Good novels are not written by orthodoxy-sniffers, nor by people who are conscience-stricken about their own orthodoxy. Good novels are written by people who are not frightened.
Man is the only creature that consumes without producing. He does not give milk, he does not lay eggs, he is too weak to pull the plough, he cannot run fast enough to catch rabbits. Yet he is lord of all the animals. He sets them to work, he gives back to them the bare minimum that will prevent them from starving, and the rest he keeps for himself.
