Postmodernism is a philosophical movement evolved in reaction to modernism, the tendency in contemporary culture to accept only objective truth and to be inherently suspicious towards a global cultural narrative or meta-narrative. Postmodernist thought is an intentional departure from the previously dominant modernist approaches. The term "postmodernism" comes from its critique of the "modernist" scientific mentality of objectivity and the progress associated with the Enlightenment.
Postmodernism postulates that many, if not all, apparent realities are only social constructs and are therefore subject to change. It emphasises the role of language, power relations, and motivations in the formation of ideas and beliefs. In particular it attacks the use of sharp classifications such as male versus female, straight versus gay, white versus black, and imperial versus colonial; it holds realities to be plural and relative, and to be dependent on whom the interested parties are and of what their interests consist. It supports the belief that there is no absolute truth and that the way in which different people perceive the world is subjective. Postmodernism has influenced many cultural fields, including religion, literary criticism, sociology, linguistics, architecture, history, anthropology, visual arts, and music.
Modernism and postmodernism are understood as a cultural stance or set of perspectives. "Postmodernism" is used in critical theory to refer to a point of departure for works of literature, drama, architecture, cinema, journalism, and design. It has also influenced marketing, business and the interpretation of law, culture, and religion in the late 20th and early 21st centuries. Postmodernism, particularly as an academic movement, can be understood as a reaction to modernism in the Humanities. Whereas modernism was primarily concerned with principles such as identity, unity, authority, and certainty, postmodernism is often associated with difference, plurality, textuality, and scepticism.
