"I have assumed that the layman has no special knowledge, but I have not assumed that he is stupid" says Richard Dawkins, the talented popularizer of Biology, in his Selfish Gene. Yet, he seems to change his opinion regarding the layman in The God Delusion, as the book is filled with all kinds of fallacious arguments. Dawkins' preference to attack arguers rather than the arguments and his misrepresentation of the opponents' views are some, but not all, of the fallacies committed throughout the book. The logical fallacies in the book show how ideology can lead to faulty logical reasoning and turn a world famous scientist into an ordinary propagandist. This article aims both to reveal some of the book's logical fallacies that constitute perfect examples of weak reasoning and also to contribute to the possibilities of a better, more productive debate.
