With the possible exception of "The Symbolic Life," this is my favorite of the books in "The Collected Works" of C. G. Jung. Maybe it's synchronistic that one is CW18 and the other is CW8? In any case, this volume includes Jung's thoughts on many of his breakthrough ideas and concepts and describes his model of the psyche. His model adds a 3rd dimension (the collective unconscious) to Freud's (conscious and subconscious). Though, of course, Jung calls the subconscious the personal unconscious. This 3 dimensional view translates the subconscious into the home of the psychological complexes. Jung applied the mathematical concept of complexes (a complex number has a real or rational part plus an irrational [I'd call it non-rational] part which is a multiple of "i" = the square root of minus one). Jung didn't like what he called neologisms = newly created words; especially when an analogous word was already available. He also considered himself an empirical scientist and did not believe his theories were the last word in psychology.
p. 297 The purpose of research is not to imagine that one possesses the theory which alone is right, but doubting all theories, to approach gradually nearer to the truth.
In this volume, Jung explores the relationships among these three layers of the psyche as related to the real world and our knowledge of it.
p. 171 All knowledge is the result of imposing some kind of order upon the reactions of the psychic system as they flow into our consciousness-an order that reflects the behavior of a metapsychic reality or that which is in itself real.
People project their inner psyche upon the external world-very similar to the Tibetan Buddhist Dzogchen and Mahamudra philosophies in which the real world is empty of an inherent nature (it arises only dependent upon causes) and the reality we perceive is an integrated projection of sentient beings, itself being dependently arising. Of course, Jung did study Eastern philosophies and religions.
p. 207 A poorly developed consciousness, for instance which because of massed projections is inordinately impressed by concrete or apparently concrete things and states, will naturally see in the instinctual drives the source of all reality. It remains blissfully unaware of the spirituality of such a philosophical surmise.
Also, his theory of synchronicity (meaningful coincidences) supports this view of the relationship of psyche to matter. This is a bit reminiscent of the Einstein's view (now part of modern physics) that matter and energy are of the same nature.
p. 215 it is not only possible but fairly probable, even, that psyche and matter are two different aspects of one and the same thing. The synchronicity phenomena point, it seems to me, in this direction, for they show that the nonpsychic can behave like the psychic, and vice versa, without there being any causal connection between them.
However, the danger of identifying, incorrectly, to the world of matter on one hand is matched by the danger of identifying with the collective unconscious' Archetypes on the other.
p. 221 Subjective consciousness must, in order to escape this doom, avoid identification with collective consciousness by recognizing its shadow as well as the existence and the importance of the archetypes. These later are an effective defense against the brute force of collective consciousness and the mass psyche that goes with it.
Rather balance is to be sought in the Individuation process.
p. 223 Psychology actualizes the unconscious urge to consciousness. It is, in fact, the coming to consciousness of the psychic process. And--
p. 225 Conscious wholeness consists in a successful union of ego and self, so that both preserve their intrinsic qualities. If, instead of this union, the ego is overpowered by the self, then the self too does not attain the form it ought to have, but remains fixed on a primitive level and can express itself only through archaic symbols...If the ego is dissolved in identification with the self, it gives rise to a sort of nebulous superman with a puffed-up ego and a deflated self.
p. 226 Individuation does not shut one out from the world, but gathers the world to oneself.
This implies that we withdraw our projections from the world and make the unconscious conscious.
p. 342 Like primitives, we are at first wholly unconscious of our actions, and only discover long afterwards why it was that we acted in a certain way. In the meantime we content ourselves with all sorts of rationalizations of our behavior, all of them equally inadequate.
