Abstract

In this paper, I present the way Duns Scotus’ philosophy is used in the contemporary discussions on properties. I point out that both realists about universals and trope theorists invoke Scotus to defend their positions. Moreover, I show that they do it by taking the same concept, formal distinction, to apply it to the same problem: the distinction between the qualitative and the individuating features of properties. After presenting the contemporary uses of Scotus, I turn to his own theory of natures and I ask to what extent he may be a realist about universals or a defender of the trope view. I do not provide a firm answer to this question, but I show that much depends on Scotus’ account of the formal distinction, and on his possible change of mind with respect to this notion.
