Famous quotes containing the words noise and/or power:

    “I will not by the noise of bloody wars and the dethroning of kings advance you to glory: but by the gentle ways of peace and love.”
    —Thomas Traherne (1636–1674)

    “Oh, London is a man’s town, there’s power in the air;
    And Paris is a woman’s town, with flowers in her hair;
    And it’s sweet to dream in Venice, and it’s great to study Rome;
    But when it comes to living, there is no place like home.”
