Jung’s theory of psychological types is an attempt to make comprehensible the regular differences between individuals. His concepts of introversion and extraversion, thinking, feeling, sensation, and intuition have gained wide currency since their introduction in 1920. However, applying these concepts to practical situations is often confusing. Dr. Beebe’s new model of typology shows how the eight types relate to complexes that can be recognized in dreams and styles of behavior. The model, which permits the types to be recognized more easily and with more precision, is illustrated with examples drawn from clinical work and works of creative imagination.
