The dissertation has two parts, each dealing with a problem, namely: 1) What is the most adequate account of fuzziness -the so-called phenomenon of vagueness?, and 2) what is the most plausible solution to the sorites, or heap paradox? I will try to show that fuzzy properties are those which are gradual, amenable to be possessed in a greater or smaller extent. Acknowledgement of degrees in the instantiation of a property allows for a gradual transition from one opposite to the (...) other, each intermediate stage constituting an overlap in certain proportion of both contraries. Hence, degrees in the possession of a property give rise to simple contradictions. The reason why I have chosen those two questions is that they provide the main philosophical motivation for a particular brand of an infinite valued and paraconsistent logic. I will claim that Classical logic (CL) is not adequate to handle fuzzy situations, and, being deficient, is in need of being expanded to make room for degrees of truth and weak contradictions. One can hardly deny the importance of the debate, since what is ultimately at stake is what the limits of truth, rationality, intelligibility and possibility are. The main disciplines within which the research moves are the philosophy of language, philosophy of logic, and ontology. (shrink)

Resumen Este artículo examina siete concepciones filosóficas acerca de la libertad -incluyendo la distinción entre libertad negativa y positiva, liberal y republicana-, ejemplificándolas con representantes de la historia de la filosofía. Por otra parte, para enriquecer la mirada desde un texto jurídico concreto, examinamos la Constitución ecuatoriana de 2008. El propósito principal que ha animado esta investigación es el de sondear las distintas visiones que se han propuesto sobre la libertad, en su triple relación con: 1) los valores, tales como (...) el bien común y la igualdad; 2) el tipo de deber correspondiente que tienen que cumplir los particulares y la sociedad con respecto al sujeto portador del derecho a la libertad; y 3) el Estado y las leyes. Aspiramos a que los resultados alcanzados aporten mayor claridad en aquellos debates de la filosofía normativa en los que está involucrada la libertad.The paper examines seven philosophical conceptions of freedom -including the distinctions between positive and negative liberty, and liberal and republican liberty-, exemplifying them with great authors in the history of philosophy. On the other hand, in order to enrich the vision with a concrete legal document, we examine the Ecuadorian Constitution of 2008. The central aim of the research is to probe the use made by those who participated in the drafting of that Constitution of philosophical ideas concerning liberty in its threefold relation to: 1) values, such as common good and equality; 2) the correlative duties imposed on individuals and the society at large with respect to the holder of the right to freedom; and 3) the state and its laws. We hope that the results provide greater clarity in those debates of normative philosophy in which freedom is involved. (shrink)

Reseña de Lorenzo Peña, Hallazgos filosóficos, Universidad Pontificia de Salamanca, Salamanca, 1992, 363 pp.

Para Eugenio d’Ors, la vida humana no se define por su relación con la muerte, sino como principio creador de formas que se afirma a sí mismo. En cambio, la muerte sí se define como lo radicalmente opuesto a la vida, un principio de negación y destrucción, de fatalidad y resistencia. De este modo se establece entre ambos principios una relación dialéctica, una tensión de antagonistas que hace que la vida sea una permanente lucha contra la muerte. Por ello el (...) planteamiento de d’Ors acerca de la muerte adquiere un fuerte sentido ético y beligerante, afirmando la necesidad de vivir en actitud alerta y combativa. (shrink)

This paper investigates modular combinations of temporal logic systems. Four combination methods are described and studied with respect to the transfer of logical properties from the component one-dimensional temporal logics to the resulting combined two-dimensional temporal logic. Three basic logical properties are analyzed, namely soundness, completeness, and decidability. Each combination method comprises three submethods that combine the languages, the inference systems, and the semantics of two one-dimensional temporal logic systems, generating families of two-dimensional temporal languages with varying expressivity and varying (...) degrees of transfer of logical properties. The temporalization method and the independent combination method are shown to transfer all three basic logical properties. The method of full join of logic systems generates a considerably more expressive language but fails to transfer completeness and decidability in several cases. So a weaker method of restricted join is proposed and shown to transfer all three basic logical properties. (shrink)

Nesta entrevista, conduzida por Gonçalo Marcelo e Maria Luísa Portocarrero, Daniel Frey, professor de filosofia da religião na Universidade de Estrasburgo e Presidente do Conselho Científico do Fonds Ricoeur, apresenta alguns aspetos centrais da sua investigação filosófica, do seu desenvolvimento intelectual e das atividades desenvolvidas no Fonds Ricoeur. Daniel Frey expõe a sua teoria hermenêutica da leitura, influenciada por Gadamer e Ricoeur, mostrando a especificidade da abordagem hermenêutica da leitura. Na entrevista, o autor também explora a importância da filosofia (...) do jovem Ricoeur dos anos 1950‑1960, e a evolução da relação entre filosofia e religião em Ricoeur. Fazendo uma breve descrição do estatuto das obras que se tornam “clássicas” e dos projetos recentes do Fonds Ricoeur, como a digitalização dos arquivos de Ricoeur, esta entrevista de Daniel Frey mostra‑nos até que ponto o trabalho de Ricoeur se encontra hoje aberto a novas leituras e interpretações.

