Each year, over 200 million people are infected with the malaria parasite, nearly half a million of whom succumb to the disease. Emerging genetic technologies could, in theory, eliminate the burden of malaria throughout the world by intentionally eradicating the mosquitoes that transmit the disease. In this paper, we offer an ethical examination of the intentional eradication of Anopheles gambiae, the main malaria vector of sub-Saharan Africa. In our evaluation, we focus on two main considerations: the benefit of alleviating the (...) malaria burden, and the loss of value that would accompany the eradication of the species. We outline a typology of the different ways in which species are valued or could be valuable, then use that typology to appraise the value of the species in question. We argue that Anopheles gambiae has minor (and redundant) instrumental value, little final subjective value and no objective final value. (shrink)

Should we research, develop, and deploy climate engineering technology? Drawing upon contemporary moral and political theory, this book offers a normative perspective on such questions, ultimately making the case in favor of research and regulation guided by norms of legitimacy, distributive justice, and procedural justice.

With the lack of progress there has been so far on climate change, some have begun researching the potential of geoengineering to allay future climatic harms. However, others contend that such research should be abandoned. One of the most‐cited reasons as to why research into geoengineering should be abandoned is the idea that such research sits at the top of slippery slope. The Slippery Slope Argument warns that even mere research into geoengineering will create institutional momentum, ultimately leading to the (...) deployment of a technology that is untested and perhaps morally objectionable. This article clearly lays out the Slippery Slope Argument against geoengineering research and analyses its premises. I claim that both the empirical premise – that research will inevitably lead to deployment – and the normative premise – that we have decisive moral reasons to avoid deployment – are questionable. The main conclusion of the article is that while we should be cognizant of the potential for research to lead to undesirable deployment scenarios, engaging in research need not necessarily lead inexorably to deployment. While insufficient to ground a moratorium on research, the Slippery Slope Argument points to the need for regulation and oversight in order to prevent undesirable deployment. (shrink)

Gene drive technology has immense potential. The ability to bypass the laws of Mendelian inheritance and almost ensure the transmission of specific genetic material to future generations creates boundless possibilities. But alongside these boundless possibilities are major social and ethical issues. This article aims to introduce gene drive technology, some of its potential applications, and some of the social and ethical issues that arise during research into the technology. For example, is investigation into gene drives hubristic? Would applications of gene (...) drives count as technological fixes? Or does research into such a technology sit on a slippery slope or lock us in to its full‐scale use? Are there perverse effects of engaging in research, and, most importantly, who ought to be included in the decision‐making process regarding research and field trials? Understanding the basic ethical landscape of this technology will prove invaluable to the public, scientists, and policy‐makers as research moves forward. (shrink)

ABSTRACT: There is general agreement amongst those involved in the normative discussion about geoengineering that if we are to move forward with significant research, development, and certainly any future deployment, legitimate governance is a must. However, while we agree that the abstract concept of legitimacy ought to guide geoengineering governance, agreement surrounding the appropriate conception of legitimacy has yet to emerge. Relying upon Allen Buchanan’s metacoordination view of institutional legitimacy, this paper puts forward a conception of legitimacy appropriate for geoengineering (...) governance, outlining five normative criteria an institution ought to fulfill if it is to justifiably coordinate our action around geoengineering.

Defined as the “deliberate, large-scale manipulation of the planetary environment in order to counteract anthropogenic climate change,” geoengineering is an umbrella term that captures a variety of different technologies. This chapter will offer a concise overview of geoengineering as a response to anthropogenic climate change, with a primary focus on the ethical aspects this grouping of technologies engenders. We will start by exploring why it is that we are even considering these technologies rather than just doubling down on mitigation and (...) adaptation, and then move into a brief explanation of some of the different technologies under consideration. With that brief explanation out of the way, we will then introduce a number of ethical considerations that some or all of the technologies give rise to. For the sake of organization, we will look at different ethical considerations that arise: (1) during research into these technologies; (2) after deployment or full-scale use of these technologies; and (3) in the kind of world in which these technologies have become the new normal.

