Abstract
Diego de Deza has been designed by Christian Pesch as a premolinist while Friedrich Stegmüller has stressed the alleged disagreement between his version of Thomism and the one professed by later Spanish theologians. This paper aims to revisit this interpretation of Deza’s doctrine of divine foreknowledge by showing its fundamental agreement with Domingo Báñez, especially in placing the divine free will as an ingredient of divine knowledge of created things. Moreover, Deza’s teaching about divine grace brings him quite close to a Bañezian idea of premotion insofar as he supposes a special divine aid for every morally good act.
