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

    It is open to a war resister to judge between the combatants and wish success to the one who has justice on his side. By so judging he is more likely to bring peace between the two than by remaining a mere spectator.
    Mohandas K. Gandhi (1869–1948)

    The most disgusting cad in the world is the man who, on grounds of decorum and morality, avoids the game of love. He is one who puts his own ease and security above the most laudable of philanthropies.
    —H.L. (Henry Lewis)

    All is possible,
    Who so list believe;
    Trust therefore first, and after preve,
    As men wed ladies by license and leave,
    All is possible.
    Sir Thomas Wyatt (1503?–1542)
