This groundbreaking handbook of character strengths and virtues is the first progress report from a prestigious group of researchers who have undertaken the systematic classification and measurement of widely valued positive traits. Character Strengths and Virtues classifies twenty-four specific strengths under six broad virtues that consistently emerge across history and culture. This book demands the attention of anyone interested in psychology and what it can teach about the good life.

This up-to-date introduction to decision theory offers comprehensive and accessible discussions of decision-making under ignorance and risk, the foundations of utility theory, the debate over subjective and objective probability, Bayesianism, causal decision theory, game theory, and social choice theory. No mathematical skills are assumed, and all concepts and results are explained in non-technical and intuitive as well as more formal ways. There are over 100 exercises with solutions, and a glossary of key terms and concepts. An emphasis on foundational aspects (...) of normative decision theory (rather than descriptive decision theory) makes the book particularly useful for philosophy students, but it will appeal to readers in a range of disciplines including economics, psychology, political science and computer science. • Has over 100 end of chapter review questions and exercises with solutions • Includes a chapter on how to draw a decision matrix • Explains the link between individual decision making, game theory and social choice theory Contents Preface; 1.

Consequentialism, one of the major theories of normative ethics, maintains that the moral rightness of an act is determined solely by the act's consequences and its alternatives. The traditional form of consequentialism is one-dimensional, in that the rightness of an act is a function of a single moral aspect, such as the sum total of wellbeing it produces. In this book Martin Peterson introduces a new type of consequentialist theory: multidimensional consequentialism. According to this theory, an act's moral rightness depends (...) on several separate dimensions, including individual wellbeing, equality and risk. Peterson's novel approach shows that moral views about equality and risk that were previously thought to be mutually incompatible can be rendered compatible, and his precise theoretical discussion helps the reader to understand better the distinction between consequentialist and non-consequentialist theories. His book will interest a wide range of readers in ethics. (shrink)

In this paper, we examine the case of psychedelic medicine for Alzheimer’s disease and related dementias (AD/ADRD). These “mind-altering” drugs are not currently offered as treatments to persons with AD/ADRD, though there is growing interest in their use to treat underlying causes and associated psychiatric symptoms. We present a research agenda for examining the ethics of psychedelic medicine and research involving persons living with AD/ADRD, and offer preliminary analyses of six ethical issues: the impact of psychedelics on autonomy and consent; (...) the impact of “ego dissolution” on persons experiencing a pathology of self; how psychedelics might impact caregiving; the potential exploitation of patient desperation; institutional review boards’ orientation to psychedelic research; and methods to mitigate inequity. These ethical issues are magnified for AD/ADRD but bear broader relevance to psychedelic medicine and research in other clinical populations. (shrink)

Although some attention has been devoted to assessing the attitudes and concerns of businesspeople toward ethics, relatively little attention has focused on the attitudes and concerns of tomorrow's business leaders, today's college students. In this investigation a national sample was utilized to study college students' attitudes toward business ethics, with the results being analyzed by academic classification, academic major, and sex. Results of the investigation indicate that college students are currently somewhat concerned about business ethics in general, and that female (...) students in particular are more concerned about ethical issues than are their male counterparts.

This paper critically engages ethical issues in the allocation of novel, and potentially costly, health care resources to patients with disorders of consciousness. First, we review potential benefits of novel health care resources for patients and their families and outline preliminary considerations to address concerns about cost. We then address two problems regarding the allocation of health care resources to patients with disorders of consciousness: (1) the problem of uncertain moral status; and (2) the problem of accurately measuring the welfare (...) burdens these resources would relieve. We conclude by suggesting that opportunity-based frameworks might complement standard approaches for justifying resources allocation to patients with disorders of consciousness. (shrink)

The results of a survey of business professionals verified a relationship between perceptions of corporate citizenship and organizational commitment. More important, the results demonstrated that the relationship between corporate citizenship and organizational commitment was stronger among employees who believe highly in the importance of the social responsibility of businesses. The results also indicated that the ethical measure of corporate citizenship was a stronger predictor of organization commitment than the economic, legal, and discretionary measures. Last, the results revealed that the discretionary (...) measure was more strongly associated with organizational commitment among female employees. (shrink)

