We are told to remember the idea, not the man. Because a man can fail. He can be caught, he can be killed and forgotten. But four hundred years later an idea can still change the world. I've witnessed firsthand the power of ideas. I've seen people kill in the name of them; and die defending them. But you cannot touch an idea, cannot hold it or kiss it. An idea does not bleed, it cannot feel pain, and it does not love.
