Systems Theory and Postmodernism

Luhmann argues that society equals communication, not narratives, norms, shared memories, etc. Thus, according Luhmann, there has been no actual postmodern change because society still consists of communication. Postmodernism is a theory of culture; however, Luhmann displays little interest in culture. So it’s not that Luhmann refuted Lyotard, he simply wasn’t interested in the theory.
