In Topoi/Graphein Christian Abrahamsson maps the paradoxical limit of the in-between to revealthat to be human is to know how tolive with the difference between the known and the unknown. Using filmic case studies, including CodeInconnu, Lord of the Flies, and Apocalypse Now,and focusing on key concerns developed in the works of the philosophers Deleuze, Olsson, and Wittgenstein, Abrahamsson starts within the notion of fixed spatiality, in whichhuman thought and action are anchored in the given of identity. (...) He then movesthrough a social world in which spatiotemporal transformations are neitherfixed nor taken for granted. Finally he edges into the pure temporality that liesbeyond the maps of fixed points and social relations. Each chapter is organized into two subjects: topoi, orexcerpts from the films, and graphein, the author's interpretation ofpresented theoriesto mirror the displacements,transpositions, juxtapositions, fluctuations, and transformations between delimited categories. A landmark work in the study of human geography, Abrahamsson's book proposes that academic and intellectual attention should focus on the spatialization between meaning and its materialization in everyday life.

In quantity discrimination tasks, adults, infants and animals have been sometimes observed to process number only after all continuous variables, such as area or density, have been controlled for. This has been taken as evidence that processing number may be more cognitively demanding than processing continuous variables. We tested this hypothesis by training mosquitofish to discriminate two items from three in three different conditions. In one condition, continuous variables were controlled while numerical information was available; in another, the number was (...) kept constant and information relating to continuous variables was available; in the third condition, stimuli differed for both number and continuous quantities. Fish learned to discriminate more quickly when both number and continuous information were available compared to when they could use continuous information only or number only; there was no difference in the learning rate between the two latter conditions. Our results do not support the hypothesis that processing numbers imposes a higher cognitive load than processing continuous variables. Rather, they suggest that availability of multiple information sources may facilitate discrimination learning. (shrink)

According to recent studies in developmental psychology and neuroscience, symbolic language is essentially intersubjective. Empathetically relating to others renders possible the acquisition of linguistic constructs. Intersubjectivity develops in early ontogenetic life when interactions between mother and infant mutually shape their relatedness. Empirical fndings suggest that the shared attention and intention involved in those interactions is sustained as it becomes internalized and embodied. Symbolic language is derivative and emerges from shared intentionality. In this paper, we present a formalization of shared intentionality (...) based upon a quantum approach. From a phenomenological viewpoint, we investigate the nonseparable, dynamic and sustainable nature of social cognition and evaluate the appropriateness of quantum interaction for modelling intersubjectivity.

"....Cochin...a été presque unanimement considéré par ses contemporains comme un artiste de première importance....Les historiens d'art du XXe siècle ne sont pas moins unanimes pour lui accorder une place centrale dans la vie artistique de son temps."--Introduction, p. 3.

In two recent books, I have drawn on hundreds of studies in psychology in order to systematically develop and empirically support a new conception of the character traits which I claim most people possess. Here I will focus on just one underexplored area of the psychological literature – research on harmful as opposed to helpful behavior – and use it in a preliminary way to further support my positive view.

The book of Aristarchus of Samos, On the distances and sizes of the sun and moon, is one of the few pre-Ptolemaic astronomical works that have come down to us in complete or nearly complete form. The simplicity and cleverness of the basic ideas behind the calculations are often obscured in the reading of the treatise by the complexity of the calculations and reasoning. Part of the complexity could be explained by the lack of trigonometry and part by the fact (...) that Aristarchus appears unwilling to make some simplifications that could be simply taken for granted. But an important part of the complexities is due to some unnecessary inconsistencies, as recently discovered by Berggren and Sidoli (Arch Hist Exact Sci 61:213–254, 2007). In the first part of this paper, I will try to show that some of these inconsistencies are just apparent. But the complexity of the calculations and reasoning is not the only reason that could disturb a reader of the treatise. The great inaccuracy—even for the measurement methods and instruments available at those times—of one of the three input values of the treatise is really astonishing. In the sixth and last hypothesis, Aristarchus states that the moon’s apparent size is equal to 2∘\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$^{\circ }$$\end{document}, while the correct value is one-fourth of that. Some attempts have been made in order to explain such a big value, but all of them have problems. In the second part of this paper, I will propose a new speculative but plausible explanation of the origin of this value. (shrink)

