William Dembski Debates Lewis Wolpert

William Dembski reports,

Lewis Wolpert and I had an audio debate a few weeks ago, which is now available online as a podcast: go here (there’s about three minutes of stage-setting by the interviewer Justin Brierly before the actual discussion with Wolpert begins). The debate is part of a program series called UNBELIEVABLE. Other debates available there include one between Denis Alexander and PZ Myers and also one between Richard Dawkins and John Lennox.

Wintery Knight provides a good summary of the debate here.

In Defense of Thomas Nagel

A few days ago I mentioned the recent attacks against philosopher Thomas Nagel by philosopher Brian Leiter of Leiter Reports due to Nagel’s choice of Stephen Meyer’s book Signature in the Cell as one of the best books of 2009.  In a review of one of Nagel’s recent books, philosopher and historian David Gordon defends Nagel’s right to recognize Meyer and comments on Leiter’s gratuitous attacks.

Nagel’s remarks on Intelligent Design are of great philosophical significance. He is an atheist and does not accept the view that a designing mind directed the evolutionary process. But he opposes what he deems a contemporary prejudice in favor of reductionist naturalism. He doubts that Darwinism can adequately explain the existence of objective value and looks instead to an immanent teleology in the world.

Although he does not accept Intelligent Design, Nagel refuses to dismiss the movement as merely religious. Critics claim that design cannot be a legitimate scientific hypothesis; but at the same time, they maintain that the theory can be shown to be false. Nagel pertinently asks, how can both of these assertions be true together? Further, Nagel sees no constitutional obstacle to teaching Intelligent Design.

Nagel’s opinions on this issue have led to a remarkable episode. Brian Leiter runs a blog, Leiter Reports, which is read by philosophers, owing to detailed accounts of promotions, jobs, and other news about philosophy departments. Leiter’s comparative rankings of philosophy departments also attract much attention. Leiter obtrudes his own political and social views on his audience; were he to present these in a separate venue, it is a safe bet that his audience would vastly diminish. Among Leiter’s many aversions, the Intelligent Design movement ranks among the foremost: he often attacks what he calls the “Texas Taliban.”

When Nagel’s article on Intelligent Design appeared, Leiter could not contain his rage (see here and here). We were presented with the unedifying spectacle of Leiter’s speaking in abusive and condescending terms about one of the foremost philosophers of the past half-century. Nagel’s The Possibility of Altruism, The View From Nowhere, and the essays collected in Mortal Questions are classics of contemporary philosophy.

Matters worsened when Nagel recommended in The Times Literary Supplement Stephen Meyer’s Signature in the Cell as one of his “Best Books of the Year.” Meyer is a leading proponent of Intelligent Design, and his book argues that naturalistic accounts of the origin of life on earth confront severe difficulties. Only a designing intelligence, Meyer contends, can account for the intricately specified information contained in DNA. Nagel did not endorse Meyer’s conclusion but praised the book for its account of the “fiendishly difficult” problem of life’s origin.

This recommendation aroused Leiter to new heights of contumely. It seems quite likely that Leiter never bothered to look at Meyer’s book. He quoted from an English professor of chemistry protesting Nagel’s claim that natural selection cannot account for DNA because it presupposes its existence. The chemistry professor, echoed by Leiter, said that natural selection exists in the preorganic world: was not Nagel ignorant to deny this? Both Leiter and the chemist ignored the fact, much emphasized by Meyer, that such resorts to natural selection are controversial. To appeal to the fact of their existence against Nagel is to assume what is much in dispute. Leiter extended his attack to accuse Nagel of ignorance of the relevant fields of study. Nagel has never claimed authority in biology; but had Leiter bothered to read Nagel’s well-known essay, “Brain Bisection and the Unity of Consciousness,” he would discover that Nagel has more than a passing acquaintance with neurobiology.

I have gone on at some length about this, because the attempt by Leiter and others to block inquiry that challenges naturalism seems to me altogether deplorable. To some people, evidently, the first line of the False Priestess in In Memoriam is Holy Writ, not to be questioned: “The stars, she whispers, blindly run.” But even if these avid naturalists are correct in their metaphysics, debate needs to be encouraged rather than suppressed. Perhaps Leiter should reread On Liberty. Pending that happy event, one can only say of his abuse that the barking of Bill Sikes’s dog just tells us that Bill Sikes is in the neighborhood.

Brian Leiter’s Ongoing Attacks Against Thomas Nagel

By any accounts, Thomas Nagel has proven himself a more nimble philosopher than the hamfisted Brian Leiter. That’s perhaps why Leiter simply can’t get over that Nagel liked Stephen Meyer’s SIGNATURE IN THE CELL (reported at UD here). For Leiter, when scholars of Nagel’s stature endorse books coming out of the rogue Discovery Institute, that endorsement itself constitutes an attack on liberal democracy, cultured discourse, science, etc. Leiter simply can’t let this go. Here are the posts to date on his blog:

Here is a short response from Nagel to a chemist named Stephen Fletcher who criticized Nagel for recommending Signature in the Cell.

Sir, – Stephen Fletcher objects to my recommending Stephen C. Meyer’s Signature in the Cell in Books of the Year. Fletcher’s statement that “It is hard to imagine a worse book” suggests that he has read it. If he has, he knows that it includes a chapter on “The RNA World” which describes that hypothesis for the origin of DNA at least as fully as the Wikipedia article that Fletcher recommends. Meyer discusses this and other proposals about the chemical precursors of DNA, and argues that they all pose similar problems about how the process could have got started.

