When the side effect of an action involves moral considerations (e.g. when a chairman’s pursuit of profits harms the environment) it tends to influence theory-of-mind judgments. On average, bad side effects are judged intentional whereas good side effects are judged unintentional. In a series of two experiments, we examined the largely uninvestigated roles of individual differences in this judgment asymmetry. Experiment 1 indicated that extraversion accounted for variations in intentionality judgments, controlling for a range of other general individual differences (e.g. (...) working memory, self-control). Experiment 2 indicated that extraversion’s influence was partially mediated by more specific variations in intentional action concepts. A priming manipulation also provided causal evidence of judgment instability and bias. Results suggest that the intentional action judgment asymmetry is multiply determined, reflecting the interplay of individual differences and judgment biases. Implications and the roles of individual differences in judgment and decision-making research are discussed. (shrink)

Recently, there has been an increased interest in folk intuitions about freedom and moral responsibility from both philosophers and psychologists. We aim to extend our understanding of folk intuitions about freedom and moral responsibility using an individual differences approach. Building off previous research suggesting that there are systematic differences in folks’ philosophically relevant intuitions, we present new data indicating that the personality trait extraversion predicts, to a significant extent, those who have compatibilist versus incompatibilist intuitions. We argue that identifying groups (...) of people who have specific and diverse intuitions about freedom and moral responsibility offers the possibility for theoretical advancement in philosophy and psychology, and may in part explain why some perennial philosophical debates have proven intractable. (shrink)

Our theoretical understanding of individual differences can be used as a tool to test and refine theory. Individual differences are useful because judgments, including philosophically relevant intuitions, are the predictable products of the fit between adaptive psychological mechanisms (e.g., heuristics, traits, skills, capacities) and task constraints. As an illustration of this method and its potential implications, our target article used a canonical, representative, and affectively charged judgment task to reveal a relationship between the heritable personality trait extraversion and some compatabilist (...) judgments. In the current Reply, we further clarify major theoretical implications of these data and outline potential opportunities and obstacles for this methodology. Discussion focuses on (1) the need for theoretically grounded a priori predictions; (2) the use of precise process level data and theory; (3) the possibility of convergent validity as personality is known to predict life experiences and outcomes; and (4) the fundamentally adaptive nature of cognition. (shrink)

Although it makes some progress, McKay & Dennett's (M&D's) proposal is limited because (1) the argument for adaptive misbelief is not new, (2) arguments overextend the evidence provided, and (3) the alleged sufficient conditions are not as prohibitive as suggested. We offer alternative perspectives and evidence, including individual differences research, indicating that adaptive misbeliefs are likely much more widespread than implied.

Many philosophers appeal to intuitions to support some philosophical views. However, there is reason to be concerned about this practice as scientific evidence has documented systematic bias in philosophically relevant intuitions as a function of seemingly irrelevant features (e.g., personality). One popular defense used to insulate philosophers from these concerns holds that philosophical expertise eliminates the influence of these extraneous factors. Here, we test this assumption. We present data suggesting that verifiable philosophical expertise in the free will debate-as measured by (...) a reliable and validated test of expert knowledge-does not eliminate the influence of one important extraneous feature (i.e., the heritable personality trait extraversion) on judgments concerning freedom and moral responsibility. These results suggest that, in at least some important cases, the expertise defense fails. Implications for the practice of philosophy, experimental philosophy, and applied ethics are discussed.

We explore and provide an account for a recently identified judgment anomaly, i.e., an order effect that changes the strength of intentionality ascriptions for some side effects (e.g., when a chairman's pursuit of profits has the foreseen but unintended consequence of harming the environment). Experiment 1 replicated the previously unanticipated order effect anomaly controlling for general individual differences. Experiment 2 revealed that the order effect was multiply determined and influenced by factors such as beliefs (i.e., that the same actor was (...) involved in bringing about both good and bad side effects) and philosophical training (i.e., more training was associated with smaller differences in judgment when harm followed help). Results provide more evidence that the folk's philosophically relevant intuitions are predictably fragmented and depend on the dynamic interplay between persons, process, and environments. Methodological and theoretical implications are discussed. (shrink)

Perhaps personality traits substantially influence one’s philosophically relevant intuitions. This suggestion is not only possible, it is consistent with a growing body of empirical research: Personality traits have been shown to be systematically related to diverse intuitions concerning some fundamental philosophical debates. We argue that this fact, in conjunction with the plausible principle that almost all adequate philosophical views should take into account all available and relevant evidence, calls into question some prominent approaches to traditional philosophical projects. To this end, (...) we present the Philosophical Personality Argument (PPA). We explain how it supports the growing body of evidence challenging some of the uses of intuitions in philosophy, and we defend it from some criticisms of empirically based worries about intuitions in philosophy. We conclude that the current evidence indicates that the PPA is sound, and thus many traditional philosophical projects that use intuitions must become substantially more empirically oriented.

