“But aesthetic value does not rise from the work's apparent ability to predict a future: we do not admire Cézanne because of the Cubists drew on him. Value rises from deep in the work itself - from its vitality, its intrinsic qualities, its address to the senses, intellect, and imagination; from the uses it makes of the concrete body of tradition. In art there is no progress, only fluctuations of intensity. Not even the greatest doctor in Bologna in the 17th century knew as much a bout the human body as today's third-year medical student. But nobody alive today can draw as well as Rembrandt or Goya.”
