In this work Sidney Hook, a distinguished scholar, examines the chief issues which have divided Marxists from non-Marxists, and Marxists from each other. This volume of exposition, comment and readings is offered as an introduction to the study of Marxism in conflicting theory and practice. A valuable collection of original source readings are provided, including "The Communist Manifesto", "Historical Materialism," "The Fetishism of Commodities," "Religion and Economics," and much more by Marx, Engels, Lenin, Stalin, Kautsky, Trotsky and Luxemburg.-Print ed.
