Spatial asymmetries are an intriguing feature of directed attention. Recent observations indicate an influence of temperament upon the direction of these asymmetries. It is unknown whether this influence generalises to visual orienting behaviour. The aim of the current study was therefore to explore the relationship between temperament and measures of spatial orienting as a function of target hemifield. An exogenous cueing task was administered to 92 healthy participants. Temperament was assessed using Carver and White's (1994) Behavioural Inhibition System and Behavioural (...) Activation System (BIS/BAS) scales. Individuals with high sensitivity to punishment and low sensitivity to reward showed a leftward asymmetry of directed attention when there was no informative spatial cue provided. This asymmetry was not present when targets were preceded by spatial cues that were either valid or invalid. The findings support the notion that individual variations in temperament influence spatial asymmetries in visual orienting, but only when lateral targets are preceded by a non-directional (neutral) cue. The results are discussed in terms of hemispheric asymmetries and dopamine activity. (shrink)

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

Tendo como pano de fundo a concepção de filosofia, explora-se os diferentes tratamentos do tema da subjetividade conferidos pelo Tractatus e pela obra do que se convencionou chamar de “II Wittgenstein”. A concepção prática do significado inaugurada por esta, a despeito de significar uma drástica ruptura com o espírito do Tractatus, funda-se na preservação do antipsicologismo. Tem-se, portanto, a conciliação entre a concepção prática de significado e o antipsicologismo característico da lógica sublime do Tractatus, da qual o II Wittgenstein se (...) desfaz.AbstractHaving a conception of philosophy in the backgound, I investigate different approaches concerning the topic of subjectivism in the Tractatus and thoughout the writings of what is commonly called as “II Wittgenstein”. The practical conception of meaning that steam from those writings, in spite of being a shift with regards to that of the Tractatus, is based on the preservation of the anti-psychologism. Therefore, there is a conciliation between the practical conception of meaning and the anti-psychologism, by means of which, in the Tractatus, logic is something sublime, which is discarded by the II Wittgenstein.

Despite its invasive nature, specific consent for general anaesthesia is rarely sought—rather consent processes for associated procedures include explanation of risk/benefits. In adult intensive care, because no one can consent to treatments provided to incapacitated adults, standardised consent processes have not developed. In paediatric intensive care, despite the ready availability of those who can provide consent, no tradition of seeking it exists, arguably due to the specialty’s evolution from anaesthesia and adult intensive care. With the current Montgomery-related focus on consent, (...) this seems untenable. We undertook a qualitative study in a specialist children’s hospital colocated paediatric/neonatal intensive care (same medical team) in which parental acceptance of admission and entailed procedures is considered implied by virtue of that admission. Semistructured interviews were carried out with both staff and parents to investigate their views about consent, the current system and a proposedblanket consent system, in which parents actively consent at admission to routine procedures. Divergent views emerged: staff were worried that requiring consent at admission might prove a further emotional burden, whereas parents found providing consent a way of coping, feeling empowered and maintaining control. Inconsistencies were found in the way consent is obtained for your routine procedures. Practice does seem inconsistent with contemporary consent standards for medical intervention. Our findings support the introduction of a blanket consent system at admission together with ongoing bedside dialogue to ensure continuing consent. Both parents and staff expressed concern about avoiding possible harmful delays to children due to parental emotional overload and language difficulties. (shrink)

Si les figures continuent à faire l'objet de l'attention des linguistes, c'est dans le cadre toujours restreint de l'élocution, en dépit d'ouvertures vers la pragmatique, qui minimisent le détail du fait grammatical. Cette étude les aborde dans une perspective non seulement de rhétorique générale mais aussi de linguistique et de philosophie du langage, ce qui conduit à soulever la question même de leur définition. Elle s'appuie sur une conception souple du langage, considéré non comme un code, mais comme un processus (...) qui admet le flou et l'approximation. Les figures ne constituent pas un écart repérable par rapport à une norme, au demeurant introuvable, mais des agencements de faits grammaticaux qui prennent leur sens dans le contexte où ils se trouvent. On passe ainsi de la notion de figure à celle de configuration, ce qui est loin d'être une simple question de terminologie. Il ne s'agit donc pas de proposer une énième liste de figures aux noms savants, mais de mettre en évidence le jeu de mécanismes inscrits dans le logos, qui, en liaison avec l'ethos du locuteur et le pathos de l'interlocuteur, contribuent à la négociation de la distance entre individus à propos d'une question, où Michel Meyer voit l'essentiel de la rhétorique. C'est une nouvelle théorie des figures qui est proposée : loin d'en faire des écarts, elle les inscrit dans le fonctionnement ordinaire du langage. (shrink)

El presente trabajo busca exponer las premisas y la fundamentación teológica que subyace a la moral de Pedro Abelardo, con el fin de mostrar cómo en el sistema filosófico de dicho autor, conocido por su racionalismo, hay una justificación que extralimita dicho sistema. Para ello, se expondrá la terminología clave de su moral, la aplicación práctica de dichos conceptos, y una serie de objeciones tanto teológicas como filosóficas.

