“The autonomy of the collective unconscious expresses itself in the figures of anima and animus. They personify those of its contents which, when withdrawn from projection, can be integrated into consciousness.

To this extent, both figures represent functions which filter the contents of the collective unconscious through to the conscious mind. They appear or behave as such, however, only so long as the tendencies of the conscious and unconscious do not diverge too greatly.

Should any tension arise, these functions, harmless till then, confront the conscious mind in personified form and behave rather like systems split off from the personality, or like part souls. This comparison is inadequate in so far as nothing previously belonging to the ego-personality has split off from it; on the contrary, the two figures represent a disturbing accretion.

The reason for their behaving in this way is that though the contents of anima. and. animus can be integrated they themselves cannot, since they are archetypes. As such they are the foundation stones of the psychic structure, which in its totality exceeds the limits of consciousness and therefore can never become the object of direct cognition.

Though the effects of anima and animus can be made conscious, they themselves are factors transcending consciousness and beyond the reach of perception and volition. Hence they remain autonomous despite the integration of their contents, and for this reason they should be borne constantly in mind.” ~Carl Jung; The Syzygy: Anima and Animus
