Famous quotes containing the words noise and/or power:

    “who chained themselves to subways for the endless ride from Battery
    to holy Bronx on benzedrine until the noise of wheels and children
    brought them down shuddering mouth-wracked and battered bleak of brain and drained of brilliance in the drear light of Zoo,”
    —Allen Ginsberg (b. 1926)

    “What wouldst thou do, old man?
    Think’st thou that duty shall have dread to speak
    When power to flattery bows?”
    —William Shakespeare (1564–1616)
