Famous quotes containing the words noise and/or power:

    “It is as real
    as splinters stuck in your ear. The noise we steal
    is half a bell. And outside cars whisk by on the suburban street
    and are there and are true.
    What else is this, this intricate shape of air?
    calling me, calling you.”
    —Anne Sexton (1928–1974)

    “Everyone who has ever built anywhere a “new heaven” first found the power thereto in his own hell.”
    —Friedrich Nietzsche (1844–1900)
