“Passion!” the professor declares. “They had more passion than those who resisted them. A passion to rule, to tear down society and remake it more to their liking, a passion to silence all dissent and to make a world in which they wouldn’t have to hear an opinion at variance with their own. The passion for destruction always has more appeal to more people than does the passion to preserve and build. It’s an ugly truth of human nature. Passion, sir. The kind of raw passion that breeds ruthlessness.”
