into systems: Ucs, Unconscious; Pcs, Preconscious; Cs, Conscious, with borders, regions, layers and
surfaces, also showing that affect circulates as a spatial force, in a circuit.
For this TCC, the following were also selected: Chapter VII, of the Interpretation of Dreams,
1900, which works on the idea of the fi rst topic – Ics, Pcs, Cs –, showing how the psychic apparatus is
spatial with a primary organization, involving displacement and condensation; and The Unconscious,
1915a – in which Freud describes the unconscious as a system (Ucs) with its own contents and specifi c
laws, separated from the preconscious (Pcs) by a barrier that prevents direct access to consciousness
(Cs). In chapter VII, still of the Interpretation of Dreams, 1900, Freud works on the idea developed
with the fi rst topic, the idea of regression, desire and psychic apparatus. It shows how the psychic
apparatus is spatial and affect is inscribed in paths, while the subject emerges from this primary
organization.
In this chapter, Freud presents the psychic apparatus as a topology, described as a space with
separate systems – Ucs, Pcs, Cs – approaching them with the fi rst topic, in which the passage from one
system to another occurs through barriers and pathways. He adds regression (FREUD, 1915c), when
thought returns to more primitive forms of inscription, in a return to the pre-representational level,
one could say. Desire is placed as the engine of the dream and that the dream fulfi lls an unconscious
desire, according to an economic force. And the scene is when the dream organizes positions, places,
distances, so that the subject appears in a subjective position.
In this fi rst Freudian time, the subject appears as an effect of an affective position inscribed
in the body and in the situation lived, before the word. Freud speaks of the constitution of the subject

of Freudian metapsychology: Project for a Scienti c Psychology, 1895, because it is considered as the
basis from which metapsychology arises, because it introduces the studies of the psychic apparatus as
a system; chapter VII of the Interpretation of Dreams, 1900; e Drives and eir Destinies, 1915; O
Recalcamento, 1915; e Unconscious, 1915; Metapsychological Complement to the eory of Dre-
ams, 1915; Mourning and Melancholy, 1915 and Beyond the Pleasure Principle, 1920, which introdu-
ces the death drive and the revision of Freudian metapsychology. Dunker draws attention to the fact
that this classi cation is of a more classical order – insofar as it is mainly limited to the rst Freudian
topic (Ucs, Pcs, Cs) – and that, for others, it may come to present a di erent order.
