Daniel Isaacson has advanced an epistemic notion of arithmetical truth according to which the latter is the set of truths that we grasp on the basis of our understanding of the structure of natural numbers alone. Isaacson’s thesis is then the claim that Peano Arithmetic (PA) is the theory of finite mathematics, in the sense that it proves all and only arithmetical truths thus understood. In this paper, we raise a challenge for the thesis and show how it can be (...) overcome. We introduce the concept of purity for theories of arithmetic: a theory of arithmetic is pure when it only proves arithmetical truths. Then, we argue that, under Isaacson’s thesis, some PA-provable truths—including transfinite induction claims for infinite ordinals and some consistency statements—are seemingly not arithmetical in Isaacson’s sense, and hence that Isaacson’s thesis might entail the impurity of PA. Nonetheless, we conjecture that the advocate of Isaacson’s thesis can avoid this undesirable consequence: the arithmetical nature, as understood by Isaacson, of all contentious PA-provable statements can be justified. As a case study, we explore how this is done for transfinite induction claims with infinite ordinals below ε0. To this end, we show that the PA-proof of such claims employs exclusively resources from finite mathematics, and that ordinals below ε0 are finitary objects despite being infinite. (shrink)

This paper is concerned with the claim that supervaluationist consequence is not classical for a language including an operator for definiteness. Although there is some sense in which this claim is uncontroversial, there is a sense in which the claim must be qualified. In particular I defend Keefe's position according to which supervaluationism is classical except when the inference from phi to Dphi is involved. The paper provides a precise content to this claim showing that we might provide complete (and (...) sound) systems of deduction for supervaluationist consequence in which proofs are completely classical with the exception of a single last step (involving the above mentioned inference).

La primera cuestión a plantear en la resolución de conflictos es la percepción que las partes tienen de éste. Nos centraremos en el análisis del caso «0», en el cual las partes, o al menos una de ellas, no percibe o se niega a percibir el conflicto. Proponemos que este paso sea primero y prioritario para cualquier análisis de resolución de conflictos.

To what degree can language be acquired from linguistic input alone? This question has vexed scholars for millennia and is still a major focus of debate in the cognitive science of language. The complexity of human language has hampered progress because studies of language–especially those involving computational modeling–have only been able to deal with small fragments of our linguistic skills. We suggest that the most recent generation of Large Language Models (LLMs) might finally provide the computational tools to determine empirically (...) how much of the human language ability can be acquired from linguistic experience. LLMs are sophisticated deep learning architectures trained on vast amounts of natural language data, enabling them to perform an impressive range of linguistic tasks. We argue that, despite their clear semantic and pragmatic limitations, LLMs have already demonstrated that human-like grammatical language can be acquired without the need for a built-in grammar. Thus, while there is still much to learn about how humans acquire and use language, LLMs provide full-fledged computational models for cognitive scientists to empirically evaluate just how far statistical learning might take us in explaining the full complexity of human language.

A partir de una presentación general del concepto de especie aplicado a los humanos, este texto expone dos nociones generales sobre la naturaleza humana: la tipológica y la filogenética. Una vez expuestos los fundamentos de cada noción, se defiende una distinción entre naturaleza humana e identidad humana como dos aspectos que se han confundido respecto a este problema, pero que cumplen distintos roles en las explicaciones, por lo que se proponen como dos nociones complementarias. Así, la naturaleza humana estaría definida (...) en términos metafísicos y daría cuenta de la realidad biológica de los humanos desde un punto de vista filogenético, mientras que la identidad humana estaría definida en términos epistemológicos y daría cuenta de los conocimientos que tienen los humanos sobre ellos mismos, aludiendo a aspectos contingentes.

Se realizó una revisión bibliográfica con el objetivo de sistematizar los principales postulados existentes respecto a la Historia Regional como disciplina y su relación con la asignatura Historia de Cuba. La información aportada se procesó según los métodos científicos de análisis y síntesis e histórico lógico. Ello incluyó la interpretación de los criterios vertidos por especialistas que permiten considerar a Camagüey como una región histórica, en estrecho vínculo con las condiciones en las que se imparte la Historia de Cuba en (...) la Universidad de Ciencias Médicas de Camagüey, en la que la escasez de bibliografía sobre este tópico en particular influye sobre el estudio de la asignatura. Ello recalca la necesidad de desarrollar investigaciones de este tipo, con el propósito de que dichos estudios puedan ser empleados como materiales de apoyo a la docencia. A literature review was made in order to systematize the existing main postulates regarding Regional History as a discipline and its relationship with the subject History of Cuba. The information provided was processed according to scientific methods of analysis. synthesis and historico-logical. This included the interpretation of the criteria stated by specialists that allow to consider Camag|ey as a historical region, in close liaison with the conditions in which the history of Cuba is taught at the University of Medical Sciences in Camaguey, where the lack of literature on this topic particularly influences on the study of the subject. This underscores the need to develop research of this type, so these studies can be used as support for teaching materials. (shrink)

