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

    In the greatest confusion there is still an open channel to the soul. It may be difficult to find because by midlife it is overgrown, and some of the wildest thickets that surround it grow out of what we describe as our education. But the channel is always there, and it is our business to keep it open, to have access to the deepest part of ourselves.
    Saul Bellow (b. 1915)

    There are no accidents, only nature throwing her weight around. Even the bomb merely releases energy that nature has put there. Nuclear war would be just a spark in the grandeur of space. Nor can radiation “alter” nature: she will absorb it all. After the bomb, nature will pick up the cards we have spilled, shuffle them, and begin her game again.
    Camille Paglia (b. 1947)

    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)
