What does the idea of taking 'the point of view of the universe' tell us about ethics? Lazari-Radek and Singer defend objectivism in ethics, and hedonistic utilitarianism, following Henry Sidgwick's lead. They explore how to justify an ethical theory; conflicts of self-interest and universal benevolence; and whether we should discount the future.

Evolutionary accounts of the origins of human morality may lead us to doubt the truth of our moral judgments. Sidgwick tried to vindicate ethics from this kind of external attack. However, he ended The Methods in despair over another problem—an apparent conflict between rational egoism and universal benevolence, which he called the “dualism of practical reason.” Drawing on Sidgwick, we show that one way of defending objectivity in ethics against Sharon Street’s recent evolutionary critique also puts us in a position (...) to support a bold claim: the dualism of practical reason can be resolved in favor of impartiality.

Sidgwick's defence of esoteric morality has been heavily criticized, for example in Bernard Williams's condemnation of it as 'Government House utilitarianism.' It is also at odds with the idea of morality defended by Kant, Rawls, Bernard Gert, Brad Hooker, and T.M. Scanlon. Yet it does seem to be an implication of consequentialism that it is sometimes right to do in secret what it would not be right to do openly, or to advocate publicly. We defend Sidgwick on this issue, and (...) show that accepting the possibility of esoteric morality makes it possible to explain why we should accept consequentialism, even while we may feel disapproval towards some of its implications.

Utilitarianism may well be the most influential secular ethical theory in the world today. It is also one of the most controversial. It clashes, or is widely thought to clash, with many conventional moral views, and with human rights when they are seen as inviolable. Would it, for example, be right to torture a suspected terrorist in order to prevent an attack that could kill and injure a large number of innocent people? In this Very Short Introduction Peter Singer and (...) Katarzyna de Lazari-Radek provide an authoritative account of the nature of utilitarianism, from its nineteenth-century origins, to its justification and its varieties. Considering how utilitarians can respond to objections that are often regarded as devastating, they explore the utilitarian answer to the question of whether torture can ever be justified. They also discuss what it is that utilitarians should seek to maximize, paying special attention to the classical utilitarian view that only pleasure or happiness is of intrinsic value. Singer and de Lazari-Radek conclude by analysing the continuing importance of utilitarianism in the world, indicating how it is a force for new thinking on contemporary moral challenges like global poverty, the treatment of animals, climate change, reducing the risk of human extinction, end-of-life decisions for terminally-ill patients, and the shift towards assessing the success of government policies in terms of their impact on happiness. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

In the first two volumes of On What Matters, Derek Parfit argues that three major normative theories – Kantianism, Contractualism and Rule Consequentialism – are, in their most defensible forms, compatible, and can be reconciled in what he calls ‘Triple Theory’. This has led many to assume that Parfit does not believe that Act Consequentialism is a defensible form of Consequentialism. We draw on correspondence with Parfit to show that this assumption is incorrect. We then consider Parfit's efforts, in the (...) third volume of On What Matters, to narrow the differences between Act Consequentialism and the triple theory, in part by treating impartial rationality as an external rival to morality, in much the same way that egoism is an external rival to morality. We argue that Parfit's attempts to bridge the gap between Act Consequentialism and Triple Theory meet with only limited success. (shrink)

In this article we argue that it is reasonable to believe that normal vertebrate animals can feel pleasure, and that there is sufficient evidence for a capacity for pleasure in some invertebrates. It follows that the pleasures of animals are morally significant. We argue for that in a few steps. First, we explain why philosophers used to concentrate more on pain rather than pleasure in regard to animals. Second, we define the notion of pleasure and show how it implies to (...) non-human animals. Third we discuss whether animals are conscious beings and how they may feel pleasure. It is true that we do not know exactly how pain and pleasure feel to nonhumans, but this is also true for other humans. Even though we can give a detailed verbal description of what we feel, pains and pleasures are subjective and we do not have any certain insight into what another human is feeling. This limitation should not stop us from behaving in a way that takes into account the fact that both we and many nonhuman animals are beings who can suffer and enjoy. (shrink)