In 1931 the mathematical logician Kurt Godel published a revolutionary paper that challenged certain basic assumptions underpinning mathematics and logic. A colleague of Albert Einstein, his theorem proved that mathematics was partly based on propositions not provable within the mathematical system and had radical implications that have echoed throughout many fields. A gripping combination of science and accessibility, Godel’s Proof by Nagel and Newman is for both mathematicians and the idly curious, offering those with a taste for logic and philosophy (...) the chance to satisfy their intellectual curiosity.

In this analytically oriented work, Peterson articulates and defends five moral principles for addressing ethical issues related to new and existing technologies: the cost-benefit principle, the precautionary principle, the sustainability principle, the autonomy principle, and the fairness principle.

According to the canonical formulation of the modal account of luck [e.g. Pritchard (2005)], an event is lucky just when that event occurs in the actual world but not in a wide class of the nearest possible worlds where the relevant conditions for that event are the same as in the actual world. This paper argues, with reference to a novel variety of counterexample, that it is a mistake to focus, when assessing a given event for luckiness, on events distributed (...) over just the nearest possible worlds. More specifically, our objection to the canonical formulation of the modal account of luck reveals that whether an event is lucky depends crucially on events distributed over all possible worlds–viz., across the modal universe. It is shown that an amended modal account of luck which respects this point has the additional virtue of avoiding a notable kind of counterexample to modal accounts of luck proposed by Lackey (2008).

This study examined the relationship between unethical employee behavior and the dimensions of the Ethical Climate Questionnaire (ECQ). In order to explore the relationship between the dimensions of the ECQ and unethical behavior, the factor structure of five previously identified empirical models and the hypothesized nine-dimension model for the ECQ was tested with a confirmatory factor analysis. The analysis revealed that the hypothesized nine-dimension model provided as good or even better fit to the data than the five empirically derived models. (...) Therefore, the nine-dimensional model was used to examine the criterion-related validity of the ECQ. The results demonstrated that the nine ethical climate dimensions were correlated with some of the unethical behaviors examined in this study, but not others. However, the results clearly demonstrated that most of the ethical climate dimensions were significantly related to an aggregate measure of unethical behavior. It was suggested that these results might account for the differences in previous studies on the criterion-related validity of the ECQ. The results also replicated a previous report that the association between unethical behavior and ethical climate is stronger in organizations that do not have a code of ethics. Finally, a difference was observed in the ethical climates for organizations with a code of ethics and organizations without a code of ethics. (shrink)

In Plato's Apology, Socrates says he spent his life examining and questioning people on how best to live, while avowing that he himself knows nothing important. Elsewhere, however, for example in Plato's Republic, Plato's Socrates presents radical and grandiose theses. In this book Sandra Peterson offers a hypothesis which explains the puzzle of Socrates' two contrasting manners. She argues that the apparently confident doctrinal Socrates is in fact conducting the first step of an examination: by eliciting his interlocutors' reactions, his (...) apparently doctrinal lectures reveal what his interlocutors believe is the best way to live. She tests her hypothesis by close reading of passages in the Theaetetus, Republic and Phaedo. Her provocative conclusion, that there is a single Socrates whose conception and practice of philosophy remain the same throughout the dialogues, will be of interest to a wide range of readers in ancient philosophy and classics.

Schelling's first systematic attempt to articulate a complete philosophy of nature.

