We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of combining prototypical concepts, an open problem in the fields of AI and cognitive modelling. Our logic extends the logic of typicality ALC + TR, based on the notion of rational closure, by inclusions p :: T(C) v D (“we have probability p that typical Cs are Ds”), coming from the distributed semantics of probabilistic Description Logics. Additionally, it embeds a set of cognitive heuristics for concept (...) combination. We show that the complexity of reasoning in our logic is EXPTIME-complete as in ALC. (shrink)

The paper introduces an extension of the proposal according to which conceptual representations in cognitive agents should be intended as heterogeneous proxytypes. The main contribution of this paper is in that it details how to reconcile, under a heterogeneous representational perspective, different theories of typicality about conceptual representation and reasoning. In particular, it provides a novel theoretical hypothesis - as well as a novel categorization algorithm called DELTA - showing how to integrate the representational and reasoning assumptions of the theory-theory (...) of concepts with the those ascribed to the prototype and exemplars-based theories.

In his famous 1982 paper, Allen Newell [22, 23] introduced the notion of knowledge level to indicate a level of analysis, and prediction, of the rational behavior of a cognitive arti cial agent. This analysis concerns the investigation about the availability of the agent knowledge, in order to pursue its own goals, and is based on the so-called Rationality Principle (an assumption according to which "an agent will use the knowledge it has of its environment to achieve its goals" [22, (...) p. 17]. By using the Newell's own words: "To treat a system at the knowledge level is to treat it as having some knowledge, some goals, and believing it will do whatever is within its power to attain its goals, in so far as its knowledge indicates" [22, p. 13]. In the last decades, the importance of the knowledge level has been historically and system- atically downsized by the research area in cognitive architectures (CAs), whose interests have been mainly focused on the analysis and the development of mechanisms and the processes governing human and (arti cial) cognition. The knowledge level in CAs, however, represents a crucial level of analysis for the development of such arti cial general systems and therefore deserves greater research attention [17]. In the following, we will discuss areas of broad agree- ment and outline the main problematic aspects that should be faced within a Common Model of Cognition [12]. Such aspects, departing from an analysis at the knowledge level, also clearly impact both lower (e.g. representational) and higher (e.g. social) levels. (shrink)

O presente artigo busca apresentar a perspectiva educativa de Paulo Freire a partir da relação com o personalismo de Emmanuel Mounier. O ponto de destaque em tal relação é a visão da construção de uma educação pautada na autonomia e na abertura à comunidade, uma educação não meramente técnica, mas que seja capaz de preparar o ser humano para o fazer e para o ser. Esta educação, segundo Paulo Freire, não pode esquecer a importância do Protagonismo do educando no processo (...) educativo, deve ser fundamentada no diálogo e sempre aberta a refletir a vida concreta que se manifesta no ambiente onde o processo educativo está se desenvolvendo.

This paper aims to introduce, in the context of Latin America, the theoretical epistemic discussion regarding the theme of the ‘common’ as a political principle which substantiates instituting and autonomous processes of government, control and community regulation. The work seeks to relate a democratic scenario of the ‘common’ with the discourses of pluralist and decolonial normativity, in a way that would guarantee not only horizontal communal self-management, but also a legitimate ordering of forms of life, founded on common interest, social (...) relations and interconnected structures. For this purpose the instrument of critical-socio-legal analysis is applied at the intersections with the ‘participative-communitary’ type of legal pluralism. Our proposal is to combine the contemporary meaning of the ‘common’, its relation to the Latin American principles of ‘buen vivir’ (living well) and ‘interculturalidade’ (interculturality), as well as the instituting practice of the ‘common’, that engenders a normativity built ‘from below’, which is in opposition to the traditional positivist and state legal system imposed through colonization in Latin America. Such achievements that, although formalized, are not being successful against institutional ruptures, have ‘cloistered’ the practices of the ‘common’ and made the existence of legal pluralism invisible.

Ethical dilemmas raised by the use of nanotechnology in medical practice can be viewed from several perspectives: religious spiritualist perspective, the perspective of human dignity (nanotechnologies can be thought of as an affront to human dignity), the issue of controversial choice. The article aims to expose some bioethical dilemmas in using synthetic biology and nanotechnologies. Nowadays is often brought into discussion the fact it is possible to appear in the future new human species resulted not via natural selection and evolution, (...) but through the demiurgic effect of technology development in areas such as: synthetic biology, genetics, neurobiology and neurosciences, prosthesis technology and not least of artificial intelligence research. We will also refer into this paper at the possible raised challenges to ethicists who are oriented towards an ethics of species. Those challenges are raised right from the dawn of a consciousness of species, a social construction generated by changes of the meaning of belonging to humanity. During our article we argue that medical technology, especially genetics, medical assisted human reproduction and not least synthetic biology, require a rethinking ethical meanings of applying those technologies in everyday practices.

Perché quella faccia triste, lettore? Non sapere ti rende infelice. Non sai nulla di quello che ti circonda: non sai come fa a volare l'aereo che ti porterà a Londra, non sai quante zampe ha una Pseudoiulia cambriensis, come funziona il wi-fi, quanta acqua c'è nell'Oceano Atlantico. Sai cosa vuol dire entelechìa? Quanti capelli abbiamo in testa? Hai mai provato a contare tutte le stelle? No, ma l'ha già fatto l'astronomo Ipparco, e le notizie non sono buone: non potremo saperlo (...) mai. Più cerchi di trovare risposte più si formulano ulteriori domande. Ogni informazione è superata nel momento in cui la ricevi, ogni novità è storia vecchia. Grazie a Internet puoi sapere dove sono i tuoi amici in questo momento, con chi sono, cosa fanno. Ma ti interessa davvero? Se digiti parole a caso su Google (“kefYDl9”) qualche risultato verrà fuori di sicuro. Ma saperlo potrà farti vivere meglio? Hai uno sguardo sconsolato, lettore. Non sai che potresti vivere anche senza tutte queste conoscenze. Tu sei Prometeo, prigioniero del fuoco. Sei il fratello spirituale di Friedrich Nietzsche. Se fossi un personaggio di Game of Thrones saresti il Guardiano della Notte Jon Snow, il paladino che lotta trafitto dal dolore di non conoscere né il suo passato né il suo destino. Non lo conosci, ma forse non hai mai voluto saperlo. Anche sapere ti rende infelice: sai benissimo che più cose riuscirai a conoscere più diventerai ignorante. È il paradosso dell'ignoranza: non sapremo mai cosa esattamente sappiamo, e sappiamo solamente ciò che pensiamo di sapere. (shrink)

