This paper develops a form of moral actualism that can explain the procreative asymmetry. Along the way, it defends and explains the attractive asymmetry: the claim that although an impermissible option can be self-conditionally permissible, a permissible option cannot be self-conditionally impermissible.

According to the person-affecting restriction, one distribution of welfare can be better than another only if there is someone for whom it is better. Extant problems for the person-affecting restriction involve variable-population cases, such as the nonidentity problem, which are notoriously controversial and difficult to resolve. This paper develops a fixed-population problem for the person-affecting restriction. The problem reveals that, in the presence of incommensurable welfare levels, the person-affecting restriction is incompatible with minimal requirements of impartial beneficence even in fixed-population (...) contexts.

According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist. My aim in this paper is to explain how asymmetric comparativism could possibly be true. My account of asymmetric comparativism begins with a different asymmetry, regarding the (dis)value of early death. I offer an account of this early death asymmetry, appealing to the (...) idea of conditional goods, and generalize it to explain how asymmetric comparativism could possibly be true. I also address the objection that asymmetric comparativism has unacceptably antinatalist implications. (shrink)

Most believe that it is worse for a person to die than to continue to exist with a good life. At the same time, many believe that it is not worse for a merely possible person never to exist than to exist with a good life. I argue that if the underlying properties that make us the sort of thing we essentially are can come in small degrees, then to maintain this commonly-held pair of beliefs we will have to embrace (...) an implausible sort of evaluative hypersensitivity to slight nonevaluative differences. Avoidance of such hypersensitivity pressures us to accept that it can be worse for merely possible people never to exist. If this conclusion is correct, then the standard basis for giving no or less priority to merely possible persons would disappear (i.e., that things cannot be better or worse for them). Though defenders of Person-Affecting Views and their opponents may still disagree in theory, they could arrive at the same answers to many monumentally important practical questions. (shrink)

One of the most difficult issues to sort out morally is our obligation to future generations. Most individuals feel that they do indeed have some kind of obligation, but face difficulty in explaining the exact nature of the obligation. For one, it seems impossible to know the wants and desires of future generations, and furthermore the existence of the persons we are obligated to is entirely dependent upon the choices that we in fact make. In essence, we could shape future (...) generations so that they desire exactly what we provide for them. It seems that no matter what principle we adopt that is based upon these potential individuals we are led to absurd conclusions. Gregory Kavka calls this moral grappling the Paradox of Future Individuals. I believe that the ethical concerns surrounding genetic engineering should be seen as a specific instantiation of this Paradox and that by examining both we may be able to come up with some sort of working solution. Derek Parfit pleads ignorance as to a solution to this Paradox after an extensive exegesis on the issue, but as we may not be that far from shopping a genetic supermarket to determine the characteristics of our children I don’t believe we can settle for that conclusion. We will begin by examining the Paradox and suggested solutions to the Paradox. Next I will address how the Paradox relates directly to genetic engineering and discuss how rights-based arguments aimed against genetic engineering fail because of the nature of identity. Then I will consider how David Heyd’s Genero-centric principle applies to genetic engineering specifically and how a modified version of that principle may guide us out of the Paradox of Future Individuals in general. This solution may not be acceptable to utilitarian sensibilities, but it is because the numbers don’t add up that we may need to appeal to a different principle entirely. (shrink)

In Reasons and Persons, Parfit (1984) posed a challenge: provide a satisfying normative account that solves the Non-Identity Problem, avoids the Repugnant and Absurd Conclusions, and solves the Mere-Addition Paradox. In response, some have suggested that we look toward person-affecting views of morality for a solution. But the person-affecting views that have been offered so far have been unable to satisfy Parfit's four requirements, and these views have been subject to a number of independent complaints. This paper describes a person-affecting (...) account which meets Parfit's challenge. The account satisfies Parfit's four requirements, and avoids many of the criticisms that have been raised against person-affecting views. (shrink)

This is a review of contemporary philosophical discussions of population policies. The focus is on normative justification, and the main question is whether population policies can be ethically justified. Although few analytical philosophers have directly addressed this question – it has been discussed more in other academic fields – many arguments and considerations can be placed in the analytical philosophical discourse. This article offers a comprehensive review and analysis of ethically relevant aspects of population policies evaluated on the basis of (...) the main ethical theories. This analysis is preceded by a brief historical contextualisation of when and how population policies became ethically contentious and how this relates to philosophical debates in environmental ethics, population ethics and political philosophy. The article also includes a conceptual analysis of population policies in which the empirical intricacies around individual fertility decisions are sorted out and the different ways in which they can be affected are categorised in a taxonomy which highlight the most relevant ethical aspects of population policies. The ethical analysis shows that while population policies can be justified on the basis of most ethical theories, it all depends on what prior assumptions are made about what is at stake. (shrink)