W artykule przedstawiono postać Henry Sidgwicka oraz główne założenia i recepcję jego najważniejszego dzieła The Methods of Ethics. Myśl Sidgwicka, w Polsce znana marginalnie, wpłynęła na współczesną dyskusję filozoficzną w większym stopniu niż teorie Benthama czy Milla i to nie tylko w obrębie utylitaryzmu i konsekwencjalizmu, ale również teorii umowy społecznej czy etyki cnoty. Kwestie moralne, które Sidgwick omawiał w The Methods, w dużym stopniu wynikły z obecnego w historycznych i społecznych realiach wiktoriańskich kryzysu powstałego na tle konfliktu wiary i (...) rozumu. Myśl Sidgwicka zrodziła się z dwu bodaj najbardziej charakterystycznych symptomów owego okresu: zainteresowania nauką i wiary w postęp oraz sceptycyzmu w stosunku do religii. Zarówno w swym wielkim dziele jak i w życiu osobistym Sidgwick dowiódł, iż rzeczą podstawowej wagi było dla niego poszukiwanie prawdy. Świadectwem jego oddania prawdzie było to, że po racjonalnym dojściu do konkluzji sprzecznych z jego utylitarystycznymi „preferencjami”, uznał, iż istnieją dwie ostateczne, nie dające się ze sobą pogodzić zasady moralne — utylitarystyczna zasada życzliwości oraz egoistyczna zasada roztropności.

Utylitarysta hedonista twierdzi, że jego moralnym obowiązkiem jest bezstronne maksymalizowanie przyjemności dla możliwie jak największej liczby istot zdolnych do jej odczuwania. Czym jednak jest owa przyjemność? Henry Sidgwick, filozoficznie najbardziej skrupulatny z hedonistów, definiuje przyjemność jako „pożą dany stan świadomości”. W pierwszej częś ci artykułu przyjrzę się szczegółowo temu, co Sidgwick miał do powiedzenia w kwestii przyjemności. W części drugiej przedstawię niektóre najnowsze wnioski badań empirycznych i zastanowię się, jaki wpływ mogą one mieć na definiowanie przyjemności przez Sidgwicka. Czy pragnienie (...) zawsze towarzyszyć musi przyjemności? Czy świadomość jest koniecznym warunkiem do jej zaistnienia? Czy można porównywać ze sobą przyjemności i cierpienia? Wnioski skłonią mnie do postawienia pytania wyjściowego do kolejnych rozważań o możliwość użycia badań naukowych w dyskusjach filozoficznych. (shrink)

Searching for a rational method of moral reasoning, Henry Sidgwick concludes that practical reason is inconsistent and sometimes directs us to actions that are contradictory. Our ultimate duty is in fact to achieve both our own, particular happiness and the happiness at all. We have duties both of a selfish and of a utilitarian nature. In a situation of conflict, when for the public good we must sacrifice our own interests, reason is not able to indicate to us what course (...) of action should be followed. Finally, we must admit that we cannot entirely rationalize our moral choices. The so-called problem of the dualism of practical reason has been and is discussed by many eminent philosophers, including Roger Crisp, John Skorupskiego and Derek Parfit. This paper is an attempt to highlight the considerations of Sidgwick's dualism of practical reason, the sources of dualism and the contemporary reception of this extremely serious problem for ethics.

Pandemia Covid-19 poddała próbie poglądy bioetyków na temat alokacji ograniczonych zasobów opieki zdrowotnej. Rozważamy stanowiska zajmowane przez organizacje medyczne i krajowe rady etyki we Włoszech, Hiszpanii, Wielkiej Brytanii, Niemczech i Szwecji. W kilku wypowiedziach tych organów pojęcie godności ludzkiej odgrywa kluczową rolę. Twierdzimy, że użycie tego pojęcia nie pomaga w debacie etycznej. Bronimy poglądu, że decyzje dotyczące alokacji ograniczonych zasobów powinny być podejmowane na podstawie zasady maksymalizacji korzyści netto dla dotkniętych nimi osób. Kończymy pytaniem, czy fakt, że w niektórych regionach, (...) po szczepieniu, które stały się powszechnie dostępne, niedobór łóżek szpitalnych był w dużej mierze spowodowany przez członków społeczności, którzy zdecydowali się nie szczepić przeciwko wirusowi wywołującemu Covid-19, powinien odgrywać rolę w przydzielanie zasobów niezaszczepionym osobom, które później zachorowały na ten wirus.

