Famous quotes containing the words large and/or systems:
“Men have broad and large chests, and small narrow hips, and more understanding than women, who have but small and narrow breasts, and broad hips, to the end they should remain at home, sit still, keep house, and bear and bring up children.”
—Martin Luther (1483–1546)
“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)
