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?

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.
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?
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?
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.
(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....
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 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.
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 ;-)

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.
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.
[link fixed (I think, it was a mess)]
[ 01 July 2001: Message edited by: Erin ]
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!
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."

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

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?

Perhaps while you do this you could explain why you think it is necessary to believe it?

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.

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?
Neil
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.

Timothy
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.

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.
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 )

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.
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.
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.

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...!

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?

2 Samuel 241 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 211 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?

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

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!
Couldn't we use Abram's journey as a paradigm here?
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.

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.

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.

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.
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.

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....".

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.
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.

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.

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.

Well I don't hold that view of scritpure, and even many of the Christians on this board don't (I think).
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

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?

Besides, what is wrong with theology incorporating good science?

But the broad picture of Darwinian evolution is so solidly founded that there is no danger there.
Alan
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.
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.
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.
Alan
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?
quote:

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.
Alan
quote:
'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.'
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
Neil
quote:
The philosophical positions...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.
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.

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)
Alan
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:
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.
Neil
Alan
quote:
commitment to ‘natural selection’ as the mechanism for the origin of species and the origin of life
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.
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....
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.
Alan
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.
Talk about disasters...

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?

Neil, I don't see the "why" in your definition of (neo-)Darwinism, in either its' scientific or philosophical forms
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?
Neil

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.

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.

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.
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.

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.

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?

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?
just a thought

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.
quote:
The one time that "Darwinism" oversteps its brief is when it is used as controlling metaphor for something that is not biology.
When it is used for a controlling metaphor it is no longer science but philosophy.
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'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.
Neil
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:
SirI 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?
Neil
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.
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:
Moreover, if God did, as I believe, use evolution as the outworking of His creative activity
In what sense are you defining 'evolution'? (1), (2) or (3)?
Neil
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.
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.
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.
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
PS...I'm leaving work now for a long weekend on a tropical island paradise just north of the equator. Snorkelling and sailing. It's a tough life. Speak to you Monday.
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
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
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.
quote:
What else was around last century to cause the crisis of identity if
it wasn't the effects of Darwinism?
well stephen j. gould says the first thing to cause a crisis was the concept of "deep time", ie that the world has been around a lot longer than the 6000 or so years recorded in the bible. and this concept predated darwin by a good bit (i forget how long) and has nothing to do with darwinism. except that it provides the span of time neccessary for darwins mechanisms to work.
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.

Our amazement at the greatest phenomena is not lessened because we have discovered the manner in which a certain one of the marvels occured.
Basil, Homily I
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.
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
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:
Why must science have a prior commitment to philosophical naturalism?
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?

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.

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

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.
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)).

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 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".
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
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:
quote:
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.
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.

PS After the account of your weekend, I'm now definitely jealous
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.
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.
In summary the whole issue of "information" raised by creationists is a huge red herring in my view.
[LIST]
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.
Willy
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?
Neil
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.
Thank you. I meant it as much more than an implication. Please note the opposite proposition is also true. You will never prove the non-existence of God by such research either.
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.

Could you restate this? I'm simply confused.

If your physicist and chemist friends were practicing good science, they would be as committed to methodological naturalism as any biologist.

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.
Neil Robbie:
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.
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....
All the best,

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.
quote:. 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.
"how" questions are not theological questions"
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:. 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.
to give the exact sequence of developmental steps in each of those pathways is impossible
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!
Neil
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?
quote:
Science should say to Joe Public, now, that 'we don't know 'how' it came into exisitence'.
That is exactly what it says. I think it is your science teachers and text books who may have it wrong, not the scientists.
quote:
We don?t know about 'how' information as distinct to matter came to be.
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.
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.

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.

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.

Philip Johnson seems to me to have a very limited understanding of what science is about but that doesn't stop him from talking about it as if it was the ultimate enemy.
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.
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.
I wonder which side of the philosophical fence he sits on!
John and Karl, it is not to provide a rival theory to Darwinism but to point out that the burden of proof currently rests with the theory to prove how the irreducible can be reduced.
And my point is not, now, to 'disprove' Darwinism, but for the media and schools to be honest about the problems with the theory.
'These are the observed facts of science…some of them cause great problems for Darwin's theories'.
Simple and honest
Which side are Christians on? A commitment to Darwinism or a commitment to truth?
Neil
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 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
quote:
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.
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.

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.
* most deep-sea/oceanic shipwrecks for instance contain no discernable human remains, though clothes may survive in a form suggesting the previous existence of a corpse in them; the bodies generally just dissolve away.
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:

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.
Neil
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.

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?

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:

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

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.

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

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.
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.

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
Is there a connection? We should be told!
quote:
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.
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 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"
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
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.
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
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..
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.
Neil
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
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.
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?
Neil
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!'
[edited for typo and to add bit I forgot because I can]
[ 17 July 2001: Message edited by: Karl ]
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.
Alan
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

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
Neil
quote:
What gives science this legitimacy?
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?
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?
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
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.
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
Karl, you said
quote:
Fascinating. And highly illustrative of the disingenuous way in which quotations can be used.
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
quote:
Gould said 'science, properly interpreted and used to empower all the people, might truly help us to be free (from God)'

'Grace' - genes which determine our position in society (this is Richard Lewontin's limited definition of grace in his book 'The Doctrine of DNA.
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 hadn't gone away I just occasionally remember to shut up if I can't think of anything useful to say.
Besides which I thought this belonged on another thread.
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).
Why "liberal humanism", whether or not that is a fair definition of its philosophy, is the ultimate enemy in the face of rampant Islam etc escapes me. But then I don't agree with much else you've said.
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.

