In cognitive neuroscience, dissociating the brain networks that ing—has thus become one of the best empirical situations subtend conscious and nonconscious memories constitutes a through which to study the mechanisms of implicit learning, very complex issue, both conceptually and methodologically.

Using positron emission tomography (PET) and regional cerebral blood flow (rCBF) measurements, we investigated the cerebral correlates of consciousness in a sequence learning task through a novel application of the Process Dissociation Procedure, a behavioral paradigm that makes it possible to separately assess conscious and unconscious contributions to performance. Results show that the metabolic response in the anterior cingulate / mesial prefrontal cortex (ACC / MPFC) is exclusively and specifically correlated with the explicit component of performance during recollection of a (...) learned sequence. This suggests a significant role for the ACC / MPFC in the explicit processing of sequential material.  2003 Elsevier Science B.V. All rights reserved. (shrink)

Presenting a fascinating analysis of the idea of what can't be said, this book ascertains whether the notion of there being a truth, or a state of affairs, or knowledge that can't be expressed linguistically is a coherent notion. The author distinguishes different senses in which it might be said that something can't be said. The first part looks at the question of whether ineffability is a coherent idea. Part two evaluates two families of arguments regarding whether ineffable states of (...) affairs actually exist: the argument from mysticism and the argument from epistemic boundedness. Part three looks more closely at the relation between mystic and non-mystic stances. In the fourth and final part the author distinguishes five qualitatively different types of ineffability. _Ineffability and Philosophy_ is a significant contribution to this area of research and will be essential reading for philosophers and those researching and studying the philosophy of language.

The book generalises earlier theories of belief change to cover all kinds of changes of sets by sets. The principal focus is still on changes of belief sets in response to new evidence, but the formal theory extends to all domains with a closure operation and a preference structure including, for example, systems of action. Contraction is the key notion; all other changes can be defined. Various new applications of the theory are outlined. A sentential version of contraction, subtraction, is (...) proposed as a formal counterpart to 'except'-locutions in natural language. Connections are emphasised with other areas at the interface between philosophical logic and artificial intelligence such as reasoning from default assumptions or from inconsistent premises. A relation of merge inference is proposed as a means of retrieving maximal but nontrivial information from inconsistent premises. Merge inference respects certain anti-Boolean intuitions while avoiding a revision of classical logic. (shrink)

The philosophy problem of identity and the related problem of change go back to the ancient Greek philosophers and fascinated later figures including Leibniz, Locke and Hume. Heraclitus argued that one could not swim in the same river twice because new waters were ever flowing in. When is a river not the same river? If one removes one plank at a time when is a ship no longer a ship? What is the basic nature of identity and persistence? This book (...) introduces and asseses the philosophical puzzles posed by things persisting through time. Beginning with essential historical background to the problem it explores the following key topics and debates: mereology and identity, including 'Leibniz's Law' the constitution view of identity the 'relative identity' argument concerning identity temporary identity four-dimensionalism, counterpart and mulitiple counterpart theory supervenience the problem of temporary intrinsics the necessity of identity presentism ontological and epistemological criteria for persistence and the difference between them. Including chapter summaries, annotated further reading and a glossary this book is essential reading for anyone seeking a clear and informative introduction to and assessement of the metaphysics of identity.

The Jordan decomposition theorem states that every function $f \colon \, [0,1] \to \mathbb {R}$ of bounded variation can be written as the difference of two non-decreasing functions. Combining this fact with a result of Lebesgue, every function of bounded variation is differentiable almost everywhere in the sense of Lebesgue measure. We analyze the strength of these theorems in the setting of reverse mathematics. Over $\mathsf {RCA}_{0}$, a stronger version of Jordan’s result where all functions are continuous is equivalent to (...) $\mathsf {ACA}_0$, while the version stated is equivalent to ${\textsf {WKL}}_{0}$. The result that every function on $[0,1]$ of bounded variation is almost everywhere differentiable is equivalent to ${\textsf {WWKL}}_{0}$. To state this equivalence in a meaningful way, we develop a theory of Martin–Löf randomness over $\mathsf {RCA}_0$. (shrink)

In this article, we first review the development of clinical ethics in pediatrics in the United States. We report that, over the last 40 years, most children’s hospitals have ethics committees but that those committees are rarely consulted. We speculate that the reasons for the paucity of ethics consults might be because ethical dilemmas are aired in other venues. The role of the ethics consultant, then, might be to shape the institutional climate and create safe spaces for the discussion of (...) difficult and sometimes contentious issues. Finally, we report how pediatric clinical ethics has evolved differently in a number of other countries around the world. (shrink)

La formule " plénitude ontologique du vide " signifie que le vide n'est pas un néant, un rien ou une absence définitive mais, au contraire, l'affirmation en son autosuffisance de la présence à l'état pur. Le vide est plein de la présence pure, mieux il s'identifie à elle. De l'atomisme antique à la révolution scientifique en passant par la Renaissance, de Démocrite à Newton, d'Aristote à Descartes en tant que ses plus éminents adversaires, le vide n'a cessé de hanter tant (...) le champ de la métaphysique que celui de la science, celui de l'expérience comme celui de l'imaginaire. Après avoir tenté de l'expulser de la physique au moyen de la notion d'éther, la cosmologie contemporaine redécouvre le rôle essentiel du vide dans le devenir et peut-être l'origine de l'univers. Aujourd'hui, c'est au tour de la métaphysique de soupeser à nouveaux frais le poids du vide dans le cadre de la problématique qui lui est propre. Après un siècle de dépassement, de déconstruction et autre célébration de la fin de la métaphysique, l'intention est de démontrer ici que, loin d'être oublieuse de la question de l'être, elle a pensé celle-ci avec une portée et une acuité sans égales.

