Recent defences of abortion on demand have located the morally relevant difference between normal adult human beings and non-viable fetuses in the possession of personhood by the former but not by the latter. It is, so the story goes, morally wrong to kill innocent human beings because they are persons, but non-viable fetuses, though they be biologically human, are nevertheless not persons and may therefore be killed without doing anything morally wrong.

We argue in this essay that any society that organizes itself to punish criminals should in justice consider itself strictly liable to punish only those who are guilty in fact of the crimes for which they are punished. We argue that justice, not utility, is the basis of the obligation society has not to punish the innocent and that any society that is just would bind itself by statute to compensate the innocents it punishes by mistake. We hope to have (...) made it evident that when the justice of criminal punishment is the issue justice and strict liability are not incompatible; rather, we hope to have shown that one does not understand the nature of justice unless one recognizes that society is strictly liable and therefore owes compensation when, through no fault of its own, it punishes the innocent.

Schools may be one important context where adolescents learn and shape the behaviors necessary for promoting global inclusivity in adulthood. Given the importance of bystanders in halting bullying and peer aggression, the focus of this study is on both moral judgments regarding one type of bullying, social exclusion, and factors that are associated with bystander intervention. The study includes 896 adolescents, who were 6th, and 9th graders, approximately evenly divided by gender. Participants were primarily European–American. Results revealed that girls and (...) participants who perceived better relationships between students and teachers were more likely to judge exclusion to be wrong. Further, ethnic minority participants, those who were more anxious about being rejected by their teachers and reported more teacher discrimination were less likely to judge exclusion as wrong. Participants who reported more positive student–teacher relationships, perceptions of a more positive school social environment and more prior experiences of teacher discrimination were more likely to report that they would seek help for the victim. On the other hand, participants who reported being more angry about teacher rejection, experiencing either peer or teacher discrimination, and perceiving they are excluded from opportunities at school were less likely to intervene to come to the aid of a peer who is being excluded. The results document the complex interplay of school and teacher factors in shaping adolescents’ bystander responses to social exclusion. Our findings suggest that positive school climate can promote intentions to intervene. However, findings indicate that adolescents who are marginalized in their school environments, and who report experiences of rejection, exclusion or discrimination are not willing or likely to intervene to prevent others from experiencing exclusion.

Interest in science and math plays an important role in encouraging STEM motivation and career aspirations. This interest decreases for girls between late childhood and adolescence. Relatedly, positive mentoring experiences with female teachers can protect girls against losing interest. The present study examines whether visitors to informal science learning sites differ in their expressed science and math interest, as well as their science and math stereotypes following an interaction with either a male or female educator. Participants were visitors to one (...) of four ISLS in the United States and United Kingdom. Following an interaction with a male or female educator, they reported their math and science interest and responded to math and science gender stereotype measures. Female participants reported greater interest in math following an interaction with a female educator, compared to when they interacted with a male educator. In turn, female participants who interacted with a female educator were less likely to report male-biased math gender stereotypes. Self-reported science interest did not differ as a function of educator gender. Together these findings suggest that, when aiming to encourage STEM interest and challenge gender stereotypes in informal settings, we must consider the importance of the gender of educators and learners.

Meat is a multi-billion-dollar industry that relies on people performing risky physical work inside meat-processing facilities over long shifts in close proximity. These workers are socially disempowered, and many are members of groups beset by historic and ongoing structural discrimination. The combination of working conditions and worker characteristics facilitate the spread of SARS-CoV-2, the virus that causes COVID-19. Workers have been expected to put their health and lives at risk during the pandemic because of government and industry pressures to keep (...) this “essential industry” producing. Numerous interventions can significantly reduce the risks to workers and their communities; however, the industry’s implementation has been sporadic and inconsistent. With a focus on the U.S. context, this paper offers an ethical framework for infection prevention and control recommendations grounded in public health values of health and safety, interdependence and solidarity, and health equity and justice, with particular attention to considerations of reciprocity, equitable burden sharing, harm reduction, and health promotion. Meat-processing workers are owed an approach that protects their health relative to the risks of harms to them, their families, and their communities. Sacrifices from businesses benefitting financially from essential industry status are ethically warranted and should acknowledge the risks assumed by workers in the context of existing structural inequities.

