Good epistemic practices are essential to the well-functioning of organizations. Epistemic practices are adopted norms, policies, procedures, and general methodologies that further our epistemic aims or realize our epistemic values. This chapter argues for the importance of organizational good epistemic practices through an analysis of the failures of risk management implicated in JPMorgan’s notorious ‘London Whale’ trading losses, which roiled the financial markets in 2012. A number of these failures of risk management exemplified ways in which we, as fallible reasoners, (...) may be prone to error individually and collectively. Good epistemic practices inter alia anticipate and endeavor to correct for erroneous patterns of reasoning. They help guard against future epistemic failings, and they support good reasoning within and on the part of organizations. In so doing, they constitute some of the key structural elements of organizational epistemic virtues. (shrink)

This chapter provides an introduction to the emerging field of the philosophy of money and finance. The field addresses philosophical issues about the nature of money and the normative foundations of financial systems. Although philosophical theorizing about money and finance dates back to Antiquity, the topic has only recently emerged as a central research focus. The chapter also introduces the present anthology and locates its parts and chapters in the broader field. More specifically, the anthology is divided into four main (...) parts: Metaphysics, Epistemology, Ethics, and Political Philosophy. Each part contains four chapters on different but interrelated topics, which are all introduced here. (shrink)

Epistemic practices are an important but underappreciated component of business ethics; good conduct requires making epistemically sound as well as morally principled judgments. Well-founded judgments are promoted by epistemic virtues, and for organizations, epistemic virtues are arguably achieved through organizational good epistemic practices. But how are such practices to be developed? This paper addresses this normative and practical challenge. The first half of the paper explains what organizational good epistemic practices are and outlines a means for their construction. The second (...) half of the paper demonstrates how specific good epistemic practices could be developed by considering a case of corporate epistemic failings: JPMorgan’s notorious 2012 ‘London Whale’ trading losses. Following this, the paper briefly surveys the institutional epistemic failings of the 2008 global financial crisis and the remedial actions that they suggest. Although the discussion is focused on the banking industry, the main ideas, and some of the epistemic practices, generalize to organizations in other industries. (shrink)

This paper argues that a priori justification is, in principle, compatible with naturalism—if the a priori is understood in a way that is free of the inessential properties that, historically, have been associated with the concept. I argue that empirical indefeasibility is essential to the primary notion of the a priori ; however, the indefeasibility requirement should be interpreted in such a way that we can be fallibilist about apriori-justified claims. This fallibilist notion of the a priori accords with the (...) naturalist’s commitment to scientific methodology in that it allows for apriori-justified claims to be sensitive to further conceptual developments and the expansion of evidence. The fallibilist apriorist allows that an a priori claim is revisable in only a purely epistemic sense. This modal claim is weaker than what is required for a revisability thesis to establish empiricism, so fallibilist apriorism represents a distinct position. (shrink)

I argue that epistemic failings are a significant and underappreciated moral hazard in the financial services industry. I argue further that an analysis of these epistemic failings and their means of redress is best developed by identifying policies and procedures that are likely to facilitate good judgment. These policies and procedures are “best epistemic practices.” I explain how best epistemic practices support good reasoning, thereby facilitating accurate judgments about risk and reward. Failures to promote and adhere to best epistemic practices (...) contributed to the 2008 financial crisis. I identify and discuss some of the ways in which best epistemic practices were violated in the events that led to the crisis, with a focus on the role of the credit rating agencies. I go on to discuss some of the ways in which these failings have been redressed. I conclude by observing how proactive regulation for best epistemic practices might help us to anticipate and avoid future crises. (shrink)

A central feature of ordinary moral thought is that moral judgment is mind-independent in the following sense: judging something to be morally wrong does not thereby make it morally wrong. To deny this would be to accept a form of subjectivism. Neil Sinclair (2008) makes a novel attempt to show how expressivism is simultaneously committed to (1) an understanding of moral judgments as expressions of attitudes and (2) the rejection of subjectivism. In this paper, I discuss Sinclair’s defense of anti-subjectivist (...) moral mind-independence on behalf of the expressivist, and I argue that the account does not fully succeed. An examination of why it does not is instructive, and it reveals a fundamental dilemma for the expressivist. I offer a suggestion for how the expressivist might respond to the dilemma and so uphold Sinclair’s defense. (shrink)

