Classical propositional logic plays a prominent role in industrial applications, and yet the complexity of this logic is presumed to be non-feasible. Tractable systems such as depth-bounded boolean logics approximate classical logic and can be seen as a model for resource-bounded agents whose reasoning style is nonetheless classical. In this paper we first study a hierarchy of tractable logics that is not defined by depth. Then we extend it into a modal logic where modalities make explicit the assumptions discharged in (...) propositional proofs, thereby expressing blueprints for proofs. A natural deduction system is provided that permits to reason about and manage such proof blueprints. (shrink)

Popper conceived an experiment whose analysis led to a result that he deemed absurd. Popper wrote that his reasoning was based on the Copenhagen interpretation and therefore invalidated it. Many authors who have examined Popper's analysis have found in it various technical flaws which are briefly summarized here. However, the aim of the present article is not technical. My concern is to redress logical flaws in Popper's argument: the terminology he uses is ambiguous, his analysis involves counterfactual hypotheses, and it (...) violates Bohr's complementarity principle. Therefore, the absurdity of Popper's result only confirms Bohr's approach. (shrink)

La utilización de las nociones de “conservador” y “progresista” en las ciencias sociales (y en la opinión pública) ha llegado a configurar dos ideologías políticas. En este número se tratan, a partir de Kant, diversos sentidos de tales nociones en el contexto actual: la perspectiva de la Economía constitucional de Buchanan, la concepción de la sociedad abierta de Popper, la teoría de la justicia de Rawls y la concepción filosófica de la vida social y política de Ortega y Gasset.

Ensayo sobre la comunicación epistemológica de la razón filosófica y la razón jurídica a la luz del realismo clásico.

En este artículo describiremos la vitalidad del sistema fonológico del mapudungun hablado por escolares pewenches de la Provincia del Biobío, VIII Región. Específicamente, nos hemos propuesto: a) Determinar los fonos/fonemas, y su fonotaxis, que se relevan como indicadores de vitalidad, b) Identificar las transferencias fonético-fonológicas presentes en la fonología del pewenche hablado por estos escolares y c) Interpretar las transferencias encontradas en términos del grado de vitalidad de la fonología de la lengua. La muestra está conformada por un grupo de (...) 20 escolares bilingües de entre 12 y 15 años de edad, que se encuentran cursando 7° y 8° año básico en escuelas rurales pertenecientes a dos comunidades pewenches del valle del Queuco, en la comuna de Alto Biobío. Para la recolección del material fonológico, se aplicó a los participantes una lista léxica de 65 ítems, material que se complementó con la narración oral en mapudungun de un cuento. Según nuestros datos, hemos podido constatar la existencia de una serie de rasgos fónicos en el mapudungun hablado por los escolares pewenches que obedece a la influencia de las estructuras fonológicas del castellano. Sin embargo, el grado y la difusión de los fenómenos de transferencia se desarrollan de manera heterogénea en ambas comunidades en estudio, debido, entre otros factores, a la intensidad del contacto. In this article we will describe the vitality of the phonological system Mapudungun spoken by Pewenche schoolchildren from the Biobío province, VIII Region. We intend: a) To determine the phones/phonemes, and their phonotactics, which are revealed as vitality markers. b) To identify the phonetic-phonological transferences which are present in the Pewenche spoken by these schoolchildren, and, c) To interpret the transferences found in terms of the degree of the language phonological vitality. The sample is composed of 20 bilingual schoolchildren from 12 to 15 years old, who are in 7th and 8th grade in rural primary schools belonging to two Pehuenche comunities from Valle del Queuco, in the city of Alto Biobío. To collect the phonological material, we applied a 64-item lexical list, which was complemented with the oral narration of a tale in Mapudungun. According to our data, we have been able to verify the existence of a series of phonic features in the Mapudungun spoken by Pewenche schoolchildren, which originate because of the influence of the Spanish phonological structure. However, the degree and spread of the transference phenomena develop in a heterogeneous way in both of the studied communities. due to the contact intensity, among other possible factors. (shrink)

