According to the form of logical pluralism elaborated by Beall and Restall there is more than one relation of logical consequence. Since they take the relation of logical consequence to reside at the very heart of a logical system, different relations of logical consequence yield different logics. In this paper, we are especially interested in understanding what are the consequences of endorsing Beall and Restall’s version of logical pluralism vis-à-vis the normative guidance that logic is taken to provide to reasoners. (...) In particular, the aim of this paper is threefold. First, in Sections 2 and 3, we offer an exegesis of Beall and Restall’s logical pluralism as a thesis of semantic indeterminacy of our concept of logical consequence – i.e. understood as indeterminacy logical pluralism. Second, in Sections 4 and 5, we elaborate and critically scrutinize three models of semantic indeterminacy that we think are fit to capture Beall and Restall’s indeterminacy logical pluralism. Third, in Section 6, following Beall and Restall’s assumption that the notion of logical consequence has normative significance for deductive reasoning, we raise a series of normative problems for indeterminacy logical pluralism. The overall conclusion that we aim to establish is that Beall and Restall’s indeterminate logical pluralism cannot offer an adequate account of the normative guidance that logic is taken to provide us with in ordinary contexts of reasoning.

Plato's Republic has proven to be of astounding influence and importance. Justly celebrated as Plato's central text, it brings together all of his prior works, unifying them into a comprehensive vision that is at once theological, philosophical, political and moral. The essays in this volume provide a picture of the most interesting aspects of the Republic, and address questions that continue to puzzle and provoke, such as: Does Plato succeed in his argument that the life of justice is the most (...) attractive one? Is his tripartite analysis of the soul coherent and plausible? Why does Plato seem to have to force his philosopher-guardians to rule when they know this is something that they ought to do? What is the point of the strange and complicated closing Myth of Er? This volume will be essential to those looking for thoughtful and detailed excursions into the problems posed by Plato's text and ideas. (shrink)

In the paper it is argued that bridging the digital divide may cause a new ethical and social dilemma. Using Hardin's Tragedy of the Commons, we show that an improper opening and enlargement of the digital environment (Infosphere) is likely to produce a Tragedy of the Digital Commons (TDC). In the course of the analysis, we explain why Adar and Huberman's previous use of Hardin's Tragedy to interpret certain recent phenomena in the Infosphere (especially peer-to-peer communication) may not be entirely (...) satisfactory. We then seek to provide an improved version of the TDC that avoids the possible shortcomings of their model. Next, we analyse some problems encountered by the application of classical ethics in the resolution of the TDC. In the conclusion, we outline the kind of work that will be required to develop an ethical approach that may bridge the digital divide but avoid the TDC. (shrink)

In this paper we introduce three methods to approach philosophical problems informationally: Minimalism, the Method of Abstraction and Constructionism. Minimalism considers the specifications of the starting problems and systems that are tractable for a philosophical analysis. The Method of Abstraction describes the process of making explicit the level of abstraction at which a system is observed and investigated. Constructionism provides a series of principles that the investigation of the problem must fulfil once it has been fully characterised by the previous (...) two methods. For each method, we also provide an application: the problem of visual perception, functionalism, and the Turing Test, respectively. (shrink)

It has been observed that whereas painters and musicians are likely to be embarrassed by references to the beauty in their work, mathematicians instead like to engage in discussions of the beauty of mathematics. Professional artists are more likely to stress the technical rather than the aesthetic aspects of their work. Mathematicians, instead, are fond of passing judgment on the beauty of their favored pieces of mathematics. Even a cursory observation shows that the characteristics of mathematical beauty are at variance (...) with those of artistic beauty. For example, courses in art appreciation are fairly common; it is however unthinkable to find any mathematical beauty appreciation courses taught anywhere. The purpose of the present paper is to try to uncover the sense of the term beauty as it is currently used by mathematicians. (shrink)

