SummaryRecently discovered documents have revealed the background to a letter published in The Darwin Correspondence, dated 21 February 1838 and sent to Charles Darwin and six others from John George Children of the British Museum. It concerned a complaint made by Edward Blyth about George Robert Gray, assistant in charge of birds at the museum. A response by Darwin, and 14 other referees, supported Gray's defence of his character, and the complaint was dismissed. It is concluded that Children investigated this (...) complaint so vigorously because of recent criticism of the natural history collections by witnesses to the Select Committee of the House of Commons on the British Museum (1836–37), who sought to increase the involvement and influence of career scientists in the overseeing of the collections. Children may have also been sensitive to criticism because he was a controversial appointee. (shrink)

Astronauts often report experiences of awe and wonder while traveling in space. This paper addresses the question of whether awe and wonder can be scientifically investigated in a simulated space travel scenario using a neurophenomenological method. To answer this question, we created a mixed-reality simulation similar to the environment of the International Space Station. Portals opened to display simulations of Earth or Deep Space. However, the challenge still remained of how to best capture the resulting experience of participants. We could (...) use psychological methods, neuroscientific methods or philosophical methods. Each of these approaches offer many benefits, but each is also limited. Neurophenomenology capitalises on and integrates all three methods. We employed questionnaires from psychology, electroencephalography, electrocardiography, and functional near-infrared spectroscopy from neuroscience, and a phenomenological interview technique from philosophy. This neurophenomenological method enabled extensive insight in experiencers and non-experiencers of awe and wonder in a simulated space scenario that otherwise would not have been possible. Traditional empirical analyses were completed, followed by individual differences analyses using interview transcriptions paired with physiological responses. Experiencers of AW showed differences in theta and beta activity throughout the brain compared to non-experiencers. Questionnaires indicated that non-experiencers of AW gave more positive responses of religious and spiritual practices than experiencers of AW. Interviews showed that awe and wonder were more likely to occur when watching the simulated Earth view instead of the Deep Space view. Our study is a successful example of neurophenomenology, a powerful and promising interdisciplinary approach for future studies of complex states of experience. (shrink)

Frequency effects are pervasive in studies of language, with higher frequency words being recognized faster than lower frequency words. However, the exact nature of frequency effects has recently been questioned, with some studies finding that contextual information provides a better fit to lexical decision and naming data than word frequency ( Adelman et al., 2006 ). Recent work has cemented the importance of these results by demonstrating that a measure of the semantic diversity of the contexts that a word occurs (...) in provides a powerful measure to account for variability in word recognition latency ( Johns et al., 2012, 2015 ; Jones et al., 2012 ). The goal of the current study is to extend this measure to examine bilingualism and aging, where multiple theories use frequency of occurrence of linguistic constructs as central to accounting for empirical results ( Gollan et al., 2008 ; Ramscar et al., 2014 ). A lexical decision experiment was conducted with four groups of subjects: younger and older monolinguals and bilinguals. Consistent with past results, a semantic diversity variable accounted for the greatest amount of variance in the latency data. In addition, the pattern of fits of semantic diversity across multiple corpora suggests that bilinguals and older adults are more sensitive to semantic diversity information than younger monolinguals.

Childhood adversity is associated with altered or dysregulated stress reactivity; these altered patterns of physiological functioning persist into adulthood. Evidence from both preclinical animal models and human neuroimaging studies indicates that early life experience differentially influences stressor-evoked activity within central visceral neural circuits proximally involved in the control of stress responses, including the subgenual anterior cingulate cortex (sgACC), paraventricular nucleus of the hypothalamus (PVN), bed nucleus of the stria terminalis (BNST) and amygdala. However, the relationship between childhood adversity and the (...) resting-state connectivity of this central visceral network remains unclear. To this end, we examined relationships between childhood threat and childhood socioeconomic deprivation, the resting-state connectivity between our regions of interest (ROIs), and affective symptom severity and diagnoses. We recruited a transdiagnostic sample of young adult males and females (n= 100; mean age = 27.28,SD= 3.99; 59 females) with a full distribution of maltreatment history and symptom severity across multiple affective disorders. Resting-state data were acquired using a 7.2-min functional magnetic resonance imaging (fMRI) sequence; noted ROIs were applied as masks to determine ROI-to-ROI connectivity. Threat was determined by measures of childhood traumatic events and abuse. Socioeconomic deprivation (SED) was determined by a measure of childhood socioeconomic status (parental education level). Covarying for age, race and sex, greater childhood threat was significantly associated with lower BNST-PVN, amygdala-sgACC and PVN-sgACC connectivity. No significant relationships were found between SED and resting-state connectivity. BNST-PVN connectivity was associated with the number of lifetime affective diagnoses. Exposure to threat during early development may entrain altered patterns of resting-state connectivity between these stress-related ROIs in ways that contribute to dysregulated neural and physiological responses to stress and subsequent affective psychopathology.

