"Art for Art's Sake" is a philosophical concept that suggests art should exist for its own purpose, rather than to serve a moral, political, or utilitarian function. This idea emphasizes the intrinsic value of art, arguing that its beauty and emotional impact are enough justification for its creation and appreciation. The phrase became popular in the 19th century, particularly associated with the Aesthetic Movement and figures like Oscar Wilde. Proponents believed that art should be free from societal constraints and should not be judged based on its ability to convey messages or provoke thought, but rather on its aesthetic qualities alone.
