This academic essay aims at reflecting about the inclusion of students with special educational needs into the normal school schedule according to the works of Foucault. Therefore, this study discusses on the constitution of the subject in modernity as well as the "psy" knowledges that make intelligible the concept of abnormality. In this direction, the school, as an institution of sequester, assumes and produces new inclusion discourses that contribute to extinguishing and silencing the differences, besides enhancing the illusion that everyone is equal.