Theory of Mind (ToM) is the cognitive achievement that enables us to report our propositional attitudes, to attribute such attitudes to others, and to use such postulated or observed mental states in the prediction and explanation of behavior. Most normally developing children acquire ToM between the ages of 3 and 5 years, but serious delays beyond this chronological and mental age have been observed in children with autism, as well as in those with severe sensory impairments. We examine data from (...) studies of ToM in normally developing children and those with deafness, blindness, autism and Williams syndrome, as well as data from lower primates, in a search for answers to key theoretical questions concerning the origins, nature and representation of knowledge about the mind. In answer to these, we offer a framework according to which ToM is jointly dependent upon language and social experience, and is produced by a conjunction of language acquisition with children's growing social understanding, acquired through conversation and interaction with others. We argue that adequate language and adequate social skills are jointly causally sufficient, and individually causally necessary, for producing ToM. Thus our account supports a social developmental theory of the genesis of human cognition, inspired by the work of Sellars and Vygotsky. How are we to decide whether to take reason to be an essentially private thing that can, however, turn on a public display when it chooses to do so, or, like conversing, to be an essentially social skill, which can, however, be retained a while through periods of solitary confinement? (Annette Baier, The Commons of the Mind, p. 5). The squirrel does not infer by induction that it is going to need stores next winter as well (Wittgenstein, On Certainty§ 287). The problem of thought and language thus extends beyond the limits of natural science and becomes the focal problem of historical human psychology, i.e. of social psychology. Consequently, it must be posed in a different way (Vygotsky, Thought and Language, p. 51). From the very first days of the child's development his activities acquire a meaning of their own in a system of social behaviour and, being directed towards a definite purpose, are refracted through the prism of the child's environment. The path from object to child and from child to object passes through another person. This complex human structure is the product of a developmental process deeply rooted in the links between individual and social history (Vygotsky, Mind in Society, p. 30). (shrink)

This article argues that supported decision making is ideal for people with dynamic cognitive and functional impairments that place them at the margins of autonomy. First, we argue that guardianship and similar surrogate decision-making frameworks may be inappropriate for people with dynamic impairments. Second, we provide a conceptual foundation for supported decision making for individuals with dynamic impairments, which integrates the social model of disability with relational accounts of autonomy. Third, we propose a three-step model that specifies the necessary conditions (...) of supported decision making: identifying domains for support; identifying kinds of supports; and reaching a mutually acceptable and formal agreement. Finally, we identify a series of challenges for supported decision making, provide preliminary responses, and highlight avenues for future bioethics research. (shrink)

Physically frail, badly educated girls, brought up to lead useless lives as idle gentlewomen, married to dominant husbands, and relegated to "separate spheres" of life—these phrases have often been used to describe Victorian upper-middle-class women. M. Jeanne Peterson rejects such formulations and the received wisdom they embody in favor of a careful examination of Victorian ladies and their lives. Focusing on a network of urban professional families over three generations, this book examines the scope and quality of gentlewomen's education, their (...) physical lives, their relationship to money, their experience of family illness and death, and their relationships to men (brothers and friends as well as fathers and husbands). Peterson also examines the prominent place of work in the lives of these "leisured" Victorian ladies, both single and married. Far from idle, the mothers, wives, and daughters of Victorian clergymen, doctors, lawyers, university dons, and others were accomplished and productive members of society who made substantial public and private contributions to virtually every sphere of Victorian life.

Pure time preference is a preference for something to come at one point in time rather than another merely because of when it occurs in time. In opposition to Sidgwick, Ramsey, Rawls, and Parfit we argue that it is not always irrational to be guided by pure time preferences. We argue that even if the mere difference of location in time is not a rational ground for a preference, time may nevertheless be a normatively neutral ground for a preference, and (...) this makes it plausible to claim that the preference is rationally permitted.

Armchair philosophers have questioned the significance of recent work in experimental philosophy by pointing out that experiments have been conducted on laypeople and undergraduate students. To challenge a practice that relies on expert intuitions, so the armchair objection goes, one needs to demonstrate that expert intuitions rather than those of ordinary people are sensitive to contingent facts such as cultural, linguistic, socio-economic, or educational background. This article does exactly that. Based on two empirical studies on populations of 573 and 203 (...) trained philosophers, respectively, it demonstrates that expert intuitions vary dramatically according to at least one contingent factor, namely, the linguistic background of the expert: philosophers make different intuitive judgments if their native language is English rather than Dutch, German, or Swedish. These findings cast doubt on the common armchair assumption that philosophical theories based on armchair intuitions are valid beyond the linguistic background against which they were developed.

