Perception involves the processing of content or information about the world. In what form is this content represented? I argue that perception is widely compositional. The perceptual system represents many stimulus features (including shape, orientation, and motion) in terms of combinations of other features (such as shape parts, slant and tilt, common and residual motion vectors). But compositionality can take a variety of forms. The ways in which perceptual representations compose are markedly different from the ways in which sentences or (...) thoughts are thought to be composed. I suggest that the thesis that perception is compositional is not itself a concrete hypothesis with specific predictions; rather it affords a productive framework for developing and evaluating specific empirical hypotheses about the form and content of perceptual representations. The question is not just whether perception is compositional, but how. Answering this latter question can provide fundamental insights into perception. (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.

You can perceive things, in many respects, as they really are. For example, you can correctly see a coin as circular from most angles. Nonetheless, your perception of the world is perspectival. The coin looks different when slanted than when head-on, and there is some respect in which the slanted coin looks similar to a head-on ellipse. Many hold that perception is perspectival because you perceive certain properties that correspond to the “looks” of things. I argue that this view is (...) misguided. I consider the two standard versions of this view. What I call the PLURALIST APPROACH fails to give a unified account of the perspectival character of perception, while what I call the PERSPECTIVAL PROPERTIES APPROACH violates central commitments of contemporary psychology. I propose instead that perception is perspectival because of the way perceptual states are structured from their parts. (shrink)

Is voting a duty of democratic citizenship? This article advances a new argument for the existence of a duty to vote. It argues that every normative account of electoral representation requires universal turnout to function in line with its own internal normative logic. This generates a special obligation for citizens to vote in electoral representative contexts as a function of the role morality of democratic citizenship. Because voting uniquely authorizes office holding in representative democracies, and because universal turnout contributes powerfully (...) to representation being fair, to be a good citizen of such democracies requires one to vote. Whereas previous arguments for a duty to vote have invoked basic moral principles like fairness or a Samaritan duty of rescue, this account is based on citizens occupying a vital functional role within electoral representative institutions. This institutional duty solves the “specificity problem” of justifying a duty to vote better than competing accounts and also immunizes the duty to objections that there is no duty to vote when there are only bad choices and that there is a no duty to vote but rather duty to vote well. By emphasizing the tight connection between institutions and individual conduct, the role morality approach used here supplies a less abstract and more realistic framework than much previous research on the ethics of democratic citizenship and brings the debate closer to constitutive features of democratic politics.

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)

Drawing on conceptual works by Murphy (1999) and Solomon (1999), we develop a virtue ethics scale. Other ethics scales, which are grounded in deontological and teleological principles, may be used to classify people according to their beliefs about (1) the criteria they use to make ethical decisions, or (2) the ethicality of those decisions. We suggest augmenting these scales with our virtue ethics scale, which may be used to classify people according to their beliefs about the virtuous qualities of businesspeople.

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.

An ongoing philosophical discussion concerns how various types of mental states fall within broad representational genera—for example, whether perceptual states are “iconic” or “sentential,” “analog” or “digital,” and so on. Here, I examine the grounds for making much more specific claims about how mental states are structured from constituent parts. For example, the state I am in when I perceive the shape of a mountain ridge may have as constituent parts my representations of the shapes of each peak and saddle (...) of the ridge. More specific structural claims of this sort are a guide to how mental states fall within broader representational kinds. Moreover, these claims have significant implications of their own about semantic, functional, and epistemic features of our mental lives. But what are the conditions on a mental state's having one type of constituent structure rather than another? Drawing on explanatory strategies in vision science, I argue that, other things being equal, the constituent structure of a mental state determines what I call its distributional properties—namely, how mental states of that type can, cannot, or must co‐occur with other mental states in a given system. Distributional properties depend critically on and are informative about the underlying structures of mental states, they abstract in important ways from aspects of how mental states are processed, and they can yield significant insights into the variegation of psychological capacities.

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.

It is commonly assumed that images, whether in the world or in the head, do not have a privileged analysis into constituent parts. They are thought to lack the sort of syntactic structure necessary for representing complex contents and entering into sophisticated patterns of inference. I reject this assumption. “Image grammars” are models in computer vision that articulate systematic principles governing the form and content of images. These models are empirically credible and can be construed as literal grammars for images. (...) Images can have rich syntactic structure, though of a markedly different form than sentences in language. (shrink)

Fraud and misleading research represent serious impediments to scientific progress. We must uncover the causes of fraud in order to understand how science functions and in order to develop strategies for combating epistemically detrimental behavior. This paper investigates how the incentive to commit fraud is enhanced by the structure of the scientific reward system. Science is an "accumulation process:" success begets resources which begets more success. Through a simplified mathematical model, I argue that this cyclic relationship enhances the appeal of (...) fraud and makes combating it extremely difficult. (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.

