A key to modern studies of 18th century Western philosophy, the Treatise considers numerous classic philosophical issues, including causation, existence, freedom and necessity and morality. This abridged edition has an introduction which explain's Hume's thought and places it in the context of its times.

With the help of medicine and technology we are living longer than ever before. As human life spans have increased, the moral and political issues surrounding longevity have become more complex. Should we desire to live as long as possible? What are the social ramifications of longer lives? How does a longer life span change the way we think about the value of our lives and about death and dying? Christine Overall offers a clear and intelligent discussion of the philosophical (...) and cultural issues surrounding this difficult and often emotionally charged issue. Her book is unique in its comprehensive presentation and evaluation of the arguments—both ancient and contemporary—for and against prolonging life. It also proposes a progressive social policy for responding to dramatic increases in life expectancy. Writing from a feminist perspective, Overall highlights the ways that our biases about race, class, and gender have affected our views of elderly people and longevity, and her policy recommendations represent an effort to overcome these biases. She also covers the arguments surrounding the question of the "duty to die" and includes a provocative discussion of immortality. After judiciously weighing the benefits and the risks of prolonging human life, Overall persuasively concludes that the length of life does matter and that its duration can make a difference to the quality and value of our lives. Her book will be an essential guide as we consider our social responsibilities, the meaning of human life, and the prospects of living longer. (shrink)

Aristotle's Nicomachean Ethics, based on lectures that he gave in Athens in the fourth century BCE, is one of the most significant works in moral philosophy, and has profoundly influenced the whole course of subsequent philosophical endeavour. It is soundly located within a philosophical tradition, but its argument differs markedly from those of Plato and Socrates in its emphasis on the exercise - as opposed to the mere possession - of virtue as the key to human happiness, offering seminal discussions (...) of ethical issues that are practical in their intent. Topics covered include the role of luck in human wellbeing, moral education, responsibility, courage, justice, moral weakness, friendship and pleasure. This accessible new translation by Roger Crisp follows the Greek text closely and also provides a non-Greek-reader with the flavour of the original. The volume also includes a historical and philosophical introduction and notes on further reading. (shrink)

Allocation of very scarce medical interventions such as organs and vaccines is a persistent ethical challenge. We evaluate eight simple allocation principles that can be classified into four categories: treating people equally, favouring the worst-off, maximising total benefits, and promoting and rewarding social usefulness. No single principle is sufficient to incorporate all morally relevant considerations and therefore individual principles must be combined into multiprinciple allocation systems. We evaluate three systems: the United Network for Organ Sharing points systems, quality-adjusted life-years, and (...) disability-adjusted life-years. We recommend an alternative system—the complete lives system—which prioritises younger people who have not yet lived a complete life, and also incorporates prognosis, save the most lives, lottery, and instrumental value principles.

Some people claim that death makes our lives meaningless. Bernard Williams and Viktor Frankl have made the opposite claim that death gives meaning to life. Although there has been much scrutiny of the former claim, the latter claim has received very little attention. In this paper, I will explore whether and how death gives meaning to our lives. As I will argue, there is not sufficient support for the strong claim that death is necessary for one's life to be meaningful. (...) However, there is support for the more limited conclusion that our finitude enhances or upholds the meaning in the lives of some individuals in four different ways. (shrink)

This chapter critically explores contemporary philosophical understandings of whether meaning in life might depend on the presence or absence of an afterlife. After distinguishing various kinds of afterlife, it focuses most on the potential relevance of an eternal one, and considers at length the extreme but common views amongst philosophers that an eternal afterlife would be either necessary for a meaningful life or, conversely, sufficient for a meaningless one. It concludes by considering the plausibility of a more moderate view, that (...) an eternal afterlife could substantially enhance the meaning of our lives, even if they would not be meaningless without it. The aim of the chapter is not to defend some overall thesis about these positions, but rather to acquaint the reader with recent English-speaking philosophical discussions of them. (shrink)

What's wrong with designer children, bionic athletes, and genetic engineering.

Once upon a time, the planet was tyrannized by a giant dragon. The dragon stood taller than the largest cathedral, and it was covered with thick black scales. Its red eyes glowed with hate, and from its terrible jaws flowed an incessant stream of evil-smelling yellowishgreen slime. It demanded from humankind a blood-curdling tribute: to satisfy its enormous appetite, ten thousand men and women had to be delivered every evening at the onset of dark to the foot of the mountain (...) where the dragontyrant lived. Sometimes the dragon would devour these unfortunate souls upon arrival; sometimes again it would lock them up in the mountain where they would wither away for months or years before eventually being consumed.

Epicurus argued that death can be neither good nor bad because it involves neither pleasure nor pain. This paper focuses on the deprivation account as a response to this Hedonist Argument. Proponents of the deprivation account hold that Epicurus’s argument fails even if death involves no painful or pleasurable experiences and even if the hedonist ethical system, which holds that pleasure and pain are all that matter ethically, is accepted. I discuss four objections that have been raised against the deprivation (...) account and argue that this response to Epicurus’s argument is successful once it has been sufficiently clarified.