Epistemology needs to account for the success of science. In True Enough, Catherine Elgin argues that a veritist epistemology is inadequate to this task. She advocates shifting epistemology’s focus away from true belief and toward understanding, and further, jettisoning truth from its privileged place in epistemological theorizing. Pace Elgin, I argue that epistemology’s accommodation of science does not require rejecting truth as the central epistemic value. Instead, it requires understanding veritism in an ecumenical way that acknowledges a rich array of (...) truth-oriented values. ¶ In place of veritism, Elgin offers a holistic epistemology that takes epistemic norms to have their genesis in our collective practice of deliberation. The acceptability of epistemic norms turns on epistemic responsibility, as opposed to reliability, and truth-conduciveness is rejected as the standard of evaluation for arguments and methods of inquiry. I argue, by way of an extended discussion of a high-profile and controversial criminal case, that this leaves epistemic practices and their products inadequately grounded. I offer an alternative, veritistic account of epistemic norms that retains a modified version of truth-conduciveness as a standard of evaluation. However, my alternative account of epistemic norms is congenial to Elgin’s holistic epistemology, and, I suggest, could be incorporated within it. (shrink)

Chinese philosophy has long recognized the importance of the body and emotions in extensive and diverse self-cultivation traditions. Philosophical debates about the relationship between mind and body are often described in terms of mind-body dualism and its opposite, monism or some kind of "holism." Monist or holist views agree on the unity of mind and body, but with much debate about what kind, whereas mind-body dualists take body and mind to be metaphysically distinct entities. The question is important for several (...) reasons. Several humanistic and scientific disciplines recognize embodiment as an important dimension of the human condition. One version, the problem of mind-body dualism, is central to the history of both philosophy and religion. Some account of relations between body and mind, spirit or soul is also central to any understanding of the self. Recent work in cognitive and neuroscience underscores the importance of our somatic experience for how we think and feel. (shrink)

This very short paper highlights some of my recent and forthcoming work on “good epistemic practices” in the financial services industry. It identifies some epistemic dimensions of risk management in banking and illustrates how managing for good epistemic practices might be helpful.

This article examines the epistemology of risk assessment in the context of financial modelling for the purposes of making loan underwriting decisions. A financing request for a company in the paper and pulp industry is considered in some detail. The paper and pulp industry was chosen because it is subject to some specific risks that have been identified and studied by bankers, investors and managers of paper and pulp companies and certain features of the industry enable analysts to quantify the (...) impact of specific risk events of a given dimension on a company's future financial performance. While companies in other industries may be subject to similar risk factors, the impact of risk events may be more difficult to gauge in those industries. The ability of financial analysts to model the impact of a risk event, and hence quantify a credit risk, increases the predictive accuracy of the model. I argue that bankers and regulators should recognise the uncertainty associated with unquantifiable credit risk in financial models, and they should view this uncertainty as a credit risk factor in and of itself. Evaluating the relative degree to which credit risk is quantifiable in financial models is a potentially significant yet largely unrecognised tool for credit risk management. I consider some possible applications of this assessment tool for managing risk within the banking industry. (shrink)

Broadly speaking, a naturalistic approach to epistemology seeks to explain human knowledge – and justification in particular – as a phenomenon in the natural world, in keeping with the tenets of naturalism. Naturalism is typically defined, in part, by a commitment to scientific method as the only legitimate means of attaining knowledge of the natural world. Naturalism is often thought to entail empiricism by virtue of this methodological commitment. However, scientific methods themselves may incorporate a priori elements, so empiricism does (...) not follow from the methodological commitments of naturalism alone. And given a suitably-naturalistic conception of the a priori, a priori forms of justification may be compatible with naturalism generally. A priori justification is, in principle, compatible with naturalism – and hence naturalistic epistemologies – if the a priori is understood in a way that is free of some of the inessential properties that have been associated with the concept. I argue that some of the more prominent strategies for accommodating normative notions within a naturalistic framework allow for the possibility of a priori justification. These include reliabilism, instrumental rationality, and nonfactualism about justification. A priori justification thus need not be seen as standing in opposition to all naturalistic epistemologies. It is only with nonnormative naturalistic epistemologies that a priori justification per se is incompatible, and this only because the notion of justification itself has no role to play within a nonnormative approach to epistemology.

