    Unethical Consumption & Obligations to Signal
    Ethics and International Affairs 29 (3): 315-330. 2015.
    Many of the items that humans consume are produced in ways that involve serious harms to persons. Familiar examples include the harms involved in the extraction and trade of conflict minerals (e.g. coltan, diamonds), the acquisition and import of non- fair trade produce (e.g. coffee, chocolate, bananas, rice), and the manufacture of goods in sweatshops (e.g. clothing, sporting equipment). In addition, consumption of certain goods (significantly fossil fuels and the products of the agricultural i…Read more

    Do consumers’ ordinary actions of purchasing certain goods make them complicit in global labour injustice? To establish that they do, two things much be shown. First, it must be established that they are not more than complicit, for example that they are not the principal perpetrators. Second, it must be established that they meet the conditions for complicity on a plausible account. I argue that Kutz’s account faces an objection that makes Lepora and Goodin’s better suited, and defend the idea …Read more

    Enhanced weathering, in comparison to other geoengineering measures, creates the possibility of a reduced cost, reduced impact way of decreasing atmospheric carbon, with positive knock-on effects such as decreased oceanic acidity. We argue that ethical concerns have a place alongside empirical, political and social factors as we consider how to best respond to the critical challenge that anthropogenic climate change poses. We review these concerns, considering the ethical issues that arise (or w…Read more

    The Feasibility of Collectives' Actions
    Australasian Journal of Philosophy 90 (3): 453-467. 2012.
    Does ?ought? imply ?can? for collectives' obligations? In this paper I want to establish two things. The first, what a collective obligation means for members of the collective. The second, how collective ability can be ascertained. I argue that there are four general kinds of obligation, which devolve from collectives to members in different ways, and I give an account of the distribution of obligation from collectives to members for each of these kinds. One implication of understanding collect…Read more

    Collectives’ and individuals’ obligations: a parity argument
    Canadian Journal of Philosophy 46 (1): 38-58. 2016.
    Individuals have various kinds of obligations: keep promises, don’t cause harm, return benefits received from injustices, be partial to loved ones, help the needy and so on. How does this work for group agents? There are two questions here. The first is whether groups can bear the same kinds of obligations as individuals. The second is whether groups’ pro tanto obligations plug into what they all-things-considered ought to do to the same degree that individuals’ pro tanto obligations plug into w…Read more
