This paper motivates an account of knowledge as a social kind, following a cue by Edward Craig, which captures two major insights behind social and feminist epistemologies, in particular our epistemic interdependence concerning knowledge and the role of social regulative practices in understanding knowledge.

Traditionally, this puzzle has been solved in various ways. Aristotle, for example, distinguished between “accidental” and “essential” changes. Accidental changes are ones that don't result in a change in an objects' identity after the change, such as when a house is painted, or one's hair turns gray, etc. Aristotle thought of these as changes in the accidental properties of a thing. Essential changes, by contrast, are those which don't preserve the identity of the object when it changes, such as when (...) a house burns to the ground and becomes ashes, or when someone dies. Armed with these distinctions, Aristotle would then say that, in the case of accidental changes, (1) and (2) are both false—a changing thing can really change one of its “accidental properties” and yet literally remain one and the same thing before and after the change.

This paper defends a principle I call Equal Treatment, according to which the rationality of a belief is determined in precisely the same way as the rationality of any other state. For example, if wearing a raincoat is rational just in case doing so maximizes expected value, then believing some proposition P is rational just in case doing so maximizes expected value. This contrasts with the popular view that the rationality of belief is determined by evidential support. It also contrasts (...) with the common idea that in the case of belief, there are two different incommensurable senses of rationality, one of which is distinctively epistemic. I present considerations that favor Equal Treatment over these two alternatives, reply to objections, and criticize some arguments for Evidentialism. I also show how Equal Treatment opens the door to a distinctive kind of response to skepticism. (shrink)

Psychopathological delusions have a number of features that are curiously difficult to explain. Delusions are resistant to counterevidence and impervious to counterargument. Delusions are theoretically, affectively, and behaviorally circumscribed: delusional individuals often do not act on their delusions and often do not update beliefs on the basis of their delusions. Delusional individuals are occasionally able to distinguish their delusions from other beliefs, sometimes speaking of their “delusional reality.” To explain these features, I offer a model according to which, contrary to (...) appearances, delusions are not beliefs at all. Delusions are acceptances that are generated by pathologically powerful cognitive feelings. This model has implications for the way that we should think about non-pathological doxastic states and emotions. (shrink)

Many believe that values are crucially dependent on emotions. This paper focuses on epistemic aspects of the putative link between emotions and value by asking two related questions. First, how exactly are emotions supposed to latch onto or track values? And second, how well suited are emotions to detecting or learning about values? To answer the first question, the paper develops the heuristics-model of emotions. This approach models emotions as sui generis heuristics of value. The empirical plausibility of the heuristics-model (...) is demonstrated using evidence from experimental psychology, evolutionary anthropology and neuroscience. The model is used then to answer the second question. If emotions are indeed heuristics of value, then it follows that emotions can be an important and useful source of information about value. However, emotions will not be epistemically superior in the sense of being the highest court of appeal for the justification of axiological beliefs (the latter view is referred to as the Epistemic Dependence Thesis, or EDT for short). The paper applies the heuristics-model to celebrated cases from the philosophy of emotions literature arguing that while the heuristics-model offers a good explanation of typical patterns of emotional reactions in such cases, advocates of EDT will have a hard time accounting for these patterns. The paper also shows that the conclusions drawn from special cases generalize. The paper ends by arguing that skepticism about the metaethical significance of emotions is compatible with a commitment to the importance of emotions in first-order normative ethics. (shrink)

This paper outlines and defends a notion of tragic-remorse. This moral emotion properly accompanies those actions that involve unavoidable moral wrongdoing in general and dirty hands scenarios in particular. Tragic-remorse differs both phenomenologically and conceptually from regret, agent-regret and remorse. By recognising the existence of tragic-remorse, we are better able to account for our complex moral reality which at times makes it necessary for good persons to act in ways that although justified leave the agent with a moral stain and (...) a particular emotional response.

