  1. Population Ethics and Metaethics.Gustaf Arrhenius - 2012 - Iride: Filosofia e Discussione Pubblica 25 (1):35-44.
    This paper focuses on the relations between population ethics and metaethics. Population ethics gives rise to well-known paradoxes, such as the paradox of mere addition. After presenting a version of this paradox, it is argued that a different way to dismantle it might be by considering it as a way to change our standard view of justification in moral theory. Two possible views are considered: a non-cognitivist approach to justification and to the explanation of (...)

    Introductory Note. Population Ethics: The Unavoidability of the Quality of Life and the Ensuing Paradoxes.Gianfranco Pellegrino - 2012 - Iride: Filosofia e Discussione Pubblica 25 (1):27-34.
    Population ethics is defined and presented, and some of the paradoxes it encapsulates are spelled out. It is argued that the concept of the quality of a life or of a life worth living can- not be avoided if inquiry on many relevant ethical and political topics is to be pursued in a theoretically fitting mode. In particular, the article deals with the asymmetry between rea- sons for not creating unhappy lives and reasons for creating happy lives, the well-known (...)

  3. How Lives Measure Up.Molly Gardner & Justin Weinberg - 2013 - Acta Analytica 28 (1):31-48.
    The quality of a life is typically understood as a function of the actual goods and bads in it, that is, its actual value. Likewise, the value of a population is typically taken to be a function of the actual value of the lives in it. We introduce an alternative understanding of life quality: adjusted value. A life’s adjusted value is a function of its actual value and its ideal value (the best value it could have had). The concept (...)

    (1 other version)The Multiverse Theodicy Meets Population Ethics.Han Li & Bradford Saad - 2023 - Ergo: An Open Access Journal of Philosophy 10.
    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 (...)

  5. Mere Addition and the Separateness of Persons.Matthew Rendall - 2015 - Journal of Philosophy 112 (8):442-455.
    How can we resist the repugnant conclusion? James Griffin has plausibly suggested that part way through the sequence we may reach a world—let us call it “J”—in which the lives are lexically superior to those that follow. If it would be preferable to live a single life in J than through any number of lives in the next one, then it would be strange to judge K the better world. Instead, we may reasonably “suspend addition” and judge J (...)

  6. Path Independence and a Persistent Paradox of Population Ethics.Rush T. Stewart - forthcoming - Journal of Philosophy.
    In the face of an impossibility result, some assumption must be relaxed. The Mere Addition Paradox is an impossibility result in population ethics. Here, I explore substantially weakening the decision-theoretic assumptions involved. The central finding is that the Mere Addition Paradox persists even in the general framework of choice functions when we assume Path Independence as a minimal decision-theoretic constraint. Choice functions can be thought of either as generalizing the standard axiological assumption of a binary (...)

    Intransitivity and future generations: Debunking Parfit's mere addition paradox.Kai M. A. Chan - 2003 - Journal of Applied Philosophy 20 (2):187–200.
    Duties to future persons contribute critically to many important contemporaneous ethical dilemmas, such as environmental protection, contraception, abortion, and population policy. Yet this area of ethics is mired in paradoxes. It appeared that any principle for dealing with future persons encountered Kavka's paradox of future individuals, Parfit's repugnant conclusion, or an indefensible asymmetry. In 1976, Singer proposed a utilitarian solution that seemed to avoid the above trio of obstacles, but Parfit so successfully demonstrated the unacceptability of this position (...)

    One of Derek Parfit’s greatest legacies was the search for Theory X, a theory of population ethics that avoided all the implausible conclusions and paradoxes that have dogged the field since its inception: the Absurd Conclusion, the Repugnant Conclusion, the Non-Identity Problem, and the Mere Addition Paradox. In recent years, it has been argued that this search is doomed to failure and no satisfactory population axiology is possible. This chapter reviews Parfit’s life’s work in the (...)

