Basic meaning

Practice has many meanings. The classic view is that the subjective view is related to the objective, including the necessity of the objective to the subjective and the necessity of the subjective to the objective.

In short, practice includes three basic aspects: production practice (the active activity of transforming the objective world to satisfy human production) and the practice of dealing with social relations (the purpose of adjusting and reforming social relations between people) Activities) Scientific practice reveals in Engels's natural philosophy that human thought is generated from labor, that is, human subjective consciousness is generated from human practical behavior, and at the same time, human subjective consciousness reacts on objective existence.

In Marx, it mainly emphasizes people’s social practice, the social nature of practice, and the historical and class nature of productive forces in people’s social consciousness. They are all material and dialectical.

Human subjective and objective existence are both material. Subjectivity and objectivity are epistemological. The difference is the definition of internal and external relationships relative to practice. The theory of practice is based on the overall understanding of materialism and dialectics.

"On Practice" emphasizes the development of subjective and objective contradictions in practice and the cognitive development process of understanding and re-practicing. Understanding rises to the guiding role of theory. In contemporary times, emphasis has been placed on the practical standard of truth, which includes the discovery, testing, and realization of truth, which can be seen objectively.
