Machine learning algorithms pervade contemporary society. They are integral to social institutions, inform processes of governance, and animate the mundane technologies of daily life. Consistently, the outcomes of machine learning reflect, reproduce, and amplify structural inequalities. The field of fair machine learning has emerged in response, developing mathematical techniques that increase fairness based on anti-classification, classification parity, and calibration standards. In practice, these computational correctives invariably fall short, operating from an algorithmic idealism that does not, and cannot, address systemic, Intersectional (...) stratifications. Taking present fair machine learning methods as our point of departure, we suggest instead the notion and practice of algorithmic reparation. Rooted in theories of Intersectionality, reparative algorithms name, unmask, and undo allocative and representational harms as they materialize in sociotechnical form. We propose algorithmic reparation as a foundation for building, evaluating, adjusting, and when necessary, omitting and eradicating machine learning systems. (shrink)

Like Jeffrey Friedman's proposed postlibertarianism, mainstream libertarianism has always emphasized the consequences of alternative institutions for human well‐being. Mainstream libertarianism does, however, share some similarities with the radical libertarianism criticized by Friedman, as can be seen by considering possible answers to the questions Alec Nove recently posed for postlibertarians.

This paper posits that organizational variables are the factors that lead to the moral decline of companies like Enron and Worldcom. The individuals involved created environments within the organizations that precipitated a spiral of unethical decision-making. It is proposed that at the executive level, it is the organizational factors associated with power and decision-making that have the critical influence on moral and ethical behavior. The study has used variables that were deemed to be surrogate measures of the ethical violations (OSHA (...) and EPA violations), the risky shift phenomenon (executive team size), banality of wrong-doing (reputation score for firms) and escalating commitment (tenure with the firm/change in revenue for declining firms). The research found that there were small correlations between ethical violations and the three organizational variables. (shrink)

Can corporations remain socially responsible in today's fiercely competitive global economy? For several decades after World War II, companies like IBM, which exemplified what journalist Robert J. Samuelson called the 'good corporation,' poured forth material comforts and technological ideas while guaranteeing full employment and adequate retirement. In the 1980s all of that changed, as corporations moved to 'downsize' and become lean, mean global competitors. In this collection, thirteen prominent scholars in business ethics, finance, management, and religion and six corporate leaders (...) respond to a new essay by Samuelson that sounds the death knell of the 'good corporation.' They propose new approaches to corporate integrity and social responsibility in the global economy. The book will be useful in corporate workshops and will make an excellent business ethics text in philosophy departments and business schools. (shrink)

Pleiotropy, in which one mutation causes multiple phenotypes, has traditionally been seen as a deviation from the conventional observation in which one gene affects one phenotype. Epistasis, or gene–gene interaction, has also been treated as an exception to the Mendelian one gene–one phenotype paradigm. This simplified perspective belies the pervasive complexity of biology and hinders progress toward a deeper understanding of biological systems. We assert that epistasis and pleiotropy are not isolated occurrences, but ubiquitous and inherent properties of biomolecular networks. (...) These phenomena should not be treated as exceptions, but rather as fundamental components of genetic analyses. A systems level understanding of epistasis and pleiotropy is, therefore, critical to furthering our understanding of human genetics and its contribution to common human disease. Finally, graph theory offers an intuitive and powerful set of tools with which to study the network bases of these important genetic phenomena. (shrink)

By the time of his death in 2003, Bernard Williams was one of the greatest philosophers of his generation. Ethics and the Limits of Philosophy is not only widely acknowledged to be his most important book, but also hailed a contemporary classic of moral philosophy. Presenting a sustained critique of moral theory from Kant onwards, Williams reorients ethical theory towards ‘truth, truthfulness and the meaning of an individual life’. He explores and reflects upon the most difficult problems in (...) contemporary philosophy and identifies new ideas about central issues such as relativism, objectivity and the possibility of ethical knowledge. This edition also includes a new commentary on the text by A.W.Moore and a foreword by Jonathan Lear. (shrink)

In this ambitious study, Alexander W. Hall examines the two preeminent figures of the golden age of natural theology: Thomas Aquinas and John Duns Scotus. Hall is not so much concerned with retracing particular proofs of the existence of God and derivations of the divine attributes—well-worn paths in discussions of medieval natural theology—as with investigating the larger philosophical issues that are raised by the project of natural theology, such as the nature of scientia and demonstrative arguments, and accounts of signification (...) and the meaningfulness of theological discourse.Hall's opening chapter offers an overview of natural theology in the High Middle Ages, summarizing the conclusions he will defend at greater length over the course of the book. In chapter 2 Hall relies primarily on Aquinas's commentary on the Posterior Analytics to get clear on his account of scientia, or scientific knowledge. "For Aquinas," Hall writes,"paradigmatic scientia is the result of syllogistic reasoning . . . Syllogisms productive of scientia use either real or nominal definitions as their middle, and thus the conclusion tells us what belongs to the subject through itself or per se". (shrink)

