The worst possible way to resolve this issue is to leave it up to individual choice. There is no known social good coming from the conquest of death (Bailey, 1999). - Daniel Callahan Dramatically extending the human lifespan seems increasingly possible. Many bioethicists object that life-extension will have Malthusian consequences as new Methuselahs accumulate, generation by generation. I argue for a Life-Years Response to the Malthusian Objection. If even a minority of each generation chooses life-extension, denying it to them deprives (...) them of many years of extra life, and their total extra life-years are likely to exceed the total life-years of a majority who do not want life-extension. This is a greater harm to those who want extended life than the Malthusian harms to those who refuse extended life, both because losing an extra year of life is worse than enduring a year of Malthusian conditions, and because the would-be Methuselahs have more life-years at stake. Therefore, even if life-extension seems likely to cause severe overcrowding and resource shortages, that threat is not sufficient to justify society in restricting the development or availability of life-extension.

Contemporary philosophers and bioethicists argue that life extension is bad for the individual. According to the agency objection to life extension, being constrained as an agent adds to the meaningfulness of human life. Life extension removes constraints, and thus it deprives life of meaning. In the paper, I concede that constrained agency contributes to the meaningfulness of human life, but reject the agency objection to life extension in its current form. Even in an extended life, decision-making remains constrained, and many (...) obstacles to the fulfilment of an agent’s goals are preserved. Agents with longer lives are also presented with new challenges: for instance, it might be harder for them to avoid chronic boredom, and sustain their motivation to act in the pursuit of their goals. Although objections from agency and boredom are often used in combination to support the view that a much longer life is likely to bring misery or become meaningless, I argue that the acceptance of the boredom objection undermines the persuasiveness of the agency objection.

It seems to be a widespread opinion that increasing the length of existing happy lives is better than creating new happy lives although the total welfare is the same in both cases, and that it may be better even when the total welfare is lower in the outcome with extended lives. I shall discuss two interesting suggestion that seems to support this idea, or so it has been argued. Firstly, the idea there is a positive level of wellbeing above which (...) a life has to reach to have positive contributive value to a population, so-called Critical Level Utilitarianism. Secondly, the view that it makes an outcome worse if people are worse off than they otherwise could have been, a view I call Comparativism. I shall show that although these theories do capture some of our intuitions about the value of longevity, they have such counterintuitive implications in other cases that we ultimately have to reject them.

On the ethics of extending human life: healthy people have a right to carry on livingHumanity has long demonstrated a paradoxical ambivalence concerning the extension of a healthy human lifespan. Modest health extension has been universally sought, whereas extreme health extension has been regarded as a snare and delusion—a dream beyond all others at first blush, but actually something we are better off without. The prevailing pace of biotechnological progress is bringing ever closer the day when humanity will be able (...) to act on the latter view by rejecting a clear and present opportunity for much longer healthy lives. Indeed, some biogerontologists contend that that day has already arrived, to the extent that our hesitation in embarking on a vigorous “war on ageing” is already delaying the point at which a cure for ageing will be developed. Here I consider whether our present caution concerning the wisdom of truly curing ageing is likely to survive the increased scrutiny that it will receive in coming years as a result of these technical advances. I conclude that it will not, because of its irreconcilability with values that are more deeply held by the large majority of humanity than any values that argue against the quest for a cure. I further conclude that all the major current reasons given for not curing ageing are mere crutches to help us cope with the immutability of ageing that we have been brought up to accept. Our failure to set aside such irrationality is already shortening potential longevity—quite probably of those already alive today—to a staggering degree. Once we realise this, our determination to consign human ageing to history will be second …. (shrink)

The possibility of enhancing human abilities often raises public concern about equality and social impact. This chapter aims at one particular group of technologies, cognitive enhancement, and one particular fear, that enhancement will create social divisions and possibly expanding inequalities. The chapter argues that cognitive enhancements could offer significant social and economic benefits. The basic forms of internal cognitive enhancement technologies foreseen today are pharmacological modifications, genetic interventions, transcranial magnetic stimulation, and neural implants. Cognitive enhancements can influence the economy through (...) reduction of losses, individual economic benefits, and society‐wide benefits. The strongest objection to the introduction of any enhancement technology is that it will create inequality, injustice, and unfairness. While there are clear economic and social benefits to cognitive enhancement, there exist anumber of obstacles to its development and use. One obstacle is the present system for licensing drugs and medical treatments. (shrink)

