Lien fraternel, de la psychanalyse aux mythes et aux systèmes

Abstract

This paper deals with sibling relationships, one of the three relationships in the family system. In the psychoanalytic model, Freud considered sibling antagonism as a kind of defense against the œdipal reality, whereas Eiguer emphasizes the narcissistic dimension of love among siblings. Lacan described the intrusion complex between brothers and sisters. The mythical versions of Cain and Abel and the tragic myth of Antigone by Sophocles give insight into the study of the sibling relationships. The systemic-constructivist approach stressed the importance of the help offered by siblings during the therapeutic process and their role in helping the family come to grips with pain. Two clinical cases illustrate the systemic approach to sibling relationships and their therapeutic sense.