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.

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.

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)

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 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)

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)

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)

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)

Gordon Kaufman is a theologian who wrestles with essential theological issues.

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)

The rise of modern science and the proclaimed 'death' of God in the nineteenth century led to a radical questioning of divine action and authorship - Bultmann's celebrated 'demythologizing'. Remythologizing Theology moves in another direction that begins by taking seriously the biblical accounts of God's speaking. It establishes divine communicative action as the formal and material principle of theology, and suggests that interpersonal dialogue, rather than impersonal causality, is the keystone of God's relationship with the world. This original contribution to (...) the theology of divine action and authorship develops a new vision of Christian theism. It also revisits several long-standing controversies such as the relations of God's sovereignty to human freedom, time to eternity, and suffering to love. Groundbreaking and thought-provoking, it brings theology into fruitful dialogue with philosophy, literary theory, and biblical studies"--Provided by publisher. (shrink)

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)

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)

ABSTRACT Jeffrey Friedman’s Power Without Knowledge provides not only a critique of technocracy but a compelling story about the intimate relationship between three of today’s most important political phenomena: populism, technocracy, and democracy. In contrast to many recent accounts that treat populism as a backlash against technocracy, Friedman’s theory suggests that populism is a lineal descendent of technocracy, with which it shares substantial intellectual DNA. Friedman’s implicit theory of populism helps to explain many of its core features, including its political (...) stances, emotionality, and hostility to mediating institutions, in interpretively charitable ways. Central to Friedman’s analysis is the importance of political epistemology, which supplies key connective tissue between the three phenomena. The relations between technocracy, democracy, and populism revealed by Friedman’s theory generate both enlightening and disturbing implications for democratic theory. (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.

This article considers the implications of inferentialist philosophy of language for debates in the historiography of philosophy. My intention is to mediate and refine the polemics between contextualist historians and ‘analytic’ or presentist historians. I claim that much of Robert Brandom’s nuanced defence of presentism can be accepted and even adopted by contextualists, so that inferentialism turns out to provide an important justification for orthodox history of philosophy. In the concluding sections I argue that the application of Brandom’s theory has (...) important limits, and that some polemics by contextualists against presentists are therefore justified. (shrink)

Feminist theorist and educator, bell hooks, asserts that to seek true liberation one must choose marginality. One must choose to occupy the space outside the binary between colonizer-colonized, hegemonic center-periphery, and us-them in order to create a location of possibility. This essay will reveal the practice of social justice as the navigation of the space that difference makes and argue that choosing marginality provides a framework for health humanities work towards social justice in health care. The space of the launderette (...) that is depicted in Hanif Kureishi’s 1986 film, My Beautiful Laundrette, provides an example of choosing marginality and illustrates how difference structures both real and imagined spaces, which influences how individuals ultimately perceive one another. We will draw from the work of bell hooks; political geographer, Edward Soja; and Marxist philosopher, Henri Lefebvre, to demonstrate the importance of the health humanities’ position at the margin to traditional health care education. -/- .

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)

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.

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 order to make strategic decisions and improve their firm’s performance, top management teams must have information on the competitive context in general, and the firm’s competitors in particular. During the decision-making process, top managers can have access to “privileged information”—i.e., information of a confidential and potentially strategic nature that could ultimately confer a decisional advantage over competing parties. However, obtaining and using privileged information in a business context is often illegal—and if not, is usually deemed unethical or “against the (...) rules.” Using a quasi-experimental design, this study explores the reasons why an individual might engage in such unethical behavior. We assess the extent to which managers use privileged information with respect to perceived team cohesion and peers’ ethicality. More specifically, our results show that the use of privileged information is predicted by the decision-maker’s perceptions of their team cohesion and their peers’ ethicality. Moreover, we find that team performance, as a group-level nonself-reported factor, moderates the relationship between cohesion and the use of privileged information. The relationship between cohesion, ethical behavior, and team performance is also discussed. We draw on these findings to make some practical suggestions on how to incorporate practices that could better prevent the unethical use of privileged information in strategic decision-making processes.
