A layman will no doubt find it hard to understand how pathological disorders of the body and mind can be eliminated by 'mere' words. He will feel that he is being asked to believe in magic. And he will not be so very wrong, for the words which we use in our everyday speech are nothing other than watered-down magic. But we shall have to follow a roundabout path in order to explain how science sets about restoring to words a part at least of their former magical power.

Analogies, it is true, decide nothing but they can make one feel more at home.

Being in love with the one parent and hating the other are among the essential constituents of the stock of psychical impulses which is formed at that time and which is of such importance in determining the symptoms of the later neurosis... This discovery is confirmed by a legend that has come down to us from classical antiquity: a legend whose profound and universal power to move can only be understood if the hypothesis I have put forward in regard to the psychology of children has an equally universal validity. What I have in mind is the legend of King Oedipus and Sophocles' drama which bears his name.

For I am actually not at all a man of science, not an observer, nor an experimenter, not a thinker. I am by temperament nothing but a conquistador—an adventurer... with all the curiosity, daring, and tenacity characteristic of a man of this sort.

I cannot face with comfort the idea of life without work; work and the free play of the imagination are for me the same thing, I take no pleasure in anything else.

I no longer count as one of my merits that I always tell the truth as much as possible; it has become my metier.

In human beings pure masculinity or femininity is not to be found either in a psychological or biological sense.

In matters of sexuality we are at present, every one of us, ill or well, nothing but hypocrites.

In the course of centuries the naïve self-love of men has had to submit to two major blows at the hands of science. The first was when they learnt that our earth was not the centre of the universe but only a tiny fragment of a cosmic system of scarcely imaginable vastness... the second blow fell when biological research destroyed man's supposedly privileged place in creation and proved his descent from the animal kingdom and his ineradicable animal nature… But human megalomania will have suffered its third and most wounding blow from the psychological research of the present time which seeks to prove to the ego that it is not even master in its own house, but must content itself with scanty information of what is going on unconsciously in its mind.

In this House on July 24, 1895 the Secret of Dreams was revealed to Dr. Sigmund Freud.
Plaque was placed on 6 May 1977 at Bellevue (a house on the slopes of the Wienerwald) where the Freud family spent their summers.

In view of the kind of matter we work with, it will never be possible to avoid little laboratory explosions.

It is unreasonable to expect science to produce a system of ethics—ethics are a kind of highway code for traffic among mankind—and the fact that in physics atoms which were yesterday assumed to be square are now assumed to be round is exploited with unjustified tendentiousness by all who are hungry for faith; so long as physics extends our dominion over nature, these changes ought to be a matter of complete indifference to you.

Neurosis is the result of a conflict between the ego and its id, whereas psychosis is the analogous outcome of a similar disturbance in the relation between the ego and the external world.

No one who has seen a baby sinking back satiated from the breast and falling asleep with flushed cheeks and a blissful smile can escape the reflection that this picture persists as a prototype of the expression of sexual satisfaction in later life.

No, our science is no illusion. But an illusion it would be to suppose that what science cannot give us we can get elsewhere.

Psychiatry is the art of teaching people how to stand on their own feet while reclining on couches.

Religion is comparable to a childhood neurosis.

Sexuality is the key to the problem of the psychoneuroses and of the neuroses in general. No one who disdains the key will ever be able to unlock the door.

Smoking is indispensable if one has nothing to kiss.

Sometimes a cigar is just a cigar.

The ego is not master in its own house.

The excremental is all too intimately and inseparably bound up with the sexual; the position of the genitals—inter urinas et faeces—remains the decisive and unchangeable factor. One might say here, varying a well-known saying of the great Napoleon: 'Anatomy is destiny'.

The fateful question for the human species seems to me to be whether and to what extent their cultural development will succeed in mastering the disturbance of their communal life by the human instinct of aggression and self-destruction … One thing only do I know for certain and that is that man's judgements of value follow directly from his wihes for happiness—that, accordingly, they are an attempt to support his illusions with arguments. (1930)

The great question that has never been answered and which I have not been able to answer, despite my thirty years of research into the feminine soul, is 'What does a woman want?'
Freud once said to Marie Bonaparte.

The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind.

The price we pay for our advance in civilization is a loss of happiness through the heightening of the sense of guilt.

The reproaches against science for not having yet solved the problems of the universe are exaggerated in an "unjust and malicious manner; it has truly not had time enough yet for these great achievements. Science is very young—-a human activity which developed late.

The unconscious is the true psychical reality; in its innermost nature it is as much unknown to us as the reality of the external world, and it is as incompletely presented by the data of consciousness as is the external world by the communications of our sense organs.

We know less about the sexual life of little girls than of boys. But we need not feel ashamed of this distinction; after all, the sexual life of adult women is a 'dark continent' for psychology.

We may lay it down that a happy person never phantasises, only an unsatisfied one... The motive forces of phantasies are unsatisfied wishes, and every single phantasy is the fulfilment of a wish, a correction of unsatisfying reality. These motivating wishes vary according to the sex, character and circumstances of the person who is having the phantasy; but they fall naturally into two main groups. They are either ambitious wishes, which serve to elevate the subject's personality; or they are erotic ones. It was shocking when Nietzsche said this, but today it is commonplace; our historical position—and no end to it is in sight—is that of having to philosophise without 'foundations'.

When someone abuses me I can defend myself, but against praise I am defenceless.

Wit is the best safety valve modern man has evolved; the more civilization, the more repression, the more the need there is for wit.

You may take it as an instance of male injustice if I assert that envy and jealousy play an even greater part in the mental life of women than of men. It is not that I think these characteristics are absent in men or that I think they have no other roots in women than envy for the penis; but I am inclined to attribute their greater amount in women to this latter influence.

[The child] takes his play very seriously and he expends large amounts of emotion on it. The opposite of play is not what is serious but what is real.

Freud becomes one of the dramatis personae, in fact, as discoverer of the great and beautiful modern myth of psychoanalysis. By myth, I mean a poetic, dramatic expression of a hidden truth; and in placing this emphasis, I do not intend to put into question the scientific validity of psychoanalysis.

[Freud's] great strength, though sometimes also his weakness, was the quite extraordinary respect he had for the singular fact... When he got hold of a simple but significant fact he would feel, and know, that it was an example of something general or universal, and the idea of collecting statistics on the matter was quite alien to him.

I can still recall vividly how Freud said to me, 'My dear Jung, promise me never to abandon the sexual theory. That is the most essential thing of all. You see, we must make a dogma of it, an unshakable bulwark' ... In some astonishment I asked him, 'A bulwark-against what?' To which he replied, 'Against the black tide of mud'—and here he hesitated for a moment, then added—'of occultism'.

C'est à vous d'être lacaniens, si vous voulez. Moi, je suis freudien.
You can be Lacanians, if you want. As for me, I'm a Freudian.

Freud expressed the opinion—not quite in earnest, though, it seeemed to me—that philosophy was the most decent form of sublimation of repressed sexuality, nothing more. In response I put the question, 'What then is science, particularly psychoanalytic psychology?' Whereup on he, visible a bit surprised, answered evasively: 'At least psychology has a social purpose.'

I believe—and human psychologists, particularly psychoanalysts should test this—that present-day civilized man suffers from insufficient discharge of his aggressive drive. It is more than probable that the evil effects of the human aggressive drives, explained by Sigmund Freud as the results of a special death wish, simply derive from the fact that in prehistoric times intra-specific selection bred into man a measure of aggression drive for which in the social order today he finds no adequate outlet.
