"Every man carries within him the eternal image of woman, not the image of this or that particular woman, but a definitive feminine image. This image is fundamentally unconscious, an hereditary factor of primordial origin engraved in the living organic system of the man, an imprint or archetype of all ancestral experiences of the female, a deposit as it were, of all the impressions ever made by woman." (CW. 17, 198)
While the anima is the personification of the feminine nature of a man's unconscious, the animus is the unconscious masculine nature of a woman's.
"In its primary 'unconscious' form the animus is a compound of spontaneous, unpremeditated opinions which exercise a powerful influence on a woman's emotional life ... Consequently the animus likes to project itself upon 'intellectuals' and all kinds of 'heroes', including tenors, artists, sporting celebrities." (CW. 16,301)
"The anima and animus should function as a bridge, or a door, leading to images of the collective unconscious."
