This is one of the most respected books on Marx's philosophical thought. Wood explains Marx's views from a philosophical standpoint and defends him against common misunderstandings and criticisms. All the major philosophical topics in Marx's work are considered: the central concept of alienation; historical materialism and Marx's account of social classes; the nature and social function of morality; philosophical materialism and Marx's atheism; and Marx's use of the Hegelian dialectical method and the Marxian theory of value. This second edition has been revised to include a new chapter on capitalist exploitation and new suggestions for further reading. Wood has also added a substantial new preface which looks at Marx's thought in light of the fall of the Soviet Union and our continued ambivalence towards capitalism, exploring Marx's continuing relevance in the twenty-first century.
