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 (...) the importance of examining non-separable principles in population ethics. (shrink)

This paper establishes a new impossibility result for welfaristic evaluations when the population varies. We consider a weak version of the repugnant conclusion instead of the commonly used version. It is shown that if a population principle satisfying two reasonable properties avoids the sadistic conclusion, then the weak repugnant conclusion must hold. We use a general variable-population setting where the identities of individuals can matter.

In lieu of an abstract, here is a brief excerpt of the content:MIMETIC SADISM IN THE FICTION OF YUKIO MISHIMA Jerry Piven New York University Mishima Yukio (1925-1970) was one ofthe mostenigmatic authors of the 20th century. Novelist, playwright, actor, exhibiionist —his novels are rife with homoerotic and violent imagery, while his fanatical and nihilistic philosophy calls for a return to a Samurai ethos. Mishima thus attained infamy in Japan and in the West, as his shocking novels inspired hordes ofyoung (...) Japanese into a cult ofMishima worship, while critics who acknowledge his genius are still nervous about his sadistic homosexuality and his suicide. Mishima's works are suffused with erotic bloodshed and misogyny, and Mishima finally ended his life by ritually disemboweling himself. I will make the case that Mishima was incessantly plagued by torturous mimetic frustrations, and that his final act of spilling his blood and intestines can be interpreted as the result of mimetic hatred against his rivals. I also argue that Mishima was fundamentally schizoidal; in Girardian terms, a man whose hypocrisy for the sakeofdesire rendered him an exhibitionistic maskdisguisingmimetic rage and fear. Having previously written about Mishima from a psychoanalytic perspective, I believe that a Girardian approach would often yield drastically different interpretations of identical biographical and literary materials. ' 1I initially wrote on Mishima for several diagnostic assignments at my psychoanalytic institute, the National Psychological Association for Psychoanalysis (NPAP). After considering the psychoanalytic and Girardian approaches, I expanded these original essays using identical material to determine whetherthe interpretations orconclusions would differ; I was struck by the way the same details could provide both remarkable congruences and vast divergences ofperspective. Read side by side, one can find compatible conclusions, but one also finds perceptions ofthe same details that would be difficultto conceive or articulate 70Jeremy Piven Mimesis, misogyny, and maculacy Kimitake Hiraoka was a frail, sickly child before he became the muscular and exhibitionistic novelist Yukio Mishima. His brutal and helpless childhood inaugurated his mimetic complexes: his need to escape the suffocating and diseased environment of his grandmother, his rivalry with her, and his mimetic ideal ofbeauty and muscular invulnerability. Mishima was an unhealthy youth, taken from the arms of his mother before he was two months old, and confined to the sickroom of his grandmother for the first twelve years ofhis life. Under the auspices ofhis tyrannical and ostensively psychotic grandmother, Mishima lived in the dark, could play only female friends (becausetheywere deemed harmless), and could eat only gentle foods. He thus lived an imprisoned life away from his parents, amid the excrescences of his sick and hysterical grandmother until adolescence, when his father "reclaimed him." Mishima later rebelled against this sickly nature, sculpting himself into a statuesque ideal of masculine beauty. He became obsessed with martial arts and the eroticism ofhis own engraved body. His fiction and philosophy were permeated by misogyny, glorification ofGrecian male sexuality and aesthetics, and the repudiation ofanything weak or feminine. He finally killed himselfbefore age could wither his masculine beauty. Mishima's fiction prominently features protagonists who mirror his sickly youth. The autobiographical Confessions of a Mask (Kamen no Kokuhaku) describes the homoerotic development ofthis frail child. Such fraiIcharacters inMishima'sfiction arealwaysdrawneroticallytobeautiful males as both mimetic rivals and models. The narrator of Confessions describes his sexual attraction to a sewage collector, a "ladler of excrement"(8).

Two ofthe original essays will be published inthePsychoanalyticReview in comingmonths: "PhallicNarcissism, Anal Sadism, and Oral Discord: The Case ofYukio Mishima (part I)," and "Narcissistic Revenge and Suicide: The Case ofYukio Mishima (part H)." I am currently translating these articles for publication in Japan.