There has been increasing attention in sociology and internet studies to the topic of ‘digital remains’: the artefacts users of social network services (SNS) and other online services leave behind when they die. But these artefacts also pose philosophical questions regarding what impact, if any, these artefacts have on the ontological and ethical status of the dead. One increasingly pertinent question concerns whether these artefacts should be preserved, and whether deletion counts as a harm to the deceased user and therefore (...) provides pro tanto reasons against deletion. In this paper, I build on previous work invoking a distinction between persons and selves to argue that SNS offer a particularly significant material instantiation of persons. The experiential transparency of the SNS medium allows for genuine co-presence of SNS users, and also assists in allowing persons (but not selves) to persist as ethical patients in our lifeworld after biological death. Using Blustein’s “rescue from insignificance” argument for duties of remembrance, I argue that this persistence function supplies a nontrivial (if defeasible) obligation not to delete these artefacts. Drawing on Luciano Floridi’s account of “constitutive” information, I further argue that the “digital remains” metaphor is surprisingly apt: these artefacts in fact enjoy a claim to moral regard akin to that of corpses.

Biomedical technologies can increasingly be used not only to combat disease, but also to augment the capacities or traits of normal, healthy people – a practice commonly referred to as biomedical enhancement. Perhaps the best‐established examples of biomedical enhancement are cosmetic surgery and doping in sports. But most recent scientific attention and ethical debate focuses on extending lifespan, lifting mood, and augmenting cognitive capacities.

I argue against two popular claims. The first is a descriptive, empirical thesis about the nature of ordinary human experience: ‘each of us constructs and lives a “narrative” . . . this narrative is us, our identities’ (Oliver Sacks); ‘self is a perpetually rewritten story . . . in the end, we become the autobiographical narratives by which we “tell about” our lives’ (Jerry Bruner); ‘we are all virtuoso novelists. . . . We try to make all of our material (...) cohere into a single good story. And that story is our autobiography. The chief fictional char- acter . . . of that autobiography is one’s self’ (Dan Dennett). The second is a normative, ethical claim: we ought to live our lives narratively, or as a story; a ‘basic condition of making sense of ourselves is that we grasp our lives in a narrative’ and have an understanding of our lives ‘as an unfolding story’ (Charles Taylor). A person ‘creates his identity [only] by forming an autobiographical narrative – a story of his life’, and must be in possession of a full and ‘explicit narrative [of his life] to develop fully as a person’ (Marya Schechtman).

Can we understand what makes someone the same person without understanding what it is to be a person? Prereflectively we might not think so, but philosophers often accord these questions separate treatments, with personal-identity theorists claiming the first question and free-will theorists the second. Yet much of what is of interest to a person—the possibility of survival over time, compensation for past hardships, concern for future projects, or moral responsibility—is not obviously intelligible from the perspective of either question alone. Marya (...) Schechtman encourages us to adopt a more unified perspective. (shrink)

Abstract Of the many ways in which identity is constructed and performed online, few are as strongly ‘anchored’ to existing offline relationships as in online social networks like Facebook and Myspace. These networks utilise profiles that extend our practical, psychological and even corporeal identity in ways that give them considerable phenomenal presence in the lives of spatially distant people. This raises interesting questions about the persistence of identity when these online profiles survive the deaths of the users behind them, via (...) the practice of ‘memorialising’ social network profile pages. I situate these practices within a phenomenology of grief that accounts for the ways in which the dead can persist as moral patients, and show how online survival in this case illuminates an important difference between persons and selves within contemporary philosophy of personal identity. Ultimately, the online persistence of the dead helps bring into view a deep ontological contradiction implicit in our dealings with death: the dead both live on as objects of duty and yet completely cease to exist.

Many philosophers have taken there to be an important relation between personal identity and several of our practical concerns (among them moral responsibility, compensation, and self-concern). I articulate four natural methodological assumptions made by those wanting to construct a theory of the relation between identity and practical concerns, and I point out powerful objections to each assumption, objections constituting serious methodological obstacles to the overall project. I then attempt to offer replies to each general objection in a way that leaves (...) the project intact, albeit significantly changed. Perhaps the most important change stems from the recognition that the practical concerns motivating investigation into personal identity turn out to be not univocal, as is typically thought, such that each of the different practical concerns may actually be related to personal identity in very different ways.

