As Hume famously claimed, we are nowhere more free than in our imagination. While this feature of imagination suggests that imagination has a crucial role to play in modal epistemology, it also suggests that imagining cannot provide us with any non-modal knowledge about the world in which we live. This chapter rejects this latter suggestion. Instead it offers an account of “imagining under constraints,” providing a framework for showing when and how an imaginative project can play a justificatory role with (...) respect to our beliefs about the world. That we can be free in our imaginings does not show that they must proceed unfettered; as is argued, our ability to constrain our imaginings in light of facts about the world enables us to learn from them. The important upshot is that imagination has considerably more epistemic significance than previously thought. (shrink)

Though philosophers such as Wittgenstein and Sartre have dismissed imagination as epistemically irrelevant, this chapter argues that there are numerous cases in which imagining can help to justify our contingent beliefs about the world. The argument proceeds by the consideration of case studies involving two particularly gifted imaginers, Nikola Tesla and Temple Grandin. Importantly, the lessons that we learn from these case studies are applicable to cases involving less gifted imaginers as well. Though not all imaginings will have justificatory power, (...) the chapter shows how the sorts of cases in which imagining plays an epistemic role can be easily distinguished from the sorts of cases in which it does not.

In “The Standing to Blame: A Critique” (2013), Macalester Bell challenges theories that claim that ‘standing’ plays a central role in blaming practices. These standard accounts posit that it is not enough for the target of blame to be blameworthy; the blamer also must have the proper standing to blame the wrongdoer. Bell identifies and criticizes four different standing conditions, (1) the Business Condition, (2) the Contemporary Condition, (3) the Nonhypocricy Condition, and (4) the Noncomplicity Condition. According to standard accounts, (...) these conditions must be met in order for a would-be blamer to properly blame a wrongdoer. In this paper, I defend the Business Condition against Bell’s critique. My argument, then, is that some version of the standard account survives and ‘standing’ should be part of our theory of properly-wielded blame. I conclude by raising two additional concerns regarding the agency of blamers and the possibility that, without proper standing, a blamer could make things worse. (shrink)

Drawing on a landscape analysis of existing data-sharing initiatives, in-depth interviews with expert stakeholders, and public deliberations with community advisory panels across the U.S., we describe features of the evolving medical information commons. We identify participant-centricity and trustworthiness as the most important features of an MIC and discuss the implications for those seeking to create a sustainable, useful, and widely available collection of linked resources for research and other purposes.

Morally supererogatory actions are traditionally conceived of as actions that are nonobligatory but distinctively morally worthy. Here I challenge the assumption that supererogatory actions are distinctively praiseworthy and offer an alternative definition of moral supererogation. This alternative definition complements, and is complemented by, a novel account of moral praiseworthiness, which I call the Two-Step view. My Two-Step view of moral worth, which I develop in some detail, accounts for currently underappreciated features of moral praiseworthiness.

In this essay I explore how travel and border-crossing for abortion care constitutes a challenge to methodological nationalism, which serves to obscure such experiences from view. Drawing up field research conducted at two abortion clinics in Albuquerque, New Mexico, I also explore some implications of regarding pregnant people who travel for abortion care as a type of migrant, even if they are U.S. citizens and legal residents. Finally, I assess how this discursive shift can make important contributions to pandemic and (...) migration ethics. (shrink)

In this paper, we explore the perspectives of expert stakeholders about who owns data in a medical information commons and what rights and interests ought to be recognized when developing a governance structure for an MIC. We then examine the legitimacy of these claims based on legal and ethical analysis and explore an alternative framework for thinking about participants' rights and interests in an MIC.

According to a widely shared notion, music is not only something that we can understand, but moreover something that gives us access to a specific form of cognitive reflection. This paper suggests that the first part of this notion is only plausible if musical understanding is not explained in terms of grasping the meaning of music, but in terms of experiencing its sense. Music has neither a classifiable meaning full content nor a predicative structure, both of which are necessary in (...) order for a medium of reflection. Therefore, the second part of this notion can only be defended in a rather modest way, insofar as the cognitive function of music is limited to its role merely as a means that serves our otherwise language-based reflexive competence.

