Epicurus is one of the first social contract theorists, holding that justice is an agreement neither to harm nor be harmed. He also says that living justly is necessary and sufficient for living pleasantly, which is the Epicurean goal. Some say that there are two accounts of justice in Epicurus -- one as a personal virtue, the other as a virtue of institutions. I argue that the personal virtue derives from compliance with just social institutions, and so we need to (...) (...) attribute only one account of justice to Epicurus. I show how this interpretation makes sense of claims about justice by Epicurus and his followers, including Hermarchus, Lucretius, and Diogenes of Oinoanda. (shrink)

The result is nothing less than a fundamental reorientation of moral theory that enables it at last to account for morality's supreme authority--an account that ...

Contractualism/Contractarianism collects, for the first time, both major classical sources and central contemporary discussions of these important approaches to philosophical ethics. Edited and introduced by Stephen Darwall, these readings are essential for anyone interested in normative ethics.

Harsanyi defends utilitarianism by means of an axiomatic proof and by what he calls the equiprobability model. Both justifications of utilitarianism aim to show that utilitarian ethics can be derived from Bayesian rationality and some weak moral constraints on the reasoning of rational agents. I argue that, from the perspective of Bayesian agents, one of these constraints, the impersonality constraint, is not weak at all if its meaning is made precise, and that generally, it even contradicts individual rational agency. Without (...) the impersonality constraint, Harsanyi's two justifications of utilitarianism on the grounds of Bayesian rationality fail. As an alternative, I develop a contractarian framework that is compatible with individual rational agency and Harsanyi's central assumptions, and that allows the derivation of moral conclusions on the grounds of Bayesian rationality. The developed framework offers a novel justification of contractarian ethics and may best be described as a combined version of Harsanyi's equiprobability model and Rawls' original position.

In this article, I derive a weak version of Kant's categorical imperative within an informal game-theoretic framework. More specifically, I argue that Hobbesian agents would choose what I call the weak principle of universalization, if they had to decide on a rule of conflict resolution in an idealized but empirically defensible hypothetical decision situation. The discussion clarifies (i) the rationality requirements imposed on agents, (ii) the empirical conditions assumed to warrant the conclusion, and (iii) the political institutions that are necessary (...) to implement the derived principle. The analysis demonstrates the moral significance of the weak principle of universalization and its epistemic advantage over the categorical imperative. (shrink)

Jean Hampton argues that we can detect exploitation in personal relationships by thinking about what we would agree to were we to set aside the emotional benefits we receive from those relationships. Hampton calls her account "feminist contractarianism," but it has recently been critiqued as decidedly unfeminist, on the grounds that it is hostile to women's interests and women's values. Furthermore, Hampton's requirement that we imaginatively distance ourselves from our emotional connections to our loved ones--the key element in her contractarian (...) test--is simply ad hoc. In this essay, I will evaluate these objections and offer a new justification for Hampton's test. I conclude that feminist contractarianism is not only a useful tool for detecting exploitation in the family, it is also deserving of its feminist label. (shrink)

Despite an impressive philosophical pedigree, contractualism (or contractarianism) has only been properly developed in two ways: by appeal to the idea of an instrumentally rational bargain or contract between self-interested individuals (Hobbesian contractualism) and by appeal to the idea of a substantively reasonable agreement among individuals who regard one another as free and equal persons warranting equal moral respect (Kantian contractualism). Both of these existing models of contractualism are susceptible to apparently devastating objections. In this article, I outline a third, (...) `deliberative' model of contractualism, which is based on the idea of a deliberatively rational agreement and which, I argue, represents a significant improvement on the Hobbesian and Kantian models in certain important respects. Key Words: contractualism • contractarianism • deliberation • deliberative rationality • Scanlon • Gauthier. (shrink)

Mark Rowlands argues that, contrary to the dominant view, a Rawlsian theory of justice can legitimately be applied to animals. One of the implications of doing so, Rowlands argues, is an end to animal experimentation. I will argue, contrary to Rowlands, that under a Rawlsian theory there may be some circumstances where it is justifiable to use animals as experimental test subjects (where the individual animals are benefited by the experiments).

David Gauthier's book represents the culmination of his work over the last twenty years on the theory of rational choice and on contractarian moral theory. It is the most important book on contractarianisni since Rawls‘ A Theory of Justice' and is mandatory reading for anyone specializing in contemporary moral theory. Gauthier does two distinct, although closely related, things in his book: (l) he defends a theory of rational choice, and (2) he defends a contractarian theory of morality. The two are (...) related, since on his view moral principles are rational and impartial constraints on the pursuit of self—interest. (shrink)
