[The relevance of ethology for psychiatry].
Darwin's evolutionary theory was the starting point for ethology, associated with an impact on scientific psychiatry. Psychiatry and ethology have common scientific and methodological prerequisites: inductive and deductive methods and "gestalt theory" as a basis for observing and describing behaviour patterns with subsequent causal analysis. There have been early endeavours to anchor ethological thinking in psychiatry but this tendency did not prevail for the following reasons: on the one hand, the methodology of ethology was immature or not applicable to man, whereas on the other hand the dominating experiential phenomenological school of Karl Jaspers and Kurt Schneider stressed the privileged position of human thinking, perception, and feeling. These fundamental categories of human existence did not appear amenable to any causal ethological analysis. Psychiatry and evolutionary biology were linked in an atrocious manner during the Nazi regime, both being abused for propaganda purposes and genocide. More recently, there is a "reconciliation" of both disciplines. In psychiatric nosology, operational, behaviour-oriented diagnostic systems have been introduced; ethology has opened up for theories of learning; new subsections like human ethology and sociobiology have evolved. The seeming incompatibility of (behavioural) biological psychiatry and experiential phenomenological psychopathology may be overcome on the basis of Konrad Lorenz' evolutionary epistemology. The functional analysis of human feeling and behaviour in psychotic disorders on the basis of Jackson's theory of the evolution and dissolution of the nervous system may serve as an example. The significance of an "ethological psychiatry" for diagnostic and therapeutical processes of psychiatric disorders derive from prognostic possibilities and the analysis of non-verbal communication in therapist-patient-interactions, but have not yet been systematically investigated.
