Existing literature on counterproductive work behaviors (CWBs) has focused on the influence that interpersonal and organizational factors have on predicting said behavior. However, more recent studies have begun to explore the dimensionality of CWB in relation to the likelihood of coworkers reporting coworkers’ CWBs. Likelihood of reporting CWB across various types of CWB, and the relationships between self-reported CWB were assessed across two studies. The studies did so utilizing two different measures of CWB and two different measures of CWB reporting, (...) and found very similar results. Results suggest those employees who report one type of CWB behavior would also be more willing to report other types of CWBs, and those who have lower self-reported CWB are more likely to report CWB.

Prevention focus is a self-regulatory orientation that serves the need for security, and promotion focus is a self-regulatory orientation that serves the need for growth. From mid-March to early April 2020, did people judge prevention focus to be more useful than promotion focus for responding to COVID-19? Our study tested and showed support for this hypothesis with 401 American and Canadian participants, who we sampled in 100-person waves on the first four Thursdays of the pandemic. For this study, we developed (...) a new measure of the judged usefulness of promotion and prevention focus. Additionally, results showed that the judged usefulness of promotion and prevention focus related positively to support of the psychological needs for autonomy and relatedness, respectively, in responding to COVID-19. Exploratory analyses showed that day-to-day differences in autonomy, competence, and relatedness support and in promotion and prevention focus tended to be small, which is notable given the large-scale changes to social distancing, employment, and media coverage of the virus during this time. Our research could be useful for crafting persuasive advocacy and narrative communications that encourage social distancing to protect others about whom people care most. (shrink)

Numerous major holidays celebrate socially gathering in person. However, in major holidays that happened during the pandemic, desires to nurture relationships and maintain holiday traditions often conflicted with physical distancing and other measures to protect against COVID-19. The current research sought to understand wellbeing during American Thanksgiving in 2020, which happened 8months into the COVID-19 pandemic, after months of physical distancing and stay-at-home orders. American Thanksgiving is a major holiday not limited to any religion. We asked 404 American adults how (...) they spent Thanksgiving Day and to report on their experiences of that day. Predictors of wellbeing that we drew from self-determination theory were satisfaction of the fundamental needs for social connection, for doing what one really wants, and feeling effective. The predictors of wellbeing that we drew from regulatory focus theory were a focus on growth, and a focus on security. We found that feeling socially connected and focusing on growth related most strongly to wellbeing. Additionally, participants who saw even one other person face-to-face reported significantly higher relatedness satisfaction, promotion focus, and wellbeing than those who did not. Our research could help construct persuasive messages that encourage nurturing close relationships at major holidays while remaining safe against the virus. (shrink)

The practice of modern craniomaxillofacial surgery has been defined by emergent technologies allowing for the acquisition, storage, utilization, and transfer of massive amounts of sensitive and identifiable patient data. This alone has thrust providers into an unlikely and unprecedented role as the stewards of vast databases of digital information. This data powers the potent surgical tool of virtual surgical planning, a method by which craniomaxillofacial surgeons plan and simulate procedural outcomes in a digital environment. Further complicating this new terrain is (...) the involvement of third‐party contractors—a necessary presence in bringing raw data to bear in the office, virtual space, and operating room. The individual privileges and responsibilities of patients, providers, and vendors towards data are situated within the most recent U.S. court rulings and regulations. This paper offers guidance for overseeing the safe and responsible transfer to third‐party contractors, and provides suggestions for negotiating the trinary relationship between physicians, their patients, and the vendors offering this transformative technology.

Higher order cognitive processes, including ethical decision making (EDM), are influenced by the experiencing of discrete emotions. Recent research highlights the negative influence one such emotion, anger, has on EDM and its underlying processes. The mechanism, however, by which anger disrupts the EDM has not been investigated. The current study sought to discover whether cognitive appraisals of an emotion-evoking event are the driving mechanisms behind the influence of anger on EDM. One primary (goal obstacle) and one secondary (certainty) appraisal of (...) anger were examined. Study results suggest that appraisals of certainty are the driving mechanism behind the negative relationship between anger and EDM. Certainty appraisals led to less application of EDM-promoting strategies and more unethical social motives. Findings further highlight the value of investigating appraisals of emotional events, given their cognitive nature, for their potential effects on cognitive operations, such as EDM. Future directions and implications are discussed. (shrink)

