A discussion of the unconscious leads naturally to Freud and to a theory on subjectivity we may designate as de-centred. The unconscious reminds us that not only do we not know ourselves. In the core of our subjectivity, we have to acknowledge the notion of otherness. Re-reading Freud's text, The Unconscious, from 1915, the current author emphasises the character and function of the unconscious as radically different from what we know about conscious processes. This allows for the concept of the preconscious, which the author links to Winnicott's intermediary area and Green's tertiary processes. Taking as point of departure Freud's differentiation of word presentation and thing presentation, the author points to Freud's introduction of the term thing-cathexies of the object as designating the primal psychic representation. The Freudian perspective is broadened, encompassing the notion of otherness as discussed by Laplanche and Aulagnier. Concluding the paper, the author draws some implications for psychoanalytic technique, focusing especially on transference.
