Two world-renowned psychologists, Marie-Louise von Franz and James Hillman, give detailed accounts of C.G. Jung's personality types. In her essay, "The Inferior Function," Marie-Louise von Franz shows the inferior shadow side of each of the eight kinds of typical functioning, while James Hillman differentiates in his essay, "The Feeling Function," genuine feeling from look-alikes and substitutes. Both essays are a rich source of ideas for study and an enjoyable guide for self-discovery. Full of psychological insights into personal habits, temperaments, and character.
