Universal basic income proposes providing instalments of constant magnitude to all. One problem with a stable basic income across life is that it seems unfair to shorter-lived persons, who are worst-off due to premature death and receive less over their whole lives. Basic capital solves this problem by providing a one-off grant to the young, but I argue that it mistreats long-lived persons, as it does not guarantee their real freedom across life. There is a dilemma between these proposals regarding (...) their respective unfairness to the short- and long-lived. The solution I propose is a net basic income of decreasing magnitude until a specific age, after which the income is constant. This solution is compatible with constant income benefits across life, and it offers a fair answer to the problem of unequal longevity, a widely neglected but essential challenge in debates about basic income.

Despite being increasingly available to us all, retirement pensions remain unequally distributed: between rich and poor, young and old, men and women, and possibly different generations. As this topic receives little attention in moral and political philosophy, the articles in this thesis aim to deliver an original account of justice in retirement pensions along liberal egalitarian lines. The first part defends retirement pensions as a distribution of free time. It shows that including free time in the list of goods that (...) liberal egalitarians prioritise is plausible and avoids problems that would otherwise arise with other candidates, most notably leisure. Retirement as free time is an essential feature of liberal egalitarian societies by (re)distributing the means to pursue any life project, and especially valuable for the poor who work and contribute the longest. The second part makes a case for 'libertirement', a proposal to increase the freedom to enjoy free time across life, as a matter of justice between those who live long and those who die early. Specifically, I propose adding reverse pensions and sabbaticals on top of old-age retirement. Besides showing the importance of longevity for age-group justice, I also draw implications for distributing unconditional basic income and income taxes across life, which I suggest may offer alternative paths to libertirement. Finally, the third part discusses the cases of pension inequality between genders and generations, pushing us to refine our account further. I conclude that there is often a mismatch between liberal egalitarian justice and the design of retirement schemes. The solution is often but not always to reform these systems. Sometimes, we have reasons to revise our very own principles of justice. (shrink)

Justice Across Ages offers an attractive account of justice between the young and the old that brings together three notable principles of age-group justice: complete-lives equality, relational equality, and prudence. Yet, the book says little about the fact that many of us live longer than others, and the little it does say casts doubt on whether lifespan inequality threatens justice as construed by the three principles. This essay argues, instead, that theories of justice between the young and the old should (...) not dispense with a conception of justice between different longevity groups. It concludes that we must be sensitive to lifespan variations when designing policies to promote justice across age groups. (shrink)

In current dairy farming it is possible to run a profitable farm without having to adapt the system to the needs of dairy cows. In such systems the interests of the farmer and animals often diverge. Consequently, specific animal welfare problems occur. Foot disorders in dairy cattle are an illustrative example resulting from the specific methods of housing and management in current dairy farming. Foot disorders and the resulting lameness are considered the most important welfare problem in dairy farming. However, (...) these foot disorders not only typify welfare problems related to certain housing systems, but they also lead to the premature culling of cows. The assessment of the impact of foot disorders on the welfare of dairy cows raised the question of whether premature culling affects animal welfare since it affects the longevity of a cow. We argue that this aspect of longevity is morally relevant as an animal welfare issue. In this paper we aim to explore whether longevity is both (a) a morally relevant aspect in the discussion on killing animals and (b) a constitutive element of animal welfare. In other words, we aim to explore whether longevity is an independent moral argument in an animal welfare discussion. We claim that longevity is not merely important as an indicator of animal welfare, but is also a constitutive element of animal welfare. We argue that we need a more integrated approach to animal welfare and that an assessment that includes the aspect of time is necessary. This view involves a shift from views on animal welfare in terms of functioning or feeling well to a view on animal welfare that includes the aspect of natural living in which species-specific development is important. To show the impact of these points of view, we look at the practical implications for choices concerning the management of foot disorders in dairy cattle. (shrink)

An explosion in the varieties of life-extending interventions for older persons is changing the face of many medical specialties in the United States, altering the nature of end-stage disease, and reshaping societal expectations about normal old age, longevity, and the time for death. There is no doubt that the rapid growth of the over-85 age group and better health in late life for many people in the United States are redefining “old.” Robert Butler, founding director of the National Institute (...) on Aging, has stated that “80 is the new 60,” adding to other popular remarks that signify a changed understanding of life course expectations, especially for those who can access all that medicine has to offer.

