The facts of global poverty are staggering. Consider, for instance, how 1.5 billion people subsist below the international poverty line, which means about a quarter of the world's current population lives in poverty. There is much talk about how freer markets will help the situation of these people, in particular how it will help the worst off. So far the evidence for this claim is fairly unclear. ‘At any rate, on several accounts, alleviating the worst aspects of poverty would impose fairly small costs on us in more affluent countries, yet we continue to do very little about alleviating this situation. For instance, a 1 per cent tax on world product would make enormous inroads in lifting people out of poverty. Alternatively, simply a shift in priorities could do this without any added taxes: a 1 per cent decrease in military spending in the developed world and a 10 per cent decrease in military spending in the developing world could have the same effect.

What kinds of principles of justice should a cosmopolitan support? In recent years some have argued that a cosmopolitan should endorse a Global Difference Principle. It has also been suggested that a cosmopolitan should support a Principle of Global Equality of Opportunity. In this paper I examine how compelling these two suggestions are. I argue against a Global Difference Principle, but for an alternative Needs-Based Minimum Floor Principle (where these are not co-extensive, as I explain). Though I support a negative version of the Global Equality of Opportunity Principle, I argue that a more positive version of the ideal remains elusive.

There is much current and growing interest in theorizing about global justice. Contemporary events in the world probably account for most of this, but if any philosophical text can be identified as igniting theorists' relatively newly found interest, it must be John Rawls's influential book, The Law of Peoples . There is a lively debate between critics and advocates of Rawls's approach, and much theorizing about global justice is framed in terms of that exchange. Because of its enormous influence in shaping the terms of discussion, familiarity with this work is important for being able to participate in the current theoretical conversations about global justice. In this article I examine that debate and assess the state of play. I briefly outline the central themes of Law of Peoples in section 2 and criticism these ideas attracted in 3. In section 4 I cover some defenses of Rawls's account. In section 5, I assess the state of play and implications for debates about global justice

There has been much interest in cosmopolitan models of democracy in recent times. Arguably, the most developed of these is the model articulated by David Held, so it is not surprising that it has received the most attention and criticism. In this paper, I outline Held's model of cosmopolitan democracy and consider the objections Will Kymlicka raises to this account. I argue that Kymlicka's objections do not undermine Held's central claims and that Held's cosmopolitanism remains a very promising model that deserves further attention.

Do any needs defensibly make claims on anyone? If so, which needs and whose needs can defensibly do this? What are the grounds for our responsibilities to meet others' needs, when we have such responsibilities? The distinguished contributors to this volume consider these questions as they evaluate the moral force of needs. They approach questions of obligation and moral importance from a variety of different theoretical perspectives, including contractarian, Kantian, Aristotelian, rights-based, egalitarian, liberal, and libertarian perspectives