Otto Neugebauer’s early academic career was marked by a series of transitions. His interests shifted from physics to mathematics, and finally to the history of ancient mathematics and exact sciences. Yet even from his early years in Graz, Neugebauer was strongly attracted to the mathematical culture of Göttingen. When he arrived there in 1922, he quickly established a strong personal friendship with Richard Courant, the newly appointed Director of the Mathematics Institute. Neugebauer and Courant worked together closely up until 1933, (...) when the Nazi government decimated the Göttingen scientific community. In this essay, Neugebauer’s historical work and his vision for a new approach to the study of the exact sciences are viewed through the prism of these events. By so doing, one can easily appreciate how Neugebauer’s scholarship reflects the ideals he and Courant shared as leading representatives of the Göttingen mathematical tradition. (shrink)

Experiential evidence shows that pain is associated with common meanings. These include a meaning of threat or danger, which is experienced as immediately distressing or unpleasant; cognitive meanings, which are focused on the long-term consequences of having chronic pain; and existential meanings such as hopelessness, which are more about the person with chronic pain than the pain itself. This interdisciplinary book - the second in the three-volume Meanings of Pain series edited by Dr Simon van Rysewyk - aims to better (...) understand pain by describing experiences of pain and the meanings these experiences hold for the people living through them. The lived experiences of pain described here involve various types of chronic pain, including spinal pain, labour pain, rheumatic pain, diabetic peripheral neuropathic pain, fibromyalgia, complex regional pain syndrome, endometriosis-associated pain, and cancer-related pain. Two chapters provide narrative descriptions of pain, recounted and interpreted by people with pain. Language is important to understanding the meaning of pain since it is the primary tool human beings use to manipulate meaning. As discussed in the book, linguistic meaning may hold clues to understanding some pain-related experiences, including the stigmatisation of people with pain, the dynamics of patient-clinician communication, and other issues, such as relationships between pain, public policy and the law, and attempts to develop a taxonomy of pain that is meaningful for patients. Clinical implications are described in each chapter. This book is intended for people with pain, their family members or caregivers, clinicians, researchers, advocates, and policy makers. (shrink)

The U.S. National Institute of Allergies and Infectious Diseases and the National Institute of Mental Health have a new research priority: inclusion of terminally ill persons living with HIV in HIV cure-related research. For example, the Last Gift is a clinical research study at the University of California San Diego for PLWHIV who have a terminal illness, with a prognosis of less than 6 months. As end-of-life HIV cure research is relatively new, the scientific community has a timely opportunity to (...) examine the related ethical challenges. Following an extensive review of the EOL and HIV cure research ethics literature, combined with deliberation from various stakeholders and our experience with the Last Gift study to date, we outline considerations to ensure that such research with terminally ill PLWHIV remains ethical, focusing on five topics: 1) protecting autonomy through informed consent, 2) avoiding exploitation and fostering altruism, 3) maintaining a favorable benefits/risks balance, 4) safeguarding against vulnerability through patient-participant centeredness, and 5) ensuring the acceptance of next-of-kin/loved ones and community stakeholders. EOL HIV cure-related research can be performed ethically and effectively by anticipating key issues that may arise. While not unique to the fields of EOL or HIV cure-related research, the considerations highlighted can help us support a new research approach. We must honor the lives of PLWHIV whose involvement in research can provide the knowledge needed to achieve the dream of making HIV infection curable. (shrink)

