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)

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.

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.

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.

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.

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)

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.

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)

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)

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)

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)

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.

The classic theory of Common Law is based on the idea of a law derived from immemorial customs that guide judges’ decisions and contribute to the continuity and stability of the legal order. Hobbes, in his criticism of Edward Coke, questions the legal principles that characterize the “spirit of Common Law”. In his view, it is authority and not use that makes the law. This Hobbesian criticism, which can be considered as one of the ­sources of positivist interpretation (...) of customary law, first raises the question of the legal validity of custom but also leads to an original analysis of the court decisions and precedents. Two forms of rationality of law are opposed: one based on custom and knowledge of which is an “artificial reason”, the other based on natural law and the prescriptions of the judges’ individual reason.

This paper discusses sovereignty and examines in detail Hobbes’s debates with the two leading legal theorists of his day, Coke and Hale, both Lord Chief Justices of the King’s Bench. I argue that Hobbes came to change his mind somewhat about the desirability of divided sovereignty by the time, near the end of his life, that he wrote the Dialogue . But I also argue that Hobbes should have developed more than a very thin conception of the rule of (...) law. Hobbes should have been more open to the ideas that the jurists of his day were developing, especially the idea that the judiciary should have independent status. (shrink)

ABSTRACTI contextualize and interpret the distinction in Hobbes’ Leviathan between the capacities of the sovereign and show its importance for contemporary debates on the nature of Hobbesian sovereignty. Hobbes distinguishes between actions the sovereign does on personal title, and actions he undertakes in a political capacity. I argue that, like royalists defending King Charles I before and during the English civil war, he maintains that the highest magistrate is sovereign in both his natural and political capacities because the capacities are (...) inseparable, though district. This position goes back to the treatment of Calvin’s Case by Francis Bacon and Edward Coke and has further precedents in medieval English constitutional thought. An important reason for Hobbes to include this doctrine in Leviathan, I suggest, is to provide a response to parliamentarians who employed the sovereign’s multiple capacities to justify armed resistance against the king. I show the relevance of this contextualization by intervening in two recent debates, regarding the possibility of constitutionalist limitations on the actions of the Hobbesian sovereign and regarding whether sovereignty is held by the commonwealth or by the person of the sovereign.

This essay builds on recent work by Susan Haack to suggest that Oliver Wendell Holmes Jr.’s conception of the common law was influenced by Darwinian evolution and classical pragmatism. This is no small claim: perceptions of what the common law is and does within the constitutional framework of the United States continue to be heavily debated. Holmes’s paradigm for the common law both revised and extended the models set forth by Sir Edward Coke, Thomas Hobbes, Sir Matthew Hale, (...) and Sir William Blackstone. Adding additional substance to Haack’s argument by pointing out passages in Holmes’s opinions and in his only book, The Common Law, that corroborate her claims about the particular features of Holmes’s pragmatism, this essay concludes by suggesting that, because of his connections with the classical pragmatists and his reverence for Emerson, Holmes is the best place to begin answering the famous question formulated by Stanley Cavell: “What’s the Use in Calling Emerson a Pragmatist?”.

The primary objective of this study is to provide a description of the major ideas about void space within and beyond the world that were formulated between the fourteenth and early eighteenth centuries. The second part of the book - on infinite, extracosmic void space - is of special significance. The significance of Professor Grant's account is twofold: it provides the first comprehensive and detailed description of the scholastic Aristotelian arguments for and against the existence of void space; and it (...) presents (again for the first time) an analysis of the possible influence of scholastic ideas and arguments on the interpretations of space proposed by the nonscholastic authors who made the Scientific Revolution possible. The concluding chapter of the book is unique in not only describing the conceptualizations of space proposed by the makers of the Scientific Revolution, but in assessing the role of readily available scholastic ideas on the conception of space adopted for the Newtonian world.

In the course of his long development, Kant's concept of matter changed somewhat, while his concept of scientific explanation changed considerably. Both developments achieved a coherent integration in Kant's Metaphysical Foundations of Natural Science. Using this developmental background, the present paper argues that the Foundations should be interpreted as an attempted rational reconstruction of the mechanics of Newton and Euler. Kant attempted to do this by constructing a concept of matter that would confer a Leibnizian intelligibility on Newtonian mechanics, and (...) also accord with Kant's theories on the nature of concepts and their role in scientific explanation.

