The present text book is intended as an introduction to elementary logic. Its content, structure, and manner have been determined in large measure - perhaps 'caused' is the better word- by certain desiderata about which the reader should be informed at the outset. The leading idea is that even an introductory treatment of logic may profitably be fashioned around a rigorous framework.

This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1973.

The meanings of utterances and thoughts are commonly regarded in philosophical semantics as abstract objects, called «propositions», which account for how different utterances and thoughts can be synonymous and which constitute the primary truth-bearers. I argue that meanings are instead natural properties that play causal roles in the world, that the kind of «One over Many» thinking underlying the characterization of shared meanings as abstract objects is misguided and that utterances and thoughts having truth-values in virtue of their meanings does (...) not entail that meanings themselves are truth-bearers.

A large part of technological advances, especially in the field of industry, have been focused on the optimization of productive processes. However, the detection of anomalies has turned out to be a great challenge in fields like industry, medicine or stock markets. The present work addresses anomaly detection on a control level plant. We propose the application of different intelligent techniques, which allow to obtain one-class classifiers using real data taken from the correct plant operation. The performance of each classifier (...) is assessed and validated with real created faults, achieving successful overall results. (shrink)

Based on an ethnographic case study, we describe the family experiences and the access to formal education of 30 Paraguayan women to show how these factors influence their labor insertion at the Paraná Tri-Border Area. We will start by reviewing the theoretical debates about gender inequality in labor insertion in border territories. Then, we will explain the study’s methodology and the profile of the interviewees. The analysis consists in describing the relationship between the rural origins of these women and gender (...) inequalities; we will establish how these inequalities are related to low access to formal education and the precariousness of their insertion into the job market. In addition, we will show how these circumstances imply a contradiction in their work experience on the border, between the abuses suffered and the autonomy gained; and we will analyze the expectations of transgenerational transformation that our protagonists project in their children.

Nowadays, the quality standards of higher education institutions pay special attention to the performance and evaluation of the students. Then, having a complete academic record of each student, such as number of attempts, average grade and so on, plays a key role. In this context, the existence of missing data, which can happen for different reasons, leads to affect adversely interesting future analysis. Therefore, the use of imputation techniques is presented as a helpful tool to estimate the value of missing (...) data. This work deals with the academic records of engineering students, in which imputation techniques are applied. More specifically, it is assessed and compared to the performance of the multivariate imputation by chained equations methodology, the adaptive assignation algorithm based on multivariate adaptive regression splines and a hybridization based on self-organisation maps with Mahalanobis distances and AAA algorithm. The results show that proposed methods obtain successfully results regardless the number of missing values, in general terms. (shrink)

In this paper I aim to think about a set of different issues in relation to Marx’s philosophy on the light of the experience of Paris Commune. More specifically, I would like to point out that Marx’s experience facing the Commune could be constituted as a revealing indicator of some of the most significant outlines of his philosophy. Firstly, I am proposing an analysis of the letter from Marx to Ruge in Kreuznach with the purpose of thinking over young Marx’s (...) revolution idea by identifying two critical aspects that modify and project it transformed towards the Commune. In second place, I present a re-reading of The Civil War in France crossed by an internal disjunction between the scientific, political and philosophical words that are present in Marx, but that resist to be reappropriated in a single speech.

The use of batteries became essential in our daily life in electronic devices, electric vehicles and energy storage systems in general terms. As they play a key role in many devices, their design and implementation must follow a thorough test process to check their features at different operating points. In this circumstance, the appearance of any kind of deviation from the expected operation must be detected. This research deals with real data registered during the testing phase of a lithium iron (...) phosphate—LiFePO4—battery. The process is divided into four different working points, alternating charging, discharging and resting periods. This work proposes a hybrid classifier, based on one-class techniques, whose aim is to detect anomalous situations during the battery test. The faults are created by modifying the measured cell temperature a slight ratio from their real value. A detailed analysis of each technique performance is presented. The average performance of the chosen classifier presents successful results. (shrink)

El presente trabajo aborda lo que Hegel denomina ‘método de ejecución’ en la Introducción de la Fenomenología del Espíritu. Lo que me propongo es dar una explicación acerca de cómo opera este método tal que logre cumplir las metas que Hegel mismo se propone. En particular, pretendo explicar por qué el objeto para cada figura de la conciencia es cada vez uno distinto y por qué el nuevo objeto surge a partir de la corrección del saber que se encarna en (...) una cierta figura de la conciencia. Me centro en criticar las respuestas a estas preguntas que extraigo de varios autores, con especial atención en cuatro de ellos: Kenneth Westphal (1998), Robert Brandom (2019), Stephen Houlgate (2013) y Robert Pippin (1989). Luego, propongo un bosquejo de mi propia explicación, la cual recurre al uso de un criterio interno de la verdad análogo al que Spinoza emplea para su filosofía. (shrink)

