The Archetypes and The Collective Unconscious (Collected Works of C.G. Jung Vol.9 Part 1)
Anyone who wants to know the human psyche will learn next to nothing from experimental psychology.
We would do well to abandon from the start any attempt to apply ready-made solutions and warmed-up generalities of which the patient knows just as much as the doctor.
Long experience has taught me not to know anything in advance and not to know better, but to let the unconscious take precedence.
Our instincts have ridden so infinitely many times, unharmed, over the problems that arise [in later] life that we may be sure the transformation processes which make the transition possible have long been prepared in the unconscious and are only waiting to be released. ~Carl Jung, CW 9i, Para 528
