ABSTRACT
In a climate of unrest reinforced by misunderstandings, a few months before he died in May 1933, Sandor Ferenczi presented to his colleagues of the 12th International Congress of Psychoanalysis his testamentary article, Confusion of tongues between adults and the child. Ferenczi had already questioned, in other texts, the countertransference movements related to the treatment of patients who had suffered a real trauma. His thinking bears the trace of a confusion of tongues reactivated in the transference/countertransference relationship with S. Freud, his analyst. Under the guise of a style of writing that is sometimes naive and empirical, he delineates essential questions that are raised by the encounter between the adult and the child around infantile sexuality. He describes the confusion and identification that take place and how they encourage splitting in the child when he is invaded by adult passion.
