Abstract
This article, from the viewpoint of the philosophy of Roberto Esposito, seeks to address the issue of why the birth of modernity in terms of a politics of life always threatens to become a politics of death. I defend the thesis that the experience of death in contemporary politics is the consequence of a paradigm of immunization. The careful analysis of this thesis will show that the biopolitical mechanism formulated by Foucault (with whom I am in agreement), without doubt, explains why the dangers of this form of biopower to be immunized are deeply rooted in our thinking in modernity.