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.
Please accept my apologies gentlemen.

PS. It's great to know someone else has 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.
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 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?
Neil
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.
Neil
quote:
Is this a valid position all theistic scientists can hold?
Yes
quote:
If it is, why don't theistic scientists hold this philosophy more strongly?
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.
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
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
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?)
Glenn
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.

Glenn Oldham:

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)
Willy
Nicely put.
It seems to me part of the tortures of purgatory to find oneself bombarded with many book recommendations!
You say,
quote:
Quantum materiae materietur marmota monax si marmota monax materiam possit materiari?
When I joined my secondary school in 1967 they had just scrapped compulsory Latin. Could you provide a translation!
Glenn
Willy
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.
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
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.

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.

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
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.
Neil
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.
P.S. not everyone agrees with Kuhn's take on science - not by a long chalk, though it is clearly influential.

Although Marx was a great admirer of Darwins rather fearsome intellect, and its fair to say that some of his thinking was influenced by evolutionary theory. He sent him a copy of Das Kapital as a token of his esteem.
Which was found, pages uncut, amongst Darwins effects after his death.
d.
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 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 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.
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).
Glenn
P.S. In your last post you credit me with a number of excellent comments which I think are actually from Alan Cresswell.
quote:
what is at stake is more than just a precious scientific theory, it is a whole way of thinking for society
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.
Does this mean you all agree that we are witnessing the start of a potential paradigm shift?
Neil

Philip Johnson agrees with you on that.

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.
Neil
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.

What are you talking about? What is non-Christian about relativity or quantum mechanics?
You are staring at a monitor attached to a computer which relies almost entirely for its operation on the "tunnel effect" - a quantum
mechanical notion.

He suggests that this is because, as to the the theory of evolution
quote:

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.
Glenn
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?
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.
Dark ages II here we come....
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.
Neil
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.
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.
Neil
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.

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.
Life on Earth is not random. Natural selection is not a random process.
It may still have no purpose though!
I'll quote myself first:

Neil
quote:

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".
quote:
"a way of viewing the results of methodical science into the way material objects function" Neil Robbie, 31 July 2001 00:13
Does it really matter what your view is? For example, if the "results of methodological science" indicates that the mass of an electron is 9.1×10¯³¹, does the electron "function" any different because of your "way of viewing"?
Exactly what it says.
Explanations that make no mention of, nor make any reference to, nor ascribe anything to, God, a god or gods. Or anything else supernatural.
i.e. scientific explanations.

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

Explanations that make no mention of, nor make any reference to, nor ascribe anything to, God, a god or gods. Or anything else supernatural.
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.

...erm, what do you mean by "viewing... inthe the way material objects function" - sounds like a philosophical view of a mechanistic process - is this what you intend?
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?
Glenn
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
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.
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.
Glenn
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.

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
Now back to the scheduled programme ...

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.
Alan
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:your statement was not clear as to whether the ‘explanations’ referred to functionality or origin.
Explanations that make no mention of, nor make any reference to, nor ascribe anything to, God, a god or gods. Or anything else supernatural.
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.
Neil
PS Cro?sos you asked
quote:
Does it really matter what your view is? For example, if the "results of methodological science" indicates that the mass of an electron is 9.1×10¯³¹, does the electron "function" any different because of your "way of viewing"?
Do you mean, “does it matter if you believe God exists?”
You said
quote:
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.
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
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.

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.
Neil
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.
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.
Glenn
You said
quote:
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.
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:? You seem to have excluded specification, in favour of random development, and in so doing you have excluded God.
'God intended us but did not design us.'
Neil
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.
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.
Alan

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).
Glenn
P.S. Behe's book Darwin's Black Box arrived yesterday and I am now reading it!
[UBB fixed to remove nested quotes]
[ 06 August 2001: Message edited by: Alan Cresswell ]
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?
Neil
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
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:Yes, this is what I have been trying to say, that anything beyond functionality is into the realms of philosophy (atheist or theist).
If that is the case then your formulation of Intelligent Design is inherently unscientific (meaning "outside the realm of science").
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: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.
the last time this world view prevailed was the Inquisition vs Galileo
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.

[ 07 August 2001: Message edited by: Alan Cresswell ]
I am tempted to conclude that there is no coincidence between your new thread
'picking and choosing scripture - why not - it's scriptural!' and my post regarding a Biblical Theology of the cross in response to your question about demonstrable evidence in science.
Are there any grounds to my suspicion?
Neil
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.
Glenn
PS.My hard drive is hiccuping so if I disappear for a while that's why.
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".
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'.

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
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").
Alan
I gather from what you said
quote:that you understand ID to involve miracles.
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.
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

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
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.

Alan
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: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.
Neil
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".
Alan
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?
Neil
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
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.
Neil
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.
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).
Alan
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’?
Neil
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.
Neil
quote:
Originally posted by Neil Robbie:

Which brings us to one of the points on your list,
quote: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.
- 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).
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"

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.
Neil
quote:
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,...
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.
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.

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.

Alan
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'.
Neil
You know from previous posts on Darwin and Neitzche that I have not been too hot on my dates (lack of attention in 'O' grade History).
The gist of your post is summarised when you said that
quote:
The lack of satisfying religious explanations for the world led them to investigate along other lines
In the context of your post the 'other lines' are scientific investigations. Is science the basis for your atheism?
Neil
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. But, no matter how much the likes of Dawkins may want it to be, evolution is not a philosophical position.…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.
Neil
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.
Neil
quote:
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.
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.