Adult education has long been the Cinderella of the education system. This is not helped by the fact that there is currently an impasse between employers, government and individuals over who should finance such training. So what, if anything, can philosophers do to help resolve the normative question of who ought to pay, setting aside for the moment the practical question of how this might be put into effect? An important strand of contemporary egalitarian philosophy argues that equality of opportunity (...) for education should be implemented in such a way that children with the same level of talent and the same willingness to make an effort have the same opportunity to attain skills and qualifications such that they are each able to compete effectively with others for advantageous positions and rewards in society. But what about children or teenagers who drop out of education or make such little effort that they achieve wholly inadequate exam results? Should they be offered second and third chances for free education as adults funded by the state? A case is made for lifelong as opposed to one‐off equality of opportunity for education on a number of grounds, including efficiency, utility, the value of choice, the social bases of self‐respect and responsibility‐catering prioritarianism. This last view supports lifelong access to education but with the additional stipulation that adults should contribute at least some of the costs themselves in so far as they are accountable for not making enough effort the first time around.

Circumscribed delusional beliefs can follow brain injury. We suggest that these involve anomalous perceptual experiences created by a deficit to the person's perceptual system, and misinterpretation of these experiences due to biased reasoning. We use the Capgras delusion (the claim that one or more of one's close relatives has been replaced by an exact replica or impostor) to illustrate this argument. Our account maintains that people voicing this delusion suffer an impairment that leads to faces being perceived as drained of (...) their normal affective significance, and an additional reasoning bias that leads them to put greater weight on forming beliefs that are observationally adequate rather than beliefs that are a conservative extension of their existing stock. We show how this position can integrate issues involved in the philosophy and psychology of belief, and examine the scope for mutually beneficial interaction. (shrink)

I defend the view that we should not overintellectualize the mind. Nonhuman animals can occupy islands of practical rationality: they can have contextbound reasons for action even though they lack full conceptual abilities. Holism and the possibility of mistake are required for such reasons to be the agent's reasons, but these requirements can be met in the absence of inferential promiscuity. Empirical work with animals is used to illustrate the possibility that reasons for action could be bound to symbolic or (...) social contexts, and connections are made to simulationist accounts of cognitive skills.

b>: there is no “mind-body problem”, or “hard problem of consciousness”; if there is a hard problem of something, it is the problem of reconciling the manifest and scientific images.

When is a belief or judgment justified? One might be forgiven for thinking the search for single answer to this question to be hopeless. The concept of justification is required to fulfil several tasks: to evaluate beliefs epistemically, to fill in the gap between truth and knowledge, to describe the virtuous organization of one’s beliefs, to describe the relationship between evidence and theory (and thus relate to confirmation and probabilification). While some of these may be held to overlap, the prospects (...) for fulfilling all may well seem poor. Furthermore the internalist requires that justification be an introspectible property of beliefs and a fundamental epistemic concept, while the externalist is often happy to ignore the concept altogether or at best regard it as an embarrassing add-on to their epistemology. In the light of this one might reasonably give up on justification altogether or adopt pluralist approach, denying that justification is any single property of beliefs of judgments. (shrink)

I introduce and argue for the importance of a cognitive state that I call alief. An alief is, to a reasonable approximation, an innate or habitual propensity to respond to an apparent stimulus in a particular way. Recognizing the role that alief plays in our cognitive repertoire provides a framework for understanding reactions that are governed by nonconscious or automatic mechanisms, which in turn brings into proper relief the role played by reactions that are subject to conscious regulation and deliberate (...) control.

I aim to show that, contrary to standard deflationary or eliminativist theories of the self, we can argue from the phenomenology of pre-reflective self-awareness for the thesis that subjects of experience are substances. The phenomenological datum of subjectivity points to a specific metaphysical structure of our experience, that is, towards the substance view rather than the bundle or the minimal self view. Drawing on modern philosophical accounts of pre-reflective self-awareness, mineness and (self-) acquaintance, I will argue that a subject is (...) aware of being the one individual who has many experiences and that it is revealed to the subject that it is the bearer of experiences and their unifier. The subject is present in pre-reflective awareness and known as the subject of experiences, and even this minimal self-awareness gives us reason to favour the substance view. Thus, one can demonstrate how the debates on the phenomenology of pre-reflective self-awareness and the metaphysics of selfhood intersect. (shrink)

