Famous quotes containing the words observation and/or history:

    One man’s observation is another man’s closed book or flight of fancy.
    Willard Van Orman Quine (b. 1908)

    If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years.
    Josiah Royce (1855–1916)
