[Carl Jung on the “Sympathetic Nervous System” – Anthology]
The shadow is a tight passage, a narrow door, whose painful constriction no one is spared who goes down to the deep well. But one must learn to know oneself in order to know who one is. For what comes after the door is, surprisingly enough, a boundless expanse full of unprecedented uncertainty, with apparently no inside and no outside, no above and no below, no here and no there, no mine and no thine, no good and no bad. It is the world of water, where all life floats in suspension; where the realm of the sympathetic system, the soul of everything living, begins; where I am indivisibly this and that; where I experience the other in myself and the other-than-myself experiences me. ~Carl Jung, CW 9i, Para 45
Just as a man has a body which is no different in principle from that of an animal, so also his psychology has a whole series of lower storeys in which the spectres from humanity’s past epochs still dwell, when the animal souls from the age of Pithecanthropus and the hominids, then the “psyche” of the cold-blooded saurians, and, deepest down of all, the transcendental mystery and paradox of the sympathetic and parasympathetic psychoid systems. ~Carl Jung, CW 14, Para 279
The very primitive animal layers are supposed to be inherited through the sympathetic system, and the relatively later animal layers belonging to the vertebrate series are represented by the cerebrospinal system. ~Carl Jung, 1925 Seminar, Page 140
It [Shadow] is the world of water, where all life floats in suspension; where the realm of the sympathetic system, the soul of everything living, begins; where I am indivisibly this and that; where I experience the other in myself and the other-than-myself experiences me. ~Carl Jung, CW 9i, Para 45
The animus, on the other hand, is the higher soul; after death it rises in the air, where at first it is active for a time and then evaporates in ethereal space, or flows back into the reservoir of life. In living men, the two correspond in a certain degree to the cerebral and sympathetic nervous system. ~Carl Jung, Secret of the Golden Flower, Page 15
Our unconscious is surely located in the body, and you mustn’t think this a contradiction to the statement I usually make, that the collective unconscious is everywhere; for if you could put yourself into your sympathetic system, you would know what sympathy is-you would understand why the nervous system is called sympathetic. ~Carl Jung, Zarathustra Seminar, Pages 749-751.
The unconscious is largely identical with the sympathetic and parasympathetic systems, which are the physiological counterparts of the polarity of unconscious contents. ~Carl Jung, Letters Vol. 1, Page 278.
There are certain disturbances of the unconscious, in the sympathetic system, which produce symptoms exactly like organic disturbances. ~Carl Jung, ETH, Page 177.
When it comes to the rather delicate task of locating the collective unconscious, you must not think of it as being compassed by the brain alone but as including the sympathetic nervous system as well. ~Carl Jung, 1925 Seminar, Page 140
