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)

Boredom has dominated discussions about longevity thanks to Bernard Williams’s influential “The Makropulos Case.” I reveal the presence in that paper of a neglected, additional problem for the long-lived person, namely alienation in the face of unwanted change. Williams gestures towards this problem but does not pursue it. I flesh it out on his behalf, connecting it to what I call the ‘curmudgeonly attitude to change.’ This attitude manifests itself in the tendency, amongst those getting on in years, to (...) observe that things are getting worse. Curmudgeonliness is typically met with dismissal because it often concerns changes that don’t radically inhibit the curmudgeon’s well-being or autonomy. I believe that taking the curmudgeonly attitude more seriously will provide insight into the longer-lived self and its relation to the future. Using Williams’s approach to longevity as the framework, I contend that—as with boredom—a sense of alienation born of curmudgeonliness can become terminal for the subject, rendering her unable to envision the future as a site of worthwhile activity. However, I also uncover ways in which this agential stasis is significantly distinct from boredom and constitutes a different worry and a different risk for the long-lived individual. (shrink)

This paper represents an attempt to correlate the concept of hope with the notion of human longevity and reflects the actual debates around the problem of life extension. Our analysis combines ideas from philosophy, sociology, bioethics, and religion to illustrate the problem of longevity in the context of biomedical and technological progress, and - at the same time - to show the (possible) consequences of prolonging life over the human body limits. Extending human life through emerging technologies is (...) much closer to us than we might think and is a particularly challenging topic. (shrink)

Populations in developed societies are rapidly aging: fertility rates are at all-time lows while life expectancy creeps ever higher. This is triggering a social crisis in which shrinking youth populations are required to pay for the care and retirements of an aging majority. Some people argue that by investing in the right kinds of lifespan extension technology – the kind that extends the healthy and productive phases of life – we can avoid this crisis (thereby securing a ‘longevity dividend’). (...) This chapter argues that this longevity dividend is unlikely to be paid if lifespan extension coincides with rampant technological unemployment. This does not mean that we should not pursue lifespan extension, but it does mean that the argument in its favor needs to rest on other grounds. After articulating these grounds, the chapter proceeds to consider the implications this has for our vision of the extended life, postwork utopia. It argues that this vision may need to be reconceived and suggests that one plausible reconception involves prioritizing the role of games in the well-lived life. (shrink)

When considering the social valuation of a life-year, there is a conflict between two basic intuitions: on the one hand, the intuition of universality, according to which the value of an additional life-year should be universal, and, as such, should be invariant to the context considered; on the other hand, the intuition of complementarity, according to which the value of a life-year should depend on what this extra-life-year allows for, and, hence, on the quality of that life-year, because the quantity (...) of life and the quality of life are complement to each other. This paper proposes three distinct accounts of the intuition of universality, and shows that those accounts either conflict with a basic monotonicity property, or lead to indifference with respect to how life-years are distributed within the population. Those results support the abandon of the intuition of universality. But abandoning the intuition of universality does not prevent a social evaluator from giving priority, when allocating life-years, to individuals with the lowest quality of life. (shrink)

Taking people’s longevity as a measure of good life, humankind can proudly say that the average person is living a much longer life than ever before. The AIDS epidemic has however for the first time in decades stalled and in some cases even reverted this trend in a number of countries. Climate change is increasingly becoming a major challenge for food security and we can anticipate that hunger caused by crop damages will become much more common. -/- Since many (...) of the challenges humanity faced in the past were overcome by inventive solutions coming from the life sciences, we are compelled to reconsider how we incentivize science and technology development so that those in need can benefit more broadly from scientific research. There is a huge portion of the world population that is in urgent need for medicines to combat diseases that are currently neglected by the scientific community and could immensely benefit from agricultural research that specifically targets their environmental conditions. At the same time efforts have to be made to make the fruits of current and future research more widely accessible. These changes would have to be backed by a range of moral arguments to attract people with diverging notions of global justice. This article explores the main ethical theories used to demand a greater share in the benefits from scientific progress for the poor. Since life sciences bring about a number of special concerns, a short list of conflictive issues is also offered. (shrink)

