This study analyses the sensitivity of public goods contributions through the lens of psychological motives. We report the results of a public goods experiment in which subjects were induced with the motives of care and anger through autobiographical recall. Subjects’ preferences, beliefs, and perceptions under each motive are compared with those of subjects experiencing a neutral autobiographical recall control condition. We find, but only for those subjects with the highest comprehension of the game, that care elicits significantly higher contributions than (...) anger, with the control treatment in between. This positive influence of the care motive on unconditional giving is accounted for partly by preferences for giving and partly by beliefs concerning greater contributions by others. Anger also affects attention to own and other’s payoffs and perceptions of the game’s incentive structure. (shrink)

This paper provides evidence for the following novel insights: (1) People’s economic decisions depend on their psychological motives, which are shaped predictably by the social context. (2) In particular, the social context influences people’s other-regarding preferences, their beliefs and their perceptions. (3) The influence of the social context on psychological motives can be measured experimentally by priming two antagonistic motives—care and anger—in one player towards another by means of an observance or a violation of a fairness norm. Using a mediation (...) approach, we find that the care motive leads to higher levels of cooperation which are driven by more optimistic beliefs, a different perception of the game as well as by a shift towards more pro-social preferences.

Research from psychology, neurobiology and behavioral economics indicates that a binary view of motivation, based on approach and avoidance, may be too reductive. Instead, a literature review suggests that at least seven distinct motives are likely to affect human decisions: “consumption/resource seeking,” “care,” “affiliation,” “achievement,” “status-power,” “threat approach” (or anger), and “threat avoidance” (or fear). To explore the conceptual distinctness and relatedness of these motives, we conducted a semantic categorization task. Here, participants were to assign provided words to one of (...) the motives. By applying principal component analysis to the categorization assignments we represent the semantic inter-relations of these motives on a two-dimensional space, a “semantic atlas.” This atlas suggests that, while care and affiliation are conceptually close, affiliation is closer to threat avoidance (or fear); opposite to these motives we find achievement, consumption and power, with the latter lying closer to threat approach (or anger). In a second study, we asked participants to rate how well the motive-specific words obtained in the first study described their currently experienced feelings. We find that semantically close motives are also more likely to be experienced together, that is, we replicate most of the semantic relations in the “subjective atlas.” We discuss our findings in comparison to other multi-dimensional models of motivation, which show clear similarities. In addition to these motivational atlases, we provide a database of motive-specific words, together with the valence and arousal scores. These can be used for future research on the influence of motives on decision making. (shrink)

What is intellectual humility? In this essay, we aim to answer this question by assessing several contemporary accounts of intellectual humility, developing our own account, offering two reasons for our account, and meeting two objections and solving one puzzle.

This paper extends several themes from recent work on norms of assertion. It does as much by applying those themes to the speech act of asking. In particular, it argues for the view that there is a species of asking which is governed by a certain norm, a norm to the effect that one should ask a question only if one doesn’t know its answer.

This paper argues that questions can be bullshit. First it explores some shallowly interrogative ways in which that can happen. Then it shows how questions can also be bullshit in a way that’s more deeply interrogative.

In 1967, the superior general of the Society of Jesus, Pedro Arrupe, sent a memorandum on the American “racial crisis” to the Jesuit priests, brothers, and social institutions of the United States. Through appeals to the American legal and Catholic moral traditions, On the Interracial Apostolate articulated why Jesuits should strive to achieve racial equality, initiating a historic period of expansion in Jesuit civil rights programs. Given scholars’ limited engagement with On the Interracial Apostolate’s distinctive rhetorical features, this article explains (...) why the document was framed within the discursive framework of prophetic indictment by uncovering the influence of William J. Kenealy, a Jesuit legal scholar, on the document’s drafting. In light of this drafting history, this article concludes by suggesting that the emergence of twentieth-century “Jesuit anti-racism” can, in part, be explained by how questions about racial equality came to be understood as discrete expressions of broader debates about the American legal tradition’s moral foundations.

