Do we as humans have no shared standards by which we can understand each other? Do we truly have divergent views about what constitutes good and evil, harm and welfare, dignity and humiliation, or is there some underlying commonality that wins out? These questions show up everywhere, from the debate over female circumcision to the UN Declaration of Human Rights. They become ever more pressing in an age of mass immigration, religious extremism and the rise of identity politics. So by what right do we judge particular practices as barbaric? Who are the real barbarians? This provocative book takes an enlightening look at what we believe, why we believe it and whether there really is an irreparable moral discord between 'us' and 'them'.

In this new edition of Foundations for Moral Relativism a distinguished moral philosopher tames a bugbear of current debate about cultural difference. J. David Velleman shows that different communities can indeed be subject to incompatible moralities, because their local mores are rationally binding. At the same time, he explains why the mores of different communities, even when incompatible, are still variations on the same moral themes. The book thus maps out a universe of many moral worlds without, as Velleman puts it, "moral black holes”. The six self-standing chapters discuss such diverse topics as online avatars and virtual worlds, lying in Russian and truth-telling in Quechua, the pleasure of solitude and the fear of absurdity. Accessibly written, this book presupposes no prior training in philosophy.

This volume is devoted solely to the topic of moral relativism. The 19 contemporary selections are nontechnical and fall under five main headings which include general issues of moral relativism, moral diversity, the coherence of moral relativism, and relativism, realism, and rationality.

No issue is more fateful for civilization than moral relativism. History knows not one example of a successful society which repudiated moral absolutes. Yet most attacks on relativism have been either pragmatic (looking at its social consequences) or exhorting (preaching rather than proving), and philosophers' arguments against it have been specialized, technical, and scholarly. In his typical unique writing style, Peter Kreeft lets an attractive, honest, and funny relativist interview a "Muslim fundamentalist" absolutist so as not to stack the dice personally for absolutism. In an engaging series of personal interviews, every conceivable argument the "sassy Black feminist" reporter Libby gives against absolutism is simply and clearly refuted, and none of the many arguments for moral absolutism is refuted.

In this book, David B. Wong defends an ambitious and important new version of moral relativism. He does not espouse the type of relativism that says anything goes, but he does start with a relativist stance against alternative theories such that there need not be only one universal truth. Wong proposes that there can be a plurality of true moralities existing across different traditions and cultures, all with one core human question as to how we can all live together.

Do moral questions have objective answers? In this great debate, Gilbert Harman explains and argues for relativism, emotivism, and moral scepticism. In his view, moral disagreements are like disagreements about what to pay for a house; there are no correct answers ahead of time, except in relation to one or another moral framework. Independently, Judith Jarvis Thomson examines what she takes to be the case against moral objectivity, and rejects it; she argues that it is possible to find out the correct answers to some moral questions. In her view, some moral disagreements are like disagreements about whether the house has a ghost. Harman and Thomson then reply to each other. This important, lively accessible exchange will be invaluable to all students of moral theory and meta-ethics.

Relativism is a hotly contested doctrine among philosophers, some of whom regard it as neither true nor false but simply incoherent. As Carol Rovane demonstrates in this analytical tour-de-force, the way to defend relativism is not initially by establishing its truth but by clarifying its content. The Metaphysics and Ethics of Relativism elaborates a doctrine of relativism that has a consistent logical, metaphysical, and practical significance. Relativism is worth debating, Rovane contends, because it bears directly on the moral choices we make in our lives. Three intuitive conceptions of relativism have been influential in philosophical discourse. These include the idea that certain unavoidable disagreements are irresolvable, leading to the conclusion that "both sides are right," and the idea that truth is always relative to context. But the most compelling, Rovane maintains, is the "alternatives intuition." Alternatives are truths that cannot be embraced together because they are not universal. Something other than logical contradiction excludes them. When this is so, logical relations no longer hold among all truth-value-bearers. Some truths will be irreconcilable between individuals even though they are valid in themselves. The practical consequence is that some forms of interpersonal engagement are confined within definite boundaries, and one has no choice but to view what lies beyond those boundaries with what Rovane calls "epistemic indifference." In a very real sense, some people inhabit different worlds--true in themselves, but closed off to belief from those who hold irreducibly incompatible truths.
