如果说“商品”是马克思主义政治经济学的起始范畴,那么,“实践”则是马克思主义哲学的起始范畴。这是因为实践具有客观实在性、主观目的性、社会性和历史性四方面的属性,兼有普遍规定性和直接现实性的双重品格。由此,它内在地包含着多种矛盾,比如主体与客体、主观与客观、个人与社会等。这些矛盾和特点使它作为马克思主义哲学的起始范畴成为可能。马克思主义哲学的本体论、认识论、历史辩证法、社会结构理论、群众史观及其价值灵魂都与实践有着内在的密切相关性。 If we say that “commodity” is the starting point of Marxist political economy, then “practice” is the starting point of Marxist philosophy. This is because the practice possesses the attributes of objective reality, subjective purpose, sociality and historicity, with the dual character of universality and direct reality. Therefore, it inherently contains a variety of contradictions, such as the subject and object, subjective and objective, individuals and society. These contradictions and characteristics make it possible as the starting point of Marxist philosophy. The ontology, epistemology, dialectics of history, theory of social structure, the concept of mass history and the soul of value of Marxist philosophy are intrinsically closely related to practice.