A popular “Reductionist” account of personal identity unifies person stages into persons in virtue of their psychological continuity with one another. One objection to psychological continuity accounts is that there is more to our personal identity than just mere psychological continuity: there is also an active process of self-interpretation and self-creation. This criticism can be used to motivate a rival account of personal identity that appeals to the notion of a narrative. To the extent that they comment upon the issue, (...) proponents of narrative accounts typically reject Reductionist metaphysics that (ontologically) reduce persons to aggregates of person stages. In contrast to this trend, we seek to develop a narrative account of personal identity from within Reductionist metaphysics: we think person stages are unified into persons in virtue of their narrative continuity with one another. We argue that this Reductionist version of the narrative account avoids some serious problems facing non-Reductionist versions of the narrative account. (shrink)

There has been considerable recent debate on the ethics of human enhancement. A number of prominent authors have been concerned about or critical of the use of technology to alter or enhance human beings, citing threats to human nature and dignity as one basis for these concerns. Frances Kamm has given a detailed rebuttal of Sandel's arguments, arguing that human enhancement is permissible. Nicholas Agar, in his book Liberal Eugenics, argues that enhancement should be permissible but not obligatory. He argues (...) that what distinguishes liberal eugenics from the objectionable eugenic practices of the Nazis is that it is not based on a single conception of a desirable genome and that it is voluntary and not obligatory. This article takes a more provocative position. It aims to argue that, far from its being merely permissible, we have a moral obligation or moral reason to enhance ourselves and our children. Indeed, we have the same kind of obligation as we have to treat and prevent disease. It begins by considering the current interests in and possibilities of enhancement. It then offers three arguments that we have very strong reasons to seek to enhance. (shrink)

Some bioethicists have questioned the desirability of a line of biomedical research aimed at extending the length of our lives over what some think to be its natural limit. In particular, Leon Kass has argued that living longer is not such a great advantage, and that mortality is not a burden after all. In this essay, I evaluate his arguments in favour of such a counterintuitive view by elaborating upon some critical remarks advanced by John Harris. Ultimately, I argue that (...) nothing substantial has been said by Kass to undermine the desirability of life-extending technologies. (shrink)

In a recent article in this journal, John Lippitt mounts a forceful argument against narrativist approaches to issues in personal identity and practical deliberation, with specific reference to the application of such approaches in the interpretation of Kierkegaard's writings. The present critical discussion piece addresses two points in Lippitt's argument. First, it seeks to meet Lippitt's challenge to clarify the notion of "a whole life" as this figures in narrativist positions. Second, it clarifies the sense in which narrative unity, and (...) even selfhood, may be a matter of degree. It then uses this latter insight to sketch a defense of the claim that narrativity may indeed play a crucial role in Kierkegaard's distinction between ethical and aesthetic ways of life. (shrink)

Over the last few decades, a number of influential philosophers, psychologists and others have invoked the notion of narrative as having a central role to play in our thinking about ethics and personal identity. More recently, a backlash against these narrative theories has developed, exemplified in work by, for instance, Galen Strawson, Peter Lamarque and John Christman. This paper defends an approach to personal identity and ethics, influenced mainly by Alasdair MacIntyre and Charles Taylor, in which narrative plays a central (...) (though not a foundational) role. In sec I, I elucidate the concept of narrative that MacIntyre introduced in After Virtue and show why this is central to thinking about the identity of persons across time. In sec II, I consider and reject various objections to this narrative account of personal identity. I hope to show that some of the prominent criticisms of narrative theory simply don’t apply to this conception, properly understood. However, I don’t want to claim that the dispute over narrative is based purely on misunderstanding, One centrally important aspect of the dispute is a first-order ethical one about the extent to which we should seek for a unity based on narrative coherence in our lives, and in secs III and IV, I will offer a defence of Taylor’s claim that an ethical life must aspire to, and to some extent achieve, narrative unity.

Debates about the ethical and social implications of research that aims to extend human longevity by intervening in the ageing process have paid little attention to the attitudes of members of the general public. In the absence of empirical evidence, conflicting assumptions have been made about likely public attitudes towards life-extension. In light of recent calls for greater public involvement in such discussions, this target article presents findings from focus groups and individual interviews which investigated whether members of the general (...) public identify ethical issues surrounding life-extension, and if so, what these ethical issues are? In this study, while some participants were concerned primarily with the likely personal consequences of life-extension, for others the question of whether or not to pursue interventions to extend longevity, and how they should be implemented, clearly raised important ethical issues, many of which have been prominent in debates among bioethicists.

This paper is about the neglected question of what sort of things we are metaphysically speaking. It is different from the mind-body problem and from familiar questions of personal identity. After explaining what the question means and how it differs from others, the paper tries to show how difficult it is to give a satisfying answer.

If personhood involves the construction of a narrative identity, then what are we to say of someone who is seriously ill or disabled? How can her life have any narrative when she is unable to write one?

