What is the relation of risk to negativity? Is it possible to think a notion of the negative that doesn't exclude the other via inclusion? These two questions are at the heart of Massimo Donà's discussion of immunity. Drawing on Roberto Esposito's genealogy of immunity in community, Donà shows how immunity depends upon a paradox of separation that brings the common and the immune closer together. After sketching the relation of immunity to the notion of polemos, Donà argues that the (...) immune subject, by including the other, negates itself so that the other becomes the true self. The essay closes with a series of reflections on how to think negation and immunity together through pregnancy; a negation that affirms a nonsubstitutive or alternative way of being. (shrink)