The 1980s witnessed a dramatic increase in hostile takeovers in the United States. Proponents argue that well- planned mergers enhance the value of the firm and the value of the firm to society. Critics typically argue that undesired takeovers ultimately harm society due to external costs not borne by the acquiring firm. To be socially responsible, the manager must consider the effects of the merger/acquisition on all stakeholders. Different traditional ethical frameworks for decision making are proposed and reviewed. A model (...) is proposed. (shrink)

We might suppose it is not only instrumentally valuable for beliefs to be true, but that it is intrinsically valuable – truth makes a non-derivative, positive contribution to a belief's overall value. Some intrinsic goods are better than others, though, and this article considers the question of how good truth is, compared to other intrinsic goods. I argue that truth is the worst of all intrinsic goods; every other intrinsic good is better than it. I also suggest the best explanation (...) for truth's inferiority is that it is not really an intrinsic good at all. It is intrinsically neutral. (shrink)

The following four assumptions plausibly describe the ideal rational agent. (1) She knows what her beliefs are. (2) She desires to believe only truths. (3) Whenever she desires that P → Q and knows that P, she desires that Q. (4) She does not both desire that P and desire that ~P, for any P. Although the assumptions are plausible, they have an implausible consequence. They imply that the ideal rational agent does not believe and desire contradictory propositions. She neither (...) desires the world to be any different than she thinks it is, nor thinks it is any different than she desires it to be. The problem of preserving our intuitions about desire, without embracing the implausible conclusion, is what I call “the Wishful Thinking Puzzle.” In this paper, I examine how this puzzle arises, and I argue that it is surprisingly difficult to solve. Even the decision theoretic conception of desire is not immune to the puzzle. One approach, the contrastive conception of desire, does avoid the puzzle without being ad hoc, but it remains too inchoate to win our full confidence. (shrink)

Several of the contributions to the Lynch et al. Special issue make the claim that conversation-analytic research into epistemics is ‘routinely crafted at the expense of actual, produced and constitutive detail, and what that detail may show us’. Here, we seek to address the inappositeness of this critique by tracing precisely how it is that recognizable actions emerge from distinct practices of interaction. We begin by reviewing some of the foundational tenets of conversation-analytic theory and method – including the relationship (...) between position and composition, and the making of collections – as these appear to be primary sources of confusion for many of the contributors to the Lynch et al. Special Issue. We then target some of the specific arguments presented in the Special Issue, including the alleged ‘over-hearer’s’ writing of metrics, the provision of so-called ‘alternative’ analyses and the supposed ‘crafting’ of generalizations in epistemics research. In addition, in light of Lynch’s more general assertion that conversation analysis has recently been experiencing a ‘rapprochement’ with what he disparagingly refers to as the ‘juggernaut’ of linguistics, we discuss the specific expertise that linguists have to offer in analyzing particular sorts of interactional detail. The article as a whole thus illustrates that, rather than being produced ‘at the expense of actual, produced and constitutive detail’, conversation-analytic findings – including its work in epistemics – are unambiguously anchored in such detail. We conclude by offering our comments as to the link between CA and linguistics more generally, arguing that this relationship has long proven to be – and indeed continues to be – a mutually beneficial one.

In this paper, we consider the implications of Grace de Laguna and Joel Katzav's work for the charge of conservatism against the analytic tradition. We differentiate that conservatism into three kinds: starting place; path dependency; and modesty. We also think again about gender in philosophy, consider the positive account of speculative philosophy presented by de Laguna and Katzav in comparison to some other naturalist trajectories, and conclude with a brief Australian addendum that reflects on a similar period in our own (...) country which was also associated with the professional institutionalisation of analytic philosophy.

This paper offers an interpretation of Plato's argument in Republic V that lovers of sights and sounds can have only opinion, and philosophers alone have legitimate claims to knowledge. The argument depends on the idea that knowledge is "set over what is" while mere opinion is "set over what is and is not." I argue for an enhanced veridical interpretation of 'to be' in this passage, on which 'what is' means, roughly, "what is so." Given a distinction between what is (...) so independently of how things seem and what is so partly in virtue of how things seem, I interpret the argument as an attempt to show that philosophers, who attend to what is so independently of how things seem, have knowledge, while the lovers of sights and sound have mere opinion because they attend not to how things are independently of how they seem, but only to how they are in virtue of how they seem.

