- (in Marxist theory) the doctrine that all forms of social thought, as art or philosophy, and institutions, as the family or the state, develop as a superstructure founded on an economic base; that they reflect the character of economic relations and are altered or modified as a result of class struggles; that each ruling economic class produces the class that will destroy or replace it; and that dialectical necessity requires the eventual withering away of the state and the establishment of a classless society: the body of theory, in dialectical materialism, dealing with historical process and social causation.
- the part of Marxist theory maintaining that social structures derive from economic structures and that these are transformed as a result of class struggles, each ruling class producing another, which will overcome and destroy it, the final phase being the emergence of a communist society
