What is the glue which holds an economy together? Disciples of Adam Smith would argue that self-interest serves as the organising principle. The problem with this way of thinking is that it overlooks the fact that man is not an island unto himself. He is a social animal, who must have constant dealings with other people. Besides, according to John Maynard Keynes, it is impossible to pursue our self-interest rationally, because we don’t have enough information to make probabilistic judgments about the future. Instead, we must rely on irrational animal spirits as a spur to action.
