This volume bases a clear and unbiased account of Communist philosophy on the Marxian Materialist Concept of History and Marxian Theory of Value. The spear-head of Marxism is its doctrine of class-struggle and from this Laski sets out on in his exposition of the Communist attitude.

Although first published in 1927, the intervening years have in no way detracted from the intrinsic value of this enlightening study, regarded by many as the essential textbook for the understanding of this subject.