Critical-Range Utilitarianism is a variant of Total Utilitarianism which can avoid both the Repugnant Conclusion and the Sadistic Conclusion in population ethics. Yet Standard Critical-Range Utilitarianism entails the Weak Sadistic Conclusion, that is, it entails that each population consisting of lives at a bad well-being level is not worse than some population consisting of lives at a good well-being level. In this paper, I defend a version of Critical-Range Utilitarianism which does not entail the Weak (...) Sadistic Conclusion. This is made possible by a fourth category of absolute value in addition to goodness, badness, and neutrality. (shrink)

American Academy of Pediatrics (AAP) and American College of Medical Genetics (ACMG) recently provided two recommendations about predictive genetic testing of children. The Clinical Sequencing Exploratory Research Consortium's Pediatrics Working Group compared these recommendations, focusing on operational and ethical issues specific to decision making for children. Content analysis of the statements addresses two issues: (1) how these recommendations characterize and analyze locus of decision making, as well as the risks and benefits of testing, and (2) whether the guidelines conflict or (...) come to different but compatible conclusions because they consider different testing scenarios. These statements differ in ethically significant ways. AAP/ACMG analyzes risks and benefits using best interests of the child and recommends that, absent ameliorative interventions available during childhood, clinicians should generally decline to order testing. Parents authorize focused tests. ACMG analyzes risks and benefits using the interests of the child and other family members and recommends that sequencing results be examined for additional variants that can lead to ameliorative interventions, regardless of age, which laboratories should report to clinicians who should contextualize the results. Parents must accept additional analysis. The ethical arguments in these statements appear to be in tension with each other. (shrink)

Background Retraction is a mechanism for alerting readers to unreliable material and other problems in the published scientific and scholarly record. Retracted publications generally remain visible and searchable, but the intention of retraction is to mark them as “removed” from the citable record of scholarship. However, in practice, some retracted articles continue to be treated by researchers and the public as valid content as they are often unaware of the retraction. Research over the past decade has identified a number of (...) factors contributing to the unintentional spread of retracted research. The goal of the Reducing the Inadvertent Spread of Retracted Science: Shaping a Research and Implementation Agenda (RISRS) project was to develop an actionable agenda for reducing the inadvertent spread of retracted science. This included identifying how retraction status could be more thoroughly disseminated, and determining what actions are feasible and relevant for particular stakeholders who play a role in the distribution of knowledge. -/- Methods These recommendations were developed as part of a year-long process that included a scoping review of empirical literature and successive rounds of stakeholder consultation, culminating in a three-part online workshop that brought together a diverse body of 65 stakeholders in October–November 2020 to engage in collaborative problem solving and dialogue. Stakeholders held roles such as publishers, editors, researchers, librarians, standards developers, funding program officers, and technologists and worked for institutions such as universities, governmental agencies, funding organizations, publishing houses, libraries, standards organizations, and technology providers. Workshop discussions were seeded by materials derived from stakeholder interviews (N = 47) and short original discussion pieces contributed by stakeholders. The online workshop resulted in a set of recommendations to address the complexities of retracted research throughout the scholarly communications ecosystem. -/- Results The RISRS recommendations are: (1) Develop a systematic cross-industry approach to ensure the public availability of consistent, standardized, interoperable, and timely information about retractions; (2) Recommend a taxonomy of retraction categories/classifications and corresponding retraction metadata that can be adopted by all stakeholders; (3) Develop best practices for coordinating the retraction process to enable timely, fair, unbiased outcomes; and (4) Educate stakeholders about pre- and post-publication stewardship, including retraction and correction of the scholarly record. -/- Conclusions Our stakeholder engagement study led to 4 recommendations to address inadvertent citation of retracted research, and formation of a working group to develop the Communication of Retractions, Removals, and Expressions of Concern (CORREC) Recommended Practice. Further work will be needed to determine how well retractions are currently documented, how retraction of code and datasets impacts related publications, and to identify if retraction metadata (fails to) propagate. Outcomes of all this work should lead to ensuring retracted papers are never cited without awareness of the retraction, and that, in public fora outside of science, retracted papers are not treated as valid scientific outputs.

