This book responds to the need for a retrieval and renewal of the work of Karl Marx through close philosophical analysis of his publications, manuscripts, and letters - especially those relevant to politics, morality, and the future. This philosophical study stands out because of its two principal features. First, it reviews and develops ideas about the future, though often only briefly discussed by Marx and his commentators, drawn from Marx's work. Second, it focuses on collective matters that are critical for Marx's ideas but rarely investigated and still problematic. Part One introduces Marx with a discussion of emancipation and freedom in community. It then discusses the importance of retrieval and the methodology for promoting it. Part Two is about misunderstandings of Marx's ideas about productive development, division of labour, and organisations. Part Three discusses nations, morality, and democracy, all of which Marx supported. Part Four takes up Marx'ssignificant, but misunderstood, ideas about the future and his relation to the anarchists.
