The Author offers a reflection on the Freudian unconscious, taking as starting point the plurivocal quality that Freud describes in his essay The Ego and the Id. Through an examination of the evolution of Freud’s thought, the Author identifies the ascending nature of the unconscious and its permeability across the various regions of the psychic apparatus. The Author focuses on the well-known diagrams of the psychic apparatus from 1923 and 1933, and on the lesser-known ones from 1900, in which the problem of the relationship between drives and memory traces is raised. The article concludes by proposing a tripartite division of the unconscious, recalling that Freud ultimately maintains the psychic is unconscious, a statement echoed by Matte Blanco. The reference to a patient’s early memory serves as a link between the unconscious and memory, and intersects with ideas from related fields of study, touching upon the analogy between the non-repressed unconscious and implicit memory.
KEY WORDS: Repressed unconscious, non-repressed unconscious, memory traces, implicit memory, diagrams of the psychic apparatus.
