Individuals with a variety of disabilities benefit greatly from the ADA provision of easy public access with their service dogs. However, the growing problem of non-disabled individuals passing off their pets as service dogs both threatens public safety and can result in denial of access for legitimate service dog teams. We argue that requiring certification of service dog teams and furnishing qualified teams with state-issued ID tags, following a process similar to that for obtaining accessible-parking placards, is the least intrusive (...) way to protect access for legitimate teams and protect public safety. While some consider a certification requirement for service dog teams to be burdensome, balanced against the harms posed by easy public access for untrained or inappropriate dogs, the mild burden is justified.

I explain the shutdown problem: the problem of designing artificial agents that (1) shut down when a shutdown button is pressed, (2) don’t try to prevent or cause the pressing of the shutdown button, and (3) otherwise pursue goals competently. I prove three theorems that make the difficulty precise. These theorems show that agents satisfying some innocuous-seeming conditions will often try to prevent or cause the pressing of the shutdown button, even in cases where it’s costly to do so. And (...) patience trades off against shutdownability: the more patient an agent, the greater the costs that agent is willing to incur to manipulate the shutdown button. I end by noting that these theorems can guide our search for solutions. (shrink)

Person-affecting views in population ethics state that (in cases where all else is equal) we’re permitted but not required to create people who would enjoy good lives. In this paper, I present an argument against every possible variety of person-affecting view. The argument takes the form of a dilemma. Narrow person-affecting views must embrace at least one of three implausible verdicts in a case that I call ‘Expanded Non-Identity.’ Wide person-affecting views run into trouble in a case that I call (...) ‘Two-Shot Non-Identity.’ One plausible practical upshot of my argument is as follows: we individuals and our governments should be doing more to reduce the risk of human extinction this century.

Informed consent is a central concept for empirical and theoretical research concerning pregnancy management decisions and is often taken to be one of the more fundamental goals of the profession of genetic counseling. Tellingly, this concept has been seen by disability communities as salutary, despite longstanding critiques made by disability activists, advocates, and scholars concerning practices involved in genetic counseling more generally. In this chapter, we show that the widespread faith in informed consent is misleading and can be detrimental to (...) the practice of genetic counseling as guided by concerns of justice and equity. We proceed in two steps. First, we explain how informed consent is flawed as a practical concept. Second, we show how the inadequacy of informed consent illuminates the animating core of disability critiques of genetic counseling: the issue of ableism. We argue that the problem of ableism cannot be solved with informed consent because it is not merely a problem of information, but also of epistemic schemas. We suggest that what we call critically informed consent is better suited to move genetic counseling from being aware of the problem of ableism to becoming actively anti-ableist. (shrink)

We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages. We argue that biologists regularly provide this type of explanation when they attribute conserved functions to phenotypic and genetic traits. The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and cell biology. (...) We use these examples to show how the study of conserved functions can integrate knowledge of a trait’s causal effects on fitness and its history of natural selection without invoking adaptation. We also show how conserved function provides a novel basis for addressing objections against evolutionary functions raised by Robert Cummins. (shrink)

This paper presents a holistic, contextualised case study of reintegration and trust repair at a UK utilities firm in the wake of its fraud and data manipulation scandal. Drawing upon conceptual frameworks of reintegration and organizational trust repair, we analyze the decisions and actions taken by the company in its efforts to restore trust with its stakeholders. The analysis reveals seven themes on the merits of proposed approaches for reintegration after an integrity violation , and novel insights on the role (...) of organizational identity, “changing of the guard” and cultural reforms alongside procedural modifications. The case further supports the dynamic nature of stakeholder salience across the reintegration process. The study both supports propositions from existing frameworks and suggests novel theoretical extensions for future research. (shrink)

Compassionate care: a moral dimension of nursingThis paper focuses on the concept of compassion and its meaning for nursing practice. Compassion is often considered to be an essential component of nursing care; however, it is difficult to identify what exactly comprises compassionate care. To begin with, there is a general discussion of the meaning of compassion and an examination of its common usage. An argument then is presented that compassion is more than just a natural response to suffering, rather that (...) it is a moral choice. The paper outlines the extent to which this concept has implications for nursing care, highlighting some of the obstacles that nurses need to overcome in order to maintain this essential moral value of the caring role.