In this collection, a leading sociologist brings his distinctive method of social criticism to bear on some of the most significant ideas, political and social events, and thinkers of the late twentieth century. In the first section, the author examines several concepts that have figured prominently in recent political-ideological controversies: capitalism, rationality, totalitarianism, power, alienation, left and right, and cultural relativism/ multiculturalism. He considers their origins, historical shifts in their meaning and the myths surrounding them, and their resonance beyond their (...) formal definitions. The second section highlights the author's lifelong interest in the relation of intellectuals to social classes and institutions. The author assesses the notion of a 'New Class', considers the implications for class structure of the increasing centring of intellectual life in the university, and assesses the relation of sociology to professional jargon.

Recent decades have seen a revived interest in super-substantivalism, the idea that spacetime is the only fundamental substance and matter some kind of aspect, property or consequence of spacetime structure. However, the metaphysical debate so far has misidentified a particular variant of super-substantivalism with the position per se. I distinguish between a super-substantival core commitment and different ways of fleshing it out. I then investigate how general relativity and alternative spacetime theories square with the different variants of super-substantivalism.

This book represents a considerable revision and expansion of Public Choice II. Six new chapters have been added, and several chapters from the previous edition have been extensively revised. The discussion of empirical work in public choice has been greatly expanded. As in the previous editions, all of the major topics of public choice are covered. These include: why the state exists, voting rules, federalism, the theory of clubs, two-party and multiparty electoral systems, rent seeking, bureaucracy, interest groups, dictatorship, the (...) size of government, voter participation, and political business cycles. Normative issues in public choice are also examined including a normative analysis of the simple majority rule, Bergson–Samuelson social welfare functions, the Arrow and Sen impossibility theorems, Rawls's social contract theory and the constitutional political economy of Buchanan and Tullock.

I argue that, contrary to folklore, Einstein never really cared for geometrizing the gravitational or the electromagnetic field; indeed, he thought that the very statement that General Relativity geometrizes gravity "is not saying anything at all". Instead, I shall show that Einstein saw the "unification" of inertia and gravity as one of the major achievements of General Relativity. Interestingly, Einstein did not locate this unification in the field equations but in his interpretation of the geodesic equation, the law of motion (...) of test particles. (shrink)

As interpreted by Pattee, von Neumann’s Theory of Self-Reproducing Automata has proved to be a useful tool for understanding some of the difficulties and paradoxes of molecular biosemiotics. But is its utility limited to molecular systems or is it more generally applicable within biosemiotics? One way of answering that question is to look at the Theory as a model for one particular high-level biosemiotic activity, human language. If the model is not useful for language, then it certainly cannot be generally (...) useful to biosemiotics. Beginning with the Universal Turing Machine and continuing with von Neumann’s Theory and Pattee’s interpretation, the properties of universality, programmability, underspecification, complementarity of description/construction, and open-ended evolutionary potential are shown to be usefully applicable to language, thus opening a new line of inquiry in biosemiotics.

I discuss the relationship between different versions of the equivalence principle in general relativity, among them Einstein's equivalence principle, the weak equivalence principle, and the strong equivalence principle. I show that Einstein's version of the equivalence principle is intimately linked to his idea that in GR gravity and inertia are unified to a single field, quite like the electric and magnetic field had been unified in special relativistic electrodynamics. At the same time, what is now often called the strong equivalence (...) principle, related to the local validity of special relativity, can also be found in Einstein's writings, albeit by a different name and clearly separated from what he calls the equivalence principle. I discuss both the development of Einstein's thoughts on the different versions of the equivalence principle, their relationship to the relativity principle, as well as later reflections and variants proposed.

I describe how relativistic field theory generalizes the paradigm property of material systems, the possession of mass, to the requirement that they have a mass–energy–momentum density tensor T µ associated with them. I argue that T µ does not represent an intrinsic property of matter. For it will become evident that the definition of T µ depends on the metric field g µ in a variety of ways. Accordingly, since g µ represents the geometry of spacetime itself, the properties of (...) mass, stress, energy, and momentum should not be seen as intrinsic properties of matter, but as relational properties that material systems have only in virtue of their relation to spacetime structure.

