Egoism is often seen as the opposite of altruism, meaning the concern for others. "Altruism" is a word created by the French thinker Auguste Comte, who says that people must only serve each other and never be egoistic. The German thinker Friedrich Nietzsche instead says that altruism is not the opposite of egoism. He also says that even though people altruism is good, they do not treat each other well very much at all. Other egoists also often criticise this kind of attitude against people who do what benefits themselves. But Nietzsche says that people should eventually leave both altruism and egoism behind.
