The dialectical materialism and historical materialism of Marxism are not only its world outlook, but also its methodology.
It is embodied in methods starting from practice, social system research methods, social contradiction analysis methods, social subject research methods, social process research methods, social cognition and evaluation methods, world history research methods, etc. There are also logical and historically consistent methods, inductive and deductive methods, analytical and comprehensive methods, abstract and concrete methods, the dialectical method of unification of subject and object, the research method of historical synergy, the method of unification of “human” and “material”, etc.
Marxist methodology of social science is a creative and open system. Marxism should actively learn from and absorb all reasonable methods created by human beings in social cognition and social practice.