The concept of personal identity is one of the most sensitive questions in Paul Ricoeur’s oeuvre. In this article we show what makes originality of Ricoeur’s conception of narrative identity by analyzing the way it is presented in Oneself as Another and by pointing out the difference between the ricoeurian concept and the concept of narrative identity, introduced by Alasdair MacIntyre. For this reason we would like to focus on the analysis of configuration and refiguration, studied by Ricoeur in his (...) oeuvre Time and Narrative. We would also include the notion of narrative identity into the conception of hermeneutics and demonstrate that the originality of the ricoerian concept is based on the possibilities offered by the theory of narration explicated in the debates with structuralism and literary theory. This sets the issue of subjectivity, in which the problematic of narrative identity is inscribed. This “philosophy of the first person” makes the key object of the second part of the research. The article shows how the self applies the narrative intrigue to his/her own life by identifying himself with a storyteller or with a character. A reader or a storyteller constructs his/her narrative identity so that the process of self-understanding becomes possible. (shrink)

No es pensando como creamos mundos. Es comprendiendo el mundo como aprendemos a pensar. Cosmovisión es un término que debe significar un conjunto de fundamentos a partir de los cuales emerge una comprensión sistémica del Universo, sus componentes como la vida, el mundo en que vivimos, la naturaleza, el fenómeno humano y sus relaciones. Es, por tanto, un campo de la filosofía analítica alimentado por las ciencias, cuyo objetivo es ese conocimiento agregado y epistemológicamente sostenible sobre todo lo que somos (...) y contenemos, que nos rodea y con lo que nos relacionamos de alguna manera. Es algo tan antiguo como el pensamiento humano y, además de utilizar elementos de la cosmología científica, engloba todo lo que en filosofía y ciencia se refiere al universo y la vida. Una cosmovisión no es un conjunto de ideas, hipótesis y suposiciones, sino un sistema basado en la observación, el análisis, la evidencia y la demostración. Ninguna cosmovisión pretende definir, establecer, proponer, sino solo comprender, analizar e interpretar. Cada uno de nosotros construimos y transportamos nuestra cosmovisión a lo largo de nuestra vida, sin establecer formas, como trasfondo de nuestro pensamiento y comportamiento. Lingüísticamente, el término “cosmovisión” se deriva del alemán, equivalente al concepto de “Weltanschauung” utilizado por varios filósofos. Sin embargo, esta relación lingüística no es aplicable porque va en contra de lo que proponemos como cosmovisión. Esta palabra alemana hace referencia a una visión prelógica o protoexperimental de la realidad, con un contexto intuitivo y alejado de un conocimiento crítico que aún no existía en el momento de su formulación. Sin duda, las cosmovisiones, no tiene sentido en que las entendamos, cobijen y utilicen estos elementos proto-experimentales o prelógicos que incluyen la historia, el inconsciente colectivo y todos los arquetipos que portamos. Sin embargo, en el concepto que aquí aplicamos, la cosmovisión va mucho más allá de este contenido, primero al someterlo constantemente al pensamiento crítico actual y, finalmente, al hacer de la experiencia analítica (y no del pensamiento o la intuición en sí) su verdadero universo. António Lopes expone la amplitud de este contenido: -/- “Las cosmovisiones no son el producto del pensamiento. No nacen del simple deseo de saber. La aprehensión de la realidad es un momento importante en su configuración, sin embargo, es uno solo. Proviene de la conducta vital, de la experiencia de vida, de la estructura de nuestra totalidad psíquica. El apoyo de la vida a la conciencia en el conocimiento de la realidad, en la apreciación de la vida y en la realidad volitiva, es el trabajo lento y arduo que ha hecho la humanidad en el desarrollo de los conceptos de vida. (W. Dilthey, 1992 [1911]: 120)” . En este trabajo buscamos esbozar una cosmovisión a partir de las realidades que ofrece la ciencia en la actualidad. No nos proponemos, en ningún momento, hacer ciencia; o teorizar la filosofía, pero siempre buscaremos ser apoyados por ellos o, al menos, protegidos por ellos de las distorsiones cognitivas que solemos llevar. -/- .

Tessman responds to her three critics’ comments on Burdened Virtues, focusing on their concerns with her stipulation of an “inclusivity requirement,” according to which one cannot be said to flourish without contributing to the flourishing of an inclusive collectivity. Tessman identifies a naturalized approach to ethics—which she distinguishes from the naturalism she implicitly endorsed in Burdened Virtues—that illuminates how a conception of flourishing that meets the inclusivity requirement could carry moral authority.