According to the Value-Neutrality Thesis, technology is morally and politically neutral, neither good nor bad. A knife may be put to bad use to murder an innocent person or to good use to peel an apple for a starving person, but the knife itself is a mere instrument, not a proper subject for moral or political evaluation. While contemporary philosophers of technology widely reject the VNT, it remains unclear whether claims about values in technology are just a figure of speech (...) or nontrivial empirical claims with genuine factual content and real-world implications. This paper provides the missing argument. I argue that by virtue of their material properties, technological artifacts are part of the normative order rather than external to it. I illustrate how values can be empirically identified in technology. The reason why value-talk is not trivial or metaphorical is that due to the endurance and longevity of technological artifacts, values embedded in them have long-term implications that surpass their designers and builders. I further argue that taking sides in this debate has real-world implications in the form of moral constraints on the development of technology. (shrink)

The practice of ‘management euthanasia’, in which zoos kill otherwise healthy surplus animals, is a controversial one. The debate over the permissibility of the practice tends to divide along two different views in animal ethics—animal rights and animal welfare. Traditionally, those arguments against the practice have come from the animal rights camp, who see it as a violation of the rights of the animal involved. Arguments in favour come from the animal welfare perspective, who argue that as the animal does (...) not suffer, there is no harm in the practice and it is justified by its potential benefits. Here, I argue that an expansion of the welfare view, encompassing longevity and opportunities for positive welfare, give stronger considerations against management euthanasia, which then require greater benefits to justify its use.

There is a certain metaphor that has enjoyed tremendous longevity in the evolution of ageing literature. According to this metaphor, nature has a certain goal or purpose, the perpetuation of the species, or, alternatively, the reproductive success of the individual. In relation to this goal, the individual organism has a function, job, or task, namely, to breed and, in some species, to raise its brood to maturity. On this picture, those who cannot, or can no longer, reproduce are somehow (...) invisible to, or even dispensable to, the evolutionary process. Here, I argue that the metaphor should be discarded, not on the grounds that it is a metaphor, but on the grounds that this particular metaphor distorts our understanding of the evolution of ageing. One reason the metaphor is problematic is that it frames senescence and death as nature’s verdict on the value of older individuals. Instead, we should explore a different metaphor: the lengthy post-reproductive period in humans and some other animals is not an accident of culture, but designed by nature for the purpose of supporting and guiding younger generations. On this alternate picture, different stages of life have their own evolutionary rationales, their distinctive design features, their special mandates. (shrink)

The paper presents the concept of the "silver economy" as an economic system related to population aging and underlines the features of this policy idea. The study first introduces the discourse and stages of constructing this system by international and national public policy actors in aging. Next, a critical analysis of the dimensions and areas of implementation and development of the silver economy as a policy concept was carried out as well as a review of its external and internal limitations. (...) The conclusion contains proposals for further research directions. (shrink)

This chapter focuses on AI-based cognitive and perceptual enhancements. AI-based brain enhancements are already under development, and they may become commonplace over the next 30–50 years. We raise doubts concerning whether radical AI-based enhancements transhumanists advocate will accomplish the transhumanists goals of longevity, human flourishing, and intelligence enhancement. We urge that even if the technologies are medically safe and are not used as tools by surveillance capitalism or an authoritarian dictatorship, these enhancements may still fail to do their job (...) for philosophical reasons. In what follows, we explore one such concern, a problem that involves the nature of the self. We illustrate that the so called transhumanist efforts to “merge oneself with AI” could lead to perverse realizations of AI technology, such as the demise of the person who sought enhancement. And, in a positive vein, we offer ways to avoid this, at least within the context of one theory of the nature of personhood. (shrink)

The physicist J. Richard Gott has given an argument which, if good, allows one to make accurate predictions for the future longevity of a process, based solely on its present age. We show that there are problems with some of the details of Gott's argument, but we defend the core thesis: in many circumstances, the greater the present age of a process, the more likely a longer future duration.

