The process of Marxist philosophy Sinicization embodies the unity of momentum (Shi) and the reason (Li) of Chinese society.The intellectuals who stand for the spirit of Chinese era,not only conceived the reason (Li) of Marxist philosophy Sinicization but also changed the Chinese situation through applying the reason (Li).The philosophies of Mao Ze-dong and Deng Xiao-ping were the outcome of the process.At the same time,the problems of Marxist philosophy arose from the events (Shi) which have happened in the past rime.Because in order to resolve the real problems of Marxist philosophy,we must face the present events (Li) which is varying every where and every time.When we reflect on the process of Marxist philosophy Sinicization,we can find that the momentum (Shi) of history is the root,the reason (Li) of history is reflective,the events (Li) of history is being.These three are influencing each other and so promoting the process of Marxist philosophy Sinicization.
