"Superman represents an instinctive problem that we are all born and grown up with, that we can fly ─ after all, we can fly now; we couldn't before ─ and that we can carry on all kinds of scientific investigations, that we can stop crime, which Superman does, and that we can have a good influence on the world, and that we can be protected by the powerful influences in the world which may be our own parents, or may be the authorities, or what not."
