Putting the Cart Before the Horse

William Dembski quotes this astonishing passage from a speech given this spring by uber-Darwinist and atheist Daniel Dennett:

The late Steve Gould was really right when he called Richard and me Darwinian fundamentalists. And I want to say what a Darwinian fundamentalist is. A Darwinian fundamentalist is one who recognizes that either you shun Darwinian evolution altogether, or you turn the traditional universe upside down and you accept that mind, meaning, and purpose are not the cause but the fairly recent effects of the mechanistic mill of Darwinian algorithms. It is the unexceptioned view that mind, meaning, and purpose are not the original driving engines, but recent effects that marks, I think, the true Darwinian fundamentalist.

How can such heartless culling produce the magnificent designs that we see around us? It seems just about impossible that such a simple mechanical sieve could produce such amazing design in the biosphere.

Francis Crick called Orgel's Second Rule. "Evolution is cleverer than you are."

Again and again evolutionists, molecular biologists, biologists in general, see some aspect of nature which seems to them to be sort of pointless or daft or doesn't make much sense - and then they later discover it's in fact an exquisitely ingenious design - it is a brilliant piece of design - that's what Francis Crick means by Orgel's Second Rule.

This might almost look like a slogan for Intelligent Design theory. Certainly Crick was not suggesting that the process of evolution was a process of intelligent design. But then how can evolution be cleverer than you are?

What you have to understand is that the process itself has no foresight; it's entirely mechanical; has no purpose - but it just happens that that very process dredges up, discovers, again and again and again, the most wonderfully brilliant designs - and these designs have a rationale. We can make sense of them. We can reverse-engineer them, and understand why they are the wonderful designs they are.

It would help us to understand how this is possible if we could break all this brilliant design work up into processes which we could understand the rationale of, without attributing it to the reason of some intelligent designer. [In other words, it would help if there were a shred of evidence for Darwinian algorithms having the creative power that Dennett attributes to them. -WmAD]

These processes are arms races. Not just arms races between armies of intelligent people, but arms races between trees, and between bacteria, and between any form of life you want to name. We can watch an arms race generate more and more design, more exquisite solutions to problems, in ways that are strikingly similar to the more intelligently (but not very intelligently) guided arms races that give us the metaphor in the first place.

Of all the species on the planet, Homo sapiens, is exceptional: it is the only species that has evolved that can understand that it's one of the fruits on the tree of life.

It's hard to read this without getting the feeling that Dennett is trying with all his might not to admit that living things certainly appear to be intelligently designed. Indeed, were it not for Dennett's a priori committment to atheism he would probably not even bother to engage in such a laborious struggle. He gives the game away in this paragraph where he tries to convince us that a blind, mecahnical process is even more brilliant, more ingenious, than the most clever of human engineers:

What you have to understand is that the process itself has no foresight; it's entirely mechanical; has no purpose - but it just happens that that very process dredges up, discovers, again and again and again, the most wonderfully brilliant designs - and these designs have a rationale. We can make sense of them. We can reverse-engineer them, and understand why they are the wonderful designs they are.

Dennett's confidence that, despite all appearances to the contrary, living things are not really intelligently designed rests upon his confidence that there is no intelligent designer. In philosophy this sort of thinking is called begging the question, or less technically, putting the cart before the horse.