Visual aids can improve comprehension of risks associated with medical treatments, screenings, and lifestyles. Do visual aids also help decision makers accurately assess their risk comprehension? That is, do visual aids help them become well calibrated? To address these questions, we investigated the benefits of visual aids displaying numerical information and measured accuracy of self-assessment of diagnostic inferences (i.e., metacognitive judgment calibration) controlling for individual differences in numeracy. Participants included 108 patients who made diagnostic inferences about three medical tests on (...) the basis of information about the sensitivity and false-positive rate of the tests and disease prevalence. Half of the patients received the information in numbers without a visual aid, while the other half received numbers along with a grid representing the numerical information. In the numerical condition, many patients --especially those with low numeracy-- misinterpreted the predictive value of the tests and profoundly overestimated the accuracy of their inferences. Metacognitive judgment calibration mediated the relationship between numeracy and accuracy of diagnostic inferences. In contrast, in the visual aid condition, patients at all levels of numeracy showed high-levels of inferential accuracy and metacognitive judgment calibration. Results indicate that accurate metacognitive assessment may explain the beneficial effects of visual aids and numeracy --a result that accords with theory suggesting that metacognition is an essential part of risk literacy. We conclude that well-designed risk communications can inform patients about health-relevant numerical information while helping them assess the quality of their own risk comprehension. (shrink)

In the free will literature, some compatibilists and some incompatibilists claim that their views best capture ordinary intuitions concerning free will and moral responsibility. One goal of researchers working in the field of experimental philosophy has been to probe ordinary intuitions in a controlled and systematic way to help resolve these kinds of intuitional stalemates. We contribute to this debate by presenting new data about folk intuitions concerning freedom and responsibility that correct for some of the shortcomings of previous studies. (...) These studies also illustrate some problems that pertain to all of the studies that have been run thus far. (shrink)

The past ten years have seen multiple attempts to estimate the relation between the global personality trait extraversion and compatibilist free will judgments. Here, we contribute to that line of research by conducting a meta-analysis of 17 published and eight unpublished studies (N = 2,811) estimating that relation. Overall, the mean effect size was modest but remarkably robust across materials, locations, and labs (z =.19, 95% CI.15-.24, p <.001). No significant publication bias was detected in the studies (t (23) = (...) 1.88, p =.07). While there was no significant heterogeneity in the studies (Q (24) = 34.42, p =.08, I2 = 26.05), a moderator analysis suggested that the effect is strongest in cases that contain highly affective actions (e.g., murder) (z =.22, 95% CI.17-.28, p <.001) and weakest in cases that contain actions with low affect (e.g., asking whether free will is compatible with determinism) (z =.09, 95% CI -.05-.23, p =.22). The meta-analysis provides additional evidence that extraversion is related to compatibilist free will judgments and helps to identify opportunities to discover boundary conditions and more proximal causal mechanisms for the relation. The results of the meta-analysis also have implications for informed decision making. (shrink)

We review evidence showing that disagreement in folk and expert philosophical intuitions can be predicted by global, heritable personality traits. The review focuses on recent studies of intuitions about free will, ethics, and intentional action. These findings are philosophically important because they suggest that while some projects cannot be done, other projects must take individual differences in philosophical character into account. But care needs to be taken when interpreting the implications of these individual differences. We illustrate one way that these (...) differences have been abused. We then illustrate two ways that these findings can be legitimately used to help illuminate philosophical issues. Given the large and readily available body of evidence, neglect of persistent and predictable philosophical differences is irresponsible. (shrink)

It is commonly claimed that fully virtuous individuals cannot be ignorant and that everyday intuitions support this fact. Others maintain that there are virtues of ignorance and most people recognize them. Both views cannot be correct. We report evidence from three experiments suggesting that ignorance does not rule out folk attributions of virtue. Additionally, results show that many of these judgments can be predicted by one’s emotional stability—a heritable personality trait. We argue that these results are philosophically important for the (...) study of virtue and we discuss some of the ways individual differences may inform and facilitate current debates in ethics. We close with a cautionary argument detailing the risks of discounting some intuitions simply because they are associated with seemingly less desirable personality traits. (shrink)

