The God Delusion is a 2006 bestselling non-fiction book by British biologist Richard Dawkins, professorial fellow of New College, Oxford, and inaugural holder of the Charles Simonyi Chair for the Public Understanding of Science at the University of Oxford. In The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that belief in a personal god qualifies as a delusion, which he defines as a persistent false belief held in the face of strong contradictory evidence. He is sympathetic to Robert Pirsig''s observation in Lila that "when one person suffers from a delusion it is called insanity. When many people suffer from a delusion it is called religion."
