According to the Asymmetry, it is wrong to bring a miserable child into existence but permissible not to bring a happy child into existence. When it comes to procreation, we don’t have complete procreative liberty. But we do have some discretion. The Asymmetry seems highly intuitive. But a plausible account of the Asymmetry has been surprisingly difficult to provide, and it may well be that most moral philosophers – or at least most consequentialists – think that all reasonable efforts to (...) provide such an account have by now been exhausted. In this paper, I argue that, despite the difficulties, the Asymmetry is too important to be set aside. I also note a handful of accounts of the Asymmetry that have been proposed and why they fail. It seems, for example, that it will not do to say that some people matter morally and others don’t, or that a person matters morally in some worlds but not others. My own conclusion is that, while we are bound to say all people matter morally – you, me and the merely possible – we are not bound to say that all their losses– or all ours– matter morally. We can instead distinguish between morally significant and insignificant losses, with the distinction between the two being a matter of where the loss is incurred in relation to the person who incurs it. This way of looking at things – which I call Variabilism– provides the basis for a plausible account of the Asymmetry. The availability of such an account suggests, I think, that our prospects for rescuing the Asymmetry are bright. (shrink)

This book aims to give an account, called Variabilism, of the moral significance of merely possible persons and to use Variabilism to illuminate abortion. In doing so it lays the groundwork for a more productive discussion on abortion.

Child Versus Childmaker investigates a "person-affecting" approach to ethical choice. A form of consequentialism, this approach is intended to capture the idea that agents ought both do the most good that they can and respect each person as distinct from each other. Focusing on cases in which a conflict of interest arises between "childmakers"—parents, infertility specialists, embryologists, and others engaged in the task of bringing new people into existence—and the children they aim to create, the author considers what we today (...) owe those who will come into existence tomorrow.

The Asymmetry consists of two claims. (A) That a possible person's life would be abjectly miserable –less than worth living – counts against bringing that person into existence. But (B) that a distinct possible person's life would be worth living or even well worth living does not count in favour of bringing that person into existence. In recent years, the view that the two halves of the Asymmetry are jointly untenable has become increasingly entrenched. If we say all persons matter (...) morally whether they exist or not and on that basis try to explain the first half of the Asymmetry, we lose the second half of the Asymmetry. If we say that some persons do not matter morally and some do and on that basis try to explain the second half of the Asymmetry, we lose the first half of the Asymmetry – or else find ourselves with a principle that is either inconsistent or otherwise deeply troubled in some way that has nothing to do with the content of the Asymmetry itself. In this article, I propose an alternative approach to the Asymmetry which I will call Variabilism. By understanding each and every person, whether existing or not, to matter morally but variably– such that the moral significance of any loss incurred by any person is considered to depend, not on who incurs that loss and whether that person matters morally, but rather on where that loss is incurred in relation to the person who incurs it – we can both nicely ground the two halves of the Asymmetry and avoid the conceptual difficulties that have plagued competing approaches.

ABSTRACT Broome and others have argued that it makes no sense, or at least that it cannot be true, to say that it is better for a given person that he or she exist than not. That argument can be understood to suggest that, likewise, it makes no sense, or at least that it cannot be true, to say that it is worse for a given person that he or she exist than that he or she never have existed at (...) all. This argument is of critical importance to the question of whether consequentialist theory should take a traditional, aggregative form or a less conventional, person‐affecting, or person‐based, form. I believe that, potentially, the argument represents a far more serious threat to the person‐based approach than does, for example, Parfit's two medical programmes example. Parfit's example nicely illustrates the distinction between aggregative and person‐based approaches and raises important questions. But the example — though not, I think, by Parfit — is sometimes pressed into service as a full‐fledged counterexample against the person‐based approach. As such, I argue, the example is not persuasive. In contrast, the Broomeian argument, if correct, is definitive. For that argument relies on certain metaphysical assumptions and various uncontroversial normative claims — and hence nicely avoids putting into play the controversial normative claims that lie at the very heart of the debate. The purpose of the present paper, then, is to evaluate the Broomeian argument. I argue that this potentially definitive challenge to a person‐based approach does not in fact succeed. (shrink)

