What we have learned by applying psychoanalysis to the arts can be transferred back to psychoanalysis. Freud's discoveries transcended his own natural science heritage and thus paralleled those of Einstein and the relativity physicists who learned that "we cannot separate the world we know from the way we know the world." As part of the observed world, the observer too must be understood. Freud revolutionized our self-understanding and with it our view of art. He made it possible to talk not only about the individuality of the artist, but also about the individuality of each of us as we experience and enjoy art. Art becomes a co-creation of the creators and observers in a partnership of communication and enlightenment.
