that the judge only made allegations of lying against two named members of the board. He does not charge the remaining members of the board with lying.

    Have you actually read the judgment? The judge commended Behe for his bona fide endeavours whilst not accepting any of his conclusions.

    This is a discussion board. This issue is in the headlines. I take an interest in this subject. I like to post. I present a different point of view. Get used to it.

    I haven’t been horrible to the judge, although I did agree with one personal criticism made by the DI. I have done him the credit of reading his judgment in depth twice and now I am taking issue with some of his arguments. That is what some other judges will do in due course. Unlike some on this thread, I am discussing the issue, not the people.

    Demonology was once a perfectly respectable scientific theory, for example, based on the scientific treatment of people's reports of demonic activity. It was only when those reports themselves were investigated and no way of finding proof found that demonology failed - ironically enough, because it made unfalsifiable claims that could not be tested in court. The lawyers killed it.

    It was indeed killed off in practice by judges and lawyers who realised that there was just no way in practice of getting reliable proofs of the crime of witchcraft (and hence they gradually began to refuse to try alleged cases of witchcraft) but it took a long time for them to come to that conclusion and the deaths of thousands of innocent people first. One of the big problems with it was once you brought the supernatural into it, it drove a horse and cart through reason and justice. It was impossible to disprove accusations, you would get this sort of thing:

    witness - 'But my wife couldn't have been at the Sabbath in the next parish that night - she was in bed with me and up at dawn the next day to milk the cows.'

    lawyer - 'Ah the Devil took her there in spirit, leaving a double in your bed and whisked her through the air and back in time for milking - the learned Bodin and Del Rio in their works speak of such cases'

    People who think unfalsifiable supernatural claims are fine in science, certaily wouldn't want to meet them in a courtroom being admitted against them.

    Rex Monday, this is not the Panda’s Thumb.

    Your comment above is a disgusting misrepresentation of what actually happened to Richard Sternberg, the former editor of that journal. Do you understand the necessity of checking out your facts before posting? Do arguments and evidence mean anything to you? Are you capable of doing anything other than indulging in spiteful smears and character assassination?

    Here is Sternberg’s own detailed account of the reviewing procedures that were followed for that paper and what then transpired to him for publishing it. The account makes it very clear that the paper was fully reviewed in accordance with the journal’s normal procedures.

    Since you cannot possibly know what reviewing procedures Sternberg was supposed to follow at the journal, or whether he did or did not follow them, I submit that there is no basis whatsoever for your allegations. In other words, you are blowing smoke and flying kites, and that is putting it politely.

    You allege a “break of written rules”, an “avoiding of editorial standards” and an “especial tweaking of filters”, a clear attack on both his professional competence and his personal integrity. I am not a lawyer, but based on my knowledge of UK law, your offensively incorrect remarks are potentially libellous.

    I suggest you apologise for yet another factual misrepresentation on this thread and then withdraw your remarks before they get the Ship into hot water. There will be no further interaction between us until this is done.

    FS:

    I suggest you take up your concerns with the Council of the Biological Society of Washington. Their statement on the affair can be found here:

    http://www.biolsocwash.org/id_statement.html

    and which, as it is a public statement, I feel justified in posting in toto.

    "STATEMENT FROM THE COUNCIL OF THE BIOLOGICAL
    SOCIETY OF WASHINGTON

    The paper by Stephen C. Meyer, "The origin of biological information and the higher taxonomic categories," in vol. 117, no. 2, pp. 213-239 of the Proceedings of the Biological Society of Washington, was published at the discretion of the former editor, Richard v. Sternberg. Contrary to typical editorial practices, the paper was published without review by any associate editor; Sternberg handled the entire review process. The Council, which includes officers, elected councilors, and past presidents, and the associate editors would have deemed the paper inappropriate for the pages of the Proceedings because the subject matter represents such a significant departure from the nearly purely systematic content for which this journal has been known throughout its 122-year history. For the same reason, the journal will not publish a rebuttal to the thesis of the paper, the superiority of intelligent design (ID) over evolution as an explanation of the emergence of Cambrian body-plan diversity. The Council endorses a resolution on ID published by the American Association for the Advancement of Science (http://www.aaas.org/news/releases/2002/1106id2.shtml), which observes that there is no credible scientific evidence supporting ID as a testable hypothesis to explain the origin of organic diversity. Accordingly, the Meyer paper does not meet the scientific standards of the Proceedings.

    We have reviewed and revised editorial policies to ensure that the goals of the Society, as reflected in its journal, are clearly understood by all. Through a web presence (http://www.biolsocwash.org) and improvements in the journal, the Society hopes not only to continue but to increase its service to the world community of systematic biologists.

    As for libel, I'll leave that to the hosts and admin to determine.

    Compare this short BSW comment with Sternberg's detailed accounts in the link given above. According to Sternberg there was no formal procedural requirement for an internal review by an associate editor separate to Sternberg. However, the paper certainly did receive the three normal external reviews before publication as well as being discussed informally on several occasions with other colleagues in the BSW. Before the paper was published an internal review within the BSW concluded that all was well with the review process.

    As Sternberg puts it:

    quote:
    The Meyer paper underwent a standard peer review process by three qualified scientists, all of whom are evolutionary and molecular biologists teaching at well-known institutions. The reviewers provided substantial criticism and feedback to Dr. Meyer, who then made significant changes to the paper in response. Subsequently, after the controversy arose, Dr. Roy McDiarmid, President of the Council of the BSW, reviewed the peer-review file and concluded that all was in order. As Dr. McDiarmid informed me in an email message on August 25th, 2004, "Finally, I got the [peer] reviews and agree that they are in support of your decision [to publish the article]."
    I will leave the Ship to make up its mind who is telling the truth here. It is a quality in short supply in Rex Monday's post, that's for sure.

    Thanks for your comments on the Wedge Document. I also noted that the DI comment on the Wedge Document was published just one day before the Dover judgement was published - and to date the DI has not commented in detail on p 68-9 of the judgement. I wonder why. Perhaps they have something in preparation - though I could not find anything on the website.

    So I will be interested to see if the DI does indeed publish any specific criticism of the judge's handling of the Wedge Document in the context of the judgement . Your own arguments re p68-9 are a different matter. After making every possible allowance for them, you have not persuaded me that the judge's use of Wedge Document extracts/interpretations in the judgement is unfair to either ID or the DI, in the specific context of the judgment.

    On Sternberg, this letter from the Office of Special Council should give all of us some pause for thought. It was not highlighted in Faithful Sheepdog's earlier link - but it is a quite remarkable document in support of Sternberg's assertion that he had been wronged.

    I can think of no reason why the Office of Special Counsel should have any axe to grind on this case. And given the decision that they did not have jurisdiction to pursue the matter, there is also no obvious reason why the counsel should have provided so much information to Sternberg.

    Given the admirable ability of regular contributors to this thread to digest lots of info, I would be interested if others, like me, tend to side with Attorney James McVay in concluding that the evidence re Sternberg's treatment is disturbing.

    This has nothing to do with the merits of the Meyer article. It does however suggest a certain aggressiveness of approach to heterodox views by members of the Smithsonian Institution and its Natural Museum of Natural History.

    If the e-mails contained in the McVay letter had been found in the annals of the Discovery Institute over a "mirror-image" controversy, I wonder what the reaction would have been. "Research Associate victimised for anti-creationist paper" is my best guess.

    Well, I don't know the answers to any of those questions. I know that the counsel was supposedly a political appointee and that there is currently a great deal of bad feeling between the US administration and many scientists, so there's one possible reason he would be supportive of Sternberg against an establishment institution.

    I also know that organisations go to great lengths to get rid of individuals connected with them that cause them embarrassment and that academic politics can be the most vicious sort going.

    It is impossible to tell for sure from the various parties' published accounts exactly what happened, except there was a vexacious and heated dispute. People will have to make up their own minds.

    What isn't in dispute is that the paper was published. Having read both it and critiques of it I agree with the board that it was poor quality science and not in keeping with the journal.

    Barnabas,
    I found this interesting reading about the Office of Special Counsel's conduct in this case.

    quote:
    The OSC claims the Smithsonian Institution essentially retaliated against Sternberg for publishing a pro-intelligent design article in the Proceedings of the Biological Society of Washington. But here's the catch: The Office of Special Counsel confesses 1) that it has no jurisdiction here; 2) that it hasn't heard the Smithsonian's full side of the story; and 3) that it doesn't want to consider the scientific merits of the argument against Sternberg. Nevertheless, it has produced a lengthy one-sided brief in his favor, which has understandably drawn Sternberg great publicity.
    There also seem to be some very serious questions about the Office of Special Counsel, raised by the Congressional watchdog body, the Government Accountability Office which indicate that it's not as reliable a source as first appears.

    It doesn't look like this case has had a proper legal hearing at all and I'm not sure the OSC is a reliable source. If any of our US attorneys who are better informed are looking in - perhaps they could comment? I'd be interested to hear.

    cheers,

    Thanks very much, Rex and Louise. Nothing will take away the taste of those scabby and aggressive e-mails but the links put the OSC in context. It is odd that such a long letter should have come out despite the absence of jurisdiction - I thought I saw an indignant attorney, but maybe there were other reasons.

    This is an intense battleground of ideas and a straightforwardness about the truth of things seems to have already become a casualty of the war.

    Barnabas62, thank you for following up some of the links I provided and for making your own enquiries. This issue has some surprising twists and turns. It never ceases to amaze me what turns up.

    As for the posts above by Rex Monday and Louise, it doesn’t surprise me in the least that both want to examine the OSC rather than looking closely at the behaviour of the Smithsonian Institution that prompted the OSC to get involved in the first place. Neither of them has condemned the abusive treatment dished out to Sternberg and I find that contemptible.

    As a general background resource on the issue of adult bullying you may like to study this extensive website to get some further understanding of the abusive treatment dished out to Sternberg as understood by an authoritative secular source that, so far as I know, has no ID sympathies.

    quote:

    The OSC did their job well as far as I can see. As a sort of American Ombudsman (the UK term) they are supposed to represent the interests of someone in a position like Sternberg’s. Unfortunately Sternberg was on some kind of freelance contract that gave him less legal rights than a full employee. Hence the OSC had limited jurisdictional scope to force cooperation from the Smithsonian Institution.

    It would appear that after some initial cooperation, the Smithsonian Institution declined all further cooperation, perhaps because the information coming to light was so damaging to them. Why decline cooperation otherwise with an official government body?

    I certainly agree with you that this evidence is “disturbing”. Sternberg’s treatment was just a small sample of the nastiness dished out in certain circles to anyone with the least hint of an ID sympathy. This is not science; it is a powerful ideological orthodoxy punishing the heterodox. Sadly you will find more of this if you go looking.

    As for my ability to keep up with this subject, the positive side of being stuck at home with ME/CFS is that in my better patches I have had a lot of time to read and study on issues that are of interest to me.

    A bit of Googling found out the following.

    1. Meyer's paper is available online and here it is.

    2. Here is an initial criticism.

    Many contributors to this long thread may have seen both of these (and other related links) and I apologise if I've missed earlier links and this is "old hat". As it was easy to do, I thought there might be some value for newer contributors and lurkers to see what lay behind Sternberg's difficulties.

    I found Meyer's review essay relatively easy to read and interesting. The initial criticism seems to me to land some pretty effective blows on the credibility of the review essay - and I can see reasons for Rex Monday's scepticism over the quality of the essay. I just think it is a pity when people "play the man instead of the ball". It never impresses me. None of this looks like a sackable offence in any case, nor sufficent grounds for a witch-hunt of the unfortunate and possibly unwise Sternberg.

    Anyway, I'm off to find out more about the Cambrian, armed with loads of references! That looks like a fun project for a retired old codger like me.

    For those who are still interested in discussing the trial and its aftermath, especially the fury with which the religious right has turned on Judge Jones, I can recommend a piece quoted approvingly by the Disco Institute and written by Phyllis Schalfly.

    It may be most of interest to those who consider that the judiciary should be independent, those who've actually read his judgement or those who consider that the constitutional issues raised include whether ID is science or religion. Schalfly is incandescent with rage - alas, she doesn't quite manage to give any quotes to back up her many accusations, and despite my familiarity with the judgement I've been unable to match what she says with what JJ wrote.

    It's a shame that those who disagree with the judgement aren't able to progress beyond this sort of diatribe. But hey, go read. It's highly recommended.

    That overstates and misrepresents the situation. Furthermore, you have cited no evidence to define the precise brief of the OSC under the American legal system.

    The nature of Sternberg’s contract at the Smithsonian may only have become clear to the OSC at a later stage in the investigation and that may simply have meant that the OSC could not force the Smithsonian to cooperate further. That does not mean that the Smithsonian could not cooperate voluntarily, as it clearly did do in the early stages of the investigation.

    Again, don’t put words into my mouth. Stop misrepresenting me.

    I haven’t said that either. This is getting very tiresome.

    I consider that the evidence provided by Sternberg’s detailed account and the further evidence found by the OSC’s investigation to be of a very high quality and to present a very substantial case. I hope that Sternberg has a good lawyer working for him now that the OSC has bowed out. I would like to see this evidence tested in court.

    The only contrary evidence is the statement from the BSW that is clearly flawed and deeply inadequate. Since when, in any organisation, has the full editor of a journal been required to defer to an assistant editor? There may be circumstances when that is desirable, or even advisable, but it cannot be said to be compulsory without demoting the editor and removing his editorial authority.

    Other then this bald assertion that flies in the face of common sense, the BSW have produced no other evidence about their required internal operating procedures and the alleged lack of compliance. To my mind they are clearly engaging in irresponsible blame-shifting and character assassination that has had a very deleterious effect on Sternberg’s reputation and career. At worst it is a cynical exercise in corporate lying.

    quote:
    despite evidence from another government body which investigated them that they're not doing their job in a proper and impartial manner at the moment.
    You overstate your case markedly. In this particular affair there is no evidence that the OSC acted improperly or incompetently. If you want to discuss the OSC in more general terms, then start a new thread. Stop trying to divert this one.

    I agree with you and Callan. In its own emetic way, the article is a classic. I searched the DI website and found only one reference to Ms Schlafly (in a list of names) so I'm not sure about DI endorsement. They would be pretty foolish to do so - particularly given the excerpt Callan quoted.

    Formally, the judgement stands as a matter of law until it is knocked down. If it is uncontestable legally, then there is scope for political action. Rubbishing the judge does absolutely nothing for the credibility of those who find the judgement to be faulty. The "best" they are doing is reassuring themselves.

    A final comment on Sternberg. It seems pretty clear from the e-mails that he was targetted. It seems pretty clear from the review essay as published that he painted the target on himself. If the Meyer review essay had had an effective peer review, then the critics on Pandas Thumb (my earlier link) would not have been able to score such easy hits. And that, of course, is one of the real values of critical peer review. It leads to an improvement in what is published. Unless of course your intention is only to get something - anything - published, just to make a point.

    I think there are two issues being muddled here.

    First is a proceedural and an editorial dispute. This seems to revolve around whether a previous editor of the journal should have edited the paper alone (as it says he did with many other papers). I doesn't seem that there is any argument that the paper was actually peer reviewed (although there are questions about who the reviewers were).

    Second is a dispute regarding the science and the writing of the paper.

    I am not qualified to comment on either issue. However, it does seem to me that there is an inbuilt inertia built within the frame of reference of any journal - and papers are only normally published that fit within that framework. It would be extremely difficult to publish something with the best science and written in the best way that went against the prevailling view.

    Publishing papers that others disagree with is hardly new nor a reason in itself to doubt the veracity of the writer. Any literature research over any time will produce papers that will flatly disagree with each other yet have been published.

    Generally I'd agree with the statement at the end of the Panda's Thumb website

    quote:
    There is nothing wrong with challenging conventional wisdom — continuing challenge is a core feature of science. But challengers should at least be aware of, read, cite, and specifically rebut the actual data that supports conventional wisdom, not merely construct a rhetorical edifice out of omission of relevant facts, selective quoting, bad analogies, knocking down strawmen, and tendentious interpretations.
    Although I'd suggest that Mayer has produced an incomplete paper rather than being deliberately malicious (of course that is a matter of opinion -but then that is part of the point of a review paper isn't it?).

    I think we all need to get over ourselve here a bit. If the ID crowd can produce interesting papers with reasonable evidence and argument then let them. To flatly dismiss them because you don't happen to like the conclusions smacks of nescience rather than science.

    I do agree so much with your "getting over ourselves" point. The problem I think is that the two separate issues interrelate because;

    a) publication space by reputable organisations is a scarce resource, requiring proper discipline and control over its filling, and

    b) a perceived failure of quality control damages the reputation of the publication (for accuracy, impartiality, truthfulness etc) and its sponsoring organisations.

    Frankly, I would be amazed if both Sternberg and Meyer did not see now that there had been some failure of quality control in the peer review process prior to publication. Regardless of whether it was procedurally appropriate, the peer review as carried out did not do a good job. Meyer's essay is an interesting read, but should not have been published without some attention to the holes in it which were so easily found afterwards. When handling a hot topic, great care is required.

    We will have to disagree that the Panda's Thumb have scored "easy hits". I will limit myself to one comment on their extensive review. Their comments on genetic algorithms are completely wrong. Whether a target sequence is explicitly specified or is implicitly given in some another form, it is nevertheless always there in these algorithms. That is why they work so well, and why they are evidence not for Darwinism, but for ID.

    Also, please note how you have shifted the ground of the argument about the review process of the Meyer paper, both here and in your later post. The argument now is not that the paper received no review at all, or that it did not receive a review to the proper BSW procedures, but that it did not receive an effective review.

    I would like to know what you mean by an "effective review" in relation to its oposite, an ineffective review.

    I cannot see that publishing an academic paper that contains a controversial viewpont or is vulnerable to counter arguments does not mean that the review process was thereby automatically ineffective, or that the paper should not have been published. On those criteria most academic publishing would come to a grinding halt.

    Yes, I do have evidence. Read Chapter of 4 Dembski's Book No Free Lunch, which is cited by Meyer in his paper. It contains an extensive mathematical discussion of genetic algorithms and supports my viewpoint.

    And yes, I do have sufficient mathematical knowledge to understand what I am talking about. I actually reached my viewpoint on these algorithms before reading that chapter in Dembski's book, so I also refer you to the numerous posts I have made on this thread in Summer 2004 in respect of an electronics experiment using a genetic algorithm and in Summer 2005 regarding the AVIDA software.

    It is common academic practice for one author to cite another. Of course that means Meyer's argument depends on the correctness of Dembski's argument. Dembski's argument in turn is based on the mathematics of probability and information theory applied to genetics and biology. That sounds like evidence to me.

    Excuse me, I'm quite aware of this. I have no access to the resources and neither of us really know what we are talking about (possibly me even less than you) it is a pointless discussion, wouldn't you say. It'd be like me taking a book off a shelf in my room and saying 'here, it says so on page x.' That isn't evidence FS. Unless you have studied mathematical genetics in an academic institution at a high level, it is second or third hand information is it not.

    Has Dembski ever published his argument in a peer reviewed publication? (I'm assuming that his book wasn't peer reviewed, as that would be highly unusual). I freely admit that my maths isn't upto determining the correctness, or otherwise, of Dembski's argument. That's the point of peer review - to put a paper through a first stage of comment by people who are qualified to comment before publishing it so people who aren't knowledgable enough to spot errors but might still be interested in the paper can read it. Of course, peer review doesn't actually stop with publication - there's always the option of others to offer rebuttals, corrections to be published etc.

    I'm still waiting to see details of how I misrepresented people by reading their own words in the trial transcript, but while we're waiting...

    quote:

    This is a fundamental misunderstanding of genetic algorithms in particular and the basic principles of modelling in general.

    What those sequences represent is fitness. They are analogous to evolutionary features in living organisms that render those organisms better able to survive in a particular environment.

    In an animal, that may be the ability to metabolise a particular compound or to run slightly faster; in Avida, it's the ability to perform an arbitrary function which has been predetermined. This is an analogy of natural selection in real life.

    Perhaps it might be easier to understand if you look at it another way. Assuming you are right, and the presence of a pattern to be evolved towards is an indication of intelligence, how would you program a model so that this was avoided? What model of evolution excludes a test for fitness - or how would you have a test for fitness that doesn't involve an algorithmic comparison?

    In short: if Avida gets it wrong, how would you create a computerised analogy that _accurately_ tests the principles of Darwinian evolution?

    As I've said before, that would be an excellent way for IDers to actually demonstrate that there is a problem.

    Of course, that doesn't mean that I don't have things to learn or that I am automatically right. This is a huge subject and my reading list is growing faster than I can deal with at present. However, I am happy for Cheesy not to listen to me if he so chooses.

    Actually, this is a reference to Dembski's previous opus magnum The Design Inference. This was published by Cambridge University Press in an academic monograph series and was definitely subject to a rigorous peer-review process that lasted about a year (I think). I have posted Dembski's description of that process earlier on this thread.

    His later mathematically-oriented book No Free Lunch was not published by CUP but by the American publishers Rowman and Littlefield. Dembski explains the reasoning for this change somewhere on his own website. I will have to do some digging to find out what peer-review process (if any) that later book went through.

    Dembski engages extensively with the comments of his critics here.

    I have to say peer review often seems pretty over rated. Two or three random experts get chosen - who may pass the manuscript onto a less busy junior colleague.... sometimes they miss things that should be picked up on, sometimes they seem to be having bilious days... you get some comments back, the editor looks at them, and your answers - perhaps he/she will ask for revision, perhaps feed back to the referees, perhaps not.

    When it works well it's fantastic, but in many biological journals it's a bit hit and miss.

    While we're on that subject, this proceedings of whichever Washington society that Meyer's paper appeared in is not a terribly high-profile runner. It's not a big deal if they publish something dodgy every so often. I've seen worse papers accepted in higher profile places. I'd leave the poor editor alone to eek what's left of his career in peace, myself.

    I note Meyer's not published anything else peer reviewed in a searchable place... certainly doesn't seem to have ever come up with any data.

    Unfortunately the list of 72 articles doesn't allow them to be sorted by type. But going through the first few one at a time there are several newspaper articles, an essay in a book (which he edited), that article, an article in the proceedings of a design conference (no information about if the proceedings were peer-reviewed), and a letter Nature wouldn't publish. Not much that would turn up in a BIDS search.

    If this website is accurate the Dr Mayer has the artiles in the following Journals (in addition to the famous one)

    Trends in Ecology and Evolution March 2004 (letter)

    First Things: Journal of Religion, Culture and Public life April 2000

    Utah Law Review Feb 2000

    Journal of Interdisciplinary Studies Jan 1999

    Journal of Rhetoric and Public Affairs (I kid you not) October 1998

    Intercollegate Review 1996

    Perspectives in Science and Christian Faith: Journal of the American Scientific Affiliation 1994 and 1986

    The rest are newspapers, books and self-published articles.

    So that'll be nothing at all then.

    The norm on university websites when giving lists of publications is to just give the reference details, and sometimes the abstract. I don't see any reason why the Discovery Institute couldn't do likewise for those articles that it can't reproduce in full. Then anyone who has access to the relevant journals (eg: university staff and students) can get them if interested.

    That is no excuse.
    Look at this random academic's homepage

    He is on top of his game and has published papers coming out of his ears. He doesn't put the paper online but he does list where they are published.

    Dr Mayer doesn't, in contrast, because he has published only 10 papers of any note in the whole of his career.

    When you get it don't forget to add in all his professional work as a geophysicist with the Atlantic Richfield oil company.

    The range of papers Dr Meyer has published (I'm no academic, so I won't enter the argument as to whether size matters in his particular case) illustrates for me a fundamental point about this whole controversy - ID is being discussed as if it were science when it is in fact philosophy. Discuss it all you want in Philosophy class, or in RE (or whatever it's called these days) or Social Studies, alongside other Christian responses to science (e.g. Polkinghorne, or the Vatican's relationship to science over the centuries). Give it half an hour in biology to demonstrate the presence of alternative theories, making it clear how it's as much an interdisciplinary philosophical approach than pure science (because I think people would benefit from knowing that there's a whole lot of that going on in science too - you could include it in a module that covers people like Popper and Polanyi, too).

Give it half an hour in biology to demonstrate the presence of alternative theories, making it clear how it's as much an interdisciplinary philosophical approach than pure science (because I think people would benefit from knowing that there's a whole lot of that going on in science too - you could include it in a module that covers people like Popper and Polanyi, too).

    I don't think it belongs in biology, because it's only one of very many non-scientific takes on a scientific subject.

    I think there should be more time spent in school, even at secondary level, teaching how to think - practical philosophy, I guess, comes close.

    That could easily include the philosophy of science, techniques of criticism, a look at what theology actually is, and so on. It would be the natural place to put ID, alongside the huge number of other non-empirical theories of existence.

    I would like to know what you mean by an "effective review" in relation to its oposite, an ineffective review.

    I cannot see that publishing an academic paper that contains a controversial viewpont or is vulnerable to counter arguments does not mean that the review process was thereby automatically ineffective, or that the paper should not have been published. On those criteria most academic publishing would come to a grinding halt.

    Neil

    You are confusing me with Rex Monday I think. I never said that the Meyer essay had not been peer reviewed. I think it had been. I am questioning how well it was done, that is all.

    What is an effective review? Well, just as an example, the section in Meyer's paper entitled "Novel Genes and Proteins" looks particular vulnerable to the criticism that it ignores a large number of papers on the subject of the evolution of novel genes. See the section in the Pandas Thumb criticism, headed "The origin of novel genes/proteins". Meyer's scepticism is expressed this way

    quote:
    Many scientists and mathematicians have questioned the ability of mutation and selection to generate information in the form of novel genes and proteins. Such skepticism often derives from consideration of the extreme improbability (and specificity) of functional genes and proteins.

    And he does indeed develop that argument. But if there is research work pointing in the other direction, it would be have been prudent to acknowledge the existence of this work. Meyer does not need to abandon his understanding just because of this work, but he weakens his own case by not acknowledging it. It makes him look ignorant, or dismissive. I suggest that an effective peer review might have identified this possibility and resulted in a modification of the paper. That way, a legitimate criticism of the paper as published, and that about a central point of his argument, could have been mitigated or avoided.

    I could give other examples along similar lines. I am not claiming the advantage of 20/20 hindsight either. As I said in another post, the "hot issue" factor should encourage a cautious approach, recognising the controversial elements of the paper.

    I've read about a third of this thread - good reading.

    Incidentally, in case it has not appeared in this thread - a few other links regarding ID
    http://www.uncommondescent.com
    (this is the daily web log of Dr. William Dembski)

    Also,
    http://www.arn.org/ubbthreads/ubbthreads.php

    This (above) is an ongoing discussion on ID and goes beyond many of the usual basics or initial discussions of ID.

    I personally believe that ID has merit, but needs development. The matter of Dr. Richard Sternberg http://www.rsternberg.net/ speaks of his ordeal a little more.

    I read also that he actually didn't agree with ID, but introduced it because he felt that science grows from controversy.

    I believe the dilemma of ID probably won't be concluded for years - I've discussed it at length at other boards as well.

    If ID does advance, it will not be from sermons, but from science.

    Another dilemma facing ID is the reflexive reaction against creationism (by a wide variety of groups/people/etc).

    A debate is not necessarily the best place to have enlightenment - too often the topic doesn't get plumbed much past it's surface.

    If (and I mean "if") ID is to advance, it must be from the workhorse of science. Not debates, courtrooms or the pulpit but true science. To the joy of ID critics, this will likely (IMO) take much longer than the ID proponants would wish.

    While I personally believe this world was created - to find empirical proofs to instantiate ID and quantify it enough to show evidences to quench the critics will take the time that science usually requires (many years).

    While from my own research over months leads me to believe there's merit to ID, I also believe it has a distance to go - many years and patience for it's science to be able to speak for itself.

    Indeed. Which is why the curious lack of ID proponents actually proposing or executing scientific experiments is doing nobody any favours.

    quote:

    I don't think it's creationism per se, it's creationism that claims to be scientific that gets people going -- and that mostly because of past experience. A genuinely new idea, even if it's completely against orthodoxy, will always get a hearing. ID is at the moment almost entirely a collection of criticisms against evolution, very few of which are new.

    It would help if they got started! I've never, ever seen a proposal for an ID experiment, let alone a full course of research. There are no predictions made, no theoretical framework being hypothesised. They've got support, they're well funded... what's stopping them?

    That's the frustrating thing. There's nothing to stop ID from proving itself: you can't ban people from doing science, nor would anyone want that. If ID is correct, then we should take it seriously - and I'd rather know that sooner than later, there's no pleasure in seeing the truth delayed.

    But a science without a single repeatable experiment or testable prediction to its name cannot make that claim - and there seems so little pressure within ID to change that. ID proponents' conviction that ID is correct seems curious in that context.

    And it is even more curious that anyone would push for addition to the basic evolutionary biology science curriculum anything that has not one repeatable experiment or testable prediction.

    These things move slowly and should. I have an Earth Science textbook from the year boo that reflects the not-yet-acceptance of the exciting new theory of plate tectonics, now widely accepted, peer-reviewed, tested. Anyone familiar with the field knows how long it took that shift to occur and that was for something testable and tested. But other than personal reputation, there was very little ideological investment in either outcome. Where, as here, the proposed alleged "science" is untested and largely untestable, and there is a powerful non-scientifically based ideological force behind it, great piles of salt and caution are due before letting it anywhere near a school, unless it's into the philosophy department.

    Personally, my main concern with anything that is essentially creationism in disguise is the theodicy problem. But that's been covered, I'm sure, extensively on this thread.

    I would recommend that you check out the factual basis for your comment. You will find that it is another misrepresentation.

    From the highly recommended blog Telic Thoughts there is a very good example of a clear prediction from ID theory that is both testable and repeatable. See here. This is a rather technical post about a specific part of the genes of modern organisms called "tool-kit genes".

    The most relevant paragraph, with my bolding, is:

    quote:
    If we assume that eukaryotes were designed with the purpose of giving rise to multicellular organisms, we can make certain predictions. For one, we would expect the first eukaryotes to have contained a predecessor to the modern tool kit, and it’s possible that some unicellular eukaryotes still possess it. It will probably not be the full set possessed by modern organisms (or rather, full sets, as several organisms differ in the number of genes they have), as some genes may have been generated through gene duplications, but I definitely expect genes that are clear precursors to modern tool kit genes to be found in unicellular eukaryotes.
    To me that looks like a clear prediction that is both testable and repeatable. It is open to refutation by subsequent knowledge.

    You will find more testable predictions from ID theory if you go looking.

    I suspect the answer is "not yet". As to why, I suspect the problem is a lack of money.

    Academic research lives or dies by its funding. A hotly controversial idea that is presently a minority opinion may not be in a position to obtain many research funds. That, incidentally, is one reason why the Discovery Institute exists, to fund research in ID and other areas that are of interest to it.

    Yes, yes, but I don't see how - even if one was to prove it - one couldn't use the explanation within conventional accepted evolutionary theory.

    Nope. It still would not and could not establish that intelligent design must be behind such a change. Nothing could or would. It might be interesting for other reasons, but it would not establish the principle for which you propose it.

    To an extent. Funding is only normally forthcoming to research that has potential and falls within the normal bounds of science.

    Seems to me highly likely that yon Discovery Institute is nothing more than a propaganda tool, producing nothing approaching original science by people with very little credibility.

    If it isn't let us see the original science. ISTM that we can't because there isn't any. Yes, there are some interesting books and ideas - but nothing that would stack up in a court of law or a scientific journal. I'm afraid that even this paper we've been discussing hardly counts as a scientific paper FS - apart from anything else it is a review paper and includes no original science.

    Exactly. One would expect precursors - albeit with a different function - in unicellular prokaryotes. No-one is suggesting that a mutation occured in a Paramecium one day and the next it became a sponge. New functions arise constantly in evolutionary history from pre-existing structures with a different function.

    Laura, you can't have the argument both ways. Eiher ID theory can generate testable and refutable predictions, or it can't. I have given you one such example and shown that it can do so.

    No one is claiming that if the specific prediction concerning tool-kit genes proves to be correct, it thereby establishes ID theoretical ideas in toto. Science simply does not work that way.

    By the same token, if the specific prediction proves to be false, that would not comprehensively falsify all ID ideas.

    True, but if you find promising results, you have to be able to prove why they correspond to your explanation rather than everyone elses.

    Creationists regularly come up with alternative explanations for scientific results. Why is ID any more plausible?

    Whilst interesting, these results wouldn't make the blindest difference in the ID discussion one way or the other.

    The key question is from what theoretical basis the successful prediction was made. If theory A enables researchers to make predictions that on testing are found to be correct, and if theory B is making predictions found not to be correct, then we have a clear clue as to which theory may ultimately prove to be true.

    If researcher A are making discoveries (pretty big if there given that there is no evidence of any original science) which can be easily assimilated into the existing theory Z rather than the newly postulated theory Y then the even if the science by researcher A is good, it is no help in deciding between Z and Y, and moreover if researcher A is a propaganist for theory Y then people are not going to believe his evidence, right or wrong.

    So your prediction is that historical tool-kit genes would have functioned in the evolutionary predecessor not as rudimentary tool-kit genes, but as something else entirely instead?

    In that case how does one establish that the historical genes in questions are rudimentary tool-kit genes, and not the rudiments of some other genes?

    They will contain some identical or near identical sequences to the current genes.

    Same general idea as how we know that the genes governing the blood clotting cascade derived from a single several times duplicated gene - the current genes, although having different functions albeit within the cascade, have unnecessarily identical sequences within them.

    This thread will find yet another peer-reviewed paper that makes uses of the ID work of Behe and Dembski here. It is by a German biologist working under European and Indian(?) editors. It is further evidence that a court in Pennsylvania decides the law in Pennsylvania and nothing else.

    I haven't read this paper properly yet, but at the end the author posts the following delightful paragraph:

    quote:
    It should be stated that the hypotheses of Behe and Dembski and my applications of them to the further biological phenomena as decribed above have been formulated in an intellectual climate of enormous tensions between different world views, often so much so that it seems to be necessary to point out that an author supporting ID is speaking not in the name of an institution, but gives his personal opinion. However, I am fully convinced that there is a range of cogent scientific arguments (of which some have been discussed above) encouraging open-minded researchers to carefully consider and investigate the topic within their different biological disciplines.
    He is certainly right about the "enormous tensions". [Smile]

    That's an interesting essay, although it does seem to be an advanced argument from incredulity. It ignores the small problem that none of the 'irreducibly complex' systems have been shown to be anything of the sort, and that Dembski's probability calculations don't seem to have any applicability in the real world.

    "On the other hand, as to the candidates of irreducibly complex systems mentioned above (the cilium, bacterial flagellum, blood clotting, traps of Utricularia and some other carnivorous plant genera, joints, echo location, deceptive flowers as displayed by Coryanthes and Catasetum etc.), it can be confidently stated that up to now, none of these synorganized systems has been satisfactorily explained by the modern synthesis or any other evolutionary theory."

    That's the problem - it cannot be confidently so stated. Take blood clotting, the evolutionary origins of which are discussed at Evowiki . That looks as reasonable an evolutionary explanation as any other, and Behe's objections have been repeatedly met - like here.

    I've tried to dig further into the author, but most of his work's in German and Google's translator is of only limited use here. However, he does have the occasional burst of English...

    "Of systems that in principle are comparable we know how they come into existence and how not: they never come into existence by "chance" (definition pp. 15/16), but exclusively through consciousness, purposefully working intelligence and genius. Using experience as yardstick shows clearly that consciousness, intelligence and genius are absolutely necessary as the cause for the origin of the information for the design of the immensely complicated organic structures, which are so marvellously attuned to the highest precision."

    So he's no stranger to argument from incredulity!

    As for his proposals for research and predictions: I'm delighted to see them - although they do implicity agree that there's a lot more uncertainty about the theoretical underpinnings than his bold statements before would admit. Show that systems are really irreducibly complex? Well, yes! How? He does not say, and the rest of the proposals are pretty much predicated on getting that bit going. So that's not terribly helpful.

    But it's a start.

    I'm pushed for time today, so I will have to return to your post in due course. For "target sequence" I should have used the broader and more correct phrase "target function". The word sequence in this context is ambiguous and misleading. With that correction I still stand by my comment about the review at the Panda's Thumb and I disagree completely with your viewpoint.

    Since you have mentioned your credentials I will also mention mine. I have two mathematically-oriented engineering degrees plus some programming experience in fortran. I used to work on nuclear safety issues.

    [Apologies to all for digging up the extinct equine]

    Tonight, Horizon on BBC will be looking at Intelligent Design and related stuff. Including the results of a MORI poll that according to the BBC News report shows what (to me) seems a very large belief in Intelligent Design/Creationism in the UK with less than 50% of respondents believing that evolution best describes their view of the origin and development of life.

    Seems very unlikely. How many British people know the first thing about ID?

    Who are these participants and how are they selected?

    I wish I knew. The BBC News page doesn't give any information, nor does the Horizon page. And, there's nothing at the MORI site either.

    I'd find difficulty believing those figures if the poll had been conducted at Spring Harvest, let alone on the high street.

    Not only who these people were, but also exactly what questions were asked would be good.

    You can believe in Intelligent Design without claiming it is science. I'd guess lots of people would say they believe in ID who also believe that's a theological statement, not a scientific one, and who would oppose any drift of ID into any science class. I'd also guess lots of people who believe in evolution also believe that God gave the process a push at the outset -- and that will be what they mean by ID.

    Which is true enough. But, I'd be surprised if the majority of the British population was that aware of the difference between ID and YEC. Mostly, if they've heard of it at all, it'll be from media reports about school boards etc in the US which (over here at least) tend towards "what those Fundamentalist Evangelical Christians are trying to do". It certainly doesn't explain the 41% of respondents who want ID taught in science lessons.

    That's what simply does not make sense about the poll results. When you get, maybe, 10-15% of the population regularly attending church, how do you get 40% or so of a poll saying that Creationism should be taught in science lessons???? Unless the 2000 people questioned were not even remotely representative of the UK population.

    My Science&Religion prof always made a careful distinction between belief in intelligent design (that the positive aspects of the world supported a creator) and Intelligent Design Theory (that said belief is scientific).

    So I would believe the first but not the second.

    But you're right, given the question, the numbers seem wrong. Maybe the same pollster that found [mumble high] percentage of people thought DNA was added to GA food?

    Presumably anyone at all who believed in God would claim at least that, and be in that sense a "creationist".

    And many (most?) of us would go further and believe that God is sovereign and continually upholds and directs and in a real sense "designs" the world, living veratures and everythign else. What they used to call "Providence".

    What is less likely to wash is the specific claim that's being marketed as "Intelligent Design" in the USA. Which, as Alan says, I doubt many people over here (or over there) really distinguish from old-fashioned theisim + evolution.

    I was just discussing this with a (non-religious) friend, who is as disbelieving of the poll results as I am - and I'm not looking forward to having to watch Horizon to find out exactly what the poll asked and of whom (not that they're likely to say). Horizon has gone downhill badly since the days it assumed the viewers could hold an idea in their head for the duration of the programme.

    In any case, any poll that doesn't include the question "Can you describe the principle features of biological evolution, as understood by mainstream science?" isn't going to show anything more than most people's vaguest feelings. It's like asking the average English person "Do you believe in God?" which is likely to evince a "Yeah, guess so" - it's only when you ask "Could you describe that belief?" that you find it's no more than a hunch.

    Here in the US, at least in my definitely small sample of non-scientist, church attending Christians, the standard definition of intelligent design is "The world looks likes somebody made the world therefore there is a God." In other words, they define intelligent design as the argument from design by Paley et al and they see no differences betwen the two (and probably have never even heard of Paley).

    If that's true in the UK too then I can imagine that any question posed to the general public about intelligent design won't get a reliable answer.

    The programme itself was fine. It tried to be fair to the IDers, but couldn't quite resist the occasional dig and a touch of 'Americans are spooky'. And since it hinged on the Dover case, it really only had one place to go.

    Aha - I've found some more details of the survey at the BBC Press Office. And I think I see the problem - it misrepresents evolution. Here are the questions it asked:

    quote:
    The statements were:

    the 'evolution theory' says that human kind has developed over millions of years from less advanced forms of life. God had no part in this process;

    the 'creationism theory' says that God created human kind pretty much in his/her present form at one time within the last 10,000 years;

    and the 'intelligent design' theory says that certain features of living things are best explained by the intervention of a supernatural being, eg God.

    Of those surveyed, 48 per cent said evolution theory most closely describes their view; 22% chose creationism; and 17% chose intelligent design.

    I don't know many Christians who believe in evolution who would be happy with "God had no part in this process" - rather, the prevailing belief is that the results of evolution are in keeping with God's plans for the world.

    Evolution has nothing to say about God's involvement, other than there seems to be no evidence at a phenomenal level. Supernatural involvement? That's a matter of faith - it doesn't exclude mainstream evolutionary thought. But that question implies that it does, and that's wrong, and I cannot see how a thoughtful Christian couldn't have problems making that choice.

    So therefore, I think, the survey was doomed to underreport evolutionary acceptance.

    R
     
    Posted by Karl: Liberal Backslider (# 76) on :
     
    Indeed. I'd have to say "none of the above".

    The fundamental mistake made both by the survey question setters, the creationists and the likes of Dawkins is to assume that if something is done by God, it is miraculous. That physical phenomena, explainable and describable by science, may actually be the physical outworkings of the creative activity of God, is a concept that seems beyond them.

    Oh dear ... I'm stepping in on a Dead Horse and it's this one. What have you people done to me? [Biased]

    If I had seen that survey several months ago, I probably would have selected option three, but now that I have a clearer understanding of what ID is (thanks, in part, to the program last night), I would also have been unable select one of the options.

    Someone once told me that truth is like a two-sided coin. I'll try to explain. One side is the side that man can see and understand and analyse and is responsible for and the other side is the side that God is responsible for. The two sides can appear to be in conflict, but when you realise that there are different roles and different parts to the coin, you recognize that it still is the same coin, and they are still speaking of the same truth. In the current discussion you could look at the two sides as being science and religion. The science or man-ward side gives us the ability to investigate and try to understand the natural processes that brought us to where we are today. The religious or God-ward side reflects the nature of God in the process, and as Karl mentioned, His providence. The one side doesn't explain the other, but you need to look at both to have a fuller understanding of the truth ... a fuller understanding of the "organised chance."

    Oh, and the Jesuit priest/astrophysicist was absolutely stellar!
     
    Posted by Alan Cresswell (# 31) on :
     
    Thanks for digging out the questions Rex.

