C i lewis, regarding himself as a pragmatist, repeatedly attempts to identify truth with verification. it is here argued, however, that a correspondence or semantic theory is required by (1) lewis's interpretation of objective judgments in terms of "possible experience" and of possible experience in terms of counterfactual conditions; (2) his distinction between the justification of knowledge and the truth of knowledge; and (3) his logical analysis of truth in terms of the extension (known or unknown) of propositions. it is (...) then argued that verification determines knowledge but reality determines truth, and that lewis himself emphasizes "the transcendence by reality of our present knowledge of it.".

THE problem of religious knowledge may be stated very simply. If there is a real God, how can we find out that fact? The present discussion assumes that this is just what we must find out, if there is to be any possibility of a philosophically valid religion; for the essential element in religion is God, and consequently the essential philosophical question in regard to religion is that of the reality of God.

In an attempt to extract a coherent and still relevant structure of thought from its obsolete encumbrances, some of the recent interpretations of Kant have been needlessly hampered by neglect of the important concept of ‘possible experience’. Failure to make the full use of this concept that Kant himself made has inevitably been damaging to the Kantian doctrine of phenomenal objectivity; and any version of Kant that is so damaged falls drastically short of the original. I should like, therefore, after (...) making the problem a little clearer, to examine the concept of possible experience as Kant presents it; to attempt a clarification of difficulties in his presentation that may have contributed to the tendency to neglect the concept; and finally to indicate briefly the unfortunate consequences of this neglect in some recent instances.

Research on sleep loss and vigilance both focus on declines in cognitive performance, but theoretical accounts have developed largely in parallel in these two areas. In addition, computational instantiations of theoretical accounts are rare. The current work uses computational modeling to explore whether the same mechanisms can account for the effects of both sleep loss and time on task on performance. A classic task used in the sleep deprivation literature, the Psychomotor Vigilance Test, was extended from the typical 10-min duration (...) to 35 min, to make the task similar in duration to traditional vigilance tasks. A computational cognitive model demonstrated that the effects of time on task in the PVT were equivalent to those observed with sleep loss. Subsequently, the same mechanisms were applied to a more traditional vigilance task—the Mackworth Clock Task—providing a good fit to existing data. This supports the hypothesis that these different types of fatigue may produce functionally equivalent declines in performance. (shrink)

This is a collection of essays from an international group of scholars that explore the ways in which the ancient problem of universals was transformed in modern philosophy. Essays consider the various forms of "Platonism," "conceptualism" and "nominalism" in the writings of a broad range of modern thinkers.

Visual working memory is a construct hypothesized to store a small amount of accurate perceptual information that can be brought to bear on a task. Much research concerns the construct's capacity and the precision of the information stored. Two prominent theories of VWM representation have emerged: slot-based and continuous-resource mechanisms. Prior modeling work suggests that a continuous resource that varies over trials with variable capacity and a potential to make localization errors best accounts for the empirical data. Questions remain regarding (...) the variability in VWM capacity and precision. Using a novel eye-tracking paradigm, we demonstrate that VWM facilitates search and exhibits effects of fixation frequency and recency, particularly for prior targets. Whereas slot-based memory models cannot account for the human data, a novel continuous-resource model does capture the behavioral and eye tracking data, and identifies the relevant resource as item activation.

Michela Bella & Anna Boncompagni – This conversation will focus on your role and your position with respect to pragmatism; those who you consider allies and enemies in the field; and then finally your ideas about the future of philosophy and the future of pragmatism. You worked with famous philosophers like Carnap, Reichenbach and many others. But let us start from the beginning. Hilary Putnam – My alma mater was the University of Pennsylvania. The first teacher who really influenced (...) me there... (shrink)