BackgroundThe pursuit of a cure for HIV is a high priority for researchers, funding agencies, governments and people living with HIV (PLWH). To date, over 250 biomedical studies worldwide are or have been related to discovering a safe, effective, and scalable HIV cure, most of which are early translational research and experimental medicine. As HIV cure research increases, it is critical to identify and address the ethical challenges posed by this research.MethodsWe conducted a scoping review of the growing HIV cure (...) research ethics literature, focusing on articles published in English peer-reviewed journals from 2013 to 2021. We extracted and summarized key developments in the ethics of HIV cure research. Twelve community advocates actively engaged in HIV cure research provided input on this summary and suggested areas warranting further ethical inquiry and foresight via email exchange and video conferencing.DiscussionDespite substantial scholarship related to the ethics of HIV cure research, additional attention should focus on emerging issues in six categories of ethical issues: (1) social value (ongoing and emerging biomedical research and scalability considerations); (2) scientific validity (study design issues, such as the use of analytical treatment interruptions and placebos); (3) fair selection of participants (equity and justice considerations); (4) favorable benefit/risk balance (early phase research, benefit-risk balance, risk perception, psychological risks, and pediatric research); (5) informed consent (attention to language, decision-making, informed consent processes and scientific uncertainty); and (6) respect for enrolled participants and community (perspectives of people living with HIV and affected communities and representation).ConclusionHIV cure research ethics has an unfinished agenda. Scientific research and bioethics should work in tandem to advance ethical HIV cure research. Because the science of HIV cure research will continue to rapidly advance, ethical considerations of the major themes we identified will need to be revisited and refined over time. (shrink)

Alexander Pruss’s Principle of Sufficient Reason states that every contingent true proposition has an explanation. Pruss thinks that he can plausibly maintain both his PSR and his account of libertarian free will. This is because his libertarianism has it that contingent true propositions reporting free choices are self-explanatory. But I don’t think Pruss can plausibly maintain both his PSR and libertarianism without a rift occurring in one or the other. Similar to the old luck/randomness objection, I contend that Pruss’s libertarianism (...) is susceptible to what I call “the inexplicability objection”, which attempts to show that agents’ free choices involve contingent brute facts. Pruss may be able to partially explain a proposition such that Jones freely chose A for reason R, but he cannot adequately explain a contrastive proposition such as that Jones freely chose A for R rather than B for R*. The result is that either PSR is too explanatorily permissive for libertarianism, or libertarianism is too explanatorily impermissive to satisfy PSR. After considering what I take to be Pruss’s best response to the inexplicability objection, I conclude that his attempt to reconcile PSR and libertarianism is unsuccessful. (shrink)

The essays in Religious Upbringing and the Costs of Freedom are the personal stories of philosophers who were brought up religiously and have broken free, in one way or another, from restraint and oppression. As trained philosophers, they are well equipped to reflect on and analyze their experiences. In this book, they offer not only stories of stress and liberation but ruminations on the moral issues that arise when parents and other caregivers, in seeking to do good by their children, (...) sometimes end up doing real harm to their personal development and sense of autonomy as individuals. In addition to the editors, the contributors are Raymond D. Bradley, Damien Alexander DuPont, Diane Enns, Paul H. Hirst, Amalia Jiva, Irfan Khawaja, Christine Overall, Tasia R. Persson, and Glen Pettigrove. (shrink)

This article considers a range of responses to Plato's Symposium, paying particular attention to Diotima's speech on eros and philosophy. It argues that Diotima's teachings contain resources for a relational pedagogy, but that these resources come more sharply into focus when Plato's text is read through the lens of contemporary (20th and 21st century) thinkers. The article therefore draws on the work of David Halperin, Hannah Arendt, Jean-François Lyotard and Luce Irigaray to argue that Diotima points us towards the value (...) of educative encounters as reciprocal and unpredictable events of initiation and becoming. Diotima's rhetorical emphasis on birth is shown to be especially important for refiguring pedagogical relations in terms of natality, understood as a capacity for new beginnings, and hence for reclaiming education as a potentially generative encounter, rather than one governed by the logic of reproduction. The final section of the article turns to work by Christine Battersby, bell hooks, Richard Smith and Morwenna Griffiths to resituate the discussion in relation to questions of autonomy. As a corrective to the modern bias towards the value of the autonomous individual, it argues that dependencies and unequal power relations can be a constitutive and enabling aspect of the educative process. Attention to such relations should thus form a key part of a relational pedagogy. (shrink)

