The anima and animus are described in Carl Jung's school of analytical psychology as part of his theory of the collective unconscious. Jung described the animus as the unconscious masculine side of a woman, and the anima as the unconscious feminine side of a man, each transcending the personal psyche. Jung's theory states that the anima and animus are the two primary anthropomorphic archetypes of the unconscious mind, as opposed to the theriomorphic and inferior function of the shadow archetypes. He believed they are the abstract symbol sets that formulate the archetype of the Self.
