Postmodernism is a broad movement that developed in the mid- to late 20th century across philosophy, the arts, architecture, and criticism, marking a departure from modernism. The term has been more generally applied to describe what postmodernists believe to be the historical era following modernity and the tendencies of this era.
While encompassing a wide variety of approaches and disciplines, postmodernism is generally defined by an attitude of skepticism, irony, or rejection of the grand narratives and ideologies of modernism, often calling into question various assumptions of Enlightenment rationality. Consequently, common targets of postmodern critique include universalist notions of objective reality, morality, truth, human nature, reason, science, language, and social progress. Postmodern thinkers frequently call attention to the contingent or socially-conditioned nature of knowledge claims and value systems, situating them as products of particular political, historical, or cultural discourses and hierarchies. Accordingly, postmodern thought is broadly characterized by tendencies to self-referentiality, epistemological and moral relativism, pluralism, and irreverence.
Postmodern critical approaches gained purchase in the 1980s and 1990s, and have been adopted in a variety of academic and theoretical disciplines, including cultural studies, philosophy of science, economics, linguistics, architecture, feminist theory, and literary criticism, as well as art movements in fields such as literature, contemporary art, and music. Postmodernism is often associated with schools of thought such as deconstruction, post-structuralism, and institutional critique, as well as philosophers such as Jean-François Lyotard, Jacques Derrida, and Fredric Jameson.
Criticisms of postmodernism are intellectually diverse, and include assertions that postmodernism promotes obscurantism, is meaningless, and that it adds nothing to analytical or empirical knowledge.
