The tendency of psychic contents or complexes to take on a distinct personality, separate from the ego.
Every autonomous or even relatively autonomous complex has the peculiarity of appearing as a personality, i.e., of being personified.
This can be observed most readily in the so-called spiritualistic manifestations of automatic writing and the like.
The sentences produced are always personal statements and are propounded in the first person singular, as though behind every utterance there stood an actual personality.
A naïve intelligence at once thinks of spirits.[“Anima and Animus,” CW 7, par. 312.]
The ego may also deliberately personify unconscious contents or the affects that arise from them, using the method of active imagination, in order to facilitate communication between consciousness and the unconscious.
