A complete theory of harming must have both a substantive component and a formal component. The substantive component, which Victor Tadros (2014) calls the “currency” of harm, tells us what I interfere with when I harm you. The formal component, which Tadros calls the “measure” of harm, tells us how the harm to you is related to my action. In this chapter I survey the literature on both the currency and the measure of harm. I argue that the currency of (...) harm is well-being and that the measure of harming is best captured by a causal account on which harming is causing a harm. A harm for you is the presence of something intrinsically bad for you or the absence of something intrinsically good for you. Thus, although a counterfactual account of the measure of harm need not distinguish between an harm and a harmful event, the causal account reserves the term ‘harm’, not for a harmful event, but only for its effect. Finally, I show how a complete theory of harming can help us to answer questions about whether we can harm people with speech, whether we can harm the dead, and how it is possible to harm future generations.

The Protestant ethic — a moral code stressing hard work, rigorous self-discipline, and the organization of one's life in the service of God — was made famous by sociologist and political economist Max Weber. In this brilliant study (his best-known and most controversial), he opposes the Marxist concept of dialectical materialism and its view that change takes place through "the struggle of opposites." Instead, he relates the rise of a capitalist economy to the Puritan determination to work out anxiety over (...) salvation or damnation by performing good deeds — an effort that ultimately discouraged belief in predestination and encouraged capitalism. Weber's classic study has long been required reading in college and advanced high school social studies classrooms. (shrink)

Cet article répond aux critiques de Latour selon lesquelles Canguilhem, vénérant la science, était incapable d’en écrire l’histoire. Je soutiens, au contraire, que Canguilhem a poursuivi une philosophie critique qui cherche les limites de diverses pratiques, y compris celles des rationalités et idéologies scientifiques. Bien qu’il défende l’efficacité d’une pratique médicale scientifiquement informée, il en identifie également les limites en interprétant les mouvements anti-médicaux comme des réponses aux échecs d’une médecine considérée comme infaillible parce que scientifique. Pour Canguilhem, la pratique (...) médicale doit être comprise en elle-même plutôt que considérée comme une application de connaissances scientifiques. En conséquence, il s’intéresse aux sciences dans leur rapport à la pratique médicale. Pour répondre en détail à l’accusation de Latour, cet article étudie la préoccupation fondamentale de la philosophie critique de Canguilhem. S’il s’agissait d’établir quelque vérité, valeur par excellence de la science selon Canguilhem, alors il semble que la critique serait valable. Mais en considérant attentivement l’histoire de ses projets et de ses réalisations telle que racontée dans son discours de réception de la médaille d’or du CNRS en 1987, cet article soutient au contraire que sa philosophie critique ne vénère pas la science, mais trouve son orientation ailleurs. En accordant une attention particulière à son intérêt constant pour l’erreur, et à sa distinction entre l’erreur intellectuelle et les essais et erreurs de la vie, je soutiens que sa philosophie critique s’intéresse en fin de compte à l’action et à la promotion du courage requis par la vie humaine.

One fall evening in 1880, Russian painter Ilya Repin welcomed an unexpected visitor to his home: Lev Tolstoy. The renowned realists talked for hours, and Tolstoy turned his critical eye to the sketches in Repin's studio. Tolstoy's criticisms would later prompt Repin to reflect on the question of creative expression and conclude that the path to artistic truth is relative, dependent on the mode and medium of representation. In this original study, Molly Brunson traces many such paths that converged (...) to form the tradition of nineteenth-century Russian realism, a tradition that spanned almost half a century--from the youthful projects of the Natural School and the critical realism of the age of reform to the mature masterpieces of Tolstoy, Fyodor Dostoevsky, and the paintings of the Wanderers, Repin chief among them. By examining the classics of the tradition, Brunson explores the emergence of multiple realisms from the gaps, disruptions, and doubts that accompany the self-conscious project of representing reality. These manifestations of realism are united not by how they look or what they describe, but by their shared awareness of the fraught yet critical task of representation. By tracing the engagement of literature and painting with aesthetic debates on the sister arts, Brunson argues for a conceptualization of realism that transcends artistic media. Russian Realisms integrates the lesser-known tradition of Russian painting with the familiar masterpieces of Russia's great novelists, highlighting both the common ground in their struggles for artistic realism and their cultural autonomy and legitimacy. This erudite study will appeal to scholars interested in Russian literature and art, comparative literature, art history, and nineteenth-century realist movements. (shrink)

A surprising intellectual ally to Christians, Plato confronted relativism, materialism, and hedonism. In this critical overview, Talcott shows where he brought useful insight and where he fell short in notable ways.

