Natural properties are those that carve reality at the joints. The notion of carving reality at the joints, however, is somewhat obscure, and is often understood in terms of making for similarity, conferring causal powers, or figuring in the laws of nature. I develop and assess an account of the third sort according to which carving reality at the joints is understood as having the right level of determinacy relative to nomic roles. The account has the attraction of involving very weak metaphysical presuppositions, but fails to capture several features that natural properties are presumed to have.

We defend a version of left-libertarianism, and discuss some of its implications for global justice (and economic justice among nations in particular). Like the better known right-libertarianism, left-libertarianism holds that agents own themselves. Unlike right-libertarianism, left-libertarianism holds that natural resources (land, oil, air, etc.) are owned in some egalitarian sense and can be legitimately appropriated by individuals or groups only when the appropriations are compatible with the specified form of egalitarian ownership. We defend the thesis of self-ownership on the grounds that it is required to protect individuals adequately from interference in their lives by others. We then defend a particular conception of egalitarian ownership of natural resources according to which those who appropriate unappropriated natural resources must pay competitive rent (determined by supply and demand) for the rights that they have claimed. We then go on to apply the principles to issues of global justice. We defend the view that countries owe payments to a global fund for the value of unimproved natural resources that they have appropriated, and that this fund is to be divided on some egalitarian basis among the citizens of the world. We..

We shall focus on moral theories that are solely concerned with promoting the benefits (e.g., wellbeing) of individuals and explore the possibility of such theories ascribing some priority to benefits to those who are worse off—without this priority being absolute. Utilitarianism (which evaluates alternatives on the basis of total or average benefits) ascribes no priority to the worse off, and leximin (which evaluates alternatives by giving lexical priority to the worst off, and then the second worst off, and so on) ascribes absolute priority to the worse off (i.e., favors even a very small benefit to a worse off person over very large benefits to large numbers of better off people). Neither extreme view, we assume, is plausible.

Suppose that time is infinitely long towards the future, and that each feasible action produces a finite amount of utility at each time. Then, under appropriate conditions, each action produces an infinite amount of utility. Does this mean that utilitarianism lacks the resources to discriminate among such actions? Since each action produces the same infinite amount of utility, it seems that utilitarianism must judge all actions permissible, judge all actions impermissible, or remain completely silent. If the future is infinite, that is, the prospects for utilitarianism look bleak

An ethical theory is axiological just in case it makes the permissibility of actions depend solely on considerations of goodness. Act utilitarianism is the paradigm axiological theory. An ethical theory is a pure rights theory just in case it judges an action permissible if and only if it violates no one’s rights. Libertarianism is a paradigm pure rights theory. I shall formulate and defend a type of axiological theory that, unlike act utilitarianism, is sensitive in a new and interesting way to whether rights are violated.Let us start by briefly considering the strengths and weakness of act utilitarianism. Act utilitarianism judges an action permissible just in case it maximizes social welfare. It has many attractive features. It is a clearly formulated theory that draws on the machinery of decision theory. It takes a tough minded approach to morality: always focusing on the outcomes of actions. And it takes human welfare very seriously. The axiological theory I shall defend will have all these features.

Maximizing act consequentialism holds that actions are morally permissible if and only if they maximize the value of consequences—if and only if, that is, no alternative action in the given choice situation has more valuable consequences.1 It is subject to two main objections. One is that it fails to recognize that morality imposes certain constraints on how we may promote value. Maximizing act consequentialism fails to recognize, I shall argue, that the ends do not always justify the means. Actions with maximally valuable consequences are not always permissible. The second main objection to maximizing act consequentialism is that it mistakenly holds that morality requires us to maximize value. Morality, I shall argue, only requires that we satisfice (promote sufficiently) value, and thus leaves us a greater range of options than maximizing act consequentialism recognizes. The issues discussed are, of course, highly complex, and space limitations prevent me from addressing them fully. Thus, the argument presented should be understood merely as the outline of an argument.

We here address the question of how, for a theory of justice, a concern for the promotion of equality can be combined with a concern for making people as well off as possible. Leximin, which requires making the worst off position as well off as possible, is one way of combining a concern for making people’s lives go well with a special concern for those who are especially poorly off. Many egalitarians, however, reject its near-monomaniacal focus on the worst off position (to the exclusion of other poorly off persons). In this paper, we explore the possibility of combining a weak kind of egalitarianism with a weak kind of efficiency requirement in a way that avoids leximin’s obsession with the worst off position. For example, one may consider solving all cases where efficiency is not at issue by choosing the alternative that is most equal according to the Gini-coefficient or some other well-established inequality measure. All standard inequality measures sometimes judge an alternative as more equal than another alternative even though the latter maximizes the benefits of the worst off. Thus it may seem like a promising way of avoiding the leximin approach within an egalitarian framework. Surprisingly, given certain generally accepted assumptions, this turns out to be impossible. The only possible way of combining weak egalitarianism with weak efficiency requires, we shall show, the rejection of a widely accepted—but perhaps dubious—contraction consistency condition on justice or the acceptance of some version of the leximin principle

Under what conditions is it morally permissible to commit suicide, to assist in someone’s suicide, or to kill another person with his/her consent? Under what conditions is it morally permissible to use force to prevent such acts? I shall defend a libertarian answer to these questions. On this view, autonomous agents initially fully own themselves in the same sense that one can fully own an inanimate object such as a car. Just as full owners of cars are morally permitted, under a broad range of conditions, to destroy their cars or have someone else do so, autonomous agents who fully own themselves are permitted, under a broad range of conditions, to terminate their lives or to have someone else do so. Furthermore, under these conditions, other agents are not permitted to use force to prevent a full self-owner’s consensual death. I shall focus on consensual killing (i.e., with the killed person’s consent) of autonomous agents. This includes suicide, assisting with suicide, voluntary euthanasia, and even cases where a non-sick person requests that another kill her. I shall not address cases of killing that are involuntary (against the will of the person killed) or non-voluntary (where the being killed is not autonomous; e.g., killing animals, children, and incapacitated adults). These are important issues, but they cannot be addressed here.

