Policy-makers must sometimes choose between an alternative which has somewhat lower expected value for each person, but which will substantially improve the outcomes of the worst off, or an alternative which has somewhat higher expected value for each person, but which will leave those who end up worst off substantially less well off. The popular ex ante Pareto principle requires the choice of the alternative with higher expected utility for each. We argue that ex ante Pareto ought to be rejected (...) because it conflicts with the requirement that, when possible, one ought to decide as one would with full information. We apply our argument in an analysis of US policy on screening for breast cancer. -/- . (shrink) | |
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. | |
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 paper argues that non-identity actions are wrong because they _cause_ harm to people. While non-identity actions also typically benefit people, failure to act would similarly benefit someone, so considerations of benefit are ineligible to justify the harm. However, in some non-identity cases, failure to act would not benefit anyone: cases where one is choosing whether to procreate at all. These are the _hard_ non-identity cases. Not all "different-number" cases are hard. In some cases, we don't know whether acting would (...) result in more or fewer people; this paper argues that this _epistemic_ factor makes acting in these cases wrong. (shrink) | |
There is a significant debate over the moral status of human embryos. This debate has important implications for practices like abortion and IVF. Some argue that embryos have the same moral status as infants, children, and adults. However, critics claim that the frequency of pregnancy loss/miscarriage/spontaneous abortion shows a moral inconsistency in this view. One line of criticism is that those who know the facts about pregnancy loss and nevertheless attempt to conceive children are willing to sacrifice embryos lost for (...) the healthy children they ultimately have. I respond to this criticism and argue that on the most plausible accounts of well-being, these embryos are not made worse off and thus not “sacrifices.” I then make some more general remarks about what people’s typical views about pregnancy loss show about their views toward the moral status of embryos.

Given that a person's death is bad for her,whenis it bad? I defendsubsequentism, the view that things that are bad in the relevant way are bad after they occur. Some have objected to this view on the grounds that it requires us to compare the amount of well-being the victim would have enjoyed, had she not died, with the amount she receives while dead; however, we cannot assign any level of well-being, not even zero, to a dead person. In the (...) population ethics literature, many philosophers have argued along similar lines that bringing someone into existence can neither harm nor benefit her. Working within the comparative framework (on which harms make us worse off), I respond by proposing a good sense in which we can say that dead people, and actual people at alternatives in which they do not exist, have a well-being level of zero.

The Asymmetry consists of two claims. (A) That a possible person's life would be abjectly miserable –less than worth living – counts against bringing that person into existence. But (B) that a distinct possible person's life would be worth living or even well worth living does not count in favour of bringing that person into existence. In recent years, the view that the two halves of the Asymmetry are jointly untenable has become increasingly entrenched. If we say all persons matter (...) morally whether they exist or not and on that basis try to explain the first half of the Asymmetry, we lose the second half of the Asymmetry. If we say that some persons do not matter morally and some do and on that basis try to explain the second half of the Asymmetry, we lose the first half of the Asymmetry – or else find ourselves with a principle that is either inconsistent or otherwise deeply troubled in some way that has nothing to do with the content of the Asymmetry itself. In this article, I propose an alternative approach to the Asymmetry which I will call Variabilism. By understanding each and every person, whether existing or not, to matter morally but variably– such that the moral significance of any loss incurred by any person is considered to depend, not on who incurs that loss and whether that person matters morally, but rather on where that loss is incurred in relation to the person who incurs it – we can both nicely ground the two halves of the Asymmetry and avoid the conceptual difficulties that have plagued competing approaches.

According to the person-affecting view, the ethics of welfare should be cashed out in terms of how the individuals are affected. While the narrow version fails to solve the non-identity problem, the wide version is subject to the repugnant conclusion. A middle view promises to do better – the Interpersonal Comparative View of Welfare (ICV). It modifies the narrow view by abstracting away from individuals’ identities to account for interpersonal gains and losses. The paper assesses ICV’s merits and flaws. ICV (...) solves the non-identity problem, avoids the repugnant conclusion, and seems to accommodate the person-affecting intuition. But it cuts too many things along the way: ICV obstructs the advantage of the wide view to account for all future individuals’ welfare, abandons the intuitions that underlie the narrow view, and even violates its own presuppositions by turning out to be merely pseudo person-affecting.

