This book is a critique of political essentialism, the doctrine that states that there is a single nature and destiny for human kind and that an elite is indispensable for bringing this about through political action. A systematic value philosophy is contrasted with ideological politics which includes novel theories of justice, freedom, equality and their relation. This book argues against Marxist accounts of social changes, and that the cause of modern revolutions and their aftermath is ideology and not economic factors. Ideology is articulated by political intellectuals who direct political movements. It also argues against ideologically based political thought.
