In Truth and Judicial Forms,series of lectures presented in 1973, Michel Foucault conceive relationships between systems of truth and social practices and policies where they come from and where they invest. During the analysis of this problematic, the author notice that can only be certain types of subject of knowledge, orders of facts,realms of knowledge from social, political and historical conditions that are ground of formation of subject, realms of knowledge and relations with truth. So, the judicial forms – practices- are presented as one of the source models of truth that still circulated in society, which influence policy, daily behavior and science. Matter that would be largely developed in Discipline and Punish (1975). The present article is meant to discuss that this proposition is evident through Foucault´s work, just like in:History of madness in the classical age, Discipline and Punish, Society Must Be Defended Security, Territory and Population and TheBirth of Biopolitics Each season and each book testifying about own set of devices ad visibilities, exteriority forms, that disperse and spread, regimented in a diagram of forces – power as exercise and knowledge as regulation. Problematize the law in a non-essentialist perspective, when the historic dimension assumes the place. Think differently, offering a new form of law review. It is a bet in plurality, social practices as a producer of types of subjective, forms of knowledge and different relations between men and truth. It is a way to fortify possibilities of creation, invention and the difference.