In this paper I first argue that when answering the question of whether or not governments may restrict emigration, Brock and Blake are staking out positions not astronomically far from one another. Despite the ostensibly large philosophical gap between the two, both think that certain governments may restrict emigration when such restriction is agreed to in a morally binding contract. Secondly, both authors think that there are specific “circumstances” or “conditions” under which a contract that restricts emigration can be morally (...) binding. This second part of the paper will pose some questions that explore these various circumstances or conditions. The ultimate aim of the paper is to help point the debate in the right direction so as to further develop an answer to the question of whether or not governments may restrict emigration. (shrink)

Abstract:A placebo is an intervention that is believed to lack specific pharmacological or physiological efficacy for a patient's condition. While placebo-controlled trials are considered the gold standard when it comes to researching and testing new pharmacological treatments, the use of placebos in clinical practice is more controversial. The focus of this case study is an undisclosed placebo trial used as an attempt to diagnose a patient's complex and unusual symptomology. In this case, the placebo was used not just as a (...) treatment, but as a diagnostic intervention in order to determine the best course of treatment for a patient. Could the deceptive use of a placebo be justified in clinical practice on the grounds of beneficence? (shrink)

With the significant disconnect between the collective aim of limiting warming to well below 2°C and the current means proposed to achieve such an aim, the goal of this paper is to offer a moral assessment of prominent alternatives to current international climate policy. To do so, we’ll outline five different policy routes that could potentially bring the means and goal in line. Those five policy routes are: (1) exceed 2°C; (2) limit warming to less than 2°C by economic de-growth; (...) (3) limit warming to less than 2°C by traditional mitigation only; (4) limit warming to less than 2°C by traditional mitigation and widespread deployment of Negative Emissions Technologies (NETs); and (5) limit warming to less than 2°C by traditional mitigation, NETs, and Solar Radiation Management as a fallback. In assessing these five policy routes, we rely primarily upon two moral considerations: the avoidance of catastrophic climate change and the right to sustainable development. We’ll conclude that we should continue to aim at the two-degree target, and that to get there we should use aggressive mitigation, pursue the deployment of NETs, and continue to research SRM.

Some scientists suggest that it might be possible to reflect a portion of incoming sunlight back into space to reduce climate change and its impacts. Others argue that such solar radiation management (SRM) geoengineering is inherently incompatible with democracy. In this article, we reject this incompatibility argument. First, we counterargue that technologies such as SRM lack innate political characteristics and predetermined social effects, and that democracy need not be deliberative to serve as a standard for governance. We then rebut each (...) of the argument’s core claims, countering that (1) democratic institutions are sufficiently resilient to manage SRM, (2) opting out of governance decisions is not a fundamental democratic right, (3) SRM may not require an undue degree of technocracy, and (4) its implementation may not concentrate power and promote authoritarianism. Although we reject the incompatibility argument, we do not argue that SRM is necessarily, or even likely to be, democratic in practice. (shrink)

Psychologists and psychiatrists recently started using electronic mail (e-mail) to conduct therapy. This article explores relevant ethical and legal issues including, among others, the nature of the professional relationship, boundaries of competence, informed consent, treating minors, confidentiality, and the duty to warn and protect. To illustrate these complex issues, two services currently operating are discussed. To address potential hazards to clients and the profession, a new ethical standard for e-mail therapists is offered.

This book tells a single story, in many voices, about a serious and sustained set of changes in mathematics teaching practice in a high school and how those efforts influenced and were influenced by a local university. It includes the writings and perspectives of high school students, high school teachers, preservice teacher candidates, doctoral students in mathematics education and other fields, mathematics teacher educators, and other education faculty. As a whole, this case study provides an opportunity to reflect on reform (...) visions of mathematics for all students and the challenges inherent in the implementation of these visions in US schools. It challenges us to rethink boundaries between theory and practice and the relative roles of teachers and university faculty in educational endeavors. (shrink)

Computational philosophy is the use of mechanized computational techniques to unearth philosophical insights that are either difficult or impossible to find using traditional philosophical methods. Computational metaphysics is computational philosophy with a focus on metaphysics. In this paper, we (a) develop results in modal metaphysics whose discovery was computer assisted, and (b) conclude that these results work not only to the obvious benefit of philosophy but also, less obviously, to the benefit of computer science, since the new computational techniques that (...) led to these results may be more broadly applicable within computer science. The paper includes a description of our background methodology and how it evolved, and a discussion of our new results. (shrink)

