As reconstruções racionais da teoria do agir comunicativo exigem um procedimento que coaduna três tipos de ações: comunicativas, instrumentais e estratégicas. A desconfiança em torno das escolhas racionais recai sobre o tipo de agir estratégico. A perspectiva cognitivista alimenta um carácter lógico de tipo meio-fim. Existe o risco de o sujeito limitar-se simplesmente ao autointeresse individual, pois as escolhas podem obedecer a determinados cálculos egocêntricos. Em uma sociedade individualista, as motivações subjetivas freiam escolhas de tipo universal. No caso da educação, (...) os cálculos racionais supõem uma orientação que exclui conteúdos de caráter obrigatório. Isso acontece, por exemplo, com os temas de história e cultura afro-brasileira e indígena, exigência presente nas Leis de Diretrizes e Bases da Educação nacional. O modelo monolíngue contrasta com a perspectiva reconstrutiva de Habermas. Para entender essas questões, o texto retoma o modelo de Lakatos para, então, superar os riscos da racionalidade estratégica. (shrink)

A hard difficulty in Astrobiology is the precise definition of what life is. All living beings have a cellular structure, so it is not possible to have a broader concept of life hence the search for extraterrestrial life is restricted to extraterrestrial cells. Earth is an astronomical rarity because it is difficult for a planet to present liquid water on the surface. Two antagonistic bioethical principles arise: planetary protection and terraforming. Planetary protection is based on the fear of interplanetary cross-infection (...) and possible ecological damages caused by alien living beings. Terraforming is the intention of modifying the environmental conditions of the neighbouring planets in such a way that human colonisation would be possible. The synthesis of this antagonism is ecopoiesis, a concept related to the creation of new ecosystems in other planets. Since all the multicellular biodiversity requires oxygen to survive, only extremophile microorganisms could survive in other planets. So, it could be carried out a simulation of a meteorite by taking to other planets portions of the terrestrial permafrost, or ocean or soil, so that if a single species could grow, a new ecosystem would start, as well as a new Natural History. As a conclusion, ecopoiesis should be the bioethical principle to guide practices and research in Astrobiology. (shrink)

Cet ouvrage se penche sur la question des transformations à l’œuvre dans les traditions rituelles des religions méditerranéennes antiques, avec une attention particulière portée aux acteurs à l’origine de ces changements ainsi qu’aux émotions suscitées. Plusieurs contributions sont issues de communications présentées dans le panel « agency » du colloque « Ritual Dynamics and the Science of Ritual », organisé à Heidelberg en 2008. Je résume ici les contributions portant sur le monde grec. L’an...

L’ouvrage de P. Ismard (P.I.) cherche à comprendre « le poids de l’événement que représente le procès de Socrate dans la mémoire occidentale » (p. 11). Cet objectif repose sur trois angles d’approche : il s’agit de saisir les enjeux du procès comme tel, d’utiliser cet « événement » comme clé d’analyse des institutions athéniennes contemporaines du procès, et d’étudier la réception du procès aux époques ultérieures. L’analyse est structurée autour de neuf chapitres, dans un langage fluide et a...

Derrière un titre assez sobre, la structure de l’ouvrage de R. Gagné (R.G.) permet d’entrevoir son originalité. Loin de se contenter d’une brève circonscription du concept de faute ancestrale dans l’introduction, l’A. consacre les deux premiers chapitres à la réception et à la réinterprétation de cette notion après l’Antiquité. Il cherche ainsi à montrer par quels filtres successifs a transité la notion avant d’arriver jusqu’à nous. Ce n’est qu’après un exposé assez érudit sur les nombreux au...

The notion of individualised evidence holds the key to solve the puzzle of statistical evidence, but there’s still no consensus on how exactly to define it. To make progress on the problem, epistemologists have proposed various accounts of individualised evidence in terms of causal or modal anti-luck conditions on knowledge like appropriate causation, sensitivity and safety. In this paper, I show that each of these fails as satisfactory anti-luck condition, and that such failure lends abductive support to the following conclusion: (...) once the familiar anti-luck intuition on knowledge is extended to individualised evidence, no single causal or modal anti-luck condition on knowledge can succeed as the right anti-luck condition on individualised evidence. This conclusion casts serious doubts on the fruitfulness of the move from anti-luck conditions on knowledge to anti-luck conditions on individualised evidence. I expand on these doubts and point out further aspects where epistemology and the law come apart: epistemic anti- luck conditions on knowledge do not adequately characterise the legal notion of individualised evidence.

The article considers the nature of series as a narrative, focusing especially on its chronotope, i.e. its spatiotemporal coordinates. The concept of chronotope can be applied at at least two different levels of the interpretation of a narrative: the real world of reception and the expressive form of narration. The impact of series entails both aspects. It is for this reason that series, once on television then on the internet, represented a revolutionary turn in the modern experience of storytelling. Series (...) are therefore bound to the progressive spread of a new form of sociality known as a digital “total mobilisation”. Since the era of TV series up to the emergence of web series, seriality has been able to regulate the increase of interaction in the use of visual devices. Series play the role of a dietetical regulator, which designs the spectators’ attention. An artistic, i.e. experimental, exploitation of this new form of storytelling is possible when one considers the emergence of a new narrative genre, which we propose to call the “short form”.

Recent epistemology has witnessed a substantial opposition between two competing approaches to capturing the notion of non-accidentality in the analysis of knowledge: the explanationist and the modalist. According to the latest advocates of the former, S knows that p if and only if S believes that p because p is true. According to champions of the latter, S knows that p if and only if S's belief that p is true in a relevant set of possible worlds. Because Bogardus and (...) Perrin's explanationism promises to deliver a plausible analysis of knowledge without any need for modal notions, it is an elegant proposal with prima facie appeal. However, such version of explanationism ultimately does not live up to its promises: in this paper, I raise some objections to their explanationist analysis of knowledge while showing that modalism is in much better shape than they think. In particular, I argue that their explanationist condition generates the wrong results in Gettier cases and fake-barn cases. I also offer and defend a novel version of modalism: I introduce a refined safety condition which is shown to successfully handle the same Gettier cases that beset Bogardus and Perrin's version of explanationism. The paper concludes with a reassessment of the explanationist's initial ambition to provide an analysis of knowledge without modal notions. The upshot will be that even if the prospects for such analysis remain dim, our money should be on the modalist, not the explanationist. (shrink)
