We show a sentence and modal square of opposition and equivalence to be expanded into an hexagon according to oe suggestion from William of Sherwood. This expansión is permittedby two sentence and modal rules.The logical relations of the square allow us to formulate several theorems in order to show a glimpse of the Medieval Logic complexity.

In this article, after some thoughts on medieval logic and teaching, we present Thomas Murner’s text, Logica memorativa, showing some of his mnemonic strategies for the student to learn logic quickly. Murner offers a type of “flash cards” that illustrate much of the teaching of logic at the beginning of the sixteenth century. The first impression is visual, because the cards do not contain words that illustrate their content. Murner’s exposition rests on analogies between logic themes that are explained and (...) the visual images presented. (shrink)

I describe an octagon of opposition and equivalence developed by fourteenth-century logicians, in particular by Jean Buridan in his Summulae de dialectica. This «square» of opposition displays complex logical relations, one of which is not found in the traditional square of opposition. The octagon allows expression of three kinds of sentences: quantified modal sentences, oblique sentences, and sentences with quantified predicates. The octagon shows that medieval logicians were working with a logic of relations, an identity logic, and a modal logic (...) not unlike the logic of our own day. (shrink)

In this paper the medieval octagons of opposition and equivalence are described and analized. One of them, the octagon for quantified predicates, is the simplest one and offers the pattern for the other two, the octagon for predicate with modal qualification and the octagon for quantified genitive and nominative sentences. Thus, the first is the princeps analogum for the other two, whose structure is more complex. Then we describe an internal square inside the octagon, the square of the so-called disparatae (...) sentences, which obey no law from the traditional Aristotelian square. (shrink)

I present some ideas from medieval thinkers concerning sentences which subject term has no reference and as kif those sentences can admit truth values. I present the ideas of William of Ockham, Jean Buridan and Albert of Saxony, from the nominalist side, and Vicente Ferrer exposing the moderate realism. Then we present two New Spain thinkers, Alonso de la Veracruz and Tomas de Mercado.

The traditional Square of Opposition consists of four sentence types. Two are universal and two particular; two are affirmative and two negative. Examples, where ‘S’ and ‘P’ designate the subject and the predicate, are: ‘every S is P’, ‘no S is P’, ‘some S is P’ and ‘some S is not P’. Taking the usual sentences of the square of opposition, quantifying over their predicates exhibits non-standard sentence forms. These sentences may be combined into non-standard Squares of Opposition , and (...) they reveal a new relationship not found in the usual Square. Medieval logicians termed ‘disparatae’ pairs of sentences like ‘every S is some P’ and ‘some S is every P’, which are neither subaltern nor contrary, neither contradictory nor subcontrary. Walter Redmond has designed a special language L to express the logical form of these sentences in a precise way. I will use this language to show how Squares of Opposition, standard and non-standard, form a complex network of relations which bring to .. (shrink)

En el presente artículo describo un octágono de oposición y equivalencia desarrollado por lógicos del siglo XIV, especialmente por Jean Buridan en su Summulae de dialectica. Dicho �cuadro� de oposición ofrece relaciones lógicas muy complejas, alguna de las cuales no está presente en el cuadrado tradicional de oposición. El octágono nos servirá para expresar tres tipos de oraciones: oraciones modales cuantificadas, oraciones oblicuas y oraciones con cuantificación explícita del predicado. El octágono muestra que la lógica medieval del siglo XIV ofrece (...) ya una lógica de relaciones, una lógica de la identidad y una lógica modal comparable a la lógica de nuestros días. (shrink)

Benito Jerónimo Feijoo (1676-1764) fue uno de los autores que, a partir del siglo XVI, formularon críticas a la enseñanza de la lógica clásica. En el presente artículo se examinan varios de los argumentos esgrimidos por Feijoo contra la lógica tradicional; algunos de estos se explican mejor al revisar la obra del pensador Novohispano Tomás de Mercado (15?-1575). Se resaltan los planteamientos de Feijoo que son afines o pertinentes a las críticas actuales a la lógica.