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) | |
According to the Asymmetry, it is wrong to bring a miserable child into existence but permissible not to bring a happy child into existence. When it comes to procreation, we don’t have complete procreative liberty. But we do have some discretion. The Asymmetry seems highly intuitive. But a plausible account of the Asymmetry has been surprisingly difficult to provide, and it may well be that most moral philosophers – or at least most consequentialists – think that all reasonable efforts to (...) provide such an account have by now been exhausted. In this paper, I argue that, despite the difficulties, the Asymmetry is too important to be set aside. I also note a handful of accounts of the Asymmetry that have been proposed and why they fail. It seems, for example, that it will not do to say that some people matter morally and others don’t, or that a person matters morally in some worlds but not others. My own conclusion is that, while we are bound to say all people matter morally – you, me and the merely possible – we are not bound to say that all their losses– or all ours– matter morally. We can instead distinguish between morally significant and insignificant losses, with the distinction between the two being a matter of where the loss is incurred in relation to the person who incurs it. This way of looking at things – which I call Variabilism– provides the basis for a plausible account of the Asymmetry. The availability of such an account suggests, I think, that our prospects for rescuing the Asymmetry are bright. (shrink) | |
Many have offered accounts of the procreative asymmetry, the claim that one has no moral reason to create a life just because it would be happy, but one has moral reason not to create a life just because it would be miserable. I suggest a new approach. Instead of looking at the procreative asymmetry on its own, we can situate it within a broader landscape of asymmetries. Specifically, there are two other analogous asymmetries in the prudential and epistemic domains. The (...) prudential asymmetry says that one has no prudential reason to acquire a desire just because it would be satisfied, but one has prudential reason not to acquire a desire just because it would be frustrated. The epistemic asymmetry says that one has no epistemic reason to acquire a belief just because it is true, but one has epistemic reason not to acquire a belief just because it is false. The existence of these analogous asymmetries in these normative domains suggests the possibility of a unified account of all three asymmetries as instances of a more fundamental asymmetry of value-based reasons. This paper develops a working model of what such a unified account might look like. Such an account can give us a unified explanation of a variety of phenomena, reinforce the plausibility of each of these asymmetries, and give us a novel picture of how value gives us reasons that might extend beyond these three applications.

In this article I discuss the question of whether a person’s existence can be better (or worse) for him than his non-existence. Recently, Nils Holtug and Melinda A. Roberts have defended an affirmative answer. These defenses, I shall argue, do not succeed. In different ways, Holtug and Roberts have got the metaphysics and axiology wrong. However, I also argue that a person’s existence can after all be better (or worse) for him than his non-existence, though for reasons other than those (...) provided by Holtug and Roberts.

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) | |
When our choice affects some other person and the outcome is unknown, it has been argued that we should defer to their risk attitude, if known, or else default to use of a risk‐avoidant risk function. This, in turn, has been claimed to require the use of a risk‐avoidant risk function when making decisions that primarily affect future people, and to decrease the desirability of efforts to prevent human extinction, owing to the significant risks associated with continued human survival. I (...) raise objections to the claim that respect for others' risk attitudes requires risk‐avoidance when choosing for future generations. In particular, I argue that there is no known principle of interpersonal aggregation that yields acceptable results in variable population contexts and is consistent with a plausible ideal of respect for others' risk attitudes in fixed population cases.

The valence of a life – that is, whether it is good, bad or neutral – is an important consideration in population ethics. This paper examines various definitions of valence. The main focus is ‘temporal’ definitions, which define valence in terms of the ‘shape’ of a life’s value over time. The paper argues that temporal definitions are viable only with a restricted domain, and therefore are incompatible with certain substantive theories of well-being. It also briefly considers some popular non-temporal definitions, (...) and raises some problems for these. (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) | |
Jan Narveson has articulated a deeply held, widely shared intuition regarding what moral law has to say about bringing additional people into existence: while we are “in favour of making people happy,” we are “neutral about making happy people.” Various formulations of the Narvesonian intuition (closely related to the person-affecting intuition or restriction) have been widely criticized. This present paper outlines an off-the-beaten-path alternate construction of the intuition—the existence condition—and argues that that particular construction has the resources to avoid some (...) of those criticisms. But still other considerably more widely recognized alternate constructions have been offered as well. Thus John Broome outlines what he calls the neutrality intuition. While Broome finds the underlying intuition “strongly attractive,” he nonetheless argues that the neutrality intuition itself leads us quickly into inconsistency. Wlodek Rabinowicz disagrees. On his view, Broome’s inconsistency argument shows, not that the neutrality intuition is false, but rather that it doesn’t follow, from the fact that the outcome, or possible future or world, that includes the additional person is neither better nor worse than the (otherwise similar) world that excludes that person, that the one world is exactly as good as the other. The better view, according to Rabinowicz, is that, on occasion, and specifically when the coming into existence of additional people is at stake, the one world is incommensurate with the other. What is called the principle of trichotomy is, in other words, false. Difficulties arise, however, when we try to reject that seemingly compelling conceptual principle. This present paper concludes with the argument that the availability of the existence condition—which, together with certain other uncontroversial moral principles and a handful of conceptual principles, forms the existential approach—shows that we can maintain the most intuitive parts of neutrality intuition while avoiding both Broome’s inconsistency worry and Rabinowicz’s commitment to incommensurability. Incommensurability may be correct on other grounds—but not, this present paper argues, on the grounds provided by Broome’s inconsistency argument. (shrink) No categories | |
If a potential person would have a good life if he were to come into existence, can we regard his coming into existence as better for him than his never coming into existence? And can we regard the situation in which he never comes into existence as worse for him? In this paper, we argue that both questions should be answered affirmatively. | |

