These are not your daddy's creationists. When scientists and other members of the reality-based community declare that evolution is the only valid and provable account of our planet's natural history, intelligent design boosters don't cite the Bible. Instead, they earnestly insist that no one ought to claim a monopoly on truth, and that in the interests of intellectual and moral pluralism, "alternatives" to evolution should get a fair hearing in schools.

The new relativism marks quite a shift from the arguments normally employed by the right. Remember the "culture wars" of the late '80s and early '90s, when conservatives in the administrations of Ronald Reagan and George H.W. Bush, such as William Bennett and Lynne Cheney, inveighed against the "relativism" that allegedly dominated the thinking of American intellectuals?

So it's a tad ironic that conservatives and the religious right are now arguing that intelligent design should be taught on the grounds of intellectual pluralism. Needless to say, from the perspective of virtually all reputable scientists, evolution isn't just one theory among many, it's the only scientifically proven account of the origin and development of life on Earth. Denying evolution isn't merely "another perspective." It's like insisting that the sun revolves around the Earth, or that the moon is inhabited by little green guys. Whatever happened to truth?
