'Non minus vere homo aegrotus creatura Dei est quam sanus'. Pathological and the monstrous in Descartes' Sixth Meditation

In this essay, I address Descartes' medical thought, starting from the years of Le Monde and focus- ing especially on the "ontological" explanation of the dropsy in the Sixth Meditation. I especially consider Descartes' attempt to 'reform' physiology according to the universal methodology of geometrical reasoning, as well as with the importance given by Descartes' epistemology to the re- lationship between medicine and the mind-body union. The possibility of a coherent explanation of all the embodied phenomena, including illness and passions is, in fact, a strategic opportunity to show the existence of an inner regularity in God's Creation and so, to reconnect any 'practical' order (including medicine) to His essence. This leads Descartes to implicitly face the problem of the monstrous births, retracing what he could find in Toledo's and Conimbricenses' Commentaria.
