Famous quotes containing the words comparison and/or tables:

    “But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.”
    —Ralph Waldo Emerson (1803–1882)

    “The evening falters. Couples in their coats
    Are leaving gaps already, and the rest
    Move tables closer.”
    —Philip Larkin (1922–1986)
