Most philosophers assume that ‘ought’ implies ‘can’, and most of them hold that this principle is true not only universally but also analytically or conceptually. Some skeptics deny this principle, although they often admit some related one. In this article, we show how new empirical evidence bolsters the skeptics’ arguments. We then defend the skeptical view against some objections to the empirical evidence and to its effect on the traditional principle. In light of the new evidence, we conclude that philosophers (...) should stop unconditionally assuming that ‘ought’ implies ‘can’. (shrink)

In Abortion and Infanticide, Michael Tooley argues that it is not wrong to destroy potential persons, such as fetuses and newly born infants. His argument presupposes the following: 1)that the destruction of potential persons is not directly wrong because potential persons do not have a right to life; 2)that destroying a potential person—a fetus or an infant—is morally the same as preventing the existence of an possible person by, for example, using a contraceptive or refraining from, intercourse during a woman's (...) fertile period; and 3)that it is not wrong to prevent the existence of additional persons who are likely to lead happy or satisfying lives. Here I am concerned with the third presupposition. On this presupposition, the prima facie permissibility of abortion and infanticide hinges on the “moral neutrality” of those of our reproductive decisions on which the existence of additional people depends.

Controversies about time discounting loom large in decisions about climate change. Prominently, a particularly controversial debate about time discounting in climate change decision-making has been conducted within climate economics, between the authors of Stern et al. and their critics :977–981, 2006; Weitzman in J Econ Lit XLV:703–724, 2007; Nordhaus in J Econ Lit XLV:686–702, 2007). The article examines the role of values in this debate. Firstly, it is shown that time discounting is a case in which values are key because (...) it is at heart an ethical problem. Secondly, it is argued that time discounting in climate economics is a case of economists making frequent and routine references to ethical values and indeed conduct ethical debates with each other. Thirdly, it is argued that there is evidence for deep and pervasive entanglement between facts and values in the prevalent methodologies for time discounting. Finally, it is argued that this means that economists have given up the ‘value-free ideal’ concerning time discounting, and discussed how the current methodology of time discounting in economics can be improved.

On the received view, the Representational Theory of Measurement reduces measurement to the numerical representation of empirical relations. This account of measurement has been widely criticized. In this article, I provide a new interpretation of the Representational Theory of Measurement that sidesteps these debates. I propose to view the Representational Theory of Measurement as a library of theorems that investigate the numerical representability of qualitative relations. Such theorems are useful tools for concept formation that, in turn, is one crucial aspect (...) of measurement for a broad range of cases in linguistics, rational choice, metaphysics, and the social sciences.

As diachronic agents, we deliberate and decide in the present to perform future courses of action. Such future‐directed decisions normally enjoy a distinctive species of rational authority over subsequent thought and action. But what is the nature of this authority, and what underwrites its normative force? In this paper, I argue that our answer to this question must begin by situating future‐directed deciding within an intrapersonal model of cross‐temporal influence. The role of future‐directed deciding (and intending), then, is not to (...) generate a novel decision‐based reason for action, but instead to preserve a certain positive normative status over time. I develop an entitlement approach to decisional authority, according to which an agent who rationally decides to ϕ enjoys a practical entitlement, rather than a reason‐based practical justification, to ϕ at the appointed time. This entitlement is underwritten, I argue, by the warrant‐preserving nature of the sequence taking an agent from deliberation to subsequent action. (shrink)

This paper explores the implications of extended and distributed cognition theory for our notions of personal identity. On an extended and distributed approach to cognition, external information is under certain conditions constitutive of memory. On a narrative approach to personal identity, autobiographical memory is constitutive of our diachronic self. In this paper, I bring these two approaches together and argue that external information can be constitutive of one’s autobiographical memory and thus also of one’s diachronic self. To develop this claim, (...) I draw on recent empirical work in human-computer interaction, looking at lifelogging technologies in both healthcare and everyday contexts. I argue that personal identity can neither be reduced to psychological structures instantiated by the brain nor by biological structures instantiated by the organism, but should be seen as an environmentally-distributed and relational construct. In other words, the complex web of cognitive relations we develop and maintain with other people and technological artifacts partly determines our self. This view has conceptual, methodological, and normative implications: we should broaden our concepts of the self as to include social and artifactual structures, focus on external memory systems in the (empirical) study of personal identity, and not interfere with people’s distributed minds and selves.

