[Taking offense and illness - the pathology of interaction as seen by a psychiatrist (author's transl)].

Theories of interaction matter not only for psychoreactive disturbances, pathologic forms and sequelae of interaction may influence or even determine origin and course of psychoses. Present treatment or schizophrenic problems contains the danger that psychogenetic theories are sharply confronted with biologic concepts. As fas as we know today both are equally ligitimate. Purely psychogenetic theories like that of Bateson do not always avoid the temptation to ask and answer questions of guilt. This is therapeutically nearly always useless and may lead to arrogance. Psychotherapy of endogenous psychoses - up to now mostly only a demand - cannot be realized by adopting a model theory. It is more a question of the attitude of the physician.
