“实践”是马克思主义理论的重要范畴和根本原则。作为出发点和基础的实践原则本身就昭示着一种先在性,因为马克思主义哲学是一种实践哲学,是建立在实践基础之上的。而实践原则的先在性不仅体现在对于感性直观上而且也体现在理论层面上。由此分析,要回归马克思主义哲学的本质就必须贯彻实践原则。 “Practice ” is an important category and fundamental principle of Marxist theory. The principle of practice, as the starting point and foundation, shows itself a pre-existing character because Marxist philosophy is a kind of practical philosophy that is based on practice. The preconceived notion of the principle of practice is not only reflected in the intuition and intuition but also at the theoretical level. From this analysis, to return to the essence of Marxist philosophy, we must implement the principle of practice.
