Famous quotes containing the words european, avalanche, size and/or table:

    Being human signifies, for each one of us, belonging to a class, a society, a country, a continent and a civilization; and for us European earth-dwellers, the adventure played out in the heart of the New World signifies in the first place that it was not our world and that we bear responsibility for the crime of its destruction.
    Claude Lévi-Strauss (b. 1908)

    The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.
    Aldous Huxley (1894–1963)

    Delusions that shrink to the size of a woman’s glove,
    Then sicken inclusively outwards:
    . . . the incessant recital
    Intoned by reality, larded with technical terms,
    Each one double-yolked with meaning and meaning’s rebuttal:
    For the skirl of that bulletin unpicks the world like a knot....
    Philip Larkin (1922–1986)

    Will you greet your doom
    As final; set him loaves and wine; knowing
    The game is finished when he plays his ace,
    And overturn the table and go into the next room?
    Philip Larkin (1922–1986)
