Book excerpt: Human beings live together in societies which, by their very nature, give rise to institutions governing the behavior and freedom of individuals. This raises important questions about how these institutions ought to function, and the extent to which actual systems of government succeed or fail in meeting these ideals. This Oxford Reader contains 140 key writings on political thought, covering issues about human nature and its relation to society, the extent to which the powers of the State are justified, the tension between liberty and rights, and the way resources should be distributed. Topics such as international relations, minority rights, democracy, socialism, and conservatism are also discussed by contributors ranging from Plato and Aristotle to Foucault, Isaiah Berlin, and Martin Luther King.
