I present solutions to several questions of Paul Bankston [2] by means of another version of the ultracoproduct construction, and explain the relation of ultracoproduct of compact Hausdorff spaces to other constructions combining topology, algebra and logic.

The paper presents and defends a Bayesian theory of trust in social networks. In the first part of the paper, we provide justifications for the basic assumptions behind the model, and we give reasons for thinking that the model has plausible consequences for certain kinds of communication. In the second part of the paper we investigate the phenomenon of overconfidence. Many psychological studies have found that people think they are more reliable than they actually are. Using a simulation environment that (...) has been developed in order to make our model computationally tractable we show that in our model inquirers are indeed sometimes better off from an epistemic perspective overestimating the reliability of their own inquiries. We also show, by contrast, that people are rarely better off overestimating the reliability of others. On the basis of these observations we formulate a novel hypothesis about the value of overconfidence. (shrink)

According to the Argument from Disagreement (AD) widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by moral facts, either because there are no such facts or because there are such facts but they fail to influence our moral opinions. In an innovative paper, Gustafsson and Peterson (Synthese, published online 16 October, 2010) study the argument by means of computer simulation of opinion dynamics, relying on the well-known model of Hegselmann and Krause (J Artif (...) Soc Soc Simul 5(3):1–33, 2002; J Artif Soc Soc Simul 9(3):1–28, 2006). Their simulations indicate that if our moral opinions were influenced at least slightly by moral facts, we would quickly have reached consensus, even if our moral opinions were also affected by additional factors such as false authorities, external political shifts and random processes. Gustafsson and Peterson conclude that since no such consensus has been reached in real life, the simulation gives us increased reason to take seriously the AD. Our main claim in this paper is that these results are not as robust as Gustafsson and Peterson seem to think they are. If we run similar simulations in the alternative Laputa simulation environment developed by Angere and Olsson (Angere, Synthese, forthcoming and Olsson, Episteme 8(2):127–143, 2011) considerably less support for the AD is forthcoming.

What does it mean for an agent faced with choice under uncertainty to “know” something? While a variety of mathematical methods are available to construct formal models to answer this question, the combination of different approaches may lead to unsettling paradoxes. I propose a unified theory that eliminates such inconsistencies by relying on a sharp conceptual distinction between information the decision-maker observes and how much of that information she can cognitively process. The resulting model allows for natural decision-theoretic characterizations of (...) comparing different amounts of information. (shrink)

Performing surgery in the developing world presents unique challenges and dilemmas for the visiting physician from an industrialized country. Language barriers, widespread, profound pathology, and lack of adequate facilities are obvious hurdles. A more subtle problem, though every bit as significant, is that the principles and procedures we routinely utilize at home to uphold ethical standards of care and to aid us in decision-making are often poorly applicable in the developing world. Acknowledging that cultural factors play a primary role in (...) every aspect of their interaction with patients, physicians must scrutinize and even modify the tools they employ when attempting to deliver ethical care in foreign ..

Aron Vinegar’s essay explores art history and visual culture’s dependence on a phenomenological conception of world, which is based on a hermeneutics of facticity, intentionality, and ontological difference. He argues that the ‘basic concept’ of world has structured the field of art history and visual culture in implicit and explicit ways, thus dictating many of its commitments and concerns. One of the primary limitations of this commitment to world, is that it has resulted in art history and visual culture’s (...) tendency to concern itself with a very small portion of existence, usually human existence, in its emphasis on hermeneutics and facticity, thus foreclosing on a more generous and speculative ontology, ethics, and politics. The concept of “world” suggests an overarching totality, an interconnected field of meaning and sense, often indicated by a tacit and resonate tonality. But there is no overarching “world” or “world-view” that can provide us with an overview of or container for the myriad worlds of things. An art history that is willing to consider that the world does not exist would acknowledge and embrace the fact that there is no overall focus, which can encompass things and events in all their spatio-temporal complexity. It would entail a practice attentive to a “supple and inflected bathmology” (Vinegar prefers this phrase to “flat ontology”) in its refusal to emphasize “privileged ontological scenes” predicated on hierarchies of ontological difference, and subsuming things and experience within the structures of phenomenological intentionality. To initiate such a practice, Vinegar suggests an embrace of what he terms “ontological indifference,” a robust notion of habit, and a temporal logic that would be fully attentive to a pluriverse of multiple existences and eruptions of substance, which extend well beyond ‘our’ realms of significance and meaning, cares and concerns, laughter and joy, losses and mournings.

