Anyone who has read Plato’s Republic knows it has a lot to say about mathematics. But why? I shall not be satisfied with the answer that the future rulers of the ideal city are to be educated in mathematics, so Plato is bound to give some space to the subject. I want to know why the rulers are to be educated in mathematics. More pointedly, why are they required to study so much mathematics, for so long?

It has become increasingly common recently to construe human natureas setting some pretty stringent limits to moral endeavour. Many consequentialists, in particular, take considerations concerning human nature to defeat certain demanding norms that would otherwise follow from their theory.One argument is that certain commitments ground psychological incapacitiesthat prevent us from doing what would maximize the good. Another is that we would be likely to suffer some kind of psychological demoralization if we tried to become significantly more selfless. I argue that (...) influential versions of both of these arguments underestimate our deliberative resources, and also fail to examine the kind of moral sources that may be able to sustain rigorous moral endeavour. Pessimism about our capacities for such endeavour results from the neglect of these factors, rather than from uncovering any significant limitations in human nature. (shrink)

After MacIntyre contains original essays by leading moral and political philosophers who assess both the merits and limitations of Alasdair MacIntyre's work. Among the themes explored here are MacIntyre's historical arguments about the sources of the failure of modernity; the validity and relevance of his attempt to reinstate the ideas of Aristotle and Aquinas as central to any satisfactory moral understanding; the effectiveness of his critique of modern liberalism; and the adequacy of key concepts, such as tradition and practice, in (...) his analyses and arguments. In addition, MacIntyre responds in a substantial essay to the issues raised by the other contributors. (shrink)

In this paper, I argue that if we understand Levinas’s Desire of the Other as gift, we can understand it as joyful—that is, as celebratory. After presenting Levinas’s conception of Desire, I consider his claim, found in Otherwise than Being, that the self is a hostage to the Other, and I contend that, paradoxical as it may seem, being a hostage to the Other is actually liberating. Then, drawing on insights Richard Kearney offers in Reimagining the Sacred, I argue for (...) understanding Desire as a gift that is the condition of possibility for joy. If I offer hospitality to the Other, I thereby accept the gift that makes joy possible, and this joy is not egoistic but is the proper response to the gift. Finally, I ask whether Desire can be joyful in practice, given that the pure gift is an originary condition and never a historical one, and I conclude that imperfect joy remains possible. Moreover, this imperfect joy is better than any solitary enjoyment I might experience in the total absence of the Other. (shrink)

For several decades, there has been a debate in the philosophical literature concerning whether those of us who live in developed countries are morally required to give some of our money to aid agencies. Many contributors to this debate have apparently taken it that one may simply assume that the effects of the work such agencies do are overwhelmingly positive. If one turns to the literature on such agencies that has emerged in recent decades, however, one finds a number of (...) concerns about such agencies and the work they do that put that assumption in serious doubt. This situation raises a number of pressing questions, many of which have received little or no attention from philosophers. After articulating a number of those questions, I focus mainly on what I call the ‘Epistemic Question (for potential contributors to aid agencies)’: How can those of us who are not experts in international aid arrive at an estimate concerning the effects of the work aid agencies do that we have at least some good reason to believe accurate?

One relatively straightforward way in which academics could have more impact on global poverty is by doing more to help people make wise decisions about issues relevant to such poverty. Academics could do this by conducting appropriate kinds of research on those issues and sharing what they have learned with the relevant decision makers in accessible ways. But aren’t academics already doing this? In the case of many of those issues, I think the appropriate answer would be that they could (...) do so much better. As an illustration, I examine the academic input into one decision about an issue concerning global poverty in some detail in this paper. I argue that that input has been seriously deficient, and suggest some ways in which it might be improved. Building on this discussion, I then formulate two questions that can be applied to any such decision, answers to which would indicate the quality of the input academics are currently providing. In cases where that input is deficient, and the decision in question an important one, I suggest that academics consider organising themselves in ways that will improve that input. I finish by briefly discussing how Academics Stand Against Poverty might help them do so. (shrink)

