Many poor and oppressed people wish to leave their countries of origin in the third world to come to affluent Western societies. This essay argues that there is little justification for keeping them out. The essay draws on three contemporary approaches to political theory - the Rawlsian,the Nozickean, and the utilitarian - to construct arguments for open borders. The fact that all three theories converge upon the same results on this issue, despite their significant disagreements on others, strengthens the case (...) for open borders and reveals its roots in our deep commitment to respect all human beings as free and equal moral persons. The final part of the essay considers communitarian objections to this conclusion, especially those of Michael Walzer. (shrink)

The mass movement of people across the globe constitutes a major feature of world politics today. -/- Whatever the cause of the movement - often war, famine, economic hardship, political repression or climate change - the governments of western capitalist states see this 'torrent of people in flight' as a serious threat to their stability and the scale of this migration indicates a need for a radical re-thinking of both political theory and practice, for the sake of political, social and (...) economic justice. -/- This book argues that there is at present a serious gap between the legal and social practices of immigration and naturalisation in liberal democratic states and any theoretical justification for such practices that can be made within the tradition of liberal political philosophy. How can liberal states develop institutions of democratic citizenship and at the same time justifiably exclude 'outsiders' from participating in those institutions? The book examines various responses to this contradiction within the liberal tradition, and finds none of them satisfactory - there are no consistently liberal justifications for immigration control and this has serious implications both for liberal practice and theory.
