Relational Psychoanalysis as a paradigm is presented through an exposition of the work of Donnel Stern. Stern's ideas centre around four aspects of clinical theory: the therapeutic conversation; dissociation; enactment; the emergence of new meanings. The impact on Stern of the German philosopher Gadamer's ideas is discussed. Key clinical concepts arising in Stern's work include: ‘true conversation’ as a ‘fusion of horizons’; ‘not-me’ - the repudiated parts of the self which are then enacted in the therapeutic relationship; and the emergence of new meanings when conflict, through mentalizing, is moved from the interpersonal to the intrapsychic sphere. Contrasts and comparisons with traditional psychoanalytic thinking are examined. The key defining feature of Relational Psychoanalysis is its radical interpersonal stance, insisting that there is no such thing as a mind on its own, only a mind-in-relationship.
