The article aims to answer whether there are signs of St Bonaventure’s presence in Leibniz. St Bonaventure is best known in the seventeenth century for his theological and mystical imprint. For his part, Leibniz wrote a work entitled On True Mystical Theology. We will therefore situate mystical thought in the context of Leibniz to be able to reference this writing in the mystical context of Bonaventure’s inspiration and to be able to find, perhaps, an indirect trace of the thought of the Franciscan master. This, in turn will serve to contextualise Leibniz’s writing.