When it originated in the late 19th century, psychometrics was a field with both a scientific and a social mission: psychometrics provided new methods for research into individual differences, and at the same time, these psychometric instruments were considered a means to create a new social order. In contrast, contemporary psychometrics - due to its highly technical nature and its limited involvement in substantive psychological research - has created the impression of being a value-free discipline. In this article, we develop (...) a contrasting characterization of contemporary psychometrics as a value-laden discipline. We expose four such values: that individual differences are quantitative (rather than qualitative), that measurement should be objective in a specific sense, that test items should be fair, and that utility of a model is more important than its truth. Our goal is not to criticize psychometrics for employing these values, but rather to bring them into the open and to show that these values are not inevitable and are in need of systematic evaluation.

The problem of foreknowledge and freedom presents a challenge to the defender of traditional Western theism. Nelson Pike has argued that the existence of an essentially omniscient God who possesses foreknowledge is incompatible with human freedom. Pike's opponents in this matter, among whom is Alvin Plantinga, argue that no incompatibility has yet been shown. I shall develop the view that neither Pike nor his opponents have conclusively settled the question whether foreknowledge and freedom are compatible. Furthermore there is a reason (...) why the issue has not been, and may never be, conclusively settled: it is an inherently paradoxical issue. To aid in demonstrating this point I shall discuss a modified version of a paradox that has come to be known as Newcomb's Problem. (shrink)

Einstein regarded as one of the triumphs of his 1915 theory of gravity - the general theory of relativity - that it vindicated the action-reaction principle, while Newtonian mechanics as well as his 1905 special theory of relativity supposedly violated it. In this paper we examine why Einstein came to emphasise this position several years after the development of general relativity. Several key considerations are relevant to the story: the connection Einstein originally saw between Mach's analysis of inertia and both (...) the equivalence principle and the principle of general covariance, the waning of Mach's influence owing to de Sitter's 1917 results, and Einstein's detailed correspondence with Moritz Schlick in 1920.

While the consequences of mathematically-based software, algorithms and strategies have become ever wider and better appreciated, ethical reflection on mathematics has remained primitive. We review the somewhat disconnected suggestions of commentators in recent decades with a view to piecing together a coherent approach to ethics in mathematics. Calls for a Hippocratic Oath for mathematicians are examined and it is concluded that while lessons can be learned from the medical profession, the relation of mathematicians to those affected by their work is (...) significantly different. There is something to be learned also from the codes of conduct of cognate but professionalised quantitative disciplines such as engineering and accountancy, as well as from legal principles bearing on professional work. We conclude with recommendations that professional societies in mathematics should sponsor an (international) code of ethics, institutional mission statements for mathematicians and syllabuses of ethics courses for incorporation into mathematics degrees.

The problem of motion in general relativity is about how exactly the gravitational field equations, the Einstein equations, are related to the equations of motion of material bodies subject to gravitational fields. This article compares two approaches to derive the geodesic motion of matter from the field equations: the ‘T approach’ and the ‘vacuum approach’. The latter approach has been dismissed by philosophers of physics because it apparently represents material bodies by singularities. I argue that a careful interpretation of the (...) approach shows that it does not depend on introducing singularities at all and that it holds at least as much promise as the T approach. (shrink)

In the past decades, reductionism has dominated both research directions and funding policies in clinical psychology and psychiatry. The intense search for the biological basis of mental disorders, however, has not resulted in conclusive reductionist explanations of psychopathology. Recently, network models have been proposed as an alternative framework for the analysis of mental disorders, in which mental disorders arise from the causal interplay between symptoms. In this target article, we show that this conceptualization can help explain why reductionist approaches in (...) psychiatry and clinical psychology are on the wrong track. First, symptom networks preclude the identification of a common cause of symptomatology with a neurobiological condition; in symptom networks, there is no such common cause. Second, symptom network relations depend on the content of mental states and, as such, feature intentionality. Third, the strength of network relations is highly likely to depend partially on cultural and historical contexts as well as external mechanisms in the environment. Taken together, these properties suggest that, if mental disorders are indeed networks of causally related symptoms, reductionist accounts cannot achieve the level of success associated with reductionist disease models in modern medicine. As an alternative strategy, we propose to interpret network structures in terms of D. C. Dennett's (1987) notion ofreal patterns, and suggest that, instead of being reducible to a biological basis, mental disorders feature biological and psychological factors that are deeply intertwined in feedback loops. This suggests that neither psychological nor biological levels can claim causal or explanatory priority, and that a holistic research strategy is necessary for progress in the study of mental disorders.

