The alchemical process focuses on the transmutation of the metals, the creating of one type out of another. When taken not as a guide to strengths, but weaknesses, Jung’s typology can be seen as a means for finding ways to transform a one sided ego complex into a fully faceted marvel, with eight distinct means if functioning in any given situation. Jung felt that most people develop their primary function, sometimes a secondary one, and rarely in his experience a tertiary function. He often made note that the unconscious has it’s way with us through the inferior forth function.
Jungian analyst John Beebe then went on to develop an understanding of the four daemonic functions, which would have the opposite attitude (introversion or extraversion) of the primary four functions. If introverted intuition is a primary function, extroverted intuition would form the fifth potential function to develop.
Gaining in our capacity to operate through the fullness of the ego complex is part of the journey, the conscious part at least, of becoming whole.
