Famous quotes containing the word history:

    They are a sort of post-house,where the Fates
    Change horses, making history change its tune,
    Then spur away o’er empires and o’er states,
    Leaving at last not much besides chronology,
    Excepting the post-obits of theology.
    George Gordon Noel Byron (1788–1824)

    We have need of history in its entirety, not to fall back into it, but to see if we can escape from it.
    José Ortega Y Gasset (1883–1955)

    One classic American landscape haunts all of American literature. It is a picture of Eden, perceived at the instant of history when corruption has just begun to set in. The serpent has shown his scaly head in the undergrowth. The apple gleams on the tree. The old drama of the Fall is ready to start all over again.
    Jonathan Raban (b. 1942)
