Starting from the way psychoanalytical theory has death instinct and its non-pathologiocal evolution, the article examines the evolution af addictions, espacially how these can be sublimated into an identity solution. Clinical examples illustrate this. Reversely, starting from the clinic and the protocol of psychotherapy for drugs addicts as was elaborated in the 90’s, the author shows that the main theorical principles for treating such patients – ever before addictology existed as much – are still valid, as regard the notions of temporality, sdis-sonance or approximation.
Summary. The article is about cultural transmission seen from two different approaches. First what is passed on by on foreign student to his/her thesis supervisor : the author argues that there seems to exist a connexion between decentring and dis-semblance. He then elaborats around the notion of dissymetry witch may allow a transformation of representations. Secondly he writes about a similar dissymerty, in the clinic existing between patient and therapist, which enables the therapist to circumscribe the field of speech, movement or affects, bearing in mind that the therapeutic framework requires constant reassessment. Througout the article, attention is paid to the idea that the student or the patient’s cultures cannot be reduced to his/her own cultural identity, but to allow full scope to the Uncanny.