Following neo-Aristotelians Alasdair MacIntyre and Martha Nussbaum, we claim that humans are story-telling animals who learn from the stories of diverse others. Moral agents use rational emotions, such as compassion which is our focus here, to imaginatively reconstruct others’ thoughts, feelings and goals. In turn, this imaginative reconstruction plays a crucial role in deliberating and discerning how to act. A body of literature has developed in support of the role narrative artworks (i.e. novels and films) can play in allowing us (...) the opportunity to engage imaginatively and sympathetically with diverse characters and scenarios in a safe protected space that is created by the fictional world. By practising what Nussbaum calls a ‘loving attitude’, her version of ethical attention, we can form virtuous habits that lead to phronesis (practical wisdom). In this paper, and taking compassion as an illustrative focus, we examine the ways that students’ moral education might usefully develop from engaging with narrative artworks through Philosophy for Children (P4C), where philosophy is a praxis, conducted in a classroom setting using a Community of Inquiry (CoI). We argue that narrative artworks provide useful stimulus material to engage students, generate student questions, and motivate philosophical dialogue and the formation of good habits which, in turn, supports the argument for philosophy to be taught in schools.

In this article, we defend two claims about the precautionary principle. The first is that there is no ‘core’ precautionary principle that unifies all its different versions. It is more plausible to think of the different versions as being related to each other by way of family resemblances. So although precautionary principle x may have much in common with precautionary principle y, and y with z, there is no set of necessary and sufficient conditions that unify all versions of the (...) principle. Our second claim is that it is sometimes appropriate to think of the precautionary principle as a midlevel principle in the sense proposed by Beauchamp and Childress in their Principles of Biomedical Ethics, i.e. as a non-rigid moral principle. We argue that if the precautionary principle is conceived as a non-rigid principle that needs to be balanced against other principles before a moral verdict can be reached, then this enables us to address some standard objections to the principle.

Based on a modern reading of Aristotle’s theory of friendship, we argue that virtual friendship does not qualify as genuine friendship. By ‘virtual friendship’ we mean the type of friendship that exists on the internet, and seldom or never is combined with real life interaction. A ‘traditional friendship’ is, in contrast, the type of friendship that involves substantial real life interaction, and we claim that only this type can merit the label ‘genuine friendship’ and thus qualify as morally valuable. The (...) upshot of our discussion is that virtual friendship is what Aristotle might have described as a lower and less valuable form of social exchange. (shrink)

An essential all-in-one introduction, Ethics for Engineers provides in-depth coverage of major ethical theories, professional codes of ethics, and case studies in a single volume. Incorporating numerous practical examples and about 100 review questions, it helps students better understand and address ethical issues that they may face in their future careers. Topics covered include whistle-blowing, the problem of many hands, gifts, bribes, conflicts of interest, engineering and environmental ethics, privacy and computer ethics, ethical technology assessment, and the ethics of cost-benefit (...) analysis and risk and uncertainty.

What is the status of belief in God? Must a rational case be made or can such belief be properly basic? Is it possible to reconcile the concept of a good God with evil and suffering? In light of great differences among religions, can only one religion be true? The most comprehensive work of its kind, Reason and Religious Belief, now in its fourth edition, explores these and other perennial questions in the philosophy of religion. Drawing from the best in (...) both classical and contemporary discussions, the authors examine religious experience, faith and reason, the divine attributes, arguments for and against the existence of God, divine action (in various forms of theism), Reformed epistemology, religious language, religious diversity, religion and science, and much more. Retaining the engaging style and thorough coverage of previous editions, the fifth edition features revised treatments of omnipotence, miracles, and providence and updated suggestions for further reading. A sophisticated yet accessible introduction, Reason and Religious Belief, Third Edition, is ideally suited for use with the authors' companion anthology, Philosophy of Religion: Selected Readings, Fifth Edition (OUP, 2015).