Previous research has demonstrated that reversing the contrast of the eye region, which includes the eyebrows, affects the N170 ERP. To selectively assess the impact of just the eyes, the present study evaluated the N170 in response to reversing contrast polarity of just the iris and sclera in upright and inverted face stimuli. Contrast reversal of the eyes increased the amplitude of the N170 for upright faces, but not for inverted faces, suggesting that the contrast of eyes is an important (...) contributor to the N170 ERP.

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

In 2005, Charles Mills published “‘Ideal Theory’ as Ideology” in Hypatia: a withering critique of much of contemporary political philosophy and ethics. For Mills such work in philosophy failed to attend to the realities of social life and politics, and in remaining silent on actual issues of domination and oppression served an ideological role in supporting the interests of white bourgeois men. Around the time that Charles Mills launched his broadside against ideal theory, trans theorists had been fighting their own (...) battle against the abstraction of theory from the realities of trans lives and oppression. Vivian Namaste (2000) and Jay Prosser (1998) argued that contemporary gender theory failed to justice to the actuality of trans life, retreating instead to understanding trans life through literary archetypes and idealized radical figures. In this chapter I’ll compare Mills’ critique of ideal theory with the transfeminist critique of 1990s gender theory, arguing that they share much in common. Centrally, both critiques share an underlying commitment to theory needing to be grounded in the actuality of oppression and power relations. This common thread, I suggest, must continue to guide transfeminist thought and action: contra Marquis Bey (2022) transfeminist thought and praxis must continue to be about trans lives, about the oppression of trans women, and about ways of actually achieving liberation from our current dire position.

Does a flourishing life involve pursuing passionate attachments? Can we choose what these passionate attachments will be? This book offers an original theory of how we can actively cultivate our passionate attachments. The author argues that not only do we have reason to view passionate attachments as susceptible to growth, change, and improvement, but we should view these entities as amenable to self-cultivation. He uses Pierre Hadot's and Michel Foucault's accounts of Hellenistic self-cultivation as vital conceptual tools to formulate a (...) theory of cultivating our passionate attachments. First, their accounts offer the conceptual resources for a philosophical theory of how we can cultivate our passionate attachments. Second, the exercises of self-cultivation they focus on allow us to outline a practical method though which we can cultivate our passionate character. Doing this brings out a significantly new dimension to the role of the passionate attachments in the flourishing life and offers theoretical and practical accounts of how we can cultivate them based on the Hellenistic conception of self-directed character change. Cultivating Our Passionate Attachments will be of interest to advanced students and scholars working in virtue ethics, moral philosophy, and ancient philosophy. (shrink)

Ron Giere’s recent book Scientific perspectivism sets out an account of science that attempts to forge a via media between two popular extremes: absolutist, objectivist realism on the one hand, and social constructivism or skeptical anti-realism on the other. The key for Giere is to treat both scientific observation and scientific theories as perspectives, which are limited, partial, contingent, context-, agent- and purpose-dependent, and pluralism-friendly, while nonetheless world-oriented and modestly realist. Giere’s perspectivism bears significant similarity to earlier ideas of Paul (...) Feyerabend and John Dewey. Comparing these to Giere’s work not only uncovers a consilience of ideas, but also can help to fill out Giere’s account in places where it is not fully developed, as well as helping us understand the work of these earlier authors and their continuing relevance to contemporary concerns in philosophy of science.Keywords: Ronald Giere; Paul Feyerabend; John Dewey; Perspectivism; Pragmatism; Pluralism.

In this chapter I focus on two problems facing immigration systems around the world, and Australia in particular. The topics addressed are chosen because each one involves important fundamental rights and because significant improvement in these areas is possible even if each state acts alone, without significant coordination with others. First, I examine refugee programmes, focussing specifically on the ‘two- tier’ refugee programmes pioneered by Australia with the introduction of Temporary Protection Visas by the Howard Government in 1999. Next, I (...) look at recent declines in refugee resettlement schemes from already stingy levels and, in relation to Australia in particular, I show how the tying of resettlement numbers to the number of affirmative asylum claims granted is both wrong- headed and counterproductive. The second area of immigration policy explored is family migration, another area where immigration systems around the world have been moving in the wrong direction, often via less than transparent administrative processes. Australia is no exception. While Australia’s family migration system is reasonably good on its face, in practice there are several factors which make the programme significantly less than satisfactory from the perspective of protecting the basic rights of migrants and, arguably more importantly, citizens. These problems can and should be fixed in straightforward ways, and since doing so would be more just, would have few— if any— significant negative consequences, and in fact would have a number of clear benefits, those changes should be made.