Se realizó una investigación con el objetivo de elaborar actividades que relacionan los elementos teóricos con la práctica desde la asignatura Defensa Civil, para contribuir a la participación de estudiantes universitarios y habitantes de la comunidad "Los Coquitos" en la prevención, mitigación o solución de los problemas ambientales que la afectan. Se aplicó un pre-experimento que permitió comprobar la efectividad de las actividades desarrolladas. Esta propuesta favoreció la vinculación de la escuela con la comunidad desde la protección del medio ambiente. (...) A research was carried out with the aim of designing tasks that relate theoretical elements with the practice in Civil Defense to contribute to the participation of university students and inhabitants of Los Coquitos community in the prevention, lessening or solution of the environmental problems it faces. A pre-experiment was applied which allowed to test the effectiveness of these tasks. This proposal favored the relation between the school and the community taking into account the environmental protection. (shrink)

En este artículo, estudiaremos la concepción de la verdad en Gilles Deleuze, a partir de su estrecha conexión con las fuerzas reales que producen el pensamiento. Primeramente, rastrearemos algunas claves de la crítica deleuzeana a la representación, centrándonos en su lectura de la filosofía platónica y en su oposición a la “imagen dogmática del pensamiento”. La forma de pensar representativa deriva en una determinada concepción de la verdad, a la que Deleuze se opone radicalmente. Como veremos, no se tratará de (...) negar lo verdadero, sino de ligarlo con una “verdad de la verdad” que determina su valor según las múltiples fuerzas del pensamiento. A modo de conclusión, se distinguirán tres sentidos en la noción deleuzeana de verdad, y se pondrá en duda la suficiencia de los criterios propuestos por su pensamiento para distinguir entre las fuerzas y formas de vida que están detrás de toda verdad.

El fraile capuchino Antonio de Fuentelapeña escribió en 1676 El ente dilucidado, obra de filosofía escolástica en la que su autor pretende demostrar la existencia de duendes. Sin embargo, la crítica posterior juzgó como extravagancia y locura la obra, sin reparar en que sus argumentos escolásticos analizaron muchos temas filosóficos de extrema importancia, como la racionalidad de los animales, tan en boga hoy día gracias al estudio de la conducta animal comparada, la Etología.

¿Cuál es el sentido del aparente renacimiento del comunismo en la filosofía continental? ¿Hemos de tomarlo en serio, o se trata de una simple moda en el terreno del pensamiento? Esta breve nota señala las viejas y poderosas raíces de esta nueva fascinación y propone una comparación irónica entre los “nuevos filósofos franceses” de la década de 1980 y estos “viejos filósofos franceses” que hoy convergen en el neocomunismo.

The will to escape from the so called Metaphysics of Presence has become a topic in contemporary philosophy. However, this topic is often related to the primacy, in ancient thought, of the actual being, and the correlative evaluation of the potential as an imperfect way of existence. In this text we first analyze the traditional interpretation of the foundations of this primacy in Aristotle’s philosophy, that exhibits a theological form. According to this we explore, in the second part of the (...) article, how the efforts of modern thinkers to build an ontological discourse free from this primacy have produced, in some cases, a kind of Umkehrung resulting in a Metaphysics of Absence that preserves the theological form and results in a primacy of the potential, that is specifically consistent with the Imperium of the Virtual, very illustrative of nowadays conceptions of time, language, power and being. Finally, we essay to offer another interpretation of the primacy of the actual in Aristotle’s Ethics and Metaphysics, which could identify a political philosophy capable to avoid the infertile alternative Presence/Absence in ontology.

Some arguments are presented in this paper where it can be stated that the truth that philosophy seeks is not the truth that matches with the verification interests of knowledge instrumentalization or pragmatism (Rorty) present in contemporary philosophy (Rorty). Aside from the unavoidable reality of human necessities and from the instruments that allow science and technology, as well as its own meaning (thanks to knowledge), which are necessary for human life, it is still a priority to explain a personal, “existential (...) truth” that requires a belief system conversion. This belief system conversion would be the philosophy’s starting point and not a “question about the oblivion of the being” (Heidegger), nor an ethic (Lévinas). (shrink)

Drawing on historical and contemporary evidence from Great Britain and Italy, this article examines actions that fall under official definitions of corruption and actions that are not illegal but are widely regarded as morally corrupt. As a social anthropologist, I argue that when dealing with the complexity of corruption and abuses of power, we need to identify what aspects of the system encourage or generate illicit practices (illegal and legal) and what aspects could instead generate real change. It is imperative (...) to assess the precise identity of the dividing line between the legitimate and the illegitimate and between the legal and the moral, and to address both the exact relationship of the protagonists in public life to formal law and its production and their perceived legitimacy in the broader society. Empirical evidence suggests that the production of the law must take into account the moralities which inform the definition of legitimacy at the grassroots, for legislation that enjoys such legitimacy is authoritative-therefore effective-legislation, and thus is governance that benefits from and abides by such legislation.

