With roots stemming both from the body and from the interaction with the environment, the psyche organizes itself from the experience lived by the body of the baby which, upon birth, finds itself immersed in the symbolic universe of human relations. In the psychoanalytic perspective, the notions of pleasure and unpleasure are the basis of the ordering of psychic activity, which leads us to take them as departure point of this investigation, considering them, at once, as both bodily and psychic expressions, necessarily involving a relational character. This work consists in an articulation between the Freudian conception of the psychic apparatus and the role of the environment, prioritizing the experience which leads to the organization of the ego.
