Famous quotes containing the words wiener and/or index:

    The idea that information can be stored in a changing world without an overwhelming depreciation of its value is false. It is scarcely less false than the more plausible claim that after a war we may take our existing weapons, fill their barrels with cylinder oil, and coat their outsides with sprayed rubber film, and let them statically await the next emergency.
    —Norbert Wiener (1894–1964)

    Exile as a mode of genius no longer exists; in place of Joyce we have the fragments of work appearing in Index on Censorship.
    Nadine Gordimer (b. 1923)
