Background At the beginning of the coronavirus (Covid-19) pandemic, many non-Covid healthcare services were suspended. In April 2020, the Department of Health in England mandated that non-Covid services should resume, alongside the continuing pandemic response. This ‘resetting’ of healthcare services created a unique context in which it became critical to consider how ethical considerations did (and should) underpin decisions about integrating infection control measures into routine healthcare practices. We draw on data collected as part of the ‘NHS Reset Ethics’ project, (...) which explored the everyday ethical challenges of resetting England’s NHS maternity and paediatrics services during the pandemic. Methods Healthcare professionals and members of the public participated in interviews and focus group discussions. The qualitative methods are reported in detail elsewhere. The focus of this article is our use of Frith’s symbiotic empirical ethics methodology to work from our empirical findings towards the normative suggestion that clinical ethics should explicitly attend to the importance of relationships in clinical practice. This methodology uses a five-step approach to refine and develop ethical theory based on a naturalist account of ethics that sees practice and theory as symbiotically related. Results The Reset project data showed that changed working practices caused ethical challenges for healthcare professionals, and that infection prevention and control measures represented harmful barriers to the experience of receiving and offering care. For healthcare professionals, offering care as part of a relational interaction was an ethically important dimension of healthcare delivery. Conclusions Our findings suggest that foregrounding the importance of relationships across a hospital community will better promote the ethically important multi-directional expression of caring between healthcare professionals, patients, and their families. We offer two suggestions for making progress towards such a relational approach. First, that there is a change of emphasis in clinical ethics practice to explicitly acknowledge the importance of the relationships (including with their healthcare team) within which the patient is held. Second, that organisational decision-making should take into account the moral significance afforded to caring relationships by healthcare professionals, and the role such relationships can play in the negotiation of ethical challenges.

Xenotransplantation, or the use of animal cells, tissues and organs for humans, has been promoted as an important solution to the worldwide shortage of organs. While scientific studies continue to be done to address problems of rejection and the possibility of animal-to-human virus transfer, socio-ethical and legal questions have also been raised around informed consent, life-long monitoring, animal welfare and animal rights, and appropriate regulatory practices. Many calls have also been made to consult publics before policy decisions are made. This (...) paper describes the Canadian public consultation process on xenotransplantation carried out by the Canadian Public Health Association in an arm’s length process from Health Canada, the ministry overseeing government health policy and regulation. Focusing on six citizen fora conducted around the country patterned after the citizen jury deliberative approach, the paper describes the citizen panelists’ recommendations to hold off on proceeding with clinical trials and the rationales behind this recommendation. The consultation process is discussed in the context of constructive technology assessment, a framework which argues for broader input into earlier stages of technology innovation, particularly at the technology design stage.

Guattari's ecosophy has implications for many types of pedagogy practiced in the school. While Guattari never explicitly advocated the educational use of ecosophy, I explore in this article how it can be used as a lens to ‘read’ pedagogy in nuanced ways, highlighting oppressive premises and practices. I first discuss Guattari's ecosophy, defining key terms and advocating ecosophy as a philosophy that calls attention to the interactions and ‘parts’ of assemblages of existence—a philosophy radical and encompassing enough to make intelligible (...) the dynamic connections between various fields of existence, trajectories into the new, and trajectories more destructive in nature. I then offer a ‘reading’ of two different pedagogical strategies that have achieved a wide following in the last few decades: direct instruction, and critical pedagogy. Reading these pedagogies through ecosophy allows us to name more fully the troubling assumptions and lacunae to be found within them. (shrink)

The diverse array of plants at Kew is a haven for wildlife throughout the year. In spring, enchanting wildlfowl babies appear; summer flowers attract a host of insect pollinators; come autumn, parakeets and squirrels raid chestnuts, while in winter swans court – this is Heather Angel’s Wild Kew. In all, a stunning array of photographs and advice, the result of devoting a year to capturing Kew’s wildlife.

