What is the temporal course of gratitude and indebtedness and how do these feelings influence helping in the context of reciprocity? In an online-game tapping real-life behaviour, Study 1 (N = 106) finds that while gratitude towards a benefactor remains elevated after an opportunity to reciprocate, indebtedness declines along with helping. Yet, indebtedness rather than gratitude better predicts real-life helping of a benefactor. Using a vignette-based experiment, Study 2 (N = 217) finds that after reciprocation indebtedness and likelihood of helping (...) a benefactor reset to a baseline level while gratitude endures. Furthermore, the decrease in helping after reciprocation is better explained by indebtedness than by gratitude. Study 3 (N = 217) assessed the unique influences of gratitude and indebtedness on helping by comparing contexts in which gratitude is at a baseline level but indebtedness is elevated (e.g. before a monetary payment for a service received) to contexts in which indebtedness is at a baseline level but gratitude is elevated (e.g. after reciprocation of benefits freely given by a friend). People are more likely to help in the former compared to latter context, and this difference is better explained by indebtedness rather than by gratitude. We discuss the interrelated and understudied relationships between gratitude, indebtedness, and reciprocity. (shrink)

Historians of science do not generally indulge in much mythologizing about the founders and prominent figures in our discipline's history. Nevertheless, the received history of the field elides a great deal of the work done on behalf of the Society and its publications because it was tedious, contentious, done in service to discarded aims, performed by underpaid or unacknowledged professional staff, or simply unglamorous. A brief tour through the Society's voluminous if poorly organized archives serves as a corrective.

Brain–Computer Interface research is an interdisciplinary area of study within Neural Engineering. Recent interest in end-user perspectives has led to an intersection with user-centered design. The goal of user-centered design is to reduce the translational gap between researchers and potential end users. However, while qualitative studies have been conducted with end users of BCI technology, little is known about individual BCI researchers’ experience with and attitudes towards UCD. Given the scientific, financial, and ethical imperatives of UCD, we sought to gain (...) a better understanding of practical and principled considerations for researchers who engage with end users. We conducted a qualitative interview case study with neural engineering researchers at a center dedicated to the creation of BCIs. Our analysis generated five themes common across interviews. The thematic analysis shows that participants identify multiple beneficiaries of their work, including other researchers, clinicians working with devices, device end users, and families and caregivers of device users. Participants value experience with device end users, and personal experience is the most meaningful type of interaction. They welcome end-user input, but are skeptical of limited focus groups and case studies. They also recognize a tension between creating sophisticated devices and developing technology that will meet user needs. Finally, interviewees espouse functional, assistive goals for their technology, but describe uncertainty in what degree of function is “good enough” for individual end users. Based on these results, we offer preliminary recommendations for conducting future UCD studies in BCI and neural engineering. (shrink)

Dance is an enjoyable, non-therapy-focused activity that may provide a range of benefits for people with Parkinson’s. The internal simulation of movement through observation, imitation, and imagery, is intrinsic to dance and may contribute to functional improvements for people with Parkinson’s. This study explored the feasibility and potential benefits of a dance program designed by a collaborative team of dance artists, researchers, physiotherapists, and people living with Parkinson’s. The program incorporated motor simulation through observation, imitation and imagery of movement, supported (...) by creative themes, expression, and music. A 6-week pilot trial of the program was conducted with 10 people with Parkinson’s. A focus group following the trial (N= 8) provided insights into the use of imagery, observation and imitation within dance, and the link between creativity and functional outcomes, as well as indicating multidimensional benefits of dance as reported in previous studies. Exploratory outcome measures also suggested potential effects on motor simulation, functional dexterity, and quality of life. The present study demonstrates the feasibility of a co-developed dance program for Parkinson’s and indicates how creative elements of dance may support functional outcomes. Future research should examine the role of motor simulation processes in dance for Parkinson’s, including the potential to develop transferable cognitive-motor skills. This study also highlights the value of collaborative partnerships in designing dance for health programs, which may optimise beneficial effects by using creative approaches to incorporate evidence-based elements, with guidance from individuals with lived experience to ensure the relevance to their goals.

Bioethics has made remarkable progress as a scholarly and applied field. A mere fledgling in the 1960s, it is now firmly established in hospitals, medical schools, and government agencies and boasts a number of professional associations and a handsome collection of journals.