Ich versuche zu zeigen, dass sich der Prozess des ästhetischen Erfahrens als einer des verstehenden Nachvollzugs begreifen lässt, in dem wir die mit Erlebnisqualitäten verbundenen Wahrnehmungen (beispielsweise einer Melodie) auf einer grundlegenden Ebene mittels der Erlebnisqualitäten anderer Wahrnehmungen (beispielsweise einer Geste) strukturieren; und zwar so, dass wir den Gegenstand dieses Verstehens als eine Einheit erfassen. Es zeigt sich dabei zum einen, dass sich Verstehen nicht im begrifflichen Erfassen von Bedeutungen, Handlungen oder Ursache- Wirkungs-Relationen erschöpft; und zum anderen, dass uns in (...) Gestalt des Nachvollziehens eine Form des Verstehens offensteht, der die Möglichkeit innewohnt, uns selbst und anderen Aspekte unseres subjektiven Erlebens (des Gegenstands) bewusst zu machen und begrifflich zu artikulieren. Die Philosophie des Geistes muss sich daher der Aufgabe stellen, das Verhältnis zwischen phänomenalen und intentionalen Aspekten unseres Geistes produktiver zu erläutern als bloß in Formeiner Disjunktion. I will try to show that the process of making an aesthetic experience can be conceived as a process of understanding via re-enactment in which we structure the phenomenal qualities of perceptions (e.g. of a melody) at a fundamental level by means of the phenomenal qualities of other perceptions (e.g. of a gesture); and this in such a way that we grasp the object of this understanding as a unity. Thereby, it turns out that understanding is not restricted to conceptually grasping meanings, actions, or relations of cause and effect. Moreover, re-enactment shows itself as a form of understanding, which enables us to become aware of aspects of our subjective experience, to make others understand these aspects, and to articulate them conceptually. hilosophy of mind must therefore face the task of elucidating the relationship between phenomenal and intentional aspects of our mind in a more productive way than in the form of a mere disjunction.

This article examines the productive capacity of emotion through the concept of emotional fundamentalism. Emotional fundamentalism combines several key concepts—fundamentalism, affective labor, biopolitics, and capitalism’s contradictions—developed by Michael Hardt and Antonio Negri in Empire, Multitude, and Commonwealth to describe the intensified attention to the body in education. I investigate the implications of the increased organizational and corporate interest in emotion using an ongoing socio-emotional learning study and the introduction of artificial intelligence aggression detectors in schools. Doing so demonstrates the tendency (...) of Empire to manage emotions in order to ensure viable production by educating the body as data and human capital. However, though Empire depends on emotions as a resource, these same emotions display a creative unruliness that exposes potential avenues to reproduce the common and enact multitude. (shrink)

This paper advocates for the inclusion of patient perspectives in the diagnosis and treatment of eating disorders (EDs) for ethical, epistemological, and pragmatic reasons. We build upon the ideas of a recent editorial published in this journal. Using EDs as their example, the authors argue against dominant DSM-oriented approaches in favor of an increased focus on understanding patients’ subjective experiences. We argue that their analysis stops too soon for the development of practical—and actionable—insights into how to effect the integration of (...) first-person and third-person accounts of EDs. Methods Contextual analysis was used to make the case for patient perspectives. (shrink)

This essay considers the dependency of trans youth by bridging transgender studies with feminist care ethics to emphasize a trans wisdom about solidarity through dependency. The first major section of the essay argues for reworking Sara Ruddick's philosophy of mothering in the context of trans and gender‐creative youth. This requires, first, stressing a more robust interaction among her divisions of preservative love, nurturance for growth, and training for acceptability, and second, creating a more nuanced account of “nature” in relation to (...) nurturance for growth to avoid casting transition as contrary to a trans youth's healthy development. In the second major section of the essay, I depart from Ruddick's framework to emphasize the difference of care for trans youth by trans and/or queer communities and through mutual caregiving, stressing a trans wisdom about dependency and solidarity found in the work of Sylvia Rivera and Marsha P. Johnson. Turning to Eva Feder Kittay's links between dependency work and equality, I argue that Rivera and Johnson's work contains a distinct knowledge derived from practice necessitating the connection between solidarity and dependency in particular communities. I then call for more work on trans care ethics, trans ethics, and trans wisdom more broadly. (shrink)

