as the leading promoter of Freud's brand of psychoanalysis. Later in his career Jung's thinking diverged significantly from Freudian psychology in ways that are directly relevant to the concept of the inferior function. Jung viewed human personality from a broad perspective, so his system for understanding individual differences and similarities is complex. Jung saw the human psyche as containing everything necessary to grow, adapt, and heal itself. He believed that people were capable of directing their own personality development and benefiting from both positive and negative life experiences (Quenk 2002). In his studies, Carl Jung divided the psyche into the unconscious and the conscious minds. Freud viewed the unconscious as containing the Id, the Superego and the Ego, whereas Jung developed a different model. He described the unconscious as consisting of two major components: the Personal Unconscious and the Collective Unconscious (Quenk 2002). Jung looked at all behavior including neurotic symptoms as ways of stimulating an individual's growth toward completion. He was interested in personality development as it occurred over the life span and saw it as an ongoing process. Personal Unconscious The Personal Unconscious, as conceived by Jung, encompasses the totality of what Freud recognized as "the unconscious" and corresponds to what most of us intuitively associate with the term "unconscious mind." It contains those elements of our own unique life experience which have been forgotten, ignored, repressed, suppressed or otherwise blocked from consciousness. Some of these elements can be easily recalled into consciousness at will, while others may be more difficult to access or retrieve. In simpler terms, the Personal Unconscious are the thoughts, ideas, emotions, and other mental phenomena acquired and repressed during one's lifetime. The Collective Unconscious Many philosophers have advanced the theory that the human mind is a "blank slate," capable of being molded by our upbringing, which includes social experiences. In working with patients, Carl Jung observed the development of repeated themes in different people's artwork, dreams and fantasies. Yet he noticed that many of these themes had no relation to and could not have originated from any connection to the person's own individual life experiences. Jung concluded that, in addition to our Personal Unconscious, we each possess a deeper aspect of the unconscious. It was in identifying this second unconscious region that Jung's model differentiated itself from Freud's. Naming it the Collective Unconscious, Jung theorized that this region contained psychological elements not developed
