On nationality and global equality: a reply to Holtug

摘要

I here defend some of the positions taken in National Responsibility and Global Justice against criticisms by Nils Holtug. I reinforce my suggestion that claims about national membership being ‘morally arbitrary’ are question begging and try to show how such membership can legitimately serve as a source of special obligations. I examine the claim that the problems involved in constructing a ‘currency’ of global justice also arise in the domestic context and suggest that appealing to ‘welfare’ as the relevant currency is not a useful way of responding to cultural differences. Finally, I respond to the hypothetical case of an unequally distributed life-extending vitamin by arguing that the discovery of such a substance would change our understanding of a normal human life, and thereby raise the bar of sufficiency.
