Communism works in theory but not in practice! A theory is an identification of the facts of reality and/or of guidelines for human action... ...a good theory is a true theory, one that recognizes all the relevant facts, including the facts of human nature, and integrates them into a noncontradictory whole. Such a theory has to work in practice. If a man's course of action, thanks to his scrupulous use of logic, derives from a study of reality, then that course must be in harmony with reality. If so, what would prevent it from succeeding?