The story of the greatest of all philosophical friendships—and how it influenced modern thought David Hume is widely regarded as the most important philosopher ever to write in English, but during his lifetime he was attacked as “the Great Infidel” for his skeptical religious views and deemed unfit to teach the young. In contrast, Adam Smith was a revered professor of moral philosophy, and is now often hailed as the founding father of capitalism. Remarkably, the two were best friends for (...) most of their adult lives, sharing what Dennis Rasmussen calls the greatest of all philosophical friendships. The Infidel and the Professor is the first book to tell the fascinating story of the friendship of these towering Enlightenment thinkers—and how it influenced their world-changing ideas. The book follows Hume and Smith’s relationship from their first meeting in 1749 until Hume’s death in 1776. It describes how they commented on each other’s writings, supported each other’s careers and literary ambitions, and advised each other on personal matters, most notably after Hume’s quarrel with Jean-Jacques Rousseau. Members of a vibrant intellectual scene in Enlightenment Scotland, Hume and Smith made many of the same friends, joined the same clubs, and were interested in many of the same subjects well beyond philosophy and economics—from psychology and history to politics and Britain’s conflict with the American colonies. The book reveals that Smith’s private religious views were considerably closer to Hume’s public ones than is usually believed. It also shows that Hume contributed more to economics—and Smith contributed more to philosophy—than is generally recognized. Vividly written, The Infidel and the Professor is a compelling account of a great friendship that had great consequences for modern thought. (shrink)

The Aristotelian dictum that desire is the starting point of practical reasoning that ends in action can of course be denied. Its denial is a commonplace of moral theory in the tradition of Kant. But in this essay I am concerned with that issue only indirectly. I shall not contend that rational action always or necessarily does involve desire as its starting point; nor shall I deny it. My question concerns instead the possibility of its ever beginning in desire. For (...) there is a question whether it is even possible for reasoning to begin in desire, a question arising from the nature of desire and its objects, which to my knowledge has not been articulated. If we can see how desire can provide the arche of action, then we can consider later, and from that vantage point, whether it is necessary that it should do so. It will, I think, be possible eventually to argue that if practical reasoning has the character it must have, if it can begin in desire, then its starting point can be nothing but desire. (shrink)

WHILE THERE IS AGREEMENT AMONG MANY (BUT NOT ALL) THEOLOGIANS AND PHILOSOPHERS THAT A MIRACULOUS EVENT SHOULD BE CONCEIVED IN OPPOSITION TO THE NATURAL ORDER, THERE IS DISAGREEMENT ABOUT WHY THIS OPPOSITION MUST BE PRESENT.

I ARGUE THAT IF MIRACLES ARE TO BE THOUGHT OF AS SUPERNATURAL INTERVENTIONS INTO THE (...) NATURAL WORLD, AND HENCE IT IS THOUGHT APPROPRIATE TO SPEAK OF THEM AS PHYSICALLY IMPOSSIBLE, THEN ONE MUST DEFINE THE PHYSICALLY IMPOSSIBLE IN TERMS OF WHAT CAN BE EXPLAINED ONLY BY REFERENCE TO SUPERNATURAL FORCE, RATHER THAN IN TERMS OF WHAT IS LOGICALLY INCONSISTENT WITH LAWS OF NATURE.

This contributed volume is the result of a July 2010 workshop at the University of Wuppertal Interdisciplinary Centre for Science and Technology Studies which brought together world-wide experts from physics, philosophy and history, in order to address a set of questions first posed in the 1950s: How do we compare spacetime theories? How do we judge, objectively, which is the “best” theory? Is there even a unique answer to this question? -/- The goal of the workshop, and of this book, (...) is to contribute to the development of a meta-theory of spacetime theories. Such a meta-theory would reveal insights about specific spacetime theories by distilling their essential similarities and differences, deliver a framework for a class of theories that could be helpful as a blueprint to build other meta-theories, and provide a higher-level viewpoint for judging which theory most accurately describes nature. But rather than drawing a map in broad strokes, the focus is on particularly rich regions in the “space of spacetime theories.” -/- This work will be of interest to physicists, as well as philosophers and historians of science working with or interested in General Relativity and/or Space, Time and Gravitation more generally.