This book brings together, in systematic and generalized form, the main outlines of a conceptual scheme for the analysis of the structure and processes of social systems. It carries out Pareto's intention by using the "structural-functional" level of analysis.

This article advances some considerations that undermine the overall justification for what I call “beneficent interventions,” or interventions aimed at reducing the suffering of wild animals. I first appeal to Susan Wolf’s (2010) account of meaning in life to argue that wild animals can and do have meaning in their lives. I then argue that the meaning in animal lives can offset their suffering, making their lives more worth living. This source of positive value in the lives of wild animals (...) undermines some of the justification for those beneficent interventions that aim to reduce wild animal suffering by reducing the numbers of wild animals who either suffer or inflict suffering upon others.

The lack of gender parity in philosophy has garnered serious attention recently. Previous empirical work that aims to quantify what has come to be called “the gender gap” in philosophy focuses mainly on the absence of women in philosophy faculty and graduate programs. Our study looks at gender representation in philosophy among undergraduate students, undergraduate majors, graduate students, and faculty. Our findings are consistent with what other studies have found about women faculty in philosophy, but we were able to add (...) two pieces of new information. First, the biggest drop in the proportion of women in philosophy occurs between students enrolled in introductory philosophy classes and philosophy majors. Second, this drop is mitigated by the presence of more women philosophy faculty. (shrink)

Can advances in neuroscience be harnessed to enhance human moral capacities? And if so, should they? De Grazia explores these questions in ‘Moral Enhancement, Freedom, and What We Value in Moral Behaviour’.1 Here, I offer a neuroscientist's perspective on the state of the art of moral bioenhancement, and highlight some of the practical challenges facing the development of moral bioenhancement technologies.The science of moral bioenhancement is in its infancy. Laboratory studies of human morality usually employ highly simplified models aimed at (...) measuring just one facet of a cognitive process that is relevant for morality. These studies have certainly deepened our understanding of the nature of moral behaviour, but it is important to avoid overstating the conclusions of any single study. De Grazia cites several purported examples of ‘non-traditional means of moral enhancement’, including one of my own studies. According to De Grazia, we showed that ‘selective serotonin reuptake inhibitors as a means to being less inclined to assault people’. In fact, our findings are a bit more subtle and nuanced than implied in the target article, as is often the case in neuroscientific studies of complex human behaviour. In our study, we tested the effects of the selective serotonin reuptake …. (shrink)

This chapter offers a philosophical reconstruction of philosophical views on epistemic practices and the social practical basis of authority in order to make sense of Richard Rorty's anxieties about religion's role in democratic life. It shows that the philosophical views can also be used to construct an approach to religious pluralism that is far more open‐ended and dialogical than the approach that Rorty chose to pursue. The chapter reviews Rorty's call for the privatization of religion in light of his broader (...) view of epistemic practices. Rorty's two main anxieties about religion come from his view of the social practical basis of authority. His tendency to generalize about the dangers of religion in public life was shaped by the culture wars of the 1990s, the political and cultural struggle between liberal secularists and the religious right over issues such as abortion and homosexuality.

Incarcerated offenders are categorically high-risk patients who are disproportionately more likely to suffer from chronic illnesses than members of the general population. The conditions of confinement (e.g., overcrowding, poor nutrition, risky sexual practices) furthermore make them increasingly susceptible to acquiring an infectious disease. Past research has linked preventive care, including the early detection and treatment of such diseases, with better long-term health outcomes; however, such care is not universally provided to this population. The benefits and current availability of preventive care (...) for incarcerated offenders is discussed and several questions are raised for future discussion within a global context. In particular, these questions include whether or not incarcerated offenders should receive preventive care, the underlying reason for such provision, who should advocate for and for be responsible for their access to preventive care, and the mechanisms through which access could be attained.