Robert Brandom propõe um modelo de interação social no qual defende que as atitudes práticas dos usuários da linguagem instituem os conteúdos semânticos e as normas inferenciais que determinam seus usos. Assim, o que ele descreve é uma prática linguística, caracterizado por asserções, que mostra como as atitudes dos agentes, diante das asserções sendo produzidas e consumidas, devem ser entendidas para que instituam conteúdos inferencialmente articulados. Ademais, Brandom relaciona a prática assertiva e o entendimento inferencial do conteúdo semântico a um (...) paradigma racionalista, sugerindo que os conteúdos que aparecem em asserções são aquilo que podem ser oferecidos ou exigidos, dentro da prática de uso da linguagem, como razões. Considerando estas ideias, o objetivo deste trabalho é desenvolver e relacionar os conceitos de "asserção", "inferência" e "razão", tais como Brandom os compreende. (shrink)

This article deals with the relationship between the creator of psychoanalysis, Sigmund Freud, and the Latvian-born Chilean professor of physiology – and endocrinologist and anthropologist – Alejandro (or Alexander) Lipschütz. Up till now, the historiography of psychoanalysis in Chile has ignored the existence of this relationship, that is to say, the fact that there exists an interesting exchange of correspondence as well as references to Lipschütz in some important works published by Freud and in Freud’s correspondence with the Hungarian psychoanalyst (...) Sándor Ferenczi. There are also references to works on psychoanalysis carried out by Lipschütz in Chile. The Freud–Lipschütz relationship allows us to examine two interesting topics in contemporary historiographical approaches to psychoanalysis. First, it permits us to reflect on the connections that Freud and Ferenczi sought to establish between psychoanalysis and biology (endocrinology in particular) as a strategy to address criticism of the scientific foundations of psychoanalysis and, therefore, to help legitimize psychoanalysis in the field of science. Second, the relationship between Freud, working in a culturally influential city such as Vienna, and Lipschütz, working in a ‘peripheral’ country such as Chile, paves the way to reflect on the consequences of a history of psychoanalysis written from the perspective of the ‘margins’. This is a history that focuses not on regions where early industrialization and modernization processes, along with an important academic and scientific tradition, help explain the interest in and reception of psychoanalysis, but on regions where different sets of conditions have to be examined to explain appropriation and dissemination processes.

A topos version of Cantor’s back and forth theorem is established and used to prove that the ordered structure of the rational numbers (Q, <) is homogeneous in any topos with natural numbers object. The notion of effective homogeneity is introduced, and it is shown that (Q, <) is a minimal effectively homogeneous structure, that is, it can be embedded in every other effectively homogeneous ordered structure.

This book symposium comprises a précis of Nuno Venturinha’s Description of Situations: An Essay in Contextualist Epistemology together with four critical commentaries on different aspects of the book by Marcelo Carvalho, João Vergílio Gallerani Cuter, Marcos Silva and Darlei Dall’Agnol, and the author’s replies.

O ceticismo acadêmico se encontra utilizado na formulação dos preceitos epistêmicos para a reformulação da ciência, nas _Règles Pour La Direction De L’Esprit _ ( 1701, Amsterdam, texto póstumo e inacabado). O probabilismo de Carnéades, compreendido como o principal vetor do ceticismo acadêmico na modernidade, fundamenta a certeza. Outras teses para a correção epistêmica do espírito parecem advir da tradição acadêmica, como a de fi nição de _science _ como _sagesse_, por exemplo ( _Règle _ _I_ ). Desse modo, a (...) busca da verdade (coordenada principal das _Règles_, como nos evidencia a _Règle _ _IV_ ) não abdica do ceticismo. Tratar-se-á, neste artigo, de compreender que o probabilismo acadêmico aparece no projeto de busca da verdade das _Règles _ de modo negativo _, _ pois Descartes ataca a modalidade do provável. Outros tópicos acadêmicos aparecem em questão, como a busca de sabedoria, a mitigação da dúvida, a disciplina do assentimento pela recusa do provável e a verdade do fi deísmo _. _ Estes tópicos se resumem ao método acadêmico, de fi nido pela recursividade epistêmica.

Amid the COVID-19 pandemic, a parallel crisis emerged in the form of an “infodemic,” where misinformation proliferated through social media at an unprecedented scale. This article delves into the evolving landscape of reliable and misinformation sources reporting on the pandemic, examining their communication dynamics. Leveraging a comprehensive data set encompassing 437,832 news published online by media organizations from January 2020 to December 2021, I employ structural change analysis and network-based natural language processing to explore these dynamics. The findings illuminate the (...) contrasting approaches adopted by reliable sources, which prioritize scientific discourse, and misinformation, which exhibits high topic volatility—rapid change in the focus—suggesting that misinformation sources frequently shift their attention to different topics. Notably, this highlights a deliberate strategy employed by misinformation purveyors, that is, creating false crises without authoritative resolutions, thereby fostering a sense of lack of control, chaos, and uncertainty. Furthermore, the sentiment and morality analysis of COVID-19 news reveal that reliable news tends to maintain a balanced and neutral tone, while misinformation often exhibits a highly negative and morally charged narrative. These results carry significant implications for devising effective social countermeasures against misinformation at various stages of the pandemic. (shrink)

