Karl Kautsky's 1924 review of Karl Korsch’s Marxism and Philosophy appears below in English for the first time. It is hoped that other reviews of Marxism and Philosophy will also be made available in the very near future, not least by leading German communists such as August Thalheimer. Given the highly disputed theoretical legacy of both Kautsky and Korsch, the publication of this review will doubtless add to the debate on the idea of a "coming of age" of Marxism in the late 1860s.
