What is the so-called “question of ontology?” Is the question of ontology genuinely a question about “categories” (Lowe 2006), “structure” (Sider 2011), “existence” (Thomasson 2015), or rather “reality” (Fine 2009)? In this article, I defend the neo-Sellarsian approach to the question of ontology, a novel, naturalistic approach according to which the foundational question of ontology is about “understanding the manifest and the scientific images of the world, and their multiple relationships.” First, I argue for the thesis of Impure Eliminativism, a (...) form of constructive pluralism about the question of ontology by which the substantivity of questions of ontology which are not the neo-Sellarsian one is to be built upon certain relations with the neo-Sellarsian question of ontology. Second, I argue for the categorial plasticity of the two images and their relations in connection with the hypothesis of Weak Epistemic Factualism. Third, and lastly, I argue for a person-based ontology framed in terms of the crucial notions of “fact” and “understanding” in response to the eliminativist categorizations of the two images and their relationships proposed by substantialism and structuralism.