Over the past decade, feminist philosophers have gone a long way toward identifying and explaining the phenomenon that has come to be known as epistemic injustice. Epistemic injustice is injustice occurring within the domain of knowledge (e.g., knowledge production and transmission), which typically impacts structurally marginalized social groups. In this paper, we argue that, as they currently work, algorithms on social media exacerbate the problem of epistemic injustice and related problems of social distrust. In other words, we argue that algorithms (...) on social media recreate and reify the conditions that lead to some groups being systematically denied the full status of knowers, thereby corrupting the epistemic terrain and, with it, systems of social trust and cooperation. We argue that algorithms do this in two ways—namely, via what we are calling algorithmic targeting and algorithmic sorting. (shrink)

I argue that the best scientific package is anti-Humean in its ontology, but Humean in its laws. This is because potencies and the best system account of laws complement each other surprisingly well. If there are potencies, then the BSA is the most plausible account of the laws of nature. Conversely, if the BSA is the correct theory of laws, then formulating the laws in terms of potencies rather than categorical properties avoids three serious objections: the mismatch objection, the impoverished (...) worlds objection, and the metaphysical 'oomph' objection. I argue that combining anti-Humean properties with Humean laws into a Potency-Best System Account of Laws is a powerful and science-friendly account---something that people on both sides should be able to appreciate.

This study investigates the hypothesis that the advantage corporate social performance (CSP) yields in attracting human resources depends on the degree of job choice possessed by the job seeking population. Results indicate that organizational CSP is positively related to employer attractiveness for job seekers with high levels of job choice but not related for populations with low levels suggesting advantages to firms with high levels of CSP in the ability to attract the most qualified employees.

This study investigated the effects of internal and demographic variables on civic development in late adolescence using the construct civic purpose. We conducted surveys on civic engagement with 480 high school seniors, and surveyed them again two years later. Using multivariate regression and linear mixed models, we tested the main effects of civic purpose dimensions (beyond-the-self motivation, future civic intention), ethnicity, and education on civic development from Time 1 to Time 2. Results showed that while there is an overall decrease (...) in civic engagement in the transition out of high school, both internal and social factors protected participants from steep civic decline. Interaction effects varied. Ethnicity and education interacted in different ways with the dimensions of civic purpose to predict change in traditional and expressive political engagement, and community service engagement.

How looking beautiful has become a moral imperative in today’s world The demand to be beautiful is increasingly important in today's visual and virtual culture. Rightly or wrongly, being perfect has become an ethical ideal to live by, and according to which we judge ourselves good or bad, a success or a failure. Perfect Me explores the changing nature of the beauty ideal, showing how it is more dominant, more demanding, and more global than ever before. Heather Widdows argues (...) that our perception of the self is changing. More and more, we locate the self in the body--not just our actual, flawed bodies but our transforming and imagined ones. As this happens, we further embrace the beauty ideal. Nobody is firm enough, thin enough, smooth enough, or buff enough—not without significant effort and cosmetic intervention. And as more demanding practices become the norm, more will be required of us, and the beauty ideal will be harder and harder to resist. If you have ever felt the urge to "make the best of yourself" or worried that you were "letting yourself go," this book explains why. Perfect Me examines how the beauty ideal has come to define how we see ourselves and others and how we structure our daily practices—and how it enthralls us with promises of the good life that are dubious at best. Perfect Me demonstrates that we must first recognize the ethical nature of the beauty ideal if we are ever to address its harms. (shrink)

This paper addresses what we consider to be the most pressing challenge for the emerging science of consciousness: the measurement problem of consciousness. That is, by what methods can we determine the presence of and properties of consciousness? Most methods are currently developed through evaluation of the presence of consciousness in humans and here we argue that there are particular problems in application of these methods to nonhuman cases—what we call the indicator validity problem and the extrapolation problem. The first (...) is a problem with the application of indicators developed using the differences between conscious and unconscious processing in humans to the identification of other conscious vs. nonconscious organisms or systems. The second is a problem in extrapolating any indicators developed in humans or other organisms to artificial systems. However, while pressing ethical concerns add urgency to the attribution of consciousness and its attendant moral status to nonhuman animals and intelligent machines, we cannot wait for certainty and we advocate the use of a precautionary principle to avoid causing unintentional harm. We also intend that the considerations and limitations discussed in this paper can be used to further analyze and refine the methods of consciousness science with the hope that one day we may be able to solve the measurement problem of consciousness.