Leonard Cohen’s celebrated song “Suzanne” exhibits a certain conception of self-awareness and intersubjectivity that is embraced by phenomenologists and some psychologists. A key element of this conception is that we have pre-reflective self-awareness, including and especially bodily self-awareness. We are tacitly and pre-reflectively aware of ourselves in experience. A second, related element concerns reflective functioning. Reflective functioning is the ability to appreciate oneself and others as being “minded,” that is to say, as having beliefs, desires, and emotions with intentional content. (...) Reflective functioning develops in the context of social relations. In particular, it is part of a maturational process that is activated in the context of parent-child relationships in which the adult “mirrors” the developing child’s experiences and feelings. In this essay, I consider how pre-reflective bodily awareness and reflective functioning, in combination with an appreciation of the epistemic value of love, can help us to comprehend what it is to “touch a perfect body with a mind.” I also explain why, even if we come to fully understand the workings of reflective functioning, the mirror will retain its mystery.

I give a brief overview of Albert Casullo’s Essays on A Priori Knowledge and Justification, followed by a summary of his diagnostic framework for evaluating accounts of a priori knowledge and a priori justification. I then discuss Casullo’s strategy for countering deficiency arguments against empiricism. A deficiency argument against empiricism can be countered by mounting a parallel argument against moderate rationalism that shows moderate rationalism to be defective in a similar way. I argue that a particular deficiency argument put forth (...) by George Bealer in “The Incoherence of Empiricism” can withstand a parallel challenge mounted by Casullo.I then consider Casullo’s preferred analysis of the concept of a priori justification, which identifies a belief’s being justified by some nonexperiential source as the feature by virtue of which it is justified a priori. On the analysis, an apriori-justfied belief that is justified to a degree that is sufficient for knowledge is not taken to be empirically indefeasible. I argue that Casullo could avail himself of an empirical indefeasibility requirement that is consistent with his minimal and fallibilist conception of a priori knowledge. Doing so would capture a feature of the concept of a priori knowledge that is of particular interest and significance. (shrink)

This is an imagined dialogue between one of the more famous skeptics regarding moral attribution, Thrasymachus, and an imagined Socrates who, through the convenient miracle of time travel, returns to Athens after exposure to contemporary metaethics, now a devoted and formidable quasi-realist expressivist. The dialogue focuses on the characterization of moral conflict and moral justification available to the expressivist, and the authors attempt to lay out the distinctive strengths and weaknesses of the expressivist view.

Knowing Words will be welcomed by sinologists, classicists, and scholars of comparative philosophy and literature.

: The semantic fields and root metaphors of "fate" in Classical Greece and pre-Buddhist China are surveyed here. The Chinese material focuses on the Warring States, the Han, and the reinvention of the earlier lexicon in contemporary Chinese terms for such concepts as risk, randomness, and (statistical) chance. The Greek study focuses on Homer, Parmenides, the problem of fate and necessity, Platonic daimons, and the "On Fate" topos in Hellenistic Greece. The study ends with a brief comparative metaphorology of metaphors (...) for the action of fate including command, division or allotment, and wheel or cycles of change. (shrink)

This collection illustrates the centrality of skill within ancient ethics, including ancient Chinese ethics, showing how skill or techne has been a touchstone from the beginning of philosophical thought. Covering Socrates' search for expertise in virtue, the Republic's 'craft of justice', Aristotle's delineation of the politike techne and the Stoics' 'art of life'. Divided into four sections on Plato, Aristotle, the Stoics and Chinese ethics, it brings together world-leading philosophers working across this broad topic. Yet it is not limited to (...) traditional figures and traditions, featuring essays on the importance of skill in lesser-known philosophers, such as Carneades and Antipater, and texts, such as the Zhuangzi. In doing so, it illustrates how skill, expertise and 'know how' are important in ethics, epistemology, philosophy of mind, philosophy of action and cognitive science. This collection of specially-commissioned chapters is the first to foreground skill as central to Ancient and Chinese ethics specifically making it an essential for anyone interested in the value of cross-cultural philosophy today.

Reasoning well about risk is most challenging when a woman is pregnant, for patient and doctor alike. During pregnancy, we tend to note the risks of medical interventions without adequately noting those of failing to intervene, yet when it's time to give birth, interventions are seldom questioned, even when they don't work. Meanwhile, outside the clinic, advice given to pregnant women on how to stay healthy in everyday life can seem capricious and overly cautious. This kind of reasoning reflects fear, (...) not evidence. (shrink)

Critical congenital heart disease screening is rapidly becoming the standard of care in the United States after being added to the Recommended Uniform Screening Panel in 2011. Newborn screens typically do not require affirmative parental consent. In fact, most states allow parents to exempt their baby from receiving the required screen on the basis of religious or personally held beliefs. There are many ethical considerations implicated with allowing parents to exempt their child from newborn screening for CCHD. Considerations include the (...) treatment of religious exemptions in our current legal system, as well as medical and ethical principles in relation to the rights of infants. Although there are significant benefits to screening newborns for CCHD, when a parent refuses for religious or personal beliefs, in the case of CCHD screening, the parental decision should stand.