Nishida Kitaro, originator of the Kyoto School and 'father of Japanese Philosophy' is usually viewed as an essentially apolitical thinker who underwent a 'turn' in the mid-1930s, becoming an ideologue of Japanese imperialism. Political Philosophy in Japan challenges the view that a neat distinction can be drawn between Nishida's apolitical 'pre-turn' writings and the apparently ideological tracts he produced during the war years. In the context of Japanese intellectual traditions, this book suggests that Nishida was a political thinker form the (...) very beginning of his career, and consequently, his later political works cannot be dismissed as peripheral to his philosophical project. Counter-intuitively however, Christopher Goto-Jones argues that a consistently political reading of his philosophy reveals a dissenting standpoint even during the height of the Pacific War. This book argues that the prevailing postwar tendency to dismiss interwar and wartime Japanese culture as fascist or ultra nationalist en total neglects a lively political discourse, which contained some serous and profound political insight and even dissent. By suggesting that Nishida tetsugaku was a voice of dissent during Japan's Great East Asia War, Goto-Jones presents a case for the rehabilitation of Nishida as a political thinker, and as an example of a Japanese resistance, able to make a valuable contribution to contemporary debates about international political, globalization , and inter-cultural relations. Offering a unique and potentially controversial view of the subject of Nishida and the Kyoto School, The Political Philosophy of Japan will be of huge interest to anyone studying Japanese History, Political Philosophy and comparative philosophy alike.

Call a bit of scientific discourse a description of a missing system when (i) it has the surface appearance of an accurate description of an actual, concrete system (or kind of system) from the domain of inquiry, but (ii) there are no actual, concrete systems in the world around us fitting the description it contains, and (iii) that fact is recognised from the outset by competent practitioners of the scientific discipline in question. Scientific textbooks, classroom lectures, and journal articles abound (...) with such passages; and there is a widespread practice of talking and thinking as though there are systems which fit the descriptions they contain perfectly, despite the recognition that no actual, concrete systems do so—call this the face value practice. There are, furthermore, many instances in which philosophers engage in the face value practice whilst offering answers to epistemological and methodological questions about the sciences. Three questions, then: (1) How should we interpret descriptions of missing systems? (2) How should we make sense of the face value practice? (3) Is there a set of plausible answers to (1) and (2) which legitimates reliance on the face value practice in our philosophical work, and can support the weight of the accounts which are entangled with that practice? In this paper I address these questions by considering three answers to the first: that descriptions of missing systems are straightforward descriptions of abstract objects, that they are indirect descriptions of “property-containing” abstracta, and that they are (in a different way) indirect descriptions of mathematical structures. All three proposals are present in the literature, but I find them wanting. The result is to highlight the importance of developing a satisfactory understanding of descriptions of missing systems and the face value practice, to put pressure on philosophical accounts which rely on the practice, and to help us assess the viability of certain approaches to thinking about models, theory structure, and scientific representation.

Feminism and Ecological Communities presents a bold and passionate rethinking of teh ecofeminist movement. It is one of the first books to acknowledge the importance of postmodern feminist arguments against ecofeminism whilst persuasively preseenting a strong new case for econolocal feminism. Chris J.Cuomo first traces the emergence of ecofeminism from the ecological and feminist movements before clearly discussing the weaknesses of some ecofeminist positions. Exploring the dualisms of nature/culture and masculing/feminine that are the bulwark of many contemporary ecofeminist positions and (...) questioning traditional traditional feminist analyses of gender and caring, Feminism and Ecological Communities asks whether women are essentially closer to nature than men and how we ought to link the oppression of women, people of colour, and other subjugated groups to the degradation of nature. Chris J.Cuomo addresses these key issues by drawing on recent work in feminist ethics as well as teh work of diverse figures such as Aristotle, John Dewey, Donna Haraway adn Maria Lugones. A fascinating feature of the book is the use of the metaphor of the cyborg to highlight the fluidity of the nature/culture distinction and how this can enrich econfeminist ethics and politics. An outstanding new argument for an ecological feminism that links both theory and practice, Feminism and Ecological Communities bravely redraws the ecofeminist map. It will be essential reading for all those interested in gender studies, environmental studies and philosophy. (shrink)

