We are accustomed to speak of ideas as reproduced, as passed from mind to mind, as similar or dissimilar to one another, and, in short, as if they were substantial things; nor can any reasonable objection be raised to such expressions. But taking the word "idea" in the sense of an event in an individual consciousness, it is clear that an idea once past is gone forever, and any supposed recurrence of it is another idea. These two ideas are not present in the same state of consciousness, and therefore cannot possibly be compared.

The definition of definition is at bottom just what the maxim of pragmatism expresses.

Time with its continuity logically involves some other kind of continuity than its own. Time, as the universal form of change, cannot exist unless there is something to undergo change, and to undergo a change continuous in time, there must be a continuity of changeable qualities.

Three conceptions are perpetually turning up at every point in every theory of logic, and in the most rounded systems they occur in connection with one another. They are conceptions so very broad and consequently indefinite that they are hard to seize and may be easily overlooked. I call them the conceptions of First, Second, Third. First is the conception of being or existing independent of anything else. Second is the conception of being relative to, the conception of reaction with, something else. Third is the conception of mediation, whereby a first and second are brought into relation.

The consciousness of a general idea has a certain "unity of the ego" in it, which is identical when it passes from one mind to another. It is, therefore, quite analogous to a person, and indeed, a person is only a particular kind of general idea.

In fact, this infinitesimally spread-out consciousness is a direct feeling of its contents as spread out. In an infinitesimal interval we directly perceive the temporal sequence of its beginning, middle, and end... Now upon this interval follows another, whose beginning is the middle of the former, and whose middle is the end of the former. Here we have an immediate perception of the temporal sequence of its beginning, middle and end, or say, of the second, third, and fourth instants.

A pair of statements may be taken conjunctively or disjunctively; for example, "It lightens and it thunders," is conjunctive, "It lightens or it thunders" is disjunctive. Each such individual act of connecting a pair of statements is a new monad for the mathematician.

What distinct meaning can attach to saying that an idea in the past in any way affects an idea in the future, from which it is completely detached?

By an object, I mean anything that we can think, i.e. anything we can talk about.

The development of the human mind has practically extinguished all feelings, except a few sporadic kinds, like sound, colors, smells, warmth, etc., which now appear to be disconnected and separate.

The origin of things, considered not as leading to anything, but in itself, contains the idea of First, the end of things that of Second, the process mediating between them that of Third. A philosophy which emphasises the idea of the One, is generally a dualistic philosophy in which the conception of Second receives exaggerated attention: for this One (though of course involving the idea of First) is always the other of a manifold which is not one. The idea of the Many, because variety is arbitrariness and arbitrariness is repudiation of any Secondness, has for its principal component the conception of First. In psychology Feeling is First, Sense of reaction Second, General conception Third, or mediation. In biology, the idea of arbitrary sporting is First, heredity is Second, the process whereby the accidental characters become fixed is Third. Chance is First, Law is Second, the tendency to take habits is Third. Mind is First, Matter is Second, Evolution is Third.

It is the man of science, eager to have his every opinion regenerated, his every idea rationalized, by drinking at the fountain of fact, and devoting all the energies of his life to the cult of truth, not as he understands it, but as he does not yet understand it, that ought properly to be called a philosopher. To an earlier age knowledge was power - merely that and nothing more; to us it is life and the summum bonum. Emancipation from the bonds of self, of one's own prepossessions, importunately sought at the hands of that rational power before which all must ultimately bow, - this is the characteristic that distinguishes all the great figures of nineteenth-century science from those of former periods.

From these two immediate perceptions, we gain a mediate, or inferential perception of the relation of all four instants. This mediate perception is objectively, or as to the object being represented, spread over the four instants; but subjectively, or as itself the subject of duration, it is completely embraced in the second moment. (The reader will observe that I use the word instant to mean a point in time, and moment to mean an infinitesimal duration.

To suppose universal laws of nature capable of being apprehended by the mind and yet having no reason for their special forms, but standing inexplicable and irrational, is hardly a justifiable position. Uniformities are precisely the sort of facts that need to be accounted for. That a pitched coin should sometimes turn up heads and sometimes tails calls for no particular explanation; but if it shows heads every time, we wish to know how this result has been brought about. Law is par excellence the thing that wants a reason.

