Do you think... that men have always massacred each other, as they do today? Have they always been liars, cheats, traitors, brigands, weak, flighty, cowardly, envious, gluttonous, drunken, grasping, and vicious, bloody, backbiting, debauched, fanatical, hypocritical, and silly?
It requires twenty years for a man to rise from the vegetable state in which he is within his mother's womb, and from the pure animal state which is the lot of his early childhood, to the state when the maturity of reason begins to appear. It has required thirty centuries to learn a little about his structure. It would need eternity to learn something about his soul. It takes an instant to kill him.
Men must have somewhat altered the course of nature; for they were not born wolves, yet they have become wolves.
