[Toward a renewal of knowledge in psychiatry].

Practice in an open hospital and liberal milieu, collocated with contemporary scientific findings, has admitted the elaboration, during thirty years, of a new form of psychiatry. This "systemal psychiatry" has been described in thirteen works successively integrated and in many French and foreign publications. Its principle characteristics are; basis, formation and emergence, production, ways of research and meaning. Since it is directly derived from the experience of the patient, its interdisciplinary origin and its permanent openness contribute to the integration of man with his physico-biopsycho-sociocultural universe, and of its methods of analogy with a more open rationality. Because of this the systemal psychiatry is productive, particularly in research.
