Inferior Function

Inferior Function

The inferior function is the fourth and least-differentiated of the four orienting functions of consciousness — thinking, feeling, sensation, intuition — in carl-jung‘s typology. By structural necessity it remains submerged while its three siblings rise into ego-consciousness; the libido withdrawn from it is what permits the favored function to be sharpened. “It reverts to the archaic stage and becomes incompatible with the conscious, favoured function” (Jung 1921, ¶764). It is conscious “at least in its effects” in the normal personality; in neurosis it sinks wholly into the unconscious.

The doctrine is not pathological but structural. Every specialized consciousness leaves a fourth behind; every adaptation purchases its sharpness at the cost of a backward-running organ that does not vanish but lives at the back of the body, untamed. The inferior function carries the law of compensation: “even after long use it never loses its autonomy and spontaneity… Its role is therefore mostly that of a deus ex machina” (Jung 1959, ¶541). What enters the psyche from outside the ego enters most often through this door.

The fourth is “the door through which all the figures of the unconscious enter” (marie-louise-von-franz 1993). The shadow, the anima and animus, even personifications of the self arrive through it carrying its typological coloring. Approached, it works like an inner breakdown — the dissolution of the ego’s possession by its dominant function and the establishment of what von Franz calls the middle realm, the awareness of being more than any one function the psyche commands.