The desire-satisfaction theory of well-being says, in its simplest form, that a person’s level of welfare is determined by the extent to which their desires are satisfied. A question faced by anyone attracted to such a view is, *Which desires*? This paper proposes a new answer to this question by characterizing a distinction among desires that isn’t much discussed in the well-being literature. This is the distinction between what a person wants in a merely behavioral sense, in that the person (...) is, for some reason or other, disposed to act so as to try to get it, and what a person wants in a more robust sense, the sense of being *genuinely attracted* to the thing. I try to make this distinction more clear, and I argue for its axiological relevance by putting it to work in solving four problem cases for desire satisfactionism. The theory defended holds that only desires in the latter, genuine-attraction sense are relevant to welfare. (shrink)

One of the leading approaches to the nature of sensory pleasure reduces it to desire: roughly, a sensation qualifies as a sensation of pleasure just in case its subject wants to be feeling it. This approach is, in my view, correct, but it has never been formulated quite right; and it needs to be defended against some compelling arguments. Thus the purpose of this paper is to discover the most defensible formulation of this rough idea, and to defend it against (...) the most interesting objections. (shrink)

The desire-satisfaction theory of welfare says, roughly, that one's life goes well to the extent that one's desires are satisfied. On standard 'actualist' versions of the theory, it doesn't matter what you desire. So long as you are getting what you actually want – whatever it is – things are going well for you. There is widespread agreement that these standard versions are incorrect, because we can desire things that are bad for us -– in other words, because there are (...) 'defective desires'. The aim of this paper is to defend the actualist desire-satisfaction theory against the problem of defective desires. I aim to show how the theory can accommodate the obvious fact that we can desire things that are bad for us. Admittedly, there are kinds of allegedly defective desire the theory cannot accommodate, but these desires, I argue, turn out not to be defective in the relevant way. (shrink)

According to the argument from self-sacrifice, standard, unrestricted desire-based theories of welfare fail because they have the absurd implication that self-sacrifice is conceptually impossible. I attempt to show that, in fact, the simplest imaginable, completely unrestricted desire-based theory of well-being is perfectly compatible with the phenomenon of self-sacrifice – so long as the theory takes the right form. I go on to consider a new argument from self-sacrifice against this simple theory, which, I argue, also fails. I conclude that, contrary (...) to popular opinion, considerations of self-sacrifice do not pose a problem for preferentist theories of welfare. (shrink)

This essay discusses monism and pluralism about two related evaluative notions: welfare, or what makes people better off, and value simpliciter, or what makes the world better. These are stipulatively referred to as 'axiological value'. Axiological value property monists hold that one of these notions is reducible to the other (or else eliminable), while axiological value property pluralists deny this. Substantive monists about axiological value hold that there is just one basic kind of thing that makes our lives or the (...) world better, while substantive pluralists hold that there is more than one such thing. A more radical kind of pluralism holds that each of the plurality of good things is good in its own way, thus raising questions concerning value comparability and compensability. The essay elucidates these theories and discusses important arguments for and against them. (shrink)

Kevin Sauvé has recently argued in this journal that David Gauthier's conception of ‘morals by agreement’ is inimical to the development of long-term productive investment and sustainable levels of resource exploitation. According to Sauvé, this is because society is confronted with an intergenerational interaction problem whose strategic equilibrium is suboptimal. However, unlike the ‘contemporaneous Prisoner's Dilemma’ that Gauthier analyzes, the intergenerational version cannot be solved by an appeal to constrained maximization. As a result, Sauvé claims, Gauthier cannot effectively address the (...) question of intergenerational justice.The portion of Sauvé's argument that concerns me is the following:Gauthier solves the contemporaneous Prisoner's Dilemma by ensuring that each person will cooperate only if all others cooperate, and indeed his conception of morality is aimed at ensuring that all individuals incur the costs as well as the benefits of social cooperation. But the contemporaneous solution cannot be applied to the Intergenerational Dilemma: if each generation will save for the next only if the previous generations have also saved, none will ever save.

