Abstract: Gramsci's philosophy of praxis returns to the dialectical nature of Marxism,establishes an overall organic view such as connection,coherence,generativeness and historicity under the rational dialectics.It examines everything in the organic relationship and dynamic process,which is reflected in the following aspects:The first is to follow the holistic view of dialectics to transcend the binary opposition between the old materialism and the idealism,and insist on the organic unity of subject and object,theory and practice.The second is to regard society as an organism,based on the changed reality of the capitalist society,emphasizing the intersecting of political society and civil society,and the dialectical interaction between economic base and superstructure.The third is to regard the organic intellectuals as the intermediary between the proletarian party and the masses,so as to seize the cultural leadership,and at the same time attach importance to the acquisition of economic and political leadership,and maintaining the totality position of leadership.

Key words: Gramsci, philosophy of praxis, rational dialectics, organicity, historicity
