This quality embodies the quality of Marxist theory. It lies in its thorough scientific nature, firm revolutionary nature and conscious practicality, and thorough scientific nature is the most fundamental. The fundamental reason why Marxism can last forever and maintain its youthful vitality is that it is completely scientific. The thoroughness of science is closely related to the progress of theory. Keeping pace with the times in theory is an inevitable requirement of science.
law of development
This quality is the concrete embodiment of human understanding and development law. Persisting in proceeding from reality, seeking truth from facts and testing and developing truth in practice are the basic requirements for human beings to understand the law of development. If this requirement is violated, knowledge will be divorced from the changing objective reality and lose the truth.
Marxist classical writers never think that their theories are immutable, but always demand to enrich and develop their theories according to the development of practice and the changes of the times. Keeping pace with the times is a cognitive process in which Marxism respects and follows objective laws according to the changes in practice and constantly surpasses its predecessors and itself. Therefore, understanding the law, grasping the law, following the law and applying the law are the fundamental requirements.