    My feeling is that the majority of the UK population (who, according to census info identify themselves as Christian, Muslim, Jewish etc) look at the physical world around them, the beauty of nature etc, and have at least a gut feeling that "God did this". When faced with the options given them by the pollsters they read the "God had no part in this process" and say to themselves "that's not right"; as most people probably don't opt for a "none of the above" they chose whichever of the other options seemed closest to what they believe. I suspect those who feel that humans are somehow different, more important or special would be more attracted to the "creationist" position. The very poor definition of the "creationist" and "intelligent design" options gave a lot more room for people to see how their view that God was, somehow, involved could fit them.

    The "should these be taught in science lessons?" part of the survey is more disturbing. That barely 70% thought evolution should be taught in science lessons seems truly bizarre. That at least 40% thought that either "creationism" or "intelligent design" should be taught is worrying, depending on whether they simply think that they should be mentioned as alternatives or taught as equally valid positions.

    Basically, if you really want to know what Brits (or, anyone else for that matter) think about such issues ask better questions that actually allow people to respond with what they believe.

    Has to be "none of the above" for me as well. What a tacky set of questions.

    Both "Darwinism" and "Intelligent Design" are "evolution theories" anyway.

    Since when do you do set curriculum based on what the average person thinks is a good idea? Especially using a survey. You find all sorts of crazy stuff in surveys because the average person is ignorant of most things, and they don't put much thought into surveys. This is the whole reason why direct democracy is a terrible idea.

    I'm not saying that we should base the science curriculum on the results of a popular poll, even if that had been conducted properly with a large sample of respondents and sensible questions.

    What I find bizarre is the outcome of that poll. In that I know of no one who wouldn't consider that evolution should be taught in science lessons. Even those who consider evolution to be seriously flawed wouldn't, in my experience, advocate not teaching it at all. I'd really like to know what the 30% who think evolution has no place being taught in science classes would teach instead when biology starts to point out things like "oh, aren't there a lot of different species of animal out there"?

    What does diversity of species have to do with evolution? Commonality among species is what ties evolution together. If all species where really diverse then Darwin would have never made the connection he did. We would have had to wait until we figured out micro-biology to see that animals were similar on basic levels.

    So to answer your question, they would say "God did it".

    Actually, Darwin made the connection because of the similarity of diverse species. When faced with evidence of a large number of different species of finch (ie: diversity in finch species) then a biology teacher must surely explain that in terms of evolution - exactly as Darwin did.

    Now I'm sure there are some people in the UK who would happily have biology teachers telling kids "God did it, just as it's recorded here in Genesis". But 30% of the population? No way! Which is what I don't understand about the poll, the numbers clearly indicate that the respondents were allowed to be inclusive (eg: "we should teach ID and Evolution"), and yet 30% didn't want evolution taught at all. Clearly there was something deeply flawed about the poll - and not just in the inaccurate descriptions of the options.

    Or God just made a number of different versions. If you allow God as science then you can "explain" anything by claiming God did it.

    That was what I was pointing out earlier. There are all kinds of sneaky tricks that pollsters pull to get news worthy results (my guess would be polling lots of fundamentalist churches). You also have to remember that in the general publics mind evolution (and science) is the antithesis of religion. People who actually had a proper education know that this is not true.

    Well, the press release clearly said it was a cross section of the UK population. Besides, even in fundamentalist churches (in the UK) there'd be a decent sized majority who would consider that evolution should be taught in science lessons - just that the "alternatives" be taught as well. As I said earlier, before seeing the questions asked, that response would be surprising for a broadly evangelical response such as that which you might get at Spring Harvest.

    quote:

    Yes, but the people I know would say that therefore science and religion need to be kept seperate. Teach science in science classes, religion in RE and church. That attitude wouldn't generate the result of this poll.

    MORI have clearly done something extraordinarily strnage to get that result. I'd have expected MORI to be far more professional than that, most people on this thread could have organised a better poll than they managed. Perhaps that's why it was never used in the programme, and isn't on the MORI website - they realised it was a load of pants.

    What about 30% being the people who want creationism taught combined with people who think you don't have to get into it (i.e., evolution) at all?

    There are those people who think that if you're not going into science, most of it is a waste of time ("When am I going to need this, anyway?"). Then there are those people who think biology is all about memorization and even though evolution unifies and makes sense of a lot of the random information, it's not worth the potential controversy. These people seem to design at least some of the biology curricula I've run into.

    We had (at 'A' level) lots of Ecology, Marine Biology, Genetics and not too much to dissect (rather than 'a dissection a day' that Dr L. gave you at Leeds). And re. 'Krebs', etc. I was so impressed with myself when I learnt 'Respiration' that I don't have unhappy memories!

    I take Karl's point, that biology can become rote learning - and has for some people - as has probably every subject when taught badly. I'm just surprised if that's a particular problem for biology, and explains much back-lash against it.

    BTW, I've always wondered how the first Ribonucleic acid/protein structure first got together. I think there was something done by Eigen on this.... but I can't find it at the moment.....

    Outr A-level biologu was the exact opposite of that, for at least two reasons.

    First because to do biology properly you need to actually look at living things, in the lab and most of all outdoors. You can't learn biology entirely at a desk any more than you can learn football without playing it.

    Second because things were being discovered so fast that, more than any other subject, we were told "this is what the tetbook says, but now we know..."

    We somehow missed one of the gems from the Dover trial on the way through. Under oath in the court trial, Behe gave an estimate of how long it would take an irreducibly complex phenomenon to evolve. This was based on the paper Simulating evolution by gene duplication of protein features that require multiple amino acid residues by Behe and Snoke.

    The conclusion of this paper is that "We conclude that, in general, to be fixed in 10^8 generations, the production of novel protein features that require the participation of two or more amino acid residues simply by multiple point mutations in duplicated genes would entail population sizes of no less than 10^9." Two or more amino acid residues needing to be fixed pretty much is the definition of irreducible complexity.

    There are several simplifications in the above paper that make it an upper bound - it only goes into point mutations, meaning that it doesn't allow for intermediate steps (both mutations have to happen at once), it doesn't allow for mutations by transposition (it only allows for point mutations), it doesn't allow for recombination, and it strictly limits itself to asexual mutations. In short, the mutation rate is kept down.

    This was then applied to Behe's example of irreducible complexity - the disulfide bond. Two specific point mutations in a prokaryote.

    In short, by Behe's own mathematics, in a population of 10^9, it will take 10^8 generations - or 20,000 years for this irreducibly complex mutation to happen.

    Unfortunately for Behe, a ton of healthy soil is estimated to contain more than 10^16 prokaryotes (or ten million times as many as Behe's example uses). This means that in a ton of soil, such an irreducibly complex mutation happens every 2*10^4/10^7 = 2*10^-3 years - or five hundred irreducibly complex mutations happen in each ton of soil in a year.

    Let me repeat that. By Behe's own research, without outside tampering a ton of soil produces an irreducibly complex mutation group on average more than once each day.

    Although, in fairness, you'd be in trouble as soon as you hit the less numerous metazoan eukaryotes - a fairly important stage of evolution.

    I think the flaw is in the calculation of the mutation rate, and allowing for point mutations only. I doubt many novel proteins occur by slow accumulation of point mutations, even in bacteria or protozoa. We have examples of drug resistance pumps in malaria, for instance, that appeared quite rapidly after the introduction of chloroquine.

    Unless Behe argues that was the work of some malevolent intelligent design.

    Yes but most of (perhaps all) of the fundamental biochemical pathways exist in bacteria. So I suppose they could have all evolved this way!

    There is very little added in eukaryotes - and much of what seems unique to eukaryotes, such as a lot of the nuclear proteins, may be descended from prokaryote ancestors that are lost.

    And almost nothing in metazoans (some bits of sterol synthesis?)

    Green plants have a large chunk of pathway connected to making poisonous things and wood. And a few fungi have systems for digesting them - but they look relatively recent and aer probably retrofitted from other pathways.

    Granted there may be little difference between protozoan eukaryote protein expression and bacterial.... and little between protozoan and the simplest metazoans.... but once the metazoans start getting a bit more complicated, I imagine there's a fair list of new proteins.

    I didn't mean just the initial jump - I meant from thereon up.

    It's a right dog's breakfast - with 69 percent saying evolution should be taught in schools and 44 percent saying young earth creationism should be taught, that means there are people saying mutually exclusive theories should both be taught. All this poll shows is that people have no idea what they're talking about.

    (Which, of course, is where ID comes in, as this alternative ID FAQ so concisely shows.)

    Brand new, there seem to be fewer than we used to think. What there are tend to be structural - very few new synthesis pathways.

    Just how few really new ones, of course, depends on which ones we think are "new". For example all the various eye crystallins seem to be derived from enzymes - are they new proteins or not?

    Why would anyone want two mutually exclusive theories to be taught in science classes? The only people who claim to like this idea are the 'teach the controversy' crowd, and I just cannot believe that fifteen percent of the British population fall into that camp. It's a very artifical stance, very dependent on American constitutional politics, and Judge Jones was very clear on its lack of legs.

    I don't see the problem with teaching two mutually exclusive theories. It is probably unusual to be teaching on areas with competing, well evidenced theories before graduate level in biology - but in Geography or Sociology I would think it's more common at secondary/high school level.

    (One can argue that the science behind ID is already taught - in that the complexity of life is taught in all it's glory. Anyone wishing to deduce that is irreducibly complex can do so.)

    Any serious teaching often has to discuss competing explanations. "So-and-so says this, but Thingamujig thinks that" has to be part of education. How on earth else could anyone ever teach literature or history?

    Biology currently has more of these than other sciences because it is developing faster. Some of the real controversies about evolution or the history of life on earth ought to be mentioned in school - for example what killed the big dinosaurs? I think I remember allopatric vs. sympatric speciation being discussed in the 6th form, pre-university.

    At university there are plenty of current or recently past approaches to evolution which ought to have arguments presented on both sides. The relative importance of neutral evolution and selection. Punctuated equilibrium. Can we describe evolution as "progress"? Cladistic and other approaches to systematics. Does group selection happen? Are there real distinct ecological communities? Are more diverse ecologies more stable? Stuff like that.

    However, neither YEC or ID are scientific explanations that compete with neo-Darwinism. At university they might have a place in a historical approach to evolution, discussed alongside Lamarckism and so on. You wouldn't want to leave out Gosse, and the brief period in the late 18th and very early 19th century when flood geology was taken seriously by naturalists led directly to the discovery of the ice ages. So they belong in a history of science course, not a genetics or an evolution course.

    And, in the name of controversies in a teacup, we have a political apointee in NASA who has been censor them.

    quote:
    In an e-mail message, Mr. Deutsch said that remarks about religious views on the creation of the universe sent last October to a Web designer working on a presentation on Albert Einstein were "personal observations" and never were reflected in the material that was posted online.

    "We are both Christians, and I was sharing with him my personal opinions on the Big Bang theory versus intelligent design," Mr. Deutsch wrote to The Times. "What I said about intelligent design did not affect the presentation of the Big Bang theory in the subsequent Einstein Web story. This is a very important point, because I have been accused of trying to insert religion into this story, which I was not trying to do."

    source

    What he was trying to do was get the word "Theory" inserted after every mention of the Big Bang.

    Scientifically defensible unless placed in context:
    quote:
    The Big Bang is "not proven fact; it is opinion, ... It is not NASA's place, nor should it be to make a declaration such as this about the existence of the universe that discounts intelligent design by a creator."
    His defence appears to be that he failed.

    Chalk one up to the Wedge Strategy's five year goal of "To see the beginning of the influence of design theory in spheres other than natural science."

    Thereby showing that creationism has little to do with the gospel of Christ. One can be a creationist - and a devout Conservative Jew or Muslim ... and deny Christ. And one can be a non-creationist, and fervently believe the gospel.

    Easy Peasy [Smile]

    Tholins [Smile] and a bolt of lightning or two, [Smile] A religious interperetation of this would be "Lightning = The shekinah" and "End result = act of creation". As for timescales, when the old Gorah can be said (By creationists) to have maintained that Gd made the universe in six days, (That is 144 hours). The age of the actual universe being 14.4 Bn years old is a bit of a coincidence. Creationalists have missed something I suspect.

    I think it fair to say that the literalists who deny what Darwin observed, (Called evolution) and claim that we are talking 144 hours in human time scales are actually missing the intriguing content of the creation narrative, completely.

    I personally feel the entire Creation v Evolution debate is a red herring because it misses the point. "Intelligent Design" as presented now does not present the questions that should be asked. Nor does it approach the subject with a heathy scepticism, or imagination. On the other side of the coin, Atheism seems to discuss all this in terms of totally random events, Why does tthe notion of a belief in Gd and evolution have to be incompatible? Ewhich is fine, but serves the otion of their being no Gd,

    Which in itself fails to ask the question "What actually happened". to approach a subject with the intent of excluding a possible explanation is to limit possible answers to questions. Especially when there is nothin in the Torah (Bereshyth in particular) that denies evolution, if anything a closer reading hints at otherwise, which is intriguing.

    Of course Atheism discusses things in terms of random events. If you are an atheist, you believe that there is no God. But not everyone who believes the theory of evolution is an atheist. (Indeed there are many who take the view that an honest study of the world is an honest study of God's handywork - and the part that most offends me about ID is the blasphemy involved in almost all the proponents lying about God's handiwork).

    You mean "Gd of the spaces". What I find offensive about ID is Gd is plonked in said spaces and then said to be omnipresent, which I am sure you agree is a paradox.

    The truth of it is that evolution happened. What is wrong is people take a medieval view of the Torah, and claim the text said "Six literal days" or others say "It is a metaphorical fantasy" (Often while in all good reason objecting to things done in the name of the bible, like denying Evolution happened)

    But you have to understand the text from the viewpoint of those who first read it. We are talking about the evolution (There is that word again) of a cyphered language with multiple meanings attatched to each single word. It is based on a very complex narrative method. to say "This says Gd did it in six literal days" is incorrect. From the stanpoint of the narrative yet alone any observation of how things are.

    If someone says "Gd did it because we have no explanation from this point" then that is intellectual laziness.

    If someone says "But we must exclude any Gd behind it regardless of any evidence for or against" then that is dogmatism,

    The truth is no one fully knows, it could be emergent properties from brownian motion, then again it may have been "assisted". Of course the most unsettling possibility is something along the lines of the anthropic principle. Where "Gd is what seems to have emerged"

    But these philosophical issues aside, I find upsetting that an argument in such philosophical debate results in well evidenced facts (Like most of the observation of what we call evolution) is regarded as "Herecy"

    I mean do people say that the sun rotates around the earth because the bible may have hinted at it (Actually it didnt)?

    Galilaeo had hassle from Pope Urban on that one.
    and the Earth rotates around the sun, as Galileo observed.

    I think this is what I find so irritating. People misread a text to make it dogma, then deny reality, Nowadays those advocating reality seem to fall into the same bad habits. "Oh we cannot have this or that possibility, it is herecy"

    I dont think the debate is really about the "history of everything" it is about people being told to believe what others tell them.

    why is the idea of a Gd and Evolution at the same time icompatible? the human predisposition to polarise everything perhaps? to dogmatise perhaps?

    There is not a lot wrong with free thinking I suspect [Smile]

    Well have a tendancy to post things like that because there often seems to be very little but dogma in much of these debates.

    Macromolecules tend to "line up" because of states they are in due numerous factors. DNA is a chicken and egg question though. To get DNA you need a number of proteins to assemble the fragments (Okosaki Fragments) and you need the amino acids to make up the proteins and bases of the DNA. (As in the fragments and the amino acids that make up the peptide chains in the proteins).Protein synthesis involves ribosomes, pretty complex macropmolecular machinery by all accounts. It is a chicken and egg situation, Where did complex proteins like Ribosomes come from? or the proteins needed to synthesise DNA (Ligases and so on) and edit the DNA (Restriction enzymes) etc etc.

    What assembled the DNA in the beginning? the whole gamut of proteins and enzymes required needed DNA or at lease RNA to begin with.

    I imagine the ID theorist would say that this little problem "proves Gd did it" (Well no that is the Gd of the spaces, it does nothing of the sort)

    Your Darwinist would argue that it all occured randomly (Again this explains nothing)

    So I tend to give the debate 0 out of 10 for lack of imagniation.

    I was sort of hoping you would yourself have a suggestion beyond my "Tholins + Lightning" line (Which was a bit cynical about the debate, not you, if you took it that way I apologise [Smile] )

    A possible clue lies in methyl groups, carboxy and Amino ends and disulphide bridges. Which seem to form the components of the mechanics of all this. but if you get the raw materials (Numerous meduim sized molecules with above forming part of them) nothing happens ulnless you have them in the right environment in terms of energy (Heat, etc).

    In these debates no one goes beyond the apparent gap between small molecules like methane (Which becomes a methyl group in larger molecules) and macromolecules like Ribosomes.

    It is all space filling "Randomness" or "Gd". So I in frustration say strange things like "Tholins + Lightning [Smile] " because it is here where the gap seems to be filled with something other than just "Gd" or "Random".

    For me it is the emergent properties, that is the potential for small molecules under certain conditions to lend themselves to forming larger molecules of a certain configuration. As such the complexity emerges under certain conditions.

    I suspect the concept of "Random" and "Regularity" is missing the point. Just that molecules under certain conditions will often form certain patterns which get ever more complex as molecules get bigger.

    the only thing I can say for certain is that the presence of certain molecules and the presence of various types of energy seem to make this pattern emerge. Hence my throw away remark.

    Flash bang into a certain orange gaseus cloud seems to be where it happens, How it happens? well that does require an explanation above and beyond just "Gd" and "Random" as these molecules are obvioulsy forming as a result of permuations of various natural laws and states. I suspect it is the origin of these laws and states one needs to ask about. until then it is gap filling. Sadly [Frown]

    There's a difference between something is truly random -- that is unpredictable even in principle -- and something that is quasi-random -- that is, giving an appearance of randomness because of the complexity of the process. My understanding is that there is dissent among physicists about whether quantum-level phenomena, including radioactive decay, are truly random or not. The idea, for example, that subatomic particles hold state (in some unspecified way), and act according to complex relationships involving that state, is one that has come into and gone out of fashion over the last 50 years or so.

    My point is that to assert that, say, radioactive decay is truly random is to make a different kind of assertion than that it is too complex, or whatever, for us to predict.

    quote:

    Really? I'll be you a pound to a penny that you can leave a pool of salt and water laying around for a billion years and you'll never get anything more complex than saltwater.

    What's more, you're going to need a lot more than one self-replicating molecule. If that's all you've got, you'll just end up with the whole world filled with the same molecule.

    I tend to agree with mdijon (if I've properly understood what he's saying) on this one. In the 19th and early 20th centuries, people seeking a non-design explanation for the emergence of life thought that the challenge was explaining complex macrostructures, such as the mammalian eye. But, in reality, what goes on in every nucleus is astronomically more complex than any macrostructure. Not just a bit more complex, but hugely, overwhelmingly more complex. The challenge now, as I understand it, is to understand how we got from a trivial self-replicating microstructure (whatever it was) to the incredible genetic machinery of the cell.

    I think it is the difficulty involved in doing this that has led materialists like Francis Crick to speculate (without evidence irony, so far as i can tell) that life was seeded on Earth from space.

    I have to admit having found "Natural selection" as opposed to "Natural adaptation" somewhat telling when it comes to the sort of Darwinism Richard Dawkins preaches.

    Getting past the issue of semantics is indeed quite important. Like most biologists seem to inadvertantly anthropopmorphise DNA by saying "The genes decide outcome X or Y" And while they dont actually mean it like this, the causual reader would see this implied statement as anthropopmorhic.

    Anyway the question should be "Is randomness" a term used to describe Brownian motion for example. Which is by nature "random" but often regularity seems to emerge from it.

    A cool answer to Mdijon's question would be interesting, please tell [Smile]

    Does it involve emergent peoperties in your opinion? [Smile]

    Well yes and no really. I mean radioactive decay is basically brownian, and as such you would be right in that things would inevitably happen from something brownian, but the question is, what makes brownian motion have this property? what rules? Rather than just fill the gaps with "Randomness is ok, things just emerge".

    Why not ask "Why does this happen?" I think the physical laws involved are reasonably understood, just very complex. But even chaos theorists would admit that in some systems a common outcome (Evolutionary convergence being a good example) would eventually appear, rather like every polyhedra ends up pretty much as a sphere as it gets bigger with more facets.

    Well with spheres and shapes the answer is quite simple, with molecular interactions and the somewhat interesting laws the atoms they are made of seem to obey it gets a bit complex.

    but does anyone ever ask "Where did the laws of physics" come from? Newton, Einstein, Shrodinger, and so on, they *discovered* them, they didnt write them. The laws themselves on the day to day physical level act like computer programs, almost totally predictable, on the subatomic level well not so. We get into quantum mechanics, which seem to delve into the realms of unspeakable strangeness (As in wierd not quark) that has people asking interesting questions. It is curious, what is wrong with curiosity?

    I would rather turn my brain inside out....

    and percive the universe as having the center of it and the outer horizon of it occupying the same space, (Where Einstien and Shroedinger actually agreed but never publically, so above so below says the quabbalist [Biased] Big as in univers small as in quantum mechanic are unified after all. [Biased] ).....more questions....

    Than ponder the idea of filling gaps with Gd or with randomness.

    The sad thing about these debates with Darwin v Faith, Creation v evolutiion. is that curiosity seems to be suspended, and replaced with statements most of which are without any scientific proofs.

    Hmm intriguing [Smile] Monotheism emerged because of the very things you say ("Do not multiply entities beyond necessity"). I suspect this will be another debate. (And fascinating one).

    what I am saying is that the "Gd of the Gaps" seems a bit of a paradox, I know you are talking about strict definitions and beliefs, that is you either believe there is or is not a Gd, Belief in a Gd seems to be presented as a belief in an omnipresent being, which contradictied by this being being relagated to smaller roles and smaller spaces ultimateley. Which puts ID and creationalism on a bad footing when that argument of the gaps is used. Myself I dont hold to ID or Creationalism anyway. both are just dogmas or circular arguments to assert a dogma.

    I think Urban was a bit naughty leading Galilaeo to believe that he entertained the ideas of Kepler was it? And then started challenging Galilaeo over the observations. I think Galilaeo was sort of commenting on the inconsistency of Pope Urban.

    We can debate this for ages, I am sure, but the fact remains that the Earth rotates around the sun, as part of a solar system. (It is the notion of a sol-ar system that was at the core of the debate, as opposed to an "earthar" system)

    .

    I simply reject creationalism because it is a very superficial reading of the text made into dogma. A dogma the gets so ingrained that 4 billion years worth of physical evidence in fossil records and geological processes is ignored.

    I Reject ID because, it is all soundbites debating methods and spin, very little substance.
    I have no problem with someone questioning scientific dogma, (I do that a hell of a lot myself) I do have an issue with people presenting arguments just to assert a pre existing dogma.

    The problem I suspect is in how the western or hellenic conceptualisation of "The fall" and "Original sin" seems to involve another literalist reading with repsect to free will and questioning. The modern edifice of religion is built on the notion of "unquestioning" unless "Questioning" asserts the "Unquestionable Dogma"

    The bible as it is now presented and read, seems to be used to prop up this "do not question" ideal. However earlier variations of the text, as I suspect you know, did not do this.

    I think the real issue between science and faith is hat faith as currentley manifested seems to be about not asking questions. But the whole reason for religion itslef is because many thousands of years ago, people asked questions. Like "Why so many deities why not have a singular Gd?" (Ask Akenhaten [Biased] )

    That's the process that's statistically more and likely to happen, the longer it's left to get on with it. Now, one can readily imagine all sorts of intriguing structures resulting — intriguing to a chemist, that is, but not self-replicating.

    But on the other hand, as Raptor said, it would only have taken one self-replicating structure to form...

    I don't think that's a correct way of viewing molecules.

    They don't behave like self-replicating evolution driving particles unless they first start to make up a biological life form.

    If you leave amino-acids in solution, peptides will never form. Not even in small concentrations. And the "millions of years" argument doesn't really wash, since you've already had however many avagadro constant multiples of molecules interacting without anything happening.

    On the other hand, DNA does spontaneously polymerise - up to a point - and so I think most theories on this argue that DNA came first. RNA is probably necessary to catalyse polymerising of DNA oligomers.

    Eigen (I seem to recall) did something on this - and there was some older work on clays with embedded ions carrying ions as prototypes for DNA polymerisation.

    But even if those details get overcome, I agree with Sophia's (later) analysis, that it's a hell of a chicken and egg situation.

    If there's no space, Ken, a link might be good?

    I am aware of this theory, but to the best of my knowledge there is a huge gap between what has been demonstrated in the laboratory in this area (ie., not a lot) and what must actually have happened in the distant past.

    Which leads to my main point:

    Nobody's very keen of `God of the gaps' explanations for anything. But how big must the `gap' be before it becomes reasonable to consider whether there is, in fact, some creative influence at work? Getting from nucleotide soup to DNA is a helluva big gap, really; it's far easy to see how we can get from cells to people, in my view, than how we get from soup to cells.

    Is there something instrincally unscientific about looking for creative input in the process of evolution?

    I think you will find Mdijon is correct, there may be a flaw in your argument when it comes to how complex molecules form.

    Nucleotide bases are iitially amino acids, Sugars generally require a bit of tweaking from larger molecules to produce. Amino Acids are perhaps the best place to explain this actually Ammonia and a simple acid linked in the middle with a carbon atom (And a hydrogen atom off to the side) they are made into a single link in the backbone of a peptide chain when you get the ammonia molecule as the amino group, the acid as a carrboxy group and the carbon atom joining them "Back to back"

    So you get H3N-CH-COO. (Usually denoted as "R") The Amino group and the Carboxy group can be also Joined together "front to front" with the by broduct being water. This makes a chain, a polymer. Where CH is you get other similarly small molecules joining up to form an amino acid. there are twenty different small molecules that link up to the CH making 20 different amino acids, which is what makes up a peptide chain.

    But to join them front to front usually you would need a ribosome, which is basically protein, which are invariably made up of, errm peptide chains.

    you see this is the problem what we currentley identify as "life" as in macromolecules needs macromolecules to form.

    Chicken and egg.

    So what most microbiologists have done is look at how simpler polymers can form without pre existing macromolecules. This is why Tholins are so interesting, but while they may be "Precursors" to self replicating molecules they could only theoretically form into self replicating molecules under certain conditions.

    "Under certain conditions" tends not to involve long periods of time, rather it can simply involve a bolt of lightning. (I believe one attempt involed arcs of electricity to get the tholins doing something)

    It is fair to say that amino acids being "Small" molecules, made up of even smaller molecules that you find in GSCE text books on chemistry are very much a part of biology as well as chemistry. Myself working mainly with genetics, I often find that it is more chemistry than discussing inheritance etc.

    A "thicker soup" as you described it would really not be all that much thicker, and would probably not involve sugars. Because the thicker soup would not be at the stage where large and complex molecules like Enzymes and Proteins (Enzymes are proteins, they usualy convert one compound to another) are around to do the donkey work, you need to form these somehow before you get onto self replicating molecules.

    The big mystery (And why people spend millions on things like the Cassini-Huygens probe to Saturn's moon, Titan, with an atmosphere full of tholins)
    is how we get round the chicken and egg, like why did this happen on earth and not titan, Temperture must therefore play a part given that Titan is really a cold place.

    I would much rather see what comes out of that than just sit here thinking of a thicker soup acted upon by Gd or Randomness. It is an important question, to determine how we circumvent the processes that require pre existing macromolecules.

    Ultimately the question still remains, even if that is sussed out, what made the laws by which all this happens in the first place? How did they happen. Curiostity says "Well lets figure that out"

    Basically, the approach of science is to try and narrow the gap. It works from both sides. Studies of pre-biotic chemical soups (eg: the chemistry of Titan Sophia mentioned) and what sort of chemistry happens in them give us hints as to how the more complex molecules needed for life could start off. From the other side, it's clear that even something as relatively simple as the DNA of an average bacteria is signifantly more complex than what's needed for self-replicating molecules. So, there are scientists working backwards to find out just how simple the system can get and be self-replicating. Even though we have no really good idea how the gap is bridged, we are beginning to get to the point where we know approximately how big the gap is. Inevitably, the gap will close further.

    Well my throw away Remark earlier, was to illustrate a point I have about how people read the religious texts. Think about it, in the days when the bible was written (Thinking of the Torah which would be between 1200 BC and 710 BC when Hezekiah came along and codified it), Lightning would mean the Shekinah, or Presence of Gd. In fact many descriptions of the shekinah seem to involve natural processes like lightning.

    The question again is "what laws of physics make bolts of lightning" (The induction of static usually). What makes the laws governing static? what makes the laws governing that, even if it all gets tied up and explained neatly, the people who wrote the narratives in the Torah, or other writings of the day(s) would not be tinking in terms of "What is behind this, and then behind that" and then say "we cannot explain it it therefore must be Gd" Rather they concluded that behind it all was a something that would one day be better understood. (This is what all the prophesies speak of, knowing this Gd).

    Even as late as the 18th and 19th century the "divine" idea of "the spark of life" bringing "life" somehow captured the imagination. They knw nothing of tholins then. But have you ever read Mary Shelley? Who wrote A Modern Prometheus, alias Frankenstein?

    All inspired by a rather strange nighmare and little chats at the royal institute with people zapping dead frogs legs with electricity.

    It isnt a question of Gaps it is a question of perception, The old testament narrators did not have the benefit of science to explain what they saw, at the same time I am convinced that science seems to miss a few observations that seem to show up in old writings. Because the word "Gd" is attatched to the text, we find "It is therefore false" Rather than a study of what these cultures were capable of.

    Take navigation, they didnt rely on sattelite navigation, it was looking at shadows, or rather the length of them, usually when on the sea or in the desert. You would at some point grasp how the solar system works, like where the sun is. But rely on a compass and a few thousand years on the church says "The earth is at the center" (Duh!).

    I think ancient people fail to get the credit they deserve often. I think simply rejecting belief systems in the sneery manner some do (Like Dawkins does) is not helpful. They perhaps knew more about the solar system than Pope Urban did, And in navigation, then, across a sea or a desert, it would have been a matter of life and death.

    It is about interperetation, not gaps.

    Maybe it will, although I'm less certain that it's inevitable.

    That isn't really my point, however. What concerns me is why so many people see it as unscientific in principle to try to determine whether the gap was closed by a creative act.

    I can see good pragmatic reasons for objecting to this endeavour -- that it probably wont lead anywhere, that creationists will think its about them, that it will be done unscientifically, or that we just don't really have a clue how to start.

    But that anyone should believe such an attempt is a priori unscientific perplexes me.
     
    Posted by mdijon (# 8520) on :
     
    One can construct a hypothesis and test it; perfectly scientific.

    The difficulty is that ID type hypotheses are often the null hypothesis for another study.

    eg. A biochemist might start with the hypothesis "DNA can polymerise spontaneously under certain conditions."

    One does this by writing the null hypothesis - perhaps in a more focused way for the particular experiments "In this range of clay/ion concentrations no spontaneous DNA polymerisation will be observed."

    One then either rejects or retains the null hypothesis.

    The problem is that retaining the null hypothesis can't be viewed as proof of something. It can only be regarded as absence of proof for something else.

    I think what ID would need to do is come up with a positive hypothesis - not "No evidence of a mechanism for x part of evolution will be found" - but more "Evidence x of creative input will be seen if y". The difficulty is, I'm not sure there is any such hypothesis. Hence it is very difficult for ID to stop being a philosophical gut reaction based on the complexity of the world, evolutionary theory and (as you say) "the gaps". Similarly belief in God.

    Well, rejecting a null hypothesis is supportive of some other hypothesis if there are only two hypotheses which are possibly correct. I think that's part of the ID problem. If you start from the assumption that either we have to accept the neo-Darwinian model as it currently is, or some form of ID, then anything that weakens the neo-Darwinian position strengthens the ID position.

    The problem is that, from a scientific perspective, we have no a priori reason to assume that we must accept either some ID model or some neo-Darwinian model. There could be any number of design or non-Design things going on that we know nothing about as yet.

    So, to that extent, I agree -- showing some weakness or other in the neo-Darwinian proposition provides no support at all for a design proposition.

    Like you, I wonder if formulating a positive proposition to test is possible, even in principle. My gut feeling is that approaches based on information theory are most likely to be acceptable, but even then there is scope for arguing whether the presence of certain informational signatures is really indicative of intelligence or not.

    Nevertheless, I wouldn't reject scientific investigation in this area on principle, despite it being difficult to do in practice.

    That's not what I'm saying. I'm not suggesting that the null hypothesis approach applies to ID vs Darwin vs nothing as a whole - rather that it applies to the steps along the way.

    If someone hypothesises a particular progression of species through the ages - that is a testable hypothesis. One can make a prediction that the distribution of fossils will not be random as one proceeds through geological layers. If it isn't random, you've rejected the null hypothesis that it would be random.

    Similarly, one can make a hypothesis that phylogenetic trees are constructable - and reject the null hypothesis that they aren't.

    And those hundreds of steps can imply a unifying theory regarding evolution.

    Each can be written in a tightly focused enough way to not require a priori considerations of theory in order to test.

    I don't know what those are for ID. It would need to be something along the lines of "In a certain setup, the impact of intelligent input will not be determined in that x/y/z will be random, having controlled for all other factors that might generate order".

    It's not going to happen, though. And it would be rather akin to the kind of studies medics do to measure the efficacy of prayer.

    A modern day Tower of Babel.

    But perhaps ID works rather better as an argued philosophy, rather than a science?

    Jumping back into the chemistry bit of the discussion, I'm not so sure that it is all necessarily a Chicken & Egg Show.

    Just because ribosomes are the only things catalysing a particular reaction nowadays (and I shouldn't have been so lazy as to omit to mention the need for a catalyst), doesn't mean that something else, say off-hand a clay mineral, couldn't have been doing something similar at a crucial time in the past.

    This is still very much at the testing stage, as far as I know. However, it's something of a challenge to the sort of argument that claims that it is in principle impossible to conceive of the ingredients of biological systems arising other than from already extant life forms.

    Ideas based on tholins are another version of the same challenge, really.


    P.S. Can't remember who mentioned sugars, but yes, they would be the weakest evidential link in my hypothetical soup brew.

    Except that last week's New Scientist noted that clay particles form through the degradative action of bacteria on soil - but I get the principle.

    Incidentally, I think it's generally held that RNA came first, acting as both a catalyst and hereditary material, perhaps assisted by short chains of amino acids or phosphorylated cofactors, and both proteins and DNA turned up later. So possibly you only have to account for the emergence of one group of self-replicating molecules.

    It's still a chicken and egg - you're suggesting an egg substitute to get the show of the ground.

    Of course, to synthesise protein you need more than just the ribosome - you need transfer RNA to tag the amino acids as well. So it's not so much chicken and egg - more like two chickens and an egg.

    But granted, if someone could show that clay - or metallic ions - or some other inert substance could substitute for ribosomal RNA, that would be a big leap forward.

    Given how specialised ribosomes are (encoded protein as well as RNA) I think it would be a push... but stranger things have happened, I guess.

    If some (fairly common) ion on a mineral surface, or similar, could be shown to catalyse (or in some other manner enable) some part of the pathways necessary for life as we know it that would be a major step forward. Even if that mechanism was very inefficient compared to the ribosomal RNA, as long as the process that would incorporate it could eventually generate ribosomal RNA it would be OK. It would allow the rest of the chicken to start to form without the egg, or is that egg without a chicken? Just because the system currently uses a highly efficient system of ribosomal RNA, that doesn't mean that that's the only way it could work. Which is part of the trap that the ID concept of irreducible complexity falls into - just because a system currently requires several specialised components doesn't mean that a similar (though less efficient) system couldn't have used something else in place of one or more of those components; so long as it's possible for a new mechanism to develop that a) replaces a component and b) is more efficient then evolution will do the rest.

    Doesn't have to be RNA, though, there are various plausible scaffolds of other, simpler self-replicating molecules which could kick the whole thing off. They wouldn't be here now, any more than London runs on a collection of dirt tracks and wooden boats.

    This is still very much at the testing stage, as far as I know. However, it's something of a challenge to the sort of argument that claims that it is in principle impossible to conceive of the ingredients of biological systems arising other than from already extant life forms.

    Ideas based on tholins are another version of the same challenge, really.

    Perhaps, but that didn't stop the big bang theorists.

    I'm not sure what kind of self-replicating molecules you are thinking of that might start the thing off - they would need to interact with RNA/DNA/protein synthesis in some way to "start the thing off" in any sense.

    And I don't see why they wouldn't be around today - much of the evolutionary tree is, in some form or other.

    I think that's right. I'm suggesting it's a real impasse though even thinking of a fairly inefficient mechanism - but it's not my area and for all I know someone may have a good experimental window on this in the last few years.

    Interesting to see the creationists feuding. Seems that the international branch of Creation Ministries International is actually honest (if misguided). Not only have they changed their name from the Creation Science Foundation (because they didn't do science), and not only did they correct Hovind, but Ken Ham (and Answers in Genesis) have fissioned away because they did not want to be "subject to an international representative system of checks/balances/peer review involving all the other offices bearing the same 'brand name'". In short, Ken Ham appears to want to say whatever he wants to advance the cause of evolution...

    Answers in Genesis appear to have removed the reply to Hovind - but Creation Ministries International have kept their copy.

    Creationism is, I take it, an umbrella term for scientific theories which try to explain the mechanism by which God created the universe.

    If a particular set of such theories is falsified and discredited, surely no-one at all should accept them? Such falsification has no necessary bearing on the faith position that God did indeed create the universe — somehow.

    You'd think so, wouldn't you? But IME, very few creationists accept that it has been scientifically falsified. This is for two reasons:

    1) Listening to LCWs (Lying Creationist Weasels) who twist, manipulate, bend and generally misrepresent the scientific evidence.

    2) Not listening at all.

    I find that most creationists can't cope with this. For them, if God didn't create supernaturally, then He didn't create at all.

    Re the OCR GCSE syllabus: I wouldn't let OCR off the hook so easily. I suspect that this is being used as the thin end of the wedge by the creationist movement. They want to get recognition that creationism is science - so allowing it in science classes is dangerous*. The problem is that having it in the syllabus makes it much easier to misuse. There will be a few teachers and pupils who will try to make propaganda for creationism in class. Some teachers will be put under discrete pressure to cast doubt on Darwin's theory, and some pupils will be told what to say in class.

    This idea presumably has some grounding in an idea of scientific debate. But you cannot argue against creationism on scientific grounds - it is a belief, not based on evidence. You can only effectively argue against creationism on religous grounds, by showing that it is both unnecessary and dangerous.

    The whole idea is at best pointless, and at worse prone to misuse. So why is it there? Who was pushing the idea? Can anyone provide information on what was really going on?


    *Of course, since creationism is not christianity, it should have no use in RE classes either, unless it is put forward as a religion in its own right? How about creative fiction classes?

    Well, if the OCR are serious about doing this right then they really do need to do it right. That is, make sure that the syllabus covers the whole issue - so not just Creationism/ID and Evolution as just an either/or scenario. But, the fact that a very large number of practicing scientist who are Christians (not to forget Christians who aren't practicing scientists, and the equally strong groupings among Islamic and Jewish scholars) that see no conflict at all between science and religion. Teach the whole lot, and in the process make it clear that this idea of a conflict is one that is only really held by the minority on the extremes - both the ID Creationists and the Dawkinesque Atheists.

    quote:

    I don't know whether the ID Creationist movement in the UK is strong enough to be a source for such an idea. But, they'll certainly try and take advantage of it. If the OCR go ahead with the idea, then it's beholden to the rest of us to make sure that the result is well balanced. It doesn't help our childrens education for us to do anything else.

    What OCR is intending to do is to give the IDers what they claim to want - teaching the controversy. In other words, including on the curriculum why creationism is wrong and stupid - and approximately comparable to the Flat Earth theory.

    If teaching people that creationism is discredited gibberish and here's why it's gibberish is the thin end of the wedge, I don't think it's a creationist wedge.

    There are indeed different infinities. The set of integers is infinite, as is the set of real numbers between any two integers. So the set of real numbers is an infinity of infinities.

    Well, he has a point that the findings of "creation science" (or, indeed, Intelligent Design) are ignored by mainstream science. The vast majority of scientists, by necessity, concentrate on their own fields. Very few have time to engage with other fields, let alone areas of study that aren't even science (but try and pretend like they are). At least professionally. You'll always find plenty of scientists to engage in discussion of other stuff over a beer in the pub.

    quote:

    I don't want to get into an evolutionary wrangle, but I have a lot of trouble reconciling creationism with ordinary rational thought.

    Creationism starts from a particular position. Namely that the Bible is the inerrant, directly inspired Word of God and that as such it cannot lie nor decieve. Creationists read the opening chapters of Genesis as literal history, and consider that any other reading casts into doubt the trustworthiness of the Bible to reveal the truth about God, and hence undermines the entire Christian faith. That is, in fact, a rational position to take; though not the only rational approach to Scripture.

    From that starting point you're stuck with a very narrow range of rational options:
    1. The Earth was created in 6 days approximately 6000 years ago as recorded in Genesis, but in such a way as to appear very much older to scientific enquiry. Thus, belief in God and the truth of the Bible is a matter entirely of faith.
    2. The Earth was created in 6 days approximately 6000 years ago as recorded in Genesis, and contemporary science is in error. This is the view of most Young Earth Creationists, and the primary purpose of Creation Science is to point out the errors in conventional science and work towards correcting them.
    3. The Genesis account is of some form of recreation or reworking of a much older earth that somehow became void for God to work on. Scientific evidence of an old earth and evolution relates to this earlier earth. This is primarily supported by a hypothetical "gap" slipped into the opening verse, which is translated "the earth became formless and void".
    4. The "days" in Genesis are actually very much longer periods of time. So, although Creation was completed 6000 years ago, it took the billions of years science reveals. The biggest problems are that a) the sequence is wrong (according to contemporary science, and logic) and b) there's no evidence of a change such that the processes of creation stopped 6000 years ago.
    Though I'd disagree with all of these views, they are rational developments of the starting premise of the reliability of Scripture. But, then again, I disagree with the starting premise too.
     
    Posted by Virginia Woolf (# 11112) on :
     
    Alan, I've seen more than one fundamentalist Christian and a few Jewish creationists talk about a variation on #4, that the days of creation ('yeom', iirc) can be translated as "indefinite period of time", such as we might say, "in his day he was a gifted pianist". As with any language there can be many legitimate translations of a word.

    At any rate, the idea these individuals had is not that creation finished 6000 years ago, but that Genesis is completely compatible with the modern scientific view ... but there are problems with translating such an old text wherein God was stating truth about the creation - but worded so simply it would be relevant even to the most unsophisticated.

