What is individual competence? Freud highlighted the unconscious as an istance that conscience bars, but which has to take into account: an istance that continually comes to conscience, bypassing the barriers, before being rejected. In some Cases, among those that Freud decides to publish, patients use their unconscious to solute the pathology through the psychoanalytical method which Freud discovered after moving away from the hypnosis practiced until then together with other direct psychic therapies. Recognizing being himself called, Jacques Lacan takes up the question posed by Freud about the inevitability of pathological masochism, and he deals carefully with this, leaving us ample testimony: it was during the translation of his Écrits' that Giacomo B. Contri - already an analysand of Lacan and at that time also a student - came to identify for his own work the issues unanswered by Lacan himself, until he was ready to publish Il pensiero di natura. Dalla psicoanalisi al pensiero giuridico. It is the juridical, as a matter of fact, as a conclusive thinking that analytical work allows us to unravel non fruitlessly, which is also able to resolve the economic issue outlined by Freud.