The significance of the ‘Republic of Letters’ as a Pan-European and cross-national concept is often addressed in scholarship on early modern intel­lectual history. Focusing on an extensive digital epistolary corpus of authors of East Central European descent from c. 1600 to c. 1800, this article aims to readdress this argument by analyzing the currency of the most frequently used terms in Latin that denote a sense of scholarly community (viz. respu­blica literaria and orbis literatus) from a combined quantitative and qualitative (...) approach. Based on the results of this analysis, it is argued that with respect to this geography, terms referring to the Republic of Letters were not as vital and ubiquitous as modern scholarship may perhaps lead one to believe. As the supposed increasing geographical spread and frequency of these terms are oftentimes mentioned as signs of the growing currency of their underlying concept, it is important to realize that their continental occurrence seems, in fact, limited at best and erratic at worst. Consequently, it is argued that concerning the analysis of individual authors, the methodology adopted in this study can only yield a meaningful discussion in the case of a relatively large number of occurrences, as the absence of these terms could be regarded as the default ‘standard’ in the regions under discussion—and possibly beyond.

According to the traditional Bayesian view of credence, its structure is that of precise probability, its objects are descriptive propositions about the empirical world, and its dynamics are given by conditionalization. Each of the three essays that make up this thesis deals with a different variation on this traditional picture. The first variation replaces precise probability with sets of probabilities. The resulting imprecise Bayesianism is sometimes motivated on the grounds that our beliefs should not be more precise than the evidence (...) calls for. One known problem for this evidentially motivated imprecise view is that in certain cases, our imprecise credence in a particular proposition will remain the same no matter how much evidence we receive. In the first essay I argue that the problem is much more general than has been appreciated so far, and that it’s difficult to avoid without compromising the initial evidentialist motivation. The second variation replaces descriptive claims with moral claims as the objects of credence. I consider three standard arguments for probabilism with respect to descriptive uncertainty—representation theorem arguments, Dutch book arguments, and accuracy arguments—in order to examine whether such arguments can also be used to establish probabilism with respect to moral uncertainty. In the second essay, I argue that by and large they can, with some caveats. First, I don’t examine whether these arguments can be given sound non-cognitivist readings, and any conclusions therefore only hold conditional on cognitivism. Second, decision-theoretic representation theorems are found to be less convincing in the moral case, because there they implausibly commit us to thinking that intertheoretic comparisons of value are always possible. Third and finally, certain considerations may lead one to think that imprecise probabilism provides a more plausible model of moral epistemology. The third variation considers whether, in addition to conditionalization, agents may also change their minds by becoming aware of propositions they had not previously entertained, and therefore not previously assigned any probability. More specifically, I argue that if we wish to make room for reflective equilibrium in a probabilistic moral epistemology, we must allow for awareness growth. In the third essay, I sketch the outline of such a Bayesian account of reflective equilibrium. Given that this account gives a central place to awareness growth, and that the rationality constraints on belief change by awareness growth are much weaker than those on belief change by conditionalization, it follows that the rationality constraints on the credences of agents who are seeking reflective equilibrium are correspondingly weaker.

What is the sense of saying “now”? We are used to the established temporal relations by their points of reference (like “yesterday”), distinguished one from the other by measurement and the counting of time (which uses yardsticks, like “day”). So, is the now only another one of these points? Husserl tells us that is not only looking at the constituted time and already shared in common by the world that we will comprehend what is the sense of the now. In (...) this article, I try to follow Husserl’s theory of time with the intent to defend how the phenomenological perspective can clarify the relevant distinctions between “point” and “now”, especially when we comprehend “now” as an origin that closes in itself problems categorically distinct from those referred to the measurement in objective time.