This paper considers W.E.B. Du Bois’s short story, “Jesus Christ in Texas,” in the perspective of his analysis of the concept of beauty in Darkwater (1920); his exposition of the idea that “all art is propaganda” in “Criteria of Negro Art” (1926); and his moral psychology of white supremacy. On my account, Du Bois holds that beautiful art can help to undermine white supremacy by using representations of moral goodness to expand the white supremacist’s ethical horizons. To defend this thesis, (...) he relies on an image of “the cross and the lynching tree” to revise imagery that he draws from Albrecht Dürer’s 1504 painting, “The Adoration of Kings.”. (shrink)

What can--and what can't--philosophy do? What are its ethical risks--and its possible rewards? How does it differ from science? In Philosophy as a Humanistic Discipline, Bernard Williams addresses these questions and presents a striking vision of philosophy as fundamentally different from science in its aims and methods even though there is still in philosophy "something that counts as getting it right." Written with his distinctive combination of rigor, imagination, depth, and humanism, the book amply demonstrates why Williams was (...) one of the greatest philosophers of the twentieth century. Spanning his career from his first publication to one of his last lectures, the book's previously unpublished or uncollected essays address metaphysics, epistemology, and ethics, as well as the scope and limits of philosophy itself. The essays are unified by Williams's constant concern that philosophy maintain contact with the human problems that animate it in the first place. As the book's editor, A. W. Moore, writes in his introduction, the title essay is "a kind of manifesto for Williams's conception of his own life's work." It is where he most directly asks "what philosophy can and cannot contribute to the project of making sense of things"--answering that what philosophy can best help make sense of is "being human." Philosophy as a Humanistic Discipline is one of three posthumous books by Williams to be published by Princeton University Press. In the Beginning Was the Deed: Realism and Moralism in Political Argument was published in the fall of 2005. The Sense of the Past: Essays in the History of Philosophy is being published shortly after the present volume. (shrink)

Abstractabstract:In his Pragmatism lectures, William James argued that philosophers' temperaments partially determine the theories that they find satisfying, and that their influence explains persistent disagreement within the history of philosophy. Crucially, James was not only making a descriptive claim, but also a normative one: temperaments, he thought, could play a legitimate epistemic role in our philosophical inquiries. This paper aims to evaluate and defend this normative claim.There are three problems for James's view: (1) that allowing temperaments to play a role (...) within inquiry replaces philosophical disagreement with psychological difference; (2) that including temperaments would allow arbitrary elements to influence the outcome of inquiry; and (3) that such a view assumes an implausible metaphysical picture. Through clarifying the nature of temperaments, and what counts as a satisfactory philosophical theory on a pragmatist account, this paper presents an interpretation of James's metaphilosophical claims that can provide satisfactory responses to these problems.

Current theories suggest that the brain is the sole source of mental illness. However, affective disorders, and major depressive disorder (MDD) in particular, may be better conceptualized as brain-body disorders that involve peripheral systems as well. This perspective emphasizes the embodied, multifaceted physiology of well-being, and suggests that afferent signals from the body may contribute to cognitive and emotional states. In this review, we focus on evidence from preclinical and clinical studies suggesting that afferent thermosensory signals contribute to well-being and (...) depression. Although thermoregulatory systems have traditionally been conceptualized as serving primarily homeostatic functions, increasing evidence suggests neural pathways responsible for regulating body temperature may be linked more closely with emotional states than previously recognized, an affective warmth hypothesis. Human studies indicate that increasing physical warmth activates brain circuits associated with cognitive and affective functions, promotes interpersonal warmth and prosocial behavior, and has antidepressant effects. Consistent with these effects, preclinical studies in rodents demonstrate that physical warmth activates brain serotonergic neurons implicated in antidepressant-like effects. Together, these studies suggest that (1) thermosensory pathways interact with brain systems that control affective function, (2) these pathways are dysregulated in affective disorders, and (3) activating warm thermosensory pathways promotes a sense of well-being and has therapeutic potential in the treatment of affective disorders.

Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

In this essay I consider the argument that Bernard Williams advances in ‘The Makropolus Case’ for the meaninglessness of immortality. I also consider various counter-arguments. I suggest that the more clearly these counter-arguments are targeted at the spirit of Williams's argument, rather than at its letter, the less clearly they pose a threat to it. I then turn to Nietzsche, whose views about the eternal recurrence might appear to make him an opponent of Williams. I argue that, (...) properly interpreted, these views in fact make him an ally.

In the opening to his late essay, Der Gedanke, Frege asserts without qualification that the word "true" points the way for logic. But in a short piece from his Nachlass entitled "My Basic Logical Insights", Frege writes that the word true makes an unsuccessful attempt to point to the essence of logic, asserting instead that "what really pertains to logic lies not in the word "true" but in the assertoric force with which the sentence is uttered". Properly understanding what Frege (...) takes to be at issue here is crucial for understanding his conception of logic and, in particular, what he takes to be its normative status vis-à-vis judgement, assertion, and inference. In this paper, I focus my attention on clarifying the latter claim and Frege's motivations for making it, exposing what I take to be a fundamental tension in Frege's conception of logic. Finally, I discuss whether Frege's deployment of the horizontal in his mature Begriffsschrift helps to resolve this tension. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Justice and the General Will:Affirming Rousseau's Ancient OrientationDavid Lay WilliamsThere is much confusion about how to characterize the work of Jean-Jacques Rousseau. His thought has at various times been related to such dissimilar thinkers as Plato and Hobbes. From Plato he is said to have acquired his affinities for community and civic virtue. And one does not have to look too hard to find his praise for the great (...) sage of the Academy: "Plato only purified the heart of man."1 He was often eager to affiliate his ideas with those of antiquity. He yearned for modern society to rekindle the flames of a once-great civilization. "[W]hat keeps us [the moderns] from being men like them [the ancients]? Our prejudices, our base philosophy, and the passions of petty self-interest, concentrated together with egoism in all hearts by inept institutions in which genius never had any share."2 Despite his obvious admiration for the perceived greater ideas of the past, however, Rousseau also expressed some skepticism. James Miller has suggested that he held Plato's theory of the Forms to be unsustainable.3 Allan Bloom has likewise argued that Rousseau's "teaching is not... a revival of those of Plato.... If he admires the practice of antiquity, he does not accept the theory."4This has led many to argue that Rousseau is best understood as student of Thomas Hobbes. Roger D. Masters, for example, has suggested that "Rousseau's principles of political right can... be best described as a reformulation [End Page 383] of Hobbes' conception of the social contract."5 Arthur Melzer also argues, "The purpose of the doctrine Rousseau elaborates in the Social Contract is essentially the same [as Hobbes']."6 This view is argued on the grounds that the General Will is a positive or arbitrary standard, functioning as the primary principle of Rousseau's constructive political program. Yet the vision of Rousseau as a Hobbesian or modernist also merits skepticism. While he employs a social contract, as does Hobbes, he explicitly rejects traditional forms of positivism. "What is good and conformable to order is so by the nature of things and independently of human conventions."7 Whatever one might say about such passages, it at least raises the possibility that Rousseau is no modernist in the Straussian sense of defining Justice as human agreement.Much of what contributes to the conflicting interpretations of Rousseau can be attributed to different understandings of the relative priority and relationship of two central concepts in his writings. One of these is the well-discussed notion of the General Will. The dominant fashion is to read the General Will as a conventional substitute for natural law or transcendent Ideas. According to this reading, the General Will is grounded on nothing more than consent and functions as the first principle of all legitimate political societies. The other term central to Rousseau's program is the far less discussed but equally important concept of Justice. Little has been written on his understanding of Justice and, for that matter, he himself rarely discussed it explicitly. But it, too, could also be considered a primary principle. While it would be foolish to dismiss the importance of the General Will to Rousseau, it would be equally problematic to explore it independently of his Idea of Justice. The question in understanding his work is which of these two principles—the General Will or Justice—is primary or fundamental. If it is the General Will, a case can be made that the Straussians are right, and Rousseau is a positivist. If Justice is prior, on the other hand, then there is reason to believe that he was something much different.I argue that the positivist reading of Rousseau is flawed. Indeed, my thesis is that he is among the greatest and most thorough Platonists of the modern era.8 His rejection of Hobbes is not merely rhetorical. In fact, it represents the [End Page 384] true impetus of his social contract. This contract is designed explicitly to counter Hobbesian positivism. In the same way that Plato responds to Protagoras' positivism with his theory of the Forms, Rousseau responds to Hobbes... (shrink)

