My apologies for the delay in posting the second half of my reply to the symposium. I was traveling. Let me repeat at the outset my deep appreciation for the insightful comments provided by the contributors to this symposium. This is the sort of exchange that makes intellectual life rewarding. Given the delay since the original postings, I did not want to assume that readers of this post would remember what was said in the earlier ones, and I’ve tried to write this in a way that will be intelligible on its own. I take up here the six contributions that I did not discuss in the previous post. I’ll begin with David Owen, Michael Blake, Kieran Oberman and Ryan Pevnick, all of whom have related concerns. At the end, I’ll discuss the posts by Brian Weatherson and Patti Lenard.
In various, sometimes overlapping ways, David, Michael, Kieran and Ryan have raised questions about my theory of social membership. To recall (or, for those who have not read the book, to summarize), the central claim of that theory is that immigrants become members of society over time and their social membership gives them a moral claim to most of the legal rights that citizens enjoy and eventually to citizenship itself. It is important to note, however, that I do not start with a general theory of social membership that I try to justify on the basis of abstract principles and then apply to particular issues. Rather I start with the actual practices of democratic states and ask whether these practices seem to make moral sense. It is only after I have explored arguments about particular practices that I try to show that the idea of social membership is a common thread in many of these arguments. Moreover, my theory of social membership is not presented as a full account of why immigrants are morally entitled to legal rights. I contend that immigrants also have claims to legal rights based on the duty of every state to protect the human rights of anyone within the state’s jurisdiction and based on other considerations like reciprocity and proportionality as well. I think that this way of doing political theory “from the ground up” differs from the approach of some of my interlocutors, especially Kieran and Ryan. My approach is likely to be less systematic and involve more balancing of competing considerations, but I think that it is more closely connected to ordinary moral views, even when, as in the open borders chapters, it leads to radical conclusions.
