Par For The Course

Saw this at First Things: Pandering to Prejudices


You usually know that somebody is losing the argument when he loses his cool and resorts to bluster, abuse, caricature, and the invocation of authorities who agree with him. The New York Times Book Review, for reasons that surpass charitable explanation, gave Michael Behe’s most recent book, The Edge of Evolution: The Search for the Limits of Darwinism, to Richard Dawkins for review. Behe is a biochemist, author of Darwin’s Black Box, and a proponent of Intelligent Design. Dawkins is an atheist polemicist against religion, holds the ill-named Chair for the Public Understanding of Science at Oxford, and is author of The God Delusion.

Dawkins begins by saying he feels “sorry” for Behe, whom he describes as the “poster boy of creationists everywhere.” Never mind that Behe is not a “creationist.” No less than three times in the review, Dawkins alludes to the fact that Behe’s colleagues in his university’s biology department have publicly distanced themselves from his position. The other biologists at Lehigh University disagree with Behe. It follows that he must be a nut. Further, “Behe is taking on Ronald Fisher, Sewall Wright, J.B.S. Haldane, Theodosius Dobzhansky, Richard Lewontin, John Maynard Smith, and hundreds of their talented coworkers and intellectual descendents.” This is what is known as argument from authority.

This sort of intellectual dishonesty seems to be contagious. I picked up a copy of Skeptic magazine recently and I was horrified at the liberal use of shoddy rhetorical devices and ad hominem attacks which they were passing off as rational discourse. Maybe it is the effect generated from the (very enjoyable) Penn & Teller Bullshit television program, where humor and not-so-good natured put downs are the order of the day. But, the purpose of a television program is to be entertaining at least and maybe thought provoking at best. A magazine like Skeptic should aim considerably higher since the pages of a journal offer the opportunity for something a tv show could never deliver, namely the above mentioned rational discourse.

First Things continues:


All this raises interesting questions about the Book Review, which publicly claims to take care that a reviewer has no conflict of interest that would get in the way of a fair treatment of a book. For instance, is the author your brother-in-law? Apparently it doesn’t matter if a prospective reviewer has publicly and repeatedly heaped contempt on an author and his arguments.

First Things has a different review policy. We will on occasion choose a reviewer who is known to disagree, and disagree strongly, with an author. The purpose is to engage the argument and explain why it is wrong, with the author having a chance to respond. As the editors of the Book Review must know, Dawkins cannot engage Behe’s argument. It is not simply that he is not a biochemist. He is in principle disqualified because he is a militant atheist committed to a position of scientific materialism in which any reference to transcendent purpose or design is deemed to be delusional, meaning it is the product of a mental disorder.

It is hard to know what purpose is served by the Book Review in having Dawkins review Behe, except, possibly, to ostracize anyone who presumes to raise questions about prevailing Darwinist orthodoxies and, perhaps, to pander to the smug prejudices of the presumed readership of the Times.

Indeed, any polemicist like Dawkins would be a poor choice as book reviewer. It is in the nature of such people to just re-issue their own polemics rather than actually engage with material they disagree with. A review written by Dawkings is going to be about Dawkins and nothing else. The choice of the Book Review seems to indicate that they would prefer their readers to only read and know what Dawkins wants them to read and know. It sort of reminds one of those late medieval scholastics who made their pupils swear to never contradict Aristotle. "Stop thinking. We will tell you what is acceptable to think about."

More from First Things:


Just who does this Behe guy, “the disowned biochemist of Lehigh University,” think he is to disagree with the scientific establishment? Doesn’t he know that science progresses by conformity to conventional opinion, as Nicolaus Copernicus, Isaac Newton, and Charles Darwin (!) have taught us? Dawkins’ clinching argument against Behe’s claims about the limits of natural mutation is that different kinds of dogs have descended from the wolf. Dawkins writes, “As I incredulously close this book, I seem to hear mocking barks and deep baying howls of derision from 500 breeds of dogs.”

When you read things like this you really have to wonder if Dawkins is paying attention to what he is writing. After all, why are there 500 breeds of dogs? Largely because an outside force (i.e. man) has been directing their evolutionary path. This is an argument for "natural" mutation how exactly?