Like many recent works in legal theory, especially those focusing on the apparently conflicting schools of legal positivism and natural law, Waluchow’s Inclusive Legal Positivism begins by admitting a degree of perplexity about the field; indeed, he suggests that the field has fallen into “chaos”. Disturbingly, those working within legal theory appear most uncertain about what the tasks of their field are. Legal philosophers often seem to suspect strongly that at least their colleagues in the field are confused about those (...) tasks. As a result, many recent books in legal theory are in large part exercises in legal metatheory, devoting many pages to attempts to define the purposes and goals of the field. Waluchow follows this trend and begins by expressing a desire to clarify the issues that separate those trying to give an account of the nature of law. His ultimate goal is to defend a version of legal positivism, inclusive legal positivism, that he thinks is at least implicit in H. L. A. Hart’s work. (shrink)

Defends confrontational modes of citizenship as a means to reinvigorate democratic participation and regime accountability. A growing number of people are enraged about the quality and direction of public life, despise politicians, and are desperate for real political change. How can the contemporary neoliberal global political order be challenged and rebuilt in an egalitarian and humanitarian manner? What type of political agency and new political institutions are needed for this? In order to answer these questions, Confrontational Citizenship draws on a (...) broad base of perspectives to articulate the concept of confrontational citizenship. William W. Sokoloff defends extra-institutional and confrontational modes of political activity along with new ways of conceiving political institutions as a way to create political orders accountable to the people. In contrast to many forms of democratic theory, Sokoloff argues that confrontational modes of citizenship (e.g., protest) are good because they increase the accountability of a regime to the people, increase the legitimacy of regimes, lead to improvements in a political order, and serve as a means to vent frustration. The goal is to make the word citizen relevant and dangerous to the settled and closed practices that structure our political world and to provide a hopeful vision of what it means to be politically progressive today. William W. Sokoloff is Associate Professor of Political Science at the University of Texas, Rio Grande Valley. (shrink)

The paper problematises the reliability and ethics of using social media data, such as sourced from Twitter or Instagram, to carry out health-related research. As in many other domains, the opportunity to mine social media for information has been hailed as transformative for research on well-being and disease. Considerations around the fairness, responsibilities and accountabilities relating to using such data have often been set aside, on the understanding that as long as data were anonymised, no real ethical or scientific issue (...) would arise. We first counter this perception by emphasising that the use of social media data in health research can yield problematic and unethical results. We then provide a conceptualisation of methodological data fairness that can complement data management principles such as FAIR by enhancing the actionability of social media data for future research. We highlight the forms that methodological data fairness can take at different stages of the research process and identify practical steps through which researchers can ensure that their practices and outcomes are scientifically sound as well as fair to society at large. We conclude that making research data fair as well as FAIR is inextricably linked to concerns around the adequacy of data practices. The failure to act on those concerns raises serious ethical, methodological and epistemic issues with the knowledge and evidence that are being produced. (shrink)

PC Wars: Politics and Theory in the Academy addresses the very issue of political correctness and the current skirmishes in the culture wars. It includes statements from many of our leading contemporary public intellectuals, including Joan Wallach Scott, Michael Be;rube;, Bruce Robbins, Henry Giroux, and Gerald Graff. The collection marks a watershed in the debate about "pc" in that it presents serious considerations and analyses of the factors, causes, and consequences of the culture wars. Carefully examining the construction of "pc," (...) PC Wars analyses political correctness by focusing on the mass media, class politics, and the ideology of managerial democracy. It places the disputes around "pc" in the context of contemporary developments in critical and cultural theory and the current backlash against theory, manifested in the recent attacks on Marxism, feminism and deconstruction. The book also scrutinizes the undercurrents of anti-intellectualism and anti-professionalism which have tended to create a fertile ground for the "pc" hysteria. Offering much more than slogans and slinging arrows, PC Wars provides a spirited and critical look at the reaction, ideology, and political forces that have coalesced around the term. Contributors: Michael Be;rube;, Reed Way Dasenbrock, Frank Farmer, Henry Giroux, Gerald Graff, Darlene Hantzis and Devoney Looser, John S. Howard and James M.

