The God Delusion is a 2006 book by British evolutionary biologist, ethologist Richard Dawkins, a professorial fellow at New College, Oxford and, at the time of publication, 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, God, 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 statement in Lila (1991) that "when one person suffers from a delusion it is called insanity. When many people suffer from a delusion it is called religion." With many examples, he explains that one does not need religion to be moral and that the roots of religion and of morality can be explained in non-religious terms. In early December 2006, it reached number four in the New York Times Hardcover Non-Fiction Best Seller list after nine weeks on the list. More than three million copies were sold. According to Dawkins in a 2016 interview with Matt Dillahunty, an unauthorised Arabic translation of this book has been downloaded 3 million times in Saudi Arabia. The book has attracted widespread commentary, with many books written in response. Background Dawkins has argued against creationist explanations of life in his previous works on evolution. The theme of The Blind Watchmaker, published in 1986, is that evolution can explain the apparent design in nature. In The God Delusion he focuses directly on a wider range of arguments used for and against belief in the existence of a god (or gods). Dawkins identifies himself repeatedly as an atheist, while also pointing out that, in a sense, he is also agnostic, though "only to the extent that I am agnostic about fairies at the bottom of the garden". Dawkins had long wanted to write a book openly criticising religion, but his publisher had advised against it. By 2006, his publisher had warmed to the idea. Dawkins attributes this change of mind to "four years of Bush" (who "literally said that God had told him to invade Iraq"). By that time, a number of authors, including Sam Harris and Christopher Hitchens, who together with Dawkins were labelled "The Unholy Trinity" by Robert Weitzel, had already written books openly attacking religion.
