This paper approaches the problem of testimony from a new direction. Rather than focusing on the epistemic grounds for testimony, it considers the problem from the perspective of an individual who must choose whom to trust from a population of many would-be testifiers. A computer simulation is presented which illustrates that in many plausible situations, those who trust without attempting to judge the reliability of testifiers outperform those who attempt to seek out the more reliable members of the community. In (...) so doing, it presents a novel defense for the credulist position that argues one should trust testimony without considering the underlying reliability of the testifier. (shrink)

Costly signalling theory has become a common explanation for honest communication when interests conflict. In this paper, we provide an alternative explanation for partially honest communication that does not require significant signal costs. We show that this alternative is at least as plausible as traditional costly signalling, and we suggest a number of experiments that might be used to distinguish the two theories.

Much of contemporary knowledge is generated by groups not single individuals. A natural question to ask is, what features make groups better or worse at generating knowledge? This paper surveys research that spans several disciplines which focuses on one aspect of epistemic communities: the way they communicate internally. This research has revealed that a wide number of different communication structures are best, but what is best in a given situation depends on particular details of the problem being confronted by the (...) group.

In seeking to explain the evolution of social cooperation, many scholars are using increasingly complex game-theoretic models. These complexities often model readily observable features of human and animal populations. In the case of previous games analyzed in the literature, these modifications have had radical effects on the stability and efficiency properties of the models. We will analyze the effect of adding spatial structure to two communication games: the Lewis Sender-Receiver game and a modified Stag Hunt game. For the Stag Hunt, (...) we find that the results depart strikingly from previous models. In all cases, the departures increase the explanatory value of the models for social phenomena. (shrink)

It is widely believed that bringing parties with differing opinions together to discuss their differences will help both in securing consensus and also in ensuring that this consensus closely approximates the truth. This paper investigates this presumption using two mathematical and computer simulation models. Ultimately, these models show that increased contact can be useful in securing both consensus and truth, but it is not always beneficial in this way. This suggests one should not, without qualification, support policies which increase interpersonal (...) contact if one seeks to improve the epistemic performance of groups. (shrink)

Ecological psychologists and enactivists agree that the best explanation for a large share of cognition is nonrepresentational in kind. In both ecological psychology and enactivist philosophy, then, the task is to offer an explanans that does not rely on representations. Different theorists within these camps have contrasting notions of what the best kind of nonrepresentational explanation will look like, yet they agree on one central point: instead of focusing solely on factors interior to an agent, an important aspect of cognition (...) is found in the link or coupling between an agent and the external world. This link is fluid, dynamic, and active in a variety of ways, and we do not need to add any internal extra something in the perception-action-cognition process. At the same time, even devout defenders of ecological psychology and enactivism recognize that plenty happens inside an agent during cognition. In particular, no one denies that the brain plays an important role. What, then, is the role of the brain if it’s not in the game of representing the environment? One possible option is to describe the brain as a resonant organ instead of a representational organ. In this paper we consider the history of resonance in more detail. Particular focus will be placed on two different sets of approaches that have developed the concept of resonance: a representational reading of resonance and a nonrepresentational, dynamic account of resonance. We then apply these accounts to a case study on music performance, specifically in the context of standard tonal jazz. From this application, we propose that a nonrepresentational resonance account consistent with both enactivism and ecological psychology is a viable way of explaining jazz performance. We conclude with future considerations on research regarding the brain as a resonant organ. (shrink)

Traditionally, epistemologists have distinguished between epistemic and pragmatic goals. In so doing, they presume that much of game theory is irrelevant to epistemic enterprises. I will show that this is a mistake. Even if we restrict attention to purely epistemic motivations, members of epistemic groups will face a multitude of strategic choices. I illustrate several contexts where individuals who are concerned solely with the discovery of truth will nonetheless face difficult game theoretic problems. Examples of purely epistemic coordination problems and (...) social dilemmas will be presented. These show that there is a far deeper connection between economics and epistemology than previous appreciated. (shrink)

