A lecture given by Silvano Arieti (1914-1981) on December 11, 1962, in Milan at a training course on "Problems of psychotherapy" is reprinted. This course was organized by the "Milan Group for the Advancement of Psychotherapy" (that later took the name of Psicoterapia e Scienze Umane). Arieti’s lecture is preceded by an introduction of Pier Francesco Galli (who organized that course) and divided in two parts, each followed by the transcription of the discussions held at the time among the participants (a total of 22 interventions). Arieti describes his psychotherapeutic technique for schizophrenia, emphasizing the differences from the techniques of - among others - Frieda Fromm-Reichmann, Marguerite Sechehaye, John Rosen and the existentialist approaches. In particular, Arieti talks of his technique for hallucinations and delusions, the process of "concretization" in schizophrenic thought, drug therapy, relationship with families, outcome criteria, treatment termination, and so on.