(1994). Why immortality is not so bad. International Journal of Philosophical Studies: Vol. 2, No. 2, pp. 257-270.

Many religious thinkers hold the immortality requirement, the view that immortality of some kind is necessary for life to have meaning. After clarifying the nature of the immortality requirement, this essay examines three central arguments for it. The article establishes that existing versions of these arguments fail to entail the immortality requirement. The essay then reconstructs the arguments, and it shows that once they do plausibly support the immortality requirement, they equally support the God-centred requirement, the view that God's existence (...) is a necessary condition for life to be meaningful. The paper concludes by explaining why we should expect any argument for the immortality requirement also to constitute an argument for the God-centred requirement. (shrink)

A critical overview of mainly Anglo-American philosophical literature addressing the meaning of life up to 2002.

A volume of philosophical studies, centred on problems of personal identity and extending to related topics in the philosophy of mind and moral philosophy.

This paper argues that we can see our lives as a snapshot happening now or as a moving picture extending across time. These dual ways of seeing our lives inform how we conceive of the problem of age group justice. A snapshot view sees age group justice as an interpersonal problem between distinct age groups. A moving picture view sees age group justice as a first-person problem of prudential choice. This paper explores these different ways of thinking about age group (...) justice and illustrates them using a principle of respect for human dignity, understood in terms of reasonable support for floor level central human capabilities at each stage of life. I argue that different frames are suitable for different kinds of decisions, and each provides a true, but partial, picture of aging and age group justice. (shrink)

Applied ethics is home to numerous productive subfields such as procreative ethics, intergenerational ethics and environmental ethics. By contrast, there is far less ethical work on ageing, and there is no boundary work that attempts to set the scope for ‘ageing ethics’ or the ‘ethics of ageing’. Yet ageing is a fundamental aspect of life; arguably even more fundamental and ubiquitous than procreation. To remedy this situation, I examine conceptions of what the ethics of ageing might mean and argue that (...) these conceptions fail to capture the requirements of the desired subfield. The key reasons for this are, first, that they view ageing as something that happens only when one is old, thereby ignoring the fact that ageing is a process to which we are all subject, and second that the ageing person is treated as an object in ethical discourse rather than as its subject. In response to these shortcomings I put forward a better conception, one which places the ageing person at the centre of ethical analysis, has relevance not just for the elderly and provides a rich yet workable scope. While clarifying and justifying the conceptual boundaries of the subfield, the proposed scope pleasingly broadens the ethics of ageing beyond common negative associations with ageing. (shrink)

In this paper I explore in a preliminary way the interconnections among narrative explanation, narrative value, free will, an immortality. I build on the fascinating an suggestive work of David Velleman. I offer the hypothesis that our acting freely is what gives our lives a distinctive kind of value - narrative value. Free Will, then, is connected to the capacity to lead a meaningful life in a quite specific way: it is the ingredient which, when aded to others, enows us (...) with a meaning over an above the cumulative value erived from ading together levels of momentary welfare. In acting freely, we are writing a sentence in the story of our lives, and the value of acting freely is thus a species of the value of artistic creativity or self-expression (understood appropriately). Finally, I contend that the fact that our lives are stories need not entail that they have endings, or that immortality would necessarily be unimaginable or essentially different from ordinary, finite human life. Yes, a certain sort of narrative understanding of our lives as a whole would be impossible in the context of immortality; but much of what we care about, and value, in our stories might remain.

In this paper I discuss some of Martha Nussbaum's defenses of Epicurean views about death and immortality. Here I seek to defend the commonsense view that death can be a bad thing for an individual against the Epicurean; I also defend the claim that immortality might conceivably be a good thing. In the development of my analysis, I make certain connections between the literatures on free will and death. The intersection of these two literatures can be illuminated by reference to (...) my notion of a Dialectical Stalemate. (shrink)

Societal aging raises challenging ethical questions regarding the just distribution of health care between young and old. This article considers a proposal for age-based rationing of health care, which is based on the prudential life span account of justice between age groups. While important objections have been raised against the prudential life span account, it continues to dominate scholarly debates. This article introduces a new objection, one that develops out of the well-established disability critique of social contract theories. I show (...) the implications of this critique for the prudential life span account and for the special case of age-group justice. The result is that age-based rationing based on the prudential life span approach is not supported, and that the prudential life span approach itself is not the best way to think about allocating health care between age groups. I propose an alternative approach that avoids the disability objection, and consider its implications for specific proposals for age-based rationing of health care. (shrink)

In the paper, after clarifying terms such as ‘identity’, ‘self’ and ‘personhood’, I propose an empirical account of identity based on the notion of “whole phenotype”. This move allows one to claim the persistence of the individuals before and after their being affected by dementia. Furthermore, I show how this account permits us to address significant questions related to demented individuals’ loss of the capacity of moral decisions.