En este trabajo se pretende mostrar el sentido político que adquirió la defensa de la teoría por parte de Adorno en los últimos años de su vida. él empleó esta defensa como una respuesta a los imperativos de los estudiantes de izquierda de plegar la teoría crítica a la intervención práctica inmediata. Para justificar esta tesis se atiende no sólo a lo que decía, sino también, en un nivel discursivo diferente, a lo que estaba haciendo cuando empleaba concentraciones de términos (...) y enunciados densos y eruditos para manifestarse. Esto lleva a incluir las reflexiones y valoraciones de Adorno referentes a la actitud teorética y a la praxis, principalmente aquellas esbozadas en Dialéctica negativa, en un contexto más amplio. This work pretends to show the political sense that the defense of the theory by Adorno acquired in the last years of his life. He used this defense as an answer to the students's imperatives of applying the critical theory to the immediate practical intervention. In order to justify this thesis will be considered not only what Adorno said, but also, in a different discursive level, what he was doing on having used concentrations of terms and dense and erudite declarations. This entails, then, to relate Adorno's reflections and assessments concerning to the theoretical and practical approach -specially those outlined in Negative Dialectic- to a broader contextual framework.

An argument proposed by Steglich-Petersen (2012) establishes that while contrastive causation can be applied to general causation and causal explanation, it is a mistake to consider it in cases of singular causation. I attempt to show that there is no mistake. Steglich-Petersen’s argument does not seem to be strong enough and is actually circular. Furthermore, I briefly argue that even if we take his argument to be valid, there is still a response from the side of contrastive causation.

This article addresses the question raised by the Anthropocene of rethinking the concept of autonomy which, in the conditions of the new geological epoch, is subject to a crisis of legitimation. It explores the ‘strong hypothesis’ according to which nature is a necessary condition of our qualitative experience of the world and a constitutive relation of autonomy defined as the self-realisation of individual identity. With this aim in mind, the article attempts to rethink the concept of recognition in order to (...) conceive a recognising attitude of nature in the form of love of nature as a form of adequate recognition. Rethinking recognition can serve as foundation of an ‘objective’ theory of autonomy, that is, a theory that explains how nature can be defined as a condition and constitutive relation of autonomy. The article, therefore, proposes to reformulate the concept of autonomy as the self-realisation of an ecological or environmental identity in the form of the self-realisation of an ecological ethos, that is, an attitude of respect and care for nature. This enquiry, ultimately, is a contribution to the task of rethinking the basis of our conceptions of autonomy and freedom in the Anthropocene, so that the idea of autonomy can legitimately constitute the central value of the social transformation that is needed to face the ecological crisis.

El presente artículo se inscribe en el ámbito de la teoría política contemporánea pretendiendo indicar a Louis Althusser como un autor clave para la interrogación sobre la política en la actualidad. Se propone una revisión de la lectura althusseriana de Maquiavelo que permita esbozar dos puntos a desarrollar de manera preliminar. En primer lugar, responder a la pregunta sobre el por qué de la recurrencia al fiorentino por parte del filósofo comunista. Se sostendrá que la lectura de Maquiavelo sobredetermina la (...) intervención teórica de Althusser incorporando ‘nuevos’ temas y reactualizando ‘viejos’ interrogantes del althusserianismo. De modo que una lectura como esta permitiría recuperar de una manera específica cierto legado del autor. En segundo lugar, por medio del tratamiento de la problemática del comienzo en política en sus condiciones de imposibilidad -entre la eterna repetición de lo mismo y la absoluta contingencia por venir-, se señalará que lo que el autor encuentra frente a Maquiavelo es la posibilidad de una expansión del potencial de sentido de la política frente a quienes pretenden reducirla en su concepto y sus efectos. Producto de este análisis se señalará hasta qué punto la interrogación de Althusser por la política puede ser inscripta en un horizonte teórico posfundacional. (shrink)

En este artículo propongo una lectura de los primeros capítulos de Montesquieu. La politique et l’histoire de Louis Althusser con el fin de señalar el modo en el que las primeras menciones a Spinoza en la obra de Althusser se producen junto a Montesquieu y reflexionar sobre el sentido crítico de esas menciones. Con un estudio como este quisiera, primero y en general, señalar la importancia no siempre del todo reconocida que tuvo Montesquieu en el desarrollo teórico de Althusser. Segundo, (...) analizar el significado de las alusiones críticas a Spinoza presente en este escrito. Y, tercero, indicar los trazos que configurarían las condiciones de posibilidad de la integración del spinozismo al pensamiento de Althusser. (shrink)

