“Is intelligent design falsifiable? Is Darwinism falsifiable? Yes to the first question, no to the second question.” You might think that it’s Michael Behe again; after all, he’s on the record as having asserted, “ID is quite susceptible to falsification” while “Darwinism seems quite impervious to falsification.” (He said so in his “The Modern Intelligent Design Hypothesis” ; I argued that he was mistaken in “Falsifia-behe-lity,” and noted in “Falsifia-behe-lity on the Edge” that he seems to have quietly abandoned the claim by the time of his second book, The Edge of Evolution .) But no. Instead, it’s William A. Dembski, the chief theoretical architect of the “intelligent design” movement, in his No Free Lunch (2002). You might think that, since Dembski, unlike Behe, is trained in philosophy, that his argument will be clearer, crisper, and perhaps even not obviously misguided. But, again, no.
