“No; we have been as usual asking the wrong question. It does not matter a hoot what the mockingbird on the chimney is singing.... The real and proper question is: Why is it beautiful?”
—Annie Dillard (b. 1945)
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
“A cigarette is the perfect type of a perfect pleasure. It is exquisite, and it leaves one unsatisfied. What more can one want?”