It is often supposed that the point of equality of opportunity is to create a level playing-field. This is understood in different ways, however. A common proposal is what I call the neutralization view: that people's social circumstances should not differentially affect their life chances in any serious way. I raise problems with this view, before developing an alternative conception of equal opportunity which allows some variations in social circumstances to create differences in life prospects. The meritocratic conception which I (...) defend is grounded in the idea of respect for persons, and provides a less demanding interpretation of fair access to qualifications; it nevertheless places constraints on the behaviour of parents, and has implications for educational provision in schools.

Groundhog Day (Harold Ramis, 1993) and Only Lovers Left Alive (Jim Jarmusch, 2013) are fantasy films that use the device of practical immortality in order to raise important philosophical questions about what constitutes a good life and to explore the nature of romantic love. Groundhog Day provides fairly conventional answers about how to live a good life by focusing on issues of spiritual redemption, selflessness, and developing one’s human potential. In contrast, Lovers provides a dark portrayal of a civilization on (...) the brink of extinction but offers a glimmer of hope for the future. The lifestyle and values of married vampires Adam and Eve represent an alternative vision of the core values needed to sustain a better world: greater reliance on human imagination, maintaining a sense of wonder and curiosity about the world, creating and appreciating works of art and living in harmony with the natural world. Both films also offer a perspective on the importance of romantic love in living a good life. Although these perspectives often diverge from one another, they do overlap in some interesting ways. The style of film criticism used in this paper is inspired by the film philosophy of Stanley Cavell. (shrink)

Utilitarianism focuses on the optimization of personal well being in ways that seems to make the practice of medicine irrelevant to the well being of the practitioners, unless given external incentives such as money or honor. Care based on indirect incentives is considered inferior to care motivated internally. This leads to the paradox of utilitarian care. Following Nozick's conceptual Pleasure Machine it is argued that in addition to the promotion of personal well being, people care about fulfilling their well being (...) in a world which is real, just, good, and beautiful. Complete mechanization of social and personal life in accordance with a strict utilitarian regime is also incompatible with the kind of world people desire, even if it promises more fulfillments in terms of personal well being. This explains the so-called Taurek-Parfit paradox, according to which sometimes ethics seems “to count the numbers” and sometimes not. The very pursuit of utilitarianism does not contribute to any personal life plan. The helping professions make the world a better place for us to live in, even though they do not necessarily bear directly on the well being of any individual other than the recipients of care. This resolves the paradox of utilitarian care. (shrink)

On one predominant conception of virtue, the virtuous agent is, among other things, wholehearted in doing what she believes best. I challenge this condition of wholeheartedness by making explicit the connections between the emotion of boredom and the states of continence and akrasia. An easily bored person is more susceptible to these forms of disharmony because of two familiar characteristics of boredom. First, that we can be – and often are – bored by what it is that we know would (...) be best to do, and second, that occurrent states of boredom tend to give rise to positive interest in performing actions that we know are bad to perform. Moreover, while a person’s susceptibility to boredom can indicate a lack of attentiveness or acuity, or be evidence of a vice such as ingratitude or shallowness, it can in others indicate positive qualities of character, such as perspicacity, liveliness, and certain forms of intelligence. Upon imagining certain bored akratics without the psychological qualities that give rise to their boredom, we will either imagine them without these positive qualities, or with others that – though perhaps psychologically possible – are not clearly better. This yields the result that a person who is continent or even akratic because of her susceptibility to boredom may have a character no less excellent than that of the wholehearted agent. (shrink)

The following four assumptions plausibly describe the ideal rational agent. (1) She knows what her beliefs are. (2) She desires to believe only truths. (3) Whenever she desires that P → Q and knows that P, she desires that Q. (4) She does not both desire that P and desire that ~P, for any P. Although the assumptions are plausible, they have an implausible consequence. They imply that the ideal rational agent does not believe and desire contradictory propositions. She neither (...) desires the world to be any different than she thinks it is, nor thinks it is any different than she desires it to be. The problem of preserving our intuitions about desire, without embracing the implausible conclusion, is what I call “the Wishful Thinking Puzzle.” In this paper, I examine how this puzzle arises, and I argue that it is surprisingly difficult to solve. Even the decision theoretic conception of desire is not immune to the puzzle. One approach, the contrastive conception of desire, does avoid the puzzle without being ad hoc, but it remains too inchoate to win our full confidence. (shrink)