A UN report, which comprehensively documents the advance of global population ageing, was released on 1 October 2012, the International Day of Older Persons. In the West, this development has been accelerated by and will be profoundly experienced by the baby boomers. As they reach ages historically linked with retirement their numbers are rising, as are expectations for annual age-related public spending. Vulnerabilities are regularly being exposed in terms of medical care, social care and inadequate retirement planning. This makes acceptance (...) of the traditional narrative for ageing, including passivity, complacency and accelerating dependency, patently unsustainable. Medical and technological advancements have given this cohort an achievement award in terms of longer, healthier lives and there is a choice to make. Either substantive changes to redefine this life stage are made or the salutary lesson afforded by the new longevity could be squandered. (shrink)

Gott ( 1993 ) has used the ‘Copernican principle’ to derive a probability distribution for the total longevity of any phenomenon, based solely on the phenomenon’s past longevity. Leslie ( 1996 ) and others have used an apparently similar probabilistic argument, the ‘Doomsday Argument’, to claim that conventional predictions of longevity must be adjusted, based on Bayes’s Theorem, in favor of shorter longevities. Here I show that Gott’s arguments are flawed and contradictory, but that one of his (...) conclusions is plausible and mathematically equivalent to Laplace’s famous—and notorious—‘rule of succession’. On the other hand, the Doomsday Argument, though it appears consistent with some common‐sense grains of truth, is fallacious; the argument’s key error is to conflate future longevity and total longevity. Applying the work of Hill ( 1968 ) and Coolen ( 1998 , 2006 ) in the field of nonparametric predictive inference, I propose an alternative argument for quantifying how past longevity of a phenomenon does provide evidence for future longevity. In so doing, I identify an objective standard by which to choose among counting time intervals, counting population, or counting any other measure of past longevity in predicting future longevity. *Received May 2007; revised October 2008. †To contact the author, please e‐mail: [email protected].

To date researchers planning experiments have always lived by the mantra that 'using equal sample sizes gives the best results' and although unequal groups are also used in experimentation, it is not the preferred method of many and indeed actively discouraged in literature. However, during live study planning there are other considerations that we must take into account such as availability of study participants, statistical power and, indeed, the cost of the study. These can all make allocating equal sample (...) sizes difficult, and sometimes near impossible. This, some might say, means that the study would not adhere to rigorous statistical standard (Rosenbaum and Rubin, 1985). However, here we present evidence that, not only is this a false assumption, but that we may actually gain more power in the study by actually using unequal groups. Here, data from a Sepsis Biomarker study is used, in which the aim is to predict, by biomarker level and presence, whether the patient would go on to develop sepsis. It was found that larger control groups may give more power to studies looking for an effect in the mid range but not for large or small effects. This study shows merit in the hypothesis that more power can be achieved when a larger control group is used.

The aging process involves changes in immune regulation, i.e. adaptive immunity declines whereas innate immunity becomes activated. NF‐κB signaling is the master regulator of the both immune systems. Two recent articles highlight the role of the NF‐κB system in aging and immune responses. Adler et al1 showed that the NF‐κB binding domain is the genetic regulatory motif which is most strongly associated with the aging process. Kwon et al2 studying HIV‐1 infection and subsequent immune deficiency process demonstrated that HIV‐1 Tat (...) protein binds to SIRT1 protein, a well‐known longevity factor, and inhibits the SIRT1‐mediated deacetylation of the p65 component of the NF‐κB complex. As a consequence, the transactivation efficiency of the NF‐κB factor was greatly potentiated, leading to the activation of immune system and later to the decline of adaptive immunity. These observations support the scenario where immune responses and aging process can be enforced by the potentiation of NF‐κB transactivation efficiency. Longevity factors, such as SIRT1 and its activators, might regulate the efficiency of the NF‐κB signaling, the major outcome of which is inflamm‐aging via proinflammatory responses.

In assessing the welfare of dairy cows and laying hens, longevity has recently been introduced as an indicator. This paper presents recent attempts to transfer the normative power of longevity to non-human animals and evaluates this choice systematically. It first shows that the normative power of longevity can be justified by utilitarianism but not by rights-based approaches. The case of the ban to kill day-old chicks in Germany is then used to show that public opinion leans neither (...) to the utilitarian approach nor to the rights-based one but draws a firm line between killing animals before and after reaching an adult age. This may be not so much a desire for longevity among farmed animals but a first sign of empathy that may transform our relationship with farmed animals. (shrink)

The evolution and biodiversity of ageing have long fascinated scientists and the public alike. While mammals, including long‐lived species such as humans, show a marked ageing process, some species of reptiles and amphibians exhibit very slow and even the absence of ageing phenotypes. How can reptiles and other vertebrates age slower than mammals? Herein, I propose that evolving during the rule of the dinosaurs left a lasting legacy in mammals. For over 100 million years when dinosaurs were the dominant predators, (...) mammals were generally small, nocturnal, and short‐lived. My hypothesis is that such a long evolutionary pressure on early mammals for rapid reproduction led to the loss or inactivation of genes and pathways associated with long life. I call this the ‘longevity bottleneck hypothesis’, which is further supported by the absence in mammals of regenerative traits. Although mammals, such as humans, can evolve long lifespans, they do so under constraints dating to the dinosaur era. (shrink)