When her baby was born last June, Rossana Dalla Corte, age sixty-two, was thought to be the oldest woman ever to have given birth. Her pregnancy was achieved at a private fertility clinic in Italy, the same clinic that treated “Jennifer F.,” a London woman who, on Christmas day, 1993, at the age of fifty-nine, gave birth to twins. The reproductive procedure, likely to become more common during the next few years, has received intense scrutiny from health officials in Great (...) Britain, France, and Italy. Moral questions concerning that procedure already have been taken up by the popular press in the United States. Such questions can be expected to take on a new urgency as the United States considers reshaping its health care system and, specifically, the circumstances under which coverage for infertility treatment will be provided.

The non-identity problem is really a collection of problems having distinct logical features. For that reason, non-identity problems can be typed. This article focuses on just one type of non-identity problem, the problem, which includes Derek Parfit's depletion example and many others. The can't-expect-better problem uses an assessment about the low probability of any particular person's coming into existence to reason that an earlier wrong act does not harm that person. This article argues that that line of reasoning is unusually (...) treacherous in that it makes not just one hard-to-detect error in what is done with the relevant probability assessments but rather alternates between two. We sort out one fallacy only to fall, against all odds (as it were), into a second. By avoiding both errors, we become able to discern harm in cases in which the can't-expect-better problem argues there is none. We will then be in a position to set aside the can't-expect-better problem as an objection against the person-based intuition that acts that are must be at least some existing or future person.

This article critically examines some of the inconsistency objections that have been put forward by John Broome, Larry Temkin and others against the so-called "person-affecting," or "person-based," restriction in normative ethics, including "extra people" problems and a version of the nonidentity problem from Kavka and Parfit. Certain Pareto principles and a version of the "mere addition paradox" are discussed along the way. The inconsistencies at issue can be avoided, it is argued, by situating the person-affecting intuition within a non-additive form (...) of maximizing consequentialism – a theory which then competes with such additive, or aggregative, forms of maximizing consequentialism as "totalism" and "averagism.".

This collection of essays investigates the obligations we have in respect of future persons, from our own future offspring to distant future generations.

This paper considers two objections based in axiological considerations against the position that whether a given outcome, or possible future or world, is morally worse than a second world may depend in part on what is going on at a third world. Such a wide-angled approach to determining worseness is critical to the solution I have previously proposed in connection with the nonidentity problem. I argue that both objections fail.

David lewis has argued that--Despite the 'fission' cases--One may consistently hold both that what matters in survival is "mental continuity and connectedness" and that what matters in survival is identity. To prove his point, He produces a certain theory of persons. Derek parfit and penelope maddy have objected that the theory lewis produces does not actually have the advantages he claims for it. In this paper, The author questions their objections, And then argues that, Even though lewis's theory has many (...) virtues, No sufficiently knowledgeable person can be justified in accepting it (here and now) as an adequate theory of persons.

