Moral relativism is often regarded as both fatally flawed and incompatible with liberalism. This book aims to show why such criticism is misconceived. First, it argues that relativism provides a plausible account of moral justification. Drawing on the contemporary relatavist and universalist analyses of thinkers such as Harman, Nagel and Habermas, it develops an alternative account of coherence relativism.

A new set of “Sustainable Development Goals” are currently being negotiated at the United Nations, and there is a widespread consensus that these goals must be “universal.” This article analyses what universality might mean in this context, and its normative significance as a guiding principle for the goals. After briefly introducing the Sustainable Development Goals as found in the current stage of the negotiations, thearticle proceeds in three sections that consider three different senses of universality. In the first, I outline (...) the most intuitive or straightforward sense of universality as a claim about the scope of the goals, with limited import for the content. In the second section, I expand on this idea by noting a widespread understanding of the content of the goals which might also be thought universal and which reflects a moral cosmopolitan constraint on the ambition of each goal. Universality is paired with, and contrasted against, the need fordifferentiation. In the final section, I examine this idea of differentiation, asking how and how far, the goals should allow for country context. From this discussion arises a third account of universality which incorporates a demand for fair burden-sharing. I consider, and ultimately caution against, this account of universality, even though the demand forfairness is crucial in its own right. (shrink)

Recently, alternatives to both the structure and content of ‘orthodox’ just war theory have been proposed by Jeff McMahan and David Rodin. In this paper, I draw on this debate to show that key ideas in just war theory can be disputed in both of these respects. More broadly, it is unclear how we should assess the debate between differing conceptions of individual principles (such as just cause and proportionality) and the competing wider theories in which they might be situated. (...) I employ the idea of reflective equilibrium, taken from John Rawls, to show how these conflicting viewpoints might be understood and assessed. I argue, then, that contemporary just war theory faces both important questions of substance, and a set of difficult meta-theoretical issues concerning the grounds on which competing just war theories can be assessed. Futhermore, I contend, this should influence the character of – and our expectations for – real-world just war institutions. (shrink)

A demand for public justification characterises many contemporary arguments for liberal principles. Nagel notes, ‘the task of discovering the conditions of legitimacy is traditionally conceived as...

As some thinkers have sought in the concept of global civil society an ethically driven site of deliberation and even resistance, so others have criticized global civil society for its lack of legitimacy and representativeness. This article attempts to answer these criticisms ? at least in part ? by invoking a moral commitment to the value of justification. I argue that the idea of justification, when examined, offers us a particular understanding of legitimacy which would be attainable for global civil (...) society actors. The article begins by setting out the case for concern about the legitimacy of global civil society. I then outline a certain understanding of justification, showing how a commitment to this conception provides both a response to critics of global civil society and an ethical baseline for humane actors within global civil society. I move on to trace the significance of the moral relevance of justification for actors' strategies. Lastly, however, I highlight the difficulty of justification in a diverse world. This is to say that the issues of legitimacy and strategy facing global civil society are only made more tractable, not dissolved, by an appeal to the importance of justification. (shrink)
