1. The six Congresses of the Allgemeine Äerztliche Gesellschaft für Psychotherapie were open to discussions of the basic principles of psychotherapy; they were guided by clinical, experimental, etiological, and prognostic research which led to some clarification of the indications for the selection of method.2. Mere professions of creed were more and more excluded.3. Research into the degree of agreement and the reasons and causes of disagreement of the experts in psychotherapy were encouraged.4. Humane viewpoints, the true basis and justification of psychotherapy, were stressed in the handling of the traumatic neurotic, the social neurotic, the criminal, the neurotic whom the clergyman may see.5. A psychotherapy of the psychoses was outlined and weighed critically.6. Psychotherapeutic research in the various medical branches was encouraged.Abstract Teaser
