in their entirety, and, proceeding from one conception to the other,
they thus form single presentations endowed with marked intensity.
Through the repeated recurrence of this process the intensity of an
entire train of ideas may ultimately be gathered in a single
presentation element. This is the principle of _compression or
condensation_. It is condensation that is mainly responsible for the
strange impression of the dream, for we know of nothing analogous to it
in the normal psychic life accessible to consciousness. We find here,
also, presentations which possess great psychic significance as
junctions or as end-results of whole chains of thought; but this
validity does not manifest itself in any character conspicuous enough
for internal perception; hence, what has been presented in it does not
become in any way more intensive. In the process of condensation the
entire psychic connection becomes transformed into the intensity of the
presentation content. It is the same as in a book where we space or
print in heavy type any word upon which particular stress is laid for
the understanding of the text. In speech the same word would be
pronounced loudly and deliberately and with emphasis. The first
comparison leads us at once to an example taken from the chapter on "The
Dream-Work" (trimethylamine in the dream of Irma's injection).
Historians of art call our attention to the fact that the most ancient
historical sculptures follow a similar principle in expressing the rank
of the persons represented by the size of the statue. The king is made
two or three times as large as his retinue or the vanquished enemy. A
piece of art, however, from the Roman period makes use of more subtle
means to accomplish the same purpose. The figure of the emperor is
placed in the center in a firmly erect posture; special care is bestowed
on the proper modelling of his figure; his enemies are seen cowering at
his feet; but he is no longer represented a giant among dwarfs. However,
the bowing of the subordinate to his superior in our own days is only an
echo of that ancient principle of representation.
The direction taken by the condensations of the dream is prescribed on
the one hand by the true foreconscious relations of the dream thoughts,
an the other hand by the attraction of the visual reminiscences in the
unconscious. The success of the condensation work produces those
intensities which are required for penetration into the perception
systems.
2. Through this free transferability of the intensities, moreover, and
in the service of condensation, _intermediary
presentations_--compromises, as it were--are formed (_cf._ the numerous
examples). This, likewise, is something unheard of in the normal
presentation course, where it is above all a question of selection and
retention of the "proper" presentation element. On the other hand,
composite and compromise formations occur with extraordinary frequency
when we are trying to find the linguistic expression for foreconscious
thoughts; these are considered "slips of the tongue."
3. The presentations which transfer their intensities to one another are
_very loosely connected_, and are joined together by such forms of
association as are spurned in our serious thought and are utilized in
the production of the effect of wit only. Among these we particularly
find associations of the sound and consonance types.
4. Contradictory thoughts do not strive to eliminate one another, but
remain side by side. They often unite to produce condensation _as if no
contradiction_ existed, or they form compromises for which we should
never forgive our thoughts, but which we frequently approve of in our
actions.
These are some of the most conspicuous abnormal processes to which the
thoughts which have previously been rationally formed are subjected in
the course of the dream-work. As the main feature of these processes we
recognize the high importance attached to the fact of rendering the
occupation energy mobile and capable of discharge; the content and the
actual significance of the psychic elements, to which these energies
adhere, become a matter of secondary importance. One might possibly
think that the condensation and compromise formation is effected only in
the service of regression, when occasion arises for changing thoughts
into pictures. But the analysis and--still more distinctly--the
synthesis of dreams which lack regression toward pictures, _e.g._ the
dream "Autodidasker--Conversation with Court-Councilor N.," present the
same processes of displacement and condensation as the others.
Hence we cannot refuse to acknowledge that the two kinds of essentially
different psychic processes participate in the formation of the dream;
one forms perfectly correct dream thoughts which are equivalent to
normal thoughts, while the other treats these ideas in a highly
surprising and incorrect manner. The latter process we have already set
apart as the dream-work proper. What have we now to advance concerning
this latter psychic process?
We should be unable to answer this question here if we had not
penetrated considerably into the psychology of the neuroses and
especially of hysteria. From this we learn that the same incorrect
psychic processes--as well as others that have not been
enumerated--control the formation of hysterical symptoms. In hysteria,
too, we at once find a series of perfectly correct thoughts equivalent
to our conscious thoughts, of whose existence, however, in this form we
can learn nothing and which we can only subsequently reconstruct. If
they have forced their way anywhere to our perception, we discover from
the analysis of the symptom formed that these normal thoughts have been
subjected to abnormal treatment and _have been transformed into the
symptom by means of condensation and compromise formation, through
superficial associations, under cover of contradictions, and eventually
over the road of regression_. In view of the complete identity found
between the peculiarities of the dream-work and of the psychic activity
forming the psychoneurotic symptoms, we shall feel justified in
transferring to the dream the conclusions urged upon us by hysteria.
