1885-1971. Hungarian philosopher, one of the founders of `Western' or `Hegelian' Marxism, a philosophy opposed to the Marxism of the official communist movement. In History and Class Consciousness 1923, he argued that the proletariat was the `identical subject-object' of history. Under capitalism, social relations were `reified' (turned into objective things), but the proletariat could grasp the social totality. Lukacs himself repudiated the book and spent much of the rest of his life as an orthodox communist. He also made contributions to Marxist aesthetics and literary theory. He believed, as a cultural relativist, that the most important art was that which reflected the historical movement of the time: for the 20th century, socialist realism.