La actividad científico-informativa constituye un componente esencial de la actividad científica. Las etapas y tareas que la integran persiguen como propósito fundamental garantizar a los investigadores la información pertinente para el desarrollo exitoso de su trabajo. De ahí la necesidad de evaluar con periodicidad su comportamiento en las bibliotecas médicas. A partir de ello, el objetivo del estudio fue sistematizar los aspectos teórico-metodológicos correspondientes a la evaluación de la actividad científico- informativa en bibliotecas médicas. Para su realización se realizó revisión (...) bibliográfica en la que se analizaron tanto documentos normativos que rigen su accionar en el sector de la salud cubano, como materiales emitidos por otras instancias nacionales e internacionales. The informative work constitutes an essential component of the scientific work. The stages and tasks that comprise it pursue as fundamental purpose to ensure relevant information in order that researchers achieve the successful development of their work. Hence the need to assess regularly their behavior in the medical libraries. Based on that, the objective of the study was to systematize the methodological aspects relating to the evaluation of the scientific-informative work at the medical libraries. In order to accomplish this a broad literature review was made which analyzed both normative documents governing its actions in the Cuban health sector, as materials issued by other national and international bodies.

The relevance of Martin Heidegger’s thinking to Paul Celan’s poetry is well known. Between Celan and Heidegger proposes that, while the relation between them is undeniable, it is also marked by irreducible discord. Pablo Oyarzun begins with a deconstruction of Celan’s Todtnauberg, written after the poet visited Heidegger in his Schwarzwald cabin. The poem stands as a milestone, not only in the complex relationship between the two men but also in the state of poetry and philosophy in late modernity, (...) in the aftermath of the Holocaust. Discussion then turns to The Meridian, Celan’s acceptance speech for the prestigious Büchner Prize for German language literature. Other issues are insistently addressed—place, art, language, pain, existence, and the Heideggerian notion of dialogue—as Oyarzun revisits several essential poems from Celan’s oeuvre. A rare translation of Oyarzun’s work into English, Between Celan and Heidegger affirms the uniqueness of Celan’s poetry in confrontation both with Heidegger’s discourse on Dichtung (a poetic saying centered in the idea of gathering) and with Western philosophical notions of art, technē, mimesis, poiesis, language, and thinking more broadly.

What kind of discourse is likely to build up constitutional norms? How do legal-philosophical insights get along with competing political claims? This book presents the main conclusions from the CITC (Congreso Internacional de Teoria Constitucional) in Cordoba, Argentina. While addressing the very foundations of Constitutional Law, leading scholars from Europe and America got together to debate legal and political issues which impinge upon institutional design and polity assessment, political representation and rights protection. Not to mention other vexing challenges such as (...) the proper latitude of judicial review, the threatening phenomena of untamed emergency powers and the current international dimension of supra-national state-building. Beyond governance and human rights discourse, the core content of this book is concentrated on shedding some light on which theoretical and/or political conditions could better stand and give shelter to civil obedience and constitutional patriotism.

La lectio divina es un ejercicio ascético y espiritual usado por la comunicad cristiana en las asambleas litúrgicas. Desde los Padres del Desierto su práctica nunca se ha extinguido como ejercicio espiritual. Ahora parece haber vuelto con fuerza como ejercicio de lectura de la Palabra de Dios. La primera parte del artículo recrea los datos históricos fundamentales, la segunda explica su validez para los cristianos y las comunidades de nuestro tiempo.