From the theory of hysteria we borrow the proposition that _such an
abnormal psychic elaboration of a normal train of thought takes place
only when the latter has been used for the transference of an
unconscious wish which dates from the infantile life and is in a state
of repression_. In accordance with this proposition we have construed
the theory of the dream on the assumption that the actuating dream-wish
invariably originates in the unconscious, which, as we ourselves have
admitted, cannot be universally demonstrated though it cannot be
refuted. But in order to explain the real meaning of the term
_repression_, which we have employed so freely, we shall be obliged to
make some further addition to our psychological construction.
We have above elaborated the fiction of a primitive psychic apparatus,
whose work is regulated by the efforts to avoid accumulation of
excitement and as far as possible to maintain itself free from
excitement. For this reason it was constructed after the plan of a
reflex apparatus; the motility, originally the path for the inner bodily
change, formed a discharging path standing at its disposal. We
subsequently discussed the psychic results of a feeling of
gratification, and we might at the same time have introduced the second
assumption, viz. that accumulation of excitement--following certain
modalities that do not concern us--is perceived as pain and sets the
apparatus in motion in order to reproduce a feeling of gratification in
which the diminution of the excitement is perceived as pleasure. Such a
current in the apparatus which emanates from pain and strives for
pleasure we call a wish. We have said that nothing but a wish is capable
of setting the apparatus in motion, and that the discharge of excitement
in the apparatus is regulated automatically by the perception of
pleasure and pain. The first wish must have been an hallucinatory
occupation of the memory for gratification. But this hallucination,
unless it were maintained to the point of exhaustion, proved incapable
of bringing about a cessation of the desire and consequently of securing
the pleasure connected with gratification.
Thus there was required a second activity--in our terminology the
activity of a second system--which should not permit the memory
occupation to advance to perception and therefrom to restrict the
psychic forces, but should lead the excitement emanating from the
craving stimulus by a devious path over the spontaneous motility which
ultimately should so change the outer world as to allow the real
perception of the object of gratification to take place. Thus far we
have elaborated the plan of the psychic apparatus; these two systems are
the germ of the Unc. and Forec, which we include in the fully developed
apparatus.
In order to be in a position successfully to change the outer world
through the motility, there is required the accumulation of a large sum
of experiences in the memory systems as well as a manifold fixation of
the relations which are evoked in this memory material by different
end-presentations. We now proceed further with our assumption. The
manifold activity of the second system, tentatively sending forth and
retracting energy, must on the one hand have full command over all
memory material, but on the other hand it would be a superfluous
expenditure for it to send to the individual mental paths large
quantities of energy which would thus flow off to no purpose,
diminishing the quantity available for the transformation of the outer
world. In the interests of expediency I therefore postulate that the
second system succeeds in maintaining the greater part of the occupation
energy in a dormant state and in using but a small portion for the
purposes of displacement. The mechanism of these processes is entirely
unknown to me; any one who wishes to follow up these ideas must try to
find the physical analogies and prepare the way for a demonstration of
the process of motion in the stimulation of the neuron. I merely hold to
the idea that the activity of the first [Greek: Psi]-system is directed
_to the free outflow of the quantities of excitement_, and that the
second system brings about an inhibition of this outflow through the
energies emanating from it, _i.e._ it produces a _transformation into
dormant energy, probably by raising the level_. I therefore assume that
under the control of the second system as compared with the first, the
course of the excitement is bound to entirely different mechanical
conditions. After the second system has finished its tentative mental
work, it removes the inhibition and congestion of the excitements and
allows these excitements to flow off to the motility.