Refinements in Darwin’s theory of the origin of a moral sense create a framework equipped to organize and integrate contemporary theory and research on morality. Morality originated in deferential, cooperative, and altruistic ‘‘social instincts,’’ or decision-making strategies, that enabled early humans to maximize their gains from social living and resolve their conflicts of interest in adaptive ways. Moral judgments, moral norms, and conscience originated from strategic interactions among members of groups who experienced confluences and conflicts of interest. Moral argumentation buttressed (...) by moral reasoning is equipped to generate universal and impartial moral standards. Moral beliefs and standards are products of automatic and controlled information-processing and decision making mechanisms. To understand how people make moral decisions, we must understand how early evolved mechanisms in the old brain and recently evolved mechanisms in the new brain are activated and how they interact. Understanding what a sense of morality is for helps us understand what it is. (shrink)

Role modeling is widely thought to be a principal vehicle for acquiring the virtues. Yet, little is known about role modeling as a process. This paper surveys the behavioral sciences for insights about how one person can find the actions of another person so inspirational that the person attempts to reproduce the behavior in question. In general, such inspiration occurs when an observer sees a model similar to herself, wrestling with a problem she is having, such that the model’s accomplishments (...) are seen as attainable. When the behavior modeled is moral, additional complications arise, not the least of which is the contemporary skepticism about anyone held up as a hero. The paper concludes with some suggestions about how organizations can facilitate the development of the virtues through role modeling. (shrink)

The call for 'sustainable degrowth' has recently turned into a focal point of critical social and ecological debate, as well as a framework for diverse strands of activism. So far, little is known about the motives, attitudes and practices of grassroots activists within the degrowth spectrum. This article presents results of a survey conducted at the 2014 International Degrowth Conference, revealing both the presence of a widely shared basic consensus among respondents and their broad division into five distinguishable sub-currents. A (...) cluster analysis shows that degrowth provides a framework for a diversity of critical and transformational approaches. We identify and describe five such currents: eco-radical sufficiency-oriented critics of civilisation; moderate immanent reformers; a transitory group of voluntarist-pacifist idealists; the modernist rationalist Left; and the alternative practical Left.

ABSTRACT:Practical wisdom has received scant attention in business ethics. Defined as a disposition toward cleverness in crafting morally excellent responses to, or in anticipation of, challenging particularities, practical wisdom has four psychological components: knowledge, emotion, thinking, and motivation. People's experience, reflection, and inspiration are theorized to determine their capacity for practical wisdom-related performance. Enhanced by their abilities to engage in moral imagination, systems thinking, and ethical reframing, this capacity is realized in the form of wisdom-related performance. This can be manifested (...) either in wise business decisions or through their performance as mentors, advice givers, or dispute handlers. (shrink)

Top-down feedback does not benefit speech recognition; on the contrary, it can hinder it. No experimental data imply that feedback loops are required for speech recognition. Feedback is accordingly unnecessary and spoken word recognition is modular. To defend this thesis, we analyse lexical involvement in phonemic decision making. TRACE (McClelland & Elman 1986), a model with feedback from the lexicon to prelexical processes, is unable to account for all the available data on phonemic decision making. The modular Race model (Cutler (...) & Norris 1979) is likewise challenged by some recent results, however. We therefore present a new modular model of phonemic decision making, the Merge model. In Merge, information flows from prelexical processes to the lexicon without feedback. Because phonemic decisions are based on the merging of prelexical and lexical information, Merge correctly predicts lexical involvement in phonemic decisions in both words and nonwords. Computer simulations show how Merge is able to account for the data through a process of competition between lexical hypotheses. We discuss the issue of feedback in other areas of language processing and conclude that modular models are particularly well suited to the problems and constraints of speech recognition. Key Words: computational modeling; feedback; lexical processing; modularity; phonemic decisions; reading; speech recognition; word recognition. (shrink)

