Wholly unprepared, we embark upon the second half of life. Or are there perhaps colleges for forty-year-olds which prepare them for their coming life… - Carl Jung

Thoroughly unprepared, we take the step into the afternoon of life. Worse still, we take this step with the false presupposition that our truths and our ideals will serve us as hitherto. But we cannot live the afternoon of life according to the program of life’s morning, for what was great in the morning will be little at evening and what in the morning was true, at evening will have become a lie.

"what is illusion? By what criterion do we judge something to be an illusion? Does there exist for the psyche anything which we may call "illusion"? What we are pleased to call such may be for the psyche a most important factor of life — something as indispensable as oxygen for the organism — a psychic actuality of prime importance. Presumably the psyche does not trouble itself about our categories of reality, and it would therefore be the better part of wisdom for us to say: everything that acts is actual."

The assumption that the human psyche possesses layers that lie below consciousness is not likely to arouse serious opposition. But... there could just as well be layers lying above consciousness... The conscious mind can only claim a relatively central position and must put up with the fact that the unconscious psyche transcends and as it were surrounds it on all sides. Unconscious contents connect it backward with the physiological states on the one hand and archetypal data on the other. But it is extended forward by intuitions which are conditioned partly by archetypes and partly by subliminal perceptions depending on the relativity of time and space in the unconscious.

The great problems of life — sexuality, of course, among others — are always related to the primordial images of the collective unconscious. These images are really balancing or compensating factors which correspond with the problems life presents in actuality. This is not to be marvelled at, since these images are deposits representing the accumulated experience of thousands of years of struggle for adaptation and existence.
