Onnipotenza divina e ordine naturale nel Medioevo L’immutabilità del passato come garanzia del rispetto del corso della Natura

The present essay aims, on the one hand, to recall the reasons of anti-naturalism, intended in a metaphysical perspective, of a large part of medieval philosophical and theological reflection and, on the other hand, to show how the same type of problems, specifically those concerning the possible mutability or immutability of the past, can be employed in favour of various conflicting positions on the matter. To demonstrate this, reference was made to some thinkers who could represent emblematic positions on the theme, in particular: Pliny the Elder for the ancient world, Augustine of Hippo, Peter Damian, Bonaventure and Thomas Aquinas for the medieval era.