The current research investigates how religiosity can influence unethicality in a consumption context. In particular, considering the link between extrinsic religious orientations and unethicality, this research clarifies why and when extrinsic religiosity leads to unethical decisions. Across two studies, findings show that ethnocentrism is both a mediator and a moderator of the effects of extrinsic religiosity on consumers’ ethical judgments. This is because extrinsic religiosity leads to ethnocentrism, and in-group loyalty manifested through ethnocentrism increases support for unethical consumer actions, thus (...) establishing ethnocentrism as a mediator. At the same time, different levels of ethnocentrism can also influence how extrinsic religiosity leads to supporting unethical consumption via self-righteousness, thus establishing ethnocentrism as a moderator. The findings from this research have significant implications for diverse stakeholders who have an interest in religiosity and consumer behavior. (shrink)

Various studies on the impact of religiousness on consumer ethics have produced mixed results and suggested further clarification on the issue. Therefore, this article examines the effect of religiousness, materialism, and long-term orientation on consumer ethics in Indonesia. The results from 356 respondents in Indonesia, the largest Muslim population in the world, showed that intrinsic religiousness positively affected consumer ethics, while extrinsic social religiousness negatively affected consumer ethics. However, extrinsic personal religiousness did not affect consumer ethical beliefs dimensions. Unlike other (...) studies in developed countries, materialism and long-term orientation influenced only a few of the consumer ethical beliefs dimensions in this study. To date, the study is one of the first empirical studies to explore the impact of religiousness on consumer ethics in Indonesia. The study contributes to the debate on the impact of religiousness on consumer ethics and can assist managers and public policymakers in their effort to mitigate unethical consumer activities in Indonesia.

Abstract:Recent developments in personality research point to an alchemy of character composed of five elements: extroversion, agreeableness, conscientiousness, neuroticism, and openness to experience. This paper surveys this research for its implications to the study of the virtues in organizational ethics. After subjecting each of these five character traits to several tests as to what constitutes a virtue, the empirical evidence supports an organizational virtue of agreeableness and an organizational virtue of conscientiousness. Although the empirical evidence falls short, an argument is (...) mobilized on behalf of an additional organizational virtue of openness to experience. (shrink)

Moral imagination is a process that involves a thorough consideration of the ethical elements of a decision. We sought to explore what might distinguish moral imagination from other ethical approaches within a complex business simulation. Using a three-component model of moral imagination, we sought to discover whether organization cultures with a salient ethics theme activate moral imagination. Finding an effect, we sought an answer to whether some individuals were more prone to being influenced in this way by ethical cultures. We (...) found that employees with strong moral identities are less influenced by such cultures than employees whose sense of self is not defined in moral terms. (shrink)

A fascinating recent turn in epistemology focuses on inquiring attitudes like wondering and being curious. Many have argued that these attitudes are governed by norms similar to those that govern our doxastic attitudes. Yet, to date, this work has only considered norms that might *prohibit* having certain inquiring attitudes (``norms of restriction''), while ignoring those that might *require* having them (``norms of expansion''). We aim to address that omission by offering a framework that generates norms of expansion for inquiring attitudes. (...) The framework draws on inferential erotetic logic, which we explain and augment with some theorems. We explore several of the norms that it yields - some sympathetically, others unsympathetically.

For most observers of economics from both inside and outside the science, the term ‘economics’ is synonymous with neoclassical economics. It is the methodology of neoclassical economics that defines the discipline of economics. ‘Mainstream economics’ is neoclassical economics and anyone entering the discipline today who wishes to obtain an appointment at one of the leading universities of the world is well advised to master its techniques. The fact that virtually every winner of a Nobel prize from Paul Samuelson up to (...) his student Joseph Stiglitz has been a practitioner of neoclassical economics is ample proof of the methodology’s triumph. Despite the dominance of this methodology, however, neoclassical economics has been subject to a steady stream of criticisms and proposals for alternative methodological approaches throughout its life. This article focuses on two relatively recent challenges to the neoclassical orthodoxy that seem to have taken hold of a non-negligible minority of the profession, some of whom can be found at leading universities. These two challenges come from behavioural economics and evolutionary economics. The article describes the strengths and weaknesses of both of these methodological approaches and contrasts them with that of neoclassical economics. It concludes that all three methodologies have something positive to contribute to the study of human behaviour. Key Words: neoclassical economics • behavioural economics • evolutionary economics.
