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)

The present paper concerns the motivational underpinnings and behavioral correlates of the prevention or stopping of negative stimulation – a situation referred to as relief. Relief is of great theoretical and applied interest. Theoretically, it is tied to theories linking affect, emotion, and motivational systems. Importantly, these theories make different predictions regarding the association between relief and motivational systems. Moreover, relief is a prototypical antecedent of counterfactual emotions, which involve specific cognitive processes compared to factual or mere anticipatory emotions. Practically, (...) relief may be an important motivator of addictive and phobic behaviors, self destructive behaviors, and social influence. In the present paper, we will first provide a review of conflicting conceptualizations of relief. We will then present an integrative relief model (IRMO) that aims at resolving existing theoretical conflicts. We then review evidence relevant to distinctive predictions regarding the moderating role of various procedural features of relief situations. We conclude that our integrated model results in a better understanding of existing evidence on the affective and motivational underpinnings of relief, but that further evidence is needed to come to a more comprehensive evaluation of the viability of IRMO.

The handicap principle has come under significant challenge both from empirical studies and from theoretical work. As a result, a number of alternative explanations for honest signaling have been proposed. This paper compares the evolutionary plausibility of one such alternative, the "hybrid equilibrium," to the handicap principle. We utilize computer simulations to compare these two theories as they are instantiated in Maynard Smith's Sir Philip Sidney game. We conclude that, when both types of communication are possible, evolution is unlikely (...) to lead to handicap signaling and is far more likely to result in the partially honest signaling predicted by hybrid equilibrium theory.

White climate ethicists have a responsibility to learn, teach, and write about the intersections between climate change and white supremacy. Learning from Andrea Smith’s understanding of white supremacy as three pillars—commodification, orientalism, and genocide—built from heteropatriarchy, this essay argues that white climate ethicists should focus on particular experiences rather than universal narratives; learn from histories of colonization, slavery, and genocide; and support coalitions that empower people of color and indigenous communities. A focus on the writings of scholars from marginalized (...) identities leads to an understanding of climate change as atmospheric defilement. (shrink)

In this paper we show that there are certain limits as to what applications of Maynard Smith’s concept of evolutionarily stable strategy can tell us about evolutionary processes. We shall argue that ESS is very similar in spirit to a particular branch of rational choice game theory, namely, the literature on refinements of Nash equilibrium. In the first place, ESS can also be viewed as a Nash equilibrium refinement. At a deeper level, ESS shares a common structure with other (...) rational choice equilibrium refinements. An equilibrium is evaluated according to whether it persists under specific kinds of perturbations. In the case of ESS, these perturbations are mutations. However, from a dynamical point of view, focusing exclusively on perturbations of equilibria provides only a partial account of the system under consideration. We will show that this has important consequences when it comes to analyzing game-theoretic models of evolutionary processes. In particular, there are non-ESS states which are significant for evolutionary dynamics. (shrink)

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

The ever‐increasing demand for organs led Spain, France, and other European countries to promote uncontrolled donation after circulatory determination of death (uDCDD). For the same reason, New York City has recently developed its own uDCDD protocol, which differs from European programs in some key ways. The New York protocol incorporates a series of technical and management improvements that address some practical problems identified in response to European uDCDD protocols. However, the more fundamental issue of whether uDCDD donors are dead when (...) organs are procured remains problematic for the New York City protocol and, indeed, for all uDCDD protocols. In the United States, two amendments to the legal criteria of death have been suggested to avoid a formal violation of the dead donor rule in DCDD protocols: first, replacing the requirement “irreversible” with the weaker term “permanent,” and second, using the term “circulatory” instead of “cardiac” to identify the key function that must be lost to declare death. While intended to facilitate controlled DCDD, these modifications create a problem for uDCDD protocols: if extracorporeal membrane oxygenation is introduced to preserve the organs, then circulation is restored after death is declared. In this issue of the Hastings Center Report, Kevin Munjal and colleagues call for a new ethical construct and policy so that uncontrolled and controlled DCDD can coexist. (shrink)

