Drawing on early modern French thought to free nature and aesthetics from metaphysical humanism What good is aesthetics in a time of ecological crisis? Toward a Premodern Posthumanism: Anarchic Ontologies of Earthly Life in Early Modern France shows that philosophical aesthetics contains unheeded potentialities for challenging the ontological subjection of nature to the human subject. Drawing on deconstructive, ecological, and biopolitical thought, Chad Córdova uncovers in aesthetics something irreducible to humanist metaphysics: an account of how beings emerge and are interrelated, responsive, and even response-able without reason or why. This anarchic and atelic ontology, recovered from Kant, becomes the guiding thread for a new, premodern trajectory of posthumanism. Charting a path from Aristotle to Heidegger to today's plant-thinking, with new readings of Montaigne, Pascal, Diderot, Rousseau, and others along the way, this capacious study reveals the untimely relevance of pre-1800 practices of writing, science, and art. Enacting a multitemporal mode of reading, Córdova offers a defense and illustration of the importance of returning to early modern texts as a way to rethink nature, art, ethics, and politics in a time when these concepts are in flux and more contentious than ever.
