This is Hayek's major statement of political philosophy: he shows that the naive application of scientific methods to culture and education has been harmful and misleading, creating not an age of reason and culture, but of superstition an error. He argues for the rejection of Marx, Freud, logical positivism and political egalitarianism, and of the folly of an illusion of social justice. In this paperback all three volumes of Hayek's comprehensive study on the basic principles of the political order of a free society are combined. The first part, Rules and Order, deals with the basic conceptions necessary for a critical analysis of prevailing theories of justice and of conditions which a constitutions securing personal liberty would have to satisfy. The Mirage of Social Justice continues with a critical analysis of the theories of utilitarianism and legal positivism, and of the concept of social justice.