    I once watched as a fundamentalist geologist used this argument to completely demolish the positions of simpler Young Earth Creationists, but they didn't seem to notice and kept repeating their positions slightly re-worded.

    I can't really subscribe to this view because there's just too much difference in the order of creation between the scientific and Genesis, but on the other hand it does seem closer to the scientific view than other creation myths from around the world.

    For example you see the basic progression of Light (big bang?), waters, dry land "gathered into one place (Pangaea?) - the waters have the fish and the land starts with vegetation, then birds, then mammals, then Man.

    So there are many variations of fundamentalist creationist beliefs, some of them quite rational as you noted, and some less divorced from evidence than YEC.

    I find it blasphemous as it makes God into a liar when he made his creation (or arguably makes him genocidal to re-make the world). The evidence that there has been life on this world for more than 6000 years is overwhelming.

    (pre-emptive apologies for what I fear is a long and somewhat rambling post)

    As long as these spades you're girding yourself with are based on real scientific research and not selective use of information to back up what you already believe to be true, I'm interested. Sadly, I haven't seen any.

    For instance...

    There was once a non-denominational preacher who would set himself up on the public square at my (yes, liberal) college. He would stand there for several hours proclaiming, in a nutshell, that the entire campus was going ad infernum en masse because of our heretical belief in such things as gay marriage, legal access to abortion, women in the workplace, smoking, drinking, pornography, and yes, evolution. Needless to say, we all found this highly entertaining.

    One of his arguments was that archaelogists had found fossilized seashells on the top of Mt Everest. Thus, we now know that the flood must have happened exactly as described in the bible, because clearly Mt Everest must have, at one time, been submerged.

    This makes a lot of sense, if you assume a priori that Mt Everest was always standing exactly as it is today.

    The trouble is that (to make a long story short) plate tectonics theory explains how the Himalayan mountains probably rose over a period of millions of years as the Indian and Asian continentaly plates collided with each other. Before that collision, there had been a seabed between them. Hence, the seashells.

    Of course, to think about this theory requires that you think of time on a geological scale, and requires that you look at a large quantity of scientific evidence that has been collected and studied over decades; satellite images of the earth, measurements based on those images, rock samples, carbon dating, etc. Whatever you want to say about evolution, there is no shortage of evidence. And it all points roughly in the same direction.

    The trouble with the fundamentalist argument about creation is that it only looks at one tiny part of the big picture and then generalizes from that to the entire creation.

    It's kinda like a car salesman who tells you that the car is in great condition based on the fact that the ignition system works (conveniently ignoring the fact that the transmission's on the verge of failure, or that the fuel tank leaks, the back door doesn't open, etc).

    I'll admit fallibility on this, but I have never seen any case for strict biblical creationism that wasn't like the one above, creatively using a few tiny motes of scientific data to make a sweeping generalization about the entire world.

    If someone can come up with an argument for creationism that looks, sounds, smells, and feels like rigorous scientific research, I'd be interested. I just haven't heard one yet.

    I don't think Young Earth Creationists are crackpots - they're not crazy, they simply haven't spent much time studying the scientific viewpoint vs the YEC. You may have read Christian tracts that criticized the standard scientific models, but you haven't spent any similar time reading and carefully considering the rebuttals of scientists .... or even what the scientists are actually saying. For example, among individuals like yourself I commonly hear the statement that "Darwin said we are all descended from apes" which isn't accurate and bears little relationship to what paleontologists actually teach.

    YECs base their belief on authority, the authority of one of many literal interpreters of the Bible - often based on a particular translation such as ye olde King James. Evidence of any physical kind isn't seriously considered because the Bible is thought to trump any evidence outside it - they pick and choose geological evidence to support the Bible - if a fact contradicts Genesis it is simply discarded.

    Scientists aren't slaves to authority, not even Darwin's, so much as they try to make sense of the considerable amount of evidence around us.

    If you were to take a beginning geology and paleontology course at a local college, Sync, and then used that knowledge to carefully consider the debates between YECs and mainstream scientists, you might be very surprised.

    Oh, I just noticed Mirrizin's post popping up, it's quite good.

    I can't speak for sanc's experience with the literature, but as a former YEC this is exactly how I ended up "changing sides" (or whatever more appropriate term one should use).

    In the beginning I read only YEC stuff on origins, and as much as I could get my hands on. I found, though, that the YEC position was completely self contained and I was dissatisfied about the level of generalization-to-absurdity that I could identify even as a YEC myself. Then I started looking at not only what the creationists said about evolution but what the evolutionists said about creationism. Then I found that it wasn't as simple as two sides I was presented for a long time and there are many more nuanced views that were not even represented in what I had been reading and studying. I also identified a lot of questions that I had never thought to ask before and found answers from every direction that I did not expect when I set out. One day it all went Bang! and I settled to where I am now.

    Reading about alternative ideas from the supporters of the ideas as well as from the dissenters taught me a whole lot that I would never have seen had I only read YEC literature. Even if everythign I read hadn't changed my mind (I know some intelligent, well meaning people who have done what I did without changing their ideas) it was still only fair to learn about people's ideas from the people who held those ideas rather than only from people with different ideas.

    I think that it is a mistake to think that it is the fossil evidence which points to the Earth being ancient. Most fossils are dated by their relative position in the sequence, so Carboniferous fossils are presumably older than Jurassic fossils because they are always found below them.
    At the beginning of the 20th century geologists wanted the Earth to be ancient so that all the processes which can be observed could be fitted in to the sequence, but it was only the discovery of radioactivity which allowed the sun to be more than 100,000 years old. Now all of physics points to the universe being ancient, and points to the Earth being 4.5 billion years old. It's not the fossils which say the Earth is old, it's the same physics which drives computers, watches etc. etc.

    Which gives me an opportunity to expose the sort of lies the LCWs (Lying Creationist Weasels) use to promote their bullshit.

    Go to any LCW website and you will be told that:

    "The fossils date the rocks and the rocks date the fossils. This is circular reasoning, therefore the dates are meaningless, the earth is young, Darwin was Satanically possessed, yada, yada, yada"

    But the truth is rather different. The process happens like this:

    1. Fossil FA is dated at between X million years and Y million years because it is always found in strata between volcanic intrusion VX and VY, radioisotope dated to X million years and Y million years.

    2. Stratum SC is dated at between X million years and Y million years because it's between the two volcanic intrusions VX and VY.

    3. Fossil FB is dated at between X million years and Y million years because it is found in the same strata as fossil FA

    Spot the difference? This, folks, is the sort of lying the creationists use to promote their nonsense. The strongest evidence that YEC is a load of cobblers is the sheer volume of lies, misrepresentations and straight invention required to support it.

    I have to agree. I think it's as much about power as it is about theology. The belief in that sort of biblical interpretation is so freqently tied up with lockstep agreement on so many other political and social issues...it's kinda creepy. I've met people who talk that talk and I don't doubt their personal sincerity, but I wonder how deeply someone has to delude him or herself to really believe it. The leaps of faith some people put themselves through are astronomical. One wonders what the benefit is.

    It's all a bit like 1984 where everyone effortlessly convinces themselves that the chocolate ration has gone up to 20g per month, rather than down from 30g per month. Orwell derived his observations from the way that Communists in the UK effortlessly went from an anti-Nazi position to a defence of Nazism in the aftermath of the Nazi-Soviet pact. If one thinks of creationism - whatever its guise - as being a political position then it is no more incomprehensible than the fibs politicians invariably tell in order to defend the party line.

    Of course, if one regards it as theology or science it is incomprehensible as both are supposed to have higher standards of truth. But if one regards it not as a disinterested investigation as to how the world works but a piece of specious political opportunism, it all makes sense. Hovind, Gish, Dembski and their ilk are laughable as guides to the cosmos. But they are entirely successful as hacks.

    Meanwhile, Kitzmiller rumbles on - Judge Jones has made it to the cover of Time!

    From the AP report

    "...[he] was named to Time's list of the 100 Most Influential People of the 20th Century, published Monday.

    Jones' likeness is on the cover along with those of President Bush, Pope Benedict XVI and Oprah Winfrey. "I was dumbstruck," he said, but he kept the honor in perspective.

    "This will pass and I will be back to the more mundane things," Jones said. "Andy Warhol said everybody gets 15 minutes of fame. ...I may be in minute 14."

    In other Kitzmiller news: Of Pandas and People is going to be reissued under another title, by the way, as "The Design Of Life", although whether this will do it any good following the mauling it got in the court case is an interesting question. Dembski has changed jobs and is moving to Texas, and Behe's statements about the evolvability of the immune system have provoked fascinating responses.

    The gift that keeps on giving...

    I was doing a little thinking about protein sequences the other day, and their relationship to evolution. (I am in the fortunate position of being able to check them against deposited experimental data).

    In the course of this I came across this site, where you can select a few haemoglobin sequences and have a program calculate a phylogenetic trees from their similarities. But haemoglobin is just one protein among milltions. There are gigbytes of publicly available protein sequence data and it is growing at an alarming rate. That is a lot of information, which any lay person can pick up and investigate with the most basic computational tools, or even by hand. We are at a potential 'Gutenbergisation' of evolutionary research.

    So the question I arrived at is: What assumptions are made in going from protein sequence data to a theory of evolution? Or in other terms, if we didn't have the work of Darwin and fossils and just had protein sequence data, would we arrive at the same model, and how quickly?

    As a starting point, I found this at Berkley
    quote:

    There are three basic assumptions in cladistics:

    The first assumption seems undesirable to me: I would prefer to look at the data and infer a common ancestor on the basis of similarity, however this would depend on being able to demonstrate the possibility of a completely unrelated sequence with gives rise to a functionally equivalent protein - a difficult argument to make.

    The third point is a question of mutation. There are lots of obvious illustrations of mutations (e.g. eye colour), but they are obfuscated by the competing effects of recessive genes and so on. It would be nice to be able to illustrate this more clearly.

    And the second point is the old question of speciation. Seagulls have an interesting contribution to make here, but I need to read up on that.

    So how big a leap does each of these assumptions involve? And what other assumptions have I made and overlooked?

    In a phrase - nested hierarchies. We observe groups within groups, a repeated pattern where there's a common feature linking one group and defining it as separate from all others; within that group, there are common features linking elements within subgroups and defining them as separate from others within the original group. (How you classify each group of groups as species, genus, family and so on is thus a bit arbitary, which incidentally makes the creationist "macro verus microevolution" distinction useless without a very tight definition of what they mean).

    There is no other way to explain this but as the result of common descent with modification - even if you knew nothing else, there is no other model that fits the data.

    (There's some good discussion about this, including some of the complications which don't make things quite as pretty as that, at Talk Origins)

    Oh - that wasn't the response I was expecting!

    Nested heirarchies are, as far as I know, the primary tool used for grouping data by similarity. Most tasks in which data must be classified into groups seems to come down to cluster analysis, which is performed by producing by merging nearby data to produce a tree hierarchy. The groups are then isolated by selecting a level at which the merging process is stopped. See for example here: (link)

    Now as far as I can tell this is a pure statistical technique, whose origins are nothing to do with biology. I had applied it to a number of problems before realising it was also used in sequence comparison. Therefore, the only assumption I see here is that some sort of grouping is possible or meaningful. Having made that assumption, the method is obvious. (Of course there are still questions of distance metric, merging method, and so on).

    Or have I overlooked something?

    That is done in biology (so-called numerical taxonomy) but phylogenetic trees are these days mostly constructed (or rather tested) using metrics based on parsimony and maximum likelihood. Say I have a homologous gene sequence from a number of different individuals, and I propose various family trees that might connect them all, which is the smallest number of changes needed to build a tree?

    There's lots of software around to do this, none of which can give a definitive answer because of the combinatorial explosion involved in comparing trees. I've got links to some of it on this web page Which I have just realised has some bad html in it. Duh!

    And I have also just realised doesn't have links to the two most useful sites for this, PHYLIP and PAUP Even if you never need to run the programs the websites are a good introduction to how phylogeny is actually done. The nice people at Washinton state also have a great page of links to phylogenetic software.

    Doesn't have to be, there are other methods.

    Where else did all those statistical techniques come from? Cluster analysis was invented by and for biologists! (apparently the term was first used by RC Tryon who was, I think, a rat geneticist (I am not sure what his relationship was with the R Tryon who published on fern taxonomy in 1899 and in 1962 and in 1990... I know taxonomists are long-lied but htat's getting ridiculous!) In fact most of the commonly used statistical techniques were invented by or for biologists. Mostly in the next street to where I'm sitting now. The name of RA Fisher springs to mind, perhaps the second greatest genius of British biology, and the man who foisted Analysis of Variance on the world. Or Kendall who worked for the Ministry of Agriculture. And there were Sokal and Sneath, taxonomists both. And the rather dodgy set of methods that were developed by followers of the ecologist Braun-Blanquet. Or Galton and Pearson and Weldon, the original biometricians (and inventors of chi-squared tests and . Spearman (correlation coefficients) was a psychologist to start with. Gosset (originator of Student's T-test) was the microbiologist for the Guinness bewery.


    Of course the biologists didn't invent statistics (philosophers and astonomers mainly did that) somuch as package them. This explains the difference between biologists and economists. Biologists are scientists who know they are crap at maths so they have had to invent all these packaged statistical techniques to help them wing it. Economists are not scientists, and they do not realise they are crap at maths, so they copied the stats from the biologists without understanding them. and they think they are scientists because scientists use mathematics.

    Ah! That is the important piece of information I was missing, having come initially from a computational physics background. (Physicists can be a bit insular).

    Without this piece of information, lots of interesting questions are raised about why a particularly common method for grouping data just happens to be such a good model for phylogenetics.

    There may even be some evolutionary advantage to this behaviour, as it quite often works to our advantage. One of the things we do very well is create mental models (of lesser or greater accuracy) about what's actually going on out there. When we use a model, we're saying "I know what's going on here, I don't need to re-examine it in every detail, I can assume it works thus and so I can quickly decide what to do".

    Lots of times that's a good thing, and if a model seems to works particularly well for you you'll be naturally resistant to reassessing it just because something at odds to it swims into your ken. Lots of times it's not such a good thing, but if you've fully retreated into the model to the extent that you've pinned your life on it then it's no surprise if you equate all potential upsets as potenially life-threatening.

    If Dembski decided evolution was right, for example, he'd lose an immense amount of status, money and self-definition. The same isn't necessarily true in the other direction, of course; moving from the minority to the majority gets you at best a momentary flash of fame as your wings burn off, but moving the other way makes you a big time hero to the few regardless of the details. Anthony Flew's probably the best recent example.

    According to the Grauniad, 30% of university students are creationists. I'm not sure exactly what this means, though - the three options mentioned in the article are creationism, intelligent design and evolution, and the wording of the survey isn't mentioned. I suspect that a lot of moderate viewpoints could be shepherded into the two categories the Grauniad seem to want to identify as Fundieville if the question was asked in the right way.

    I think the last few paras give the game away that this is a typical bit of fundie-bashing, disguised as a serious news story. But does it have any meaning beyond the probably misleading headline figures?

    It's almost impossible to figure out what, if anything, such surveys mean without the actual questions asked. And, I can't find anything on the website of the polling organisation mentioned about this work. Somewhere on this thread I think there's some discussion about something similar last year, which basically boiled down to very poorly phrased questions (ie: the "Evolution" option really only allowed the convinced athiestic materialist to answer because they defined "evolution" as meaning there's no role for a supernatural creator).

    Oh yes, I remember reading that. Interestingly, there's a hint that the same rather bizarre definitions are being used in the mention of 10,000 years for creationism, both in that survey and the Grauniad article. I wish I could get at the actual survey questions, but it looks like this is either the same survey or a very similar one.
     
    Posted by Alan Cresswell (# 31) on :
     
    OK, the polling organisation has put the results of their survey online, pdf file here. The questions asked are on p5 (table 4), and have the same idiosyncratic definitions as the earlier MORI poll for the BBC
    quote:
    The 'evolution theory' - Humans developed over millions of years from less advanced forms of life. God had no part in this process.

    The 'creationism theory' - God created humans in their present form within the last 10,000 years.

    The 'intelligent design theory' - Some features of living things are best explained by the intervention of a supernatural being, e.g. God.


     
    Posted by The Great Gumby (# 10989) on :
     
    Thanks Alan. I tried looking for that, but couldn't find it anywhere. So, in conjunction with the BBC MORI poll, we can conclude that university students aren't dramatically different from the population at large, but possibly slightly more likely to have an absolute materialist worldview.

    And they call this news? [Roll Eyes]
     
    Posted by Divine Outlaw Dwarf (# 2252) on :
     
    Why do you think 'absolute materialism' is implicit in these findings? That God is not a 'part' of any 'process' is implied by classical theism. If this belief is indicative of absolute materialism then Augustine and Aquinas were absolute materialists!
     
    Posted by The Great Gumby (# 10989) on :
     
    Well, doing my best to consider what I'd answer if I believed x, I can only imagine giving the evolutionary answer if I were an atheist materialist. I read the bit about God not being involved as saying that He wasn't involved even in creating us at some point. I don't know if that meaning was intended, which is one of many reasons why it's a badly-designed survey, but the general implication of this option, compared to the others, seems to me to be a somewhat atheistic worldview. I might have that wrong, though.
     
    Posted by Karl: Liberal Backslider (# 76) on :
     
    The option is indeed badly worded. Actually, I would have gone for that option, but that's because I would be putting some provisos in - starting the statement "From a purely scientific frame of reference" for starters.

    What I mean is that I do not believe that one has to invoke God as a mechanism without which evolution will not work, any more than one has to invoke Him as a mechanism for how paint dries or how aircraft fly. God's position as Creator transcends the scientific explanations; He is behind all of them; creationism and it's malformed offspring ID propose however that God is Himself a mechanism, scientifically describable. The problem here is that it actually reduces God's sphere as Creator. If we say, as Behe might, that God specially created the blood clotting cascade, but evolution naturally took legs off of whales, we make God more the creator of blood clotting than He is the creator of whales. Rather a theological problem, in fact.

    From a theological frame of reference, of course, God is intimately involved with the whole process, which leads me on to the fundamental error of all forms of creationism, which is that of a form of category error. Creationists try to describe God's creative activity within scientific categories, as competing explanations to natural ones. In creationism, either God created something or a natural process did. This guarantees God a gradually decreasing role. Creationists see that, I think, which is why they try so hard to refute scientific discoveries.

Unfortunately, in this case, there may actually be a swing towards ID in the Catholic Church - even if the Pope himself is probably too canny to actually commit to one opinion or another.

    I don't know. The reportage on this one is all over the place - Father Coyne is 72 and apparently undergoing chemotherapy for colon cancer, so could reasonably be expected to be laying down his telescope - but given some of the RC dogma on contraception I don't have much hope of sanity breaking out.

    On the other hand there's nothing illogical about being a Christian, a creationist and a believer that God is behind everything, providing you don't claim that it's scientifically verifiable. Il Papa could issue a thundering bull to that effect, and everyone (except the Discovery Institute) would be happy.

    I wouldn't trust the Grauniad article as far as I could throw Alan Rusbridger. I suspect the Vatican's got the same problem as most of us - trying to affirm different answers to the "how" and "why" questions without giving a misleading impression. I'd have thought they'll be desperate to steer clear of alignment with ID, even if they want to support some of ID's conclusions. The slightest hint of ID in any papal statement will probably be reported as "Pope linked to US fundie nutjobs", or something like that.

    "Intelligent design" is a good label for my mind's fuzzy zone where faith and science meet. But I know it's fuzzy, and I know it doesn't belong in a science class. Maybe, maybe, sometime in the future there will be some hard math and physics to back up the idea with testable predictions of observable phenomena, but I ain't holding my breath.

    Well, the non-fuzzy definition of Intelligent Design is pretty much that. Some "hard maths" (in the opinion of the adherents of ID) has resulted in a concept they call "irreducible complexity" which (they claim) can only be explained by the action of an "Intelligent Designer" (which, we all know is the Christian God, but they don't say that because they want it taught in science lessons which won't happen if it has a religious label). The claim of the Intelligent Design advocates is that there are observable phenomena that prove "God did it".

    And such irreducible complexity has, of course, been tested and found to be mathematically inevitable (see the Dover PA trial) and can occur by evolutionary methods even in such things as circuits (the classic Thompson experiment which not only showed irreducible complexity, but showed a method achieved by evolution that beat the theoretical best method).

    I have big problems with the way that the term intelligent design gets used, for that reason. Scientists take precision of meaning pretty seriously. If a term means something specific in science it's best never to apply it fuzzily because scientists usually won't pick up on the fuzziness. They will almost always take the term to mean what they've been taught it means in science.

    I know a lot of Christians who claim to believe in "intelligent design" but when they are asked to define it they merely give me some version of the teleological argument. I don't know how many times I've heard "What's wrong with intelligent design? All it says is that things in the world are complicated so somebody/something must have made them. Why is that such a problem?" They usually refuse to accept that it can mean (and originally meant) something more specific, and they often have crap YEC literature, or crap articles from just about any media outlet (see, for example, the Guardian article a few posts up; it's easy to get the wrong impression from that), to demonstrate their point.

    Day in and day out my scientist friends make fun of my non-scientist friends who believe in "intelligent design" because intelligent design is a debunked scientific theory. If my non-scientist friends would instead say that they believe the teleological argument, which is really what they're trying to say, there would be some murmuring among my scientist friends (heck, three quarters of them would say "The tay-lee-o-what?"), and the more extreme ones would still go off about faith and science being completely unmixable. But I reckon there would be some cooling of the overwhelming attitude among scientists I know that science is under attack from those stupid fundamentalist Christians.

    :sigh:

    I'm not arguing that "Intelligent Design" is science. It's not even close at this point, if it ever will be. I repeat: "...it doesn't belong in a science class". I'm just saying the term resonates well for ME, personally and theologically, because while I believe that the mechanism of evolution works very well in explaining the world as we know it, I'm not a deist who believes theologically in the Great Clockmaker who set things running and left. Somehow in a way that is too big and too deep to be quantified (which is why it's theology not science) God is in the midst of creation which is ongoing.

    That's all.

    I realize the phrase "Intellegent Design" is too loaded with politics and lines drawn to be useful for me to apply to my own beliefs without a lot of explanation. And anyone's free to disagree with my fuzzy beliefs, anyway.

    So on what terms do you guys think about the intersection of God with the physical world- theologically?

    "God in the midst of ongoing creation" works pretty well for me.

    There are a couple of additional points I'd add.

    One is that Gods presence is subtle, and He's not going to show His hand by the bit of occasional tinkering in the machinery of life to prove Himself to some scientists (He may, and I believe occasionally does, "tinker with the machinery" out of love for His creation to put right something we screwed up - we call these events miracles, and as one-off events don't really lend themselves to scientific scrutiny in the laboratory).

    The second is that God created the machinery that orders the processes of this universe as well as sustains and upholds it all. "God did it" is a perfectly reasonable answer to questions like "why is the universe governed by regular patterns discernable to mere humans?" or "why is the universe here at all?" - ie: the sort of questions which science is spectacularly ill-equipped to address. "God did it" is a very poor answer to questions like "why does the blood clotting system work the way it does?".

    I've always had a problem thinking why an omniscient, omnipotent creator God would need or wish to interact with or intersect anything we are sensible of. What is it God does not know before it happens, and why does God need to change stuff as time reveals it?

    However, that's just me. A more interesting tack is that evolutionary theory posits random mutation followed by natural selection, and that since given a sufficiently potent deity there is no such thing as random the whole business falls naturally into the process of divine creation. Admittedly, it does look as if 'random' really is random at a quantum level, but why should we expect a subtle God to appear as anything else?

    These are matters of faith. At the 'taste and see' level, there is no sign of an active creator at work - and I would expect science to be able to detect same if there was objective evidence.

    In just the formal, church sacraments, MT, or in the sense that all creation is sacramental, imbued with the "energies" (have I got the right Orthodox term?) of God?
     
    Posted by Mousethief (# 953) on :
     
    The Orthodoxen have never limited the number of God's mysteries to 7. God is ever at work imparting grace to us through Her energies. I'm not sure I'd say "all creation is sacrament" though, as that seems equivalent to saying "none of creation is sacrament". To me, anyway.

    The problem with your argument is that there's nothing to reclaim for the phrase "Intelligent Design" because it was coined by Behe et al to specifically describe their hypothesis that certain features show specific irriducibly complex features that can only be explained by the direct action of an intelligent designer. "Design" has a much broader history of use within Christian theology, and a case may be made for reclaiming it as refering to something much broader than the specifically defined "Intelligent Design".

    Personally, the word I'd really like to reclaim from a very narrow understanding is "creation". I'd like to be able to say that I believe that "God created the heavens and the earth" without anyone assuming any particular mechanism or timescale for that creative act, nor anyone assuming any particular fingerprint left behind by the Creator.

    I agree that it would be nice to be able to use the word `creation' outside the context of YECism. However, I suspect for most people the idea that `creation' can encompass anything other than Special Creation is likely to be a tricky concept.

    As for the Creator's fingerprints: while I wouldn't expect to find any, I've never really understood the hostility among many Christians to the idea that we might do so.

    It's more a hostility to creationism in general, CC. Scientists loathe creationism because it basically turns round to them and says "what you have dedicated your working life to, and what you have studied, and what you know far more about than I can every hope to, is crap. I know best and you're Satan's dupe."

    I've been reading a book about Gosse, and he used the phrase "intelligent design" in the 1840s.

    Though he was using it in the normal sense of the word - not as a label for a particular theory.

    Yes, exactly! That's why its a good idea to always be sure to say or write "young earth creationism" to distinguish it from the mainstream of Christian thought. St. Augustine, Calvin, the original Fundamentalists and the Pope are all creationists but none of them are Young-Earth Creationists.

    Personally I'd like to popularise the word "Yeccie". Partly because it sounds silly, and partly because I think I may have coined it myself [Smile]

    Because the ID(TM) view implies that God made mistakes. Did shoddy work. I'd rather say that all creation bears God's fingerprint, though in different ways. In particular humans, made in the image (ikon, character) of God, and in God incarnat3e in Jesus Christ.

    And also because many scientists are fed up with being lied to or cheated or tricked. There really are YECs our there who will deliberatly misquote scientists, twisting their words to make it seem they believe things they don't. I have met people that has happened to, and they are mde very suspicious by it. And there are plenty of stories of people being invited to take part in a supposed debate, only to find they've been set up to be humiliated, a sort of sacrificial victim in a show trial.

    Coincidentally, there's a very interesting posting on The Panda's Thumb today from Nick Matzke, who was instrumental in discovering the precise way 'Intelligent Design' was invented as a synonym for creationism during the production of 'Of Pandas and People', the ID textbook at the heart of Kitzmiller. The whole post, linked above, is very much worth reading for anyone interested in the history of ID: it describes how Matzke painstakingly worked out how Pandas came about through multiple drafts and that the process contained vital clues about the ID movement's own genesis - in fact,it is an indisputable missing link that tied ID and creationism together beyond any form of doubt.

    quote:
    Although the Pandas drafts were obviously important in the Kitzmiller case, it is only slowly dawning on everyone just how significant they are. The drafts are nothing less than the smoking gun that proves exactly when and how “intelligent design” originated. This was probably the biggest discovery in creationism research since the finding that the Coso Artifact was actually a 1920s sparkplug (see RNCSE 2004 Mar/Apr; 24 [2]: 26-30). They prove that the cynical view of ID was exactly right: ID really is just creationism relabeled, and anyone who thought otherwise was either naively misinformed or engaging in wishful thinking.

    In my campaign to reclaim the words "creation" and "creationism", can I request a rephrase to "Intelligent Design was Special Creationism v2.0."?

    Though, that 2.0 doesn't really account for other versions of Special Creationism other than the YEC version - we also have "Gap Theory Creationism", "Day-Age Creationism", and "Progressive Creationism" at least.

    It's over two years since I posted on this board. It's interesting as I've changes my views slightly in that time. But then I like to think I'm always open to discussion and debate.

    Anyway I do agree with Alan that Creationism is a word that needs reclaiming. In a very good episode of the West Wing (the best TV show ever) presidential candidate Matthew Santos is asked if he believes in Intelligent Design. He replies "I believe in God and I'd like to think that he's intelligent"

    The existance and nature of the creator is far more important than How.

    I presume and I'm fairly confident about this that Alan, Kepler's Puppet and even Karl believe in a creator...

    AFZ

    P.S. I'm still relatively agnostic about this issue. The ID brigade have an absolute right to ask the question: What about this thing: can it be explained by a stepwise mechanism? Of course if they are intellecually honest then when someone explains such a mechanism they can't jump up and down and cry. Neo-darwinism as a theory depends absolutely on a stepwise mechanism. Of course Young-earth creationism depends on a particular Intepretation of Genesis.
     
    Posted by Rex Monday (# 2569) on :
     
    Creationism is one thing, creation science quite another. From a scientific point of view, all sorts of creationism are the same, from Last Thursdayism to the one where God hangs around tweaking each instance of radioactive decay or the one where he lit the blue touchpaper on the Big Bang and retired to a safe distance. I don't think you can be a Christian without believing God created everything, and thus a creationist.

    Creation science and ID say that science can demonstrate creation, but fail to show how - and those who doubt that should read the Kitzmiller court transcripts and Judge Jones' verdict. There really is nothing there; no experiments, no theory, no science of any kind.

    That to me seems a far harder thing to believe, and I have a particular problem with those who want to teach ID in schools alongside evolutionary biology. That's the sort of thing that makes creationism a dirty word.

    Alan, I'm a scientist with a substantial education, although there was no reason for you to know that as it isn't mentioned in my profile. I disagree with the majority position on the origins of the universe and this planet after having researched the matter in some depth over quite a long time. In my opinion there is no reason to suppose that the information recorded in the early chapters of Genesis is not factual.

    quote:
    The second gap is an apparent lack of reading in theology - maybe start with what Augustine wrote about Genesis, and Calvins commentary wouldn't hurt either.
    C'mon Alan, I was reading theology before you entered school. Your choice of possible corrective literature intrigues me though. As Augustine was the leading innovator in the introduction of the ludicrous 'original sin' idea, the major moving force in the adulteration of the Christian way with Greek philosophy, and the first writer I know who advocated war as a legitimate tool of a Christian society, I cannot accept that reading him again would improve my ability to grasp what Scripture says. Calvin, on the other hand, was a political murderer of the most horrifying kind and about as theologically useful as a doorknob with sharp edges.

    quote:
    From the theologians you'll see that there are ample reasons to prefer a non-literal reading of the opening chapters of Genesis. From the science text books you'll see lots of compelling evidence that the Earth is much older, and has a much richer history, than a literal reading of Genesis would allow.
    I find nothing in the theologians to support either discarding Genesis or squeezing it into any of the many proposed corsets that we are assured can improve its shape. In science text books I find only a bunch of parrots repeating ideas that don't stand up under scrutiny.

    Well, they were just examples. The sort of thing I was think of were things like these quotes from Augustine
    quote:
    It not infrequently happens that something about the earth, about the sky, about other elements of this world, about the motion and rotation or even the magnitude and distances of the stars, about definite eclipses of the sun and moon, about the passage of years and seasons, about the nature of animals, of fruits, of stones, and of other such things, may be known with the greatest certainty by reasoning or by experience, even by one who is not a Christian. It is too disgraceful and ruinous, though, and greatly to be avoided, that he [the non-Christian] should hear a Christian speaking so idiotically on these matters, and as if in accord with Christian writings, that he might say that he could scarcely keep from laughing when he saw how totally in error they are. In view of this and in keeping it in mind constantly while dealing with the book of Genesis, I have, insofar as I was able, explained in detail and set forth for consideration the meanings of obscure passages, taking care not to affirm rashly some one meaning to the prejudice of another and perhaps better explanation
    The Literal Interpretation of Genesis

    or
    quote:
    We see that our ordinary days have no evening but by the setting [of the sun] and no morning but by the rising of the sun, but the first three days of all were passed without sun, since it is reported to have been made on the fourth day. And first of all, indeed, light was made by the word of God, and God, we read, separated it from the darkness and called the light ‘day’ and the darkness ‘night’; but what kind of light that was, and by what periodic movement it made evening and morning, is beyond the reach of our senses; neither can we understand how it was and yet must unhesitatingly believe it
    The City of God

    I could have referenced several other early Church theologians; eg: Clement of Alexandria or Origen. I referenced Calvin to highlight the fact that such views were not exclusive to the Church Fathers, they were held by the Reformers (and, many others since then) too.

    A teacher from Liverpool is urging the DfES to incorporate creationist materials into science lessons. Reports here from BBC News and here from the Grauniad. The suggested creationist material is from the somewhat inaccurately-named Truth in Science, and they claim it is "useful for debating Darwinist theories".

    This looks like a fairly bog-standard creationist gambit - challenging a sacred cow, pointing out gaps in Darwinian theory, all the usual rhetoric. Of course, there's no attempt to explain why the challenge to the existing theory should take the form of creationist dogma, but I wouldn't expect anything else.

    Now, from a thermodynamic point of view, there is nothing that prevents things from becoming more complex, assuming that those things are in an energy-rich environment. But the theoretical advance in science that truly resonated with people was evolution. Suddenly, people really "got" the idea that complexity could arise naturally.

    This is not a blow to Christianity. But it is devastating for teleology.

    I'm no Creation Science advocate, but this argument loses me a bit. Isn't it the case that even though we know that complexity can arise, it is still an instrincially improbable event.

    I just want to respond to anteater from the Purgatory thread, because this expresses a common set of confusions. The first confusion involves the idea of "improbable." If we say that the equilibrium state of chemical species A and B in a given environment is such that 99% of the mixture will be the lower-energy A and 1% will be the higher-energy B, we might say that B is less "probable" than A. In that sense, yes, many hihger-energy compounds are less probable in a given environment than the lower-energy compounds. But, of course, both will be present in the mixture.

    The second sense of "improbable" is what the creationists want you to think when the first sense is appropriate, though. In that sense, a given compound that is more sophisticated -- for reasons that are simply assumed by the creation scientists -- would not arise at all under natural circumstances. There's actually been a fair amount of research into the chemistry of "primordial soups." This is an attempt to determine what arises from what starting environments. In general, this research is not done to "debunk God." Rather, the motivation is to better understand the chemical environment of early earth. The assumption is that we arose naturally, and the attempt is to "reverse engineer" our origins.

    It turns out that plausible initial conditions for our planet lead to basic building blocks of life. Given that these results are reproducible in the lab, it is hard to make the case that they are "improbable" in the sense that the creation scientists would like them to be. The research here is a long way from producing life in the lab. But it is certainly not the sort of thing that should lend comfort to those who would build their faith on the idea that the world was -- and could only be -- created in six days by a divine being.

    I've heard what I think is a version of this argument a few times from Christians who have trouble accepting evolution. It usually goes something like, "lifeforms/the universe are so complex and so finely tuned they can't be explained by an undirected process".

    My problem is, isn't this always what happens with probability when you start at the end point of a long, complicated process and work backwards? To me it's a bit like saying 'why did I make it rather than any of the other x-billion sperm?' It may be awe-unspiring to consider, but the improbability of me sitting here doesn't make the explanation of how I got here wrong.

    Well, I guess that if it were discovered that the world was designed by a physical force acting within the Universe - as a pet fish might discover an aquarium factory, if that makes any sense - then said Designer would indeed by a scientifically accepted entity rather than a religious one. The religion comes in when you start hoping that such an entity is acceptable to science whilst not accepting overwhelming scientific evidence against it.

    Arguments from design can be perfectly acceptable as scientific hypotheses - they just happen to be wrong.

    Of course, if such an entity were discovered, it couldn't possibly be the immanent Christian deity, and would go rather further towards disproving most of the world's religions than Darwin does. Which is a 'religious implication' I guess.

    If we manage to make artificial intelligence, and it grows exponentially, it would soon be able to create mini-AIs within itself. It could create virtual worlds within itself in which these mini-AIs could live out their little lives. The mini-AIs would have no way of knowing that their world existed only in the mind of super-AI. What's more, if super-AI told them the truth, they'd laugh, pointing to the age of rocks etc as evidence. (As if super-AI couldn't make rocks that looked old.)

    Super-AI could create a very large number of mini-AIs and a very large number of virtual worlds, all to a large degree of complexity.

    Since the Primary Universe would be an unlikely event, it's unlikely we exist in it. On the other hand, a secondary virtual world would be a highly probable event (given a super-AI). Therefore, we probably exist in one.

    Wouldn't it be ironic if the 6-dayers turned out to be right after all, and that all our grand empiricism has misled us. To create the world, God simply imagines it. When God stops 'running the program', the world ends. Forget about Big Crunches. The sky will roll back like a scroll. A really neat special effect.

    How would it be a deception? God told us he made the universe, not all that long ago. We simply don't believe him.

    God didn't say he made the world to look brand new, but he made it to look good. God may be more interested in aesthetics than in geology. How would I know?

    In the same way, we won't believe the end of the world has come because it won't be a red giant or a comet or whatever, but Christ returning on the clouds in glory with his holy angels. We'll look up and say "Impossible! Deception! etc."

    If the universe doesn't do tomorrow what it did yesterday, God must therefore be deceptive? No.

    God must smile. I hope he smiles. All us little people confidently declaring what he can and cannot do.

    He told us in the very stuff of the universe itself that He made it a very long time ago. To make a universe that is young but appears in every way to be old - as it does - is deceptive.

    If He's that uninterested in Geology, why make it look so consistently not only old, but the same age. I can take a lump of granite and subject it to umpteen tests. They will all, with a small error margin, give me the same age. That doesn't sound like God was uninterested in Geology; indeed, it makes it look like He was very careful to make it look old - if it wasn't, that's deception, just like taking a new piece of silver and "aging" it to pass it off as Queen Anne.

    In the same way, we won't believe the end of the world has come because it won't be a red giant or a comet or whatever, but Christ returning on the clouds in glory with his holy angels. We'll look up and say "Impossible! Deception! etc."
    How does that follow from what went before? It doesn't.

    Nope. Haven't pronounced on that either. So quit the dishonest strawman.

    Now that's an interesting point. Suppose for a moment that Jesus did turn water into wine. Would that have been deceptive? What would a wine expert have concluded on analysing that wine? He might have estimated its age, the type of grape used and so on, and he'd have been absolutely wrong in his analysis. But if Jesus freely admitted that he made the wine by miracle, and still the wine expert refused to believe, whose fault is that?

    "Ah," says the expert. "The very stuff of the wine tells me it's old etc."

    The mistake the expert makes is in thinking God can't make mature wine from water. Zap. In the same way, the cosmologist and the liberal theologian don't believe God can make a mature universe from nothing whatsoever. Zap.

    In terms of the super-AI referred to earlier, how hard would it be to change water into wine in one of its virtual worlds? Absolutely effortless.

    quote:

    We examine the present, we discern 'laws' and recurrent causal chains, and extrapolate into the past. Any break in that causal chain, you could call 'deceptive'. It's easier for all concerned for the past to unroll smoothly, with no miraculous discontinuities. But does it?

    In the same way, we extrapolate causal chains into the future, speaking confidently of the sun turning into a red giant in four billion years and so on. We'll be most irate when God breaks those causal chains also, and ends the world.

    Zap. No warning. Maybe tomorrow. All this will cease to exist.

    I've seen this one before. It doesn't wash. The thing is that wine appears aged because we know that normal processes take X amount of time to produce a particular blend of chemicals in the wine. However, with the universe, we have more than simple maturity. We have a history. We have a rock face which shows igneous intrusions, fossils of animals with evidence of diseases on them, fossil burrows - evidence of real events which, if the age is only apparent, never happened. An entire fictional history. Now, if Jesus had provided a certificate of provenance with the wine, put it into bottles marked Chateau Damascus, 300BC and miraculously covered the bottles with cobwebs, yep, that'd be deceptive.

    Wrong on two points. Firstly, the vast majority of theologians, liberal or conservative, are not young earthers - it's generally considered to be an extremist position. Secondly, we don't think He can't, we think He didn't. And since the Bible doesn't say "and God created the earth, but made it look like natural processes had done it over millions of years, even though they hadn't", I don't see any rational reason for doing so.

    quote:

    It's not about whether God could, or how hard it would be for Him. It's about whether He did. But some creationists seem to prefer to argue as if it's about what God could do, presumably because the straw man is easier to demolish than the real thing. This is dishonest. Don't do it.

    In that case, the faithful geologist, wishing to honour God, will continue to treat the rocks as very ancient, thereby studying what God thinks of as good.

    It makes no difference to science. Its the omphalos. God could have created the world five minutes ago. Tolstoy could have started writing War and Peace at chapter 6. But we live in the world. We have to play the cards we've been dealt. When we are doing science we worship God by seeing his good creation as it is.

    And it is very old. So God obviously thinks that very old is good.
     
    Posted by Karl: Liberal Backslider (# 76) on :
     
    Ken - you open up another reason why nurks young-but-made-to-look-old model is inadequate.

    God created the earth good. This is agreed with all parties.

    The earth is to all appearances, and all examination, old.

    Therefore, as you say Ken, God thinks that old is good. Or He'd have created a not-old earth.

    Given that God thinks an old earth is good, wouldn't it make sense for God to create it a long time ago?

    Otherwise we have a rather bizarre situation where God makes the earth, then realises He's made it too late, so has to fake it to make it look older than it really is.

    If God wants a world with dinosaur skeletons, igeous intrusions and fossil burrows in it (as He obviously does, because that's what we have), wouldn't the obvious course of action be to create a universe where the earth really had dinosaurs, igneous intrusions and burrowing animals in a time when what is later rock was mud? Which means it really is old.

    We don't know what is, only what seems to be.

    It's perfectly reasonable to say, "This 50 million year old rock was made yesterday." From God's point of view, it could have been made yesterday. From my POV inside the story, the rock seems 50 million years old, and that's what I must work with.

    Just as an author can create 'an old castle on an ancient hill' in the five minutes before breakfast, God can make an old universe.

    In exactly the same way, the universe seems to be such that it will run on for billions of years. That's what we have to work with and so we plant our tree, as Luther famously said. From God's POV, however, the universe will stop any time soon.

    An author can create such a castle, but it is fictional; its history never occurred. If it's meant to reflect reality; if the author is meant to be writing a history book, then he's a fraud. But that aside, you are creating a model where we can't know anything. Are you familiar with the idea of Last Tuesdayism?

    Last Tuesdayism says that the entire universe, including my brain and the memories it apparently contains, was created last Tuesday at 5pm by my cat, Suky. You say "Ah, it can't have been, because I remember going to church last Sunday!". But I say "When you were created last Tuesday the memory of going to Church was put in your brain by Suky. Do you doubt that Suky has the power to do this?". You can't prove that isn't the case. But doesn't it make existence futile, since never mind Last Tuesday; the universe might have been created a microsecond ago, complete and apparently having a past and a history. But wouldn't you think Suky to be somewhat deceptive, creating all these false memories?

