As for the study of Marxist philosophy in today’s China, there is a tendency of denying the theoretical essence of Marxism in the name of “value neutrality”, together with reflecting on the closure, arbitrariness and dogmatization in the past and emphasizing upon the openness, diversity and individualism. It needs a dialectical analysis to correctly deal with the relationships between theory and reality, academics and ideology, science and ideology, the “party” nature and “class” nature of ideology and make a full understanding of the homogeny and heterogeneity in terms of existence, fact judgment and value judgment in terms of research approaches, academic study and applied research in terms of research levels. In order to unify the theoretical essence and research diversity in the study of Marxist philosophy in China, we shall be vigilant against politically viewing it as a pure ideological doctrine on the one hand and stick to the theoretical core and basic value of Marxism on the other.
