so 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withdrawn from the Forec., becomes the preliminary condition of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the energy has been withdrawn from the thoughts of transference in the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 pow