‘Sentience’ sometimes refers to the capacity for any type of subjective experience, and sometimes to the capacity to have subjective experiences with a positive or negative valence, such as pain or pleasure. We review recent controversies regarding sentience in fish and invertebrates and consider the deep methodological challenge posed by these cases. We then present two ways of responding to the challenge. In a policy-making context, precautionary thinking can help us treat animals appropriately despite continuing uncertainty about their sentience. In (...) a scientific context, we can draw inspiration from the science of human consciousness to disentangle conscious and unconscious perception (especially vision) in animals. Developing better ways to disentangle conscious and unconscious affect is a key priority for future research. (shrink)

One of the primary concerns in animal research is ensuring the welfare of laboratory animals. Modern views on animal welfare emphasize the role of animal sentience, i.e. the capacity to experience subjective states such as pleasure or suffering, as a central component of welfare. The increasing official recognition of animal sentience has had large effects on laboratory animal research. The Cambridge Declaration on Consciousness (Low et al., University of Cambridge, 2012) marked an official scientific recognition of the presence of sentience (...) in mammals, birds, and cephalopods. Animal sentience has furthermore been recognized in legislation in the European Union, UK, New Zealand and parts of Australia, with discussions underway in other parts of the world to follow suit. In this paper, we analyze this shift towards recognition of sentience in the regulation and practice in the treatment of laboratory animals and its effects on animal welfare and use. (shrink)

The primary goal of this paper is to propose a working analysis of the disposition of closed-mindedness. I argue that closed-mindedness (CM) is an unwillingness or inability to engage (seriously) with relevant intellectual options. Dogmatism (DG) is one kind of closed-mindedness: it is an unwillingness to engage seriously with relevant alternatives to the beliefs one already holds. I do not assume that the disposition of closed-mindedness is always an intellectual vice; rather I treat the analysis of the disposition, and its (...) status as an intellectual vice, as separate questions. The concluding section develops a framework for determining the conditions under which closed-mindedness will be an intellectual vice. (shrink)

Animal welfare is a concept that plays a role within both our moral deliberations and the relevant areas of science. The study of animal welfare has impacts on decisions made by legislators, producers and consumers with regards to housing and treatment of animals. Our ethical deliberations in these domains need to consider our impact on animals, and the study of animal welfare provides the information that allows us to make informed decisions. This thesis focusses on taking a philosophical perspective to (...) answer the question of how we can measure the welfare of animals. Animal welfare science is an applied area of biology, aimed at measuring animal welfare. Although philosophy of animal ethics is common, philosophy focussing on animal welfare science is rare. Despite this lack, there are definitely many ways in which philosophical methods can be used to analyse the methodologies and concepts used in this science. One of the aims of the work in this thesis is to remedy this lack of attention in animal welfare. Animal welfare science is a strong emerging discipline, but there is the need for conceptual and methodological clarity and sophistication in this science if it is to play the relevant informative role for our practical and ethical decision-making. There is thus is a strong role here for philosophical analysis for this purpose. The central aim of this thesis is to provide an account of how we can measure subjective animal welfare, addressing some of the potential problems that may arise in this particular scientific endeavour. The two questions I will be answering are: what is animal welfare, and how do we measure it? Part One of the thesis looks at the subjective concept of animal welfare and its applications. In it, I argue for a subjective welfare view - that animal welfare should be understood as the subjective experience of individuals over their lifetimes - and look at how the subjective welfare concept informs our ethical decision-making in two different cases in applied animal ethics. Part Two of the thesis looks more closely at the scientific role of welfare. Understanding welfare subjectively creates unique measurement problems, due to the necessarily private nature of mental states and here I address a few of these problems, including whether subjective experience is measurable, how we might validate indicators of hidden target variables such as welfare, how we can make welfare comparisons between individual animals and how we might compare or integrate the different types of experience that make up welfare. I end with a discussion of the implications of all these problems and solutions for the practice of welfare science, and indicate useful future directions for research. (shrink)

Is closed-mindedness always an intellectual vice? Are there conditions in which it might be an intellectual virtue? This paper adopts a working analysis of closed-mindedness as an unwillingness or inability to engage seriously with relevant intellectual options. In standard cases, closed-mindedness will be an intellectual vice. But, in epistemically hostile environments, closed-mindedness will be an intellectual virtue.

