This text explores the evolution of the notion of trauma in Freud’s work and of its decisive import for the organization of psychic functioning through a two-stage process called the après-coup. By following the three steps of Freud’s theory of the drives, the author shows that the conception of the traumatic is gradually internalized to become a basic quality of all drives as a tendency to return to an earlier state, and ultimately an organic, inanimate state. An open question remains in Freud about this tendency’s relation to Eros, and therefore to the links between Eros and the traumatic state. This question has remained latent within the psychoanalytic community. The author proposes to conceive of Eros as an infinitely extensible tendency that needs containing in order for it to contribute to evolving inscriptions. Thus is outlined one traumatic state as a return to the inorganic and another traumatic state as an infinite extensibility, both being transformed by the superego and its imperatives in order to generate all life forms.