We model the impact of different incentives on journal behavior in undertaking peer review. Under one scheme, the journal aims to publish the highest-quality papers; under the second, the journal aims to maintain a high rejection rate. Under both schemes, journals prefer to set very high standards for acceptance despite allowing significant error in peer review. Under the second scheme, however, in order to encourage more submissions of mediocre papers, the journal is incentivized to make its editorial process less accurate. (...) This leads to both worse peer review and lower-quality articles being published. (shrink)

Theories of scientific rationality typically pertain to belief. In this paper, the author argues that we should expand our focus to include motivations as well as belief. An economic model is used to evaluate whether science is best served by scientists motivated only by truth, only by credit, or by both truth and credit. In many, but not all, situations, scientists motivated by both truth and credit should be judged as the most rational scientists.

This article presents the evolutionary dynamics of three games: the Nash bargaining game, the ultimatum game, and a hybrid of the two. One might expect that the probability that some behavior evolves in an environment with two games would be near the probability that the same behavior evolves in either game alone. This is not the case for the ultimatum and Nash bargaining games. Fair behavior is more likely to evolve in a combined game than in either game taken individually. (...) This result confirms a conjecture that the complexity of our actual environment provides an explanation for the evolution of fair behavior. Key Words: evolutionary game theory • Nash bargaining game • ultimatum game • fairness. (shrink)

Sports such as surfing, mountaineering, and backcountry skiing are often grouped together. But what exactly it is that they share, and the implications of their common characteristics, have not been explained clearly. I refer to such sports as ‘nature sports’ and argue that they share a fundamental structure in which human beings and features of the natural world are brought together. The principal claim I make is that nature sports are those sports in which a particular natural feature, or combination (...) of natural features, plays at least one of the primary roles that human competitors or partners play in traditional or standard sports. This article is a detailed explanation of that claim. (shrink)

John Searle's The Rediscovery of the Min is a sustained attempt to locate the mind and the mental firmly in the realm of the physical. Consciousness ,claims Searle, is just an ordinary biological feature of the world ... More specifically,``[t]he mental state of consciousness is just an ordinary biological, that is, physical featureof the brain''. Searle is adamant: ``Consciousness,to repeat, is a natural biological phenomenon''.

One of the most interesting challenges facing paleobiologists is explaining the Cambrian explosion, the dramatic appearance of most metazoan animal phyla in the Early Cambrian, and the subsequent stability of these body plans over the ensuing 530 million years. We propose that because phenotypic variation decreases through geologic time, because microRNAs (miRNAs) increase genic precision, by turning an imprecise number of mRNA transcripts into a more precise number of protein molecules, and because miRNAs are continuously being added to metazoan genomes (...) through geologic time, miRNAs might be instrumental in the canalization of development. Further, miRNAs ultimately allow for natural selection to elaborate morphological complexity, because by reducing gene expression variability, miRNAs increase heritability, allowing selection to change characters more effectively. Hence, miRNAs might play an important role in shaping metazoan macroevolution, and might be part of the solution to the Cambrian conundrum. (shrink)

Many scientific theories purport to describe empirically inaccessible aspects of the world. The agenda of foundational physics is more ambitious still: to characterize the world at the level of 'primitive ontology'. In this pursuit it often posits new and peculiar physical features, a proclivity aided by the abstract, mathematical way in which foundational theories are framed. But how do we decipher their physical content, and in particular the accounts of primitive ontology they offer, and why think that content is true? (...) This dissertation explores the relationship between these questions -- between the problem of ontological interpretation in foundational physics and the nature of scientific realism. I do not argue for a unified account. Rather, I examine three contexts in which their interactions are particularly interesting and philosophically significant. First, I consider the role scientific methodology plays in a prominent naturalistic defense of scientific realism: the no-miracles argument. The most sophisticated form of this argument rests on the broad claim that successful scientific methodology is irredeemably theory dependent. I examine the nature of this theory dependence within the context of Maxwell's development of electromagnetism, and argue that the presence of competing ontological interpretations undermines the realist's attempt to draw sweeping epistemic conclusions from methodological success. I next consider the concept of theoretical reformulation and how it applies to the claim that Lagrangian dynamics is a reformulation of (part of) Newtonian dynamics. How should this claim be understood in light of the fact that the world is non-classical? What can this tell us about the concept of theory reformulation itself, which plays a central role in arguments against scientific realism? I provide an analysis of theory reformulation in terms of counterfactual interpretative judgments, and then cast doubt on its justification in the classical case by developing a non-Newtonian interpretation of Lagrangian dynamics. Finally, I consider whether competing ontological interpretations raise underdetermination problems for realism about foundational physics. After first re-formulating the underdetermination argument to avoid recent objections that it fails to pose any distinctive threat, I suggest a formulation of realism that vitiates the underdetermination threats posed by competing ontological interpretations.