Enlightenment values are built around the presumption of an independent rational self, citizen, consumer and pursuer of self-interest. Even the authoritarian and communitarian variants of the Enlightenment presumed the existence of autonomous individuals, simply arguing for greater weight to be given to their collective interests. Since Hume, however, radical Enlightenment empiricists have called into question the existence of a discrete, persistent self. Today neuroscientific reductionism has contributed to the rejection of an essentialist model of personal identity. Contemporary transhumanism has yet (...) to grapple with the radical consequences of the erosion of liberal individualism on their projects of individually chosen enhancement and longevity. Most transhumanists still reflect an essentialist idea of personal identity, even as they embrace projects of radical cognitive enhancement that would change every constituent element of consciousness. Transhumanists need to grapple with how their projects and ethics would change if personal identity is an arbitrary, malleable fiction. (shrink)

Richard Dawkins tries to establish an analogy between computer viruses and theistic belief systems, analyzing the latter in terms of his concept of the meme. The underlying thrust of Dawkins' argument is to downplay the role of truth and logic in the survival of theories and to emphasize humankind's helpless liability to incurable infection by doctrines that Dawkins regards as absurd. Dawkins supplies a list of "symptoms” of mind-infection. However, on closer investigation these characteristics are found to be either rather (...) weak protection against criticism or quite virtuous. Dawkins relies on a crude justificationism that could just as well be called a mind-virus. Applying Dawkins’ own selection of the general characteristics of a good meme protector and propagator leads to the conclusion that his particular theistic examples would actually impair copyability. -/- Scientific theories are better examples of memes with high longevity, fecundity, and fidelity. A Darwinian analysis of wishful and fearful thinking as useful to hypotheses-testing and goal-seeking organisms undermines Dawkins' attribution of absolute irrational stubbornness to theists. To counterbalance Dawkins' emphasis on the propagation of the absurd, I rehabilitate the Socratic emphasis on the importance of truth and logic in rhetoric, interpreted broadly as the theory of the successful propagation of a message. I use Popper's notion of situational analysis, and an evolutionary perspective to argue that rational standards of a message enhance its copyability. I further apply Popper’s notions of World 3, 2, and 1 to memes; this helps us see the perpetuation of a doctrine as a logical task. (shrink)

Metaphysics as an independent discipline has a surprisingly short history. Until the early eighteenth century, many, perhaps even most, writers on “metaphysics” primarily had the eponymous work of Aristotle in mind. In the writings of the early eighteenth-century German rationalists—Christian Wolff and Alexander Baumgarten—we find a conception of metaphysics that is no longer necessarily tied to Aristotle’s great work. But metaphysics as a discipline was not blessed with longevity, as a dozen years or so before Louis XVI it was (...) condemned to the guillotine by Kant’s first critique. The fate of metaphysics after the Kantian revolution is a story that still needs to be told, but it would be fair to say, I think, that for the past two centuries engagement with heavy metaphysical concepts such as eternity has been taken to be either a form of backwardness (religious or otherwise) or a kind of eccentricity. Luckily, things seem to have changed somewhat over the past twenty years. Suddenly, for example, we are seeing debates about monism appear in mainstream journals. (This could hardly be imagined in the 1970s or 1980s.) The emergence of interest in metaphysical monism as well as the persistent engagement with the philosophy of modality may open a window of opportunity through which eternity could again take her rightful seat as a fundamental notion of metaphysics.

