Psychological concepts used by psychosocial professionals are not "things in themselves," but rather explanations and hypotheses that we use to make sense of the world. This idea, as demonstrated by Furman and Ahola in their simple and clear examples, has implications for the fundamental understanding of therapy and therapeutic possibilities. The authors compare psychotherapists to pickpockets among nudists. In order to steal what is in the pockets, the therapist must first "sew up" that pocket and cooperate with clients in the process. Furman and Ahola provide practical and knowledgeable examples, focusing on solutions rather than getting bogged down in problems. They do not shy away from sacred cows. "Harmful effects of psychotherapeutic assumptions" come into focus just as much as the "return of the Fr.".