    Conditional normative reasoning as a fragment of HOL.Xavier Parent & Christoph Benzmüller - 2024 - Journal of Applied Non-Classical Logics 34 (4):561-592.
    We report on the mechanisation of (preference-based) conditional normative reasoning. Our focus is on Åqvist's system E for conditional obligation, and its extensions. Our mechanisation is achieved via a shallow semantical embedding in Isabelle/HOL. We consider two possible uses of the framework. The first one is as a tool for meta-reasoning about the considered logic. We employ it for the automated verification of deontic correspondences (broadly conceived) and related matters, analogous to what has been previously achieved for the modal logic (...)

    A set of arguments shows that either the Repugnant Conclusion and its variants are true or the better-than relation isn't transitive. Which is it? This is the most important question in population ethics. The answer will point the way to Parfit's elusive Theory X.

    Population axiology concerns how to evaluate populations in regard to their goodness, that is, how to order populations by the relations “is better than” and “is as good as”. This field has been riddled with “paradoxes” which seem to show that our considered beliefs are inconsistent in cases where the number of people and their welfare varies. Already in Derek Parfit’s seminal contribution to the topic, an informal paradox — the Mere Addition Paradox — was presented and (...)

    Population axiology concerns how to evaluate populations in regard to their goodness, that is, how to order populations by the relations “is better than” and “is as good as”. This field has been riddled with impossibility results which seem to show that our considered beliefs are inconsistent in cases where the number of people and their welfare varies.1 All of these results have one thing in common, however. They all involve an adequacy condition that rules out Derek Parfit’s (...) Conclusion: The Repugnant Conclusion: For any perfectly equal population with very high positive welfare, there is a population with very low positive welfare which is better, other things being equal.2 1 The informal Mere Addition Paradox in Parfit (1984), pp. 419ff is the locus classicus. For an informal proof of a similar result with stronger assumptions, see Ng (1989), p. 240. A formal proof with slightly stronger assumptions than Ng’s can be found in Blackorby and Donaldson (1991). For theorems with much weaker assumptions, see my (1999), (2000b), and especially (2000a), (2001), and (2009). 2 See Parfit (1984), p. 388. My formulation is more general than Parfit’s apart from that he doesn’t demand that the people with very high welfare are equally well off. Expressions such as “a population with very high positive welfare”, “a population with very low positive welfare”, etc., are elliptical for the more cumbersome phrases “a population consisting only of lives with..

  13. An Intrapersonal Addition Paradox.Jacob M. Nebel - 2018 - Ethics 129 (2):309-343.
    I present a new argument for the repugnant conclusion. The core of the argument is a risky, intrapersonal analogue of the mere addition paradox. The argument is important for three reasons. First, some solutions to Parfit’s original puzzle do not obviously generalize to the intrapersonal puzzle in a plausible way. Second, it raises independently important questions about how to make decisions under uncertainty for the sake of people whose existence might depend on what we do. And, third, (...)

    Value Incommensurability: Ethics, Risk. And Decision-Making.Henrik Andersson & Anders Herlitz (eds.) - 2021 - New York, NY: Routledge.
    Incommensurability is the impossibility to determine how two options relate to each other in terms of conventional comparative relations. This book features new research on incommensurability from philosophers who have shaped the field into what it is today, including John Broome, Ruth Chang and Wlodek Rabinowicz. The book covers four aspects relating to incommensurability. In the first part, the contributors synthesize research on the competing views of how to best explain incommensurability. Part II illustrates how incommensurability can help us deal (...)

    Anti‐natalism is incompatible with Theory X.Fumitake Yoshizawa - 2024 - Bioethics 38 (2):114-120.
    The anti‐natalist philosopher David Benatar defends a position asserting that all life is harmful, and that it is, therefore, wrong to have children. In this paper, I critique Benatar's less‐discussed claim that his anti‐natalism provides solutions to population ethics problems, such as the Non‐Identity Problem, the Repugnant Conclusion, and the Mere Addition Problem, all of which are presented in Derek Parfit's Reasons and Persons. Since the publication of his Better Never to Have Been, Benatar has continued (...)

  16. Millian superiorities and the repugnant conclusion.Karsten Klint Jensen - 2008 - Utilitas 20 (3):279-300.
    James Griffin has considered a form of superiority in value that is weaker than lexical priority as a possible remedy to the Repugnant Conclusion. In this article, I demonstrate that, in a context where value is additive, this weaker form collapses into the stronger form of superiority. And in a context where value is non-additive, weak superiority does not amount to a radical value difference at all. These results are applied on one of Larry Temkin's cases against transitivity.