The ever-expanding literature on narrative reveals a striking divergence of claims about the epistemic valence of narrative. One such claim is the oftstated idea that narratives or stories generate both “hot” and “cold” epistemic irrationality. A familiar, rival claim is that narrative has an exclusive capacity to embody or convey important types of knowledge. Such contrasting contentions are not typically presented as statements about the accidents or effects of particular narratives; the ambition, rather, has been to identify a strong link (...) between a single, positive or negative epistemic valence and narrativity, or the traits in virtue of which some discourse, utterance, or series of thoughts is aptly classified as a narrative or story. In this essay I contend that arguments in this vein are dubious.Not only are contentions about the specificity of narrative tenuous and controversial, but even if they were not, there are serious problems with the postulated connections between narrativity and the epistemic merits or demerits of narratives. These difficulties are identified in a critical discussion of prominent examples from the literature. My conclusion is not that there is nothing worth saying about relations between narratives and various epistemic desiderata, but that one prevalent theoretical ambition in this area ought to be renounced in favor of more viable avenues of inquiry.

As part of the widespread turn to narrative in contemporary philosophy, several commentators have recently attempted to sign Kierkegaard up for the narrative cause, most notably in John Davenport and Anthony Rudd's recent collection Kierkegaard After MacIntyre: Essays on Freedom, Narrative and Virtue. I argue that the aesthetic and ethical existence‐spheres in Either/Or cannot adequately be distinguished in terms of the MacIntyre‐inspired notion of ‘narrative unity’. Judge William's argument for the ethical life contains far more in the way of substantive (...) normative content than can be encapsulated by the idea of ‘narrative unity’, and the related idea that narratives confer intelligibility will not enable us to distinguish Kierkegaardian aesthetes from Kierkegaardian ethicists. ‘MacIntyrean Kierkegaardians’ also take insufficient notice of further problems with MacIntyre's talk of ‘narrative unity’, such as his failure to distinguish between literary narratives and the ‘enacted dramatic narratives’ of which he claims our lives consist; the lack of clarity in the idea of a ‘whole life’; and the threat of self‐deception. Finally, against the connections that have been drawn between Kierkegaardian choice and Harry Frankfurt's work on volitional identification, I show something of the dangers involved in putting too much stress on unity and wholeheartedness.

Scientists, bioethicists, and policy makers are currently engaged in a contentious debate about the scientific prospects and morality of efforts to increase human longevity. Some demographers and geneticists suggest that there is little reason to think that it will be possible to significantly extend the human lifespan. Other biodemographers and geneticists argue that there might well be increases in both life expectancy and lifespan. Bioethicists and policy makers are currently addressing many of the ethical, social, and economic issues raised by (...) life extension research. However, the emphasis on philosophical argument supporting or condemning efforts to increase human longevity means that much less attention is currently being given to the factors that might play a role in generating interest in efforts to increase human longevity. This analysis considers three factors that might play a role in heightening public interest in efforts to develop biomedical technologies capable of retarding or reversing aging processes. While discussions of life extension research can seem quite futuristic and impractical, there are some powerful existential factors that might well generate considerable public support for life extension strategies if effective biomedical interventions emerge. Rather than providing philosophical justifications supporting or condemning efforts to increase human longevity, this essay seeks to promote a better understanding of the factors generating contemporary interest in prolonging life and postponing death.

The paper offers a mildly deflationary account of narrative, drawing attention to the minimal, thus easily satisfied, conditions of narrativity and showing that many of the more striking claims about narrative are either poorly supported or refer to distinct classes of narrative—usually literary or fictional—which provide a misleading paradigm for narration in general. An enquiry into structural, referential, pragmatic, and valuebased features of narrative helps circumscribe the limits of narration and the test case of the narrative definition of the self (...) is examined and shown to yield rather less that is often claimed.

ABSTRACT The emerging discourse concerning the desirability of intervention in senescence to achieve radical life extension for persons has featured some striking blurring in traditional liberal and conservative commitments and positions. This affords an opportunity for re‐evaluation of these same. The canonical conservative view of the intrinsic value of life is re‐examined and found primarily to involve a denial of human prerogative, rather than an active underwriting of the value of life extension. A critique is offered of an attempted argument (...) against aging intervention from a proto‐conservative worry about a purported threat to human nature. Immortality is found to be a red herring, but a revealing one. Further, the classic liberal view is examined and found wanting in terms of the gravity of its own commitment to, and fullness of its account of the value of life, and the value of life extension. An analysis of the liberal conception of personhood is proposed that both defines persons necessarily as processes, and demonstrates the inalienable quality of the value of life extension to persons so defined.

