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)

    The principal office of history I take to be this: to prevent virtuous actions from being forgotten, and that evil words and deeds should fear an infamous reputation with posterity.
    Tacitus (c. 55–c. 120)

    When the coherence of the parts of a stone, or even that composition of parts which renders it extended; when these familiar objects, I say, are so inexplicable, and contain circumstances so repugnant and contradictory; with what assurance can we decide concerning the origin of worlds, or trace their history from eternity to eternity?
    David Hume (1711–1776)
