Famous quotes containing the words extinction and/or event:

    I wish all men to be free. I wish the material prosperity of the already free which I feel sure the extinction of slavery would bring.
    Abraham Lincoln (1809–1865)

    I feared these present years,
    The middle twenties,
    When deftness disappears,
    And each event is
    Freighted with a source-encrusting doubt,
    And turned to drought.
    Philip Larkin (1922–1986)