Abstract Objections to life extension often focus on its effects for individual well-being. Prominent amongst these concerns is the possibility that life extending technologies will extend lifespan without preventing the ageing of the mind. Writers on the subject express the fear that life extending drugs will keep us physically youthful whilst our minds decay, succumbing to dementia, boredom, and loneliness. Generally these fears remain speculative, in part due to the absence of genuine life extending technologies. In this paper, however, I (...) examine the implications of an existing life extension technology. Caloric restriction (CR) and drugs that mimic its effects, such as rapamycin, metformin and resveratrol have been shown to increase average and maximum lifespan in a wide variety of organisms, and seem likely to do so in humans. Moreover, some CR mimetic drugs (CRMs) are already widely used. This means that they present a pressing test case for fears about mental ageing in an extended life. Misgivings about mental ageing can be divided into biomedical factors such as the likelihood of brain ageing, and psychological factors such as loss of meaning and boredom. I argue that studies of CR suggest that brain ageing will be beneficially slowed. However, it is less clear that deleterious aspects of psychological ageing can be similarly retarded. I argue that this reduces the desirability of life extension unless major social changes can be made. (shrink)

As average lifespans stretch to new lengths, how are human values impacted? Should our values change over the course of our ever-increasing lifespans? Nancy S. Jecker introduces a new concept, the life stage relativity of values, which holds that at different life stages, different ethical concerns should take center stage. For Jecker, the privileging of midlife values raises fundamental problems of fairness, and reveals large gaps in ethical principles and theories. Jecker introduces a new philosophical framework that reflects the life (...) stage relativity of values and shows its relevance to practice and policy. (shrink)

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)

During his celebrated 1922 debate with Bergson, Einstein famously proclaimed: “the time of the philosopher does not exist, there remains only a psychological time that differs from the physicist’s.” Einstein’s dictum, I maintain, has been metabolized by the natural sciences, which typically presuppose, more or less explicitly, the existence of a single, univocal, temporal substratum, ultimately determined by physics. This reductionistic assumption pervades much biological and biomedical practice. The chronological age allotted to individuals is conceived as an objective quantity, allowing (...) one to straightforwardly assign and compare the biological age of organisms. This essay argues that the standard practice of assessing the age and aging of organisms against the backdrop of a physical conception of time is problematic. This becomes especially evident in light of recent discoveries of various levels of senescence underlying the development of individual organisms—a phenomenon known as ‘age mosaicism.’ The bottom line is that the study of age and aging requires a biological conception of time, as opposed to a physical one. Einstein clearly wasn’t wrong about his operationalization of time in relativity theory. Still time may be less monolithic than he surmised. (shrink)

Prevention of age-related disorders is increasingly in focus of health policies, and it is hoped that early intervention on processes of deterioration can promote healthier and longer lives. New opportunities to slow down the aging process are emerging with new fields such as personalized nutrition. Data-intensive research has the potential to improve the precision of existing risk factors, e.g., to replace coarse-grained markers such as blood cholesterol with more detailed multivariate biomarkers. In this paper, we follow an attempt to develop (...) a new aging biomarker. The vision among the project consortium, comprising both research and industrial partners, is that the new biomarker will be predictive of a range of age-related conditions, which may be preventable through personalized nutrition. We combine philosophical analysis and ethnographic fieldwork to explore the possibilities and challenges of managing aging through bodily signs that are not straightforwardly linked to symptomatic disease. We document how the improvement of measurement brings about new conceptual challenges of demarcating healthy and unhealthy states. Moreover, we highlight that the reframing of aging as risk has social and ethical implications, as it is generative of normative notions of what constitutes successful aging and good citizenship.

The development of gene-editing technologies, such as the clustered regularly interspaced short palindromic repeats and associated Cas9 endonuclease system, coincides with a rapidly expanding knowledge of the role of genes in the human ageing process. This raises the prospect that, in addition to the treatment of genetic diseases and disorders, it may become possible to use gene-editing technologies to alter the ageing process and significantly extend the maximum human lifespan. Germline editing poses distinctive problems due to its implications for individual (...) members of future, unborn generations. In this essay, I wish to home in, narrowly, on a single ethical objection to extending the lifespan of future generations by editing the human germline. The objection suggests that to extend lifespans is to unethically inflict the harm of loneliness on future people. I claim that the argument rests on assumptions that ought to be rejected. (shrink)

Is it virtuous for someone to try to live to 100? Casting aside questions of intergenerational justice and internal obligations in families, what about the basic desire itself? Discussions of longevity and aging in bioethics are skewed to controversial end‐of‐life decisions, largely avoiding questions of how to age well before such decisions arise. Respected writers such as Atul Gawande, Daniel Callahan, and Ezekiel Emanuel champion accepting a natural life span and not trying to live beyond it. The Stoic Seneca says (...) a desire to live to 100 is foolish because, however long people live, they waste most of their lives, so if they lived a thousand years, they would still waste most of it. Against Seneca and Emanuel, we argue that a functional, not a chronological, view of aging should guide us and that for some seniors, hoping to be centenarians may be neither foolish nor misguided. Using Cicero, we argue that the pleasures of seniors are not necessarily inferior to those of youth and may even surpass them. Finally, we agree with Emanuel that the “symptom burden” of some lives makes living to 100 unpalatable and with Seneca that, given life’s vicissitudes, we should not plan on living to 100, but heeding his wisdom, try to make the most of the time given to us.