Effective altruism encourages people to donate their money to the most effective, efficient charities. Some effective altruists believe that taking a longtermist priority—benefitting far-off future, enormous generations—is one of the best ways to use our resources. This paper explains how the longtermist argument as laid out by William MacAskill in his book What We Owe the Future, is unconvincing. MacAskill argues that we should ensure that the future is very well-populated on the assumption that it will be on balance good (...) over bad. This reasoning, however, fails to account for additional moral considerations that most people would endorse. The present critique of pronatalist longtermism advances a critical benefit theory compatible with putting our energy into preventing and alleviating serious harms to actual future generations without intensive pronatalism.

Der Beitrag setzt sich kritisch mit dem Prinzip des prokreativen Wohltuns von Julian Savulescu und seinen Implikationen für den Umgang mit der Präimplantationsdiagnostik auseinander. PB fordert angehende Eltern dazu auf, aus mehreren möglichen zukünftigen Kindern dasjenige auszuwählen, dessen Leben voraussichtlich am besten verlaufen wird. Paare mit Kinderwunsch sind danach zumindest unter bestimmten Umständen moralisch verpflichtet, eine PID in Anspruch zu nehmen, um die Weitergabe genetisch bedingter Krankheiten zu verhindern. Die Auswahl von Embryonen im Rahmen einer PID kann jedoch nur dann (...) mit dem Wohlergehen des zukünftigen Kindes begründet werden, wenn man die entsprechende Wohltunspflicht mit Savulescu und Kahane als „unpersönliche“ moralische Pflicht versteht.

Gegen Savulescu und Kahane argumentiere ich dafür, reproduktive Verantwortung als einen integralen Aspekt elterlicher Verantwortung und damit als personenbezogene Verantwortung zu deuten, und verteidige diese Konzeption reproduktiver Verantwortung gegen Einwände, die sich aus einem von Savulescu und Kahane konstruierten hypothetischen Szenario – dem Röteln-Beispiel – ergeben.

In engaging with the repugnant conclusion many contemporary philosophers, economists and social scientists make claims about what a minimally good life is like. For example, some claim that such a life is quite good by contemporary standards, and use this to defend classical utilitarianism, whereas others claim that it is not, and use this to uphold the challenge that the repugnant conclusion poses to classical utilitarianism. I argue that many of these claims—by both sides—are not well-founded. We have no sufficiently (...) clear sense of what a minimally good life is like. It is a result of this that the repugnant conclusion doesn’t license us in drawing any interesting conclusions. (shrink)

In this essay I describe how contractarianism might approach interspecies welfare conflicts. I start by discussing a contractarian account of the moral status of nonhuman animals. I argue that contractors can agree to norms that would acknowledge the “moral standing” of some animals. I then discuss how the norms emerging from contractarian agreement might constrain any comparison of welfare between humans and animals. Contractarian agreement is likely to express some partiality to humans in a way that discounts the welfare of (...) some or all animals. While the norms emerging from the contract might be silent or inconsistent in some tragic or catastrophic cases, in most ordinary conflicts of welfare, contractors will agree to norms that produce some determinate resolution. What the agreement says can evolve depending upon how the contractors or the circumstances change. I close with some remarks on contractarian indeterminacy. (shrink)

While morality prohibits us from creating miserable children, it does not require us to create happy children. I offer an actualist explanation of this apparent asymmetry. Assume that for every possible world W, there is a distinct set of permissibility facts determined by the welfare of those who exist in W. Moral actualism says that actual-world permissibility facts should determine one's choice between worlds. But if one doesn't know which world is actual, one must aim for subjective rightness and maximize (...) expected actual-world permissibility. So, because one should expect actual people to be worse off than they could have been if one creates a miserable child, creating a miserable child is subjectively impermissible. And because one should expect actual people to be at least as well off as they could have been if one fails to create a happy child, failing to create a happy child is subjectively permissible.

