I defend the cosmopolitan instrumentalist theory of secession, according to which a group has a right to secede only if this would promote cosmopolitan justice. I argue that the theory is preferable to other theories of secession because it is an entailment of cosmopolitanism, which is independently attractive, and because, unlike other theories of secession, it allows us to give the answers we want to give in cases like secession of the rich or secession that would make things worse for (...) minorities. I defend the view against the objections that it allows for colonialism and annexation, that it is not a distinct theory, and that it is impractical. (shrink)

Can a liberal state exclude illiberal immigrants in order to preserve its liberal status? Hrishikesh Joshi has argued that liberalism cannot require a commitment to open borders because this would entail that liberalism is committed to its own demise in circumstances in which many illiberal immigrants aim to immigrate into a liberal society. I argue that liberalism is committed to its own demise in certain circumstances, but that this is not as bad as it may appear. Liberalism’s commitment to its (...) own demise is merely a reflection of the fact that it must take into account the rights of outsiders, not just the rights of existing citizens, and of the fact that circumstances of injustice can sometimes leave liberal societies with no correct choice.

It is widely believed that immigrants, after some time, acquire a claim to naturalize and become citizens of their new state. What explains this claim? Although existing answers (may) succeed in justifying some of immigrants' rights claims, they cannot justify the claim that immigrants are owed the opportunity to naturalize because these theories lack a sufficiently rich account of the purpose of citizenship. To fill this gap, I offer a novel egalitarian account of citizenship. Citizenship, on this account, partially protects (...) immigrants against social hierarchy by realizing social equality in a publicly accessible manner. This explains claims to naturalize. (shrink)