Evaluational internalism holds that only features internal to agency (e.g., motivation) are relevant to attributions of virtue [Slote, M. (2001). Morals from motives. Oxford: Oxford University Press]. Evaluational externalism holds that only features external to agency (e.g., consequences) are relevant to attributions of virtue [Driver, J. (2001). Uneasy virtue. Cambridge: Cambridge University Press]. Many evaluational externalists and internalists claim that their view best accords with philosophically naïve (i.e., folk) intuitions, and that accordance provides argumentative support for their view. Evaluational internalism (...) and externalism are incompatible views and therefore it is impossible that both views are supported by most folk intuitions. In four experiments, we present evidence that neither pure evaluational internalism nor pure evaluational externalism accurately capture some relevant folk intuitions about virtue. However, our experiments suggest external factors are vastly more important than internal factors for folk attributions of virtue. While these data do not entail that evaluational internalism and externalism about virtue are false, they situate important argumentative burdens, constrain philosophical theory about virtue, and illustrate a valuable method that could foster more efficient progress in ethics.

Oaksford & Chater (O&C) focus on patterns of typical adult reasoning from a probabilistic perspective. We discuss implications of extending the probabilistic approach to lifespan development, considering the role of working memory, strategy use, and expertise. Explaining variations in human reasoning poses a challenge to Bayesian rational analysis, as it requires integrating knowledge about cognitive processes.

Heritable personality traits often predict fundamental philosophical disagreement. This conclusion is based on studies of more than 15,000 people sampled from diverse cultures and educational backgrounds, including verifiable experts. In this chapter, we review some of this research showing links between personality and philosophical bias in free will, intentional action, and ethics. Our discussion focuses on serious challenges that these philosophical biases pose (e.g., limits on the use of philosophical intuitions as evidence). We close with discussion of the Philosophical Personality (...) Argument and brief consideration of emerging projects in applied experimental philosophy. (shrink)

Some theorists argue that appropriate responses to terrorism are in part shaped by popular sentiment. In two experiments, using representative design and ecological stimuli (e.g. actual news reports), we present evidence for some of the ways popular sentiment about terrorism tracks theory and can be constructed. In Experiment 1, we document that using the word ‘terrorist’ to describe a group of people decreases willingness to understand the group's grievances, decreases willingness to negotiate with the group, increases perceived permissibility of violence (...) against the group, and decreases the perceived rationality of the group. In Experiment 2, we demonstrate that judgment about the permissibility of the use of force against terrorist groups can be biased by simple memory-priming manipulations. Results are interpreted in terms of (1) implications for philosophical theories about terrorism and (2) the role that experimental investigation can play in applied ethics. (shrink)

Throughout his early career, Sir Edward Coke joined many of his contemporaries in his concern about the uncertainty of the common law. Coke attributed this uncertainty to the ignorance and entrepreneurship of practitioners, litigants, and other users of legal power whose actions eroded confidence in the law. Working to limit their behaviours, Coke also simultaneously sought to strengthen royal authority and the Reformation settlement. Yet the tensions in his thought led him into conflict with James I, who had accepted (...) many of the criticisms of the common law. Sir Edward Coke and the Reformation of the Laws reframes the origins of Coke's legal thought within the context of law reform and provides a new interpretation of his early career, the development of his legal thought, and the path from royalism to opposition in the turbulent decades leading up to the English civil wars.

In this paper, we examine Adam Feltz and Edward Cokely’s recent claim that “the personality trait extraversion predicts people’s intuitions about the relationship of determinism to free will and moral responsibility”. We will first present some criticisms of their work before briefly examining the results of a recent study of our own. We argue that while Feltz and Cokely have their finger on the pulse of an interesting and important issue, they have not established a robust and (...) stable connection between extraversion and compatibilist-friendly intuitions.

In four experiments, we offer evidence that virtues are often judged as uniquely important for some business practices (e.g., hospital management and medical error investigation). Overall, actions done only from virtue (either by organizations or individuals) were judged to feel better, to be more praiseworthy, to be more morally right, and to be associated with more trustworthy leadership and greater personal life satisfaction compared to actions done only to produce the best consequences or to follow the correct moral rule. These (...) results accord with claims made by some virtue ethicists. The current data contribute to a small but growing body of literature emphasizing both empirical soundness and philosophical rigor in the scientific study of virtue. Results also offer some guidance concerning how businesses, employees, and executives are evaluated and perceived. Implications for theory and practice are discussed. (shrink)

