With the aim to criticize the concept of reconciliation, understood within the field of knowledge of transitional justice, this thesis observes the post-dictatorship context in Brazil, with emphasis on the related instruments. It notes that there is a link in speeches and practices, in theory and in concrete cases, between reconciliation and national identity. It realizes that there is a problem in this relationship: while etymologically different, when made analogues they produce oblivion, appeasement, pacification, and can generate what objectively in the beginning was not wanted: the return of authoritarian regimes. To analyze the Brazilian panorama and the definitions of the three highlighted terms - transitional justice, reconciliation and national identity -, is used Gilles Deleuze s political philosophy. As a way of creating a new ontology, it brings discussions about law and institutions, a new way of analyzing micropolitics and how collective enunciation and order words act. When examining the meaning of mechanisms and discourses in the Brazilian transition - investigating the production of the Amnesty Law, the steps to and of the Constituent Assembly, the CEMDP, the Amnesty Commission, the lawsuits and the CNV -, it sets up the form and content of the lines of hard segmentation, flexible and of flight, as well as the State s captures due to the capitalist axiomatic. This study explains that there was no political reconciliation in the country, that transitional justice is unfinished, that national identity is a discourse to omit violence and that silencing the past is not enough for its non-repetition.