This is a short review of Katarzyna de Lazari-Radek and Peter Singer's book The Point of View of the Universe: Sidgwick and Contemporary Ethics.

Katarzyna de Lazari-Radek and Peter Singer have recently provided an evolutionary argument for utilitarianism. They argue that most of our deontological beliefs were shaped by evolution, from which they conclude that these beliefs are unjustified. By contrast, they maintain that the utilitarian belief that everyone’s well-being matters equally is immune to such debunking arguments because it wasn’t similarly influenced. However, Guy Kahane remarks that this belief lacks substantial content unless it is paired with an account of well-being, (...) and he adds that utilitarian beliefs about wellbeing—e.g. the belief that pleasure is good and pain is bad—were probably shaped by evolution. Logically, de Lazari-Radek and Singer should therefore reject these beliefs along with the deontological beliefs that evolved. The present paper is a defense of their argument. After considering a number of unsuccessful replies to Kahane’s objection, I put forward a more promising solution: de Lazari-Radek and Singer should combine their objectivist view in metaethics with a subjectivist account of well-being, such as the desire theory. Such a hybrid account would tackle Kahane’s challenge because subjective accounts of value are immune from evolutionary debunking arguments. And it would be compatible with utilitarianism, which doesn’t fit very well with metaethical subjectivism. Before concluding, I deal with two concerns that this solution might raise: I argue that the desire theory is actually subjective enough to escape Kahane’s objection, and I deny that retreating to the combination of ethical objectivism and prudential subjectivism is ad hoc.

Katarzyna de Lazari-Radek and Peter Singer argue that evolutionary considerations can resolve Sidgwick’s dualism of practical reason because such considerations debunk moral views that give weight to self-interested or partial considerations but cannot threaten the principle of universal benevolence. I argue that even if we grant these claims, this appeal to evolution is ultimately self-defeating. De Lazari-Radek and Singer face a dilemma. Either their evolutionary argument against partial morality succeeds, but then we need to also (...) give up our conviction that suffering is bad; or there is a way to defend this conviction, but then their argument against partiality fails. Utilitarians, I suggest, should resist the temptation to appeal to evolutionary debunking arguments. (shrink)

This article responds to an argument from Katarzyna de Ladari-Radek and Peter Singer in their article, "The Objectivity of Ethics and the Unity of Practical Reason.".

Katarzyna de Lazari-Radek and Peter Singer’s wonderful book, The Point of View of the Universe: Sidgwick and Contemporary Ethics, contains a wealth of intriguing arguments and compelling ideas. The present paper focuses on areas of continuing dispute. The paper first attacks LazariRadek’s and Singer’s evolutionary debunking arguments against both egoism and parts of common-sense morality. The paper then addresses their discussion of the role of rules in utilitarianism. De Lazari-Radek and Singer concede that rules should (...) constitute our moral decision procedure and our public morality. This paper argues that, if no one should be blamed for complying with the optimal decision procedure and optimal public rules, there are strong reasons to accept that these same rules determine what is morally permissible from what is morally wrong.

