Every year in this country, some 10,000 college and university courses are taught in applied ethics. And many professional organizations now have their own codes of ethics. Yet social science has had little impact upon applied ethics. This book promises to change that trend by illustrating how social science can make a contribution to applied ethics. The text reports psychological studies relevant to applied ethics for many professionals, including accountants, college students and teachers, counselors, dentists, doctors, journalists, nurses, school teachers, (...) athletes, and veterinarians. Each chapter begins with the research base of the cognitive-developmental approach--especially linked to Kohlberg and Rest's Defining Issues Test. Finally, the book summarizes recent research on the following issues: * moral judgment scores within and between professions, * pre- and post-test evaluations of ethics education programs, * moral judgment and moral behavior, * models of professional ethicseducation, and * models for developing new assessment tools. Researchers in different professional fields investigate different questions, develop different research strategies, and report different findings. Typically researchers of one professional field are not aware of research in other fields. An important aim of the present book is to bring this diverse research together so that cross-fertilization can occur and ideas from one field can transfer to another. (shrink)

We report the results of two studies that examine folk metaethical judgments about the objectivity of morality. We found that participants attributed almost as much objectivity to ethical statements as they did to statements of physical fact and significantly more objectivity to ethical statements than to statements about preferences or tastes. In both studies, younger participants attributed less objectivity to ethical statements than older participants. Females were observed to attribute slightly less objectivity to ethical statements than males, and we found (...) important interactions between attributions of objectivity and other factors, such as how strong participants’ moral opinions were and how much disagreement about the issue they perceived to exist within society. We believe our results have significant implications for debates about the nature of folk morality and about the nature of morality in general. (shrink)

Philosophy and Phenomenological Research, EarlyView.

In 2004 Edouard Machery, Ron Mallon, Shaun Nichols and Stephen Stich published what has become one of the most widely discussed papers in experimental philosophy, in which they reported that East Asian and Western participants had different intuitions about the semantic reference of proper names. A flurry of criticisms of their work has emerged, and although various replications have been performed, many critics remain unconvinced. We review the current debate over Machery et al.’s (2004) results and take note of which (...) objections to their work have been satisfactorily answered and which ones still need to be addressed. We then report the results of studies that reveal significant cross-cultural and intra-cultural differences in semantic intuitions when we control for variables that critics allege have had a potentially distorting effect on Machery et al.’s findings. These variables include the epistemic perspective from which participants are supposed to understand the research materials, unintended anchoring effects of those materials, and pragmatic factors involved in the interpretation of speech acts within them. Our results confirm the robustness of the cross-cultural differences observed by Machery et al. and thereby strengthen the philosophical challenge they pose. (shrink)

The results of four experiments provide evidence for controlled processing in the absence of awareness. Participants identified the colour of a neutral distracter word. Each of four words was presented in one of the four colours 75% of the time or 50% of the time . Colour identification was faster when the words appeared in the colour they were most often presented in relative to when they appeared in another colour, even for participants who were subjectively unaware of any contingencies (...) between the words and the colours. An analysis of sequence effects showed that participants who were unaware of the relation between distracter words and colours nonetheless controlled the impact of the word on performance depending on the nature of the previous trial. A block analysis of contingency-unaware participants revealed that contingencies were learned rapidly in the first block of trials. Experiment 3 showed that the contingency effect does not depend on the level of awareness, thus ruling out explicit strategy accounts. Finally, Experiment 4 showed that the contingency effect results from behavioural control and not from semantic association or stimulus familiarity. These results thus provide evidence for implicit control. (shrink)

Adam Smith wrote two books, one about economics and the other about morality. How do these books go together? How do markets and morality mix? James Otteson provides a comprehensive examination and interpretation of Smith's moral theory and demonstrates how his conception of morality applies to his understanding of markets, language and other social institutions. Considering Smith's notions of natural sympathy, the impartial spectator, human nature and human conscience, the author addresses whether Smith thinks that moral judgments enjoy a (...) transcendent sanction.

