In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

Liberal political theory sees justice as the "first virtue" of a good society, the virtue that guides individuals' conceptions of their own good, and protects the equal liberty of all to pursue their ends, so long as these ends and pursuits are just. But ever since Marx's declaration that "liberty as a right of man is not founded upon the relations between man and man, but rather upon the separation of man from man...,"i liberal society has been frequently criticized for (...) falling seriously short of the conditions of a good society.ii A prominent recent criticism of this sort has been voiced by "communitarians," who charge that the primacy of rights in liberalism reveals a failure to appreciate the value of friendship and community, and tends to undermine their possibility.iii My aim in this paper is to defend liberal political theory, understood as the theory that justifies a polity of individual rights and justice, against this charge.iv My main argument will be directed at the assumption that there is an inherent tension between rights and justice on the one hand, and familial love and friendship on the other. According to the communitarian, two or more individuals constitute a community when they share a common conception of the good, and see this good as partly constitutive of their identities or selves.v Such "constitutive community," in Michael Sandel's words, may be a close friendship or family relationship, or an intermediate association such as a neighborhood organization, or a comprehensive political community. The communitarian charges that in making justice the first virtue of social institutions, liberalism undermines community at all levels, and this for two reasons. First, liberalism demands that we revise or surrender our conceptions of the good - including our attachments and commitments to family and friends - if they should turn out to be unjust. But this demand, the communitarian claims, requires attitudes 2 that are inconsistent with these attachments and commitments.. (shrink)

This is a new analysis of rights, particularly of the paradigm: the claim-right. The new analysis makes better sense of rights than the leading alternatives do. The new analysis handles all of the well-known counterexamples to the Will and Interest theories; it seems not to generate counterexamples of its own; and it solves many long-standing puzzles in the theory of rights. Moreover, the central concepts of the new theory are as salient and forceful as are rights themselves.

Legal systems divide the world into persons and property, treating animals as property. Some animal rights advocates have proposed treating animals as persons. Another option is to introduce a third normative category. This raises questions about how normative categories are established. In this article I argue that Kant established normative categories by determining what the presuppositions of rational practice are. According to Kant, rational choice presupposes that rational beings are ends in themselves and the rational use of the earth’s resources (...) presupposes that human beings have rights. I argue that rational choice also presupposes that any being for whom things can be good or bad must be regarded as an end in itself, and that the use of the world’s resources presupposes that any being who depends on those resources has rights. Although the other animals do not engage in rational practice, our own rational practice requires us to give them standing. (shrink)