Hedonism and the desire-satisfaction theory of welfare are typically seen as archrivals in the contest over identifying what makes one's life go best. It is surprising, then, that the most plausible form of hedonism just is the most plausible form of desire satisfactionism. How can a single theory of welfare be a version of both hedonism and desire satisfactionism? The answer lies in what pleasure is: pleasure is, in my view, the subjective satisfaction of desire. This thesis about pleasure is (...) clarified and defended only after we proceed through the dialectics that get us to the most plausible forms of hedonism and desire satisfactionism. (shrink)

ABSTRACT:This paper examines the norms that should guide policies aimed at promoting happiness or, more broadly, well-being. In particular, we take up the question of which conception of well-being should govern well-being policy, assuming some such policies to be legitimate. In answer, we lay out a case for ‘pragmatic subjectivism’: given widely accepted principles of respect for persons, well-being policy may not assume any view of well-being, subjectivist or objectivist. Rather, it should promote what its intended beneficiaries see as good (...) for them: pleasure for hedonists, excellence for Aristotelians, etc. Specifically, well-being policy should promote citizens’ ‘personal welfare values’: those values—and not mere preferences—that individuals see as bearing on their well-being. Finally, we briefly consider how pragmatic subjectivism works in practice. While our discussion takes for granted the legitimacy of well-being policy, we suggest that pragmatic subjectivism strengthens the case for such policy. (shrink)

It may even be held that [the intellect] is the true self of each, inasmuch as it is the dominant and better part; and therefore it would be a strange thing if a man should choose to live not his own life but the life of some other than himself. Moreover . . . that which is best and most pleasant for each creature is that which is proper to the nature of each; accordingly the life of the intellect is (...) the best and the pleasantest life for man, inasmuch as the intellect more than anything else is man.

The so-called Buddhist momentarists, such as Dharmakīrti and his followers, defend the momentariness of all things. However, with equal force they also defend the persistence of all things, not just within a single lifetime but over an indefinite cycle of rebirth. Naturally, they have an interesting theory of persistence, according to which things persist without being self-identical over time. The theory is best presented in the Lokāyatāparīkṣā chapter of Śāntarakṣita’s Tattvasaṃgraha and Kamalaśīla’s Paṅjikā, as they clearly articulate the criteria of (...) persistence without identity. The purpose of this paper is to formulate a Buddhist theory of persistence through the analysis of these texts. Here is the basic formula: Things persist as series, which is constituted by momentary entities that are causally related as upādāna and upādeya. Upādāna causal relation is demarcated from other causal relations by the principle of changeability with temporal restriction, and the principle adopts further qualifications to accommodate complex cases and personal persistence. I have addressed a problem that contemporary physicalism might pose a threat to the Buddhist account of personal persistence, and argued that the problem can be evaded by regarding persons as psycho-physical entities rather than strictly non-physical. In its general outlook, the Buddhist theory of persistence is close to Theodore Sider’s stage theory in that persistence is a matter of distinct individuals standing in a special causal relationship. As regards personal persistence, the Buddhist has a stricter condition than Parfit’s IDM thesis, which states that psychological connectedness with any cause is what matters for survival. The Buddhist would say it is moral connectedness with a special cause called upādāna. (shrink)

Closest-continuer or best-candidate accounts of persistence seem deeply unsatisfactory, but it’s hard to say why. The standard criticism is that such accounts violate the ‘only a and b’ rule, but this criticism merely highlights a feature of the accounts without explaining why the feature is unacceptable. Another concern is that such accounts violate some principle about the supervenience of persistence facts upon local or intrinsic facts. But, again, we do not seem to have an independent justification for this supervenience claim. (...) Instead, I argue that closest continuer accounts are committed to unexplained correlations between distinct existences, and that this is their fundamental flaw. We can have independent justification for rejecting such correlations, but what the justification is depends upon much broader issues in ontology. There is no one-size-fits all objection to closest-continuer accounts of persistence. (shrink)

The tenuous claims of cost-benefit analysis to guide policy so as to promote welfare turn on measuring welfare by preference satisfaction and taking willingness-to-pay to indicate preferences. Yet it is obvious that people's preferences are not always self-interested and that false beliefs may lead people to prefer what is worse for them even when people are self-interested. So welfare is not preference satisfaction, and hence it appears that cost-benefit analysis and welfare economics in general rely on a mistaken theory of (...) well-being. This essay explores the difficulties, criticizes standard defences of welfare economics, and then offers a new partial defence that maintains that welfare economics is independent of any philosophical theory of well-being. Welfare economics requires nothing more than anevidentialconnection between preference and welfare: in circumstances in which people are concerned with their own interests and reasonably good judges of what will serve their interests, their preferences will be reliable indicators of what is good for them.