Case-based instruction is a stable feature of ethics education, however, little is known about the attributes of the cases that make them effective. Emotions are an inherent part of ethical decision-making and one source of information actively stored in case-based knowledge, making them an attribute of cases that likely facilitates case-based learning. Emotions also make cases more realistic, an essential component for effective case-based instruction. The purpose of this study was to investigate the influence of emotional case content, and complementary (...) socio-relational case content, on case-based knowledge acquisition and transfer on future ethical decision-making tasks. Study findings suggest that emotional case content stimulates retention of cases and facilitates transfer of ethical decision-making principles demonstrated in cases. (shrink)

ABSTRACT: Epistemic duties would be duties to believe, disbelieve, or withhold judgement from propositions, and they would be grounded in purely evidential considerations. I offer a new argument for the claim that there are no epistemic duties. Though people may have duties to believe, disbelieve, or withhold judgement from propositions, those duties are never grounded in purely epistemic considerations. Rather, allegedly epistemic duties are a species of moral duty.RÉSUMÉ: Les fonctions épistémiques sont censées désigner le fait de croire ou de (...) ne pas croire des propositions, ou de suspendre notre jugement, et seraient fondées uniquement sur la prise en compte de l’évidence. Je présente un nouvel argument soutenant que les fonctions épistémiques n’existent pas. Bien que nous devions recourir aux fonctions de croire ou de ne pas croire des propositions, ou de suspendre notre jugement, ces fonctions ne sont jamais fondées sur d’uniques considérations épistémiques. Ce que l’on reconnaît comme des fonctions épistémiques appartient plutôt à l’espèce des fonctions morales. (shrink)

In recent years, the construct of character has received substantial attention among developmental scientists, but no consensus exists about the content and structure of character, especially among children and early adolescents. In a study of positive development among racially diverse Cub Scouts in the greater Philadelphia area, we assessed the construct and concurrent validity of a new measure of character, the Assessment of Character in Children and Early Adolescents, among 906 Scouts and 775 non-Scout boys and girls. We identified an (...) eight-correlated-factor model as providing the best fit with our data. We further established measurement invariance and explored latent mean differences for ACCEA scores across two Scout groups, non-Scout boys and non-Scout girls. Girls were generally superior than boys on all character attributes. We further examined concurrent validity of ACCEA by correlating the character attributes with youth sense of school competence, intentional self-regulation and parental perception of youth school performance. We discuss implications for future character research and point to the value of the ACCEA measure being used by practitioners in character development programs. (shrink)

An epistemic duty would be a duty to believe, disbelieve, or withhold judgment from a proposition, and it would be grounded in purely evidential or epistemic considerations. If I promise to believe it is raining, my duty to believe is not epistemic. If my evidence is so good that, in light of it alone, I ought to believe it is raining, then my duty to believe supposedly is epistemic. I offer a new argument for the claim that there are no (...) epistemic duties. Though people do sometimes have duties to believe, disbelieve, or withhold judgment from propositions, those duties are never grounded in purely epistemic considerations. (shrink)

This book explains the Problem of Truth’s Value and offers a virtue-theoretic solution to it. The Problem of Truth’s Value arises because it is hard to reconcile good theories of truth’s nature with good theories of why we should value truth. Some theories build value into the very nature of truth, but they tend to obscure the connection between what is true and how things are in the world. Other theories treat truth as a purely descriptive feature of claims. They (...) struggle to explain how such a feature could make something good or right to believe. To solve the problem, this book proposes a “Strong Virtue Theory” of truth’s value. On that theory, truth is worth caring about, but not because of any pre-existing value that inheres in states of true belief. Instead, truth is worth caring about because caring about truth is a moral virtue; it is part of being a morally good person. The book offers an account of Truthfulness as a moral virtue, independent of any value that inheres in states of true belief. It also criticizes several alternative ways of explaining truth’s value. Those alternatives include the idea that truth is inherently normative, the idea that truth makes beliefs intrinsically or instrumentally valuable, and the idea that truth confers a special sort of “epistemic value” on beliefs.