Příspěvek vychází z autorova disertačního projektu, který mapuje myšlenkovou spřízněnost mezi Hansem Blumenbergem a jednotlivými filosofy tzv. Ritterovy školy, tedy Odo Marquardem, Hermannem Lübbem, Robertem Spaemannem a Martinem Krielem. Autor předkládá obecnou charakteristiku Ritterovy školy a „skeptické generace“ (H. Schelsky), hledá argumenty, které by osvětlily, proč bývá zdůrazňována spřízněnost mezi Blumenbergem a „Ritterovci“, a poukazuje na její filosofické konvergence v oblasti praktické filosofie. V analýze vychází z několika nesporných afinit mezi Marquardovým a Blumenbergovým myšlenkovým světem: z návaznosti na gehlenovské pojetí (...) člověka jako deficitní (a kompenzující) bytosti, z oslavy polyteismu, ze společných obtíží s filosofií dějin, které je vedou ke kritice diskurzivní etiky (v duchu Nové levice). Předkládá a zdůvodňuje tezi, podle níž se zmínění Ritterovi žáci přiblížili k sobě navzájem – a současně i k Blumenbergovi – nejvíce poté, co byli nuceni reagovat nejen na studentské hnutí druhé poloviny 60. let, jež zpochybnilo demokratické struktury Spolkové republiky, ale i na neomarxismus, o nějž se studentské hnutí opíralo. Druhou část studie tvoří analýza liberálně konzervativní kritiky diskurzivní etiky, jejíž jádro představuje překvapivé Marquardovo čtení Descarta: Descartes dočasné a provizorní morálky je zde postaven proti Descartovi nepochybnému metodicky zajištěnému.

O objetivo deste texto é delimitar a relação entre educação e política na obra de John Locke, considerando as atribuições que o magistrado exerce. Nesse sentido, detalhar qual a função que o magistrado tem na manutenção dos direitos individuais e quais são as atribuições do poder legislativo e do poder executivo, torna-se necessário. Para tal intuito, iremos expor inicialmente a teoria lockeana da divisão dos poderes; em seguida, demonstraremos que o magistrado deve ser um indivíduo que elabora e execute as (...) leis imparcialmente; e, por fim, relacionar esta argumentação com seus escritos sobre educação. Por ser resultado de uma pesquisa qualitativa e de cunho filosófico empregamos a hermenêutica como metodologia. Consequentemente, o procedimento metodológico adotado foi a análise de texto. (shrink)

Die Idee, dass vor allem monetäre Anreize das Verhalten von Wirtschaftsakteuren in gewünschte Richtungen lenken und sogar dabei helfen können, durch Leistungssteigerung zusätzliche Wohlfahrtseffekte zu generieren, spielt in der politischen Ökonomie seit ihren Anfängen eine zentrale Rolle. Es spricht sogar einiges dafür, dass dieser Gedanke das verbindende Glied der Ökonomik als Gesellschaftstheorie im Gegensatz zu anderen gesellschaftstheoretischen Entwürfen ausmacht. Dennoch halte ich dieses Anreizargument aus normativer Perspektive für unterentwickelt, wie ich in Auseinandersetzung mit der Ökonomischen Ethik bzw. Ordnungsethik nach Karl (...) Homann und der Integrativen Wirtschaftsethik zeigen möchte. Weder gelingt es der Ordnungsethik nach Karl Homann, die Bedeutung von Anreizstrukturen hinreichend zu begründen, obwohl sie in Ansätzen wichtige Argumente formuliert. Noch gelingt es der Integrativen Wirtschaftsethik, die zentrale Rolle von Anreizstrukturen für die normative Theoriebildung überzeugend zurückzuweisen. Mir geht es nicht darum, den einen oder anderen wirtschaftsethischen Ansatz grundsätzlich zurückzuweisen, sondern vielmehr, auf Lücken in der Argumentation und sich daraus ergebende Forschungsfragen hinzuweisen. Vor diesem Hintergrund könnte es helfen, einen verwandten Diskurs aus der gegenwärtigen Gerechtigkeitstheorie in die Überlegungen mit einzubeziehen. Denn die grundlegende Idee der ökonomischen Gesellschaftstheorie einer Wohlfahrtssteigerung durch die gezielte Manipulation von Anreizstrukturen hat auch in der gegenwärtigen Gerechtigkeitstheorie ihre Wirkung entfaltet. In seiner Theorie der Gerechtigkeit hat John Rawls argumentiert, dass selbst Egalitaristen bestimmte Einkommensunterschiede zulassen müssen, wenn dadurch für Leistungsträgerinnen solche Anreize gesetzt werden, die gleichzeitig auch den Schlechtestgestellten zum Vorteil gereichen. Diese Argumentation ist von Gerald Cohen einer harschen Kritik ausgesetzt worden. Cohen behauptet, dass Rawls mit diesem Anreizargument seinen eigenen Egalitarismus unterläuft. Ich glaube, dass diese philosophische Diskussion des Anreizargumentes in der Gerechtigkeitstheorie für wirtschaftsethische Überlegungen relevant ist, obwohl sie innerhalb eines idealtheoretischen und egalitaristischen Bezugsrahmens geführt wird. Für diese Relevanz werde ich in vier Abschnitten argumentieren. In einem ersten Teil werde ich die Positionen der Ökonomischen Ethik von Karl Homann und der Integrativen Wirtschaftsethik von Peter Ulrich zur Rolle von Anreizen einführen und darlegen, warum ich beide Ansätze für normativ unterbestimmt halte. In einem zweiten Teil werde ich kurz die Argumentation von John Rawls und ausführlicher die Kritik von Gerald Cohen an dieser Position vorstellen. In einem dritten Teil werde ich einige Einwände gegen Cohen formulieren und die Notwendigkeit einer nichtidealen Theorie der Gerechtigkeit betonen. In einem vierten und abschließenden Teil werde ich vorschlagen, einen Teil der Wirtschaftsethik als nichtideale Gerechtigkeitstheorie zu verstehen und aus dieser Perspektive nur kurz andeuten, welche systematische Rolle dem Anreizargument zukommt.