(Anna Maria Taigi 1769 - 1837)St. Alphonsus writes: "a single bad book will be sufficient to cause the destruction of a monastery." Pope Pius XII wrote in 1947 at the beatification of Blessed Maria Goretti: "There rises to Our lips the cry of the Saviour: 'Woe to the world because of scandals!' (Matthew 18:7). Woe to those who consciously and deliberately spread corruption-in novels, newspapers, magazines, theaters, films, in a world of immodesty!" We at St. Pius X Press are (...) calling for a crusade of good books. We want to restore 1,000 old Catholic books to the market. We ask for your assistance and prayers. This book is a photographic reprint of the original. The original has been inspected and many imperfections in the existing copy have been corrected. At Saint Pius X Press our goal is to remain faithful to the original in both photographic reproductions and in textual reproductions that are reprinted. Photographic reproductions are given a page by page inspection, whereas textual reproductions are proofread to correct any errors in reproduction. (shrink)

Pragmatism has enjoyed a considerable revival in the latter part of the twentieth century, but what precisely constitutes pragmatism remains a matter of dispute. In reconstructing the pragmatic tradition in political philosophy, Matthew Festenstein rejects the idea that it is a single, cohesive doctrine. His incisive analysis brings out the commonalities and shared concerns among contemporary pragmatists while making clear their differences in how they would resolve those concerns. His study begins with the work of John Dewey and the (...) moral and psychological conceptions that shaped his philosophy. Here Festenstein lays out the major philosophic issues with which first Dewey, and then his heirs, would grapple. The book's second part traces how Dewey's approach has been differently developed, especially in the work of three contemporary pragmatic thinkers: Richard Rorty, Jurgen Habermas, and Hilary Putnam. This first full-length critical study of the relationship between the pragmatist tradition and political philosophy fills a significant gap in contemporary thought. (shrink)

Nonviolent movements have become a new form of human agency. Between 1900 and 2006, more than 100 such movements appeared, and more than half were successful in dissolving oppression or achieving people's rights. Movements self-organize to summon mass participation, develop cognitive unity in the midst of dissension, and build resilient force on the content of shared beliefs. Some movements may even be a new venue for consciousness that "grows to something of great constancy" as Shakespeare said about "minds transfigured so (...) together."

In "Moral Arguments for Theistic Belief" Robert Merrihew Adams defends a theistic argument from the nature of morality according to which the existence of God is entailed by the divine-command theory, which Adams believes is our best account of morality. In reply I examine the four arguments for the modified divine-command theory that Adams develops in this and later papers, and I show that three of the arguments are much too weak to enable him to make a case for theism (...) in this way and that the fourth itself depends on the assumption that there is a God and so would render that case circular.

Is truth a substantial feature of truth-bearers? Correspondence theorists answer in the affirmative, deflationists in the negative. Correspondence theorists cite in their defense the dependence of truth on meaning or representational content. Deflationists in turn cite the conceptual centrality of simple equivalences such as ''Snow is white' is true iff snow is white'' and 'It is true that snow is white iff snow is white'. The apparent facts to which these theorists appeal correspond to some of our firmest and most (...) basic convictions about truth. An account of truth that fails to accommodate either sort of apparent fact is inadequate. The account presented in this essay attempts to avoid this inadequacy by 'deflating' truth for propositions but 'inflating' truth for entities that express propositions, thus drawing from the insights of both deflationists and correspondence theorists.

Based on a framework that integrates job demands-resources theory, social cognitive theory Handbook of personality, Guilford Press, New York, pp 154–196, 1999) and regulatory focus theory, the purpose of this research is to investigate the relationship between perceptions of organizational politics and subsequent moral disengagement and unethical behavior. We conducted a laboratory study and also collected data in two separate surveys 6 weeks apart from 206 individuals working full time to investigate the relationships presented in our model. In both studies, (...) we examined the direct relationship of politics perceptions on unethical behavior in organizations as well as the indirect relationship through the influence of moral disengagement. We investigated the moderating effect of regulatory focus on the relationship between moral disengagement and unethical behavior using the survey data. Results indicated that perceptions of politics were significantly related to our mediator, moral disengagement, which was significantly related to our dependent variable, unethical behavior. However, only prevention-focus moderated the relationships examined. Implications for future research and managerial practice are discussed. (shrink)