In this 2020 AFHVS Presidential Address, Molly Anderson suggests that we must push beyond the boundaries imposed by our training, institutional reward systems, political system and comfort zones in order to solve global challenges. She lists five challenges facing those who are trying to build more sustainable food systems: overcoming the technocratic and productivist approach of industrial agriculture, avoiding future pandemics, restoring degraded and depleted systems and resources, remaining united as a movement while creating collaborations with other movements, and (...) redistributing power across food system actors so that everyone can realize their human rights, including the right to food. She describes three ways that she has found to be effective in pushing beyond boundaries: international collaborations, interactions with global social movements, and anti-racist work. She links these “moments” of opportunity back to the five challenges, and concludes with advice to young scholars. (shrink)

In this collection, the editors again bring together papers that either exemplify the crossing of disciplinary boundaries, or that allow us to do so in and through the conversations they create. The chapters were chosen based on their relevance to similar themes as were discussed in the first volume. By reviewing historical developments in the literature around gender and organization, and by drawing on recent scholarship that disrupts the traditional masculine imaginaries that plague leadership constructs, this book challenges us to (...) radically revise our gendered thinking about leading in organizations. The authors included in this volume offer alternative, interdisciplinary perspectives on the gender constructs that inform the organizing that takes place in business and society. The book delves deeply into how ‘relationality’, as concept and practice, can help us frame a more inclusive approach to gender within contemporary organizations. (shrink)

Though we often “fear the worst”, worrying that unexpectedly bad things will happen, there are times when we “hope for the best”, imagining that unexpectedly good things will happen, too. The paper explores how the valence of the current situation influences people's imagining of unexpected future events when participants were instructed to think of “something unexpected”. In Experiment 1, participants (N = 127) were asked to report unexpected events to everyday scenarios under different instructional conditions (e.g., asked for “good” or (...) “bad” unexpected events), and manifested a strong negativity bias in response to non-valenced instructions (i.e., being asked to “think of the unexpected” with no valence given). They mainly reported quite “predictable” unexpected outcomes that were negative; however, a post-test (N = 31) showed that the scenarios used were predominantly positive. In Experiment 2 (N = 257), when participants were instructed to think of “something unexpected and bizarre”, under the same instructional manipulations as Experiment 1, this negativity bias was replicated. In Experiment 3, using a design in which positive/negative materials were matched (verified by a pre-test, N = 60), it was found that when participants (N = 102) were given negative scenarios, they reported more positive events than they do when they are given positive scenarios. Though responding still retained an overwhelming negative bias, this result provided some evidence for a weaker valence-countering strategy; that is, where a negative scenario can lead to positive unexpected events being mentioned, and a positive scenario leads to negative unexpected events being reported. The implications of these results for people's projections of unexpected futures in their everyday lives is discussed. (shrink)

Food security, health, decent livelihoods, gender equity, safe working conditions, cultural identity and participation in cultural life are basic human rights that can be achieved at least in part through the food system. But current trends in the US prevent full realization of these economic, social, and cultural rights (ESCR) for residents, farmers, and wageworkers in the food system. Supply chains that strive to meet the goals of social justice, economic equity, and environmental quality better than the dominant globalized food (...) value networks are gaining popularity in the US. However, achieving important human rights has become conflated with other goals of food system reform over the past decade, such as being “community-based,” local, and sustainable. This conflation confuses means, ends, and complementary goals; and it may lead activists trying to help communities to regain control of their food system choices into less productive strategies. This paper introduces a new concept, rights-based food systems (RBFS), and explores its connection with localization and sustainability. The core criteria of RBFS are democratic participation in food system choices affecting more than one sector; fair, transparent access by producers to all necessary resources for food production and marketing; multiple independent buyers; absence of human exploitation; absence of resource exploitation; and no impingement on the ability of people in other locales to meet this set of criteria. Localization and a community base can help achieve RBFS by facilitating food democracy and reducing environmental exploitation, primarily by lowering environmental costs due to long-distance transportation. Sustainability per se is an empty goal for food system reform, unless what will be sustained and for whom are specified. The RBFS concept helps to clarify what is worth sustaining and who is most susceptible to neglect in attempts to reform food systems. Localization can be a means toward sustainability if local food systems are also RBFS. (shrink)

