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)

We shall see that both these projects are deeply misguided. The first suffers from Searle’s misrepresentation, en masse and individually, of the various materialist theories. To show this, I will focus on the basic claims of token identity specifically, and draw out the inaccuracy of Searle’s straw materialism. This is a shortcut; by showing one conjunct to be false, we may show the conjunction of Searle’s summaries to be false. And, after all, token identity is the most widely held current (...) view. Searle’s second project, I will argue, is characterized by two unfortunate traits: it makes some confused and unsupported claims about supervenience and causality, and, when interpreted most charitably, it is fundamentally indistinguishable from a prevalent account of token identity augmented by supervenience.

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.

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)

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)

IN 1926 IN THE RELATIVE ISOLATION of his hut in the Black Forest Martin Heidegger completed writing the first portion of his influential Being and Time. In the same year at Kenyon College, Ohio, John Dewey delivered a public set of lectures that became The Public and Its Problems. Both were published the following year in 1927. These two books are obviously quite different in topic, style, occasion, and language. Being and Time is a systematic work of fundamental ontology, (...) while The Public and Its Problems is a topical set of lectures in political theory. If we are to look for the basis of a political theory in Heidegger's work, however, we must notice the central negative significance of the concept of "the public" in his account of our everyday life. While Heidegger attacks the dictatorship of the public in contemporary affairs, Dewey in his lectures seeks to revivify the public on behalf of democracy in response to Walter Lippman's decrying its eclipse.

This paper deals with the ethics of using knowledge about a person’s particular psychological make-up, or about the psychology of judgment and decision-making in general, to shape that person’s decisions and behaviors. Various moral concerns emerge about this practice, but one of the more elusive and underdeveloped concerns is the charge of manipulation. It is this concern that is the focus of this paper. I argue that it is not the case that any of the practices traditionally labeled as “manipulation” (...) are ipso facto morally wrong, nor is it even the case that any of these practices always has a single wrong making feature (e.g., infringement on autonomy) that is always present but may be outweighed by other morally relevant factors and be all things considered ethically permissible or morally right. I argue that the moral status depends on the extent to which the instance of influence (1) threatens or promotes autonomy, (2) has good aims and virtuous overtones or bad ones, and (3) fulfills or fails to fulfill duties, obligations, and expectations that arise out of the relationship between the influencer and influenced. I will explain in detail the moral relevance of these factors, showing why each is necessary, criteria for evaluation each, and demonstrating how they work in specific cases. (shrink)

The phenomenon of ambivalence is an important one for any philosophy of action. Despite this importance, there is a lack of a fully satisfactory analysis of the phenomenon. Although many contemporary philosophers recognize the phenomenon, and address topics related to it, only Harry Frankfurt has given the phenomenon full treatment in the context of action theory - providing an analysis of how it relates to the structure and freedom of the will. In this paper, I develop objections to Frankfurt's account, (...) all revolving around the charge that his account contains a serious ambiguity between willing and identifying. With such objections in place, I then develop an analysis that avoids the difficulties and ambiguities that Frankfurt's analysis is prey to. I briefly distinguish ambivalence from other types of internal conflict. This paper aims to offer conceptual clarification on the phenomenon of ambivalence, which will then allow for discussions about the normative merits and demerits of ambivalence, the effects of ambivalence on autonomous action, and methods of resolution of ambivalence.

The dominance in normal awareness of visual percepts, which are linked to space, obscures the fact that most thoughts are non-spatial. It is argued that the mind is intrinsically non-spatial, though in perception can become compresent with spatial things derived from outside the mind. The assumption that the brain is entirely spatial is also challenged, on the grounds that there is a perfectly good place for the non-spatial in physics. A quantum logic approach to physics, which takes non-locality as its (...) starting point, offers a non-reductive way of reconciling the experience of mind with the world description of physics. For further progress it is necessary to place mind first as the key aspect of the universe. (shrink)

As part of a larger research study, we present model language for disclosing financial interests in clinical research to potential research participants, and we describe the empirical basis and theoretical assumptions used in developing the language. The empirical process for creating appropriate disclosure language resulted in a generic disclosure statement for cases in which no risk to participants’ welfare or the scientific integrity of the research is expected, and nine more specific disclosure statements for cases in which some risk is (...) expected. The disclosure statements are not meant to be canonical, but were instead designed to reflect the typical situations in which disclosure of financial interest might be considered by an institutional review board or conflict of interest committee. Individual institutions could modify key phrases to suit their purposes, and others could use the language in future empirical work on informed consent to better refine the options for disclosing financial interests in clinical research.

In our commentary we briefly review the work on the neurological differences between the rational ethical analysis used in professional contexts and the reflexive emotional responses of our daily moral reasoning, and discuss the implications for the claim that our normative arguments should not rely on the emotion of repugnance.

The Scottish Enlightenment provided the fledgling United States of America and its emerging universities with a philosophical orientation. For a hundred years or more, Scottish philosophers were both taught and emulated by professors at Princeton, Harvard and Yale, as well as newly founded colleges stretching from Rhode Island to Texas. This volume in the Library of Scottish Philosophy demonstrates the remarkable extent of this philosophical influence. Selections from William Smith, John Witherspoon, Samuel Stanhope Smith, Archibald Alexander, Alexander Campbell, W.E. Channing, (...) James McCosh, and C.S. Peirce, together with the editor's introductory and explanatory material, provide the modern reader with unprecedented access to this period of intellectual formation. (shrink)

This volume -- a companion to Thomas Reid: Selected Philosophical Writings (2012) -- makes available material from Thomas Reid's autograph manuscripts and student notes of his lectures. It includes an introductory essay by Nicholas Wolterstorff.

'Uncertainty and chance' is a subject with a broad span, in that there is no academic discipline or walk of life that is not beset by uncertainty and chance. In this book a range of approaches is represented by authors from varied disciplines: natural sciences, mathematics, social sciences and medical sciences. At one extreme, this volume is concerned with the foundations of probability. At the other extreme, we have scholars who acknowledge the concept of chance and uncertainty but do not (...) cope with it by means of systematic measurement or quantative analysis. (shrink)

El deseo y oraciones de Juan XXIII pidiendo que el Vaticano II fuera un Pentecostés para la Iglesia, fue ampliamente escuchado por el Señor. El Vaticano II fue una auténtica irrupción del Espíritu sobre la Iglesia, un acontecimiento salvífico, un kairós. Hay un “antes” un “después” del Vaticano II.

Spin gauge models use a real Clifford algebraic structure Rp,q associated with a real manifold of dimension p + q to describe the fundamental interactions of elementary particles. This review provides a comparison between those models and the standard model, indicating their similarities and differences. By contrast with the standard model, the spin gauge model based on R3,8 generates intermediate boson mass terms without the need to use the Higgs-Kibble mechanism and produces a precise prediction for the mass of the (...) top quark. The potential of this model to account for exactly three families of fermions is considered. (shrink)
