Famous quotes containing the word power:

    Armies, though always the supporters and tools of absolute power for the time being, are always the destroyers of it too; by frequently changing the hands in which they think proper to lodge it.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
