There are a number of cases where, collectively, groups cause harm, and yet no single individual’s contribution to the collective makes any difference to the amount of harm that is caused. For instance, though human activity is collectively causing climate change, my individual greenhouse gas emissions are neither necessary nor sufficient for any harm that results from climate change. Some (e.g., Sinnott-Armstrong) take this to indicate that there is no individual moral obligation to reduce emissions. There is a collective action (...) problem here, to which I offer a solution. My solution rests on an argument for a (sometimes) bare moral difference between intending harm and foreseeing with near certainty that harm will result as an unintended side-effect of one’s action. I conclude that we have a moral obligation to reduce our individual emissions; and, more broadly, an obligation to not participate in many other harmful group activities (e.g., factory-farming).

The concept of well-being is increasingly gaining acceptance as an object of science, and many different types of well-being measures have been developed. A debate has emerged about which measures are able to capture well-being successfully. An important underlying problem is that there is no unified conceptual framework about the nature of well-being—a hotly debated topic of philosophical discussion. I argue that while there is little agreement about the nature of well-being in philosophy, there is an important agreement on some (...) important principles relevant for its measurement. I argue that well-being science has good reasons to accommodate these principles, but currently fails to do so. (shrink)

This essay surveys the main objections to aesthetic hedonism, the view that aesthetic value is reducible to the value of aesthetic pleasure or experience. Hedonism is the dominant view of aesthetic value, but a spate of recent criticisms has drawn its accuracy into question. I introduce some distinctions crucial to the criticisms, before using the bulk of the essay to identify and review six major lines of argument that hedonism's critics have employed against it. Whether or not these arguments suffice (...) to refute hedonism decisively, I argue that its privileged status, as the sole contender in aesthetic value theory, is detrimental to downstream research on aesthetic phenomena. The essay concludes with an overview of current work and promising avenues of inquiry into non-hedonic alternatives. (shrink)

In this article, I argue that the state has a prima facie obligation to help its citizens satisfy their autonomous preferences. I argue that this obligation is grounded in the state's obligation to respect its citizens as persons, and that part of what is involved in respecting someone as a person is helping her satisfy her autonomous preferences. I argue that that which makes preferences autonomous is also that which makes them, and not their non-autonomous counterparts, worthy of respect. In (...) addition, I reject other views of what makes preferences worthy of respect, in particular Ronald Dworkin's view that only preferences for one's own enjoyment of some goods or opportunities deserve political consideration. Finally, I consider the state's obligation towards immoral autonomous preferences, and I argue that the state's prima facie obligation to promote the satisfaction of autonomous preferences is quite strong.

En este trabajo respondo una objeción a la tesis de que la teoría de Rawls debe atender problemas relacionados a la injusticia histórica. Esta objeción sostiene que dicha teoría está justificada en no considerar problemas de injusticia histórica debido a su supuesto carácter exclusivamente prospectivo. La objeción tiene dos presentaciones diferentes. Primero, como la idea de que hay razones internas a la propia teoría de Rawls que justifican dicho carácter exclusivamente prospectivo —tales como el problema de elección modelado en la (...) posición original y el hecho de que la justicia-como-equidad debe ser una concepción de justicia no-comprehensiva. Segundo, como la idea de que hay razones externas a la teoría de Rawls —en concreto, la supuesta existencia del así llamado problema de la no-identidad, que justifican el carácter exclusivamente prospectivo no sólo de los principios de justicia rawlsianos sino de cualquier otra concepción de justicia distributiva. Trataré de mostrar que esta objeción, tanto en su presentación interna como externa, es equivocada. (shrink)

