formations, and indeed from their first member, viz. dreams, is that the
unconscious--hence the psychic--occurs as a function of two separate
systems and that it occurs as such even in normal psychic life.
Consequently there are two kinds of unconscious, which we do not as yet
find distinguished by the psychologists. Both are unconscious in the
psychological sense; but in our sense the first, which we call Unc., is
likewise incapable of consciousness, whereas the second we term "Forec."
because its emotions, after the observance of certain rules, can reach
consciousness, perhaps not before they have again undergone censorship,
but still regardless of the Unc. system. The fact that in order to
attain consciousness the emotions must traverse an unalterable series of
events or succession of instances, as is betrayed through their
alteration by the censor, has helped us to draw a comparison from
spatiality. We described the relations of the two systems to each other
and to consciousness by saying that the system Forec. is like a screen
between the system Unc. and consciousness. The system Forec. not only
bars access to consciousness, but also controls the entrance to
voluntary motility and is capable of sending out a sum of mobile energy,
a portion of which is familiar to us as attention.

We must also steer clear of the distinctions superconscious and
subconscious which have found so much favor in the more recent
literature on the psychoneuroses, for just such a distinction seems to
emphasize the equivalence of the psychic and the conscious.

What part now remains in our description of the once all-powerful and
all-overshadowing consciousness? None other than that of a sensory organ
for the perception of psychic qualities. According to the fundamental
idea of schematic undertaking we can conceive the conscious perception
only as the particular activity of an independent system for which the