    This paper argues that the Repugnant Conclusion which the Mere Addition Paradox generates is not the same as the one which a sum-aggregative view like impersonal total utilitarianism leads to, but a slightly more moderate version of it. Given a spectrum of outcomes {A, B, C, …, X, Y, Z} such that in each of them there is a population that is twice as large as the previous one and has a level of wellbeing that is (...)

    Degrees of commensurability and the repugnant conclusion.Alan Hájek & Wlodek Rabinowicz - 2021 - Noûs 56 (4):897-919.
    Two objects of valuation are said to be incommensurable if neither is better than the other, nor are they equally good. This negative, coarse-grained characterization fails to capture the nuanced structure of incommensurability. We argue that our evaluative resources are far richer than orthodoxy recognizes. We model value comparisons with the corresponding class of permissible preference orderings. Then, making use of our model, we introduce a potentially infinite set of degrees of approximation to better, worse, and equally good, which we (...)

  19. What calibrating variable-value population ethics suggests.Dean Spears & H. Orri Stefánsson - 2024 - Economics and Philosophy 40 (3):673-684.
    Variable-Value axiologies avoid Parfit’s Repugnant Conclusion while satisfying some weak instances of the Mere Addition principle. We apply calibration methods to two leading members of the family of Variable-Value views conditional upon: first, a very weak instance of Mere Addition and, second, some plausible empirical assumptions about the size and welfare of the intertemporal world population. We find that such facts calibrate these two Variable-Value views to be nearly totalist, and therefore imply conclusions that (...)

  20. The Axiomatic Approach to Population Ethics.Charles Blackorby, Walter Bossert & David Donaldson - 2002 - Politics, Philosophy and Economics 2 (3):342-381.
    This article examines several families of population principles in the light of a set of axioms. In addition to the critical-level utilitarian, number-sensitive critical-level utilitarian, and number-dampened utilitarian families and their generalized counterparts, we consider the restricted number-dampened family and introduce two new ones: the restricted critical-level and restricted number-dependent critical-level families. Subsets of the restricted families have non-negative critical levels, avoid the `repugnant conclusion' and satisfy the axiom priority for lives worth living, but violate an important (...)

  22. Mere Addition and Two Trilemmas of Population Ethics.Erik Carlson - 1998 - Economics and Philosophy 14 (2):283.
    A principal aim of the branch of ethics called ‘population theory’ or ‘population ethics’ is to find a plausible welfarist axiology, capable of comparing total outcomes with respect to value. This has proved an exceedingly difficult task. In this paper I shall state and discuss two ‘trilemmas’, or choices between three unappealing alternatives, which the population ethicist must face. The first trilemma is not new. It originates with Derek Parfit's well-known ‘Mere Addition Paradox’, and was (...)

    The implications of the repugnant conclusion for consequentialist theories, such as total utilitarianism, have been extensively discussed since the work of Derek Parfit. These discussions make the paradoxes of population ethics depend on welfarist conditions, like the dominance condition (or the Pareto Principle). Thus, one might think that the repugnant conclusion is not a practical problem for deontologists, who deny that we always ought to do what produces the most aggregate welfare.

    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 theory includes (i) the denial that being better than is transitive and (ii) the “Conflation Principle,” according to which alternative B is hedonically better than alternative C if it would be better for someone to have all the (...)

    Population axiology includes two major arguments. The first is the repugnant conclusion, which was originally formulated by Derek Parfit to criticize total utilitarianism. The second is the sadistic conclusion. In this study, I demonstrate that no additively separable principle can avoid both repugnant and sadistic conclusions if individual moral values have no upper bound. This impossibility holds not only for utilitarian principles but also for any population principles that guarantee the separability of people’s well-being. I emphasize (...)

    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. Parfit suggests that this feature of value comparisons opens up a way of avoiding the Repugnant Conclusion without implying other counterintuitive conclusions, and thus solves one of the major challenges in ethics. In this (...)

