Discover magazine recently called Richard Dawkins "Darwin\'s Rottweiler" for his fierce and effective defense of evolution. Prospect magazine voted him among the top three public intellectuals in the world (along with Umberto Eco and Noam Chomsky). Now Dawkins turns his considerable intellect on religion, denouncing its faulty logic and the suffering it causes. He critiques God in all his forms, from the sex-obsessed tyrant of the Old Testament to the more benign (but still illogical) Celestial Watchmaker favored by some Enlightenment thinkers.
