    Recalibrating evolutionary debunking
    Philosophy and Phenomenological Research. forthcoming.
    Evolutionary debunking arguments purport to show that, if moral realism is true, all of our moral beliefs are unjustified. In this paper, I respond to two of the most enduring objections that have been raised against these arguments. The first objection claims that evolutionary debunking arguments are self-undermining, because they cannot be formulated without invoking epistemic principles, and epistemic principles are just as vulnerable to debunking as our moral beliefs. I argue that this objec…Read more

    Higher-Order Evidence and Human Evolution
    Dissertation, University of Massachusetts, Amherst. 2022.
    Suppose that Sherlock Holmes has just closed another case, and is convinced that Moriarty is the perpetrator. At that very moment, Inspector Lestrade arrives to inform Holmes that a Scotland Yard analysis of his past investigations shows that he only identifies the correct suspect in 50% of cases. How should Holmes respond to this new information? This is a question about higher-order evidence. Higher-order evidence can be understood as evidence about the rationality of your beliefs, or about yo…Read more

    The medical model, with a human face
    Philosophical Studies 179 (12): 3747-3770. 2022.
    In this paper, I defend a version of the medical model of disability, which defines disability as an enduring biological dysfunction that causes its bearer a significant degree of impairment. We should accept the medical model, I argue, because it succeeds in capturing our judgments about what conditions do and do not qualify as disabilities, because it offers a compelling explanation for what makes a condition count as a disability, and because it justifies why the federal government should spe…Read more

    The epistemology of evolutionary debunking
    Synthese 199 (5-6): 12155-12176. 2021.
    Fifteen years ago, Sharon Street and Richard Joyce advanced evolutionary debunking arguments against moral realism, which purported to show that the evolutionary history of our moral beliefs makes moral realism untenable. These arguments have since given rise to a flurry of objections; the epistemic principles Street and Joyce relied upon, in particular, have come in for a number of serious challenges. My goal in this paper is to develop a new account of evolutionary debunking which avoids the p…Read more

    Options must be external
    Philosophical Studies 177 (5): 1175-1189. 2020.
    Brian Hedden has proposed that any successful account of options for the subjective “ought” must satisfy two constraints: first, it must ensure that we are able to carry out each of the options available to us, and second, it should guarantee that the set of options available to us supervenes on our mental states. In this paper I show that, due to the ever-present possibility of Frankfurt-style cases, these two constraints jointly entail that no agent has any options at any time. This consequenc…Read more
