Famous quotes containing the word history:

    “Social history might be defined negatively as the history of a people with the politics left out.”
    —G.M. (George Macaulay)

    “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)

    “The history of this country was made largely by people who wanted to be left alone. Those who could not thrive when left to themselves never felt at ease in America.”
    —Eric Hoffer (1902–1983)