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

Common wisdom holds that communication is impossible when messages are costless and communicators have totally opposed interests. This article demonstrates that such wisdom is false. Non-convergent dynamics can sustain partial information transfer even in a zero-sum signalling game. In particular, I investigate a signalling game in which messages are free, the state-act payoffs resemble rock–paper–scissors, and senders and receivers adjust their strategies according to the replicator dynamic. This system exhibits Hamiltonian chaos and trajectories do not converge to equilibria. This persistent (...) out-of-equilibrium behaviour results in messages that do not perfectly reveal the sender's private information, but do transfer information as quantified by the Kullback–Leibler divergence. This finding shows that adaptive dynamics can enable information transmission even though messages at equilibria are meaningless. This suggests a new explanation for the evolution or spontaneous emergence of meaning: non-convergent adaptive dynamics. (shrink)

Tracing the history of American sociology since the Civil War, the authors of this important volume explain the field′s diversity, its lack of unifying paradigms, its broad, eclectic research agenda and its general weakness as an institutional force in either academia or the policy arena. They highlight the equivocal and often contradictory missions that sociologists prescribe for themselves and the variable nature of human, financial and intellectual resources available to the profession.

According to Critical-Level Views in population axiology, an extra life improves a population only if that life’s welfare exceeds some fixed ‘critical level.’ An extra life at the critical level leaves the new population equally good as the original. According to Critical-Range Views, an extra life improves a population only if that life’s welfare exceeds some fixed ‘critical range.’ An extra life within the critical range leaves the new population incommensurable with the original. -/- In this paper, I sharpen some (...) old objections to these views and offer some new ones. Critical-Level Views cannot avoid certain Repugnant and Sadistic Conclusions. Critical-Range Views imply that lives featuring no good or bad components whatsoever can nevertheless swallow up and neutralise goodness or badness. Both classes of view entail that certain small changes in welfare correspond to worryingly large differences in contributive value. -/- I then offer a view that retains much of the appeal of Critical-Level and Critical-Range Views while avoiding the above pitfalls. On the Imprecise Exchange Rates View, the quantity of some good required to outweigh a given unit of some bad is imprecise. This imprecision is the source of incommensurability between lives and populations. (shrink)

Lexical views in population axiology can avoid the Repugnant Conclusion without violating Transitivity or Separability. However, they imply a dilemma: either some good life is better than any number of slightly worse lives, or else the ‘at least as good as’ relation on populations is radically incomplete. In this paper, I argue that Archimedean views face an analogous dilemma. I thus conclude that the lexical dilemma gives us little reason to prefer Archimedean views. Even if we give up on lexicality, (...) problems of the same kind remain. (shrink)

Reinhold Niebuhr's concept of ideology, a synthesis of the doctrine of sin and sociology of knowledge, denotes any claim to absolute truth with reilsvested interests. Tolerance, its anonym, is based on an acknowledgement of one's own fallibity and need for forgiveness. Niebuhr thus intertwines Luther's two »realms«, without mixing them up. His theory is deemed a major contribution to both theology and political science.

Arrhenius’s impossibility theorems purport to demonstrate that no population axiology can satisfy each of a small number of intuitively compelling adequacy conditions. However, it has recently been pointed out that each theorem depends on a dubious assumption: Finite Fine-Grainedness. This assumption states that there exists a finite sequence of slight welfare differences between any two welfare levels. Denying Finite Fine-Grainedness makes room for a lexical population axiology which satisfies all of the compelling adequacy conditions in each theorem. Therefore, Arrhenius’s theorems (...) fail to prove that there is no satisfactory population axiology. In this paper, I argue that Arrhenius’s theorems can be repurposed. Since all of our population-affecting actions have a non-zero probability of bringing about more than one distinct population, it is population prospect axiologies that are of practical relevance, and amended versions of Arrhenius’s theorems demonstrate that there is no satisfactory population prospect axiology. These impossibility theorems do not depend on Finite Fine-Grainedness, so lexical views do not escape them. (shrink)