Michela Bella & Matteo Santarelli – What was the state of Pragmatism studies when you first encountered pragmatism? Larry A. Hickman – After completing my undergraduate degree in psychology I decided that I wanted to study philosophy. In order to prepare for graduate school, I spent a year taking philosophy courses at the University of Texas in Austin. The faculty included Charles Hartshorne, who was co-editor of the Peirce Collected Papers. There was also David L. Miller and George Gentry, (...) b... (shrink)

When we use secure computer systems, we engage with carefully orchestrated and ordered interactions called “security ceremonies”, all of which exist to assure security. A great deal of attention has been paid to improving the usability of these ceremonies over the last two decades, to make them easier for end-users to engage with. Yet, usability improvements do not seem to have endeared end users to ceremonies. As a consequence, human actors might subvert the ceremony’s processes or avoid engaging with it. (...) Here, we consider whether beautification could be one way of making ceremonies more appealing. To explore beautification in this context, we carried out three studies. Study 1 surveyed 250 participants to derive a wide range of potential dimensions of “beautiful ceremonies”. These statements were sorted into dominant themes and converted into statements, which fed into the second study, with 309 respondents, to reveal the dominant dimensions constituting beauty. Study 3 asked 41 participants to carry out a Q-sort, which revealed the ways that people combine the identified dimensions when characterising security ceremonies as “beautiful”. These studies have allowed us to pin down the perceived dimensions of beauty in the context of security ceremonies, and also to understand how people combine these dimensions in different ways in judging security ceremonies to be beautiful, confirming the old adage of beauty being “in the eye of the beholder”. We conclude by highlighting the constraints imposed by the overarching requirement for security to be maintained in the face of any usability improvements and beautification endeavours. (shrink)

Ontology after Philosophical Psychology develops a theoretical and historical analysis of William James’s psychology of the stream of consciousness and its connections with his philosophy of radical empiricism. This context enables a fuller understanding of James’s epistemological effort to deal with science, as well as his pluralistic metaphysics.

In his well-known Discourse on Metaphysics , Leibniz puts individual substance at the basis of metaphysical building. In so doing, he connects himself to a venerable tradition. His theory of individual concept, however, breaks with another idea of the same tradition, that no account of the individual as such can be given. Contrary to what has been commonly accepted, Leibniz’s intuitions are not the mere result of the transcription of subject-predicate logic, nor of the uncritical persistence of some old metaphysical (...) assumptions. They grow, instead, from an unprejudiced inquiry about our basic ontological framework, where logic of truth, linguistic analysis, and phenomenological experience of the mind’s life are tightly interwoven. Leibniz’s struggle for a concept capable of grasping concrete individuals as such is pursued in an age of great paradigm changes – from the Scholastic background to Hobbes’s nominalism to the Cartesian ‘way of ideas’ or Spinoza’s substance metaphysics – when the relationships among words, ideas and things are intensively discussed and wholly reshaped. This is the context where the genesis and significance of Leibniz’s theory of ‘complete being’ and its concept are reconstrued. The result is a fresh look at some of the most perplexing issues in Leibniz scholarship, like his ideas about individual identity and the thesis that all its properties are essential to an individual. The questions Leibniz faces, and to which his theory of individual substance aims to answer, are yet, to a large extent, those of contemporary metaphysics: how to trace a categorial framework? How to distinguish concrete and abstract items? What is the metaphysical basis of linguistic predication? How is trans-temporal sameness assured? How to make sense of essential attributions? In this ontological framework Leibniz’s further questions about the destiny of human individuals and their history are spelt out. Maybe his answers also have something to tell us. This book is aimed at all who are interested in Leibniz’s philosophy, history of early modern philosophy and metaphysical issues in their historical development. (shrink)

Although most of us know that human beings cannot and should not be replaced by computers, we have great difficulties saying why this is so. This paradox is largely the result of institutionalizing several fundamental misconceptions as to the nature of both trustworthy objective and moral knowledge. Unless we transcend this paradox, we run the increasing risks of becoming very good at counting without being able to say what is worth counting and why. The degree to which this is occurring (...) is the degree to which the computer revolution is already over — and the degree to which we human beings have lost. (shrink)