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.

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.)
Alan - The historical question of the origin of science is one of interest to me, but is only tangentially related to the current topic, which is cluttered enough without getting side-tracked. Because of this, I decided it would be best to "spin off" the topic into its own thread, Athens, Jerusalem, and Science.
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 am sorry. I promise to do better Historical research for future posts, should I refer to dates again.
On your answer to my closed question, good, science is no basis for faith. But you're not giving much away. Why do you believe that God does not exist?
Neil
Alan
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.
So Dembski's position is philosophical rather than scientific?
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.
Alan
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?
Neil
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.
Alan
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?
Neil
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.
Alan
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 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?"
Going back to the post you mentioned on the 14th August, you said
quote:
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?
Neil
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?

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?
Neil
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.

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.
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.

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.
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.
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.
quote:tees it up nicely.
And finally because a lot of Christians misidentify the Theory of Evolution as their enemy.
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'.
Neil
The BBC article demonstrates that this is not about 'evolution' or any other beloved theory, it is about legitimacy amoungst the intellectual elite.
Neil
This is not helped by attacks on science, whether they come from Michael Behe or from Duane Gish.
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.

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...

the unguided, random, purposeless development of all life on earth
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.
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.
Neil
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)

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.
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!
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: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
races are naturally and essentially different, race is a fact, it is everything.
quote:and that this was a disturbing but real conclusion Darwin faced.
'at some period in the future the civilised races would exterminate the savage races'
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

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 have re-read that post and I quote from it:
quote:
Joe Public has no way of questioning Lewontin's philosophy because, as Lewontin pointed out, no one understands his science.
now who's being patronising?
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
quote:

How will the church, indeed all of western culture, achieve liberation from such firmly binding shackles?
Neil
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'.
?
Neil
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.
Neil
I agree with lots of this, but not (as currently phrased) to your dislike of objectivity.

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) ?

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.
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?
quote:
You seem to be saying that there is no objectivity possible.
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?
quote:

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.
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
Neil

What is in conflict is the thought that 'evolution' is a chance process, that random mutation is not part of God's natural process or nature, that it is all down to pure luck or survival of the fittest, latent deism. But the 'natural' events of evolution are to be seen by the theist as part of God's action in creation, that is, they occur according to his nature.

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.

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?

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.
Neil
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.

What a blunder...there is of course no prohibition of empiricism under theism.
Would an administrator mind, please, adding 'not' prior to the word 'prohibited' in my previous post?

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

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 ?
Russ
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:
quote:
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.
... since I think that secular government and the separation of church and state is vitally important for the health of society and we Christians should support it.
Glenn
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.

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.
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
PS: should this go on a new thread? we seem to have drifted away from Darwinism...
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.

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.
Glenn
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.

Glenn
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!

Good idea. I'll start up a new thread on objective/subjective. See you there.
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
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

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?

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,

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.

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.

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.

Not so fast, Monsieur Robbie, not so fast...
I think we're entitled to know what the gaps are, aren't we?
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.

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.

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!
Glenn
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.

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.

A few weeks ago in New Scientist (I can't post a link as it's in the pay-to-view archive now) someone wrote an article in which he stated that his research had forever banished the theory of Intelligent Design of life.
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.

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.

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.

It's no more valid to criticise Darwinism for this than say criticise Special Relativity because you disagree with notions of relative morality.
The playwright blamed the doctrine of survival of the fittest for ‘capitalist misery and the oppression of the people’.

I also did not feel comfortable learning about the periods of time of the Jurassic etc
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.

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.)

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.

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.
the other thing about dating the way I see it is that the concept is to extrapolate - and base it on an imagined amount in the first place.
quote: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.

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.

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.

Natural selection is an exchange of information (via genes) that results in loss 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.
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.
quote: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).
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.

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: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.
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.

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.
I would like to see the irrefutable evidence that the universe is millions of years old.
quote: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.
I can show you studies where living snails have been carbon dated at thousands of years old.

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?
quote: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 ...

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.

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.
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.
quote: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).
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.
quote: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.

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.

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
quote: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.
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. "

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.
quote:No, it isn't. Can you explain the fossil distribution within the sedimentary layers using a flood model? Can you explain how volcanic intrusions exist within these layers? How this flood preserved the tracks and burrows of land animals? How it even preserves desert palaeosols?
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
quote: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.
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.

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

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.

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).

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 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.

ken said:
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.
quote: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”.

Your fitness is how many grandchildren you have. People with more grandchildren have more grandchildren then people with fewer.

So Darwinism can certainly be interpreted to be consistent with philosophical naturalism, a most reassuring conclusion for atheists, but troubling for believers.

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.
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.

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.

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.

quote: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?
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.

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.
quote: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.
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.

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.

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!

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.
quote: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).
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.

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.
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.

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.

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.

The argument is that in some cases apparently homologous features are controlled by different gene sets, contrary to what one would expect;

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)
in other cases the homologous structures are not seen in embryonic form, but develop later on through very different developmental routes;
quote:Yes, and its very interesting, but hardly relevant to this discussion.
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: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.
A feature in two or more taxa is homologous when it is derived from the same (or a corresponding) feature of their common ancestor.

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."

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.

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. 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.

That, in a rather over simple way, is how random mutation plus natural selection plus replication provides information to the evolving organism.