We have here a question of difficulty, analogous to the question of nominalism and realism.

The entire universe is perfused with signs, if it is not composed exclusively of signs.

In the case of colors, there is a tridimensional spread of feelings. Originally all feelings may have been connected in the same way, and the presumption is that the number of dimensions was endless. For development essentially involves a limitation of possibilities. But given a number of dimensions of feeling, all possible varieties are obtainable by varying the intensities of the different elements.

May some future student go over this ground again, and have the leisure to give his results to the world.

Just as man as a social being, cannot in the long run exist without a tie to the community, so the individual will never find the real justification for his existence, and his own spiritual and moral autonomy, anywhere except in an extramundane principle capable of relativizing the overpowering influence of external factors.

Among all my patients in the second half of life-that is to say, over thirty-five-there has not been one whose problem in the last resort was not that of finding a religious outlook on life. It is safe to say that every one of them fell ill because he had lost what the living religions of every age have given their followers, and none of them has been really healed who did not regain his religious outlook.

Sometimes I had an overwhelming urge to speak, not about that, but only to hint that there were some curious things about me which no one knew of. I wanted to find out whether other people had undergone similar experiences. I never succeeded in discovering so much as a trace of them in others. As a result, I had the feeling that I was either outlawed or elect, accursed or blessed.

I am an orphan, alone; nevertheless I am found everywhere. I am one, but opposed to myself. I am youth and old man at one and the same time. I have known neither father nor mother, because I have had to be fetched out of the deep like a fish, or fell like a white stone from heaven. In woods and mountains I roam, but I am hidden in the innermost soul of man. I am mortal for everyone, yet I am not touched by the cycle of aeons.

We Shall Naturally look round in vain the macrophysical world for acausal events, for the simple reason that we cannot imagine events that are connected non-causally and are capable of a non-causal explanation. But that does not mean that such events do not exist... The so-called "scientific view of the world" based on this can hardly be anything more than a psychologically biased partial view which misses out all those by no means unimportant aspects that cannot be grasped statistically.

All ages before ours believed in gods in some form or other. Only an unparalleled impoverishment in symbolism could enable us to rediscover the gods as psychic factors, which is to say, as archetypes of the unconscious. No doubt this discovery is hardly credible as yet.

Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no mean of proving immortality), why should we bother with evidence?

It is astounding that man, the instigator, inventor and vehicle of all these developments, the originator of all judgements and decisions and the planner of the future, must make himself such a quantité negligeable.

Our studies of sexual life, originating in Vienna and in England, are matched or surpassed by Hindu teachings on this subject... Psychoanalysis itself and the lines of thought to which it gives rise-surely a distinctly Western development-are only a beginner's attempt compared to what is an immemorial art in the East.

My interests drew me in different directions. On the one hand I was powerfully attracted by science, with its truths based on facts; on the other hand I was fascinated by everything to do with comparative religion. [...] In science I missed the factor of meaning; and in religion, that of empiricism.

Every archetype is capable of endless development and differentiation. It is therefore possible for it to be more developed or less. In an outward form of religion where all the emphasis is on the outward figure (hence where we are dealing with a more or less complete projection) the archetype is identical with externalized ideas but remains unconscious as a psychic factor. When an unconscious content is replaced by a projected image to that extent, it is cut off from all participation in an influence on the conscious mind. Hence it largely forfeits its own life, because prevented from exerting the formative influence on consciousness natural to it; what is more, it remains in its original form - unchanged, for nothing changes in the unconscious.

Primitive superstition lies just below the surface of even the most tough-minded individuals, and it is precisely those who most fight against it who are the first to succumb to its suggestive effects.

If there is anything that we wish to change in the child, we should first examine it and see whether it is not something that could better be changed in ourselves.

Every step closer to my soul excites the scornful laughter of my devils, those cowardly ear-whisperers and poison-mixers. It was easy for them to laugh, since I had to do strange things.

