Social behaviors rely on the coordination of multiple effectors within one’s own body as well as between the interacting bodies. However, little is known about how coupling at the interpersonal level impacts coordination among body parts at the intrapersonal level, especially in ecological, complex, situations. Here, we perturbed interpersonal sensorimotor communication in violin players of an orchestra and investigated how this impacted musicians’ intrapersonal movements coordination. More precisely, first section violinists were asked to turn their back to the conductor and (...) to face the second section of violinists, who still faced the conductor. Motion capture of head and bow kinematics showed that altering the usual interpersonal coupling scheme increased intrapersonal coordination. Our perturbation also induced smaller yet more complex head movements, which spanned multiple, faster timescales that closely matched the metrical levels of the musical score. Importantly, perturbation differentially increased intrapersonal coordination across these timescales. We interpret this behavioral shift as a sensorimotor strategy that exploits periodical movements to effectively tune sensory processing in time and allows coping with the disruption in the interpersonal coupling scheme. As such, head movements, which are usually deemed to fulfill communicative functions, may possibly be adapted to help regulate own performance in time. (shrink)

Strategies purporting to determine the meaning of inner states of belief-content in terms of their inferential role usually assume the inner structure of the human inferential competence to be that of first order logic plus identity. Considerations of computational complexity and cumbersomeness of representation tend to undermine the plausibility of combining such strategies with this assumption. In this paper I contend that appealing to rules of default reasoning won’t make things turn out any better for the inferential role functionalist.

Secrets of Infinity examines infinity as it has been studied since antiquity in an entertaining and practical way.

European scholars discuss Leo Strauss as a major figure in the history of philosophy. This volume presents, for the first time in English, the approaches to Leo Strauss being pursued by European scholars in Spain, Italy, and Germany. Whereas the traditions of Strauss interpretation have, until recently, focused on issues of interest to political science and, to a lesser extent, religious studies, this collection makes a powerful contribution to the recent philosophical consideration of Strauss. Each essay treats a unique thread (...) emerging from the tapestry of Straussian thought, illustrating Strauss’s thinking on the reading of ancient texts and on the relationship between philosophy and politics. In doing so, Strauss is placed squarely and uncompromisingly within the history of philosophy, in conversation with a large range of philosophical figures. “This is a really wonderful volume, a compelling narrative of Strauss as a reader of philosophical texts who both originated a new way of philosophical exploration as well as freely responded to philosophical and historical circumstances of his time.” — Jeffrey A. Bernstein, College of Holy Cross. (shrink)

INCONTINENCE, HONOURING SUNK COSTS AND RATIONALITY According to a basic principle of rationality, the decision to engage in a course of action should be determined solely by the analysis of its consequences. Thus, considerations associated with previous use of resources should have no bearing on an agent’s decision-making process. Frequently, however, agents persist carrying on an activity they themselves judge to be nonoptimal under the circumstances because they have already allocated resources to that activity. When this is the case, agents (...) are said to be honouring sunk costs. Honouring sunk costs is thus typically viewed as irrational economic behaviour. Two striking findings of the psychological literature on the sunk cost effect are that it is, in general, not lessened by having taken previously courses in economics, and that agents who did take such courses and that do honour sunk costs seem to be frequently aware of a cognitive dissonance in their behaviour. Davidson’s account of the possibility conditions of incontinent action renders continent action materially unfeasible. The very idea of incontinent action becomes thus a hollow one. I’ll present an alternative description of these possibility conditions that renders continent action materially feasible, and both, continent and incontinent action, cognitively plausible. In a nutshell, my proposal rests upon the drawing of an essential cognitive contrast between explicit processes of deliberative reasoning and lower level heuristic procedures. I conclude the paper arguing that my redescription of incontinent action accounts for the above mentioned cognitive dissonance effect better than the alternatives and that viewing at least an important subset of behaviours of honouring sunk costs as incontinent actions will enable us to consider them as peculiar manifestations of a more general and meaningful pattern in human behaviour.

Vroeger leek de keus simpel, meent neuroloog Antonio Damasio: je liet je meevoeren in de maalstroom van het modernisme of trok je terug in een klassiek Arcadië. Maar nu kunnen we ons niet langer aan de maalstroom onttrekken. De digitale revolutie biedt ons allerlei gemakken en voordelen, maar heeft ook mogelijk desastreuze gevolgen voor onze moraliteit. In plaats van ons in een Arcadië terug te trekken, moeten we ons daartegen teweer stellen.

Em tempos de cultura digital, observa-se o acesso a uma quantidade incomensurável de informações sem que sejam feitas relações que poderiam transformá-las em conceitos. Uma vez que prevalece o uso instrumental de tais informações, arrefece concomitantemente a postura ética que o questiona. É nesse contexto que o professor ocupa um posto decisivo no que diz respeito à organização e à discussão de tais informações com seus alunos. Este artigo tem como objetivo argumentar que a postura de Pedro Goergen como educador (...) oferta aos alunos um tipo de relação que faz com que a própria figura do professor seja eticamente ressignificada nessa sociedade de cultura digital.

"All the chapters in this volume somehow and quite diversely, directly or indirectly, address the relation of Wittgenstein's philosophy, or at least of Wittgenstein- inspired philosophical thought, with scepticism, here generally envisaged as a many-sided tradition and not as a uniform and once for all established theoretical posture.".
