Famous quotes containing the words objects and/or earth:

    Nobody seriously questions the principle that it is the function of mass culture to maintain public morale, and certainly nobody in the mass audience objects to having his morale maintained.
    Robert Warshow (1917–1955)

    The earth had a single light afar,
    A flickering, human pathetic light,
    That was maintained against the night,
    It seemed to me, by the people there,
    With a Godforsaken brute despair.
    Robert Frost (1874–1963)
