    You ought to save a larger group of people rather than a distinct smaller group of people, all else equal. A consequentialist may say that you ought to do so because this produces the most good. If a non-consequentialist rejects this explanation, what alternative can he or she give? This essay defends the following explanation, as a solution to the so-called numbers problem. Its two parts can be roughly summarised as follows. First, you are morally required to want the survival of each stranger …Read more

    Altruism and Ambition in the Dynamic Moral Life
    Australasian Journal of Philosophy 95 (4): 716-729. 2017.
    Some people are such impressive altruists that they seem to us to already be doing more than enough. And yet they see themselves as compelled to do even more. Can our view be reconciled with theirs? Can a moderate view of beneficence's demands be made consistent with a requirement to be ambitiously altruistic? I argue that a reconciliation is possible if we adopt a dynamic view of beneficence, which addresses the pattern that our altruism is required to take over time. This frees up theoretical …Read more

    Fickle consent
    Philosophical Studies 167 (1): 25-40. 2014.
    Why is consent revocable? In other words, why must we respect someone's present dissent at the expense of her past consent? This essay argues against act-based explanations and in favor of a rule-based explanation. A rule prioritizing present consent will serve our interests the best, in light of our interests in having flexibility over our consent and in minimizing the possibility of error in people's judgments about whether we consent.

    On Whether To Prefer Pain to Pass
    Ethics 121 (3): 521-537. 2011.
    Most of us are “time-biased” in preferring pains to be past rather than future and pleasures to be future rather than past. However, it turns out that if you are risk averse and time-biased, then you can be turned into a “pain pump”—in order to insure yourself against misfortune, you will take a series of pills which leaves you with more pain and better off in no respect. Since this vulnerability seems rationally impermissible, while time-bias and risk aversion seem rationally permissible, we ar…Read more

    The Burdens of Morality: Why Act‐Consequentialism Demands Too Little
    Thought: A Journal of Philosophy 5 (1): 82-85. 2016.
    A classic objection to act-consequentialism is that it is overdemanding: it requires agents to bear too many costs for the sake of promoting the impersonal good. I develop the complementary objection that act-consequentialism is underdemanding: it fails to acknowledge that agents have moral reasons to bear certain costs themselves, even when it would be impersonally better for others to bear these costs.

    Agent-neutral deontology
    Philosophical Studies 163 (2): 527-537. 2013.
    According to the “Textbook View,” there is an extensional dispute between consequentialists and deontologists, in virtue of the fact that only the latter defend “agent-relative” principles—principles that require an agent to have a special concern with making sure that she does not perform certain types of action. I argue that, contra the Textbook View, there are agent-neutral versions of deontology. I also argue that there need be no extensional disagreement between the deontologist and consequ…Read more