A truly inclusive democratic politics must be understandable, or cognitively tractable, for ordinary people busy with the rest of their lives. This extends not only to everyday politics and policy, but to constitutional politics as well—non-specialist democratic citizens should be able to grasp the fundamental law that governs them and imagine their own role in shaping it as political agents. Yet these requirements raise a difficulty: in many countries, including the United States, constitutions are treated as the exclusive domain of (...) lawyers and judges. As a result, constitutional matters are typically discussed using legalistic jargon that is inscrutable even to non-specialist lawyers, let alone ordinary citizens. How then can constitutional politics be made legible to ordinary citizens? In this essay, I argue this challenge is partly one of political ideas—specifically, the ideas ordinary citizens use to think about their constitutions, or their folk constitutionalism. This may sound strange because insofar as constitutions are treated as lawyers’ exclusive turf, the problem may seem to be one of practice, not merely ideas. But popular practices of what scholars like John Finn and Elizabeth Beaumont call popular or civic constitutionalism involve citizens and social movements in transforming constitutions. These transformations often occur behind the backs of everyone involved, as new frames and understandings come to gradually transmute constitutional meaning, which in turn pervades the public political culture and reshapes the public’s constitutional imagination. I suggest we need ideas that more closely reflect what democratic citizens already do in democratic constitutional politics, so that they can do it more self-consciously and dispel the impression of an anti-democratic lack of control that recent constitutional innovations reveal to be illusory. I explore the utility of ideas of unwrittenness and functional multi-textuality to the end of a folk constitutionalism appropriate for democracy. (shrink)

Increasingly, epistemologists are becoming interested in social structures and their effect on epistemic enterprises, but little attention has been paid to the proper distribution of experimental results among scientists. This paper will analyze a model first suggested by two economists, which nicely captures one type of learning situation faced by scientists. The results of a computer simulation study of this model provide two interesting conclusions. First, in some contexts, a community of scientists is, as a whole, more reliable when its (...) members are less aware of their colleagues' experimental results. Second, there is a robust tradeoff between the reliability of a community and the speed with which it reaches a correct conclusion. ‡The author would like to thank Brian Skyrms, Kyle Stanford, Jeffrey Barrett, Bruce Glymour, and the participants in the Social Dynamics Seminar at University of California–Irvine for their helpful comments.

Postmodernity allows for no absolutes and no essence. Yet theology is concerned with the absolute, the essential. How then does theology sit within postmodernity? Is postmodern theology possible, or is such a concept a contradiction in terms? Should theology bother about postmodernism or just get on with its own thing? Can it? Theologians have responded in many different ways to the challenges posed by theories of postmodernity. In this introductory 2003 guide to a complex area, editor Kevin J. Vanhoozer (...) addresses the issue head on in a lively survey of what 'talk about God' might mean in a postmodern age, and vice versa. The book then offers examples of different types of contemporary theology in relation to postmodernity, while the second part examines the key Christian doctrines in postmodern perspective. Leading theologians contribute to this clear and informative Companion, which no student of theology should be without. (shrink)

ABSTRACTA recent line of argument insists that replacing democracy with markets would improve social decision making due to markets’ superior use of knowledge. These arguments are flawed by unrealistic assumptions, unfair comparisons, and a neglect of the epistemic limits of markets. In reality, the epistemic advantages of markets over democracy are circumscribed and often illusory. A recognition of markets’ epistemic limits can, however, provide guidance for designing institutions in ways that capture the advantages of both.