One of the ways in which transnational medical agencies (TMAs) such as Medicins Sans Frontieres aim to increase the access of the global poor to health services is by supplying medical aid to people who need it in developing countries. The moral imperative supporting such work is clear enough, but a variety of factors can make such work difficult. One of those factors is the wrongdoing of other agents and agencies. For as a result of such wrongdoing, the attempt to (...) supply medical aid can sometimes lead to significant negative effects. What should TMAs do in such situations? On one view, TMAs should take account of any negative effects arising from the wrongdoing of others in just the same way in which they take account of negative effects arising more directly from their own actions, or from natural forces. To many people, this view seems wrong. In this paper, I articulate and discuss several different reasons why one might think this. In doing so, I hope to contribute to a debate about the more general question of how TMAs should respond to the wrongdoing of others. (shrink)

Over the last few decades, psychologists have amassed a great deal of evidence that our thinking is strongly influenced by a number of biases. This research appears to have important implications for moral methodology. It seems likely that these biases affect our thinking about moral issues, and a fuller awareness of them might help us to find ways to counteract their influence, and so to improve our moral thinking. And yet there is little or no reference to such biases in (...) the philosophical literature on many pressing, substantive moral questions. In this paper, I make a start on repairing this omission in relation to one such question, the 'Aid Question', which concerns how much, if anything, we are morally required to give to aid agencies. I begin by sketching a number of biases that seem particularly likely to affect our thinking about that question. I then go on to review the psychological research on 'debiasing' - that is, on attempts to counteract the influence of such biases. And finally I discuss and illustrate certain strategies for counteracting the influence of the biases in question on our thinking about the Aid Question. (shrink)

The Authority Account provides a new explanation why commonsense morality contains prudential options—options that permit agents to perform actions that promote their own wellbeing more than the action they have most reason to do, from the moral point of view. At the core of that explanation are two claims. The first is that moral requirements are traditionally widely taken to have an authoritative status; that is, to be rules that morality imposes by right. The second is that in order for (...) moral requirements to have such a status, morality must contain prudential options. If both of these claims are true, then they will create a pressure to think of morality as containing prudential options. And according to the Authority Account, the fact that commonsense morality contains such options is the result of this pressure. (shrink)

This article examines Kamel Daoud’s treatment of solidarity and the absurd in Meursault, contre-enquête and posits that the question of how to live in solidarity with others is central to the novel, although the word ‘solidarity’ never appears in it. After recalling Camus’s discussion of the absurd in Le Mythe de Sisyphe and of solidarity in L’Homme révolté, the article examines the manner in which Haroun, Daoud’s narrator and the brother of the Arab Meursault killed in L’Étranger, reveals his own (...) failures of solidarity. He justly criticizes Meursault for privileging his confrontation with the absurd over the death of the Arab he did not even name, but Haroun too has killed. Haroun has, however, a greater understanding of solidarity than his fellows: he at least recognizes that murder is significant. He thus joins Meursault as an unworthy prophet who proclaims the absurd while surrounded by people who flee from it—and proclaiming the absurd can be a gesture of solidarity when one speaks for others, as Haroun speaks for his brother Moussa. Daoud’s novel reminds us that there are no final answers telling us how to live in solidarity with others and that we must do so all the same. (shrink)

The Promise of Friendship investigates what makes friendship possible and good for human beings. In dialogue with authors ranging from Aristotle and Montaigne to Proust, Levinas, and Derrida, Sarah Horton argues that friendship is suited to our finitude—that is, to the limits within which human beings live—and proposes a novel understanding of friendship as translation: friends translate the world for each other so that each one experiences the world not as the other does but in light of the friend's (...) always-unknowable experience. The very distance between friends that makes it impossible for them to know each other wholly also makes it possible for them to be transformed by friendship. Friendship, then, is possible and good for those who love precisely that they can never wholly know the friend. Friendship is a profound, mutual self-giving that highlights the irreplaceability of each person, fundamentally shapes the self, and is one of the greatest joys of human existence. (shrink)

Some moral principles require agents to do more than their fair share of a common task, if others won’t do their fair share – each agent’s fair share being what they would be required to do if all contributed as they should. This seems to provide a strong basis for objecting to such principles. For it seems unfair to require agents who have already done their fair share to do more, just because other agents won’t do their fair share. The (...) philosopher who has written most about this issue, however, Liam Murphy, argues that it is not unfair to do so, at least in the standard sense of that term. In this paper, I give Murphy’s reasons for saying this, explain why I think he’s wrong, and then say a little about why this issue might be important. (shrink)

