Visitare il “pianeta d’argento”, conquistare il silenzioso globo che rischiara ogni notte, è stato il sogno dell’uomo di età moderna. Tra Cinque e Settecento, infatti, dall’epoca delle grandi scoperte geografiche al secolo dei Lumi, scrittori, scienziati, uomini di fede e di cultura hanno tentato in ogni modo di concretizzare questa inafferrabile visione. Grazie a un lungo e minuzioso lavoro di ricerca, Marco Ghione racconta la loro storia e illustra le soluzioni tecniche che tanti, eccezionali cittadini della Repubblica delle Lettere hanno (...) elaborato per trasformare l’impossibile in realtà, dalle macchine volanti di Cyrano de Bergerac e Francis Godwin alle creature soprannaturali fantasticate da Keplero e Kircher. Intanto, scienziati e astronomi andavano puntualmente definendo le prime riproduzioni attendibili della superficie lunare, con una nomenclatura sistematica che, a partire dall’Almagestum novum di Giovanni Battista Riccioli, è giunta fino ai giorni nostri, all’impresa dell’Apollo 11 e allo sbarco sulla luna. Completa il volume la prima traduzione italiana di due testi fondamentali della letteratura in materia: l’Iter Lunare, di David Russen (1703), e A Trip to the Moon, di Murtagh McDermot (1727).

We examine two very different approaches to formalising real computation, commonly referred to as “Computable Analysis” and “the BSS approach”. The main models of computation underlying these approaches—bit computation and BSS, respectively—have also been put forward as appropriate foundations for scientific computing. The two frameworks offer useful computability and complexity results about problems whose underlying domain is an uncountable space. Since typically the problems dealt with in physical sciences, applied mathematics, economics, and engineering are also defined in uncountable domains, it (...) is fitting that we choose between these two approaches a foundational framework for scientific computing. However, the models are incompatible as to their results. What is more, the BSS model is highly idealised and unrealistic; yet, it is the de facto implicit model in various areas of computational mathematics, with virtually no problems for the everyday practice. This paper serves three purposes. First, we attempt to delineate what the goal of developing foundations for scientific computing exactly is. We distinguish between two very different interpretations of that goal, and on the separate basis of each one, we put forward answers about the appropriateness of each framework. Second, we provide an account of the fruitfulness and wide use of BSS, despite its unrealistic assumptions. Third, according to one of our proposed interpretations of the scope of foundations, the target domain of both models is a certain mathematical structure. In a clear sense, then, we are using idealised models to study a purely mathematical structure. The third purpose is to point out and explain this intriguing phenomenon and attempt to make connections with the typical case of idealised models of empirical domains. (shrink)

El año 2001 representó un momento de quiebre en la historia reciente argentina. Las repercusiones de la crisis económica, social y de representatividad política se hicieron presentes en todo el espectro cultural. El presente artículo parte de una hipótesis central: la omnipresencia del sonido durante la crisis explica el giro hacia lo sonoro en la producción musical posterior. Nuestro estudio se estructurará en tres partes: en una primera sección, examinaremos los sonidos de la crisis y su historicidad. En las otras (...) dos secciones, analizaremos las obras de compositores y colectivos artísticos durante la crisis y la poscrisis – BAS (Buenos Aires Sonora), Nicolás Varchausky, Juan Pampín y Carmen Baliero, entre otros ejemplos. Este análisis nos permitirá evaluar cómo los sonidos de la crisis y esta particular experiencia de la escucha permearon dentro del campo sonoro y musical. (shrink)

Les réformes économiques néolibérales, suite à la crise financière de 1991, ont provoqué des mutations dans l’économie indienne, son développement industriel et agricole. Celles-ci ont touché l’ensemble de la population mais particulièrement, les groupes sociaux classés comme les plus vulnérables, telles que les communautés autochtones adivasi. Du point de vue des politiques publiques, ce qui caractérise les Adivasis, c’est leur désavantage économique et social. Ils font donc partie d’une catégorie sociale ciblée par différents programmes nationaux de développement et de réduction (...) de la pauvreté, notamment par l’intermédiaire du Dongria Kondh Development Agency (DKDA pour son acronyme anglais), département gouvernemental de médiation entre le gouvernement central indien et le groupe autochtone Dongria Kondh. C’est sur ce groupe que porte notre enquête anthropologique. Le présent article, dont les résultats s’appuient sur neuf mois de travail sur le terrain entre 2011 et 2015, vise à mettre en évidence la manière dont les politiques publiques nationales visant les communautés de dongria ont des impacts environnementaux et sociaux significatifs.

