"Whatever you call it, there is a struggle in the universe between good and evil. Now not only is that struggle structured out somewhere in the external forces of the universe, it's structured in our own lives. Psychologists have tried to grapple with it in their way, and so they say various things. Sigmund Freud used to say that this tension is a tension between what he called the id and the superego. Some of us feel that it's a tension between God and man."
