Famous quotes containing the word earth:

    It is, I think, an indisputable fact that Americans are, as Americans, the most self-conscious people in the world, and the most addicted to the belief that the other nations of the earth are in a conspiracy to under value them.
    Henry James (1843–1916)

    till seven years were gane and past,
    True Thomas on earth was never seen.
    Unknown. Thomas the Rhymer (l. 79–80)

    Let Rome in Tiber melt and the wide arch
    Of the ranged empire fall! Here is my space.
    Kingdoms are clay; our dungy earth alike
    Feeds beast as man. The nobleness of life
    Is to do thus; when such a mutual pair
    And such a twain can do ‘t, in which I bind,
    On pain of punishment, the world to weet
    We stand up peerless.
    William Shakespeare (1564–1616)
