The model of the so-called Paris School of Psychosomatics was the one that acquired more prestige in the psychoanalytic field to approach the psychosomatic diseases. This model is based on the thesis that physical illness is the result of a insufficiency of mental functioning, a condition that causes the body to become the outlet for the accumulation of excitations triggered by a traumatic experience. Based on a critical analysis of the French model, the present thesis had the main objective of outlining another psychoanalytic model of approach to somatic illness based on an articulation between contributions of three authors of the psychoanalytic tradition (Sándor Ferenczi, Georg Groddeck and Donald Woods Winnicott) and some contributions extracted from the philosophy of Benedictus of Spinoza. Throughout the work, we developed articulations between the four authors, highlighting the basic elements of the framework that we are proposing, namely: (1) body and psyche are taken as two aspects of an integral reality conceived as an open system in regime of lasting mutual affection with the environment; (2) all forms of illness are conceived as being psychosomatic; (3) all forms of illness are symbolic in the sense that they are the expression of processes of psychosomatic affectation with the environment, which occur not only in the body (in its physiological and affective dimensions) but also in the psyche, which constitutes a movement of imaginative elaboration of the bodily experience.