An interesting train of thought now presents itself if we consider the
relations of this inhibition of discharge by the second system to the
regulation through the principle of pain. Let us now seek the
counterpart of the primary feeling of gratification, namely, the
objective feeling of fear. A perceptive stimulus acts on the primitive
apparatus, becoming the source of a painful emotion. This will then be
followed by irregular motor manifestations until one of these withdraws
the apparatus from perception and at the same time from pain, but on the
reappearance of the perception this manifestation will immediately
repeat itself (perhaps as a movement of flight) until the perception has
again disappeared. But there will here remain no tendency again to
occupy the perception of the source of pain in the form of an
hallucination or in any other form. On the contrary, there will be a
tendency in the primary apparatus to abandon the painful memory picture
as soon as it is in any way awakened, as the overflow of its excitement
would surely produce (more precisely, begin to produce) pain. The
deviation from memory, which is but a repetition of the former flight
from perception, is facilitated also by the fact that, unlike
perception, memory does not possess sufficient quality to excite
consciousness and thereby to attract to itself new energy. This easy and
regularly occurring deviation of the psychic process from the former
painful memory presents to us the model and the first example of
_psychic repression_. As is generally known, much of this deviation from
the painful, much of the behavior of the ostrich, can be readily
demonstrated even in the normal psychic life of adults.
By virtue of the principle of pain the first system is therefore
altogether incapable of introducing anything unpleasant into the mental
associations. The system cannot do anything but wish. If this remained
so the mental activity of the second system, which should have at its
disposal all the memories stored up by experiences, would be hindered.
But two ways are now opened: the work of the second system either frees
itself completely from the principle of pain and continues its course,
paying no heed to the painful reminiscence, or it contrives to occupy
the painful memory in such a manner as to preclude the liberation of
pain. We may reject the first possibility, as the principle of pain also
manifests itself as a regulator for the emotional discharge of the
second system; we are, therefore, directed to the second possibility,
namely, that this system occupies a reminiscence in such a manner as to
inhibit its discharge and hence, also, to inhibit the discharge
comparable to a motor innervation for the development of pain. Thus from
two starting points we are led to the hypothesis that occupation through
the second system is at the same time an inhibition for the emotional
discharge, viz. from a consideration of the principle of pain and from
the principle of the smallest expenditure of innervation. Let us,
however, keep to the fact--this is the key to the theory of
repression--that the second system is capable of occupying an idea only
when it is in position to check the development of pain emanating from
it. Whatever withdraws itself from this inhibition also remains
inaccessible for the second system and would soon be abandoned by virtue
of the principle of pain. The inhibition of pain, however, need not be
complete; it must be permitted to begin, as it indicates to the second
system the nature of the memory and possibly its defective adaptation
for the purpose sought by the mind.
The psychic process which is admitted by the first system only I shall
now call the _primary_ process; and the one resulting from the
inhibition of the second system I shall call the _secondary_ process. I
show by another point for what purpose the second system is obliged to
correct the primary process. The primary process strives for a discharge
of the excitement in order to establish a _perception_ identity with the
sum of excitement thus gathered; the secondary process has abandoned
this intention and undertaken instead the task of bringing about a
_thought identity_. All thinking is only a circuitous path from the
memory of gratification taken as an end-presentation to the identical
occupation of the same memory, which is again to be attained on the
track of the motor experiences. The state of thinking must take an
interest in the connecting paths between the presentations without
allowing itself to be misled by their intensities. But it is obvious
that condensations and intermediate or compromise formations occurring
in the presentations impede the attainment of this end-identity; by
substituting one idea for the other they deviate from the path which
otherwise would have been continued from the original idea. Such
processes are therefore carefully avoided in the secondary thinking. Nor
is it difficult to understand that the principle of pain also impedes
the progress of the mental stream in its pursuit of the thought
identity, though, indeed, it offers to the mental stream the most
important points of departure. Hence the tendency of the thinking
process must be to free itself more and more from exclusive adjustment
by the principle of pain, and through the working of the mind to
restrict the affective development to that minimum which is necessary as
a signal. This refinement of the activity must have been attained
through a recent over-occupation of energy brought about by
consciousness. But we are aware that this refinement is seldom
completely successful even in the most normal psychic life and that our
thoughts ever remain accessible to falsification through the
interference of the principle of pain.
This, however, is not the breach in the functional efficiency of our
psychic apparatus through which the thoughts forming the material of the
secondary mental work are enabled to make their way into the primary
psychic process--with which formula we may now describe the work leading
to the dream and to the hysterical symptoms. This case of insufficiency
results from the union of the two factors from the history of our
evolution; one of which belongs solely to the psychic apparatus and has
exerted a determining influence on the relation of the two systems,
while the other operates fluctuatingly and introduces motive forces of
organic origin into the psychic life. Both originate in the infantile
life and result from the transformation which our psychic and somatic
organism has undergone since the infantile period.