Este artículo explora el cruce de la historia cultural y los estudios sonoros que propone el libro Escuchar Malvinas. Músicas y sonidos de la guerra, compilado por el autor junto con Abel Gilbert en 2022. Desarrolla tres ideas, presentes en ese libro y en otros textos del autor (como el libreto para la ópera Aliados de Sebastian Rivas): i) la guerra de Malvinas como una forma de radioteatro, a partir de los comunicados de la Junta Militar y el Estado Mayor (...) Conjunto; ii) el aporte del concepto de “cultura de guerra” para entender el apoyo popular a la recuperación de las islas por la dictadura; iii) la guerra como culminación de la “épica de Estado” inscripta desde 1813 en el himno nacional, cuya antípoda es la figura del desertor, presente en la narrativa argentina desde 1982.

En partant de la notion de « jargon » mobilisée par Adorno dans son livre contre Heidegger, cet article entend contribuer à une histoire sociale du concept d’authenticité, dans une perspective critique qui s’intéresse à ses usages au sein de différents milieux musicaux et musicologiques. Le rock et la pop, les musiques ethniques et/ou traditionnelles, les musiques anciennes, sont autant de contextes où dans la deuxième moitié du vingtième siècle ont pris forme de manière indépendante ce qu’on peut appeler des (...) querelles de l’authenticité. Nous faisons l’hypothèse que cela s’explique moins pour des raisons techniques communes à ces différents types de musiciens que parce que la diffusion de l’existentialisme et la vogue de la contreculture dans les années 1960 ont installé dans le sens commun l’idée qu’une vie authentique est l’un des noms contemporains de la vie bonne.

Think of the sublime: images come to mind first. Images of mountains, oceans, deserts, and other wild natural sites. Images of pyramids, cathedrals, skyscrapers, and other colossal cultural artifacts. Most of these mental images are probably still and silent, very much like photos. They might also portray dynamic situations, like big waves breaking on a rocky shore, or high trees moved by a thunderous storm, or the wind howling across the ruins of an ancient temple. Yet these scenes are likely (...) to be imagined as sublime independently of their inner temporality, perhaps as animated still pictures like GIFs or “live” smartphone photos.But maybe something else comes to your mind. If you are a classical music lover, you... (shrink)

Este artículo tematiza la relevancia del Hamlet, de Shakespeare, para el pensamiento de T. W. Adorno, aun cuando este no haya escrito in extenso sobre aquel. El drama aparece sobre todo en su discurso oral como modelo para describir la relación de discontinuidad entre teoría y práctica. Aquí se desea mostrar cómo el teórico crítico del pensamiento moral abstracto piensa el paso del conocimiento a la praxis a partir del vínculo entre Hamlet y el llamado “factor añadido” (Das Hinzutretende). Desde (...) esta lectura, el Hamlet de Adorno representa un lugar clave de transiciones malogradas. (shrink)

The thirty year long friendship between Imre Lakatos and the classic scholar and historian of mathematics Árpád Szabó had a considerable influence on the ideas, scholarly career and personal life of both scholars. After recalling some relevant facts from their lives, this paper will investigate Szabó's works about the history of pre-Euclidean mathematics and its philosophy. We can find many similarities with Lakatos' philosophy of mathematics and science, both in the self-interpretation of early axiomatic Greek mathematics as Szabó reconstructs it, (...) and in the general overview Szabó provides us about the turn from the intuitive methods of Greek mathematicians to the strict axiomatic method of Euclid's Elements. As a conclusion, I will argue that the correct explanation of these similarities is that in their main works they developed ideas they had in common from the period of intimate intellectual contact in Hungarian academic life in the mid-twentieth century. In closing, I will recall some relevant features of this background that deserve further research. (shrink)

We focus on the question of how expertise as conceived by the Stoics interacts with the content of impressions. In Section 1, we situate the evidence concerning expert perception within the Stoic account of cognitive development. In Section 2, we argue that the content of rational impressions, and notably of expert impressions, is not exhausted by the relevant propositions. In Section 3, we argue that expert impressions are a subtype of kataleptic impressions which achieve their level of clarity and distinctness (...) due to the contribution of expertise. In Section 4, we argue that the expertise in living well not only allows the wise person to assent correctly but also affects the content of her impressions. We suggest that these two models – one’s attitude toward an impression being informed by expertise, and one’s impressions being affected by expertise – might characterize distinct stages of cognitive development. Stoic wisdom is not only a matter of the way one assents to one’s impressions but also a matter of the condition of one’s soul and, consequently, of the kinds of impressions one even entertains. Expertise offers a model of how cognitive and discriminatory improvement through practice and effort can transform the non-wise into the wise. A reading on which the content of impressions is not exclusively propositional illuminates a further aspect of this transformation. If the same propositions are accessible through impressions with different non-propositional content, we can account for cases in which the novice and the expert entertain the same proposition.

