Abstract
The main aim of this paper is to propose an adequate interpretation of the concept esse ap-parens (apparent being) which was used by Franciscan philosopher and theologian Peter Auriol (c. 1280 – 1322), especially focusing on his account of sensory perception. Basing on the analysis of relevant passages of the commentary on the Sentences by Auriol, first, I introduce his famous account of sensory illusions, and then his own claims about nature of esse apparens (Auriol refuses both that it is separate entity serving as a mediator of perception, and that it is only extrinsic denomination of the perceived object). In the next part, I refuse the interpretation which esse apparens identifies with mental representation. In my opinion, it is more appropriate to engage this concept into the context of scholastic doctrine of objective or intentional being (popularized mainly by Duns Scotus and his disciples). In the end of the paper, I return to the Auriol’s account of illusions and show that it is compatible with esse apparens understood as mode of being.
