The present work integrates the line of research Theory of Law, Ethics and Construction of Subjectivity and aims to develop the relationship between subjectivity and social bond in the family and school institutions from a psychoanalytic theory perspective. The purpose of this work is to analyze through the views of Freud and Winnicott the different anthropological and constitutional conceptions of subjectivity and to outline the possibilities of social bonds, that is, to connect and to empathize with one another, and the possible ethical consequences of adopting one or other conception. What is sought hereby as a broader context is to point out the paradigm shift between the thoughts of Freud and Winnicott, alternating the perspective of an analysis focused on Freud s conception of the individual drive, to Winnicott s relational aspect of the environment and the institutions which constitute subjectivities. This work s outlines are based on four issues: (i) the conception of the subject in Freud leads to the need for an internal authority, the superego, and for an external authority, the State, to control its drives, thus evidencing the ethics of the law; (ii) the concept of the subject in Winnicott is based on a relational conception of the subject, emphasizing the role of the environment in this process, which is circumscribed by the ethics of care; (iii) the social bond assumes the inseparability between subjectivity and social, perceiving them as interconnected phenomena and acknowledging that, on the one hand, the social environment acts and produces subjectivities and, on the other, the assumptions used in the conception of the subject directly influence the institutions and the form of interaction and reciprocity among the subjects; (iv) socializing institutions, such as the school and the family, when taking a stance based on the ethics of care, embrace the singularities, allow the effectiveness of the social bond and the emersion of the subject. In order to illustrate this theme with practical outlines, this work will use two cases from the book The Brazilian Ralé by Jessé Souza, which allow a reflection on the construction of subjectivities under the perspectives of the family and school institutions.
