now go into the theoretical ideas which alone have shown themselves useful in making the conception of repression more definite. It is above all necessary that we progress from a purely descriptive meaning of the word “unconscious” to its more systematic meaning; that is, we come to a point where we must call the consciousness or unconsciousness of a psychic process only one of its attributes, an attribute which is, moreover, not necessarily unequivocal. If such a process remained unconscious, then this separation from consciousness is perhaps only an indication of the fate to which it has submitted and not this fate itself. To bring this home to us more vividly, let us assume that every psychological process — with one exception, which I will go into later — first exists in an unconscious state or phase and only goes over from this into a conscious phase, much as a photographic picture is first a negative and then becomes a picture by being printed. But not every negative need become a positive, and just as little is it necessary that every unconscious psychological process should be changed into a conscious one. We find it advantageous to express ourselves as follows: Any particular process belongs in the first place to the psychological system of the unconscious; from this system it can under certain conditions go over into the system of the conscious. The crudest conception of these systems is the one which is most convenient for us, namely, a representation in space. We will compare the system of the unconscious to a large ante-chamber, in which the psychic impulses rub elbows with one another, as separate beings. There opens out of this ante-chamber another, a smaller room, a sort of parlor, which consciousness occupies. But on the threshold between the two rooms there stands a watchman; he passes on the individual psychic impulses, censors them, and will not let them into the parlor if they do not meet with his approval. You see at once that it makes little difference whether the watchman brushes a single impulse away from the threshold, or whether he drives it out again after it has already entered the parlor. It is a question here only of the extent of his watchfulness, and the timeliness of his judgment. Still working with this simile, we proceed to a further elaboration of our nomenclature. The impulses in the ante-chamber of the unconscious cannot be seen by the conscious, which is in the other room; therefore for the time being they must remain unconscious. When they have succeeded in pressing forward to the threshold, and have been sent back by the watchman, then they are unsuitable for consciousness and we call them suppressed. Those impulses, however, which the watchman has permitted to cross the threshold have not necessarily become conscious; for this can happen only if they have been successful in attracting to themselves the glance of the conscious. We therefore justifiably call this second room the system of the fore-conscious. In this way the process of becoming conscious retains its purely descriptive sense. Suppression then, for any individual impulse, consists in not being able to get past the watchman from the system of the unconscious to that of the fore-conscious. The watchman himself is long since known to us; we have met him as the resistance which opposed us when we attempted to release the suppression through analytic treatment.
Now I know you will say that these conceptions are as crude as they are fantastic, and not at all permissible in a scientific discussion. I know they are crude — indeed, we even know that they are incorrect, and if we are not very much mistaken we have a better substitute for them in readiness. Whether they will continue then to appear so fantastic to you I do not know. For the time being, they are useful conceptions, similar to the manikin Ampère who swims in the stream of the electric current. In so far as they are helpful in the understanding of our observation, they are by no means to be despised. I should like to assure you that these crude assumptions go far in approximating the actual situation — the two rooms, the watchman on the threshold between the two, and consciousness at the end of the second room in the role of an onlooker. I should also like to hear you admit that our designations —unconscious, fore-conscious, and conscious are much less likely to arouse prejudice, and are easier to justify than others that have been used or suggested — such as sub-conscious, inter-conscious, between-conscious, etc.
This becomes all the more important to me if you should warn me that this arrangement of the psychic apparatus, such as I have assumed in the explanation of neurotic symptoms, must be generally applicable and must hold for normal functioning as well. In that, of course, you are right. We cannot follow this up at present, but our interest in the psychology of the development of the symptom must be enormously increased if through the study of pathological conditions we have the prospect of finding a key to the normal psychic occurrences which have been so well concealed.
You will probably recognize what it is that supports our assumptions concerning these two systems and their relation to consciousness. The watchman between the unconscious and the fore-conscious is none other than the censor under whose control we found the manifest dream to obtain its form. The residue of the day’s experiences, which we found were the stimuli which set off the dream, are fore-conscious materials which at night, during sleep, had come under the influence of unconscious and suppressed wishes. Borne along by the energy of the wish, these stimuli were able to build the latent dream. Under the control of the unconscious system this material was worked over, went through an elaboration and displacement such as the normal psychic life or, better said, the fore-conscious system, either does not know at all or tolerates only exceptionally. In our eyes the characteristics of each of the two systems were betrayed by this difference in their functioning. The dependent relation between the fore-conscious and the conscious was to us only an indication that it must belong to one of the two systems. The dream is by no means a pathological phenomenon; it may appear in every healthy person under the conditions of sleep. Any assumption as to the structure of the psychic apparatus which covers the development of both the dream and the neurotic symptom has also an undeniable claim to be taken into consideration in any theory of normal psychic life.
So much, then, for suppression. It is, however, only a prerequisite for the evolution of the symptom. We know that the symptom serves as a substitute for a process kept back by suppression. Yet it is no simple matter to bridge this gap between the suppression and the evolution of the substitute. We have first to answer several questions on other aspects of the problem concerning the suppression and its substantiation: What kind of psychological stimuli are at the basis of the suppression; by what forces is it achieved; for what motives? On these matters we have only one insight that we can go by. We learned in the investigation of resistance that it grows out of the forces of the “I,” in other words from obvious and latent traits of character. It must be from the same traits also that suppression derived support; at least they played a part in its development. All further knowledge is still withheld from us.
A second observation, for which I have already prepared, will help us further at this point. By means of analysis we can assign one very general purpose to the neurotic symptom. This is of course nothing new to you. I have already shown it to you in the two cases of neuroses. But, to be sure, what is the significance of two cases! You have the right to demand that it be shown to you innumerable times. But I am unable to do this. Here again your own experience must step in, or your belief, which may in this matter rely upon the unanimous account of all psychoanalysts.
You will remember that in these two cases, whose symptoms we subjected to searching investigation, the analysis introduced us to the most intimate sexual life of these patients. In the first case, moreover, we could identify with unusual clearness the purpose or tendency of the symptoms under investigation. Perhaps in the second case it was slightly covered by another factor — one we will consider later. Now, the same thing that we saw in these two examples we would see in all other cases that we subjected to analysis. Each time, through analysis, we would be introduced to the sexual wishes and experiences of the patient, and every time we would have to conclude that their symptoms served the same purpose. This purpose shows itself to be the satisfaction of sexual wishes; the symptoms serve as a sexual satisfaction for the patient, they are a substitute for such satisfactions as they miss in reality.
Recall the compulsive act of our first patient. The woman longs for her intensely beloved husband, with whom she cannot share her life because of his shortcoming and weaknesses. She feels she must remain true to him, she can give his place to no one else. Her compulsive symptom affords her that for which she pines, ennobles her husband, denies and corrects his weaknesses — above all, his impotence. This symptom is fundamentally a wish-fulfillment, exactly as is a dream; moreover, it is what a dream not always is,