    Ultimately, you cannot know that you are not the only sentient being in the universe, actually a disembodied mind floating through space misinterpreting random stimuli as the universe you think exists.

    Rather, we have to work on the provisional assumption that the universe is real, what we sense has objective reality, and if we see a supernova in a galaxy 100 million light years away, then there really was a star explode there 100 million years ago, and there really was a 100 million years ago for it to happen in.

    While I understand the point you are making, I think you give way too much in making it. When we see a car hurtling toward us, we do not "work on the provisional assumption" that we are in danger of being splattered all over the street. We have a real, unprovisional and unhypothetical appreciation of our danger.

    The Greeks used to play these mind games, and take them seriously. It was endearing, but idiotic. The plain fact is that our senses trump our reason when the two are at odds, except when we have overwhelming evidence that we have been misled. The game you acknowledge gets whatever power it has from the fact that we have all been misled on occasion by our senses. Of course, we have been misled far more frequently by our reason, but that's not what the game is about.

    To suggest that the world is other than it seems simply requires the person making the claim to provide a massive amount of evidence that this is the case. Saying, "If that weren't so, I would have to abandon my silly belief in scriptural literalism and actually think" does not count as such overwhelming evidence. This kind of nonsense deserves considerably less respect than your generous soul is allowing.

    Our wine expert is thorough. He isolates the yeasts from the wine and cultures them. The flavins tells him the type of grape. He determines the age by measuring C14 in the ethanol. He looks at the ratios of oxygen isotopes and determines the temperatures at which the vines grew. And so on. From all this, he paints a detailed history of the wine. When told it was actually made by miracle yesterday afternoon, he laughs.

    You get in the Tardis, whiz off, and meet a man called Adam in this garden. Adam's about 25. The garden's well established. Big trees. I do a quick bit of dendochronology. Some C14. Yep. At least 300 years old, these trees. This rock here (quick analysis in Tardis) is 50 million years old.

    Wrong. It was all made yesterday. Bloody deceptive, I complain.

    I don't see how God can work any 'physical' miracle without giving a misleading appearance of age and process.

    I think the OT creation stories are mythical, or at least extended 'parable', for want of a better term. Magic trees, flaming swords, giants in the land, towers reaching to heaven and so on. The text itself demands it, not science. Just so we're clear.

    My present point is that not even God can make some physical thing by miracle that has no 'misleading appearance' of age and formative process. I think this is true.

    An artificial intelligence would grow exponentially, given time and resources. It could then model a universe to any level of resolution. It could place mini-AIs into that universe. They would have no way of knowing (unless they were told) that their world was not the Primary Reality.

    Far from being a mind game that the silly Greeks played, this scenario is fast becoming a real possibility. If it's actually achieved, the probability that we ourselves exist in such a world would be almost a certainty. This is because there can be only one Primary Reality, but any number of virtual realities. Therefore, we'd probably be in one of them.

    Though virtual, it would also be as real as any empiricist could hope for. It's the principle of equivalence. If a virtual world is indistinguishable from a real world in every way, it is real. It ceases to be real the moment it becomes distinguishable. Every miracle tells me that this world is not quite real. When God ends the world, zap, we will suddenly realise the world was never real at all.

    In summary: Uber-AI can turn virtual worlds on and off at will, with all the appearance of age, with every rock and bug modelled to the finest resolution. For mini-AIs to accuse Uber-AI of duplicity would be just a little silly.

    The castle analogy fails because the characters in the book are not free. However, if Uber-AI writes a novel, he'll make a virtual old castle on a virtual ancient hill that are indistinguishable from the real things (and are therefore real), and his characters will be mini-AIs with real minds and real freedom. And yes, Uber-AI can do all this before breakfast.

    Yes, but laughing at the idea doesn't make it less true. The only way mini-AI can know he exists in a virtual world is for Uber-AI to tell him. Mini-AI will find it very hard to believe, and probably won't.

    Sure. Our virtual universe is real for as long as we cannot distinguish it from the real. We have to take things at face value and work from there. However, miracles suggest to me, at least, that it's not as real as we suppose.

    That's just not logical. Why can't there be plenty of (what you call) primary realities? Modern physics certainly has that as one of its plausible models. And "there can be any number" of x does not imply that y=x, unless you know more about other things that y could be, and the probabilities behind 'can'.

    I can't speak for the reality of your world, but the one I'm in lacks any indication that it's computationally generated. There are limits to computation, you know: it can't "just grow" like magic beans, no matter how clever the AI. The maximum amount of computation possible in our observed universe is finite (and at least to some extent known), and it's not enough to simulate the entire universe unless you define the entire universe as a computer with the single task of computing itself (and if that gets you tingling, have a google for the computational universe)

    If you're saying there's some huge computer outside doing all this, well perhaps. Occam says that it's not likely, and you'll have no more evidence for that than for any other Big Thing Outside Universe Makes Universe Go theory. Of which there are plenty already.

    I'm not sure this has much to do with the death of Darwinism, mind.

    If the cosmic froth idea is true, that would be the Primary Reality. There can only be one, absolutely rock-bottom reality, by definition.

    Besides, simulating a universe is not as hard as it seems. Uber-AI only has to model what each mini-AI is experiencing at any given moment.

    The logic is inescapable. If we can create AI, we ourselves are almost certainly (perhaps indirectly) the creation of the Uber-intelligence.

    None of that follows for a second. Computation doesn't just increase in power because of some divine fiat. Moore's "Law" just happens to apply at the moment (it didn't before the invention of the integrated circuit) because of a particular quirk in materials science at the moment. We'll be down to single-atom transistors soon enough, and we will _not_ have anywhere to go after that, at least not on the exponential. Thought can't change physics.

    And just because we can do something doesn't say anything about how things happened in the past.

    Not fair. You said there is limited computation in our universe, and therefore virtual universes are impossible.

Rather, if we make AI, it will be an argument for Primary Reality having massive computing power.

    Just because I rather liked my post, I'm going to move it here. I would be interested in seeing some response, if it doesn't duplicate something that has already been said about sixteen times!

    In relation to the idea that scientists can't accept the idea of a Creator:

    Despite my father having been a research physicist who knew an assortment of skeptics such as Bertrand Russell and Julian Huxley, I canot say that he ever denied that the Creation was an act of God. Similarly, I think you will find that many people studying the process of development after the Big Bang, or whatever start-up event there may have been, do not care to quantify what came before that point.

    Science deals with observable things and actions, and attempts to discern what patterns there may be, what rules may be theorised from those patterns, and what common threads there may be across the spectrum of observation. No reputable scientist would care to do more than theorise about that which he cannot observe in some manner.

    And a theory is not a fact. Hence, evolution is a theory that fits observable facts, so it is a useful theory.

    YEC does not fit enough observable facts to be credible, particularly because it denies the existence of some easily-observable facts.

    ID is an attempt to "fill in" what are seen as gaps in the reasoning, and to provide a theory for what occurred before the facts became facts. It is a theory. Because it argues from an unprovable base, it is suspect in "scientific" terms.

    But, just like cheering for "your" footie team works for you, even if the fact-base is arguable, ID can "work" for those who are unhappy with uncertainties between Scripture and science.

    But the clues we have here on Earth were put there by God as He built the place, so discarding some of those clues leaves you open to accusations of lack of faith, or, possibly, neo-atheism, ISTM.

    I would concur science provides 'hows' and theology 'whys'. The why will always be a faith statement.

    This is where Dawkins fails. He takes 'hows' and interpolates 'whys' yet denying the faith element to what he says.

    May I use an example of my existence.

    How do I exist. Through a process of evolution or Creation. But this doesn't answer why do I exist?
    The how is scientific in that it can describe the process of something.

    But the Why underpins the How and often it cannot be explained but merely taken on faith.

    i.e. I exist because God loves me and made me to be in relationship with him through [insert the how of your choice] or It is purely chance with no deeper meaning but part of a beautiful chaotic dance through [insert the how of your choice].

    I have no particular axe to grind for ID, but recently another poster brought up a question which seemed to me a good one in the days when I believed in it, and which I still don't see the answer to.

    If ID is unscientific, what about SETI? As I understand it, the idea is to scan space for radio transmissions, and when one is found with a certain degree of regularity, this is taken to be evidence of extraterrestrial intelligence and not chance.

    If a significant amount of information in a radio transmission is evidence of intelligence, then why isn't the large amount of information in DNA taken as evidence for intelligent design? Or to put the question the other way round: if random mutations are enough to explain the complexity of DNA, why can't chance similarly explain regular radio transmissions?

    That said, how far do scientists take the methodology of SETI seriously?

    This is the crux of the matter - these are very different sorts of randomness. Random mutations in organisms lead to varying evolutionary pressures - creatures with mutation A die horrible deaths, creatures with mutation B live long, prosper, go forth and multiply. Consequently, all their heirs and successors have mutation B. Although the mutations are random, their selection and propagation isn't.

    A random radio source on the other hand, has no history, no memory. Something like an unstable star doesn't repeat a pattern because it worked before - it just spews out any old radiation. If you want to know what that looks like, de-tune your TV or radio. A repeatable, complex pattern in an extraterrestrial / extrasolar radio source would be evidence of some form of control, so that the known pattern could be reproduced.

    But if the radio emissions are truly random, then you might get a repeatable, complex pattern. If I paid someone* to toss a million pound coins, they might all come up heads.

    The question is at what point does pure chance become less likely an explanation than intelligence when we've got no other evidence that such intelligence exists.

    Is the issue with Dembski's notion of CSI

    a.) that it's an inherently unscientific idea, i.e. that there's no point at which a stream of apparent information cannot arise by chance, or

    b.) that it's a sound idea in principle, but DNA coding is not sufficiently complicated to qualify, especially given that it is influenced by non-arbitrary factors such as natural selection and reproduction?

    You might, but you would expect, on average, to wait many times the age of the universe so far to observe even one such occurrence. (For example - a million people each flip a coin, every second. They will all come down the same (either all heads or all tails) on time in 2^999,999 - so you might expect to wait 2^999,998 seconds, on average, before one such instance occurred. There are approximately 2^25 seconds in a year. So you would be waiting 2^999,973 years. There have so far been somewhat less than 2^24 years, ever.

    The situation for complex radio emissions is even uglier.

    It's simple: DNA coding is not random. It's not the product of a random process. It's the product of extremely rigorous selection from a random sample. It's as though those million people toss coins, and I take the 100,000 first heads, and say "Look! A hundred thousand people threw heads!"

    Thanks. I hadn't thought of the age of the universe as being a limiting factor ...

    Nonetheless, surely DNA coding is a mixture of random and non-random factors? E.g. a certain coding XYZ might become dominant because it's better equipped for survival than its rivals, and so its propagation is not random - but the fact of its arising in the first place is due to random mutations.

    Another difference between SETI and ID is that the former provides a plausible scientific mechanism by which ET could be communicating through radio waves. Scientifically it is quite feasible - likely even - that ET lives somewhere out there, and it is also possible that it would evolve into complex intelligent life-forms that attempt to communicate with aliens. We know, because that's exactly what we have done.

    OTOH, I've never come across anywhere where the ID proponents explain precisely what the physical mechanism for their idea is. Do atoms just coalesce in some funny way under the control of little angels? Does God intervene to smite the individuals carrying gene-combinations that He doesn't favour? To be considered a scientific hypothesis, an idea must have some potential mechanism underlying it... and to my mind it is this that separates out SETI from ID.
     
    Posted by Callan (# 525) on :
     
    To be honest it's a false analogy. There are certain scientists who look for evidence of design all the time. Archeologists, for example or forensic scientists. Is that oddly shaped piece of flint an arrow head or just an oddly shaped piece of flint. Was that bump on the deceased's head caused by his falling down the stairs when drunk or was it administered by Colonel Mustard with a length of lead piping.

    SETI is much closer to the above examples than it is to trying to find gaps in the fossil record or arguing that the Bomardier beetle couldn't have evolved without God zipping in to ensure that the chemicals evolved safely. As dj_ordinaire points out we already know that there are sentient beings who use radios to communicate. SETI just attempts to establish whether any of them live on other planets. It doesn't have the same recourse to metaphysics as ID has.

    Given ID's studied hostility to methodological naturalism it seems slightly disingenuous to suggest an enterprise which can be carried on, on methodologically natural premises is some kind of analogy for an enterprise which maintains that methodological naturalism is a flawed method.

    The thing that gets me is that IDers have a two-pronged approach to seeing intelligence behind the universe.

    First, the universe runs on rules. Therefore, God.
    Second, those rules are sometimes broken. Therefore, God.

    It does beg the question, which has never been answered, as to what disproof would IDers accept?

    On the "Have we stopped evolving" thread in Purg, Mudfrug asked:
    quote:
    Is there anyone able to give evidence to show one species evolving into another, rather than one species adapting and showing variants within itself?
    OK, I'll bite.

    Have a look at this page.

    What this page shows is a grouping of protein sequences by similarity for a protein called 'Cytochrome C' (more info here.

    The proteins are labelled on the right with the latin species name, with the species arranged in an "evolutionary tree". If you click the boxes on the right for some species, you can compare the protein sequences.

    Try for example selecting Homo Sapiens, Pan Troglodytes, and Sus scrofa (human, chimp and pig), and go back to the top of the page and click the button there. You'll see a comparison between the protein sequences - the sequences are too long to fit across the screen so it is broken into groups. Note that Human and Chimp CytC are identical, wheras pig has 4 differences.

    If you try other species, you'll find that the number of differences increases as you get creatures which are more different.

    Now, that on its own doesn't prove the point. The proteins could be the same because the they are tied up with the shape of the creature, and humans and chimps are more similar in shape than humans and pigs. Which is a valid hypothesis, but falls down if you test it. Humans can manage just as well with pig cytochrome as with human or chimp cytochrome. In this case the similarities demand some other explanation.

    So we have an inexplicable similarity between proteins from humans and chimps, which cannot be explained by a biological imperative. The obvious interpretation must surely be that there must be some other connection between Humans and Chimps (and between mice and guinea pigs, and so on).

    Now that's just one protein. There are thousands here.
    And for many of those, sequences are available across hundreds of species. And in every case, you see a similar pattern: species which are considered under evolution to have a more recent common ancestor have proteins which are more similar than those which are more different. Gigabytes of data, all telling the same story.

    You can even draw a tree or a map based on sequence similarity. I did this using ~30 cytochrome sequences dowloaded from the public databases and a computer program I wrote myself in an hour, and got something looking very much like an evolutionary tree. The same sort of tree which was devised by biologists a century ago who had no idea what a protein sequence was. You can do this youself - you don't even need a computer - the tree can be calculated with a pencil and paper in a few hours. It seems to me as though we can legitimately say that there is something which looks like an evolutionary tree written in the very symbols of the molecules of life.

    To summarise, all these species have related proteins, and in many cases the similarity is greater than can be explained by any requirements of the function of the protein. The "plain reading" of this result is that there is some other connection between the species. If we group the species by their species similarity, we just happen to reproduce the same type of relationships which were postulated by evolutionary biologists before the availablity of protein sequence information.

    Yes. But I am still left with the observation that the theory of evolution is written into our genetic codes.

    If evolution did not happen, and the information was put there by the Flying Spaghetti Monster, then I am faced with some rather big questions about why the FSM chose to write such an unambiguous but misleading message.

But I felt I ought to flag up that many people on the other side of the debate are not troubled by such considerations, and that therefore the elegant demonstration may fall on deaf ears.

    The evidence for the actual course of evolution is no more specially from fossils than from living creatures - less so because living creatures have more charactes we can study. As just explained the main evidence for the course of evolution comes from nested realtionships between gene sequences.

    Its actual kinship we are talking about. Common descent. And the way to explore that is to look at shared characters - especially shared genetic characters - between living creatures as much as fossils. There's nothing special about fossils just because they are dead.

    More to the point, they show comment descent i.e. that ancestral forms have evolved into the current diversity of life... but they don't show how this occurred. Unless you can relate changes in primary sequence to evolutionary pressures, then this doesn't by itself prove that natural selection is responsible for the observed evolution.

    OTOH, there was a report in Nature, late last year IIRC, which demonstrated the evolution of a new species of butterfly following the emergence of a particular selective pressure. That would provide the sort of evidence being sought. I'll see if I can dig it out.

    True. However proving common descent of different species at least proves that speciation is possible, which is major step in the right direction, and a common objection to evolution.

    Do you mean this story?

    My understanding is that this interesting feature of the butterflies is that they demonstrate what had previously been a hypothetical mechanism of speciation without geographical isolation. My interpretation of the article was that speciation by geographical isolation was already well supported, although since that is a tangent to the topic of the paper it doesn't receive any detailed attention in the article.

    Only if they say "what use is half an eye"; and quote the first half of Darwin's comment on the subject of eye evolution:

    "To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree. (Darwin 1872)"

    without carrying on the quote where he says:

    "Yet reason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist; if further, the eye does vary ever so slightly, and the variations be inherited, which is certainly the case; and if any variation or modification in the organ be ever useful to an animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, can hardly be considered real. How a nerve comes to be sensitive to light, hardly concerns us more than how life itself first originated; but I may remark that several facts make me suspect that any sensitive nerve may be rendered sensitive to light, and likewise to those coarser vibrations of the air which produce sound.

    I just finished reading Monkey Girl, which is the story of the Dover, Kansas trial re: ID in the classroom (referenced upthread a couple of years back). Now I'm feeling an overwhelming urge to talk origins.

    It's a good, detailed story of the trial. I can't quite recommend it to my conservative friends and relatives, because they might perceive Humes as against Christianity. (He's clearly not an ardent fan, and that can be enough to paint him as an enemy.) I enjoyed it, though.

    I originally responded "name three", but I thought I'd save FCftS the bother by raising three of the usual creationist accusations of hoax.

    1. Haeckel's embryo pictures.

    Yes, Haeckel did distort some of the features of his drawings. However, contra the claims of some creationists, Haeckel was not actually trying to use his diagrams to support evolution per se - he was doing so to support his particular pet theory - long discredited - that ontology recapitulates physiology - that a creature, during its embryonic development, relives its evolutionary history. It doesn't. It remains true that embryos show considerable similarities in development, and that similarity is strongest early in development, and that embryos do develop some features which were present in its ancestors but absent in the species now - such as tails in humans, but Haeckel's distortions were a hundred years ago in support of a long discredited hypothesis.

    2. Piltdown Man

    This was a hoax perpetrated upon evolutionary biologists, not by them. In fact, by the time it had been shown to be a fake, it had become a problem, because it didn't fit in with the other human fossils. It was rather a relief to find it was a fake, and this had been suspected by many scientists simply because it didn't fit in with other discoveries.

    3. Nebraska Man

    Allegedly (according to creationist myth) this is a humanoid reconstructed from a single tooth which turned out to be a pigs tooth but which is still in text books. Here the creationist version is wrong on several points.

    (a) It's not a hoax but a mistake
    (b) The mistake was noticed within a couple of years. "Nebraska Man" never got properly integrated into human evolution, because there was such a short time between the discovery and the correction about the origin of the tooth.
    (c) He's not in any textbooks, apart from creationist ones.

    Any more, FCftS?

    1. So Biogenetic Law has nothing to do with evolution then? Right. Despite those drawings surving in textbooks still, and still being used, like they were always used, to support evolution. The fact that Haeckel may not have meant them to be used in this manner means nothing.


    There is no fossil record that I know of that demonstrates a clear evolutionary transition. The only ones that have ever claimed to have done so have been forgeries. Like Archaeoraptor liaoningensis. Add that one to the list. As Darwin himself noted, most transitional forms are so close to the original species they are trying to link that they have no value one way or the other.


    2. I agree with what you say about Piltdown Man.


    3. No problems with Nebraska Man. Although are you saying that this 'mistake' had albsolutely nothing to do with evolutionist belief? Come on.

    If by "Biogenetic Law" you mean ontology recapitulating phylogeny, then it's been discredited for decades. If you mean what I said, about embryos being more similar early in development, then it's evidence for evolution, yes. But this is the important bit - photographs and unaltered drawings show this just as well as Haeckel's questionable drawings do - so Haeckel's misdemeanours really don't make much odds.

    If you can find me a modern textbook using Haeckel's drawings I'd be surprised - there may be one or two around. But the same phenomena are clear, as I said before, in other drawings and even in photographs.

    That was a fraud perpetrated on evolutionary biologists by a Chinese farmer, not by them. You are confusing perpetrator and victim here. It was a shame that National Geographic jumped the gun and played the Easy Mark for the fraudster, but they didn't actually set out to fool anyone.

    quote:

    Apart, of course, from the footprints. But what do you mean "has been given"? Artist's reconstructions of course give her our best deductions, but the scientific description of the find, in the actual literature, does not describe anything which is not there. You are aware that Lucy is not the only Australopithecus skeleton we have, aren't you?

    Well, of the thirty-two animal phyla, eleven appear in the Cambrian, one is pre-Cambrian, eight post-Cambrian and twelve have no fossil record (Collins, 1994). There are no fish anything like today's, no insects, higher plants, spiders, crabs, lobsters... It's a very different world, as evolutionary theory would expect. In what way were "complex invertebrates" not "due"? They don't have a schedule; they evolved when they evolved.

    What you would find in a geology textbook is the difference between layers of ash and pumice and the sorts of sedimentary rocks that occur in other environments. I am aware that the ICR tries to suggest that they look the same, but no geologist would think so.

    I've read more books about evolution than you can shake a stick at, and I've *never* seen the Haeckel drawings in any context other than the one Karl described: discussing a discredited theory about the development of embryos. I've certainly never seen anything like "evolution happens - look at these drawings!"

    Check these babies out:

    Yeah but you know, we've found a hell of a lot of fossils since Darwin's time. And gained a tremendous amount of knowledge about dating. This just isn't a problem anymore.

    Evolution is not a "belief". It's backed up by vast quantities of evidence. One mistake does not discredit the entire theory any more than one ballsed-up experiment in a chemistry lab proves that the periodic table of the elements is completely wrong.

    When you're trying to reconstruct what an extinct species looked like, you sometimes have to make educated guesses. It would be more misleading to pretend that we knew she didn't have hands, than to make the perfectly reasonable guess that, since Lucy is a primate and primates generally have hands, Lucy had hands.

    quote:
    9. CroMagnon man is at least equal in physique and brainpower to modern man, SO, whats the difference again?
    Cro-Magnon man was Homo sapiens, the same species as us. So in terms of species, no difference. He's called Cro-Magnon man after the place where his remains were found, like "these are Roman remains", not because he's a different species.

    No problem. Invertebrates aren't a phylum. They are part of a phylum called "Chordata". Many chordata species *are* invertebrates, but not all. Walcott's fossil hunting ground, the Burgess Shale, did include some chordates, most notably Pikaia.

    My beef with YECs is the way that they keep presenting these "unsolved problems with evolution" which have in fact been solved time and time again. But I'm sure you can find fakery in creationist materials if you look.

    Did you mean to say that Vertebrates are part of Chordata? What's interesting is that there were chordates in the Burgess Shales, but no vertebrates - exactly as evolutionary theory would expect. Since Chordata includes such animals as sea squirts, it's not exactly as if ostriches, mice and T. rexes are sitting there in the Cambrian.

    This mostly written about 3 hours ago but I had to go and do some actual work before posting it. So probably massively cross-posted. If it agrees with what others may have said in the meantime it shows we've got our story straight [Biased]

    quote:
    Originally posted by fight-club for the soul:
    1. So Biogenetic Law has nothing to do with evolution then?

    I've not heard it called that for a long time, if ever.

    And of course its about evolution. The idea is based on the notion that it is easier for an organism to add extra bits on to the end of a chain of development inherited from its parents than it is to alter earlier stages in development. If this was universally true than comparing embryos would allow us to reconstruct kinship. As it is not universally true however, it doesn't - at least it doesn't unless allied with other data.

    The theoretical biology of patterns and forms was all the rage in the late 19th and early 20th century and has been out of fashion for the last sixty years or so. Not so much because it was discredited as because genetics and molecular biology turned out to be more productive of new ideas so the sort of mathematically and artistically-minded biologists who might be good at it have tended to do their research in other fields. Some of the classics of the field such as D'Arcy Wentworth Thompson's On Growth and Form are still popular and its the sort of thing that eminent professors turn to in their semi-retirement.

    Also comparative embryology is downplayed these days. Probably mainly because it is very hard, and involves looking down microscopes for thirty years then emerging into the light of day with some crazy theory that no-one else can even understand never mind agree with. Though the fly people got a Nobel in the 1990s and everyone has heard of Dolly the Sheep so things are very slowly looking up for embryologists. Its more common among botanists than zoologists for obvious reasons.

    quote:

    Right. Despite those drawings surviving in textbooks still, and still being used, like they were always used, to support evolution.

    Name one serious textbook of the last thirty years that does this. NB many of them show such pictures as examples of historical ideas, because it is common to teach this subject historically - you lecture about Cuvier and Lamarck before you lecture about Darwin, then you move on to the Mendelians and the Neo-Darwinians & so on - but that is not the same thing.

    When I was at school in the 1960s and 1970s it was already a cliche to say that people used to believe that ontogeny recapitulates phylogeny (did Karl use a speeilecheeiker?) but now we know that it doesn't. Which is a cliche too far - if obviously does, sort of, more or less, most of the time (especially among plants), but not regularly enough to be predictive. Earlier events of embryology are themselves subject to evolution and whole stages and subsystems can be deleted. So though its great fun its not much use in taxonomy - or nowhere near as much uses as molecular data anyway. There are, it now turns out, loads of different ways in which changes in the relative speed of development of different parts ("Heterochrony") can affect the form of adults. They were pretty extensively catalogued by Stephen Jay Gould in his book Ontogeny and Phylogeny (one of his genuine theoretical contributions)

    Also I think you are confusing arguments about the course of evolution with arguments about the fact of evolution - not the same thing at all. (And embryology certainly does support the idea of kinship among living things which is half of what you need to believe in Darwinian-style evolution)

    quote:

    What's that got to do with the price of fish?

    8. Lucy the ape (Australopithecus Afarensis), who has been given human hands and feet despite no evidence to support this.

    Again arguments about the actual course of evolution of our nearest relatives, which is all very well but is NOTHING to do with the disputes between scientists and YECcies. If it were to be shown tomorrow that every single supposed human fossil we have was a fake there would be no reason for anyone in the world to change their opinion on evolution either way.

    This is Natural History, not Natural Philosophy. One counter example does not disprove a theory. We're not doing maths. The Hitler Diaries are fakes. That in no way invalidates the study of history, nor does it mean that we can't say anything about the modern history of Germany - it just means that those documents aren't useful evidence.

    I tend to get all those human fossils mixed up anyway. Human palaeontology is dominated by notorious splitters. And not a few publicity junkies. And some of them still give the impression that they believe that we can find fossil ancestors. I don't think they actually believe that - I doubt if any working palaeontologist does - but they give the impression they do, which looks a little disingenuous to me. You get more TV time saying "this fossil is one of our ancestors" (which no serious palaeontologist believes about such things) than you do saying "this fossil is of a member of a species that is almost certainly and in many ways very much like the common ancestors of modern humans and some other species you guys haven't heard of ether" (which is usually what they mean)

    I don't see the problem. If correctly identified (there is still a lot of controversy about that) they mean we were wrong about the date of divergence by about 7% which is not that far off on this scale. Which is all tremendously interesting.

    Personally I think the phylogenetic divergence of the major phyla happened quite a but earlier but either the separate lineages still resembled each other closely or else they didn't fossilise - that's very common phenomenon - for example the molecular data separated the four or five main groups of mammals from each other some time before the Cretaceous and the main families within them during the Cretaceous. But the first distinctive fossils don't appear till much later, in the Eocene or Oligocene or even more recently. That might well be because all those different lineages of early mammals just looked like early mammals. It is as if four of the current species of mice survived for tens of millions of years and diverged. Their fossils being liad down now woudl still look like mice. The separation of lineages happens before anatomical divergence.

    There is also the related phenomenon of "lawn phylogeny" which is when a rapid adaptive radiation produces many similar lineages all at once - relationships between them are hard to resolve.

    There are also some technical problems in using molecular data to resolve deep trees which would be a bit longwinded to go into.

    But not sedimentary rock. Keep up at the back!

    That kind of formation is actually quite familiar in palaeontology because it is one of the things that can cause large-scale preservation of high-quality fossils. As long as the ash isn't too hot!

    Simon Conway Morris is an interesting character. He seems to regard the evolution of humans (or human-like creatures) as inevitable, which is very interesting. Generally I'm sure he knows a lot about paleontology but I definitely disagree with him on this one. I remember being utterly aghast when I saw him on the programme about what the world might be like had dinosaurs not become extinct, and he was suggesting that by now they might be a bit like green scaly humans. That viewpoint makes my brain hurt. Has anyone read this book?

    I spent years debating with creationists, and not once did they present a single piece of scientific evidence that held water any length of time. The best efforts were the ones so hidden in mathematical formulae that you had to be a mathemtician to know what they were trying to claim, never mind why it was wrong (Humphreys' Starlight and Time thing, for example).

    So if such evidence does exist, it's not widely known. You'd think it would be, wouldn't you? If it were, why would the creationist machine keep creaking out the same old kack that it does?

    SCM was also referenced in a book I read not long back called Singularities by Christian de Duve, a Nobel prize-winner and cell biologist (yay!).

    He liked the first part of the book which emphasised the importance of convergence for ensuring that the Earth was likely to produce something very like us sooner or later, even if the lineages in the Burgess shale had undergone very different fates from the ones they did... and disliked that the later parts about how most other planets couldn't evolve anything at all. Self-contradictory, he thought it, and I rather agree.

    "... with theological implications which [Conway Morris] does not hesitate to emphasise" I think the phrase was.

    Going back to whoever raised Haeckel, there's a (possibly more than coincidental) recent mention of him by the Disco Institute, which in turn provoked a response by the doughty PZ on Pharyngula. That link includes quite a lengthy analysis of what's left of Haeckel's diagrams in modern textbooks - and how they're misinterpreted (and that's the very kindest way of putting it) by the IDers.

    And while thinking of the various hominid lines and the fossil evidence for them -- it's always fun to ask creationists which of them (the hominids, not the creationists) are men, and which not. I don't believe there's ever been an answer to that.

    I recall some discussion about clays being nucleation surfaces for cell-like structures that could be the precursers of life a few years back. It may even have been around 2003, the date on that article. I'm pretty sure Mike Russell gave a talk or two about while he was working with us, though his preference is for hydrothermal vents.

    The consensus is that life definitely appeared in water. But the open oceans just disperse pre-biotic material too quickly, there needs to be something to contain reacting chemicals in. The pores between clay particles are a very good candidate site - especially if they allow proto-cells to form.

    There's a good discussion about many of these ideas here , which is quite blunt in its conclusion - we just don't know. It also shows that as we think about the issue, more and more intriguing possibilities suggest themselves. It's like looking at Mars: the more we investigate, the stranger, more complex and more exciting it gets.

    Posted by Alan Cresswell (# 31) on :
     
    As with practically all such discoveries, it can't be shown to be a "missing link". There's no way we can prove any given species in the fossil record is the direct descendant of any living species.

    What the discovery does show is that there was a much larger range of variation within feathered dinosaurs than previously thought. I don't think anyone was expecting any to be that size. The other thing it shows is that feathers were serving a purpose other than flight - there's no way that beastie was going to take to the air. Which closes a "gap" in the story of avian evolution - that is that as birds evolved they took a structure from their ancestors (feathers) and put it to a new purpose. Which I don't think any serious paleantologist has doubtedly for a long time, though there may have once been a school of thought that saw dinosaurs start to fly without feathers (somewhat akin to pterosaurs) and develop them as they aided flight.

    I'm not sure the Bible says that. In the first account humanity is created the same way as everything else; the difference is the Imago Dei. In the second creation account, man is made from dust and then all the animals are made - also "out of the ground" (2:19). I don't see, therefore, that there's a distinction of one being made from dust and the others ex nihilo - in the first account it could all be ex nihilo; in the the second it's all out of the ground.

    Neither creation accounts in Genesis specify creation ex nihilo, that's an idea that comes from Hebrews mainly. The best you can manage, and seems to work well, is that "In the beginning God created the heavens and the earth" being ex nihilo. But, from that initial creation we then have an earth that's "formless and void" with creation from that point largely (and probably totally) proceeding with a re-arrangement of the material of the earth; in some cases that's explicit such as when the waters are re-arranged to give dry land and seas.

    "The Sunday Herald has learned that the Scottish Qualifications Authority (SQA) is considering provision for the theory as part of a review of the science course curriculum.

    Intelligent design (ID) is one of a wide range of theories of origin currently taught as part of the Religious, Moral and Philosophy Studies (RMPS) SQA course, but could be moved elsewhere as part of the review. A spokesman for the SQA said: "It happens to sit in RMPS just now. If and when it does becomes part of the curriculum for science, which it may well do as part of this review, then that's where it could sit.""

    Hey folks. I'd like to try and find some good up-to-date books on understanding how Genesis and evolutionary science relate, in particular from an evangelical point of view, out of my own interest and also because I want to find some stuff to recommend to a friend who's studying Biosciences at university who I've been chatting with about this kind of thing.

    I've had a quick look through some of the pages on this thread, and couldn't spot recommended reading of this sort, so I wonder what people would suggest?

    I haven't read Reason, Science and Faith for some time, but remember it as well written and argued when I did read it (over 20 years ago now). IIRC it predates the Intelligent Design issue and so is definitely dated. But worth a read.

    I'd also second the Science, Religion and Faith recommendation. Though it doesn't include ID it is still gives a good back ground on the larger discussion re: YEC and other forms of creationism. A good combination of theology and history of science that would put things into a decent perspective from which the newer ideas of ID can be addressed. Forster and Marston used to maintain a site here containing the text of the book and some space for discussion - unfortunately it appears to have been hi-jacked by Answers in Genesis and just contains their (somewhat biased) review of the book [Mad]

    I'd also add Science, Life and Christian Belief by Jeeves and Berry to the list. An extensive discussion of the history of Judeo-Christian thought in the development of science. There's an extensive section on evolution and biological science. But, a lot on other aspects of the intersection of the Christian faith and science (eg: psychology). I notice the Amazon site lists a 1999 edition, which I think is newer than the copy on my shelf at home (I'd actually need to be at home to check that) and may have a bit more stuff in it.

    Its not "somewhat biased". It is a hateful pack of lies. How can people who claim to be Christin ministers deliberatly pose as honest men when they are willing to lie about God, science, and the Bible in order to defame other Chritsian ministers? As if any further proof was needed that YEC is fundamentally an anti-Christian movement.

    This is interesting...
    quote:
    From the article:
    Creationism, by any name, adds nothing of intellectual value to the effort.

    Well, I think I've nailed this article's ultimate concern.

    How do you determine "intellectual value"? Since the intellect is itself an abstraction piled upon abstractions, how do you measure it?

    I think the article does a fine job of ripping up simple creationism (not that that's really very hard to do, since all the opposition does is "pursue argument by exclusion--that is, they belittle evolutionary explanations as far-fetched or incomplete and then imply that only design-based alternatives remain," but I find the ultimate argument for the value of the underlying approach interesting.

    Is every theological attempt to work with scientific-derived understanding really "intellectually bankrupt"?

    I also found these two sentences kind of interesting if you place them next to each other:
    quote:
    Some people introduce new particles, such as quarks, to flesh out their theories only when data show that the previous descriptions cannot adequately explain observed phenomena.
    quote:
    intelligent-design theorists invoke shadowy entities that conveniently have whatever unconstrained abilities are needed to solve the mystery at hand.
    They're kind of wordy, but they both sound like "people introduce new ideas when their old ideas stop working."

    The only difference is that creationist models are open-ended (God can do anything) while scientific models try to constrain their ideas as much as possible (we're only using this model to explain a particular phenomenon, therefore it probably only has influence in that particular phenomenon).

    I'll admit that my vaguely theist (perhaps post-theist?) leanings may be biasing my reading, but the difference between the two styles may not be so great as the article's author seems to imply with the "we're good, they're bad; we're intellectual, they're ignorant" language.

    I'll admit that my vaguely theist (perhaps post-theist?) leanings may be biasing my reading, but the difference between the two styles may not be so great as the article's author seems to imply with the "we're good, they're bad; we're intellectual, they're ignorant" language.

    I'll tend to agree that, on that point at least, the author was a bit to vague, quite possibly as a result of an editorial demand to keep the article down to a specified length. And, in the vagueness he let some inaccuracies slip in.

    Here's how I would have a crack at making the same points. First for the description of the scientific approach:

    In science you will almost always have observations that are not explained by current understanding of the physical processes involved. When this happens scientists adopt one or more of the following strategies to deal with the situation
    1. Try to repeat the anomalous observation, or reanalyse the data that produced that observation, to determine if it's a genuine issue or due to some experimental error. This would almost always be the first thing that's done.
    2. Run further experiments, or collect additional observational data (if, for example, your field is astrophysics there are limits to what experiments you can do you just have to look for instances where Nature does it for you), to explore how widespread the difference between theory and obsercation extends - is it just one example, or is it a more general issue?
    3. Tinker with the theory introducing minor changes to see if these resolve the problem (without creating new problems elsewhere).
    4. Devise a new theory that can explain both the previously explicable and the previously inexplicable observations
    In practice, assuming step 1 shows that the anomaly is genuine, different scientists will likely adopt each of strategies 2-4 in a (largely) uncoordinated attempt to determine the nature of reality.

    An example of this from physics would be the progressive recognition of increasing numbers of particles responsible for the observed phenomena associated with atomic, nuclear and particle physics. At first, it was thought that atoms were indivisible units; then it was realised that certain phenomena (eg: the way atoms bond in molecules and ionisation) could best be explained if the atom consisted of loosely bound electrons and a positively charged nucleus. The nucleus was thought to be indivisible, until is was realised that certain phenomena (eg: radioactive decay and different isotopes) could best be explained if the nucleus consisted of a collection of neutrons and protons. It was then found that there are other, heavier particles, similar to neutrons and protons - these different similar particles are called hadrons. The properties of these different hadrons were best explained if they were all composed of different combinations of three fundamental particles, which are called quarks.

    Now, for my summary of the Creationist (whether YEC or ID) approach:

    Creationists note that scientists observe various phenomena that are not explicable under current understandings of physical processes. Instead of trying to understand the extent to which these phenomena can be explained by variations to existing theories or the development of new theories, Creationists point to such instances and declare "God did it" (or, to try and fool people into thinking that they're not offering a religious viewpoint, "a clearly Intelligent Designer did it").

    Unlike the scientific approach which approaches inexplicable observations as a chance to better understand the underlying physical processes of reality, the Creationist approach to such inexplicable observations is to offer a blanket "explanation" that, if accepted, prevents further research into the physical processes of reality.

    There may be creationists who do this, but I think they're the exception. IME, they're more likely to misunderstand (or even worse, distort and fabricate) either the phenomena or the scientific explanation, and point to God/ID as the solution to the problem they just created. Fossil records and thermodynamics are common battlegrounds in this respect. If they confined themselves to inexplicable phenomena, their claims would be much more modest, and I'd be much happier.
     
    Posted by Alan Cresswell (# 31) on :
     
    Yes, you're probably right there. Perhaps a better version of that phrase would be:

    Creationists note that scientists observe various phenomena that are not explicable under current understandings of physical processes, or where Creationists claim that the explanation offered by scientists is incorrect and no other known physical process could account for the observation.

    So, Yeccies/IDers aside, where is God in all of this evolution stuff?
     
    Posted by Horseman Bree (# 5290) on :
     
    God, as Creator,obviously set the whole thing up, but it is quite possible that evolutionary processes are part of His way of doing the work of making our world the way it is.

    He certainly left us lots of clues in the rocks that he created, in the fossils that are all over the place, and in the DNA He used as His control on how we live.

    Denying that those clues are there is roughly akin to doubting the Word of God, ISTM.

    I know that sounds rather like some sort of Intelligent Design, but you're stuck with some aspect of that if you actually believe in a Creator.

    I tend towards Deism on that one, however.

    I think there are two logical answers to that question.

    The first is, more or less, classical Deism. God set everything up (including creating the laws that creation follows) and basically sat back and watched what happened.

    The second is, more or less, classical Theism. God sustains the whole of Creation by the power of his word (constantly commanding "let there be.." if you like). But that sustaining action is so embedded within the fabric of creation itself that we don't see it. The laws and regularities we observe in the physical universe simply reflect the faithfulness and consistency of the God who's sustaining all things.

    The advantage of Deism is that it leaves God out of the messy everyday business of the world, but it has difficulty reconciling miracles to the model. Theism has no difficulty with miracles, they're simply God chosing to sustain the world in a different way (for a short time in a specific location), but it does mean that God is then intimately involved in causing all things to happen - including all the nasty stuff like disease and earthquakes.

    The trouble with Deism, to me, is that the bible doesn't make God out to be a hands-off kind of entity (unless you're Marcionite, that is). Deism also seems to evolve into a god of the gaps, where God only exists in the unknowable (and questionably extant) beginning of time. Some god you've got there. Sits on his hands for all of eternity. No wonder Nietzsche thought he was dead.

    If by "the Word of God," you mean the bible, I think there's a big difference between doubting a human-produced compilation that's about 2000 years old and doubting evidence that's right before our eyes.

    At the same time, in a funny way, the rejection of scientific evidence seems more gnostic or docetic than Christian; God simply isn't in the things of this world, or God is a demiurge who created all these fossils to trip us up. The whole puzzle of the incarnation is that God is present in the world, through the holy spirit.

    "Creationist" in that article, and in most conversations, means "person with some bad science masquerading as religion, or with some bad religion masquerading as science," and at the same time, even the most liberal Christians on the spectrum prefer to call God the Father "Creator."

    Frankly, I've just never seen a systematic evolutionary Christianity that I've liked (though I have read some bits and pieces), which is funny because I'm actually pretty content with both Evolution and Christianity.

    I'll also confess that I tend to value miracles more for what they represent (or represented to their audiences) than as historical realities, and hope that this doesn't logically turn into a wimpy sort of liberal gnosticism.

    It's a fairly reasonable place to get some good descriptions of the latest conjectures from the Intelligent Design Creationism camp. It's a long way from unbiased (well, very few such sites are). I find their tag line "providing powerful new reasons from science to believe in Jesus Christ" somewhat misleading. For a start, their adherence to the ID conjecture means that in most cases they're presenting reasons from a pseudo-science, and as such I tend to find them not only not powerful but actually contrary to their aim - presenting the sort of misunderstandings of science (and Scripture) inherent in ID would be as likely to provide reasons for not believing the rest of their message about Christ. And, besides, though I do believe that there's nothing in science that contradicts Christian faith ... I don't think that looking for science to support the Christian faith is a fruitful exercise. In practically all cases the same scientific evidence can easily support a vast array of different religious or philosophical positions.