Scientists have been arguing for more than 25 years about whether it is a good idea to collect voucher specimens from particularly vulnerable biological populations. Some think that, obviously, scientists should not be harvesting organisms from, for instance, critically endangered species. Others think that, obviously, it is the special job of scientists to collect precisely such information before any chance of retrieving it is forever lost. The character, extent, longevity, and span of the ongoing disagreement indicates that this is (...) likely to be a hard problem to solve. Nonetheless, the aim of this paper is to help field biologists figure out what do to when collecting a voucher specimen risks extinction. Here I present and assess varying practices of specimen collection for both extant and extinct species in order to compare and contrast cases where extinction risk both is and is not a problem. When it comes to taking vouchers from extant species at some risk of extinction, I determine that those advocating for conservative approaches to collection as well as those advocating for liberal information-gathering practices have good reasons to assess things in the way they each do. This means that there is unlikely to be a decisive, one-size-fits-all response to this problem. Still, progress can be made. We can acknowledge the risks of proceeding in either manner, as well as the uncertainty about how best to proceed. We can proceed as thoughtfully as possible, and be ready to articulate a rationale for whichever procedure is used in any particular case. (shrink)

This essay explores the intersection of racism, racial embodiment theory and the recent hostility aimed at immigrants and foreigners in the United States, especially the targeting of people of Latin American descent and Latino/as. Anti-immigrant and anti-foreigner sentiment is racist. It is the embodiment of racial privilege for those who wield it and the materiality of racial difference for those it is used against. This manifestation of racial privilege and difference rests upon a redrawing of the color line that is (...) meant towards preserving exclusive categories of political membership. The charge of racism, however, is elided by the fact that this hostility takes the form of a specious embracement of law and lawfulness. “Illegal” in this sense not only captures the actions of those who enter the United States through clandestine or informal means, but, in light of the history of immigration and citizen- ship law, the term operates as a racial trope that designates non-white status, thus marginalizing and alienating certain immigrants from ongoing nation-formation processes. I explain the source for anti-immigrant hostility in the United States, which I take to be connected to the longevity of white normativity as the basis for American identity. I then critically assess how the idea of national belonging is crucial to the perpetuation of white-ways-of-being, especially when citizenship has historically been a venue for the embodiment of racial and even colonial privilege. I conclude by posing several questions about the nature of racial identities and racism that suggest new avenues for further research on racial embodiment in a “postracial” era. pp. 65–90. (shrink)

Three separate churches erected in Constantinople were all dedicated to the wisdom of Christ and erected on the same site one after the other. These churches were built between 360 and 537 AD by three different emperors: Constantius II, Theodosius the Younger, and Justinian I. The first two churches were consumed in flames after relatively short lives, but the final and greatest church still stands today, despite a history of extensive damage. This final edifice is the main focus of this (...) paper, owing to its 1500 year longevity and unprecedented architecture. If the entire History of Justinian's church is to considered, it is inaccurate to refer to it as a “church,” because although it remained a church for the first 900 years after its audacious construction, it was later converted into a mosque. Today it is a museum, in remembrance of its long history. (24). (shrink)

Concrete is one of the most intelligent and widely utilized man-made materials in the construction industry. Despite this, even high-quality concrete is susceptible to porosity, which reduces its serviceability period. Furthermore, there is an increasing need to increase longevity due to environmental exposure such as soil moisture, corrosive outside elements, or structural defects forming in the surface of concrete. The use of crystalline admixtures in concrete is one of the many approaches to reducing these risks. When crystalline admixtures come (...) into contact with water, they form thin crystals that fill pores, capillaries, and micro fractures, as a result making concrete a self-sealing material. When the concrete has dried, the crystalline particles remain dormant until they come into contact with additional water, which causes them to crystallize once more. This research aims to analyze and compare the material properties of commonly used concrete and concrete where crystalline waterproofing is present. Furthermore, experiments are conducted to evaluate each of the concrete samples: compressive strength, water permeability, and flexure strength. As a result, demonstrating the benefits or negative aspects of the use of crystalline admixture in the early stages of concrete is important. It is not yet defined, whether this is the future of cutting-edge concrete and the impact that it will have in the Albanian building market. (shrink)

