Abstract

ABSTRACTThis paper examines the ontological status of individual substances; intuitive examples of such entities include particles and living organisms. My aim is to assess the ontological status of individual substances in the light of arguments for an ontology of [concrete] facts, often called states of affairs. Advocates of a fact ontology have argued that these factive entities are the ontologically fundamental beings. I will address the salient question of whether individual substances are reducible to, or eliminable in favor of, facts. I will further address the question of whether individual substances, even if not reducible to facts, are nonetheless ontologically dependent upon facts in a way that undercuts the claim that some individual substances are ontologically fundamental. Finally, I will argue that a persuasive case for the claim that facts are what is ontologically fundamental has yet to be made.