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)

J. Richard Gott III (1993) has used the “Copernican principle” to derive a probability density function for the total longevity of any phenomenon, based solely on the phenomenon’s past longevity. John Leslie (1996) and others have used an apparently similar probabilistic argument, the “Doomsday Argument,” to claim that conventional predictions of longevity must be adjusted, based on Bayes’ Theorem, in favor of shorter longevities. Here I show that Gott’s arguments are flawed and contradictory, but that one of (...) his conclusions—his delta t formula—is mathematically equivalent to Laplace’s famous (and notorious) ‘rule of succession’; moreover, Gott’s delta t formula is a plausible worst-case (if one favors greater longevity) bound in some contexts. On the other hand, the Doomsday Argument is fallacious: the argument’s Bayesian formalism is stated in terms of total duration, but all attempted real-life applications of the argument—with one exception, an application by Gott 1994—actually plug in prior probabilities for future duration; moreover, the Self-Sampling Assumption, an essential premise of the Doomsday Argument, is contradicted by the prior information in all known real-life cases. But rejecting the Doomsday Argument does not entail rejecting the possibility of learning about the future from the past. Applying the work of Bruce M. Hill (1968, 1988, 1993) and Frank P.A. Coolen (1998, 2006) in the field of non-parametric predictive inference, I propose and defend an alternative methodology for quantifying how past longevity of any phenomenon does provide evidence for future longevity. In so doing, I identify an objective standard by which to choose among counting time intervals, counting population, or counting any other measure of past longevity in predicting future longevity. This methodology forms the basis of a calculus of induction. (shrink)

A conception of the person as a subjective being plays a crucial, though frequently overlooked, role in the justification of unequal property in liberal theories. Unger's ascription of individualism to general liberal legal theory can be concretely defended with respect to liberal theories of property. Identifying a common fundamental structure calls in question the conventional view that the liberal legal theories rest on an ensemble of different moral foundations. So important is subjective personality to the moral basis for highly (...) unequal property that such property looks to be morally untenable if this concept of the person is invalid. The analysis points to social theory of personality as a major direction for research into an alternative theory of egalitarian property right. (shrink)

Social circumstances often impinge on later generations in a socio-economic manner, giving children an uneven start in life. Overfeeding and overeating might not be an exception. The pathways might be complex but one direct mechanism could be genomic imprinting and loss of imprinting. An intergenerational "feedforward" control loop has been proposed, that links grandparental nutrition with the grandchild's growth. The mechanism has been speculated to be a specific response, e.g. to their nutritional state, directly modifying the setting of the gametic (...) imprint on one or more genes. This study raises the question: Can overnutrition during a child's slow growth period trigger such direct mechanisms and partly determine mortality?Data were collected by following-up a cohort born in 1905 in Överkalix parish, northernmost Sweden. The probands were characterised by their parents' or grandparents' access to food during their own slow growth period. Availability of food in the area was defined by referring to historical data on harvests and food prices, records of local community meetings and general historical facts. (shrink)

I argue that the Doctrine of Double Effect is accepted because of unreliable processes of belief-formation, making it unacceptably likely to be mistaken. We accept the doctrine because we more vividly imagine intended consequences of our actions than merely foreseen ones, making our aversions to the intended harms more violent, and making us judge that producing the intended harms is morally worse. This explanation fits psychological evidence from Schnall and others, and recent neuroscientific research from Greene, Klein, Kahane, and Schaich (...) Borg. It explains Mikhail and Hauser’s “universal moral grammar” and an interesting phenomenon about Double Effect cases noted by Bennett. When unequally vivid representations determine our decisions, we typically misjudge the merits of our options and make mistakes. So if Double Effect is a product of unequal vividness, it is likely to be mistaken. This argument, I claim, fits Berker’s specifications for good empirically grounded arguments in ethics. (shrink)

This article presents an economic analysis of information good pricing and consumer welfare, and discusses the implications of price discrimination in the information economy. It argues that network externalities, coupled with information asymmetry, enable a dominant marketer to price unequally, extracting late adopters surplus to compensate for the loss from early adopters. In the short term, the minority early adopters benefit by paying less, but in the long term, the majority late adopters suffer by paying more. Considering that late adopters (...) are likely to be at a disadvantage in resources, this discriminatory pricing amounts to the poor subsidizing the rich. Based on this analysis, implications for consumer welfare are discussed. (shrink)