S. Kierkegaard argued that our highest task as humans is to realize an “intensified” or “developed” form of subjectivity—his name for self-responsible agency. A self-responsible agent is not only responsible for her actions. She also bears responsibility for the individual that she is. In this paper, I review Kierkegaard’s account of the role that our capacity for reflective self-evaluation plays in making us responsible for ourselves. It is in the exercise of this capacity that we can go from being subjective (...) in a degraded sense—merely being an idiosyncratic jumble of accidental and arbitrary attitudes and affects—to being a subject in the ideal or eminent sense. The latter requires the exercise of my capacity for reflective self-evaluation, since it involves recognizing, identifying with, and reinforcing those aspects of my overall make-up that allow me to express successfully a coherent way of being in the world. Kierkegaard argues that taking immortality seriously is one way to achieve the right kind of reflective stance on one’s own character or personality. Thus, Kierkegaard argues that immortality as a theoretical posit can contribute to one’s effort to own or assume responsibility for being the person one is. (shrink)

P. F. Strawson suggests an anti-sceptical strategy which consists in offering good reason for ignoring scepticism rather than trying to refute it, and the reason he offers is that beliefs about the external world are indispensable to us. I give an exposition of Strawson's arguments for the indispensability thesis and explain why they are not strong enough. I then propose an argument based on some of Davidson's ideas in his theory of radical interpretation, which I think can establish the indispensability (...) thesis. Finally, I spell out the force of Strawson's anti-sceptical strategy by arguing that we have good reason for ignoring scepticism not only because beliefs about the world are indispensable, but also because it is irrational to have both beliefs about the world and sceptical doubts.

This paper argues that an adequate conception of a good life should recognize, in addition to happiness and morality, a third dimension of meaningfulness. It further proposes that we understand meaningfulness as involving both a subjective and an objective condition, suitably linked. Meaning arises when subjective attraction meets objective attractiveness. In other words one’s life is meaningful insofar as one is gripped or excited by things worthy of one’s love, and one is able to do something positive about it. The (...) paper concludes with some speculations about how this conception of meaningfulness might help to explain the conditions under which social volunteering can be especially rewarding.

Ein Leitmotiv der medizinethischen Auseinandersetzung mit der tiefen Hirnstimulation (THS) ist die Beschäftigung mit Fragen personaler Identität. Da es sich bei personaler Identität auch um ein Problem der theoretischen Philosophie handelt, wird in diesem Aufsatz nicht nur die praktische Frage nach der ethischen Legitimation der THS durch informierte Einwilligung gestellt und ein modifiziertes Legitimationskriterium für wesensändernde THS erarbeitet. Vielmehr wird zunächst versucht, das Problem, um das es in der Debatte um THS und personaler Identität geht, besser zu verstehen.

Some philosophers – notably Bernard Williams, Martha Nussbaum and Ruth Barcan Marcus – argue that agents in moral dilemmas are blameworthy whatever they do. I begin by uncovering the connection these philosophers are presupposing between the agent’s judgement of wrongdoing and her tendency to self-blame. Next, I argue that while dilemmatic choosers cannot help but see themselves as wrongdoers, they both can and should divorce this judgement from an ascription of self-blame. As I argue, dilemmatic choosers are morally sui generis (...) in that their actions result in a diminishment of their personal integrity with no corresponding failure of character. It is this that makes them non-blameworthy wrongdoers. This way of seeing the problem should provide dilemmatic choosers with a novel conception of their own moral psychology, one that allows them to view their actions in a manner that is given neither to moral insensitivity nor to pathological self-accusation.

According to the additive view of sensory imagination, mental imagery often involves two elements. There is an image-like element, which gives the experiences qualitative phenomenal character akin to that of perception. There is also a non-image element, consisting of something like suppositions about the image's object. This accounts for extra- sensory features of imagined objects and situations: for example, it determines whether an image of a grey horse is an image of Desert Orchid, or of some other grey horse. The (...) view promises to give a simple and intuitive explanation of some puzzling features of imagination, and, further, to illuminate imagination 's relation to modal knowledge. I contend that the additive view does not fulfil these two promises. The explanation of how images come to be determinate is redundant: the content constituting the indeterminate mental images on which the view relies is sufficient to deliver determinate images too, so the extra resources offered by the view are not required..

