The concept of instantiation is realized differently across a variety of metaphysical theories. A certain realization of the concept in a given theory depends on what roles are specified and associated with the concept and its corresponding term as well as what entities are suited to fill those roles. In this paper, the classic realization of the concept of instantiation in a one-category ontology of abstract particulars or tropes is articulated in a novel way and defended against unaddressed objections.

Trenton Merricks argues for and defends a novel version of primitivism about truth : being true is a primitive monadic but non-intrinsic property. This examination consists of the following triad: a critical discussion of Merricks’ argument for his view, a rejection of his objection against Paul Horwich’s minimalist theory of truth, and a direct objection against his view on the grounds that it entails being true is a mysterious and suspicious property. The conclusion is that Merricks’ primitivism should be rejected

David Lewis objected to theories that posit necessary connections between distinct entities and to theories that involve a magical grasping of their primitives. In On the Plurality of Worlds, Lewis objected to nondescript ersatzism on these grounds. The literature contains several reconstructions of Lewis’ critique of nondescript ersatzism but none of these interpretations adequately address his main argument because they fail to see that Lewis’ critique is based on broader methodological considerations. I argue that a closer look at his methodology reveals the broader objection he presented against nondescript ersatzism. This objection, I further argue, remains a challenge for the ersatzer who posits structure-less entities as possible worlds.
