Famous quotes containing the words dwarfs and/or white:

    The worth of a State, in the long run, is the worth of the individuals composing it ... a State which dwarfs its men, in order that they may be more docile instruments in its hands even for beneficial purposes—will find that with small men no great thing can really be accomplished.
    John Stuart Mill (1806–1873)

    There is no word for time.
    Today we will
    not think to number another summer
    or watch its white bird into the ground.