It is an entirely plausible and respectable scientific viewpoint to believe that the method of evolution which is purported to have happened from primordial sludge to a mitochondrion is extremely unlikely and not a very logical theory. There are many reasons for this and I'm sure they've been discussed in the dead horses thread - I'll reiterate them there if anyone isn't familiar with them.

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.
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.

quote: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.

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.
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.
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.
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.
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.

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.

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.

My point about chess was that human

It is an entirely plausible and respectable scientific viewpoint to believe that the method of evolution which is purported to have happened from primordial sludge to a mitochondrion is extremely unlikely and not a very logical theory.

My belief in ID doesn't come from any theological objection to the origins of life as popularly understood (or from an 'objection to Darwinism'), it comes from an understanding of molecular biology.
Can you suggest ways in which ID could be empirically falsifiable? What experiments could one do? What research programme might find data to refute it? Given that the existence of a deity is a metaphysical hypothesis, is not the basis for ID conveniently placed outside the realm of refutation? And if so, how can it claim to be scientific.

In other words, Dawkins’ simulation knows where it wants to go right at the start. By maintaining the correct letters as they appear, Dawkins also ensures that his simulation can only change consistently in one direction - it can never be stable or cyclical. Not surprisingly, his simulation converges very quickly to the desired goal of a meaningful phrase. It is most definitely not a model of an unintelligent and undirected process (“natural selection”).

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.

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?

(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.)
quote: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.

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?

quote:the same abstract on pub med
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.

quote: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.
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.
quote: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.

quote:Science needs to be used for evolution and theology to argue with creationists. Your point?
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.
quote:Then please explain in what sense the giraffe's nerves going 5m out of their way is anything like optimal under any scale. Please explain how tonsils or the appendix (or any other vestigial organ) are optimal.
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.
quote:We don't need many cases. One would be enough.
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”.
quote: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.
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.
quote: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.
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.

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'?

quote: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.

1. If p is an instance of organic design, then p was produced either by a wise creator, or by descent with modification (evolution).

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.
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: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:
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.
quote: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?
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?
quote:True of course, but incapable of distinguishing special creation from evolution, because it applies equally to both.

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.

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 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.
quote: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.
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.

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.

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.
quote: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.
Glenn Oldham said:
I am not entirely sure what relevance your point has to the question of whether this invalidates the experiment's analogousness 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.

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.
quote: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.
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.

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.)

quote: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.
Glenn Oldham said:

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.
quote: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.
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.

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.

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.
"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]

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.

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.
quote:In the light of these comments let’s look more closely at how the experiment operated:
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.
quote:So, we are both agreed that these algorithms have access to an “ideal” at all times – the specified end goal.
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.
quote:And goes on to conclude, with their original emphasis:
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.
quote: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.
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?

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.
…
… 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, … 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.
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.

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.
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.

There is definitely no purpose to natural selection. Any form of teleology is completely out. We are an accident of nature.
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.

Glenn Oldham said:
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.
quote: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.
Glenn Oldham said:
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: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.

quote: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.
Glenn Oldham said:
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.
quote: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.
Glenn Oldham said:
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:
quote: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.
“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”.
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.
Glenn Oldham said:
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.
quote: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”.
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.
quote: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.)
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,
quote: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.
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.
quote: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.
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.

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.

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.
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. 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.
” a more accurate phrase in relation to the source of the final configuration would be “pre-existing information found through an efficient search pattern”.”
quote: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.
Glenn Oldham said:
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.
quote: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.
But natural selection doesn’t choose genes directly, it chooses the effects that genes have on bodies, technically called phenotypic effects.
quote: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.
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.
quote: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.
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.
quote: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..
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: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.
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.
quote: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.
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.
quote: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:
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.
quote:(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.)
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.
quote:In comparison with this, we have already seen how Richard Dawkins describes natural selection on page 50 of The Blind Watchmaker:
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.
quote:and Dawkins goes on to say on pages 61 and 62 of “The Blind Watchmaker”, immediately after the section on biomorphs:
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.
quote: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.
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.
quote: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?
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)
quote:which perhaps goes to far in using the words "consistent" and "predictably".
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.
quote: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.

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. )

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.
quote: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”.

quote:you replied:
a more accurate phrase in relation to the source of the final configuration would be “pre-existing information found through an efficient search pattern”.
quote: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.
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.
quote: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.
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.

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?

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.

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.

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 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.

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:

...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.

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.

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.

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.

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.

So for those who believe you came from an ape, God Bless you and we'll just have to agree to disagree. I can see your problem with the whole perfect couple, lack of a specific time of receiving a sinful nature if you take that stance. But the bible (in case you can't tell im protestant and take most in fact pretty much all of the bible to be literal) says that God created us in His image. This is so we can communicate with him to have a relationship with him, so if you believe in Evolution then you have to accept a point where God changed us from animal to his image.

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.

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,
quote:First, the stars in Orions belt are too far apart to be directly held together by gravity (though they do, like all stars, contribute to the general gravitational field of the galaxy and so do indirectly held each other together). 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?"
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.
quote: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.
All the prophecys are exact in timing, from Christ entering jerusalem, to Isreal becoming a country in 1945.
quote: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.
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.
quote: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.
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.
quote: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).
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.
quote: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.