In this paper I argue that the way to reduce the power of overdemanding beauty ideals is not to advocate that individuals have a ‘duty to resist’, a duty to stop engaging in appearance enhancing practices and body work. I begin by arguing against the claim that women who ‘do’ beauty are suffering from false consciousness. I then give four further additional arguments against advocating a ‘duty to resist’ as an effective means to challenge dominant beauty norms. First, that as (...) a tactic it is ineffective. Second, it is an individual approach which divides and silences. Third, it induces shame and blame, and undermines effective collective action. Fourth, it fails to recognize the privilege of the group norms which make resistance possible. (shrink)

In this essay, we discuss Simona Ginsburg and Eva Jablonka’s The Evolution of the Sensitive Soul from an interdisciplinary perspective. Constituting perhaps the longest treatise on the evolution of consciousness, Ginsburg and Jablonka unite their expertise in neuroscience and biology to develop a beautifully Darwinian account of the dawning of subjective experience. Though it would be impossible to cover all its content in a short book review, here we provide a critical evaluation of their two key ideas—the role of Unlimited (...) Associative Learning in the evolution of, and detection of, consciousness and a metaphysical claim about consciousness as a mode of being—in a manner that will hopefully overcome some of the initial resistance of potential readers to tackle a book of this length.

_In _Teaching for Purpose_, Heather Malin explores the idea of purpose as the purpose of education and shows how educators can prepare youth to live intentional, fulfilling lives._ The book highlights the important role that purpose—defined as “a future-directed goal that is personally meaningful and aimed at contributing to something larger than the self”—plays in optimal youth development and in motivating students to promote the cognitive and noncognitive skills that teachers want to instill. Based on a decade of research (...) conducted at the Stanford University Center on Adolescence, the book explores how educators and schools can promote purpose through attention to school culture, curriculum, project learning, service learning, and other opportunities. Malin argues for expansive thinking on the direction schools should take, especially in terms of educating students to be creative, innovative, and self-directed critical thinkers. The book includes profiles of six organizations working in schools across the US that have made purpose development a priority. Infused with the engaging voices of purposeful youth, _Teaching for Purpose_ offers a fresh, inspirational guide for educators who are looking for new ways to support students to succeed not only in school, but in life.

Digital data is an increasing and continual presence across the sites, activities and relationships of everyday life. In this article we explore what data presence means for the ways that the everyday is organised, sensed, and anticipated. While digital data studies have demonstrated how data is deeply entangled with the way in which everyday life is lived out and valued, at the same time our relationships with data are riddled with anxieties or small niggles or tricky trade-offs and their use (...) is often chaotic and muddled, part of the inevitable uncertainty about what will happen next. If the presence of data is part of the environments we inhabit, this raises the question of how and why data is valuable to us and what forms of hope and trust enable this value to further develop.

With increasing attention given to wild animal welfare and ethics, it has become common to depict animals in the wild as existing in a state dominated by suffering. This assumption is now taken on board by many and frames much of the current discussion; but needs a more critical assessment, both theoretically and empirically. In this paper, we challenge the primary lines of evidence employed in support of wild animal suffering, to provide an alternative picture in which wild animals may (...) often have lives that are far more positive than is commonly assumed. Nevertheless, while it is useful to have an alternative model to challenge unexamined assumptions, our real emphasis in this paper is the need for the development of effective methods for applying animal welfare science in the wild, including new means of data collection, the ability to determine the extent and scope of welfare challenges and opportunities, and their effects on welfare. Until such methods are developed, discussions of wild animal welfare cannot go beyond trading of intuitions, which as we show here can just as easily go in either direction. (shrink)

All athletes experience victory and defeat, but how many truly learn from the experience of sport? For ancient Greek philosophers, sport was an integral part of education. Today, athletics programs remain in schools, but we face a growing gap between the modern sports experience and enduring educational values. This book seeks to bridge that gap by advocating a philosophical approach to the sports experience. Combining issues and ideas from traditional philosophy with contemporary analyses of sport and applied "thinking activities," this (...) book invites athletes to learn about life from their experience of sport. The text works its way from internal reflection to social interaction by addressing four important topics: self-discovery, responsibility, respect, and citizenship. This sequence is important because authentic self-knowledge is an essential foundation for effectively dealing with the personal and social challenges faced by philosophical athletes. Reid discusses specific issues such as violence, racism, and performance-enhancing drugs in their relevant contexts, although philosophical athletes focus on the big picture, approaching each issue from a complete vision of themselves, their moral commitments, and their social roles. Athletes as diverse as the teenage college recruit and the aging weekend-warrior will gain insight into their sports experience and into their lives. This philosophical approach maximizes what we can learn from sport and gives us the best chance for leading better lives because of it. (shrink)

