Yeah, I saw and read that.  I'm not sure what to say about it, though . . . It seems a bit strange to me that she did that, personally.

Anyway, the book is definitely interesting (due to all the fun examples), even if you don't fully agree with him.

I feel the root lays with belief instead of recognizing the hard efforts that have gone into testing various ways life has and continues to evolve. Listening to various members it certainly appears they favor a non material perspective. I also think those same members are sympathetic if not outright agreeable to parts of "The Wedge Document", specifically this part from post 435.

 Governing Goals
  • To defeat scientific materialism and its destructive moral, cultural and political legacies.

  • To replace materialistic explanations with  immaterial explanations and spiritual possibly theistic understanding that nature and human beings are created by God. 
    I've done some editorializing to the second line.

Agreed, Typoz. I said in an earlier  post that I learned a lot from reading those threads but the worldview of those involved in the debate clearly played a part, as mine does when I look at the evidence. Once again I'll say without hesitation that my idealism makes it much easier for me to accept that mind is omnipresent and therefore intimately involved in the evolutionary process. So if it is a choice of thinking, well that complex eye or that bird's feather could have evolved according to some teleological purpose or, in tiny steps, by waiting for chance to provide the right mutation and relying on survival advantage to adopt that mutation, then I am inclined to go with the former. This is even more so for me when I consider the origin of life and the appearance of DNA. Yes, the sheer complexity of DNA and the elegant choreography of what happens in a single cell beggars belief unless some kind of intelligence is involved. 

Epigenetics seems to be a step in the right direction except that those who propose it still seem to insist on a blind and purposeless process. Epigenetics, as proposed, is still missing mind.

Actually, I might be less than accurate in that statement. Danis Noble, for example, seems to favour teleology rather than "blind and purposeless" but he seems to hope to side-step the usual understanding of teleology by claiming that the teleology in evolution somehow emerged from evolution. Seems like a bit of circular reasoning to me - perhaps in order to deflect the outrage of those who might charge him with being open to a design argument.

Quote:What do we mean by “teleology” if not the tendency of a system to move towards the function that serves its interests in the organism as a whole, i.e., to have a goal? As I will argue later in this Dialogue, that does not require us to believe that there was a creator that designed the cardiac pacemaker. The term “final cause” has unfortunately created the impression that there is some ultimate goal in the universe from which all other forms of teleology derive. By contrast it is sufficient in my view to see teleological behavior as emergent during evolution.

Quote:Interviewer
 
 First, do you see teleology as objectively there in organisms themselves, or as a kind of illusion projected onto organisms by us? Doesn’t cybernetic theory, together with evolutionary theory (as delineated by Harvard ornithologist and philosopher Ernst Mayr [1904–2005] and others), obviate the need for us to take the apparent teleology in living things at face value?

Denis Noble

I also originally held that view. It was a debate with the Canadian philosopher Charles Taylor in 1967 that began the process by which I came to a very different view. In the first article, I demonstrated what Ernst Mayr and others argue, which is that for every high-level description there must exist a valid low-level description. Taylor replied that that may be true in any given case but that it would not explain what is happening if one takes a set of cases. They may be ordered only at the high level. I further replied that this move makes the issue one of explanation, i.e., conceptual rather than strictly empirical.

I now go much further. My work on heart rhythm taught me that the rhythm simply doesn’t exist at the molecular level. If I placed all the molecular components in a nutrient solution, but without being constrained by a living cell, the rhythm would not exist. By the usual ontological criteria the rhythm doesn’t exist at a molecular level but does exist at a cellular level.

