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)
“Clay answered the petition by declaring that while he looked on the institution of slavery as an evil, it was ‘nothing in comparison with the far greater evil which would inevitably flow from a sudden and indiscriminate emancipation.’”
—State of Indiana, U.S. public relief program (1935-1943)
“Verily, a polluted stream is man. One must actually be a sea to take in a polluted stream without becoming impure. Behold, I teach you the superman: he is the this sea, in him can your great contempt go under.”
—Friedrich Nietzsche (1844–1900)
