In his most recent book, British scientist Richard Dawkins writes about the irrationality of a belief in God, examines God in all his forms and sets down his arguments for atheism. The book is The God Delusion.
Dawkins is a professor of "the public understanding of science" at Oxford University.
The New York Times Book Review has hailed him as a writer who "understands the issues so clearly that he forces his reader to understand them too."
