This article attacks the view that global justice should be understood in terms of a global principle of equality. The principle mainly discussed is global equality of opportunity – the idea that people of similar talent and motivation should have equivalent opportunity sets no matter to which society they belong. I argue first that in a culturally plural world we have no neutral way of measuring opportunity sets. I then suggest that the most commonly offered defences of global egalitarianism – the cosmopolitan claim that human lives have equal value, the argument that a persons nationality is a morally arbitrary characteristic, and the more empirical claim that relationships among fellow-nationals are no longer special in a way that matters for justice – are all defective. If we fall back on the idea of equality as a default principle, then we have to recognize that pursuing global equality of opportunity systematically would leave no space for national self-determination. Finally, I ask whether global inequality might be objectionable for reasons independent of justice, and argue that the main reason for concern is the inequalities of power that are likely to emerge in a radically unequal world.

Cosmopolitanism, originally a doctrine of world citizenship, has come in recent political philosophy to mean simply an ethical outlook in which every human being is equally an object of moral concern. However ethical cosmopolitans slide from this moral truism to deny, controversially, that as agents we have special duties of limited scope. Political communities create relations of reciprocity between their citizens and pursue projects that reflect culturally specific values and beliefs, generating special duties among fellow-members. Strong cosmopolitanism would require the creation of a world government, and this could only be an imperialist project in which existing cultural differences were either nullified or privatised.

How should we decide when to be altruistic? who are the poor we ought to help? Empirical evidence reveals that in practice altruistic behaviour is strongly influenced by contextual factors such as the cost of helping, perceptions of the person in need, and the number of other people who are in a position to offer help. Philosophers often argue that we should discount such factors, but I claim that altruism is better understood as doing one's proper share of the work of meeting nee. Three possible mechanisms for achieving this are explored: creating formal institutions to discharge our altruistic duties, imposing a legal duty of rescue on individuals, and fostering norms of responsibility that pick out individuals as salient helpers.

This chapter outlines the main ideas of my book National responsibility and global justice. It begins with two widely held but conflicting intuitions about what global justice might mean on the one hand, and what it means to be a member of a national community on the other. The first intuition tells us that global inequalities of the magnitude that currently exist are radically unjust, while the second intuition tells us that inequalities are both unavoidable and fair once national responsibility is allowed to operate. This conflict might be resolved either by adopting a cosmopolitan theory of justice (which leaves no room for national responsibility) or by adopting a ‘political’ theory of justice (which denies that questions of distributive justice can arise beyond the walls of the sovereign state). Since neither resolution is satisfactory, the chapter defends the idea of national responsibility and proposes a new theory of global justice, whose main elements are the protection of basic human rights worldwide, and fair terms of interaction between independent political communities.

Lea Ypi’s book Global Justice and Avant-Garde Political Agency is a very rich book, and one cannot hope to do it justice in the space of a short discussion.1 In this commentary I will focus on the second part of her title, reserving for another occasion her interesting discussion of equality and sufficiency as principles of global justice. Here I will restrict myself to some remarks about method in political theory, and especially the idea of avant-garde political theory, which is perhaps Ypi’s most distinctive contribution
