The human stomach was said to be one of God’s greatest inventions, an oven for his earthly chemistry lab. The human ability to understand and manipulate individual chemical elements would always pale in comparison to the alchemy of digestion, which was designed with celestial complexity. In this model, digestion takes on expansive metaphysical dimensions that appear far removed from how we might conceive of digestion today. But digestion theories are fundamental representations of how one conceives of the threshold where the body meets the world. As such, any understanding of how the body digests is always in some way metaphysical, a product of models for how the body is more broadly situated in the world within a given cosmology.

While scientists search the human genome for DNA sequences that set us apart from other species, evidence suggests that we share much of our genetic identity with viruses. Rhizomorphic connections with other creatures, mediated by our viruses, may be happening all the time, along thousands of lines of flight. Infectious agents link humanity with other creatures who live with us in shared multispecies worlds. We are kin with our viral relations.

Survivance is dependent upon negotiating and being-with toxic relations as much as chosen and desired ones. Furthermore, discerning the toxicities from the nourishments within the very same relationship is a familiar task of anguish. This is the practice of being-with the kinships we do not choose—human and more-than-human. This is the practice of living inside of contradiction and contamination.

There are a lot of unknowns in human interactions with viruses, especially when we are facing a newly emerging virus. But the idea of viruses as “things” provides an overall strategy that promises to leave us mainly with known unknowns.
