ABSTRACT
It has not always been clear to students of Jung's analytical psychology what his famous 'types' are types of. For psychotherapists, an understanding of these different natural cognitive stances can be invaluable in the daily work of supporting the basic strengths of their clients' personalities and of helping a particular consciousness to recognize its inherent limitations. In the next seven years, in conversation with others in the newly formed Zurich School of Analytical Psychology, he began to unpack his typological theory. Jung's theory of psychological types resembles in some ways the eighteenth-century faculty psychology developed by theorists such as Christian Wolff, Franz Josef Gall (1835), and Thomas Reid. There can be no real advance in the understanding of Jung's most subtle and far-reaching contribution to ego psychology, however, until many more analytical psychologists become much more type-literate than they are nowadays.
