Behe’s Take: Miller vs. Luskin

The back-and-forth between Casey Luskin and Kenneth Miller has been going on for a couple weeks now, both on this blog and over at Carl Zimmer’s blog, and now Michael Behe weighs in on the debate over what he meant when he wrote about the blood clotting cascade in Darwin’s Black Box:

In Chapter 4 of Darwin’s Black Box I first described the clotting cascade and then, in a section called “Similarities and Differences”, analyzed it in terms of irreducible complexity. Near the beginning of that part I had written, “Leaving aside the system before the fork in the pathway, where details are less well known, the blood clotting system fits the definition of irreducible complexity… The components of the system (beyond the fork in the pathway) are fibrinogen, prothrombin, Stuart factor, and proaccelerin.” Casey Luskin concludes that from that point on I was focusing my argument on the system beyond the fork in the pathway, containing those components I named. That is a reasonable conclusion because, well, because that’s what I said I was doing, and Mr. Luskin can comprehend the English language.
Apparently Prof. Miller can’t. He breathlessly reports that one page after I had qualified my argument I wrote “Since each step necessarily requires several parts, not only is the entire blood-clotting system irreducibly complex, but so is each step in the pathway” and Miller asserts that meant I had inexplicably switched back to considering the whole cascade, including the initial steps. It seems not to have occurred to Miller that that sentence should be read in the context of the previous page, so he focuses on the components before the fork, the better to construct a strawman to knock down.