Advances in technology have made it possible for us to take actions that affect the numbers and identities of humans and other animals that will live in the future. Effective and inexpensive birth control, child allowances, genetic screening, safe abortion, in vitro fertilization, the education of young women, sterilization programs, environmental degradation and war all have these effects. Although it is true that a good deal of effort has been devoted to the practical side of population policy, moral theory has (...) not dealt adequately with the new possibilities. The dilemma faced by moral theory is that traditional theories cannot answer moral questions involving the creation of people. Two related problems arise. The first concerns numbers: how many people should there be? The second asks what sort of people should live and what their levels of well-being should be. Conventional social-contract theories, including the work of Rawls (1971), are restricted to situations with a fixed number of individuals. Sumner (1978) attempts to extend a Rawlsian veil-of-ignorance approach to possible people but is aware of the difficulties involved. The main problem is that possible people must be thought to benefit when they move from non-existence to existence, a view that we reject (see Section 1, Heyd, 1992, Chapter 1; McMahan, 1996a; Parfit, 1984, Appendix G). Rights-based and duty-based theories suffer from a similar problem; there must be a person who has the right or a person to whom the duty is owed (see McMahan, 1981). (shrink)

The mere means principle says it is impermissible to treat someone as merely a means to someone else’s ends. I specify this principle with two conditions: a victim is used as merely a means if the victim does not want the treatment by the agent and the agent wants the presence of the victim’s body. This principle is a specification of the doctrine of double effect which is compatible with moral intuitions and with a restricted kind of libertarianism. An extension (...) of this mere means principle, where not only using but also considering someone as merely a means is immoral, can explain and unify other deontological principles: doing versus allowing, partiality in imperfect duties of beneficence, and the asymmetry of procreational duties. A loop trolley dilemma is often presented as a counterexample of the mere means principle, but I argue that this dilemma generates a moral illusion, comparable to perceptual illusions. (shrink)

It is often said that while we have a strong reason not to create someone who will be badly off, we have no strong reason for creating someone who will be well off. In this paper I argue that this asymmetry is incompatible with a plausible principle of independence of irrelevant alternatives, and that a more general asymmetry between harming and benefiting is difficult to defend. I then argue that, contrary to what many have claimed, it is possible to harm (...) or benefit someone by bringing her into existence. (shrink)

Although many people believe that more people would be better, arguments intended to show this are unconvincing. I consider one of Parfit's arguments for a related conclusion, that even when both are worth living, we ought to prefer the better of two lives. Were this argument successful, or so I claim, then it would follow that more people would be better. But there aren't reasons for preferring the better of two lives. Nor is an attempted rejoinder effective. We can agree (...) that there aren't reasons for preferring the better of two lives, and yet still maintain there are reasons for improving lives. (shrink)

In slogan form, the thesis of this dissertation is that shaping the far future is overwhelmingly important. More precisely, I argue that: Main Thesis: From a global perspective, what matters most is that we do what is best for the general trajectory along which our descendants develop over the coming millions, billions, and trillions of years. The first chapter introduces some key concepts, clarifies the main thesis, and outlines what follows in later chapters. Some of the key concepts include: existential (...) risk, the world's development trajectory, proximate benefits and ripple effects, speeding up development, trajectory changes, and the distinction between broad and targeted attempts to shape the far future. The second chapter is a defense of some methodological assumptions for developing normative theories which makes my thesis more plausible. In the third chapter, I introduce and begin to defend some key empirical and normative assumptions which, if true, strongly support my main thesis. In the fourth and fifth chapters, I argue against two of the strongest objections to my arguments. These objections come from population ethics, and are based on Person-Affecting Views and views according to which additional lives have diminishing marginal value. I argue that these views face extreme difficulties and cannot plausibly be used to rebut my arguments. In the sixth and seventh chapters, I discuss a decision-theoretic paradox which is relevant to my arguments. The simplest plausible theoretical assumptions which support my main thesis imply a view I call fanaticism, according to which any non-zero probability of an infinitely good outcome, no matter how small, is better than any probability of a finitely good outcome. I argue that denying fanaticism is inconsistent with other normative principles that seem very obvious, so that we are faced with a paradox. I have no solution to the paradox; I instead argue that we should continue to use our inconsistent principles, but we should use them tastefully. We should do this because, currently, we know of no consistent set of principles which does better. (shrink)

