With rigor and wit, Dawkins examines 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. He eviscerates the major arguments for religion, and demonstrates the supreme improbability of a supreme being. He shows how religion fuels war, foments bigotry, and abuses children, buttressing his points with historical and contemporary evidence.
