Originally published in 1988, this landmark study develops its own positive account of the nature and foundations of moral judgement, while at the same time serving as a guide to the range of views on the matter which have been given in modern western philosophy. The book addresses itself to two main questions: Can moral judgements be true or false in that fundamental sense in which a true proposition is one which describes things as they really are? Are rational methods available in ethics which can be expected to produce convergence on shared moral views on the part of those who use them intelligently?

A systematic analysis considers the objectivity of ethics, the relationship between the moral point of view and a scientific or naturalist worldview and its role in a person's rational lifespan.

Rectifying misrepresentations of Popperian thought with a historical approach to Popper’s philosophy, Gattei reconstructs the logic of Popper’s development to show how one problem and its tentative solution led to a new problem.

When do governments merit our allegiance, and when should they be denied it? Ian Shapiro explores this most enduring of political dilemmas in this innovative and engaging book. Building on his highly popular Yale courses, Professor Shapiro evaluates the main contending accounts of the sources of political legitimacy. Starting with theorists of the Enlightenment, he examines the arguments put forward by utilitarians, Marxists, and theorists of the social contract. Next he turns to the anti-Enlightenment tradition that stretches from Edmund Burke to contemporary post-modernists. In the last part of the book Shapiro examines partisans and critics of democracy from Plato’s time until our own. He concludes with an assessment of democracy’s strengths and limitations as the font of political legitimacy. The book offers a lucid and accessible introduction to urgent ongoing conversations about the sources of political allegiance.

Reconstructing Rawls has one overarching goal: to reclaim Rawls for the Enlightenment—more specifically, the Prussian Enlightenment. Rawls’s so-called political turn in the 1980s, motivated by a newfound interest in pluralism and the accommodation of difference, has been unhealthy for autonomy-based liberalism and has led liberalism more broadly toward cultural relativism, be it in the guise of liberal multiculturalism or critiques of cosmopolitan distributive-justice theories. Robert Taylor believes that it is time to redeem A Theory of Justice’s implicit promise of a universalistic, comprehensive Kantian liberalism. Reconstructing Rawls on Kantian foundations leads to some unorthodox conclusions about justice as fairness, to be sure: for example, it yields a more civic-humanist reading of the priority of political liberty, a more Marxist reading of the priority of fair equality of opportunity, and a more ascetic or antimaterialist reading of the difference principle. It nonetheless leaves us with a theory that is still recognizably Rawlsian and reveals a previously untraveled road out of Theory—a road very different from the one Rawls himself ultimately followed.

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.
