Toleration of What Is above Reason: The Impact of Leibniz’s View on Religious Belief on Experiential Matters

Abstract

The aim of this paper is to show how the understanding of Leibniz’s notion of toleration in matters of faith should be considered not merely as a pragmatic, but also as an epistemologically and metaphysically relevant concept. Following Maria Rosa Antognazza’s account, I will argue that Leibniz’s view on the belief of mysteries is ‘above reason’ and the relation between faith and experience plays an important role in his discussion of transubstantiation with Des Bosses, but also that Leibniz allows for presumptions based on faith to enter metaphysical discussions. Doing so, despite the fact that we cannot achieve certainty in these matters and have to accept a variety of different beliefs regarding the same objects, enriches our understanding of the world and of God—and also gives us reason to take seriously Leibniz’s engagement with corporeal substances, albeit only as presumptions rather than as necessary consequences of his basic metaphysical system. Finally, I will illustrate this point by showing how it is also in play in Leibniz’s response to Tournemine regarding the mind-body-union.
