We study the origin of quantum probabilities as arising from non-Boolean propositional-operational structures. We apply the method developed by Cox to non distributive lattices and develop an alternative formulation of non-Kolmogorovian probability measures for quantum mechanics. By generalizing the method presented in previous works, we outline a general framework for the deduction of probabilities in general propositional structures represented by lattices (including the non-distributive case).

The Ashtavakra Gita is an ancient Indian text from the classic Vedanta period.

El presente artículo pretende mostrar cómo la descripción fenomenológica que el filósofo francés Jean-Luc Marion hace del fenómeno saturado encaja con precisión en la cristología característica del cuarto Evangelio. A partir del pensamiento de este autor, concluiremos que Jesucristo, como manifestación visible del Dios invisible, concentra en sí las cuatro paradojas fenoménicas, apareciendo también según el relato joánico como una “paradoja de paradojas” o como un “fenómeno saturado por excelencia”.

Esta publicación tiene por objeto situar las coordenadas de ciencia, tecnología, naturaleza y cultura en el estado del mundo a las puertas del tercer milenio y discutir las perspectivas y los retos con los que previsiblemente se va a encontrar nuestro futuro, así como analizar posibilidades de intervenir adecuadamente en el mismo.

El artículo expone la contraposición entre dos posiciones filosóficas (deconstrucción y reconstrucción), dos autores (Jacques Derrida, Jean Luc Ferry) y dos libros (Apprendre à vivre enfin, Apprendre à vivre). En última instancia, dos formas de entender las relaciones entre filosofía y vida. Más allá del logocentrismo, objeto de la deconstrucción, el biocentrismo es el eje de la tarea de reconstrucción de una filosofía articulada como ontología o teoría de lo real, filosofía moral o teoría de la justicia y sabiduría o (...) teoría de la salvación. En suma, una forma renovada de asumir la necesidad de la filosofía. (shrink)

The debate around “strong” paraconsistency or dialetheism (the view that there are true contradictions) has – apart from metaphysical concerns - centred on the questions whether dialetheism itself can be definitely asserted or has a unique truth value, and what it should mean, if it is possible at all, to believe a contradiction one knows to be contradictory (i.e. an explicit contradiction). And what should it mean, if it is possible at all, to assert a sentence one knows to be (...) contradictory? (shrink)

The paper investigates the crisis of Portugese agriculture and the challenges connected with Portugal's integration into the European Economic Community (EEC). An historical overview of the economic and social development of the agricultural sector since the 1950s is provided. Additionally, a discussion of the principal differences between the Portugese agricultural crisis and that of other advanced European countries and the U.S. is carried out. In this portion of the paper it is argued that agriculture in Portugal is characterized by low (...) levels of productivity and production which contrast with the high levels of productivity and overproduction of other European and North American countries. Finally, an analysis of the possible future consequences of Portugal's further integration into the EEC is provided. (shrink)

Due to the hyperspecialization so prevalent nowadays, interdisciplinary research is a demanding kind of epistemic activity. The concept of intellectual virtue as presented by responsibilist approaches of virtue epistemology could offer an effective counterweight to this challenge but raises the question of what epistemic virtues are necessary for interdisciplinarity. Based on a qualitative study, we identify and heuristically conceptualize a relevant subset of epistemic virtues required by interdisciplinarity that we call _interpersonal intellectual virtues. _These virtues are personal character traits that (...) facilitate the reciprocal acquisition and distribution of knowledge _with_ and _through_ other people. By their very nature, they are only exercised in an interpersonal relationship that seeks an epistemic good, so in some sense, they are at the intersection of social virtues and intellectual virtues. We use Jason Baehr’s four-dimensional proposal for the essential components of intellectual virtues (motivational, affective, skill, and judgment) to show that these interpersonal traits are indeed epistemic virtues. Some examples of interpersonal intellectual virtues are intellectual empathy, intellectual respect, and intellectual trust, among others. Intellectual empathy is a paradigmatic case that we analyze in more detail. Finally, we suggest that interpersonal intellectual virtues are the key character traits of people involved in any successful collective epistemic endeavor, interdisciplinary research being a privileged context in which we can clearly see their manifestation.

The study and understanding of fundamental questions cannot be addressed by a single discipline. A plurality of insights needs to be integrated or coordinated to allow for mutual enrichment in interdisciplinary research. The intellectual character describes the set of dispositions that both configure and motivate intellectual behavior. In this paper, we explore the intellectual virtues that constitute the ideal character of an interdisciplinary researcher. We look at dimensions of several intellectual virtues – intellectual curiosity, open-mindedness, intellectual humility, and intellectual honest (...) – relevant to interdisciplinarity, we discuss the significance of other character traits – intellectual creativity and intellectual trust – for integrating a plurality of insights, and we argue for the need of a social cognition approach, emphasizing the relevance of interpersonal intellectual virtues in interdisciplinary inquiry. All these virtues are key constituents of the intellectual character of interdisciplinary researchers. (shrink)

Different authors of Fregean inspiration have argued recently for the need of resorting to senses in order to explain successful communication. Such arguments have led some philosophers to develop theories of sense which include some of the externalist insights brought up by neo-Russellians. In this paper, we argue that these theories of sense don't work. We also present a broadly neo-Russellian account that explains away Fregean puzzles on communication without resource to entities like senses.

This essay takes up the question of a “new” social paradigm by first examining the recent emergence of the U.S. Occupied Movement (OM) as a provocative and inspiring moment of political re-composition, but one that also narrates a more complex unraveling of what W.E.B Du Bois called “democratic despotism.” The most recent political tensions and economic “crisis” of the global north point to the disruption of a white “middle class” hegemony alongside inspiring moments of reconstructed conviviality. I suggest that the (...) tension within spaces of occupation and convergence are animated by conviviality that should be read “politically” by noting the emergence of tools in service of community regeneration. Towards that end, I introduce Universidad de la Tierra Califas, a local project somewhere in-between network and collective pedagogies that is also a project of strategic conviviality and a Zapatismo beyond Chiapas. I argue that UT Califas engages a collective subject as part of an epistemological struggle inspired by Indigenous autonomy currently underway throughout Latin America. (shrink)

Entre los estudios tradicionales sobre la noción de trabajo enlos Padres de la Iglesia, de talante apologético, y los análisis delmundo del trabajo en el Imperio existe una notable diferencia. Losprimeros afirman que el cristianismo trajo una concepción positivadel trabajo, y los segundos, minimizan la influencia del cristianismoen el modo en que los antiguos valoraban el trabajo. Una lecturaatenta de los textos más significativos muestra que las influenciasfueron mutuas y que, al modificarse con el paso del tiempo lascondiciones sociales, se (...) produjo una evolución de las posicionesadoptadas por unos y otros.