Gli aspetti concreti e le ricadute pratiche della filosofia sono da qualche tempo al centro dell'attenzione sia degli specialisti - che si interrogano sulla portata e il significato della loro materia anche fuori dalle accademie - sia dei non filosofi - che affollano festival culturali e interrogano i filosofi sui media. Sulle diverse fogge assunte dalla filosofia di fronte alla pratica riflettono gli autori di questi saggi, facendo riferimento tanto a quelle contenute nel sapere consegnatoci in duemilacinquecento anni da questa (...) disciplina, quanto a quelle più recenti, volte a rinnovare il suo rapporto con la quotidianità - le cosiddette "pratiche filosofiche". Un ventaglio di sguardi diversi tra loro, che privilegiano ora la sapienza e la logica, ora la saggezza e la cura, che hanno però in comune l'interesse a pensare le sfide della contemporaneità e le conseguenze pratiche che la filosofia è in grado di offrire a ciascuno di noi, ma anche l'idea che la filosofia non sia una mera disciplina speculativa, ma sia invece indispensabile agli uomini - a tutti gli uomini - per dar senso alla loro vita.

The thirteenth-century Ancrene Wisse is one of the major works of early Middle English prose, and was repeatedly revised and adapted for different audiences. It has attracted much attention from students of church history and women's studies as a highly influential, important example of pastoral guidance for women religions. This is the first edition to bring together the full manuscript evidence, and to set it in its broader cultural and institutional context. Volume II will be published in 2006.

The Ancrene Wisse, a guide for female recluses written in the West Midlands in the early thirteenth century, and the closely related religious works of the `Katherine Group', offer a vivid insight into the religious life of the time, and their rich and varied prose style blends Latin and native English stylistic traditions with remarkable skill and assurance. The difficulty of their language, however, has made them largely inaccessible except to experts in Middle English, and this edition is designed to (...) introduce them to a wider audience, including undergraduates with limited experience of Middle English and specialists in other disciplines, particularly history, theology, and women's studies. It provides a representative selection in new and readable critical texts, with a general introduction, notes, a select glossary, and interleaved translations. (shrink)

It is a question that I keep (...) asking myself! But I am glad to share this more publicly, so that peo... (shrink)

Leibniz introduit l’expression « ⁰⁄₀ » en 1672 dans un écrit mathématique sur les séries numériques pour exprimer la somme des unités. Il s’agit très probablement d’une des premières apparitions de cette expression dans l’histoire des mathématiques. Leibniz cependant l’abandonne aussitôt. Elle apparaît à nouveau dans le contexte du calcul différentiel au moment où celui-ci fait débat à l’Académie royale des sciences. Une des questions les plus saillantes soulevées par l’introduction du nouveau calcul est de savoir si la notion de (...) différentielle doit être distinguée, dans la pratique, du zéro absolu. Cet article examine les efforts effectués, dans le cadre d’une nouvelle pratique mathématique, pour donner un sens à l’expression « ⁰⁄₀ ». On verra comment cette expression cesse de représenter une impossibilité algébrique, à condition de ne plus penser « 0 » comme un zéro absolu. Désormais, elle est le signe de l’existence d’une singularité d’une courbe. L’analyse de cette construction de sens met en évidence combien la représentation diagrammatique des caractères impliqués dans le calcul était importante pour les premiers pratiquants du calcul différentiel.

Based on social-cognitive theory, this article proposes a model that seeks to explain why high status organizational members engage in unethical behavior. We argue that status differentiation in organizations creates social isolation which initiates activation of high status group identity and a deactivation of moral identity. We further argue that high status group identity results in insensitivity to the needs of out-group members which, in turn, results in lessened motivation to selfregulate ethical decision making. As a result of this identity (...) activation, we demonstrate how high status individuals will be more vulnerable to engaging in unethical activities. Individual-level moderators of the relationships are also discussed. (shrink)
