A Theory of Justice is a 1971 work of political philosophy and ethics by the philosopher John Rawls, in which the author attempts to provide a moral theory alternative to utilitarianism and that addresses the problem of distributive justice (the socially just distribution of goods in a society). The theory uses an updated form of Kantian philosophy and a variant form of conventional social contract theory. Rawls's theory of justice is fully a political theory of justice as opposed to other forms of justice discussed in other disciplines and contexts.