Dans mon article, je soutiens qu'il existe une voie epistemique fiable qui mène de la connaissance des verités conceptuelles a celle des nécessites métaphysiques. Dans un premier temps, je montre que nous pouvons prétendre connaitre des vérites conceptuelles dans la mesure ou nous savons à quelles conditions nos termes (ou du moins un grand nombre d'entre eux) s'appliquent. Je défends notamment cette idée face a un argument récent que Williamson adresse a la conception épistémique de l'analyticite. Dans un second temps, (...) je montre que notre connaissance des vérités conceptuelles constitue un moyen fiable de connaitre des nécessités métaphysiques. En effet, de deux choses l'une : ou bien la connaissance conceptuelle conduit directement a la connaissance de nécessités métaphysiques ; ou bien, lorsque ce n'est pas le cas, nous pouvons du moins savoir qu'une telle inférence n'est pas permise, en vertu d une réflexion purement sémantique, « depuis notre fauteuil» (armchair). J'en conclus que la connaissance conceptuelle constitue un moyen sur d'acquérir des connaissances modales. (shrink)

Dogen Kigen (1200-1253) tritt uns in seinem Werk in vielfaltigen Aspekten entgegen: als Praktiker buddhistischer Lebensform und Experte fur Meditationstechniken, als Lehrer, um den sich Anhanger sammelten, als gebildeter Scholastiker, der sich bestens in buddhistischer Dogmatik auskannte, als Theoretiker, der diese Lehren und die mit ihnen verbundene Begrifflichkeit kritisch hinterfragte und auf seine Situation hin adaptierte, sowie als Neuerer, der traditionelle Konzepte auf eigenwillige Art interpretierte, und schliesslich als Dichter, der seine philosophischen Erkenntnisse auch in poetische Formen zu fassen wusste. (...) Um diese verschiedenen Facetten des Wirkens einzufangen, wird Dogens Werk aus unterschiedlichen Perspektiven und unter Einbeziehung verschiedener philosophischer Methoden betrachtet. Zusatzlich sind zwei seiner beruhmtesten Texte, Genjokoan und Bussho, in deutscher Neuubersetzung wiedergegeben. (shrink)

This article analyzes the angular spacing of the degree marks on the zodiac scale of the Antikythera mechanism and demonstrates that over the entire preserved 88° of the zodiac, the marks are systematically placed too close together to be consistent with a uniform distribution over 360°. Thus, in some other part of the zodiac scale (not preserved), the degree marks have been spaced farther apart. By contrast, the day marks on the Egyptian calendar scale are spaced uniformly, apart from minor (...) errors. A solar equation of center is apparent which rises by nearly 2.7° over the preserved portion of the zodiac. The placement of the degree marks indicates that, in the preserved portion of the zodiac, the Sun was considered to run at a uniform pace of about 30° per synodic month, which is consistent with the Sun’s speed in the fast zone of the Babylonian solar theory of System A.

While promoting population health has been the classic goal of public health practice and policy, in recent decades, new objectives in terms of autonomy and equality have been introduced. These different goals are analysed, and it is demonstrated how they may conflict severly in several ways, leaving serious unclarities both regarding the normative issue of what goal should be pursued by public health, what that implies in practical terms, and the descriptive issue of what goal that actually is pursued in (...) different contexts. A basic conflict of perspective is handled by integrating the ideas of public health striving for health-related autonomy and equality, resulting in a prioritarian oriented population approach to health-related autonomy. This integrated goal is demonstrated to constrain itself in several ways attractive from the point of view of the classic goal, but several serious problems remain. For this reason, a model where all of the three goals are integrated into one coherent structure where they can be assigned varying degrees of importance relative to the level of population health is described. It is argued that this model avoids the problems set out earlier, and is actually normatively preferable to the classic goal alone. It is furthermore argued that the model may be employed as a useful tool for descriptive ethics, as well as a vehicle for international harmonisation of public health policies. A number of practical implications regarding, e.g., the importance of respecting autonomy and the allocation of public health resources are noted, as are a battery of questions for further research.