The idea that the phenomenon of morality and, consequently, our ability to distinguish between vice and virtue can be explained by sympathy has been challenged as a highly controversial hypothesis, since sympathy appears to be easily influenced by proximity and selective, and would therefore seem incompatible with the possibility of taking an impartial, objective point of view. We intend to show that even a sentimentalist moral perspective such as the ‘Humean’ one, which places empathy (or ‘sympathy’, as Hume calls it) (...) at the core of morality, is capable of accounting for and justifying moral responsibility to future generations. Moreover, if we consider things from a Humean perspective, it is immoral not only to harm future generations, but also not to care at all about the extinction of the human species. For in the former case, we perform actions that cause misery, pain and suffering, whilst in the latter, we are not at all concerned about the welfare (i.e., happiness) of possible people who may, in the near future, come into the world and have a life worth or very much worth living. That is, in both cases, we show no ability to empathize with the possible people who will or may be born tomorrow. (shrink)

This article presents a revised version of negative utilitarianism. Previous versions have relied on a hedonistic theory of value and stated that suffering should be minimized. The traditional rebuttal is that the doctrine in this form morally requires us to end all sentient life. To avoid this, a need-based theory of value is introduced. The frustration of the needs not to suffer and not to have one’s autonomy dwarfed should, prima facie, be decreased. When decreasing the need frustration of some (...) would increase the need frustration of others, the case is deferred and a fuller ethical analysis is conducted. The author’s perceptions on murder, extinction, the right to die, antinatalism, veganism, and abortion are used to reach a reflective equilibrium. The new theory is then applied to consumerism, material growth, and power relations. The main finding is that the burden of proof should be on those who promote the status quo. (shrink)

Antinatalism is an emerging philosophy and practice that challenges pronatalism, the prevailing philosophy and practice in reproductive matters. We explore justifications of antinatalism—the arguments from the quality of life, the risk of an intolerable life, the lack of consent, and the asymmetry of good and bad—and argue that none of them supports a concrete, understandable, and convincing moral case for not having children. We identify concentration on possible future individuals who may or may not come to be as the main (...) culprit for the failure and suggest that the focus should be shifted to people who already exist. Pronatalism’s hegemonic status in contemporary societies imposes upon us a lifestyle that we have not chosen yet find almost impossible to abandon. We explicate the nature of this imposition and consider the implications of its exposure to different stakeholders with varying stands on the practice of antinatalism. Imposition as a term has figured in reproductive debates before, but the argument from postnatal, mental, and cultural imposition we launch is new. It is the hitherto overlooked and underdeveloped justification of antinatalism that should be solid and comprehensible enough to be used even by activists in support of their work. (shrink)

Suppose that A and B are two kinds of goods such that more of each is better than less. A is strongly superior to B if any amount of A is better than any amount of B. It is weakly superior to B if some amount of A is better than any amount of B. There are many examples of these relations in the literature, sometimes under the labels “higher goods” and “discontinuity.” The chapter gives a precise and generalized statement (...) of Strong and Weak Superiority and discusses different ways in which these relations can be relevant to the aggregation of welfare. It also proves a number of general results. One of the results gives rise to a dilemma: It can be used as an argument against the existence of value superiority or, alternatively, as an argument against the view that superiority entails a radical difference in value.

Recently, in his Rolf Schock Prize Lecture, Derek Parfit has suggested a novel way of avoiding the Repugnant Conclusion by introducing what he calls “imprecision” in value comparisons. He suggests that in a range of important cases, populations of different sizes are only imprecisely comparable.

In this article, I (...) try to clarify Parfit's proposal and evaluate whether it will help us with the paradoxes in population ethics. (shrink)

On an act utilitarian view it is morally permissible if not obligatory to choose to perform an action which contributes as much as any other action to the total happiness of all those capable of enjoying happiness. As the view has just been stated, however, there is some question of how we are to understand the phrase “all those capable of enjoying happiness”. For even leaving aside the possibility that animals or spirits might be included, there is still the matter (...) of the size of the population of humans “capable of enjoying happiness”. Furthermore, among our ethical decisions themselves are decisions which would cause a decrease or increase in population and which in perhaps even more specific ways determine the applicability of this phrase “all those capable of enjoying happiness”. According to the socalled classical or total utilitarian principle, the phrase in question is understood as describing some population whose existence will enable one to maximize the net amount of happiness. For on the classical principle what one is obligated to do is simply to maximize net happiness. (shrink)

