| Abstract: | This paper concerns a fundamental dispute in ontology between the " Foundational Ontologist ", who believes that there is only one correct way of characterizing what there is, and the ontological " Skeptic ", who believes that there are viable alternative characterizations of what there is. I examine in detail an intriguing recent proposal in Dorr (2005), which promises to yield (i) a way of interpreting the Skeptic by means of a counter/actual semantics; and (ii) a way of converting the Skeptic to a position within Foundational Ontology, viz., that of Nihilism (according to which nothing composes anything and the world consists of mereological simples); this alleged conversion crucially turns on a novel notion of " metaphysical analyticity ". I argue that both components of Dorr's proposal are problematic in central ways: as a result, the Foundational Ontologist gains an indirect argument against the coherence of the Skeptic's position; and the non-Nihilist Foundational Ontologist may feel confirmed in his doubts towards the Nihilist outlook. |