By age 85, most adults manifest some degree of motor impairment. However, in most individuals a specific etiology for motor decline and treatment to modify its inexorable progression cannot be identified. Recent clinical-pathologic studies provide evidence that mixed-brain pathologies are commonly associated with late-life motor impairment. Yet, while nearly all older adults show some degree of accumulation of Alzheimer’s disease and related dementias pathologies, the extent to which these pathologies contribute to motor decline varies widely from person to person. Slower (...) or faster than expected motor decline in the presence of brain injury and/or pathology has been conceptualized as more or less “resilience” relative to the average person This suggests that other factors, such as lifestyles or other neurobiologic indices may offset or exacerbate the negative effects of pathologies via other molecular pathways. The mechanisms underlying neural motor resilience are just beginning to be illuminated. Unlike its cousin, cognitive resilience which is restricted to neural mechanisms above the neck, the motor system extends the total length of the CNS and beyond the CNS to reach muscle and musculoskeletal structures, all of which are crucial for motor function. Building on prior work, we propose that by isolating motor decline unrelated to neuropathologies and degeneration, investigators can identify genes and proteins that may provide neural motor resilience. Elucidating these molecular mechanisms will advance our understanding of the heterogeneity of late-life motor impairment. This approach will also provide high value therapeutic targets for drug discovery of therapies that may offset the negative motor consequences of CNS pathologies that are currently untreatable.

Silence, Implicite et Non-Dit chez Rousseau/Silence, the Implicit, and the Unspoken in Rousseau prend acte d'un grand nombre de publications ayant trait à l'analyse par Rousseau des langues et du langage, de la parole par rapport à l'écriture, de la voix (y compris la voix de la nature). Mais ce volume se consacre tout particulièrement au fonctionnement et aux effets du silence, de l'implicite et du non-dit dans la pensée de Rousseau. Son approche est à la fois polyvalente et cohérente, (...) et ses réflexions sur le silence sont associées à d'autres préoccupations esthétiques, politiques, et morales de son œuvre. Silence, Implicite et Non-Dit chez Rousseau/Silence, the Implicit, and the Unspoken in Rousseau capitalizes on a great number of publications dealing with Rousseau's analysis of languages and language, speech versus writing, of voice (including the voice of nature). But this volume is particularly dedicated to the study of the functioning and the effects of silence, the implicit and the unspoken in Rousseau's thought. His approach is both polyvalent and consistent, and his reflections on silence are associated with other aesthetic, political, and moral concerns in his work. (shrink)

The phenomenon of base-rate neglect has elicited much debate. One arena of debate concerns how people make judgments under conditions of uncertainty. Another more controversial arena concerns human rationality. In this target article, we attempt to unpack the perspectives in the literature on both kinds of issues and evaluate their ability to explain existing data and their conceptual coherence. From this evaluation we conclude that the best account of the data should be framed in terms of a dual-process model of (...) judgment, which attributes base-rate neglect to associative judgment strategies that fail to adequately represent the set structure of the problem. Base-rate neglect is reduced when problems are presented in a format that affords accurate representation in terms of nested sets of individuals. (shrink)

A travers les Dimensions de la conscience historique, Raymond Aron s'impose comme l'un des penseurs majeurs de l'histoire au XXe siecle. Apres les bouleversements issus du second conflit mondial, Raymond Aron pense le monde a l'aune de l'installation durable du communisme a l'Est de l'Europe, de la fin de la colonisation, des mutations que signale une phase de progres technique encore inconnue dans les societes developpees. Il prend acte du changement radical que marque pour la condition humaine l'avenement (...) de l'ere nucleaire. Face a ces mutations, le philosophe a plus que jamais le devoir de penser l'histoire et la liberte de l'homme face a l'evenement. Dialoguant avec Thucydide, combattant l'idee d'une fin de l'histoire avancee par Spengler et Toynbee et plus encore par la teleologie marxiste, il poursuit la reflexion sur les limites de l'objectivite historique engagee au cours des annees 1930.Les Dimensions de la conscience historique n'ont cesse de nourrir les debats sur l'histoire. Il demeure aujourd'hui un ouvrage indispensable pour reflechir a notre condition historique. (shrink)

Recent work on the logical theory of confirmation has centered on accounts of the confirmation of hypotheses relative to auxiliary assumptions or background theory. Whether such relative confirmation actually increases the credibility of the (relatively) confirmed hypothesis will depend in various ways on the epistemic status of the auxiliaries involved. Most obviously, if the auxiliaries are not themselves credible, confirmation relative to them will not increase the credibility of the hypothesis thus confirmed. A complete theory of confirmation must thus combine (...) an account of relative confirmation with an account of the route from relative confirmation to real confirmation. Some recent criticisms of hypothetico-deductive and bootstrapping accounts of relative confirmation are undermined by failure to appreciate the limitations of relative confirmation. (shrink)
