In an article recently published in Italian, Bruno Latour explains that the new coronavirus illustrates in a striking way how non-human actors break into our collective spaces, demanding deep transformations (and inviting us to rethink ourselves within them). It is currently impossible to assess these changes over the long term. It is clear, however, that SARS-CoV-2 has had very visible effects on the institutions that shape our collective universe: financial markets, production chains, health systems, regulations, lockdowns. It seems to me that the place of convergence of these thematic areas is the body, a figure in which the medical, economic, social and media isotopies through which the virus circulates without disciplinary boundaries intersect. The thoughts that I entrust to this diary therefore go to the body, indeed, to the three dimensions of corporeality implied by the irruption of the virus in our collective. The first of these dimensions is the zoosemiotic one; the second is that of the discipline of individual bodies; the third is that of the biopolitical control of the collective body.
