A pattern of change that begins with some state of affairs (‘thesis'); which then is overturned because of its own contradictions, giving rise to its opposite (‘antithesis'); and which then reaches an equilibrium where the best features of the original state of affairs are preserved (‘synthesis'). Marx argues that historical change is dialectical: each stage of class society contains contradictions that lead to its overthrow, yet this series of revolutions is progressive.
