In 1889, Freud decides to analizar itself and discovers ' ' real road for inconsciente' ' (the dreams) through the free association, that is, to say any thing that came the mind without any censorship. During one year, Freud adentrou in its unconscious one and discovered a imensido of restrained and painful feelings: ' ' We are the destination of all to direct the first sexual impulse for our mother and the first hatred and desire of death against ours pai.' ' The Complex appears thus of dipo. In 1901, Freud writes its more important workmanship ' ' The Interpretation of the Sonhos' ' , through the register of its discoveries and its proper dreams, its auto-analysis. More ahead, it publishes the book ' ' On the psicopatologia of cotidiano' ' , evidencing that the defective act was as symptom, commitment constitution enters the conscientious intention of the person and the restrained one. In 1920, Freud launches the workmanship ' ' Beyond the beginning of the Prazer' ' , disclosing that it has an instinct in the men beyond the libido, an aggressive instinct, of death. Being thus developed the Theory of Eros and Tanatos.
Tanatos is the aggressive and destructive instinct, as instinctive part of the human being and Eros the constructive instinct. It affirms that the human being has a natural instinct of death and that the same it must be controlled. The freudianos studies take to reflect us it on we ourselves: ' ' Which our true history? ' '. The search for true ' ' eu' ' perpassa for the obscure ways of the mind, the unconscious call, that Freud appraised so well in id, ego and superego. Id, as representative of our more primitive desires, the ego is between id and superego, pondering its requirements and superego that against-it acts to id, represents internalizados the moral and ethical thoughts. The psicanaltico process, focused so well and structuralized for Freud, in them takes the discovery of our essence, through the ways of the hypnosis, the free association and primordially for the interpretation of the dreams, which will go to set in motion the unconscious one to arrive the cure of the neuroses and the reinforcement of the ego, having as deep cloth of one ' ' set analtico' '.