Le développement conjoint, au cours du XVIIIe siècle, de la méthode historico-critique et du perspectivisme est à l'origine d'une tension nouvelle dans le traitement de l'histoire de la philosophie. L'article analyse brièvement quelques réactions, plus ou moins radicales, à cette configuration féconde. Zeller, Dilthey, Yorck, Nietzsche, Weber, Heidegger, Rorty, sont les principaux témoins. Il est aussi suggéré que la « doxographie », en dépit de la réputation détestable dont elle jouit, aussi bien chez les historiens que chez les philosophes, demeure (...) une composante importante de toute réflexion sur la relation de la philosophie à son passé. The joint development, in the course of the XVIIIth century, of the historico-critical method on the one hand and of a self-conscious perspectivism on the other hand, created a new tension in the handling of the history of philosophy. In the following, I sketch some characteristic ways, hard or more compromising, of dealing with this lasting and, I suggest, productive tension. Zeller, Dilthey, Yorck, Nietzsche, Weber, Heidegger, Rorty are my main witnesses. In the wake of an analysis made by M. Frede, I also suggest, in the light of this tension, that « doxography », despite the detestable reputation the genre has among philosophers and historians of philosophy alike, remains an important component of any reflexion about the relationship between philosophy and its past.

Abstract Fodor defines epistemic boundedness as a condition wherein there are epistemi?cally significant constraints on the beliefs that a mind is capable of entertaining. He discusses a type of (epistemic) boundedness wherein a hypothesis cannot be entertained because it is inexpressible in terms of the mind's stock of concepts. In addition to this semantic boundedness, I describe a number of different sources of boundedness having to do with syntactic, abductive, and implementational limitations. I also discuss the similarities and differences between (...) individual and social limitations on our epistemic possibilities. (shrink)

It is widely recognized that computational theories of learning must posit the existence of a priori constraints on hypothesis selection. The present article surveys the theoretical options available for modelling the dynamic process whereby the constraints have their effect. According to the 'simplicity' theory (exemplified by Fodor's treatment), hypotheses are preference-ordered in terms of their syntactic or semantic properties. It is argued that the same explanatory power can be obtained with a weaker (hence better) theory, the 'minimalist' theory, which dispenses (...) with the preference ordering. According to the 'finitistic' theory, the learner is capable of generating only finitely many hypotheses for evaluation. Chomsky maintains that the occurrence of errorless learning in language acquisition necessitates a finististic explanation. Once again, there is a weaker theory that explains the same data. Finally, Goodman's argument to the effect that there cannot be a computational theory of learning is examined and rejected. (shrink)

Hegel's often-echoed verdict on the apolitical character of philosophy in the Hellenistic age is challenged in this collection of essays, originally presented at the sixth meeting of the Symposium Hellenisticum. An international team of leading scholars reveals a vigorous intellectual scene of great diversity: analyses of political leadership and the Roman constitution in Aristotelian terms; Cynic repudiation of the polis - but accommodation with its rulers; Stoic and Epicurean theories of justice as the foundation of society; Cicero's moral critique of (...) the traditional political pursuit of glory. The volume as a whole offers a comprehensive guide to the main currents of social and political philosophy in a period of increasing interest to classicists, philosophers and cultural and intellectual historians.

In Nietzsche and Zen: Self-Overcoming without a Self, André van der Braak juxtaposes Nietzsche with four influential representatives of the Buddhist Zen tradition: Nagarjuna, Linji, Dogen, and Nishitani. In doing so, he reveals Nietzschean philosophy as a philosophy of continuous self-overcoming, in which even the notion of "self" is overcome, and allows a greater understanding of Nietzsche through the lens of Zen and vice versa. This treatment will be useful to Nietzsche scholars, continental philosophers, and comparative philosophers.

Analisaremos o comentário produzido por Leo Strauss a partir dos textos de Maquiavel no livro Thoughts on Machiavelli. Com base na crítica do método de leitura e escrita dos textos filosóficos de Strauss, podemos perceber que a operação interpretativa de Strauss consiste na construção de uma nova figuração do velho maquiavelismo que assaltou a obra de Maquiavel desde que passou a ser censurada pelos padres. A enunciação da tese de que o ensinamento de Maquiavel é diabólico consiste apenas no traço (...) mais superficial e evidente da interpretação teológica de Strauss, pois sob a sua nova figuração do “maquiavelismo” podemos ver ao fundo o seu projeto de destruição da filosofia moderna para insinuar uma certa e determinada filosofia contemporânea como se fosse o reestabelecimento da filosofia política clássica.
