“Art for art's sake" is the usual English rendering of a French slogan from the early 19th century, "l'art pour l'art", and expresses a philosophy that the intrinsic value of art, and the only "true" art, is divorced from any didactic, moral, or utilitarian function. Such works are sometimes described as "autotelic", from the Greek autoteles, "complete in itself", a concept that has been expanded to embrace "inner-directed" or "self-motivated" human beings.