    I would suggest that the same answer that you were given originally still applies - Darwinism as proposed in On the Origins has long since died with advent of genetics. The principles of evolution still seem to be supported by the body of scientific evidence.

    It's worth having a look at an essay called The Imminent Demise Of Evolution - or, The Longest Running Falsehood In Creationism. It's a long (but by no means exhaustive) list of "Evolution is on its way out" claims from the 1820s to the present day, and demonstrates quite implacably that such claims may indeed be free of any ability to evolve. They're even worded almost exactly the same, from one decade to the next: increasing numbers of scientists are giving up on evolution and realising that it's inadequate, turning to God or ID or whatever as the mighty edifice of old science slips beneath the waves.

    It remains to be seen, as the article concludes, when this demise of evolution will become apparent to the rest of us. It's certainly not become clear from this thread, where evolution has been rather soundly celebrated and the various naysayers have silently stolen away.

    Perhaps the best argument that Behe is so mistaken is that (as was shown at Kitzmiller vs Dover) there's been a huge amount of good science done since then on the evolutionary origins of the systems he describes, and which he hasn't bothered to follow, whereas his approach hasn't been developed at all (least of all by him).

    I have no doubt that you find Behe persuasive. I just don't know why, as someone who doesn't understand science, you choose that over the scientists who are actually doing the science. It must be a theological stance, which is fine, but it can't be scientific.

    There's lots of science I don't understand (string theory!), and on such points I have no opinion - except when it clearly works. Do I understand what a photon is? Nope. Have I done the double slit experiment? Yep. Do I believe that quantum physics is accurate? Yes I do.

    Is that wrong?

    Really, one is either for or agin his views and theologically prejudiced, which of course, I am.

    I don't think it's fair to say that nothing's replicable on either side. Aspects of evolution are very repeatable - you can take a colony of bacteria in a petri dish, subject it to a change of environment, and watch it adapt. This has been done repeatedly, and is entirely as expected.

    What Behe's said is that this isn't enough, that it's mathematically impossible for such mechanisms to create the sort of complexity found in nature. His arguments have been examined and found to be wrong on many levels, by people who work in the field and who make practical and important contributions that others use and build on - qualifications that Behe, alas, does not have.

    I'm not sure that you can say that there must be something in it because of the intensity of the reaction to Behe's ideas. It is the stated intention of the Discovery Institute and others to change science education in the US to, effectively, give equal status to such ideas alongside the rest of evolutionary science. That would traduce science and it's that, rather than the ideas themselves, which is behind the strong defence.

    I think that history shows very clearly that you can fight back strongly against ideas without somehow thus admitting they're correct! Isn't that exactly what you're doing now?

    (I don't have much interest in reiterating Kitzmiller in detail - it's been done to death, and there are plenty of analyses out there if you feel moved to learn more.)

    Science is a way of moving on from "you're for or against an idea, and that's that" - indeed, that is its primary strength. If you don't think that's valuable, then fine. If you think it is valuable, but science doesn't do that, then fine. But in either case, it won't be possible to engage in a scientific discussion in any positive way, any more than I could start arguing points of Islamic theology.

    Rex Monday:Aspects of evolution are very repeatable
    Look, I am no Scientist so please excuse my ignorance and I realise that definitions of evolution, claims of what it is and isn't and what it does and doesn't do are very controversial.

    To me evolution is a theory of origins which has been said to account for the natural world. In popular parlance, it has been personified. In any doco by experts you hear phrases uttered in wonderment to the effect that evolution has created or enabled or selected or organised..etc.

    When it comes to detail however, Behe has had the temerity to point out that no one can actually explain how evolution was able to do X,Y,P Q, in his field of biochemistry. He is pilloried as a result but IMNSH opinion, he is actually right. It is all speculative. This is also what creationists point out. It is also what totally frustrates evolutionists who say 'at least our idea is better that 'Godditit!'

    In terms of lab experiments in biochemistry, sure they are repeatable. Sure, Miller points joyously to an experiment done by, (someone whose name escapes me)to say in Glenn Oldham's words (posted on this thread on 3/9/01)"..that they have a remarkableability to evolve complex systems." But Behe comes back to say 'Hey, but the researcher actually 'designed' that!' And so the impasse continues.

    Sorry for the double post.

    Well I don't know about this but maybe you could document exactly where he is proven wrong or someone else could. I'm sticking my neck out hugely here but I suspect it all comes down to arguments that claim something might conceivably have happened this way and not another.

    Regarding his contribution to knowledge, well, the the implied criticism here is not just in that he freely acknowledges the huge body of knowledge he works from. He just does not agree that the mechanisms of natural selection can account for what he has observed at a microscopic, organic level.

    Experiments are designed - how could they not be? - but that doesn't mean the outcome is designed. You're trying to set things up to replicate conditions, not create a mechanism to ensure an outcome.

    I mentioned the double-slit experiment earlier. That's very simple: you point a source of light at a screen with two slits cut into it, and see what pattern of light appears behind it. Designed, certainly, but what it reveals cuts straight to the heart of the quantum nature of the universe. Can you say that in designing that experiment, the experimenter designs quantum nature?

    Experiments reveal, not create. It's a crucial distinction.

    There is no impasse here.

    As for evolutionary science not producing an exact, proven pathway for things - it never claims to, and one of my personal frustrations with ID is that it says it expects this (even though it's not on offer) while constantly refusing to make any moves in that direction itself.

    Evolutionary science is about finding possibilities, not certainties: it's the fact that those possibilities paint a very logical, very consistent and very useful picture that makes it all worthwhile. The experiments help set the bounds of those possibilities, but they're by no means the only way of doing that. It's that they are of a whole with the other evidence that makes them compelling.

    Behe just says 'no' to a very small part of the whole picture, but has absolutely nothing to put in its place - and nothing to say about the rest of the picture.

    Where do you go from there?

    I read the article and his conclusions are:

    genetic mechanisms that produce variation are designed and are not products of Darwinian evolution.
    and:

    quote:
    Furthermore, this variation--often called microevolution--has clear limits and is unable to produce macroevolution.
    I don't see how either of these follows from the research described. No one is denying that bacteria bugger about with DNA in all sorts of interesting ways that go beyond mutational errors. No one is denying that these things can (under certain conditions) lead to rapid increases in genetic diversity, nor that this increase might slow down over time for a laboratory population.

    It doesn't address the first conclusion (are these characteristics of bacteria designed or did they evolve?) at all.

    It proves the first and uncontroversial part of the second conclusion (there are experimental limits to the amount of genetic diversity that can be generated - there must be: no one expects to grow elephants from E. coli within the lifetime of a researcher), but the second part (and therefore macroevolution can't result) is a non sequitur.

    What is it about this article that you find convincing?

    Well, Rex mentions 'logical' 'consistent' and 'useful' possibilities being the consequence of thinking in evolutionary terms.

    This guy obviously does not agree.

    "Arber concluded that the genetic mechanisms that produce variation are designed and are not products of Darwinian evolution. Furthermore, this variation--often called microevolution--has clear limits and is unable to produce macroevolution. Arber stressed that the knowledge of the "molecular basis of biological evolution" impacts not only "our worldview" in the areas of origins, but also has implications for the possible risks of genetic engineering..."

    The only point for me here is that I was asked, earlier, why do I ignore the 'good Science ' and why do I believe Behe when he has been so thoroughly refuted.

    Well, I want to know where the good science is and how exactly he has been refuted.

    The article mentions catch phrases people use like 'evolutionary pathways'. What Behe seems to show is that no one can actually identify such things.

    The stock reply seems to be that we cannot expect to know such things in detail.

    My comment to that then is: "Why is there such a huge investment in affirming them?"

    Jamat,
    You do realise that that article you cite is a complete misrepresentation of Arber which he has written to them to reject and which they have not taken down? (they have produced a very insufficent correction - but not removed the original)

    His statement on it is half way down the page here. Let me quote a little (English isn't his first language):

    quote:
    I recently got aware of an article entitled "Werner Arber: Nobel Laureate, Darwin Skeptic" that was published in September 2008 by the Institute for Creation Research and that is authored by Jerry Bergman, Ph.D. This article completely misinterprets my general conclusions that I base on several decades of studies in microbial genetics. A number of citations are taken out of their original context and surrounded by comments and misinterpretations by the author of the article. The truth is that I have contributed to advance scientific knowledge on biological evolution by studying molecular mechanisms of genetic variation. Genetic variation is clearly the driving force of biological evolution
    quote:
    In conclusion, I am neither a "Darwin skeptic" nor an "intelligent design supporter" as it is claimed in Bergman's article. I stand fully behind the NeoDarwinian theory of biological evolution and I contributed to confirm and expand this theory at the molecular level so that it can now be called Molecular Darwinism.
    You ask where to find 'good science' - well you won't find it on a site like the ICR, because they're not doing science. They're trying to convert people to a certain theological viewpoint - and as you can see in their treatment of Arber if facts get in the way, so much for the facts.

    Consider the plight of someone growing up in Eastern Europe under the Soviet regime who was only taught Party-approved history. They're taught stuff which is for the most part propaganda, with huge blind spots. Imagine that person then trying to understand European history and coming across someone like David Irving the holocaust denier, who was once a best-selling historian.

    They don't have the historical background to understand how badly out of whack Irving is. All they see is a seemingly well-written and footnoted and archival-researched history book. To someone who doesn't understand the context or the sheer weight of the evidence against Irving, those books look and read like proper history books. If the person reading the book is for some reason invested in anti-semitism, then he/she has no reason to question Irving. "Oh look" they might say, "This best-selling historian agrees with me!"

    If the person then looks at the trials Irving has been involved in and the horror with which he is regarded by actual historians, they could say the same sort of thing as you

    "And latterly, the maelstrom of flying feathers that was the reaction, really a kind of affirmation. It is clear that the whole historic community has such a stake in the holocaust being true, that whether it is true in fact has become irrelevant."

    The problem lies in starting from a position where theology/ideology has so far over-ridden basic science education that someone does not have the most basic of tools to tell when they are likely to be misled by a source. I can spot an anti-semitic website a mile away because I have a good background in modern history, and I know not to go near them for Third Reich history, if they show up in my search results, but if someone's been brought up to be anti-semitic and has not been taught basic history then such a site may look alluring and Irving may look like a real authority to them.

    You are in this position and don't know it. I wonder how many dodgy articles and sources you will end up citing from sites like this before the penny drops that these people are not doing honest science. By framing their misrepresentations as being in the service of religion, sites like this end up with honest godly people swallowing their bait and posting their slanders round the internet.

    Thank you for pointing out that Arber was misrepresented by ICR Louise. I honestly did not realise that they could be that slimy.

    What I read of Arber's statement does make me wonder what he makes of Behe.

    The following statement :

    "Together with non-genetic elements specific gene products are thereby involved as variation generators and as modulators of the rates of genetic variation. These are established facts that are based on experimental evidences and that are valid for the course of biological evolution as it works today in living organisms."

    seems to be precicisely the kind of thing Behe denies.

    Regarding the holocaust deniers' analogy, I would hope to be able to avoid some of those pitfalls though you surely can't believe that doubting that evolution occurs is in any sense the same as denying history from 60 years back.

    Incidentally, 'Schindler's List' is one of my favourite movies.

    Those involved in robot research have been building machines that evolve. [This is an article I found with a quick google. The conclusions from the full paper (which is available as a pdf) says:
    quote:
    We have described and analyzed a working example of an artificial autonomous agent. ... Through the evolutionary process Khepera has automatically and autonomously developed the optimal distributed control system to survive in the environment where it has been placed. ... We have neither pre-designed the behaviors of the robot, nor have intervened during evolution. The robot itself and alone has developed - starting from a sort of tabula rasa - a set of strategies and behaviors as a result of the adaptation to the environment and its own body. Despite its simple components and the simple survival criterion, it is difficult to control and predict the robot behaviour, due to the non-linearities and feedback connections exploited for optimal navigation and obstacle avoidance... (and arise from) ... the natural and logical result of the interaction between the physical characteristics of the robot and the type of environment.

    The only thing we can rely on IMV that is not influenced by majority rule and academic oscillation, is actually the Bible, the logos itself.

    The Basil Fawlty University of the Bleedin' Obvious, alas.

    Or something close to 20 years of dealing with conspiracy theories in my own field, and following the surprisingly similar debates on subjects like this.

    For instance, dealing with people who haven't the first idea of how to do academic history who expect me to take their Knights Templar fantasies about Rosslyn Chapel seriously because they've read stuff written by modern day wannabe Knights Templar and in their mind these people are 'historians' and they think the websites by these groups and the puff-piece books they sometimes write are reliable. They don't realise the response from anyone with the first clue about medieval church history is going to be either to fall about laughing or groan at seeing this nonsense again. They then get very huffy, and start accusing historians of a conspiracy to suppress 'the truth' (which if you knew anything about historians, you'd find hilarious too). What can you do? They haven't got the first clue, they don't have anything like the background for evaluating primary and secondary historical sources which would even get them to square one, yet they expect to be taken seriously. You don't know whether to laugh or cry.

    I've seen enough misrepresentations by various creationist websites addressed over the years to know their standards for science seem to be so low and their likelihood of misrepresenting stuff to fit their agenda is so high, that they aren't even worth citing to people who deal in actual peer reviewed science, (though some of the board scientists are kindly enough and have the patience to bother refuting this stuff). Of course when they do, back comes the person with another similar offering from another one of these dodgy sites without the penny having dropped that they're searching the scientific equivalent of the National Enquirer or a Scientology tract and that they're never going to find anything of any useful standard of research there.

    I tend to look at this from a historian's point of view, if people use sources known to be very unreliable, they are going nowhere with the argument. Not even to square one. Using those sites is, in my experience, a waste of everyone's time.

    It's what happens when an entrenched idea meets fact/findings which disprove it which makes the difference. If you're Einstein or Newton you are not only able to think out of the box but then able to show/suggest the sort of findings which will eventually prove your new theory to have great explanatory power. then when other people look for those, they find them in spades. You show how your new theory makes predictions which can be verified (my more learned scientific colleagues can correct me here if I am getting this wrong). This is what creationists have to show, if they're going to have any credibility. Unfortunately for them, it's their opponents who've turned out to pass this test.

    I think this is based on a poor grasp of the history of this topic. The people who started in the closet worrying about being sacked were the people whose views contradicted powerful churches and religious sentiments. It took a lot of experiments, findings being reported, and people checking things out for themselves for matters to shift, and they shifted over the past few hundred years because there was such an enormous preponderance of evidence on things like evolution, the age of the earth, the various flaws in the Noah story etc. You wont find many closet creationists and flood geologists for the same reason you wont find many people who believe in phlogiston or the four humours or physiognomy, because that stuff has been investigated over a long time span and academically beaten to death beyond recovery.

    The only reason you do still find the occasional person trying to punt this stuff academically is for the same reason that I have family members who have claimed to be Knights Templar, because emotionally people can be so invested in it because of their beliefs, that added to complete ignorance of how history/science works they're able to ignore or dismiss otherwise overwhelming evidence.

    The reason you won't get it in a peer reviewed journal is for the same reason you wont get nonsense about the Holy Grail being buried under Rosslyn Chapel in the Scottish Historical Review any day soon, because the idea of having such journals is to allow people to sift interesting ideas by people who have some chance of being right from stuff which is a load of fetid dingoes kidneys to start with. For the same reason, you won't be seeing me competing at the Commonwealth Games in the 100m sprint, not because there's a world athletics conspiracy against unfit Scots historians, but because I can't run for a bus.

    You do of course, for reasons of money, eccentric belief or personal advantage get people who set themselves up as gurus for proven academic nonsense, despite the fact that they ought to be qualified enough to know better. People who don't realise how far out of whack they are, then trumpet their credentials, and uncritically cite their stuff. It was ever thus.

    The thing is that these people usually have no bother publishing their books, or websites and even getting entire TV series, if it sells well enough or is sensational enough. Nobody censors them, they just open their mouths and it then becomes clear why they haven't got academic jobs - because they're talking pap that any competent scholar in the field could debunk - good enough to fool people who don't know much, who want to believe in Holy Grails under the nearby Kirk or aliens visiting Earth or whatever, into parting with their spondulicks, but not good enough to fool a peer reviewed journal or hiring committee.

    Of course such bodies can be fooled, but then again, when people go and double check what's been published and try to take the dodgy findings further, sooner or later the fraud or mistake tends to get found out. That's the system working as it ought to.

    A bit of European Reformation history is enough to indicate how far off base this is. Many of the Reformers had a touching but naive humanist belief that you just had to let people read the Bible with a bit of guidance from the pulpit and they'd all come to the same 'correct' conclusions. Imagine their surprise when people started questioning even the formulations of the creeds, coming to radically different conclusions and doing things in the street which frightened the horses. Biblical interpretation turned out to be very far from some stable universally agreed thing subject to neither majority vote or academic oscillations! You can't have the Bible without that pesky thing, the reader/interpreter with all his/her subjectivity. You can try the cop out of pretending the Holy spirit will never let you err in your reading, but again it's worth reading a bit of history, and seeing where that got people when the Spirit was apparently telling one bunch of Reformers one thing and another lot something else.

    I think those notions are as far off theologically as they are scientifically.

    I don't know if I'm really in the more learned group, but I would like to rephrase this a bit.

    Putting a new theory in place:
    Compose theory
    Show that it explains everything the old theory did
    Show that it explains things the old theory did not
    Suggest ways to further prove the theory (if you can think of any)
    [subject to revision by the actually more learned! [Smile] ]

    Number 3 is the biggie in this. If a theory doesn't explain the current equal/better *and* explain some of the unexplained questions, there's no point in having it. I'm also leaving off the "prediction" portion since, as IngoB (I think) has pointed out in Purgatory, evolutionary theory does an amazingly small amount of prediction, unlike physics, for example.

    This is why IDers/creationists need to start putting forth some sort of positive hypothesis/theories in order to be listened to (excepting the rare "IDer" with views like Alan Cresswell, etc). They're just going forth and attempting to poke holes in current theories, doing a piss poor job at that, and not giving anybody an actual alternative.

    Any attempt to replace evolutionary theory alone (which is only one of many theories upon which our old-earth understanding rests) would be an insanely large undertaking. There's 150 years and millions of pages of research findings to explain (and exabytes of data!). Good luck to any who try.

    I'm not sure I can agree with this. Evolutionary theory predicts things like antibiotic-resistant bacteria and pesticide-resistant weeds, which we've seen borne out. It predicts both increasing diversity and complexity of species over time, which has been borne out in the fossil record (with a few breaks for mass extinctions). It predicts that physiologically similar species should also be genetically similar, something which was also borne out once our understanding of genetics was sufficient to put such a proposition to the test. Those are just three big ones that occur to me (a non-biologist) without having to think that hard about it.

    Indeed.

    It was also designed to take that into account, so it's not really a prediction per se.

    This is the big one that's highly problematic. For classification, genetics is the trump card. Zoology (what's left of it anyways...it seems to have transferred mostly to cladistics) plays a game where they re-align phyla based on genetic data (sequences of a group of proteins, rRNA sequences, etc) and then are constantly playing catch-up to find a new physiological property by which they can also be grouped. If you look at current research papers in zoology, you'll find that we're constantly re-aligning organism classifications, even at the phyla level (though the Linnaean categories make no actual sense scientifically).

    We aren't learning much about organisms big-picture-wise by looking at physiology now. We're trying to keep zoo from having no power whatsoever. Yes, you can say that we will still put new organisms into categories based on physiology, but what use is that if we're regularly regrouping these since we don't really have an understanding of what features are important?

    On the flip side, we're finding an amazing amount of diversity among organisms within a species. (note, this is very new research and only seen in bacteria so far). Eric Kirk (iirc, I can look in my notes if any are interested) has found bacteria which are 99.7% similar at the 16S rRNA level (a similarity which places them very confidently within the species, and I think at sub-species level as well) which differ by up to 25% sequence identity at the whole genome level! They were from an almost identical (macroscopically) environment as well. I don't expect similar results to be found among "higher" eukaryotes (in terms of low %age sequence identity for whole genomes), but we still don't have that many whole higher animal genomes to work with yet.

    A simple statement such as you made is not untrue. It's not very reflective of the reality though, which is that the theory as we have it now has been recrafted to fit the data that we have so it's hard to call it prediction. Will it get there? Very possibly. Is it very strong as it? Most certainly. But I'm not sure we should be using the same terms as physics or chemistry does when they talk about their theories.

    I don't think I advocated the approach of just reading scripture and interpreting it how you want. However, we do have the Bible as a guide and as a way of comparing what other sources tell us on things. The point for me is that it exists and it is authoritative as a reliable indicator of truth. nothing else does this.

    To take a few examples:

    Christ was actually predicted by prophesy. Cyrus was named by Isaiah before he was born. The Babylonian captivity happened. The Jewish state exists against the odds. No one apart from conservative Bible scholars in the 19century predicted that (One Robert Anderson, founder of Scotland Yard did so.)God tells us certain things, if we indulge in them, will harm us. Christianity has gone from Jewish cult to world religion. Jesus predicted the AD70 disaster in Matt 24 (not one stone left on another.) It happened. the fact is that one ignores the Bible at one's peril.

    I have no problem with where the Holy Grail may or may not be secreted according to Dan Brown or whoever might be barking enough to take him seriously but I do have an issue with comparing historical charlatanism with trust in the Bible.

    Jamat - one of the big issues with some translations of the Bible - ask Tom Clune about the NIV if you want chapter and verse - is that they are translated to make the prophecies point to Jesus. Others disagree that those prophecies did so - there are at least two whole religions who disagree those prophecies point to Jesus as the Messiah.

    Some scholars believe the Gospels were written post the destruction of Jerusalem - very easy to predict something that's already happened - or read that event into what was said with hindsight.

    How much does the existence of Israel depend on people forcing that to happen to tie into their visions of scripture?

    It's hard to know what to say to this, because you clearly think it's a knock-down argument, but it's just a weak mish-mash of "what are the odds?" and special pleading. You do understand the difference between making precise, accurate predictions and identifying vague and tenuous parallels after the fact, while the "predicted" events are being documented, right? Because using your reasoning, Nostradamus should be accorded the status of Holy Writ.

    I kind of hear the patronising tone of "Oh lets humour the poor naive conservative evo here."

    I don't think anything is a knock down argument at all. God in the Bible does not give us that kind of indicator. That would make it a bit too easy. It is actually all about the heart and not the mind. If you will excuse the 'naivete,' Jesus said "he who has ears" and all that. It is certainly possible to rubbish the Bible and put it onto the level of Nostradamus. To me this is a straw man and intellectually dishonest. To do it, you have to accept all kinds of scholarly presuppositions and certainly lots of clever people do this. The question is how intellectually compelling is it to do so.

    I can quite reasonably accept a late date for the Gospels for instance. If I did I'd be in good company. However, no liberal scholar meets the challenge of why a late date for say 'John', doesn't explain why he wouldn't mention or imply any knowledge of thr events of AD 70. Quite a reasonable conservative scholarly view is that this is because they hadn't yet occurred.

    My point is simply that there is no smoking gun that blows bible prophecy out of the water. I actually do not think it unreasonable to look at Daniel 9 as written hundreds of years before Christ was born..and yet it predicts him. To dismiss it, you have to assume the events are written when they had already occurred. The main reason this happens is a presupposition against the supernatural.

    However, this thread is about the 'death' of Darwinism. One no less than Francis Crick himself postulated 'panspermia' I believe. This is the belief that we were consciously placed here in seed form by aliens. Correct me please but Crick's reason for this is the impossible odds of the building blocks of life combining spontaneously? Sounds to me like he has a lot in common with Behe there. Even given 5 billion years, he doesn't think life could have arisen by chance.

    I thought you'd already established that to your own satisfaction with your straw man comment. How kind of you to describe me as "intellectually dishonest", as well. I have no idea what "scholarly presuppositions" I'm meant to have accepted, so I have no idea what I'm meant to be defending myself against, but I feel very confident that I could find a "correct" prediction by Nostradamus for every one you pick out of the Bible.

    Er, no. You only have to recognise that the "predictions" in Daniel are vague, poetic and non-specific, and that they would have been well-known to all Jews, not least the evangelists, in 1st Century Palestine. If we had an objective, comprehensive account of the events of Jesus' life, rather than oral accounts circulated among people who had a particular view of his life and a common frame of reference, I might pay a little more attention. I'm not saying the fulfilments of these prophecies were fabricated necessarily, but I would be astonished if the stories didn't subtly, unconsciously take on aspects of the well-known prophecies in their telling and retelling.

    Scientist expresses unorthodox view shock! There may be good arguments against evolutionary theory (I don't think there are, but the issue is often confused because one name is given to a whole range of influences and processes), but arguments from incredulity are weak.

    You really ought to read this book, and see just how much of the Bible doesn't track closely with archaeology pre-700BC (i.e. most everything pre-exile). Doesn't mean there is some truth in there, but we can't take it even remotely literally.

    I'd say to make it better propaganda. I'm sure others here can provide better explanation. Perhaps even it was written before the Temple burned (though only one person seems to have tried to argue this, originally as a joke, and nobody appears to have taken up the challenge in 40 years, so I'm not sure how strong the arguments actually are). Still this does not say that the Bible can be treated as raw truth (hint - not even close).

    You miss the mark pretty wildly. Crick postulated panspermia since that would then require life to start from nothing only once in the universe, rather than separately on each individual planet. If you go through the wikipedia page on Crick, you'll also see that he has backed down from this view on evidence that RNA has more enzyme properties than we knew then, and is a likely precursor (at the time they were attempting to explain proteins as the precursor). It is **NOT** an ID argument.

    See above, and I suggest you read more before you prognosticate. It took me about 3 minutes to show this idea is silly. It also is nothing like what Behe is talking about, as it related to abiogenesis and *not* to evolution. They are separate. things.

    Well, no, Drosnin's book The Bible Code II, in which he mentions speaking with Crick about transspermia, was published in 2002. The conversation between the two of them had to have been earlier than 2002.

    I have not yet found online at what point in time the conversation allegedly took place. In the version of the conversation relayed in this online article, Crick doesn't exactly give a ringing endorsement of transspermia, he just admits that he believed it at one time (doesn't say if he believes it now) and relates that according to the theory it was by spaceship and not by meteor that the spermies are transmitted. It's quite possible to read the version I link to as not admitting anything at all about his beliefs regarding transspermia at the time of the interview.

    And as the website points out he was already publicly backing away from transspermia in 1981.

    What you describe is only one branch of physics: theoretical high-energy particle physics. As much as many particle physicists would like to pretend they're the be-all and end-all of physics, they're merely a sandbar in the vast and diverse archipelago that is physics.

    Physics in general is actually an extremely practical science, it's just that a lot of the time it's impossible to predict how a certain line of research will yield practical results. iPods and all their ilk, for instance, were made possible by the discovery of a physical effect called giant magnetoresistance, a discovery which won the discoverers the Nobel Prize in Physics a few years back. Most physics research is in areas like this with obvious applicability. Like most people, most physicists prefer to do work with practical value. High-temperature superconductors, which could revolutionize all kinds of things if mastered, is a HUGE area of research. The vast majority of the technological advances of the past 2-3 centuries owe their existence to developments in physics, and it's entirely probable the trend will continue.

    It's also worth pointing out that theoretical physicists are a minority no matter which sub-field they work in. Experimentalists are way more common. I think most people would find shooting lasers at things a lot more fun than poking at equations all day long, and physicists are no exception.

    First few sentences of the Wikipedia article on radiation capture the double-usage rather beautifully:

    quote:
    In physics, radiation describes a process in which energetic particles or waves travel through a medium or space. There are two distinct types of radiation; ionizing and non-ionizing. The word radiation is commonly used in reference to ionizing radiation only (i.e., having sufficient energy to ionize an atom), but it may also refer to non-ionizing radiation (e.g., radio waves or visible light).

    I wouldn't necessarily call them "distinct" types of radiation since to me that implies that they are intrinsically different when the only difference between ionizing and non-ionizing radiation is energy, an extrinsic property. I would divide them into electromagnetic radiation and Everything Else. I'd call it nuclear radiation, but nuclei can radiate electromagnetic waves too. [Razz]

    But that's all just pointless semantic hairsplitting, so I'll let it go out of the goodness of my heart.

    There are definitely enough pedants on the Ship that I really should have known better ...

    Any classification of radiation is going to be problematic. Ionising/non-ionising simply puts an arbitrary division based on energy (and not well fixed ... ionising what, exactly?). EM/not-EM implies that one sort of wave/particle is intrinsically different from another ... EM includes radiowaves and gamma rays which have origins and properties that are far more different than, say, gamma rays and beta particles; non-EM would include electrons, neutrons, protons, alpha particles, heavy ions, muons, neutrinos. Nuclear/non-nuclear also doesn't help much; accelerated electron beams are non-nuclear but very similar to beta radiation (a difference in energy distribution), atomically sourced x-rays can be more energetic than some nuclear gamma-rays, and accelerator sourced synchrotron radiation is yet another EM source that's non-nuclear but with properties that are very similar to nuclear radiation.

    So, just to be clear, I tend to zap things with visible light (from lasers and LEDs depending on focus requirements) and beta and gamma radiation. I also tend to measure gamma and beta radiation, and single photons of visible spectrum light. And, it's all good fun without the need to worry about 11-dimensional space at all.

    I never got to play with beta or gamma radiation when I was in university, sadly (for me, at least; I'm sure the rest of humanity breathed a sigh of relief), but I did get to play with pretty blue argon lasers. Shiny...

    Maybe I should leave it at that before people realize that the reason people study physics isn't out of love of science or desire to benefit humanity but so they can play with really big expensive toys. [Two face]

    It's also worth pointing out that theoretical physicists are a minority no matter which sub-field they work in.

    I was being a bit facetious. But then I was prompted by the silly notion that something has to be predictive to be good science, and the even sillier one that evolutionary biology isn't.

    If they want predictions from evolutionary biology and palaentology, how about that there had to be a mechanism for keeping the Sun and the Earth hot for hundreds of millions of years? The biologists and geologists new the world was at least 200-400 million years old (and pronbably a lot older), because there are extant sedimentary rocks that took that long to lay down - it is, as they say, bleeding obvious when you start looking. But the physicists didn't belive them until they thought up nuclear physics.

    Predictive power of Natural History, one; Lord Kelvin, nil.

    Or what we used to call "continental drift"? Again, its pretty obvious from looking at fossils that parts of the continents now separated by oceans were once adjacent. And we can reconstruct not only the ancient Pangea but also the continents it split into.

    For example Australia, many Pacific islands, India, South America, and Antarctica share many of the same fossils from the early Mesozoic, as do Europe, most of Asia, and also North America.

    Once we get to the early Tertiary then India and Africa get more Asianised. Though some southern animals (like elephants) turn up in the north. South America stayed uniquely Gondwanan until the Pliocene. Then, hey presto! It gets fossils of camels and cats and bears - all the way from Asia originally. North America gets marsupials and armadillos in exchange. Australia remains southern (apart from bats) until humans, dogs, and rats mysterriously turn up together a few tens of thousands of years ago, and New Zealand and New Caledonia are until people arrive a few centuries ago.

    There has got to have been an series of temporary interchanges of land animals and plants between continents - Wallace spotted that in the mid-19th century. Most writers invoked rather stringy vague land bridges. A few - Alfred Wegener and Arthur Holmes most famously - came to belive in what was then called "continental drift". Which turns out to be true. But its forty years before the geophysicists and their friends in the CIA discover the magnetic anomalies that allowed them to think up plate tectonics.

    But there had to be something - because the actual course of the history of life on earth required it. Hows that for predictive power?

    Sorry, I haven't been able to spend any time here for a while.

    If you read my posting as saying that evolutionary biology isn't good science, you're reading something that I never intend to write. If you read it as saying that it's not predictive then you're reading something I never intend to write (though I may have overstated this...I'll need to go back to check). It's not bad science. Hopefully I wouldn't be fascinated with it if it were. I do contend however that evolutionary theory is very different than how the normal populace views science, and that these differences cause many of the problems people have with it.

    College educated non-scientists won't get much beyond knowing that if you heat up a gas in a balloon, then you can say how much larger the volume (or pressure) will be. How if you drop a ball from a certain height, it will hit the ground with a certain force. How much and what product you can make from a chemical reaction. Etc. Very deterministic.

    Then evolutionary theory comes along and is unable to provide detailed answers to what seems like much of anything. Nobody can answer Behe's demands for detailed step by step walkthroughs to the pathways he contends. It's not a failing of the science, but it is a limitation. It doesn't work in the same deterministic framework that people see in general science.

    To this average Joe, it sounds like a whole bunch of hand-waving uselessness and very unscientific when somebody posits scaffolding as a potential mechanism to get around (purported) irreducible complexity. While those claims are false, I think the differences should be acknowledged and explored in depth when speaking of or teaching evolution.

    Ken,

    You're entirely missing the point. It's about communication. "We" have failed to communicate evolutionary theory in a fashion that seems even remotely scientific to people who are questioning it, and left it open to misrepresentation. Even if what they're saying is false, it doesn't matter if it's enough to make people fall for it.

    I don't think it exists, though you seem to think I do. It doesn't matter though, because when people expect biologists to be able to provide firm answers like they've seen from chemistry/etc, and we can't, then it looks like a weak or unsubstantiated theory.

    IMO, we make it easier for people to make these ideological attacks by poorly presenting the material and not teaching well the proper expectations for what science does/can do. If we're going to teach evolution to pretty much every schoolboy and schoolgirl in the world, we need to do it in a way that works. Which I don't think we do now.

    No, I don't think I would. What is this "determinsitic framework"? Physics has been weird and getting weirder for a century or more. Do people understand relativity, quantum mechanics, the statistical/stochastic nature of physical and chemical processes, the built-in indeterminacy of things, the relationship between electricity and light? (and that's only taking physics up to where it was in my grandparents time) I'd live to be wrong but I suspect that most people have very little accurate idea of all that at all. Most of them are more likely tounderstand the basics of biology.

    And I think that on average people probably have a better understanding of biology than they do of those other sciences. Because you don't need to do maths to understand most of it, and most peopel arent; very good at maths.

    There is no real challenge to the usual understandings of biology from this ID mob. It woudl be a lie to pretend that there is. Making it seem far more important than it is.

    What are these hard questions we ought to be able to answer, but can't in a way that physicists can?

    But we do. Its probably far easier for most people to understand biology than chemistry or phyisics, and I think its probably better taught than the other sciences in schools. Or maybe less badly taught would be fairer. Also - and this is important - the popular literature about biology is on the whole much, much more accessible - as well as being much larger - than that for other sciences. And even TV programmes.

    People who do real science write easuily accessible books about what they actually research on in a way that doesn;t happen in the other sciences to the same extent. I don't think that's reflects anything bad about the phycicists, just that the nature of what they study is harder to get over, because its much more alien to the way people naturally thik.

    I have not yet found online at what point in time the conversation allegedly took place. In the version of the conversation relayed in this online article, Crick doesn't exactly give a ringing endorsement of transspermia, he just admits that he believed it at one time (doesn't say if he believes it now) and relates that according to the theory it was by spaceship and not by meteor that the spermies are transmitted. It's quite possible to read the version I link to as not admitting anything at all about his beliefs regarding transspermia at the time of the interview.

    And as the website points out he was already publicly backing away from transspermia in 1981.

    The Drosnin book, published 2002 (I don't know when the interview was but understand it was a phone interview), claims, (apparently), that Crick has not backed away from his view in effect and my cursory reading of the link you posted suggests that such is a reasonable interpretation. Please point out what I may have missed.

    The issue is that someone of Crick's stature does not regard as possible, any scenario in which the DNA helix could have randomly arisen. Nevertheless, it exists. Therefore, another scenario is responsible than neo-Darwinian evolutionary development.

    Perhaps your post should have been prefaced with "Well, yes.."

    I think that the comment above demanding definition of irreducible complexity maybe is expecting it to be seen as a theory? This may not be the case, Ken, but in Behe's book, it is simply a way to describe the abstract notion that some biological structures are so composed that they could not have occurred through gradual cumulative improvement. The complexity of the blood clotting process, for instance, is such that it beggars belief to suggest it could have occurred by chance.

    Jamat, did you follow through the links I gave you on robot design? Those researchers were providing a random form of 'evolution' for robots, by adding another couple of units to the system every few generations. When enough capacity had built up the robots evolved in unexpected ways to solve predictable problems - the same sort of things that you're saying are inexplicable.

    Well, it's self evident that the DNA helix could not have arisen randomly. That doesn't rule out the neo-Darwinian explanation, since that isn't random either. Evolution is a process with a random element coupled to selection pressure - the results of which are not going to be random. If you want a non-biological analogy then you could cite the example of gases - they exhibit non-random characteristics, expressed in the classic Gas Laws, but are composed of individual molecules zipping around in an essentially random way.

    There is by your admission randomness as a necessary part of evolutionary change. That is precisely what is in question. And the whole issue concerns the fact that biological knowledge does not readily sit well with evolutionary type progress. The gas analogy is fine as an analogy. Behe's point is that no one can identify a viable possible pathway that is anything like specific. Glenn Oldham's posts earlier in this thread are plausible only if one grants the number of 'probablys' he uses.

    Yes, randomness is part of the evolutionary process. It is the part that provides genetic variation. But, the powerhouse of evolution is directed - natural selection of those variations that produce increased fitness to the environment the organism lives in. That powerhouse is extremely powerful, and is capable of producing very complex lifeforms and organs. It's produced eyes on several different occasions. It's produced all the examples of 'irriducible complexity' that Behe claimed. All by small changes which are each fairly probable from random mutation, cumulative through slightly more advantageous processes to the version we have today ... and possibly tommorrow another random variation will result in a very small improvement that will pass rapidly (in geological terms) through the whole population.

    Perhaps there is a widespread misunderstanding that evolution is linear - that one random variation occurs and is selected or rejected, then, sometime later, another occurs.

    I seem to recall reading recently an argument that, despite human intervention, there has been insufficient time elapsed since the domestication of wolves to produce all the genetic variations required to explain the range of dog types, St Bernard to Yorkshire Terrier via Greyhounds for example. The answer, which seemed reasonable to me, was that that since most genetic variation is neither immediately beneficial nor harmful the wolves had a vast reservoir of modifications which were unused until man selected for them.

    To my mind it takes an odd definition of "intelligent" to apply the concept to a designer which provided us with eyes which are "inside out" (though I believe it got it right with squid?) and provided an unnecessary complication which means that we can choke to death by passing food into our airway via a ridiculously unnecessary crossover.

    To say, Alan, that directed natural selection is powerful is certainly nothing that any creationist would dispute. They would just say that along with dog breeding etc, that it is not the issue or the point. What they dispute is the likelihood of any random genetic variation being beneficial. Behe actually comments on the e coli research that while for one mutation to select itself as beneficial for the organism is remotely possible, two or more would in fact be required and this is way longer odds. Behe, of course, says he is not a creationist.

    He's plain wrong then.

    There are about 5 million basepairs of DNA in a typical E. coli genome (there is huge variation between them - some can be up to 20% larger than others) That means there are about 40 million possible point mutations in the genome - that is a change in a single DNA base, for example any DNA base can be deleted, or one of the four others inserted next to it, or (much the most likely) changed to one of three others.

    Point mutations occur in bacterial chromosomes about once in 100,000 cell divisions per base pair. So you would expect about 50 per generation per cell. Most are of course soon lost or repaired, or are selectively neutral. Perhaps very roughly one in a million of all possible point mutations occurs per cell per generation. So a population of many more than a million cells will have every possible point mutation every generation. The chance of any given two mutations occuring simultaneously is perhaps about one in a trillion per cell per generation. So a population of a trillion cells will have every such double mutation every generation on average.

    There are probably a few grams of E. coli in a typical human gut. And the same - varying for allowing for size - goes for every mammal in the world and pretty much most other large animals as well. Off the top of my head, I guess a gram of E. coli contains over 100 million cells. So the population per human is of the order of hundreds of millions. So every possible point mutation is occuring many times in every generation in every human gut. Every possible pair of mutations is occuring about once a generation, perhaps a little less, in every human gut.

    The generation time is perhaps one an hour (its 20 minutes or less in culture in a lab) so there will be over a trillion trillion E. coli point mutations in your gut in your lifetime. And in mine, and in Michael Behe's and so on. Work out the mubers for yourself - I'#ve probably slipped a zero somewhere. So each of us will probably have experienced every possible pair of such mutations inside our own bodies. And a great many - millions and millions - of simultaneous triple mutations.

    But there are billions of humans. And these bacteria live in other species as well. And you can find them in open water and in the sea (where it is evidence of contamination by mamallian faeces - not that there is any lack of that. Oh, and in sewage.


    Whats the total population? Back of an envelope, say each human is associated with about 10 kilos of gut content or recent faeces (mostly distributed through the sewage system or the environment of course) So that's ~6*10^9 humans, so of the order of 10^11 kilos of gut content & poo. Say that 1 part in a thousand of that is E. coli or similar (likely an underestimate), 10^8 kg of them in humans. Say that humans represent 1 part in a thousand of all the E. coli hosts in the world. So perhaps 10^11 kilos of the species in the world. As there are maybe 10^11 cells per kilo that is 10^22 live E. coli in the world. Say of the order of 10^25 point mutations per day.

    Total number of possible such mutations is of the order of 10^7. So somewhere in the world every possible combination of 3 simultaneous point mutations will happen in E. coli every day many, many times. Every possible combnination of 4 every day or so. There have probably been of the order of 10^11 or 10^12 days since this kind of bacteria has been around. That's a lot of mutations.

    NB point mutations probably aren't the main source of genetic variation in bacteria, whole-gene mutations are common, such as reversals or the insertion or loss of an length of DNA, and there is considerable opportunity to gain genes from plasmids or horizontal gene transfers. So looking at point mutations gives us the absolute floor of the likely rate of recruitment of genetic variation.

    NB also that selection is going on so unworkable mutations are thrown away and the next set of mutations starts, by definition, wth viable combinations.

    NB again & very importantly that bacvteria can share genes so if a useful one turns up in one place it gets everywhere.

    NB also that it is not necessary to see every possible mutation - despite their vast numbers all extant bacteria make up a tiny proportion of all possible genomes of that size

    (there are about 1000 possible combinations of 5 bases of DNA (4^5 = 2^10 =~ 10^3) - so 5,000 base pairs have 10^3000 possibilities and 5 million 10^some big number I can't be bothered to write down)

    I honestly don't think I know enough to explain it. Dawkins' latest, "The Greatest Show on Earth" calls such things 'hairpin' I think. What he means is points of change in the genealogical line of somthing where it begins to 'morph' into something else.

