It is more difficult to deal with the self-esteem of man as man, because we cannot argue out the matter with some nonhuman mind. The only way I know of dealing with this general human conceit is to remind ourselves that man is a brief episode in the life of a small planet in a little corner of the universe, and that, for aught we know, other parts of the cosmos may contain beings as superior to ourselves as we are to jellyfish.
