ABSTRACT
It has been a common assumption in the history of depth psychology that Carl Jung came to depth psychology as an original supporter of Sigmund Freud's model but that he then broke away from Freud over differences in theory, going on to develop his own psychological ideas. The facts are, however, rather different. Before he had even heard of Freud, indeed before Freud had even written the book Interpretation of Dreams which would later arouse Jung's interest, Jung was very much occupied with the scientific issues of the day concerning psychology and did in fact have his own model of the mind. From 1896 to 1899, as a young medical student, Jung gave a series of lectures at his university fraternity that contain the essential elements of many of his later ideas. The Zofingia lectures contain not only Jung's standpoint regarding the vitalist–materialist controversy of the day, but also offer indications on his views on consciousness, the unconscious, and the ego.