This essay examines the analysis of language in The Concept of Anxiety and argues that language ultimately reveals itself as both dangerous and salvific. The pseudonymous author, Vigilius Haufniensis, is suspicious of language, for it divides the individual from herself and thereby makes possible the self-forgetfulness of objective chatter. Indeed, this warning (which commenters have tended to follow uncritically) is a legitimate one – yet it fails to grasp that by rendering the self other than itself, language constitutes the self. (...) In other words, the individual’s very existence depends on language. Moreover, the attempt to establish oneself as absolutely self-identical is precisely sin. Language opens us to alterity, and for this reason the demonic cannot endure it and seeks to control it. Language is uncontrollable, however, to the point that no sign permits us to be certain that we have rightly distinguished good from evil, the salvific from the demonic – and salvation can come only if we renounce the attempt to establish distinctions that are beyond our power. By employing a pseudonymous figure who views language with suspicion, Kierkegaard shows that language is dangerous, even deadly, but also allows us to realize that language is the condition of possibility for salvation.

Translation (French to English) of Emmanuel Falque's "Le fou désincarné." I also wrote a translator's note, placed at the conclusion of the article. Phenomenology must begin to acknowledge the organic, animal nature of the body instead of focusing only on the pure subjectivity of the flesh. Mediating between Descartes's extended body (a mere object that is entirely distinct from the self) and Husserl's lived body (the flesh that is the self), the spread body is the organic body that I have, (...) that is not simply myself and yet is mine. This essay reveals the steep cost of phenomenology's neglect of the body, which produces a discarnation, or dissolution of the flesh itself. The "flesh without body" vanishes into transparency, exemplified by Descartes' "madmen" who lose all connection to their organic bodies, to the point of supposing that their bodies are glass. Because organicity is in fact proper to us, denying or rejecting its import can lead only to madness. (shrink)

In light of Jacques Derrida’s writings on death and mourning, it may seem that the Christian teaching that the dead will be raised is a betrayal of others, a failure to take up one’s responsibility to testify to those who have died. In conversation with Emmanuel Falque’s work on finitude, Martin Heidegger’s reading of 1 Thessalonians, and Søren Kierkegaard’s reading of Abraham, I respond in two movements to this objection to faith that God will raise the dead. First, I propose (...) that even for the Christian, the death of the other remains a loss, since the Christian must surrender the other to God. It is, however, this very surrender of the other to God that seems to be an abdication of responsibility. Second, therefore, I argue that faith in the resurrection decenters the self and challenges our understanding of responsibility even more than does Derrida’s own analysis. Faith, I conclude, means giving up the desire to cling to one’s own responsibility. (shrink)

Review of Johan de Jong, The Movement of Showing: Indirect Method, Critique, and Responsibility in Derrida, Hegel, and Heidegger (New York: SUNY, 2020).

Proper attention to the theme of corporeality is crucial for understanding Derrida’s analysis of Hegel in “The Pit and the Pyramid.” This article argues that Derrida’s essay compels us to face the impossibility of giving a wholly coherent account of embodiment. The _Aufhebung_ supposedly unites the exteriority of the corporeal with interiority in a higher unity that cancels and preserves them both; Hegel’s own text reveals, however, that meaning is primordially absent from the body that was thought to incarnate it. (...) And it is this absence of ideal meaning that is originary: Differance conditions the body as it conditions speech, rendering the body other than itself such that it is not categorizable as flesh that is the self or as an object that is not the self. I am and am not my body because the dichotomy between interiority and exteriority breaks down even at the level of the body. Indeed, I am and am not my self; the embodied self is disrupted from the start, never self-contained. Thus embodiment always already testifies to the other. (shrink)

While the traditional understanding of the look views it in terms of shame and oppression, I read Sartre’s Notebooks for an Ethics with Beauvoir’s Ethics of Ambiguity to argue that the look always gives me the world and inaugurates my freedom. Even the oppressor’s look reveals that I am free and that my existence is conditioned by the existence of other free beings. Because the look gives me the world as the arena within which I act freely, it is a (...) means of grace, and receiving it only in shame is bad faith. Although my existence remains unjustifiable and this grace cannot promise salvation, the look calls me out of shame to the pursuit of my and others’ freedom, and this call is a gift. (shrink)

My contributions to this book are the translations (French to English) of the Preface to the American Edition, "Opening: Confrontation with Étienne Gilson," and "Afterword: Saint Thomas and the Entrance of God into Philosophy.".