We present evidence for the existence of ‘responsibility voids’ in committee decision-making, that is, the existence of situations where no member of a committee can individually be held morally responsible for the outcome. We analyse three types of reasons (causal, normative and epistemic) for the emergence of responsibility voids, and show that each of them can occur in committees. But the conditions for these voids are so restrictive as to reduce the philosophical or institutional significance they might be thought to (...) possess. (shrink)

Should we remain neutral between our interests and those of future generations? Or are we ethically permitted or even required to depart from neutrality and engage in some measure of intergenerational discounting? This Article addresses the problem of intergenerational discounting by drawing on two different intellectual traditions: the social welfare function (“SWF”) tradition in welfare economics, and scholarship on “prioritarianism” in moral philosophy. Unlike utilitarians, prioritarians are sensitive to the distribution of well-being. They give greater weight to well-being changes affecting (...) worse-off individuals. Prioritarianism can be captured, formally, through an SWF which sums a concave transformation of individual utility, rather than simply summing unweighted utilities in utilitarian fashion. The Article considers the appropriate structure of a prioritarian SWF in intergenerational cases. The simplest case involves a fixed and finite intertemporal population. In that case, I argue, policymakers can and should maintain full neutrality between present and future generations. No discount factor should be attached to the utility of future individuals. Neutrality becomes trickier when we depart from this simple case, meaning: (1) “non-identity” problems, where current choices change the identity of future individuals; (2) population-size variation, where current choices affect not merely the identity of future individuals, but the size of the world’s future population (this case raises the specter of what Derek Parfit terms “the repugnant conclusion,” i.e., that dramatic reductions in the average level of individual well-being might be compensated for by increases in population size); or (3) an infinite population. The Article grapples with the difficult question of outfitting a prioritarian SWF to handle non-identity problems, population-size variation, and infinite populations. It tentatively suggests that a measure of neutrality can be maintained even in these cases. (shrink)

Cappelen and Dever challenge the widely accepted idea that some key aspect of intentional action is essentially indexical. They argue that the classical arguments for this coming from Perry are in fact arguments for a different phenomenon: the opacity of explanatory contexts. I agree with Cappelen and Dever that what Perry says about the ineliminability of indexical terms from explanations of intentional action fails to amount to an argument for this indexicality being essential. But this should not lead us to (...) be sceptics. In this paper, I present a different argument for the essential indexicality of intentional actions. The key premise of this argument is that intentions themselves are essentially indexical. I provide evidence for this premise and defend it against potential criticism. I also show how the essential indexicality of intentions can be used to vindicate Perry's original claims about the essential indexicality of certain beliefs and desires. (shrink)

Philosophy of Science After Feminism is an important contribution to philosophy of science, in that it argues for the central relevance of advances from previous work in feminist philosophy of science and articulates a new vision for philosophy of science going in to the future. Kourany’s vision of philosophy of science’s future as “socially engaged and socially responsible” and addressing questions of the social responsibility of science itself has much to recommend it. I focus the book articulation of an ethical-epistemic (...) ideal for science, the Ideal of Socially Responsible Science, compare it to recent work in the same vein by Heather Douglas, and argue for some advantages of Kourany’s approach. I then ask some critical question about the view, particularly with respect to the source of values that are to be integrated into science and the status of values that are to be so integrated. I argue that Kourany is too sanguine about where the values that inquirers will use come from and that these values seem to be accorded too fixed a status in her account. (shrink)

I wish to examine a rather different way of thinking about permissibility, one according to which, roughly speaking, an agent acts impermissibly if and only if he acts for reasons insufficient to justify him in doing what he does. For reasons that will emerge in Section II, I call this the inferential account of permissibility. I shall not here try to prove that this account is superior to its rivals. My aims are more modest. I shall develop the inferential account, (...) exhibiting some of its attractions along the way, and then show that it is invulnerable to a number of influential objections to the very idea that an agent's reasons for acting could be directly relevant to whether he acts permissibly. If these objections have seemed decisive, it is because we have not considered the full range of possible accounts. The inferential account of permissibility is both plausible and attractive---it deserves to be taken seriously. (shrink)

