The author sees H.S. Sullivan's (1892–1949) interpersonal theory as the best theoretical framework for the contemporary intersubjective perspective in psychoanalysis and presents the former in its pluridimensional articulation. After having extended Freud's therapeutic approach to psychotic patients, Sullivan developed both a developmental psychology and a psychoanalytic and psychotherapeutic technique based on the “interpersonal field” as the basic unit of study. To the pluridimensional character of his theory also belongs its application to the cultural and social aspects of our personal identity. Having the contemporary psychoanalytic authors who shaped the intersubjective perspective limited themselves to the clinical dimension, Sullivan's interpersonal theory can still provide the theoretical framework that any psychoanalytic perspective needs.
