[Psychological interpretation of organic diseases and psychoanalytic speculation on the past].

By using examples of psychotherapy applications the author critically analyzes a tendency of speculative psychoanalytical explanation of organic illnesses on the basis of the patient's biography. Typical clinical pictures are described. Probable causes of this tendency of speculation in a psychoanalytical manner are discussed. The author also refers to the tradition of speculative theories in psychoanalysis, the meaning of behavorism for psychoanalysis as well as the denial of hereditary-genetic factors. The imponderableness of the causal meaning of biographical events is demonstrated. Impulses for training are given.
