Contradiction dialectics is contradictory category for theoretic axis of dialectics,and it has two levels,i.e."ontology" and "the methodology".The ontology contradiction dialectics is an occluded in contradiction ontological level and rejects "convergence" concept,the lack of dialectics,and its theoretical methodology miss is: theoretical origin dislocation,departure from Marx’s concept of harmony;Theory element is missing,omissions of fusions of the opposite;Do not admit fusion is the driving force;Attitudes of treating contradictory are wrong,giving up contradiction movement control;Resolving contradictions methodology is distorted,and resolving conflicts methodology is vacant,misleading people to take the objective existence of the struggle between opposites nature into people’s value goal diligently,and breeding the fighting philosophy.The ontology contradiction dialectics shall be ended,while contradiction dialectics shall be refreshed,and new paths shall be realized from ontology to methodology.Thus,it is a need to have a thorough study of Marx’s dialectics texts,introduce the theoretical elements of fusions of the opposite and grasp Marxist dialectics from the source comprehensively and accurately.It is also a need to absorb the rational core of "harmony" thinking of Chinese philosophy,and take the road of the sinicization of Marxist dialectics.Combining the actual reality of building a socialist harmonious society with the changes of themes of the contemporary world,it is a need to make Marxist dialectics into a contemporary one.Contradiction dialectics is on its new way,and the end of the new road of Marxist dialectics is the establishment of Marxist harmonious dialectics.
