    Despite a recent explosion of interest in the ethics of armed conflict, the traditional just war criterion that war be waged by a legitimate authority has received relatively little attention. Moreover, of those theorists who have addressed the criterion, many are deeply skeptical about its moral significance. This article aims to add some clarity and precision to the authority criterion and the debates surrounding it, and to suggest that this skepticism may be too quick. The first section analy…Read more

    This paper proposes a novel reinterpretation of the familiar, if inchoate, thought that paternalism offends against an ideal of personal sovereignty. The central idea is that (competent) persons have a particular kind of normative power. Just as each of us has the right to control how others are permitted to use our bodies or property, we each have a structurally similar right to control how others are permitted to use our good. When others seek to benefit us without adequately consulting our wi…Read more

    If states are permitted to create and maintain a military force, by what means are they permitted to do so? This article argues that a theory of just recruitment should incorporate a concern for moral risk. Since the military is a morally risky profession for its members, recruitment policies should be evaluated in terms of how they distribute moral risk within a community. We show how common military recruitment practices exacerbate and concentrate moral risk exposure, using the UK as a case st…Read more

    Why Paternalism is Wrong (When it is Wrong)
    Philosophy and Phenomenological Research. 2026.

The central idea is that (competent) persons have a particular kind of normative power. Just as each of us has the right to control whether others are permitted to use our bodies or property, we each have a structurally similar right to control whether others are permitted to use our good.

    Authority and Harm
    In David Sobel, Peter Vallentyne & Steven Wall (eds.), Oxford Studies in Political Philosophy, Volume 3, Oxford University Press. pp. 252-278. 2017.
    This paper argues that certain common views about, respectively, the justification of harm and the moral limits of legitimate authority require revision. It defends two main claims. The first concerns agents who are commanded to inflict serious harm on others. It is argued that agents can be morally required to obey such commands, including in (at least some) cases where harming would be morally prohibited in the absence of the command. The argument thus defends a novel ‘authority-based’ justifi…Read more

    'Filling the Ranks': Moral Risk and the Ethics of Military Recruitment
    American Political Science Review 118 (4): 1763-1777. 2024.

This paper argues that a theory of just recruitment should incorporate a concern for moral risk. Since the military is a morally risky profession for its members, recruitment policies should be evaluated in terms of how they distribute moral risk within a community.

    Chater & Loewenstein argue that i-frame research has been coopted by private interests opposed to system-level reform, leading to ineffective interventions. They recommend that behavioural scientists refocus on system-level interventions. We suggest that the influence of private interests on research is problematic for wider normative and epistemic reasons. A system-level intervention to shield research from private influence is needed.

    The Scope of the Means Principle
    Journal of Moral Philosophy 20 (5-6): 439-460. 2023.
    This paper focuses on Quong’s account of the scope of the means principle (the range of actions over which the special constraint on using a person applies). One the key ideas underpinning Quong’s approach is that the means principle is downstream from an independent and morally prior account of our rights over the world and against one another. I raise three challenges to this ‘rights first’ approach. First, I consider Quong’s treatment of harmful omissions and argue that Quong’s view generates…Read more

    Legitimate Authority and the Ethics of War: A Map of the Terrain
    Ethics and International Affairs 2 (31): 169-189. 2017.
    Despite a recent explosion of interest in the ethics of armed conflict, the traditional just war criterion that war be waged by a “legitimate authority” has received less attention than other components of the theory. Moreover, of those theorists who have addressed the criterion, many are deeply skeptical about its moral significance. This article aims to add some clarity and precision to the authority criterion and to debates surrounding it, and to suggest that this skepticism may be too quick.…Read more

    Wrongful Observation
    Philosophy and Public Affairs 47 (1): 104-137. 2019.
    According to common-sense morality, agents can become morally connected to the wrongdoing of others, such that they incur special obligations to prevent or rectify the wrongs committed by the primary wrongdoer. We argue that, under certain conditions, voluntary and unjustified observation of another agent’s degrading wrongdoing, or of the ‘product’ of their wrongdoing, can render an agent morally liable to bear costs for the sake of the victim of the primary wrong. We develop our account with pa…Read more

    Law and Morality at War offers a broadly instrumentalist defense of the authority of the laws of war: these laws serve combatants by helping them come closer to doing what they have independent moral reason to do. We argue that this form of justification sets too low a bar. An authority’s directives are not binding, on instrumental grounds, if the subject could, within certain limits, adopt an alternative, and superior, means of conforming to morality’s demands. It emerges that Haque’s argument …Read more

    Authority and Harm
    Oxford Studies in Political Philosophy 3 252-278. 2017.
    This paper explores the connections between two central topics in moral and political philosophy: the moral legitimacy of authority and the ethics of causing harm. Each of these has been extensively discussed in isolation, but relatively little work has considered the implications of certain views about authority for theories of permissible harming, and vice versa. As I aim to show, reflection on the relationship between these two topics reveals that certain common views about, respectively, the…Read more
