    1000 time-travelers travel back in time, each with the intention of killing their own infant-self. If there is no branching time, then on pain of bringing about a logical contradiction, all must fail. But this seems inexplicable: what is to ensure that the time-travelers are stopped? For a time, this inexplicability objection was thought to provide evidence that there is something incoherent about the possibility of backwards time travel in a universe without branching time. There is now near-co…Read more

    Heim Sequences and Why Most Unqualified ‘Would’-Counterfactuals Are Not True
    Australasian Journal of Philosophy 99 (3): 597-610. 2021.
    ABSTRACT The apparent consistency of Sobel sequences famously motivated David Lewis to defend a variably strict conditional semantics for counterfactuals. If Sophie had gone to the parade, she would have seen Pedro. If Sophie had gone to the parade and had been stuck behind someone tall, she would not have seen Pedro. But if the order of the counterfactuals in a Sobel sequence is reversed—in the example, if is asserted prior to —the second counterfactual asserted no longer rings true. This is th…Read more

    Just as knowledge contextualism offers a way out of knowledge skepticism in the face of powerful skeptical arguments, counterfactual contextualism purports to answer the many compelling arguments for the skeptical thesis that most ordinary counterfactuals of the form ‘if A had happened, C would have happened’, are false. In this article I review a few of the arguments for counterfactual skepticism, before surveying the various types of contextualist responses. I then discuss some of the recent o…Read more

    Morgenbesser’s Coin
    Canadian Journal of Philosophy 51 (5): 317-328. 2021.
    Before a fair, indeterministic coin is tossed, Lucky, who is causally isolated from the coin-tossing mechanism, declines to bet on heads. The coin lands heads. The consensus is that the following counterfactual is true: (M:) If Lucky had bet heads, he would have won the bet. It is also widely believed that to rule (M) true, any plausible semantics for counterfactuals must invoke causal independence. But if that’s so, the hope of giving a reductive analysis of causation in terms of counterfactu…Read more

    Why the Direct Argument Does Not Shift the Burden of Proof
    Journal of Philosophy 113 (4): 210-223. 2016.
    Peter van Inwagen's influential Direct Argument (DA) for the incompatibility of moral responsibility and causal determinism makes use of an inference rule he calls "Rule B." Michael McKenna has argued that van Inwagen's defense of this rule is dialectically inappropriate because it is based entirely on alleged “confirming” cases that are not of the right kind to justify the use of Rule B in DA. Here I argue that McKenna’s objection is on the right track but more must be said if we are to see why…Read more

    Reasons‐responsiveness, control and the negligence puzzle
    Philosophical Issues 33 (1): 124-139. 2023.
    A longstanding puzzle about moral responsibility for negligence arises from three plausible yet jointly inconsistent theses: (i) an agent can, in certain circumstances, be morally responsible for some outcome O, even if her behavior with respect to O is negligent (i.e., even if she never adverted to the possibility that the behavior might result in O), (ii) an agent can be morally responsible for O only if she has some control over O, (iii) if an agent acts negligently with respect to O, then sh…Read more
