Of all the miserable, unprofitable, inglorious wars in the world is the war against words. Let men say just what they like. Let them propose to cut every throat and burn every house - if they so like it. We have nothing to do with a man's words or a man's thoughts, except to put against them better words and better thoughts, and so to win in the great moral and intellectual duel that is always going on, and on which all progress depends.
