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.

Simon Saunders and David Wallace attempt to use a modified form of David Lewis's analysis of personal fission to ground the claim that prior to undergoing Everett branching an informed subject can be uncertain about which outcome s/he will observe.

It includes also a right for less than perfect parents to the use of IVF, and for IVF doctors to assist them, if they want and can (...) agree about the terms. (shrink)

In their article “Is There a Prima Facie Duty to Preserve Genetic Integrity in Conservation Biology?” Yasha Rower and Emma Harris argue that there is no underived prima facie obligation to preserve genetic integrity. In particular, it is argued that there is no such obligation because genetic integrity has no intrinsic value. In this commentary I raise doubts about this part of the authors’ argument. I argue that there might well be at least prima facie value in genetic integrity, that (...) the Moorean isolation test the authors use might not work in their favour, and that connecting genetic integrity to the idea of identity might work against the authors’ argument.

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)

This article examines some selected ethical issues in human space missions including human missions to Mars, particularly the idea of a space refuge, the scientific value of space exploration, and the possibility of human gene editing for deep-space travel. Each of these issues may be used either to support or to criticize human space missions. We conclude that while these issues are complex and context-dependent, there appear to be no overwhelming obstacles such as cost effectiveness, threats to human life or (...) protection of pristine space objects, to sending humans to space and to colonize space. The article argues for the rationality of the idea of a space refuge and the defensibility of the idea of human enhancement applied to future deep-space astronauts. (shrink)

Many philosophers maintain that the ability to do otherwise is compatible with comprehensive divine foreknowledge but incompatible with the truth of causal determinism. But the Fixity of the Past principle underlying the rejection of compatibilism about the ability to do otherwise and determinism appears to generate an argument also for the incompatibility of the ability to do otherwise and divine foreknowledge. By developing an account of ability that appeals to the notion of explanatory dependence, we can replace the Fixity of (...) the Past with a principle that does not generate this difficulty. I develop such an account and defend it from objections. I also explore some of the account's implications, including whether the account is consistent with presentism. (shrink)

This research examines the practice of cryonics and provides empirical evidence for an improved understanding of the motivations and attitudes of participants. Cryonics is the freezing of a person who has died of a disease in hopes of restoring life at some future time when a cure may be available. So far, about 300 people have been cryopreserved, and an additional 1200 have enrolled in such programs. The current work has three vectors. First, the results of a worldwide cryonics survey (...) carried out as part of this research are discussed. Second, a theoretical model is developed from the survey results to propose a Theory of Cryonic Life Extension which explains an individual’s decision to select cryopreservation. Third, the most distinctive survey result, a conceptualization of personal identity malleability, is extended with a philosophical formulation. Personal identity is found to be emergent, not fundamental, and thus may continue to evolve in concept and application, particularly in the longer time frames implicated by cryonics. The potential consequences of this work are that the conceptual norms materializing in the cryonics community could be forerunners of wider societal trends of how humans understand themselves as subjects in an era increasingly configured by science and technology.

In recent time there has been ample discussion concerning censorship of research conducted in two labs involved in avian influenza virus research.

Anthropogenic climate change poses some difficult ethical quandaries for non-anthropocentrists. While it is hard to deny that climate change is a substantial moral ill, many types of non-human organisms stand to benefit from climate change. Modelling studies provide evidence that net primary productivity (NPP) could be substantially boosted, both regionally and globally, as a result of warming from increased concentrations of greenhouse gases. The same holds for deployment of certain types of climate engineering, or large-scale, technological modifications of the global (...) environment in order to prevent or slow anthropogenic climate change. For example, solar radiation management with stratospheric aerosol injections could benefit plant life by promoting enhanced photosynthesis, increasing diffuse radiation, and reducing heat stress. This has a surprising implication: from some non-anthropocentric perspectives, certain scenarios of climate change and climate engineering might bring about morally better states of affairs when compared to emission-mitigation baselines.

If deployed, aerosol geoengineering (AG) could involve unfairness to both present and future parties. I discuss three broad risks of unfairness that an AG deployment policy might carry: (1) causing disproportionate harm to those least responsible for climate change, (2) burdening future parties with the costs and risks of AG, and (3) excluding some interested parties from contributing to AG decision-making. Yet despite these risks, it may be too hasty to reject AG deployment as a potential climate change policy. I (...) argue that since it is very unlikely that a completely fair climate change policy will be pursued, we have ethical reason to prefer some “incompletely fair” policy. Given various facts about our world, it might be the case that some AG policy is ethically preferable to many other feasible climate change policies, even if AG carries deeply problematic risks of unfairness.

