    Moti Mizrahi provides experimental evidence according to which subjects judge that a person ought to ? even when she cannot ?. He takes his results to constitute a falsification of the alleged intuitiveness of the ‘Ought Implies Can’ principle. We point out that in the light of the fact that (a) ‘ought’ is multiply ambiguous, that (b) only a restricted set of readings of ‘ought’ will be relevant to the principle, and that (c) he did not instruct his subjects appropriately – or otherwise ensure …Read more

    Debate: Ideal Theory—A Reply to Valentini
    Journal of Political Philosophy 18 (3): 357-368. 2009.
    In her ‘On the apparent paradox of ideal theory’, Laura Valentini combines three supposedly plausible premises to derive the paradoxical result that ideal theory is both unable to, and indispensable for, guiding action. Her strategy is to undermine one of the three premises by arguing that there are good and bad kinds of ideal theory, and only the bad kinds are vulnerable to the strongest version of their opponents’ attack. By undermining one of the three premises she releases ideal theorists fr…Read more

    Climate Matters Pro Tanto, Does It Matter All-Things-Considered?
    Midwest Studies in Philosophy 40 (1): 129-142. 2016.
    In Climate Matters (2012), John Broome argues that individuals have private duties to offset all emissions for which they are causally responsible, grounded in the general moral injunction against doing harm. Emissions do harm, therefore they must be neutralized. I argue that individuals' private duties to offset emissions cannot be grounded in a duty to do no harm, because there can be no such general duty. It is virtually impossible in our current social context―for those in developed countrie…Read more

    The Transfer of Duties: From Individuals to States and Back Again
    In Michael Brady & Miranda Fricker (eds.), The Epistemic Life of Groups, Oxford University Press. pp. 150-172. 2016.
    Individuals sometimes pass their duties on to collectives, which is one way in which collectives can come to have duties. The collective discharges its duties by acting through its members, which involves distributing duties back out to individuals. Individuals put duties in and get (transformed) duties out. In this paper we consider whether (and if so, to what extent) this general account can make sense of states' duties. Do some of the duties we typically take states to have come from individu…Read more

    The Motivation Question: Arguments from Justice, and from Humanity
    British Journal of Political Science 42 661-678. 2012.
    Which of the two dominant arguments for duties to alleviate global poverty, supposing their premises were generally accepted, would be more likely to produce their desired outcome? I take Pogge's argument for obligations grounded in principles of justice, a "contribution" argument, and Campbell's argument for obligations grounded in principles of humanity, an "assistance" argument, to be prototypical. Were people to accept the premises of Campbell's argument, how likely would they be to support …Read more

    Offsetting Class Privilege
    Journal of Practical Ethics 4 (1): 23-51. 2016.
    The UK is an unequal society. Societies like these raise significant ethical questions for those who live in them. One is how they should respond to such inequality, and in particular, to its effects on those who are worst-off. In this article, I’ll approach this question by focusing on the obligations of a particular group of those who are best-off. I’ll defend the idea of morally objectionable class-based advantage, which I’ll call ‘class privilege’, argue that class privilege can be non-culpa…Read more

    Benefiting from Failures to Address Climate Change
    Journal of Applied Philosophy 31 (4): 392-404. 2014.
    The politics of climate change is marked by the fact that countries are dragging their heels in doing what they ought to do; namely, creating a binding global treaty, and fulfilling the duties assigned to each of them under it. Many different agents are culpable in this failure. But we can imagine a stylised version of the climate change case, in which no agents are culpable: if the bad effects of climate change were triggered only by crossing a particular threshold, and it was reasonably, but m…Read more
