Gerard of Bologna and Hervaeus Natalis on the Intuition of Non-Existents

The following paper shows that prior to Ockham’s doctrine on the intuition of non-existents, two Parisian theologians (Gerard of Bologna, c. 1240/50-1317; Hervaeus Natalis, c. 1250/60-1323) had already developed, in opposition to Duns Scotus, their own theories on the possibility of having intuitive cognition of non-existent or absent things. The article uses the editions of the two theologians’ Quodlibeta prepared by the author.
