She did so and came through with a long statement.
I was greatly intrigued by the fact that a woman should interfere with me from within. My conclusion was that she must be the "soul," in the primitive sense, and I began to speculate on the reasons why the name "anima" was given to the soul. Why was it thought of as feminine? Later I came to see that this inner feminine £gure plays a typical, or archetypal, role in the unconscious of a man, and I called her the "anima." The corresponding £gure in the unconscious of woman I called the "animus. ".»
