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 400 years later, an idea can still change the world.
I've witnessed first hand the power of ideas. I've seen people kill in the name of them, and die defending them ... but you cannot kiss an idea, cannot touch it, or hold it ... ideas do not bleed, they do not feel pain, they do not love...And it is not an idea that I miss, it is a man.
