Carl G. Jung's theory of personality as developed in his prolific writings and as applied to a wide range of human phenomena stands as one of the most remarkable achievements in modern thought. The originality and audacity of his thinking have few parallels in recent scientific history, and his researches in comparative mythology, religion, and the occult sciences have inspired many of the creative scholars of our time. In making this selection from the vast body of Jung's writing, Joseph Campbell has had two distinct aims: first, to acquaint the reader with the elementary terms and themes of analytical psychology; and second, to provide an introduction to THE COLLECTED WORKS so that the reader will have an over-all sense of their scope and direction. Not only does this approach make possible a substantial understanding of Jung's psychology, but it also enables the reader to follow Systematically the entire development of his thought and ideas from the early experimental studies of complexes and dreams to the larger, cultural-historical, mythological orientations.
