In this chapter, Aron argues that it is in the very process of establishing a personal relationship to psychoanalytic theory and to the profession that one becomes a psychoanalyst. If our identities as psychoanalysts are established through our relationships to the psychoanalytic community, and to the values and ideals established by this society and embodied in its theories and practices, then psychoanalysis itself functions as the Third to analysts' dyadic relationships with their patients. The exploration of a clinical vignette from the perspective of three different supervisors illustrates how the theoretical and the technical form a complex system of mutual influence with the personal, the subjective, and the intersubjective and how, in the teaching and practice of psychoanalysis, these factors need to be considered together as functioning in complex and often elusive ways.
