"...Serious and accurate considerations of psychoanalysis led to substantial contributions in at least three separate areas of concrete work...The third contribution is largely the contribution of Jung. The difference between his influence and Freud's arose chiefly from Jung's explanation of the term "libido." Freud had used this term to designate sexual energy; Jung preferred to expand its definition. Linked with this fundamental difference of interpretation was the much greater emphasis Jung put upon what he called the "collective unconscious," which has been described as "the precipitate of humanity's typical forms of reaction since the earliest beginnings." The role of the artist became extremely important for Jung; he was considered a form of priest of the "collective unconscious" because he relates the conscious life of his fellows to its archetypes in the unconscious. This view of the unconscious and its availability to art and literature had no small influence upon 20th-century writers and artists. It was one of several germinal theories which stimulated a great critical interest in myth and mythology... Jung's influence served in a way to counteract Freud's rather narrow view of the artist and the tendency of his followers to analyze art in terms of the artist's physic nature. Jung was in a much larger sense concerned with the art of creation and with its significance as a restatement and reshaping of recurrent mythical themes."