Longevity is valuable. Most of us would agree that it’s bad to die when you could go on living, and death’s badness has to do with the value your life would have if it continued. Most of us would also agree that it’s bad if life expectancy in a country is low, it’s bad if there is high infant mortality and it’s bad if there is a wide mortality gap between different groups in a population. But how can we (...) make such judgments more precise? How should we evaluate the harm of mortality in a population? Although philosophers have written a lot about the harm of death for individuals, very little work has been done on the harm of mortality for populations. In this article, I take the first steps towards developing a theory of the harm of population mortality. Even these first steps, I argue, lead to surprising results. (shrink)

Unequal treatment of human research subjects is a significant ethical concern, because justice in research involving human subjects requires equal protection of rights and equal protection from harm and exploitation. Disputes sometimes arise concerning the issue of unequal treatment of research subjects. Allegedly unequal treatment occurs when subjects are treated differently and there is a genuine dispute concerning the appropriateness of equal treatment. Patently unequal treatment occurs when subjects are treated differently and there is not a (...) genuine dispute about the appropriateness of equal treatment. Allegedly unequal treatment will probably always occur in research with human subjects due to disagreements about fundamental questions of justice. The best way to deal with allegedly unequal treatment is to promote honest and open discussions of the issues at stake. Research regulations can help to minimize patently unequal treatment by providing rules for investigators, ethical review boards, institutions, and sponsors to follow. However, patently unequal treatment may still occur because the regulations are subject to interpretation. Federal agencies have provided interpretive guidance that can help promote consistent review and oversight of human subjects research. Additional direction may be needed on topics that are not adequately covered by current guidance or regulations. International guidelines can help promote equal treatment of human subjects around the globe. While minor variations in the treatment of research subjects should be tolerated and even welcomed, major ones (i.e. those that significantly impact human rights or welfare) should be avoided or minimized.

Graphical AbstractA recent study reported that longevity in Caenorhabditits elegans can be inherited over several generations. This is probably achieved through the following epigenetic mechanism: inherited demethylated histones at some central loci, such as miRNA, transcription factors or signaling regulators affect the expression of certain genes leading to the longevity phenotype.

Is the United States "the land of equal opportunity" or is the playing field tilted in favor of those whose parents are wealthy, well educated, and white? If family background is important in getting ahead, why? And if the processes that transmit economic status from parent to child are unfair, could public policy address the problem? Unequal Chances provides new answers to these questions by leading economists, sociologists, biologists, behavioral geneticists, and philosophers.New estimates show that intergenerational inequality in the (...) United States is far greater than was previously thought. Moreover, while the inheritance of wealth and the better schooling typically enjoyed by the children of the well-to-do contribute to this process, these two standard explanations fail to explain the extent of intergenerational status transmission. The genetic inheritance of IQ is even less important. Instead, parent-offspring similarities in personality and behavior may play an important role. Race contributes to the process, and the intergenerational mobility patterns of African Americans and European Americans differ substantially.Following the editors' introduction are chapters by Greg Duncan, Ariel Kalil, Susan E.

Exploring the cultural politics of diasporic entrepreneurs and migrant labourers through an examination of Chinese restaurants in Johannesburg, this article presents what I call the “intra-migrant economy” amid everyday racialized insecurities in urban South Africa. I use the term “intra-migrant economy” to refer to the employment of one group of migrants by another group of migrants as an economic strategy outside the mainstream labour market. These two groups of migrants work in the same industry, live in the same city, and (...) have established a sort of unequal employment relation that can be hierarchical and interdependentat once. Chinese migrants are socially marginalized but not economically underprivileged, which stands in contrast to Zimbabwean migrants, who remain economically underprivileged even though they speak local languages. Their different socioeconomic positions in South Africa are profoundly influenced by their nationality and racialization. Thisanalysis of their interdependency focuses on the economic and political structures that shaped the underlying conditions that brought Chinese and Zimbabwean migrants to work together in South Africa.

