<p>This article discusses the use of theories and concepts in psychoanalytic therapy. It assumes that each analyst acquires a&#xa0;leading theory in training, to which further favorite concepts are added in the course of socialization. This creates personal theories that accompany and protect therapies as preconscious introjects. In difficult situations and in cases of entanglement, the appropriate concepts are called up. The author considers the use of concepts in the context of an intersubjective approach. He shows that the explicit dialogue can be understood as microscenes of an intersubjective enactment within the countertransference independent of the traditional concepts contained therein. This leads to the conclusion that traditional concepts and the intersubjective interpretation of the analytical process are not incompatible opposites but can complement each other at least in practice.</p>
