Originally published in 1952. This book collects numerous works on the revival of Spinoza scholarship in the Soviet Union during the 1920s and 30's, including the emergence of conflicting Marxist schools of Spinoza interpretation. This work includes translations by Kline of seven major articles on Spinoza published from 1923-1932, with a lengthy introduction providing contextual references. These developments were generally unknown outside of Russia due to lack of prior translations into a Western European language. The Marxist view of Spinoza represents a break not only with the dominant traditions of Western scholarship, but also with those critical and negative views of pre-Revolutionary Russia. This book provides both the study of Spinoza in Soviet philosophy, and of Soviet philosophy through Spinoza.