La Bioética es una joven disciplina con apenas tres décadas de recorrido en nuestro país. Durante todo este tiempo, la Cátedra de Bioética de la Universidad Pontificia Comillas ha contribuido activamente a la reflexión, diálogo y divulgación de la Bioética. Este año, ha querido celebrar su XXV Seminario Interdiciplinar reuniendo a las principales instituciones y autores que han sido y son referentes ineludibles en esta reflexión bioética. Este libro recoge la mirada histórica del mucho y buen trabajo realizado en todo (...) este tiempo, la situación actual de esta disciplina que intenta servir a una sociedad en continuo cambio y las perspectivas de futuro que se plantean las principales instituciones que hoy por hoy dan forma a la Bioética española.

La experiencia de musulmanes, judíos y cristianos ante el sufrimiento, la muerte y la enfermedad tiene muchos puntos en común que es necesario y urgente resaltar. El libro está dividido entres partes que corresponden a las tres tradiciones analizadas. Consta de treinta artículos escritos por veintisiete autores. Participan profesores no sólo de las Universidades de Comillas, Deusto y Granada sino del Instituto Bíblico de Roma, de la Universidad Gregoriana de Roma, de la Universidad de Munich, de la Universidad Complutense de (...) Madrid, del Seminario Evangélico Unido de Teología (SEUT) y de la Facultad de Teología de Catalunya. Colaboran, por supuesto, sacerdotes católicos, pastores protestantes, un rabino y el secretario del Consejo Europeo de Mezquitas. Sin duda, nos encontramos ante una gran aportación en el campo de la Bioética y en la reflexión en torno al dolor, la enfermedad y la muerte. (shrink)

Nelle Summulae del salmantino Domingo de Soto, la teoria della proposizione sembra rivelare un’irrisolta tensione tra l’opzione per la prospettiva terministica, la quale considera il significato della proposizione come il risultato dell’analisi semantica dei suoi componenti, e l’opzione per la prospettiva ‘dictistica’, che si concentra sul riferimento e sul senso globale della proposizione. La struttura della proposizione mentale, pur determinata in maniera ‘causale’ dalle sue componenti, il nome e il verbo, viene d’altronde a costituirsi in maniera ‘uni-qualitativa’, ossia per mezzo (...) di un unico atto mentale, con il quale si designa uno stato di cose esterno . Il ‘valore di verità’ della proposizione, espresso sintatticamente mediante l’unione o la separazione di un termine da un altro, viene a denotare la conformità a un modo d’essere delle cose nella realtà.

Cornelio Lanci si avvale di sei trattati degli _Esempi della virtù delle donne_ per testimoniare l’_humanitas_ _ante litteram_ di Zenobia, sovrana dell’impero d’Oriente ai tempi di Aureliano. L’articolo si propone di indagare le possibili fonti cui l’urbinate attinse per approntare le sue personali riscritture delle gloriose imprese della regina di Palmira.

In juxtaposition with the myth and tragedy of Ovid’s Medea, this paper investigates the possibility within the Kantian conception of agency of understanding moral evil as acting against one’s better judgment. It defends the thesis that in Kant self-deception, i. e. the intentional untruthfulness to oneself, provides the fundamental structure for choosing against the moral law. I argue that, as Kant’s thought progresses, self-deception slowly proceeds to become the paradigmatic case of moral evil. This is discussed with regard to two (...) important topics in his later moral philosophy: the doctrine of radical evil and the crucial role of the duty of truthfulness in ethics. The inquiry into Kant’s theory of conscience unfolds both against this theoretical background and in light of its historical roots in the polemic against casuistry and probabilism. This contribution closes with a brief look at the tools Kant implements to counter this tendency to self-deception in moral judgment and particularly at the role casuistry plays within his conception of moral education.

A novel theoretical framework for an embodied, non-representational approach to language that extends and deepens enactive theory, bridging the gap between sensorimotor skills and language. -/- Linguistic Bodies offers a fully embodied and fully social treatment of human language without positing mental representations. The authors present the first coherent, overarching theory that connects dynamical explanations of action and perception with language. Arguing from the assumption of a deep continuity between life and mind, they show that this continuity extends to language. (...) Expanding and deepening enactive theory, they offer a constitutive account of language and the co-emergent phenomena of personhood, reflexivity, social normativity, and ideality. Language, they argue, is not something we add to a range of existing cognitive capacities but a new way of being embodied. Each of us is a linguistic body in a community of other linguistic bodies. The book describes three distinct yet entangled kinds of human embodiment, organic, sensorimotor, and intersubjective; it traces the emergence of linguistic sensitivities and introduces the novel concept of linguistic bodies; and it explores the implications of living as linguistic bodies in perpetual becoming, applying the concept of linguistic bodies to questions of language acquisition, parenting, autism, grammar, symbol, narrative, and gesture, and to such ethical concerns as microaggression, institutional speech, and pedagogy.