In accord with common usage we understand that the term "ecology" (from the Greek oikos, "home") refers to our being at home on the earth, and "ecological crisis" refers to the destruction that has been worked to make the earth/home less inhabitable for a variety of species. "Creation" refers to the whole created world and all living beings as gifts from God the creator. "Environment" refers to the life context in which we live, our habitat as given to us by God and for which we are responsible. 301 302 KEVIN W. IRWIN mental deterioration and devastation.2 That Roman Catholicism has an important contribution to make to this issue3 is clear from recent magisterial statements as well as from the theological literature under review here. For example, in 1990 John Paul II articulated a number of avenues from within the Catholic tradition that relate to the ecological crisis and the Church's corporate responsibility to face it theologically, spiritually, and practically.4 In 1991 the U.S. bishops issued a more focused document, Renewing the Earth, which was drawn largely from the Church's social teaching tradition.5 The purpose of this article is to review some recent Roman Catholic theological literature in English (originally or recently translated) on environmental theology and ethics that can be understood as deep ecology from within mainstream Catholic thought. The contention of these authors is that the ecological crisis is a matter of theology, ethics, and values. Not surprisingly, given the comparative infancy of Catholicism's theological contribution to this issue, these works include collections of essays with a variety of approaches of varying quality, monographs that deal with the issue with greater methodological pre2 "Intuition, Intrinsic Value, and Deep Ecology," The Ecologist 14 (Sept./Oct., 1984): 56 ; also see Devall Bill and George Sessions, Deep Ecology (Layton, Utah: Gibbs Smith, 1985). 3 It is important to note that other Christian faith traditions have offered pertinent and challenging statements on this issue, especially the Orthodox. See, for example, the statement by Patriarch Dimitrios, Orthodoxy and the Ecological Crisis (Geneva: Ecumenical Patriarchate, 1990). 4 See "Peace with God the Creator, Peace with All of Creation," Origins 19 (Dec. 14, 1989): 465-68. This is but one example of John Paul's voice on this issue, which is not univocal.

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.

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.

Madigan Philosophy / St. John Fisher College Rochester, ny 14618, usa [email protected] One of the most quoted phrases in current popular culture is “six degrees of separation”. It expresses the idea that any human being is connected with any other human being by a chain of at most six acquaintances.1 While there is much debate as to whether this is literally true, it is an interesting thoughtexperiment, as well as the basis for many fun parlour games. One of these is entitled “Six Degrees of Kevin Bacon”, in which Wlm fans try to connect the aforementioned actor with any other movie star in as few links as possible. I have been thinking of launching a similar parlour game called “Six Degrees of Bertrand Russell”, in which any Wgure from the past 200 years or so could be connected with Bertie in as few steps as possible. Why Bertie rather than, say, Ludwig Wittgenstein (who after all had a stated interest in games)? For two reasons: Wrst, Russell lived to the ripe old age of 97, and thus had the time to interact with a wide variety of people; and secondly he was for most of that long life a celebrity, who rubbed elbows with all manner of individuals, many of whom were either celebrities themselves at the time or came to be celebrated later. As is often pointed out, Russell’s list of acquaintances stretched from Lenin (V.yI.) to Lennon (zJohn), from the Bloomsbury Group to the Doomsday Prophets, from William Gladstone to Harold Wilson.

Given this strong connection to history, it is not surprising that Russell himself would write an essay entitled “How to Read and Understand History”.2 In his Autobiographyz and other works such as Portraits from Memory, Russell made it quite clear that his aristocratic and privileged background gave him access to many of the most important movers and shakers in twentieth-century politics, literature, and academia, areas in which he himself excelled. He was aware that, unlike many of his fellow philosophers, who were known only to a small coterie of fellow deep thinkers, he was an historic Wgure, one who could interact on a personal level with cabinet ministers, Nobel prize-winners in all Welds, press lords, movie stars, presidents and premiers.

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)

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.

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.

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)

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.

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 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.

Disorder and suffering are increasing significantly in our society. Violent crime, unemployment, escape through drug-taking are all on the increase. It is apparent, also, that much of this disorder and suffering, and the anxiety it fosters, is rooted in science and its technological off-spring. The un-employment produced by a micro-technology is only one small example. It is also apparent that one of the principal foundation stones for the scientific enterprise was Christianity.

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.

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.

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)

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.

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)

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.

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)

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)

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)

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)

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)

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)
