“Marxism is the science of the laws governing the development of nature and society, the science of the revolution of the oppressed and exploited masses, the science of the victory of socialism in all countries, the science of building communist society. As a science, Marxism cannot stand still, it develops and is perfected. In its development, Marxism cannot but be enriched by new experience, new knowledge — consequently some of its formulas and conclusions cannot but change in the course of time, cannot but be replaced by new formulas and conclusions, corresponding to the new historical tasks. Marxism does not recognize invariable conclusions and formulas, obligatory for all epochs and periods. Marxism is the enemy of all dogmatism.”

J. Stalin
