This is the first detailed study, following the recent collapse of political Marxism in Eastern Europe, of twentieth-century Hungarian philosopher Georg Lukács and his position as the leading proponent of the Marxist theory of reason. Lukács's History and Class Consciousness has been called one of the three most influential philosophical works of this century, and he, the outstanding Marxist philosopher. Marxism has long suffered relative neglect in philosophical discussion as a result of its own invidious distinction between itself and the supposed irrationality of what it regards as bourgeois philosophy.

Tom Rockmore offers a uniquely detailed philosophical analysis of Lukács's entire position as a theory of reason, based on the distinction between reason and unreason, or irrationalism. The author gives special emphasis to Lukács's connection to German neo-Kantianism, particularly Lask, and on his last, unfinished work.

Rockmore begins with an account of the roots of Lukács's Marxism, followed by an in-depth analysis of his often mentioned, but still incompletely understood, seminal essay "Reification and the Class Consciousness of the Proletariat." He then traces the evolution and later demise of the distinction between reason and irrationalism in Lukács's final thought. The author thus makes available for the first time in English a strictly philosophical discussion of Georg Lukács's Marxist phase and brings consideration of his thought into the wider philosophical discussion.