One of the fundamental questions raised by Ruchkin, Grafman, Cameron, and Berndt's (Ruchkin et al.'s) interpretation of no distinct specialized neural networks for short-term storage buffers and long-term memory systems, is that of the link between perception and memory processes. In this framework, we take the opportunity in this commentary to discuss a specific working memory task involving percept formation, temporary retention, auditory imagery, and the attention-based maintenance of information, that is, the verbal transformation effect.

In response to Koplin and Wilkinson, I argue, first, that the uncertain clinical prospects of human-pig chimera based transplantation makes the reason to spend resources for clarifying whether such practice might imply serious ethical breach due to enhanced cognitive capacities of the chimeras rather weak. T he benefits of further pursuing this avenue of research is so uncertain, so that taking even very unclear risks of serious ethical breach (thus in need of clarification for justification of the research) is not (...) worth the price in terms of spent resources, and therefore only limited resources should be spent to clarify such risk before the project is abandoned due to unacceptable risks. Second, I argue that as there are some reason to pursue this avenue further (and thus investigate the risk in question), the analogy to the notion of halting all farming of larger animals for food does not hold up. The reason is that we do not need to probe any further any comparable risk to know that such farming practices should be halted. A fundamental underlying issue to the question discussed by Koplin and Wilkinson1 in this paper is formulated when they write: > We should therefore be confident that human-pig chimeras would lack morally relevant cognitive capacities before setting out to use them as a source of transplantable human organs. This leaves open the question of how confident …. (shrink)

No presente artigo serão discutidas algumas abordagens e explicações comparativas dedicadas à moderna teoria da linguagem, que podem ser encontradas tanto no filósofo neokantiano do símbolo Ernst Cassirer como nos linguistas estruturalistas Nikolaj Trubetzkoj e Roman Jakobson, que frequentemente se referem a Ferdinand de Saussure. Com esta finalidade, recorreremos a conceitualizações inovadoras usadas em comum no pensamento filosófico da primeira metade do século XX, tais como forma, estrutura, sistema, sinal, sentido ou significação e expressão, que determinam as respectivas teorias da (...) linguagem. Entre outras coisas, as evidências provam que certos novos princípios de pensamento e terminologias são avanços em diferentes disciplinas científicas e meios culturais, sem que seus descobridores ou representantes se refiram uns aos outros, ou mesmo que conheçam uns aos outros.

La modélisation financière moderne instrumente massivement des lois d'échelle pour la formalisation des fluctuations des marchés, à travers l'usage des processus aléatoires dans les équations de comportement des cours boursiers. D'abord implicites, présentes dans le mouvement brownien mais non perçues en tant que telles, les lois d'échelle sont réapparues explicitement comme enjeu de la modélisation depuis que les autorités de tutelle des marchés financiers ont attiré l'attention des établissements bancaires sur le problème du contrôle des risques, mal quantifiés par les (...) distributions gaussiennes classiques. On présente les éléments de ce débat, en adoptant comme fil conducteur la postérité des modèles fractals de Mandelbrot dans le sillage desquels s'inscrivent les principaux conflits de modélisation des variations boursières depuis les quarante dernières années. On montre que la question de l'existence de lois d'échelle renvoie à la question plus fondamentale de la nature du temps des marchés. (shrink)

The plant hormones auxin and brassinosteroid are both essential regulators of plant growth and known to influence both cell division and cell elongation in various developmental contexts. These physiological effects of auxin and brassinosteroid have been known for many years. Based on observations from external simultaneous application of both hormones to plant tissues, it has been suggested that they act in an interdependent and possibly synergistic manner. Recent work in the model plant Arabidopsis thaliana suggests that, at the molecular level, (...) auxin–brassinosteroid synergism manifests itself in the regulation of the expression of common target genes. However, whether this reflects genuine hormone pathway‐dependent crosstalk modulation of the transcription machinery or rather indirect effects of hormone action on other cellular activities, such as hormone biosynthesis or the polar transport of auxin, is not entirely clear. This article reviews the evidence for transcriptional crosstalk between auxin and brassinosteroid and its molecular basis. BioEssays 29:1115–1123, 2007. © 2007 Wiley Periodicals, Inc. (shrink)
