"I don't enjoy playing chess. Do you know why not? Because it was a game that was born during a brutal age, when life counted for little. And everyone believed that some people were worth more than others.
Kings and pawns...
I don't think that anyone is worth more than anyone else. If you remember nothing else, please remember this. Chess is just a game. Real people aren't pieces. And you can't assign more value to some of them than to others. Not to me. Not to anyone. People are not a thing that you can sacrifice. The lesson is that anyone who looks on the world as if it was a game of chess deserves to lose."
