In art, postmodernism refers to a reaction against modernism. It is less a cohesive movement than an approach and attitude toward art, culture, and society. 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. Postmodern art can be also characterized by a deliberate use of earlier styles and conventions, and an eclectic mixing of different artistic and popular styles and mediums.