Altruistic self-sacrifice is rare, supererogatory, and not to be expected of any rational agent; but, the possibility of giving up one's life for the common good has played an important role in moral theorizing. For example, Judith Jarvis Thomson (2008) has argued in a recent paper that intuitions about altruistic self-sacrifice suggest that something has gone wrong in philosophical debates over the trolley problem. We begin by showing that her arguments face a series of significant philosophical objections; however, our project (...) is as much constructive as critical. Building on Thomson's philosophical argument, we report the results of a study that was designed to examine commonsense intuitions about altruistic self-sacrifice. We find that a surprisingly high proportion of people judge that they should give up their lives to save a small number of unknown strangers. We also find that the willingness to engage in such altruistic self-sacrifice is predicted by a person's religious commitments. Finally, we show that folk-moral judgments are sensitive to agent-relative reasons in a way that diverges in important ways from Thomson's proposed intuitions about the trolley problem. With this in mind, we close with a discussion of the relative merits of folk intuitions and philosophical intuitions in constructing a viable moral theory. (shrink)

The health gradient among those who are by historical standards both remarkably healthy and well-off is of considerable moral importance with respect to benevolence, justice and the theory of welfare. Indeed it may help us to realize that for most people the good life lies in close and intricate social ties with others which can flourish only when inequalities are limited. The health gradient suggests that there is a story to be told in which egalitarian justice, solidarity, health and well-being (...) go hand-in-hand. (shrink)

Poverty indexes are essential for monitoring poverty, setting targets for poverty reduction, and tracking progress on these goals. This paper suggests that further justification is necessary for using the main poverty indexes in the literature in any of these ways. It does so by arguing that poverty should not decline with the mere addition of a rich person to a population and showing that the standard indexes do not satisfy this axiom. It, then, suggests a way of modifying these indexes (...) to avoid this problem. (shrink)

In a number of papers, including the one published in this journal, Robert Sparrow has mounted attacks on consequentialism using principally what he takes to be an important fact, which he believes constitutes a reductio ad absurdum of consequentialism in its many forms and of this author's approach to enhancement and disability in particular (see page 276). This fact is the current longer life expectancy of women when compared with men. Here the author argues that Sparrow's arguments and entire approach (...) utterly fail. In doing so the author hopes to shed further light on the role of normalcy, normal species functioning and species-typical functioning in debates about enhancement and disability. (shrink)

This article explores the defense Indian Buddhist texts make in support of their conceptions of lives that are good for an individual. This defense occurs, largely, through their analysis of ordinary experience as being saturated by subtle forms of suffering . I begin by explicating the most influential of the Buddhist taxonomies of suffering: the threefold division into explicit suffering , the suffering of change , and conditioned suffering . Next, I sketch the three theories of welfare that have been (...) most influential in contemporary ethical theory. I then argue that Buddhist texts underdetermine which of these theories would have been accepted by ancient Indian Buddhists. Nevertheless, Buddhist ideas about suffering narrow the shape any acceptable theory of welfare may take. In my conclusion, I argue that this narrowing process itself is enough to reconstruct a philosophical defense of the forms of life endorsed in Buddhist texts. (shrink)

It appears that utilitarian arguments in favor of moral vegetarianism cannot justify a complete prohibition of eating meat. This is because, in certain circumstances, forgoing meat will prevent no pain, and so, on utilitarian grounds, we should be opportunistic carnivores rather than moral vegetarians. In his paper, ‘Puppies, pigs, and people: Eating meat and marginal cases,’ Alastair Norcross argues that causal impotence arguments like these are misguided. First, he presents an analogous situation, the case of chocolate mousse a-la-bama, in order (...) to argue that we, individually, are not causally impotent. Second, Norcross offers a threshold argument in which he argues that while we may individually be causally impotent, when we adopt moral vegetarianism in concert with others, we become causally potent in preventing harms by factory farming. We argue that Norcross's responses ultimately fail to address the causal impotence objection. The former argument fails because it vastly oversimplifies the world in which we find ourselves. Given the size of factory farming, the reasonable conclusion is that we are in fact powerless to prevent harms to animals in factory farms in many or most cases. The latter argument fails because even if collective action will have an impact on factory farming, this does not provide us with an argument against being carnivores in certain circumstances.

