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. 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. In so doing, he makes a compelling case that belief in God is not just irrational, but potentially deadly. Dawkins has fashioned an impassioned, rigorous rebuttal to religion, to be embraced by anyone who sputters at the inconsistencies and cruelties that riddle the Bible, bristles at the inanity of "intelligent design," or agonizes over fundamentalism in the Middle East-or Middle America.

Richard Dawkins is the Charles Simonyi Professor for the Public Understanding of Science at Oxford University and a fellow of New College.

The Selfish Gene catapulted Richard Dawkins to fame and remains his most famous and widely read work. It was followed by a string of bestselling books: The Extended Phenotype, The Blind Watchmaker, River Out of Eden, Climbing Mount Improbable, Unweaving the Rainbow, The Ancestor's Tale and a collection of his shorter writings A Devil's Chaplain. Dawkins is a Fellow of both the Royal Society and the Royal Society of Literature. He is the recipient of numerous honours and awards, including the 1987 Royal Society of Literature Award, the 1990 Michael Faraday Award of the Royal Society, the 1997 International Cosmos Prize for Achievement in Human Science, the Kistler Prize in 2001 and the Shakespeare Prize in 2005.

The God Delusion was originally published in 2006 and has since become a worldwide bestseller.