El presente artículo expone, de manera general, ciertos aspectos de la clasificación de oraciones realizada por varios autores en la edad media y más tarde en el autor novohispano Tomás de Mercado.

Presentamos la doctrina tradicional de la conversión simple de las oraciones categóricas y de las oraciones modales cuantificadas atendiendo al análisis medieval de las mismas en base a las oraciones de identidad. Estas oraciones de identidad resultan ser necesarias cuando son verdaderas e imposibles cuando son falsas. Simplificamos nuestro tratamiento reduciendo nuestro universo del discurso a pequeños �mundos� de individuos y propiedades recurriendo en parte al simbolismo ordinario y añadiendo un símbolo para la parte modal.

Presentamos algunas ideas acerca de la relación entre libertad y contingencia atendiendo a sus componentes modales. Nuestra idea central es que la libertad es posible gracias a la contingencia, pero este hecho no es gratuito. En efecto, trataremos de mostrar que si bien la contingencia es básica para la libertad, esto mismo no es contingente. Pues si la contingencia misma no fuera necesaria, no podría fundamentar la libertad. Así que la contingencia misma puede recibir calificaciones modales.

Presentamos algunas ideas de autores medievales acerca de las oraciones cuyo sujeto carece de referente, y si dichas oraciones. Los autores tratados son nominalistas del siglo xiv: Guillermo de Ockham, Alberto de Sajonia y Juan Buridan; y el realista moderado Vicente Ferrer. Luego abordamos a dos novohispanos, Alonso de la Veracruz y Tomás de Mercado, que están inmersos en la tradición medieval.

We propose a new interpretation of the equation E=mc² in special relativity by generalizing ideas of ontological emergence to fundamental physics. This allows us to propose that mass, as a property, can be considered to emerge from energy, using a well-known definition of weak ontological emergence. Einstein’s famous equation gains in this way a clearer philosophical interpretation, one that avoids the problems of previous attempts, and is fully consistent with the kinematic properties of special relativity, while yielding fresh insights concerning (...) the nature of mass.

May I be permitted to chat a little, by way of recreation, at the end of a somewhat toilsome and perhaps fruitless adventure?”1 So begins the introduction to Robert Browning’s “transcription,” as he entitles it, of Aeschylus’s Agamemnon, in which the principles of literal translation are discussed and defended.2 As one who has recently been on the same adventure as Robert Browning, I wonder whether it is not salutary to review his arguments, for I have come to believe firmly that (...) the path he took was fruitless, or very nearly so. Yet of the many translators, stretching into the most recent times, who have provided us with literal renditions of ancient Greek texts, he at least offered an apology for it, and a better one, in my view, than any I have seen. I want to try, by reviewing Browning’s arguments, to shed some light on why his adventure of translation was barren, and in the process state some precautions for the translation of ancient Greek literature. I am not sure whether these precautions apply to the philosophy of translation in general, for the differences between two languages vary greatly with time and place; nevertheless, the review may be of some general help.

Processing data streams arriving at high speed requires the development of models that can provide fast and accurate predictions. Although deep neural networks are the state-of-the-art for many machine learning tasks, their performance in real-time data streaming scenarios is a research area that has not yet been fully addressed. Nevertheless, much effort has been put into the adaption of complex deep learning (DL) models to streaming tasks by reducing the processing time. The design of the asynchronous dual-pipeline DL framework allows (...) making predictions of incoming instances and updating the model simultaneously, using two separate layers. The aim of this work is to assess the performance of different types of DL architectures for data streaming classification using this framework. We evaluate models such as multi-layer perceptrons, recurrent, convolutional and temporal convolutional neural networks over several time series datasets that are simulated as streams at different speeds. In addition, we evaluate how the different architectures react to concept drifts typically found in evolving data streams. The obtained results indicate that convolutional architectures achieve a higher performance in terms of accuracy and efficiency, but are also the most sensitive to concept drifts. (shrink)

Este trabajo explora las representaciones de las mujeres en una selección de manuales escolares empleados en las escuelas paraguayas durante el período 1989-2020, con el objetivo de analizar el papel histórico atribuido a las mujeres en los relatos escolares acerca de la Guerra de la Triple Alianza. Se sostiene que a pesar del proceso de revisión del currículo escolar y la política educativa iniciado con la transición democrática en 1989 persisten las representaciones hegemónicas de las mujeres ligadas al nacionalismo, afianzando (...) los roles tradicionales de género en el marco de una sociedad patriarcal.

