Abstract

Many have written about trope ontology, but relatively few have considered its implications for some of the ontological conditions needed for us to have knowledge. I explore the resources of trope ontology to meet those conditions. With J. P. Moreland, I argue that, being simple, we can eliminate tropes’ qualitative contents without ontological loss, resulting in bare individuators. Then I extend Moreland’s argument, arguing that tropes undermine some of the needed ontological conditions for knowledge. Yet, we do know many things, and trope nominalists presuppose that too. Therefore, I consider three counter-arguments, starting with David Lewis’s rebuttal based on appeal to brute facts. Second, I explore Jeffrey Brower’s recent proposal as a possible solution. Last, I consider Robert Garcia’s recent distinction between module and modifier tropes, to see if it can be of assistance. I conclude, however, that trope nominalism cannot preserve some of the needed ontology to have knowledge.
