[For Marx and Human Nature] This remarkable short book deserves to be widely read and not only by those interested in Marxology. For it achieves something rare in its field: rationally compelling proof. Not only does it conclusively refute a widely current legend about Marx's thought . it does so with striking elegance, economy, and argumentative power.
Times Literary Supplement
[For The Legacy of Rosa Luxembourg] This is a useful and thoughtful book, in which the power and originality of Rosa Luxemburg's thinking emerges."