Introduction to Education provides pre-service teachers with an overview of the context, craft and practice of teaching in Australian schools as they commence the journey from learner to classroom teacher. Each chapter poses questions about the nature of teaching students, and guides readers though the Australian Professional Standards for Teachers. Incorporating recent research and theoretical literature, Introduction to Education presents a critical consideration of the professional, policy and curriculum contexts of teaching in Australia. The book covers theoretical topics in chapters (...) addressing assessment, planning, safe learning environments, and working with colleagues, families, carers and communities. More practical chapters discuss professional experience and building a career after graduation. Rigorous in conception and practical in scope, Introduction to Education welcomes new educators to the theory and practical elements of teaching, learning, and professional practice. (shrink)

After raising some minor philosophical points about Kevin Elliott’s A Tapestry of Values (2017), I argue that we should expand on the themes raised in the book and that philosophers of science need to pay as much attention to the loom of science (i.e., the institutional structures which guide the pursuit of science) as the tapestry of science. The loom of science includes such institutional aspects as patents, funding sources, and evaluation regimes that shape how science gets pursued, and that (...) attending to these aspects will enable us to provide more robust guidance on the values that infuse the tapestry of science.

The performance of natural behavior is commonly used as a criterion in the determination of animal welfare. This is still true, despite many authors having demonstrated that it is not a necessary component of welfare –some natural behaviors may decrease welfare, while some unnatural behaviors increase it. Here I analyze why this idea persists, and what effects it may have. I argue that the disagreement underlying this debate on natural behavior is not one about which conditions affect welfare, but a (...) deeper conceptual disagreement about what the state of welfare actually consists of. Those advocating natural behavior typically take a “teleological” view of welfare, in which naturalness is fundamental to welfare, while opponents to the criterion usually take a “subjective” welfare concept, in which welfare consists of the subjective experience of life by the animal. I argue that as natural functioning is neither necessary nor sufficient for understanding welfare, we should move away from the natural behavior criterion to an alternative such as behavioral preferences or enjoyment. This will have effects in the way we understand and measure welfare, and particularly in how we provide for the welfare of animals in a captive setting. (shrink)

What is a virtue, and how are virtues different from vices? Do people with virtues lead better lives than the rest of us? Do they know more? Can we acquire virtues if so, how? In this lively and engaging introduction to this core topic, Heather Battaly argues that there is more than one kind of virtue. Some virtues make the world a better place, or help us to attain knowledge. Other virtues are dependent upon good intentions like caring about (...) other people or about truth. Virtue is an original approach to the topic, which carefully situates the fields of virtue ethics and virtue epistemology within a general theory of virtue. It argues that there are good reasons to acquire moral and intellectual virtues virtuous people often attain greater knowledge and lead better lives. As well as approaching virtue in a novel and illuminating way, Battaly ably guides the reader through the dense literature surrounding the topic, deftly moving from important specific and technical points to more general issues and questions. The final chapter proposes strategies for helping university students acquire intellectual virtues. Battaly’s insights are complemented by entertaining examples from popular culture, literature, and film, really bringing this topic to life for readers. Virtue is the ideal introduction to the topic. It will be an equally vital resource for students who are encountering the topic for the first time, and for scholars who are deeply engaged in virtue theory. (shrink)

Douglas proposes a new ideal in which values serve an essential function throughout scientific inquiry, but where the role values play is constrained at key points, protecting the integrity and objectivity of science.

Much of the discussion of Naive Realism about veridical experience has focused on a consequence of adopting it—namely, disjunctivism about perceptual experience. However, the motivations for being a Naive Realist in the first place have received relatively little attention in the literature. In this paper, I will elaborate and defend the claim that Naive Realism provides the best account of the phenomenal character of veridical experience.

