Famous quotes containing the words large and/or systems:
“If the hero is not a person, the emblem
Of him, even if Xenophon, seems
To stand taller than a person stands, has
A wider brow, large and less human
Eyes and bruted ears: the man-like body
Of a primitive.”
—Wallace Stevens (1879–1955)
“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)