The Neuroethics Affinity Group of the American Society for Bioethics and Humanities met for the third time in October 2007 to review progress in the field of neuroethics and consider high-impact priorities for the future. Closely aligned with ASBH's own goals of recruiting junior scholars to bioethics and mentoring them to successful careers, the Neuroethics Affinity Group placed a call for new ideas to be presented at the Group meeting, specifically by junior attendees. One group responded with the idea to (...) probe a new direction for neuroethics focused on the neuroscience of gender differences. In the spirit of full disclosure, two of the authors are a student and fellow of the program I formerly directed at Stanford University. The third is junior faculty there. The intellectual ownership of the ideas in the report below, however, are entirely theirs. Like lit torches in a juggling act, there are many directions this project can go. The report is a snapshot of these authors' first iteration of the concept of women's neuroethics. Many thanks are extended to participants of the ASBH Neuroethics Affinity Group meeting whose enthusiasm and feedback was immensely helpful in shaping the concept and moving it ahead. - Judy Illes, Editor AJOB-Neuroscience.

Both individuals with diagnosed with Autism Spectrum Disorder and individuals high in psychopathic traits show reduced susceptibility to contagious yawning; that is, yawning after seeing or hearing another person yawn. Yet it is unclear whether the same underlying processes are responsible for the relationship between reduced contagion and these very different types of clinical traits. College Students watched videos of individuals yawning or scratching while their eye movements were tracked. They completed the Interpersonal Reactivity Index, the Autism-Spectrum Quotient, the Psychopathy (...) Personality Inventory-Revised, and the Adolescent and Adult Sensory Processing Disorder Checklist. Both psychopathic traits and autistic traits showed an inverse relationship to contagious yawning, consistent with previous research. However, the relationship between autistic traits and contagious yawning was moderated by eye gaze. Furthermore, participants high in autistic traits showed typical levels of contagious itching whereas adults high in psychopathic traits showed diminished itch contagion. Finally, only psychopathic traits were associated with lower overall levels of empathy. The findings imply that the underlying processes contributing to the disruptions in contagious yawning amongst individuals high in autistic vs. psychopathic traits are distinct. In contrast to adults high in psychopathic traits, diminished contagion may appear amongst people with high levels of autistic traits secondary to diminished attention to the faces of others, and in the absence of a background deficit in emotional empathy.

Discusses the base from which modern societies developed.

