"Holobionts and their epistemic status"
Résumé : There has been a lot of discussion recently about the ‘nature’ of holobionts (communities of microorganisms in all sorts of niches, including the human body, which will be my focus). I doubt this is a genuine metaphysical debate. I will show you how certain supposedly holistic notions of holobionts came about epistemically (as methodological artefacts). I will then show how strong community-level notions of holobionts are being undermined as mechanistic analyses come to the fore in this research field. Also undermined are accompanying claims about ‘dysbiosis’ and ‘homeostasis’. Finally, I will reflect on whether communities that do not function as physiological wholes could possibly function as evolutionary individuals.
