Karl Marx's Theory of History: A Defence is a 1978 book by the philosopher G. A. Cohen, the culmination of his attempts to reformulate Karl Marx's doctrines of alienation, exploitation, and historical materialism. Cohen, who interprets Marxism as a scientific theory of history, applies the techniques of analytic philosophy to the elucidation and defence of Marx's materialist conception of history.The work for which Cohen is best known, Karl Marx's Theory of History helped to establish analytical Marxism and was awarded the Isaac Deutscher memorial prize. Cohen's interpretation of Marx runs counter to most forms of twentieth-century Marxism, and has been criticised as a form of technological determinism. Source: Wikipedia (en)