The concept of moral distress comes from nursing ethics, and was initially defined as ‘…when one knows the right thing to do, but institutional constraints make it nearly impossible to pursue the right course of action’. There is a large body of literature associated with moral distress, yet multiple definitions now exist, significantly limiting its usefulness. We undertook a systematic review of the argument-based bioethics literature on this topic as the basis for a critical appraisal, identifying 55 papers for analysis. (...) We found that moral distress is most frequently framed around individual experiences of distress in relation to local practices and constraints, and understood in terms of power relations and workplace hierarchies. This understanding is directly derived from, and often still seen as specific to, nursing. Frequently the perspective of the morally distressed individual is privileged. Understandings of moral distress have evolved towards an ‘occupational health approach’, with the assumption that moral distress should be measured and prevented. Counter-perspectives were identified, highlighting conceptual problems. Based on our review, we propose a redefinition of moral distress: ‘Ethical unease or disquiet resulting from a situation where a clinician believes they have contributed to avoidable patient or community harm through their involvement in an action, inaction or decision that conflicts with their own values’. This definition is specific enough for research use, anchored in clinicians’ professional responsibilities and concerns about harms to patients, framed relationally rather than hierarchically, and amenable to multiple perspectives on any given morally distressing situation.

Despite extinction-based processes demonstrating efficacy in the animal extinction and human anxiety literatures, extinction for substance use disorders has shown poor efficacy. Reasons for this lack of success include common threats to extinction, such as renewal and reinstatement. In recent decades, research on mindfulness for SUD has flourished, and a key aspect of these mindfulness-based interventions includes teaching individuals to stay present with whatever experience they have, even if unpleasant, without trying to change/escape/avoid it. Similarly, CET teaches individuals to not (...) escape/avoid conditioned responses by engaging in drug use behavior. This paper discusses how mindfulness-based research and practices could positively influence CET through future research, with the long-term goal of improving SUD treatment. (shrink)

Despite rich theoretical development, empirical research on stakeholder management is scant, save its relationship with financial performance. Recent research shows significant intrafirm variability in stakeholder management across time. This study seeks to explain why firms would experience significant changes in stakeholder management. Adapting Wood’s framework to discuss three principles of stakeholder management, the authors identify antecedents of change at the institutional, organizational, and executive levels. Pressures for legitimacy at the institutional level suggest that firm age and size, along with industry (...) shifts in stakeholder management, will increase the likelihood of changes in stakeholder management for the focal firm. The authors posit that organizational risk and performance will also affect the likelihood of change, as will managerial discretion, ownership, and succession. The authors test their predictions using a longitudinal sample of stakeholder management data and discuss the implications of the findings for research and practice. (shrink)

The idea of dignity is often taken to be a foundation for principles of justice and democracy. In the West it has numerous formulations and conceptualisations. Within the capabilities approach to justice theorists have expanded the concept of dignity to encompass animals and ecological communities. In this article I rework the idea of dignity to include the Māori philosophical concepts of Mauri, tapu and mana – something I argue is necessary if the capabilities approach is to decolonise in the Aotearoa (...) context. Furthermore, the article links the nation’s recognition of three extensive geographical regions – Te Awa Tupua, Te Urewera and Mt Taranaki – as legal persons to Mātauranga Māori and nonhuman dignity. In doing so, I identify the potential that this understanding of dignity and these legal moves have to decolonise democracy within the settler state. (shrink)

Personal autonomy is often taken to consist in self-government or self-determination. Personal autonomy thus seems to require self-control. However, there is reason to think that autonomy is compatible with the absence of self-control. Akratic action, i.e., action performed against the agent’s better judgement, can be free. And it is also plausible to think that free actions require autonomy. It is only when you determine what you do yourself that you act freely. It follows that akratic actions can be autonomous. At (...) least in some cases, it is the agent herself, and not some alien part of her, who determines her akratic actions. But akratic actions are usually thought to be paradigm cases of self-control failure. Thus, we have reason both to conclude that autonomy requires self-control and that autonomy is compatible with the absence of self-control. My aim is to discuss the main solutions to this paradox.

