[Looking for Diogenes]

Dembski has written extensively on how to falsify ID.

Yes, but all he says is that the only way to disprove ID is to prove evolution. In other words, the only way to disprove it is to prove a competing theory. Isn't there a way to disprove it without reference to Darwinism?

Is intelligent design falsifiable? Is Darwinism falsifiable? Yes to the first question, no to the second. Intelligent design is eminently falsifiable. Specified complexity in general and irreducible complexity in biology are within the theory of intelligent design the key markers of intelligent agency. If it could be shown that biological systems like the bacterial flagellum that are wonderfully complex, elegant, and integrated could have been formed by a gradual Darwinian process (which by definition is non-telic), then intelligent design would be falsified on the general grounds that one doesn't invoke intelligent causes when purely natural causes will do. In that case Occam's razor finishes off intelligent design quite nicely.

I would suggest that it must be shown that there exists a *purely natural* phenomena which is capable of information creation. This has never been shown. It is taken on faith, by the philosophical naturalists, that it *must* exist, because naturalism is assumed out of hand. Presumably, even though it cannot be shown, mutations and natural selection are capable of this. Dembski goes too far in his criterion for falsifiability in my opinion.