We argue that some algorithms are value-laden, and that two or more persons who accept different value-judgments may have a rational reason to design such algorithms differently. We exemplify our claim by discussing a set of algorithms used in medical image analysis: In these algorithms it is often necessary to set certain thresholds for whether e.g. a cell should count as diseased or not, and the chosen threshold will partly depend on the software designer’s preference between avoiding false positives and (...) false negatives. This preference ultimately depends on a number of value-judgments. In the last section of the paper we discuss some general principles for dealing with ethical issues in algorithm-design. (shrink)

Joseph Heath defends competitive markets and conceptualizes business ethics with reference to Pareto efficiency, which he takes to be the “implicit morality of the market.” His justification for markets is that they generate Pareto efficient outcomes, meaning that markets optimally satisfy consumer preferences. And, for Heath, business ethics is the set of normative constraints—regulation and beyond-compliance norms—needed to preserve that outcome. The present paper accepts Heath’s claim that the economic justification for markets is ethical, in that satisfying consumer preferences is (...) a good. But, contra Heath, the ethical consideration at work is a consequentialist one; and acknowledging this consequentialism exposes limitations of Heath’s “market failures” approach to business ethics. We suggest two limitations, and we expect many will accept our argument that Heath’s conception of business ethics is too narrow. The present paper outlines two broader implications. First, acknowledging that the justification for markets is ethical eliminates the apparent—and false—conflict between purportedly amoral economic activity on one hand and ethical considerations on the other; instead, business ethics is a matter of weighing the consequentialist ethical benefit of economic activity and markets against other moral arguments/other ethical considerations. Second, Heath restricts business ethics to the constraints needed to protect the market’s ability to efficiently satisfy consumer preferences, constraints he calls “efficiency imperatives”; this restriction supports the widespread tendency to think that all social problems are economic; and, a business ethics so-conceived diminishes the perceived importance of noneconomic values—this attitude is dangerous.

This paper summarizes the results of 11 separate studies of deaf children’s performance on standard tests of false belief understanding, the results of which combine to show that deaf children from hearing families are likely to be delayed in acquiring a theory of mind. Indeed, these children generally perform no better than autistic individuals of similar mental age. Conversational and neurological explanations for deficits in mental state understanding are considered in relation to recent evidence from studies of deaf, autistic, and (...) normally developing children with varied levels of access to talk about mental states at home with family members during the preschool years.

This article provides an ethical analysis of the U.S. practice guideline update on disorders of consciousness. Our analysis focuses on the guideline’s recommendations regarding the use of investigational neuroimaging methods to assess brain‐injured patients. Complex and multifaceted ethical issues have emerged because these methods alter the clinical understanding of consciousness. We address issues of false hope, patient suffering, and cost. We argue that, in spite of these concerns, there is significant benefit to using neuroimaging to assess brain‐injured patients in most (...) cases. (shrink)

Decades of psychological research have been aimed at modeling how people learn features and categories. The empirical validation of these theories is often based on artificial stimuli with simple representations. Recently, deep neural networks have reached or surpassed human accuracy on tasks such as identifying objects in natural images. These networks learn representations of real‐world stimuli that can potentially be leveraged to capture psychological representations. We find that state‐of‐the‐art object classification networks provide surprisingly accurate predictions of human similarity judgments for (...) natural images, but they fail to capture some of the structure represented by people. We show that a simple transformation that corrects these discrepancies can be obtained through convex optimization. We use the resulting representations to predict the difficulty of learning novel categories of natural images. Our results extend the scope of psychological experiments and computational modeling by enabling tractable use of large natural stimulus sets. (shrink)

