Of these two identically titled books, Professor Fainsod's is far and away the more substantial and scholarly. Seeking to analyze the physiology as well as the anatomy of Soviet totalitarianism, the author briefly traces the development of the system and settles down to a careful examination of the rôle of the Communist Party, the instruments by which the system is ruled and directed, and the tensions produced by such a system. The Kolarz study, intended only as a popular introduction, is based on a series of B.B.C. broadcasts.
