Rethinking Organismic Unity: Object-Oriented Ontology and the Human Microbiome

In recent years, a vast array of thinkers have been invested in challenging the long-standing binary division between the human and nonhuman. The notion of the human microbiome especially attests to the truth of such a complication, since current research in biology strongly suggests that we are at the very least as much microbe as we are human and that the number of microorganisms in the human body outnumber distinctly human cells considerably. In this article, we aim to bring the biological notion of the human microbiome in dialogue with Object-Oriented Ontology (OOO) so as to ultimately show that there can be a fruitful exchange of ideas between the two currents of microbiome research and OOO more specifically, and that Graham Harman's top-down account of objective emergence can be fruitfully a bottom-up approach according to which the parts of an object also impact and constrain the whole.