    The spectre of the repugnant conclusion and the search for a population axiology that avoids it has endured as a focus of population ethics. This is in part because the repugnant conclusion is often interpreted as a defining problem for totalism, while the implications of averagism and related views are taken to illustrate the theoretical cost of avoiding the repugnant conclusion. However, we show that this interpretation cannot be sustained unless one focuses only on a (...)

    Values are incommensurable when they cannot be measured on a single cardinal scale. Many philosophers suggest that incommensurability can help us solve the problems of population ethics. I agree. But some philosophers claim that populations bear incommensurable values merely because they contain different numbers of people, perhaps within some range. I argue that mere differences in how many people exist, even within some range, do not suffice for incommensurability. I argue that the intuitive neutrality of creating happy people (...)

    Recently, Derek Parfit has offered a novel solution to the “Repugnant Conclusion” that compared with the existence of many people whose quality of life would be very high, there is some much larger number of people whose existence would be better but whose lives would be barely worth living. On this solution, qualitative differences between two populations will often entail that the populations are merely “imprecisely” comparable. According to Parfit, this fact allows us to avoid the Repugnant Conclusion (...)

    The person-affecting restriction, in its slogan form, states that an outcome can be better than another only if it is better for someone. It has a strong intuitive appeal and several theorists have suggested that it avoids certain counterintuitive implications in population ethics. At the same time, the restriction has highly counterintuitive implications and yields non-transitive orderings in some nonidentity cases. Many theorists have taken this criticism to be decisive. Recently, however, there have been some reformulations of the restriction, (...)

    Separability in Population Ethics.Teruji Thomas - 2022 - In Gustaf Arrhenius, Krister Bykvist, Tim Campbell & Elizabeth Finneron-Burns, The Oxford Handbook of Population Ethics. Oxford University Press. pp. 271-295.
    Separability is roughly the principle that, in comparing the value of two outcomes, one can ignore any people whose existence and welfare are unaffected. Separability is both antecedently plausible, at least as a principle of beneficence, and surprisingly powerful; it is the key to some of the best positive arguments in population ethics. This chapter surveys the motivations for and consequences of separability. In particular, it presents an ‘additivity theorem’ which explains how separability leads to total utilitarianism and closely (...)

    A Solution to the Purported Non-Transitivity of Normative Evaluation.Alan Carter - 2015 - Journal of Philosophy 112 (1):23-45.
    Derek Parfit presents his Mere Addition Paradox in order to demonstrate that it is extremely difficult to avoid the Repugnant Conclusion. And in order to avoid it, Parfit has embraced perfectionism. However, Stuart Rachels and Larry Temkin, taking their lead from Parfit, have concluded, instead, that the Repugnant Conclusion can be avoided by denying the axiom of transitivity with respect to the all-things-considered-better-than relation. But this seems to present a major challenge to how we evaluate normatively. (...)

    Why should ‘better than’ be transitive? The leading answer in ethics is that values do not change with context. But this cannot be the entire source of transitivity, I argue, since transitivity can fail even if values never change, so long as they are complex, with multiple dimensions combined non-additively. I conclude by exploring a new hypothesis: that all alleged cases of nontransitive betterness, such as Parfit’s Repugnant Conclusion, can and should be modelled as the result of complexity, not (...)

  41. Egalitarianism and the putative paradoxes of population ethics.Torbjörn Tännsjö - 2008 - Utilitas 20 (2):187-198.
    The repugnant conclusion is acceptable from the point of view of total utilitarianism. Total utilitarians do not seem to be bothered with it. They feel that it is in no way repugnant. To me, a hard-nosed total utilitarian, this settles the case. However, if, sometimes, I doubt that total utilitarianism has the final say in ethics, and tend to think that there may be something to some objection to it or another, it is the objection to it brought (...)

    Multi-species Population Ethics with Critical Levels.Susumu Cato & Shu Ishida - forthcoming - Erkenntnis:1-20.
    This paper explores the notion of species-relative critical levels, which is a crucial ethical issue in multi-species population ethics. First, the formal conditions are provided under which there are species-relative critical levels (e.g., the critical level for human beings is different from that for non-human beings). In particular, we find it a salient question of animal ethics whether the existence of a human being is morally better than that of a non-human animal when their utility levels are the same. (...)