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 addition (...) also conflicts with avoidance of the repugnant conclusion. This result is a consequence of a similar observation that appears in the earlier literature. (shrink)

In their contribution to the Review of philosophy and psychology (19 March 2010), David Faraci and David Shoemaker object to Susan Wolf’s sane deep self view of moral responsibility, which is supposed to accord with our pretheoretical intuitions about deprived childhood victims better than the plain deep-self view. Wolf’s account hinges on the intuitiveness of a particular example, which asks us to consider JoJo, the son of an evil dictator of a small, undeveloped country who grows up to adopt his (...) father’s sadistic values. Faraci and Shoemaker conduct a survey to test naïve reasoners’ intuitions on this case. From the study results, they draw three general conclusions: (i) that Wolf’s view is false, (ii) that DSV is basically adequate, subject to the addition of a scalar dimension which measures degrees of responsibility, and (iii) that JoJo is partially excused by naïve moral reasoners because he is seen as suffering from a rare and peculiar form of moral ignorance, “different in kind from the moral ignorance people usually experience” (p. 327). I dispute these conclusions and present an alternative interpretation of the study, which defends an externalist, Strawsonian account of moral responsibility, and I use this approach to show that JoJo’s circumstances are inherently extenuating (at least to a significant degree). Unlike Wolf’s view and DSV, my preferred account is capable of accommodating the fact that JoJo’s formative circumstances were the only factor that made a statistically significant difference to the subjects’ moral judgments. This is because it is the only view capable of according any degree of intrinsic relevance to such external factors. (shrink)

Institutions in France are not yet well prepared to respond to allegations of scientific misconduct. Following a serious allegation in late 1997. INSERM,* the primary organization for medical and health-related research in France, began to reflect on this subject, aided by scientists and jurists. The conclusions have resulted in establishing a procedure to be followed in cases of alleged misconduct, and also in reinforcing the application of good laboratory practices within each laboratory. Guidelines for authorship practices and scientific assessment must (...) also be considered. Even though each institution must remain responsible for responding to allegations of scientific misconduct within its doors, INSERM would like to see national, European, and international co-ordination about the methods of such response.

For anyone interested in China—its past, its present, and its future—_The_ _Analects_ (Lunyu) is a must-read. This new translation by renowned East Asian scholar Moss Roberts will offer a fresh interpretation of this classic work, sharpening and clarifying Confucius's positions on ethics, politics, and social organization. While no new edition of _The_ _Analects_ will wholly transform our understanding of Confucius’s teachings, Roberts’s translation attends to the many nuances in the text that are often overlooked, allowing readers a richer understanding of (...) Confucius’ historic and heroic attempt to restore order and morality to government. This edition features a critical introduction by the translator as well as notes on key terms and historical figures, a topical index, and suggestions for further reading in recent English and Chinese scholarship to extend the rich contextual background of the translation. This ambitious new edition of _The_ _Analects_ will enhance the understanding of specialists and newcomers to Confucius alike. (shrink)

The repugnant conclusion can be formulated as follows: For any population consisting of people with very high positive welfare, there is a better population in which everyone has a very low positive welfare, other things being equal. As the name indicates, this conclusion appears unacceptable. Yet it has proven to be surprisingly difficult to find a theory that avoids it without implying other very counterintuitive conclusions. Moreover, the conclusion is a problem not just for total utilitarians or (...) those committed to welfarism but for all moral theories according to which welfare matters at least when all other things are equal, which arguably is a minimal adequacy condition for any moral theory. And, not the least, how to deal with it has implications for the present generations’ duties to future generations and intergenerational justice. The question as to how the repugnant conclusion should be dealt with has thus become one of the cardinal challenges of modern ethics, and the inquiry into what it shows about the nature of ethics has opened up many new avenues for research. This chapter covers the different suggestions in the literature on how to do deal with the conclusion, both on the axiological and on the normative levels. Moreover, the conclusion and different ways of deriving it are explained in detail. (shrink)