Many theories of moral status that are intended to ground pro-choice views on abortion tie full moral status to advanced cognitive capabilities. Extant accounts of this kind are inconsistent with the intuition that the profoundly cognitively disabled have full moral status. This paper improves upon these extant accounts by combining an anti-luck condition with Steinbock’s stratification of moral status into two levels. On the resulting view, a being has full moral status if and only if she has moral status and (...) has had advanced cognitive capacities, has the potential to develop such capacities, or would have had such capacities were it not for luck. I argue that modal accounts of luck provide a non-speciesist basis for attributing the lack of advanced cognitive capacities in humans to luck without doing the same for non-human animals. (shrink)

ABSTRACTI defend the Interdependency Thesis, according to which rational evaluations of dispositions and actions are made in light of each other. I invoke a model of rationality that relies on various levels of consistency existing between an agent's reasons for adopting a moral disposition, the argument for the moral theory she endorses, her desires, disposition, and choice to be a moral person as reflected in the maxim she adopts. The Interdependency Thesis shows that we do not need to demonstrate the (...) rationality of every morally required action in order to defeat scepticism fully. (shrink)

Traditionally, the problem of defeating scepticism about the rationality of morality is that of showing that every morally required act is rationally required. Little or no direct attention has been paid to whether we must also show that it is rational for the agent to have and act from the morally appropriate motive, whatever that may be. This is not to say that philosophers have entirely ignored the issue of motives; a fair number—Kant and Aristotle come to mind—are concerned in (...) part with the kind of motive agents ought to have and from which they ought to act. But the link to scepticism has not been clearly made. At issue is whether scepticism is fully defeated if we show that every morally required act is rationally required, even if we leave it possible that a fully rational person who performs the act just “goes through the motions” in doing so.

With respect to questions of fact, people use heuristics – mental short-cuts, or rules of thumb, that generally work well, but that also lead to systematic errors. People use moral heuristics too – moral short-cuts, or rules of thumb, that lead to mistaken and even absurd moral judgments. These judgments are highly relevant not only to morality, but to law and politics as well. Examples are given from a number of domains, including risk regulation, punishment, reproduction and sexuality, and the (...) act/omission distinction. In all of these contexts, rapid, intuitive judgments make a great deal of sense, but sometimes produce moral mistakes that are replicated in law and policy. One implication is that moral assessments ought not to be made by appealing to intuitions about exotic cases and problems; those intuitions are particularly unlikely to be reliable. Another implication is that some deeply held moral judgments are unsound if they are products of moral heuristics. The idea of error-prone heuristics is especially controversial in the moral domain, where agreement on the correct answer may be hard to elicit; but in many contexts, heuristics are at work and they do real damage. Moral framing effects, including those in the context of obligations to future generations, are also discussed. (shrink)

Since philosophers began thinking seriously about the moral status of non-human animals, many of the practices we once took for granted have come to be condemned as unjustifiable, among them our reliance on animals as a food source. While the arguments which have been adduced in support of moral vegetarianism invoke quite different moral frameworks, they begin with a common concern for the welfare of animals. In the real world of practising vegetarians, this concern tends to be subordinated to considerations (...) of health or food scarcity. Philosophical vegetarians need not deny, and have not denied, the importance of these further considerations. But among philosophers the case for moral vegetarianism has rested primarily on arguments from animal welfare. (shrink)

Metaethics is often dominated by both realist views according to which moral claims are made true by either non-natural or natural properties and by non-cognitivist views according to which these claims express desire-like attitudes. It is sometimes suggested that constructivism is a fourth alternative, but it has remained opaque just how it differs from the other views. To solve this problem, this article first describes a clear constructivist theory based on Crispin Wright’s anti-realism. It then outlines an argumentative strategy that (...) can be used to argue against constructivist views about practical reasons. The rest of the article explains how the outlined constructivist metaethical framework, reasons, and contractualism in normative ethics can still be used to create a new viable metaethical constructivist position about right and wrong.

Justice is a contested concept. There are many different and competing conceptions, i.e. interpretations of the concept. Different domains of justice deal with different fields of application of justice claims, such as structural justice, distributive justice, participatory justice or recognition. We present a formal conceptual structure of justice applicable to all these domains. We show that conceptions of justice can be described by specifying the following conceptual elements: the judicandum, the community of justice including claim holders and claim addressees, their (...) claims, the informational base for the assessment, the principles of justice, and on a more practical level, the instruments of justice. By specifying these conceptual elements of justice, it is possible to analyse and compare different conceptions of justice, to assess their internal consistency, to explore new definitions of justice in an analytical way, and to explicate an idea of justice in a manner that provides concrete links to the relevant context.

Abstract:We examine the moral and managerial significance of some empirical studies in cognitive psychology. We suggest that these results may plausibly be interpreted as expressing deontological commitments of experimental subjects, even though psychologists who discuss the results seem to suppose that they show that people are irrational consequentialists. We argue that the plausibility of our interpretation suggests how managers who wish to take seriously entrenched social views on morality might best craft corporate policy on corporate responsibility, and we suggest that (...) the form of argument we employ may be regarded as a kind of appeal to reflective equilibrium.

Francis Beckwith’s Defending life: a moral and legal case against abortion choice defends the pro-life position on moral, legal and political grounds. In this critical notice I consider three key issues and argue that Beckwith’s treatment of each of them is unpersuasive. The issues are: (1) whether abortion is politically justified by the principle that we should err on the side of liberty in the face of reasonable disagreement over the moral status of the fetus; (2) whether the fetus’s natural (...) capacity or genetic propensity to develop rationality and communication is sufficient to give it a moral right to life; and (3) whether abortion is morally justified on the basis of bodily rights. I also show that Beckwith’s book fails to consider several important issues and arguments. (shrink)

Derek Parfit, Philip Pettit and Michael Smith defend a version of consequentialism that covers everything. I argue that this version of consequentialism is false. Consequentialism, I argue, can only cover things that belong to a combination of things that agents can bring about.