This book presents a new theory of the relationship between vagueness, context-sensitivity, gradability, and scale structure in natural language. Heather Burnett argues that it is possible to distinguish between particular subclasses of adjectival predicatesDLrelative adjectives like tall, total adjectives like dry, partial adjectives like wet, and non-scalar adjectives like hexagonalDLon the basis of how their criteria of application vary depending on the context; how they display the characteristic properties of vague language; and what the properties of their associated orders (...) are. It has been known for a long time that there exist empirical connections between context-sensitivity, vagueness, and scale structure; however, a formal system that expresses these connections had yet to be developed. This volume sets out a new logical system, called DelTCS, that brings together insights from the Delineation Semantics framework and from the Tolerant, Classical, Strict non-classical framework, to arrive at a full theory of gradability and scale structure in the adjectival domain. The analysis is further extended to examine vagueness and gradability associated with particular classes of determiner phrases, showing that the correspondences that exist between the major adjectival scale structure classes and subclasses of determiner phrases can also be captured within the DelTCS system.

De-extinction is the process through which extinct species can be brought back into existence. Although these projects have the potential to cause great harm to animal welfare, discussion on issues surrounding de-extinction have focussed primarily on other issues. In this paper, I examine the potential types of welfare harm that can arise through de-extinction programs, including problems with cloning, captive rearing and re-introduction. I argue that welfare harm should be an important consideration when making decisions on de-extinction projects. Though most (...) of the proposed benefits of these projects are insufficient to outweigh the current potential welfare harm, these problems may be overcome with further development of the technology and careful selection of appropriate species as de-extinction candidates.

Contemporary philosophy of perception is dominated by extremely polarized debates. The polarization is particularly acute in the debate between naïve realist disjunctivists and their opponents, but divisions seem almost as stark in other areas of dispute (for example, the debate over whether we experience so-called ‘high-level’ properties, and the debate concerning individuation of the senses). The guiding hypothesis underlying this volume is that such polarization stems from insufficient attention to how we should go about settling these debates. In general, there (...) is widespread, largely implicit disagreement concerning what philosophical theories of perception are supposed to explain, the claims that we should hold fixed in the course of theorizing, and the methods that such theorizing should employ. The goal of this volume is to move such methodological questions from the background to the fore, in the hope of facilitating progress. The contributions constitute an initial effort to spur more explicit, systematic discussion of methodology in philosophy of perception. They cover a wide range of relevant topics, from the relation between scientific and philosophical theorizing about perception, to lessons we can learn from the history of philosophy of perception.

This article uses Marc Lewis’ work as a springboard to discuss the socio-political context of the brain disease model of addiction. The claim that promotion of the BDMA is the only way the general public can be persuaded to withhold blame and punishment from addicts is critically examined. After a discussion of public understandings of the disease concept of addiction, it is pointed out that it is possible to develop a scientific account of addiction which is neither a disease nor (...) a moral model but which the public could understand. Evidence is reviewed to suggest that public acceptance of the disease concept is largely lip-service and that the claim the BDMA removes stigma among the public and professionals is unsupported by evidence. Further, there is good evidence that biogenetic explanations of mental/behavioural disorders in general have been counterproductive in the attempt to ally stigma. A model of addiction as a disorder of choice may attract special problems in public-facing communications and risks being misunderstood. However, ways of presenting this model to the public are suggested that may avoid such risks. Lastly, the claim that the BDMA is the only way of ensuring access to treatment and of maintaining research funding for addiction is disputed and a way in which these benefits can be retained under a disorder-of-choice model proposed. The article concludes by enthusiastically endorsing Lewis’ call for a third stage in the governing image of addiction. (shrink)

One of the biggest problems in applications of animal welfare science is our ability to make comparisons between different individuals, both within and across species. Although welfare science provides methods for measuring the welfare of individual animals, there’s no established method for comparing measures between individuals. In this paper I diagnose this problem as one of underdetermination—there are multiple conclusions given the data, arising from two sources of variation that we cannot distinguish: variation in the underlying target variable (welfare experience) (...) and in the relationship of measured indicators to the target. I then describe some of the possible methods of making comparisons, based on the use of similarity assumptions that will have greater or lesser justification in different circumstances, and the alternative methods we may use when direct comparisons are not possible. In the end, all our available options for making welfare comparisons are imperfect, and we need to make explicit context-specific decisions about which will be best for the task at hand while acknowledging their potential limitations. Future developments in our understanding of the biology of sentience will help strengthen our methods of making comparisons. (shrink)
