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 al
