The renaissance of ontology and the shift in the existentialism have become a major subject in the contemporary Marxian studies. Various ontological theories have come into being under the Marxist rubric, composing a major challenge to studies in Marxist philosophy. There is no need to go to the ontological level when one identifies the real foundation of practice and conflicts out there, which would outshine any effort to reconstruct ontology. A love to regard ontology as a matter of ultimacy would empower ontology with the absolute right of explanation and encourage an equally absolutist mode of thinking.
How to ascertain and grasp the basic characters of Marx’s philosophy and theoretical characteristics according to his internal unity of ideological system? How to judge Marx’s philosophical revolution transcending the previous era of philosophy and its historical significance? It is the integrity of political economy,socialist theory and philosophy that is the fundamental framework for grasping the basic thought of Marxist philosophy.The major study subjects in the whole life of Marx are the actual movements and theoretical dimensions replacing old social formations by the new one through transcending the private ownership,which at the same time are manifestations of the transformation from the slavery state of the people to their liberation.The criticism suffered by the current study of Marxist philosophy has its origins in the lack of the study of academic tradition and problem consciousness of Marx’s philosophy.
