Since reform and opening-up began in 1978, Chinese Marxist philosophy has undertaken the double mission of enhancing the emancipation of the mind in society and of realizing its own ideological emancipation. It has gone through an evolutionary process from “extensive discussion about the criterion of truth” to “reform of philosophical textbooks”; from the proposal of the philosophical conception of “practical materialism” to reflection on “modernity”; and from the carrying-out of dialogues among Chinese, Western, and Marxist philosophies to the exploration of “new forms of civilization.” Chinese Marxist philosophy has shifted its way of doing research with practical materialism as a core conception, and it changed such modes of thinking as the intuitive theory of reflection based on na?ve realism, the theory of linear causality based on mechanical determinism, and the reductionism of essence based on abstract substantialism. As a result, it has boosted changes that were already underway in Chinese philosophy, worldviews, theories of truth, conceptions of history, and views of development, and it has further endowed the discourse system of Marxist philosophy with laudable subjectivity and originality.