During his more than fifty-year writing and teaching career, Horace M. Kallen (1882-1974), the American Jewish philosopher who coined the term "cultural pluralism," incorporated into his pragmatism-infused philosophy of life a number of different sciences, from racial science to psychology and physics. Part biography, part cultural history, "Horace Kallen Confronts America" offers fresh insight into the larger question of how social discourses shape modern American Jewish identity.

Ageing causes progressive decline in metabolic, behavioural, and physiological functions, leading to a reduced health span. The extracellular matrix (ECM) is the three‐dimensional network of macromolecules that provides our tissues with structure and biomechanical resilience. Imbalance between damage and repair/regeneration causes the ECM to undergo structural deterioration with age, contributing to age‐associated pathology. The ECM ‘Ageing Across the Life Course’ interdisciplinary research network (ECMage) was established to bring together researchers in the United Kingdom, and internationally, working on the emerging field (...) of ECM ageing. Here we report on a consultation at a joint meeting of ECMage and the Medical Research Council / Versus Arthritis Centre for Integrated Research into Musculoskeletal Ageing, held in January 2023, in which delegates analysed the key questions and research opportunities in the field of ECM ageing. We examine fundamental biological questions, enabling technologies, systems of study and emerging in vitro and in silico models, alongside consideration of the broader challenges facing the field.

‘Gender disappointment’ is regularly reported by those whose child’s sex does not match the sex that they, the parent, desired. With symptoms ranging from mere fleeting sadness to documented cases of serious depression, alienation from one’s child, and emotional suffering, it is clear that so-called ‘gender disappointment’ is a serious issue, that has, as yet, seen little philosophical attention (though see Hendl and Browne 2020). In this chapter I explore gender disappointment, not from the perspective of a parent who ended (...) up with the child of the wrong sex at birth, but rather, from the perspective of a different kind of gender disappointment: the transgender person who grew up and only then disappointed their parents by turning out to be the ‘wrong’ gender. This perspective, I argue, reveals a great deal about the shared gender essentialism at the heart of patriarchal and cissexist ideology. Moreover, I will argue that it reveals the underlying propertarian relationship of parents to their children under contemporary capitalism – a troubling relationship that legitimates the treatment of children as objects to be designed and controlled as commodities at the whims of parents. In this way I disagree with Whyman when he writes that “a preference for having a child of one sex over the other should be considered one of those irrational things of which some sense can nevertheless be made – like aesthetic taste” (Whyman 2021, 113-114). I argue, to the contrary, that the desire for a child of one particular gender is not akin to a mere unproblematic aesthetic preference. Instead, and following the rich feminist tradition of thinking about the patriarchal origins of sexual desire, I argue that we must see these desires as troubling reflections of dominant patriarchal and cissexist ideology, underwritten by a particular neoliberal capitalist mode of production. Moreover, we can seek to change those desires. (shrink)

What does it mean to consider the world of AI through a Christian lens? Rapid developments in AI continue to reshape society, raising new ethical questions and challenging our understanding of the human person. Encountering Artificial Intelligence draws on Pope Francis’ discussion of a culture of encounter and broader themes in Catholic social thought in order to examine how current AI applications affect human relationships in various social spheres and offers concrete recommendations for better implementation. The document also explores questions (...) regarding personhood, consciousness, and the kinds of relationships humans might have with even the most advanced AI. Through these discussions, this book investigates the theoretical and practical challenges to interpersonal encounter raised by the age of AI.

"What is gender? More importantly, what should gender look like in the 21st century? This book brings together philosophy with insights from feminist and transgender theory to argue for a position called 'ameliorative pluralism' about gender: that there should be more than two genders, and that each gender term should have multiple meanings. Matthew Cull argues that we should be pluralists about gender, developing and arguing for a position that more apt for contemporary transgender and feminist activism. The 21st (...) century requires a new way of thinking about gender. What Gender Should Be sets out to provide it"--. (shrink)

It is widely accepted that ethical leadership is beneficial for the organization, the leader, and followers. Yet, little has been said about potential limitations of ethical leadership, particularly boundary conditions involving the same person perceived to display ethical leadership. Drawing on conservation of resources theory, we argue that supervisor-induced hindrance stress and job hindrance stress are factors linked to the supervisor and work environment that may limit the positive impact of ethical leadership on employee deviance and turnover intentions. Specifically, we (...) expect that high levels of hindrance stress drain resources, specifically perceptions of social support, by inhibiting the completion of work, particularly in combination with the high expectations of ethical leaders. We test our model across two time-lagged field studies. Our results demonstrate that supervisor-induced hindrance stress mitigates some of the beneficial impact of ethical leadership and that job hindrance stress further strains these relationships. Overall, our results suggest that both forms of hindrance stress jointly impact the effectiveness of ethical leadership on important outcomes, and do so partly because of their influence on perceived social support. We discuss theoretical contributions to the ethical leadership and stress bodies of literature, as well as practical implications for managers and organizations wishing to develop ethical leaders.

