Toledan Ontologies: Gundissalinus, Ibn Daud, and the Problem of Gabirolian Hylomorphism

This contribution focuses on a particular branch of Gundissalinus’s production, namely ontology, and a peculiar feature of his reflection: the progressive problematization of his doctrine of hylomorphism. I will analyse the sources that influenced Gundissalinus’s mature discussion of ontological composition, underscoring the changes introduced by the Toledan philosopher to his previous doctrinal positions regarding the status of hylomorphic components and their cosmogonic causation. In order to do so, I will briefly examine the opposing theories elaborated by Ibn Gabirol and Ibn Sīnā, doctrines merged together by Gundissalinus in his final metaphysical reflection. Eventually, I will put forward a hypothesis about a possible medium of both Gundissalinus’s change of position and his doctrinal synthesis – i.e., Ibn Daud’s philosophical influence on Gundissalinus.
