I've often thought of that, and I suppose closely related to that question is the question of—what were the people who were persecuting afraid of? What were the Nazis afraid of? As a psychologist, I suppose I should have some clue to the answer to those disturbing questions, but I must confess, I do not have the answer. It would seem to me that type of cruel—there, and sometimes cruel to the point of destruction of human beings, is evident of deep-seated ignorance and superstition among human beings, which they can rationalize by such things as, you know, pointing out the inferiority of the people whom they are destroying, actually or psychologically. They can give you all sorts of good reasons, but when you examine those reasons what you really see is ignorance and superstition which is rather pervasive, unfortunately, very common among human beings. Ad they, they destroy each other, or go out of their way to hurt their fellow human beings. And the question there, there must be something deep down that they fear—that it doesn't—whatever it is, it doesn't seem to me to be rational, and obviously not moral, or human.