    There's nothing but unsupported assertion on that blog. And people who tried to make some sensible comments about numbers just get banned.

    There seems to be something about evolution that Behe and his friends just don't "get". Their arguments - as far as I can tell - miss the mark so badly its hard to see what they can be thinking.

    Its almost as if somone was trying to refute the existence of Australia by saying that upside-down people would fall off the world.

    That's not what he means by "hairpin" at all.

    The idea is that we are all connected through our common ancestors. But we can only know what those ancestors were like by comparing their living descendents and seeing what they have in common.

    So there are no such things as "missing links". The connection between a crocodile and a duck is not a blend of the two, not a crocoduck, but the last common ancestor of the two which probably wasn't very much like either.

    So if you wanted to describe how a duck is related to a crocodile you would have to follow the ancestry of each back in time until they merged. The techy term for that is "coalescent" but Dawkins calls it a "hairpin" presumably because it has two long branches that meet at one end.

    Dawkins describes it in an interview here:

    quote:

    Lundborg: Could you explain the idea of the hairpin bend?

    Dawkins: You start with any modern animal you like, such as a rabbit, and put her next to her mother and then her mother in a chain that goes back in time a very long way until you hit the common ancestor with some other animal such as a leopard. It would no longer look like a rabbit but more like a shrew.

    You call that the hairpin bend and you turn round and start going forward in time. You just keep taking the fork that leads to the leopard and in time you’ll get to the modern animal.

    Lundborg: This works with any pair of modern animals?

    Dawkins: Yes. At every stage of going backward and forward, every animal would look like its mother, yet after millions of generations you would see a gradual change.

    Right, as Ken says, that's really not what Dawkins means by the hairpin. The hairpin in how many generations you have to go back before your great(however many times) grandparent is the great (however many times) grandparent of a particular someone else. For your first cousin, the hairpin bends at your grandparents. For you and me, we'd have to go further back than that, but if we went back through the generations at some point there would be someone who was the common ancestor of both of us. This is less weird than it sounds because remember that you have two parents, four grandparents, eight great-grandparents and so on.

    I think a lot of the problem people have with understanding evolution is that they don't really get which bits are random and which bits aren't. So they overstate the random processes and say "You think that humans just showed up completely by chance?" or they overstate the non-random and say "So things are just getting bigger, stronger, smarter and better, forever?" Evolution doesn't actually claim either of those things but they're probably the two most common criticisms. Evolution by natural selection is actually a very simple concept (although like anything if you go into it in a lot of depth it can start to make your brain hurt): a combination of mutation, which is random, and selection, which really isn't.

    This is why I picked up on your "mutation selecting itself as beneficial" because it seems like a very weird phrase to use. Mutation doesn't select itself. Mutation just happens, all the time. The environment may make a particular mutation beneficial, but that's different.

    Ken's not the one trying to blind you there. Behe is. Behe's running an argument that he tried in the Dover trial (where the conservative (Bush-appointed) judge termed the creationist side "Breathtaking inanity"). And to cut a long story short, the chance of such a mutation group happening spontaneously in any given e-coli is miniscule - Behe is right there. But e-coli is incredibly abundant. To the point that when I ran the numbers myself, I worked out that it would have happened several times in my parents' back garden per day (I live in a flat). I couldn't be bothered to run the numbers on a window-box...

    Not just me. Taking Behe's supposed mathematics apart has been done to death to the point that in the his testimony at the Kitzmiller vs Dover trial he himself accepted that even using his own conditions to make things as unlikely as possible, irreducibly complex systems would evolve and be fixed in a population in 20,000 years.

    Behe's argument is not mathematical in the slightest. It's an argument from incredulity dressed up in the trappings of mathematics, and when actual numbers are plugged in the whole argument is shown to be fallacious.

    Great Links!Thank you.

    I still think Behe wins this argument despite what the court says.

    I agree it is not about Mathematics (the trial)

    However, Behe's book is about the impossibility of the mathematics if chance is allowed to be the arbiter of evolution.

    I love the following quote from his introduction.


    "The complexity of lifess's foundation has paralysed science's attempt to account for it." (Darwin's Black Box,P 4
    Touchstone ed.ISBN 0-684-82754-9)

    At any given point in history, there are tons of things science can't "account for." Then foolish Christian apologists latch onto these things and use them to beat science about the head with, and then are made to look like complete asses when science finally gets around to accounting for them.

    It's all in Lewis. All in Lewis. What do they teach them in these schools?

    Too bad mathematics, science, logic, and reason disagree with him on all of it. That's usually the point when I stop listening, and would prefer to read the awesome remarks of the judge's decision.

    You are going to have to explain why because his arguments seem to make no sense from here.

    Many people, including me, have posted reasons why he is wrong here and other places on this website. You haven't argued against what we said, or made any real reply, just asserted that you think there is some truth in this "irreducible complexity" stuff. You'd need to do a lot better than that to convince anyone.

    A pair of Huxleys for breakfast anyone?

    "Facts do not cease to exist because they are ignored." Aldous Huxley

    " Science is organized common sense where many a beautiful theory was killed by an ugly fact". Thomas Huxley

    Behe's ideas are just that, ideas. After having had a run-in from a grade 10 science teacher who was trying to push Behe's ideas as an alternative, I read Creationism's Trojan Horse: The Wedge of Intelligent Design, which suggests that the ideas are promoted to at least a degree, as a shifted strategy when frank and direct creationism no longer was possible to promote directly. That it is about ideology, not science, and they see it as a war. In war propaganda may be less important than truth. Perhaps slightly over-stated at times, but certainly helps to understand when those promoting an ideology hold so tightly to repetitive argument.

    It's the same in history too, pseudohistorians wanting to prove that the Holy grail was hidden in Rosslyn Chapel by the Knights Templar do the exact same thing, so do holocaust deniers - the key is in the term 'denier'.

    Modern creationists are really evolution deniers - because there's a ton of evidence and academic research from top-notch academic sources which they have to deny to maintain their view of things. They deny whatever doesn't fit with their theory. As they get desperate they end up also having to deny the integrity of almost the entire (relevant) academic profession all over the world.

    This level of denial is something which professionals in these fields find absolutely gobsmacking. Sometimes it's the case that the deniers are so amazingly ignorant that they themselves don't need to deny very much - as they know bugger all about medieval history, biology, maths or whatever discipline is at stake, but very often they depend on people who, theoretically, really ought to know better and who have despite that, chosen denialism.

    So they desperately latch onto any supporters of their cause with any academic credentials, but because they're not themselves knowledgeable, they're not very good at evaluating these types and why they have chosen denialism. The denialist fans like to cast their Pet Professors as Galileo versus the Inquisition. In fact most of them fit a couple of common profiles:


    Point any of these out, of course, and their adoring fans will scream blue murder about ad hominem, but the thing is that other researchers in the field have already established that Pet Professor is talking a pile of old toss contradicted by the evidence, we're simply wondering at this stage what possessed him/her to go and do it.

    Of course what they'd like their Pet Academic to be is Galileo Prof but amazingly their chaps/chapesses are usually clinging to some old and discredited theory and never seem to find any experimental evidence to back them up or to make predictions which work. Funny that.

    But anyway, playing Spot-the-Denialist is always a good bit of fun.

    Jamat. With all due respect, the idea that chance is the arbiter of the outcomes rather than something that helps generate that which is tested is a complete straw man. Chance is not and has never been the arbiter. Does something survive and reproduce? That is the arbiter. And that isn't a matter for pure chance.

    If that's what you mean by chance being the arbiter of outcomes, then his book is about as relevant as one about the possibility of ships made of iron that dismisses the possibility because it makes the asumption that the ships are made of solid iron. It might be true. But it's not relevant to anything and to claim it "wins the argument" simply misses what the argument is. It is wholly and completely irrelevant to the argument.

    You can claim he wins the argument all you like. But that reflects more on you and your understanding than the argument itself. Either he is wrong (the mathematical argument) or he is irrelevant (the chance being the arbiter argument).

    And if you want to know about probabilities and why looking at an event after it has happened and claiming its probability is unlikely is completely mathematically spurious, try shuffling a double pack of cards. After you have shuffled, assuming a fair shuffle, the probability that the cards are in that specific order is around 1 in 10^150. Unless you predict in advance what the order will be, the fact that it is unlikely that it happened that way is utterly meaningless. It had to happen some way and all ways are equally unlikely. Which means that something horribly improbable has to happen.

    I don't understand what you mean here. Can you explain? It doesn't make sense.

    We have got a very good idea about ordinary life processes such as reproduction, growth, feeding, death and so on. Those are the kind of things we are talking about here, not any weird mystical philosophical stuff. There is no neccessary concept of "it had to happen that way" in evolutionary biology - quite the opposite, what we are saying is "it happened like this".

    quote:

    This begs the central issue of accounting for the thing's existence.

    That's a different question from the fact of evolution. I don't think any biologist anywhere is claiming that they know for certain how life came into existence. Lots of them think that its a question that can be studied by science, and many of them think they have plausible ideas that might turn out to be true.

    quote:

    The idea in between the lines of course is that what happened had to occur through existing natural processes

    That's not "between the lines" that's explicit and its the fundamental idea behind studying things scientifically in the first place. That's what science IS. If you did not believe that something was a natural process, if you thought it was some sort of intervention into the universe from outside and not subject to the natural processes we see at work in the universe, then you could not study it scientifically.

    quote:

    ...the other idea is that neo Darwinian theory is adequate to account for what we see, for that final 'black box' the cell.

    What do you mean by "final 'black box'"? The word usually means something that we can't see inside of. We have lots of knowledge about what happens inside of cells.

    And yes I'm pretty sure that natural processes such as reproducction, inheritance, selection, genetics and so on can describe how the first living things evolved into the first cells, and how those cells evolved into us and the other life we have around us. If that's what you mean by "neo Darwinian theory" then you are wrong.

    quote:

    Behe says it isn't. He is right.

    But why do you think that? You've not explained what it is about what he writes that makes you want to agree with it, just asserted that you think he is right. Plenty of people have pointed out why he is wroing but you haven't yet engaged in any real discussion with them, just repeated your assertion.

    That just shows your ignorance of certain hypotheses. That there are ideal kinds of animals and they merely reflect the platonic ideal. That things are genuinely random. Cloning. And there is a hell of a lot of luck involved in natural selection.

    Survival of the fittest and common descent is not circular. It merely seems so to you because there are no other challengers that have lasted.

    Oh, you want to talk about abiogenesis. That's a different field. And has about as much to do with evolution as stellar formation has to do with geology. Now stop trying to change the ground rules.

    You know what? There are predictions made of what we will discover with modern biology before we discover them. DNA was discovered with significant help from guessing it was more or less the same in all creatures.

    Or are you trying to drag abiogenesis into this argument again?

    quote:
    Behe says it isn't. He is right.
    Behe's evidence and claims when tested all come down on the Darwinian side. It is possible he is right. But only on the same grounds that a stopped clock is. As things stand plenty of evidence has been presented that whenever testable, what Behe says is either in line with contemporary biology or wrong. You know Behe is wrong on just about every point of fact that's been tested. So why are you lashing yourself to the mast of a sinking ship?

    quote:
    And Louise, the time honoured device of mocking those who disagree is not only dishonest it is pathetic.
    Almost as old and pathetic as the tactic of jamming your fingers in your ears at any contrary evidence, sticking to your guns despite it being pointed out that your arguments are threadbare, and taking any authority you can find. At that point the temptation to mock is almost overwhelming because you have demonstrated that you are both incapable of constructive debate and unwilling to put the work in to actually have a clue what you are talking about.

    "... blinding me with Science which admittedly is not difficult." Then why the fuck don't you admit that you do not have a clue what you are talking about and aren't willing to take the time to understand it. At that point, why put fingers to keyboard?

    Romans Ch 1 says it all.

    I'd no idea that St Paul was fond of Holocaust Deniers, people who claim Jesus married Mary Magdalene and ran off to the South of France, ambitious history professors who claim to have consulted archival sources that don't exist, (and who when asked to show their notes claim they were all mysteriously destroyed in a flood), people who carried out unnecessary and painful tests for financial gain on children with autism (to flog their own proprietary single vaccine), racial supremacists who use pseudo-archaeology to show their culture is superior, racial supremacists who misuse statistics, people who cook up UFO theories to sell books...

    I see the outliers a lot because they get a lot of media attention outside academia.

    Pseudoscience and pseudohistory - denialism if you want a blanket heading for it - are real problems. When applied to subjects like vaccines, and master race theories they kill people. The academic standards which expose the medical quacks like Andrew Wakefield and the Neo-nazis like David Irving, are the very same standards which you seem to want to miraculously go away and not apply where creationism/intelligent design is concerned because they produce answers you don't like.

    And yes, you can practically write a field guide to academic cranks, their psychology and the tactics they use, and no it's actually not very funny when you consider the damage that they do.

    The same few cranks get cited over and over again. Ctrl-F finds 454 references to Behe on this thread alone. His stuff has been debunked over and over again. Now it's got to the stage where his partisans don't even bother to try and defend him - they just assert that in the face of all or any evidence that they think he 'wins' or think 'he is right'. It's beyond parody.

    There is really no longer any point in trying to engage in scholarly terms. It's clear you don't deal in that.

    So we're left with the meta-questions, why in the face of repeated rational disproof and evidence do people insist on parroting that 'X wins' or 'X is right' when it's clear that X does no such thing? How do we deal with denialism? Why is it that the Grail fancier, the neo nazi, the creationist and the anti-vax campaigner, though completely different in the subject of their enthusiasm, do pursue surprisingly similar tactics? Can we learn something from it?

    What is it that turns someone into a denialist-type academic? What do they get out of it? Can we help people to recognise them better and to understand that not everybody with credentials is doing good work? Why do people faced with 999,999 honest academics doing good work, go crazy for the one fraud, quack or showman in their discipline?


    Is it actually more of a media problem? That the media loves man bites dog/ Black swan type stories?

    Is it an education problem? That we're not teaching critical thinking well enough?


    Is it something in human psychology (it cant just be religion as the problem goes beyond issues of religious belief) which makes some people cling to a belief in the face of all external evidence?

    It's something we need to understand soon, because the climate change deniers could end up killing us all, by voting for disastrous policies. There are enough of them in countries like the US where it really matters.

    Maybe we need a separate thread for people who were creationists to explain what got them into it and what got them out of it.

    I'm not laughing at you, Jamat, I'm holding my head in horror at the damage these dishonest or crazy or obsessed academics do and rolling my eyes at the way I see the same types turn up over and over. Maybe you should try as an exercise looking at a field where you reject the denialist position, and look at how they work, the tactics they use and what sort of authorities they try to co-opt.

    Holocaust denial/ anti-vaccination are non religious ones which are worth studying.

    Actually his Bad Science blog and the very wonderful Language Log blog do a very good job of debunking some of the crap that is said about science. Unfortunately it gets everywhere - the BBC is particularly bad (their science programs are often brilliant but their general news reporting of science includes heaps of rubbish)

    It's a symptom of journalism everywhere, Ken. Thanks to cost-cutting, you have non-subject specialists covering things they know nothing about, and they have no time to check with people who do know what they're talking about, or to look things up, so basically you just see a lot of recycled press releases, especially on websites.

    You should see how bad a lot of history reporting is across the board. Scientists have little idea how bad most of the humanities reporting is and vice versa. I got a rude awakening when I helped with a few science programmes, and discovered that most newspaper reporting of science is not fit to line a budgie's cage, even from so-called quality newspapers. It did however turn me onto more places to find science papers and where to find subject specialists blogging in some fields. But most people don't bother.

    Bad Science by Ben Goldacre. It's written by a doctor rather than a journalist and pretty much sticks to its topics rather than being a "get off my lawn" rant. Chunks of it are Britain-specific (at least I don't think Gillian McKeith had much presence in America?) and it only handles scientific issues, even missing global warming denialism. But it's as good a book as I can think of.

    Wheen on the other hand appears to be writing a "Get off my lawn" rant. Entertaining in places, correct in places.

    Its a fucking brilliant book. Ought to be part of the school curriculum. And compulsory reading for all journalists. I've bought it twice - when I lost my first copy I got another.

    But it is about fake medical crap, not stuff like global warming denialism, young-earth-creation, or similar flat-earthery. And certainly nothing about Holocaust denialism, which is really a political strategy, not an argument about evidence.

    Ben Goldacre's Bad Science blog is worth keeping up with. Along with the lovely Language Log its one of the nodal points on the online fightback against pseudo-scientific handwaving bollocks. [Smile]

    I think this is the hidden assumption which Nobel Prize-winning physicist Brian Josephson (Cambridge) pointed out in a letter to the Independent (Jan 12 1997). 'In books such as the Blind Watchmaker, a crucial part of the argument concerns whether there exists a continuous path, leading from the origins of life to man, each step of which is both favoured by natural selection, and small enough to have happened by chance. It appears to be presented as a matter of logical necessity that such a path exists, but actually there is no such logical necessity; rather, commonly made assumptions in evolution require the existence of such a path."

    I think he's confusing two senses in which something can be said to be necessary. There is logical necessity. As G.K.Chesterton puts it in The Ethics of Elfland,
    'For instance, if the Ugly Sisters are older than Cinderella, it is (in an ironic and awful sense) necessary that Cinderella is younger than the Ugly Sisters. There is no getting out of it. Haeckel can talk as much fatalism about that fact as he pleases: it really must be. If Jack is the son of a miller, a miller is the father of Jack. Cold reason decrees it from her awful throne: and we in fairyland submit.'
    In that sense, it is necessary that if humans evolved from the origins of life, there exists a continuous path. But that doesn't mean that it was a necessary fact that humans would evolve.
    It wasn't necessary that a path existed from the origins of life to humans; the only necessity is that given we know that humans did evolve there must have been a path.
    (Whether the path exists necessarily is another question: Dawkins, from the atheist end, and Conway Morris, from the Christian end, both seem to agree that given the existence of life something like humans is inevitable, while Jay Gould thought that it isn't.)

    A path as such may well exist. Convergent evolution suggests that the similar physical and environmental factors determine the morphology of widely distant species.

    Basically put, why do sharks and dolphins share many of the same morphological characteristics, despite one being a fish and the other a mammal? And to a lesser extent, penguins, even though that's a bird?

    Because they have to hunt the same prey in the same medium. Fluid dynamics determines the shape, the type of prey determines mouth and eye location.

    I know one of the leading exponents of convergence (Simon Conway Morris) postulates that a bipedal, upright creature with colour binocular vision and the ability to run long distances without tiring (I know, I know, look at most of us now...) were inevitable as alpha predators on the plains of Africa.

    Thanks for this (and to you Dafyd). I'd not come across Conway Morris. As I understand it, 'convergence' is an alternative explanation for similarities in species without reference to a common ancestor. Morris (if I understand him correctly) would put the inevitability of man down to a designing hand.

    @Dafyd - yes, I think the point of the quote was to argue that the evolutionary process does not necessarily lead to the evolution of homo sapiens. We could run the process again and get different results.

    I'm thinking my way through this undesigned/guided design question at the moment so will be posting some more thoughts for comment. Any input, gratefully received.

    It's a subtle difference, perhaps, but an iterative minimum is not the same as active design.

    OK - let's have another go at understanding Conway Morris.

    Simon Conway Morris (Cambridge University) is, so I'm given to understand, part of a growing circle of popular science writers, (inc Paul Davies, Stuart Kauffman, and Michael Denton), who accept evolution but reject that it is haphazard and that, as the late Stephen Jay Gould put it, if we re-ran evolution, we may well get different creatures evolving.

    Conway Morris argues that (although he accepts all life had a common ancestor) not every feature of biological similarity can be attributed to *descent* from a common evolutionary ancestor (the usual Darwinian position). Certain evolutionary features appear in creatures with different ancestors, which means these features must have been reinvented in the natural order multiple times. This is biological 'convergence.' Conway Morris documents numerous examples in a five-page, double-columned index of his book Life’s Solution: Inevitable Humans in a Lonely Universe (Cambridge: Cambridge University Press, 2003).

    One of the best known examples of convergence is the evolution of the camera-eye in vertebrates (humans) and cephalopods (octopus/ squid). These eyes are both highly complex and almost identical in every respect (the only obvious difference is the neural wiring— backwards in vertebrates with the nuclear layer being in front of the retina, which results in a blind spot). Since, according to evolutionary theory, humans and octopuses had separate evolutionary precursors of which neither possessed eyes at all we have to conclude that in the evolution of humans and squids, evolution required the reinvention of virtually identical camera-eyes 'from scratch' twice. And as Conway Morris shows in his book this is not only remarkable, but also the norm in the natural order.

    For Conway Morris, biological convergence provides clear and decisive evidence that evolution is limited in its possible trajectories and is therefore not haphazard. On the face of it, this appears similar to the views of adaptionists who are happy to see the reinvention of certain structures as 'inevitable' in that they are simply the result of the best adaption
    possible given the circumstances.

    But there is a deeper disagreement. Neo-Dawinians take the view that evolution could take adaptations in any direction, and the results we find today are just the results of the best ones. Conway Morris disagrees. For him the trajectories in which evolution could go are actually quite tightly defined. The definitions are constrained by - as yet undiscovered - natural laws. As a theist he sees these laws entirely congruent with the view of a creator God. Whilst not a proof for God, he sees it as perfectly consistent with theism to say that these laws are built into the created order by God.

    That's not to make Conway Morris a creationist. He rejects both creationism and intelligent design (although ID proponents complain that he misrepresents their position). So to take the example of the evolution of mankind, he sees this as the inevitable result of a process through which God intended humanity to be the pinacle of natural order. But this is not the result of special creation, or a guiding hand at work throughout the evolutionary process, but the result of these as yet undiscovered natural laws.

    Ramarius - that's a reasonably fair summary, though his position is highly nuanced (I have corresponded with him, but not actually met him in person. He's an SF fan, too).

    I think he's right about the inevitability of some structures and morphology. Reinventing the eye across many different classes is the obvious example, in that spotting your prey/predator is such an evolutionary advantage that higher order animals are almost always going to have some sort of light-detecting organ, even if they augment it with other senses.

    Our - humans - inevitability is still controlled by wild chance. Initially, one famine, one disease, one volcano, could have taken Homo Sapiens Sapiens out. Morris is suggesting that something like us was inevitable. That SF staple of lizardmen is just as likely. Most dinosaurs weren't very big, occupied many different niches, ate a wide variety of food, etc. We could be them, postulating that if we'd have been hit by that massive asteroid instead of it making a really close approach, those funny rat-like mammals might have come to dominate the biosphere.

    As does Lenski's work with long-term bacterial evolution. [Official website] In essence Lenski has devised an experiment where he can "re-run" evolution and he does get different results when he does so. The ability to freeze and preserve previous generations is one of the advantages of working with bacteria.

    Thanks for the link to Lenski (I'll try and find some reviews - any you can recommend?). Lenski would then support Gould's punctuated equilibrium. What do adaptionists (like Dawkins) make of it?
     
    Posted by Pre-cambrian (# 2055) on :
     
    Not necessarily. The arguments between punctuated equilibrium and phyletic gradualism are basically about the speed and temporal regularity at which evolutionary change takes place. That's a different question to whether the results of evolutionary change, when it happens, are haphazard.

    Then you'd be wrong. Why, what would you expect to see?

    We all - as far as we can tell - carry mutations unique to us that are not inherited from either parent. Some are lethal, some are benign, most are unexpressed. A very, very few are advantageous.

    The genomes of every living creature are altering with every generation. As it has been since C, G, A and T first met up.
     
    Posted by Pre-cambrian (# 2055) on :
     
    No, I'm afraid Dafyd is right. Something that is transitional is in a position between, say, point A and point C. A dinosaur egg, or anything that gets eaten before it can breed, is a genetic dead-end and by definition cannot be transitional to anywhere.

    It was a trick question (well, statement).
     
    Posted by Doc Tor (# 9748) on :
     
    Again, no.

    Nothing is fixed. Points A and C don't exist except in relation to Z and D.

    If you're being pedantic and insisting that the individual egg, because it's fossilised before it hatches isn't in transition, then okay. But it represents transition in the same way that everything other fossil does.

    What I'm trying to get over is the point that when Creationists witter on about the lack of transitional fossils, they're missing how evolution works (well, duh).

    Species are not static, even during equilibrium conditions.
     
    Posted by Dafyd (# 5549) on :
     
    Yes. There aren't any fixed types in nature for fossils to be in transition between. But, really, the word 'transitional' is itself a sign of a misunderstanding - if you're doing actual palaeontology you don't use the word or concept. You only need to use the word to refute creationists who think there aren't such things.

    Is the discussion between the puncs and grads roughly this?

    Gould suggested that sometimes mutations happen that have no immediate benefit; but that they nonetheless remain in the gene pool because they are not harmful. They remain in the gene pool and may subsequently become part of a later beneficial mutation. This is "Historical contingency” which simply means, “it depends upon something that happened in the past.”

    Gould’s opponents say that the *environment* drives evolution to a particular solution, (so it doesn’t depend on past changes paddling away lazily in the gene pool) and that a mutation conferring no immediate benefit will probably disappear from the gene pool before it is eventually "needed."

    No. There's no one working in the life sciences today who doesn't accept the reality of neutral mutations. You're conflating questions of gradualism (slow, incremental changes over time) vs. punctuated equilibrium (rapid changes over short periods of time followed by long periods of relative stability) with the question of how deterministic a given environment is towards a few, very specific solutions. These are separate, and only marginally related, questions.

    To go back to the Lenski experiment, we see that certain evolutionary solutions are adopted by all strains (larger cell volumes, lower maximum population, specialized glucose metabolism). This seems to be consistent with both gradualism and environmental determinism and probably represents the mutational "low hanging fruit".

    On the other hand, the true breakthrough in adaptation (the ability to metabolize citrate) is consistent with both punctuated equilibrium (once Cit+ evolved, it rapidly took over population Ara-3) and contingency (no other strain developed Cit+, Ara-3 ancestor strains could also evolve Cit+, but only if taken from generation 20,000 or later).

    At any rate, going back to the question of human-level intelligence, it seems to me to be more akin to developing Cit+ (a very rare series of contingent mutations) than to the "low hanging fruit" mentioned above (which would probably include things like certain coloration patterns or refractive lens eyes). Given about four and a half billion years of life (and about six hundred million years of complex multicellular life) only one known species (us) has managed the trick, compared with a lot of convergently evolved eyes, wings, camoflage, etc.

    Yes and no. I think you've roughly characterised one area in which Gould disagreed with other evolutionart theorists. But it's not the area of punc vs grad.

    Punctuated evolution means that evolutionary changes tends to happen fast in bursts, in response to fast changes in the environment, and then settle down to stretches of nothing much happening (because all the organisms in an ecosystem are pretty much as well adapted to the environment and each other as they can be). Gradualism is the belief that evolutionary change ticks over slowly and steadily with no sudden bursts.
    It so happens that Gould and Lewontin, who proposed punctuated equilibrium as the most widely applicable model of evolution, are also well-known proponents of other semi-controversial positions. But that doesn't mean that there is a necessary connection between all those debates.

    Actually it's very old creationist bullshit. I can't say what's kicked off the recent spate of "evolution is on its last legs" that you've come across, but creationists have been predicting the imminent collapse of Darwinian evolution (and before that, geology) for literally centuries now.

    OK, its obviously not true, but what do they back themselves up with when challenged?

    In my experience they pull in three kinds of support for this contention about evolution (I can't talk about the cosmology)

    1) they quote stuff from a small number of rather clever physicists or mathematicians or philosophers who simply don't understand modern biology (i.e. post-Darwin) and bring up absurd objections to the idea of evolution. The best known of these is perhaps the late Fred Hoyle, who was a cosmic super-genius of the first order, and a hero, and ought to have got the Nobel Prize, and was a pretty decent SF writer too, but who knew fuck all about biology. Others have had similar failures. The root cause of their misunderstanding seems to me to be a sort of philosophical essentialism, which maybe helps with physics and other such sciences but misses the point entirely in biology. (Well, not just me so much as me channeling Ernst Mayr...)

    2) they quote stuff from the so-called "Eclipse of Darwinism" period, when a large number of biologists accepted the fact of evolution and the great age of the Earth but rejected natural selection as a main driver of evolution, and some of the main consequences of that. Again it kicked off with essentialism, and a big dose of what the Germans called "Naturphilosophie". It was reinforced later by widley held misunderstandings about the supposed incompatibility of Mendelian genetics and Natural Selection leading to odd ideas about saltationism and some handwaving stuff about life-forces and essences.

    This was common from maybe the 1870s to about the 1920s, with a considerable long hangover from it going up to the 1940s or even 1950s, especially among German-speaking biologists, and among botanists. That period was brought to a close by the so-called "New Synthesis" which explained, pretty clearly, how population genetics, natural selection, speciation, and phylogeny did all fit together. After the 1920s pretty much all English-speaking and Russian-speaking biologists were Darwinians again (though the Russians got kicked back by Stalin later) and most continental Europeans got on board by the 1940s.


    The "eclipse" coincided with the rise of YEC in America, so lots of the early YECcies quoted anti-Darwinian biologists from the 1900s in their books. And the quotes got transmitted from YEC to YEC, even if their originators had long been disproived, or changed their own minds.


    3) Some polemical YECs are in the habit of taking disputes between biologists about the nature or course of evolution and treating them as casting doubt on the fact of evolution. They have had great fun with the punctuation vs. gradualism thing, with pattern cladism, with the recent re-recognition by some biologists of some place for group selection or saltation, with the argumetns abotu so-called "selfish genes". What they don't admit is that all these are disputes within the broad world-view of the neo Darwinisist synthesis and that (almost) none of the participants actually disbelieve in tghe great age of the earth or in the fact that new species originate through natural selction.
     
    Posted by Ramarius (# 16551) on :
     
    Looking at some reviews of the Lenski experiment I've been surprised at just how limited the experiment has been (hardly a re-run of evolution). For example, no new metabolic function evolved - the ability to digest citrate was already there. What was lacking was the ability to * transport* the citrate from the outside environment through the cell membrane into the interior.
    As Lenski himself puts it in his ipaper “The only known barrier to aerobic growth on citrate is its inability to transport citrate under oxic conditions” (para 5). And getting e-Coli to use the citrate was a pretty tortuous process. Lenski again '..none of the 12 LTEE populations evolved the capacity to use the citrate that was present in their environment for over 30,000 generations. During that time, each population experienced billions of mutations (22), far more than the number of possible point mutations in the _4.6-million-bp genome. This ratio implies, to a first approximation, that each population tried every typical one-step mutation many times. It must be difficult, therefore, to evolve the Cit_ phenotype, despite the ecological opportunity'

    So  after over 20years of selective pressure over some 360,000 generations ( 12 x 30,000) has produced a minor novel trait. The experiment shows a change at micro level only (no macro evolutionary changes) and is hardly representative of a natural environment (no dead cells to scavenge, no contaminant, no other bacteria involved). Hardly surprising that both Conway Morris and Behe cite the results to support their own divergent views on evolution.

    Basically we get the results we get because an intelligent agent created specific conditions and ensured they were maintained without contamination (no random influences allowed to interfere) until certain results pertained.

    Its quite possible that no completely new significant metabolic pathways have evolved for a few hundred million years. Not since green plants developed lignin and some ways of building complex stuctures with phenols and other aromatic compounds, and one major group of fungi evolved ways to eat them. Sometime before that animals learned a few clever tricks with steroids. Thats about all there is that bacteria can't do, and the things that bacteria can do they swap betweem themselves in ways that we mostly don't. So what's the chance of getting a new one in only a few years? Think of the scale!

    Of course. Think if the scale! If even such a tiny experiment as this can do all that, what could happen in the wild, with much larger numbers, much more diverse genomes, and other bacteria to swap genes with, the chance of larger mutations or of two mutations coming together, is much greater.

    Which is bloody amazing! If evolution worked that fast in the wild - well, it would be staggering.

    Think of the scale.

    The bacteria we have now might have had about about two billion years to develoip the range of metabolic capabilities that they had when the first prokaryotes evolved - no-one really knows because its impossible to tell from fossils exactly when the earlier organisms had settled down into what is now the standard pattern , and almost as hard to tell when things other than bacteria evolved. But lets estimate two billion. So that is one hundred million times longer than the experiment - 10^8 times more time.

    No-one knows how many bacteria there are in the world. Estimates vary from maybe a tenth of thge biomass of the whole planet to almost all of it. No-one knows for sure what the biomass of the planet is. Also no-one knows how much of it is dormant and how much actively growing (the latter obviously more likely to both mutate and be selected) Also things work very different on land (where organisms tend to hang around for a long time and build complex structures) in the seas (where turnover and primary production is higher than biomass) and in sediments and under the surface (where most life is probably dormant much of the time - but this is the great unknown of mega-scale ecology)

    A conservative estimate for biomass might be a trillion tonnes, 10^15 kilos - so guess 10^15 times the size of the experiment.

    But the genetic diversity of the world is very great compared to the experiment. No-one knows how many broadly distinct baterial species there are - in fact the question ins probably meaningless because bacteria don't form distinct species in the way we do, their whole population genetics is qute different. There are less than ten thousand known to traditional microbiology, some researches estimate there might be a trillion different bacterial species (according to some dodgy definitions). What really counts is the number of differently organised genomes. Lets make a very conservative estimate of a million - much less than the probable number of different animal species! Thats 10^6

    So the size of the "experiment" that led to the bacterial world we have now is, at an extremely conservative estimate 10^8 * 10^15 * 10^6 times larger than the lab experiment. That's 10^29 times bigger.

    Its kind of hard to get over quite how big a number 10^29 is. But if it only takes one little experiment evolve a "minor novel trait", 10^29 times more than that is going to evolve an awful lot. I mean you thought space was big...

    In real life of course its even bigger an more complicated than that because the whole world is partitioned into vast mumbers of micro-climates and little envirtonments in which different things happen. And far more for bacteria than for us. Compared to a bacterium the body of a large animal (such as a human) is about the same size as a small planet like Vesta or the Moon or Mars is to us. Except that they don't just live on the surface of the "planet" they live all through it on all the internal structures and membranes - at the level even of organs such as lungs and livers and blood vessels thats's thousands of times bigger than the outer surface of the body and wehn you bring in cell membranes its vastly biuggger than that - so to bacteria each of us presents a living space as large and diverse as the whole Solar System would be to us if we could get there. Which is one reason each of us hosts trillions of bacteria with perhaps thousands of different kinds of genome organisation.

    Oh, and viruses... there are a loit of genes in viruses. And there are millions, perhaps billions of them in each cubic centimetre of seawater. And lots of other bits and pieces of genetic material floating about. Plasmids and weird stuff and things that look like dormant genomes of dead bacteria. All over the bloody place. And bacteria, or at lest some of them, go around grabbing hold of these things, taking DNA out of them, and trying it out to see what it does. (Really - do a Google search for "transformation competence"). So whenever anything new turns up in the way of genes, sooner or later it will be paired with pretty much everything else. So all those little mutations will have the chance to be combined into larger ones. Which is how bacterial genetics mostly works now and why its not driven by brand new genes so much as by the vast availablility of old ones. The infinite number of monkeys don't need to re-write the worlkd of Shakespeare because they are already living in the Library of Babel. And of course its why in real life we'd expect bacterial evolution to move faster than in the experiment because of the diversity of genetic material in any one environment, and because things are exported between environments.

    @ken. Thanks for the info above. As you may know from previous discussions on cosmology I'm fascinated by mind-boggling numbers...

    The issues Lenski's experiment raises are different though. You can have as much variation in the system as you like - the question is what it takes to enable those variations to combine to bring about beneficial adaptations. Two points on that. The first (and repeating what I said above) to get the e-Coli to a place where it could digest citrate,  necessitated that specific conditions prevail, and continue to prevail over an extended period of time. The implication of that is the more variables you introduce, the less likely you are to get a beneficial adaptation since there's more that can go wrong. 

    The second point reinforces that, since along with beneficial there were also a significant number (may turn out to be as many as half) mutations that were degretative - they eliminate a gene or its protein function.

    Put that together and the evidence from this experiment is it's incredibly difficult to create the conditions for a beneficial adaptation on the basis of our current understanding of the evolutionary process.

    And just to add to that, on the basis of Lenski's results to date, there's no indication that these changes are on the way to building a new *complex* system.

    Obviously the whole science of evolution won't be re-written on the basis of this experiment, but it's throwing up challenges to our understanding of evolutionary theory to which we need to give proper consideration.

    First off, how do you distinguish between "micro" and "macro" when dealing with organisms that are themselves microscopic? Bacteria don't really have a "macro" level. Similarly, what's the threshold for a "major" novel trait? Membrane permeability is a pretty major function as far as bacteria are concerned. And why do you ignore the several other novel traits that are indisputably minor (e.g. greater cell volume, optimized glucose metabolism)?

    Behe's response demonstrates about equal parts chutzpah and avoidance given that Lenski's work demonstrates that one of the cornerstones of Behe's position is incorrect. Here's the relevant section:

    quote:
    One of the major points of [my] book [The Edge of Evolution] was that if only one mutation is needed to confer some ability, then Darwinian evolution has little problem finding it. But if more than one is needed, the probability of getting all the right ones grows exponentially worse. "If two mutations have to occur before there is a net beneficial effect -- if an intermediate state is harmful, or less fit than the starting state -- then there is already a big evolutionary problem." And what if more than two are needed? The task quickly gets out of reach of random mutation.
    Lenski's work pretty clearly shows that the development of Cit+ is the result of at least two separate mutations, which is why the Ara-3 ancestral line can only re-evolve it using samples taken from generation 20,000 or later. There was some mutation there that didn't grant Cit+, but which was a necessary its development 10,000 generations later. In short, random mutation can do exactly what Behe claims it can't do.

    Yeah, it's what most scientists call "controlling outside variables". It's usually considered a strength, not a flaw. The whole point of the Lenski experiment was to see if random mutation working with selective pressure is sufficient to evolve new traits. As such great care was taken to eliminate outside sources of genetic material, going as far as making sure to use E. coli strains that don't engage in bacterial conjugation. And I'm not sure that the distinction between a man-made selective regime and a naturally occurring one. Do you have any evidence that bacteria change their mutation rates when they know scientists are watching?

    This misses the point entirely. Natural selection isn't aiming for a particular beneficial adapation. It is selecting for adaptations that happen to work well enough to get along in the particular situation a population of organisms happens to be in.

    So the more variation there is the more likely it is that something, or some combination of things, will happen to work. Overwhelmingly so. There is a combinatorial explosion.

    quote:

    The second point reinforces that, since along with beneficial there were also a significant number (may turn out to be as many as half) mutations that were degretative - they eliminate a gene or its protein function.

    So? Why is that relevant? I'd be surprised if it was anywhere near as few as half to be honest - the odds are more likely hundreds to one. But so what?

    quote:

    Put that together and the evidence from this experiment is it's incredibly difficult to create the conditions for a beneficial adaptation on the basis of our current understanding of the evolutionary process.

    The other way round. The evidence is that successful adaptations are incredibly likely. Just look at the numbers.

    Are you making the golf-ball and blade of grass mistake?

    A golfer hits a ball. It lands on a blade of grass. Just one blade of grass out of millions? What was the chance of that? It must have been very well aimed!

    Natural selection - at least for bacteria - is the equivalent of trillions of golfers shooting trillions of balls at more blades of grass than there are stars in the universe. And as long as one hits, it works.


    quote:

    And why would you expect to see that after only twenty years?

    Think of the scale again. There are some thousands of major metabolic pathways. They probably took two billion years for bacteria to evolve them. (As I said before there are a handful that evolved in plants or animals but most come from bacteria) The whole world is, as I said, vastly bigger than the experiment. So if the experiment was capable of evolving new metabolic machinery at the same rate as real life (& it won't be because its so much simpler) how likely is it that you would see one in a mere twenty years?

    @Croeses. The difference between micro and macro evolution is noghing to do witn size. Micro evolution refers to changes signin existing structures. This is what Darwin observed, and what Lenski is observing. Macro evolution refers to large-scale innovation, the coming into existence of new organs, structures, body-plans, of qualitatively new genetic material; for example, the evolution of multicellular from single cell structures - it thus involves a marked increase in complexity.

    You've misunderstood Behe's point on multiple adaptions but I'll come back to that since it raises a wider issue. Your last point completely misunderstands the issue. It's precisely because it's a controlled environment with variables removed that makes Lenski's experiments unlike nature. You simply wouldn't get this very precise environment in a natural context. It's not that the bacteria are behaving differently because someone is watching, more that without the scientists they would never get the chance to have fun in this playground in the first place.

    I don't think this makes sense. 'Large scale innovation' in biology is always a collection of small changes. Do you have a specific example in mind of a large-scale change that couldn't be the result of incremental smaller ones? (it may save everyone some time, if you're tempted to use something from Behe, if you google for the rebuttals first.)

    It's a standard
    definition. The idea that macroevolution is the result of multiple small steps is the Neo-Darwinian view, but there are others. See the article, particularly the views of Gould and others who suggest that you don't need a continuous succession of small steps to get a macroevolutionary change.

    You're assuming the development of the ability to metabolise a new compound is qualitatively less complex than growing a new organ. I'm not at all sure that's true.
    Organs like a heart or lungs seem to me fairly simple to develop from pre-existing structures. On the other hand, evolving the ability to metabolise a new compound without interfering with any of the other metabolic pathways that happen within the cell seems to me rather difficult. It's a bit like moving one square on an especially fiendish Rubik's cube without ever getting any side less than half full of one colour.

    Fair comment Louise. Part of what I'm hoping to get from this discussion is an idea of where, as a non-expert, I can find info that is both authoritative and comprehensible. Part of the problem with the micro/macro definitions is the inconsistent way they are used by scientists [Frown] . So how about the following definition from the following source:

    ''Macroevolution is at least evolution at or above the level of speciation, but it remains an open debate among scientists whether or not it is solely the end product of microevolutionary processes or there is some other set of processes that causes higher level trends and patterns."

    A chaoter of his major last writing on evolution that deals with Puncuated Equilibrium has been published as a separate book.

    Punctuated Equilibrium


    One review says it's fairly opaque
    to the layman but includes a useful appendix.

    quote:
    But all is not lost. Gould includes a 63-page Appendix that is very readable by the layman. The Appendix deals with the controversies aroused by punctuated equilibrium in the broader media and academic communities outside palaeontology. The "hijacking" of punctuated equilibrium by creationists to debunk Darwin is well-covered and very interesting. Thankfully, Gould explains where creationist views are ignorant, wrong or dishonest - often all three.