Understanding the folk notion of free will and moral responsibility is important for a host of applied and theoretical issues in psychology, philosophy, and ethics. The bulk of experimental research has focused on folk intuitions concerning determinism's relation to free will and moral responsibility. However, determinism is a difficult term for many folk to understand. Accordingly researchers often use comprehension questions to identify and exclude large proportions of participants who seem to struggle with relevant concepts. Here, we document some of (...) the cognitive mechanisms involved in folk judgments related to comprehension of determinism, and its relations to free will and moral responsibility. Results provide prescriptions for experimental designs that can increase comprehension, potentially decreasing sampling biases. Theoretical and methodological implications are discussed. (shrink)

This book presents a systematic account of the role of the personal spiritual ideal of wu-wei--literally "no doing," but better rendered as "effortless action"--in early Chinese thought. Edward Slingerland's analysis shows that wu-wei represents the most general of a set of conceptual metaphors having to do with a state of effortless ease and unself-consciousness. This concept of effortlessness, he contends, serves as a common ideal for both Daoist and Confucian thinkers. He also argues that this concept contains within itself (...) a conceptual tension that motivates the development of early Chinese thought: the so-called "paradox of wu-wei," or the question of how one can consciously "try not to try." Methodologically, this book represents a preliminary attempt to apply the contemporary theory of conceptual metaphor to the study of early Chinese thought. Although the focus is upon early China, both the subject matter and methodology have wider implications. The subject of wu-wei is relevant to anyone interested in later East Asian religious thought or in the so-called "virtue-ethics" tradition in the West. Moreover, the technique of conceptual metaphor analysis--along with the principle of "embodied realism" upon which it is based--provides an exciting new theoretical framework and methodological tool for the study of comparative thought, comparative religion, intellectual history, and even the humanities in general. Part of the purpose of this work is thus to help introduce scholars in the humanities and social sciences to this methodology, and provide an example of how it may be applied to a particular sub-field.

National Book Award Finalist. How did humanity originate and why does a species like ours exist on this planet? Do we have a special place, even a destiny in the universe? Where are we going, and perhaps, the most difficult question of all, "Why?" In The Meaning of Human Existence, his most philosophical work to date, Pulitzer Prize–winning biologist Edward O. Wilson grapples with these and other existential questions, examining what makes human beings supremely different from all other species. (...) Searching for meaning in what Nietzsche once called "the rainbow colors" around the outer edges of knowledge and imagination, Wilson takes his readers on a journey, in the process bridging science and philosophy to create a twenty-first-century treatise on human existence—from our earliest inception to a provocative look at what the future of mankind portends. Continuing his groundbreaking examination of our "Anthropocene Epoch," which he began with The Social Conquest of Earth, described by the New York Times as "a sweeping account of the human rise to domination of the biosphere," here Wilson posits that we, as a species, now know enough about the universe and ourselves that we can begin to approach questions about our place in the cosmos and the meaning of intelligent life in a systematic, indeed, in a testable way. Once criticized for a purely mechanistic view of human life and an overreliance on genetic predetermination, Wilson presents in The Meaning of Human Existence his most expansive and advanced theories on the sovereignty of human life, recognizing that, even though the human and the spider evolved similarly, the poet's sonnet is wholly different from the spider's web. Whether attempting to explicate "The Riddle of the Human Species," "Free Will," or "Religion"; warning of "The Collapse of Biodiversity"; or even creating a plausible "Portrait of E.T.," Wilson does indeed believe that humanity holds a special position in the known universe. The human epoch that began in biological evolution and passed into pre-, then recorded, history is now more than ever before in our hands. Yet alarmed that we are about to abandon natural selection by redesigning biology and human nature as we wish them, Wilson soberly concludes that advances in science and technology bring us our greatest moral dilemma since God stayed the hand of Abraham.

This paper investigates the question of, and the degree to which, Newton’s theory of space constitutes a third-way between the traditional substantivalist and relationist ontologies, i.e., that Newton judged that space is neither a type of substance/entity nor purely a relation among such substances. A non-substantivalist reading of Newton has been famously defended by Howard Stein, among others; but, as will be demonstrated, these claims are problematic on various grounds, especially as regards Newton’s alleged rejection of the traditional substance/accident dichotomy (...) concerning space. Nevertheless, our analysis of the metaphysical foundations of Newton’s spatial theory will strive to uncover its unique and innovative characteristics, most notably, the distinctive role that Newton’s “immaterialist” spatial ontology plays in his dynamics.