This article is a plea for a realist view of deliberative bodies against a nominalist view. They cannot be reduced to the changing collection of the individuals who compose it. The deliberative bodies are real collective entities insofar as we are able to precise their criteria of identity. These are the differentiation between an interior and an exterior linked by functions or ends; thus these collective entities are adaptive systems. There are three kinds of such adaptive systems: technical systems, organisms (...) and human organizations. The specificity of human organizations is related to the nature of the relations between parties, which are normative, and to the way their ends are determined. Deliberative bodies are organizations of which the specific characteristics have been listed. The mode of being of these collective entities is adverbial. This means that the existence of a deliberative body is subordinated to the nature of the activity of its members and to the manner they are oriented toward its instituted ends. (shrink)

Our fundamental conception of the self seems to be, broadly speaking, epistemic: selves are things that have thoughts, undergo experiences, and possess reasons for action and belief. In this paper, I evaluate the consequences of this epistemic conception for the widespread view that properties like thinking that arthritis is painful are relational features of the self.

The paper argues that the idea of gift-giving and its associated imagery, which has been founding the ethics of organ transplants since the time of the first successful transplants, should be abandoned because it cannot effectively block arguments for markets in human body parts. The imagery suggests that human bodies or their parts are transferable objects which belong to individuals. Such imagery is, however, neither a self-evident nor anthropologically unproblematic construal of the relation between a human being and their body. (...) The paper proposes an alternative conceptualization of that relation, the identity view according to which a human being is identical with their living body. This view, which offers a new ethical perspective on some central concepts of transplant medicine and its ethical and legal standards and institutions, supports widely shared intuitive ethical judgments. On this proposal, an act of selling a human body or one of its parts is an act of trade in human beings, not in owned objects. Transfers of human body parts for treatment purposes are to be seen as sharing in another human being’s misfortune rather than as giving owned objects. From the perspective of policy-making, the proposal requires, first, that informed consent for removal of transplant material be obtained from the potential benefactor. Secondly, explicit consent by the prospective benefactor is obligatory in the case of removal of transplant material from a living benefactor. Thirdly, in the case of posthumous retrieval, informed consent by the potential benefactor during their life is not ethically indispensable. Additionally, while refusal of posthumous retrieval expressed by a potential benefactor during their life must be respected, such a refusal needs ethical justification and explanation. (shrink)

Andrei Tarkovsky's film Solaris is studied through the lens of philosophy of mind. The question of memory and personhood, as developed by John Locke and then expanded by Derek Parfit, is applied to the status of Hari – the copy of the protagonist's deceased wife. The key question addressed by this paper is on what basis Hari can be considered human. Hari's personhood is further analyzed in the context of Cartesian dualism, the response to Descartes by reductionism and the rebuttal (...) of reductionism by the functionalist theories of Hilary Putnam. Descartes' thoughts on animal suffering and the bête-machine are pitted against Hari's experience in Solaris. The key question is whether Hari can be reduced to her alien structure or should be considered in terms of her behavior. The moral implications of these questions are extended to human sociality, human emotional response and the role of the body in the human condition. (shrink)

Journal of Political Philosophy, EarlyView.