This article explores the relationships between legal proof and fundamental epistemic concepts such as knowledge and justification. A survey of the legal literature reveals a confusing array of seemingly inconsistent proposals and presuppositions regarding these relationships. This article makes two contributions. First, it reconciles a number of apparent inconsistencies and tensions in accounts of the epistemology of legal proof. Second, it argues that there is a deeper connection between knowledge and legal proof than is typically argued for or presupposed in (...) the legal literature. This connection is illustrated through a discussion of the Gettier problem in epistemology. It is argued that the gap or disconnect between truth and justification that undermines knowledge in Gettier cases also potentially undermines the success of legal verdicts. (shrink)

La cosmovisión mítica de las sociedades prehispánicas no dio paso a una visión filosófica, como sí sucedió en la sociedad griega. ¿Es viable filosofar hoy desde algún mito precolombino?, la aparente ingenuidad de esta pregunta esconde un conjunto de problemas que es necesario deslindar. En la acepción peyorativa del mito como cuento o historia. ¿Qué es lo que hoy merece convertirse en asunto de una consideración filosófica? Desde Heidegger algunos filósofos entienden que el gran “mito” de la ciencia y la (...) técnica se erige hoy con una pretensión de verdad unilateral que hay que desenmascarar. Sin embargo, el mito en otra acepción tiene como función desocultar lo sagrado, lo originario. Esto es patente en los mitos prehispánicos, el mito da sentido al mundo de la vida. Según Gadamer la razón ilustrada no es la definitiva superación del mito; es acaso “nuestro mito” secular, con sus bondades y sus patologías. Quizá más que superar el mito, sea posible pensarlo como una experiencia que nunca puede dejar de incluir un tipo de racionalidad. (shrink)

Este ensayo expone las ideas fundamentales de la ética pragmática de Rorty, partiendode su crítica de la verdad como representación y la propuesta de la solidaridad en unsentido moral. El autor intenta sentar las bases de una crítica a la ética pragmática yestablece la necesidad de volver a plantear el tema de la persona -desde un cristianismomás “actualizado”- y se formula el problema de la esencia de lo pragmático al interiorde una metafísica que, fundándose un referente simbólico o analógico, supere (...) eldogmatismo y logre inspirar sentimientos como la solidaridad.

Esports have transformed playing video games into a competitive activity that bears similarities to sports and the processes of sportization. Taking as a starting point the concept of sports as competitive games, the objective of this work is to analyse the sportization of esports, as well as the impact of esports on the concept of sports and their implications on sports in the immediate future. Sports and esports are two different realities that interact with each other. This is a conceptual (...) problem for sports, and it also defines a practical challenge in the immediate future of sports. The virtual environment offers new possibilities in sports, such as broadening the possibilities of confrontation and competition development, contributing to reducing the environmental impact of certain sports, improving safety and maintaining the physical integrity of athletes, and increasing social justice and equality of chances in sports competitions. The challenge, therefore, is to try to bring esports and sports closer together, even moving toward hybrid sports, as addressed throughout this article. (shrink)

Se busca rastrear la imagen que Platón tiene de Heráclito y articularla con la estructura argumentativa del Cratilo, para comprender las necesidades textuales a las que responde la doctrina del flujo perpetuo, es decir, la discusión sobre la corrección (ὀρθότης) del nombre. Gracias a la inclusión del testimonio heraclíteo, resulta posible rastrear la presunta consolidación de la tesis sobre los nombres primarios y los secundarios como el eje de la separación entre dos planos de realidad (uno estable y uno móvil) (...) y de la teoría de las Ideas -es decir, como la base de la epistemología platónica presente en los diálogos de madurez-. The article seeks to trace the image Plato has of Heraclitus and connect it with the argumentative structure of the Cratylus in order to understand the textual needs that give rise to the doctrine of perpetual flux, that is, the discussion regarding the correctness (ὀρθότης) of names. The inclusion of Heraclitus's testimony makes it possible to trace the alleged consolidation of the thesis regarding primary and secondary names as the axis of separation between two levels of reality (one stable, the other, changing) and the theory of Ideas -that is, as the basis of Plato's epistemology as set forth in the late dialogues-.
