"I realize that all society rests upon force. But all the great creative actions, all the decent human relations, occur during the intervals when force has not managed to come to the front. These intervals are what matter. I want them to be as frequent and as lengthy as possible, and I call them "civilization". Some people idealize force and pull it into the foreground and worship it, instead of keeping it in the background as long as possible. I think they make a mistake, and I think that their opposites, the mystics, err even more when they declare that force does not exist. I believe that it exists, and that one of our jobs is to prevent it from getting out of its box. It gets out sooner or later, and then it destroys us and all the lovely things which we have made. But it is not out all the time, for the fortunate reason that the strong are so stupid."
