Famous quotes containing the words noise and/or power:

    “There must be no cessation
    Of motion, or of the noise of motion,
    The renewal of noise
    And manifold continuation....”
    —Wallace Stevens (1879–1955)

    “He
    moves in a wood of desire,

    pale antlers barely stirring
    as he hunts. I cannot tell
    what power is at work, drenched there
    with purpose, knowing nothing.”
    —Thom Gunn (b. 1929)