The tone of Fletcher’s letter exemplifies the widespread intolerance of any challenge to the dogma that everything in the world must be ultimately explainable by chemistry and physics. There are reasons to doubt this that have nothing to do with theism, beginning with the apparent physical irreducibility of consciousness. Doubts about reductive explanations of the origin of life also do not depend on theism. Since I am not tempted to believe in God, I do not draw Meyer’s conclusions, but the problems he poses lend support to the view that physics is not the theory of everything, and that more attention should be given to the possibility of an expanded conception of the natural order.

Jerry Coyne on the Craig-Ayala Debate on Intelligent Design

I haven’t been able to find the original source of this quote, but it was cited by someone asking a question on William Lane Craig’s website.  The following is the question, quote, and Dr. Craig’s reply.

*UpdateIt turns out that this quotation actually came from a review Coyne posted of Ann Coulter’s book Godless.  Apparently, someone (the questioner or his/her source) replaced Coulter’s name with Craig’s in the quote.  Coyne brought this to Craig’s attention, and Craig removed the original post.  See their exchange here.


Question 1:

Jerry Coyne replies to your recent debate:

“What is especially striking is Craig’s failure to tell us what he really believes about how the earth’s species got here. It’s clear that he thinks God had a direct hand in it, but beyond that we remain unenlightened. IDers believe in limited amounts of evolution. Does Craig think that mammals evolved from reptiles? If not, what are those curious mammal-like reptiles that appear exactly at the right time in the fossil record? Did humans evolve from ape-like primates, or did the Designer conjure us into existence all at once? How did all those annoying fossils get there, in remarkable evolutionary order?

“And, when faced with the real evidence that shows how strongly evolution trumps ID, he clams up completely. What about the massive fossil evidence for human evolution — what exactly were those creatures 2 million years ago that had human-like skeletons but ape-like brains? Did a race of Limbaughs walk the earth? And why did God — sorry, the Intelligent Designer — give whales a vestigial pelvis, and the flightless kiwi bird tiny, nonfunctional wings? Why do we carry around in our DNA useless genes that are functional in similar species? Did the Designer decide to make the world look as though life had evolved? What a joker! And the Designer doesn’t seem all that intelligent, either. He must have been asleep at the wheel when he designed our appendix, back, and prostate gland.

“What’s annoying about Craig is that he demands evidence for evolution (none of which he’ll ever accept), but requires not a shred of evidence for his alternative hypothesis.

“Scientists gain fame and high reputation not for propping up their personal prejudices, but for finding out facts about nature. And if evolution really were wrong, the renegade scientist who disproved it — and showed that generations of his predecessors were misled — would reach the top of the scientific ladder in one leap, gaining fame and riches. All it would take to trash Darwinism is a simple demonstration that humans and dinosaurs lived at the same time, or that our closest genetic relative is the rabbit. There is no cabal, no back-room conspiracy. Instead, the empirical evidence for evolution just keeps piling up, year after year.”

Care to respond?

Tom

Dr. Craig responds:

I wasn’t aware that Coyne, a prominent biologist at the University of Chicago, had taken any cognizance of my debate with Francisco Ayala on “Is Intelligent Design Viable?” His response is precious because it illustrates so clearly exactly what I said in the debate: Darwinists tend to confuse the evidence for the thesis of common ancestry with evidence for the efficacy of the mechanisms of random mutation and natural selection. Did you notice, Tom, how all of Coyne’s remarks pertain to the former, not the latter? And yet it was precisely evidence for the latter that I was asking for in the debate. It just amazes me how such brilliant men can be so inattentive to the structure of an argument. As for his other questions, I addressed them specifically in the debate and the public Q & A that followed.

Thomas Nagel Selects Signature in the Cell as One of Top Books of 2009

Atheist philosopher Thomas Nagel praised Signature in the Cell in the Times Literary Supplement, stating,

Stephen C. Meyer’s Signature in the Cell: DNA and the evidence for Intelligent Design (HarperCollins) is a detailed account of the problem of how life came into existence from lifeless matter – something that had to happen before the process of biological evolution could begin. The controversy over Intelligent Design has so far focused mainly on whether the evolution of life since its beginnings can be explained entirely by natural selection and other non-purposive causes. Meyer takes up the prior question of how the immensely complex and exquisitely functional chemical structure of DNA, which cannot be explained by natural selection because it makes natural selection possible, could have originated without an intentional cause. He examines the history and present state of research on non-purposive chemical explanations of the origin of life, and argues that the available evidence offers no prospect of a credible naturalistic alternative to the hypothesis of an intentional cause. Meyer is a Christian, but atheists, and theists who believe God never intervenes in the natural world, will be instructed by his careful presentation of this fiendishly difficult problem.

Stephen Meyer vs. Michael Shermer

The Debate Over Darwin Continues: Stephen Meyer vs. Michael Shermer in Beverly Hills

In less than two weeks we will witness the rematch of the decade as Stephen Meyer and Michael Shermer face off on the question of intelligent design versus evolution.

Meyer vs. ShermerThese two men have met several times before, most recently at Freedomfest in Las Vegas in 2008 (click here for video). They also sparred in 2005 at Westminster College and appeared together on Lee Strobel’s Faith Under Fire program (video here). It will be interesting to see the new insights into the questions at hand as this debate has matured and developed.

The debate is hosted by the American Freedom Alliance and will take place at the prestigious Saban Theater in Beverly Hills on Monday, November 30, at 7:30pm. Dr. Meyer and Dr. Shermer will be joined by Dr. Richard Sternberg and Dr. Donald Prothero, respectively.
