Abstract

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 could reduce the willingness of insiders to voluntarily comply with political institutions. The final of these is risk and insurance; the border sustains the ability of a political society to internalize the costs and benefits of political decisions about social welfare. All three of these, I suggest, are important additions to our collective discussions about migration, since none of these goods depend upon our attaching any ethical value to nationality itself.
