Charcot, Janet, and French Models of Psychopathology.

Jean-Martin Charcot (1825-1893), thanks to his insight as a clinician can be said to be one of the precursors of scientific psychology. Charcot's 30 years of activity at La Salpêtrière hospital display an intellectual trajectory that decisively changed the idea of human psychology by favouring the emergence of two concepts: the subconscious and the unconscious. It was his collaboration with Pierre Janet (1859-1947), a philosopher turned physician, that led to this evolution, relying on the search for hysteria's aetiology, using hypnosis as a method of exploration. Focusing on clinical psychology that was experimental and observational, Janet built a theory of psychic automatism, "the involuntary exercise of memory and intelligence" leading to "independence of the faculties, freed from personal power." From all that came the idea of the subconscious, a functioning as a passive mental mechanism, resulting from a more or less temporary dissociation of previously associated mental content.