According to a prominent objection, deflationist theories of truth can’t account for the explanatory connection between true belief and successful action [Putnam 1978]. Canonical responses to the objection show how to reformulate truth-involving explanations of particular successful actions to omit any mention of truth [Horwich 1998]. According to recent critics, though, the canonical strategy misses the point. The deflated paraphrases lack the generality or explanatory robustness of the original explanatory appeals to truth [Kitcher 2002; Lynch 2009; Gamester 2018]. This article (...) diagnoses the canonical response’s failure and shows how deflationists can make sense of appeals to truth in explaining practical success, in all their generality and robustness, without construing truth as a substantial property.

This paper argues against the realization principle, which reifies the realization relation between lower-level and higher-level properties. It begins with a review of some principles of naturalistic metaphysics. Then it criticizes some likely reasons for embracing the realization principle, and finally it argues against the principle directly. The most likely reasons for embracing the principle depend on the dubious assumption that special science theories cannot be true unless special science predicates designate properties. The principle itself turns out to be false (...) because the realization relation fails the naturalistic test for reality: it makes no causal difference to the world.Footnote11This paper resulted from work done at John Heil's 2006 Mind and Metaphysics NEH Summer Seminar at Washington University in St. Louis. An early version of it was presented in a special symposium on realization at the 2007 meeting of the Southern Society for Philosophy and Psychology. I owe thanks to all the participants in both events for helpful discussions, and I owe particular thanks to Ken Aizawa, Torin Alter, Jason Ford, Carl Gillett, John Heil, Nicholas Helms, Pete Mandik, John Post, Gene Witmer, Michelle Wrenn, Tad Zawidzki, and two anonymous referees for the AJP.

Since its original publication in France in 1963, Pierre Hadot's lively philosophical portrait of Plotinus remains the preeminent introduction to the man and his thought. Michael Chase's lucid translation—complete with a useful chronology and analytical bibliography—at last makes this book available to the English-speaking world. Hadot carefully examines Plotinus's views on the self, existence, love, virtue, gentleness, and solitude. He shows that Plotinus, like other philosophers of his day, believed that Plato and Aristotle had already articulated the essential truths; (...) for him, the purpose of practicing philosophy was not to profess new truths but to engage in spiritual exercises so as to live philosophically. Seen in this light, Plotinus's counsel against fixation on the body and all earthly matters stemmed not from disgust or fear, but rather from his awareness of the negative effect that bodily preoccupation and material concern could have on spiritual exercises.

This paper argues against the almost universally held view that truth is an instrumentally valuable property of beliefs. For truth to be instrumentally valuable in the way usually supposed, it must play a causal role in the satisfaction of our desires. As it happens, truth can play no such role, because it is screened off from causal relevance by some of the truth-like properties first discussed by Stephen Stich. Because it is not causally relevant to the success of our actions, (...) truth is not instrumentally valuable in the way usually supposed. (shrink)

Preview: 2020, the year the coronavirus pandemic spread globally, marked the twenty-fifth year since the publication of Pierre Hadot’s work Philosophy as a Way of Life. In that time, what began as the research specialization of just a few scholars has become a growing area of philosophical and metaphilosophical inquiry, bringing together researchers from around the globe. Hadot’s key ideas of spiritual exercises, and the very idea of PWL, have been applied to a host of individual thinkers from across the (...) history of philosophy: from the Hellenistic and Roman-era philosophers of direct concern to Hadot, through renaissance thinkers like Petrarch, Lipsius, Montaigne, Descartes, or Bacon, into nineteenth-century thinkers led by Schopenhauer, Kierkegaard, and Nietzsche.In more recent years, more global reflections on the “very idea” of PWL have begun to emerge, as well as dedicated journal editions. In these more recent PWL studies, some of the manifold research questions have begun to be explored, which were opened up by the studies of Pierre and Ilsetraut Hadot, as well as its reception in Michel Foucault’s later work. What implications, after all, does understanding the history of PWL, and the predominance of this metaphilosophical conception in the history of Western thought, have for how we understand the practice of philosophy today? Does recovering the alternative understandings of philosophy as a practice in history necessarily lead to a criticism of contemporary, solely academic or theoretical modes of philosophizing, or is the idea of PWL one which has only historiographical force?

