The difference between dialectical materialism and historical materialism;

1, dialectical materialism

Dialectical materialism (that is, modern materialism) is a set of systematic logical theoretical thinking forms created by Karl Marx and Friedrich von Engels who critically absorbed the' reasonable core' of German classical philosophy-the' basic core' of Hegel's dialectics and Feuerbach's mechanical materialism, and summarized natural science, social science and thinking science.

Dialectical materialism (dialectical materialism) is a Marxist philosophical theory and a scientific world outlook with the organic unity of materialism and dialectics. /kloc-produced in the 0/9 s. This is an advanced form of materialism. Dialectical materialism holds that the world is essentially material. Engels said: "The real unity of the world lies in its materiality". (Anti-Turin Theory, Selected Works of Marx and Engels, Volume III, page 83) Matter is primary, while consciousness is secondary. Consciousness is a highly developed material-the function of the human brain, and it is the reflection of the objective material world in the human brain. Dialectical materialism holds that the material world moves, changes and develops according to its own internal laws. "Everything is divided into two." It reveals that the fundamental reason for the development of things lies in the contradictions within things. Both sides of the contradiction of things are unified and struggling, which promotes the continuous development of things from low level to high level. Therefore, the contradictory law of things, that is, the law of unity of opposites, is the most fundamental law of the movement, change and development of the material world.

Historical materialism is a philosophical theory about the general law of human social development, an important part of Marxist philosophy, a scientific view of social history and a general methodology for understanding and transforming society, also known as historical materialism.