The thesis investigates the implications for moral philosophy of research in psychology. In addition to an introduction and concluding remarks, the thesis consists of four chapters, each exploring various more specific challenges or inputs to moral philosophy from cognitive, social, personality, developmental, and evolutionary psychology. Chapter 1 explores and clarifies the issue of whether or not morality is innate. The chapter’s general conclusion is that evolution has equipped us with a basic suite of emotions that shape our moral judgments in (...) important ways. Chapter 2 presents and investigates the challenge presented to deontological ethics by Joshua Greene’s so-called dual process theory. The chapter partly agrees with his conclusion that the dual process view neutralizes some common criticisms against utilitarianism founded on deontological intuitions, but also points to avenues left to explore for deontologists. Chapter 3 focuses on Katarzyna de Lazari-Radek and Peter Singer’s suggestion that utilitarianism is less vulnerable to so-called evolutionary debunking than other moral theories. The chapter is by and large critical of their attempt. In the final chapter 4, attention is directed at the issue of whether or not social psychology has shown that people lack stable character traits, and hence that the virtue ethical view is premised on false or tenuous assumptions. Though this so-called situationist challenge at one time seemed like a serious threat to virtue ethics, the chapter argues for a moderate position, pointing to the fragility of much of the empirical research invoked to substantiate this challenge while also suggesting revisions to the virtue-ethical view as such.

In the first two volumes of On What Matters Derek Parfit argues that there are objective moral truths, and other normative truths about what we have reasons to believe, and to want, and to do. In defending his view, Parfit argues that if there are no objective normative truths, nihilism follows, and nothing matters. He criticizes many leading contemporary philosophers working on ethics, including Simon Blackburn, Stephen Darwall, Allen Gibbard, Frank Jackson, Peter Railton, Mark Schroeder, Michael Smith, and Sharon Street.

ABSTRACTAnthony Skelton, Violetta Igneski and Tracy Isaacs share my view that our obligations to help people in extreme poverty go beyond what is conventionally accepted. Nevertheless, the other contributors argue that my view is too demanding, while noting some tensions between my different writings on this issue. I explain my position, drawing on Sidgwick’s distinction between what someone ought to do, and what we should praise or blame someone for doing or not doing. I also respond to the position that (...) Skelton considers preferable to mine, drawing this time on an argument that Katarzyna de Lazari-Radek and I have made in our recent book, The Point of View of the Universe. I also address Igneski’s concerns about gender inequality, and indicate my broad agreement with Isaacs’ suggestion that effective altruism could benefit from a more co-ordinated approach. (shrink)

Book synopsis: The first full and sustained discussion of Parfit's views on objectivity in ethics Leading philosophers respond to Parfit's criticisms and advance our understanding of the arguments An essential companion volume to Parfit's On What Matters, Volume Three In the first two volumes of On What Matters Derek Parfit argues that there are objective moral truths, and other normative truths about what we have reasons to believe, and to want, and to do. He thus challenges a view of the (...) role of reason in action that can be traced back to David Hume, and is widely assumed to be correct, not only by philosophers but also by economists. In defending his view, Parfit argues that if there are no objective normative truths, nihilism follows, and nothing matters.

Félix Aubé Beaudoin | : Le dilemme darwinien, formulé par Sharon Street, somme les réalistes moraux d’expliquer pourquoi de nombreux jugements qui sont des candidats au statut de vérités morales indépendantes sont aussi ceux qui ont une grande valeur sélective. Les réalistes peuvent soit nier, soit affirmer l’existence d’un lien entre pressions évolutionnistes et vérités morales. Selon Street, la première option mène au scepticisme tandis que la seconde est indéfendable sur le plan scientifique. Peter Singer et Katarzyna de (...) class='Hi'>Lazari-Radek optent pour la première branche de ce dilemme. Dans cet article, la stratégie argumentative qu’ils adoptent — la réponse naturelle — sera soumise à un examen critique. Deux objections seront formulées. La première est d’ordre épistémologique : l’intuitionnisme philosophique défendu par les auteurs fait face à des difficultés majeures. La seconde, plus fondamentale, est que leur solution ne permet pas d’expliquer autrement que par un heureux hasard l’alignement entre les vérités morales et les jugements ayant une valeur sélective. | : According to Sharon Street’s Darwinian Dilemma, moral realists must explain why many judgments that are likely to be independent moral truths are those it would be evolutionarily adaptive to hold. Realists can either deny or assert the existence of a relation between evolutionary influences and moral truths. The first option leads to skepticism, while the second is unacceptable on scientific grounds, says Street. Peter Singer and Katarzyna de Lazari-Radek take the first horn of this dilemma. In this article, the argumentative strategy they adopt — the Natural Reply - is submitted to critical scrutiny. Two objections are raised. The first objection is epistemological : philosophical intuitionism, as defended by the authors, is an untenable position. The second objection is that their solution must appeal to unlikely coincidences to account for the overlap between independent moral truths and evolutionarily adaptive attitudes. (shrink)

