They say you are not you except in terms of relation to other people. If there weren't any other people there wouldn't be any you because what you do, which is what you are, only has meaning in relation to other people.
Robert Penn WarrenThe end of man is knowledge, but there is one thing he can't know. He can't know whether knowledge will save him or kill him. He will be killed, all right, but he can't know whether he is killed because of the knowledge which he has got or because of the knowledge which he hasn't got and which if he had it, would save him.
