There lies the gravamen of the book, [Psychological Types] though most readers have not noticed this because they are first of all led into the temptation of classifying everything typologically, which in itself is a pretty sterile undertaking. ~Carl Jung, Letters Vol. I, Pages 186-187

Well, you see, the [psychological] type is nothing static. It changes in the course of life… Carl Jung, C.G. Jung, Speaking, Page 435.

I have never thought of my typology as a characterological method and have never applied it in this sense. ~Carl Jung, Letters Vol. I, Pages 129-130

So it is not the case at all that I begin by classifying my patients into types and then give them the corresponding advice, as a colleague of mine whom God has endowed with a peculiar wit once asserted. ~Carl Jung, Letters Vol. I, Pages 186-187

Whereas the extravert needs the object to bring his type to perfection and to cleanse his feeling, the introvert experiences this as a horrible violation and disrespect of his personality, because he absolutely refuses to be, so to speak, the chemical dry cleaner for the feelings of extraverts. ~Carl Jung, Jung-Schmid Correspondence, Pages 55-62.

I have spoken more than once of the way an intuitive type can neglect reality, and you can, I am sure, supply an equal number of examples of the ways a feeling type can do the same thing. ~Carl Jung, 1925 Seminar, Page 135

Each function type has a special way of viewing feeling, and is likely to find things about it which are untrue for the other types. Thus one of the points with respect to the functions that has been most combated is my contention that feeling is rational. ~Carl Jung, 1925 Seminar, Page 134

Well, you see, the [psychological] type is nothing static. It changes in the course of life… Carl Jung, C.G. Jung, Speaking, Page 435.

As a rule, whenever such a falsification of type takes place . . . the individual becomes neurotic later, and can be cured only by developing the attitude consonant with his nature. ~Carl Jung, CW 6, Para 560.

The classification of individuals [By Type] means nothing at all. It is only the instrumentality, or what I call “practical psychology,” used to explain, for instance, the husband to a wife, or vice versa. ~Carl Jung, Evans Conversations, Page 23.

So, through the study of all sorts of human types, I came to the conclusion that there must be many different ways of viewing the world through these type orientations—at least 16, and you can just as well say 360. ~Carl Jung, Evans Conversations, Page 24.

Even though assignment to a particular type may in certain cases have lifelong validity, in other very frequent cases it is so dependent on so many external and internal factors that the diagnosis is valid only for certain periods of time. ~Carl Jung, Letters Vol. II, Pages 346-348

He thinks the sensation type spends his life with corpses, but once he has taken up this inferior function in himself, he begins to enjoy the object as it really is and for its own sake instead of seeing it through an atmosphere of his projections. ~Carl Jung, 1925 Seminar, Page 90

Certainly seeing the top and the bottom is an introverted attitude, but that is just the place the introvert fills. He has distance between himself and the object and so is sensitive to types—he can separate and discriminate. He does not want too many facts and ideas about. ~Carl Jung, 1925 Seminar, Page 94

The inferior function can only come up at the expense of the superior, so that in the intuitive type the intuitions have to be overcome, so to speak, in order for the transcendent function to be found. ~Carl Jung, 1925 Seminar, Page 27

On the other hand, if the person is a sensation type, then the intuitions are the inferior function, and the transcendent function may be said to be arrived at through intuition. ~Carl Jung, 1925 Seminar, Page 27

Out of these experiences that were partly personal, I wrote a little pamphlet on the psychological types, and afterwards read it as a paper before a congress. There were contained in this several mistakes which I afterwards could rectify. ~Carl Jung, 1925 Seminar, Page 33

I watched the creation of myths going on, and got an insight into the structure of the unconscious, forming thus the concept that plays such a role in the Types. ~Carl Jung, 1925 Seminar, Page 35

The author shows an amazingly sympathetic knowledge of the introvert of the thinking type, and hardly less for the other types. . . . Jung has revealed the inner kingdom of the soul marvelously well and has made the signal discovery of the value of phantasy. His book has a manifold reach and grasp, and many reviews with quite different subject matter could be written about it.” ~Sonu Shamdasani, Introduction 1925 Seminar, Page xi

So in my view an “ideally oriented type” is not an analyzed type at all, but an unanalyzed one, someone, for example, who only has a very good sailing boat, but without a built- in motor, thus a vehicle that does not move for hours when there is no wind. ~Carl Jung, Jung-Schmid Correspondence, Pages 74-86

The extravert (the ideal type) must realize his feeling, the corresponding introvert his thinking. In this process, the extravert notices that his feeling is pregnant with thoughts; the introvert, that his thinking is full of feelings. ~Carl Jung, Han Guisan Schmid, Pages 131-142

His [Freud] general way of living was a genuinely introverted style, whereas Adler, whom I met as a young man, being of my age, gave me the impression of a neurotic introvert, in which case there is always a doubt as to the definite type. ~Carl Jung, Letters Vol. I, Pages 301-302

As you know, Freud himself was neurotic his life-long. I myself analyzed him for a certain very disagreeable symptom which in consequence of the treatment was cured. That gave me the idea that Freud as· well as Adler underwent a change in their personal type. ~Carl Jung, Letters Vol. I, Pages 301-302

Certainly strife and misunderstanding will always be among the props of the tragi-comedy of human existence, but it is none the less undeniable that the advance of civilization has led from the law of the jungle to the establishment of courts of justice and standards of right and wrong which are above the contending parties. It is my conviction that a basis for the settlement of conflicting views would be found in the recognition of different types of attitude — a recognition not only of the existence of such types, but also of the fact that every man is so imprisoned in his type that he is simply incapable of fully understanding another standpoint. Failing a recognition of this exacting demand, a violation of the other standpoint is practically inevitable. ~Carl Jung, CW 6, Para 847

We know that there is no human foresight or wisdom that can prescribe direction to our life, except for small stretches of the way. This is of course true only of the “ordinary” type of life, not of the “heroic” type. The latter kind also exists, though it is much rarer. Here we are certainly not entitled to say that no marked direction can be given to life, or only for short distances. The heroic conduct of life is absolute—that is, it is oriented by fateful decisions, and the decision to go in a certain direction holds, sometimes, to the bitter end. ~Carl Jung, CW 7, Para 72

Experience has convinced me that there are not only different temperaments (“types”), but different stages of psychological development, so that one can well say that there is an essential difference between the psychology of the first and the second half of life. Here again I differ from the others in maintaining that the same psychological criteria are not applicable to the different stages of life. ~Carl Jung, CW 4, Para 762