The nature of well-being is one of the most enduring and elusive subjects of human inquiry. Well-Being draws upon the latest scientific research to transform our understanding of this ancient question. With contributions from leading authorities in psychology, social psychology, and neuroscience, this volume presents the definitive account of current scientific efforts to understand human pleasure and pain, contentment and despair. The distinguished contributors to this volume combine a rigorous analysis of human sensations, emotions, and moods with a broad assessment (...) of the many factors, from heredity to nationality, that bear on our well-being. Using the tools of experimental science, the contributors confront the puzzles of human likes and dislikes. Why do we grow accustomed and desensitized to changes in our lives, both good and bad? Does our happiness reflect the circumstances of our lives or is it determined by our temperament and personality? Why do humans acquire tastes for sensations that are initially painful or unpleasant? By examining the roots of our everyday likes and dislikes, the book also sheds light on some of the more extreme examples of attraction and aversion, such as addiction and depression. Among its wide ranging inquiries, Well-Being examines systematic differences in moods and behaviors between genders, explaining why women suffer higher rates of depression and anxiety than men, but are also more inclined to express positive emotions. The book also makes international comparisons, finding that some countries' populations report higher levels of happiness than others. The contributors deploy an array of methods, from the surveys and questionnaires of social science to psychological and physiological experiments, to develop a comprehensive new approach to the study of well-being. They show how the sensory pleasures of the body can tells us something about the higher pleasures of the mind and even how the effectiveness of our immune system can depend upon the health of our social relationships.

Principia Logico-Metaphysica contains a foundational logical theory for metaphysics, mathematics, and the sciences. It includes a canonical development of Abstract Object Theory [AOT], a metaphysical theory that distinguishes between ordinary and abstract objects. This article reports on recent work in which AOT has been successfully represented and partly automated in the proof assistant system Isabelle/HOL. Initial experiments within this framework reveal a crucial but overlooked fact: a deeply-rooted and known paradox is reintroduced in AOT when the logic of complex terms (...) is simply adjoined to AOT’s specially formulated comprehension principle for relations. This result constitutes a new and important paradox, given how much expressive and analytic power is contributed by having the two kinds of complex terms in the system. Its discovery is the highlight of our joint project and provides strong evidence for a new kind of scientific practice in philosophy, namely, computational metaphysics. Our results were made technically possible by a suitable adaptation of Benzmüller’s metalogical approach to universal reasoning by semantically embedding theories in classical higher-order logic. This approach enables one to reuse state-of-the-art higher-order proof assistants, such as Isabelle/HOL, for mechanizing and experimentally exploring challenging logics and theories such as AOT. Our results also provide a fresh perspective on the question of whether relational type theory or functional type theory better serves as a foundation for logic and metaphysics. (shrink)

Anthropologists have documented substantial cross-society variation in people’s willingness to treat strangers with impartial, universal norms versus favoring members of their local community. Researchers have proposed several adaptive accounts for these differences. One variant of the pathogen stress hypothesis predicts that people will be more likely to favor local in-group members when they are under greater infectious disease threat. The material security hypothesis instead proposes that institutions that permit people to meet their basic needs through impartial interactions with strangers reinforce (...) a tendency toward impartiality, whereas people lacking such institutions must rely on local community members to meet their basic needs. Some studies have examined these hypotheses using self-reported preferences, but not with behavioral measures. We conducted behavioral experiments in eight diverse societies that measure individuals’ willingness to favor in-group members by ignoring an impartial rule. Consistent with the material security hypothesis, members of societies enjoying better-quality government services and food security show a stronger preference for following an impartial rule over investing in their local in-group. Our data show no support for the pathogen stress hypothesis as applied to favoring in-groups and instead suggest that favoring in-group members more closely reflects a general adaptive fit with social institutions that have arisen in each society.