Sidgwick's seminal textThe Methods of Ethicsleft off with an unresolved problem that Sidgwick referred to as the dualism of practical reason. The problem is that employing Sidgwick's methodology of rational intuitionism appears to show that there are reasons to favour both egoism and utilitarianism. Katarzyna de Lazari-Radek and Peter Singer offer a solution in the form of an evolutionary debunking argument: the appeal of egoism is explainable in terms of evolutionary theory. I argue that like rational prudence, (...) rational benevolence is subject to debunking arguments and so problematic, but also – and more importantly – that debunking arguments are irrelevant in the debate over the dualism of practical reason on the view of reason and rational intuitionism that Lazari-Radek and Singer embrace. Either both egoism and utilitarianism are debunked, or neither are. If I am right, Sidgwick's dualism is left standing. (shrink)

Consider the idea that moral rules must be suitable for public acknowledgement and acceptance, i.e., that moral rules must be suitable for being ‘widely known and explicitly recognized’, suitable for teaching as part of moral education, suitable for guiding behaviour and reactions to behaviour, and thus suitable for justifying one’s behaviour to others. This idea is now most often associated with John Rawls, who traces it back through Kurt Baier to Kant.[1] My book developing ruleconsequentialism, Ideal Code, Real World, accepted (...) the ‘publicity requirement’ on moral rules.[2] Katarzyna de Lazari-Radek and Peter Singer attack my moral theory on precisely this matter.[3] Here I reply to their attack. The question under discussion is whether moral rightness is a matter of the application of principles or rules that must be suitable for public acceptance. No, answered Henry Sidgwick, holding that perhaps the principles that determine moral right and wrong should be kept secret, because publicizing these principles would not maximize utility.[4] Since I think not-purely utilitarian forms of consequentialism may be more plausible than purely utilitarian forms, let me make the point in terms of consequentialism instead of utilitarianism. The standard form of act-consequentialism is maximizing and ‘global’, i.e., direct about everything.[5] This act-consequentialism includes, among the acts to be evaluated by their consequences, instances of espousing principles, teaching morality, blaming, feeling indignation, feeling guilt, and punishing. On this form of act-consequentialism, an act that maximizes good consequences might be one that others should blame and even punish, since blaming and punishing the agent of the good-maximizing act might also for some reason maximize good consequences. Likewise, on this standard form of act-consequentialism, it may be right to do what it would be right neither to advocate openly nor even to recommend privately. All these ideas are entailed by the kind of act-consequentialism that evaluates, by their consequences, all ‘acts’—in a very broad sense of the term that takes in not only acts of doing or allowing but also acts of blaming, punishing, and recommending. De Lazari-Radek and Singer accept that there are strong consequentialist considerations in support of ‘board support for transparency in ethics’ and avoiding esoteric morality in most circumstances..

This article investigates whether editorial board members of selected economic journals publish their research papers in their ‘own’ journal. Journals were selected from the Journal Citation Report® from the categories Business; Business, Finance; and Economics. Only research articles published between 2012 and 2015 were included in the analysis. We recorded ratios concerning the share of articles authored by editorial board members, the share of editorial board members publishing in their own journals and ratios representing their publication output. The average share (...) of articles authored by editorial board members ranges from 0.6 to 17.5%. The average share of editorial board members publishing in their own journals ranges from 5.6 to 24.4%. Considering only editorial board members publishing in their own journals, the share of their articles in their journals ranges from 8.2 to 71.4%. While the share of board members publishing only in their own journals, to the number of board members publishing in their own journals, the ratio in a quarter of journals is equal to zero, with a maximum reach of 85.7%. All observed ratios are significantly positively correlated with the gap between impact factor and impact factor without Journal Self Cites; and negatively correlated with the Article Influence Score. A cluster of journals in which a high proportion of editorial board members publish and simultaneously these members publish in their own journal at a high rate was identified. (shrink)