A common intuition is that there is a moral difference between ‘making people happy’ and ‘making happy people.’ This intuition, often referred to as ‘the Asymmetry,’ has, however, been criticized on the grounds that it is incoherent. Why is there, for instance, not a corresponding difference between ‘making people unhappy’ and ‘making unhappy people’? I argue that the intuition faces several difficulties but that these can be met by introducing a certain kind of reason that is favouring but non-requiring. It (...) is argued that there are structural similarities between the asymmetry and moral options and that the asymmetry can be defended as an instance of a moral option. (shrink)

Is there a pro tanto moral reason to create a life merely because it would be good for the person living it? Proponents of the procreation asymmetry claim there is not. Defending this controversial no reason claim, some have suggested that it is well in line with other phenomena in the moral realm: there is no reason to give a promise merely because one would keep it, and there is no reason to procreate merely to increase the extent of justice (...) in the world. Allegedly, some analogs extend so far as to support a unified theory of the no reason claim and the nonidentity thesis, that is, the view that of two persons leading lives of positive wellbeing, there is a reason to create the person with higher wellbeing. I dismantle the proposed analogs and show that they fail to meet various desiderata. Moreover, I refute Johann Frick's argument that the no reason claim follows from the assumption that reasons of beneficence are reasons to act for the sake of people. By criticizing attractive defenses for the no reason claim, I weaken its plausibility. (shrink)

This paper offers a unified explanation for the procreation asymmetry and the non-identity thesis – two of the most intractable puzzles in population ethics. According to the procreation asymmetry, there are moral reasons not to create lives that are not worth living but no moral reasons to create lives that are worth living. I explain the procreation asymmetry by arguing that there are moral reasons to prevent the bad, but no moral reasons to promote the good. Various explanations for the (...) procreation asymmetry have failed to explain the non-identity thesis: if one could create a person with a good life or a different person with a better life, one has a moral reason to create the better life. I argue that reflections on the misfortune of unfulfilled potential allow us to circumvent the non-identity problem. (shrink)

The multiverse theodicy proposes to reconcile the existence of God and evil by supposing that God created all and only the creation-worthy universes and that some universes like ours are, despite their evils, creation-worthy. Drawing on work in population ethics, this paper develops a novel challenge to the multiverse theodicy. Roughly, the challenge contends that the axiological underpinnings of the multiverse theodicy harbor a ‘mere addition paradox’: the assumption that creating creation-worthy universes would always make the world better turns out (...) to have morally repugnant consequences akin to those of the assumption that adding worthwhile lives to a population would always make the overall welfare of the population better. Further, the challenge leverages this difficulty into an argument against God’s having created all and only the creation-worthy universes, and hence against the multiverse theodicy. Responses to this challenge are considered but found wanting, largely because of commitments of the multiverse theodicy that have no analogs in population ethics. (shrink)

Is it fair to leave the next generation a public debt? Is it defensible to impose legal rules on them through constitutional constraints? From combating climate change to ensuring proper funding for future pensions, concerns about ethics between generations are everywhere.

These include libertarian, Rawlsian, sufficientarian, contractarian, communitarian, Marxian and reciprocity-based approaches. In Part Two, the authors look (...) more specifically at issues relevant to each of these theories, such as motivation to act fairly towards future generations, the population dimension, the formation of preferences through education and how they impact on our intergenerational obligations, and whether it is fair to rely on constitutional devices.

Appeals to the moral value of nature and naturalness are commonly used in debates about technology and the environment and to inform our approach to the ethics of technology and the environment more generally. In this paper, I will argue, firstly, that arguments from nature, as they are used in debates about new technologies and about the environment, are misinterpreted when they are understood as attempting to put forward categorical objections to certain human activities and, consequently, their real significance is (...) often overlooked. Secondly, arguments from nature, particularly as they are used in the context of debates over the use of new technologies, can be understood as appealing to human nature as a way to determine human limitations. Thirdly, arguments from nature can inform our discussion of what it is to be a human being or a person, and this kind of discussion can, in turn, inform our ethical deliberations in such areas of bioethics as euthanasia, abortion, etc. Finally, I conclude that a proper understanding of these arguments can help in establishing which virtues and which vices relate to our relationship with the non-human world—that is, which character dispositions are relevant to an environmental virtue ethics, with human nature as its foundation. A proper understanding of the argument from nature provides the basis for a ‘virtuously anthropocentric’ environmental ethics. (shrink)

What moral reasons, if any, do we have to ensure the long-term survival of humanity? This article contrastively explores two answers to this question: according to the first, we should ensure the survival of humanity because we have reason to maximize the number of happy lives that are ever lived, all else equal. According to the second, seeking to sustain humanity into the future is the appropriate response to the final value of humanity itself. Along the way, the article discusses (...) various issues in population axiology, particularly the so-called Intuition of Neutrality and John Broome’s ‘greediness objection’ to this intuition.