    The Repugnant Conclusion: Essays on Population Ethics.Torbjörn Tännsjö & Jesper Ryberg (eds.) - 2004 - Kluwer Academic Publishers.
    Most people (including moral philosophers), when faced with the fact that some of their cherished moral views lead up to the Repugnant Conclusion, feel that they have to revise their moral outlook. However, it is a moot question as to how this should be done. It is not an easy thing to say how one should avoid the Repugnant Conclusion, without having to face even more serious implications from one's basic moral outlook. Several such attempts are presented in (...)

    The Neutral Level for Existence.John Broome - 2004 - In Weighing lives. New York: Oxford University Press.
    This chapter demonstrates how the assumptions made so far in the book imply that there is a single neutral level for existence. That is, there is a single level of wellbeing such that adding a person at that level is neither better nor worse than not adding her. It explains how this conclusion conflicts strongly with an intuition shared by many people: the ‘neutrality intuition’ that adding a person to the world’s population is generally ethically neutral. It uses examples (...)

  46. Additively-separable and rank-discounted variable-population social welfare functions: A characterization.Dean Spears & H. Orri Stefansson - 2021 - Economic Letters 203:1-3.
    Economic policy evaluations require social welfare functions for variable-size populations. Two important candidates are critical-level generalized utilitarianism (CLGU) and rank-discounted critical-level generalized utilitarianism, which was recently characterized by Asheim and Zuber (2014) (AZ). AZ introduce a novel axiom, existence of egalitarian equivalence (EEE). First, we show that, under some uncontroversial criteria for a plausible social welfare relation, EEE suffices to rule out the Repugnant Conclusion of population ethics (without AZ’s other novel axioms). Second, we provide a new characterization (...)

    A Theory of Value and Obligation.Robin Attfield - 2020 - Routledge.
    Originally published in 1987 and re-issued in 2020 with a new Preface, this book presents and elaborates interrelated solutions to a number of problems in moral philosophy, from the location of intrinsic value and the nature of a worthwhile life, via the limits of obligation and the nature of justice, to the status of moral utterances. After developing a biocentric account of moral standing, the author locates worthwhile life in the development of the generic capacities of a creature, whether human (...)

  48. (1 other version)Counterexamples to the transitivity of better than.Stuart Rachels - 1998 - Australasian Journal of Philosophy 76 (1):71 – 83.
    Ethicists and economists commonly assume that if A is all things considered better than B, and B is all things considered better than C, then A is all things considered better than C. Call this principle Transitivity. Although it has great conceptual, intuitive, and empirical appeal, I argue against it. Larry S. Temkin explains how three types of ethical principle, which cannot be dismissed a priori, threaten Transitivity: (a) principles implying that in some cases different factors are relevant to comparing (...)

    Revisiting variable-value population principles.Walter Bossert, Susumu Cato & Kohei Kamaga - 2023 - Economics and Philosophy 39 (3):468-484.
    We examine a general class of variable-value population principles. Our particular focus is on the extent to which such principles can avoid the repugnant and sadistic conclusions. We show that if a mild limit property is imposed, avoidance of the repugnant conclusion implies the sadistic conclusion. This result generalizes earlier observations by showing that they apply to a substantially larger class of principles. Our second theorem states that, under the limit property, the axiom of mere (...) also conflicts with avoidance of the repugnant conclusion. This result is a consequence of a similar observation that appears in the earlier literature. (shrink)

    Medical Assistance in Dying for Persons Suffering Solely from Mental Illness in Canada.Chloe Eunice Panganiban & Srushhti Trivedi - 2025 - Voices in Bioethics 11.
    Photo ID 71252867© Stepan Popov| Dreamstime.com Abstract While Medical Assistance in Dying (MAiD) has been legalized in Canada since 2016, it still excludes eligibility for persons who have mental illness as a sole underlying medical condition. This temporary exclusion was set to expire on March 17th, 2024, but was set 3 years further back by the Government of Canada to March 17th, 2027. This paper presents a critical appraisal of the case of MAiD for individuals with mental illness as the (...)
