[The understanding of psychopathology and the role of phenomenology. Contribution to a controversy].

The sense of psychopathology is interpreted as the development of a descriptive language, that allowed the approach to the psychiatric disease in the context of natural sciences. The phenomenology was introduced as a methodological tool for the improvement of this language. Since then this topic has been present in the foundations problems of psychiatry. In this paper the discussion is set towards the influence of phenomenology in psychopathology, as a controversy between two opposite points of view. The authors establish their own arguments about the limits of psychopathological knowledge and psychiatric experience.
