Ayn RandNot selfishness, but precisely the absence of a self. Look at them. The man who cheats and lies, but preserves a respectable front. He knows himself to be dishonest, but others think heโs honest and he derives his self-respect from that, second-hand. The man who takes credit for an achievement which is not his own. He knows himself to be mediocre, but heโs great in the eyes of others.