Through a study of nature and paternal power, this paper sheds light on the neglected theme of the relation between language and justice in Plato’s Cratylus. The dialogue inquires after the correctness of names, and it turns out that no lineage leads us back to a natural ground of names. Every lineage breaks; nature is always disrupted by the monstrous. It does not follow, however, that names are mere conventions without significance: on the contrary, naming is best understood as a (...) prayer to and for the just. The Cratylus reveals the insufficiency of language not to lead us to despair but to call us to the humility and the hope in which we must pray for justice. (shrink)

In the midst of a pandemic, what does it mean to see the Other as Other and not as a carrier of the virus? I argue that in seeking a Levinasian response to the pandemic, we must be mindful of the implications of the mechanisms of surveillance and control that, presented as ways to protect the Other, operate by controlling the Other and rendering our relation to the Other increasingly impersonal. Subjected to these mechanisms, the Other becomes a dangerous entity (...) that must be controlled, and the state that deploys them comes increasingly to mediate the relation between self and Other. The more we rely on such mechanisms for protection, the easier it becomes to regard the Other not as one who summons me to an infinite responsibility but as a vector of disease. Despite all the differences between Levinas’s and Foucault’s approaches, reading them in conversation shows that the control and surveillance of the population functions within a discourse that medicalizes and objectifies the Other in favor of the centralizing power that uses those technologies. In defiance of Levinas’s warning against imposing a narrative on the Other’s suffering, this discourse coopts that suffering as a justification for biopower. (shrink)

Drawing on Sartre's account of violence, I argue that not only is bad faith inevitable in practice, but a limited bad faith is necessary for authenticity. Although violating the freedom of others is bad faith, it is impossible to never violate anyone's freedom. Moreover, and more fundamentally, the ontological structure of the foritself entails that the for-itself can only be authentic in the mode of not being authentic. Seeking to altogether avoid bad faith is bad faith, for it is an (...) attempt to constitute oneself as essentially authentic, yet the for-itself has no preexisting essence. By recognizing one's complete responsibility for choosing bad faith, however, one limits one's bad faith. This limited bad faith is in fact necessary to authenticity, which is a project lived out in concrete situations and not a categorical moral law that forbids bad faith. (shrink)

Global ethics is no ordinary subject. It includes some of the most urgent and momentous issues the world faces, such as extreme poverty and climate change. Given this, any adequate review of that subject should, I suggest, ask some questions about the relation between what those working in that subject do and the real-world phenomena that are the object of their study. The main question I focus on in this essay is this: should academics and others working in the field (...) of global ethics take new measures aimed at having more real-world positive impact on the phenomena they study? Should they take new measures, that is, aimed at bringing about more improvements in those phenomena, improvements such as reductions in extreme poverty and in emissions of greenhouse gases? I defend a positive answer to this question against some objections, and also discuss some of the kinds of measure we might take in an attempt to have more positive impact. (shrink)

Arthur C. Danto proposes a complex and controversial relationship between surface and deep interpretations in The Philosophical Disenfranchisement of Art (1986). We detail the analogy between understanding human actions and interpreting works of art that both develops a motivation for Danto's view and clarifies it. We object to the most plausible version of content dependency among surface and deep interpretations and in so doing, we also clarify the way in which an interpretation is constitutive of an artwork.

In our paper "Surface and Deep Interpretation," we sought to provide detail and texture to Arthur Danto's views on interpretation, thereby explicating and defending them (as published in Mark Rollins, ed., Danto and His Critics (Blackwell, originally published 1993; second edition 2012). Leddy objects to our views; in the end, Danto's view, given our explication of it, remains tenable.

