Don Juan monologue (Act 3) — Man and Superman

Never fear! the white laborer shall have his turn too. But I am not now defending the illusory forms the great ideas take. I am giving you examples of the fact that this creature Man, who in his own selfish affairs is a coward to the backbone, will fight for an idea like a hero. He may be abject as a citizen; but he is dangerous as a fanatic. He can only be enslaved whilst he is spiritually weak enough to listen to reason. I tell you, gentlemen, if you can show a man a piece of what he now calls God's work to do, and what he will later on call by many new names, you can make him entirely reckless of the consequences to himself personally.
