Famous quotes containing the words additional and/or images:

    “Don’t you think I’ve had enough excitement for one evening, without the additional thrill of a strange man making love to me?”
    —John L. Balderston (1899–1954)

    “The world is for thousands a freak show; the images flicker past and vanish; the impressions remain flat and unconnected in the soul. Thus they are easily led by the opinions of others, are content to let their impressions be shuffled and rearranged and evaluated differently.”
    —Johann Wolfgang Von Goethe (1749–1832)