It is commonplace to claim that it is good to believe the truth. In this paper, I reject that claim and argue that the considerations which might seem to support it in fact support a quite distinct though superficially similar claim, namely, that it is bad to believe the false. This claim is typically either ignored completely or lumped together with the previous claim, perhaps on the assumption that the two are equivalent, or at least that they stand or fall (...) together. Such assumptions, I argue, are mistaken. While it is not always good to be right, it is always bad to be wrong. This is an interesting and overlooked asymmetry, which calls for further investigation.

The ‘humanisation’ of education is one of the three leitmotifs in a recent Soviet planning document A Conception of General Education. It is suggested that Western education systems also need to be humanised, although not so radically as the Soviet, by the removal of obstacles to educating pupils as members of a liberal democratic society. A future joint research agenda between East and West should concentrate on improving mutual understanding of this goal, clarifying conceptual obstacles, and reflecting on means of (...) realising it. Specific proposals are put forward under all three headings. (shrink)

It is common to hear talk of the aim of belief and to find philosophers appealing to that aim for numerous explanatory purposes. What belief 's aim explains depends, of course, on what that aim is. Many hold that it is somehow related to truth, but there are various ways in which one might specify belief 's aim using the notion of truth. In this article, by considering whether they can account for belief 's standard of correctness and the epistemic (...) norms governing belief, I argue against certain prominent specifications of belief 's aim given in terms of truth, and advance a neglected alternative.

Every kind of ‘ought’ implies some kind of ‘can’ – but there are many kinds of ‘ought’ and even more kinds of ‘can’. In this essay, I shall focus on a particular kind of ‘ought’ – specifically, on what I shall call the “rational ‘ought’”. On every occasion of use, this kind of ‘ought’ is focused on the situation of a particular agent at a particular time; but this kind of ‘ought’ is concerned, not with how that agent acts at (...) that time, but with what beliefs or intentions the agent has at the time, or with the sort of reasoning by means of which the agent at that time forms or revises those beliefs or intentions.

Biological studies have demonstrated that it is possible to slow the ageing process and extend lifespan in a wide variety of organisms, perhaps including humans. Making use of the findings of these studies, this article examines two problems concerning the effect of life extension on population size and welfare. The first—the problem of overpopulation—is that as a result of life extension too many people will co-exist at the same time, resulting in decreases in average welfare. The second—the problem of underpopulation—is (...) that life extension will result in too few people existing across time, resulting in decreases in total welfare. I argue that overpopulation is highly unlikely to result from technologies that slow ageing. Moreover, I claim that the problem of underpopulation relies on claims about life extension that are false in the case of life extension by slowed ageing. The upshot of these arguments is that the population problems discussed provide scant reason to oppose life extension by slowed ageing. (shrink)

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)

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)

Drawing on Ezekiel Emanuel’s controversial piece ‘Why I hope to die at 75,’ I distinguish two types of concern in ethical debates about extending the human lifespan. The first focusses on the value of living longer from prudential and social perspectives. The second type of concern, which has received less attention, focusses on the value of aiming for longer life. This distinction, which is overlooked in the ethical literature on life extension, is significant because there are features of human psychology (...) and the structure of a life that should give pause when considering how long one should aim to live, but which do not neatly coincide with considerations about how valuable additional life is likely to be. I argue that, while Emanuel’s case for hoping to die at 75 is unconvincing, he nonetheless provides weak pro tanto considerations in favour of taking a moderate life span as a prudential aim around which to base at least some significant life plans.

Peter Singer has argued that there are good utilitarian reasons for rejecting the prospect of superlongevity: developing technology to double (or more) the average human lifespan. I argue against Singer's view on two fronts. First, empirical research on happiness indicates that the later years of life are (on average) the happiest, and there is no reason to suppose that this trend would not continue if superlongevity were realized. Second, it is argued that there are good reasons to suppose that there (...) will be a certain amount of self-selection: the happiest are more likely to adopt superlongevity technology. This means that the adoption of superlongevity technology will have the effect of raising the level of aggregate utility. (shrink)