Emilsen, William W On the cusp of the Second Vatican Council the distinguished American Lutheran historical theologian, Jaroslav Pelikan, then at the University of Chicago, published a groundbreaking volume titled The Riddle of Roman Catholicism. In this book Pelikan gave a sympathetic yet critical examination of the evolution of Roman Catholicism, its distinctive beliefs and, most importantly, he offered a discussion of the theological issues Protestants face in their conversations with Roman Catholics on Christian unity. The Riddle of Roman Catholicism (...) met an obvious need. It was quickly reprinted by Abingdon Press in the United States and published by Hodder and Stoughton in Great Britain the following year. It was also widely acclaimed in both the Protestant and Catholic presses. The Christian Century magazine, representing the voice of mainstream Protestantism in America, published excerpts from the book claiming that it 'sets the stage for realistic discussion of Christendom's sad divisions'. The Presbyterian theologian and ecumenist from Princeton, John A. Mackay, reviewed it in Theology Today as an 'outstanding book', 'the most significant to appear on Roman Catholicism in many years'. Daniel Walther, professor of church history at the Seventh-day Theological Seminary at Andrews University in Michigan extolled Pelikan's book as 'a significant omen of the new Protestant approach', one that attempted 'to end the "hot war" between the confessions'. Catholic scholars, too, were receptive. Bonaventure Schepers's review in the Thomist, for example, thanked Pelikan for his 'courage and honesty' and invited the journal's readers 'to rejoice with us at the appearance of his important work'. Gustave Wiegel's lengthy review in the Jesuit review, America, named it as 'probably the most important' of the many interesting Protestant studies of Roman Catholicism at the time. Although Pelikan was still a relatively young scholar at the time, The Riddle of Roman Catholicism established him as a serious thinker on the topic of Christian unity. (shrink)

Both Kant and James claim to limit the role of knowledge in order to make room for faith. In this paper, we argue that despite some similarities, their attempts to do this come apart. Our main claim is that, although both Kant and James justify our adopting religious beliefs on practical grounds, James believes that we can—and should—subsequently assess such beliefs on the basis of evidence. We offer our own account of this evidence and discuss what this difference means for (...) their accounts of religious belief. (shrink)

This article reports the findings of a survey examining if there are gender and career stage differences between male and female practitioners regarding ethical judgment. The results show that, on average, females adopted a more strict ethical stance than their male counterparts on 7 out of 19 vignettes. Males on the other hand, demonstrated a more ethical stance than their female counterparts on 2 out of 19 vignettes. The results furthermore indicate there is a significant difference in ethical judgment across (...) career stages. Overall, it appears that practitioners in later career stages display higher ethical judgment than practitoners in lower career stages. Implications are provided for both practitioners and academicians. (shrink)

This essay is concerned with Bernard Williams’ contention in Ethics and the Limits of Philosophy that, in ethics, reflection can destroy knowledge. I attempt to defend this contention from the charge of incoherence. I do this by taking seriously the idea that ethical knowledge is knowledge from an ethical point of view. There nevertheless remains an issue about whether the contention is consistent with ideas elsewhere in Williams’ own work, in particular with what he says about knowledge in (...) Descartes. In an earlier essay I argued that it is not. In a subsequent essay I indicated that I had changed my mind and gave a more sympathetic account of Williams’ contention. In this essay I set out the issues and say some more about my change of mind. (shrink)

Practically every contemporary mainstream scientist presumes that all aspects of mind are generated by brain activity. We demonstrate the inadequacy of this picture by assembling evidence for a variety of empirical phenomena which it cannot explain. We further show that an alternative picture developed by F. W. H. Myers and William James successfully accommodates these phenomena, ratifies the common sense view of ourselves as causally effective conscious agents, and is fully compatible with contemporary physics and neuroscience.

In the past two decades, reinforcement learning has become a popular framework for understanding brain function. A key component of RL models, prediction error, has been associated with neural signals throughout the brain, including subcortical nuclei, primary sensory cortices, and prefrontal cortex. Depending on the location in which activity is observed, the functional interpretation of prediction error may change: Prediction errors may reflect a discrepancy in the anticipated and actual value of reward, a signal indicating the salience or novelty of (...) a stimulus, and many other interpretations. Anterior cingulate cortex has long been recognized as a region involved in processing behavioral error, and recent computational models of the region have expanded this interpretation to include a more general role for the region in predicting likely events, broadly construed, and signaling deviations between expected and observed events. Ongoing modeling work investigating the interaction between ACC and additional regions involved in cognitive control suggests an even broader role for cingulate in computing a hierarchically structured surprise signal critical for learning models of the environment. The result is a predictive coding model of the frontal lobes, suggesting that predictive coding may be a unifying computational principle across the neocortex. (shrink)