When I termed one of the psychic processes in the psychic apparatus the
primary process, I did so not only in consideration of the order of
precedence and capability, but also as admitting the temporal relations
to a share in the nomenclature. As far as our knowledge goes there is no
psychic apparatus possessing only the primary process, and in so far it
is a theoretic fiction; but so much is based on fact that the primary
processes are present in the apparatus from the beginning, while the
secondary processes develop gradually in the course of life, inhibiting
and covering the primary ones, and gaining complete mastery over them
perhaps only at the height of life. Owing to this retarded appearance of
the secondary processes, the essence of our being, consisting in
unconscious wish feelings, can neither be seized nor inhibited by the
foreconscious, whose part is once for all restricted to the indication
of the most suitable paths for the wish feelings originating in the
unconscious. These unconscious wishes establish for all subsequent
psychic efforts a compulsion to which they have to submit and which
they must strive if possible to divert from its course and direct to
higher aims. In consequence of this retardation of the foreconscious
occupation a large sphere of the memory material remains inaccessible.
Among these indestructible and unincumbered wish feelings originating
from the infantile life, there are also some, the fulfillments of which
have entered into a relation of contradiction to the end-presentation of
the secondary thinking. The fulfillment of these wishes would no longer
produce an affect of pleasure but one of pain; _and it is just this
transformation of affect that constitutes the nature of what we
designate as "repression," in which we recognize the infantile first
step of passing adverse sentence or of rejecting through reason_. To
investigate in what way and through what motive forces such a
transformation can be produced constitutes the problem of repression,
which we need here only skim over. It will suffice to remark that such a
transformation of affect occurs in the course of development (one may
think of the appearance in infantile life of disgust which was
originally absent), and that it is connected with the activity of the
secondary system. The memories from which the unconscious wish brings
about the emotional discharge have never been accessible to the Forec.,
and for that reason their emotional discharge cannot be inhibited. It
is just on account of this affective development that these ideas are
not even now accessible to the foreconscious thoughts to which they have
transferred their wishing power. On the contrary, the principle of pain
comes into play, and causes the Forec. to deviate from these thoughts of
transference. The latter, left to themselves, are "repressed," and thus
the existence of a store of infantile memories, from the very beginning
withdrawn from the Forec., becomes the preliminary condition of
repression.
In the most favorable case the development of pain terminates as soon as
the energy has been withdrawn from the thoughts of transference in the
Forec., and this effect characterizes the intervention of the principle
of pain as expedient. It is different, however, if the repressed
unconscious wish receives an organic enforcement which it can lend to
its thoughts of transference and through which it can enable them to
make an effort towards penetration with their excitement, even after
they have been abandoned by the occupation of the Forec. A defensive
struggle then ensues, inasmuch as the Forec. reinforces the antagonism
against the repressed ideas, and subsequently this leads to a
penetration by the thoughts of transference (the carriers of the
unconscious wish) in some form of compromise through symptom formation.
But from the moment that the suppressed thoughts are powerfully occupied
by the unconscious wish-feeling and abandoned by the foreconscious
occupation, they succumb to the primary psychic process and strive only
for motor discharge; or, if the path be free, for hallucinatory revival
of the desired perception identity. We have previously found,
empirically, that the incorrect processes described are enacted only
with thoughts that exist in the repression. We now grasp another part of
the connection. These incorrect processes are those that are primary in
the psychic apparatus; _they appear wherever thoughts abandoned by the
foreconscious occupation are left to themselves, and can fill themselves
with the uninhibited energy, striving for discharge from the
unconscious_. We may add a few further observations to support the view
that these processes designated "incorrect" are really not
falsifications of the normal defective thinking, but the modes of
activity of the psychic apparatus when freed from inhibition. Thus we
see that the transference of the foreconscious excitement to the
motility takes place according to the same processes, and that the
connection of the foreconscious presentations with words readily
manifest the same displacements and mixtures which are ascribed to
inattention. Finally, I should like to adduce proof that an increase of
work necessarily results from the inhibition of these primary courses
from the fact that we gain a _comical effect_, a surplus to be
discharged through laughter, _if we allow these streams of thought to
come to consciousness_.
