In this paper I examine the method Aristotle uses in the inquiry into the nature of happiness in the "Nicomachean Ethics". Through analysis of some of the method's features, I explain why labelling it "the onion approach to developing and fleshing out a hypothesis" is appropriate. I show how Aristotle derives a set of necessary conditions and a set of other criteria, or reliable indicators, which any adequate account of the nature of happiness must meet. There are definite benefits to understanding the strategy in these terms. Having derived a set of criteria that an adequate account must meet, we are in a position to examine which of the two rival hypotheses about the nature of happiness best satisfies the criteria. The life of theoretical study emerges as the clear winner at meeting the criteria Aristotle himself imposes on an adequate account.

Justice and Needs Is it somehow a requirement of justice that we meet people's needs? So, for instance, do people in need of certain goods necessary to sustain life deserve help from those not (similarly) in need because this is a requirement of justice? According to two recent arguments (one offered by Wiggins and the other offered by Braybrooke), justice requires that needs be met. Wiggins uses a rights-based argument and Braybrooke deploys an argument which relies pivotally on the concept of respect. In this article I examine these two strategies for arguing for a connection between justice and meeting needs and show that both strategies not only fail to establish that needs should be met, but, moreover, both strategies face substantial challenges if they are ever to be successful.

Cosmopolitans believe that all human beings have equal moral worth and that our responsibilities to others do not stop at borders. Various cosmopolitans offer different interpretations of how we should understand what is entailed by that equal moral worth and what responsibilities we have to each other in taking our equality seriously. Two suggestions are that a cosmopolitan should endorse a 'global difference principle' and a 'principle of global equality of opportunity'. In the first part of this paper I examine whether these two suggestions are compelling. I argue against a global difference principle, but for an alternative 'needs-based minimum floor principle' (where these are not coextensive, as I explain). I develop a model of cosmopolitan justice, which allows us to address not only matters of global distributive justice, but other global justice issues as well. Though I support what I refer to as a negative version of the global equality of opportunity principle, I argue that a more positive version of the ideal remains elusive. In the second part of this paper, I reflect on what bearing these results have on two central sets of questions: First, what kind of ideal are we after in the domain of cosmopolitan justice and what practical implications can we reasonably expect from it? Second, what sort of ideal of egalitarianism is compelling and does my model of cosmopolitan justice adequately reflect the legitimate concerns of egalitarians?
