All Shades of Passionfruit: Three Concepts of Universals and Truthmakers

Keywords: universals, concrete universals, truthmakers, monism, metaphysical grounding


The aim of this article is to compare the three concepts of universals presented in “Tropes and Universals” by Pawel Rojek with theories of truthmaking. Rojek presents three approaches to the problem of unity in multiplicity: (1) specific unity which involves abstract properties, (2) general unity based on undefined aspects, and (3) concrete universals. Rojek proposes to interpret the first two in scope of truthmaking, by invoking the “passionfruit argument” and developing his own version of it. In my paper I follow Rojek's steps by developing his comparison to truthmakers to the concept of concrete universals. That development involves Schaffer’s priority monism and the concept of “the most promiscuous truthmaker”. Finally, I present my own version of the “passionfruit argument” that uses the notion of grounding.
