According to the political philosopher Soumaya Mestiri, the state of exception caused by the outbreak of the CoVid-19 pandemic gives way to new conditions of solidarity: it shifts the “public sphere”, both as a matter of space and of political responsibility, towards that of the “common”. Referring to Giorgio Agamben, Michael Hardt, Antonio Negri and Judith Butler, she calls upon “a new common ‘contract’ that is fundamentally horizontal because it takes charge of naked life, first and foremost.” In times of CoVid-19, to produce “common”, or to “common” (communer), thus becomes a duty.