En este trabajo abordamos la relación entre escepticismo, materialismo y clandestinidad en los primeros escritos de Denis Diderot. A partir del estudio de las referencias al escepticismo encontradas en su traducción de An Inquiry Concerning Virtue or Merit de Shaftesbury y analizando las posiciones sostenidas posteriormente en dos obras de su propia autoría -Pensamientos filosóficos y El paseo del escéptico -, intentamos mostrar: a) qué significado tiene el escepticismo en tanto actitud filosófica en la obra del joven Diderot, y b) (...) cómo se configuró la transformación de mitad de siglo en el movimiento ilustrado y qué papel cumplió nuestro autor en la misma. In this paper, we study the connections between skepticism, materialism and clandestinity in Denis Diderot' first writings. Leaning on the references found in his translation of Shaftesbury's An Inquiry Concerning Virtue or Merit in the first place and, secondly, analyzing what Diderot says as an author in two of his works -Philosophical Thoughts and The Skeptic's Walk - we try to show: a) what's the meaning of skepticism as a philosophical attitude in young Diderot's writings; b) how transformation at the Enlightenment movement in the second half of the Eighteenth Century was configured, and what was Diderot's role in that transformation.

Este artículo analiza relatos biográficos críticos acerca de las experiencias con profesionales y terapias del ámbito de la salud mental por problemas relacionados con depresiones. En un contexto de expansión y diversificación de los discursos y prácticas del campo psi, indaga en las perspectivas y cuestionamientos de usuarios/as de servicios psicoterapéuticos. La pregunta principal que lo orienta es: ¿En las narrativas biográficas cuáles son las críticas que realizan a las prácticas terapéuticas y a quienes la ejercen? Un segundo interrogante: ¿Es (...) posible localizar alguna relación de afinidad entre tipos particulares de críticas y de estilo de terapia psi? Estas cuestiones son abordadas a partir de una investigación empírica, realizada en la ciudad de Santa Fe, Argentina. Se analizan 42 entrevistas biográficas para indagar en el repertorio de objeciones que efectúan a las terapéuticas psi personas involucradas en procesos psicoterapéuticos. El artículo localiza un conjunto de relatos que cuestionan la falta de empatía; la falta de provisión de herramientas; la falta de credibilidad; la jerarquía en la relación; y, finalmente, la ilusión de recuperación. Cada uno de estos tipos de críticas suelen adquirir mayor presencia en determinadas prácticas terapéuticas. En estos estilos de objeciones se hallan críticas más singularizadas —orientadas a personas particulares que ejercen de terapeutas— y más generalizadas —dirigidas a los fundamentos de las terapias. El trabajo contribuye a los estudios sociales sobre el campo psi al producir conocimiento empírico acerca de los saberes críticos por experiencia de personas involucradas en diferentes terapias psi.

In this paper we intend to present some medieval foundations, especially Franciscan, of the revitalized civic republicanism of the 20th century. There is an unjustified leap from Rome to the Renaissance that has its origin in the forgetfulness and simplistic view that Hanna Arendt has of medieval thought and Aristotelianism, caused by the historiographic criteria of her time. For this we will show some characteristics of the thought of this new republicanism in order to present the central ideas of four (...) Franciscan authors: Francesc Eiximenis, Bonaventure, Duns Scotus and Alfonso de Castro. First we will try to show the continuity that exists between the Middle Ages and the Modern Age. With this historical approach we intend to analyze that the legitimate aspiration of this new republicanism is distorted and limited if it leaves aside medieval contributions that help to understand more fully the republican pretension the republican pretension that, without rejecting the autonomy of the individual or the sense of community, highlights the interactive nature of social life and instigates him to persevere in the pursuit of the common good.

Este artículo, desde posiciones teóricas diversas y a partir de anclajes históricos relevantes, advierte de la necesidad de no bajar la guardia ante comportamientos que promueven la violencia y amenazan la libertad, porque las imposiciones totalitarias siempre han ido precedidas de relatos salvíficos y apelaciones altruistas.