Journals regulate a significant portion of the communication between scientists. This paper devises an agent-based model of scientific practice and uses it to compare various strategies for selecting publications by journals. Surprisingly, it appears that the best selection method for journals is to publish relatively few papers and to select those papers it publishes at random from the available “above threshold” papers it receives. This strategy is most effective at maintaining an appropriate type of diversity that is needed to solve (...) a particular type of scientific problem. This problem and the limitation of the model is discussed in detail. (shrink)

Mental capacities for perceiving, remembering, thinking, and planning involve the processing of structured mental representations. A compositional semantics of such representations would explain how the content of any given representation is determined by the contents of its constituents and their mode of combination. While many have argued that semantic theories of mental representations would have broad value for understanding the mind, there have been few attempts to develop such theories in a systematic and empirically constrained way. This paper contributes to (...) that end by developing a semantics for a ‘fragment’ of our mental representational system: the visual system’s representations of the bounding contours of objects. At least three distinct kinds of composition are involved in such representations: ‘concatenation’, ‘feature composition’, and ‘contour composition’. I sketch the constraints on and semantics of each of these. This account has three principal payoffs. First, it models a working framework for compositionally ascribing structure and content to perceptual representations, while highlighting core kinds of evidence that bear on such ascriptions. Second, it shows how a compositional semantics of perception can be compatible with holistic, or Gestalt, phenomena, which are often taken to show that the whole percept is ‘other than the sum of its parts’. Finally, the account illuminates the format of a key type of perceptual representation, bringing out the ways in which contour representations exhibit domain-specific form of the sort that is typical of structured icons such as diagrams and maps, in contrast to typical discursive representations of logic and language.

Accumulating evidence suggests that different magnitudes (e.g., number, size, and duration) are spatialized in the mind according to a common left–right metric, consistent with a generalized system for representing magnitude. A previous study conducted by two of us (Holmes & Lourenco, ) provided evidence that this metric extends to the processing of emotional magnitude, or the intensity of emotion expressed in faces. Recently, however, Pitt and Casasanto () showed that the earlier effects may have been driven by a left–right mapping (...) of mouth size rather than emotional magnitude, and they found no evidence for an emotional magnitude mapping when using words as stimuli. Here, we report two new experiments that further examine these conclusions. In Experiment 1, using face stimuli with mouths occluded, we replicate the original finding: Less emotional faces were associated with the left and more emotional faces with the right. However, we also find that people can reliably infer the sizes of the occluded mouths, and that these inferred mouth sizes can explain the observed left–right mapping. In Experiment 2, we show that comparative judgments of emotional words yield a left–right mapping of emotional magnitude not attributable to stimulus confounds. Based on these findings, we concur with Pitt and Casasanto that faces pose challenges for isolating the forces driving spatialization, but we suggest that emotional magnitude, when assessed using unconfounded stimuli in a sufficiently sensitive task, may indeed be spatialized as originally proposed. Suggestions for further research on the spatialization of emotional magnitude are discussed. (shrink)

This article argues that a phenomenological notion of “lived body” emerges in the Zhuangzi’s 莊子 critique of the Confucian body of ritual and morality. It also argues that a philosophical account of body cannot be reduced to a Sinological account. This article draws on the phenomenological distinction between “object body” and “lived body,” especially the “three ontological dimensions” of Jean-Paul Sartre to argue that the Zhuangzi criticizes the Confucian body of ritual and morality as being a “body-for-others” and that it (...) maintains a concept of “lived body.” Finally, it argues that through such methods of cultivation as “sitting and forgetting” a liberation of the body is achieved where one is connected to dao 道 and achieves a state of heightened experience.

ABSTRACT The story of the butcher Pao Ding is one of the best known from the Zhuangzi 莊子. The key concept in this story is yangsheng 養生. This has been understood as involving the preservation of life through various methods of cultivation. However, one insightful perspective has yet to be considered: work. This article sets the stage for understanding yangsheng in terms of work by appealing to Western and Eastern understandings thereof. It then locates the Zhuangzi in contemporary discourse on (...) yangsheng showing that it rejects that concerned with regulating the senses in search of life and accepts that concerned with the activities constitutive of livelihoods. This article then analyzes the relationship between sheng 生 and xing 性 to show that yangsheng is best understood as ‘making a living’ that emerges in the process of individual and collective lives as they unfold in various contexts.