Lawyers and philosophers have found it challenging to construct an account of when an act causes harm that is broad enough to address multiple agent problems but not so broad that it fails to distinguish between genuinely harming a person and imposing a condition on a person that we deem undesirable. Thus, we may think an act causes harm only if it makes a difference to a person and, more specifically, makes things worse for that person. If the effect is (...) the same whatever the one agent does in virtue of what a second agent does or is prepared to do, it may seem that what the one agent does makes no difference. Multiple agent problems are endemic. Legal hypotheticals include the example of two fires, each ‘tortiously’ set, converging on a single barn. The physician faces a multiple agent problem when he or she understands that refusing to provide the fertility treatment a patient demands will just lead to another physician providing the treatment instead. And corporations face the problem when they project that conscientiously refraining from drilling for oil at a particular site will not safeguard that site but rather open the door to equally deleterious activities of still other corporations. This paper argues that a useful first step in developing an account of harm in the multiple agent context is to recognize that often, even if the individual agent cannot make things better for a person, the group can. It seems, however, that a fully adequate account will also show how and when the harm that the group imposes on a person devolves to the agent. This paper proposes such an account. Requirements include: that the agent is a member of a group implicated in the harm; that the agent participate in the bringing about of that harm; and that the agent’s non-participation would not have made things worse for the person. To avoid the charge of harm, then, and still participate in the harm that is done by the group, the agent’s participation must make things better for the person; simply not making things worse, once the other conditions are satisfied, is not enough to avoid the charge of harm. Advantages of the proposed account include its ability to discern as an exception cases in which the agent’s non-participation would have made things worse for the person and to distinguish cases involving a mix of natural and man-made causes.

Thus, there is a compelling policy argument as well as a suggestive constitutional argument that the practice of selling parental rights in general, and in particular the practice of commercial surrogacy, should not be permitted. These arguments favor the approach adopted in New York State as opposed to any more latitudinarian approach that would permit commercial surrogacy. Clearly, if the payment of money in exchange for parental rights should be prohibited, then we have a strong basis on which to reject (...) the intentionalist theory, along with any other theory tht would link the parentage of a child with the payment of money. This conclusion is in no way undermined by the various arguments recited in part V above that favor the intentionalist theory since, as we have seen, these arguments are flawed. (shrink)

In this anthology of new and classic articles, fifteen noted feminist philosophers explore contemporary ethical issues that uniquely affect the lives of women. These issues in applied ethics include autonomy, responsibility, sexual harassment, women in the military, new technologies for reproduction, surrogate motherhood, pornography, abortion, nonfeminist women and others. Whether generated by old social standards or intensified by recent technology, these dilemmas all pose persistent, 'nagging,' questions that cry out for answers.

ISBN 0-8476-8901-8 (Paperback) This book will provide the reader with a systematic examination of some of the most (...) difficult philosophical issues involved in procreation, and most notably those raised by wrongful life claims and the non-identity problem. Can an action without which a given child would not even exist be simultaneously said to harm this very child? This is the key question addressed in this book. It is relevant not only to bioethicists, but also to those concerned with the possibility of harming members of future generations in general. The author proceeds with remarkable clarity in three steps. First, she unveils the core intuition and unfolds the key implications of what is standardly referred to as the person-affecting view. Second, she focuses on the now famous non-identity problem that is supposed to raise a serious challenge to the plausibility of the person-affecting view. Third, wrongful life and human cloning are taken as illustrations of the problem.The starting point is thus the person-affecting or personalist view. The author argues that what is at stake in such a view is not only a concern for [End Page 114] persons (as opposed to plants or stones), but also for definite persons. The core intuition that "what is bad must be bad for someone" (Derek Parfit) implies a comparison between two states of the same person. As she puts it, "the pairwise comparisons of worlds appealed to within personalism are always in respect of particular people" (6). This does not necessarily imply consequentialism, contrary to what Roberts claims (e.g., 1), at least if we understand the latter, for example, as Philip Pettit does. 1 Moreover, one may very well argue that what is at the heart of the person-affecting intuition is a sense that an action needs to be assessed on the basis of its effect on persons, which would not necessarily imply that such effects require a comparison between two states of the same person. Nevertheless, the extent to which a person-affecting conception--as defined by Roberts--will be in trouble depends on the extent to which comparisons between the same person's states cannot operate. This is precisely where to introduce the idea of a non-identity context, that is, a situation in which not committing an allegedly harmful act would or could also have meant the nonexistence of the allegedly harmed person. For example, had a medical doctor not committed this preconceptional diagnostic mistake (or a father taken a slower or faster means of transportation to come back home), this child would or could not have existed. Can we thus say that the practitioner harmed the child who turned out to be heavily handicapped due, for example, to a genetically transmissible disease (or that the father harmed his child by leaving him with a very polluted environment due to his use of big cars as a means of transportation)?One key feature of Roberts's approach is that she restricts the scope of the non-identity problem to cases where not committing the allegedly harmful action would have made it impossible for this child to have existed ("two-alternative" cases) (26, 319, 325). This entails that whenever this very child could still have come to existence in the allegedly harmful action's absence, whatever the likelihood of such a coming to existence, we would fall outside a non-identity context ("three-alternative" cases) (27; 94-95). What matters to Roberts is whether or not the same child could have been born better than he is, not whether he would, as a matter of fact, have been born at all. The consequence is that in cases where the same child could have been born, say, unhandicapped, the author remains... (shrink)