Contributors discuss the work of thinkers such as Cass Sunstein and Jeremy Waldron in their exploration of the relations between philosophical theories and everyday life. They elucidate major attempts to reconcile theory with practice in the Western tradition, from Herodotus to Heidegger, and discuss topics such as the role of theory in judicial decision-making and the political implication of theory. Of interest to philosophers, lawyers, and social scientists. Annotation copyright by Book News, Inc., Portland, OR.

Bien que Carnap soit surtout connu pour son appartenance à l’empirisme logique, qui rejette le synthétique a priori et la métaphysique kantienne en général, sa thèse sur l’espace (1922) fut rédigée dans le double contexte des multiples variétés du néokantisme et d’une réflexion mathématique, physique et philosophique sur le concept d’espace. Dans cette thèse et dans le mémoire de 1920 sur la géométrie, il s’efforce de surmonter les difficultés soulevées par le concept d’espace en en distinguant plusieurs significations et plusieurs (...) sortes. Ce faisant, il défend une position originale qui emprunte aux différentes formes du néokantisme de l’époque sans se réduire pour autant à aucune d’elles. (shrink)

Name der Zeitschrift: Der Islam Jahrgang: 94 Heft: 1 Seiten: 94-114.

This chapter discusses a re-emerging topic in Cartesian scholarship—mind and body interaction. A number of thinkers, from his contemporaries onward, have maintained that Descartes' account of his two substances rules out the possibility of the interaction that he attempted to defend. Often, however, the ground for asserting this impossibility has been left less than explicit. Recent discussion has attempted to clarify the issue by asking whether there can be specified grounds within Descartes' philosophy which are sufficient to rule out mind–body (...) interaction. There are three elements of Descartes' thinking which might seem to create problems for mind–body interaction—his insistence that mind and body are absolutely distinct substances, his own restrictions on possible causal relations, and his views on the freedom of the will. Recent work has focused on the first two of these issues. The chapter's goal is to suggest that an essential element of Descartes' worldview has been overlooked in this recent discussion, and to show that once it is taken into account many of the apparent difficulties about Cartesian interaction can be resolved.

W pracy tej podejmowane jest zagadnienie form przejściowych ewolucji biologicznej w jej najbardziej znanej formie, czyli problemu „brakującego ogniwa”. Problem ten często pojawiający się w rozważaniach wczesnych darwinistów, został całkowicie zarzucony przez współczesnych ewolucjonistów. Zniknięcie kwestii brakującego ogniwa z zainteresowań współczesnej biologii tłumaczy się tym, iż poszukiwane formy przejściowe zostały już odnalezione. Sam zaś problem uważa się za nieistotny, gdyż spowodowany niekorzystnym wpływem różnych czynników pozanaukowych. Celem pracy jest wskazanie przyczyn, które doprowadziły do zmiany sposobu postrzegania owej problematyki. Szczególna uwaga (...) zostanie poświęcona relacji taksonomii do sposobu, w jaki postrzegano poszukiwane brakujące ogniwa. Cały zaś problem brakującego ogniwa, jego przyczyny i zniknięcia, jest interpretowany jako wynik przemian metanaukowych, jakie zaszły w trakcie rozwoju taksonomii. (shrink)

Original essays by leading scholars on Plotinus' philosophy of nature.

In Houston several projects in philosophy for children are in process or are about to be initiated. To begin with, I am continuing the work in philosophy for children which I began at the Laboratory School of the University of Missouri in 1976. My earlier work in Missouri focused primarily on the effect of philosophy for children as adjunct in developing children's syntactic skills and their understanding of science. Since arriving here in Houston, I have operated philosophy for children classes (...) for gifted students in the Clear Creek Independent School District of Houston. My interest in philosophy as an adjunct to science education continues and is now accompanied by an additional concern: the use of philosophy to increase student appreciation and understanding of mathematics.

In reply to the contributions to Social Imaginaries vol. 4, no. 1, this article reviews the development of the research programme that the author has been pursuing over more than three decades. It places the emphasis on the conceptual and methodological requirements for a historical sociology of social change. It insists, on the one hand, on the need to avoid overly strong conceptual presuppositions to analyze social phenomena of large scale and long duration, while, on the other hand, sustaining the (...) notion that a minimum of social and political philosophy as well as philosophy of history is necessary to comprehend the ways in which history is directed. Further emphasis is given to the difficulties that arise when studying social phenomena before 1800 and outside Europe, due to the strong epistemic impact European global domination has had since the “great divergence” at around 1800. The article concludes with reflections on the adequate kind of conceptual distinctions that are needed when analyzing large-scale phenomena such as “societies” as well as on the link between scholarly work and a critical, action-oriented diagnosis of the present time.

