L'art occupe dans la pensée de Deleuze une place déterminante. De la littérature au cinéma, de la lettre à l'image, Deleuze théorise le domaine de l'art avec des concepts très nouveaux, attrayants et difficiles : corps sans organes, machines désirantes, devenir-animal, rhizome, lignes de fuite... Il s'agit ici d'en exposer le fonctionnement exact en montrant pourquoi l'art, selon Deleuze, devient une machine à explorer les devenirs des sociétés : critique et clinique, il détecte et rend sensibles les forces sociales. Mais (...) l'art produit surtout des effets réels, et non pas simplement imaginaires : l'image n'est donc pas une donnée mentale mais bien une réalité existante. Cet ouvrage se propose de faciliter l'accès à l'œuvre décisive de Deleuze, en restituant ses parcours dans un souci d'extrême clarté. (shrink)

Humanity stands at a precipice. -/- Our species could survive for millions of generations — enough time to end disease, poverty, and injustice; to reach new heights of flourishing. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, gaining the power to destroy ourselves, without the wisdom to ensure we won’t. Since then, these dangers have only multiplied, from climate change to engineered pandemics and unaligned artificial intelligence. If we do not (...) act fast to reach a place of safety, it may soon be too late. -/- The Precipice explores the science behind the risks we face. It puts them in the context of the greater story of humanity: showing how ending these risks is among the most pressing moral issues of our time. And it points the way forward, to the actions and strategies we can take today to safeguard humanity’s future. (shrink)

Think Like an Economist is a fun introduction to the main concepts of economics. It illustrates how the subject has a clear, practical purpose vital to our daily lives and thinking; includes stories of many of the world's greatest economists; and covers the history of economics from the early barter system through the Industrial Revolution to the emergence of globalization.

How should we make decisions when we're uncertain about what we ought, morally, to do? Decision-making in the face of fundamental moral uncertainty is underexplored terrain: MacAskill, Bykvist, and Ord argue that there are distinctive norms by which it is governed, and which depend on the nature of one's moral beliefs.

It is often said that there are three great traditions of normative ethics: consequentialism, deontology and virtue ethics. Each is based around a compelling intuition about the nature of ethics: that what is ultimately important is that we produce the best possible outcome, that ethics is a system of rules which govern our behaviour, and that ethics is about living a life that instantiates the virtues, such as honesty, compassion and loyalty. This essay is about how best to interpret consequentialism. (...) I show that if we take consequentialism beyond the assessment of acts, using a consequentialist criterion to assess decision making, motivation, and character, then the resulting theory can also capture many of the intuitions about systems of moral rules and excellences of character that lead people to deontology and virtue ethics. I begin by considering the argument that consequentialism is self-defeating because its adoption would produce bad outcomes. I take up the response offered by the classical utilitarians: when properly construed, consequentialism does not require us to make our decisions by a form of naïve calculation, or to be motivated purely by universal benevolence. Instead it requires us to use the decision procedure that will produce the best outcome and to have the motives that lead to the best outcome. I take this idea as my starting point, and spend the thesis developing it and considering its implications. I demonstrate that neither act-consequentialism nor rule-consequentialism has the resources to adequately assess decision making and motivation. I therefore turn to the idea of global consequentialism, which assesses everything in terms of its consequences. I then spend the greater part of the essay exploring how best to set up such a theory and how best to apply it to decision making and motivation. I overcome some important objections to the approach, and conclude by showing how the resulting approach to consequentialism helps to bridge the divide between the three traditions. (shrink)

This article focuses on the ethical implications of so-called ‘collateral damage’. It develops a moral typology of collateral harm to innocents, which occurs as a side effect of military or quasi-military action. Distinguishing between accidental and incidental collateral damage, it introduces four categories of such damage: negligent, oblivious, knowing and reckless collateral damage. Objecting mainstream versions of the doctrine of double effect, the article argues that in order for any collateral damage to be morally permissible, violent agents must comply with (...) high standards of care. In order for incidental harm to be permissible, an agent must take pains to avoid such harm even at higher cost to him- or herself. It is argued that accidentally but negligently caused collateral damage may be just as difficult to excuse as incidental harm. Only if high precautionary standards of care are met, can unintended harm to innocents – incidental or accidental – be permissible. In practice, such a strong commitment to avoiding harm to civilians may well lead us to question more generally and rethink more radically how violent conflicts ought to be fought, how military violence ought to be used and whether there are better ways of achieving those aims that we think are legitimate than those we are currently using.

