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)

    I hate that aesthetic game of the eye and the mind, played by these connoisseurs, these mandarins who “appreciate” beauty. What is beauty, anyway? There’s no such thing. I never “appreciate,” any more than I “like.” I love or I hate.
    Pablo Picasso (1881–1973)

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