This paper reports the results of a four year study to measure the effect of a Business and Society course on the ethical judgment of students. The research involves a matched pre/post survey with control design, with the Business and Society course functioning as the treatment variable. The subjects were undergraduate and graduate (M.B.A.) business students (n=460). The answer to the question posed by the title of this paper is yes, in a more ethical direction.

Knobe (2003a, 2003b, 2004b) and others have demonstrated the surprising fact that the valence of a side-effect action can affect intuitions about whether that action was performed intentionally. Here we report the results of an experiment that extends these findings by testing for an analogous effect regarding knowledge attributions. Our results suggest that subjects are less likely to find that an agent knows an action will bring about a side-effect when the effect is good than when it is bad. It (...) is further argued that these findings, while preliminary, have important implications for recent debates within epistemology about the relationship between knowledge and action. (shrink)

We report the results of a study that investigated the views of researchers working in seven scientific disciplines and in history and philosophy of science in regard to four hypothesized dimensions of scientific realism. Among other things, we found that natural scientists tended to express more strongly realist views than social scientists, that history and philosophy of science scholars tended to express more antirealist views than natural scientists, that van Fraassen’s characterization of scientific realism failed to cluster with more standard (...) characterizations, and that those who endorsed the pessimistic induction were no more or less likely to endorse antirealism.

Scientists use a variety of modes of representation in their work, but philosophers have studied mainly sentences expressing propositions. I ask whether diagrams are mere conveniences in expressing propositions or whether they are a distinct, ineliminable mode of representation in scientific texts. The case of path analysis, a statistical method for quantitatively assessing the relative degree of causal determination of variation as expressed in a causal path diagram, is discussed. Path analysis presents a worst case for arguments against eliminability since (...) path diagrams are usually presumed to be mathematically or logically “equivalent” in an important sense to sets of linear path equations. I argue that path diagrams are strongly generative, i.e., that they add analytical power to path analysis beyond what is supplied by linear equations, and therefore that they are ineliminable in a strong scientific sense.

Propositions alone are not constitutive of science. But is the "non-propositional" side of science theoretically superfluous: must philosophy of science consider it in order to adequately account for science? I explore the boundary between the propositional and non-propositional sides of biological theory, drawing on three cases: Grinnell's remnant models of faunas, Wright's path analysis, and Weismannism's role in the generalization of evolutionary theory. I propose a picture of material model-building in biology in which manipulated systems of material objects function as (...) theoretical models. In each of the cases, material systems such as diagrams play important generative as well as presentational roles. (shrink)

The goal of this book is to develop a new approach to reading the rule-following sections guided by a simple idea. The simple idea is that Wittgenstein's remarks on rule-following are split between two distinct but complementary projects. The projects are marked not only by different guiding questions, but different presuppositions and methodologies. There is of course precedent for reading the rule-following remarks as comprising two parts. For example, there is the reading of (S. Kripke 1982) on which Wittgenstein first (...) presents a skeptical challenge before turning to its skeptical solution. And there are readings like (Minar 2011) and (Goldfarb 2012) that likewise treat the sections as roughly divided into two components or "chapters." But even these commentators do not explicitly associate their components with different questions and associated methodologies, and so fall short of attributing to Wittgenstein's text anything quite like the thoroughgoing bipartite structure I will be proposing here.

