Jung - Anima and Animus In the book Man and His Symbols Jung discusses the Anima and Animus extensively.  As I understand it they are the two primary anthropomorphic archetypes of the collective unconscious.  The Anima is expressed as the inner feminine personality in the unconscious of man; the Animus as the inner masculine personality of the unconscious of female

I found it strange that Jung only talks about the Anima in terms of the male psyche, and the Animus in term of the female psyche.

My question is why isn't there an Animus concept in the male psyche or an Anima concept in the female psyche?

Where is the archetype of the male part of the male unconscious and the female part of the female unconscious? Is that just another piece of the psyche the Jung defines as part of the Self?  Where does the Animus live in the male total psyche?
From the way I understand it, everyone, male or female has both masculine and feminine personalities and it is up to the subjects whether they recognise that or not and to what level.  The idea is that in order to become all you can be you need to integrate yourself with your inner opposite sex.

The animus within the woman and the anima within the man are the opposing personalities to their sex and how they are 'supposed' to behave.  An example would be that if a man has a strongly developed anima (fully accepted and integrated into his psyche) the man will be fully open to emotionality.