The question I address in this paper is whether and under what conditions it is morally right to bring a person into existence. I defend the commonsensical thesis that, other things being equal, it is morally wrong to create a person who will be below some threshold of quality of life, even if the life of this potential person, once created, will nevertheless be worth living. However commonsensical this view might seem, it has shown to be problematic because of the (...) so-called 'Non-Identity Problem'. Both utilitarian and rights-based approaches have been unable to provide a solution to this problem. I rest my thesis on two premises: that causing a disability or impairment in a future person is prima facie wrong, so long as we can avoid causing such a disability to that very person; and that reproduction, under normal conditions, is prima facie morally indifferent. From these two premises, I conclude that it is prima facie wrong to bring into existence a person with a non-trivial disability or impairment (which might be, nonetheless, compatible with a worthwhile life), even if the only available alternative is to remain childless.

The concept of antinatalism is now becoming popular on the Internet. Many online newspaper articles deal with this topic, and numerous academic papers on antinatalism have been published over the past ten years in the fields of philosophy and ethics. The word “antinatalism” was first used in the current meaning in 2006, when the two books that justify the universal negation of procreation were published: one by David Benatar and the other by Théophile de Giraud. However, we can find various (...) prototypes of antinatalistic thoughts in ancient Greece, ancient India, and modern Europe. You might recall the name Schopenhauer. In this paper, I briefly summarize the history of antinatalistic thoughts and propose a set of categories on antinatalism and related thoughts. (shrink)

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)

A possible person’s conditional expected well-being is what the quality of their prospects would be if they were to come into existence. This paper examines the role that this form of expected well-being should play in distributing benefits among prospective people and in deciding who to bring into existence. It argues for a novel egalitarian view on which it is important to ensure equality in people’s life prospects, not merely between actual individuals, but also between all individuals who, given our (...) choices, have a chance of coming into existence. The paper argues that such egalitarianism for prospective people springs from equal concern for each person and has plausible implications. It further shows that it has a rationale in respect for both the unity of the individual and the separateness of persons. Finally, it defends this view against a key objection and shows it is superior to a rival view. (shrink)

It is one thing to say that the suffering of non-human animals ought to be considered equally with the like suffering of humans; quite another to decide how the wrongness of killing non-human animals compares with the wrongness of killing human beings. It is argued that while species makes no difference to the wrongness of killing, the possession of certain capacities, in particular the capacity to see oneself as a distinct entity with a future, does. It is claimed, however, that (...) this is not the only factor to be taken into account: pleasant or happy life is in itself good. The application of these conclusions to killing animals for food is then considered, with some passing reflections on infanticide. (shrink)

Bill Anglin has an ingenious argument in support of the classical utilitarian view that there is an obligation to create extra people if the people thus created will, on balance, be happy, and creating them will not reduce the happiness of others by a comparable amount. Ingenious as it is, I believe the argument is fallacious.Anglin's argument rests on a case in which a woman has a choice between having a child whose expected level of happiness is zero or undergoing (...) a minor operation, involving only a tiny amount of unhappiness for herself, and then having a child certain to be very happy. Anglin assumes that the woman ought to have the operation, and I do not think we should quarrel with this assumption.The remainder of the argument is swiftly stated. First Anglin claims that for a utilitarian it must be morally indifferent whether one brings into existence an extra person who would experience neither happiness nor unhappiness at any time in his life, or does not bring anyone into existence.

Argues that inadvisable procreative acts should often be affirmed in retrospect. This shift is not explained by attachment or love but by the moral impact of existence.

This article argues for the elimination of the concept of life worth living from philosophical vocabulary on three complementary grounds. First, the basic components of this concept suffer from multiple ambiguities, which hamper attempts to ground informative evaluative and classificatory judgments about the worth of life. Second, the criteria proposed to track the extension of the concept of life worth living rest on unsupported axiological assumptions and fail to identify precise and plausible referents for this concept. And third, the concept (...) of life worth living is not shown to serve any major evaluative or classificatory purpose besides those served by already available axiological concepts. By eliminating the concept of life worth living, philosophers will free themselves of the task of addressing ill-posed axiological questions and ground reflection about the worth of life on more rigorous conceptual foundations.
