Interpersonal approaches to the concept of a core self are explored in a review of Narcissism and the Interpersonal Self (John Fiscalini and Alan Grey, Editors). The role of self as system and self as identity—both the interpersonal, adaptive self and the personal, core self—is used to understand the evolution of the Interpersonal School and its varied approaches to narcissism. A formulation integrating subjectively and objectively based models is proposed whereby the “core” self may be understood as the totality and integrity between internal, personal self and reflected, interpersonal self. Narcissism involves an alienation of the reflected self from the inner self, which leads to a particular set of dynamics to regulate self-esteem.
