    Desires
    Mind 117 (466): 267-302. 2008.
    We argue that desire is an attitude that relates a person not to one proposition but rather to two, the first of which we call the object of the desire and the second of which we call the condition of the desire. This view of desire is initially motivated by puzzles about conditional desires. It is not at all obvious how best to draw the distinction between conditional and unconditional desires. In this paper we examine extant attempts to analyse conditional desire. From the failures of those …Read more

    A Moorean View of the Value of Lives
    Pacific Philosophical Quarterly 95 (4): 23-46. 2014.
    Can we understand being valuable for in terms of being valuable? Three different kinds of puzzle cases suggest that the answer is negative. In what follows, I articulate a positive answer to this question, carefully present the three puzzle cases, and then explain how a friend of the positive answer can successfully respond to them. This response requires us to distinguish different kinds of value bearers, rather than different kinds of value, and to hold that among the value bearers are totalit…Read more

    Modal realisms
    Philosophical Perspectives 20 (1). 2006.
    Possibilism—the view that there are non-actual, merely possible entities—is a surprisingly resilient doctrine.1 One particularly hardy strand of possibilism—the modal realism championed by David Lewis—continues to attract both foes who seek to demonstrate its falsity (or at least stare its advocates into apostasy) and friends who hope to defend modal realism (or, when necessary, modify modal realism so as to avoid problematic objections).2 Although I am neither a foe nor friend of modal realism …Read more

    Extended simples
    Philosophical Studies 133 (1). 2007.
    I argue that extended simples are possible. The argument given here parallels an argument given elsewhere for the claim that the shape properties of material objects are extrinsic, not intrinsic as is commonly supposed. In the final section of the paper, I show that if the shape properties of material objects are extrinsic, the most popular argument against extended simples fails.

    Brutal Simples
    In Dean W. Zimmerman (ed.), Oxford Studies in Metaphysics, Oxford University Press. pp. 233. 2008.
    I argue that there are is no informative statement of necessary and sufficient conditions for being a mereological simple.

    From the perspective of a contemporary metaphysician, Metaphysical Themes 1274–1671 is a fantastic book. It is an impressively rich, detailed, and thorough examination of a multitude of important metaphysical puzzles and arguments, written in a clear, engaging, lively, funny, and even on one occasion vulgar manner. The number of topics covered is astonishing: substance, attribute, form, matter, the metaphysics of predication, parts and wholes, the metaphysics of extension across space, persisten…Read more
