In Por una repolitización del mundo. Las vidas descartables como desafío del siglo xxi (Siglo Veintiuno Editores, 2018), Didier Fassin, James D. Wolfensohn Professor in the School of Social Science, examines who today has the right to a decent existence and how public authorities trace the boundary between those who are saved and those who are condemned to expulsion. The field work carried out in three continents over the last thirty years allows him to demonstrate how, more and more, inequalities are inscribed in the bodies of people in terms of suffering, the acts of violence are reinterpreted in the lexicon of trauma, and the request for social justice becomes a call to compassion.
