I think about my education sometimes. I went to the University of Chicago for awhile after the Second World War. I was a student in the Department of Anthropology. At that time they were teaching that there was absolutely no difference between anybody. They may be teaching that still. Another thing they taught was that no one was ridiculous or bad or disgusting. Shortly before my father died, he said to me, 'You know - you never wrote a story with a villain in it.' I told him that was one of the things I learned in college after the war.
