    This paper does four things. First it lays out an orthodox position on reasons and defeaters. Then it argues that the position just laid out is mistaken about “undercutting” defeaters. Then the paper explains an unpublished thought experiment by Dorothy Edgington. And then it uses that thought experiment to motivate a new approach to undercutting defeaters.

    Physicalism and overdetermination
    Mind 107 (426): 411-432. 1998.
    I argue that our knowledge of the world's causal structure does not generate a sound argument for physicalism. This undermines the popular view that physicalism is the only scientifically respectable worldview

    Stalnaker on sensuous knowledge
    Philosophical Studies 137 (2). 2008.
    Robert Stalnaker has recently argued that a pair of natural thoughts are incompatible. One of them is the view that items of non-indexical factual knowledge rule out possibilities. The other is the view that knowing what sensuous experience is like involves non-indexical knowledge of its phenomenal character. I argue against Stalnaker’s take on things, elucidating along the way how our knowledge of what experience is like fits together with the natural idea that items of non-indexical factual kn…Read more

    Apriorism about Modality
    In Bob Hale & Aviv Hoffmann (eds.), Modality: metaphysics, logic, and epistemology, Oxford University Press. pp. 275-318. 2010.
    This chapter argues that a priori reflection is at best a fallible guide to modality (both possibility and necessity). It also claims that the usefulness of a priori reflection, as a guide to possibility and necessity, turns on the ‘bounty’ of modality itself. If possibility turns out to be plentiful — in a sense glossed in the chapter — it is argued that a priori reflection will be a good-but-fallible guide to it. If necessity turns out to be meagre — in a dual sense of that gloss — it is argue…Read more

    Humean chance: Five questions for David Lewis (review)
    Erkenntnis 49 (3): 321-335. 1998.
    David Lewis's approach to objective chance is doubly distinctive. On the one hand, Lewis uses an epistemic principle to disclose the nature of chance. One the other, Lewis conjoins realism about chance with a reductive Humean metaphysics. I aim to undermine both aspects of his view. Specifically, I argue that reductive Humeanism fails across the board, and I use my discussion of chance to explain why. I also argue Lewis's "best-systems" approach to chance fails his own criteria for a metaphysics…Read more

    Conditional Belief and the Ramsey Test
    Royal Institute of Philosophy Supplement 51 215-232. 2002.
    Consider the frame S believes that—. Fill it with a conditional, say If you eat an Apple, you'll drink a Coke. what makes the result true? More generally, what facts are marked by instances of S believes ? In a sense the answer is obious: beliefs are so marked. Yet that bromide leads directly to competing schools of thought. And the reason is simple. Common-sense thinks of belief two ways. Sometimes it sees it as a three-part affair. When so viewed either you believe, disbelieve, or suspend judg…Read more
