Famous quotes containing the words real, data and/or type:
“The modern American tourist now fills his experience with pseudo-events. He has come to expect both more strangeness and more familiarity than the world naturally offers. He has come to believe that he can have a lifetime of adventure in two weeks and all the thrills of risking his life without any real risk at all.”
—Daniel J. Boorstin (b. 1914)
“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)
“But the mother’s yearning, that completest type of the life in another life which is the essence of real human love, feels the presence of the cherished child even in the debased, degraded man.”
—George Eliot [Mary Ann (or Marian)