Suppose that Depletion will reduce the well-being of future people. Many of us would like to say that Depletion is wrong because of the harm to future people. However, it can easily be made to seem that Depletion is actually harmless – this is the non-identity problem.

I will argue that the magnitude of Roberts's harm is off target by many orders of magnitude: it (...) is just too tiny to explain the intuitive wrong of Depletion. (shrink)

Examining stem cell biology from a philosophy of science perspective, this book clarifies the field's central concept, the stem cell, as well as its aims, methods, models, explanations and evidential challenges. The first chapters discuss what stem cells are, how experiments identify them, and why these two issues cannot be completely separated. The basic concepts, methods and structure of the field are set out, as well as key limitations and challenges. The second part of the book shows how rigorous explanations (...) emerge from stem cell experiments, and compares these to other kinds of scientific explanation. Model organisms, the role of genes, and the significance of collaboration are also discussed. The last part of the book considers relations to systems biology and clinical medicine, arguing that both the mathematical models of the former, and ethical principles of the latter, are necessary for stem cell biology to deliver on its promises.

The Voice of Virtue illuminates the musical practices at the heart of the Neostoic movement that spread across French lands during the Wars of Religion in the latter half of the sixteenth century. Guided by twin reparative traditions granting music and philosophy therapeutic power, composers and performers across the embattled Catholic and Protestant confessions turned to moral song as a means of repairing personal and collective virtue damaged by the ongoing conflict. Moral song collections enlarged interest in Stoic philosophy by (...) circulating its ethical program to a broader audience through attractive paraphrases of Stoic maxims set to music. Even more importantly, this skillfully composed repertoire of polyphonic song offered a multi-sensory moral practice that would have resonated powerfully for those well-versed in the paradoxes of the Stoic tradition. Bringing together a repertoire of little-known music prints, a rich visual culture, and an impressive body of literary and philosophical sources, The Voice of Virtue not only illuminates the influence of Stoicism on music, but also reveals that we cannot fully understand Neostoicism as an intellectual or cultural movement without accounting for its vibrant musical sounds. Virtue, as voiced in these Stoic practices, proves to be both rational and fully invested in the sensory processes of the singing body. (shrink)

Overconfidence is typically damaging to one’s reputation as a trustworthy source of information. Previous research shows that the reputational cost associated with conveying a piece of false information is higher for confident than unconfident speakers. When judging speaker trustworthiness, individuals do not exclusively rely on past accuracy but consider the extent to which speakers expressed a degree of confidence that matched the accuracy of their claims (their “confidence-accuracy calibration”). The present study experimentally examines the interplay between confidence, accuracy and a (...) third factor, namely evidence, in the assessment of speaker trustworthiness. Experiment 1 probes the hypothesis that overconfidence does not backfire when a confident but inaccurate claim is justified: the trustworthiness of a confident speaker who turns out to be wrong is restored if the confidence expressed is based on strong evidence (good confidence-evidence calibration). Experiment 2 investigates the hypothesis that confidence can backfire if a confident and accurate claim is not justified: the trustworthiness of a confident speaker who turns out to be right is damaged if the confidence expressed is based on weak evidence (bad confidence-evidence calibration). Our results support both hypotheses and thus suggest that “confidence-evidence calibration” plays a crucial role in the assessment of speaker trustworthiness. (shrink)

