Famous quotes containing the words orbit and/or earth:

    The human spirit is itself the most wonderful fairy tale that can possibly be. What a magnificent world lies enclosed within our bosoms! No solar orbit hems it in, the inexhaustible wealth of the total visible creation is outweighed by its riches!
    —E.T.A.W. (Ernst Theodor Amadeus Wilhelm)

    Fit gravefellows you are for Lincoln, Brown
    And Douglass and Toussaint. . . all whose rapt eyes
    Fashioned a new world in this wilderness.
    American earth is richer for your bones;
    Our hearts beat prouder for the blood we inherit.
    Dudley Randall (b. 1914)