This article explores the themes of trust and ethical conduct in social research, with particular attention to the trust that can develop between the members of a research team as well as between researchers and the researched. The authors draw upon a three-year empirical study of destinations and outcomes for young people excluded from alternative educational provision. They also make reference to a contemporary exposition of Aristotle's writing on friendship in order to explore two sets of relevant distinctions that have (...) a bearing upon our understanding of relationships that emerge in the context of social research projects. These distinctions are between impartiality and selectivity on the one hand, and between universality and particularity on the other. The authors attempt to demonstrate that these distinctions influence the development of trust and the conduct of ethical research, arguing that the latter is not synonymous with compliance to ethical guidelines.

The feminist philosopher and social scientist shows how "gendering" has affected the social and natural sciences as she reconciles the long-standing dichotomy between the quantitative and qualitative methods and demonstrates the tandem use of both experimental and intuitive approaches.

A fallibilist theory of knowledge is employed to make sense of the idea that agents know what they are doing 'without observation' (as on Anscombe's theory of practical knowledge).

WINNER BEST SOCIAL PHILOSOPHY BOOK IN 2021 / NASSP BOOK AWARD 2022 -/- Together we can often achieve things that are impossible to do on our own. We can prevent something bad from happening or we can produce something good, even if none of us could do it by herself. But when are we morally required to do something of moral importance together with others? This book develops an original theory of collective moral obligations. These are obligations that individual moral (...) agents hold jointly, but not as unified collective agents. To think of some of our obligations as joint or collective is the best way of making sense of our intuitions regarding collective moral action problems. Where we have reason to believe that our efforts are most efficient as part of a collective endeavor we may incur collective obligations together with others who are similarly placed as long as we are able to establish compossible individual contributory strategies towards that goal. The book concludes with a discussion of “massively shared obligations” to large-scale moral problems such as global poverty. (shrink)

Local opposition to infrastructure projects implementing renewable energy (RE) such as wind farms is often strong even if state-wide support for RE is strikingly high. The slogan “Not In My BackYard” (NIMBY) has become synonymous for this kind of protest. This paper revisits the question of what is wrong with NIMBYs about RE projects and how to best address them. I will argue that local opponents to wind farm (and other RE) developments do not necessarily fail to contribute their fair (...) share to producing a desirable public good (clean energy). In fact, with landscape concerns being at the heart of much protest, the question of fair burden distribution becomes sidelined: landscape impacts cannot be distributed nor compensated for. Protests may be attempts to express a true conflict of (incommensurable) values. Understanding them as such will help us better address NIMBY concerns and overcome such opposition through ensuring procedural justice. (shrink)

Over the last few decades, there has been an increasing interest in global consequentialism. Where act-consequentialism assesses acts in terms of their consequences, global consequentialism goes much further, assessing acts, rules, motives — and everything else — in terms of the relevant consequences. Compared to act-consequentialism it offers a number of advantages: it is more expressive, it is a simpler theory, and it captures some of the benefits of ruleconsequentialism without the corresponding drawbacks. In this paper, I explore the four (...) different approaches to global consequentialism made by Parfit, Pettit and Smith, Kagan, and Feldman. I break these up into their constituent components, demonstrating the space of possible global consequentialist theories, and I present two new theories within this space. (shrink)

The standard view of ignorance is that it consists in the mere lack of knowledge or true belief. Duncan Pritchard has recently argued, against the standard view, that ignorance is the lack of knowledge/true belief that is due to an improper inquiry. I shall call, Pritchard’s alternative account the Normative Account. The purpose of this article is to strengthen the Normative Account by providing an independent vargument supporting it.

It is often claimed that from the moment of conception embryos have the same moral status as adult humans. This claim plays a central role in many arguments against abortion, in vitro fertilization, and stem cell research. In what follows, I show that this claim leads directly to an unexpected and unwelcome conclusion: that natural embryo loss is one of the greatest problems of our time and that we must do almost everything in our power to prevent it. I examine (...) the responses available to those who hold that embryos have full moral status and conclude that they cannot avoid the force of this argument without giving up this key claim.

Une morale pour les mortels est une etude d'ensemble de l'ethique de Platon et d'Aristote, a partir de la problematique philosophique qui lui donne corps: la mortalite de l'etre humain, source de ses desirs et de leur perpetuelle insatisfaction.

