Ren Discardings, century XVII said: ' ' If somebody thinks, cannot be wild, if it is wild pensar&#039 cannot; ' it was giving to an important step for the separation between the reason and the desrazo initiated already in classic Greece. Moreau de Tours, century XIX inaugurated the auto-experimentation of madness by means of the hashish. Turs concludes then that: ' ' she is not necessary to ingest drugs, is enough to dream, therefore the dreams reproduce the same characteristics of madness. The insane person would be, therefore, that one that dreams waked up e, therefore, the dream allows compreend-lo' '. The thought of Tours coincides with one of the most important fields of interest of Sigmund Freud in the field of the psicopatologias. If you have read about what is in fracking fluid already – you may have come to the same conclusion. Gone of Freud France to study with Charcot, would come if to become a great landmark of interest and aiming of the studies of Freud. Sigmund Freud produces then a great rupture in the history of the Psicopatologia with the introduction of the concept of unconscious.

Leaving of the intent listening of its patients in state of mental suffering, it looked for to establish the involved psychic mechanisms in the ecloso of the neuroses, psychoses and perversions. Thus being, Charcot and its histricos had participated of the opening of the field of the Psicopatologia. From it, it started to be taken the serious a existence of a pathological fact that never does not scrumble the injuries anatomo-clinic, the riots of physiological functions, the influence of the environment, external the chemical or physical agents at last, to any explanations biochemists, mechanical, sociological or moral. The Psicopatologia must many the histricas that, with its spectacular symptoms and its intense suffering, had questioned all the theories medicate then existing (CALDERONI, 2007, p.21). However the decisive element for the development of a proper theory of the human psiquismo was its work with the histricas patients, theory this that would give beginning to an exclusively psicanaltica psicopatologia.