In this paper we investigate a semantics for first-order logic originally proposed by R. van Rooij to account for the idea that vague predicates are tolerant, that is, for the principle that if x is P, then y should be P whenever y is similar enough to x. The semantics, which makes use of indifference relations to model similarity, rests on the interaction of three notions of truth: the classical notion, and two dual notions simultaneously defined in terms of it, (...) which we call tolerant truth and strict truth. We characterize the space of consequence relations definable in terms of those and discuss the kind of solution this gives to the sorites paradox. We discuss some applications of the framework to the pragmatics and psycholinguistics of vague predicates, in particular regarding judgments about borderline cases. (shrink)

Jean Paul Sarte, Franz Kafka i Milan Kundera: tres mirades diferents sobre la realitat, tres percepcions del món que participen d'un mateix rerafons filosòfic, d'una mateixa sensibilitat: l'absurd. Tres obres que neixen, creixen i maduren sota l'eclipsi de Déu, en l'atmosfera de la buidor més penetrant i la negació radical del sentit. L'ésser és estantís, feble, pura representació, i la vida humana una comèdia tragicòmica que comença per casualitat i s'acaba també per pura casualitat. Però l'home ha de viure, i (...) si el món no té sentit, caldrà forjar-lo amb les pròpies mans, caldrà projectar una idea per la qual valgui la pena viure i morir (Kierkegaard). Tres iniciatives, tres expectatives, que es configuren sota l'escola de l'absurd i la mort de Déu (Nietzsche). Davant d'aquesta concepció del món marcada pel desencís i l'angoixa hi ha la metafísica de la plenitud de l'ésser (sant Tomàs d'Aquino), que descriu l'univers com un dinamisme perfectiu que té una direccionalitat pròpia, una causa primera i un fi darrer. La lògica del sentit versus la lògica de la buidor. (shrink)

En este trabajo vamos a estudiar el significado del termino "ser" y del termino "vida" en los textos de Santo Tomas de Aquino. Vamos a tratar de descifrar el contenido semantico de estos vocablos y poner de relieve la relacion significativa entre ambos. Que es el ser? Que es la vida? Que vinculo existe entre ser y vida? Que es primero desde el punto de vista ontologico? Que es mas perfecto? Estas son algunas de las cuestiones que planteamos en el (...) presente articulo. (shrink)

La història del pensament occidental travessa ara per ara un punt d'inflexió, un instant de vacil·lació, de dubte i de recerca. El fil conductor de la Modernitat s'ha exhaurit i l'esperit desencisat cerca noves formes de pensar i noves cosmovisions. Les idees rectores de la Modernitat han caigut de l'escambell i la corba del pensament travessa un moment delicat, un instant que cal meditar pausadament. Aquest moment inestable i fugisser és la postmodernitat. S'acosta una nova era de l'esperit, però encara (...) no ha pres forma. Manca creativitat, manquen idees, manca passió per la veritat. En aquest assaig recollim algunes idees de Kierkegaard que poden il·luminar el panorama gris i enrarit de la filosofia actual. (shrink)

Un atlas zoopolítico es lo que pretende tener aquí lugar. Un atlas en el sentido en que cada pequeño tratado de los cincuenta y dos que configuran el libro se presenta en la forma de un retrato donde el pensamiento, entre sus pensadores, se aplica en el esfuerzo de hacerse cargo de la presencia animal sin renunciar a la diferencia humana, y en que, entre todos ellos, se delinea en todas sus valoraciones posibles esta nueva presencia del animal entre nosotros. (...) Retrato con animal. Prefacio. Pablo Perera Velamazán es escritor, además de filósofo e historiador del arte. Esta triple condición –y alguna otra (profesor, traductor)- le han permitido entrar en el círculo de los que escriben siempre de los que no saben y le ha impedido, también formar parte de ninguna empresa concreta, salvo la del precipicio del pensamiento en la singularidad que se resiste a los nombres. Allí suelen estar acompañado de niños y animales, de ángeles como muñecos, pero allí también se pueden encontrar a cualquiera. Buen compañero de viaje de invierno. (shrink)

This is a collective work of philosophy of science on a topic, even though it could already be considered a classic, of great academic actuality in the field: change and incommensurability in science. The contributors are researchers from Spain, Argentina, Mexico, Brazil and Colombia.

This paper presents and defends a way to add a transparent truth predicate to classical logic, such that and A are everywhere intersubstitutable, where all T-biconditionals hold, and where truth can be made compositional. A key feature of our framework, called STTT (for Strict-Tolerant Transparent Truth), is that it supports a non-transitive relation of consequence. At the same time, it can be seen that the only failures of transitivity STTT allows for arise in paradoxical cases.
