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

    Oh! joyous hearts! enfired with holy flame!
    Is speech thus tasseled with praise?
    Will not your inward fire of joy contain:
    That it in open flames doth blaze?
    For in Christ’s coach saints sweetly sing,
    As they to glory ride therein.
    Edward Taylor (1645–1729)

    Lyke as a huntsman after weary chace,
    Seeing the game from him escapt away,
    Sits downe to rest him in some shady place,
    Edmund Spenser (1552?–1599)

    My attitude toward punctuation is that it ought to be as conventional as possible. The game of golf would lose a good deal if croquet mallets and billiard cues were allowed on the putting green. You ought to be able to show that you can do it a good deal better than anyone else with the regular tools before you have a license to bring in your own improvements.
    Ernest Hemingway (1899–1961)
