Quine is routinely perceived as saving metaphysics from Carnapian positivism. Where Carnap rejects metaphysical existence claims as meaningless, Quine is taken to restore their intelligibility by dismantling the former’s internal–external distinction. The problem with this picture, however, is that it does not sit well with the fact that Quine, on many occasions, has argued that metaphysical existence claims ought to be dismissed. Setting aside the hypothesis that Quine’s metaphysical position is incoherent, one has to conclude that his views on metaphysics (...) are subtler than is often presupposed; both the received view that Quine saved metaphysics and the opposite view that Carnap and Quine are on the same anti-metaphysical team seem too one-sided if we take seriously Quine’s own pronouncements on the issue. In this paper, I offer a detailed reconstruction of Quine’s perspective on metaphysical existence claims. Scrutinizing his published work as well as unpublished papers, letters, and notebooks, I show how Quine is able to both blur the boundary between scientific sense and metaphysical nonsense and to argue that we cannot ask what reality is really like in a distinctively philosophical way. I argue that although Quine’s position is much closer to Carnap’s than the received view suggests, it still differs in two crucial respects. (shrink)

Early analytic philosophers like Carnap, Wittgenstein and Ryle regarded ontology as a branch of metaphysics that is either trivial or meaningless. But at present it is generally assumed that philosophy can make substantial discoveries about what kinds of things exist and about the essence of these kinds. My paper challenges this ontological turn. The currently predominant conceptions of the subject, at any rate, do not license the idea that ontology can provide distinctively philosophical insights into the constituents of reality. I (...) distinguish four main sources of analytic ontology—Strawson's descriptive metaphysics, Kripke's realist semantics, the Austro-Australian truth-maker principle, Quine's naturalistic conception of ontology—and indicate briefly why the first three do not rehabilitate ontology. In the remainder, I concentrate on the most influential and promising position. Quinean ontology seeks to bring out and reduce the ontological commitments of our best scientific theories through logical paraphrase. Against this programme, I argue that Quine's conception of ontological commitment is inadequate, and that his logical paraphrase cannot contribute to the exploration of reality, but at most to the clarification of our conceptual framework.

Disagreement over what exists is so fundamental that it tends to hinder or even to block dialogue among disputants. The various controversies between believers and atheists, or realists and nominalists, are only two kinds of examples. Interested in contributing to the intelligibility of the debate on ontology, in 1939 Willard van Orman Quine began a series of works which introduces the notion of ontological commitment and proposes an allegedly objective criterion to identify the exact conditions under which a theoretical discourse (...) signals an assumption of existence. I intend to present the concept of ontological commitment and the Quinean criterion, to expose and evaluate some of the many criticisms to which the criterion has subject and to situate it in the context of Quine’s philosophy. As a product of such analyses, I hope to contribute to the discussion on the application and relevance of the notion of ontological commitment. (shrink)