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: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?
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.
quote:Some mutations are deleterious. The vast majority are neutral. A small proportion convey some advantage.
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.
quote: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?
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".
quote: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?
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.
quote: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?
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.
quote: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.
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.
quote: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.
Mutations generally can not.
quote: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.
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.
quote:No, they change when that happens. Ecosystems evolve along with the organisms within them.
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.
quote: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....
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.
quote:I'm sure we've been doing it for tens of thousands of years.
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.
quote: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?
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.

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.

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.
quote: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.

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.

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?

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.

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.
quote: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.

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.

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.
quote:You mean by having a 17 page thread on "The Death of Darwinism"?
Now this is very far from this debate I realise, but my point is this - why do we trust our scientists so much?
quote:The reason scientists and science are looked to is that they work better than any of the alternatives.
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.
quote:A very good point.
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.

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.
quote:And here starts one of my rants about current scientific education.
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
quote:Fluid dynamics is absolutely foul to calculate. (I speak from experience)
- 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.
quote:Try looking up the math sometime. It's not pretty.
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.
quote:See other answers.
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.
quote:Science needs to be much better taught. Your point?
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.

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.

quote: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.

quote: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.
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.

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.

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)

quote: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.
However, out of that enormous prestige has developed a scientific priesthood in positions of power and influence, whose pronouncements are treated as truly prophetic and almost godlike. Like all privileged priesthoods, those in positions of power and influence wish to continue in office – the perks are good and the glory is addictive.
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.
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". 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.
quote: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.
Rex Monday said:
They [ID ideas] are only debated within the narrow scope of ID supporters (who frequently exclude input from their critics). ID is neither exceptionally broad, nor does it have any particular approach. That's one of the very annoying things about it - it claims to be scientific but lacks a theory, does no research and has no predicative power.
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.
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.
quote: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.
quote: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.
Rex Monday said:
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.
quote: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.
quote: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.
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).
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.

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).

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:
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: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.
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).
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.

quote: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.

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? Quantum 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.

Rex Monday said:
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.
quote: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.

Rex Monday said:
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.
quote: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.
Rex Monday said:
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.
quote: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.
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.
quote: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.

“Selection” is therefore a complete misnomer and I would argue that it is being used in a very misleading way by Darwinists.

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.
quote:Here’s what EAM is:
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.
quote: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:
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.
quote:Please also note this comment from the ISCID article:
EAM is a process that involves non-mechanical, non-physical, phenomena, such as self-awareness, cellular intelligence, memory, intention, and other aspects of 'mind'.
quote: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:
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.
quote: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.
”The new data show that if more mutations show up at a gene, that gene tends to accept a higher percentage of those mutations.”
quote: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.
Callan said:

Callan said:
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.
quote:My point about Mass extinction was in response to this sort of argument, from the link already posted.
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: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.
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.
quote: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.
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: [snipped]
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.
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.
quote: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?
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.
quote:Nope, thought not. That is, AFAICS, what Lamarck argued. Where would you say that EAM differs from Lamarckism?
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.
quote: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.
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 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
quote: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.
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.
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?
quote: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.
One could of course turn this argument on its head and ask why should I trust anything scientific produced by those who openly espouse the agenda of secular humanism and/or aggressive atheism. This argument cuts both ways, but it is frankly an ad hominem and therefore a logical fallacy. Even Richard Dawkins may publish some truthful scientific research.

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.

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.
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.

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.
Rex Monday said:
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.
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.
quote:You don't define 'active', though. The world is full of examples where selection takes place without the intervention of some external mind, such way different sizes of pebble are sorted in a river bed. 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: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.
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.
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.
quote: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?
“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.
quote: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?
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.
quote: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.
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: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: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.
Rex Monday said:
How might you distinguish between the acts of an unknown and unknowable designer, and the workings of purely natural laws?)
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.
quote: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.
The “working of purely natural laws” is also a question begging phrase, given what I said earlier about the slipperiness of the word natural.
quote:Such as?
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.

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.

quote: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.

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.

I must thank you for illustrating my point so adequately. Most of your arguments are entirely ad hominem: Davison is writing science fiction; Remine is diving under umbrellas; and the EAM crowd are writing English literature. Need I say more?

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: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.
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.

You'll pardon me if I stick with Mr Competent.
As far as I know, the Wedge Strategy document is genuine, but do not mistake a public relations strategy for the substantial scientific issues underlying the debate. In a post-modern era it is easy to assume that style is everything and substance nothing, but try telling that to your plumber next time you get a leak, and even more when you have to pay him.

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.
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.

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.
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.

Dembski's article about ID in the Oxford Handbook of Religion and Science makes his own position crystal clear
quote: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...
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.

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 hoping that my query to Karl L-B would have attracted a more substantial response that might have have helped to elucidate understanding - "scientific frame of reference" was a lovely question-begging phrase that goes to the heart of the issue.
You may wish to think in detail about how you in your own terminology diffentiate between the "natural" and the "supernatural", and on what basis you arrive at this distinction.
quote: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.
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.

(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.

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?

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.
quote:Agreed - and I stand by my comment.
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.
quote:Agreed - but I note that there is nothing illegal, immoral, unethical or underhand per se about a PR strategy.
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.
quote: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.
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.
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).
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.
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.
quote:I am not even sure what your point is, so it is no surprise if it remains unanswered. Callan and Karl can happily speak for themselves.
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.
quote:No argument from me against the general concept of Popperian falsibility.
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.
quote:
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.
quote:I think that I have answered your question above. Others may wish to discuss the Wedge Strategy document, but I do not. I will stick with the fundamental scientific issues.
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?
quote: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.

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.
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"

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 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.

