    Peter Van Inwagen on material beings
    Ratio 15 (3). 2002.
    Peter van Inwagen's book Material Beings is centered on the special composition question: the question of when some simples constitute a complex object. Van Inwagen's answer to this question is that simples only constitute a complex object when they constitute an organism. I argue that van Inwagen's reasoning in favor of this conclusion is unconvincing, and also that the significance of the special composition question itself is doubtful

    Sider on existence
    Noûs 41 (3). 2007.
    In (2001), (2003), and elsewhere, Ted Sider presents two arguments concerning the existential quantifier which are justly central to the recent discussion of metaontology. What we will call Sider's indeterminacy argument is an attempted reductio of the suggestion that the existential quantifier might be semantically indeterminate. What we will call Sider's naturalness argument is an argument for the claim that the semantic value of the existential quantifier is the most eligible existence-like m…Read more

    Saving the Differences (review)
    Philosophical Review 113 (2): 288-292. 2004.
    The basic elements of this framework were elaborated upon and defended at some length in Wright’s Truth and Objectivity —henceforth, T&O—which was a marvelous book. The present volume of essays, almost all previously published and including some that predate T&O, continues to discuss the same themes, and is, in virtue of the significance of the ideas discussed and the high level of the discussion, likewise a very important work. The collection is divided into five parts: Realism Reconfigured, Re…Read more

    Carnap and ontological pluralism
    In David Chalmers, David Manley & Ryan Wasserman (eds.), Metametaphysics: New Essays on the Foundations of Ontology, Oxford University Press. pp. 130--56. 2009.
    My focus here will be Rudolf Carnap’s views on ontology, as these are presented in the seminal “Empiricism, Semantics and Ontology” (1950). I will first describe how I think Carnap’s distinction between external and internal questions is best understood. Then I will turn to broader issues regarding Carnap’s views on ontology. With certain reservations, I will ascribe to Carnap an ontological pluralist position roughly similar to the positions of Eli Hirsch and the later Hilary Putnam. Then I tur…Read more

    Metaphysical Vagueness and Metaphysical Indeterminacy
    Metaphysica 14 (2): 165-179. 2013.
    The topic of this paper is whether there is metaphysical vagueness. It is shown that it is important to distinguish between the general phenomenon of indeterminacy and the more narrow phenomenon of vagueness (the phenomenon that paradigmatically rears its head in sorites reasoning). Relatedly, it is important to distinguish between metaphysical indeterminacy and metaphysical vagueness. One can wish to allow metaphysical indeterminacy but rule out metaphysical vagueness. As is discussed in the pa…Read more

    What are Thick Concepts?
    Canadian Journal of Philosophy 41 (1): 25-49. 2011.
    Many theorists hold that there is, among value concepts, a fundamental distinction between thin ones and thick ones. Among thin ones are concepts like good and right. Among concepts that have been regarded as thick are discretion, caution, enterprise, industry, assiduity, frugality, economy, good sense, prudence, discernment, treachery, promise, brutality, courage, coward, lie, gratitude, lewd, perverted, rude, glorious, graceful, exploited, and, of course, many others. Roughly speaking, thick c…Read more

    Trends and Progress in Philosophy
    Metaphilosophy 44 (3): 276-292. 2013.
    This article is in three parts. The first discusses trends in philosophy. The second defends reliance on intuitions in philosophy from some doubts that have recently been raised. The third discusses Philip Kitcher's contention that contemporary analytic philosophy does not have its priorities straight. While the three parts are independent, there is a common theme. Each part defends what is regarded as orthodoxy from attacks. Of course there are other reasonable challenges to philosophical metho…Read more
