1. Thinking
When describing extraverted thinking, I gave a brief characterization of introverted thinking, to which at this stage I must make further reference. Introverted thinking is primarily orientated by the subjective factor. At the least, this subjective factor is represented by a subjective feeling of direction, which, in the last resort, determines judgment. Occasionally, it is a more or less finished image, which to some extent, serves as a standard. This thinking may be conceived either with concrete or with abstract factors, but always at the decisive points it is orientated by subjective data. Hence, it does not lead from concrete experience back again into objective things, but always to the subjective content, External facts are not the aim and origin of this thinking, although the introvert would often like to make it so appear. It begins in the subject, and returns to the subject, although it may [p. 481] undertake the widest flights into the territory of the real and the actual. Hence, in the statement of new facts, its chief value is indirect, because new views rather than the perception of new facts are its main concern. It formulates questions and creates theories; it opens up prospects and yields insight, but in the presence of facts it exhibits a reserved demeanour. As illustrative examples they have their value, but they must not prevail. Facts are collected as evidence or examples for a theory, but never for their own sake. Should this latter ever occur, it is done only as a compliment to the extraverted style. For this kind of thinking facts are of secondary importance; what, apparently, is of absolutely paramount importance is the development and presentation of the subjective idea, that primordial symbolical image standing more or less darkly before the inner vision. Its aim, therefore, is never concerned with an intellectual reconstruction of concrete actuality, but with the shaping of that dim image into a resplendent idea. Its desire is to reach reality; its goal is to see how external facts fit into, and fulfil, the framework of the idea; its actual creative power is proved by the fact that this thinking can also create that idea which, though not present in the external facts, is yet the most suitable, abstract expression of them. Its task is accomplished when the idea it has fashioned seems to emerge so inevitably from the external facts that they actually prove its validity.
But just as little as it is given to extraverted thinking to wrest a really sound inductive idea from concrete facts or ever to create new ones, does it lie in the power of introverted thinking to translate its original image into an idea adequately adapted to the facts. For, as in the former case the purely empirical heaping together of facts paralyses thought and smothers their meaning, so in the latter case introverted thinking shows a dangerous tendency [p. 482] to coerce facts into the shape of its image, or by ignoring them altogether, to unfold its phantasy image in freedom. In such a case, it will be impossible for the presented idea to deny its origin from the dim archaic image. There will cling to it a certain mythological character that we are prone to interpret as 'originality', or in more pronounced cases' as mere whimsicality; since its archaic character is not transparent as such to specialists unfamiliar with mythological motives. The subjective force of conviction inherent in such an idea is usually very great; its power too is the more convincing, the less it is influenced by contact with outer facts. Although to the man who advocates the idea, it may well seem that his scanty store of facts were the actual ground and source of the truth and validity of his idea, yet such is not the case, for the idea derives its convincing power from its unconscious archetype, which, as such, has universal validity and everlasting truth. Its truth, however, is so universal and symbolic, that it must first enter into the recognized and recognizable knowledge of the time, before it can become a practical truth of any real value to life. What sort of a causality would it be, for instance, that never became perceptible in practical causes and practical results?
This thinking easily loses itself in the immense truth of the subjective factor. It creates theories for the sake of theories, apparently with a view to real or at least possible facts, yet always with a distinct tendency to go over from the world of ideas into mere imagery. Accordingly many intuitions of possibilities appear on the scene, none of which however achieve any reality, until finally images are produced which no longer express anything externally real, being 'merely' symbols of the simply unknowable. It is now merely a mystical thinking and quite as unfruitful as that empirical thinking whose sole operation is within the framework of objective facts. [p. 483]
Whereas the latter sinks to the level of a mere presentation of facts, the former evaporates into a representation of the unknowable, which is even beyond everything that could be expressed in an image. The presentation of facts has a certain incontestable truth, because the subjective factor is excluded and the facts speak for themselves. Similarly, the representing of the unknowable has also an immediate, subjective, and convincing power, because it is demonstrable from its own existence. The former says 'Est, ergo est' ('It is ; therefore it is') ; while the latter says 'Cogito, ergo cogito' (' I think ; therefore I think'). In the last analysis, introverted thinking arrives at the evidence of its own subjective being, while extraverted thinking is driven to the evidence of its complete identity with the objective fact. For, while the extravert really denies himself in his complete dispersion among objects, the introvert, by ridding himself of each and every content, has to content himself with his mere existence. In both cases the further development of life is crowded out of the domain of thought into the region of other psychic functions which had hitherto existed in relative unconsciousness. The extraordinary impoverishment of introverted thinking in relation to objective facts finds compensation in an abundance of unconscious facts. Whenever consciousness, wedded to the function of thought, confines itself within the smallest and emptiest circle possible -- though seeming to contain the plenitude of divinity -- unconscious phantasy becomes proportionately enriched by a multitude of archaically formed facts, a veritable pandemonium of magical and irrational factors, wearing the particular aspect that accords with the nature of that function which shall next relieve the thought-function as the representative of life. If this should be the intuitive function, the 'other side' will be viewed with the eyes of a Kubin or a Meyrink. If it is the feeling-function, [p. 484] there arise quite unheard of and fantastic feeling-relations, coupled with feeling-judgments of a quite contradictory and unintelligible character. If the sensation-function, then the senses discover some new and never-before-experienced possibility, both within and without the body. A closer investigation of such changes can easily demonstrate the reappearance of primitive psychology with all its characteristic features. Naturally, the thing experienced is not merely primitive but also symbolic; in fact, the older and more primeval it appears, the more does it represent the future truth: since everything ancient in our unconscious means the coming possibility.
