The Evolution of God

Extremely readable explanation and discussion of how monotheism developed in response to human social evolution and the surrounding facts on the ground, i.e. political and cultural circumstances. I've already bought another book of his (The Moral Animal) so I can enjoy even more of his writing style. He writes with a pithy, down-to-earth attitude, and I find myself chuckling at the way he boils down difficult concepts into a one-sentence reality that I repeat to myself long after I've shut the book.