What does it take to be a good democratic citizen? Many scholars emphasize that being a good citizen is difficult because there is so much citizens should know to participate responsibly in politics. These critics implicitly assume that citizens should aspire to be “omnicompetent citizens:” fully informed about the issues of the day, candidates’ stances on them, and relevant scientific knowledge. In this article, I advance an alternative, less demanding standard of good citizenship in which citizens focus their political concern (...) on just a few issues, or even a single one. I defend this model of specialized citizenship from the objection that it licenses myopic and irresponsible decision making by citizens with two complementary arguments. The first draws from the work of Bernard Williams to demonstrate the ethical permissibility of citizens making decisions based on even single issues when they implicate citizens’ fundamental commitments. The second argument suggests that such seemingly blinkered decision-making may, when operating systemically, improve democratic decision making via a division of labor between citizens specializing in different issues. I conclude that there may be less of a tension between the demands of ordinary life and those of a flourishing democracy than previously thought. (shrink)

An evolutionary case for the existence of free will. Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency-or free will-is an illusion. In Free Agents, leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose. (...) Traversing billions of years of evolution, Mitchell tells the remarkable story of how living beings capable of choice emerged from lifeless matter. He explains how the emergence of nervous systems provided a means to learn about the world, granting sentient animals the capacity to model, predict, and simulate. Mitchell reveals how these faculties reached their peak in humans with our abilities to imagine and to introspect, to reason in the moment, and to shape our possible futures through the exercise of our individual agency. Mitchell's argument has important implications-for how we understand decision making, for how our individual agency can be enhanced or infringed, for how we think about collective agency in the face of global crises, and for how we consider the limitations and future of artificial intelligence.An astonishing journey of discovery, Free Agents offers a new framework for understanding how, across a billion years of Earth history, life evolved the power to choose and why this matters.

There is growing interest in understanding and eliciting division of labor within groups of scientists. This paper illustrates the need for this division of labor through a historical example, and a formal model is presented to better analyze situations of this type. Analysis of this model reveals that a division of labor can be maintained in two different ways: by limiting information or by endowing the scientists with extreme beliefs. If both features are present however, cognitive diversity is maintained indefinitely, (...) and as a result agents fail to converge to the truth. Beyond the mechanisms for creating diversity suggested here, this shows that the real epistemic goal is not diversity but transient diversity. (shrink)

Perception is a central means by which we come to represent and be aware of particulars in the world. I argue that an adequate account of perception must distinguish between what one perceives and what one's perceptual experience is of or about. Through capacities for visual completion, one can be visually aware of particular parts of a scene that one nevertheless does not see. Seeing corresponds to a basic, but not exhaustive, way in which one can be visually aware of (...) an item. I discuss how the relation between seeing and visual awareness should be explicated within a representational account of the mind. Visual awareness of an item involves a primitive kind of reference: one is visually aware of an item when one's visual perceptual state succeeds in referring to that particular item and functions to represent it accurately. Seeing, by contrast, requires more than successful visual reference. Seeing depends additionally on meta-semantic facts about how visual reference happens to be fixed. The notions of seeing and of visual reference are both indispensable to an account of perception, but they are to be characterized at different levels of representational explanation. (shrink)

Abstract:Qi has been both understood separately as substance and as field. This essay argues that qi in the Zhuangzi is both substance and field together. This qi field-substance is bidimensional where its vertical axis is that of substance and its horizontal axis that of field. This essay argues that the vertical dimension does not imply a substance dualism but a holism where qi differs in degrees of refinement; it argues that the horizontal dimension is composed of interrelated yinyang forces that (...) constitute an "empty" field. It also argues that at the center of this qi field-substance is the heart-mind and the body and, by drawing on rich resonances between the Zhuangzi and phenomenology, that human beings bring the fields of qi that they are situated in into certain coherences.