So, if I'm reading him correctly, Noble seems to be saying that if you follow the reductionist route - in his example of the natural cardiac pacemaker - then, at the molecular level there is no trace of the pacemaker rhythm. But go up a level to the cellular level then the rhythm appears when the molecules become a system. I'm still not sure how this means that the goal (teleological purpose) arose from nowhere. He seems to be saying that the systematic arrangement of the molecules produces function and that function is, by definition, teleological. So, the question in my mind remains: what guides the arrangement of the molecules into a functioning system?
Just by the way, this article seems to confirm what has been pointed out earlier in this thread: that atheists continue to erect the strawman argument that religious (or spiritual) automatically means biblical creationism. The article, unfortunately, makes no distinction between evolution and Darwinism, not to mention neo-darwinism. Nor does it mention any challenges to current evolutionary orthodoxy other than creationism so, in effect, the article commits the same error that it reports.

Every time you asserted "no evidence" he (or Michael Larkin or David Bailey, etc.) came back with some and you reverted to your assertion. I don't think it will achieve anything to go down that dead-end street again - we may as well all re-read those threads on the Skeptiko forum.
Can you give a link to one of these pieces of evidence? David's argument was that a random search through sequence space wouldn't come up with anything in a reasonable time. I agreed and suggested that it's not a random search. I don't remember what Larkin said.

I'm curious about something though that no one's touched on to my recollection.  I'm pretty much intuitively convinced that if organisms were truly only evolving by RM + NS, that the random mutations would so often - almost always - be detrimental that the survival of any living thing would be close to impossible.  Has no IDer made and developed such an argument?

The feeling now is that many mutations are neutral, with most others detrimental and a few helpful. This is, in part, due to the degeneracy of the genetic code. Note that a detrimental mutation occurs in one or a few individuals and will often result in the death of those individuals.

How does the teleological agent operate?

I agree that people on both sides are often attacking a caricature of the other side. The only thing that this article says about what Christians might really believe is:

“To say that all things depend unilaterally on the eternal action of God is not the same as saying that specific steps in the universe’s history must be the direct result of divine intervention."

Not very enlightening.

This is about the UK and Canada. Of course they are more rational. Again, though, not much information.

"Furthermore, doubts about evolutionary science frequently appear to be related to the perceived limitations of evolutionary science-based explanations for human origins and human consciousness."

Many of the contributions by Lone Shaman were lost, either due to server crashes or deletion after he left the forum. However, some of the threads on the older Skeptiko forum still exist. I don't have time to pinpoint the dialogue I remember but the following is an example of what I was saying. This snippet is from yet another long thread...

Paul Wrote:Sorry, but you're the one making the claim. DNA is a functional code and we have absolutely no evidence that a mind was involved in its evolution. Unless you have evidence to the contrary, DNA is an example of an evolved functional code.

Reply from LS ...

Quote:I have presented evidence. It's not so much of a claim as inference. I'll say it again, the inference is as sound as any, and is falsifiable. I'm not required to prove anything. You don't really prove hypothesis, you only see how it fits against the evidence and it does. In fact it remains as the only valid explanation until science can show a naturally occurring code. Falsification is what your looking for. 

Paul Wrote:Why don't you write a short paragraph that summarizes your claim? Because, really, I have no idea why you think you've proved this. In particular, explain why you think your claim is falsifiable.

Lone Shaman Wrote:Paul, I've already explained my position on page one.

It is not about proof it is an inference. 

Once again an evolving code is not the issue. But your still pushing it for some reason. A simpler code is still a code. I would say the evolving potential must be towards error correction. That is what it appears to be. That would be sensible. I do believe in evolution you know.

Here's a paper that discusses many of the proposals for an evolving genetic code. There's a whole bunch here. Knock yourself out. 

The paper in our first link was one I would have linked myself! the second is in fact included in here.

He goes on to present more evidence.

Paul Wrote:I guess you're not willing to summarize it in a few sentences.

And it goes on like that. You can read it for yourself if you want more. David Bailey and Michael Larkin are both here and have both contributed to this thread. You might want to ask them to elaborate because they know their stuff much better than I do. I would recommend that anyone interested should take a look at that thread. Pity that later debates were lost but you get the gist of the arguments from this one.
