The dialectical method, popularized by Plato’s characterization of Socrates, and then updated by Hegel and Marx, is often thought of as a three-step process: person/group A proposes a thesis P, person/group B offers an anti-thesis that contradicts it ~P, and then there is a synthesis of the two that results in a new thesis Y. Hegel introduced the idea that the thesis contains within itself its own antithesis, that a thesis contains contradictions that must be worked out in a process that repeats through multiple aufheben until we arrive at the Absolute. Marx took this and applied it to history: the material conditions of an age contains its own contradictions that must be worked out in a process that eventually leads to a classless, stateless utopia known as communism.

Critical Theory is a methodology of critiquing power relations within society. It takes as axiomatic the new-Marxist analysis of oppressor-oppressed dynamics being inherent in all human relationships. As such, Critical Theory is not about whether such power dynamics exist, but in what ways they manifest. There is little talk about why these dynamics manifest.
