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

    O polished perturbation! golden care!
    That keep’st the ports of slumber open wide
    To many a watchful night.
    William Shakespeare (1564–1616)

    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)

    Surely the fates are forever kind, though Nature’s laws are more immutable than any despot’s, yet to man’s daily life they rarely seem rigid, but permit him to relax with license in summer weather. He is not harshly reminded of the things he may not do.
    Henry David Thoreau (1817–1862)
