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

    Those who guard their mouths preserve their lives; those who open wide their lips come to ruin.
    Bible: Hebrew, Proverbs 13:3.

    He may travel who can subsist on the wild fruits and game of the most cultivated country.
    Henry David Thoreau (1817–1862)

    I go out of my way, but rather by license than carelessness.... It is the inattentive reader
    who loses my subject, not I. Some word about it will always be found off in a corner, which will not fail to be sufficient, though it takes little room.
    Michel de Montaigne (1533–1592)