Under ordinary circumstances, not even the transition to the 'other side' succeeds -- still less the redeeming journey through the unconscious. The passage across is chiefly prevented by conscious resistance to any subjection of the ego to the unconscious reality and to the determining reality of the unconscious object. The condition is a dissociation-in other words, a neurosis having the character of an inner wastage with increasing brain-exhaustion -- a psychoasthenia, in fact.
3. Feeling
Introverted feeling is determined principally by the subjective factor. This means that the feeling-judgment differs quite as essentially from extraverted feeling as does the introversion of thinking from extraversion. It is unquestionably difficult to give an intellectual presentation of the introverted feeling process, or even an approximate [p. 490] description of it, although the peculiar character of this kind of feeling simply stands out as soon as one becomes aware of it at all. Since it is primarily controlled by subjective preconditions, and is only secondarily concerned with the object, this feeling appears much less upon the surface and is, as a rule, misunderstood. It is a feeling which apparently depreciates the object; hence it usually becomes noticeable in its negative manifestations. The existence of a positive feeling can be inferred only indirectly, as it were. Its aim is not so much to accommodate to the objective fact as to stand above it, since its whole unconscious effort is to give reality to the underlying images. It is, as it were, continually seeking an image which has no existence in reality, but of which it has had a sort of previous vision. From objects that can never fit in with its aim it seems to glide unheedingly away. It strives after an inner intensity, to which at the most, objects contribute only an accessory stimulus. The depths of this feeling can only be divined -- they can never be clearly comprehended. It makes men silent and difficult of access; with the sensitiveness of the mimosa, it shrinks from the brutality of the object, in order to expand into the depths of the subject. It puts forward negative feeling-judgments or assumes an air of profound indifference, as a measure of self-defence.
Primordial images are, of course, just as much idea as feeling. Thus, basic ideas such as God, freedom, immortality are just as much feeling-values as they are significant as ideas. Everything, therefore, that has been said of the introverted thinking refers equally to introverted feeling, only here everything is felt while there it was thought. But the fact that thoughts can generally be expressed more intelligibly than feelings demands a more than ordinary descriptive or artistic capacity before the real wealth of this feeling can be even approximately [p. 491] presented or communicated to the outer world. Whereas subjective thinking, on account of its unrelatedness, finds great difficulty in arousing an adequate understanding, the same, though in perhaps even higher degree, holds good for subjective feeling. In order to communicate with others it has to find an external form which is not only fitted to absorb the subjective feeling in a satisfying expression, but which must also convey it to one's fellowman in such a way that a parallel process takes place in him. Thanks to the relatively great internal (as well as external) similarity of the human being, this effect can actually be achieved, although a form acceptable to feeling is extremely difficult to find, so long as it is still mainly orientated by the fathomless store of primordial images. But, when it becomes falsified by an egocentric attitude, it at once grows unsympathetic, since then its major concern is still with the ego. Such a case never fails to create an impression of sentimental self-love, with its constant effort to arouse interest and even morbid self-admiration just as the subjectified consciousness of the introverted thinker, striving after an abstraction of abstractions, only attains a supreme intensity of a thought-process in itself quite empty, so the intensification of egocentric feeling only leads to a contentless passionateness, which merely feels itself. This is the mystical, ecstatic stage, which prepares the way over into the extraverted functions repressed by feeling, just as introverted thinking is pitted against a primitive feeling, to which objects attach themselves with magical force, so introverted feeling is counterbalanced by a primitive thinking, whose concretism and slavery to facts passes all bounds. Continually emancipating itself from the relation to the object, this feeling creates a freedom, both of action and of conscience, that is only answerable to the subject, and that may even renounce all traditional values. But so much the more [p. 492] does unconscious thinking fall a victim to the power of objective facts.