We describe a first order axiom set which yields the classical first order Euclidean geometry of Tarski when used with classical logic, and yields an intuitionistic Euclidean geometry when used with intuitionistic logic. The first order language has a single six place atomic predicate and no function symbols. The intuitionistic system has a computational interpretation in recursive function theory, that is, a realizability interpretation analogous to those given by Kleene for intuitionistic arithmetic and analysis. This interpretation shows the unprovability in (...) the intuitionistic theory of certain “nonconstructive” theorems of the classical geometry. (shrink)

The present study investigated whether humans are more likely to trust people who are coordinated with them. We examined a well-known type of linguistic coordination, lexical entrainment, typically involving the elaboration of “conceptual pacts,” or partner-specific agreements on how to conceptualize objects. In two experiments, we manipulated lexical entrainment in a referential communication task and measured the effect of this manipulation on epistemic and practical trust. Our results showed that participants were more likely to trust a coordinated partner than an (...) uncoordinated one, but only when the latter broke previously established conceptual pacts. (shrink)

Anthropology of Consciousness, EarlyView.

In a critical intervention into the bioethics debate over human enhancement, philosopher Melinda Hall tackles the claim that the expansion and development of human capacities is a moral obligation. Hall draws on French philosopher Michel Foucault to reveal and challenge the ways disability is central to the conversation. The Bioethics of Enhancement includes a close reading and analysis of the last century of enhancement thinking and contemporary transhumanist thinkers, the strongest promoters of the obligation to pursue enhancement technology. With (...) specific attention to the work of bioethicists Nick Bostrom and Julian Savulescu, the book challenges the rhetoric and strategies of enhancement thinking. These include the desire to transcend the body and decide who should live in future generations through emerging technologies such as genetic selection. Hall provides new analyses rethinking both the philosophy of enhancement and disability, arguing that enhancement should be a matter of social and political interventions, not genetic and biological interventions. Hall concludes that human vulnerability and difference should be cherished rather than extinguished. -/- This book will be of interest to academics working in bioethics and disability studies, along with those working in Continental philosophy (especially on Foucault).

During the 1920s and 1930s geneticist L. C. Dunn of Columbia University cautioned Americans against endorsing eugenic policies and called attention to eugenicists' less than rigorous practices. Then, from the mid-1940s to early 1950s he attacked scientific racism and Nazi Rassenhygiene by co-authoring Heredity, Race and Society with Theodosius Dobzhansky and collaborating with members of UNESCO on their international campaign against racism. Even though shaking the foundations of scientific discrimination was Dunn's primary concern during the interwar and post-World War II (...) years, his campaigns had ancillary consequences for the discipline. He contributed to the professionalization of genetics during the 1920s and 1930s and sought respectability for human genetics in the 1940s and 1950s. My article aims to elucidate the activist scientist's role in undermining scientific discrimination by exploring aspects of Dunn's scientific work and political activism from the 1920s to 1950s.

Rufus of Ephesus's treatise Quaestiones Medicinales is unique in the known corpus of ancient medical writing. It has been taken for a procedural handbook serving an essentially operational purpose. But with its insistent message that doctors cannot properly understand and treat illnesses unless they supplement their own knowledge by questioning patients, and its distinct appreciation of the singularity of each patient's experience, Rufus's work shows itself to be no mere handbook but a treatise about the place of questioning in the (...) clinical encounter. This paper concentrates on two aspects of Rufus's thought that are unusual by comparison with other ancient medical texts: his distinctively person-centred rather than disease-based concept of questioning, and his extension of ‘habits’ beyond the dietary and occupational to include an indeterminate range of individual characteristics whose relevance to illness is not immediately obvious. In his quest for subjective information to set alongside ob.. (shrink)
