Famous quotes containing the words open, game and/or license:

    “GOETHE, raised o’er joy and strife,
    Drew the firm lines of Fate and Life,
    And brought Olympian wisdom down
    To court and mar, to gown and town,
    Stooping, his finger wrote in clay
    The open secret of to-day.”
    —Ralph Waldo Emerson (1803–1882)

    “One of life’s primal situations; the game of hide and seek. Oh, the delicious thrill of hiding while the others come looking for you, the delicious terror of being discovered, but what panic when, after a long search, the others abandon you! You mustn’t hide too well. You mustn’t be too good at the game. The player must never be bigger than the game itself.”
    —Jean Baudrillard (b. 1929)

    “Purchasing power is a license to purchase power.”
    —Raoul Vaneigem (b. 1934)
