Schopenhauer's aesthetics were directly responsible for the rise of the Symbolists and their allied movements, and to the general development of the concept of art for art's sake. It deeply influenced the aesthetics of Friedrich Nietzsche, although he ultimately rejected Schopenhauer's conception of Will as evil, whose famous opposition of the Apollonian and Dionysian is a translation of Schopenhauer's opposition of intellect against will in terms of Greek mythology. When the Marxist critique of capitalism was stirred into the aesthetic stew, Schopenhauer's essentially ascetic view of the purpose of art laid the foundation for the opposition of kitsch versus the avant-garde which is found in such critics as Clement Greenberg. Contemporary beliefs that artistic creation should not be swayed by financial gains or the demands of patrons or customers, and the belief that the greatest artists are those who create new and entirely unprecedented forms of expression, rather than those who develop already existing forms, all owe a great deal to the influence of Schopenhauer.
