[Systematic psychiatry or 35 years of hospital clinical research].

In an ere in which man is beginning to master and make his way into the various systems which surround him (atom, cosmic exploration, organ transplant, genetic manipulations...), a clinical practice which would remain centered on the various forms and apparent characteristics of psychic dysfunctioning, has become anachronical. Since 35 years, the author has been trying to introduce gradually within psychiatry, specific processes which would confer to it more scientific status. The disentanglement from traditional clinical practice, made easier by the fact of working in the open department of a general hospital as well as the perfecting of an adequate method structurating observation with modern logical-mathematic notions, enabled him to elaborate a new clinical psychiatry, open to present techniques and more strict interdisciplinary research. The chronological account of the steps which have been taken allows a simplified synthesis of this new psychiatry.