A partir de cette problematique sont repris (...) et eclaires tous les concepts et theses classiques de l'ethique ancienne: la question de la mesure et de l'harmonie, la vertu dans son unite et sa pluralite, le bonheur, le bien, le plaisir, l'amitie, l'amour de soi, la volonte et les autres desirs, l'intention, l'action, et surtout la verite du paradoxe nul n'est mechant de plein gre, dont sont exposees la resistance face aux critiques d'Aristote et les consequences dans le domaine penal.

Two experiments were run to demonstrate the presence of a partial reinforcement extinction effect (PREE) and a partial punishment effect (PPE) 4 weeks after training in a 1-trial/day procedure. In the PREE paradigm, two groups of animals were trained to run a straight alley for food reward; one group was rewarded on every trial (CRF), whereas the other was rewarded on only 50% of the trials (PRF). In the test phase, extinction, no reward was present on any trial. Four weeks (...) after the end of acquisition, and subsequent to 7 days of CRF retraining, PRF animals showed greater resistance to extinction than did their CRF controls. The PPE paradigm resembled the PREE paradigm in all aspects, except that mild electric foot shock, together with the food reward, was used instead of nonreward on 50% of the acquisition trials. In the test phase, all animals were shocked and given a food reward on every trial. Four weeks after the end of acquisition and retraining, the animals with previous experience of shock in acquisition showed greater resistance to punishment than did their controls. (shrink)

What is it that makes us as citizens liable for the actions – including the wrongdoings – of our state? Answering this question is part of the larger debate on the nature of complicity and collective action. When are we connected to joint endeavours and collective outcomes in a way that makes us (on some level) responsible for them? -/- Of particular interest within this debate is the normative relationship of citizens to their state. For instance, when states pay reparations (...) for past crimes the costs are – one way or another – borne by their citizens. In Responsible Citizens, Irresponsible States (OUP 2021), Avia Pasternak examines with admirable clarity and circumspection if states are justified in imposing the cost of their past wrongdoings on all of their citizens, including those who played no obvious part in those crimes.

Together we can achieve things that we could never do on our own. In fact, there are sheer endless opportunities for producing morally desirable outcomes together with others. Unsurprisingly, scholars have been finding the idea of collective moral obligations intriguing. Yet, there is little agreement among scholars on the nature of such obligations and on the extent to which their existence might force us to adjust existing theories of moral obligation. What interests me in this paper is the perspective of (...) the moral deliberating agent who faces a collective action problem, i.e. the type of reasoning she employs when deciding how to act. I hope to show that agents have collective obligations precisely when they are required to employ ‘we-reasoning’, a type of reasoning that differs from I-mode, best response reasoning, as I shall explain below. More precisely, two (or more) individual agents have a collective moral obligation to do x if x is an option for action that is only collectively available (more on that later) and each has sufficient reason to rank x highest out of the options available to them.

Die vorliegende Schrift unternimmt eine Revision des vorherrschenden Bildes der Rolle und der Konzeptionen von Moral und Ethik im Wiener Kreis. Dieses Bild wird als zu einseitig und undifferenziert zurückgewiesen. Die Ansicht, die Mitglieder des Wiener Kreises hätten kein Interesse an Moral und Ethik gezeigt, wird widerlegt. Viele Mitglieder waren nicht nur moralisch und politisch interessiert, sondern auch engagiert. Des Weiteren vertraten nicht alle die Standardauffassung logisch-empiristischer Ethik, die neben der Anerkennung deskriptiv-empirischer Untersuchungen durch die Ablehnung jeglicher normativer und inhaltlicher (...) Ethik und der Verfechtung eines extremen Nonkognitivismus geprägt ist. Am meisten entspricht die Standardauffassung den Ansichten Rudolf Carnaps, weniger bereits jenen Karl Mengers, Otto Neuraths oder Philipp Franks. Am weitesten weichen Moritz Schlick, Victor Kraft sowie Herbert Feigl von der Standardauffassung ab. Entgegen dem herkömmlichen Bild weltabgewandter Logiker und Metaethiker wurde im Wiener Kreis sogar Angewandte Ethik betrieben, und dies bereits unter diesem Namen. Neben den ethischen Hauptthemen und Ansichten der jeweiligen Philosophen in ihrer Entwicklung im Rahmen ihres persönlichen und kulturellen Kontextes zeigt die Untersuchung, dass allen Ansätzen eine aufgeklärte und humanistische Version von Moral und Ethik gemeinsam ist. Dieser wissenschaftliche Humanismus, der sich schon in der Programmschrift Wissenschaftliche Weltauffassung. Der Wiener Kreis findet, liegt jedoch in verschiedenen Ausprägungen vor. Was die Abweichungen von der Standardauffassung wesentlich betrifft, ist ihre unterschiedliche Auffassung von Moral als gemeinsames oder individuelles Unternehmen. Carnap führt ein extremer Individualismus zu einem extremen Nonkognitivismus, in dem ihm Menger folgt. Bei Schlick ist die Lage zweideutig, was sich in unterschiedlichen Moralbegriffen widerspiegelt. Bei Kraft und Feigl tritt das Verständnis von Moral als gemeinschaftlich geteilte Praxisform klar hervor. Auf der Basis eines gemeinsamen Begriffs des moralisch Guten, der auch eine Sachkomponente enthält, ist eine Verständigung über moralische Fragen möglich. Von einem extremen Nonkognitivismus kann dort nicht mehr die Rede sein. Mit diesen Ergebnissen verbietet es sich, dem Wiener Kreis allgemein eine Ablehnung normativer Ethik und einen extremen Nonkognitivismus zuzuschreiben. Eine systematische Ethik, die Moral als Gemeinschaftspraxis begreift, steht einigen im Wiener Kreis näher, als das vorherrschende Bild suggerieren möge. Wer meint, mit engem Bezug zur Tradition des Wiener Kreises nur Carnap folgen zu können und Ethik als suspektes Unternehmen betrachten zu müssen, irrt. Ethik war in der Tradition Analytischer Philosophie nicht immer so marginalisiert, wie sie es in manchen ihrer Teilrichtungen heute noch ist und Gegner(innen) der Analytischen Philosophie vorwerfen. Die vorliegende Untersuchung liefert die nötige Revision einer verfänglichen Fehlentwicklung. (shrink)