My own take of Behe, based on his earlier book Darwin's Black Box, is that he does a good job in taking apart some of the easy complacency built into the prevailing orthodoxy. There are very hard questions out there to which we do not have satisfactory answers. Behe contends the assumption that the answers to those questions will fall in line with the Darwinian orthodoxy is unfounded. On this Behe is correct, both from the view of formal logic and that of the scientific process. If Behe's negative critique is well founded, his positive postulation of Intelligent Design as the "answer" to all of these problems is far less persuasive, as it is more of a throwing up of hands instead of an actual answer. My own guess (and a guess it all it is) would be that something will come along which will modify the present Darwinian synthesis profoundly, possibly along scientific ideas that mirror the self-organizing philosophic premise of elan vital put forward by the French philosopher Henri Bergson.

That is why it is so damaging to the idea of science to have someone like Richard Dawkins out front and center. Dawkins is less interested in science than he is interested in attacking religion. For Dawkins, science is not the fruit of a free and open inquiry into the nature of the universe but a bludgeon he can use to bash those he calls delusional. Any use of science for ideological ends winds up perverting science. Dawkinism is in effect a new Lysenkoism.

FYI-Michael Behe wrote the blurb on Dawkins in TIME's Most Influential People Issue this year:

Richard Dawkins
By Michael Behe
Of Richard Dawkins' nine books, none caused as much controversy or sold as well as last year's The God Delusion. The central idea—popular among readers and deeply unsettling among proponents of intelligent design like myself—is that religion is a so-called virus of the mind, a simple artifact of cultural evolution, no more or less meaningful than eye color or height.

It is a measure of the artful way Dawkins, 66, an evolutionary biologist at the University of Oxford, tells a tale and the rigor he brings to his thinking that even those of us who profoundly disagree with what he has to say can tip our hats to the way he has invigorated the larger debate.

Dawkins had a mild Anglican youth but at 16 discovered Charles Darwin and believed he'd found a pearl of great price. I believe his new book follows much less from his data than from his premises, and yet I admire his determination. Concerning the big questions, the Bible advises us to be hot or cold but not lukewarm. Whatever the merit of his ideas, Richard Dawkins is not lukewarm.

Behe is the author of the upcoming The Edge of Evolution

"When you read things like this you really have to wonder if Dawkins is paying attention to what he is writing. After all, why are there 500 breeds of dogs? Largely because an outside force (i.e. man) has been directing their evolutionary path. This is an argument for "natural" mutation how exactly?"

I don't know if you read Dawkins' review itself, but he doesn't suggest that the existence of 500 breeds of dogs was due to "natural mutation"- he makes the argument, correct or not, that the same limitations that Behe would apply to natural mutations should apply to forced mutations (I don't know enough about the issue to comment on its merits- but the person you're quoting at First Things seems to bastardize Dawkins' argument). Here's the passage in it's complete form:

"But let’s follow Behe down his solitary garden path and see where his overrating of random mutation leads him. He thinks there are not enough mutations to allow the full range of evolution we observe. There is an “edge,” beyond which God must step in to help. Selection of random mutation may explain the malarial parasite’s resistance to chloroquine, but only because such micro-organisms have huge populations and short life cycles. A fortiori, for Behe, evolution of large, complex creatures with smaller populations and longer generations will fail, starved of mutational raw materials.

If mutation, rather than selection, really limited evolutionary change, this should be true for artificial no less than natural selection. Domestic breeding relies upon exactly the same pool of mutational variation as natural selection. Now, if you sought an experimental test of Behe’s theory, what would you do? You’d take a wild species, say a wolf that hunts caribou by long pursuit, and apply selection experimentally to see if you could breed, say, a dogged little wolf that chivies rabbits underground: let’s call it a Jack Russell terrier. Or how about an adorable, fluffy pet wolf called, for the sake of argument, a Pekingese? Or a heavyset, thick-coated wolf, strong enough to carry a cask of brandy, that thrives in Alpine passes and might be named after one of them, the St. Bernard? Behe has to predict that you’d wait till hell freezes over, but the necessary mutations would not be forthcoming. Your wolves would stubbornly remain unchanged. Dogs are a mathematical impossibility.