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) | |
Rule-Consequentialism faces “the problem of partial acceptance”: How should the ideal code be selected given the possibility that its rules may not be universally accepted? A new contender, “Calculated Rates” Rule-Consequentialism claims to solve this problem. However, I argue that Calculated Rates merely relocates the partial acceptance question. Nevertheless, there is a significant lesson from this failure of Calculated Rates. Rule-Consequentialism’s problem of partial acceptance is more helpfully understood as an instance of the broader problem of selecting the ideal code (...) given various assumptions—assumptions about who will accept and comply with the rules, but also about how the rules will be taught and enforced, and how similar the future will be. Previous rich discussions about partial acceptance provide a taxonomy and groundwork for formulating the best version of Rule-Consequentialism. (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) | |

This article articulates and defends a dissolution of the so-called repugnant conclusion, which focuses on the notion of life worth living figuring both in Parfit's formulation of the repugnant conclusion and in most responses to such a conclusion. The proposed dissolution demonstrates that the notion of life worth living is plagued by multiple ambiguities and that these ambiguities, in turn, hamper meaningful debate about both the issue of whether the repugnant conclusion can be avoided and the issue of whether the (...) repugnant conclusion is actually repugnant. This result does not exclude that some modified versions of the repugnant conclusion may yield valuable insights about the value of populations and the tenability of different axiological/ethical theories. Still, if the proposed dissolution is correct, then the repugnant conclusion rests on an ill-defined notion and we lack the information required to assess the merits of the repugnant conclusion.

What difference does it make to matters of value, for a desire satisfactionist, if a given desire is *absent*, rather than *present*? I argue that it is most plausible to hold that the state in which a given desire is satisfied is, other things being equal, incommensurate with the state in which that desire does not exist at all. In addition to illustrating the internal attractions of the view, I demonstrate that this idea has attractive implications for population ethics. Finally, (...) I show that the view is not subject to John Broome's `greedy neutrality' worry. (shrink) | |
This thesis in an invistigation into the concept of "harm" and its moral relevance. A common view is that an analysis of harm should include a counterfactual condition: an act harms a person iff it makes that person worse off. A common objection to the moral relevance of harm, thus understood, is the non-identity problem. -/- This thesis criticises the counterfactual condition, argues for an alternative analysis and that harm plays two important normative roles. -/- The main ground for rejecting (...) the counterfactual condition is that it has unacceptable consequences in cases of overdetermination and pre-emption. Several modifications to the condition are considered but all fail to solve this problem. -/- According to the alternative analysis to do harm is to perform an act which is responsible for the obtaining of a state of affairs which makes a person’s life go worse. It is argued that should be understood in terms of counterfactual dependence. This claim is defended against counterexamples based on redundant causation. An analysis of is also provided using the notion of a well-being function. It is argued that by introducing this notion it is possible to analyse contributive value without making use of counterfactual comparisons and to solve the non-identity problem. -/- Regarding the normative importance of harm, a popular intuition is that there is an asymmetry in our obligations to future people: that a person would have a life worth living were she to exist is not a reason in favour of creating that person while that a person would have a life not worth living is a reason against creating that person. It is argued that the asymmetry can be classified as a moral option grounded in autonomy. Central to this defence is the suggestion that harm is relevant to understanding autonomy. Autonomy involves partly the freedom to pursue one’s own aims as long as one does no harm. (shrink) | |
In the third edition of ‘Practical Ethics’ (2011), Peter Singer reexamines the so-called “replaceability argument,” according to which merely sentient beings, as opposed to persons (self-conscious and with a robust sense of time), are replaceable—it is in principle permissible to kill them provided that they live pleasant lives that they would not have had otherwise and that they be replaced by equally happy beings. On this view, existence is a benefit and death is not a harm. Singer’s challenge is to (...) avoid (i) the replaceability of persons while preserving the replaceability of merely sentient beings, (ii) the implication that parents are morally required to procreate if they can have happy children, and (iii) to do avoid these implications without having the proposed solution (the “debit view” of preferences) imply negative utilitarianism, or the conclusion that a nonsentient universe is better than any sentient universe. I review Singer’s changing views since 1975 and I argue that his attempt to avoid the replaceability of persons fails: either both non-persons and persons are replaceable or neither are. Singer can only avoid this conclusion by appealing to controversial metaethical claims (attitude-independent moral objectivism) and/or giving up on essential features of utilitarianism. (shrink) | |
abstract John Robertson has famously argued that the right to reproductive autonomy is exceedingly broad in scope. That is, as long as a particular reproductive preference such as having a deaf child is “determinative” of the decision to reproduce then such preferences fall under the protective rubric of reproductive autonomy rights. Importantly, the deafness in question does not constitute a harm to the child thereby wrought since unless the child could be born deaf he or she would otherwise never have (...) existed— his or her prospective parents would simply have chosen to abort. As such, for this child, being born deaf counts as a benefit, albeit of the “backhanded” variety, since the only other practical alternative is nonexistence. In what follows, I want to investigate this argument in detail. The target of my investigation will be the possible future use of gene therapy technology to “disenhance” one's offspring. I intend to show that the apparently unlimited right to reproductive autonomy, that is, the right to choose both the quantity and qualities of future offspring, entailed by the argument from backhanded benefit can in fact be “sidestepped” through considering what sorts of reproductive practices we as a society ought to allow.