In this essay several challenges are raised to the project of classifying Śāntideva’s ethical reasoning given in his Bodhicaryāvatāra, or Guide to the Way of the Bodhisattva, as a species of ethical theory such as consequentialism or virtue ethics. One set of difficulties highlighted here arises because Śāntideva wrote this text to act as a manual of psychological transformation, and it is therefore often difficult to determine when his statements indicate his own ethical views. Further, even assuming we can identify (...) a set of statements that accurately portray the moral position of Śāntideva, it is argued that these statements underdetermine which foundational normative theory should be ascribed to him.

Our ability to tell stories about ourselves has captivated many theorists, and some have taken these developments for an opportunity to answer long-standing questions about the nature of personhood. In this essay I employ two skeptical arguments to show that this move was a mistake. The first argument rests on the observation that storytelling is revisionary. The second implies that our stories about ourselves are biased in regard to our existing self-image. These arguments undercut narrative theories of identity, but they (...) leave room for a theory of narrative self-knowledge. The theory accommodates the first skeptical argument because there are event descriptions with retrospective assertibility conditions, and it accommodates the second argument by denying us epistemic privilege in regard to our own past. The result is that we do know our past through storytelling, but that it is a contingent feature of some of our stories that they are about ourselves. (shrink)

We use “I’ll be glad I did it” reasoning all the time. For example, last night I was trying to decide whether to work on this paper or go out to a movie. I realized that if I worked on the paper, then today I would be glad I did it. Whereas, if I went out to the movie, today I would regret it. This enabled me to see that I should work on the paper rather than going out to (...) a movie. This looks like excellent reasoning: Paper argument: 1. If I work on my paper, I’ll be glad I did it. 2. Therefore, I should work on my paper. When we’re having trouble making a big life decision, we often try to picture what will happen each way we might choose, and imagine how we’ll feel in that outcome. When choosing between two jobs, we might use this reasoning. Suppose you are choosing between two jobs and you know quite a lot about what the two jobs will be like. In one, you will make a lot of money but have to work eighty-hour weeks and see little of your family. In the other, you will make considerably less money—though enough to support yourself and your family. You’ll have much more time for your family. The money is attractive. But overall, you realize you’ll be glad to have the time with your family if you take the second job—you’ll be glad you made that choice. It seems this is a good way of realizing that you should take the second job. (shrink)

It seems that if abortion is permissible, then stem cell research must be as well: it involves the death of a less significant thing (an embryo rather than a fetus) for a greater good (lives saved rather than nine months of physical imposition avoided). However, I argue in this essay that this natural thought is mistaken. In particular, on the assumption that embryos and fetuses have the full moral status of persons, abortion is permissible but one form of stem cell (...) research is notFthe practice of creating embryos and then destroying them to extract cell..

In Responding to Global Poverty, Christian Barry and Gerhard Øverland argue that, while exploitation is morally problematic, responsibilities not to exploit are characteristically less stringent than responsibilities not to harm. They even suggest that exploiters’ responsibilities to assist the exploited may be weaker than the responsibilities of culpable bystanders who are able to help the poor but fail to do so We think Barry and Øverland underestimate the prospects of the exploitation argument. In our paper, we suggest that exploitation can (...) plausibly be understood as a kind of harm. If exploitation harms, then it requires special justification and can generate stringent responsibilities not to exploit that have a different ground than those generated by morally culpable failures to assist. This suggests an important way to rehabilitate arguments for poverty relief on the basis of a duty not to harm, and that there is more interesting territory to explore than Barry and Øverland’s arguments suggest.