Scholars addressing the moral status of corporations are motivated by a pair of conflicting anxieties: If corporations are not moral agents, we will be unable to blame them for their wrongs. But if corporations are moral agents, we will have to recognize corporate moral rights, and the legal rights that flow therefrom. In early and under-appreciated work, Tom Donaldson sought to allay both concerns at once: Corporations, he argued, are not moral persons, and so are not eligible for many of (...) the rights that persons enjoy; but they are moral agents, and so ought to bear responsibility in many of the ways that persons do. This article offers a sympathetic critique of the Donaldsonian strategy. I argue that, as it has been elaborated, the strategy necessarily fails. Nonetheless the strategy embodies a worthy aim and so I seek to provide an alternative way to vindicate it. (shrink)

This interdisciplinary book examines the work of several female artists since 1960 in the areas of dance, music, installation, photography, architecture, poetry, literature, theater, film, and performance art. Each chapter is primarily devoted to an important work by a single artist, seen within its historical context, and with particular attention to how each artist incorporated gender issues or feminist thought into her respective art form. Laurie Anderson, Gwendolyn Brooks, Jane Campion, Judy Chicago, Zaha Hadid, Pauline Oliveros, Yvonne Rainer, Cindy Sherman, (...) Amy Tan, and Paula Vogel have each made groundbreaking contributions to their fields. As a group, they represent a tremendous diversity of approaches to art making: from accessible to opaque, from overtly feminist to apolitical, from emotive to cool, from controversial to mainstream.

Why do laws and regulations marking boundaries between humans and other animals proliferate amid widespread proclamations of the waning of the species concept and the consensus that life is a continuum? Here I consider a recent spate of new guidelines and regulations in the United Kingdom and United States that work to estrange human bodies from other animals in biomedicine. Using the idea of a bioconstitutional moment to understand how state institutions deliberate over “human–animal chimeras,” I address how nations differently (...) establish separations between humans and other animals. New chimeric entities, containing human hereditary material, have consecrated regulatory ground and signify increased attention to fields of research that have long used interspecies mixing. Regulators and policy makers now find themselves in a curious position. On the one hand, they continue to regulate the estrangement between humans and other animals, but on the other, they support the creation of chimeric life––a form of life that draws into question the very basis of such separations.

Certain kinds of prediction, foreknowledge, and future‐oriented action appear to require settled future truths. But open futurists think that the future is metaphysically unsettled: if it is open whether p is true, then it cannot currently be settled that p is true. So, open futurists—and libertarians who adopt the position—face the objection that their view makes rational action and deliberation impossible. I defuse the epistemic concern: open futurism does not entail obviously counterintuitive epistemic consequences or prevent rational action.

I offer a new, limited solution to divine hiddenness based on a particular epistemic paradox: sometimes, knowing about a desired outcome or relevant features of that desired outcome would prevent the outcome in question from occurring. I call these cases epistemically self-defeating situations. This solution, in essence, says that divine hiddenness or silence is a necessary feature of at least some morally excellent or desirable states of affairs. Given the nature of the paradox, an omniscient being cannot completely eliminate hiddenness, (...) just as an omnipotent being cannot create a rock so heavy that they cannot lift it. Epistemically self-defeating situations provide an undercutting defeater for the assumption that any nonresistant nonbeliever could always, at any time, be in conscious relationship with a perfectly loving God. Thankfully, silence is a temporary feature of epistemically self-defeating situations: once the outcome is achieved, agents can know in full. (shrink)

Two years ago, a nest box outside my window held a pair of Violet-Green Swallow. I counted six swallows fledge from the box and take their first flights in the July rain. Leaving the roof of the nest box, they flew in little loops out over the water, trying out their wings. I watched them from the dock, their bodies suspended in the air between the raindrops. This experience was the inspiration for what I call ‘nest-works’ – for poetic wilding (...) of all-too-human spaces. Nest-works began with an experimental panel for the 2021 College Art Association Conference, called ‘Co-Making this World’. The experimental session was modelled after the nest of a bird, a Black-Capped Chickadee. As this cavity-nester builds a home of disparate materials, the panel of artist-researchers built a session of disparate theories and practices, as we considered relationships with world-systems that are in the process of making (such as the nest of the chickadee). For Technoetic Arts, we weave a new nest-work of research material, as we consider new models for knowledge and creative production. This nest-work is an entanglement of short essays made by artists working with a common pattern, framing eco-poetics on collaborative and participatory processes with the non-human/more-than-human.

