It is in this context that Lacan introduces the concept of object a, which became one of the
pillars of his theory. It is the object cause of desire, not an object that can be fully obtained, but a point
of lack that moves the subject. Object a is a leftover from the operation of symbolic castration—a lost
part of the subject that returns as the cause of his desire. It can manifest itself in the look, in the voice,
in the body, in dreams, in fantasies, in love — but it is never reduced to a real object (Lacan, 1985;
Jorge; Ferreira, 2005). Precisely because it never completes itself, it keeps the desire moving.
Desire, therefore, is the very structure of the subject in Lacanian theory. It is lack, it is
displacement, it is continuous tension. The human subject is, essentially, a desiring subject — and this
is what constitutes him, what makes him live and suffer, what moves him towards the Other, in search
of the impossible (Fink, 2015; Vanier, 2005).
LANGUAGE AS A STRUCTURE OF THE UNCONSCIOUS
If there is something that denes Lacanian psychoanalysis, it is the afrmation that the
unconscious is structured as a language (Araújo, 2001; Lacan, 1998). This is not a simple metaphor, but
a rigorous theoretical conception, sustained by dialogue with structural linguistics. Lacan appropriated
the ideas of Ferdinand de Saussure and Roman Jakobson to develop his theory, according to which the
unconscious works through signiers, operating with displacements, condensations and metaphors —
just like the mechanisms of language (Ducrot; Todorov, 1974; Saussure, 1945).
Unlike the initial Freudian notion of “repressed content”, Lacan conceives the unconscious as
a chain of signiers. This chain is not irrational, but follows its own logic — the logic of the unconscious,
which manifests itself in dreams, faulty acts, symptoms, and formations of the unconscious in general
(Fink, 1999; Jorge, 2008). The analyst, therefore, becomes a reader of the subject’s speech, someone
who listens to what is said and, above all, what escapes — what the subject does not know what he
says.
For Lacan, the signier is more determinant than the signied. What matters in psychoanalysis
