Famous quotes containing the word criteria:

    We should have learnt by now that laws and court decisions can only point the way. They can establish criteria of right and wrong. And they can provide a basis for rooting out the evils of bigotry and racism. But they cannot wipe away centuries of oppression and injustice—however much we might desire it.
    Hubert H. Humphrey (1911–1978)

    The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
    Always yield to the Hands-On Imperative!
    All information should be free.
    Mistrust authority—promote decentralization.
    Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
    You can create art and beauty on a computer.
    Computers can change your life for the better.
    Steven Levy, U.S. writer. Hackers, ch. 2, “The Hacker Ethic,” pp. 27-33, Anchor Press, Doubleday (1984)

    There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.
    —H.L.A. (Herbert Lionel Adolphus)
