11The Ethics of State Responses to Refugees (review)Notre Dame Philosophical Reviews. 2026.The concept of the refugee is currently under several distinct forms of pressure. Populists, in many wealthy states, have demonized the figure of the refugee and have succeeded in mobilizing popular opposition to the legal rights of refugees. Public support for the rights of refugees is at, or near,…

22In the Shadow of Democratic ViolenceEthics and International Affairs 39 (3): 206-214. 2025.Shmuel Nili’s Beyond the Law’s Reach? is an inquiry into the moral duties of the world’s established democracies in a world rife with violent and undemocratic states. Nili argues that these “consolidated” democratic states are “entangled” with the leaders of such violent polities—and uses this entanglement to derive an elegant and plausible series of political duties. In response, this essay seeks to undermine the distinction between the established democracies and the violent states, by showing…Read more

18On Money, God, and Dogmatic Liberalism: A Reply to my CriticsMoral Philosophy and Politics 3 (1): 109-117. 2016.Darrel Moellendorf, David Owen, and Lea Ypi have offered some subtle and powerful criticisms of the view I defend in Debating Brain Drain. I here focus on two broad category of criticism. The first is that my use of metaphor is faulty. I try to demonstrate that the right to emigrate is similar in moral strength to the right to freely exercise one’s religion, and not morally akin to the (non-existent) right to be free from paying taxes. I defend the proposition that the taking of money from peopl…Read more

17Debating Brain Drain: An OverviewMoral Philosophy and Politics 3 (1): 21-35. 2016.In my chapters in Debating Brain Drain, I offer some reasons for thinking that states may not seek to prevent the emigration of their own citizens – even when those citizens have rare and desirable skills, and might use those skills to improve the lot of their fellow citizens. These arguments are developed in response to those contrary arguments given by Gillian Brock in her own chapters. I try to establish my conclusions by arguing against the empirical and philosophical bases of arguments in f…Read more

33Climate Migration, Moral Dilemmas, and Moral MotivationEthics and International Affairs 39 (1): 37-49. 2025.Theories of liberal justice depend upon ideas of how much we can expect ordinary people to be motivated by the moral interests of others; there are limits to the motivational power of such notions as altruism and sympathy. This means, however, that the theories of justice we have may have difficulty in understanding how to rightly respond to the moral claims that might emerge in the face of widespread migration in response to climate change. This essay argues that liberal states may face a dilem…Read more

72Modesty, toleration, and persuasionEuropean Journal of Political Theory 24 (3): 445-453. 2025.Lucia Rafanelli's analysis of reform intervention is both timely and philosophically powerful. This paper asks two questions about the limits, and proper implications, of her methodology – both of which have to do with the notion of modesty, understood as a moral virtue. The first asks whether or not principled illiberal regimes have a moral right, on her account, to reform intervention against the liberalism of liberal democratic states. The second asks about the extent to which persuasive and …Read more

88Sanctuary Cities and Non-RefoulementEthical Theory and Moral Practice 23 (2): 457-474. 2020.More than two hundred cities in the United States have now declared themselves to be sanctuary cities. This declaration involves a commitment to non-compliance with federal law; the sanctuary city will refuse to use its own juridical power – including, more crucially, its own police powers – to assist the federal government in the deportation of undocumented residents. We will argue that the sanctuary city might be morally defensible, even if deportation is not always wrong, and even if the fede…Read more

283Is there a human right to free movement? Immigration and original ownership of the earthNotre Dame Journal of Law, Ethics and Public Policy 23 (1): 166. 2009.1. Among the most striking features of the political arrangements on this planet is its division into sovereign states.1 To be sure, in recent times, globalization has woven together the fates of communities and individuals in distant parts of the world in complex ways. It is partly for this reason that now hardly anyone champions a notion of sovereignty that would entirely discount a state’s liability the effects that its actions would have on foreign nationals. Still, state sovereignty persist…Read more