In this paper, we respond to Andrew Avins's recent review of methods whose use he advocates in clinical trials, to make them more ethical. He recommends in particular, “unbalanced randomisation”. However, we argue that, before such a recommendation can be made, it is important to establish why unequal randomisation might offer ethical advantages over equal randomisation, other things being equal. It is important to make a pragmatic distinction between trials of treatments that are already routinely available and trials of (...) restricted treatments. We conclude that unequal randomisation could, indeed, be an ethical compromise between protecting the interests of participants and those of society. (shrink)

In 2009 the Roundtable on Sustainable Palm Oil established a conflict resolution mechanism to help rural communities address their grievances against palm oil companies that are RSPO members. This article presents the broadest ever comprehensive assessment of the use and effectiveness of the RSPO conflict resolution mechanism, providing both overviews and in-depth analysis. Our central question is: to what extent does the RSPO conflict resolution mechanism offer an accessible, fair and effective tool for communities in Indonesia to resolve conflicts with (...) companies? Our aim is not only to provide a ‘reality check’ of this mechanism but also to contribute to the wider debate on how communities can seek access to justice when engaged in intractable conflicts with palm oil companies. For data collection, we took three steps. First, we used our own database of 150 conflicts between communities and companies in Indonesia. We identified 64 conflicts that involved RSPO member companies, of which 17 prompted communities to convey their grievances to the RSPO’s conflict resolution mechanism. Second, we used the database of the RSPO, which handled 85 complaints against companies in Indonesia in the period 2009–2020. Third, we conducted fieldwork, in total, about 6 months of fieldwork and extensive interviews on three conflicts involving RSPO companies to identify mechanisms leading to both failed and successful instances of conflict resolution. For our assessment, we used three criteria to assess the conflict resolution mechanism of the RSPO: accessibility, procedural justice, and the outcomes of the process. We conclude that—on all counts—the conflict resolution mechanism is biased in favor of companies. The result of these biases is that the actual capacity of the RSPO’s mechanism to provide a meaningful remedy for rural communities’ grievances remains very limited. This unequal access to justice sustains conflicts between companies and communities over land. (shrink)

Randomised clinical trials provide the most valid means of establishing the efficacy of clinical therapeutics. Ethical standards dictate that patients and clinicians should not consent to randomisation unless there is uncertainty about whether any of the treatment options is superior to the others ("equipoise"). However, true equipoise is rarely present; most randomised trials, therefore, present challenging ethical dilemmas. Minimising the tension between science and ethics is an obligation of investigators and clinicians. This article briefly reviews several techniques for addressing this (...) issue and suggests that unbalanced randomisation, a technique rarely employed in current clinical trial practice, may be useful for enhancing the ethical design of human experimentation.

The first National Health Service (NHS) was introduced in the United Kingdom providing free universal health care (UHC) at the point of use. Within decades, increasing European countries adopted the same intervention to improve the health of citizens on the entire life span.

Preserving solidarity from the pressure of modern (...) medicine and society needs to identify a fair and sustainable type of coverage at the same time. This paper aims (1) to describe the short circuit of solidarity in European NHSs; (2) to discuss alternative versions of UHC and support redistributive neo-universalism; (3) to promote the role of medical humanities in implementing this solution.

Despite recommendations from the Cartwright Report ethical review by health ethics committees has continued in New Zealand without health practitioners ever having to acknowledge their dual roles as health practitioners researching their own patients. On the other hand, universities explicitly identify doctor/research-patient relations as potentially raising conflict of role issues. This stems from the acknowledgement within the university sector itself that lecturer/research-student relations are fraught with such conflicts. Although similar unequal relationships are seen to exist between health researchers and (...) their patients, the patient/subjects are not afforded the levels of protection that are afforded student/subjects. In this paper we argue that the difference between universities and health research is a result of the failure of the Operational Standard Code for Ethics Committees to explicitly acknowledge the vulnerability of the patient and conflict of interests in the dual roles of health practitioner/researcher. We end the paper recommending the Ministry of Health consider the rewriting of the Operational Standard Code for Ethics Committees, in particular in the rewriting of section 26 of the Operational Standard Code for Ethics Committees. We also identify the value of comparative ethical review and suggest the New Zealand's Health Research Council's trilateral relationship with Australia's NHMRC (National Health and Medical Research Council) and Canada's CIHR (Canadian Institute of Health Research) as a useful starting point for such a process.

Morin has written a rich and valuable book. Its main aim is to isolate the factors involved in maintaining behavioural lineages over time, and to understand how these factors might interact. In doing so, it takes issue with the abstract and idealised models and arguments of dual-inheritance theorists, which are alleged in this account to rely on an overly simplistic notion of imitative learning. Morin’s book is full of ethnographic, anthropological, and psychological research, and there is much to commend in (...) it. However, Morin’s arguments against the dual-inheritance theorists are less convincing when put under scrutiny, and his positive picture which includes appeals to ostensive communication, intrinsic appeal and cultural attraction has some difficulties. I argue that when we contrast dual-inheritance theorists and Morin, we find that there may be fewer differences and greater commonalities than Morin’s book might suggest. (shrink)
