Materialist dialectic

Dialectical materialism (sometimes abbreviated diamat) is a philosophy of science and nature, based on the writings of Karl Marx and Friedrich Engels, and developed largely in Russia and the Soviet Union. Inspired by dialectic and materialist philosophical traditions, it accepts evolution of the natural world and the emergence of new qualities of being at new stages of evolution. As Z. A. Jordan notes, "Engels made constant use of the metaphysical insight that the higher level of existence emerges from and has its roots in the lower; that the higher level constitutes a new order of being with its irreducible laws; and that this process of evolutionary advance is governed by laws of development which reflect basic properties of 'matter in motion as a whole'."

The formulation of the Soviet version of dialectical and historical materialism in the 1930s by Joseph Stalin and his associates (such as in Stalin's book Dialectical and Historical Materialism) became the "official" Soviet interpretation of Marxism. It was codified and popularized in text books which were required reading in the Soviet Union as well as some Eastern European countries. It was exported to China as the "official" interpretation of Marxism but has since been widely rejected in China in the Soviet formulation.

A Soviet philosophical encyclopedia of the 1960s speaks of the evolution of complexity in nature as follows: "This whole series of forms (mechanical, physical, chemical, biological and social) is distributed according to complexity from lower to higher. This seriation expresses their mutual bonds in terms of structure and in terms of history. The general laws of the lower forms of the motion of matter keep their validity for all the higher forms but they are subject to the higher laws and do not have a prominent role. They change their activity because of changed circumstances. Laws can be general or specific, depending on their range of applicability. The specific laws fall under the special sciences and the general laws are the province of diamat." Each level of matter exists as a type of organization, in which the elements that make up a whole, or system, are marked by a specific type of interconnection.