Having asked, “What, then, is time?” Augustine admitted, “I know well enough what it is, provided that nobody asks me; but if I am asked what it is and try to explain, I am baffled.” We all have a sense of time, but the description and explanation of it remain remarkably elusive. Through a series of detailed descriptions, Husserl attempted to clarify this sense of time. In my book, I trace the development of his account of our temporal self-awareness, starting (...) with his early 1905-1909 lectures on time consciousness and proceeding through the 1917-18 Bernau Manuscripts, the Analyses of Passive Syntheses of the 1920’s and ending with the C, B and E manuscripts on time and instincts of the 1930s. Although my book covers all the stages of Husserl’s account of temporality, it is nonetheless systematic in its approach. It is organized about a number of basic topics in the theory of time and presents and critically appraises Husserl’s positions on the issues pertaining to each. • THE ONTOLOGICAL STATUS OF TIME: Is time objective or subjective? Is it “out there,” a part of external reality or does it have a merely subjective existence, residing only in our memories and anticipations? Does Husserl’s “subjective” account presuppose ob-jective time? • THE “PRESENCE” OF THE PAST AS PAST: Memory, if it is to be distinguished from a direct, sensuous perception, must grasp the past as past. It must somehow “see” what no longer exists as no longer existing. The issue is: how do we do this? The same question arises with regard to our grasp through anticipation of the future as future. • THE TEMPORALITY OF OBJECTS: For Husserl, the apprehension of any sort of extended event, such as a melody, involves the synthesis of the “retentions” (the short term memories) of its notes and the anticipations these retentions awake in us. The question, here, is: what exactly is involved in this synthesis of retentions and anticipa-tions? How can these elements come together to present a single, individual object rather than presenting us with merely a collection of disparate presentations? In other words: How does temporal synthesis accomplish this presentation? • THE TEMPORALITY OF CONSCIOUSNESS: Husserl asserts that consciousness, in placing its object in time also places itself in time. How does it do this? What is the relation between the consciousness that places itself in time and the consciousness that is placed in time? How do we unify them? • THE ONTOLOGICAL STATUS OF TIME-CONSTITUTING PHENOMENA: Husserl claims that “time-constituting phenomena are evidently objectivities fundamentally different than those constituted in time. They are neither individual objects nor individual processes, and the predicates of such objects or processes cannot be meaningfully ascribed to them.” This assertion raises a number of questions about the ontological status of these time-constituting phenomena. If we cannot apply the predicates of individual objects to them, what is the nature of their being? Given that such phenomena com-pose the field of consciousness, what is the ontological status of consciousness? Furthermore, if our apprehension directs itself towards individual objects, how can our consciousness grasp the pre-individual, time-constituting phenomena that make it up? At issue here is the status of Husserl’s own descriptions of consciousness and the temporal process. Does his theory undermine the possibility of the evidence he presents for it? • THE RELATION OF CONSCIOUSNESS TO THE EGO: Our sense of self involves more than our consciousness, more than the memories, perceptions, and anticipations that give it its content. It involves our sense as the subjective referent of every act, as the person to whom the world appears, as the one who is affected by the world and who acts with regard to it. What is the relation of this sense of self to our time consciousness? How does the simultaneous constitution of consciousness and its object result in the presence of the I that is the subject of consciousness? (shrink)

Thought experiments have a long and illustrious history. But in spite of their acknowledged importance, there has until recently been remarkably little said about them. How do they work? Why do they work? What are the different ways in which they work? And above all: How is it possible that just by thinking we can learn something new about the world? This paper surveys some of the recent approaches, including my own , and discusses their various prospects. Chief among the (...) alternatives is John Norton′s “argument” view. The paper ends by drawing attention to some of the outstanding problems in thought experiments. These are some of the issues that will likely be the focus of attention and research in the future.

The Sleeping Beauty puzzle has dramatized the divisive question of how de se beliefs should be integrated into formal theories of rational belief change. In this paper, I look ahead to a related question: how should de se beliefs be integrated into formal theories of rational choice? I argue that standard decision theoretic frameworks fail in special cases of de se uncertainty, like Sleeping Beauty. The nature of the failure reveals that sometimes rational choices are determined independently of one’s credences (...) in the kinds of ‘narrow’ de se propositions that Sleepy Beauty has set in relief. Consequently, in addition to pinpointing a failure of standard decision theoretic frameworks, this result casts doubt on a large class of strategies for determining principles for the rationally updating de se beliefs in cases like Sleeping Beauty, and also calls into question the importance of making such a determination at all.