In April 2019, Greta Thunberg made TIME Magazine’s 100 Most Influential People of 2019 list. The 16 year-old climate activist, who has also been nominated for a Nobel Peace Prize, started a movement that saw a multitude of student protests and school strikes around the world centred on action against climate change. TIME Magazine quoted her saying, “We can’t save the world by playing by the rules, because the rules have to be changed.” With her engagement, Thunberg inspired thousands of (...) youth activists to join her in her efforts and has thus put not only climate change on the political agenda but also the political participation and representation of the young. And this even though Thunberg and many of her fellow protesters do not yet enjoy voting rights in their respective countries. Just like the previous issue of the Intergenerational Justice Review, this one is also dedicated to the topic of the underrepresentation of younger people in political decision-making. The first two contributions in this issue pay particular attention to the existence – or lack thereof – of networks and contacts in politics that seem to be important for political representation. Daniel Stockemer and Aksel Sundström’s article titled “Youth’s underrepresentation in the European Parliament: Insights from interviews with young Members of the European Parliament ” reports results from qualitative interviews with 23 MEPs on the factors contributing to the success and failure of young people to enter the European Parliament. They find that, in general, three common themes or complaints amongst the successful young MEPs, irrespective of their party affiliation: “ a general reluctance within parties to nominate young candidates, young candidates lacking the necessary contacts in parties to get elected, and young candidates having too little experience to gain nomination for an electable seat.” Despite these heavy criticisms of established politicians and structures, the authors also summarise some more hopeful suggestions by respondents centring around the role of party youth organisations. The second contribution, by Emilien Paulis, also highlights the important role of networks and contacts, yet already at an earlier stage: when joining a political party. Drawing on social network and political participation theory and novel survey data from Belgium, Paulis explores what network patterns contribute to young people’s enrolment in a political party. He discovers strong social ties between young party members and suggests that this indicates “a certain exclusivity in recruitment patterns of political parties”. In addition, his analysis also points out that a highly homogenous network composition is a statistically significant predictor of joining a political party. Overall, Paulis, similar to Stockemer and Sundström, suggests a review of institutional processes and structures within established political organisations such as parties in order to promote a more diverse and above all younger profile of politically active citizens. The final contribution in this issue offers insights from an online survey conducted among young adults in Germany suggesting that these respondents were indeed politically interested and felt willing to assume responsibility through participation. As a consequence, Philipp Köbe concludes from his analysis that the supply-side of political organisations is the main problem in the underrepresentation and not so much young people’s lack of engagement. His four specific recommendations to political organisations follow very much from this conclusion: providing transparent and suitable information to meet young people’s interests and demands; lowering the electoral threshold for parties’ parliamentary representation to improve the representation of minority opinions; expanding youth-friendly opportunities for political participation such as video conferences and social media usages in order to reach out to the appropriate groups; improving the efficiency and impact of political decision-making to reward political engagement amongst young people. Köbe finally suggests a steering instrument for political organisations to help them achieve these goals. In the book review section, we continue the theme of political participation and representation of the young. Simon Pistor reviews the book Youthquake 2017: The Rise of Young Cosmopolitans in Britain by James Sloam and Matt Henn. The book investigates youth political participation in Britain around and after the Brexit referendum in 2016 and is built around the new notion a “youthquake” – a term initially introduced by British media to describe the surprising success of the movement behind the Labour Party but later on also becoming Oxford Dictionaries’ 2017 word of the year. Pistor writes that Sloam and Henn expand the concept of a youthquake in their book to “youthquake elections” – “ones in which dramatic changes in how many young people vote, who they vote for and how active they are in the campaign have, quite literally, shaken up the status quo”. Using this concept, the book’s central claim is that it was a youth movement based on a broader appeal to the needs of young people which spiked the higher voter turnout among young people. Pistor’s review of the book is unequivocal: using methods from comparative politics, the authors provide a “very interesting argument” and “a clear empirical case for the youthquake during the 2017 General Election in the UK”. Pistor also welcomes especially two implications of the book: many young British people are not as politically disenfranchised as general wisdom holds ; many of them are not only cosmopolitans but also British cosmopolitans interested and engaged in national politics. Overall, Simon Pistor concludes that Sloam and Henn’s book is “an empirically rich and informed study”, which might suggest that the key to future democratic successes does indeed lie with the young.

Derek Parfit has famously pointed out that ‘total’ utilitarian views, such as classical hedonistic utilitarianism, lead to the conclusion that, to each population of quite happy persons there corresponds a more extensive population with people living lives just worth living, which is better. In particular, for any possible population of at least ten billion people, all with a very high quality of life, there must be some much larger imaginable population whose existence, if other things are equal, would be better, (...) even though its members have lives that are barely worth living. This world is better if the sum total of well-being is great enough, and it is great enough if only enough sentient beings inhabit it. This conclusion has been considered by Parfit and others to be ‘repugnant’. (shrink)

