    I’m not sure how much knowledge everyone already has, so I’d like to start with a little questionnaire. On a card, say for each of the following topics whether you’re familiar with the topic, have heard of it but aren’t familiar with it, or have never heard of it

    Most people who believe in temporal parts believe that the referents of our ordinary referring terms, like Bill Clinton, or that table, are fusions of temporal parts from past, present and future times. Call these fusions worms, and the theory that the referents of ordinary referring terms (ordinary objects) the worm theory. Buying the metaphysical theory of temporal parts does not immediately imply that we must buy the worm theory. Theodore Sider (1996, 2000), for example, has suggested that th…Read more

    Misleading indexicals
    Analysis 62 (4). 2002.
    In “Now the French are invading England” (Analysis 62, 2002, pp. 34-41), Komarine Romdenh-Romluc offers a new theory of the relationship between recorded indexicals and their content. Romdenh-Romluc’s proposes that Kaplan’s basic idea, that reference is determined by applying a rule to a context, is correct, but we have to be careful about what the context is, since it is not always the context of utterance. A few well known examples illustrate this. The “here” and “now” in “I am not here now” o…Read more

    Ernest Adams has claimed that a probabilistic account of validity gives the best account of our intuitive judgements about the validity of arguments. In particular, he claims, it has the best hope of accounting for our judgements about many arguments involving conditionals. Most of the examples in the literature on this topic have been arguments framed in the language of propositional logic. I show that once we consider arguments involving predicates and involving identity, Adams’s strategy is l…Read more

    Three recent books have argued that Keynes’s philosophy, like Wittgenstein’s, underwent a radical foundational shift. It is argued that Keynes, like Wittgenstein, moved from an atomic Cartesian individualism to a more conventionalist, intersubjective philosophy. It is sometimes argued this was caused by Wittgenstein’s concurrent conversion. Further, it is argued that recognising this shift is important for understanding Keynes’s later economics. In this paper I argue that the evidence adduced fo…Read more

    The asymmetric magnets problem
    Philosophical Perspectives 20 (1). 2006.
    There are many controversial theses about intrinsicness and duplication. The first aim of this paper is to introduce a puzzle that shows that two of the uncontroversial sounding ones can’t both be true. The second aim is to suggest that the best way out of the puzzle requires sharpening some distinctions that are too frequently blurred, and adopting a fairly radical reconception of the ways things are.

    In Defence of the ACA's Medicaid Expansion
    Public Affairs Quarterly 27 (3): 267-288. 2013.
    The only part of the Patient Protection and Affordable Care Act (hereafter, ‘the ACA’) struck down in National Federation of Independent Business (NFIB) et al. v. Sebelius, Secretary of Health and Human Services, et al. was a provision expanding Medicaid. We will argue that this was a mistake; the provision should not have been struck down. We’ll do this by identifying a test that C.J. Roberts used to justify his view that this provision was unconstitutional. We’ll defend that test against some …Read more

    In earlier work I argued that using ‘vague probabilities’ did not ground any argument for significantly adjusting Bayesian decision theory. In this note I show that my earlier arguments don’t carry across smoothly to game theory. Allowing agents to have vague probabilities over possible outcomes dramatically increases the range of possible Nash equilibria in certain games, and hence arguably (but only arguably) increases the range of possible rational action.

    Barrett and Artzenius posed a problem concerning infinite sequences of decisions. It appeared that the strategy of making the rational choice at each stage of the game was, in some circumstances, guaranteed to lead to lower returns than the strategy of making the irrational choice at each stage. This paper shows that there is only the appearance of paradox. The choices that Barrett and Artzenius were calling ‘rational’ cannot be economically justified, and so it is not surprising that someone wh…Read more
