Following a short summary of the free-will problem as it applies to the question of God’s prescience, I offer a detailed analysis and critique of Plantinga’s and Maritain’s efforts to reconcile these two notions. I end by arguing that a process interpretation, similar to that of Whitehead, is also incapable of providing the needed reconciliation.

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.

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

What did the early Greek philosophers think about animals and their lives? How did they view plants? And, ultimately, what type of relationship did they envisage between all sorts of living beings? On these topics there is evidence of a prolonged investigation by several Presocratics. However, scholarship has paid little attention to these issues and to the surprisingly "modern" development they received in Presocratics' doctrines. This book fills this lacuna through a detailed (and largely unprecedented) analysis of the extant evidence. (...) The volume includes also the first extensive collection of the ancient sources pertaining to living beings and life in early Greek philosophy, organized chronologically and thematically. (shrink)

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.

In Plato’s Laws several passages have been clearly conceived of as preambles. The most extended, and prominent, is the one we find at the beginnings of Book five. It amounts to a complicate tour de force, not easy to be accounted for.What surfaced during the present investigation is a meandrical line of thought which ends with the unexpected adoption of a proto-utilitarianist point of view. This turn is not only interesting per se, since it implies that the author fully acknowledges (...) the role of subjective evaluations that may well ignore the ontological hierarchy between gods-souls-bodies as well as the force of persuasion a wise legislator avails of.

To teach catholic religion to Italian pupils from 6 to 18 years may not be a very gratifying experience. However, a new option is worth being considered, I submit, namely to devote half of the time to a very simple way of doing philosophy, i.e. to offer pupils attention to their ideas, hopes and problems by means of whole hours devoted to free exchanges with them and among them. Why the teachers of Religion instead of their colleagues, no matter which? (...) It should be clear that this is a mere accident: too often, other teachers are (wrongly, but firmly) convinced that they lack the time needed in order to consider such an opportunity. (shrink)

Was Parmenides a distinguished ‘astronomer’ and ‘biologist’ other than the great ‘philosopher’ he has been unanimously considered from the times of Plato onwards? Many admirers of the ‘philosopher’ are not just refractory to consider this possibility: they simply ignore what Parmenides was able to discover in the additional domains I have just mentioned. But he was great as an ‘astronomer’ and a ‘biologist’ too, probably not less great than as a ‘philosopher’.The aim of this paper is to supply the basic (...) information about Parmenides' achievements in these domains, that were of the highest order, I presume.Presocratic Philosophy and ‟Natural Theology”.

Durante il V secolo AC Parmenide ebbe molti e qualificati lettori, tra cui Zenone, Empedocle, Anassagora, Leucippo, Melisso, Protagora, Gorgia, Ippia. Tre di loro hanno cercato di fare molto di più di quello che è stato in grado di fare lui con l' ‘esercizio deduttivo’ che incontriamo in 28B8.1-33, e ci sono riusciti. In effetti, che si siano sforzati di superare l'elevato standard già raggiunto da Parmenide nell'invenzione dei passaggi strettamente deduttivi è sostanzialmente fuori discussione. Il mio articolo è dedicato (...) a rendere conto degli ambiziosi obiettivi che Zenone, Melisso e Gorgia raggiunsero, ciascuno in modi molto differenti. (shrink)

It is no surprise if a good quality communication unit succeeds in seizing the attention of the intended audience (or readership) and is able to let people see precisely what the author wanted them to see, while avoiding that the average addressee become aware of what the author wants to convey in an almost subliminal way. In this respect Plato is no exception. Nevertheless the study of these resources, far from having been somewhat systematic, still is largely neglected, and only (...) a minority of commentators find it important to pay head to the communicational strategies which are at work in Plato's dialogues. It will be argued that the shades of meaning and the contextualization of thought (a) systematically grant to Plato ample room for affecting the way a reader comes to perceive his points of doctrine and (b) often let him convey a biased perception of his arguments.The paper includes an outline of the already longstanding debate on these matters, a case study (Memo 80–82), and a sketchy typology of how the literary working-out is able to affect the reader's perception of the line of thought, esp. within the aporetic dialogues.

A further step in Pylyshyn's discontinuity thesis is to examine the penetrability of haptic (tactual-kinesthetic) perception. The study of the perception of orientation and the “oblique effect” (lower performance in oblique orientations than in vertical–horizontal orientations) in the visual and haptic modalities allows this question to be discussed. We suggest that part of the visual process generating the visual oblique effect is cognitively impenetrable, whereas all haptic processes generating the haptic oblique effect are cognitively penetrable.

Dienes & Perner's (D&P's) target articles proposes an analysis of explicit knowledge based on a progressive transformation of implicit into explicit products, applying this gradient to different aspects of knowledge that can be represented. The goal is to integrate a philosophical concept of knowledge with relevant psychophysical and neuropsychological data. D&P seem to fill an impressive portion of the gap between these two areas. We focus on two examples where a full synthesis of theoretical and empirical data seems difficult to (...) establish and would require further refinement of the model: action representation and the closely related consciousness of action, which is in turn related to self-consciousness.

Some data concerning visual illusions are hardly compatible with the perception–action model, assuming that only the perception system is influenced by visual context. The planning–control dichotomy offers an alternative that better accounts for some controversy in experimental data. We tested the two models by submitting the patient I. G. to the induced Roelofs effect. The similitude of the results of I. G. and control subjects favoured Glover's model, which, however, presents a paradox that needs to be clarified.

Is there any ecological purpose in assuming that perception for action exists only through a global array of energy? Unlike Stoffregen & Bardy, who assume that behavior consists of movements, we would argue that behavior consists of a stable coupling between perception and action achieved through experience in an adaptive context. Determining target position in an aiming manual task and temporal control of impact movement illustrate that patterns of energy used for action are task-dependent.
