The Handbook of Jungian Psychology: Theory, Practice and Applications

by Renos K. Papadopoulos

His close associate Toni Wolff made him aware that beyond extraversion–introversion and thinking–feeling, which so far organised the psyche along strictly rational grounds, there was another axis of orientation altogether that his theory would need take into account, the ‘irrational’ axis of sensation–intuition. (Jung himself seems to have recognised that the difference between his original thinking–feeling axis and Wolff’s sensation–intuition axis was that the first pair of functions are deployed in a rational way to interpret experience, whereas the latter merely apprehend what is already given to us by the outer or inner world, and hence do not use any optional process of cognition or evaluation: see Marshall 1968.)
