Fede, ragione e il principio di non-contraddizione in Pier Damiani

In literature Peter Damian has been often presented as an anti-dialectic thinker. Over time this statement has been subjected to careful historiographical revision. Today it is commonly accepted that the distinction between dialectic and anti-dialectic thinkers only partially describes the state of philosophy in the eleventh century. In fact, the relation between faith and reason is complex in Damian. The purpose of this paper is to reconsider this relation in the light of the significance Damian attributes to the notion of contradiction. Reason must respect the principle of non-contradiction not only when it describes the natural world, but also when it explores the dimension of the mysteries of faith.
