The liar paradox is a famous and ancient paradox related to logic and philosophy. It shows it is perfectly possible to construct sentences that are correct grammatically and semantically but that cannot be true or false in the traditional sense. In this paper the authors show four approaches to interpreting paradoxes that illustrate the influence of: the levels of language, their belonging to indeterminate compatible propositions or indeterminate propositions, being based on universal antinomy and the theory of dialetheism.

By justification we understand what makes a belief epistemologically viable: generally this is considered knowledge that is true. The problem is defining this with a higher degree of precision because this is where different conflicting conceptions appear. On the one hand, we can understand justification as what makes it reasonable to acquire or maintain a belief; on the other, it is what increases the probability that the belief is true. This work tries to prove that beliefs depend on other beliefs (...) that are epistemically justified and that such beliefs are the result of (i.e., they arise from) our privileged intuition of reality. For this, we examine the concept of epistemic regress. Epistemic reasons authorize a proposition P to be the conclusion of an argument in which such reasons function as premises and are vulnerable to epistemic regress. The three most important approaches to epistemic regress are Infinitism, Coherentism and Foundationalism. (shrink)

Human language has the characteristic of being open and in some cases polysemic. The word “infinite” is used often in common speech and more frequently in literary language, but rarely with its precise meaning. In this way the concepts can be used in a vague way but an argument can still be structured so that the central idea is understood and is shared with to the partners. At the same time no precise definition is given to the concepts used and (...) each partner makes his own reading of the text based on previous experience and cultural background. In a language dictionary the first meaning of “infinite” agrees with the etymology: what has no end. We apply the word infinite most often and incorrectly as a synonym for “very large” or something that we do not perceive its completion. In this context, the infinite mentioned in dictionaries refers to the idea or notion of the “immeasurably large” although this is open to what the individual’s means by “immeasurably great.” Based on this linguistic imprecision, the authors present a non Cantorian theory of the potential and actual infinite. For this we have introduced a new concept: the homogon that is the whole set that does not fall within the definition of sets established by Cantor. (shrink)

With the arrival of the nineteenth century, a process of change guided the treatment of three basic elements in the development of mathematics: rigour, the arithmetization and the clarification of the concept of function, categorised as the most important tool in the development of the mathematical analysis. In this paper we will show how several prominent mathematicians contributed greatly to the development of these basic elements that allowed the solid underpinning of mathematics and the consideration of mathematics as an axiomatic (...) way of thinking in which anyone can deduce valid conclusions from certain types of premises. This nineteenth century stage shares, possibly with the Heroic Age of Ancient Greece, the most revolutionary period in all history of mathematics. (shrink)

The importance of mathematics in the context of the scientific and technological development of humanity is determined by the possibility of creating mathematical models of the objects studied under the different branches of Science and Technology. The arithmetisation process that took place during the nineteenth century consisted of the quest to discover a new mathematical reality in which the validity of logic would stand as something essential and central. Nevertheless, in contrast to this process, the development of mathematical analysis within (...) a framework that largely involves intuition and geometry is a fact that cannot go unnoticed amongst the mathematics community, as we shall show in this paper through the research made by Bernhard Riemann on complex variables.

It is well known the harmful effects that savage capitalism has been causing to the environment since its introduction in a sphere in which a different logic and approach to nature are the essential conditions for the maintenance of the ecosystem and its complex relations between humans and non-human organisms. The amazon rainforest is a portion of the planet in which for thousands of years its human dwellers have been interacting with nature that it is understood beyond its physical condition. (...) Thus, to what extent Amazonian’s approaches to nature could be considered as a moral philosophy through which the way of conceptualizing nature and its non-human denizens enhances the continuity of life and the intimate relations between entities? To answer this question, I will explore the cosmological system of the Shuar of the Ecuadorian Amazon with whom I lived for 5 months between July and November 2018, and thereby elucidate the spiritual relations that this society has with the metaphysical domain of nature.