Internationally, governments, health and exercise practitioners are struggling with the threat posed by physical inactivity leading to worsening outcomes in health and life expectancy and the associated high economic costs. To meet this challenge it is important to enhance the quality, and quantity, of participation in sports and physical activity throughout the life course to sustain healthy and active lifestyles. This paper supports the need to develop a physically literate population, who meaningfully engage in play and physical activity through the (...) development of functional movement skills in enriched environments. This is a shift away from reductionist approaches to physical activity engagement and maintenance to an ecological dynamics approach that focuses on enrichment to support functional movement skill learning and development. This is an embedded approach to physical literacy that allows learners the space and time to “explore–discover” within environments that will lead to a concomitant self-organization of highly intricate network of co-dependent sub-systems resulting in functional movement solutions for the performance task and enduring positive adaptations to subsystems supporting the physical literacy journey across the life course. “Explore-discover adapt” is at the heart of two contemporary learner-centered pedagogies: Non-linear Pedagogy and the Athletic Skills Model. Both emphasize the importance of enrichment experiences from an early age, and throughout life course, and both appreciate the inherent complexity involved in the learning process and the importance of designing a rich and varied range of athletic, participatory experiences that will support the embedded development of physical literacy leading to ongoing physical activity for all. The final part of this paper will demonstrate the potential of an ecological dynamics approach for supporting the concept of physical literacy by providing a roadmap for a reliable and valid measurement of physical literacy when considered from both an ecological dynamics perspective and the phenomenology understanding of physical literacy.

This study examines the ethical values of respondents by level in the organizational hierarchy of a single firm. It also explores the possible impacts of gender, education and years of experience on respondents' values as well as their perceptions of how the organization and professional associations influence their personal values. Results showed that, although there were differences in individuals' ethical values by hierarchical level, significantly more differences were observed by the length of tenure with the organization. While respondents, as a (...) whole, were rather ambivalent in their perception of the organization's and professional associations' influence on their values, sales/service persons frequently felt pressured to modify their values in order to achieve company goals.

This paper compares the ethical decisions and attitudes of business students and practitioners. Recent unpublished data from a national study of over 1600 students are contrasted with information reported previously. Students are found consistently to make less ethical choices than practitioners, and there is some indication that students are making less ethical choices in the 1980s than in the 1960s. In addition, both students and practitioners agree that buyers should beware, view the role of business more narrowly, and find fewer (...) incentives to behave ethically over time. Codes of ethics appear to be less influential than the individual's strong personal value system and one's superiors behaving ethically; support for codes is declining. The paper concludes with observations about the limitations and possibilities for survey research in this area drawing on other studies that used the same instrument utilized for this paper. Some implications for future research are suggested. (shrink)

Blackmail raises a pair of parallel legal and moral problems, sometimes referred to as the "paradox of blackmail". It is sometimes legal and morally permissible to ask someone for money, or to threaten to release harmful information about them, while it is illegal and morally impermissible to do these actions jointly. I address the moral version of this paradox by bringing instances of blackmail under a general account of wrongful coercion. According to this account, and contrary to the appearances which (...) give rise to the paradox, threatening the release of harmful information to constrain another's actions is almost never morally impermissible unless it is likewise impermissible to carry out one's threat. To defend this claim I identify a special wrong that arises in the paradoxical cases of threatened information release. The account also resolves a number of other puzzles about blackmail—for example, why profiting from a threat in blackmail can sometimes be impermissible, even though accepting identical payment from an independent offer to retain the same information can be permissible.

Dimensions of character are often overlooked in professional practice at the expense of the development of technical competence and operational efficiency. Drawing on philosophical accounts of virtue ethics and positive psychology, the present work attempts to elevate the role of ‘good’ character in the professional domain. A ‘good’ professional is ideally one that exemplifies dimensions of character informed by sound judgement. A total of 2340 professionals, from five discrete professions, were profiled based on their valuation of qualities pertaining to character (...) and judgement. Profile differences were subsequently examined in the self-reported experience of professional purpose towards a wider societal ‘good’. Analysis of covariance, controlling for stage of career, revealed that professionals valuing character reported higher professional purpose than those overweighting the importance of judgement or valuing neither character nor judgement, F = 7.92, p <.001. No differences were found between the two groups valuing character, irrespective of whether judgement was valued simultaneously. This profiling analysis of entry-level and in-service professionals, based on their holistic character composition, paves the way for fresh philosophical discussion regarding what constitutes a ‘good’ professional and the interplay between character and judgement. The empirical findings may be of substantive value in helping to recognise how the dimensions of character and judgement may impact upon practitioners’ professional purpose. (shrink)

