Without extending the historical analysis, this article analyzes the relationship between the legal concept of person with regard to the notion of living independently. The concept is normatively established in Article 19 of the CRPD and is presented as a legal fiction. The legal technique of fictio iuris is the premise for analyzing contemporary problems, for example, the attribution of responsibilities to non-human personalities, such as robots. The article, however, develops the problem of attributing rights to persons with disabilities. The (...) contraposition of robots and disabled people, understood as opposing visions of anthropological and human models, is part of the philosophical dispute between humanism and post- or transhumanism. The conception of man appears different if created in the image and likeness of God, or as the fruit of evolution from primates, or as a transhumanist entity that can be replaced by the robot. The latter vision is rooted in the mechanization of the mind triggered by cybernetics and cognitive sciences and referable to problems of justice theory and political philosophy concerning the inclusion in society of disabled people. In this article I will limit myself to analyzing, against the background of this complex problem, the link between person, legal fiction and the right to disability starting from the criticism addressed by Nussbaum to Rawls based on the convention and following the methodology developed by Marchisio and Curto in order to clarify the legal connection between thirdness, disability, and person.However, I go one step further by including the issue of disability as justice within the evolution of the notion of the legal person, through the inclusion of fictio iuris and rhetorical methodology in positive law, as a criterion for the interpretation of art. 19 CRPD.