Humans are prone to producing morally suboptimal and even disastrous outcomes out of ignorance. Ignorance is generally thought to excuse agents from wrongdoing, but little attention has been paid to group-based ignorance as the reason for some of our collective failings. I distinguish between different types of first-order and higher order group-based ignorance and examine how these can variously lead to problematic inaction. I will make two suggestions regarding our epistemic obligations vis-a-vis collective (in)action problems: (1) that our epistemic obligations (...) concern not just our own knowledge and beliefs but those of others, too and (2) that our epistemic obligations can be held collectively where the epistemic tasks cannot be performed by individuals acting in isolation, for example, when we are required to produce joint epistemic goods.

Many philosophers have defended the view that we are subject to the following evidential ought: “One ought to believe in accordance with one's evidence.” Although they agree on this, a more fundamental question keeps dividing them: from where does the evidential ought derive its normative force? The instrinsicalist answer to this question is sometimes described as the claim that "there is a brute epistemic value in believing in accordance with one's evidence" (Cowie, 2014, 4005). But what does this really mean? (...) Intrinsicalists' negative claim is that the normative source of the evidential ought has nothing to do with the fulfilment of our epistemic purposes. But what is their positive claim exactly? This paper aims at improving our understanding of intrinsicalism. Its conclusion is that there is only one possible way of being an intrinsicalist. Intrinsicalists need to be constitutivists. (shrink)

It is often argued that our obligations to address structural injustice are collective in character. But what exactly does it mean for ‘ordinary citizens’ to have collective obligations visà- vis large-scale injustice? In this paper, I propose to pay closer attention to the different kinds of collective action needed in addressing some of these structural injustices and the extent to which these are available to large, unorganised groups of people. I argue that large, dispersed and unorganised groups of people are (...) often in a position to perform distributive collective actions. As such, ordinary citizens can have massively shared obligations to address structural injustice through distributive action, but, ultimately, such obligations are ‘collective’ only in a fairly weak sense.

In early China, was it correct for a woman to disobey her father, contradict her husband, or shape the public policy of a son who ruled over a dynasty or state? According to the _Lienü zhuan_, or_ Categorized Biographies of Women_, it was not only appropriate but necessary for women to step in with wise counsel when fathers, husbands, or rulers strayed from the path of virtue. Compiled toward the end of the Former Han dynasty (202 BCE-9 CE) by Liu (...) Xiang (79-8 BCE), the _Lienü zhuan_ is the earliest extant book in the Chinese tradition solely devoted to the education of women. Far from providing a unified vision of women's roles, the text promotes a diverse and sometimes contradictory range of practices. At one extreme are exemplars resorting to suicide and self-mutilation as a means to preserve chastity and ritual orthodoxy. At the other are bold and outspoken women whose rhetorical mastery helps correct erring rulers, sons, and husbands. The text provides a fascinating overview of the representation of women's roles in early legends, formal speeches on statecraft, and highly fictionalized historical accounts during this foundational period of Chinese history. Over time, the biographies of women became a regular feature of dynastic and local histories and a vehicle for expressing and transmitting concerns about women's social, political, and domestic roles. The _Lienü zhuan_ is also rich in information about the daily life, rituals, and domestic concerns of early China. Inspired by its accounts, artists across the millennia have depicted its stories on screens, paintings, lacquer ware, murals, and stone relief sculpture, extending its reach to literate and illiterate audiences alike.