This paper provides an axiomatic analysis of sufficientarian social evaluation. Sufficientarianism has emerged as an increasingly important notion of distributive justice. We propose a class of principles that we label generalized critical-level sufficientarian orderings. The distinguishing feature of our new class is that its members exhibit constant critical levels of well-being that are allowed to differ from the threshold of sufficiency. Our basic axiom assigns priority to those below the threshold, a property that is shared by numerous other sufficientarian approaches. (...) When combined with the well-known strong Pareto principle and the assumption that there be a constant critical level, the axiom implies that the critical level cannot be below the threshold. The main results of the paper are characterizations of our new class and an important subclass. As a final observation, we identify the generalized critical-level sufficientarian orderings that permit us to avoid the repugnant conclusion and the sadistic conclusion, which are known as two fundamental challenges in population ethics.

Formal arguments have proven that avoiding the Repugnant Conclusion is impossible without rejecting one or more highly plausible population principles. To many, such proofs establish not only a deep challenge for axiology, but also pose an important practical problem of how policymaking can confidently proceed without resolving any of the central questions of population ethics. Here we offer deflationary responses: first to the practical challenge, and then to the more fundamental challenge for axiology. Regarding the practical challenge, we provide (...) an overview of recent literature that explores the implications for public policy of the Repugnant Conclusion and related puzzles within population ethics, and shows that there is more commonality in the implications of different population axiologies than is generally recognized. The upshot is that uncertainty about population ethics presents no important problem for policymaking, and the importance of population ethics to policymaking has been overstated. We then turn to more fundamental issues about axiology, and describe a new series of formal proofs that undermine the idea that any plausible axiology could avoid the Repugnant Conclusion, including those that are assumed to avoid it in the literature. The philosophical upshot is that the Repugnant Conclusion cannot plausibly be avoided, and so it is a mistake to assume as a constraint on a plausible axiology that it must be avoided, as is assumed by most of the literature in population ethics, including by all of the fundamental impossibility theorems.

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)

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 special case (...) of the repugnant conclusion: namely, the subset of instances of the repugnant conclusion where there is no portion of the population unaffected by the choice between population outcomes (as in Derek Parfit’s original illustration). To avoid an inappropriate focus on only this proper subset of instances of the repugnant conclusion, we formulate a general characterization of the repugnant conclusion. We then prove formally that all leading welfarist axiologies imply this conclusion, including averagism and Ng’s Theory X0 , including probabilistic and ‘very repugnant’ variants that involve the addition of negative lives. We then prove that the full range of axiologies considered by population ethics each imply an extended version of the repugnant conclusion, including axiologies that are incomplete, intransitive, rank-dependent, person-affecting, and/or pluralist. The upshot is that the repugnant conclusion does not ultimately tell against any approach to axiology, and the methodological requirement to avoid the repugnant conclusion should be dropped from population axiology.

The Repugnant Conclusion is a controversial theorem about population size. It states that a sufficiently large population of lives that are barely worth living is better than a smaller population of high quality lives. This is highly counter-intuitive. It implies that we can improve the world by trading quality of life for quantity of lives. Can it be defended? Christopher Cowie explores these questions and unpacks the controversies surrounding the Repugnant Conclusion. He focuses on whether the truth of (...) the Repugnant Conclusion turns - as some have claimed - on the uncomfortable claim that many people's lives are actually bad for them and that even privileged people lead lives that are only just worth living. Highly recommended for those interested in ethics, applied ethics and population studies The Repugnant Conclusion will also be of interest to those in related disciplines such as economics, development studies, politics and international relations.