    I haven't read it but it is probably an accurate summary of what he was saying.

Its interesting, and like most of Gould's books its well-written if a bit anecdotal and rambling at times (makes a nice change from some over-formal science writing) Its huge, and expensive, and I'd be lying if I said it was an easy read, or that I've read and fully understood every point in it. I am, however, reasonably confident in saying that it doesn't challenge, and wasn't intended to challenge, the broad consensus of neo-Darwinian synthesis. Its a critique of many details of the consensus, and an attempt to promote a new view of it, but the basic ideas are the same.

    Academic arguments are often expressed in surprisingly strong language. And polemical books - and this is a polemical book - are likely to focus on the points of disagreement rather than the landscape of agreement. Just as with group selection and cladism and the "selfish gene" this is not something that YECcies and IDiots can take much support from.

    Ramarius' latest posts have reminded me of the need to have some understanding of basic scientific concepts underlying physics, chemistry, biology, etc. in order to discuss these topics properly. It doesn't matter so much with evolution, but there are lots of other important scientific isssues that have more direct impact e.g. it has become apparent that quite a few people have no clue how birth control pills work. [Eek!] It would be nice if people were making choices based on something more than book reviews, second-hand analyses, letters to the editor, websites selling supplements and all the other less-than-reliable sources out there. A high-school or undergraduate text can provide the basics. Furthermore, there are lots of issues where the "alternate" view is simply horseshit, and no, the issue is not accurately represented by presenting both points of view. Fire, air, earth and water are not a credible alternate view of the periodic table. OliviaG

    It is frustrating when you get those who say "I know the science of X is wrong" and then follow it up with an admission that they don't understand what that science is saying - worse yet, that they don't want to understand it. I've never worked out how to make any progress in those kinds of discussions.

    (whether any's made in any other kind of discussion is perhaps moot...)

    I've got to call "bullshit" on this one. There are plenty of other examples of such adaptations occurring outside controlled laboratory conditions, including cases where the resulting adaptation was both unintentional and undesired. There's no consistent reason in this context to distinguish between an artificially-produced selective environment and a naturally occuring one. The only difference in the lab is the ability to exclude extraneous factors.

    At this point introducing you to your source would be a good idea. Michael Behe has admitted under oath (at Kitzmiller vs Dover Area School District) that "there are no peer reviewed articles by anyone advocating for intelligent design supported by pertinent experiments or calculations which provide detailed rigorous accounts of how intelligent design of any biological system occurred". In order to class Intelligent Design as science he needed to redefine science such that Astrology is classed as a science.

    And claiming that your book has been peer reviewed when you have to admit under oath that it hasn't isn't the act of an honest man.

    (As for Behe on maths, his own maths make multiple mutations inevitable).

    Except as Creosus has pointed out, we've seen such happen in nature. He pointed out two - MRSA and nylon eating bacteria. The real world is a huge playground and there are far more niches to occupy when conditions are uncontrolled.

    Well, bacteria don't. There are plenty of single-celled eukaryotes that have quite complex body plans. But your point is of course correct and important.

    Not even as big as that. Just a small change. But the real point is surely that the population of bacteria is so large, and so varied, and has been around for so much time, that its more or less inevitable that loads of small changes accumulate to make large changes. As large as you want.

    There is no real distinction between "micro" and "macro" evolution for bacteria. One is just the other repeated a lot.

    I think we might be talking to crossed purposes here. Just to be clear, I'm not an ID advocate - I haven't looked into ID (although there's an interesting discussion on it upthread).

    The question I'm puzzling over with respect to adaptations is the degree of difficulty that needs to be overcome for an adaptation to occur. In our current bio system there are a massive number if factors that can contribute to stimulate adaptations. Ken gave the figures upthread

    A scientific experiment replicates a much simpler environment in which fewer factors can come into play, and the scientist can decide which ones he wants to introduce and exclude. So my point on that is that it's a misnomer to describe Lenski's work as evolution re-run. Clearly it's not. Let's learn what we can from it without over-egging its significance.

    What I've found helpful in the discussion is getting clearer on how Gould resolved his problems in understanding the fossil record (that's much clearer thanks especially to Daffyd) and the fascinating question raised by Conway Morris as to whether there are (in effect) a limited range of adaptations that can occur irrespective of the number of potential factors available.

    I'll do a bit more research and come back with some more questions. Basically, there's a range of issues being discussed in evolutionary biology and I'm trying to make sense of them. So unlike in Purg (where I generally have a view to defend) this forray into Dead Horse territory is purely exploratory.

    You are right in that the experiment doesn't re-run Evolution. It re-runs evolutionary pathways within tightly controlled conditions. That sort of model is the bread and butter of science. It gives this physicist hope that biologists might be scientists after all. Scientists design experiments and models to learn as much as possible about systems.

    Whether or not it's possible to properly understand a complex system such as an ecosystem by systematically investigating components in semi-isolation is an interesting philosophical question. My feeling is it's possible to gain understanding, but if you only think of the system at the level of individual components you fail to understand properly - you fail to see the wood for the trees; we need to understand both the trees and the entire wood (which includes a whole lot more than just trees).

    Bump.There's a very detailed discussion on the evolution of the eye which kicks off towards the foot of p.9. Here

    On the Non-Right-Wing Creationism thread, there was a conversational tangent about the irreducability of the eye which I was about to reply to when I noticed the hosts were ordering it to be redirected here. In case Mark Betts wants to continue the conversation on this thread, here is my reply:

    quote:

    To be helpful, here's a preview article from Scientific American explaining how scientists have been working on evolution of the eye and why it's a problem. They have been using embryo research across a range of species and DNA studies.

    quote:
    From the article:
    The results indicate that our kind of eye—the type common across vertebrates—took shape in less than 100 million years, evolving from a simple light sensor for circadian (daily) and seasonal rhythms around 600 million years ago to an optically and neurologically sophisticated organ by 500 million years ago.

    Can you really not see it? "This evolved from that, then something else evolved..."

    Do you really believe that this finally "puts the nail in the coffin" of the irreducable complexity argument? It doesn't even touch on irreducable complexity!

    So far you have been shown summaries of the theory of eye evolution, since the usual first argument that Creationists use is that it is theoretically impossible that the eye could have evolved, even if the theory of evolution was correct, since the theory cannot explain the irreducible complexity of the eye. The counter-argument scientists use is to prove that theoretically, it is perfectly possible for the eye to evolve, and explain the steps that woud be necessary for this.

    Yet this isn't enough for some creationists, they then change the goalposts to say that, okay the theory explains how an eye could have evolved, but you haven't proved that it did evolve. And therefore the explanation is just speculation (or faith) and thus quot et demonstrandum and nee-na nee-na (with appropriate gestures).

    So, here is one article arguing the case for the evidence that supports the theory of eye evolution. And here is a longer (but still quite brief) scientific summary of the larger quantity of evidence doing the same.

    From the second article:
    quote:
    ...all the observations are entirely consistent with predictions of [Darwin's] theory, as well as the computer modeling predictions indicating evolution of an eye by small increments in less than one million years. Rather than “intelligent design,” the structure of the oldest preserved fossil evidence for the vertebrate eye and brain shows the legacy of an ancestral segmented animal in the derivation and arrangement of nerves and muscles controlling eye movement, subdivision of the braincase, and other features. Despite the complexity, the organisation of the brain and eye ... illustrated here demonstrate a unique morphology, intermediate between living jawless and jawed vertebrates...Like ... many other vertebrate fossils elucidated since Darwin’s time, these are examples of the transitional forms that he predicted — they show combinations of characters that have never been observed together in living species.
    Now I admit, this isn't a real-time youtube video documenting the millions of years of evolution directly. So it won't convince you at all. But you have to admit, it's certainly more than just someone saying, 'this happened, then this happened'. This is someone saying, 'the evidence shows us that at Time A this was happening, then at Time B it had changed to this, and at Time C, it had further changed to this. Therefore this matches the predictions our theory made that the eye at Time A changed over generations into the eye at Time C'.

    I would add that there are an awful lot of things that are complicated. But, none of them, not one little thing, has been shown to be irreducibly complex. Plenty of things ID proponents have proposed as irreducibly complex, of course, but none that have stood up to someone with a wee bit of knowledge in the field coming along and showing how that mechanism could have arisen from several other mechanisms wiithout out the need for an external agency poking around.

    Speaking as someone who's recently lost a lot of my eyesight because of a fundamental design flaw in the eye - the optic nerve connects to the front of the retina, rather than the back - I'm unimpressed by anyone holding the system up as an example of something that had to have been designed.

    Whoever did it was either unaware of the octopus eye, which has the optic nerve connection behind the retina, or knocked it off as version 2.0.

    R

    (The problem is: the optic nerve has to come through a hole in the back of the eye and through the retina. If that hole is too small, as mine is, the blood supply in the optic nerve can get cut off and bad things happen.)

    Weirdly, some animals named as jellyfish such as the Portuguese man o' war (technically not a jelly fish)

    https://en.wikipedia.org/wiki/Portuguese_man_o%27_war

    have a polyp stage of life where individuals live as plankton, then conglomerate together to form what looks like a single animal to us, with some of the "polyp persons" becoming specialised as stinging cells or swimming cells etc.

    I also enjoy other conventional thinking-violating organisms such clown fish (think Nemo), the males of which turn into females if the female leaves her harem of males - the largest of which turns into a female usually. Headless male insects which continue to copulate after their mate eats their head is also food for thought, so to speak.

    Posted by Eliab (# 9153) on :
     
    I listened to it.

    Key points:

    ID isn’t religious. It’s a theory based on the same type of inferences that drive other scientific enquiries.

    ID doesn’t dispute that natural selection is a real process that produces biological change.

    Darwin is popularly believed to have solved the question of life, but natural selection doesn’t address the ‘origin of life’ question at all.

    In the past this wasn’t seen as a problem because it was assumed that the building blocks of life – cells – were basically simple, and their origin could be pre-supposed. Darwin answered the question of how increasing organisation and complexity could be generated.

    We now know that the cell is incredibly complicated. DNA replication in particular is far more complex than anything Darwin could have imagined.

    The only way we know that nature generates DNA is by replicating existing DNA. Current theories on how the process started are unconvincing. An “RNA world” with a subsequent DNA takeover is not a solution – an RNA world would be almost as complicated and its origins would be just as difficult to explain.

    DNA contains a great deal of information (a lot of the lecture was spent quantifying this in terms of information conceived as ‘reduction of uncertainty’, ‘probability’ and ‘specificity’, but I hope I do not do the lecturer an injustice by focussing on the staggeringly large amount of information as being his crucial point).

    The best scientific explanation is that phenomena should be explained if possible in terms of observable causes – the analogy was made to Lyell’s Principles of Geology: we explain landscape in terms of accretion and erosion over time, because we know that those processes occur and can in principle account for changes in the landscape.

    The best process we know of for generating and encoding information is conscious design.

    We cannot better account for DNA, or the information contained therein, by any other process.

    Therefore it is a valid inference, on the same basis of reasoning as science commonly employs, to conclude that DNA, and the information in the genetic code, was consciously designed.


    I hope that is a fair summary of the argument.

    It was a pretty convincing exposition of the argument “We cannot at present fully explain how DNA came to be except by postulating design”, but not, unless I missed the point, much of an argument for the much stronger proposition “We could not, in principle, ever explain how DNA came to be except by postulating design”. I associate the ID movement with arguments of the latter type – arguing not merely that we don’t know the way that natural processes could move from A to B, but that getting from A to B is actually impossible by natural processes.
     
    Posted by Karl: Liberal Backslider (# 76) on :
     
    Which sounds like a bait and switch - present "we can't currently explain this" when asked for "what cannot in principle be explained." [Biased]

    I'd dispute a few other points - the complexity of the individual cell has been long appreciated, but I suppose that depends on Meyer's timescale - the early microscopists who just saw boxes probably thought they were - and the whole point of RNA World is that it is less complex than DNA; RNA can catylise its own duplication, rather than the chicken and egg issue of DNA and its replication enzymes.

    As I understand it. I'm not an expert.

    I wouldn't accuse Meyer of a bait-and-switch on the evidence of the lecture alone. I thought it could be taken at face value as an argument for a more modest sort of claim than those I would generally associate with ID, so I'm inclined to take it that way unless there's some other reason to doubt his good faith.

    As a theist but not a creationist, the argument that DNA replication is so complex and improbable that we can only speculate as to how it may have got going, and can, perhaps, see the hand of God at work, is not one that I have any antipathy for. 'This could have been designed' seems to be to be a legitimate speculation about life's origins. So the more modest claims make sense to me as far as they go. I just wouldn't want to:

    a) employ it as an argument for the truth of theism. 'God' is a theory with explanatory power only if you are already persuaded that the existence of God is at least very plausible. If you aren't so persuaded (and many atheists aren't) then a naturalistic account, however uncertain, is always going to look more convincing;

    b) make it a ground of my own faith. DNA may be amazing and hard to account for, but if science does discover an full explanation for how it came during my lifetime, I want to find that discovery wonderful and exciting, not to regret it as finishing off something that helps me to believe.

    That depends on your definition of "detectable". For instance, it was a peculiar quirk of fate that put an oddball like Winston Churchill with all the right experience and skills in just the right place at just the right time. Not to mention George VI.

    To use Dawkin's analogy, how do you tell that a watchmaker has not taken the mechanism apart, cleaned it so that it works properly and then put it back together again? The answer is that - you can't - except that things work unexpectedly in a particular direction. The watch apparently (to everyone except the watchmaker) needs no repair.

    I once read someone put forward the idea that, a thousand years hence, people would claim that the history of WWII was clearly mythical, since the names of the leaders of the good side were obviously made up. Church Hill, Freeman of Rose Field (presumably referencing the Rosicrucian lot). Not sure if they included Joy Stone (Winston) in this hypothesis. De Gaulle is obviously the iconic Gaul, like Asterix. Whether Stalin was included, I don't know. Ironcutter (Eisenhower) would fit with the superhero metallic thing there. Then there's the Mount of the man of power (Montgomery). All coincidence?

    Which, of course, relates to our particular history. We look back and see Churchill just when and where he was needed to bring us to where we are now. If he hadn't been there, someone else would have taken on the role of leading the UK in 1939 after Chamberlain was clearly out of his depth. We would have a different history, we wouldn't have some memorable speeches but probably gained others. And, we'd be here looking back commenting on the peculiar quirk of fate that put [whoever] in the right place and time to lead the country.

    And, of course, the same applies to our own evolution. We look back and comment on some unlikely developments without which our evolution would have been different (how remarkable that a comet killed off the large dinosaurs allowing small mammals to occupy ecological vacancies). But, they're much less remarkable if we don't think that there's anything special about our particular history.

    This starts to head towards "not even wrong" territory.

    An unguided process can be shown to create, for example, bigger guppies, and more colourful ones.

    An "intelligent process" is also a something. If you are going to argue that things require intelligent causes, then you are going to require an intelligent process to create your intelligent process. If you start arguing mystically about "first causes" and so on, then you are revealing the religious roots of ID.

    The point about evolution is that you absolutely can test for it. You can make predictions - e.g. "if whales evolved from Group A then their proteins should show a greater similarity to those of existing members of group A than of group B" - test, confirm or disprove. As happens. All the time.

    Well, often you don't get any clear cut answers and morphological criteria or even different genetic criteria support different evolutionary trees. (Since you mentioned whales, according to wikipedia there's a shortage of proto-hippo fossils in a period where there ought to be some.)
    That's really only to be expected though - convergent evolution and long chain attraction mean that those kinds of predictions are going to come up with equivocal answers. It does however mean that these kinds of predictions don't count as falsifying tests for evolution, let alone Darwinian evolution.

    This doesn't make 'we don't know how it was done so we think it was designed' any better as an argument. I think as put it's pretty close to a No True Scotsman.
    Evolution can't come up with any true explanation for feature X.
    Here's an explantion of feature X by evolution.
    Evolution can't come up with an explanation, so that must be No True explanation.

    The theory of evolution as currently understood does not have an explanation for the origin of the first replicating organism. So, in that sense you are correct. Though, it's not clear what would be that first replicating organism - the cell with DNA and proteins is almost certainly a few million (or more) generations of replication down the line from that first organism.

    However, scientists have a variety of ideas of how that first self-replicating organism could have appeared. When, if, science understands the necessary processes to the point where there is a highly likely process that is understood and tested by which some form of self-replicating assembly of chemicals can develop from something else, would it seem so out of place to extend the understanding of evolution to include that first step of the development of life as we know it?

    First off, I'm not sure about the Virgin Birth. It isn't central to my faith, I'm agnostic on the subject.

    The Resurrection, on the other hand, is a fundamental part of the faith. What is more, there is evidence that something extraordinary happened on that first Easter morning; those early disciples experienced something that they interpreted as meeting the risen Christ, an experience so powerful that they suffered often brutal deaths for their faith. The faith of those first disciples is something that needs an explanation.

    And, an additional general point about miracles. I don't think miracles just happen to entertain us, they have a purpose and that purpose is to act as signs.

    So, we come to the origin of life. Is God acting in a supernatural way at this point central to the faith? No. That God created the heavens and the earth is fairly central, but the process by which He works is entirely different. Does God creating life by supernatural processes act as some sort of sign? Not really, in part because it would be a sign no-one actually saw. Is there compelling evidence that God chose to act supernaturally at this point, but then act through natural processes the rest of the time? No, none at all.

    That was the long answer. If you want the short response, I don't need a super-naturalistic explanation for the origin of life.

    If you look at the 10 mins from 50-60. Towards the 59min of the lecture he points out that the chemistry in the cell is separate to the information sequencing. He illustrates by the analogy of the magnetic board. The point is that self organising is a problem.

    Mmm - isn't this because mitochondria and chloroplasts have bacterial DNA and the endosymbiotic theory is that they were originally bacteria that became embedded in cells. (That link looks a bit like cell genetics 101). It is also called symbiogenesis.

    So supernatural guidance is obvious in the last minute?

    One can unequivocally see only the hand of God in the chemistry in the cell being separate to the information sequencing?

    Information sequencing is not due to chemistry?

    Careful how you answer. I'm still one of those who believes that the immediate origins of stuff and life and mind are supernatural. But it won't take much nonsense, like you need a willy to be a priest, to turn me in to a Christian materialist.

    The whole shebang (life, evolution, universe and everything) must never provide evidence for the existence of God* or there is no freedom to believe or not believe. Proof means there is not faith.

    Additionally, I should say that faith is overrated. I pretend** to be Christian for far more selfish and immediate reasons. It pleases my aesthetic sense to go to church where people are at least trying to be kind and selfless at least in theory. It helps and has helped me with some pretty awful anxieties from horrid life experiences. It provides me some comfort and amusement. I am professionally trained in science to the level of PhD; I see nothing within the ID arguments that tells me it is anything but a slight of hand so as to slip a "just so" religious argument into places it does not belong. If ever ID was proved true, I would cease to believe anything about God immediately.


    *or do I go by the bizarre nickname Intelligent Designer?

    **is faith required, or may I subject my scepticism to the divine care within the "mystery of faith" and contentedly leave it there while I ponder more important things like the sequence of notes in a cantata, series of comfortable words, or the genius of liturgy? All of which draws me much closer to Presence than kitchen table science.

    I firmly believe in the virgin birth and resurrection, and find that statement worrying.

    What matters, surely, is what's true, not what sort of explanation we think we need? You seem very close to saying that if someone believes in God (or at least, in a supernatural, active, miracle-capable God), they don't need to bother about science or understanding, but can, and should, be content to say "God did it" as an explanation for anything science can't currently explain.

    That attitude is obviously a dangerous one to hold from the scientific perspective - I think it's also dangerous from a faith perspective. Firstly because it makes scientific ignorance a ground of faith, a ground which will, inevitably, be eroded, and secondly becuase it locates the activity of God solely in the 'supernatural' realm. I believe in miracles - but if there is a God, the naturalistic stuff is his work as well, just in a less spectacular mode.

    If God made life through a scientifically discoverable process, that is wonderful, and would be interesting. He could have made life spontaneously and fully-formed by an undeniably supernatural miracle, of course, but I don't need him to have done so to be a believer.

    Martin will no doubt speak for himself but I expect he will say that God is totally constrained and not at all, the former by his imposition of free will on us and the latter by our inability to grasp it

    The Bible, suggests that God has completed the creation and is now upholding all things by the word of his power. We are promised that he will create again , a new heaven and a new earth are indicated in Scripture.

    With regard to constraints of action on himself, they are moral. His own character is truth so that should he say something, he must abide by it to be true to his integrity. Consequently, scripture and of course the devil can predict his actions so we have the determined effort of Satan to wipe out the Jewish race as the second coming of Jesus requires their existence.

    Simple Alan. Quantum mechanics. If one is in the material creation business (for a start: what are the physics of Heaven?) one HAS to comply with, work with the inescapable, absolute logic which predicates the laws of physics. One can overrule them with miracles of course, perhaps in the creation of life, definitely in the incarnation (and Mother Mary's witness is good enough for me).

    One can imagine, for the sake of a narrative, a story, that God envisaged the end - transcendent creation - and worked backward to the dimensionless constants necessary to achieve that in one Divine Planck tick at most or whatever process was necessary in infinite mind (question= answer).

    I can't see how there was ANY meaningful choice in that. Neither is there any choice in Him not being interventionist beyond the barest possible minimum. In and around the incarnation. No claim works transferrably or is necessary outside that as you know.

    The only question is, why ... IF, after eternity, did God change?
     
    Posted by Alan Cresswell (# 31) on :
     
    But, did He have to create the laws of physics as we know them? Could he have made a universe with different laws? And, even within the laws of the universe we have, is there not scope for infinite variation? Why create the universe so that at this moment in time the craters on the Moon look like a face, or arrange to have Alnitak, Alnilam and Mintaka positioned in a straight line like the belt of a mighty warrior? He could have easily created so things were any number of ways different. Even without doing something 'miraculous'.

    His nature may have constrained the parameters of His creation. That isn't the same as having no choice.

    I would certainly put that the other way round. God is bigger than the laws of physics. The laws of physics are part of the physical universe, part of the creation of God. The potter is bigger than the pot.

    As for kindness, that is what God is. Like love. What we experience and know of kindness and love is a pale reflection of the reality of the kindness and love that God is. God is so much more love and kindness than we experience or even dream of.

    That's fine Buddy; feel free to ignore anything I say.
    Assume that there is no fully comprehensible explanation for aging and that the ancients lived hundreds of years. Imagine also a reason this did not continue. Imagine that The effects of sin gradually played out through the generations and that in addition,God saw that longevity resulted merely In greater evil. Imagine he put a stop to this by limiting lifespans and imagine also that sin affected human health. Sin,after all Biblically is not an action only,it is also the condition that motivates the evil action. Imagine that through violence,disease and the continuous dilution of our well being, our lives are not what they once were. Imagine,but since you know best,feel free to ignore.

    And again Alan, how can God make black white? Or vary 'c'. Or Newton's 3rd law? How can He change the laws of logic which underpin reality? I realise that reality includes the wonderful strangeness that is quantum entanglement, demonstrating that paired electrons have an instantaneous delocalised relationship regardless of how separated they are (for the benefit of others). Is that a law God created? Predicating those that follow? Is wave-particle duality arbitrary? Indeterminism? General relativity? Surely only the anthropic dimensionless constants at the very most can be varied?

    As for kindness, God is perfectly kind, yes, and whatever we think of as kind, however kind we are, He could possibly point to a way in which we could be kinder. But kindness cannot be arbitrary. And even God's is highly constrained. We have to invoke it, declare it even though we do not ever directly encounter it.

    Again, He OBVIOUSLY has no choice in physics or ethics. To invoke otherwise isn't even theoretical. He CAN supervene, but, again, obviously, keeps that to an absolute minimum because it would make things worse.

    So again again, has He ALWAYS incarnated and is He currently infinitely parallely incarnate and ever will be?

    But, why should the laws of logic underlying this reality be the same for all possible realities? "Black" and "white" are words used to describe particular combinations of photons (in the case of black, the absence of photons in the visible range), so one can't logically be the other. But, if our retina responded to photons of different energies then our experience of "black" and "white" would be very different - if we could see IR (as many animals can) then what we see as "black" may be brighter than "white". Why has God created such that our eyes don't respond to IR and see black and white differently?

    'c' is a combination of other physical constants. Within this reality it is fixed. However, we can imagine other realities where the physical constants, including 'c', are different from our reality without changing other laws at all. Why did God create this reality, why not one of the others we can imagine (plus the countless more that our brains can't imagine)? OK, most of those other realities are unable to support life as we know it. But, why should God have created life as we know it, Jim?

    Did God have a choice to create? Could He have decided to not bother and just lived in His eternal "place" in His own perfection?

    Jamat,

    There are two basic assumptions in this: the bible is literal or the bible is not.
    Assuming that the bible is literal then requires a lot of justification , backwards calculation, dancing around uncomfortable passages and bizarre constructions.
    Assuming the bible is not requires reading for context, but it can provide a much more consistent viewpoint.

    ETA: Read religious text for your spiritual guidance and science texts for understanding the physical nature of our universe.

    As above. Both of my responses! I believe I pre-empted that: acknowledging that there are immutable laws and probably twiddlable dimensionless constants but with an incredibly narrow 'anthropic' range if any. Nonetheless I'll see your Bones and raise it with THE Scotty: "Ye cannae change the laws o' physics". You, Alan, have articulated Christian materialism consistently as I recall and latterly I'm tilting that way even to a default position. My side bet on divine intervention is becoming a longer and longer shot. All I'm left with is the big three (Eden is myth) and science could easily demolish the central pivot - life - this century.

    Sooooo, if life and therefore mind are emergent, God created NEITHER directly. He let matter do it. And it does it paradoxically. Unbelievably rarely everywhere else yet as soon as it rained here for a start. Sapience is similar. You need four billion years to make homeothermic, bipedal, handy, binocular, aesthetic, head at a right angle ... monkeys. Only. Not squid as well. Strong determinism means life and sapience everywhere for me.

    Aye. Or as I alluded to, DESPITE the orthodoxy of the uniqueness of the hypostatic union, if that's actually not so, He has ALWAYS created, ALWAYS incarnated and is doing so right now in some slightly off parallel universe. Which IS a heterodoxy too far, but it wouldn't surprise me if He were. God/b smack me, but not surprise.

    Depends on what you mean by "literal". A lot of self-proclaimed literalists who insist upon a literal six day creation sometime between six to ten thousand years ago because it's consistent with Genesis would balk at accepting the Bible's flat earth cosmology, mentioned obliquely in Genesis and elsewhere in the Old Testament. The basic structure seems to be a flat Earth under a bowl-like domed sky. The stars are holes in the sky and the sun an moon move around on the inside of the bowl/sky. This world supposedly floated on water and had water on the other side of the dome as well. These are the "springs of the great deep" and "floodgates of the heavens" (if you like the NIV, or the "the fountains of the great deep" and "the windows of heaven" if you're a King James sort of literalist). For some reason accepting the Bible as "literal" never seems to include accepting a literal window (or floodgate) in the heavens.

    So you keep saying, Alan, using the word 'interpretation' as some sort of excuse for ignoring what it does say and placing your materialistic philosophy above it.

    Croesus, Pray tell me where there is any definitive flat earth in scripture?
    Isaiah speaks of the circle of the earth that is translatable as sphere/globe and the jury is out on canopies. The fact is that God conceivably could have had one even though it is no longer extant.
    Foundations and windows? Rather obvious metaphors and metaphors are merely ways of indicating practical realities. A 'foundation' suggests stability ie the Earth is set in its place which is totally true in that it maintains its position in relation to the other heavenly bodies.

    See:
    Pulpit Commentary

    Verse 22. - It is he that sitteth upon the circle of the earth; rather, above the vault of the earth; above the vault of sky which seems to arch over the earth. As grasshoppers; i.e. minute, scarcely visible (comp. Numbers 13:33). That stretcheth out the heavens as a curtain. So in Psalm 104:2, only that here the "curtain" is represented as one of thin gauze. The idea is common to Isaiah with Job (Job 9:8), Jeremiah (Jeremiah 10:12; Jeremiah 51:15), and Zechariah (Zechariah 12:1), and is a favourite one in these later chapters (comp. Isaiah 42:5; Isaiah 44:24; Isaiah 45:12; Isaiah 51:13). As a tent (comp. Psalm 19:4, where God is said to have set in the heavens a "tabernacle" - 'ohel, the word used here - for the sun).

    Gill's Exposition of the Entire Bible

    It is he that sitteth upon the circle of the earth,.... Or, "the globe (z)" of it; for the earth is spherical or globular: not a flat plain, but round, hung as a ball in the air; here Jehovah sits as the Lord and Sovereign; being the Maker of it, he is above it, orders and directs its motion, and governs all things in it: Kimchi rightly observes, that the heavens are the circle of the earth, which is the centre of them, and around which they are; and so it signifies, that the Lord sits or dwells in the heavens, from whence he beholds the children of men:

    And:

    Yes, Martin, I know you do but one day when you die..what then? I would be very afraid facing that last journey with a basket of uncertainties on my arm.

    So you keep saying, Alan, using the word 'interpretation' as some sort of excuse for ignoring what it does say and placing your materialistic philosophy above it.
    Well, you claim I'm placing a "materialistic philosophy" above Scripture. I dispute your claim I have a materialistic philosophy, but I'm not going to argue semantics here (we'll probably not be too far off if you describe my belief structure, it'll just be a disagreement about the name we give that).

    What I am going to dispute is that my philosophy sits above Scripture. I hope they coexist, and that my philosophy is derived from and consistent with Scripture.

    Now, what shall we call the philosophy that you have that you bring to Scripture? For a start I take it that you bring some form of "plain meaning" philosophy, that what Scripture seems to say plainly is a solid foundation on which to build an understanding of less-clear passages. It's an approach to Scripture I have a lot of sympathy for, it has a lot of strengths. But, where does that philosophy come from? Where in Scripture does it plainly say that all Scripture should be read as plain and obvious without the need for interpretation?

    I also know that you're willing to accept that Scripture employs such linguistic devices as metaphor. How do you decide what is and isn't metaphor? Would you, for example, read the opening chapters of Genesis as being largely metaphorical? If so, why? if not, why?

    Hi Alan We have really covered all this before I think. I appreciate your considered approach. It seems to me that you are a bit like Hugh Ross. who talks about 2 books and one he calls the book of nature. He would also see himself as faithful to the Bible but also faithful to God's creation in nature. You would also, I think, like most here, see the Bible as written by men and therefore error and contradiction prone?

    I do not see this and where there are issues, would look to resolution of these. For instance, 2 lepers or one in Jericho? Well, maybe there were 2 but one gospel writer did not see fit to mention the second. Synoptics need to be read for harmony as this is the definition of what they are. Luke does not mention the wise men or magi but Matthew does. The two genealogies in Matt and Luke are different but purpose specific, Matthew seeks to see Jesus as the Royal one, King of the Jews Luke sees him as the Son of man. In short, Scripture sketches a broad canvas but not a conflicting one. It tells us what we need not what we want to know.

    I do not think I know or can deduce from Genesis how the creation happened but I do believe in Adam as the fall is needed for the gospel preached by Paul which states that in Adam all died and in Christ all were made alive. You can't have a second Adam without the first.

    I have no problems with metaphor or any other literary device and do not see them as anything other than clear ways to communicate truth. I do not have a 'philosophy' of scripture as such but I use it both as a devotional instrument and also as an overall story of history thus far. In that sense I see it as contextualising our humanity, so, evil in the world that was a stumbling block to Einstein and is to many others is really no mystery given the Satanic control of this age and the sin we are all tainted with.

    I do not subscribe to triumphalism as the Puritans did as any time the church has entered politics or sought to impose a theocracy we have had a terrible mess.

    I do not see the 'traditions of the fathers' as authoritative as the apostolic authority preceded them and the apostolic teachings are in scripture. Augustine, for instance introduced Platonic thinking into the church and Ronan Catholicism in which I was raised actually blinds by suggesting God is present in sacraments and that the Pope rather than the Holy Spirit is God's vicar on Earth.

    Finally and vitally, I believe I know the Lord which is not to say that I have any special revelation but that in my experience and it is just that, the Holy Spirit works to promote relationship with God through the Bible and so I resist emphatically, any attack on it. I have walked with the Lord 40 years now and realise that few have my mileage or can relate to it.

    Sorry, but no. If you're going to give a smart ass reply insisting God's on your side because someone else suggests that the Bible might not be literal, you obviously have a huge problem with metaphor. I'm guessing your meaning is "I have no problems with metaphor or any other literary device provided everyone else agrees with me on which parts of the Bible are metaphorical", but that's only a guess.

    Just a question? Do you actually have a clear view of metaphor? I know what I think it is. It is the use of a comparative to emphasise a literal point. Perhaps you are confusing it with myth? An eg in scripture of metaphor might be God stretching out the heavens like a curtain as in the commentary above. The fact scripture emphasises is that God did stretch them out, the image is the expansion as we understand a curtain expanding. IOW there is a literal meaning but the image is used to help visualise it by a comparison we can all understand. Perhaps you can give some sort of clarity as to where you think your 'Sorry, but no' applies? I am glad you are sorry by the way.

    Same thing..the point is that it is away of communicating and Karl, simile is a subset of metaphor. The metaphor here could actually be seen in the word stretch which also makes that a pun. [Big Grin]

    Samuel is born supernaturally of in circumstances of spiritual crisis. Mary in Luke actually echoes much of Hannah's prayer.He is dedicated to The Lord and becomes God's sole voice for his generation with a mission to restore the corrupt religious ethos of the nation. Samuel also,in a sense rises to testify after his death so I think I can see Christological typology in there.

    So this is the real issue? a genocidal God?
    Consider reasons why might God have done this and does he have a right to?

    Well he does; he is God. end of story. Do you have the right to poison a wasps' nest in your garden?

    Leaving that aside, consider the history of these Amalekites and that they particularly were used by Satan to disrupt he Exodus and consequently through Moses, God pronounced a judgement on them. He would have war on Amelek through all generations. So we have in Samuel's decree the exercise of a judicial judgement by God against Amelek.

    See also:
    Name of a nomadic nation south of Palestine. That the Amalekites were not Arabs, but of a stock related to the Edomites (consequently also to the Hebrews), can be concluded from the genealogy in Gen. xxxvi. 12 and in I Chron. i. 36. Amalek is a son of Esau's first-born son Eliphaz and of the concubine Timna, the daughter of Seir, the Horite, and sister of Lotan (Gen. xxxvi. 12; compare Timnah as name of an Edomite chief or clan, verse 40). On the other hand, Gen. xiv. 7 speaks of Amalekites, in southern Palestine, in the time of Abraham. That they were of obscure origin is also indicated in Num. xxiv. 20, where the Amalekites are called "the first of the nations." The Amalekites were the first to come in contact with the Israelites (Ex. xvii. 8), vainly opposing their march at Rephidim, not far from Sinai (compare Deut. xxv. 17, "smiting the hindmost, all that were feeble behind," and I Sam. xv. 2

    I guess this is where we must see it differently Martin, you from your view of 'God would not do this so this is not God,' and me from my view of 'He did it as a necessity to save Israel from corruption and fulfil his purpose of bringing a positive resolution to history'.

    Interesting that it was an Amelekite who helped David rescue his captive families a bit later on. Given this I think I would see the Amelekite nation as under judgement. They were descendants of Esau and in Romans it is quoted, 'Esau I hated' much loved of Calvinists.

    I think the answer to their dilemma is that it was, contextually, Esau as a 'nation' that God elected to judge. Remember it was Esau who despised his inheritance but individuals are not IMV predetermined to destruction.

    In the end though accusing God of genocide does not get one very far. The fist shaking response to judgement or misfortune is a dead end path in the search for God IME. We simply must commit to his integrity if we want to find his reality.

    If, as you say, God is God, then because God is a creator, can destroy Her creations if they fail to please Her, correct? Well, I didn't create the wasps. I'm a non-God in a non-Eden. So the question is irrelevant.

    Really, though, I'm always amazed at how important it is, apparently, that God be a total badass - so powerful and mighty and wise that even when He does horrible things, they're automatically right. Which reminds me of this (paraphrased from foggy memory) exchange from Candide (the opera):

    So pedantic. Essentially and for practical purposes, metaphor is a direct comparison in which one element of the comparison is used to elucidate meaning. eg a tempestuous exchange (acrimonious.)Simile is the same thing only the comparison is indirect using 'like' or 'as.'eg a storm like atmosphere round the dinner table.

    Why do you need to ask? Of course we must love each other and also do good to those who do us disparagement. It is the great skill of survival not to let oneself be overcome with bitterness.

    However, God I am convinced, MUST have reasons for his OT judicial judgements. His decrees are not for us to judge but to accept the paradox that alongside them he finds a way to confront all individuals with his love.

    He does judge nations because, I think, of the Satanic powers that motivate them hence the Amelekites but seeks to reach individuals. If there is one thing that prevents this it is our pride and if there is another, it is our hardness of heart. Jesus was always most grieved for the Pharisees because they rejected the plain evidence and proof of his Messiahship.

    Samuel was a great man of God. He could not have been greater. And he could not transcend his time. He KNEW that he was being faithful to God in murdering every man woman and child of his enemies. And he was. But not in the sense he thought.

    There you go. Also if evolution is true it is unlikely our stubbornness, pride and cruelty would have been positive traits in natural selection. (Don't worry Martin,your irony is not in vain.)

    NO shocker, but your words do indicate a lack of understanding of the mechanics of natural selection and the dynamics of human interactions.
    Many traits considered "bad" are actually advantageous.

    You seem to be missing several significant points. Some of them might be:

    1) Even assuming "stubbornness, pride and cruelty" are traits we inherit through evolution (that's an assumption in itself), it is well known that evolution can produce negative traits. An extended period of evolution under a particular environment can create traits that aid survival there, but in a different environment are negative. An example would be the genes that cause sickle-cell anaemia, this condition is a negative trait but the same genes give malaria resistance which is positive.

    2) We know of plenty of examples where development leads to previously useful traits no longer being good and useful. As infants we wore nappies, it was good and useful that we did so avoiding nasty messes for our parents to clear up. We're called to be adults, to put away the things of childhood, sin would be a refusal to grow up and put away those childish traits. Or, to pick up another analogy, in sin we're like lumps of mud in crude human-like form, God wants to breath into us to make us truly human beings.

    3) We know plenty of examples where development produces unwanted traits. When adults need to wear nappies we consider that this is a sign of something being wrong, an illness of some sort. As we age we develop arthritis, dicky hearts, cancers ... all of which we consider to be illnesses in need of treatment. Could it not be that evolution, on it's own, when intelligence evolves inevitably introduces some moral illnesses? What we then need is a doctor to heal us.

    Do you get even the theory of natural selection?

    In a setting where a group (or species) is either under threat or is having to compete for resources, food, etc, with another group or species, then stubbornness is one of the key qualities that is needed: the ability to persist in attempts to secure the scarce, fought-over commodity is going to be vastly preferable to any sense of fairness or willingness to concede to others.

    Similarly, pride can also be put to good use in the pursuit of a hard to achieve goal.

    As for cruelty, in situations where it may come down to kill-or-be-killed, individuals who are prepared to exert physical pressure, cruelty, perhaps death, are far better equipped to survive than those more inclined to support fair-shares-for-all.

    No. He can't possibly.

    Linking disbelief in evolution with salvation and Christ is quite a fragile position it seems to me. It implies that in that purgatory thread on what evidence would make one doubt the resurrection, the answer would be "solid scientific evidence of evolution". In which case I can understand the need to argue it through quite vigorously.

    Jamat, it's an interesting question how you would advise a scientist like me who confronts the biological evidence of evolution every day in their work and has little room for doubt that something very like evolution took place.

    It seems to me there are three options; a) lose faith in salvation b) develop a world view that allows for both evolution and Christ or c) not bother to reason it through, simply concluding that both are facts and that certain apparent contradictions remain.

    I've opted for c).

    I got into a conversation about creationism with yet another person on Thursday - where the argument was that evolution is no longer happening, mutations might be, but evolution isn't. We got chatting a bit further - and this guy hadn't realised that the evidence for evolution didn't just come from the fossil record but also from DNA and other sources too, so that it isn't just a construction from one dimension, but an understanding built up from a number of different strands. He's obviously reading books on creationism and the need to protect the Bible - and we chatted a bit about biblical belief being metaphorical and wider than just literal until Usher put dates into the record and came up with the 6000 years of creation Also that there were scientists such as John Polkinghorne who balance science and theology.

    You are reposing a lot of trust in Science then. Science is limited knowledge, a moving target. Your own precious evolutionary assumptions viz, that macro evolution occurred, are not proven, and untestable. Dinos are..how old? Why did Mary Schweitzer fine real blood in a T Rex bone? Dating methods? Why such variations and just using the dates that suit our assumptions? Scientists are humans who tenaciously cling to careers.

This was surprising, but it wasn't (a) impossible according to the age of the animal, nor (b) blood, not, indeed (c) evidence against the commonly accepted period during which T. rex lived.

    What it was, however was evidence for the evolution of birds from dinosaurs, as the sequenced proteins showed close links to those of extant birds.

    That some creationist liars have chosen to try to tell you that Schweitzer's work somehow is a problem for mainstream science speaks volumes. You've been lied to by your creationist sources again Jamat - and if memory serves this is why you got your arse handed to you on a plate last time - you tried raising hoary old creationist canards. Why do you not see the pattern here? The lying professional Creationism machine is a lying bunch of lying liars who lie. Consistently, Repeatedly. Depressingly.

    They repeat lies even when told they're lies. Repeatedly. I ran into that when after a conversation at an AiG event in Edinburgh one of the speakers asked me to review an article he'd written on carbon dating for their journal. There was an absolutely enormous error in it that totally invalidated the main point being made - he was claiming that measurements of background for AMS 14C analysis showed that the earth is no more than 80,000 years old - based on the convention in the radiocarbon community to give 14C concentrations as a radio-carbon age (and, backgrounds for good AMS facilities work out at around a radio-carbon age of 80,000 years). That is, these measurements aren't of the age of the fossil carbon (coal) being measured but of the performance of the instrument. Despite an extensive exchange of emails on the subject the author still published his article without any reference at all to the points I had made. The journal never published the letter I sent them either. I never bothered to do that again.

    Normally yes. But under the right conditions, some material can survive. If you follow my link, there's a hypothesis that it's connected with iron. Blood however does not survive; that's the lie Jamat was sold. Remains of red blood cells apparently did.