All other things being equal the parser favors attaching an ambiguous modifier to the most recent possible site. A plausible explanation is that locality preferences such as this arise in the service of minimizing memory costs—more distant sentential material is more difficult to reactivate than more recent material. Note that processing any sentence requires linking each new lexical item with material in the current parse. This often involves the construction of long‐distance dependencies. Under a resource‐limited view of language processing, lengthy (...) integrations should induce difficulty even in unambiguous sentences. To date there has been little direct quantitative evidence in support of this perspective. This article presents 2 self‐paced reading studies, which explore the hypothesis that dependency distance is a fundamental determinant of reading complexity in unambiguous constructions in English. The evidence suggests that the difficulty associated with integrating a new input item is heavily determined by the amount of lexical material intervening between the input item and the site of its target dependents. The patterns observed here are not straightforwardly accounted for within purely experience‐based models of complexity. Instead, this work supports the role of a memory bottleneck in language comprehension. This constraint arises because hierarchical linguistic relations must be recovered from a linear input stream.

In the months preceding the writing of this review, bioethics has been in the news a great deal. In congressional and public policy debates surrounding stem cell research, human cloning, and the Human Genome Project, bioethics and bioethicists have gained national attention and been subject to public scrutiny. Commentators have asked who these self-appointed moral experts are to tell us what is right and wrong.

In the beginning of the COVID pandemic, researchers and bioethicists called for human challenge trials to hasten the development of a vaccine for COVID. However, the fact that we lacked a specific, highly effective treatment for COVID led many to argue that a COVID challenge trial would be unethical and we ought to pursue traditional phase III testing instead. These ethical objections to challenge trials may have slowed the progress of a COVID vaccine, so it is important to evaluate their (...) merit. One common way of doing so is to make an analogy to other social practices that are relevantly similar and which we currently sanction. We submit that non-directed live organ donation (NDLOD) is a promising analogy. After arguing that the risks to volunteers for each activity appear similar, we explore potential disanalogies that would undermine the comparison. We note that there are differences in both the kind and certainty of benefit secured by NDLOD compared to challenge trials. We conclude these differences are insufficient to make NDLOD permissible and challenge trials impermissible. Ultimately, if we think the risks associated with NDLOD are ethically permissible, then we should think the same of the risks associated with COVID challenge trials. (shrink)

Two self-paced reading experiments investigated several factors that influence the comprehension complexity of singly-embedded relative clauses (RCs) in English. Three factors were manipulated in Experiment 1, resulting in three main effects. First, object-extracted RCs were read more slowly than subject-extracted RCs, replicating previous work. Second, RCs that were embedded within the sentential complement of a noun were read more slowly than comparable RCs that were not embedded in this way. Third, and most interestingly, object-modifying RCs were read more slowly than (...) subject-modifying relative clauses. This result contradicts one of the central tenets of complexity research: that nested sentences are harder to understand than their right-branching equivalents (e.g., Miller and Chomsky 1963). It is hypothesized that this result followed from a combination of two information-flow factors: (1) background information is usually presented early in a sentence; and (2) restrictive RCs—the form of the RCs in Experiment 1—usually convey background information. Experiment 2 tested this hypothesis by comparing restrictive and non-restrictive RCs— which generally provide new information—in both subject- and objectmodifying positions. The results of the experiment were as predicted by the information-flow account: Only restrictive RCs were read more slowly when modifying objects. It is concluded that both resource and information-flow factors need to be considered in explaining RC complexity effects. (shrink)

We advance a model of human probability judgment and apply it to the design of an extrapolation algorithm. Such an algorithm examines a person's judgment about the likelihood of various statements and is then able to predict the same person's judgments about new statements. The algorithm is tested against judgments produced by thirty undergraduates asked to assign probabilities to statements about mammals.

Establishing reasonable, prior distributions remains a significant obstacle for the construction of probabilistic expert systems. Human assessment of chance is often relied upon for this purpose, but this has the drawback of being inconsistent with axioms of probability. This article advances a method for extracting a coherent distribution of probability from human judgment. The method is based on a psychological model of probabilistic reasoning, followed by a correction phase using linear programming.

Scientific advancement is inextricably linked to cultural advancement, and historically the arts have worked hand in hand with technological change. This essay explores some of the connections that exist between science, technology, and the arts, privileging instances where technological change resulted in new forms of artistic creation. Although the role of the arts in contemporary society has ebbed in comparison to that of technology and science, the essay argues that quality, meaningfulness, and longevity are key components in how the arts (...) can retain cultural value in today’s technocentric world. It explores significant instances from the history of music and visual art as the authors make the case that the methods of science and art are both distinct yet commensurate in their ability to shape the values and ideas of contemporary society.