The essay examines Thomas Hill Green’s idealistic reading of Aristotle’s Metaphysics and De anima, starting from his “monopsychist” view of human understanding. His criticism of the Aristotelian notion of substance leads him to a recalibration of hylomorphism and a “noetization” of matter, which could be seen as an averroizing move. Green holds that there is only one “Eternal Consciousness” and that the individual thinking subjects are particular manifestations of it. As for Averroes’ unity of intellect, this idea derives from a (...) “left-wing” account of the potency of thought. But there are several other ontological, ethical, religious, and political consequences in making potency something essentially spiritual. The comparison between the two philosophers could help to throw light on the ‘obscure’ conception of “Eternal Consciousness”. (shrink)

A Doutrina Espírita, codificada na França no século XIX, tem entre seus principais postulados a crença em um Deus único, na imortalidade da alma, na pluralidade dos mundos habitados, na comunicabilidade entre espíritos e na reencarnação. De leves pancadas a mesas girantes, nos salões parisienses, o fenômeno, nos primeiros momentos, era recebido com incredulidade ou frivolidade por aqueles que participavam das reuniões. Até o estudo realizado pelo pedagogo Hippolyte-Léon Denizard Rivail, não se imaginava que tais eventos sofressem ação direta de (...) Espíritos. O professor Rivail, sob o pseudônimo de Allan Kardec, foi o principal organizador, sistematizador e codificador da Doutrina Espírita. Orientado pelos Espíritos, publicou vários livros sobre o Espiritismo, entre eles O Livro dos Espíritos, que é alvo deste estudo. A codificação espírita surge em um período histórico em que o pensamento filosófico e científico encontravam-se profundamente influenciados por ideais do racionalismo e do positivismo, bem como pelo modelo evolucionista. A palavra evolução, tomada do fascínio que exercia no século XIX, devido à ideia de modernidade, é central para o espiritismo. O objetivo desta investigação está em pesquisar o sentido de evolução apresentado nas obras codificadas por Allan Kardec, em especial, no Livro dos Espíritos, e como esta compreensão pode contribuir para o diálogo inter-religioso. Parte da hipótese que, para a Doutrina Espírita, a evolução é central na vida do ser humano na medida em que possibilita modificações do comportamento humano. Evoluir implica num convite para sair de si para buscar o próximo. O pluralismo religioso desafia as pessoas e as religiões a viver a responsabilidade de entender o outro e suas crenças como um atributo de liberdade e de escolha. Neste horizonte de evolução, o diálogo inter-religioso torna-se princípio essencial para o avanço espiritual. Representa um incremento à nossa habilidade de escutar e compartilhar. O método de abordagem deste estudo foi o hipotético-dedutivo e da pesquisa bibliográfica, por meio da consulta de livros e textos psicografados. Por meio da codificação espírita, em especial, no Livro dos Espíritos, buscar-se-á, no sentido de evolução, um fator que pode favorecer um entendimento das alteridades e de cosmovisões religiosas, abrindo caminhos para variados diálogos. Por fim, pode afirmar que a codificação, por seu conteúdo universalista, pelo processo de regeneração moral do ser humano e de abertura às religiões, pode contribuir, com grandes ganhos, para construções de diálogos inter-religiosos.

This paper will show that attempts to control the body in late capitalism are replete with symbolic violence. Filipinos have not succeeded in confining the body, thereby validating Foucault's (1980) critique of the repressive hypothesis. Ordinary narratives about the body in the Philippines exist not in the context of a settled template of silenced debates and repressed desires, but in the explosion of discourse and contestations, and of an intricate articulation between popular knowledge and truth on one hand, and the (...) ordinary and everyday experience of pleasure and desire on the other.

The present brief commentary to Englert’s recent article on Kant’s distinction between practical ideas and ideals extends the significance of its contribution by considering the psychological dimensions underpinned by those ethical concepts. According to regulatory focus theory, in the moral domain the prevention focus subsumes duties and obligations, whereas the promotion focus underlies aspirations toward virtue. I argue here that prevention motives induce the enactment of behaviours consistent with ethical rules corresponding to Kant’s practical idea, and that promotion motives inspire (...) imitation processes aimed at advancement toward the archetypal excellence of Kant’s practical ideal. I conclude discussing the relevance and value, beyond Kant’s ethical conception, of a psychological analysis of the main Western normative theories through the lens of regulatory focus and the other motivational primitives.

Beyond the terms used by the various pre-Socratic thinkers (thymós, kardia, eros, etc.) and beyond also the different settings adopted in their discussion,it is possible to find the reference to a reality which is susceptiblebut to be described in the three essential characteristics of desire:1) The change of a previous situation, which is almost always understood as an exit from one reality to another.2) The push, placed at the origin of this exit, which appears as opposition or attraction about another (...) reality. 3) Finally the achievement of a new situation, equal or very similar to the previous situation.