Kant is gaining popularity in business ethics because the categorical imperative rules out actions such as deceptive advertising and exploitative working conditions, both of which treat people merely as means to an end. However, those who apply Kant in this way often hold businesses themselves morally accountable, and this conception of collective responsibility contradicts the kind of moral agency that underlies Kant's ethics. A business has neither inclinations nor the capacity to reason, so it lacks the conditions necessary for constraint (...) by the moral law. Instead, corporate policies ought to be understood as analogous to legal constraints. They may encourage or discourage certain actions, but they cannot determine a person's maxim - which for Kant is the focus of moral judgment. Because there is no collective intention apart from any intentions of the individual agents who act as members of the corporation, an organization itself has no moral obligations. This poses a dilemma: either apply the categorical imperative to the actions of particular businesspeople and surrender the notion of collective responsibility, or apply a different moral theory to the actions of businesses themselves. Given the diffusion of responsibility in a bureaucracy, the explanatory usefulness of collective responsibility may force business ethicists to abandon Kant's moral philosophy. (shrink)

Businesses frequently exclude spiritual values, viewing such values as impositions that belong in business as much as a priest belongs at a bachelor party. Yet spirituality should not be viewed as impositions from without, but as inclusions from within. Spiritual values should be included in a company to the extent that these values are shared by the principals of a firm. Excluding spiritual values found in a “convergent consensus” runs contrary to freedom and liberty that Milton Friedman, among others, champions. (...) Furthermore, the exclusion of such values from a business threatens to alienate business persons from their moral integrity. By cultivating what I will call “the spiritual imagination,” businesses can facilitate fidelity between the convergent values of its principals, and the actions, policies, and culture of a company.

This paper explores the phenomenology of the Capgras and Cotard delusions. The former is generally characterised as the belief that relatives or friends have been replaced by impostors, and the latter as the conviction that one is dead or has ceased to exist. A commonly reported feature of these delusions is an experienced ''defamiliarisation'' or even ''derealisation'' of things, which is associated with an absence or distortion of affect. I suggest that the importance attributed to affect by current explanations of (...) delusional experience can serve to make explicit the manner in which we ordinarily experience the world under a taken-for-granted aspect of affective familiarity. This implicit feeling is, I argue, partly constitutive of our sense of reality. However, so-called ''folk psychology,'' which is generally adopted by philosophers as an initial interpretive backdrop for delusional beliefs and for beliefs more generally, fails to accommodate it. As a consequence, some pervasive philosophical assumptions concerning the manner in which we experience and understand the world, ourselves, and each other are called into question. (shrink)

A narrowly person-affecting (NPA) axiology is an account of the moral ranking of outcomes such that the comparison of any two outcomes depends on the magnitude and weight of individuals’ well-being gains and losses between the two. This article systematically explores NPA axiology. It argues that NPA axiology yields an outcome ranking that satisfies three fundamental axioms: Pareto, Anonymity and, plausibly, Pigou-Dalton. The axiology is neutral to non-well-being considerations (desert); and (assuming well-being measurability) leads to the Repugnant Conclusion (RC). In (...) short, NPA axiology provides a grounding for Paretian, equity-regarding welfarism, albeit one that includes the RC. (shrink)

Ron Giere’s recent book Scientific perspectivism sets out an account of science that attempts to forge a via media between two popular extremes: absolutist, objectivist realism on the one hand, and social constructivism or skeptical anti-realism on the other. The key for Giere is to treat both scientific observation and scientific theories as perspectives, which are limited, partial, contingent, context-, agent- and purpose-dependent, and pluralism-friendly, while nonetheless world-oriented and modestly realist. Giere’s perspectivism bears significant similarity to earlier ideas of Paul (...) Feyerabend and John Dewey. Comparing these to Giere’s work not only uncovers a consilience of ideas, but also can help to fill out Giere’s account in places where it is not fully developed, as well as helping us understand the work of these earlier authors and their continuing relevance to contemporary concerns in philosophy of science.Keywords: Ronald Giere; Paul Feyerabend; John Dewey; Perspectivism; Pragmatism; Pluralism.

I respond here to an argument in David Shoemaker’s recent essay, “Attributability, Answerability, and Accountability: Toward a Wider Theory of Moral Responsibility.” Shoemaker finds that “Scanlonian” approaches to moral blame err insofar as they do not include a capacity to respond to moral considerations among the conditions on blameworthiness. Shoemaker argues that wrongdoers must be able to respond to moral reasons for their behavior to express the disrespect to which blaming attitudes like resentment respond. I offer reasons for rejecting this (...) argument. (shrink)