A substantial portion of biomedical R&D is publicly funded. But resulting medicines are typically covered by patents held by private firms, and priced without regard to the public’s investment. The Bayh-Dole Act provides a possible remedy, but its scope is limited.

This article explores a perplexing line from Rousseau's Emile: his suggestion that the ‘most important rule’ for the educator is ‘not to gain time but to lose it’. An analysis of what Rousseau meant by this line, the article argues, shows that Rousseau provides the philosophical groundwork for a radical critique of the contemporary cultural framework that supports homework, standardised testing, and the competitive extracurricular activities that consume children's time. He offers important insights to contemporary parents and educators wishing to (...) reimagine an educational system that is currently fuelled more by familial and international amour propre than by children's interests and needs. Not the least of these is his recognition that to reimagine children's education would require a new configuration of the very terms of modern life. Problematically, however, Rousseau's alternative to mechanised clock-time depends on the labour of Sophie, whose time is also reconfigured. For the next generation of children to be educated according to natural time, Sophie's labour needs to be off the clock too, which is just as much a linchpin of her removal from the public sphere of citizenship and the paid workforce as it is of Emile's education for public life, or so the final section of this paper argues.

Taxonomy and terminology might seem like dull topics. But the diverse ways that eighteenth-century philosophers identified and classified the emotions crucially shaped the approaches they took. This chapter traces the sources available to eighteenth-century British philosophers for naming and ordering the passions, lays out the main vocabulary and concepts used for description and analysis, including the notions of “reflection” and “sympathy,” and outlines the principles that organized explanation, such as the division of the passions into the pleasurable or painful, and (...) the selfish or social, as well as the role of “master passions.”.

This article is a co-written reflection on the process of curating and programming Printing Solidarity: Tricontinental Graphics from Cuba (2021–2022). Held at Stony Brook University's Paul W. Zuccaire Gallery, the exhibition featured over sixty posters and printed matter produced mostly in the 1960s–1970s by the Organization of Solidarity with the People of Asia, Africa, and Latin America (OSPAAAL) in Havana. As an experiment in pedagogical curating, the yearlong project spanned the isolation from, return to, and re-envisioning of inperson learning during (...) the COVID-19 pandemic. Reflecting on our inspirations, intentions, and challenges, we argue for the role of art objects in activating material-based, in-person learning on campus and consider the value of academic collaboration, cross-regional research, and experimental pedagogies. The project offered an opportunity to revisit the Cold War-period politics of global solidarity in today's pandemic era while exploring what it would mean to study art today from the question of solidarity rather than division.

Abstract. The American dream of the “self-made man” is as central to the functioning of our capitalist society as Wall Street and as familiar as the Statue of Liberty. According to this dream, the tired masses have a shot at making it on their own if they have the will power, stamina, and intestinal fortitude to survive and compete. What do we do now that we are faced with scientific evidence that this very strategy is driving society into disconnection, despair, (...) and even poor health? Relational-cultural theory states that growth happens through and toward relationships not toward increased separation and autonomy. Relational-cultural theory describes empathy and mutuality as key components to healthy relationships. This essay will focus on the latest research in the neuroscience of relationships—the development of the capacity to connect within relationships, the systems that help us read and empathize with others, the adaptability and plasticity of the central nervous system, and the destructive nature of isolation.

Considerable interest has long existed in two separate phenomena of considerable social interest, namely children’s early exposure to employment outside of any organizational, legislative, or collective bargaining protection, and teenage smoking. We used data from a large national survey to address possible direct and indirect links between children’s early employment intensity and smoking because of significant long-term implications of the link between work and well-being in a vulnerable population. Fifth to ninth grade children’s informal employment intensity was related to both (...) smoking history and smoking intent, and these effects were partially mediated by the amount of weekly spending money and self-esteem. The number of one’s parents and friends who smoke separately moderated the relationships between self-esteem and weekly spending money, and smoking behavior. These findings illustrate the complex consequences of young children’s exposure to early employment, and emphasize the need for research on the ethical implications of pre- and early teenagers who are employed outside of the formal employment context.