El presente artículo pretende aportar información concisa y útil acerca de un género cinematográfico sumamente apreciado por la crítica: el cine no narrativo. Para ello, en una primera parte se resaltan los fundamentos teóricos, sobre todo antropológicos, que dan a las películas no narrativas su carácter central, tanto estructural como elocutivo, como reflejo de un arte que reproduce el origen de los mitos; en una segunda parte se ofrecen ejemplos concretos de su funcionamiento con base en esos fundamentos y se (...) infieren los modos en que esas películas son recibidas por la audiencia; finalmente, se concluye cuál ha sido la influencia e importancia de este tipo de cine a lo largo de la historia y se explora el posible futuro de este tipo de cine. El método empleado es inductivo y cualitativo, por lo que la interpretación personal tiene primacía en este trabajo. (shrink)

La igualdad entre hombres y mujeres no será plena mientras que no transformemos el orden patriarcal que sigue sustentando una diferenciación jerárquica entre unos y otras. Ello pasa por revisar la masculinidad tradicional y la racionalidad construida a imagen y semejanza del varón. Un reto que supone a su vez transformar las relaciones entre lo público y lo privado, así como las bases del conocimiento y de una concepción de lo humano basada en los privilegios masculinos y en la negación (...) de la diversidad.Equality will not be full if we don’t transform the patriarchal order that continues to support a hierarchical differentiation between men and women. This calls for reviewing the traditional masculinity and the rationality constructed in the image and the likeness of the male. A challenge which in turn means to transform the relationship between public and private, and the basis of knowledge and a conception of humanity based on male privilege and the denial of diversity.

En este artículo se realiza una semblanza general del pensador colombiano Darío Botero Uribe, en especial, sobre sus ideas en torno al pensamiento latinoamericano. En este sentido, se aborda el problema de la particularidad y la universalidad del pensamiento, la crítica de la modernización y el colonialismo intelectual, el problema de la cultura y de su puesto en la filosofía latinoamericana y colombiana, a la vez que establece una relación con la problemática del mestizaje indoamericano.

This article presents evidence over which we stumbled while investigating a completely different part of the Platonic Corpus. While examining the ordinary working vocabulary of the doubtful dialogues and of those undisputed dialogues most readily compared with them, it seemed essential to have a representative sample of Plato's allegedly 'middle' and 'late' dialogues also. The real surprise came when the Critias was included, showing some frequencies not previously observed in Platonic dialogues. This prompted treatment of the Timaeus also, some of (...) which showed comparable peculiarities. The most distinctive feature was the increase in the rate of the definite article from around 8% of total vocabulary in dialogues assumed to be early, or around 10% in Laws, to some 14% in sizeable parts of the Timaeus-Critias, where Plato seemed no less interested in the literary credentials of his creations than elsewhere. Tests intended for application to our original set of problems were yielding results that appeared to bear on a number of problems central to the interpretation of the Timaeus-Critias. (shrink)

Francisco Suárez se inserta en la línea de los escolásticos españoles del siglo XVI, especialmente de los dos jesuitas que, junto con él, culminan esta escuela: Gabriel Vázquez de Belmonte y Luis de Molina. Se diferencia de ellos en que él es nominalista. Se adelantó a los autores de la Edad Moderna en la carrera por las libertades típicamente modernas, tales como la afirmación de los derechos subjetivos naturales, la democracia como la forma más natural o más próxima a la (...) libertad del hombre, la libertad de conciencia (no de cultos). Estuvo omnipresente en los escolásticos de las Edades Modernas y Contemporánea que, de hecho, entendieron que él culminó la escolástica, de forma tal que también Tomás de Aquino debe ser interpretado a la luz de sus escritos.

