The idea of the supernatural as being something over and above the natural is a killing idea. In the Middle Ages this was the idea that finally turned that world into something like a wasteland, a land where people were living inauthentic lives, never doing a thing they truly wanted to because the supernatural laws required them to live as directed by their clergy. In a wasteland, people are fulfilling purposes that are not properly theirs but have been put upon them as inescapable laws. This is a killer.