_Psychology's Grand Theorists_ argues that the three schools in psychology that have been dominant historically--the psychodynamic, behavioral, and phenomenological--have resulted in large part from the personal experiences of their originators. Sigmund Freud, B.F. Skinner, and Carl Rogers each believed that he had discovered the truth about human nature, yet their truths are entirely different. This book explores how the lives of these men influenced the divergent theories they developed, through a close examination of letters, diaries, biographies, autobiographies, and professional writings. (...) Uncovering the subjective sources of these theories, the book gives the reader a greater sense of intimacy with each man's ideas, and promotes critical inquiry into their scientific status. The book is written in an engaging style that will appeal to a wide range of readers. Intended as a supplement in courses on personality, clinical psychology, and/or the history of psychology, it will also be of interest to clinicians or counselors who use one or more of these theoretical models in their therapeutic work.

On December 30, 2003, the FDA announced that it will publish a rule banning sales of ephedra - a dietary supplement often utilized for weight loss, increased energy, and enhanced athletic performance - because it poses an unreasonable health risk.The ban will be issued under the auspices of the Federal Food, Drug, and Cosmetic Act and the Dietary Supplement Health and Education Act of 1994, in response to a process that began in June of 1997, when the FDA first proposed (...) a mandatory warning statement on dietary supplements containing ephedra.

In this article, I argue that the material and rhetorical connection between “parental involvement” and motherhood has the effect of making two important features of parental involvement disappear. Both of these features need to be taken into account to think through the positive and negative effects of parental involvement in public schooling. First, parental involvement is labor. In the following section of this paper, I discuss the work of feminist scholars who have brought this to light. Second, parental involvement remains (...) one of the most significant ways in which citizens participate in the public sphere. While education reform projects centered on parental involvement do show some recognition that what parents/mothers do is in fact work, even as they ignore the gendered dimensions of this work and sunnily demand that parents do ever more of it, these projects resist the recognition that parents’/mothers’ involvement is also political.

This paper provides a framework, based on Peircean pragmatism and a supplemental metaphysical principle, for reconciling realism and antirealism. Peircean polymorphism, the resultant position defended in the paper, is a realist position, accepting that there is a world that exists and has characteristics of its own, independently of our experience of it. The position denies, however, what I call the uniqueness assumption about truth -- that it is possible for one, unique representational approach to adequately represent reality. While Peirce does (...) not explicitly address the uniqueness assumption, his account is sufficiently ambiguous on this point to have been understood as a uniqueness account. The supplemental metaphysical principle introduced here, that reality is polymorphic, serves to fortify Peirce's pragmatism against uniqueness. Briefly, the paper outlines some implications of accepting the fortified Peircean position, including greater explanatory power and more compelling motivation for continued scientific inquiry.

Although Nietzsche scholars have paid close attention to his aphoristic and rhetorical style, few have focused on his practice of writing prefaces. In this paper, I engage in a close reading of Nietzsche’s prefaces and identify five themes present in his earlier and later prefaces: (1) he speaks directly to his readers, (2) he stresses the necessity of slow and careful reading, (3) he encourages readers to trust themselves, (4) he refers to himself as a herald, and (5) he uses (...) combative and polemical language to describe his work. Given these themes, I conclude that Nietzsche’s preface writing project constitutes a practice of self-care as described by Foucault in “Technologies of the Self” and “The Ethics of the Concern for Self as a Practice of Freedom.”.

