[A new approach to psychosis. Is psychosis a disorder of mental reality?].

World's knowledge is but imperfectly intelligible to thinking beings by binding Possible with Reality of the experience meaning what resists them (matter or form) as sensible organ, while time perception remains out of feeling. Although the Reason seeks coherence in its seizing of the World, only consisting in experiences, yet the various experiences are not ordered a-priori towards coherence as an aim. The Reason ascribes the experiences to be pre-classified according to three modes: Continuity-Successiveness-Reversibility, connecting a physical fact (temporarily) to a thought fact (classifying). This motion towards a coherent understanding of the World proceeds by leaps over representations in three ways: 1-induction without requirement nor warranties. 2-analogical interpretation in which the middle term offers a slight validity. 3-demonstration where experiences get authentified but needs term successiveness undoubtedly marked in time. In case of a time mark deficiency, the demonstrative way gets out of warranty. The subject loses his free choice between Possible and Reality, causing psychosis. Yet the thought, getting improper to appreciate and correct the less gap between itself and experiences becomes else: thence, filtered by matter, it responds to chemotherapeutic strategies. The various symptoms in Psychosis can be brought to a selective deficit of the experience's pre classifying such as: -lack of "reversibility" troubling the course of thoughts, causing hermetism etc... -lack of "continuity" making easier experience materiality causing hallucinations. -defect of "successiveness" supporting the Possible for loss of the Reality causing delusion conviction.(ABSTRACT TRUNCATED AT 250 WORDS)
