The division between people and things is the postulate that seems to have organized from time immemorial the human experience. No other principle is so rooted in perception and moral conscience as the conviction that human beings are not things, because things, according to an insurmountable dichotomy, are the opposite of people. However, genealogical reconstruction, by uncovering the "device of the person", allows us to follow the divisive consequences that have shaped the modern horizon according to a double process of depersonalization (or reification) of the people and of desreificación (or anonadación) of the things. This knot between people and things, a determinant for the confluence of Roman law, Greek philosophy and Christian conception, can only be unraveled, according to Roberto Esposito, from the perspective of the body, third excluded from the dichotomy between things and people. What anthropological studies reveal about the body as a place of interaction between people and things in primitive societies resurfaces in a unique way in the contemporary experience with biotechnological objects that incorporate a subjective life. But in the current biopolitical regime, it is above all the body politic that, unrelated to the dichotomies of the modern political order, acquires an unusual role that demands a radical renewal of the vocabularies of politics, law and philosophy. In the conversation prepared for this edition, "Between Roman Law and the Society of the Spectacle", the author comments on some of the themes implicit in his book, such as the link between law and violence, the question of "the animal" or the problem Of political representation.
