 Postmodernism is a highly diverse intellectual and artistic activity, and two branches (for example, postmodern literature and postmodern philosophy) can have little in common.Criticism of postmodernism in general is usually not a comprehensive attack on the various diverse movements labelled postmodern.Such criticism often refers to specific branches of postmodernism, frequently on intellectual theories in the humanities (philosophy, history, gender and LGBT+ studies, structuralism, cultural relativism and "theory").