This paper considers questions that small animals and AI systems raise for utilitarianism. Specifically, if these beings have more welfare than humans and other large animals, then utilitarianism implies that we should prioritize them, all else equal. This could lead to a ‘rebugnant conclusion’, according to which we should, say, create large populations of small animals rather than small populations of large animals. It could also lead to a ‘Pascal’s bugging’, according to which we should, say, prioritize large populations (...) of small animals even if they have a low chance of being sentient. I suggest that utilitarians should accept these implications in theory but might be able to avoid some of them in practice. (shrink)

According to Derek Parfit's well‐known argument, a version of utilitarian moral theory implies the so‐called Repugnant Conclusion. This version of utilitarianism states that other things being equal, it is better if there is a greater total sum of whatever makes life worth living. This view appears to implicate that a world where there is an immense total sum of whatever makes life worth living but where individual people have an exceedingly low quality of life is better than a world (...) where there are considerably less people and a smaller total sum of whatever makes life worth living but where individual people have a high quality of life. Parfit finds the conclusion hard to accept. However, a Swedish philosopher Torbjörn Tännsjö has recently replied to Parfit, arguing that, in fact, the Repugnant Conclusion is perfectly acceptable. Tännsjö's reply, in turn, has been criticized by another Swede, Gustaf Arrhenius. In my paper I evaluate both Tännsjö's reply and Arrhenius' criticism and find both of them insufficient. (shrink)

The Repugnant Conclusion is closer to infinity-based arguments, such as Pascal’s Wager, than it at first appears. Both rely on an unbounded set of payoff comparisons. It is possible to restructure Pascal’s Wager to resemble the Repugnant Conclusion more closely, as the use of infinity is not central to the former. I then consider settings in which the set of comparisons is bounded, so as to differentiate Parfit’s problem from the more general issues involved with very large numbers. (...) We then find the Repugnant Conclusion no longer necessarily arises as a matter of logic rather is an empirical contingency. I then present some plausible intuitions under which the Repugnant Conclusion never arises. The paradoxical nature of Parfit’s Repugnant Conclusion is traced to the simultaneous application of two inconsistent outside observer constructs: one to judge the Repugnant Conclusion as repugnant, and another to define the utility scale for a marginally worthwhile life. Once the two constructs are made consistent, the Repugnant Conclusion can be defused. (shrink)

In Derek Parfit's original formulation the Repugnant Conclusion is characterized as follows: “For any possible population of at least ten billion people, all with a very high quality of life, there must be some much larger imaginable population whose existence, if other things are equal, would be better even though its members have lives that are barely worth living” (Parfit 1984). The Repugnant Conclusion highlights a problem in an area of ethics which has become known as population ethics (...) . The last three decades have witnessed an increasing philosophical interest in questions such as “Is it possible to make the world a better place by creating additional happy creatures?” and “Is there a moral obligation to have children?” The main problem has been to find an adequate theory about the moral value of states of affairs where the number of people, the quality of their lives, and their identities may vary. Since, arguably, any reasonable moral theory has to take these aspects of possible states of affairs into account when determining the normative status of actions, the study of population ethics is of general import for moral theory. As the name indicates, Parfit finds the Repugnant Conclusion unacceptable and many philosophers agree. However, it has been surprisingly difficult to find a theory that avoids the Repugnant Conclusion without implying other equally counterintuitive conclusions. Thus, the question as to how the Repugnant Conclusion should be dealt with and, more generally, what it shows about the nature of ethics has turned the conclusion into one of the cardinal challenges of modern ethics.

The logic of single-conclusion proofs () is introduced. It combines the verification property of proofs with the single valuedness of proof predicate and describes the operations on proofs induced by modus ponens rule and proof checking.

The application to arithmetical inference rules specification and -admissibility testing is considered. We show that the provability in gives the complete admissibility test for (...) the rules which can be specified by schemes in -language. The test is supplied with the ground proof extraction algorithm which eliminates the admissible rules from a -proof by utilizing the information from the corresponding -proofs. (shrink)