Phineas Gage’s story is typically offered as a paradigm example supporting the view that part of what matters for personal identity is a certain magnitude of similarity between earlier and later individuals. Yet, reconsidering a slight variant of Phineas Gage’s story indicates that it is not just magnitude of similarity, but also the direction of change that affects personal identity judgments; in some cases, changes for the worse are more seen as identity-severing than changes for the better of comparable magnitude. (...) Ironically, thinking carefully about Phineas Gage’s story tells against the thesis it is typically taken to support. (shrink)

The personal identity relation is of great interest to philosophers, who often consider fictional scenarios to test what features seem to make persons persist through time. But often real examples of neuroscientific interest also provide important tests of personal identity. One such example is the case of Phineas Gage – or at least the story often told about Phineas Gage. Many cite Gage’s story as example of severed personal identity; Phineas underwent such a tremendous change that Gage “survived as a (...) different man.” I discuss a recent empirical finding about judgments about this hypothetical. It is not just the magnitude of the change that affects identity judgment; it is also the negative direction of the change. I present an experiment suggesting that direction of change also affects neuroethical judgments. I conclude we should consider carefully the way in which improvements and deteriorations affect attributions of personal identity. This is particularly important since a number of the most crucial neuroethical decisions involve varieties of cognitive enhancements or deteriorations. (shrink)

When assessing the cost effectiveness of health care programmes, health economists typically presume that distant events should be given less weight than present events. This article examines the moral reasonableness of arguments advanced for positive discounting in cost-effectiveness analysis both from an intergenerational and an intrapersonal perspective and assesses if arguments are equally applicable to health and monetary outcomes. The article concludes that behavioral effects related to time preferences give little or no reason for why society at large should favour (...) the present over the future when making intergenerational choices regarding health. The strongest argument for discounting stems from the combined argument of diminishing marginal utility in the presence of growth. However, this hinges on the assumption of actual growth in the relevant good. Moreover, current modern democracy may be insufficiently sensitive to the concerns of future generations. The second part of the article categorises preference failures (which justify paternalistic responses) into two distinct groups, myopic and acratic. The existence of these types of preference failures makes elicited time preferences of little normative relevance when making decisions regarding the social discount rate, even in an intrapersonal context. As with intergenerational discounting, the combined arguments of growth and diminishing marginal utility offer the strongest arguments for discounting in the intrapersonal context. However, there is no prima facie reason to assume that this argument should apply equally to health and monetary values. To be sure, selecting an approach towards discounting health is a complex matter. However, the life-or-death implications of any approach require that the discussion not be downplayed to merely a technical matter for economists to settle. (shrink)

Total utilitarianism implies Parfit's repugnant conclusion. For any world containing ten billion very happy people, there is a better world where a vast number of people have lives barely worth living. One common response is to claim that life in Parfit's Z is better than he suggests, and thus that his conclusion is not repugnant. This paper shows that this strategy cannot succeeed. Total utilitarianism also implies a reverse repugnant conclusion. For any world where ten billion people have lives of (...) excruciating agony, there is a worse world where a vast number of people have lives almost worth living. This reverse repugnant conclusion is at least as repugnant as Parfit's original. If we avoid the latter by raising the zero level, then the former becomes more repugnant. We cannot save total utilitarianism by tinkering with the zero level. (shrink)

Perhaps death’s badness is an illusion. Epicureans think so and argue that agents cannot be harmed by death when they’re alive nor when they’re dead. I argue that each version of Epicureanism faces a fatal dilemma: it is either committed to a demonstrably false view about the relationship between self-regarding reasons and well-being or it is involved in a merely verbal dispute with deprivationism. I first provide principled reason to think that any viable view about the badness of death must (...) allow that agents have self-regarding reason to avoid death if doing so would increase their total well-being. I then show that Epicurean views which do not preserve this link are subject to reductio arguments and so should be rejected. After that, I show that the Epicurean views which accommodate this desideratum are involved in a merely verbal dispute with deprivationism. (shrink)