Recent trends towards an e-Science offer us the opportunity to think about the specific epistemological changes created by computational empowerment in scientific practices. In fact, we can say that a computational epistemology exists that requires our attention. By ‘computational epistemology’ I mean the computational processes implied or required to achieve human knowledge. In that category we can include AI, supercomputers, expert systems, distributed computation, imaging technologies, virtual instruments, middleware, robotics, grids or databases. Although several authors talk about the extended mind (...) and computational extensions of the human body, most of these proposals don’t analyze the deep epistemological implications of computer empowerment in scientific practices. At the same time, we must identify the principal concept for e-Science: Information. Why should we think about a new epistemology for e-Science? Because several processes exist around scientific information that require a good epistemological model to be understood. (shrink)

Tradicionalmente la conceptualización del tópico persona se ha circunscrito a ámbitos como la teología, la filosofía o la antropología. Sin embargo, la incorporación del tópico a gran parte de los textos de naturaleza política, así como en las declaraciones de derechos y tratados internacionales adoptados a partir de la II Guerra Mundial ha supuesto la constitucionalización del mismo. Consecuentemente, como término constitucional su interpretación queda a merced de los actores jurídicos designados para ello en el sistema político constitucional. Es por (...) ello, que, con el fin de determinar el contenido de significado actual del tópico ha de atenderse a las sentencias que interpretan la norma fundante. En este artículo, centramos nuestro estudio en la jurisprudencia del Tribunal Constitucional Español. Esto nos permite poner de relieve el concepto de persona en ellas contenido: su alcance y sus limitaciones. (shrink)

Este artículo se propone mostrar que el significado de aisthesis para Protágoras responde al uso y significación de la filosofía jónica, esto es, aún significa indistintamente juicio, sensación, emoción, creencia, en fin, doxa. Esto tiene una consecuencia muy relevante para la comprensión del homo mensura y la tesis que afirma: aisthesis es episteme.

Based on a discussion of the theoretical contributions of Claude Lévi-Strauss and Pierre Clastres, this article explores social relationships as more than a human dimension. Though strongly analysed by both anthropologists, these relationships appear to involve indigenous societies’ whole ecological and cosmological system. In this sense, reciprocity, social cohesion, and exchange can be understood as material and immaterial interrelationships between entities of a more than a corporeal world. I argue, then, that to go beyond the mere anthropocentric conceptualisation of sociality (...) in a nature good to think, we need to holistically conceive the interconnected levels of trophic, socio-structural and socio-cosmic relationships and exchanges between human and non-human beings in the ecosystem.

The outbreak of SARS-CoV-2 has threatened ethnographic inquiry, undermining its quintessential characteristic. Participant observation, then, has been thoroughly dismembered by the radical measures implemented to prevent the spread of the virus. This phenomenon, in short, has dragged anthropologists to a liminal state within which ethnography is paradoxically caught in an onto-epistemological unstable vortex. The question of being here and not there, during the pandemic, is epitomised in the instability of different spatio-temporal contexts that overlap through technological mediations. Reflecting on previous (...) fieldwork experiences and current virtual inquiries with the Shuar of the Ecuadorian Amazon unfolds how COVID-19 has thoroughly reshaped how the author approaches subjects' socio-ecological settings. Against this background, the article argues that corporeal immersion remains a necessary condition for the anthropological scrutiny of multispecies relationalities amidst the challenging times of the Anthropocene. The article nevertheless demonstrates that the intellectual efforts to grasp the different material temporalities of virtual spaces embrace the ethical principles concerning the renunciation of fieldwork with vulnerable communities. Furthermore, a reflective and speculative stance is proposed to actualise the snapshots of faraway physicalities linking them to past embodied and multi-sensory experiences. It is ultimately theorised how these mnemonic devices operate as creative forms of inquiry that overcome the pandemic consequences, extra-stimulating our cognitive capabilities to reflect on prior and possible socio-material interactions.

Al tratar de disolver la neta separación entre una mente racional y la materia inerte abogada por el dualismo Cartesiano, el monismo lucha por reunificar estas distintas realidades ontológicas. Tal como para Claude Lévi-Strauss y Baruch Spinoza, esa dicha unificación no puede prescindir de la trascendencia de la mente humana como locus del pensamiento y conocimiento de la naturaleza externa. A través de una discusión entre las abstracciones de la etnología Amerindia (animismo-perspectivismo), las teorizaciones del estructuralismo y las relaciones que (...) estos tienen con algunas especulaciones filosóficas occidentales, este artículo trata de analizar las intricadas interacciones humano-naturaleza entre los Shuar de la Amazonía Ecuatoriana. De esta forma, se argumenta que las realidades metafísicas de las experiencias oníricas y visionarias están ontológicamente determinadas por el grado de intensidad de contacto que los humanos establecen con las subjetividades materiales del ecosistema.