The Repugnant Conclusion and its paradoxes pose a significant problem for outcome evaluation. Derek Parfit has suggested that we may be able to resolve this problem by accepting a view he calls ‘Perfectionism’, which gives lexically superior value to ‘the best things in life’. In this paper, I explore perfectionism and its potential to solve this problem. I argue that perfectionism provides neither a sufficient means of avoiding the Repugnant Conclusion nor a full explanation of its repugnance. This (...) is because even lives that are ‘barely worth living’ may contain the best things in life if they also contain sufficient ‘bad things’, such as suffering or frustration. Therefore, perfectionism can only fully explain or avoid the Repugnant Conclusion if combined with other claims, such as that bad things have an asymmetrical value relative to many good things. This combined view faces the objection that any such asymmetry implies Parfit’s ‘Ridiculous Conclusion’. However, I argue that perfectionism itself faces very similar objections, and that these are question-begging against both views. Finally, I show how the combined view that I propose not only explains and avoids the Repugnant Conclusion but also allows us to escape many of its paradoxes as well. (shrink)

According to the Repugnant Conclusion: Compared with the existence of many people who would all have some very high quality of life, there is some much larger number of people whose existence would be better, even though these people would all have lives that were barely worth living. I suggest some ways in which we might be able to avoid this conclusion. I try to defend a strong form of lexical superiority.

The article discusses the structural dynamics of the Covid 19 pandemic and defines it as an essentially finite crisis. However, this definition does not simply come down to the abstract necessity that the pandemic must end at some point, but rather to the fact that the idea of an end has determined the entire course of the pandemic. From the outset, this idea took two antagonistic forms: From the first perspective, the pandemic can only be ended by eliminating the source (...) of the intrusion; from the second perspective, ending the pandemic amounts to society finding a way to adapt to the intrusion. Apart from analyzing the often paradoxical implications of this essentially antagonistic idea for the “objective” evolution of the pandemic in its various phases, the article also demonstrates the inherently sadistic structure of the prevailing societal response. Precisely because this response was aimed at an impossible total normalization, it prepared the ground for the pandemic to possibly mutate into a genuine Anthropocene crisis, the endemic pandemic.

This article explores the main similarities and differences between Derek Parfit’s notion of imprecise comparability and a related notion I have proposed of parity. I argue that the main difference between imprecise comparability and parity can be understood by reference to ‘the standard view’. The standard view claims that 1) differences between cardinally ranked items can always be measured by a scale of units of the relevant value, and 2) all rankings proceed in terms of the trichotomy of ‘better than’, (...) ‘worse than’, and ‘equally good’. Imprecise comparability, which can be understood in terms of the more familiar notions of cardinality and incommensurability, rejects only the first claim while parity rejects both claims of the standard view. -/- I then argue that insofar as those attracted to imprecise comparability assume that all rankings are trichotomous, as Parfit appears to, the view should be rejected. This is because imprecise equality is not a form of equality but is a sui generis ‘fourth’ basic way in which items can be ranked. We should, I argue, understand imprecise equality as parity, and imprecise comparability as entailing ‘tetrachotomy’ – that if two items are comparable, one must better than, worse than, equal to, or on a par with the other. Thus those attracted to the idea that cardinality can be imprecise should abandon trichotomy and accept parity and tetrachotomy instead. -/- Finally, I illustrate the difference between Parfit’s trichotomous notion of imprecise comparability and parity by examining how each notion might be employed in different solutions to the problem posed by the Repugnant Conclusion in population ethics. I suggest that parity provides the arguably more ecumenical solution to the problem. (shrink)

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)

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. I (...) demonstrate that Temkin appeals to two conflicting notions of aggregation. I then spell out the consequences of these results for different interpretations of Griffin's suggestion regarding population ethics. None of them comes out very successful, but perhaps they nevertheless retain some interest. (shrink)

This paper explores the connection between Kant’s first antinomy and the set-theoretical paradox of the largest cardinal. The lesson to be drawn is that we should refrain from reifying the collections that generate the antinomies: the collection of all spatio-temporal objects in the case of Kant’s first antinomy, the collection of all objects whatsoever in the case of the Cantorian paradox. This conclusion is not only one that we are entitled to draw but also one that does not generate (...) new philosophical problems of its own. In this respect it is more attractive than other contemporary reactions to the paradoxes of set theory. (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.

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.