El documento de Medellín constituye el punto de partida de una reflexión cristológica original en América Latina. En este ensayo se concluye que esta originalidad estriba en haber reconocido a la historia una importancia epistemológica mayor. Esta innovación condujo a los teólogos latinoamericanos a repensar la cruz en favor de la liberación de los pobres más que como instrumento de perdón de los pecados. A este efecto se compara la cristología de la liberación desarrollada después de la II Conferencia General (...) del Episcopado Latinoamericano con la cristología de los manuales preconciliares de De Verbo incarnato. La crítica de Eduardo Briancesco a la cristología de Medellín, recogida al comienzo del texto, es útil para ver la transición de un paradigma teológico a otro. (shrink)

La edición genética tiene muchas aplicaciones en casi todos los ámbitos de la sociedad, pero también puede tener consecuencias impredecibles. La edición del genoma de la línea germinal humana es el centro de una discusión mundial. Debido al creciente número de cuestionamientos científicos, éticos y políticos, muchos sin una respuesta concreta, el consenso de la comunidad científica manifiesta que sería inapropiado modificar genéticamente embriones humanos. Se considera necesario un debate serio y abierto para decidir si se debe suspender o fomentar (...) la investigación en este sentido. En el presente documento, se exponen algunos argumentos audaces a favor de la eliminación de los genes nocivos del genoma humano y los riesgos que supone el eugenismo liberal. (shrink)

The main aim of this paper is to introduce the logics of evidence and truth $$LET_{K}^+$$ and $$LET_{F}^+$$ together with sound, complete, and decidable six-valued deterministic semantics for them. These logics extend the logics $$LET_{K}$$ and $$LET_{F}^-$$ with rules of propagation of classicality, which are inferences that express how the classicality operator $${\circ }$$ is transmitted from less complex to more complex sentences, and vice-versa. The six-valued semantics here proposed extends the 4 values of Belnap-Dunn logic with 2 more values (...) that intend to represent (positive and negative) reliable information. A six-valued non-deterministic semantics for $$LET_{K}$$ is obtained by means of Nmatrices based on swap structures, and the six-valued semantics for $$LET_{K}^+$$ is then obtained by imposing restrictions on the semantics of $$LET_{K}$$. These restrictions correspond exactly to the rules of propagation of classicality that extend $$LET_{K}$$. The logic $$LET_{F}^+$$ is obtained as the implication-free fragment of $$LET_{K}^+$$. We also show that the 6 values of $$LET_{K}^+$$ and $$LET_{F}^+$$ define a lattice structure that extends the lattice L4 defined by the Belnap-Dunn four-valued logic with the 2 additional values mentioned above, intuitively interpreted as positive and negative reliable information. Finally, we also show that $$LET_{K}^+$$ is Blok-Pigozzi algebraizable and that its implication-free fragment $$LET_{F}^+$$ coincides with the degree-preserving logic of the involutive Stone algebras.

We introduce a methodology whereby an arbitrary logic system L can be enriched with temporal features to create a new system T(L). The new system is constructed by combining L with a pure propositional temporal logic T (such as linear temporal logic with Since and Until) in a special way. We refer to this method as adding a temporal dimension to L or just temporalising L. We show that the logic system T(L) preserves several properties of the original temporal logic (...) like soundness, completeness, decidability, conservativeness and separation over linear flows of time. We then focus on the temporalisation of first-order logic, and a comparison is make with other first-order approaches to the handling of time. (shrink)

Se constató que aun con acceso tecnológico (...) limitado, se desarrollaron diversos usos de las TIC para el desarrollo de los procesos de enseñanza y de aprendizaje. (shrink)

No cinema brasileiro recente, o diálogo entre o documentário e a ficção tem merecido destaque, com produções de baixo orçamento e ideias originais. É o caso de Santiago (João Moreira Salles, 2007) e Viajo Porque Preciso, Volto Porque Te Amo (Marcelo Gomes, Karim Aïnouz, 2009), filmes que trabalham esse diálogo de forma sutil e diegética, ressignificando imagens de um arquivo próprio, pessoal.

Para hacer frente a los riesgos de rezago y deserción escolar durante Covid-19, las universidades implementaron programas de apoyo y de atención tutorial virtuales. Los esquemas de acompañamiento profesor-estudiante se han documentado mayoritariamente, pero poco se ha dicho sobre otras modalidades como el acompañamiento entre pares. Bajo este panorama se planteó un diseño exploratorio para identificar los tipos de ayuda educativa desplegados durante la pandemia en el marco de un programa de tutorías entre iguales en una universidad mexicana. Los resultados (...) evidencian que las ayudas más requeridas giran en torno al factor socioemocional del aprendizaje. (shrink)