There has been a recent increase in interest in the place of race in the writings of modern canonical European philosophers (e.g., in Locke, Hume, Kant, and Hegel). However, while it is undoubtedly necessary to undertake such investigations, we should also not stop there, insofar as stopping there does not, in fact, overturn the charge of Eurocentrism or parochialism which has often been leveled against academic philosophy. Because the circle of interlocutors is not being expanded in such an approach, it (...) results in merely asking different questions about the same people (primarily male white European thinkers). Hence the importance of taking into consideration and critically evaluating the response of African philosophers and scientists such as James Africanus Beale Horton (1835 – 1883). (shrink)

In this review study, I reflect on Richard Horton’s book and his thesis that Western countries failed in their response to the current epidemic in the first half of 2020, with a few exceptions. In the five sections of the paper, after an initial modification of Horton’s thesis (A), I discuss briefly: the suppression approach in China (B), the mitigation approach in the West (C), the SARS epidemic as the key global public health event (D), the causes of (...) Western failure (epistemic, political, ethical, cultural, etc.) (E), and final envoi (F). (shrink)

Limited aggregationists argue that when deciding between competing claims to aid we are sometimes required and sometimes forbidden from aggregating weaker claims to outweigh stronger claims. Joe Horton presents a ‘fatal dilemma’ for these views. Views that land on the First Horn of his dilemma suggest that a previously losing group strengthened by fewer and weaker claims can be more choice-worthy than the previously winning group strengthened by more and stronger claims. Views that land on the Second Horn suggest (...) that combining two losing groups together and two winning groups together can turn the losing groups into the winning groups and the winning groups into the losing groups. This paper demonstrates that the ‘fatal dilemma’ is neither fatal nor a dilemma. The First Horn is devastating but avoidable and the Second Horn is unavoidable but not devastating. Nevertheless, Horton’s argument does help to narrow down the acceptable range of views. (shrink)

Joe Horton argues that partial aggregation yields unacceptable verdicts in cases with risk and multiple decisions. I begin by showing that Horton’s challenge does not depend on risk, since exactly similar arguments apply to riskless cases. The underlying conflict Horton exposes is between partial aggregation and certain principles of diachronic choice. I then provide two arguments against these diachronic principles: they conflict with intuitions about parity, prerogatives, and cyclical preferences, and they rely on an odd assumption about (...) diachronic choice. Finally, I offer an explanation, on behalf of partial aggregation, for why these diachronic principles fail. (shrink)

Myles Burnyeat maintains that Aristotelian epistêmê, in so far as it deals with explanations, is properly identified as understanding rather than as knowledge. Although Burnyeat is right in thinking that the cognitive achievement Aristotle typically has in mind is not justified true belief, Aristotelian epistêmê cannot be equated with understanding. On some occasions in Aristotle's writings (e.g. Apo 71a4), the term designates a particular science such as mathematics; on others (e.g. Apo 72b18-20), it designates the grasp of a first (...) principle; on others (e.g. Apo 94a20) it is a systematic grasp of fact and explanation that is properly termed understanding; and on still others (e.g. N. Ethics 1147a22) it is that combination of factual knowledge and competency in demonstration that qualifies as expertise or disciplinary mastery. (shrink)

Joe Horton’s all-or-nothing problem concerns a situation in which it is morally permissible to do nothing and to save two people but not to save only one. This description seems to entail that we should do nothing rather than save only one. I object to Horton’s solution and challenge a principle he draws attention to, which is required to generate the problem but which Horton regards as beyond dispute.

Supererogatory acts—good deeds “beyond the call of duty”—are a part of moral common sense, but conceptually puzzling. I propose a unified solution to three of the most infamous puzzles: the classic Paradox of Supererogation (if it’s so good, why isn’t it just obligatory?), Horton’s All or Nothing Problem, and Kamm’s Intransitivity Paradox. I conclude that supererogation makes sense if, and only if, the grounds of rightness are multi-dimensional and comparative.

