The author says that, “what was our culture lost in 1980 that the avant-garde had in 1890? Ebullience, idealism confidence, the belief that that there was plenty of territory to explore, and above all the sense that art, in the most disinterested and noble way, could find the necessary”. What cause the culture in 1980 to lose all of those qualities in art? How does modernism take away all the quality from art?