The perennial nature of some of philosophy’s deepest problems is a puzzle. Here, one problem, the realism–anti-realism debate, and one type of explanation for its longevity, are examined. It is argued that realism and anti-realism form a dialetheic pair: While they are in fact each other’s logical opposite, nevertheless, both are true (and both false). First, several reasons why one might think such a thing are presented. These reasons are merely the beginning, however. In the following sections, the dialetheic (...) conclusion is directly argued for by showing how realism and anti-realism satisfy Priest’s “inclosure schema”. In the last section and the conclusion, the conscious mind’s role in creating realism and anti-realism is discussed. This role further supports the conclusion that realism and anti-realism form a dialetheic pair. (shrink)

Jean-Claude Milner’s Le sage trompeur (2013), a controversial recent piece of French Spinoza literature, remains regrettably understudied in the English-speaking world. Adopting Leo Strauss’ esoteric reading method, Milner alleges that Spinoza dissimulates his genuine analysis of the causes of the persecution and survival of the Jewish people within a brief “manifesto” found at the end of the Tractatus Theologico-Politicus (TTP), Chapter 3. According to Milner, Spinoza holds that the Jewish people themselves are responsible for the hatred of the Jewish people, (...) and that the engine of their longevity is the hatred they engender. Additionally, claims Milner, Spinoza covertly insinuates that the solution to this persistent state of hatred consists in the mass apostasy of the Jewish people under the leadership of a Sabbatai Zevi-like figure. This article presents the Milner–Spinoza controversy to the English-speaking public along with the larger context of French-language scholarship on Spinoza’s relation to Judaism. While refuting Milner’s reading of Spinoza, I simultaneously clarify relevant elements of Spinoza’s discussions of Judaism in the TTP, such as Spinoza’s examination of Jewish identity and the nature of divine election, Spinoza’s understanding of the causes of national hatred, and Spinoza’s appeals to Portuguese, Spanish, Chinese, and Turkish political history.

Gerontology together with its subfields, such as social gerontology, geragogy, educational gerontology, political gerontology, environmental gerontology, and financial gerontology, is still a relatively new academic discipline that is currently intensively developing, expanding research fields and combining various theoretical and practical perspectives. The interdisciplinarity, transdisciplinarity, and multidisciplinarity of research on ageing and old age, despite its vast thematic, methodological and theoretical diversity, have a common denominator, which is the focus of research work on improving the quality of life of older people. (...) It is the concern for the components of quality of life such as welfare and well-being as well as focus on learning about phenomena conditioning successful ageing that has become motivators and premises hidden or visible in many texts included in the Research Topic “Perspectives and Theories of Social Innovation for Ageing Population.” The Research Topic that we are presenting to our readers is unique not only because of its size but above all because of its novelty and social involvement, visible in the content of individual chapters. The presented collection includes 17 articles prepared in total by 76 authors from the following countries: China, Finland, Germany, Ghana, Hungary, Ireland, Israel, Italy, Japan, the Netherlands, Poland, Portugal, Slovenia, Spain, Sweden, the United Kingdom, and the United States. Two journals were combined with this Research Topic: “Frontiers in Public Health” and “Frontiers in Sociology.” The presented Research Topic contains seven types of articles covering: two community case studies, eight original research articles, two perspective articles, one hypothesis and theory paper, one policy and practice review, one methods article, and two book reviews. The rationale to start work on this set of texts was the desire to continue and deepen the research analyses of the editors of this set, which concern the development of social innovations for the ageing population as well as changes of public policy on ageing. This Research Topic deals with topics covering issues such as social learning, intergenerational transmission, senior entrepreneurship, creative content creation by older adults, care services, raising the independence of older people in their living environments, dementia challenges, the image of the older generation in local social policies, new trends in qualitative research on old age, strategies for dealing with chronic diseases, the use of digital tools in health education, the silver economy/longevity economy, age-friendly environments, the diversity of structures and social services, preparation for old age, and food safety. The wide variety of submitted texts shows several selected and, according to the authors, current challenges that contemporary seniors have to face. The articles comprising this Research Topic are organized according to five themes. (shrink)

