Richard Dawkins is delusional. That might be a strange thing to say about an evolutionary biologist at Oxford University, but his new book, "The God Delusion" (406 pages of turgid polemics published in late 2006 by Houghton Mifflin), amply documents his delusion. And what is that delusion? That Dawkins is debunking religion -- all religion, for all time and eternity. The bigger delusion, really, is that Dawkins thinks he's talking about religion at all.