According to strong pluralist theories of truth, ‘true’ designates different properties depending on which sentences it’s applied to. An influential objection to strong pluralism claims it can’t make sense of logically complex sentences whose components have different truth-properties. For example, if ‘true’ designates correspondents for ‘Tabby is a cat’, and it designates coherence for ‘Tabby is beautiful’, what does it designate for ‘Tabby is a beautiful cat’ (Tappolet 1997)? Will Gamester (2019) has proposed a novel pluralist theory meant to avoid (...) the problem. The theory construes ‘true’ as designating a different property for each possible logical structure, and he has challenged monists to identify shortcomings of the theory in virtue of its pluralism. This paper answers Gamester’s challenge and identifies three such shortcomings. (1) The theory can’t make sense of the idea that all true conjunctions share the property of having true conjuncts, in virtue of which they are true. (2) The theory imposes unmotivated syntactic constraints on the language in which the theory of truth is formulated. (3) Avoiding the second shortcoming requires arbitrary choices among equally good candidates for “the” logical form of sentences and hence the designation of ‘true’ as applied to them. (shrink)

Laurence BonJour has recently proposed a novel and interesting approach to the problem of induction. He grants that it is contingent, and so not a priori, that our patterns of inductive inference are reliable. Nevertheless, he claims, it is necessary and a priori that those patterns are highly likely to be reliable, and that is enough to ground an a priori justification induction. This paper examines an important defect in BonJour's proposal. Once we make sense of the claim that inductive (...) inference is "necessarily highly likely" to be reliable, we find that it is not knowable a priori after all. (shrink)

One of his six introductions to philosophy, widely used by students in Alexandria, Ammonius' lecture on Porphyry was recorded in writing by his students in the commentary translated here. Along with five other types of introductions (three of which are translated in the Ancient Commentators on Aristotle volume Elias and David: Introductions to Philosophy with Olympiodorus: Introduction to Logic) it made Greek philosophy more accessible to other cultures. These introductions became standard in Ammonius' school and included a popular set of (...) five or more definitions of philosophy, some of them drawn from commentaries on quite different works. Ammonius' lecture expounded the most celebrated and discussed previous introduction written by Porphyry 200 years earlier, which was devoted to five main technical terms of Aristotle's logic. Ammonius was sympathetic to Porphyry because they both sought to harmonise the views of Plato and Aristotle with each other, arguing in different ways that the two philosophers did not disagree about the nature of universals. Porphyry's introduction was a hugely influential work for centuries after its composition, and this commentary by Ammonius served to maintain its position at the centre of later schools of philosophy. This English translation of Ammonius' work is the latest volume in the Ancient Commentators on Aristotle series and makes this philosophical work accessible to a modern readership. The translation is accompanied by an introduction, comprehensive commentary notes, bibliography, glossary of translated terms and a subject index. (shrink)

The author argues that ancient Skepticism may be most suited to deal with two crises in the Age of COVID-19: both the physical or epidemiological aspects of the pandemic, and the epistemological and ethical crisis of increasing disbelief in the sciences. Following Michel Bitbol, I suggest one way to mitigate this crisis of faith may be for science to become more epistemically modest, renouncing some of its claims to describe reality as it objectively is, and adopting an “intransitive” rather than (...) a “transitive” approach to Nature. This was the attitude adopted by the Greco-Roman medical school of the Empirics, which may also be of assistance in combatting the urgent problem of Fake News. The epistemology of Skepticism and the scientific methodology of the closely related Medical Empiricism shows that an epistemically modest, non-interventionist approach to science is quite compatible with a robust and sophisticated proto-experimental scientific methodology.

The core of alethic pluralism is the idea that truth is a different property in some discourses from others. Orthodox pluralists such as Crispin Wright and Michael Lynch share three commitments that motivate their view. One is Ecumenicalism, the view that scientific and moral claims are both truth-apt. The second is Occasional Realism, the view that truth in science is a matter of justification-independent, accurate representation, while truth in ethics is a matter of ideal epistemic justifiability. The third is Normativism, (...) the view that truth-attributions are normative in a way deflationary theories cannot accommodate. This paper articulates the “aletheiological dilemma” for orthodox pluralists. The dilemma arises when we ask whether the truth-property relevant to truth-attributions is epistemic. Occasional Realism requires it not be, but Normativism and the pluralists’ other commitments require truth for truth-attributions to be a matter of ideal justifiability. The paper also considers some ways around the dilemma, none of which looks very promising for pluralists. (shrink)