In this paper I argue that the debate between subjective and objective theories of prudential value obscures the way in which elements of both are needed for a comprehensive theory of prudential value. I suggest that we characterize these two types of theory in terms of their different aims: procedural (or subjective) theories give an account of the necessary conditions for something to count as good for a person, while substantive (or objective) theories give an account of what is good (...) for a person, given some set of necessary conditions. Characterizing the theories in this way allows us to see their mutual compatibility. To make this case, I assume that a theory of prudential value ought to be descriptively and normatively adequate. The criterion of descriptive adequacy requires that our theory explain the subject relativity of prudential value. I characterize subject relativity in terms of justifiability to subjects and I argue that certain procedural theories are well suited to meet this criterion. The criterion of normative adequacy requires that our theory be capable of guiding action and I argue that a certain kind of substantive theory is needed to meet this requirement. (shrink)

It is notoriously difficult to find an intuitively satisfactory rule for evaluating populations based on the welfare of the people in them. Standard examples, like total utilitarianism, either entail the Repugnant Conclusion or in some other way contradict common intuitions about the relative value of populations. Several philosophers have presented formal arguments that seem to show that this happens of necessity: our core intuitions stand in contradiction. This paper assesses the state of play, focusing on the most powerful of these (...) ‘impossibility theorems’, as developed by Gustaf Arrhenius. I highlight two ways in which these theorems fall short of their goal: some appeal to a supposedly egalitarian condition which, however, does not properly reflect egalitarian intuitions; the others rely on a background assumption about the structure of welfare which cannot be taken for granted. Nonetheless, the theorems remain important: they give insight into the difficulty, if not perhaps the impossibility, of constructing a satisfactory population axiology. We should aim for reflective equilibrium between intuitions and more theoretical considerations. I conclude by highlighting one possible ingredient in this equilibrium, which, I argue, leaves open a still wider range of acceptable theories: the possibility of vague or otherwise indeterminate value relations.

One-third of all human lives end in early death from poverty-related causes. Most of these premature deaths are avoidable through global institutional reforms that would eradicate extreme poverty. Many are also avoidable through global health-system reform that would make medical knowledge freely available as a global public good. The rules should be redesigned so that the development of any new drug is rewarded in proportion to its impact on the global disease burden (not through monopoly rents). This reform would bring (...) drug prices down worldwide close to their marginal cost of production and would powerfully stimulate pharmaceutical research into currently neglected diseases concentrated among the poor. Its feasibility shows that the existing medical-patent regime (trade-related aspects of intellectual property rights—TRIPS—as supplemented by bilateral agreements) is severely unjust—and its imposition a human-rights violation on account of the avoidable mortality and morbidity it foreseeably produces.

In his Psychologie vom empirischen Standpunkt Brentano proposed a view of consciousness that neither has room nor need for a subject of mental acts, a soul. Later he changed his mind: there is a soul that appears in consciousness. In this paper I will argue that Brentano’s change of view is not justified. The subjectless view of consciousness can be defended against Brentano’s argument and it is superior to its predecessor.

A recent study of moral intuitions, performed by Joshua Greene and a group of researchers at Princeton University, has recently received a lot of attention. Greene and his collaborators designed a set of experiments in which subjects were undergoing brain scanning as they were asked to respond to various practical dilemmas. They found that contemplation of some of these cases (cases where the subjects had to imagine that they must use some direct form of violence) elicited greater activity in certain (...) areas of the brain associated with emotions compared with the other cases. It has been argued (e.g., by Peter Singer) that these results undermine the reliability of our moral intuitions, and therefore provide an objection to methods of moral reasoning that presuppose that they carry an evidential weight (such as the idea of reflective equilibrium). I distinguish between two ways in which Greene's findings lend support for a sceptical attitude towards intuitions. I argue that, given the first version of the challenge, the method of reflective equilibrium can easily accommodate the findings. As for the second version of the challenge, I argue that it does not so much pose a threat specifically to the method of reflective equilibrium but to the idea that moral claims can be justified through rational argumentation in general.