Can existence benefit or harm a person? I argue that it cannot. In order for existence to harm a person it has to be the case that existence is worse for the person than never existing. This claim could only be true if it is understood as a claim about the actual, extrinsic value of existence for a person. However, understanding harm in terms of actual extrinsic value comes at the cost of depriving benefits and harms of their normative relevance. (...) I show that a person who is guided by promoting actual extrinsic value can face situations where an outcome is extrinsically better for her but where the same outcome would be extrinsically worse for her were it to obtain. A person who is guided by promoting extrinsic value will in such situations not be able to deliberate about what she should do, prudentially or morally. I conclude that extrinsic value is therefore not something we should be guided by when deliberating about what we should do, and that if harm and benefit is understood in terms of extrinsic value, then we should not be guided by these notions either.

This paper defends the claim that if a person P exists, there can be true positive comparisons between P's existence and P's never having existed at all in terms of what is better or worse for P. If correct, this view will have significant implications for various fundamental issues in population ethics. I try to show how arguments to the contrary fail to take note of a general ambiguity in comparisons when compared alternatives contain their own different standards (or, in (...) the case of non-existence, a lack thereof) on which to base these comparisons. After having answered arguments against the possibility of making positive comparisons, the paper develops a positive account of how to make existence/non-existence comparisons in terms of personal value whilst accepting that a person's non-existence fails to make any contact with the relevant categories of personal value. The guiding idea is the following: When some item satisfies some relevant standard, we can, I argue, infer that it satisfies this standard better than something that fails to satisfy this standard (be this failure due to empirical or conceptual reasons).

I aim to show that the common idea according to which we can assess how bad death is for the person who dies relies on numerous dubious premises. These premises are intuitive from the point of view of dominant views regarding the badness of death. However, unless these premises have been thoroughly justified, we cannot measure the badness of death for the person who dies. In this paper, I will make explicit assumptions that pertain to the alleged level of badness (...) of death. The most important assumption I will address is the assignment of a quantitative value of zero to death, which leads to the conclusion that there are lives not worth living for the affected person. Such a view interprets the idea of a live worth living in quantitative terms. It is in conflict with actual evaluations of relevant people of their lives. (shrink) | |
An interesting question, in both the moral and the legal context, is whether babies born of an infertility treatment-induced supernumerary pregnancy are properly considered to have been harmed. One might wonder how such a question could even arise in the face of data that clearly demonstrate that ITISP leaves an unduly large number of babies blind, deaf, and palsied, and facing lifelong disabilities. In fact, however, a number of arguments, based on the problem of collective form and two forms of (...) the so-called “nonidentity problem,” challenge the claim of harm in the ITISP context. The purpose of the present paper is to establish, as against these arguments, that harm has been imposed on the ITISP-damaged offspring. (shrink) | |
Since certain temporal aspects of the relation between duties, rights, and the interests that rights protect have not been fully theorized, a puzzle arises when we come to consider whether and how entities such as members of future generations, fetuses, deceased persons, and unconscious persons are able to possess rights. This paper evolves a unified structure for attributing the ability to possess rights to such entities. It demonstrates that while, under any cogent theory of rights-attributions, rights and duties must be (...) strictly contemporaneous, the interests that rights protect need not temporally coincide with those rights.
