Why did the author feel the necessity of ascribing a human origin to the Koran? I think it DID have a supernatural origin. Muhammed was talking to an unclean spirit in a cave and that's how the Koran was written.
Yes, it does, and also a little hyper. The author, Dr. Jack Wheeler, has a very interesting web autobiography that is certainly enlightening about him: Dr. Jack Wheeler.
Please understand, I don't like the ancient Aztec or Islamic "kultures" at all, but shoddy revisionist writing isn't the way to expose them.
