    Liberalism and mental mediation
    Journal of Value Inquiry 38 (2): 186-202. 2004.
    Liberals agree that free speech should be protected, where speech is understood broadly to include all forms of intentional communication, including actions and pictures, not merely the spoken or written word. A surprising view about free speech in some liberal and legal circles is that communications should be protected on free-speech grounds only if the communications are mentally mediated. By “mentally mediated communication” we mean speech which communicates its message in such a way that th…Read more

    Reflexive fictionalisms
    Analysis 56 (1): 23-32. 1996.
    There is a class of fictionalist strategies (the reflexive fictionalisms) which appear to suffer from a common problem: the problem that the entities which are supposedly fictional turn out, by the lights of the fictionalist theory itself, to exist. The appropriate solution is to reject so-called strong fictionalism in each case: that is, to reject the variety of fictionalism which takes appeal to the domain of fictional entities to provide an explanation or analysis of the operators or predi…Read more

    Possible Worlds Semantics
    In Gillian Russell & Delia Fara (eds.), The Routledge Companion to Philosophy of Language, Routledge Press. pp. 242-252. 2012.
    This chapter provides an introduction to possible worlds semantics in both logic and the philosophy of language, including a discussion of some of the advantages and challenges for possible worlds semantics.

    Recombination unbound
    Philosophical Studies 84 (2-3): 239-262. 1996.
    This paper discusses the principle of recombination for possible worlds. It argues that arguments against unrestricted recombination offered by Forrest and Armstrong and by David Lewis fail, but a related argument is a challenge, and recommends that we accept an unrestricted principle of recombination and the conclusion that possible worlds form a proper class

    Canberra Plan
    A Companion to Philosophy in Australia and New Zealand. 2010.
    This encylopedia entry describes the "Canberra Plan" approach to conceptual analysis, a method closely related to the Ramsey-Carnap-Lewis approach to analysing the meaning of theoretical terms.

    Lewis's Philosophical Method
    In B. Loewer & J. Schaffer (eds.), A Companion to Lewis, Wiley-blackwell. pp. 25-39. 2015.
    Lewis is famous as a contemporary philosophical system-builder. The most obvious way his philosophy exhibited a system was in its content: Lewis’s metaphysics, for example, provided answers to many metaphysical puzzles in an integrated way, and there are illuminating connections to be drawn between his general metaphysical views and, for example, his various views about the mind and its place in nature

    Impossible Worlds
    Philosophy Compass 8 (4): 360-372. 2013.
    Philosophers have found postulating possible worlds to be very useful in a number of areas, including philosophy of language and mind, logic, and metaphysics. Impossible worlds are a natural extension to this use of possible worlds, and can help resolve a number of difficulties thrown up by possible‐worlds frameworks.

    Methodological Naturalism in Metaethics
    In Tristram Colin McPherson & David Plunkett (eds.), The Routledge Handbook of Metaethics, Routledge. pp. 659-673. 2017.
    Methodological naturalism arises as a topic in metaethics in two ways. One is the issue of whether we should be methodological naturalists when doing our moral theorising, and another is whether we should take a naturalistic approach to metaethics itself. Interestingly, these can come apart, and some naturalist programs in metaethics justify a non-scientific approach to our moral theorising. This paper discusses the range of approaches that fall under the general umbrella of methodological natur…Read more

    Selfless Desires
    Philosophy and Phenomenological Research 73 (3): 665-679. 2007.
    Unified theories of de se attitudes and de dicto attitudes, along the lines of David Lewis’s proposal, face a problem. Whether or not they are adequate for representing beliefs, they can misrepresent the content of many of our desires, which rank possible outcomes in which the agent with the desire does not exist. These desires are shown to play a role in the rational explanation of action, and recognising them is important in our understanding of ourselves. Lewis’s account of attitudes de di…Read more

    Balls and All
    In S. Kleinschmidt (ed.), Mereology and Location, Oxford University Press. pp. 91-116. 2014.
    This paper describes a plausible view of the nature of physical objects, their mereological connections to each other, and their relation to spacetime. As well as being parsimonious, the view provides a plausible context for denying all of the following: (1) A theory that objects endure through time (and do not have temporal parts, as normally conceived) cannot claim that material objects are identical to space-time regions they occupy. (2) At least one of the family of mereological connecti…Read more

    Hyperintensional metaphysics
    Philosophical Studies 171 (1): 149-160. 2014.
    In the last few decades of the twentieth century there was a revolution in metaphysics: the intensional revolution. Many metaphysicians rejected the doctrine, associated with Quine and Davidson, that extensional analyses and theoretical resources were the only acceptable ones. Metaphysicians embraced tools like modal and counterfactual analyses, claims of modal and counterfactual dependence, and entities such as possible worlds and intensionally individuated properties and relations. The twenty-…Read more

    The question of moral ontology
    Philosophical Perspectives 28 (1): 201-221. 2014.
    Our ordinary moral practices not only suppose that some people ought to perform some actions, and that some outcomes are morally better or worse than others, but also that there are rights, duties, goodness, and other apparently abstract moral entities. What should we make of these entities, and the talk of these entities? It is not straighforward to account for these entities in other terms. On the other hand, this paper will argue that talk of such entities is not easily eliminated from goo…Read more

    The A Posteriori Armchair
    Australasian Journal of Philosophy 93 (2): 211-231. 2015.
    A lot of good philosophy is done in the armchair, but is nevertheless a posteriori. This paper clarifies and then defends that claim. Among the a posteriori activities done in the armchair are assembling and evaluating commonplaces; formulating theoretical alternatives; and integrating well-known past a posteriori discoveries. The activity that receives the most discussion, however, is the application of theoretical virtues to choose philosophical theories: the paper argues that much of this is …Read more

    Liar-like paradox and object language features
    American Philosophical Quarterly 45 (1). 2008.
    We argue that it would seem to be a mistake to blame Liar-like paradox on certain features of the object language, since the effect can be created with very minimal object languages that contain none of the usual suspects (truth-like predicates, reference to their own truth-bearers, negation, etc.).