Recent advances in human genetics suggest that it may become possible to genetically manipulate telomerase and embryonic stem cells to alter the mechanisms of aging and extend the human life span. But a life span significantly longer than the present norm would be undesirable because it would severely weaken the connections between past‐ and future‐oriented mental states and in turn the psychological grounds for personal identity and prudential concern for our future selves. In addition, the collective effects of longer lives (...) might lower the quality of life for all people. These two problems provide reasons against genetic manipulation of cells to alter the length of the human life span. (shrink)

From the time of Locke, discussions of personal identity have often ignored the question of our basic metaphysical nature: whether we human people are biological organisms, spatial or temporal parts of organisms, bundles of perceptions, or what have you. The result of this neglect has been centuries of wild proposals and clashing intuitions. What Are We? is the first general study of this important question. It beings by explaining what the question means and how it differs from others, such as (...) questions of personal identity and the mind-body problem. It then examines in some depth the main possible accounts of our metaphysical nature, detailing both their theoretical virtues and the often grave difficulties they face. The book does not endorse any particular account of what we are, but argues that the matter turns on more general issues in the ontology of material things. If composition is universal–if any material things whatever make up something bigger–then we are temporal parts of organisms. If things never compose anything bigger, so that there are only mereological simples, then we too are simples–perhaps the immaterial substances of Descartes–or else we do not exist at all . The intermediate view that some things compose bigger things and others do not leads almost inevitably to the conclusion that we are organisms. So we can discover what we are by working out when composition occurs. (shrink)

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I.J. Good in his 1965 article “Speculations Concerning the First Ultraintelligent Machine”: Let an ultraintelligent machine be defined as a machine that can far (...) surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an “intelligence explosion”, and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make. The key idea is that a machine that is more intelligent than humans will be better than humans at designing machines. So it will be capable of designing a machine more intelligent than the most intelligent machine that humans can design. So if it is itself designed by humans, it will be capable of designing a machine more intelligent than itself. By similar reasoning, this next machine will also be capable of designing a machine more intelligent than itself. If every machine in turn does what it is capable of, we should expect a sequence of ever more intelligent machines. This intelligence explosion is sometimes combined with another idea, which we might call the “speed explosion”. The argument for a speed explosion starts from the familiar observation that computer processing speed doubles at regular intervals. Suppose that speed doubles every two years and will do so indefinitely. Now suppose that we have human-level artificial intelligence 1 designing new processors. Then faster processing will lead to faster designers and an ever-faster design cycle, leading to a limit point soon afterwards. The argument for a speed explosion was set out by the artificial intelligence researcher Ray Solomonoff in his 1985 article “The Time Scale of Artificial Intelligence”.1 Eliezer Yudkowsky gives a succinct version of the argument in his 1996 article “Staring at the Singularity”: “Computing speed doubles every two subjective years of work..

Is the self narratively constructed? There are many who would answer yes to the question. Dennett (1991) is, perhaps, the most famous proponent of the view that the self is narratively constructed, but there are others, such as Velleman (2006), who have followed his lead and developed the view much further. Indeed, the importance of narrative to understanding the mind and the self is currently being lavished with attention across the cognitive sciences (Dautenhahn, 2001; Hutto, 2007; Nelson, 2003). Emerging from (...) this work, there appear to be a variety of ways in which we can think of the narrative construction of the self and the relationship between the narrative self and the embodied agent. I wish to examine two such ways in this paper. The first I shall call the abstract narrative account, this is because its proponents take the narrative self to be an abstraction (Dennett, 1991; Velleman, 2006). Dennett, for example, refers to the self as a centre of narrative gravity, to be thought of as analogous to a mathematical conception of the centre of gravity of an object. The second I shall call the embodied narrative account and this is the view that the self is constituted both by an embodied consciousness whose experiences are available for narration and narratives themselves, which can play a variety of roles in the agent’s psychological life.

Wielding his philosophical razor, William of Ockham declared, in the early 14th century, that in slicing the world into categories, thou shalt not multiply entities needlessly. He might have been pleased when, half a millennium later, James Clerk Maxwell helped tidy things up by writing the equations that show magnetism and electricity as perpendicular shadows cast by light beams, radio waves, X-rays and other forms of what we now call electromagnetic radiation. Einstein did Maxwell one better by equating mass with (...) energy. And today the physicists promise us that once we give them their superconducting supercollider, they will take a giant step toward the day when they can unify light with gravity and the two forces at work inside the nuclei of atoms -- showing how everything, even the geometry of space and time, crystallized from the primordial flash of the big bang.