Personal Identity theorists as diverse as Derek Parfit, Marya Schechtman and Galen Strawson have noted that the experiencing subject (the locus of present psychological experience) and the person (a human being with a career/narrative extended across time) are not necessarily coextensive. Accordingly, we can become psychologically alienated from, and fail to experience a sense of identity with, the person we once were or will be. This presents serious problems for Locke's original account of “sameness of consciousness” constituting personal identity, given (...) the distinctly normative (and indeed eschatological) focus of his discussion. To succeed, the Lockean project needs to identify some phenomenal property of experience that can constitute a sense of identity with the self figured in all moments to which consciousness can be extended. I draw upon key themes in Kierkegaard's phenomenology of moral imagination to show that Kierkegaard describes a phenomenal quality of experience that unites the experiencing subject with its past and future, regardless of facts about psychological change across time. Yet Kierkegaard's account is fully normative, recasting affective identification with past/future selves as a moral task rather than something merely psychologically desirable (Schechtman) or utterly contingent (Parfit, Strawson).

This paper outlines an account of the ethics of lying, which accommodates two main ideas about lying. The first of these, Anti-Deceptionalism, is the view that lying does not necessarily involve intentions to deceive. The second, Anti-Absolutism, is the view that lying is not always morally wrong. It is argued that lying is not wrong in itself, but rather the wrong in lying is explained by different factors in different cases. In some cases such factors may include deceptive intentions on (...) the part of the liar. In other cases, where such intentions are not found, the wrong in lying may be explained by other factors. Moreover, it is argued that the interaction between considerations against lying and considerations against telling the truth are sensitive to the practical interests of those lied to. When the topic of the lie in question matters little to the victim's rational decision making, the threshold for when considerations against telling the truth can outweigh considerations against lying are lowered. This account is seen to explain why lying to avoid little harm is sometimes permissible, and sometimes not. (shrink)

This essay examines the issue of false assumptions in models via a case study of a prominent economic model of sustainable development, wherein the assumption of an infinite future plays a central role. Two proposals are found to be helpful for this case, one based on the concept of derivational robustness and the other on understanding. Both suggest that the assumption of an infinite future, while arguably legitimate in some applications of the model, is problematic with respect to what I (...) call “Parfitian” welfare functions. This result is relevant to debates about discounting the future in economics and environmental ethics. (shrink)

Fritz Allhoff has recently offered an extremely compelling challenge to the morality of human cloning. He argues that a biological phenomenon, that of telomere shortening, undermines the moral permissibility of human cloning. Telomere shortening is caused by cell replication, and appears to be one of the central reasons that cells and organisms age and die. Allhoff considers a thirty-year-old woman who wishes to create a genetic clone. He notes that the DNA from her cell that would be used to create (...) the clone would have shortened telomeres—as it would have gone through many generations of cell replication. As a result, the clone would begin its existence with shortened telomeres; the clone’s telomeres would be the same length as the woman’s telomeres at the time of cloning. The moral problem lies in the fact that because of shortened telomeres, the clone will senesce more rapidly as compared with noncloned organisms, and would have increased susceptibility to degenerative conditions and diseases. Allhoff then goes on to argue that earlier senescence and disease susceptibility constitute a moral ground for rejecting cloning because “the life of a clone would be worse than that of a non-clone”. This line of argument is rooted in Parfit’s The Same Number Quality Claim : “If in either of two outcomes the same number of people would ever live, it would be bad if those who live are worse off, or have a lower quality of life, than those who would have lived”. Applying Parfit’s Q principle to cases of cloning, it could be argued that parents ought to produce children that would be maximally well off, and since clones would be worse off than children produced “normally,” it follows that parents should avoid cloning. As Allhoff puts it, “obviously sexual reproduction would not transfer shortened telomeres to offspring so, all else being equal, sexual reproduction is better than cloning ”. For this sort of line to pack any moral punch, Q must be interpreted rather strongly. (shrink)

English summary: Provocative Public Philosophy In 2017, I argued that people with Down syndrome cannot live full lives. This sparked a heated debated in the Norwegian public sphere.

Neoplatonism is alive and well today. It expresses itself in New Thought and the mind-cure movements derived from it. However, to avoid many ancient errors, Neoplatonism needs to be modernized. The One is just the simple origin from which all complex things evolve. The Good, which is not the One, is the best of all possible propositions. A cosmological argument is given for the One and an ontological argument for the Good. The presence of the Good in every thing is (...) Spirit. Spirit sits in the logical center of every body; it is surrounded by the regulatory forms of that body. Striving for the Good, Spirit seeks to correct the errors in its surrounding forms. To correct the errors in biological texts, modern Neoplatonists turn to the experimental method. This Neoplatonism is pantheistic not because of some theoretical definition of God but rather because of its practical focus on the shaping of Spirit. (shrink)