    Personification and Impossible Fictions
    British Journal of Aesthetics 55 (1): 57-69. 2015.
    Impossible fictions are not just the creations of puzzle-seeking philosophers or artists experimenting with the limits of fiction. Impossibilities can be found in relatively mundane fiction as well. This article argues that the device of personification, especially of abstract entities such as death or duty, yields impossible fictions, arguing against a number of strategies that might be tried to show that these cases of personification do not yield impossibilities.

    Cosmic Loops
    In Ricki Bliss & Graham Priest (eds.), Reality and its Structure: Essays in Fundamentality, Oxford University Press. pp. 91-106. 2018.
    This paper explores a special kind of loop of grounding: cosmic loops. A cosmic loop is a loop that intuitively requires us to go "around" the entire universe to come back to the original ground. After describing several kinds of cosmic loop scenarios, I will discuss what we can learn from these scenarios about constraints on grounding; the conceivability of cosmic loops; the possibility of cosmic loops; and the prospects for salvaging local reflexivity, asymmetry and transitivity of grounding…Read more

    Epistemic Dispositions: Reply to Turri and Bronner
    Logos and Episteme 3 (4): 629-636. 2012.
    We reply to recent papers by John Turri and Ben Bronner, who criticise the dispositionalised Nozickian tracking account we discuss in “Mad, Bad and Dangerous to Know.” We argue that the account we suggested can handle the problems raised by Turri and Bronner. In the course of responding to Turri and Bronner’s objections, we draw three general lessons for theories of epistemic dispositions: that epistemic dispositions are to some extent extrinsic, that epistemic dispositions can have manifestatio…Read more

    Fictionalist Attitudes about Fictional Matters
    In Mark Eli Kalderon (ed.), Fictionalism in Metaphysics, Clarendon Press. pp. 204-233. 2005.
    A pressing problem for many non-realist1 theories concerning various specific subject matters is the challenge of making sense of our ordinary propositional attitude claims related to the subject in question. Famously in the case of ethics, to take one example, we have in ordinary language prima facie ascriptions of beliefs and desires involving moral properties and relationships. In the case, for instance, of “Jason believes that Kylie is virtuous”, we appear to have a belief which takes Kylie …Read more

    Consequentialism and Side Constraints
    Journal of Moral Philosophy 6 (1): 5-22. 2009.
    Many people are inclined to think that consequences of actions, or perhaps reasonably expected consequences of those actions, have moral weight. Firing off shotguns in crowded areas is typically wrong, at least in part, because of the people who get maimed and killed. Committed consequentialists think that consequences (either actual consequences, or expected consequences, or intended consequences, or reasonably expected consequences, or maybe some other different shade) are all that matters, mo…Read more

    Reality and Humean Supervenience: Essays on the Philosophy of David Lewis (review)
    Philosophical Review 112 (2): 263-266. 2003.
    David Lewis’s work in the past few decades produced a powerful and thought-provoking system, and this collection of eleven essays represents state-of-the-art engagement with that system across a range of topics. The title would suggest that the papers would deal in particular with Lewis’s doctrine of Humean supervenience, the doctrine that all the contingent truths are ultimately determined by instantiations of fundamental categorical properties at points of space-time, and the spatiotemporal re…Read more

    As is well known, Aristotelian natural philosophy, and many other systems of natural philosophy since, have relied heavily on teleology and teleological causation. Somehow, the purpose or end of an obj ect can be used to predict and explain what that object does: once you know that the end of an acorn is to become an oak, and a few things about what sorts of circumstances are conducive to the attainment of this end, you can predict a lot about the sprouting of the acorn and the subsequent behavi…Read more

    Method in Analytic Metaphysics
    In Herman Cappelen, Tamar Gendler & John P. Hawthorne (eds.), The Oxford Handbook of Philosophical Methodology, Oxford University Press. 2016.
    This article focuses on the main methods used in analytic metaphysics. It first considers five important sources of constraints on metaphysical theorizing: linguistic and conceptual analysis, consulting intuitions, employing the findings of science, respecting folk opinion, and applying theoretical virtues in metaphysical theory choice such as preferring simpler theories, or preferring more explanatory theories. It then examines the role of formal methods in metaphysics as well as the role of me…Read more

    Conditionals and Curry
    Philosophical Studies 173 (10): 2629-2647. 2016.
    Curry's paradox for "if.. then.." concerns the paradoxical features of sentences of the form "If this very sentence is true, then 2+2=5". Standard inference principles lead us to the conclusion that such conditionals have true consequents: so, for example, 2+2=5 after all. There has been a lot of technical work done on formal options for blocking Curry paradoxes while only compromising a little on the various central principles of logic and meaning that are under threat. Once we have a sense o…Read more