Introduction to a special issue on unrealistic optimism.

Does asking about trauma history create participant distress? If so, how does it compare with reactions to other personal questions? Do participants consider trauma questions important compared to other personal questions? Using 2 undergraduate samples (Ns = 240 and 277), the authors compared participants' reactions to trauma questions with their reactions to other possibly invasive questions through a self-report survey. Trauma questions caused relatively minimal distress and were perceived as having greater importance and greater cost-benefit ratings compared to other kinds (...) of psychological research in an undergraduate human subjects pool population. These findings suggest that at least some kinds of trauma research appear to pose minimal risk when compared to other minimal risk research topics, and that participants recognize the importance of research about trauma.

A key debate about the nature and role of ecommerce centres around the question of whether it is merely an old activity in a new form, or a discontinuous process that rewrites the ideas and assumptions of the ‘old’ economy. The objective of this exploratory and qualitative study is to shed some light on this issue through the lens of business ethics. We will examine whether established ethical principles still apply to e‐commerce, or instead if the ‘rule book’ now needs (...) to be re‐written. (shrink)

Autobiographical stories do not merely offer insights into someone’s experience but can constitute evidence or even serve as self-standing arguments for a given viewpoint in the context of public debates. Such stories are likely to exercise considerable influence on debate participants’ views and behaviour due to their being more vivid, engaging, and accessible than other forms of evidence or argument. In this paper we are interested in whether there are epistemic and moral duties associated with the use of autobiographical stories (...) in mental health debates. We argue that debate participants have a responsibility to assess a story as evidence or as an argument when the story is put forward to support a given viewpoint. We also make some preliminary suggestions about what can be done to ensure that the use of stories contributes to the variety of the resources available to debate participants without compromising the quality of the argumentation or increasing polarisation.

This paper details the experience of planning, orchestrating, teaching, and participating in a writing-intensive, team-taught, introductory philosophy class designed to expand the diversity of voices included in philosophical study. Accordingly, this article includes the various perspectives of faculty, TAs, and students in the class. Faculty authors discuss the administrative side of the course, including its planning and goals, its texts and structure, its working definition of “philosophy,” its balance of canonical and non-canonical texts, the significant resistance met in getting the (...) course approved, the complex pedagogical difficulties that attend teaching non-canonical texts, the motivation and execution of the course’s writing-intensive dimension, and a summary of student evaluations of the course. The TA authors reflect on the high level of student engagement and interest compared to other introductory philosophy courses, the perception that students found the material highly relevant to their own lives, and the capacity of the material to bring about philosophical insight for the instructors in the class. The student author offers a favorable account of the class and remarks on how the structure of the course aided the accessibility and relevance of the texts. (shrink)

In this piece, we articulate the "collaborative autoethnographic practice" we utilized to illustrate the complexities of mothering that involved: (a) individually writing autoethnographic narratives on mothering, (b) sharing these autoethnographic narratives in a public forum, (c) publicly discussing the heuristic commonalities across these autoethnographic narratives, (d) tying those commonalities back to the literature, and (e) revisiting the autoethnographic narratives for aspects of social critique where our autoethnographic narratives (intentionally or unintentionally) hegemonicaly reproduced cultural scripts. We argue that presenting knowledge of (...) mothering in this way, through collaborative autoethnographic practice, creates a myriad of opportunities for growth and self-reflexivity, and our stories illuminate a part of our existence that often remains unexamined in other methodologies.

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

BackgroundMulti-centre studies generally cost more than single-centre studies because of larger sample sizes and the need for multiple ethical approvals. Multi-centre studies include clinical trials, clinical quality registries, observational studies and implementation studies. We examined the costs of two large Australian multi-centre studies in obtaining ethical and site-specific approvals.MethodsWe collected data on staff time spent on approvals and expressed the overall cost as a percent of the total budget.ResultsThe total costs of gaining approval were 38 % of the budget for (...) a study of 50 centres (mean cost AUD $6960 per site) and 2 % for a study of 11 centres (mean cost AUD $2300 per site). Seventy-five and 90 % of time was spent on repeated tasks, respectively, and many time-consuming tasks, such as reformatting documents, did nothing to improve the study design or participant safety.ConclusionsImprovements have been made to the ethical approval application system, but more gains could be made without increasing risks of harm to research participants. We propose that ethical review bodies and individual sites publish statistics on how long they take to process approvals which could then be nationally benchmarked. (shrink)

