[The own and the foreign. Philosophical and clinical aspects].

Introduction: The own and the foreign are not actually philosophical basic concepts, but rather topoi, since they always relate to each other relationally and this always in relation to the perspective in which we experience something as foreign or own. Strangeness concerns us, irritates, unsettles, does not leave us alone, but at the same time, as strangeness, it eludes determination or cannot be determined, since it would then lose its strangeness. It has the character of a relapse, is paradoxically determined by presence in withdrawal, cannot be completely classified, is thus "extraordinary" and singular. It is incomparable and yet related to one's own. The article attempts a philosophical approach to the particularity of the foreign - also in ourselves - in order to clarify the theoretical considerations for the understanding of a concrete clinical case from a psychiatric-transcultural consultation. This case deals with the question of non-understanding in the face of a behavior of the patient that is alienating for the therapist as well as for the patient. This leads to the question whether and how this non-understanding could still be understandable.
