Step-by-step explanation:
Postmodernism, also spelled post-modernism, in Western philosophy, a late 20th-century movement characterized by broad skepticism, subjectivism, or relativism; a general suspicion of reason; and an acute sensitivity to the role of ideology in asserting and maintaining political and economic power.
Its main characteristics include anti-authoritarianism, or refusal to recognize the authority of any single style or definition of what art should be; and the collapsing of the distinction between high culture and mass or popular culture, and between art and everyday life.
