"Towards the outside, at any rate, the ego seems to maintain clear and sharp lines of demarcation. There is only one state — admittedly an unusual state, but not one that can be stigmatized as pathological — in which it does not do this. At the height of being in love the boundary between ego and object threatens to melt away. Against all the evidence of his senses, a man who is in love declares that "I" and "you" are one, and is prepared to behave as if it were a fact."
"Man kann sich des Eindrucks nicht erwehren, daß die Menschen gemeinhin mit falschen Maßstäben messen, Macht, Erfolg und Reichtum für sich anstreben und bei anderen bewundern, die wahren Werte des Lebens aber unterschätzen."
"But man's helplessness remains and along with it his longing for his father, and the gods. The gods retain their threefold task: they must exorcise the terrors of nature, they must reconcile men to the cruelty of Fate, particularly as it is shown in death, and they must compensate them for the sufferings and privations which a civilized life in common has imposed on them."
"Religion is a system of wishful illusions together with a disavowal of reality, such as we find nowhere else but in a state of blissful hallucinatory confusion. Religion's eleventh commandment is "Thou shalt not question.""
"In so doing, the idea forces itself upon him that religion is comparable to a childhood neurosis, and he is optimistic enough to suppose that mankind will surmount this neurotic phase, just as so many children grow out of their similar neurosis."
"The true believer is in a high degree protected against the danger of certain neurotic afflictions, by accepting the universal neurosis he is spared the task of forming a personal neurosis."
"Our knowledge of the historical worth of certain religious doctrines increases our respect for them, but does not invalidate our proposal that they should cease to be put forward as the reasons for the precepts of civilization. On the contrary! Those historical residues have helped us to view religious teachings, as it were, as neurotic relics, and we may now argue that the time has probably come, as it does in an analytic treatment, for replacing the effects of repression by the results of the rational operation of the intellect."
"Immorality, no less than morality, has at all times found support in religion."
"Where the questions of religion are concerned people are guilty of every possible kind of insincerity and intellectual misdemeanor."
"Religious doctrines … are all illusions, they do not admit of proof, and no one can be compelled to consider them as true or to believe in them."
"A poor girl may have an illusion that a prince will come and fetch her home. It is possible, some such cases have occurred. That the Messiah will come and found a golden age is much less probable."
"Religious ideas have sprung from the same need as all the other achievements of culture: from the necessity for defending itself against the crushing supremacy of nature."
"Es braucht nicht gesagt zu werden, daß eine Kultur, welche eine so große Zahl von Teilnehmern unbefriedigt läßt und zur Auflehnung treibt, weder Aussicht hat, sich dauernd zu erhalten, noch es verdient."
"The voice of the intellect is a soft one, but it does not rest until it has gained a hearing. Ultimately, after endlessly repeated rebuffs, it succeeds. This is one of the few points in which it may be optimistic about the future of mankind, but in itself it signifies not a little."
"If the truth of religious doctrines is dependent on an inner experience that bears witness to the truth, what is one to make of the many people who do not have that experience?"
"We obtain our concept of the unconscious, therefore, from the theory of repression … We see, however that we have two kinds of unconscious — that which is latent but capable of becoming conscious, and that which is repressed and not capable of becoming conscious in the ordinary way."
"The sexual wishes in regard to the mother become more intense and the father is perceived as an obstacle to the mother; this gives rise to the Oedipus complex."
"The functional importance of the ego is manifested in the fact that normally control over the approaches to motility devolves upon it. Thus in its relation to the id it is like a man on horseback, who has to hold in check the superior strength of the horse; with this difference, that the rider tries to do so with his own strength while the ego uses borrowed forces. The analogy may be carried a little further. Often a rider, if he is not to be parted from his horse, is obliged to guide it where it wants to go; so in the same way the ego is in the habit of transforming the id's will into action as if it were its own."
"The ego represents what we call reason and sanity, in contrast to the id which contains the passions."
