[W]hen you have eliminated the impossible whatever remains, however improbable, must be the truth...
The Sign of the Four, Sir Arthur Conan Doyle
It doesn't matter that they're calling it "Intelligent Design" now. Creationism is the same thing it was in the beginning, is now, and ever shall be: a hollow hypothesis striving frantically to stave off its own extinction. Although creationism responds to environmental pressures by adapting in hopes of survival -- adding "science" in its guise as "creation science" or "scientific creationism", or even dropping "creation" entirely along with the identity of the creator in "intelligent design" -- the evolution of creationism cannot disguise that it is a wholly negative enterprise.
The idea is simple enough. First, establish creationism (in whatever form) as the only alternative to evolution. Second, destroy evolution. Third, proclaim the sole survivor as victor. Unfortunately for the creationists, proving a negative is as difficult as they have always said it is (as when they criticize those who believe God does not exist). William Dembski has his explanatory filter, which purports to detect the presence of purposeful design. The only problem with Dembski's EF is that it doesn't work, since he can't give any examples of its use (although it does seem to suggest that God was intelligently designed). Not to worry, Dembski's still working on it. At least he's a trained mathematician, which means he can throw in fancy symbols whenever he needs to distract the unwary.
Michael Behe has his irreducible complexity, which means that some biological mechanisms cannot be functional if even a single component is missing. This is difficult to prove, as you might imagine, but assume Behe is correct for a second. What he misses, however, is that while the reduced mechanism might no longer be able to perform the task it was executing, it might be perfectly capable of performing some other useful task. Behe has failed to come to grips with natural selection's unapologetic opportunism, taking whatever is close at hand and shaping it in response to environmental influences. Remember that this was a gambit, by the way. We assumed Behe had demonstrated an irreducibly complex biological mechanism, but he really hasn't. His showcase arguments about bacterial flagella and the blood-clotting sequence have been picked apart by biologists with more imagination that he has.
While nature supposedly abhors a vacuum, creationism is desperate to create one that will suck it into the mainstream. Since creationism has no explanatory power ("God did it" is not an explanation), its proponents must carry the battle to the enemy in a war against science and the scientific method. While scientific controversies are settled in a contest of facts and observations, the "controversy" over evolution versus creation is a political dispute between creationist propaganda and scientific research. In the long term, science has a good record of ousting superstition. I just wish I were more confident about the near term.
