Famous quotes containing the words burst and/or ray:

    We, the lineal representatives of the successful enactors of one scene of slaughter after another, must, whatever more pacific virtues we may also possess, still carry about with us, ready at any moment to burst into flame, the smoldering and sinister traits of character by means of which they lived through so many massacres, harming others, but themselves unharmed.
    William James (1842–1910)

    It has never been my object to record my dreams, just the determination to realize them.
    —Man Ray (1890–1976)