In framing the concept of rational consensus, decision theorists have tended to defer to an older, established literature on social welfare theory for guidance on how to proceed. But the uncritical adoption of standards meant to regulate the reconciliation of differing interests has unduly burdened the development of rational methods for the synthesis of differing judgments. In particular, the universality conditions typically postulated in social welfare theory, which derive from fundamentally ethical considerations, preclude a sensitive treatment of special cases when (...) carried over to the realm of judgment aggregation, especially in the case of probabilistic judgment.

En palabras del rector de la Pontificia Universidad Católica del Perú, coeditora de este libro, quien lea estas páginas podrá apreciar cómo Alberto Wagner de Reyna, alumno del filósofo alemán, nos aproxima a una renovada comprensión de los temas que cautivaron la reflexión de Heidegger, y nos invita a adentrarnos con él por esas "sendas del bosque" en las que el hombre que busca su autenticidad celebra la fiesta de la meditación serena.

A decision problem in which the values of the decision variables must sum to a fixed positive real number s is called an "allocation problem," and the problem of aggregating the allocations of n experts the "allocation aggregation problem." Under two simple axiomatic restrictions on aggregation, the only acceptable allocation aggregation method is based on weighted arithmetic averaging (Lehrer and Wagner, Rational Consensus in Science and Society, 1981). In this note it is demonstrated that when the values assigned to (...) the variables are restricted to a finite set (as is always the case in practice), the aforementioned axioms allow only dictatorial aggregation.

Scholarly correspondence can be as insightful as scholarly work itself, as it often documents the motivating forces of its writers’ intellectual ideas while illuminating their lives more clearly. The more complex the authors’ scholarly works and the more troubled the eras in which they lived, the more substantial, and potentially fascinating, their correspondence. This is especially true of the letters between Alfred Schutz and Eric Voegelin. The scholars lived in incredibly dramatic times and produced profound, complex works that continue to (...) confound academics. The communication between these two giants of the social sciences, as they sent their thoughts to one another, was crucial to the work of both men. _A Friendship That Lasted a Lifetime: The Correspondence between Alfred Schutz and Eric Voegelin _demonstrates that Schutz and Voegelin shared a remarkable friendship: they first met as students in Vienna in the 1920s and found themselves great partners in discussion; years later they were pushed out of Europe by Nazi pressure and went to work at separate American universities. For twenty years they wrote each other, developing their respective scientific works in that dialogue. The letters bear witness to their friendship during the years they spent in exile in the United States, and they document the men’s tentative attempts at formulating the theories of “lifeworld” and “gnosis” associated with Schutz and Voegelin today. The entire collection of 238 letters was printed in German in 2004, but this edited volume is the first to present their correspondence in English and offers a selection of the most important letters—those that contributed to the thinkers’ theoretical discussions and served as background to their most significant thoughts. Editors Gerhard Wagner and Gilbert Weiss do not analyze Schutz’s and Voegelin’s works in light of the correspondence—rather, they present the collection to create a framework for new interpretations. _A Friendship That Lasted a Lifetime_ takes a unique look at two major social scientists. This volume is a valuable resource in the study of Voegelin’s political philosophy and Alfred Schutz’s contribution to American sociology and marks an important addition to the literature on these remarkable men. Showing how scholarly discourse and the dialogue of everyday life can shed light on one another, the book finally presents this correspondence for an American audience and is not to be missed by scholars of philosophy and sociology.

Spekulative Theorien bedürfen laut einigen Forschern keiner experimentellen Überprüfung, um als wissenschaftlich zu gelten. Dieser Ansatz untergräbt die Wissenschaft.Im vergangenen Jahr nahm eine Debatte in der Physik eine beunruhigende Wende: Nicht alle fundamentalen Theorien lassen sich anhand von Beobachtungen überprüfen und so fordern einige Wissenschaftler, das Vorgehen in der theoretischen Physik anzupassen. Sei eine Theorie nur ausreichend elegant und aussagekräftig, so ihr Appell, müsse diese nicht experimentell überprüft werden – das bricht mit jahrhundertealter philosophischer Tradition, nach der wissenschaftliche Erkenntnis sich (...) erst durch empirische Befunde bewähren muss. Wir kritisieren den neuen Ansatz scharf, denn wie der Wissenschaftstheoretiker Karl Popper bereits feststellte: Jede wissenschaftliche Theorie muss falsifizierbar sein. (shrink)
