This article reviews experimental evidence for a specific sensorimotor function which can be dissociated from higher level representations of space. It attempts to delineate this function on the basis of results obtained by psychophysical experiments performed with brain damaged and healthy subjects. Eye and hand movement control exhibit automatic features, such that they are incompatible with conscious control. In addition, they rely on a reference frame different from the one used by conscious perception. Neuropsychological cases provide a strong support for (...) this specific motor representation of space, which can be spared in patients with lesions of primary sensory systems who have lost conscious perception of visual, tactile or proprioceptive stimuli. Observation of these patients also showed that their motor behavior can be ''attracted'' by a goal only under specific conditions, that is, when the response is immediate and when no cognitive representation of this goal is elaborated at the same time. Beyond the issue of the dissociation between an implicit motor representation and more cognitive processing of spatial information, the issue of the interaction between these two systems is thus a matter of interest. It is suggested that the conscious, cognitive representation of a stimulus can contaminate or override the short-lived motor representation, but no reciprocal influence seem to occur. The interaction observed in patients can also be investigated in normals. The literature provides examples of interaction between sensorimotor and cognitive framing of space, which confirm that immediate action is not mediated by the same system as delayed action, and that elaborating a categorial representation of the action goal prevents the expression of the short-lived sensorimotor representation. It is concluded that action can be controlled by a sensory system which is specialized for on-line processing of relevant goal characteristics. The temporal constraints of this system are such that it can affect the action before a full sensory analysis of this goal has been completed. The performance obtained on the basis of this spatial sensory processing suggests that short-lived motor representations may rather be considered as real ''presentation'' of the action world, which share its metric properties.

A visual analogue, two-route model of somatosensory processing is advanced in this commentary. Touch for perception is seen as separate from, although interconnected with, touch for action. Separate modules are additionally proposed for internal (body) and external (object-related) somatosensation. Here we ask whether dissociation (divide) guarantees better efficiency (impera) in terms of the heuristic model within the somatosensory modality and across modalities.

La publication du Journal du Concile de l’ambassadeur P. Poswick est l’occasion de rappeler quelques questions majeures de Vatican II dans le traitement desquelles trois évêques belges se sont particulièrement illustrés. Ce rapide parcours permet de dépasser les oppositions émises récemment à propos du Concile entre « l’événement et le texte » de même qu’entre « la discontinuité et la continuité ». On constate en effet que le témoignage des acteurs est indispensable pour la compréhension des textes et que les (...) avancées du Concile permettent une meilleure compréhension de la tradition.

Le présent défi pour l’Église, c’est à la fois celui de la mondialisation et d’un pluralisme religieux croissant, qu’il s’agisse des grandes religions ou des nouvelles religiosités. Mais elle doit affronter aussi un indifférentisme religieux qui peut être l’envers d’un combat passionné pour l’homme. Face à ces défis, il faut tenir compte d’un nouveau paradigme théologique, celui d’un pluralisme religieux de principe qui s’interroge sur la signification de la pluralité des religions à l’intérieur du dessein de Dieu. Ce nouveau paradigme (...) nous invite à instaurer un nouveau rapport à la vérité en théologie. Et c’est en allant jusqu’au bout du paradoxe christologique que l’on peut désigner le christianisme comme une religion essentiellement dialogale. Comme l’œcuménisme, le dialogue interreligieux doit être une dimension de toute la théologie. La théologie des religions tend alors à devenir une théologie interreligieuse qui manifeste la fécondation mutuelle des religions dans notre discours sur Dieu et sur le salut de l’homme. (shrink)

The rise in interdisciplinary scholarship between philosophy and theology has produced a number of critiques of historical biblical criticism (HBC) by philosophers of religion. Some dialogue has resulted, but these critiques have gone largely unnoticed by historical critical scholars. This article argues that two such critiques of HBC, offered by Plantinga and Stump, are undermined by faulty presuppositions on the philosophers' part regarding the nature and value of HBC and misunderstandings of the nature of the ancient texts on which the (...) discipline of HBC focuses.

Il Parmenide _phusikos_ e il meccanismo di Antikitera: Risposta alle osservazioni di N.-L. Cordero.

Philosophy is often taken to be something that is always possible, so that everyone is fully entitled sketching a ‘philosophy’ of his/her own. Nevertheless, it is widely assumed that philosophy began in Miletus with Thales. But it is equally well known that the Presocratics remained unaware of being philosophers, and therefore could not even have wanted to be identified that way. These three points are not mutually compatible. So, what lies behind them? What is escaping our attention when we state (...) them? Probably an event in Plato’s life that has too often gone unnoticed: the key role he played in giving form and substance to philosophy, and in getting it to take root once and for all. Failure to acknowledge how, when, and on whose initiative philosophy came to occupy a very important place in Western culture and education for two and a half millennia; not including a note on this process in biographies of Plato; and overlooking another key event that probably occurred about 350-45 BC - these are just some of the unwelcome effects linked to the usual silence about the period in which philosophy took form.

Philosophical considerations as well as several recent studies from neurophysiology, neuropsychology, and psychophysics converged in showing that the peripersonal space is structured in a body-centred manner and represented through integrated sensory inputs. Multisensory representations may deserve the function of coding peripersonal space for avoiding or interacting with objects. Neuropsychological evidence is reviewed for dynamic interactions between space representations and action execution, as revealed by the behavioural effects that the use of a tool, as a physical extension of the reachable space, (...) produces on visual–tactile extinction. In particular, tool-use transiently modifies action space representation in a functionally effective way. The possibility is discussed that the investigation of multisensory space representations for action provides an empirical way to consider in its specificity pre-reflexive self-consciousness by considering the intertwining of self-relatedness and object-directness of spatial experience shaped by multisensory and sensorimotor integrations.

Este artigo trata da relação entre Comunicação e Filosofia ao apontar alguns momentos em que a comunicação foi objeto de reflexão filosófica. A Comunicação instituída como área do conhecimento é algo muito recente e pertence à história do século XX, embora a comunicação como fenômeno seja tão antiga quanto à própria humanidade. Já a comunicação como tema discutido pelo pensamento ocidental remonta aos filósofos gregos, como Platão e Aristóteles, e contemporaneamente a pensadores como Nietzsche, Bergson, Foucault e Hannh Arendt, dentre (...) outros mais óbvios. O objetivo deste artigo é apontar dentro da História da Filosofia ocidental alguns momentos em que diversos filósofos trataram do tema da comunicação, e assim sugerir um aporte para uma reflexão interdisciplinar sobre temas ligados a comunicação.