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”.
quote: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.
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?
quote:(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.
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…”
quote: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.
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? – 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.
quote: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.
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.
quote: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.

What on earth is Dembski saying?
I think to begin with you need to understand properly what Dembski is saying in relation to design and its detection.
quote:A rigorous mathematical fashion that doesn't work. Nobody in ID has ever been able to identify design rigorously, and claims that they have have been swiftly dismissed by finding concrete counterexamples.
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.
quote:Does he misrepresent himself when he says that he is codifying the theology of the Logos from John?
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.
quote:Dembski sees evidence for theism in his work!
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.
quote: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.
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:By contrast, Dembski's own equation deals with the probability of achieving an irreducibly complex system originating by Darwinian means.
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.

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.

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.
quote: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, 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)

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.
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.
quote: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.

quote: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).

quote:Last summer there was much previous discussion on this thread about genetic algorithms, but I don’t want to repeat it all. Start on page 11 of this thread and work onwards for several pages to see my views, particularly in respect to a certain electronics experiment that used a genetic algorithm. Genetic algorithms are a neat mathematical technique that demonstrates the importance of intelligence, purpose and design for them to work properly.
Sleepyhead said:
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?
quote: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.
Sleepyhead said:
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.
quote:That’s an interesting line of argument that I have not heard before. Apart from board games, what other areas of human design activity have you measured it against?
Sleepyhead said:
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.
quote: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.
Sleepyhead said:
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.

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.

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.

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.

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.

If you want to call "has on average at least one child that survives to reproduce per adult member of the species" as teological, so be it.
If you don't, then that is a non-teological process that provides a discernable criterion for success (if the average reproduction rate drops below this level long term, then the species is going to die out).

The idea that there needs to be intelligence to implement the above condition for success is NOT NECESSARY.
A species (or even an organism) that reproduces at or above the replacement rate in the long term is a success. One that does not is a failure. The search space is defined by the real world (which is affected by all the organisms living in it).
Now tell me what the above requires some guiding intelligence for.
A genetic algorithm simply takes the above and replaces the "reproduce at or above the replacement rate" with some condition specified by a designer (that will then reproduce the successes) and limits the search space. Same thing as done by any animal breeder.
quote: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.

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.
No one denies that ‘natural selection’ kills of individuals. The key question is what kind of genetic creative power it has in conjunction with random mutation, in the absence of any natural teleology.

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.

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.

This kind of loose language has a long history on the part of Darwinian apologists, starting of course with Darwin himself.

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.

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?

quote:Find me the point where a new structure can be said to exist...
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?
quote: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.
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.
quote:Why??? Absolutely no one else here sees any need or desire for that to happen at all.
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.
quote:Nor is anyone else. No one else thinks it happens that way at all.
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.

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.

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?
quote: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.
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.
quote:Ask your visual cortex.
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?
quote: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.
Yes, everyone uses computer simulations these days, but the point I have made about digital fiction needs to be borne in mind. 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.

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”.

quote: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.
Rex Monday asked:
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?
quote: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.
Rex Monday asked:
That's what it was intended to show. Are you saying that Avida's flaws are that it works?
quote: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.
Rex Monday said:
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).

Guesswork and speculative thought certainly have their place in asking questions, proposing a hypothesis and formulating a research strategy.

A working computer simulation that embodies certain starting assumptions cannot be cited as evidence for the truth of those assumptions. That is a circular argument.
quote: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.
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?
quote: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.
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?
quote: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.
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?
quote: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.
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?
quote: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.
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?
quote:Well, we clearly disagree over what constitutes evidence in support of a scientific theory, but at least you have moved away from the scatter-gunning of ‘creationist’ all over your posts. For that, at least, I am grateful.
Rex Monday said:
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.
quote: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.

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?

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.
quote:How on earth does gradualist evolution from less complexity driven by beneficial mutation show irreducible complexity? You've just described normal evolutionary processes!
(repetition of Avida description removed)
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 .
quote: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."
quote: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.
Rex Monday said:
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.
quote:Er..
Rex Monday said:
quote: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.
I may have missed some definitions, of course. Which of the various ideas in ID do you think are immune to Avida?
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.

quote: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.
Rex Monday said:
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.
quote: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.
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.
quote: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.
Rex Monday said:
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: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.
Rex Monday said:
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.
quote:“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.
Rex Monday said:
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.
quote: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”.
quote:Rex Monday said:
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?
quote: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.
quote:Rex Monday said:

How on earth does gradualist evolution from less complexity driven by beneficial mutation show irreducible complexity? You've just described normal evolutionary processes!
quote: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.
Rex Monday said:
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! ."
quote: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.

They "intend" to form a biofilm, signal each other that they are present in sufficient numbers, and they then go about making a biofilm, intentionally designing the film and coordinating their activities by intent and not by mechanical feedback mechanisms of the signal molecules phosphorylating receptors and so on?
How could you separate this from cold air and hot air "intending" to form a cloud and rain on plants so that they will give off moisture and present the cold and hot air with an opportunity to make more rain if they decide they want to?
I would guess that if you can find intent, broadly speaking, in bacteria you could find it everywhere. Bicycles develop a dislike for their owners, cause the owners to forget to lock them up, display their pretty colors to humans, and attract a new owner. It was not the intent of the human to steal, but the intent of the bike to be stolen.

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.
quote: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.
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.
quote: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.
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.
quote: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.
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.
quote: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?

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 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.