I argue that the possibility of non-perceptual experience need not compel a naïve realist to adopt a disjunctive conception of experience. Instead, they can maintain that the nature of perceptual and hallucinatory experience is the same, while still claiming that perceptual experience is presentational of the objects of perception. On such a view the difference between perceptual and non-perceptual experience will lie in the nature of the objects that are so presented. I will defend a view according to which in (...) non-perceptual experience one is presented with mere universals, while in perceptual experience one is presented with the instantiation of a universal by a particular. This is to adopt disjunctivism about the objects of experience, about that which is apparently present in experience. (shrink)

Central to the work of Dominique Lestel is a sustained critical engagement with the sciences of animal behaviour. He critiques the legacy of Cartesianism that sees animals as machines, at the same time as acknowledging the revolution in the understanding of animals that took place in twentieth-century ethology. Further, he offers his own methodological proposals for the future of ethology as a fully social science founded on shared existence and understanding. This profusion of new evidence and edifying approaches demands that (...) we rethink our ideas both of animality and of the nature and origins of culture. (shrink)

I examine the way in which Daniel Dennett (1987, 1995) uses his 'intentional' and 'design' stances to make the claim that intentionality is derived from design. I suggest that Dennett is best understood as attempting to supply an objective, nonintentional, naturalistic rationale for our use of intentional concepts. However, I demonstrate that his overall picture presupposes prior application of the intentional stance in a preconditional, ineliminable,'sense-giving' role. Construed as such, Dennett's account is almost identical to the account of biological teleology (...) offered by Kant in The Critique of Judgement, with the consequence that Dennett's naturalism is untenable. My conclusions lead to doubts concerning the legitimacy of any account attempting to naturalise intentionality by extracting normativity from biology and also point to a novel account of biological function.

Each year, infection with Human Papillomavirus (HPV) leads to millions of abnormal Pap smears and thousands of cases of cervical cancer in the US. Throughout the developing world, where Pap smears are less common, HPV is a leading cause of cancer death among women. So when the international pharmaceutical giant Merck developed a vaccine that could prevent infection with several key strains of HPV, the public health community was anxious to celebrate a major advance. But then marketing and lobbying got (...) in the way. Merck chose to pursue an aggressive lobbying campaign, trying to make its new vaccine mandatory for young girls. The campaign stoked public mistrust about how vaccines come to be mandated, and now it's not just Merck's public image that has taken a hit. The public health community has also been affected. What is the lesson to be learned from this story? Public health communication relies on public trust. (shrink)

In this paper, I consider ways of responding to critiques of natural kinds monism recently suggested from the pluralist camp. Even if monism is determined to be untenable in certain domains (say, about species), it might well be tenable in others. Chemistry is suggested to be such a monist‐friendly domain. Suggestions of trouble for chemical kinds can be defused by attending to the difference between monism as a metaphysical thesis and as a claim about classification systems. Finally, I consider enantiomers (...) as a test case for the monism/pluralism debate. The question of whether enantiomers differ in kind does not appear easily answerable. I suggest that this legislates for pluralism in chemistry. (shrink)

Objectives of socially responsible investment (SRI) are discussed with reference to the two main mechanisms of the SRI ‘movement’: shareholder advocacy and managed investments. We argue that in their current forms, both mechanisms lack the power to create significant corporate change. Shareholder advocacy has been largely unsuccessful to date. Even if resolutions were successful, shareholder advocacy may still be ineffective if underlying economic opportunities remain. Marketing material and investment prospectuses issued by socially responsible mutual funds (SRI funds) commonly contain the (...) claim that, by affecting corporations' access to capital funding, SRI funds can change corporate practices. This paper makes a contribution by presenting the market share of SRI funds in the regions where they are most developed, being Europe, the U.S. and Australia, to show that this claim is unlikely to eventuate. SRI funds also commonly claim that they will outperform conventional active mutual funds. That the economic performances of both are similar might be explained by their similar portfolio compositions. The paper makes an innovation in the SRI literature by adopting a legitimacy framework to explain the continued presence of SRI funds. To achieve desired social and environmental outcomes, SRI funds are urged to address issues at a more systemic level. A suggested mechanism is the collective lobbying of corporations and, especially, governments. (shrink)

This chapter focuses on the phenomenology of mental agency by addressing the question of the ontological category of the conscious mental acts an agent is aware of when engaged in such directed mental activities as conscious calculation and deliberation. An argument is offered for the claim that the mental acts in question must involve phenomenally conscious mental events that have temporal extension. The problem the chapter goes on to address is how to reconcile this line of thought with Geach's arguments (...) for the claim that mental acts like judging lack temporal extension. (shrink)
