Una finzione feconda per la filosofia della natura: Francisco Suarez e l’annihilatio mundi

This contribution focus on the fiction of the suppression of bodies by God (annihilatio mundi) and its implications for the philosophy of nature, namely within the development of the concepts of place and space. Recalling how some medieval thinkers formulate such an hypothesis, this study proposes a first analysis of its treatment by Francisco Suarez (in particular in the treatise De angelis). Indeed, in the wake of scholastic reflexions arisen in the XIIIth and XIVth centuries, Francisco Suarez made an abundant use of the fiction of the annihilatio mundi to support his thesis of the independence of spa-tial relationships with regard to the presence or absence of bodies, thus making the idea of emptiness (vacuum) philosophically plausible. This hypothetical treatment of the annihilatio mundi ultimately leads to a significant theoretical move beyond the Aristotelian conception of place.