Many of us agree that we ought not to wrong future people, but there remains disagreement about which of our actions can wrong them. Can we wrong individuals whose lives are worth living by taking actions that result in their very existence? The problem of justifying an answer to this question has come to be known as the non-identity problem.[1] While the literature contains an array of strategies for solving the problem,[2] in this paper I will take what I call (...) the harm-based approach, and I will defend an account of harming—which I call the existence account of harming—that can vindicate this approach. -/- Roughly put, the harm-based approach holds that, by acting in ways that result in the existence of individuals whose lives are worth living, we can harm and thereby wrong those individuals. An initially plausible way to try to justify this approach is to endorse the non-comparative account of harming, which holds that an event harms an individual just in case it causes her to be in a bad state, such that the state’s badness does not derive from a comparison between that state and some alternative state that the individual would or could have been in. However, many philosophers argue that the non-comparative account of harming is inadequate,[3] and one might be tempted to infer from this that any harm-based approach to the non-identity problem will fail. My proposal, which I call the existence account of harming, will show that this inference is faulty: we can vindicate the harm-based approach without relying on the non-comparative account of harming.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.3 (2000) v-vii [Access article in PDF] On Feminizing the Philosophy of Rhetoric Molly Meijer Wertheimer When asked to define his editorial policies in choosing articles to publish in Philosophy and Rhetoric, Henry W. Johnstone Jr. disavowed following any strict editorial guidelines; instead, he gave two examples to show how selection worked as a process. In one case, he agreed to publish an "off the (...) wall article" by a distinguished classicist; in another, he accepted an unusually long article--a "behemoth"--by an eminent rhetorician. These examples demonstrate what was to me one of Henry's most unusual and endearing traits as an editor and scholar: he was willing always to go wherever the argument led. It was probably in this spirit that he agreed to publish a special issue on "Feminizing the Philosophy of Rhetoric." I want to thank him posthumously for that decision. As "guest editor" of the issue, I feel privileged to present four well-written essays and two reviews that lead the readers of Philosophy and Rhetoric to consider some philosophical issues that emerge when we overlap concepts of "gender," "culture," and "rhetoric."The essays in this issue explore tactics women have used to get their messages across to others who would not--even could not--entertain speech seriously if presented by a woman. In the first essay, "Unveiling Esther as a Pragmatic Radical Rhetoric," Susan Zaeske reads the Book of Esther as a rhetorical manual of exile and empowerment. She traces features of the narrative that were useful as a model of rhetorical behavior early on, as well as appropriations that were made throughout the Middle Ages, Antebellum South, and even in our own day. Her essay emphasizes the riskiness to the speaker that is often entailed by the act of speaking, especially when the listener is "all-powerful" (199); when "his decisions are based not on careful deliberation, but on who influences him the most, usually by prodding his sense of power and manliness" (200). In the narrative, the speaker, Queen Esther, is depicted as utterly thoughtful, careful, well planned and well timed. She seems very much in control of an "indirect" rhetoric. Says Zaeske, "[T]he book teaches that direct, resistant rhetoric is ineffective, even dangerous, while clever, indirect, noncon- frontational methods will succeed in gaining the desired end--power" (202). [End Page v] This is a "conciliatory strategy wise women are forced to use in the patriarchal world" (qtd. on p. 202). And this kind of strategy is contrasted to the defiant rhetoric of Vashti, the former queen, Esther's predecessor, who was banished for saying no to one of the king's commands. Silence and supplication, according to Zaeske, when adopted self-consciously as strategies, are effective with hostile, neanderthal-type auditors. They are "radical," at least in the sense that they are "extreme."Nan Johnson, in her essay "Reigning in the Court of Silence: Women and Rhetorical Space in Postbellum America," furthers discussion of women's rhetorical options. In Zaeske's essay, women assume positions of supplicants or petitioners, or they stand defiant in the face of an oppressive listener (the king). The former are idolized; the latter are demonized. Centuries later, in the fifty years following the Civil War, similar representations of women appeared in conduct literature. Johnson describes a media blitz of ideas and images in etiquette and other self-help manuals that sought to define rhetorical behaviors and actions appropriate for men and women. Some of the writings idolized the "quiet woman" of the home, who reigned silently as queen stitching together via indirection a rhetoric of nurturance that moved beyond the home only through the actions of husbands and sons. This kind of rhetoric was viewed as a natural consequence of femininity. Other writings demonized the woman who spoke from the public platform as a teacher, preacher, and advocate, and who needed a rhetorical education to do so effectively. Many writings highlighted the negative consequences of rhetorical experience to women (who risked their femininity and the love of their families) and to their families (who risked the true source of...

In _The Excessive Subject: A New Theory of Social Change_, Molly Anne Rothenberg uncovers an innovative theory of social change implicit in the writings of radical social theorists, such as Pierre Bourdieu, Michel de Certeau, Judith Butler, Ernesto Laclau, and Slavoj?i?ek. Through case studies of these writers' work, Rothenberg illuminates how this new theory calls into question currently accepted views of social practices, subject formation, democratic interaction, hegemony, political solidarity, revolutionary acts, and the ethics of alterity. Finding a common (...) dissatisfaction with the dominant paradigms of social structures in the authors she discusses, Rothenberg goes on to show that each of these thinkers makes use of Lacan's investigations of the causality of subjectivity in an effort to find an alternative paradigm. Labeling this paradigm 'extimate causality', Rothenberg demonstrates how it produces a nondeterminacy, so that every subject bears some excess; paradoxically, this excess is what structures the social field itself. Whilst other theories of social change, subject formation, and political alliance invariably conceive of the elimination of this excess as necessary to their projects, the theory of extimate causality makes clear that it is ineradicable. To imagine otherwise is to be held hostage to a politics of fantasy. As she examines the importance as well as the limitations of theories that put extimate causality to work, Rothenberg reveals how the excess of the subject promises a new theory of social change. By bringing these prominent thinkers together for the first time in one volume, this landmark text will be sure to ignite debate among scholars in the field, as well as being an indispensable tool for students.