    The processing and measurement of a sample will introduce a very small amount of modern carbon into the measurement. The glass work for sample preparation is purged (usually with nitrogen) to remove contemporary atmosphere, as is the beam line of the accelerator. But, there will always be a very small residual amount of lab atmosphere in the equipment which will contain a very small amount of 14C. So, labs routinely prepare blanks to run with their samples, taking small quantities of coal and processing them through the same preparation lines as the samples. The best labs can't get the contaminant levels below the equivalent of 80,000 years or so - which in practice results in 14C ages over 40,000 years having substantial uncertainties. But, no one expects radiogenic dating to be very accurate 10 half lives into the decay.

    The measurement uncertainty derives from three elements - the background, the standard and the sample. I've mentioned the background. The standard is a reference material of known 14C concentration run to measure the efficiency of the system. For each of these three measurements you will have an uncertainty that will be the square root of the number of atoms detected - so, if you detect 100 atoms you have 100 ± 10 atoms (10% uncertainty), but naturally you really want to count a lot more atoms than that. How many will be a function of how long you measure for, and the sample size (which for AMS is fixed - though you can run several aliquots from the same sample) - that basically means spend more money. But there are diminishing returns, measure 4 samples and you only halve the uncertainty.

    Generally the background and standard will be measured lots of times - both to reduce the contribution from these to the overall uncertainty and to confirm the system is performing as it should (increase in background means you have a new contaminant somewhere, decrease in standard means you're losing sample somewhere).

    At 10 half lives, you will as noted reduce the counts by a factor of 1024 (to be precise). That will result in a 30 fold increase in uncertainty - so if you measure a new sample to 1% precision, your 50,000 year old sample (assuming all else is equal) would have a 30% uncertainty. Ignoring the influence of the background uncertainty, which will increase the overall value (insignificant for younger samples, getting much more important for older ones). The 80,000 years will be the radiocarbon age at which point the sample counts are within uncertainty of the background for a normal analysis - if you want to pay the money you may be able to push the age back a few millenia.

    The point the guy I was corresponding with never got was why labs think this is an important number. "Why do they publish this in the peer reviewed literature?" was the question he kept asking - totally failing to understand that it's a simple measure of the quality of analysis, the lack of contaminants in processing and measurement efficiency, and labs want this published so they can say "we're better than anyone else" and get people to pay to have their samples analysed there - not the most objective and impartial of reasons, but the bills need to be paid somehow.

    Just to move away from the technical stuff for a second - the reason they don't disbelieve lies even when they're told lies must be confirmation bias. Easier to latch onto any crumb of evidence that might support your position than to engage with the complexity of an argument which is against it.

    So in Alan's example, easier to believe that Alan is wrong because his answer isn't in the acceptable form than to believe that the foundational belief needs revision.

    I don't think many think that they're actually spreading lies, they've just convinced themselves that things can only work within their very narrow framework and reject anything which doesn't conform to it.

    There's more to it than that. It's about belonging. If you belong to a group whose identity is partly tied up in denying evolution, then coming to believe evolution puts you outside of the group. If this group is your entire social circle, that's just too scary. That can drive a hell of a lot of confirmation bias.

    From my experience, for many their identity is not "partly tied up in denying evolution", but entirely tied up in denying evolution. I attended a meeting where Ken Ham was the main speaker, and for several minutes of his talk he had a slide up showing a cartoon of a church built on top of a large rock labelled "Creation" with a set of catapults labelled "Science" lobbing rocks at that foundation. And, he spent his time talking about how Creation was the foundation upon which the Christian faith is founded, and without that the whole of our faith is worthless and collapses which is why "the enemy" uses science to try to undermine the foundation of our faith.

    I so wished the worship time had included singing "The Churches One Foundation is Jesus Christ her Lord" just for the irony factor.

    The battle between religion and science is entirely ideological and mostly orthogonal. What polemicists generally mean by "science" is the metaphysical assumption that we exist in a purposeless universe with immutable laws that emerged from nowhere for unknown reasons, and in which we are biological robots at the whim of genetics erroneously imagining that we are conscious. Or as the late Terence McKenna put it, "give us one free miracle and we'll explain the rest".

    It's a position built on a mountain of assumptions, and tells people they are unreliable witnesses (unless they're in a laboratory) and should only trust a priesthood of materialists in their assessment of the abstract platonic reality in which we imagine we exist. It's fundamentalism the equal of any screwball religious sect, but presented by in a suitably patrician tone people lap it up because it saves thinking about the issue.

    Well, that's scientism, not science. Most of the scientists I know don't go in for metaphysics, really, since science is built on observations.

    In fact, Bacon was one of the thinkers who advised people to stop talking about Aristotle, and rely on the senses. You can do this, while being a Christian, Muslim, Hindu, or whatever.

    I think you're being optimistic. UK science education is predicated on an assumption of materialism, and the philosophy of science rarely if ever gets a look in on science undergraduate courses. Overseas non-Christian graduates are more likely to hang on to forms of belief concurrent with their scientific discipline, but British scientists are overwhelmingly on message with a Dawkinsian world view.

    New Atheism has made all religious faith synonymous with young earth creationism, violence and medievalism, and vocal objections to that parody are the exception within the science community.

    This takes us back to methodological and metaphysical materialism. Are young scientists really taught that matter is all there is, and religion is bollocks? This is quite different from an instrumental materialism, which doesn't delve into metaphysics.

    I was actually taught (on a postgrad history of ideas course) that science does not set out to describe truth or reality, but I accept that there are probably wide variations.

    If you ask most atheists to explain why they are atheists, they will almost without exception claim that materialism/physicalism exhausts the possibilities for reality without the necessity for a deity. I'm discounting instinctive atheists who are happy to leave things at "it's all bollox, innit" and eschew any reflection on the matter.

    The mind set that claims we are epiphenomenally conscious observers of a reality that is exclusively machine like, has been the dominant purview of most science, with the possible exception of quantum physics which privileges the observer in a novel way. Since 9/11 in particular, polemical atheism of the kind propounded by Sean Carroll, Jerry Coyne, Richard Dawkins, Martin Gardner, P Z Myers, Michael Shermer and Neil deGrasse Tyson has sought to equivalence all non-materialistic views of reality as a foothold for the Inquisition. This suspicion of the non-physical makes scientists keep their heads down and allow the materialism paradigm to dominate the discourse. A few scientists are happy to navigate other waters but they tend to be established names who don't mind the inevitable crank accusations that follow. It's clear that some disciplines cannot sustain the machine analogy indefinitely, but as Max Planck said, science does not progress by convincing doubters, but because a new generation emerge who are familiar with the material. It advances "one funeral at a time".

    I'd argue it's more a suspicion of the non-testable keeps scientists in the realm of materialism. It's easy to demonstrate that a magnetic field will deflect an electron. It's impossible to create a test to answer the question of whether electrons are deflected by a magnetic field because God wills magnetic fields to deflect electrons.

    The question is whether the billiard ball view of reality exhausts all there is to say about it. A good scientist keeps a completely open mind, limiting him/herself to the data and not extrapolating further than its immediate implications. Unfortunately that model does not typify the public face of science, and political materialists like Richard Dawkins are given prime time TV programmes and book deals to proclaim nonsense like science should dictate morality and people who don't terminate disabled children are irresponsible.

    Within that world view, the one where we only imagine we are conscious and he cannot condemn murder on moral grounds, the blurring of materialism and morality makes perfect sense, because only the first is real. We really are only a collection of genes and synapses programmed by something called memes (an idea borrowed wholesale from semiotics and with no scientific application to biology) to reproduce. So looking for a phenomenon like consciousness (individual or deistic) is a fool's errand because science tells us it cannot exist.

    I have to disagree here. Crafting new hypotheses in advance of data is a crucial step in the scientific process. I'd say it's a particularly bad scientist who never crafts a speculative hypothesis.
     
    Posted by romanesque (# 18785) on :
     
    It may be if the scientist is scrupulous in the scope of its implications, but becomes pseudoscience if he publishes what he expects to find. An example of this is the "file draw effect" whereby scientists only publish 5%-10% of their data, the stuff that matches their predictions. A pharmaceutical company recently decided to test 50 of the main experiments that comprise biomedical science and 45 were found to be non-replicable - 90% were wrong. People publish their best results and filed the rest away. Another company found this unlikely and did their own replication experiments with very similar result, most was duff science.

    It's difficult to know how widespread such practice is within the material sciences, but I expect it's more common than most people imagine, as tame peer reviewers underwrite experiments that confirm what they expect to find. This has called for demands for data to be published on an on-going basis with a time limit set on its conclusions.

    So, you would consider a theorist publishing her new idea as pseudoscience just because she may not have the expertise or access to the equipment needed to test it? So, a potentially useful insight remains hidden and unpublished? Scientists publish what they find, though I know from experience it's very much easier to write a paper reporting an experiment that has results in line with the expectation than one where the results are not what was sought (or, indeed something ground breaking found fortuitously).

    quote:

    I guess most of those here who are practicing scientists, especially in universities, have attended courses on research integrity. Both universities I've been at in the last few years have not only had such courses, but they're compulsory for all research staff.

    Selectiveness in data used in publications is one of the things that gets covered in such courses, as a clear example of a practice that is unethical. It happens not because there is a flaw in the scientific method, but because scientists are human and as flawed as all other humans. Positive results are easier to publish (for a start actually writing the paper is much easier), and usually generate more citations (which is important when you have stupid politicians decide that citation metrics will be used to judge the quality of research and hence whether it will be financially supported - which, again, is nothing to do with the scientific method). With the increasing use of online publication and the ready availability of data repositories the full data sets of experiments are increasingly becoming widely available (and, many journals will now reject a paper out of hand if the source data is not deposited either with the journal or some other open access repository). Which doesn't address the difficulties of publishing null results, but is a step in the right direction of addressing the file draw effect. The biggest difficulty is that there are a wide range of options as to why an experiment didn't work - the conditions where not optimised, the background noise was too large to see the effect, a piece of equipment was broken and not noticed, there was a flaw in the analysis, etc ... and at the end of the list the hypothesis being tested is flawed. It's almost impossible to discuss all of those possibilities in a paper (though one should be able to check the analysis and equipment).

    Faith and science are sometimes separate, other times not. If you're testing the validity of the Dead Sea scrolls you'd better have a little physics and chemistry to fall back on. If you want to know which gospels are consistent, you'll need to cross reference a whole heap of data that comes under social science. You may even require a knowledge of theology, a study of nothing as Richard Dawkins' described it.

    You guys remind me of a kitsch postcard of the Ascension I once saw, where a rigid Jesus rises at 45 degrees with a jet exhaust emerging from his toga. Literalism gone mad.

    Sorry, is this a Christian website or a The Skeptic? Assuming the first, a load of stuff happened between a virgin birth and a veridical intact bodily ascension. If you think water and wine, loaves and fishes, and reanimating dead people is a trope, a metaphor, a synecdoche, then consciousness studies may be pearls before swine.

    I've already refuted all your points. Not so much in the sense of actually offering any coherent argument or comprehensible points, but in a vague and "non-material" way. It's not my job to "joint the dots" or "construct an argument" or "be coherent" for those who are unwilling to do those things on my behalf.

    It's a serious question. If someone self identifies as a Christian I assume a belief in the supernatural until they state otherwise. Therefore concepts like conscious non-locality isn't such a leap. If you think all religion is bollocks - to use the word of the day - then I can't be arsed arguing fundamentals.

    Hosting - Formal Warning

    Romanesque, you’re relatively new but need to understand that you’ve crossed the line completely for how we define personal attack on the boards outside Hell. You’ve made a succession of personal attacks which can only be made on the Hell board. Making such attacks on the boards outside Hell is grounds for suspension or banning. The lines here may be different to those you are used to - so please read carefully.

    Attacks which are allowed:

    Robust attacks on arguments eg. someone is talking bollocks

    Attacks on collective groups - scientists are X/do X bad thing Atheists are Y/ do Y bad thing etc.



    Attacks which are not allowed on this board and must be kept to the Hell Board

    Impugning an individual shipmate’s morals/integrity as a christian or scientist = personal attack, must be done on the Hell Board and not done here.

    ‘You are Bishop David Jenkins and I claim my five pounds.” This is a personal insult - it belongs on the Hell Board.

    Another out of bounds personal attack - “When dealing with people who both snippy and shrill I find it easier to provide them with something to chew on so we're on the same page, than knock insults back and forth.” - this sort of personal attack will lead to banning or suspension if posted outside the Hell Board.

    Attacks on the other posters on the thread as shipmates- “You guys remind me of a kitsch postcard of the Ascension I once saw, where a rigid Jesus rises at 45 degrees with a jet exhaust emerging from his toga. Literalism gone mad.”


    Please read the board rules:

    quote:

    3. Attack the issue, not the person

    Name-calling and personal insults are only allowed in Hell. Attacks outside of Hell are grounds for suspension or banning.

    4. If you must get personal, take it to Hell

    If you get into a personality conflict with other shipmates, you have two simple choices: end the argument or take it to Hell.

    Please remember that host rulings are not discussed here - if people want to query or discuss host rulings they must do so on The Styx Board and not here.


    Can I ask other posters not to reply in kind? Lil Buddha please regard this as a personal conflict which must be stopped or taken to Hell. Please don’t reply in personal terms to any attacks. Similarly - Romanesque you have got far too personal with Alan Cresswell and Lil Buddha and need to stop the personal conflicts or start a thread in Hell to carry them on.

    Croesos putting a smiley face on and '/snark' doesn’t magically stop something from being personal attack. Please take it to Hell and do not make personal attacks here.

    If you are more personally annoyed with another poster and their attitude than you are interested in the general topic of discussion - please consider whether you ought to start a thread in Hell and post there and not here.

    Can people either dial back the personal content here, or start a Hell thread please?

    Thanks,
    Louise

    Ok, let me make myself clear so I can be reprimanded or banned or whatever for things I have done and think rather than things I haven't or don't.

    First, my attack wasn't on science which I've made clear is an utterly blameless methodology concerned with forming conclusions about the physical world. My attack was on philosophical materialism which in many peoples' minds is synonymous with science. It isn't my fault that people conflate those two things, indeed there's a political drive to ensure the lines are deliberately blurred, but they are different.

    Materialism is the philosophical position that there is only matter. If people make room for mind, consciousness as more than an illusion, deities or the supernatural in any way, they are not materialists, and my rebuke is entirely to those who those who present that philosophical position as beyond intellectual reproach. My argument isn't with atheists, it's with people who present materialism as a justification for atheism, especially when it involves condescension towards alternative views as ignorant. I have no interest in using the board as a ministry to sceptics, or indulging in Christian apologetics, I want to knock ideas around among fellow believers of any stripe. If Dead Horses is a sceptical materialist bulwark in what I took to be an Anglican website, I'll save myself a heap of time by avoiding it entirely, and if the entire board has succumbed to lifestyle scepticism I'm happy to disappear.

    If people care to look, at no point have I used insults unless people have insulted me first, and mostly not then. The David Jenkins joke was pointed at someone who thought the whole idea of the supernatural preposterous, which is still an outlier among Christians thought, but was offered as axiomatic, and in an openly snippy way. I was asked to support my "generalities" and when I offered links was accused of giving homework. Some ideas can't be reduced to sound bites for general entertainment.

    Your posts were a very long way from clear on that point. I would actually find common ground in criticism of the common view that philosophical materialism and science are synonymous. And, I would (naturally since I'm a theist) have many criticisms of philosophical materialism - though we may differ on the nature of our criticisms.

    However, much of what you have written here is totally irrelevant to that aim. Issues with publication of null results, and with the peer review process, for example.

    And, though I can see how your claim that "UK science education is predicated on an assumption of materialism ... British scientists are overwhelmingly on message with a Dawkinsian world view." is relevant to your position, that is a statement that needs some serious support. Because, as I said, I've spent my adult life in UK science education (as a student, and then as a researcher - with some short periods in Japan) and I still don't recognise that description. Of course science is based on a form of materialism, but it's a pragmatic rather than philosophical position. Science can not proceed if every unexpected result is attributed to a non-material entity. As famously declared we have no need of a God-hypothesis in seeking to understand the physical universe. It doesn't follow that therefore we're all philosophical materialists.

    And, especially among the few bioscientists I know, Dawkins is more oftenly held in contempt than reverence. Most of us look at his early works and admire the clarity with which he described evolution and associated biochemistry, then start banging our heads on the wall as he extrapolates from that to his philosophical position - even more so those who have some philosophy of science in our background (I would also agree that we fail our students in not including philosophy of science within our undergraduate courses).

    If Dead Horses is a sceptical materialist bulwark in what I took to be an Anglican website
    The Ship is a majority Christian site, but it's not Anglican. It's probable that although Anglicans are likely to be the biggest single grouping they'll be a minority as we have a large number of Catholics, Orthodox, Presbyterians, Methodists, Reformed and other Christians, as well as people of other religions and none. I guess that misunderstanding accounts for why you chose to call Rupert Sheldrake an Anglican (he isn't, beyond being christened in the CofE which would make me an Anglican too, and I've never regularly worshipped in an Anglican church). He's also not a biochemist in any realistic sense either.

    It seems there are misunderstandings on both sides.
    In my post at 16:22 I said "It may be if the scientist is scrupulous in the scope of its implications, but becomes pseudoscience if he publishes what he expects to find." In the context of the previous discussion I thought it self evident that I was inferring pseudoscience in publishing "only" what he expects to find, abandoning any other result as contaminated. This is a real problem for physical science, as it builds a world view that niche results are typical, rewards those that are on message, and removes challenges to orthodoxy by setting the bar higher on the basis that "extraordinary claims require extraordinary evidence", a thoroughly unscientific approach to methodology.

    I do believe materialism is an a priori assumption of contemporary science, not least in education, and can site a number of scientists who agree that's the case. Let's be clear, philosophical materialism is the position that matter exhausts and explains reality in its entirety. It rejects any other factor as erroneous and superfluous, and in that sense it is ideological, a position manifested by endless flame wars between followers of "science" and "believers". Note quotation marks.

    Richard Dawkins is one of the protagonists in this ideological approach to science, a mantle taken up by other scientists which I listed, but also cultural commentators, journalists, comedians, et al who are increasingly vocal in laying the world's errors at the feet of Believers and its salvation in Atheist Materialism. This despite the body count of institutional atheists regimes (societies that enforce atheism at the point of a gun) far outweighing religiously inspired or backed wars.

    I assumed Ship of Fools was a principally Anglican site, plus Others. You are incorrect in your observations re. Rupert Sheldrake, he is a practicing Anglican and attendee at his local church. He is also an esteemed biologist with a stellar career in academia and research, who fell fowl of the mainstream by introducing the idea of mind into a physicalist hegemony for which such notions were toxic. The former Editor of Nature demanded his book was burned as heresy. That is what people who introduce consciousness to an unconscious universe can expect.

    I would distinguish between methodological naturalism and metaphysical naturalism.

    Methodological naturalism is a variant on Occam's razor. If you can explain phenomena in terms of matter, forces, and mathematical entities that you're already using in your physics then you do so. All things being equal you prefer an explanation without action-at-a-distance, such as Descartes' vortices, to an explanation with action-at-a-distance, such as Newton's mechanics. In that case, all things weren't equal and Newton won out.

    Metaphysical naturalism is indeed an arguably unwarranted extension of the principle from a pragmatic guideline to a philosophical position. (I believe most scientists would reject metaphysical naturalism at the level of mathematical entities and scientific laws. Scientists tend to be realists about the things they're investigating.)

    Conversely, the history of science is littered with ideas that were rejected out of hand to be subsequently proven, including, disease spread by germs, bacteria causing stomach ulcers, continental drift, Boltzmann's atomic theory, etc. Some will cite this as evidence that science is self correcting, but it could have saved itself a few hundred years and any number of careers by adopting an open mind. In the case of materialism it may defer any correction permanently by only looking for and confirming observations that fulfil its prejudices. Dean Radin is doing some excellent meta-analysis on the influence of mind in the material with compelling data.. for those who care to do their "homework".

    Incidentally, not all atheists are materialists. There are a number who take part in the debates over consciousness, who are dualists. The most famous example is David Chalmers who (I think) coined the term 'the hard problem of consciousness'.

    Another well-known example is Nagel, whose book 'Mind and Cosmos' appears to argue for the non-theistic dualism of matter and mind.

    It is a hard problem, although one should also mention those who argue from incredulity - I don't understand consciousness, therefore God.

    It is a hard problem, although one should also mention those who argue from incredulity - I don't understand consciousness, therefore God.

    It generally comes down to what one means by God. For an Idealist mind is primary and all matter a manifestation off it. Therefore mind-at-large might be something very like God. A Panpsychist adopts a similar but subtly different approach, believing all matter is conscious, though not necessarily what a human might mean by conscious. Some (especially the more polemical variety of atheist IME) get no further than a Renaissance fresco of God, a grumpy, hung-over dude with an accusing finger and a casual approach to personal grooming. An embodiment of all the more challenging bits of the OT, in a down at heel artist's model.

    The problem of consciousness is indeed a hard one as Chalmers' indicated, as there is no viable mechanism by which consciousness emerges from unconscious matter. This has lead more thoughtful materialists (Daniel Dennett in particular) to conclude we cannot be conscious at all, and the illusion is simply smoke from the biological machine. Most side step the issue by insisting consciousness emerges by the process of conscious emergence, and leave the details to the devil. The important thing to remember is scientifically speaking, no one has a bleeding clue and no amount of patrician dismissal or hand waving lends their theories any more weight than the bloke in the chip shop.

    I suppose there is really something to collective consciousness (CC). In this case technology accelerated the growth of this blob of CC in Darwin's direction. Hard to predict what smaller blob is growing now that will become the next big one. Is it the alien religion the next thing?

    Hold on a sec. Doesn't that fall foul of your stance against materialism in science? Of course I'm still waiting for your answer to my earlier question about how you do science without reference to the material universe. I don't see how you can square that circle and still call it "science".

    Another interesting question is the bounds of "materialism". Does Newtonian gravitation count as non-materialist because in addition to matter Newton postulated an immaterial force ("spooky action at a distance") that acted on matter? Is it 'materialist' to model electromagnetic interactions in terms of force carrier particles but non-materialist (immaterialist?) to model the same interaction in terms of electromagnetic 'fields'? And does the approach used affect the validity of the results?
     
    Posted by Aijalon (# 18777) on :
     
    I think there is always "something" behind the thing that we are observing, looking for the next layer. Materialism might simply be defined as the continued effort to explain the something. But what may be harder to nail down is whether it was predecided that Materialism is on the correct path to the ultimate something at the end of it all...

    Is this a correct conclusion is different than, were we heading in the right direction when we made this conclusion.

    If the Higgs Boson is the something, once that is resolved, there will be a next something. What is the ultimate objective we hope to find?

    An issue with "Darwinism" though is not that people were ever curious enough to explore evolutionary links, either macro, or micro, but that Darwinism is not readily able to be rolled backward -if it needed to be- because scientists view their notion of progress and purpose to be much like a religious purpose - for "the good".

    So if any branch of science needed to retrace their steps, go back, look for the right road, they are reluctant to do so because so much effort has been spent on going in one direction. It lends insult to what is considered honorable, or for the good of society.

    Rather than being encouraged to explore new directions, it is discouraged and mocked to be the first one or first group to say "let's look at this a whole new way" - or worse - lets stop studying this and moving in this direction, and study this new idea.

    Has anyone ever studied a map and realized there was a faster route, but found it hard to make the decision to turn back because it was uncomfortable? Something like that.

    What you are describing is bad practice.
    pseudoscience:
    quote:
    a collection of beliefs or practices mistakenly regarded as being based on scientific method.
    quote:
    "extraordinary claims require extraordinary evidence", a thoroughly unscientific approach to methodology.

    It is very scientific. If I claim yogic flying is real, I would need to show that what I am doing exceeds the results of physically launching my body forward whilst in the lotus position.
    This is also the standard in more accepted theory.


    quote:

    This is something that whilst perhaps not completely wrong, is an inaccurate way to frame the debate. But that is a discussion for another thread, perhaps.

    Not sure what you're getting at here. Yes, it would be convenient to "roll back" certain mutations, like antibiotic-resistant bacteria, but I don't think you can really attribute that to the actions of "scientists". It seems like that's something more inherent in descent with modification than anything scientists declared by fiat.

    Hold on a sec. Doesn't that fall foul of your stance against materialism in science? Of course I'm still waiting for your answer to my earlier question about how you do science without reference to the material universe. I don't see how you can square that circle and still call it "science".

    Another interesting question is the bounds of "materialism". Does Newtonian gravitation count as non-materialist because in addition to matter Newton postulated an immaterial force ("spooky action at a distance") that acted on matter? Is it 'materialist' to model electromagnetic interactions in terms of force carrier particles but non-materialist (immaterialist?) to model the same interaction in terms of electromagnetic 'fields'? And does the approach used affect the validity of the results?

    No, of course the recognition of matter and its habits does not negate other possible influences. I didn't miss your previous question but assumed in the light of what I'd said, and the speed of incoming posts, the difference was self evident.

    Briefly, and very roughly, the alternatives include (but are certainly not restricted to):

    An entirely material universe with immutable laws of unknown origin that emerged full formed at the Big Bang. A reality akin to a Platonic or mathematical realm of pure abstraction and devoid of consciousness, not least the conscious mind of a deity. The human observer is only epiphenomenally conscious, the result of incipient survival mechanisms and genetic imperatives that have seduced him into an illusory world view of which he is a wholly unreliable observer.

    A similarly sealed material universe, machine like in every detail (even if we don't currently recognise the precise nature of the machine), put in place by an infinitely creative mind in which the creator plays no further part.

    The same universe, but having an ongoing relationship with the deity, a relationship that can be detected through manifest interventions like miracles, and/or subtly via human nature, which reflects something of the nature of God.

    A universe like the above, but which can only be detected by conscious mind, and which may be contained entirely within it. As there's no way of knowing anything outside conscious experience, there's no reason to believe such a domain exists.

    Each are philosophically consistent, in so far as philosophy is the study of what it is possible to know, but take a different perspective on parsimony. For instance materialism is difficult to square with qualia and the unavoidability of conscious experience, Idealism is theoretically consistent but doesn't accommodate the apparent immanence of matter.

    Choose your poison.

    I'm not sure why these unanswerable questions are relevant to Darwinism specifically or science generally. It starts to sound a little like angels and pin heads*.

    *This is actually a modern myth. Theologians in the Middle Ages didn't actually argue about the number of angels that could dance on the head of a pin. They argued about important stuff, like whether or not angels defecated.

    Stephen Meyer proposes a challenge to Darwinism. Personally I find the term intelligent design unsatisfactory, as it reduces creativity to process, and if there is a conscious mind at work its immanence may too apparent to perceive "logically". God may submit to logical analysis, or deduction may be a tiny subset of what's necessary for navigating the deity. Perhaps instincts like love connect to the creator in a way deconstruction does not? Most people would say human beings contain instinct and deduction.

    My point re. scientism is science education privileges method over philosophy, rewarding a "shut up and do the math" approach for analytical minds. This is exploited by people like Richard Dawkins who state that philosophy is irrelevant to science, even though science is rooted in natural philosophy, and introducing an ideological element to a blameless method of observing the physical world. Physicalism is assumed, physicalism plus an undetectable deity for sentimental reasons if absolutely necessary, but suggestions that mind may be an a detectable agent is career suicide and for woo woo mongers only.

    How about "cdesign proponentsists"? It's an interesting 'transitional (linguistic) fossil' between creationism and intelligent design. I believe Meyer was involved in the publication of Of Pandas and People, though I don't think it was that particular edition. I'm mostly familiar with him as the author of the "Wedge Document", outlining a PR campaign to sway scientific consensus. So yes, I agree "Stephen Meyer proposes a challenge to Darwinism", I just disagree that he does so on any grounds that could be considered "scientific".

    From this I gather that your big complaint isn't that there's "an ideological/philosophical element" in science education, you're just upset it's not your ideology/philosophy.

    I disagree. The scientific method requires experiments to have results which can be observed, for example. This would seem to be the dreaded "materialism" you've been complaining about, that "results" without any physical evidence aren't considered scientific.

    Don't concepts like "in order to have your hypotheses accepted you need to produce evidence" count as "ideology"?

    No. You are stating a method, not an ideology. Science is a method of procuring data or evidence. An ideology tells you what to think about data or evidence regardless of what it is or shows. So someone could be ideological about a theory, such as creationism, and the method of scientific data collection would refute it and an ideologue still holds the disproven theory.

    Yes but also no. It is certainly true that Science follows a particular philosophy and that almost everyone has signed up to it to the extent that those who fall foul are named, shamed and excommunicated.

    At the same time, it is hard to call it an ideology when it boils down to "do your damn work openly and honestly". That's like saying that the civic expectation on a policeman to work honestly and fairly is an "ideology". Err..

    Not true. The current mania for "evidence-based medicine" demonstrates perfectly how a scientific principle turns into an ideology. The critical step is an obfuscation: behind the scientific methodology sits the process of selecting the hypotheses to be tested, and before that, the problems in respect of which hypotheses and solutions are to be developed. The "evidence" produced by the development and evaluation processes is used to hide that process of selection, and protect it from questioning. That is how a scientific method becomes an ideology, and it's everywhere.

    That may somewhat overstate it MT. There's a lot of nonspecific factors embedded in medical care, particularly at the level of family physicians. Medicine is both a science and an art. It does no good to have a physician (or nurse practitioner, physiotherapist etc) prescribe the exactly right evidence based treatment and have the patient not adhere to the treatment. -- though on the other hand, we have practitioners who manage the communication and adherence to treatment plans rather well, but are not very good at applying evidence to diagnosis and applying the right treatment, thus command great adherence to plans, but to the wrong ones.

    To get back to the topic, we have good evidence, from multiple independent data sources that converges on the same interpretation - thus evidence for evolution. We also have people who take one data source and run with it to the wrong conclusions, not taking into account other sources. The one I've seen most is the evolution of the eye, which has actually evolved some 5 times independently, which refutes the anti-Darwinian idea that such structures cannot be formed by natural processes. Others are structures that allow flight and swimming (wings and fins/flippers).

However, there are queries about his interviews in that he changes the topic of the interview at the last minute to throw the interviewee off balance and make himself look good (from that Rational Wiki article), and a critical review of his book here querying his ideas and methodology.

    It's a bad thing if it obscures the decisions taken before evidence is gathered. For example, the use of aspirin in many contexts probably doesn't stand up to the scrutiny of "evidence-based" zealots, but that's because no-one can make enough money out of it to pay for that scrutiny to take place. My point is that, without a rigorous and publicly funded research base, this is true of an alarmingly wide range of potentially useful, cheap therapies. It's also true of a lot of approaches to psychotherapy that can't attract the money thrown at CBT. CBT has been crowned without the essential competition.

    Alex Tsakiris has interviewed the cutting edge scientists and thinkers he claims in his Skeptiko podcast, but is far more inclusive and increasingly so of stuff that would press most people's crank button. What you describe as changing the topic is really nothing more than his guest's complete unfamiliarity with the research. People go on the show to promote their book, and when he offers a vying perspective they've rarely heard of the other perspective no matter how academically respectable. This - and the Skeptiko title - leads guests to claiming they've been bounced, when most were hoping to get an easy ride before a tame audience. Listening to the archive soon reveals a pattern of academics working in their individual silos and making bold claims, not least in the areas of consciousness studies, that don't bear scrutiny. This is not always easy listening.

    No romanesque, what is said about Alex Tsakiris is that he edits the interviews and changes the words of his interviewees in the transcripts as well as introducing the topics at short notice. That's not presenting ideas, that's changing the goal posts to show himself in a good light and others in a poor light.

    The book review suggests that he starts with a hypothesis and will accept anything, including a satire that refutes the hypothesis as evidence, to prove his idea.

    I don't believe that's the case for one minute, it sounds like materialist evangelicals muddying the waters. I've listened to most of the podcasts and the transcript matches the audio, given the voluntary nature of the transcription and the inevitable umms, arrs of discussion.

    The idea that he edits audio maliciously sounds like sceptical fantasy, there's no necessity for such monkey business when the guest hangs themselves so enthusiastically.

    Yes but also no. It is certainly true that Science follows a particular philosophy and that almost everyone has signed up to it to the extent that those who fall foul are named, shamed and excommunicated.

    At the same time, it is hard to call it an ideology when it boils down to "do your damn work openly and honestly". That's like saying that the civic expectation on a policeman to work honestly and fairly is an "ideology". Err..

    Well, "rule of law" is also an ideology. And science dictates not just "do your damn work" but also has rules for what counts as evidence, or "work" as you put it. Spectral evidence, for example, falls outside the realm of science, largely because it usually can't be reproduced or examined by anyone else. This may seem unfair to those who wish to rely on such methods, but you can't really do anything that can properly be called "science" without such standards.

    Actually there's a tremendous evidence base behind the use of aspirin, most of it paid for by the public purse. The UK government invests quite a lot in healthcare trials, all of it to advance treatments that wouldn't be supported by private funding. Similar things happen in the US.

    It is actually happening, it's not just an idealistic dream. It is probably true that mental health care, and especially psychological therapy, has been underfunded, but I think the reason for funding trials of CBT over other forms also relate to the fact that it is easier to write down what CBT is and to deliver it in a set time period. Other therapies that are harder to write down and neatly deliver are less attractive to a high throughput health service.

    The Higgs Boson is not the something "behind" the previous layer in the sense that I think you mean.

    Quarks would be a layer "behind" hadrons - in a nutshell, you could begin with the existence of protons and neutrons, move on to the discovery of other baryons, observe that they appear to have this property called isospin, and finally come to the quark model as an explanation for all of that.

    If you want something to be "behind" the existing standard model, you could look at superstring theories. String theorists, however, have a computational problem - they find it difficult to make predictions that are testable at attainable energies.

    What is the ultimate objective? A single theory that describes the universe. A theory that can include both gravity and quantum mechanics. A theory that can explain why the universe is matter-dominated. Understanding what dark matter, and dark energy, really are.

    Yes. We know that the bits close to us are matter. If there were regions of antimatter, we'd see annihilations at the boundaries. We don't see that.

    Is it possible that there are antimatter superclusters sufficiently well separated from their matter cousins? We can't quite rule that out, but nobody has a mechanism to produce it (and some reasonable arguments in support of it not happening.)

    It does rather depend on what you mean by "matter". Does it, for example, include energy that can transform into particles? Or, just as one side of an arbitrary line between "matter" and "antimatter"? How do you incorporate that we call the particles emitted in beta- decay an electron and antineutrino (conversely, beta+ decay emits an antielectron and neutrino and electron capture a neutrino) - would it make any difference to the argument about the dominance of "matter" if we had called the particle emitted in the more common decay mode the neutrino rather than antineutrino? Is the distinction between "matter" and "antimatter" significant? Or, is it just a particular naming convention for mutually annihilating particles, and "antimatter" is just another form of material particles?

    I'm confused. In what way is this line arbitrary? I was under the impression that if you mix matter and antimatter they react rather decisively with one another. That seems a pretty thick black line.

    The arbitrariness is in the nomenclature. There could be a decent argument to call an electron "matter" and positron "antimatter" on the basis that one is far more common than the other. But, why have it one way round or the other for neutrinos when the anti-neutrino is produced in the more common form of beta decay?

    Intelligent Design was part of this thread back from the start. There is a mention on page 1 - post 8 on this thread referring back to the mention of Behe in the opening post. In the first few posts, the argument was made that science and philosophy are looking at different aspects of the same problem. Intelligent Design is looking at the philosophy and the why, not the how that science considers.

    Yes, there are problems around the distortion of scientific research by the pharmaceutical industry in particular, as outlined in Bad Pharma and there are various campaigns pushing for all results to be published, particularly All Trials. There are issues with the funding of research and the distortions that can cause but that doesn't mean all science is made up or should be ignored.

    I'm too old and ugly to accept Rationalwiki as a value neutral window on the world. I don't happen to agree with Alex Tsakiris on any number of issues, but in the same way I don't hold the BBC in contempt for allowing terrorists and extreme nationalists to air their views as well as mainstream politicians, Tsakiris has interviewed some compelling voices outside the mainstream whose voices demand an answer.

    Similarly for the Discovery Institute, one doesn't have to be a young earth creationist to welcome debates on C19th scientific perspectives. There's a problem funding any research that fails to acknowledge an exclusively physicalist interpretation of reality, which inevitably places all challenges to it in the academic margins. That doesn't mean the topic at hand is marginal to the nature of reality. I reject "woo" is a barometer of anything except the prejudices of its user.

    In the case of Dean Radin, his research is concerned with the measurement problem of quantum physics and the implications of it for consciousness. When studying clear scientific inferences puts the researcher into the freakzone, the problem isn't with the hypothesis.

    That's the point, there isn't really anything. Positrons and electrons are both leptons, both have the same mass and spin, it's only their charge that makes them different. Neutrinos and antineutrinos have the same (zero) charge, spin and mass with opposite chirality and lepton number. Basically each particle comes in two almost identical forms - electrons and positrons are far more similar to each other than either is to a neutrino or proton. Given sufficient energy (and some other conditions) these particles can be created in matching pairs, and those pairs can convert back to energy when they collide.

    Well, the photon is its own antiparticle, and pair production will produce matter and antimatter in equal quantities. When I talk about matter here, I really mean fermions.

    quote:

    Actually, that's the same reason. A photon can produce particle-antiparticle pairs, or equivalently, a charged particle can emit a photon (it's the same process.) A W- boson can produce an electron and an electron antineutrino, or equivalently an electron can transform into an electron neutrino by emitting a W- boson.

    quote:

    The difference between "matter" and "antimatter" fermions is significant. You can't trade the neutrinos for the antineutrinos, for example.

    The left-handed electron and the (left-handed) electron neutrino form a doublet under the SU(2) symmetry of the weak interaction. In other words, a neutrino is "like" an electron because they transform into each other under SU(2) transformations. Physically, that means "emit a W boson".

    Photons aren't "matter". A photon is also an antiphoton, so it doesn't get to play for either team. When we talk about matter, we mean the fermions.

    But the protons and neutrons thing is interesting. In the current Standard Model, quarks and leptons don't couple. That means that there's no mechanism to connect the matter-ness of electrons and neutrinos with the matter-ness of up and down quarks, and so in the current SM, we make the arbitrary assertion that electrons are "matter" like up and down quarks (and hence protons and neutrons).

    In the unified theory that everyone thinks must exist, leptons and quarks are combined in an irreducible representation of the symmetry group of the unified theory (SU(5) is the smallest possible such symmetry group, although I think the non-observation of proton decay has pretty much ruled out all the SU(5) possibilities.) This combination places quarks and leptons in the same representation, and so ties the matter-ness of quarks and leptons together.

    That's what I was thinking of. In that view, aren't matter and energy flip sides of each other? Sort of like energy is matter dancing very fast, and matter is energy meditating? (Don't laugh too hard, please! [Biased] I've been using that comparison for a long time, and it makes sense to me.)

    When photons undergo pair production (which they do), they produce a particle and its antiparticle at the same time. So matter-ness is conserved: you start with a photon (no matter) and end with an electron and a positron, say (no net matter - a particle and its antiparticle).

    In order to generate a matter-filled universe from a big bang, you need a mechanism that produces matter from energy without producing antimatter at the same time.

    Or alternatively, you make equal amounts of matter and antimatter, and then have a mechanism to sweep all the matter over in one direction, and all the antimatter in the other direction, and leave a big gap in the middle.

    The former is easier to imagine than the latter.

    So why does 'matter' predominate? [Biased]

    I imagine in me complete ignorance that there was an imbalance in matter-antimatter creation, but to what degree and why how can one know?

    Any road up, I came here to muse on a conversation outside the public toilets at Wells-next-the-Sea on Saturday, in shadow of the terribly moving memorial to the 11 men drowned in the 1880 Eliza Adams lifeboat disaster, leaving 10 widows and 27 orphans, unmemorialized, in a small town.

    I was photographing Solanum nigrum (in the OPPOSITE direction to the front of the toilets ...), across the road from the tide monitoring station where the iridescent starlings roost, which is germane. A woman commented on the colours which she which 'you don't usually notice'. I repressed the impulse to hold forth on them not being due to pigmentation but to iridescence. Then I realised I couldn't explain the latter more deeply without opening up the Pandora's box of interference, phase shifting, thin-film interference and diffraction. I imagine in feathers it's thin-film interference. Or diffraction. Or both.

    An older chap like me came out the toilet and stood by me as I crouched by the flowers, 'A nightshade.' I said. He launched in to a little homily about looking at a butterfly 'the other day' and saying that it didn't have to be SO beautiful.

    I didn't get his agenda and said it was due to competition. He ignored me and said that it was excessively beautiful because it had a designer, 'God' and walked away as I said 'Maybe both'.

    What a typically depressing interaction.

    Particularly as I don't subscribe to ID in the slightest degree apart from in the original creation of this universe.

    In which there was a bias toward matter.

    It's 43 years since university so I have forgotten most of it, but if I remember correctly it would not need that great an imbalance between matter and anti-matter, then it snowballed.

    I am sure someone who is more up to date in their Astro-physics will now correct me.

    A less matter-centric view might be that matter doesn't predominate, empty space does. Non-matter, not matter nor anti-matter.

    Like life and death, matter and energy are actually the same thing. You just have to understand that our ideas of life and death, and matter and energy are products of our languages and thus metaphors at best. Symbolic representations of underlying reality.

    Plato told us thousands of years ago that we see shadows of reality reflected on the walls of the cave. We don't see actual reality. So when you think matter versus energy you're doing what I do:thinking in human terms. More easily (for me) consider 3 dimensions: then try to think of a 4th at right angles to those. Warps the mind, but it's on the track toward understanding. Similar also is particle-wave: light is both and neither. Sometimes it's useful to think of as one or the other, but these are merely metaphors not really approaching what it truly is. Because we haven't a concept for it.

    Well, yes. And, no. In certain circumstances matter and energy can exchange between each other - energy becoming matter, and matter becoming energy. But, that doesn't make them the same.

    At a very (with lots of other very's) early time in the universe the initial energy of the universe cooled sufficiently for it to transform into "matter" and "anti-matter" (both of which really are different forms of matter). There was a very (with lots of other very's) slight bias towards matter in that process, so that as that matter and anti-matter annihilated to produce photons (yet another form of matter) there was a little bit of matter left over, just enough to form stars and planets and galaxies .... and people like us to wonder about it all.

    The problem is that we don't know why there was that little bit of extra matter formed. We invoke "symmetry breaking", something where the properties of matter and anti-matter are very slightly asymmetric - mass, magnetic moments ... something. Though, we've yet to find any such asymmetry - within the last few days results have been published measuring the magnetic moment of anti-protons, identical to that of protons to 19 decimal places.
