Famous quotes containing the words operating and/or systems:

    “I think there are innumerable gods. What we on earth call God is a little tribal God who has made an awful mess. Certainly forces operating through human consciousness control events.”
    —William Burroughs (b. 1914)

    “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)
