Dialectical logic was the system of laws of thought, developed within the Hegelian and Marxist traditions, that sought to supplement or replace the laws of formal logic. The precise nature of the relation between dialectical and formal logic was hotly debated within the Soviet Union and China. Rather than the abstract formalism of traditional logic, dialectical logic was meant to be a materialistic examination of concrete forms: The logic of motion and change. A logic that is a statement about the objective material world.