Drawing on my experiences at a teaching-focused university, I show how locating the health humanities in first-year or introductory composition courses improves learning and offers an economical, flexible, and far-reaching approach to bringing a health humanities education to all baccalaureate-level learners, regardless of whether they aspire to careers in the health professions. In terms of improving learning, health humanities composition courses support the disciplinary aims of both fields. Accessible, relevant issues in the health humanities, such as interventions in health debates (...) or representations of illness and healthcare settings, nourish the cognitive and social conditions needed to develop college-level writing skills. The health humanities’ emphases on interdisciplinarity and suspending judgment also inform students’ writing abilities. Composition trains students to write rhetorically by considering purpose, context, genre, mode, and other factors when addressing an audience. This approach to writing helps pre-health humanists communicate intentionally and compassionately about health topics as well as the larger issues they call into question. Because students enroll in health humanities composition courses at an early, formative moment in their studies, they are poised to carry or “transfer” their knowledge to other courses, including those that might prepare them for the workforce.

Since the beginning of the twentieth century in the Spanish Basque Country, Basque nationalism has served as a unifying movement that encouraged women to participate in women’s associations. Women’s associations offered a metaspace in which public and private spheres overlap, where, women began to reconstruct meanings of nationalism and gender relations in distinct ways. As a result, the particular foci of these associations reflected each individual association’s specific understanding of gender relations and their relations to different interpretations of Basque nationalism. (...) This historical tradition has continued into the twenty-first century as women’s associations that are structured by distinct systems of gender relations provide a number of social services and educational services to promote gender equality. Through the examination of the metaspace of the women’s association Lanbroa, this article explores the ways in which the women’s movement and feminism have influenced the functioning of this association and the ways in which association members contest traditional Basque gender relations.

Much of the most substantive and in‐depth experience with formal cost‐benefit analysis in the public policy realm has occurred in the context of federal environmental regulation in the United States. This experience has many important lessons to teach in the realm of synthetic biology. Indeed, many of the dangers and pitfalls that arise when decision‐makers use formal CBA to evaluate environmental regulation seem likely to arise in the synthetic biology context as well, sometimes in particularly troubling forms. Unfortunately, while in (...) many instances these concerns may well point toward a rejection of formal CBA for synthetic biology, the experience from environmental regulation turns out to be far less helpful in identifying alternative decision‐making tools. Because the decisions that arise in the synthetic biology context have a fundamentally different structure from decisions about environmental regulation, the most useful alternatives from that context do not map easily onto this new context.It may well be generally true that in the search for decision‐making tools, we should not be looking for a single silver bullet that will work in all public policy realms. Perhaps, instead, different kinds of decision‐making call for different tools. This may be true even within the realm of synthetic biology. I am not entirely sure what the “right” tool is for synthetic biology applications, or even whether a “right” tool exists. But at the end of this essay, I offer a few tentative thoughts about why scenario analysis—a strategic planning tool first developed in the context of military planning following World War II—might be one alternative worth considering.

This study investigates: the changes in three major health-related factors—physical activity, non-physical-activity health behavior, and depressive symptoms, and how changes in physical activity were associated with changes in one’s depressive symptoms among young adults, middle-aged adults, and older adults while controlling non-physical-activity health behavior and sociodemographic characteristics among young, middle-aged, and older adults before and after the COVID-19 outbreak lockdown in the United States. A total of 695 participants completed an online questionnaire via MTurk, and participants were asked to recall (...) their physical activity, depressive symptoms, and non-physical-activity health behavior status in January and May of 2020. The IPAQ-SF was used to evaluate individuals’ physical activity, while the CES-D-10 was used to assess depressive symptoms. Covariates included non-physical-activity health behavior and sociodemographic factors. A Bayesian significance testing of changes was used to examine significant changes in physical activity, non-physical-activity behavior, and depressive symptoms in each age group while Bayesian regression analysis was employed to examine how the changes in physical activity were associated with respondents’ depressive symptoms while controlling for individual NHB and sociodemographic characteristics. The results showed that the participants tended to maintain their physical activity levels after the lockdown despite significant increases in sitting time among young and older adults. Decreases in moderate physical activity frequency were associated with a higher level of depressive symptoms. Although young and middle-aged cohorts experienced fewer differences in depressive symptoms compared to their counterparts in the older group, we found no significant heterogeneity effects in the relationships of interest across all age groups. Considering different influences of physical activity on depressive symptoms depending on different levels of activity and ages, more randomized clinical trials with program-based intervention studies should be conducted with different physical activity programs for different age populations.