How should we make choices when we know so little about our futures? L. A. Paul argues that we must view life decisions as choices to make discoveries about the nature of experience. Her account of transformative experience holds that part of the value of living authentically is to experience our lives and preferences in whatever ways they evolve.

This paper argues in favor of a particular account of decision‐making under normative uncertainty: that, when it is possible to do so, one should maximize expected choice‐worthiness. Though this position has been often suggested in the literature and is often taken to be the ‘default’ view, it has so far received little in the way of positive argument in its favor. After dealing with some preliminaries and giving the basic motivation for taking normative uncertainty into account in our decision‐making, we (...) consider and provide new arguments against two rival accounts that have been offered—the accounts that we call ‘My Favorite Theory’ and ‘My Favorite Option’. We then give a novel argument for comparativism—the view that, under normative uncertainty, one should take into account both probabilities of different theories and magnitudes of choice‐worthiness. Finally, we further argue in favor of maximizing expected choice‐worthiness and consider and respond to five objections. (shrink)

The challenges facing us today require practical wisdom to allow us to react appropriately. In this paper, we argue that at a group level, we will make better decisions if we respect and take into account the moral judgment of agents with diverse styles of cognition and moral reasoning. We show this by focusing on the example of autism, highlighting different strengths and weaknesses of moral reasoning found in autistic and non-autistic persons respectively.

In lieu of an abstract, here is a brief excerpt of the content:Wild LoveCynthia Willett’s Biosocial Eros EthicsAnn V. MurphyI’ll frame my comments in honor of Cynthia Willett’s work in light of two recent anecdotes:Anecdote I: It happened that one evening as I was reading Willett’s most recent monograph Interspecies Ethics—in particular the chapter on animals’ capacity for laughter and humor—my wonderful (if somewhat insubordinate) Airedale terrier, Nora Mae Murphy, heard me laughing, trotted into the living room, jumped on the (...) couch, looked at me with concern, stared down at the book in my hand, then placed her paw on my arm as if to check my pulse, eyes wide and ears slicked back. Nora is used to me reading philosophy at night; but she is not used to me laughing loudly while doing so. Clearly, she was curious. I smiled in recognition of what Nora’s behavior had enabled me to realize: I don’t often laugh when I read philosophy, not like I did that night while reading Willett’s work.Anecdote II: Cindy came out to New Mexico last spring to give the keynote address at our department’s annual graduate student conference. The afternoon she arrived, a few graduate students had arranged to take her on a hike in a nature preserve, a beautiful tract of land alongside the Rio Grande, which winds through Albuquerque. The next day, two of [End Page 50] the graduate students were in my office and I asked how the hike went. The students looked at each other, shuffled a bit, and stared at the floor until one announced, “Well, we kind of got locked in the preserve.” Me: “You got locked in the nature preserve?” “Yep, but it all worked out okay. She was cool with it,” one student reported. The other added: “Yeah, she’s pretty wild.”That conversation happened months before I was asked to speak on and to Willett’s work, but that conversation, that compliment, that word—“wild”—came to mind many times as I was preparing these comments in her honor. And I mean “wild” in the best sense: as rowdy and irreverent and joyful. There is a wildness to Willett’s texts in their performative aspect, one that marks them as singular. Bucking certain philosophical tendencies to overindulge a metaphorics of war and violence, Willett’s own work evinces an entirely different philosophical orientation, one that takes love, and more specifically eros, as its bedrock. The wildness of Willett’s ethical philosophy comes into play in the truly variable scenes in which Willett locates eros and its promise. It’s a wild kind of love that informs Willett’s ethics, one that refuses domestication, refuses to be hemmed in by the borders between species, refuses to be fixed. The scope that Willett assigns eros is broad, countering the tendency to reduce it to the sexualized and sentimental contexts in which it is often placed.1At the heart of Willett’s deliberations across her four monographs and many articles is an abiding concern with, and celebration of, eros as a site of social, political, and ethical promise. A preoccupation with eros is evident in her work from the very beginning. In her first monograph, Maternal Ethics and Other Slave Moralities (1995), Willett frames her project in reference to Audre Lorde’s claim (in Lorde’s essay “Uses of the Erotic: The Erotic as Power”) that European American culture has perpetuated an understanding of power that parses the erotic from the spiritual and political and as a consequence has “suppressed the deepest source of power and knowledge in our lives” (Lorde 1984, 55, cited in Willett 1995, 7). This first book suggests new conceptions of freedom and ethical subjectivity based on social eroticism, a project furthered in her second monograph The Soul of Justice: Social Bonds and Racial Hubris (2001), where hubris is understood with and against the Greeks as an assault on this primary sociality. “In response to the Greeks we might say that the person is born, not of honor, but of love. Sociality, or social eros, and not honor is the origin and the goal of the person and the positive core of freedom... (shrink)