The modal object calculus is the system of logic which houses the (proper) axiomatic theory of abstract objects. The calculus has some rather interesting features in and of itself, independent of the proper theory. The most sophisticated, type-theoretic incarnation of the calculus can be used to analyze the intensional contexts of natural language and so constitutes an intensional logic. However, the simpler second-order version of the calculus couches a theory of fine-grained properties, relations and propositions and serves as a framework (...) for defining situations, possible worlds, stories, and fictional characters, among other things. In the present paper, we focus on the second-order calculus. The second-order modal object calculus is so-called to distinguish it from the second-order modal predicate calculus. Though the differences are slight, the extra expressive power of the object calculus significantly enhances its ability to resolve logical and philosophical concepts and problems. (shrink)

Implicit in the scottish tradition is a metaphilosophy of commonsense which deserves as much attention as that recently given to scottish presentative realism and agent causality. The author articulates this metaphilosophy by (a) sketching a systematic metaphilosophy of commonsense, (b) considering to what extent thomas reid fits this pattern, And (c) deciding to what extent asa mahan, One of the ablest of the american realists, Fits it. The result is a characterization of a coherent scottish metaphilosophy still worthy of consideration. (...) He also explores the question whether the metaphilosophy that emerges from (b) and (c) is part of an ongoing tradition. It has been suggested that there are important similarities between the scottish view and g e moore's concept of analysis. While he agrees that there are analogies he stresses the disanalogies as more enlightening about the nature of both. (shrink)

Many neuroimaging studies of semantic memory have argued that knowledge of an object's perceptual properties are represented in a modality-specific manner. These studies often base their argument on finding activation in the left-hemisphere fusiform gyrus-a region assumed to be involved in perceptual processing-when the participant is verifying verbal statements about objects and properties. In this paper, we report an extension of one of these influential papers-Kan, Barsalou, Solomon, Minor, and Thompson-Schill (2003 )-and present evidence for an amodal component in the (...) representation and processing of perceptual knowledge. Participants were required to verify object-property statements (e.g., "cat-whiskers?"; "bear-wings?") while they were being scanned by functional magnetic resonance imaging (fMRI). We replicated Kan et al.'s activation in the left fusiform gyrus, but also found activation in regions of left inferior frontal gyrus (IFG) and middle-temporal gyrus, areas known to reflect amodal processes or representations. Further, only activations in the left IFG, an amodal area, were correlated with measures of behavioural performance. (shrink)

avant propos This paper is basically Keenan (1992) augmented by some new types of properly polyadic quantification in natural language drawn from Moltmann (1992), Nam (1991) and Srivastav (1990). In addition I would draw the reader's attention to recent mathematical studies of polyadic quantiicationz Ben-Shalom (1992), Spaan (1992) and Westerstahl (1992). The first and third of these extend and generalize (in some cases considerably) the techniques and results in Keenan (1992). Finally I would like to acknowledge the stimulating and constructive (...) discussions ofthe earlier paper with many scholars, notably Dorit Ben-Shalom, Jaap van der Does, Hans Kamp, Uwe Mormich, Arnim von Stechow, Mats Rooth, and Ede Zimmermann. And I repeat here the acknowledgment in the earlier paper to Jim Lambek, Ed Stabler and two anonymous referees for Linguistics and Philosophy (the latter responsible for substantial improvements in the proofs - see footnote 10).

Alexander Herzen was the most outstanding figure in the early period of the Russian revolutionary movement. Lenin claimed him as a forerunner of the Bolsheviks, and Soviet scholars have sought to establish his latent sympathy with Marxism. In the west on the other hand, he has been seen as a precursor of Solzhenitsyn, the personification of protest against all forms of oppression. Dr Acton provides a compelling intellectual biography. The focus is on the years between 1847 and 1863. Herzen's ideas (...) are set in the context of those political developments and dramatic private experiences that affected his outlook. His profound faith in human nature and in the inevitable triumph of socialism was undermined not only by the failure of the revolutions of 1848, but even more deeply by personal catastrophe - the discovery of the infidelity of his beautiful wife Natalie. This dual blow, Dr Acton shows, had a decisive impact upon Herzen's approach to Russian problems. It lay at the root of the ambivalent attitude he adopted towards peasant revolution in the critical period of Emancipation. (shrink)

Willard Van Orman Quine's work revolutionized the fields of epistemology, semantics and ontology. At the heart of his philosophy are several interconnected doctrines: his rejection of conventionalism and of the linguistic doctrine of logical and mathematical truth, his rejection of the analytic/synthetic distinction, his thesis of the indeterminacy of translation and his thesis of the inscrutability of reference. In this book Edward Becker sets out to interpret and explain these doctrines. He offers detailed analyses of the relevant texts, discusses (...) Quine's views on meaning, reference and knowledge, and shows how Quine's views developed over the years. He also proposes a new version of the linguistic doctrine of logical truth, and a new way of rehabilitating analyticity. His rich exploration of Quine's thought will interest all those seeking to understand and evaluate the work of one of the most important philosophers of the second half of the twentieth century.
