"Superman is invincible, and Superman is the first super-being to come into literary life. There he is alone. That's the way I see him. If I were a Superman among two billion people, despite the fact that I was a super-being, I'd feel pretty insecure. For instance, say I was a white hunter in Africa and I were to walk into a cannibal village. Despite the fact that I had a gun and they didn't, despite the fact that I had ammunition and they didn't, I'd feel pretty insecure, despite the fact that I could probably shoot my way out. Superman is alone in our world."