Abductivists claim that explanatory considerations (e.g., simplicity, parsimony, explanatory breadth, etc.) favor belief in the external world over skeptical hypotheses involving evil demons and brains in vats. After showing how most versions of abductivism succumb fairly easily to obvious and fatal objections, I explain how rationalist versions of abductivism can avoid these difficulties. I then discuss the most pressing challenges facing abductivist appeals to the a priori and offer suggestions on how to overcome them.

De se exceptionalism is the view, notably championed by Perry (1979) and Lewis (1979), that our characteristically 'first-personal' ways of thinking about ourselves present unique challenges to standard views of propositional attitudes like belief. Though the view has won many adherents, it has recently come under a barrage of deserved criticism. A key claim of detractors is that classic examples used to motivate de se exceptionalism from de se ignorance or misidentification are nothing more than familiar Frege-puzzles, which raise no (...) issues exclusive to self-directed thought. After reviewing how this simple objection has substantial force against the classic defenses of exceptionalism, I provide new arguments based on cases of pure de se ignorance that avoid the criticism. Afterward, I revisit Lewis's defense of exceptionalism, diagnosing how he arrived at roughly the right conclusions on the basis of an argument that begged critical questions and obscured the representationally unique features of the de se.

We develop an account of laboratory models, which have been central to the group selection controversy. We compare arguments for group selection in nature with Darwin's arguments for natural selection to argue that laboratory models provide important grounds for causal claims about selection. Biologists get information about causes and cause-effect relationships in the laboratory because of the special role their own causal agency plays there. They can also get information about patterns of effects and antecedent conditions in nature. But to (...) argue that some cause is actually responsible in nature, they require an inference from knowledge of causes in the laboratory context and of effects in the natural context. This process, cause detection, forms the core of an analogical argument for group selection. We discuss the differing roles of mathematical and laboratory models in constructing selective explanations at the group level and apply our discussion to the units of selection controversy to distinguish between the related problems of cause determination and evaluation of evidence. Because laboratory models are at the intersection of the two problems, their study is crucial for framing a coherent theory of explanation for evolutionary biology. (shrink)

A fresh explication of the Thomist justification of self-defense casts off the hobbles of the principle of double effects to find a more secure footing in the historicaldevelopment of subjective natural rights by medieval jurists, and a straight-forward application to the latent threat of death in childbirth posed by non-consensual pregnancy. By articulating the implicit Thomistic right to defensive abortion in terms of conditional rights bestowed in Creation as correlative to particular natural law duties, justly proportionate limits to defensive abortion (...) are identified, and balanced against the forfeited or reserved natural rights variously imputed to conceptus and embryo in non-consensual pregnancies. Subsequently, the varieties of involuntary consent are examined from a Thomist perspective with a view to their relevance in justifying recourse to a rehabilitated practice of defensive abortion when free and full consent to impregnation and childbirth is absent.

John Broome argues that fairness requires that claims are satisfied in proportion to their strength. Broome holds that, when distributing indivisible goods, fairness requires the use of weighted lotteries as a surrogate to satisfy proportionally each candidate's claims. In this article, we present two arguments against Broome's account of fairness. First, we argue that it is almost impossible to calculate the weights of the lotteries in accordance with the requirements of fairness. Second, we argue that Broome rules out those methods (...) whose use might provide some resolution to this problem. From these arguments, we conclude that, contra Broome, fairness does not require the proportional satisfaction of claims. (shrink)

