Carl Jung: The extraordinary impoverishment of introverted thinking is compensated by a wealth of un- conscious facts.

Similarly, the representation of the irrepresentable has an immediate, subjective power of conviction because it demonstrates its own existence.

The one says "Est, ergo est"; the other says "Cogito, ergo cogito."

Intro verted thinking carried to extremes arrives at the evidence of its own subjective existence, and extraverted thinking at the evidence of its complete identity with the objective fact.

Just as the latter abnegates itself by evaporating into the object, the former empties itself of each and every content and has to be satisfied with merely existing.

In both cases the further development of life is crowded out of the thinking function into the domain of the other psychic functions, which till then had existed in a state of relative unconsciousness.

The extraordinary impoverishment of introverted thinking is compensated by a wealth of unconscious facts.

The more consciousness is impelled by the thinking function to confine itself within the smallest and emptiest circle—which seems, however, to contain all the riches of the gods—the more the unconscious fantasies will be enriched by a multitude of archaic contents, a veritable "pandaemonium" of irrational and magical figures, whose physiognomy will accord with the nature of the function that will supersede the thinking function as the vehicle of life.

If it should be the intuitive function, then the "other side" will be viewed through the eyes of a Kubin or a Meyrink.

If it is the feeling function, then quite unheard-of and fantastic feeling relationships will be formed, coupled with contradictory and unintelligible value judgments.

If it is the sensation function, the senses will nose up something new, and never experienced before, in and outside the body.

Closer examination of these permutations will easily demonstrate a recrudescence of primitive psychology with all its characteristic features.

Naturally, such experiences are not merely primitive, they are also symbolic; in fact, the more primordial and aboriginal they are, the more they represent a future truth.

For everything old in the unconscious hints at something coming. Carl Jung, Psychological Types, Para 630.