Human augmentation is discussed in three axes: the technological means, the ability being augmented, and the social systems that will be affected. The technological augmentations considered range from exocortical information and communication systems, to pharmaceuticals, tissue and genetic engineering, and prosthetic limbs and organs, to eventually nanomedical robotics, brain-computer interfaces and cognitive prostheses. These technologies are mapped onto the capabilities which we are in the process of enabling and augmenting, which include extending longevity and physical, sensory and cognitive abilities, (...) and enabling control over emotions, moral behavior, and spiritual experience. The impacts of augmentation on the family, education, economy, politics and religion are considered individually, but their aggregate effects will be non-linear and drive complex adaptations in the living machine that is our co-evolved techno-social civilization.

Financial gerontology can be defined as investigating relations between finances and aging. Authors such as Neal E. Cutler, Kouhei Komamura, Davis W. Gregg, Shinya Kajitani, Kei Sakata, and Colin McKenzie affirm that financial literacy is an effect of aging with concern about the issue of finances, as well as stating that it is the effect of longevity and aging on economies or the financial resilience of older people.

In this paper, I will provide an interpretation of Foucauldian theoretical understanding on natures of power from sovereign power to biopolitics. In order to give further depth and texture to what he means by biopolitics, I will attempt to connect biopolitics with his earlier work Discipline and Punish. The term ‘biopolitics’ was actually mentioned by Foucault on the last chapter of his History of Sexuality Volume 1: An Introduction, where he also claimed it as a technology of power linked to (...) biopower. Foucault wrote that the highest function of biopolitics is not to kill, but to invest life through and through in the machineries of production. If that is the case, then, biopolitics aims to ensure the longevity, health, and wellness of the social bodies. However, if biopolitics is the politics that safeguard life, how come that the innumerable individuals are situated in dire condition? To answer this question, the work of Antonio Negri and Michael Hardt will be used to understand further the nature of biopolitics and its effects in the social terrain specially in the contemporary society.

The utilitarian calculators of genetic therapy would do well to reflect again on Mills' liberal democratic rules of thumb: utility will generally be maximized when people are free to make choices, with good information, good instruments of collective action (democracy), and relative equality. My rule of thumb is that if we give future generations genetic choices, they will generally choose health, happiness, intelligence, and longevity, for themselves and their descendants.

In this paper, we focus on the most efficacious AI applications for life extension and anti-aging at three expected stages of AI development: narrow AI, AGI and superintelligence. First, we overview the existing research and commercial work performed by a select number of startups and academic projects. We find that at the current stage of “narrow” AI, the most promising areas for life extension are geroprotector-combination discovery, detection of aging biomarkers, and personalized anti-aging therapy. These advances could help currently living (...) people reach longevity escape velocity and survive until more advanced AI appears. When AI comes close to human level, the main contribution to life extension will come from AI integration with humans through brain-computer interfaces, integrated AI assistants capable of autonomously diagnosing and treating health issues, and cyber systems embedded into human bodies. Lastly, we speculate about the more remote future, when AI reaches the level of superintelligence and such life-extension methods as uploading human minds and creating nanotechnological bodies may become possible, thus lowering the probability of human death close to zero. We suggest that medical AI based superintelligence could be safer than, say, military AI, as it may help humans to evolve into part of the future superintelligence via brain augmentation, uploading, and a network of self-improving humans. Medical AI’s value system is focused on human benefit. (shrink)

