Famous quotes containing the words comparison of, comparison and/or stream:

    “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)

    “I have travelled a good deal in Concord; and everywhere, in shops, and offices, and fields, the inhabitants have appeared to me to be doing penance in a thousand remarkable ways.... The twelve labors of Hercules were trifling in comparison with those which my neighbors have undertaken; for they were only twelve, and had an end; but I could never see that these men slew or captured any monster or finished any labor.”
    —Henry David Thoreau (1817–1862)

    “When cats run home and light is come,
    And dew is cold upon the ground,
    And the far-off stream is dumb,
    And the whirring sail goes round,
    And the whirring sail goes round;
    Alone and warming his five wits,
    The white owl in the belfry sits.”
    —Alfred Tennyson (1809–1892)