Asylum has become a highly charged political issue across developed countries, raising a host of difficult ethical and political questions. What responsibilities do the world's richest countries have to refugees arriving at their borders? Are states justified in implementing measures to prevent the arrival of economic migrants if they also block entry for refugees? Is it legitimate to curtail the rights of asylum seekers to maximize the number of refugees receiving protection overall? This book draws upon political and ethical theory (...) and an examination of the experiences of the United States, Germany, the United Kingdom and Australia to consider how to respond to the challenges of asylum. In addition to explaining why asylum has emerged as such a key political issue in recent years, it provides a compelling account of how states could move towards implementing morally defensible responses to refugees.

The idea that science is or should be value-free, and that values are or should be formed independently of science, has been under fire by philosophers of science for decades. Science and Moral Imagination directly challenges the idea that science and values cannot and should not influence each other. Matthew J. Brown argues that science and values mutually influence and implicate one another, that the influence of values on science is pervasive and must be responsibly managed, and that science (...) can and should have an influence on our values. This interplay, he explains, must be guided by accounts of scientific inquiry and value judgment that are sensitive to the complexities of their interactions. Brown presents scientific inquiry and value judgment as types of problem-solving practices and provides a new framework for thinking about how we might ethically evaluate episodes and decisions in science, while offering guidance for scientific practitioners and institutions about how they can incorporate value judgments into their work. His framework, dubbed "the ideal of moral imagination," emphasizes the role of imagination in value judgment and the positive role that value judgment plays in science. (shrink)

Proponents of the value ladenness of science rely primarily on arguments from underdetermination or inductive risk, which share the premise that we should only consider values where the evidence runs out or leaves uncertainty; they adopt a criterion of lexical priority of evidence over values. The motivation behind lexical priority is to avoid reaching conclusions on the basis of wishful thinking rather than good evidence. This is a real concern, however, that giving lexical priority to evidential considerations over values is (...) a mistake and unnecessary for avoiding the wishful thinking. Values have a deeper role to play in science. (shrink)

Drawing on social comparison theory, we investigate employees’ ethical and performance comparisons relative to a similar coworker and subsequent emotional and behavioral responses. We test our theoretically driven hypotheses across two studies. Study 1, a cross-sectional field study, reveals that employees who perceive they are more ethical than their coworkers experience negative emotions toward the comparison coworkers and those feelings are even stronger when the employees perceive they are lower performers than their coworkers. Results also reveal that negative emotions mediate (...) the indirect relationship between being more ethical than a coworker, but also being a lower performer than that coworker onto social undermining and ostracism. Study 2, a 2 × 2 between-subjects experimental design, provides further support for our moderated mediation model. Results reveal that participants experience negative emotions when they receive information that they are more ethical than a comparison participant. Negative emotions are amplified if the participant is told they were a lower performer than the comparison participant. Those participants indicate their desire to mistreat and ignore the comparison participant if given the opportunity. Thus, we find support for our hypotheses using a multi-method design. (shrink)

Spinoza was one of the most influential figures of the Enlightenment, but his often obscure metaphysics makes it difficult to understand the ultimate message of his philosophy. Although he regarded freedom as the fundamental goal of his ethics and politics, his theory of freedom has not received sustained, comprehensive treatment. Spinoza holds that we attain freedom by governing ourselves according to practical principles, which express many of our deepest moral commitments. Matthew J. Kisner focuses on this theory and presents (...) an alternative picture of the ethical project driving Spinoza's philosophical system. His study of the neglected practical philosophy provides an accessible and concrete picture of what it means to live as Spinoza's ethics envisioned. (shrink)

In this article, I consider the neglected question of justice between states in the distribution of responsibility for refugees. I argue that a just distribution of refugees across states is an important normative goal and, accordingly, I attempt to rethink the normative foundations of the global refugee regime. I show that because dismantling the restrictive measures currently used by states in the global South to prevent the arrival of refugees will not suffice to ensure a just distribution of refugees between (...) states, a more detailed account of how responsibilities should be shared between states is required. To this end, I make three claims. First, I argue that the definition of ‘refugee’ must be broadened beyond those subjected to persecution to include harms of action or omission by states that seriously jeopardise personal security or subsistence needs. Second, I argue that allocating a fair share of refugees to states should be based on state’s integrative capacities. Finally, I argue that distributive justice between states must be balanced against the legitimate interests of refugees in their destination country and the duty of states to ensure they are settled in places where they are likely to flourish.