In the Aeneid, Virgil sets out to achieve a new sublime style, paradoxically steeped in the common parlance. He aims for the spontaneity of everyday language to win readers’ involvement, while elaborating a discourse both expressively taut and stylistically marked, that avoids a register too colloquial or prosaic. Above all, he tirelessly deploys an array of subtle strategies – below the threshold of perception – that defamiliarize language in order to elevate its style. The present paper furnishes a selection of (...) case studies. (shrink)

An application of Narrative Knowledge Representation Language (NKRL) techniques on (declassified) ‘terrorism in Southern Philippines’ documents has been carried out in the context of the IST Parmenides project. This paper describes some aspects of this work: it is our belief, in fact, that the Knowledge Representation techniques and the Intelligent Information Retrieval tools used in this experiment can be of some interest also in an ‘Ontological Modelling of Legal Events and Legal Reasoning’ context.

Esse estudo apresenta os conceitos de documento e documentação propostos por Paul Otlet (1868-1944) presentes no âmbito da Revista do Serviço Público (RSP). Publicada desde 1937, a RSP contempla artigos nas áreas de Administração e Gestão pública, Políticas públicas e Economia do setor público, sendo considerada um importante veículo de informação no Brasil, contemporâneo ao período de efervescência do pensamento de Otlet. A pesquisa consiste numa Revisão Sistemática de Literatura (RSL) com análise documental da RSP no período entre 1951 e (...) 1975. Como procedimento de seleção dos artigos, utiliza o protocolo de pesquisa RSL elaborado por Valentim (2020). A partir do corpus de análise dos textos recuperados identifica os artigos que apresentam os conceitos de “documento” e “documentação” segundo Otlet, bem como os elementos constitutivos sobre o cenário da documentação no Brasil, na perspectiva da publicação de autores brasileiros na RSP, concluindo que os trabalhos analisados contemplam e ampliam a temática da Documentação com importantes reflexões de Otlet para a Ciência da Informação no Brasil.

El autor trabaja en este artículo una de las obras más citadas y controvertidas del Hegel de su periodo maduro cual es los Principios de la Filosofía del Derecho o Derecho Natural y Ciencia Política, comúnmente conocida como Filosofía del Derecho y desarrolla algunos temas que permanecen como cuestiones abiertas al debate o como aspectos objetables, tanto en su teoría del espíritu objetivo como en su interpretación.

In this paper we show that the Gupta-Belnap systems S# and S* are П12. Since Kremer has independently established that they are П12-hard, this completely settles the problem of their complexity. The above-mentioned upper bound is established through a reduction to countable revision sequences that is inspired by, and makes use of a construction of McGee.

Interest in the intersection between bilingualism and cognitive control and accessibility to neuroimaging methods have resulted in numerous studies with a variety of interpretations of the bilingual cognitive advantage. Neurocomputational Emergentism (or Neuroemergentism for short) is a new framework for understanding this relationship between bilingualism and cognitive control. This framework considers Emergence, in which two small elements are recombined in an interactive manner, yielding a non-linear effect. Added to this is the notion that Emergence can be captured in neural systems (...) using computationally inspired models. This review poses that bilingualism and cognitive control, as examined through the Neuroemergentist framework, are interwoven through development and involve the non-linear growth of cognitive processing encompassing brain areas that combine and recombine, in symbiotic and parasitic ways, in order to handle more complex types of processing. The models that have sought to explain the neural substrates of bilingual cognitive differences will be discussed with a reinterpretation of the entire bilingual cognitive advantage within a Neuroemergentist framework incorporating its neural bases. It will conclude by discussing how this new Neuroemergentist approach alters our view of the effects of language experience on cognitive control. Avenues to move beyond the simple notion of a bilingual advantage or lack thereof will be proposed. (shrink)

El autor sigue a Ana Arendt para examinar el tema de la responsabilidad personal bajo dictadura. Ante el argumento de que no había opciones pues se era una ‘ruedecilla del engranaje’, afirma que el mal menor no deja de ser un mal, y que la verdadera pregunta moral no es ‘por qué obedeciste’ sino ‘por qué ayudaste’.

