Abstract

For centuries, moral philosophers have attempted to clarify the relationship between morality and rational self-interest. They have been especially interested in the possibility that there are situations in which it is perceptibly against one’s interests to act morally, e.g., situations in which it clearly pays to lie, cheat, or steal. Hobbes, who held an egoistic view of human nature, was especially troubled by this possibility. For if psychological egoism is true and this possibility is a real one, there may be situations in which people must act in a way that is either immoral or irrational. To avoid this unpalatable conclusion, Hobbes seeks to show that the aforementioned possibility is illusory, that no real conflict between morality and rational prudence can occur.