Over the last several years, as cesarean deliveries have grown increasingly common, there has been a great deal of public and professional interest in the phenomenon of women 'choosing' to deliver by cesarean section in the absence of any specific medical indication. The issue has sparked intense conversation, as it raises questions about the nature of autonomy in birth. Whereas mainstream bioethical discourse is used to associating autonomy with having a large array of choices, this conception of autonomy does not (...) seem adequate to capture concerns and intuitions that have a strong grip outside this discourse. An empirical and conceptual exploration of how delivery decisions ought to be negotiated must be guided by a rich understanding of women's agency and its placement within a complicated set of cultural meanings and pressures surrounding birth. It is too early to be 'for' or 'against' women's access to cesarean delivery in the absence of traditional medical indications – and indeed, a simple pro- or con- position is never going to do justice to the subtlety of the issue. The right question is not whether women ought to be allowed to choose their delivery approach but, rather, taking the value of women's autonomy in decision-making around birth as a given, what sorts of guidelines, practices, and social conditions will best promote and protect women's full inclusion in a safe and positive birth process.

Person‐specific evidence was developed as a grounded theory by analyzing 20 selected case descriptions from interventions using the guided self‐determination method with people with various long‐term health conditions. It explains the mechanisms of mobilizing relational capacity by including person‐specific evidence in shared decision‐making. Person‐specific self‐insight was the first step, achieved as individuals completed reflection sheets enabling them to clarify their personal values and identify actions or omissions related to self‐management challenges. This step paved the way for sharing these insights and (...) challenges in a relationship with a supportive health professional, who could then rely on person‐specific evidence instead of assumptions or a narrow disease perspective for shared decision‐making. Trust in the evidence encouraged the supportive health professional to transfer it to the interdisciplinary team. Person‐specific evidence then enhanced the ability of team members to apply general evidence in a meaningful way. The increased openness achieved by individuals through these steps enabled them to eventually share their new self‐insights in daily life with other people, decreasing loneliness they experienced in self‐management. Relational capacity, the core of the theory, is mobilized in both people with long‐term health conditions and healthcare professionals. Further research on person‐specific evidence and relational capacity in healthcare is recommended. (shrink)

Background: Nurses and midwives have a professional obligation to promote health and prevent disease, and therefore they have an essential role to play in vaccination. Despite this, some nurses and midwives have been found to take an anti-vaccination stance and promulgate misinformation about vaccines, often using Facebook as a platform to do so. Research question: This article reports on one component and dataset from a larger study – ‘the positives, perils and pitfalls of Facebook for nurses’. It explores the specific (...) issue of nurses and midwives who take an anti-vaccination stance, deemed to be unprofessional by crossing professional boundaries and by providing medical information on Facebook that is not within their scope of practice. Participants: Data were collected via an online worldwide survey from nurse and midwife participants, distributed and ‘snowballed’ through relevant nursing and midwifery groups on Facebook. In total, 1644 Registered Nurses and Midwives, and Enrolled Nurses worldwide attempted the online survey. There were 1100 completed surveys and 54 partially completed surveys. Semi-structured interviews were also conducted online using Skype® with 17 participants in Australia. Ethical considerations: Ethical processes and procedures have been adhered to relating to privacy, confidentiality and anonymity of the participants. Findings/results: A mixed-methods approach was used, including descriptive and content analysis of the quantitative survey data and thematic analysis of the qualitative interview data. The main theme ‘blurred boundaries’ was generated, which comprised three sub-themes: ‘follow the science, ‘abuse of power and erosion of trust’ and ‘the moral and ethical responsibility to safeguard public health’. The results offer an important and unique understanding of how nurses and midwives interpret the conduct of fellow health professionals as unprofessional and crossing the professional boundary if they used Facebook to promulgate anti-vaccination messages and/or give medical advice online. Conclusion: There are many positives and negatives for nurses and midwives associated with using Facebook for personal and professional communication, which is in keeping with the results of the larger study from which this article is taken. Professional behaviour is a key theme in the larger research as is the ethical construct of ‘every act has a consequence’; however, in this article, the theme ‘blurred boundaries’ offers an overall understanding of how nurses and midwives interpret the behaviour of their colleagues who espouse anti-vaccination sentiment and/or give medical advice online that is outside their scope of practice and education.