Research has shown that a majority of employed women experience sexual harassment and suffer negative repercussions because of it; yet only a minority of these women label their experiences “sexual harassment.” To investigate how people identify sexual harassment, in-depth interviews were conducted with 18 waitpeople in restaurants in Austin, Texas. Most respondents worked in highly sexualized work environments. Respondents labeled sexual advances as sexual harassment only in four specific contexts: when perpetrated by someone who exploited their powerful position for personal (...) sexual gain; when the perpetrator was of a different race/ethnicity than the victim—typically a minority man harassing a white woman; when the perpetrator was of a different sexual orientation than the victim—typically a gay man harassing a straight man; or when violence or the threat of violence was used. The authors argue that the hegemonic norms of acceptable sexual activity privilege heterosexual relationships, legitimize institutionalized forms of sexual exploitation in the workplace, and may protect assailants of the same race and sexual orientation as their victims from charges of sexual harassment.

Nine years into the tumultuous life of Hong Kong as a special Administrative Region of the People’s Republic of China, it has become clearer what role Hong Kong plays in China’s modernization. This paper argues that Hong Kong’s role is that of a transforming catalyst. In dealing with the affairs of this city, Beijing from time to time has to put aside its normal instincts. This creates opportunities with potentially far-reaching consequences for the nation as a whole even though questions (...) have often been raised as to whether “two systems” will survive as Hong Kong becomes more integrated into “one China.” Hong Kong’s plight is difficult and there are constant risks of being overwhelmed by the much larger mainland system. Nevertheless, just looking at what may be seen as Hong Kong’s losses in the process of integration will prevent a deeper examination of how the mainland has been affected at the same time. Hong Kong presents Beijing with many challenging issues as well that go to the core of party ideology and practices. This is not to say that Beijing intends Hong Kong to be a pacesetter for political reform on the mainland, but at least in one corner of the country where debates are in the open and where the people’s behavior is different, the result is that Hong Kong has a gradual transforming effect on China’s modernization by forcing deliberation, debate, and possibly even behavioral change on some of the most sensitive issues to the Chinese leadership.

Conscience is the psychological faculty by which we aware of and respond to the moral character of our own actions. It is most commonly thought of as the source of pains we suffer as a result of doing what we believe is wrong --- the pains of guilt, or “pangs of conscience.” It may also be seen, more controversially, as the source of our knowledge of what is right and wrong, or as a motive for moral conduct. Thus a person (...) who is motivated to act on principle is said to act “conscientiously.” These terms come from the Latin “conscientia,” a direct translation of the Greek “syneidesis.” This ranges in meaning from being aware of something to “knowing something in common with” someone. Knowing something in common with someone can mean sharing his secret, and this puts you in a position to serve as a witness against him. Thus the term came to have a judicial use, to describe one who could bear witness. In certain contexts, “syneidesis” came to mean a state of knowing in common with oneself, and so of bearing witness against oneself. Although these terms appear in Stoic and Epicurean works, conscience did not receive extensive philosophical treatment until the Medieval period, when treatises on conscience became standard. Medieval philosophers distinguished two aspects of conscience, “conscientia” and “synderesis.” Roughly, “synderesis” refers to the ineradicable and infallible basis of conscience in human nature, while “conscientia” refers to the more particular judgments we make about our actions. There are various ways of specifying the two ideas further. In Thomas Aquinas’s account, which became standard, synderesis grasps the basic moral principles which are the first premises of practical reasoning, while conscientia is the conclusion, the act of judging that one ought to perform a particular action.

In this paper I argue that the ground of this disagreement is different than philosophers have traditionally supposed. On the surface, the disagreement appears to be a matter of substantive moral judgment: Hume admires the sort of person who rushes to the aid of another from motives of sympathy or humanity, while Kant thinks that a person who helps with the thought that it is his duty is the better character. While a moral disagreement of this kind certainly follows from (...) their views, I will argue that the source of the disagreement lies elsewhere, namely in their different conceptions of action and motivation. This difference leads in turn to a surprisingly deep difference in their conception of our relation to other people, and of what it means to interact with other people. It is his conception of human interaction that leads Hume to think that benevolence is natural while there is something artificial about our motives to act justly and to keep our promises. For Kant, on the other hand, no form of adult human motivation is “natural” in Hume’s sense – all adult human motivation involves the agent’s use of nonnatural concepts such as law or reason. But Kant’s theory of interaction grounds another sense in which it is just as “natural” to be motivated to keep our promises and agreements as it is to be motivated to help each other out when we are in need.