Health-related quality of life is the ultimate general goal for medicine, health care and public health, including health promotion and health education. The other important general goal is health-related welfare. The aim of the paper is to explain what this means and what the consequences of these assumptions are for health work. This involves defining the central terms “health”, “quality of life” and “welfare” and showing what their conceptual relations are. Health-related quality of life has two central meanings: health-related well-being, (...) which constitutes quality of life, and health as ability, which contributes causally to quality of life. Four meanings of health-related welfare are put forward: general well-being, health as ability, other inner properties of the individual, and external factors. States and processes covered by these categories contribute causally to health-related quality of life. Finally, using these distinctions, some more specific goals for medicine and health care, on the one hand, and for public health and health promotion, on the other, are outlined. In the former fields work is primarily directed towards changing the health-related quality of life of the individual through direct measures, “manipulating” the individual, whereas public health work and health promotion primarily use indirect measures and further health through various sorts of health-related welfare changes, e.g. through changing the environment.

This paper argues that the principles of instrumental rationality apply primarily to extended action through time. Most philosophers assume that rational requirements and principles govern in the first instance momentary mental states, as opposed to governing extended intentional actions directly. In the case of instrumental rationality, the relevant mental states or attitudes would typically be preferences, decisions, or intentions. In fact, even those who recognize the extended nature of our agency still assume that rational requirements apply primarily to mental states (...) at a moment in time. Such views try to do justice to the extended nature of our agency by postulating rational requirements that apply in the first instance to plans, policies, and intentions more generally. The paper focuses on the central case of requirements and reasons governing the reconsideration of intentions and argues that these requirements or reasons are either superfluous or invalid.I argue that a proper conception of instrumental reasoning that applies directly to actions turn out to have surprising consequences. In fact, this conception allows us to see that policies, projects and the like are best understood as instances of extended actions, and that the instrumental requirements that apply to projects and policies are exactly the same as the instrumental requirements that apply to ordinary extended actions. Finally, I argue that the resulting theory of instrumental rationality is a significant improvement over theories that rely on principles governing intentions. (shrink)

Empowerment is a concept that has been much used and discussed for a number of years. However, it is not always explicitly clarified what its central meaning is. The present paper intends to clarify what empowerment means, and relate it to the goals of health promotion. The paper starts with the claim that health-related quality of life is the ultimate general goal for health promotion, and continues by briefly presenting definitions of some central concepts: “welfare” “health” and “quality of life”. (...) Several suggestions as to what empowerment is are then discussed: autonomy, freedom, knowledge, self-esteem, self-confidence, and control over health or life. One conclusion of this discussion is that empowerment can be seen as a complex goal which includes aspects of the three central concepts welfare, health and quality of life. To the extent that the empowerment goals aimed at are health-related, it is concluded that empowerment is a legitimate goal for health promotion. But empowerment is not only a goal, it can also be described as a process or as an approach. This process, or approach, in a fundamental way involves the participants in problem formulation, decision making and action, which means that the experts have to relinquish some of their control and power.

There is a rich tradition within game theory, decision theory, economics, and philosophy correlating practical rationality with impartiality, and spatial and temporal neutrality. I argue that in some cases we should give priority to people over both times and places, and to times over places. I also show how three plausible dominance principles regarding people, places, and times conflict, so that we cannot accept all three. However, I argue that there are some cases where we should give priority to times (...) over people, suggesting that there is impersonal value to the distribution of high quality life over different times.