Without consciousness there would, practically speaking, be no world, for the world exists as such only in so far as it is consciously reflected and considered by a psyche. Consciousness is a precondition of being.

But we must not forget that only a very few people are artists in life; that the art of life is the most distinguished and rarest of all the arts. Modern Man in Search of a Soul.

It is only natural that I should constantly have revolved in my mind the question of the relationship of the symbolism of the unconscious to Christianity as well as to other religions. Not only do I leave the door open for the Christian message, but I consider it of central importance for Western man. It needs, however, to be seen in a new light, in accordance with the changes wrought by the contemporary spirit.

The conscious mind allows itself to be trained like a parrot, but the unconscious does not - which is why St. Augustine thanked God for not making him responsible for his dreams.

Naturally, every age thinks that all ages before it were prejudiced, and today we think this more than ever and are just as wrong as all previous ages that thought so. How often have we not seen the truth condemned! It is sad but unfortunately true that man learns nothing from history.

This world is empty to him alone who does not understand how to direct his libido towards objects, and to render them alive and beautiful for himself, for Beauty does not indeed lie in things, but in the feeling that we give to them.

So it is that you come to know what a real God is. ... The God wants my life. He wants to go with me, sit at the table with me, work with me. Above all he wants to be ever-present.

You can take away a man's gods, but only to give him others in return.

A more or less superficial layer of the unconscious is undoubtedly personal. I call it the "personal unconscious". But this personal layer rests upon a deeper layer, which does not derive from personal experience and is not a personal acquisition but is inborn. This deeper layer I call the "collective unconscious". I have chosen the term "collective" because this part of the unconscious is not individual but universal; in contrast to the personal psyche, it has contents and modes of behaviour that are more or less the same everywhere and in all individuals.

As far as we can discern, the sole purpose of human existence is to kindle a light in the darkness of mere being.

People will do anything, no matter how absurd, in order to avoid facing their own souls. They will practice Indian yoga and all its exercises, observe a strict regimen of diet, learn the literature of the whole world-all because they cannot get on with themselves and have not the slightest faith that anything useful could ever come out of their own souls. Thus the soul has gradually been turned into a Nazareth from which nothing good can come.

Aging people should know that their lives are not mounting and unfolding but that an inexorable inner process forces the contraction of life. For a young person it is almost a sin - and certainly a danger - to be too much occupied with himself; but for the aging person it is a duty and a necessity to give serious attention to himself.

It is sometimes difficult to avoid the impression that there is a sort of foreknowledge of the coming series of events.

Where love rules, there is no will to power; and where power predominates, there love is lacking. The one is the shadow of the other.

My soul, my soul, where are you? Do you hear me? I speak, I call you-are you there? I have returned, here I am again. I have shaken the dust of all the lands from my feet, and I have come to you again, I am with you. After long years of long wandering, I have come to you anew. Shall I tell you everything I have seen, experienced, and drunk in? Or do you not want to hear about all the noise of life and the world? But one thing you must know, the one thing I have learned is that one must live this life. This life is the way, the long sought-after way to the unfathomable, which we call "divine". There is no other way. All other ways are false paths.

The seat of faith, however, is not consciousness but spontaneous religious experience, which brings the individual's faith into immediate relation with God. Here we must ask: Have I any religious experience and immediate relation to God, and hence that certainty which will keep me, as an individual, from dissolving in the crowd?

Why is psychology the youngest of the empirical sciences? Why have we not long since discovered the unconscious and raised up its treasure-house of eternal images? Simply because we had a religious formula for everything psychic - and one that is far more beautiful and comprehensive than immediate experience. Though the Christian view of the world has paled for many people, the symbolic treasure-rooms of the East are still full of marvels that can nourish for a long time to come the passion for show and new clothes. What is more, these images - be they Christian or Buddhist or what you will - are lovely, mysterious, richly intuitive.

For lack of empirical data I have neither knowledge nor understanding of such forms of being, which are commonly called spiritual. ...Nevertheless, we have good reason to suppose that behind this veil there exists the uncomprehended absolute object which affects and influences us-and to suppose it even, or particularly, in the case of psychic phenomena about which no verifiable statements can be made.
