s the philosopher Philip Kitcher shows in his superb new book, Living With Darwin, the theory of intelligent design is a mixture of "dead science" and non-science. That is, insofar as ID makes scientific claims (for example, that natural selection cannot produce complexity), those claims not only are wrong, but were proved wrong years ago. And ID is deeply unscientific in its assertion that certain aspects of evolution (mutation, in Behe's case) required supernatural intervention. Behe's attacks on evolutionary theory are once again wrongheaded, but the intellectual situation grows far worse when we see what theory he offers in its place.
The first problem is that Behe's "scientific" ideas are offered to the public in a trade book, and have never gone through the usual process of vetting in peer-reviewed scientific journals. This was also the case with Darwin's Black Box. In fact, Behe has never published a paper supporting intelligent design in any scientific journal, despite his assertion in Darwin's Black Box that his own discovery of biochemical design "must be ranked as one of the greatest achievements in the history of science," rivaling "those of Newton and Einstein, Lavoisier and Schrödinger, Pasteur, and Darwin." Surely such an important theory deserves a place in the scientific literature! But the reason for the lack of peer review is obvious: Behe's ideas would never pass muster among scientists, despite the fact that anybody who really could disprove Darwinism would win great renown.

So let us put some empirical questions to Behe, since his theory is supposedly scientific. Which features of life were designed, as opposed to evolved? How exactly did the mutations responsible for design come about? Who was the Designer? To what end did the Designer work? If the goal was perfection, why are some features of life (such as our appendix or prostate gland) palpably imperfect?