In lieu of an abstract, here is a brief excerpt of the content:A Brit Milah for Eliezer Herschel ben Yonatan AryehMolly SinderbrandFor observant Jews, the choice to circumcise one's son is not a choice. Technically, it is a contractual obligation; the belief is that male circumcision is part of a holy covenant with God. The word for ritual circumcision, brit milah or bris, literally means "covenant [of circumcision]." Circumcision is a physical symbol of a relationship with the divine. It is (...) the commandment that encompasses all other commandments. It is, thankfully, only required of men (women, they say, are naturally closer to divinity). Circumcision is when a baby boy enters the Jewish community, eight days after birth, and when he gets his name. He becomes somebody. To choose otherwise— and some may choose otherwise—is to choose not to be part of the contract, and by extension, not be part of the Jewish community. And a community is one of the most valuable things a person can have.I was not always an observant Jew, though I was raised in a Jewish household. I essentially fell into observance over a period of 10 years, starting with studying ancient Hebrew with a language-loving rabbi in high school and eventually leading to weekly attendance at an orthodox shul, which I joined shortly after first tasting the vegan cholent at kiddush. It was much easier to make friends in [End Page 91] the Jewish community than in my competitive and mildly misogynist graduate program, and frankly, I liked them better. I received kindness and support when I needed it, and gave it back equally, especially around having children. Having children is difficult under any circumstance, but it is especially difficult in social settings where it is seen as abnormal, strange, or even selfish. The Jewish community normalized having children and created a respite from the judgment of the secular world. When I was pregnant at work, I got comments like "It looks like you're having twins!" and "Are you sure you don't have pre-eclampsia? You look awfully large"; at shul, I got pep talks, encouragement, and the traditional "b'sha'a tova"—"may it happen at a good time."Eventually, after having two kids in a two-bedroom rowhome, my husband and I moved to a mostly-Jewish suburb just outside the city. It is the kind of place where everyone says "Gut Shabbes" (a good Sabbath) to each other on Saturdays, but not one in which all the men wear black hats and study Torah all day (though some do). That is, folks live Jewish lives, but interact with the outside world as well. After a few months, it felt like home.This was the context in which I decided—or rather, did not have to decide—to circumcise my son. It was the natural result of the decision to be part of a community that places value (and even membership) on the ritual of circumcision. I made that decision years earlier and have been continuously reaffirming it since. Every day I wake up is a day I decide to be an observant Jew, and I decide to do so in order to be a member of an observant community. The decision to circumcise was yet another decision to be part of that community, which has given me so much joy, support, and meaning. Why would I deny my son—and myself—that community?In addition, not needing to make any decisions was itself a kind of relief. I have heard of mothers—including my own—off in a room crying, needing comfort, unable to be there for the circumcision. That did not happen for me. Despite a history of rather severe perinatal depression and anxiety, including suicidal ideation less than a week before the event, I was completely fine. Maybe my comfort came from the fact that I already had two children; this was not my first newborn, though it was my first bris. Maybe, after almost two years of COVID, circumcision did not seem like such a big deal. Maybe I was just glad someone else would hold the baby for a while. But I think at least part of it was the happiness that... (shrink)

We report on an unpublished and previously unknown manuscript of John von Neumann and contextualize it within the development of the theory of shock waves and detonations during the nineteenth and twentieth centuries. Von Neumann studies bombs comprising a primary explosive charge along with explosive booster material. His goal is to calculate the minimal amount of booster needed to create a sustainable detonation, presumably because booster material is often more expensive and more volatile. In service of this goal, he formulates (...) and analyzes a partial differential equation-based model describing a moving shock wave at the interface of detonated and undetonated material. We provide a complete transcription of von Neumann’s work and give our own accompanying explanations and analyses, including the correction of two small errors in his calculations. Today, detonations are typically modeled using a combination of experimental results and numerical simulations particular to the shape and materials of the explosive, as the complex three dimensional dynamics of detonations are analytically intractable. Although von Neumann’s manuscript will not revolutionize our modern understanding of detonations, the document is a valuable historical record of the state of hydrodynamics research during and after World War II.
