On February 24-25, 1956, in a closed session of the 20th Congress of the Communist Party of the Soviet Union, Nikita S. Khrushchev made his now famous speech on the crimes of the Stalin era. That speech marked a break with the past and it marked the end of what J.M. Bochenski dubbed the "dead period" of Soviet philosophy. Soviet philosophy changed abruptly after 1956, especially in the area of dialectical materialism. Yet most philosophers in the West neither noticed nor cared. For them, the resurrection of Soviet philosophy, even if believable, was of little interest. The reasons for the lack of belief and interest were multiple.