Suppose two children face a deadly threat. You can either do nothing, save one child by sacrificing your arms, or save both by sacrificing your arms. Here are two plausible claims: first, it is permissible to do nothing; second, it is wrong to save only one. Joe Horton argues that the combination of these two claims has the implausible implication that if you are not going to save both children, you ought to save neither. This is one instance of (...) what he calls the ALL OR NOTHING PROBLEM. I here present CONDITIONAL PERMISSIONS as the solution. Although saving only one child is wrong, it can be conditionally permissible, that is, permissible given what you are not going to do. You ought to save both children or save neither, but if you are not going to save both, you ought to do the next best thing (save one) or save neither. (shrink)

Fetal reduction is the practice of reducing the number of fetuses in a multiple pregnancy, such as quadruplets, to a twin or singleton pregnancy. Use of assisted reproductive technologies increases the likelihood of multiple pregnancies, and many fetal reductions are done after in vitro fertilisation and embryo transfer, either because of social or health-related reasons. In this paper, I apply Joe Horton’s all or nothing problem to the ethics of fetal reduction in the case of a twin pregnancy. I (...) argue that in the case of a twin pregnancy, there are two intuitively plausible claims: abortion is morally permissible, and it is morally wrong to abort just one of the fetuses. But since we should choose morally permissible acts rather than impermissible ones, the two claims lead to another highly implausible claim: the woman ought to abort both fetuses rather than only one. Yet, this does not seem right. A plausible moral theory cannot advocate such a pro-death view. Or can it? I suggest ways to solve this problem and draw implications for each solution. There are no data in this work. (shrink)

Many philosophers are attracted to a complaints-based theory of the procreation asymmetry, according to which creating a person with a bad life is wrong (all else equal) because that person can complain about your act, whereas declining to create a person who would have a good life is not wrong (all else equal) because that person never exists and so cannot complain about your act. In this paper, I present two problems for such theories: the problem of impairable-life acceptance and (...) an especially acute version of the problem of improvable-life avoidance. I explain how these problems afflict two recent complaints-based theories of the procreation asymmetry, from Joe Horton and Abelard Podgorski. (shrink)

In the article, Twin pregnancy, fetal reduction and the ‘all or nothing problem’, I argued that there is a moral problem in multifetal pregnancy reduction from a twin to a singleton pregnancy. Drawing on Horton’s original version of the ‘all or nothing problem’, I argued that there are two intuitively plausible claims in 2-to-1 MFPR: aborting both fetuses is morally permissible, aborting only one of the twin fetuses is morally wrong. Yet, with the assumption that one should select permissible (...) choice over impermissible choice, the two claims lead to a counter-intuitive conclusion: the woman ought to abort both fetuses rather than only one. It would be odd to promote such a pro-death view. Begović _et al_ discuss my article and offer insightful criticism, claiming, that there is no ‘all or nothing problem’ present in 2-to-1 MFPR. In this short reply, I respond to some of their criticism. (shrink)

This paper is a test case for the claim, made famous by Myles Burnyeat, that the ancient Greeks did not recognize subjective truth or knowledge. After a brief discussion of the issue in Sextus Empiricus, I then turn to Plato's discussion of Protagorean views in the Theaetetus. In at least two passages, it seems that Plato attributes to Protagoras the view that our subjective experiences constitute truth and knowledge, without reference to any outside world of objects. I argue that (...) these passages have been misunderstood and that on the correct reading, they do not say anything about subjective knowledge. I then try out what I take to be the correct reading of the passages. The paper concludes with a brief discussion of the importance of causes in Greek epistemology. (shrink)

How could it be wrong to exploit—say, by paying sweatshop wages—if the exploited party benefits? How could it be wrong to do something gratuitously bad—like giving to a wasteful charity—if that is better than permissibly doing nothing? Joe Horton argues that these puzzles, known as the Exploitation Problem and All or Nothing Problem, have no unified answer. I propose one and pose a challenge for Horton’s take on the Exploitation Problem.

Dual-role approaches to reasons say, roughly, that reasons can relate to actions in two fundamentally different ways: they can either require conformity, or justify an action without requiring that it be taken. This paper develops a formal dual-role approach, combining ideas from defeasible logic and practical philosophy. It then uses the approach to shed light on the phenomenon of supererogation and resolve a well-known puzzle about supererogation, namely, Horton’s All or Nothing Problem.