As the usual regulatory framework did not fit well during the last Ebola outbreak, innovative thinking still needed. In the absence of an outbreak, randomised controlled trials of clinical efficacy in humans cannot be done, while during an outbreak such trials will continue to face significant practical, philosophical, and ethical challenges. This article argues that researchers should also test the safety and effectiveness of novel vaccines in wild apes by employing a pluralistic approach to evidence. There are three reasons to (...) test vaccines in wild populations of apes: i) protect apes; ii) reduce Ebola transmission from wild animals to humans; and iii) accelerate vaccine development and licensing for humans. Data obtained from studies of vaccines among wild apes and chimpanzees may even be considered sufficient for licensing new vaccines for humans. This strategy will serve to benefit both wild apes and humans. (shrink)

If by “demon” one understands an evil occult being, then its equivalent in the Islamic narrative is the intersection of the category jinn with that of the shayātīn: a demon is a shaytān from among the jinn. The literature in the Islamic tradition on these subjects is vast. In what follows, we will select some key elements from it to provide a brief summary: first on the nature of the jinn, their nature, and their relationship to God and human beings; (...) second, on the origin, nature, and role of Shaytān (Satan himself) and the shayātīn in the moral drama of Islam. Then, we will take a closer look at the relationship between jinn and humankind, according to Islam, and the phenomena of the demonic as it manifests itself in that relation. In the process, I will entertain, tentatively, some philosophical speculation as to the nature of that ultimately mysterious relation and phenomena, drawn from what we find in the religious sources.

Reassesses the philosophical and pedagogical contributions of Protagoras Protagoras and Logos brings together in a meaningful synthesis the contributions and rhetoric of the first and most famous of the Older Sophists, Protagoras of Abdera. Most accounts of Protagoras rely on the somewhat hostile reports of Plato and Aristotle. By focusing on Protagoras's own surviving words, this study corrects many long-standing misinterpretations and presents significant facts: Protagoras was a first-rate philosophical thinker who positively influenced the theories of Plato and Aristotle, and (...) Protagoras pioneered the study of language and was the first theorist of rhetoric. In addition to illustrating valuable methods of translating and reading fifth-century B.C.E. Greek passages, the book marshals evidence for the important philological conclusion that the Greek word translated as rhetoric was a coinage by Plato in the early fourth century. -/- In this second edition, Edward Schiappa reassesses the philosophical and pedagogical contributions of Protagoras. Schiappa argues that traditional accounts of Protagoras are hampered by mistaken assumptions about the Sophists and the teaching of the art of rhetoric in the fifth century. He shows that, contrary to tradition, the so-called Older Sophists investigated and taught the skills of logos, which is closer to modern conceptions of critical reasoning than of persuasive oratory. Schiappa also offers interpretations for each of Protagoras's major surviving fragments and examines Protagoras's contributions to the theory and practice of Greek education, politics, and philosophy. In a new afterword Schiappa addresses historiographical issues that have occupied scholars in rhetorical studies over the past ten years, and throughout the study he provides references to scholarship from the last decade that has refined his views on Protagoras and other Sophists.

Perhaps the two main contemporary formulations of ethical naturalism – Synthetic Ethical Naturalism (SEN) and Analytical Descriptivism – seem to conflict with plausible views about cases where moral debate and disagreement is possible. Both lack safeguards to avoid divergence of reference across different communities, which can scupper the prospects for genuine moral disagreement. I explore the prospects for supplementing both views with Lewis's notion of eligibility, arguing that this can solve the problem for a modified form of analytical descriptivism, and (...) for a modified form of SEN too (though perhaps more controversially). I close by considering the appropriateness of using the notions of eligibility and joint-carving in ethics. (shrink)

The standard philosophical project of analysing the concept of knowledge has radical defects in its arbitrary restriction of the subject matter, and its risky theoretical presuppositions. Edward Craig suggests a more illuminating approach, akin to the `state of nature' method found in political theory, which builds up the concept from a hypothesis about the social function of knowledge and the needs it fulfils. Light is thrown on much that philosophers have written about knowledge, about its analysis and the obstacles (...) to its analysis, and on the debate over scepticism. It becomes apparent why many languages not only have such constructions as `knows whether' and `knows that', but also have equivalents of `knows how to' and `know' followed by a direct object. Thus the inquiry is both broadened in scope and made theoretically less fragile. (shrink)

This chapter concentrates on the edges of the lived body, which act to mediate between the outermost and innermost edges. The prospects for construing bodily edges are explored. Bodily edges realise the paradigm of definitive but incomplete self-knowledge in a very particular way: namely, that such edges are parts of parts. The internal and external edges of bodily parts are not only glimpsed in the course of ongoing experience but also offer a grip for hands. Inside/outside is an especially significant (...) binary edge structure, and is altogether central to edges that inhere in bodies. Bodily edges act as the mediatrix between the edges of the perceived earth and those of the inner psyche, and also provide the conjunctures for many things in experienced life-worlds. (shrink)