The contribution describes some aspects related to the representation of special curves; recalling mechanisms created specifically for the design of these curves, which have particular characteristics. Through the construction of a simple apparatus, consisting of two pendulums—which oscillate at the same time- it is possible to graphically reproduce Lissajous’ experiments on the commuting vibrations of the diapasons. This equipment was first built by Samuel Charles Tisley (London 1829-Unknown), under the name of harmonographer. The contribution aslo illustrates the essential characteristics of (...) the harmonograph—born as a means of analysing vibrations—but which, by its principle belongs to mechanics, for its applications to acoustic science and geometry for the ability to draw “harmonious” curves.

This essay has two goals. The first is to define the behavioristic study of natural events and to classify behavior. The second is to stress the importance of the concept of purpose.Given any object, relatively abstracted from its surroundings for study, the behavioristic approach consists in the examination of the output of the object and of the relations of this output to the input. By output is meant any change produced in the surroundings by the object. By input, conversely, is (...) meant any event external to the object that modifies this object in any manner. (shrink)

Este artículo estudia la revisión que hace Antonio Pérez de la identidad intencional de Pedro Auréolo entre el ser aparente de una cosa como conocida y su ser real extramental. La teoría de la cognición de Pérez es claramente deudora de la teoría de la intencionalidad de Auréolo. Al igual que este, Pérez se apoya en el instrumento lógico de la connotación y en la identidad entre la especie inteligible y el acto de conocimiento. Pérez está de acuerdo con la (...) teoría de Auréolo, afirmando una identidad de indistinción entre el ser aparente de la cosa como conocida y el ser real de la cosa extramental. Sin embargo, Pérez parece no estar plenamente satisfecho con la teoría de la cognición de Auréolo, e introduce algunos cambios relevantes. En primer lugar, emplea la doctrina suareziana de que todo acto intencional, aunque apunta directamente a un objeto, reflexiona virtual o indirectamente sobre sí mismo. Como consecuencia, apoya una identidad entre el lado formal –es decir, el acto de cognición– y el lado objetivo –es decir, la cosa reconocida–. En segundo lugar, ofrece una definición de la identidad de indistinción que difiere de la de Auréolo. Al hacerlo, Pérez equipara el ser aparente con una forma universal, es decir, el acto de cognición como tal, caracterizando todo acto particular de cognición como propio de todo ser inteligente. Esta forma indeterminada, entonces, puede ser determinada por todo objeto posible. (shrink)

Este artículo pretende estudiar la crítica de Antonio Pérez a la teoría de la identidad intencional de Pedro Auréolo. La teoría de la cognición de Pérez es claramente deudora de la doctrina de la intencionalidad de Auréolo. El jesuita español utiliza a menudo las mismas expresiones lingüísticas que Auréolo (como "ser aparente") y coincide con él en la identidad intencional entre el conocedor -que coincide en acto con el acto de conocer- y el objeto conocido, que es lo mismo que (...) existe fuera del intelecto. Tanto Pérez como Auréolo basan su teoría de la identidad intencional en el De anima de Aristóteles, pero el jesuita español señala una incoherencia en la doctrina de Auréolo, que contradice la concisa afirmación de Aristóteles sobre la identidad entre el conocedor y lo conocido durante el acto de conocimiento. Al examinar a fondo la teoría de la identidad intencional de Auréolo, concebida como una especie de identidad de indistinción, Pérez señala una incoherencia entre la descripción que hace Auréolo del acto de cognición y su concepción de la identidad de indistinción. Además, Pérez parece considerar insuficiente la identidad de indistinción de Auréolo utilizada para describir la identidad intencional que caracteriza el acto de cognición. En consecuencia, ofrece una nueva definición de identidad indistinta para presentar el ser aparente como una realidad indeterminada que puede ser determinada por cualquier contenido inteligible. Esta revisión péreziana de la teoría del ser aparente de Auréolo, por un lado, puede verse como un caso de revisionismo escolástico temprano moderno aplicado a un pensador medieval y, por otro, encuentra una aplicación más amplia en la metafísica y la antropología filosófica de Pérez.