"At the dawn of religion, all the knowledge of a particular community fitted into a spiritual framework, based largely on religious values and ideas. The spiritual framework itself had to be within the grasp of the simplest member of the community, even if its parables and images conveyed no more than the vaguest hint as to their underlying values and ideas. But if he himself is to live by these values, the average man has to be convinced that the spiritual framework embraces the entire wisdom of his society. For "believing" does not to him mean "taking for granted," but rather "trusting in the guidance" of accepted values. That is why society is in such danger whenever fresh knowledge threatens to explode the old spiritual forms. The complete separation of knowledge and faith can at best be an emergency measure, afford some temporary relief. In western culture, for instance, we may well reach the point in the not too distant future where the parables and images of the old religions will have lost their persuasive force even for the average person; when that happens, I am afraid that all the old ethics will collapse like a house of cards and that unimaginable horrors will be perpetrated. In brief, I cannot really endorse Planck's philosophy, even if it is logically valid and even though I respect the human attitudes to which it gives rise. Einstein's conception is closer to mine. His God is somehow involved in the immutable laws of nature. Einstein has a feeling for the central order of things. He can detect it in the simplicity of natural laws. We may take it that he felt this simplicity very strongly and directly during his discovery of the theory of relativity. Admittedly, this is a far cry from the contents of religion. I don't believe Einstein is tied to any religious tradition, and I rather think the idea of a personal God is entirely foreign to him. But as far as he is concerned there is no split between science and religion: the central order is part of the subjective as well as the objective realm, and this strikes me as being a far better starting point."
"A colleague who met me strolling rather aimlessly in the beautiful streets of Copenhagen said to me in a friendly manner, “You look very unhappy”; whereupon I answered fiercely, “How can one look happy when he is thinking about the anomalous Zeeman effect?”."
"The setup of the book as far as printing and paper are concerned is splendid."
"God made the bulk; surfaces were invented by the devil."
"When I was young, I thought I was the best formalist of my time. I thought I was a revolutionary. When the big problems would come, I would solve them and write about them. The big problems came and passed by, others solved them and wrote about them. I was a classicist and not a revolutionary."
"I don't mind your thinking slowly; I mind your publishing faster than you think."
"This isn't right. This isn't even wrong."
"The failure of the many attempts to measure terrestrially any effects of the earth’s motion..."
"Es gibt keinen Gott und Dirac ist sein Prophet."
"The best that most of us can hope to achieve in physics is simply to misunderstand at a deeper level."
"This is to show the world that I can paint like Titian. [A big drawing of a rectangle] Only technical details are missing."
"The designation "Jungian Psychology" is actually already unscientific sectarianism. I only acknowledge C. G. Jung's contribution to the general psychology of the unconscious."
"In the new pattern of thought we do not assume any longer the detached observer, occurring in the idealizations of this classical type of theory, but an observer who by his indeterminable effects creates a new situation, theoretically described as a new state of the observed system. In this way every observation is a singling out of a particular factual result, here and now, from the theoretical possibilities, therefore making obvious the discontinuous aspect of physical phenomena. Nevertheless, there remains still in the new kind of theory an objective reality, inasmuch as these theories deny any possibility for the observer to influence the result of a measurement, once the experimental arrangement is chosen. Therefore particular qualities of an individual observer do not enter into the conceptual framework of the theory."
"It is always the older that emanates the new one."
""The fact of the existence of two theories [causal and acausal] that contradict each other in Jung … corresponds psychologically to the vascillation between 3 and 4."
"Both of us [seem] to agree that the future of Jung's ideas is not with [psycho-] therapy... but with a unitarian, holistic concept of nature and the position of man in it."
"Although I have no objection to accepting the existence of relatively constant psychic contents that survive personal ego, it must always be born in mind that we have no way of knowing what these contents are actually like "as such." All we can observe is their effect on other living people, whose spiritual level and whose personal unconscious crucially influence the way these contents actually manifest themselves."
"It seems significant that according to quantum physics the indestructibility of energy on one hand — which expresses its timeless existence — and the appearance of energy in space and time on the other hand correspond to two contradictory (complementary) aspects of reality. In fact, both are always present, but in individual cases the one or the other may be more pronounced."
