“I have shown in the diagram] the individual in relation to the world of external objects on the one hand and to the collective unconscious images on the other. Connecting him with the first world, that is, the world of external objects, is the persona, developed by the forces from within and the forces from without in interaction with one another. We may think of the persona as the bark of a conscious personality. As we have indicated elsewhere, it is not wholly our choice what the persona shall be, for we can never control entirely the forces that are to play on our conscious personalities.
The center of this conscious personality is the ego. If we take the layer “back” of this ego, we come to the personal subconscious. This contains our incompatible wishes or fantasies, our childhood influences, repressed sexuality, in a word all those things we refuse to hold in consciousness for one reason or another, or which we lose out of it. In the center is the virtual nucleus or central government, representing the totality of the conscious and unconscious self…We can speak of the conscious ego as the subjective personality, and of the shadow self as the objective personality. This latter, made up of what is part of the collective unconscious in us, carries the things that appear in us as effects. For we do have effects on people
which we can neither predict nor adequately explain.”
