Book excerpt: Uniquely bringing together three different texts, Runciman (Trinity College, U. of Cambridge, UK) elucidates the problems with arguments in Plato's Republic, Hobbes's Leviathan, and Marx's Communist Manifesto, although they are viewed as great books. He focuses on passages that relate to ways to achieve and sustain harmony and order in human societies, and the mistakes they make in their arguments in similar areas. There is no index.