Can a society be just if it ignores the plight of other societies? Does it matter whether those societies are contemporaries? Moral “purists” are likely to assume that the answer to these questions must be “no.” Relying on familiar claims about impartiality or universalizability, the purist is likely to assert that the dictates of justice have no bounds, that they extend with equal strength across space and time. On this view, if, for example, justice requires us to maximize the expectations (...) of the worst-off group in our society, it also requires us to maximize the expectations of the worst-off group in any society, at any time, so far as it is in our power to do so. Is such a position plausible? Is it more plausible than alternative positions? I am unsure about the answers to these questions, but both the questions, and the answers, are important. Clearly, the nature and extent of a just society's obligations will vary markedly depending on the scope of the correct principles of justice. (shrink)

Split brains that result in two simultaneous streams of consciousness cut off from each other are wrongly held to be grounds for doubting the existence of the divinely created soul. The mistake is based on two related errors: first, a failure to appreciate the soul's dependence upon neurological functioning; second, a fallacious belief that if the soul is simple, i.e. without parts, then there must be a unity to its thought, all of its thoughts being potentially accessible to reflection or (...) even unreflective causal interactions. But a soul theorist can allow neurological events to keep some conscious thoughts unavailable to others. (shrink)

Conventionalists about promising believe that it is wrong to break a promise because the promisor takes advantage of a useful social convention only to fail to do his part in maintaining it. Anti-conventionalists claim that the wrong of breaking a promise has nothing essentially to do with a social convention. Anti-conventionalists are right that the social convention is not necessary to explain the wrong of breaking most promises. But conventionalists are right that the convention plays an essential role in any (...) satisfactory account of promising. A new conventionalism can explain this by appealing to special features of social conventions. Two of these special features have important implications for any moral requirements they mediate, such as the requirement to keep one's promises and the moral requirements attached to social or occupational roles. First, these requirements will not depend on features of a situation that are inaccessible to typical participants in the convention. Second, these requirements often cannot be tailored to fit the overly unusual circumstances of participants. (shrink)

I describe a thought experiment in which an agent must choose between suffering a greater pain in the past or a lesser pain in the future. This case demonstrates that the ‘temporal value asymmetry’ – our disposition to attribute greater significance to future pleasures and pains than to past – can have consequences for the rationality of actions as well as attitudes. This fact, I argue, blocks attempts to vindicate the temporal value asymmetry as a useful heuristic tied to the (...) asymmetry of causation. Since the two standard arguments for the rationality of the temporal value asymmetry appeal to causal asymmetry and the passage of time respectively, the failure of the causal asymmetry explanation suggests that the B-theory, which rejects temporal passage, has substantial revisionary implications concerning our attitudes toward past and future experience.

I argue that the use of a social discount rate to assess the consequences of climate policy is unhelpful and misleading. I consider two lines of justification for discounting: (i) ethical arguments for a "pure rate of time preference" and (ii) economic arguments that take time as a proxy for economic growth and the diminishing marginal utility of consumption. In both cases I conclude that, given the long time horizons, distinctive uncertainties, and particular costs and benefits at stake in the (...) climate context, discount rates are at best a poor proxy for the normative considerations they are meant to represent.

Accuracy‐first epistemology is an approach to formal epistemology which takes accuracy to be a measure of epistemic utility and attempts to vindicate norms of epistemic rationality by showing how conformity with them is beneficial. If accuracy‐first epistemology can actually vindicate any epistemic norms, it must adopt a plausible account of epistemic value. Any such account must avoid the epistemic version of Derek Parfit's “repugnant conclusion.” I argue that the only plausible way of doing so is to say that accurate credences (...) in certain propositions have no, or almost no, epistemic value. I prove that this is incompatible with standard accuracy‐first arguments for probabilism, and argue that there is no way for accuracy‐first epistemology to show that all credences of all agents should be coherent.

Enormous harms, such as climate change, often occur as the result of large numbers of individuals acting separately. In collective action problems, an individual has so little chance of making a difference to these harms that changing their behavior has insignificant expected utility. Even so, it is intuitive that individuals in many collective action problems should not be parts of groups that cause these great harms. This paper gives an account of when we do and do not have obligations to (...) change our behavior in collective action problems. It also addresses a question insufficiently explored in the literature on this topic: when obligations arising out of collective action problems conflict with other obligations, what should we do? The paper explains how to adjudicate conflicts involving two collective action problems and conflicts involving collective action problems and other sorts of obligations. (shrink)
