    The Asymmetry of Legitimacy
    Law and Philosophy 31 (5): 565-592. 2012.
    State legitimacy is often said to have two aspects: an internal and an external one. Internally, a legitimate state has the right to rule over its subjects. Externally, it has a right that outsiders not interfere with its domestic governance. But what is the relation between these two aspects? In this paper, I defend a conception of legitimacy according to which these two aspects are related in an importantly asymmetrical manner. In particular, a legitimate state’s external right to rule affords…Read more

    Immigration and self-determination
    Politics, Philosophy and Economics 14 (3): 270-290. 2015.
    This article asks whether states have a right to close their borders because of their right to self-determination, as proposed recently by Christopher Wellman, Michael Walzer, and others. It asks the fundamental question whether self-determination can, in even its most unrestricted form, support the exclusion of immigrants. I argue that the answer is no. To show this, I construct three different ways in which one might use the idea of self-determination to justify immigration restrictions and sh…Read more

    Uncertain rights against defense
    Social Philosophy and Policy 32 (2): 129-145. 2016.
    :In this essay, I defend a theory of liability to defensive force. The theory contains two elements. The first is a dual Lockean-inspired condition. The second aims to make this first condition consistent with problems arising from uncertainty. Drawing on recent work by Michael Zimmerman, I argue that the rights-based condition should be made sensitive to the evidence available to defenders.

    In defense of the ivory tower: Why philosophers should stay out of politics
    Philosophical Psychology 28 (7): 1045-1063. 2015.
    Many political theorists, philosophers, social scientists, and other academics engage in political activism. And many think this is how things ought to be. In this essay, I challenge the ideal of the politically engaged academic. I argue that, quite to the contrary, political theorists, philosophers, and other political thinkers have a prima facie duty to refrain from political activism. This argument is based on a commonsense moral principle, a claim about the point of political thought, and fi…Read more

    Assessing Law's Claim to Authority
    Oxford Journal of Legal Studies 31 (3): 481-501. 2011.
    The idea that law claims authority (LCA) has recently been forcefully criticized by a number of authors. These authors present a new and intriguing objection, arguing that law cannot be said to claim authority if such a claim is not justified. That is, these authors argue that the view that law does not have authority viciously conflicts with the view that law claims authority. I will call this the normative critique of LCA. In this article, I assess the normative critique of LCA, focusing predo…Read more

    What counts as original appropriation?
    Politics, Philosophy and Economics 8 (4): 355-373. 2009.
    I here defend historical entitlement theories of property rights against a popular charge. This is the objection that such theories fail because no convincing account of original appropriation exists. I argue that this argument assumes a certain reading of historical entitlement theory and I spell out an alternative reading against which it misfires. On this reading, the role of acts of original appropriation is not to justify but to individuate people’s holdings. I argue that we can identify wh…Read more