One of the most important contributions of Einstein to the philosophy of science is the distinction between two types of scientific theories: ‘principle’ and ‘constructive’ theories. More recently, Flores proposed a more general distinction, classifying scientific theories by their functional role into ‘framework’ and ‘interaction’ theories, attempting to solve some inadequacies in Einstein’s proposal. Here, based on an epistemic criterion, we present a generalised distinction which is an improvement over Flores approach. In this work (i) we evaluate the shortcomings related (...) to Flores’s proposal, (ii) we present an epistemological criterion that opens the door for a more general classification of any scientific theory in all of the natural science into two distinct groups, which we call ‘mechanistic theories’ and ‘structural theories’, and (iii) we show that such a criterion is connected to Flores’ proposal while overcoming issues of all previous approaches.

A common approach for measuring the effectiveness of an education system or a school is the estimation of the impact that school interventions have on students’ academic performance. However, the latest trends aim to extend the focus beyond students’ acquisition of knowledge and skills, and to consider aspects such as well-being in the academic context. For this reason, the 2015 edition of the international assessment system PISA incorporated a new tool aimed at evaluating the socio-affective variables related to the well-being (...) of students. It is based on a definition focused on the five dimensions proposed in PISA theoretical framework: cognitive, psychological, social, physical and material. The main purpose of this study is to identify the well-being components that significantly affect student academic performance and to estimate the magnitude of school effects on the well-being of students in OECD countries, the school effect being understood as the ability of schools to increase subjective student well-being. To achieve this goal, we analyzed the responses of 234,000 students from thirty-five OECD countries to PISA 2015 questionnaires. Specifically, we considered non-cognitive variables in the questionnaires and student performance in science. The results indicated that the cognitive well-being dimension, composed of enjoyment of science, self-efficacy and instrumental motivation, as well as the test anxiety all had a consistent relationship with student performance across countries. In addition, the school effect, estimated through a two-level hierarchical linear model, in terms of student well-being was systematically low. While the school effect accounted for approximately 25% of the variance in the results for the cognitive dimension, only 5-9% of variance in well-being indicators was attributable to it. This suggests that the influence of school on student welfare is weak, and the effect is similar across countries. The present study contributes to the general discussion currently underway about the definition of well-being and the connection between well-being and achievement. The results highlighted two complementary concerns: there is a clear need to promote socio-emotional education in schools, and it is important to develop a rigorous framework for well-being assessment. The implications of the results and proposals for future studies are discussed. (shrink)

This is a critical review of Manuel García-Carpintero's "Las palabras, las ideas y las cosas".

This work deals with obstacles hindering a metaphysics of laws of nature in terms of dispositions, i.e., of fundamental properties that are causal powers. A recent analysis of the principle of least action has put into question the viability of dispositionalism in the case of classical mechanics, generally seen as the physical theory most easily amenable to a dispositional ontology. Here, a proper consideration of the framework role played by the least action principle within the classical image of the world (...) allows us to build a consistent metaphysics of dispositions as charges of interactions. In doing so we develop a general approach that opens the way towards an ontology of dispositions for fundamental physics also beyond classical mechanics. (shrink)

We argue that the distinction between framework and interaction theories should be taken carefully into consideration when dealing with the philosophical implications of fundamental theories in physics. In particular, conclusions concerning the nature of reality can only be consistently derived from assessing the ontological and epistemic purport of both types of theories. We put forward an epistemic form of realism regarding framework theories, such as Quantum Field Theory. The latter, indeed, informs us about the general properties of quantum fields, laying (...) the groundwork for interaction theories. Yet, concerning interaction theories, we recommend a robust form of ontological realism regarding the entities whose existence is assumed by these theories. As an application, we refer to the case of the Standard Model, so long as it has proved to successfully inform us about the nature of various sorts of fundamental particles making up reality. In short, although we acknowledge that both framework and interaction theories partake in shaping our science-based view of reality, and that neither would do by itself the work we expect them to accomplish together, our proposal for a coherent ontology of fundamental entities advances a compromise between two forms of realism about theories in each case.
