One‐dimensional criticism: a Marcusean reflection on Habermas's critical theory1

This paper explores the metaphysical foundations of critical theory in Marcuse and Habermas's postmetaphysical alternative. It argues that Habermas's attempt to free critical theory from a normative conception of life‐activity deprives it of the conceptual tools required to accurately diagnose the fundamental structure of social problems today. It thus concludes that Marcuse's efforts towards specifying a life‐grounded foundation to critical theory must be renewed if the project of human freedom is to be advanced today.
