I started out to read Darwin with the purpose of finding out what was what. The more I found out about controversies surrounding books, the more likely I was to read them. Of course Darwin and the rest of them assumed that people knew everything about the facts of life, so they didn't mention that. However, the most vivid religious experience I ever had was when I finished Darwin's Descent of Man. I can't think of anything that influenced me more deeply than that. I got out of bed and thanked God for evolution. It confirmed everything that was beautiful.