Critical-set views avoid the Repugnant Conclusion by subtracting some constant from the welfare score of each life in a population. These views are thus sensitive to facts about biographical identity: identity between lives. In this paper, I argue that questions of biographical identity give us reason to reject critical-set views and embrace the total view. I end with a practical implication. If we shift our credences towards the total view, we should also shift our efforts towards ensuring that humanity survives (...) for the long term. (shrink)

Lewis signalling games are often used to explain how it is possible for simple agents to develop systems of conventional semantic meaning. In these games, all players obtain identical payoffs in every outcome. This is an unrealistic payoff structure, but it is often employed because it is thought that semantic meaning will not emerge if interests conflict. Here it is shown that not only is conventional meaning possible when interests conflict, but it is the most likely outcome in a finite (...) population model of learning known as the Moran process. On the basis of this result it is suggested that evolutionary game theory’s standard models may yield results that are systematically distorted for a class of signalling games that have the abstract structure of social dilemmas. 1 Introduction2 The Seduction Game3 Imitation Dynamics with Small Mutations4 Dynamics with Unverifiable Message5 Analysis of a Related Three-Strategy Game6 Conclusion.

Scientific research that could cause grave harm, either through accident or intentional malevolence, is known as dual-use research. Recent high-profile cases of dual-use research in the life sciences have led to debate about the extent to which restrictions on the conduct and dissemination of such research may impede scientific progress. We adapt formal models of scientific networks to systematically explore the effects that different regulatory schemes may have on a community’s ability to learn about the world. Our results suggest that, (...) contrary to common wisdom, some restrictions on the conduct and dissemination of dual-use research do not inhibit scientific progress and may actually aid communities in learning.

I explain and motivate the shutdown problem: the problem of creating artificial agents that (1) shut down when a shutdown button is pressed, (2) don’t try to prevent or cause the pressing of the shutdown button, and (3) otherwise pursue goals competently. I then propose a solution: train agents to have incomplete preferences. Specifically, I propose that we train agents to lack a preference between every pair of different-length trajectories. I suggest a way to train such agents using reinforcement learning: (...) we give the agent lower reward for repeatedly choosing same-length trajectories. (shrink)

Philosophers and social scientists have recently turned to Lewis sender–receiver games to provide an account of how lexical terms can acquire meaning through an evolutionary process. However, the evolution of meaning is contingent on both the particular sender–receiver game played and the choice of evolutionary dynamic. In this paper I explore some differences between models that presume an infinitely large and randomly mixed population and models in which a finite number of agents communicate with their neighbors in a social network. (...) My results show that communication with neighbors is more conducive to the evolution of meaning than communication with strangers. Additionally, I show that the behavior of the system is highly dependent on the topological structure of the social network. I argue that a specific class of networks—small world graphs—is especially conducive to the evolution of meaning. This is because small world graphs have a short characteristic path length while still maintaining a high degree of correlation between neighbors. Since many actual social networks, such as friendship networks and nervous systems, are conjectured to be small world structures, these results indicate that these networks are quite hospitable to the efficient evolution of meaning.

Cooperation and the allocation of common resources are core features of social behavior. Games idealizing both interactions have been studied separately. But here, rather than examining the dynamics of the individual games, the interactions are combined so that players first choose whether to cooperate, and then, if they jointly cooperate, they bargain over the fruits of their cooperation. It is shown that the dynamics of the combined game cannot simply be reduced to the dynamics of the individual games and that (...) both cooperation and fair division are more likely in the combined game than in the constituent games taken separately.

The current system of ethical review for medical research in the United Kingdom is changing from the current system involving large committees of 7–18 members reviewing every individual application to a system involving pre-review by small sub-committees of National Research Ethics Officers , who have a remit to approve studies if they believe there are no material ethical issues imposed by the research. The reliability of this new system depends on the reliability of the NREAs and in particular the ability (...) of small groups to effectively identify and appropriately assess the seriousness of all the material ethical issues that may be posed by an application. There is anecdotal evidence to suggest that many individual research ethics committee members have had experience of believing that a study presents no material ethical concerns, then on reaching the committee and discussing the application they realise that the committee feels it does present significant ethical concerns. If this is the case then this casts doubt on the reliability of NREAs or small groups to effectively identify ethically problematic research and appropriately respond to this to protect research participants. In this paper we describe a small questionnaire based piece of research carried out to assess how common this and other relevant experiences are. (shrink)