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

A far-reaching and influential view in evolutionary biology claims that species are cohesive units held together by gene flow. Biologists have recognized empirical problems facing this view; after sharpening the expression of the view, we present novel conceptual problems for it. At the heart of these problems is a distinction between two importantly different concepts of cohesion, what we call integrative and response cohesion. Acknowledging the distinction problematizes both the explanandum of species cohesion and the explanans of gene flow that (...) are central to the view we discuss. We conclude by tracing four broader implications for the study and conceptualization of species. (shrink)

Based on the French notion of terroir or ‘the taste of place,’ a certified geographical indication (GI) identifies an agro-food product as originating in a particular territory and suggests that its quality, reputation, or other characteristics are essentially or exclusively attributable to its geographical origin. Previous scholarship exploring the social construction of terroir has focused on how disparities in political, economic, and cultural power shape GI regulations, certification procedures, and territorial boundaries. While these works have considered knowledge as a resource (...) deployed through relations of authority, studies of GI implementation have not adequately considered an important aspect of power in contemporary politics: the epistemic authority to assert the legitimacy of knowledge and its relevance to policymaking. In contrast, in this article, I take the accomplishment of epistemic authority – to determine the ‘essential’ and ‘exclusive’ physical and/or cultural attributes of place that shape product character – as key to the social construction of terroir and the institutionalization of GI regulations. This process is explored through a case study of Ecuador’s 2013-2019 implementation of a GI for Galápagos Islands coffee. I draw on analysis of relevant policy and regulatory documents and semi-structured interviews with 21 key stakeholders to argue that analytical attention to the legitimacy and relevance of terroir knowledge explains how coffee producers were able to deploy authoritative knowledge to disrupt and reinforce relations of authority and challenge the terms and mechanisms of GI qualification.

In the face of the desperate plight of refugees, virtually all moral and political philosophers, regardless of their general position on immigration controls, argue that states have a duty to grant asylum: people must not be turned back to countries where they would face persecution or severe human rights violations. Yet this consensus obscures a number of thorny ethical issues raised by the plight of the displaced. In this piece, I want to draw from recent writing in political and ethical (...) theory to bring some of these issues into view. I start by considering what a refugee is, before turning to the question how the obligations of political communities to the displaced are grounded. I then move to consider what societies owe to refugees and the question of international justice in the allocation of asylum. I conclude with a discussion of the moral responsibilities of refugees themselves. (shrink)

Pluralisms of various sorts are popular in philosophy of science, including those that imply some scientific concept x should be eliminated from science in favour of a plurality of concepts x1, x2, … xn.

The processes mediating dynamic and flexible responding to rapidly changing task-environments are not well understood. In the present research we employ a Stroop procedure to clarify the contribution of context-sensitive control processes to online performance. In prior work Stroop interference varied as a function of probe location context, with larger Stroop interference occurring for contexts associated with a high proportion of congruent items [Crump, M. J., Gong, Z., & Milliken, B. . The context-specific proportion congruent stroop effect: location as a (...) contextual cue. Psychonomic Bulletin & Review, 13, 316–321.] Here, we demonstrate that this effect does not depend on awareness of the context manipulation, but that it can depend on attention to the predictive context dimension, and on the relative salience of the target and predictive context dimensions. We discuss the implications of our results for current theories of cognitive control. (shrink)

We argue for a new conventionalism about many kinds of evolutionary groups, including clades, cohesive units, and populations. This rejects a consensus, which says that given any one of the many legitimate grouping concepts, only objective biological facts determine whether a collection is such a group. Surprisingly, being any one kind of evolutionary group typically depends on which of many incompatible values are taken by suppressed variables. This is a novel pluralism underlying most any one group concept, rather than a (...) familiar pluralism claiming many concepts are legitimate. Consequently, we must help biological facts determine grouphood, even when given a single grouping concept. (shrink)