"What now is the answer to the question as to the bridge between the perception of the senses and the concepts, which is now reduced to the question as to the bridge between the outer perceptions and those inner image-like representations. It seems to me one has to postulate a cosmic order of nature — outside of our arbitrariness— to which the outer material objects are subjected as are the inner images... The organizing and regulating has to be posited beyond the differentiation of physical and psychical... I am all for it to call this "organizing and regulating" "archetypes." It would then be inadmissible to define these as psychic contents. Rather, the above-mentioned inner pictures (dominants of the collective unconscious, see Jung) are the psychic manifestations of the archetypes, but which would have to produce and condition all nature laws belonging to the world of matter. The nature laws of matter would then be the physical manifestation of the archetypes."
"When one analyzes the pre-conscious step to concepts, one always finds ideas which consist of "symbolic images." The first step to thinking is a painted vision of these inner pictures whose origin cannot be reduced only and firstly to the sensual perception but which are produced by an 'instinct to imagining' and which are re-produced by different individuals independently, i.e. collectively... But the archaic image is also the necessary predisposition and the source of a scientific attitude. To a total recognition belong also those images out of which have grown the rational concepts."
"The layman always means, when he says "reality" that he is speaking of something self-evidently known; whereas to me it seems the most important and exceedingly difficult task of our time is to work on the construction of a new idea of reality."
"The purely psychological interpretation only apprehends half of the matter. The other half is the revealing of the archetypal basis of the terms actually applied in modern physics. What the final method of observation must see in the production of "background physics" through the unconscious of modern man is a directing of objective toward a future description of nature that uniformly comprises physis and psyche, a form of description that at the moment we are experiencing only in a prescientific phase. To achieve such a uniform description of nature, it appears to be essential to have recourse to the archetypal background of the scientific terms and concepts."
"Later, however, I came to recognize the objective nature of these dreams or fantasies … Thus it was that I gradually came to acknowledge that such fantasies or dreams are neither meaningless nor purely arbitrary but rather convey a sort of "second meaning" of the terms applied."
"When that amusing "Pauli effect" of the overturned vase occurred, on the occasion of the founding of the Jung Institute, I had the immediate and vivid impression that I should "pour out water inside" (— to use the symbolic language that I have acquired from you). Then when the connection between psychology and physics took up a relatively large part of your talk, it became even more clear to me what I was to do. The outcome of all this is the enclosed essay."
"Already in my original paper I stressed the circumstance that I was unable to give a logical reason for the exclusion principle or to deduce it from more general assumptions. I had always the feeling, and I still have it today, that this is a deficiency."
"I have done a terrible thing, I have postulated a particle that cannot be detected."
"Although Heisenberg and Dirac may have been even more creative than Pauli, no physicist alive was more clever."
"I think you and Uhlenbeck have been very lucky to get your spinning electron published and talked about before Pauli heard of it. It appears that more than a year ago Kronig believed in the spinning electron and worked out something; the first person he showed it to was Pauli. Pauli ridiculed the whole thing so much that the first person became also the last and no one else heard anything of it. Which all goes to show that the infallibility of the Deity does not extend to his self-styled vicar on earth."
"He was very easily hurt and therefore would let down a curtain. He tried to live without admitting reality. And his unworldliness stemmed precisely his belief that that was possible."
"I related to Feynman other anecdotes about physicists. Some of these were Pauli stories. I told him what I had learned from Pauli when I asked him about his opinion of various physicists. Feynman especially enjoyed the following remarks of Pauli. About Oppenheimer, Pauli had said: 'He always acts like the caricature of God in action!' About Hermann Weyl: 'One must first penetrate his façade [literally 'makeup', Schminke in German] in order to understand his thoughts.' About Leon Rosenfeld: 'He is the choirboy of the Pope [Niels Bohr]!' About Freeman Dyson, which I had heard from Telegdi: 'Everyone wants to learn something from me; no one wants to teach me anything. I had hoped Dyson would do it, but he's only a mathematician!' By now, Feynman was becoming quite eager: 'Did you ask Pauli about me?' I said, 'Yes.' 'Well, what did he say?' I replied, 'When I asked Pauli what he thought of you, he was amused, and replied, "Oh, Feynman, that Feynman, he talks like a gangster!"' This story made Feynman's day; nothing could have pleased him more."
"The famous physicist Wolfgang Pauli is said to have remarked that the deepest pleasure in science comes from finding an instantiation, a home, for some deeply felt, deeply held image."