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.
quote:Your explanation is somewhat caricatured. The intelligence in question (to my eyes) appears to be an emergent property of the colony, not the possession of an individual bacterium. As for the mechanism of bacterial resistance, there appears to be a measurable increase in their rate of genetic mutation under antibiotic threat. What does that signify?
Originally posted by Cheesy*:
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.

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).
quote: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.
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.
- 'Ether dragging', which was intellectually unsatisfying.
- Special relativity, which was plainly bonkers.

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.
quote: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.
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.
quote: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.
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?
quote: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.

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.

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.
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.

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.
quote:“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.
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.
quote: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.
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.
quote: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.
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.

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: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.
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.

quote: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?
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.”

quote: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.

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.
That evolution by natural selection happens is (as I understand it) demonstrable in the laboratory (eg. in fruit flies). That's science.

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.

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.

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.

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.

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.
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.
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: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.
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.
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? 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.
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.
quote:Which ones, in particular?
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: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.
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?
quote:He certainly looked foolish in the courtroom.
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:There most certainly is such a thing as bad publicity!
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: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.
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.
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.
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: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.
The publishers of that book were forbidden by the judge from giving evidence in the court, so the full story could not be given.
quote:Really? Which parts of the book differed from that, then?
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.
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.
A policy of compulsion was a foolish mistake in political terms.
quote:Peer reviewed, eh? Tell me, what is the mechanism for peer review of a book? Which organisation was responsible?
[Dembski's] 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:
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.
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.
I believe that the Discovery Institute described him as an “activist judge” with “delusions of grandeur”.
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.
...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: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.

The big question is, will it be a minority viewpoint in the west of the future?
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.

His forthcoming follow-up book may also shed some light on this.

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.

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?

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.

quote: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:
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.

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.

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.
Originally posted by Rex Monday, citing the BSW:
Contrary to typical editorial practices, the paper was published without review by any associate editor; Sternberg handled the entire review process.
quote: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.
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]."
quote: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.

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.
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.

quote: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.
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.

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.

quote: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.
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.

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.

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).

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.
Neil
quote: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.
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.

If ID does advance, it will not be from sermons, but from science.

A genuinely new idea, even if it's completely against orthodoxy, will always get a hearing.

Another dilemma facing ID is the reflexive reaction against creationism (by a wide variety of groups/people/etc).

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.
quote: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.
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.

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.

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.
You will find more testable predictions from ID theory if you go looking.

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.

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.

Genetic algorithms are used in machine learning* to FIND solutions to problems. In most cases in my field where genetic algorithms are applied, we don't KNOW the target. If we did, we could program that in - presto, working application.
What you do know is how far from the target you are - an error measure. In genetic algorithm (GA) terms, you have a fitness function. Sure, you have to pre-code a fitness function, or an error measure. Is my error measure going to be number of pixels incorrectly labelled in this picture? Or an even less informative measure like how much positive reinforcement the robot received over its "lifetime"?
I grant you, that's a decision the designer makes. The point is this is NOT AT ALL the same as programming in the final (or initial) design.
So, yes, in any genetic algorithm, the program is written by a human designer, and the fitness function chosen by a human designer. But the outcome of the program is not under control of the designer once it starts. And, interestingly, I have never heard a machine learning research claim: "I found these parameters for problem X." The claim is : "My algorithm found these parameters for problem X."
My credentials? I am a machine learning/artificial intelligence researcher. I have not programmed a GA specifically, but could in an evening or two (and might for an upcoming project).
*Machine learning is a branch of artificial intelligence research that looks for adaptive programs rather than fixed (or hard-coded) programs.

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.

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."

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."

They aren't hugely complex chemicals, but they are a lot more intricate than salty water. Some of them are detectable in interstellar gas clouds, so, relatively complex as they are, they are clearly not that difficult to form.
Moreover, they are capable of chemically latching on to one another, in ways that the molecules and ions in salt and water aren't, to form polymer chains.

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.

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.

quote: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.

"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".

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.

I'd suggest that there appear to be two large gaps in your research. One would be filled by getting hold of some decent introductory texts for geology and biology; you seem smart enough that something aimed at first year undergraduate students in these subjects wouldn't be beyond you, otherwise there are some excellent popular science books around that are a bit more readable.

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.
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.

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.

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.

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

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.

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."

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.

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.

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.

Consequently, all their heirs and successors have mutation B. Although the mutations are random, their selection and propagation isn't.

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?
quote: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 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?

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?

Denying that those clues are there is roughly akin to doubting the Word of God, ISTM.

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.

Well It is certainly not about Science for me as I am all at sea there.
I am interested in the nature of the discussion though. Given that on both side of the debate nothing is replicable and only inductive thinking can be used, it seems to me to come down to a "It is..It isn't!" slanging match with each set of proponents having huge agenda that drives the debate.
In the Kitzmiller vs Dover case, the judge seems to have ruled against Behe's testimony on the basis that he had ignored scientific peer reviewed articles that dealt with the issues he was called as an expert witness on. Behe in turn seems to have claimed that those articles did not create convincing proof that evolutionary mechanisms could account for what he calls systems of irreducible complexity in his field of biochemistry. If I have misrepresented what happened in essence please correct me, I haven't done more than a bit of googling on it.
As to why I find Behe convincing. Well, I just read the book. (10 years after everyone else). While the arguments from analogy can never be seen as proof, and Behe himself leaves the door open a fraction to accommodate future science, I found his description of the blood clotting scenario very convincing. And latterly, the maelstrom of flying feathers that was the reaction, really a kind of affirmation. It is clear that the whole scientific community has such a stake in evolution being true, that whether it is true in fact has become irrelevant.
It is interesting that Behe has not backed down and is prepared to defend his views against the likes of Miller and Shanks and Joplin who have challenged him on the point that not all biological systems are irreducibly complex. Behe concedes that there is such a think as redundant complexity in which systems may at times function with a bit missing, but he sticks to his guns in the main on the sytems he claims are irreducibly complex.
Really, one is either for or agin his views and theologically prejudiced, which of course, I am.
quote: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.

