Famous quotes containing the words noise and/or power:

    “Sweet bird, that shunn’st the noise of folly,
    Most musical, most melancholy!”
    —John Milton (1608–1674)

    “Here far from the city we make our roadside stand
    And ask for some city money to feel in hand
    To try if it will not make our being expand,
    And give us the life of the moving-pictures’ promise
    That the party in power is said to be keeping from us.”
    —Robert Frost (1874–1963)
