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.

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)

Pese a los esfuerzos de las últimas décadas, la poca habilitación tecnológica dentro de las escuelas rurales de México ha quedado expuesta durante el cierre de escuelas por Covid-19. Se realizó un estudio exploratorio para identificar los niveles de brecha digital de acceso experimentados por los profesores de un centro educativo en una zona rural de México y explorar las estrategias de usos de las TIC desplegadas para dar continuidad académica durante la pandemia. 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)

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)

El artículo busca discutir algunos de los posicionamientos de Heidegger en su época nazi, mostrando que la base de su error político está en su nacionalismo. Esto lo ha hecho caer en una interpretación de la historia de Alemania como una opción opuesta a la modernidad y lo ha inducido a perder de vista las relaciones de interdependencia mutua entre facticidad y trascendencia. El nacionalismo se presenta así como un desvío del propósito universalista de la filosofía y el error de (...) Heidegger como un abandono del propósito esencial de la filosofía. We discuss some aspects of Heidegger's stance during his nazi period. We show that the root of his political error lies in his nationalism. This led him to understand the history of Germany as an option opposed to modernity, while losing sight of the mutual dependence of facticity and transcendence. Nationalism appears thus as a deviation from the universalist aim of philosophy and Heidegger's error as defection from philosophy's essential purpose. (shrink)

Whether nature is valuable on its own (intrinsic values) or because of the benefits it provides to humans (instrumental values) has been a long-standing debate. The concept of relational values has been proposed as a solution to this supposed dichotomy, but the empirical validation of its intuitiveness remains limited. We experimentally assessed whether intrinsic/relational values of sentient beings/non-sentient beings/ecosystems better explain people’s sense of moral duty towards global nature conservation for the future. Participants from a representative sample of the population (...) of Singapore (n = 1508) were randomly allocated to two “the last human” scenarios. We found that the best predictor of such a sense of moral duty for future nature conservation is the recognition of the intrinsic values of sentient beings. Our results suggest that the concern for animal welfare may enhance rather than compete with the sense of moral duty towards nature conservation. (shrink)

La educación del hombre es un tema que no deja de ser cuestionado. A pesar de los esfuerzos y de las diversas innovaciones en la materia, la crisis educativa de la «sociedad líquida» es cada vez más profunda y al mismo tiempo más relativa. El hombre y sus actitudes, hoy fuertemente controvertidas por sus manifestaciones de violencia, irracionalidad, corrupción y rechazo de los valores, revelan la cruda realidad educativa. Frente a la situación descrita, la presente investigación se propone analizar las (...) raíces de esta problemática y a la vez proponer reflexiones y alternativas innovadoras que ayuden a superar dicha crisis. Los resultados encontrados son reveladores y esperanzadores. Varios de los planteamientos de este trabajo ya están contemplados en la legislación y en la teoría educativa desde hace varias décadas; sin embargo, han quedado en el olvido por efectos del individualismo, la anomia, el escepticismo y el nihilismo propios de la sociedad posmoderna. El aporte factible y necesario es la educación sistémica de la persona que, superando los diversos reduccionismos, se centre en el «desarrollo humano integral» ; dejando en claro, asimismo, los roles de la familia, del Estado, de la escuela, de los medios de comunicación social, de la sociedad y del mismo educando frente al desafío de la educación actual.

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.

La estela de la crisis del proyecto civilizatorio occidental ha agudizado las desigualdades sociales y alterado los procesos homeostáticos de la biosfera. El despojo sutil o violento de los territorios con alto potencial de recursos naturales es una astucia más del modelo neoliberal para paliar su crisis estructural; tal como sucede contra los pueblos indígenas. Estas acciones son altamente perturbadoras de las dinámicas de organización social, y de la agudización de injusticia ambiental. Sin embargo, diversos grupos sociales están reconfigurando sus (...) estrategias no solo para resistir, sino para la construcción de alternativas. El ethos comunitario (comunalidad) -como un elemento cultural propio de los pueblos con ascendencia de la cultura mesoamericana- es una de estrategia intercultural fundamental para estas tareas. La noción de resiliencia social se usa como herramienta analítica de tal exploración. Se destaca que los grados de resiliencia de las comunidades están relacionados con la construcción de procesos autonómicos. (shrink)

We provide a model in which students must choose whether or not to cheat on a course exam. By assuming that the moral cost of acting dishonestly decreases as the number of other people who behave in the same way increases, our model explains one important channel by which unethical behavior of other individuals can influence observers’ behavior. Through the use of the Global Games approach of equilibrium selection, we build a framework that provides the micro-foundations of peer effects on (...) academic dishonesty and shows how better student technology of cheating and higher disutility of effort make the cheating equilibrium more likely to be selected. By extending the model, we find that the peer effect strength is not affected by the level of homogeneity of the cohort, but decreases in the size of the class. Our approach may be seen as an important step towards reduced-form models of peer effects on dishonest behavior. (shrink)

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of QmbC, (...) the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)

From the early to mid-1970s, Michel Foucault posited that power consists of a relation rather than a substance and that this relation is comprised of unequal forces engaged in a warlike struggle against each other, resulting invariably in the domination of some forces over others. This understanding of power, which he retrospectively dubbed `Nietzsche's hypothesis' and `the model of war', underpinned his well-known analyses of disciplinary power. Yet, Foucault in his Collège de France course from the academic year 1975-6, `Society (...) Must Be Defended', suddenly began to call into question this understanding and his doubts about it did not abate well into the late 1970s. In this article, we suggest that his militant politics in the early 1970s sustained his adherence to the war model and that his more cautious political attitude later in the decade underpinned his suspicions about this model. Key Words: biopolitics • Henri de Boulainvilliers • Michel Foucault • Thomas Hobbes • militancy • F. W. Nietzsche • politics • power • race • war. (shrink)

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces naturally a (...) non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

In 1986, Mikenberg et al. introduced the semantic notion of quasi-truth defined by means of partial structures. In such structures, the predicates are seen as triples of pairwise disjoint sets: the set of tuples which satisfies, does not satisfy and can satisfy or not the predicate, respectively. The syntactical counterpart of the logic of partial truth is a rather complicated first-order modal logic. In the present article, the notion of predicates as triples is recursively extended, in a natural way, to (...) any complex formula of the first-order object language. From this, a new definition of quasi-truth is obtained. The proof-theoretic counterpart of the new semantics is a first-order paraconsistent logic whose propositional base is a 3-valued logic belonging to hierarchy of paraconsistent logics known as Logics of Formal Inconsistency, which was proposed by Carnielli and Marcos in 2002.

La cuestión de la relación del hombre con la naturaleza ha sido abordada desde múltiples ópticas a lo largo de la historia del pensamiento. Se ofrece en este artículo la propuesta de los pensadores Hans Jonas y Helmuth Plessner quienes sitúan al hombre enraizado en el dinamismo natural, acentuando, con Jonas, su responsabilidad moral con y sobre este.

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

A ideia de uma crise do rádio consolidou-se no imaginário coletivo nas últimas décadas, a despeito de não haver ancoragem na realidade. Se muitas rádios tradicionais AM e FM saem do ar, vendidas a igrejas eletrônicas ou novos grupos empresariais, multiplica-se a oferta de conteúdos no contexto de um rádio expandido, que transborda para novas plataformas e é consumido nos mais diversos dispositivos. O rádio vai bem, obrigado, embora algumas emissoras de rádio em ondas hertzianas estejam mal das pernas, lamentando-se (...) da concorrência com serviços on-line e da erosão dos habituais índices de audiência, antes medidos em centenas de milhares de ouvintes por minuto.