The Nature of Selection is a straightforward, self-contained introduction to philosophical and biological problems in evolutionary theory. It presents a powerful analysis of the evolutionary concepts of natural selection, fitness, and adaptation and clarifies controversial issues concerning altruism, group selection, and the idea that organisms are survival machines built for the good of the genes that inhabit them. "Sober's is the answering philosophical voice, the voice of a first-rate philosopher and a knowledgeable student of contemporary evolutionary theory. His book merits (...) broad attention among both communities. It should also inspire others to continue the conversation."-Philip Kitcher, Nature "Elliott Sober has made extraordinarily important contributions to our understanding of biological problems in evolutionary biology and causality. The Nature of Selection is a major contribution to understanding epistemological problems in evolutionary theory. I predict that it will have a long lasting place in the literature."-Richard C.

Approximately 50 years have passed since Judith Jarvis Thomson wrote A Defense of Abortion (1971). Her article has significantly shaped the philosophical literature on abortion. In this paper, I will summarize some of the interesting and important work done on the topic since Thomson's article. I will highlight Thomson as a defender of the claim that abortion is morally permissible and Don Marquis as an influential opponent of that claim. I will start by articulating Thomson's case, focusing on the violinist (...) analogy. I will underscore key questions, concepts, and objections the analogy raises. I will then examine briefly how philosophers have addressed some of these issues. Next, I will outline Marquis’ work, provide a similar commentary on it, and discuss some of its main responses. I will then survey other philosophers who have addressed abortion beyond the scope of providing specific replies to Thomson or Marquis. I will close by highlighting significant points of agreement and disagreement in the literature, as well as crucial gaps in the current research. The paper is not an attempt to address every work on the topic over the last five decades, nor is it aimed at taking a position on the moral permissibility of abortion. My goal is to provide an overview of the dialectic. (shrink)

Act consequentialism states that an act is right if and only if the expected value of its outcome is at least as great as the expected value of any other act’s outcome. Two objections to this view are as follows. The first is that act consequentialism cannot account for our normative ambivalence in cases where agents perform the right act out of bad motives. The second is that act consequentialism is silent on questions of character: questions like ‘What are the (...) right motives to have?’ and ‘What kind of person ought I be?’. These objections have been taken to motivate a move to global consequentialism, on which acts are not the only subjects of normative assessment. Motives and decision-procedures are also judged right or wrong by direct reference to their consequences. In this paper, I argue that these objections fail to motivate the move from act to global consequentialism. (shrink)

In this brief comment, we bring together two articles that appear in this special section. Jamieson et al. provide an overview of the biopsychosocial model of threat and challenge and suggest that stress-related arousal can be reappraised as a coping resource to facilitate challenge appraisals. Hernandez et al. review evidence for the link between well-being and health. We see a connection between these seemingly unrelated reviews: Well-being may improve health in part by shaping appraisals of stressors’ demands and appraisals of (...) coping resources. (shrink)

Clinicians at quaternary centers see part of their mission as providing hope when others cannot. They tend to see sicker patients with more complex disease processes. Part of this mission is offering longshot treatment modalities that are unlikely to achieve their stated goal, but conceivably could. When patients embark on such a treatment plan, it may fail. Often treatment toward an initial goal continues beyond the point at which such a goal is feasible. We explore the progression of care from (...) longshot to fantasy using two pediatric cases. This progression may be differentiated into four distinct stages of care related to the potential of achieving the initial goals of care. Physicians are often ill prepared for the progression of treatments from a longshot hope to an unfeasible and, therefore, typically unjustified intervention. We present a structured approach to guide clinicians at referral institutions where these situations may be common. The transition of care from “longshot” to “fantasy” is an inherent part of quaternary care for the sickest of patients that has been underexplored. Physicians are often poorly equipped to approach that transition. We advocate this approach to the shift from longshot to fantasy with the belief that such a structured method will have multiple benefits, including: reduced suffering for the patient; decreased emotional burden on patient and family; decreased provider moral distress; increased likelihood of seeking high quality palliative care earlier; and provision of honest and straightforward information to patients and their families.