I am interested in the nature of the discussion though. Given that on both side of the debate nothing is replicable and only inductive thinking can be used, it seems to me to come down to a "It is..It isn't!" slanging match with each set of proponents having huge agenda that drives the debate.
In the Kitzmiller vs Dover case, the judge seems to have ruled against Behe's testimony on the basis that he had ignored scientific peer reviewed articles that dealt with the issues he was called as an expert witness on. Behe in turn seems to have claimed that those articles did not create convincing proof that evolutionary mechanisms could account for what he calls systems of irreducible complexity in his field of biochemistry. If I have misrepresented what happened in essence please correct me, I haven't done more than a bit of googling on it.
As to why I find Behe convincing. Well, I just read the book. (10 years after everyone else). While the arguments from analogy can never be seen as proof, and Behe himself leaves the door open a fraction to accommodate future science, I found his description of the blood clotting scenario very convincing. And latterly, the maelstrom of flying feathers that was the reaction, really a kind of affirmation. It is clear that the whole scientific community has such a stake in evolution being true, that whether it is true in fact has become irrelevant.
It is interesting that Behe has not backed down and is prepared to defend his views against the likes of Miller and Shanks and Joplin who have challenged him on the point that not all biological systems are irreducibly complex. Behe concedes that there is such a think as redundant complexity in which systems may at times function with a bit missing, but he sticks to his guns in the main on the sytems he claims are irreducibly complex.
Really, one is either for or agin his views and theologically prejudiced, which of course, I am.

genetic mechanisms that produce variation are designed and are not products of Darwinian evolution.

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.
Furthermore, this variation--often called microevolution--has clear limits and is unable to produce macroevolution.
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: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.
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.

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.

What I wonder is whether there are a whole lot of closet flood geologists or doubters of evolution out there but they don't fancy becoming academic road kill by coming out. For some of them we're talking livelihoods after all. Arber is a case in point perhaps though I have not read him in detail. His work has shown up something creationists pick up on and he has been quick to deny creationist implications of his work, but really, perhaps there are some. The sacred cow of evolutionary progression is pretty well academically sacrosanct in most institutions wouldn't you think?

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.

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.)

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.
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.

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).

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.

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.

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.
quote: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.

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.

Small differences in initial conditions (such as those due to rounding errors in numerical computation) yield widely diverging outcomes for chaotic systems, rendering long-term prediction impossible in general.[1] This happens even though these systems are deterministic, meaning that their future behavior is fully determined by their initial conditions, with no random elements involved.[2] In other words, the deterministic nature of these systems does not make them predictable.

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.

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."

Hardly surprising that both Conway Morris and Behe cite the results to support their own divergent views on evolution.
quote: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.
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.
quote: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?

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.
quote:The other way round. The evidence is that successful adaptations are incredibly likely. Just look at the numbers.
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.
quote:And why would you expect to see that after only twenty years?
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.
quote:It makes the kind of evolution we see in the world around us seem even easier and more likely than we used to think it was.
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.

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.

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.

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'.
...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.

He is simply applying that principle to the 'software' in the cell.

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?

Whatever interpretation we put on it - and whatever interpretations have been handed down to us - are just more people (men usually) giving their take on the writing of other men.
To imply, however obliquely, that the most recent persecutions of the jews are all part of 'God's plan' is appalling and grotesque.

quote: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.
'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?

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.

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?

quote: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.

quote: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.

You would also, I think, like most here, see the Bible as written by men and therefore error and contradiction prone?

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?

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.

... if evolution is true it is unlikely our stubbornness, pride and cruelty would have been positive traits in 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.

There is no scientific basis for saying that the rocks lie. I couldn't care less on who believes what, that is no authority for me unless it is based on science.
quote: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.

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.

quote: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.
Originally posted by Martin60:
Do you mean that the C14 in the environment of (and including?) the AMS, without sample, gives a baseline background of 80,000 years?
quote: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.

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.

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.

Parapsychology is an amazing phenomenon in that only believers ever see positive results and those results are "mysteriously" never replicable when anyone else is looking.
It is, ironically, subject to the very fault you accuse science of. Beginning with a belief and accepting only that which enforces it.

Parapsychology is wishful thinking, for all intents and purposes, until verifiable results are demonstrated.
Morphic resonance is an idea with insufficient evidence.
All this would suggest that Sheldrake is questionable in his assertions relating to scientific methods, and, since he appears to be the base of your assertions, it is reasonable to question those as well.
Darwinism is accepted by a myriad of scientists who belong to a myriad of faiths. Christianity, Judaism, Buddhism, Hinduism, etc. Likely because they understand that faith and science are separate things.

quote: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.

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.

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.
quote: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.

quote: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.

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.

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?
quote: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.

I believe Meyer was involved in the publication of Of Pandas and People, though I don't think it was that particular edition.

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".

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.

quote: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.

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.

quote: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.

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.

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.

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?
