Famous quotes containing the words large and/or systems:
“The best hopes of any community rest upon that class of its gifted young men who are not encumbered with large possessions.... I now speak of extensive scholarship and ripe culture in science and art.... It is not large possessions, it is large expectations, or rather large hopes, that stimulate the ambition of the young.”
—Rutherford Birchard Hayes (1822–1893)
“We have done scant justice to the reasonableness of cannibalism. There are in fact so many and such excellent motives possible to it that mankind has never been able to fit all of them into one universal scheme, and has accordingly contrived various diverse and contradictory systems the better to display its virtues.”
—Ruth Benedict (1887–1948)
