Richard Dawkins, in The God Delusion, tells of his exasperation with colleagues who try to play both sides of the street: looking to science for justification of their religious convictions while evading the most difficult implications—the existence of a prime mover sophisticated enough to create and run the universe, "to say nothing of mind reading millions of humans simultaneously." Such an entity, he argues, would have to be extremely complex, raising the question of how it came into existence, how it communicates —through spiritons!—and where it resides. Dawkins is frequently dismissed as a bully, but he is only putting theological doctrines to the same kind of scrutiny that any scientific theory must withstand. No one who has witnessed the merciless dissection of a new paper in physics would describe the atmosphere as overly polite.
Dawkins has argued against all 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 God (or gods).
