"In university courses we do exercises. Term papers, quizzes, final examinations are not meant for publication. We move through a course on Dostoevsky or Poe as we move through a mildly good cocktail party, picking up the good bits of food or conversation, bearing with the rest, going home when it comes to seem the reasonable thing to do. Art, at those moments when it feels most like art -- when we feel most alive, most alert, most triumphant -- is less like a cocktail party than a tank full of sharks."