The precarious rights of senior citizens, especially those who are highly educated and who are expected to counsel and guide the younger generations, has stimulated the creation internationally of advocacy associations and opinion leader groups. The strength of these groups, however, varies from country to country. In some countries, they are supported and are the focus of intense interest; in others, they are practically ignored. For this is reason we believe that the creation of a network of all these associations (...) is essential. The proposed network would act as a support for the already-existing policies of the United Nations’ High Commission for Human Rights, of independent experts, and of the Global Alliance for the Rights of Older People. All three have long ago recommended the creation of a recognized instrument for uniting presently scattered efforts. The proposed network, therefore, will seek to promote the international exchange of relevant expertise, and it will reinforce the commitments and actions that single countries are currently taking to meet these objectives. For example, informative public events can be organised to promote particular support initiatives and to provide an opportunity for new members of the network to be presented. The network will promote health for senior citizens, disease prevention, senior mobility, safe free time for seniors, alimentary education, protection against new risks and dangers, as well as equity in the services necessary for seniors to adopt new information and communication technologies. In the case of retired academic members, the network will promote equality with respect to continuing use of digital technologies (particularly email), continuing access to research libraries, and the guaranteed ability for seniors to fund their own research programs and to deliver free seminars.

This paper analyses three centuries of developing German-language philosophy journals, from the first journals published in 1665 to those from the first decade of post-WWII recovery. Relying upon two bibliographies of philosophical journals collected in the 1970s, one by Joachim Kirchner and one by Wolfram Hogrebe, Rudolf Kamp, and Gert König, we attained a dataset of 607 journals. To analyse the population of periodicals, we identified three key components: the longevity of each journal and the growth rate and the (...) continuity of the body of the journal population. The most puzzling finding is that there was a rapid growth in the number of journals at the end of the eighteenth century followed by a long decline in numbers that lasted almost a century. This paper analyses the structure of the boom in philosophical periodicals after 1888, followed by the effects of both World Wars, and identifies the communication crisis that occurred at the height of the Weimar Republic.

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

This chapter investigates older people’s needs in contemporary Ghana using the analyses of quantitative and qualitative data sets. The findings identified eight distinct patterns of needs, namely basic needs, care, and domestic help; sociability, emotional and affective support; information; counseling; spiritual needs, free bus rides, and rights. These needs highlight older adults’ social and personal requirements regarding daily living and healthcare in their desire to age with dignity. Their provision may avert problems related to population ageing, including old-age dependency. These (...) needs can be addressed through the following measures. First, the facilitation of the informational needs of older people is attainable through the introduction of initiation for adults and/or older people into the social structure and/or life course. Second, the provision of houses through the mediation of government on behalf of pension contributors, payable in installments. These may ensure appropriate adjustment to life in old age, albeit longevity. The life-sustaining needs of older people have existed since time immemorial. However, these needs are now taking a new dimension in the era of population ageing and increased life expectancy, economic hardships, and weakening extended family support system. We, therefore, argue that these require interventions at both the family and institutional or state levels or formal and informal levels, particularly needs satisfying programs and policies should be instituted by the government in addition to the existing ones.

Serial Endosymbiosis Theory, or SET, was conceived and developed by Lynn Margulis, to explain the greatest discontinuity in the history of life, the origin of eukaryotic cells. Some predictions of SET, namely the origin of mitochondria and chloroplasts, withstood the test of the most recent evidence from a variety of disciplines including phylogenetics, biochemistry, and cell biology. Even though some other predictions fared less well, SET remains a seminal theory in biology. In this paper, I focus on two aspects of (...) SET. First, using the concept of "universal symbiogenesis”, developed by Freeman Dyson to search for commonalities in astronomy and biology, I propose that SET can be extended beyond eukaryogenesis. The extension refers to the possibility that even prokaryotic organisms, themselves subject to the process of symbiogenesis in SET, could have emerged symbiotically. Second, I contrast a recent “viral eukaryogenesis” hypothesis, according to which the nucleus evolved from a complex DNA virus, with a view closer to SET, according to which the nucleus evolved through the interplay of the archaeal host, the eubacterial symbiont, and a non-LTR transposon, or telomerase. Viruses joined in later, through the process of viral endogenization, to shape eukaryotic chromosomes in the process of karyotype evolution. These two proposals based on SET are a testament to its longevity as a scientific theory. (shrink)
