Systems theory
This project started after the critical reception of Habermas's book "Knowledge and Human Interests" (1968), after which Habermas chose to move away from contextual and historical analysis of social knowledge toward what would become the theory of communicative action. The theory of communicative action understands language as the foundational component of society and is an attempt to update Marxism by "drawing on Systems theory (Luhmann), developmental psychology (Piaget, Kohlberg), and social theory (Weber, Durkheim, Parsons, Mead, etc.)".