As documented in Part I, monogenism, the descent of all human beings from Adam and Eve, was closely linked to the Catholic doctrine of original sin throughout the first half of the twentieth century. Theological reservations about polygenism, the more scientifically supported account of human origins through a transitional population, was brought to a head by Pius XII’s 1950 encyclical Humani generis. Although the encyclical allowed discussion of human evolution, polygenism was prohibited because “It does not appear how such a (...) view can be reconciled with the doctrine of original sin.” Nevertheless, during and after Vatican II de facto theological acceptance of polygenism became commonplace even though the prohibition was not withdrawn. While some modern conceptions of original sin make a reliance upon monogenism unnecessary, another school of thought emphasizes a spiritual rather than a biological understanding of the concept. It remains to be seen whether polygenism can be unanimously accepted as a scientific phenomenon that is not theologically threatening. Reflection on the Vatican’s long period of ambivalence about the motion of the earth suggests that a similar prospect can be foreseen for polygenism even though it is subject to development in a manner that geostasis was not.

Th e present article reports a series of experiments designed to extend the empirical investigation of folk metaethical intuitions by examining how different kinds of ethical disagreement can impact attributions of objectivity to ethical claims.

A number of researchers have begun to demonstrate that the widely discussed ?Knobe effect? (wherein participants are more likely to think that actions with bad side-effects are brought about intentionally than actions with good or neutral side-effects) can be found in theory of mind judgments that do not involve the concept of intentional action. In this article we report experimental results that show that attributions of knowledge can be influenced by the kinds of (non-epistemic) concerns that drive the Knobe effect. (...) Our findings suggest there is good reason to think that the epistemic version of the Knobe effect is a theoretically significant and robust effect, and that the goodness or badness of side-effects can often have greater influence on participant knowledge attributions than explicit information about objective probabilities. Thus, our work sheds light on important ways in which participant assessments of actions can affect the epistemic assessments participants make of agents? beliefs. (shrink)

BackgroundPlagiarism is common and threatens the integrity of the scientific literature. However, its detection is time consuming and difficult, presenting challenges to editors and publishers who are entrusted with ensuring the integrity of published literature.MethodsIn this study, the extent of plagiarism in manuscripts submitted to a major specialty medical journal was documented. We manually curated submitted manuscripts and deemed an article contained plagiarism if one sentence had 80 % of the words copied from another published paper. Commercial plagiarism detection software (...) was utilized and its use was optimized.ResultsIn 400 consecutively submitted manuscripts, 17 % of submissions contained unacceptable levels of plagiarized material with 82 % of plagiarized manuscripts submitted from countries where English was not an official language. Using the most commonly employed commercial plagiarism detection software, sensitivity and specificity were studied with regard to the generated plagiarism score. The cutoff score maximizing both sensitivity and specificity was 15 % (sensitivity 84.8 % and specificity 80.5 %).ConclusionsPlagiarism was a common occurrence among manuscripts submitted for publication to a major American specialty medical journal and most manuscripts with plagiarized material were submitted from countries in which English was not an official language. The use of commercial plagiarism detection software can be optimized by selecting a cutoff score that reflects desired sensitivity and specificity. (shrink)

Theological attention to the Catholic doctrine of original sin has a history that extends from the letters of Saint Paul through the Council of Trent and Pius XII’s 1950 encyclical, Humani generis. The doctrine has traditionally been articulated through the Genesis narrative of Adam and Eve as the first human beings from whom all others descend, an account known as monogenism. In the course of the nineteenth century, scientific research into human origins increasingly relied upon polygenism, the descent of humanity (...) from non-human ancestors through a transitional population. Subsequent Catholic engagement with evolution included resistance to polygenism from the Vatican due to a perceived conflict with the doctrine of original sin. Humani generis included a prohibition that remains in place today in spite of widespread de facto acceptance of polygenism among theologians. Understanding the origin and persistence of this disparity stands to benefit from comparison to a corresponding ambivalence toward the sixteenth century Copernican hypothesis of a moving earth, only conclusively resolved in 1992. In Part I of this essay I introduce this historical comparison and describe the origins of monogenism and polygenism terminology in nineteenth century debate over the unity of the human race. I then describe the conceptual changes that transpired during the first half of the twentieth century and the resulting role of polygenism in the nouvelle théologie of the decade prior to Humani generis. Subsequent developments and implications follow in Part II. (shrink)