What is truth? Is there anything that all truths have in common that makes them true rather than false? Is truth independent of human thought, or does it depend in some way on what we believe or what we would be justified in believing? In what sense, if any, is it better for beliefs or statements to be true than to be false? In this engaging and accessible new introduction Chase Wrenn surveys a variety of theories of the nature (...) of truth and evaluates their philosophical costs and benefits. Paying particular attention to how the theories accommodate realist intuitions and make sense of truth’s value, he discusses a full range of theories from classical correspondence to relatively new deflationary and pluralist accounts. The book provides a clear, non-technical entry point to contemporary debates about truth for non-specialists. Specialists will also find new contributions to those debates, including a new argument for the superiority of deflationism to causal correspondence and pluralist theories. Drawing on a range of traditional and contemporary debates, this book will be of interest to students and scholars alike and anyone interested in the nature and value of truth. (shrink)

Forty years of experimentation on class inclusion and its probabilistic relatives have led to inconsistent results and conclusions about human reasoning. Recent research on the conjunction "fallacy" recapitulates this history. In contrast to previous results, we found that a majority of participants adhere to class inclusion in the classic Linda problem. We outline a theoretical framework that attributes the contradictory results to differences in statistical sophistication and to differences in response mode-whether participants are asked for probability estimates or ranks-and propose (...) two precise cognitive algorithms for ranking probabilities. Our framework allows us to make novel predictions about when and why people adhere to class inclusion. Evidence obtained in several studies supports these predictions and demonstrates that the proposed ranking algorithms can account for about three-quarters of participants' inferences in the Linda problem.

According to a common objection to epistemological naturalism, no empirical, scientific theory of knowledge can be normative in the way epistemological theories need to be. In response, such naturalists as W.V. Quine have claimed naturalized epistemology can be normative by emulating engineering disciplines and addressing the relations of causal efficacy between our cognitive means and ends. This paper evaluates that "engineering reply" and finds it a mixed success. Based on consideration of what it might mean to call a theory "normative," (...) seven versions of the normativity objection to epistemological naturalism are formulated. The engineering reply alone is sufficient to answer only the four least sophisticated versions. To answer the others, naturalists must draw on more resources than their engineering reply alone provides. (shrink)

The chapter presents a brief case study, in which we can observe the impact of Pierre Hadot's ideas on Martin O’Hagan, a person not far removed from us in terms of space, time, and aspirations. Hadot's concept of “Philosophy as a Way of Life (PWL)” could provide an option for a person who, excluded from and/or disillusioned by Academic philosophy, still felt the need to search for answers to a few centrally important questions that had direct impact on his life. (...) Even the characteristic that has returned like a Leitmotif throughout this chapter — analytic philosophy's tendency to ignore the so‐called Big Questions, such as that of the meaning of life — can be illuminated by means of Kuhn's theories. The author hopes that the interest in Hadot's concept of PWL will contribute to the rehabilitation of philosophy as it was before its takeover by Academic philosophy. (shrink)

This paper considers Salman Rushdie’s location as a migrant writer of the postcolonial generation while looking at criticism on his writing style by foregrounding ways in which Rushdie writes about history, reality and identity in Midnight’s Children. Underlying Rushdie’s deconstructive playfulness is a radical political spirit envisioning a humanism beyond the rigid constructions of a self/other duality, Hindu/Muslim identity, or Eastern/Western dichotomy. Furthermore, Rushdie opens up a discourse on being and belonging as a legitimate place/space for those stranded in that (...) “strange middle ground, trapped between belief and disbelief.” According to Rushdie, this space, this middle ground, which he terms the “third principle,” could be tapped to decolonize place as well as minds. The paper also analyzes how Rushdie uses the metaphors of the “whole” and “hole” in Midnight’s Children to show he writes the story of the colonial, national and postcolonial condition from the place of the personal, where personal body politics meets the geographic body politics of a whole Indian sub-continent.

Given a choice between two sealed envelopes, one of which contains twice as much money as the other (and in any case some), you don't know which contains the larger sum and so choose one at random. You are then given the option of taking the other envelope instead. Is it rational to do so? Surely not. but a specious line of reasoning suggests otherwise.