Don’t evade the point by protesting that dog breeding is a form of intelligent design. It is (kind of), but Behe, having lost the argument over irreducible complexity, is now in his desperation making a completely different claim: that mutations are too rare to permit significant evolutionary change anyway. From Newfies to Yorkies, from Weimaraners to water spaniels, from Dalmatians to dachshunds, as I incredulously close this book I seem to hear mocking barks and deep, baying howls of derision from 500 breeds of dogs — every one descended from a timber wolf within a time frame so short as to seem, by geological standards, instantaneous."

P.S. I generally agree with you that having people diametrically opposed to each other write book reviews, especially in a supposedly neutral outlet such as the NY Times Book Review (yes, I hear the howls of laughter from both sides of the blogosphere) is not a good idea. It comes across as "tabloidish" for lack of a better term.

It is a very weird argument, because I've never heard anyone claim it is either "mutation, rather than selection", and while I haven't read Behe's new book I have to believe it is Dawkin's offering the bastardization of the original argument. It seems Behe made an additional claim that the geological age of the earth hasn't allowed for enough time to pass for the combination of mutation AND natural selection to account for the variety of life on Earth. It is a nonsense argument to posit anything else (and if Behe's argument was that natural selection plays no role I'm sure Dawkins would come right out and say so, since it would be obvious bullshit). Therefore, Dawkins argument via dogs (with obvious interference of man) simply wouldn't address the point. As usual Dawkins seems to be being deliberately obtuse, such as his claim that "irreducible complexity" is simply a question of Behe's ignorace (or the ignorance of science as a whole) which isn't what the concept is about at all. IN this case Behe's claim that mutation AND random selection work too slowly is presented as being MUTATION alone is too slow. Obviously Behe's ACTUAL argument is that mutation AND intelligent direction is quicker (as the case of dogs would seem to bear out, as wild wolves are relatively unchanged over the last 10,000 years.)

I have no idea if Behe's argument is correct, and on the whole I tend to doubt it...at least as far as ID proper goes. It may or may not indicate an actual "hole" in the Darwinian synthesis. I'm sure I can't tell much of anything from Dawkins exposition of it.

Just a follow-up: earlier in the review Dawkins suggests that Behe believes that natural selection is a trivial matter (I pasted the passage below). How accurate a reading of Behe's book that is, I have no idea.

"Behe correctly dissects the Darwinian theory into three parts: descent with modification, natural selection and mutation. Descent with modification gives him no problems, nor does natural selection. They are “trivial” and “modest” notions, respectively. Do his creationist fans know that Behe accepts as “trivial” the fact that we are African apes, cousins of monkeys, descended from fish?

The crucial passage in “The Edge of Evolution” is this: “By far the most critical aspect of Darwin’s multifaceted theory is the role of random mutation. Almost all of what is novel and important in Darwinian thought is concentrated in this third concept.”"

For what it's worth, here's the link to the entire review:
http://www.nytimes.com/2007/07/01/books/review/Dawkins-t.html?pagewanted=1&ei=5070&en=ea6e7eb5a408fb91&ex=1186545600

Most importantly, it was my understanding there would be no evolutionary biology in the program tonight.

That confirms for me that Dawkins is (yet again) playing fast & loose with what Behe is actually saying. Random mutation has ALWAYS been viewed as the vehicle that accounted for the most dramatic change and for keeping the steady supply of genetic variation required in the evolutionary process. (Didn't Dawkins ever read The Selfish Gene?) To claim surprise that Behe finds mutation an important factor is risible.

Notice Dawkings snide little ad hominem?

"Do his creationist fans know that Behe accepts as “trivial” the fact that we are African apes, cousins of monkeys, descended from fish?"

That's right. Let's judge Behe's work not by its content but by the religious beliefs of others.

Wouldn't it have been more honest to point out that Behe doesn't seem to be a creationist?
