Famous quotes containing the words imperfect and/or information:

    He stood, a soldier, to the last right end,
    A perfect patriot and a noble friend,
    But most a virtuous son.
    All offices were done
    By him, so ample, full, and round
    In weight in measure, number, sound,
    As, though his age imperfect might appear,
    His life was of humanity the sphere.
    Ben Jonson (1572–1637)

    Information networks straddle the world. Nothing remains concealed. But the sheer volume of information dissolves the information. We are unable to take it all in.
    Günther Grass (b. 1927)