Cross-national studies of business-related ethicality frequently have concluded that Americans possess higher ethical standards than non-Americans. These conclusions have generally been based on survey responses of relatively small convenience samples of individuals in a very limited number of countries. This article reports a study of the relationship between nationality and business-related ethicality based on survey responses from more than 6300 business students attending 120 colleges and universities in 36 countries. Two well-documented determinants of business ethics (gender and religiosity) were investigated (...) as moderators of the nationality–business ethicality relationship. The major research finding is that, while statistically significant differences were found between the business-related ethicality of American survey participants and the business-related ethicality of the non-American survey participants, the magnitudes of the differences were not substantial. The results of the study suggest that (i) more empirical cross-cultural/national research is required on business-related ethicality and (ii) previous explanations for cross-cultural/national differences in ethics need to be reconsidered before further generalizations are warranted.

Readers of fiction tend to have better abilities of empathy and theory of mind. We present a study designed to replicate this finding, rule out one possible explanation, and extend the assessment of social outcomes. In order to rule out the role of personality, we first identified Openness as the most consistent correlate. This trait was then statistically controlled for, along with two other important individual differences: the tendency to be drawn into stories and gender. Even after accounting for these (...) variables, fiction exposure still predicted performance on an empathy task. Extending these results, we also found that exposure to fiction was positively correlated with social support. Exposure to nonfiction, in contrast, was associated with loneliness, and negatively related to social support. (shrink)

A multiphase study tested a proposed mediated moderation model for the joint effects of ethical pressure and power distance orientation on accountants’ ethical judgments of earnings management. Results based on a sample of 354 accountants from China indicated that the relationship between ethical pressure and ethical judgments of earnings management is contingent on the accountants’ power distance orientation. That is, the relationship between ethical pressure and ethical judgments of earnings management was stronger for accountants with a high power distance orientation. (...) The results also demonstrated that ethical beliefs in support of the company serve as a mediator for the interaction effect of ethical pressure and power distance orientation on the outcome. These results are discussed in terms of viewing earnings management as a form of unethical pro-organizational behavior which can be effectively investigated within the framework of the person-situation interactionist model.

We argue that non-epistemic values, including moral ones, play an important role in the construction and choice of models in science and engineering. Our main claim is that non-epistemic values are not only “secondary values” that become important just in case epistemic values leave some issues open. Our point is, on the contrary, that non-epistemic values are as important as epistemic ones when engineers seek to develop the best model of a process or problem. The upshot is that models are (...) neither value-free, nor depend exclusively on epistemic values or use non-epistemic values as tie-breakers. (shrink)

This study examines the presence and roles of female directors of U.S. Fortune 500 firms, focusing on committee assignments and director background. Prior work from almost two decades ago concludes that there is a systematic bias against females in assignment to top board committees. Examining a recent data set with a logistic regression model that controls for director and firm characteristics, director resource-dependence roles and interaction between director gender and director characteristics, we find that female directors are less likely than (...) male directors to sit on executive committees and more likely than male directors to sit on public affairs committees. There is little if any evidence of systematic gender bias in director assignment to other board committees. We find some evidence that boards evaluate resource dependence differently for women than men. (shrink)

In this paper we discuss the hypothesis that, ‘moral agency is distributed over both humans and technological artefacts’, recently proposed by Peter-Paul Verbeek. We present some arguments for thinking that Verbeek is mistaken. We argue that artefacts such as bridges, word processors, or bombs can never be (part of) moral agents. After having discussed some possible responses, as well as a moderate view proposed by Illies and Meijers, we conclude that technological artefacts are neutral tools that are at most bearers (...) of instrumental value.

This paper presents a novel learning model Clarion , which is a hybrid model based on the two-level approach proposed in Sun (1995). The model integrates neural, reinforcement, and symbolic learning methods to perform on-line, bottom-up learning (i.e., learning that goes from neural to symbolic representations). The model utilizes both procedural and declarative knowledge (in neural and symbolic representations respectively), tapping into the synergy of the two types of processes. It was applied to deal with sequential decision tasks. Experiments and (...) analyses in various ways are reported that shed light on the advantages of the model. (shrink)