The non-identity problem concerns actions that affect who exists in the future. If such an action is performed, certain people will exist in the future who would not otherwise have existed: they are not identical to any of the people who would have existed if the action had not been performed. Some of these actions seem to be wrong, and they seem to be wrong in virtue of harming the very future individuals whose existence is dependent on their having been (...) performed. The problem arises when it is argued that the actions do not harm these people—because the actions do not make them worse off than they would otherwise be.1 Consider: Radioactive Waste Policy: We are trying to decide whether to adopt a permissive radioactive waste policy. This policy would be less inconvenient to us than our existing practices. If we enact the newly-proposed policy, then we will cause there to be radioactive pollution that will cause illness and suffering. However, the policy will have such significant effects on public policy and industry functioning, that different people will exist in the future depending on whether we enact the policy. Two things should be emphasized. First, the illness and suffering caused will be very serious: deformed babies, children with burns from acid rain, and adults dying young from cancer. Second, the policy will affect who will exist in the future because our present practices invade people’s everyday lives, for example by affecting recycling practices in the home; these practices will change if the policy is adopted. Furthermore, whether we adopt the policy will determine which plants are built where, what jobs are available, and what trucks are on the road. These effects will create small differences in everyone’s lives which ultimately affect who meets whom and who conceives with whom, or at least when people conceive. This affects who exists in the future. (shrink)

ABSTRACTDemandingness objections to consequentialism often claim that consequentialism underestimates the moral significance of the stranger/special other distinction, mistakenly extending to strangers demands it is proper for special others to make on us, and concluding that strangers may properly demand anything of us if it increases aggregate goodness. This argument relies on false assumptions about our relations with special others. Boundaries between ourselves and special others are both a common and a good-making feature of our relations with them. Hence, demandingness objections (...) that rely on the argument in question fail. But the same observations about our relations with special others show that there are many demands special others may not properly make, and since we cannot be more guilty of unjustified partiality in insisting on boundaries between ourselves and strangers than on boundaries between ourselves and special others, there are – as demandingness objections maintain – some demands strangers may not properly make on us.

Should we be time-biased on behalf of other people? ‘Sometimes yes, sometimes no’—it is tempting to answer. But this is not right. On pain of irrationality, we cannot be too selective about when we are time-biased on behalf of other people.

The typical function of goals is to regulate action in a way that furthers goal achievement. Goals are typically set on the assumption that they will help bring the agent closer to the desired state of affairs. However, sometimes endorsement of a goal, or the processes by which the goal is set, can obstruct its achievement. When this happens, the goal is self-defeating. Self-defeating goals are common in both private and social decision-making but have not received much attention by decision (...) theorists. In this paper, we investigate different variants of three major types of self-defeating mechanisms: The goal can be an obstacle to its own fulfilment, goal-setting activities can impede goal achievement, and disclosure of the goal can interfere with its attainment. Different strategies against self-defeasance are tentatively explored, and their efficiency against different types of self-defeasance is investigated. (shrink)

If A is better than B and B is better than C, then A is better than C, right? Larry Temkin and Stuart Rachels say: No! Betterness is nontransitive, they claim. In this paper, I discuss the central type of argument advanced by Temkin and Rachels for this radical idea, and argue that, given this view very likely has sceptical implications for practical reason, we would do well to identify alternative responses. I propose one such response, which employs the idea (...) that rational agents might regard some options as incommensurate in value, and will reasonably employ a heuristic of status quo maintenance to avoid suboptimal choices from incommensurate goods.

The prescriptive has both an objective and a subjective interpretation. In the objective sense, what one ought to do depends on what is actually true. In the subjective sense it depends on what one believes to be true. Ordinary usage seems to vacillate between these two interpretations. An example (the indecisive terrorist) is used to show that a subjective ought statement can have a determinate truth-value in situations where the corresponding objective ought statement has no truth-value, not even an unknowable (...) one. Therefore the subjective ought is not definable in terms of the objective ought. However, definability in the other direction is not excluded by this argument. (shrink)

Do we love for reasons? It can seem as if we do, since most cases of non‐familial love seem *selective*: coming to love a non‐family‐member often begins with our being drawn to them for what they are like. I argue, however, that we can vindicate love's selectivity, even if we maintain that there are no reasons for love; indeed, that gives us a simpler, and hence better, explanation of love's selectivity. We don't, in short, come to love *for* reasons. That (...) which seemed like evidence for thinking that there are reasons for love, then, turns out to militate against that view: how can these purported reasons be reasons for love, if they don't engender (in virtue of rationalizing) it?