112Migration, territoriality, and cultureIn Ryberg Jesper & Petersen Thomas (eds.), New Waves in Applied Ethics, Palgrave. 2008.Little work has been done to explore the moral foundations of the state’s right to territory.1 In modern times, the state has mostly been assumed to be a territorial unit, and no need was perceived to reflect on precisely what justifies its territorial jurisdiction. The state’s territoriality is related to another topic that has remained under-theorized: immigration. There is, moreover, an obvious relationship between these topics: the more powerful a state’s rights over its territory, the more …Read more

75Voluntary and Involuntary Migrants: On Migration, Safe Third Countries, and the Collective Unfreedom of the ProletariatEthics and International Affairs 37 (4): 427-451. 2023.The claims of those who are compelled to migrate are, in general, taken to be more urgent and pressing than the claims of those who were not forced to do so. This article does not defend the moral relevance of voluntarism to the morality of migration, but instead seeks to demonstrate two complexities that must be included in any plausible account of that moral relevance. The first is that the decision to start the migration journey is distinct from the decision to stop that journey, through rese…Read more

68Migration and ManipulationPublic Affairs Quarterly 37 (3): 174-187. 2023.Much modern discussion of the morality of migration begins with the concept of coercion, and takes the coercive nature of border enforcement as especially salient in the moral analysis of migration policy. Much migration control, however, begins not with overt coercion, but with what I term manipulations; these are ways of making migration more difficult that do not resemble canonical cases of coercion. Examples include the alteration of the physical pathways between states, attempts to deceive …Read more

150Global cities, global justice?Journal of Global Ethics 14 (3): 332-352. 2018.The global city is a contested site of economic innovation and cultural production, as well as profound inequalities of wealth and life chances. These cities, and large cities that aspire to ‘global’ status, are often the point of entry for new immigrants. Yet for political theorists (and indeed many scholars of global institutions), these critical sites of global influence and inequality have not been a significant focus of attention. This is curious. Theorists have wrestled with the nature and…Read more

41Unwanted Compatriots: Alienation, Migration, and Political AutonomyEthics and International Affairs 35 (4): 491-501. 2021.In Territorial Sovereignty: A Philosophical Exploration, Anna Stilz argues that legitimate political authority requires the actual—rather than hypothetical—consent of the governed. I argue, however, that her analysis of that consent is inconsistent, in the weight it ascribes to the felt desire to refrain from doing politics with some particular group of people. In the context of secession and self-determination, the lack of actual consent to shared political institutions is weighty enough to ren…Read more

130What is the Border For?Journal of Moral Philosophy 17 (4): 379-397. 2020.Many discussions of the moral dimensions of borders emphasize how those borders foster and sustain a national community. In this paper, I discuss three distinct sorts of goods that might be best preserved in the presence of state borders. The first of these is decolonization; I argue that undermining colonial structures might require political institutions with the right to refuse unwanted outsiders. The second of these is social solidarity; we might find that the inability to exclude outsiders …Read more

77Are Citizenship Tests Necessarily Illiberal?Ethical Theory and Moral Practice 22 (2): 313-329. 2019.In recent years, many philosophers have argued that it is inherently illiberal to make citizenship for migrants conditional on a test. On these arguments, liberalism itself demands either that no test be administered, or that the test be so easy as to serve merely a symbolic function. In this paper, I make two claims in response to these ideas. The first is that a citizenship test - even a difficult one - is not inherently illiberal, when what is tested for reflects the actual backdrop of knowle…Read more

90What should be done to address losses associated with ‘medical brain drain’?Journal of Medical Ethics 43 (8): 558-559. 2017.The lack of human resources available to address enormous contemporary healthcare needs is ‘one of the most pressing global health issues of our time’.1 The WHO has estimated the shortfall at approximately 4.3 million healthcare professionals.2 The shortages are most acutely felt in low/middle-income countries, where the scale of the problem sometimes threatens the very viability of even rudimentary healthcare systems. The shortages are exacerbated by the phenomenon known as ‘brain drain’ where,…Read more
