"[I]n its compactness and objectivity the book is a useful theoretical tool for proletarian class aspirations, we cannot in reviewing it do better than to indicate, though inadequately, its richness and value."<br /><b>—Paul Mattick</b><br /><p>“The republication of Karl Korsch’s masterly study of Karl Marx provides a useful reminder of the theoretical insights of the author, made during a period of major upheaval and debate among the then faltering international communist and workers movements. The book provides, not only an in-depth examination of Marx’s core ideas and work, it is also to be viewed in many ways as a summary of much of Korsch’s understanding of Marx and Marxism. Ideas such as the principle of historical specification and Korsch’s own understanding of dialectics, political economy and historical materialism feature prominently.” –Liam Conway, <em>Marx & Philosophy Review of Books</em></p>