The question around foreigners and their obligation to respect and fulfil the national - or civil - norms of the territory where they are; has become due the migration and multicultural movements once again a key one. Addressed by a multitude of authors along the centuries, the question has been answered based on the different placements around juridical and political concepts like citizenship, sovereignty, authority or law. In this investigation, the doctrinal development carried out around the obligatory nature of the (...) civil norm for foreigners in Spanish scholasticism is going to be considered. Specifically, due to its thoroughness and depth, the doctrine done by Francisco Suarez is going to be critically analysed. Once the answer given in our author's doctrine to the question posed has been established, we will consider the possible influences in the Anglo-Saxon sphere. (shrink)

The purpose of this paper is to present several applications of combinatorial principles, well-known in Set Theory, to the geometry of infinite dimensional Banach spaces, particularly to the existence of certain basic sequences. We mention also some open problems where set-theoretical techniques are relevant.

The figure of chiasmus, which plays a key role inside Merleau-Ponty’s thought, makes it possible to address the way Castoriadis defines the imaginary throughout his entire work from a new perspective, as well as to shed light on some complexities concerning the relation between instituted and instituting. Tthis article emphasizes the intertwining of three pair of concepts, each of which corresponds to a different but yet interrelated aspect of his philosophy: psyche-society, tradition-innovation, and autonomy-heteronomy.

In this article, I will outline an assessment model that allows instructors to continuing assigning term papers and argumentative papers without compromising the authenticity of student assessment. This path forward relies upon a pseudo flipped classroom model in which students will complete a scaffolded term paper through a series of in-class assessments that build upon previously completed components. The final steps of completing this assignment will require producing a draft and final version of a traditional term paper outside of the (...) classroom but only after the instructor ensures they have critically thought through the preceding components independently. The intention is to maintain the nuance, critical thinking, engagement with primary and secondary sources, and depth of content comprehension that a thoughtful paper requires, while also ensuring that students are completing the work themselves and not merely outsourcing bits and pieces of it to LLMs. (shrink)

Formas de representación de la violencia en El vuelo del tigre y Libro de navíos y borrascas de Daniel Moyano.

García Bacca inicia en 1936 un proyecto de filosofía actual, que marca la dirección del resto de su obra. Al giro copernicano añade una interpretación de la comprensión como “función trascendental de los sentimientos”. Propongo entender, en primer lugar, estas tesis como el núcleo duro del lugar hermenéutico desde el que García Bacca dialoga con Heidegger; y este diálogo, presente en su obra explícitamente hasta 1985, no como una interpretación al uso sino como ejemplo de su propia la práctica del (...) filosofar. En segundo lugar este artículo analiza la estrategia teórica de García Bacca, que propone una nueva ontología, de base antropológica, y conecta lo actual en filosofía con los cambios habidos en la fundamentación de las ciencias y las profundas modificaciones históricas. Un lugar especial ocupa el análisis del desmontar como modo de proceder constructivista y crítico de la filosofía actual que opone García Bacca al programa heideggeriano de destrucción de la metafísica.

In this study I intend to prove that there is a close connection between ethical purposes of Environmental Philosophy as World Philosophy and the idea of sacred nature as part of the “world” in a phenomenological sense, which includes sacred space as defined in the philosophy of religion. The main points that intersect here are: the idea of sacred space; the perception of virtue in a sacred world; the beauty of creation: nature, life, human sensibility. The theoretical background of this (...) study contains points of view that express phenomenological, hermeneutic, theological, and aesthetic conceptions belonging to authors and exegetes such as Mircea Eliade, William E. Paden, David Cave, Ion Ianoși, Douglas Allen, Arnold Berleant, and Vincent Blok. I believe that the neglect of the environment-as-a-condition-of-life (the consequences of which can already be seen in ecological imbalances) is caused by, among other factors, the desacralization of human attitudes towards nature and the world of life. Few people still have a feeling of sacred nature or the aesthetic emotion of perceiving beauty in natural forms. The relationship with the environment and nature is reduced to its exploitation as a source of economic profit or as a way for spending free time, a source of personal comfort devoid of any spiritual significance. Surely we cannot go back to archaic religions or medieval Christianity, but we can reintegrate into our moral values something of those cultures’ admiration and respect for the beauty/sublimity of nature and the world as expressions of divine creation, as something sacred. Philosophical debates related to this retrieval and their dissemination could be part of solving the ecological problems of the contemporary world. (shrink)

