Famous quotes containing the words operations, integration and/or center:

    It may seem strange that any road through such a wilderness should be passable, even in winter, when the snow is three or four feet deep, but at that season, wherever lumbering operations are actively carried on, teams are continually passing on the single track, and it becomes as smooth almost as a railway.
    Henry David Thoreau (1817–1862)

    Look back, to slavery, to suffrage, to integration and one thing is clear. Fashions in bigotry come and go. The right thing lasts.
    Anna Quindlen (b. 1952)

    Thine age asks ease, and since thy duties be
    To warm the world, that’s done in warming us.
    Shine here to us, and thou art everywhere;
    This bed thy center is, these walls, thy sphere.
    John Donne (1572–1631)