This paper delineates the thrust of Augustine's theodicy against the broader background of his Christian Neoplatonic outlook. We examine Augustine's initial Manichean influences and see how these beliefs carry over to his mature thought, which is evident in the seventh book of the Confessions. After Augustine's time with the Manicheans, we look at how he was so influenced by the books of the Platonists (libri platonicorum). Although Augustine's position regarding the problem of evil shifts, his idea of the primacy of (...) the soul is still evident in his thought process. To wit, Augustine posits that evil must be considered a privation of the Good, so much so as to reach the point of complete nonentity. Human beings' ability to be corrupted by evils rests in their position as being created ex-nihilo by God. With this creation also comes an inherent mutability. Due to human mutability, Augustine believes that God is not responsible for such evil actions. This paper also contrasts this belief with modern empiricist David Hume's idea regarding God's responsibility for human actions. Hume argues that the volition of all human actions rests in God as Creator of the world. As creator, Hume claims that God places human beings in a position to act. If humans are predisposed to perform evil actions, they cannot be faulted. Augustine would counter that argument by claiming that evil is not a substance. Not being a substance, evil is there not ascribable to God. Ultimately, Augustine's theodicy is based upon the goodness of God. (shrink)

T'Challa, seemingly risen from the dead after having suffered grievous wounds and a fall from a high cliff, openly challenges Erik Killmonger's right to be called King of Wakanda. With T'Challa's return, Killmonger orders W'Kabi to "kill this clown," but Okoye decides to follow tradition, not Killmonger, saying to her husband W'Kabi that "the challenge is not complete." The same principle is at work when, earlier in the film, T'Challa engages in ritual combat against M'Baku, leader of the Jabari Tribe. (...) T'Challa, occupying the most privileged position, can smile bemusedly and shake his head at Shuri's outburst, and a child in the crowd can innocently slap his hand to his forehead in disbelief; but the adults present are not amused at Shuri's transgressions. Shuri may be the most visible gadfly, but the harshest – and, ultimately, most effective – critics of Wakanda's kings are Killmonger, Nakia, and T'Challa himself. (shrink)

In this multi-faceted volume, Christian and other religiously committed theorists find themselves at an uneasy point in history—between premodernity, modernity, and postmodernity—where disciplines and methods, cultural and linguistic traditions, and religious commitments tangle and cross. Here, leading theorists explore the state of the art of the contemporary hermeneutical terrain. As they address the work of Gadamer, Ricoeur, and Derrida, the essays collected in this wide-ranging work engage key themes in philosophical hermeneutics, hermeneutics and religion, hermeneutics and the other arts, hermeneutics (...) and literature, and hermeneutics and ethics. Readers will find lively exchanges and reflections that meet the intellectual and philosophical challenges posed by hermeneutics at the crossroads. Contributors are Bruce Ellis Benson, Christina Bieber Lake, John D. Caputo, Eduardo J. Echeverria, Benne Faber, Norman Lillegard, Roger Lundin, Brian McCrea, James K. A. Smith, Michael VanderWeele, Kevin Vanhoozer, and Nicholas Wolterstorff. (shrink)

Stochastic developmental variation is an additional important source of variance – beyond genes and environment – that should be included in considering how our innate psychological predispositions may interact with environment and experience, in a culture-dependent manner, to ultimately shape patterns of human behaviour.

C. S. Lewis called for spiritual formation long before the term became popular: “Every Christian is to become a little Christ. The whole purpose of becoming a Christian is simply nothing else”. Lewis's call to become little Christs recalls Paul's exhortation to “put off” the old self and “put on” Christ. This paper explores what this change of costume involves from the perspective of what a “theodramatic” approach to theology that I have developed in The Drama of Doctrine and Faith (...) Speaking Understanding. I there argue that the role of doctrine is to indicate what is in Christ and direct those in Christ to participate in Christ by playing their parts in the drama of redemption. This theatrical model raises an important issue concerning the disciple's self-understanding: Is it healthy for Christians to think in terms of “acting out” what is “in Christ” or does this encourage a false sense of self – a “put on”? I respond to this question in four steps where I present a theodramatic anthropology, describe discipleship as the project of growing into/putting on Christ, consider three objections to my previous work about the relationship between persons/roles and role-playing, and respond to the objections by offering a dogmatic description of putting on Christ in soteriological, pneumatological, and eschatological terms.