En 1919, la même année où Jean Giraudoux fait son « Adieu à la guerre », il écrit « Les morts d’Elpénor ». En 1926, à côté de trois autres histoires, ce texte intégrera le corps d’Elpénor, déterminant l’ensemble, une collection de quatre textes écrits pendant dix-huit ans, le premier étant « Cyclope », écrit en 1908 ; le deuxième, « Sirènes », en 1912 ; le troisième en 1919 ; et le dernier en 1926, « Les nouvelles morts d’Elpénor (...) ». Quand « Cyclope » et « Sirènes » sortent respectivement chez Le Matin en 1908 et chez Paris-Journal en 1912 aucun d’entre eux ne mentionne Elpénor. Bref, c’est avec le développement des deux dernières histoires, que Elpénor, cette figure effacée chez Homère et absente dans les deux premiers textes de Giraudoux, vole la vedette. Cet article voudrait montrer comment la mise à jour du héros et de ses histoires est en dialogue avec la guerre vécue par l’auteur, pour proposer comment les vieilles histoires, lorsqu’elles sont renouvelées, participent à un processus qui leur permet d’élaborer les défis du présent, communiquant le présent, à travers un code déjà public, l’Odyssée.

Este artículo analiza lo que nos cuentan las imágenes fotográficas en su reverso y en las huellas del verso, a través de las anotaciones, marcas o descripciones que contienen, que entregan información importante de su contexto de producción, de los sujetos u objetos fotografiados y de su trayectoria. Así, se configura un sentido apropiado de la imagen. Este artículo, pone el foco en imágenes fotográficas escolares porque representan un espacio de convivencia particular y de intercambio de experiencias que, en alguna (...) medida, se captura y resguarda en ellas. En los pliegues, en los bordes oscurecidos o desgastados, en los márgenes marchitos y en las marcas de óxido o de otros materiales, es posible también encontrar historias, restos de memorias, afectos y rostros en un contrapunto que va más allá de la motivación del fotógrafo para captar el instante en un encuadre específico. Para el análisis, se presentan algunas imágenes fotográficas pertenecientes al archivo escolar de un centro educativo de la ciudad de Talca en la región del Maule (Chile), pues permiten develar el significado familiar, mnemónico y comunitario que estas adquieren al reunirse en ese repertorio. Este valor igualmente se desprende de la observación del material oculto en el reverso y de las marcas del verso de las imágenes fotográficas. (shrink)

Type 2 diabetes has been considered a public health threat due to its growing prevalence, particularly in the older population. It is important to know the effects of psychosocial stress and its potential consequences for some basic cognitive processes that are important in daily life. Currently, there is very little information about how people with T2D face acute psychosocial stressors, and even less about how their response affects working memory, which is essential for their functionality and independence. Our aim was (...) to characterize the response to an acute laboratory psychosocial stressor and its effects on WM in older people with T2D. Fifty participants with T2D from 52 to 77 years old were randomly assigned to a stress or control condition. Mood and physiological responses to tasks were measured. In addition, participants completed a WM test before and after the stress or control task. Our results showed that the TSST elicited higher negative affect and greater C and sAA responses than the control task. No significant differences in WM were observed depending on the exposure to stress or the control task. Finally, participants who showed higher C and sAA responses to the stressor had lower WM performance. Our results indicate that medically treated older adults with T2D show clear, typical mood and physiological responses to an acute psychosocial stressor. Finally, the lack of acute psychosocial stress effects on WM suggests that it could be related to aging and not to this disease, at least when T2D is adequately treated. (shrink)

Optando por la retórica, Las Casas busca un modelo antropológico nuevo, distinto tanto del humanismo elitista, como del erasmismo voluntarista. En esta búsqueda quisiéramos poner énfasis, argumentando a favor de un resultado revolucionario a la luz de sus objetivos prácticos: cesar el homicidio y garantizar la libertad a los indios en cada aspecto de su vida. Desde aquí, nos referiremos a esta postura revolucionaria que bebe de Aristóteles y de santo Tomás, pero que es capaz de superarlos, a favor de (...) una defensa de lo propiamente humano, que estriba precisamente en reconocer que todas las comunidades tienen la posibilidad de realizarse autónomamente. Por esto, creemos que se puede hallar, en Bartolomé de las Casas, una importante contribución a la cuestión del reconocimiento, pero aún más, un importante punto de partida para los desafíos de una filosofía intercultural.

Should Lesbian and women's events have policies banning sadomasochists or sadomasochistic acts? This question is being heatedly debated in the Lesbian community. In this paper, I examine the moral and political problems with sadomasochism from a Lesbian-feminist perspective, concluding that sadomasochism is antifeminist and antiliberatory for many reasons. Then, given this conclusion, I explore how events such as women's music festivals should determine their policies about sadomasochism.