In the first part of the article, we show that if $\omega \le \kappa < \lambda$ are cardinals, ${\kappa ^{ < \kappa }} = \kappa$, and λ is weakly compact, then in $V\left[M {\left} \right]$ the tree property at $$\lambda = \left^{V\left[ {\left} \right]} $$ is indestructible under all ${\kappa ^ + }$-cc forcing notions which live in $V\left[ {{\rm{Add}}\left} \right]$, where ${\rm{Add}}\left$ is the Cohen forcing for adding λ-many subsets of κ and $\left$ is the standard Mitchell forcing for (...) obtaining the tree property at $\lambda = \left^{V\left[ {\left} \right]} $. This result has direct applications to Prikry-type forcing notions and generalized cardinal invariants. In the second part, we assume that λ is supercompact and generalize the construction and obtain a model ${V^{\rm{*}}}$, a generic extension of V, in which the tree property at ${\left^{{V^{\rm{*}}}}}$ is indestructible under all ${\kappa ^ + }$-cc forcing notions living in $V\left[ {{\rm{Add}}\left} \right]$, and in addition under all forcing notions living in ${V^{\rm{*}}}$ which are ${\kappa ^ + }$-closed and “liftable” in a prescribed sense.

Proclus of Lycia was one of the greatest philosophers of antiquity, producing the most systematic version of late Neoplatonic thought. He exercised enormous influence on Byzantine, medieval, Renaissance and German Classical philosophy, ranking among the top five of ancient philosophers in terms of the number of preserved works. Despite this he is rarely studied now, the enormous intricacy of his system making the reading of his treatises difficult for beginners. This book provides the first comprehensive introduction to all the basic (...) areas of Proclus' thought. It carefully guides the reader through his metaphysics, theology, epistemology and theory of evil, as well as his sophisticated philosophy of religion. It also sets Proclus in the historical, social and religious context of late antiquity, offering a synthetic account that will appeal to historians and students of ancient religion. (shrink)

This paper offers a conceptual clarification of the phenomenon commonly referred to as categorical perception of color, both in adults and in infants. First, I argue against the common notion of categorical perception as involving a distortion of the perceptual color space. The effects observed in the categorical perception research concern categorical discrimination performance and the underlying processing; they need not directly reflect the relations of color similarity and difference. Moreover, the methodology of the research actually presupposes that the relations (...) of similarity and difference do not vary with languages. The observed categorical perception effects should be conceived independently of the perceptual color space. Second, I challenge the usual opinion that the existing evidence on infant “categorical perception” allows us to conclude that infants perceptually categorize color, and in particular, that they have perceptual categories that resemble the basic color categories of English. Such conclusions rest on an unjustified interpretation of the infant “categorical perception” findings in terms of adult linguistic categorical boundaries. Based on the suggested new understanding, I propose that the phenomenon, as present in infants, should be conceived and examined as a possible explanatory factor with respect to the existing patterns of color naming in languages of the world.

The paper examines the notion, widespread in the contemporary color science, that there are certain hues, specifically focal red, yellow, green and blue, that are unique or privileged in human prelinguistic color perception, all other chromatic hues being perceptually composed of these. I successively consider and reject all motivations that have been provided for this opinion; namely the linguistic, “phenomenological”, and some minor or historical motivations. I conclude that, contrary to the standard opinion, there is no solid reason to claim (...) that the RYGB hues are unique among colors in a sense that would allow for direct neurophysiological explanation. The notion also has no relevance for the construction of perceptual color spaces and is not defensible as an explanatory principle with respect to the existing crosslinguistic patterns of color categorization.
