The concepts of “reform” and “revision” need considerable elaboration before a systematic study of their political ramifications can be undertaken. Common usage in the West seems to indicate that “reform” in communist systems means change towards political pluralism, less ideology, and greater participation by the citizenry in political communication, aggregation, and decision-making. “Revision” and “revisionism,” which are essentially communist concepts, are also interpreted to indicate a process of “loosening up” the autocratic, bureaucratic, and ideological nature of contemporary political and socio-economic systems in Eastern Europe and the Soviet Union.
