In this provocative New York Times bestseller, now published in paperback with a new preface, the preeminent scientist; and the world’s most prominent atheist; Richard Dawkins eviscerates the major arguments for religion and demonstrates the supreme improbability of a supreme being. The God Delusion makes a compelling case that belief in God is not just wrong, but potentially deadly. With rigor and wit, Dawkins asserts the irrationality of belief in God and the grievous harm religion has inflicted on society, from the Crusades to 9/11. Supporting his points with historical and contemporary evidence, he shows how religion fuels war, foments bigotry, and abuses children. The God Delusion also offers exhilarating insight on the advantages of atheism to the individual and society, not the least of which is a clearer, truer appreciation of the universes wonders than any faith could ever muster. This is a book that challenges each of us to test our beliefs, no matter what beliefs we hold.