Environmental ethicists have been arguing for decades that swift action to protect our natural environment is morally paramount, and that our concern for the environment should go beyond its importance for human welfare. It might be thought that the widespread acceptance of moral anti-realism would undermine the aims of environmental ethicists. One reason is that recent empirical studies purport to show that moral realists are more likely to act on the basis of their ethical convictions than anti-realists. In addition, it (...) is sometimes argued that only moral realists can countenance the claim that nature is intrinsically valuable. Against this, we argue that the acceptance of moral anti-realism is no threat to the environmentalist cause. We argue, further, that the acceptance of moral realism is potentially an obstacle to delivering on a third core environmental ethicist demand: namely, that successful action on climate change and environmental destruction requires us to change some of our commonly-held ethical views and to achieve a workable consensus.

Duties to reduce global poverty are often portrayed as collective duties to assist. At first glance this seems to make sense: since global poverty is a problem that can only be solved by a joint effort, the duty to do so should be considered a collective duty. But what exactly is meant by a ‚joint‘ or ‚collective‘ duty? This paper introduces a distinction between genuinely cooperative and cumulative collective actions. Genuinely cooperative actions require mutually responsive, carefully adjusted contributory actions by (...) cooperating agents, while contributions to cumulative actions are largely independent. The global affluent’s obligation to combat global poverty is not an obligation to perform a genuinely cooperative action. Instead, for most of us the morally best response is to contribute to existing cumulative endeavours. Our obligation to donate money to suitable organisations is a duty to contribute to cumulative action. Collective actions can produce fixed-sum or incremental goods. A collective obligation to produce a fixed-sum good is not distributive, that is, it is an obligation of the plurality of agents as such. This applies to obligations requiring both genuinely cooperative and cumulative actions. I call these kinds of obligations strongly collective obligations. However, for incremental goods the implications are less clear. There, the parameters for moral compliance are not dictated by problem for remedy as such. Rather, the magnitude of the required good is the sum of individually adequate contributions. What is collectively required depends on what is individually required. I propose to call these kinds of obligations weakly collective obligations. It turns out that we – the affluent – have a collective obligation to combat global poverty only in the weak sense. The obligation is collective in the sense that there is joint necessity and that we must contribute to a collective endeavour. Our donations are intended as contributions to a shared goal. But our duty to combat poverty is not a collective duty in the non-distributive, strong sense. This means that we need not necessarily take up the slack left by others or else stop contributing when others do more than their fair share. (shrink)

Prioritarianism is the moral view that a fixed improvement in someone's well-being matters more the worse off they are. Its supporters argue that it best captures our intuitions about unequal distributions of well-being. I show that prioritarianism sometimes recommends acts that will make things more unequal while simultaneously lowering the total well-being and making things worse for everyone ex ante. Intuitively, there is little to recommend such acts and I take this to be a serious counterexample for prioritarianism.

In this report I provide an introduction to the burgeoning field of hypercomputation – the study of machines that can compute more than Turing machines. I take an extensive survey of many of the key concepts in the field, tying together the disparate ideas and presenting them in a structure which allows comparisons of the many approaches and results. To this I add several new results and draw out some interesting consequences of hypercomputation for several different disciplines.

If people have different resources, tastes, or needs, they may be able to exchange goods or services such that they each feel they have been made better off. This is trade. If people have different moral views, then there is another type of trade that is possible: they can exchange goods or services such that both parties feel that the world is a better place or that their moral obligations are better satisfied. We can call this moral trade. I introduce (...) the idea of moral trade and explore several important theoretical and practical implications. (shrink)