We know that Homo sapiens will not exist forever. Given this, how should our species end? What are the reasons, if any, to delay our extinction? In this paper, I show that the pre-eminent reasons which favour prolonging the existence of the species are partial: they will arise from the particular attachments and projects of the final few generations. While there may also be impartial reasons to prolong the species, these reasons are liable, with time, to reverse their valence: we (...) can be reasonably confident that they will ultimately recommend hastening the demise of the species. Consequently, it is likely that our descendants will eventually face a difficult -- possibly tragic -- conflict, between partial duties that recommend living on, and an impartial duty to extinguish the species.

What difference does it make to matters of value, for a desire satisfactionist, if a given desire is *absent*, rather than *present*? I argue that it is most plausible to hold that the state in which a given desire is satisfied is, other things being equal, incommensurate with the state in which that desire does not exist at all. In addition to illustrating the internal attractions of the view, I demonstrate that this idea has attractive implications for population ethics. Finally, (...) I show that the view is not subject to John Broome's `greedy neutrality' worry. (shrink)

Economic approaches to both social evaluation and decision-making are typically Paretian or utilitarian in nature and so display commitments to both welfarism and consequentialism. The contrast between the economic approach and any rights-based social philosophy has spawned a large literature that may be divided into two branches. The first is concerned with the compatibility of rights and utilitarianism seen as independent moral forces. This branch of the literature may be characterized as an example of the broader debate between the teleological (...) and deontological approaches. The second is concerned with the possibility that substantial rights may be grounded in utilitarianism with the moral force of rights being derived from more basic commitments to welfarism and consequentialism. This branch of the literature may be characterized as an exploration of the flexibility of the teleological approach, and, in particular, its ability to give rise to views more normally associated with the deontological approach. This essay is concerned with the second branch of the literature. (shrink)

Recent scientific advances in the field of gene editing have led to a renewed discussion on the moral acceptability of human germline modifications. Gene editing methods can be used on human embryos and gametes in order to change DNA sequences that are associated with diseases. Modifying the human germline, however, is currently illegal in many countries but has been suggested as a ‘last resort’ option in some reports. In contrast, preimplantation genetic diagnosis is now a well-established practice within reproductive medicine. (...) Both methods can be used to prevent children from being born with severe genetic diseases. This paper focuses on four moral concerns raised in the debate about germline gene editing and applies them to the practice of PGD for comparison: Violation of human dignity, disrespect of the autonomy and the physical integrity of the future child, discrimination of people living with a disability and the fear of slippery slope towards immoral usage of the technology, e.g. designing children for specific third party interests. Our analysis did not reveal any fundamental differences with regard to the four concerns. We argue that with regard to the four arguments analyzed in this paper germline gene editing should be considered morally as acceptable as the selection of genomes on the basis of PGD. However, we also argue that any application of GGE in reproductive medicine should be put on hold until thorough and comprehensive laws have been implemented to prevent the abuse of GGE for non-medical enhancement.

The agent-relative/agent-neutral distinction is one of the most important in contemporary moral theory. Yet, providing an adequate formal account of it has proven difficult. In this article I defend a new formal account of the distinction, one that avoids various problems faced by other accounts.

The principle of beneficence directs healthcare practitioners to promote patients’ well-being, ensuring that the patients’ best interests guide treatment decisions. Because there are a number of distinct theories of well-being that could lead to different conclusions about the patient’s good, a careful consideration of which account is best suited for use in the medical context is needed. While there has been some discussion of the differences between subjective and objective theories of well-being within the bioethics literature, less attention has been (...) given to the questions of what work a theory of well-being needs to do in bioethics and which standards of success ought to be used in selecting a theory of well-being for use in medicine. In this article, I argue that traditional theories of well-being developed in philosophy are not well suited to meet the needs of the medical context. For the principle of beneficence to be most useful, the underlying account of well-being should satisfy two conditions: first, it needs to lead to a concrete, action-guiding determination of the patient’s good; and, second, any recommendations it offers need to be justifiable to patients. Standard accounts of well-being have difficulty satisfying both conditions. Exploring the limitations of these theories when applied to treatment dilemmas helps point the way toward the development of an account of well-being better suited to healthcare. (shrink)