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

Does one have an obligation to keep one’s promises? I answer this question by distinguishing between two broad conceptions of promising. On the normativized conception of promising, a promise is made when an agent validly offers to undertake an obligation to the promisee to perform some act (i.e., give up a liberty-right in relation to her) and the promisee validly accepts the offer. Keeping such promises is morally obligatory by definition. On the non- normativized conception, the nature of promising does not conceptually entail any connection with the obligation to keep promises. A promise might be understood, for example, as an assertion that one will do something along with special assurance that one will do so and an invitation to rely on that assurance. A particularly attractive and relevant non-normativized account of promising takes promising simply to be giving one’s word concerning one’s future conduct. So understood, it is plausible—as a substantive matter—that one has an obligation to (1) alert the promisee, if one realizes that he will not perform the promised action, (2) apologize and compensate the promisee, if one does not perform the action, but one has no obligation to perform the promised action.

In Justice, Luck, and Knowledge, Susan Hurley defends a reason-responsive account of responsibility, argues that appeals to responsibility cannot provide a justification or non-trivial specification of brute luck egalitarian theories of justice, and sketches her own cognitive-bias-neutralizing theory of justice. Throughout, Hurley is concerned with normative (as opposed to causal) responsibility, where this is understood as that which licenses (moral or prudential) praise, blame, and other reactive attitudes and which implies at least partial (substantive) moral accountability in principle for choices and their results. I shall focus on her arguments about the role of responsibility in brute luck egalitarian theories of justice.

The teleological/deontological distinction was introduced in 1930 by C.D. Broad] and since then it has come to be accepted as the fundamental classificatory distinction for moral philosophy. I shall argue that the presupposition that there is a single fundamental classificatory distinction is false. There are too many features of moral theories that matter for that to be so. I shall argue furthermore that as it is usually drawn the teleological/deontological distinction is not even a fundamental distinction. Another distinction, that between theories that make the right depend solely on considerations of goodness (axiological theories) and those that do not, is significantly more important

I formulate and defend a theory of special procreative duties in the context of a liberal egalitarian theory of justice. I argue that (1) the only special duty that procreators owe their offspring is that of ensuring that their life prospects are non-negative (worth living), and (2) the only special duty that procreators owe others is that of ensuring that they are not disadvantaged by the procreators’ offspring (a) violating their rights or (b) adversely affecting their equality rights and duties.

Although Robert Nozick has argued that libertarianism is compatible with the justice of a minimal state—even if does not arise from mutual consent—few have been persuaded. I will outline a different way of establishing that a non-consensual libertarian state can be just. I will show that a state can—with a few important qualifications—justly enforce the rights of citizens, extract payments to cover the costs of such enforcement, redistribute resources to the poor, and invest in infrastructure to overcome market failures.

Child liberationism holds that children are entitled to more freedom from interference than we currently acknowledge socially or legally. It holds, for example, that "the law [should] grant and guarantee to the young the freedom that it now grants to adults to make certain kinds of choices, do certain kinds of things, and accept certain kinds of responsibilities. This means in turn that the law [should] take action against anyone who interferes with young people's rights to do such things".1 Call an agent minimally rational just in case he/she is capable of basic means-ends reasoning and of basic reflection on his/her beliefs and desires. No plausible form of child liberationism advocates full freedom from interference (i.e., as much as normal adults) for children that are not yet minimally rational. Some child liberationists do, however, advocate full freedom from interference for all minimally rational children -- typically those over age 5, say. Call this position radical child libera tionism . Other child liberationists only advocate full freedom from interference for older children -- typically those over age 12, say. Call this position moderate child libera tionism .2 For the sake of argument we shall grant that even young minimally rational children (e.g., 5 year olds) have full rights of non-interference. We shall argue that there are nonetheless a wide range of paternalistic practices regarding such children that are legitimate. In short, even granting the radical child liberationist thesis that young children have the same formal rights to freedom as competent adults, it does not follow that young children should enjoy the same effective freedom. Indeed, there are good reasons for holding that they should enjoy less freedom. Or so we shall..

David Gauthier's Morals by Agreement is the most complete and suggestive contractarian theory of morality since the work of Rawls. In this anthology a number of prominent moral and political philosophers offer a critical assessment of Gauthier's theory and its three main projects: developing a contractarian foundation for morality, defending a theory of rational choice, and supporting the claim that rationality requires one to keep one's agreements. An introduction sets out Gauthier's project, while Gauthier himself has the last word, responding to the critiques. This collection will interest moral and political philosophers, social theorists, and specialists in the philosophy and theory of law as well as management sciences.

John Locke (1690), libertarians, and others have held that agents are self-owners in the sense that they have private property rights over themselves in the same way that people can have private property rights over inanimate objects. This private ownership is typically taken to include (1) control rights over (power to grant and deny permission for) the use of their persons (e.g., what things are done to them), (2) rights to transfer the rights they have to others (by sale, rental, gift, or loan), and (3) tax immunities for the possession and exercise of these rights (so that, unlike renters, for example, they owe no payment for these rights). The property rights in question are moral rights, and need not be legally recognized. Thus, a country that allows involuntary slavery fails to recognize the (moral) self-ownership of the slaves.
