How might artificial neural networks (ANNs) inform cognitive science? Often cognitive scientists use ANNs but do not examine their internal structures. In this paper, we use ANNs to explore how cognition might represent musical properties. We train ANNs to classify musical chords, and we interpret network structure to determine what representations ANNs discover and use. We find connection weights between input units and hidden units can be described using Fourier phase spaces, a representation studied in musical set theory. We find (...) the total signal coming through these weighted connection weights is a measure of the similarity between two Fourier structures: the structure of the hidden unit's weights and the structure of the stimulus. This is surprising because neither of these Fourier structures is computed by the hidden unit. We then show how output units use such similarity measures to classify chords. However, we also find different types of units—units that use different activation functions—use this similarity measure very differently. This result, combined with other findings, indicates that while our networks are related to the Fourier analysis of musical sets, they do not perform Fourier analyses of the kind usually described in musical set theory. Our results show Fourier representations of music are not limited to musical set theory. Our results also suggest how cognitive psychologists might explore Fourier representations in musical cognition. Critically, such theoretical and empirical implications require researchers to understand how network structure converts stimuli into responses. (shrink)

En los escenarios universitarios cada vez resulta menos extraño toparse con investigaciones que indagan por la escritura filosófica proveniente de centros no hegemónicos de producción de conocimiento. Nosotros, que hemos tenido la oportunidad de acercarnos al pasado del ejercicio de la filosofía en el actual territorio colombiano, quisimos hacer una convocatoria pública de escritos dedicados a identificar temas, preguntas y formas en que la variopinta comunidad de la filosofía local está escribiendo su propia historia.

This article is part of the period of methodological expansion, proposed by the philosopher Arturo Roig (1922-2012), in the 70's and 80's. Although the analysis of categories is rooted in the philosophical field, this expansion is made in the direction of social categories. More specifically to the categories of “civilization” and “barbarism”, both in the field of the history of ideas and in the philosophical history of Latin American liberation. First, we give different definitions and their multiple uses of (...) category in philosophy. Subsequently, we analyze the category of “human dignity”, one of the arms of the very broad anthropological a priori category, systematized by the thinker from Mendoza. Then we disaggregate the proposal of a categorical rearmament, which has among its multiple functions: the rescue, criticism, replacement, reworking and integration of categories that have been forgotten, distorted, dehistoricized and decontextualized. The categories of “civilization” and “barbarism” have generated a semantic ordering of the discursive universe in Latin America. We review different theses proposed by Roig, in the historicization of the assessment -both negative and positive- of the category “barbarism” that different thinkers in Latin America have expressed. Among them: Juan Montalvo, Domingo Faustino Sarmiento, José Hernández, Juan Bautista Alberdi, Ezequiel Martínez Estrada, among the main ones. (shrink)

La lectura del libro de Arturo Klenner La reconquista del amor al mundo. Hannah Arendt y el límite de la modernidad, publicado por esta casa de estudios, me sorprendió gratamente.

Este artículo propone una exploración de los textos compilados en Marginales de la Vida (1963), título publicado por el salvadoreño Arturo Ambrogi en 1912, a partir de los vínculos que se establecen en ellos entre la influencia de la estética modernista y el oficio periodístico practicado por el autor. Los objetivos centrales son aproximarse a la producción literaria de Arturo Ambrogi mediante un análisis de las tensiones generadas al momento de ubicar parte de su escritura dentro de la (...) literatura salvadoreña, centroamericana y latinoamericana de principios del siglo XX, a la vez que se postula la posible existencia de un híbrido literario que rehuyó en gran medida de los puntos de vista seguidos por otros autores contemporáneos de la región durante la época en estudio.

Resumen Aunque Carlos Arturo Truque sigue siendo poco conocido, no podemos hablar de literatura afrocolombiana, ni colombiana, sin su aporte. Con una producción literaria dispersa en publicaciones periódicas, el chocoano apuesta por el cuento cuando este no era suficientemente valorado en su país. Vivan los compañeros recoge todos sus cuentos, en los que se acerca tanto a los personajes excluidos de la sociedad como a los episodios de la historia colombiana más “vergonzosos”, desde un lenguaje que se aleja de (...) todo academicismo. Su obra, calificada en la época de “literatura sucia”, y ubicada concretamente en el Chocó y el puerto de Buenaventura, no es ajena a cualquier injusticia humana. Además, la necesidad de Truque de plasmar el habla de su comunidad no le impide contemplar las nuevas técnicas narrativas que llegaban entonces de Norteamérica. Así, renueva el cuento colombiano desde el plano formal y de contenido.Although Carlos Arturo Truque is still not well known, we cannot talk about Afro-Colombian, or Colombian literature, without mentioning his contribution. With an unfocused literary production in periodic publications, the “chocoano” bets on the short story when this genre was not highly valued in his country. Vivan los compañeros collects all his short stories, where he approaches the excluded characters of society as well as the more “shameful” episodes of Colombian history, from a language that distances itself from all academic art. His work, described at the time as “dirty literature” and specifically located in Chocó and the port of Buenaventura, is not alien to any human injustice. Besides, the need for Truque to express the speech of his community does not prevent him from contemplating new narrative techniques coming from North America. Thus, he renews the Colombian short story from the formal level and its content. (shrink)

El propósito del presente artículo radica en examinar el cruce de influencias entre la teoría ontológica y la praxis política. Más específicamente, nos interesa analizar de qué manera el estatus otorgado al khorismós platónico, es decir, al límite irrebesable entre el ámbito de los archaí y la dimensión de lo fenoménico, ha determinado el quehacer político europeo. La tesis que nos proponemos defender se formularía, pues, de la siguiente forma: las distintas posturas políticas que han caracterizado de manera paradigmática nuestro (...) devenir cultural son un correlato del modo en el que ha sido pensada la diferencia ontológica que supone el khorismós platónico.

The essay presents an interpretation of Hegel’s speculative sentence that, emphasizing the “counter-thrust” that the modern subject undergoes here, allows us to connect the movement of the Hegelian subject to the negativity recognised by Kant at the bottom of the faculty of judgment with regard to its aesthetic dimension. This way, it aims, first, to put into question the interpretation that sees in Hegel’s philosophy a regression with regard to the consciousness, attained by Kant, of the finitude, or the constitutive (...) split, of the modern subject, and, finally, in line with recent interpretations of Hegel, like those of Žižek or Malabou, to contribute to the questioning of the traditional interpretation of Hegel’s dialectics as the overcoming of negativity into a final reconciling synthesis.

Requiring family authorization for apnea testing subtracts health professionals control over death determination, a procedure that has traditionally been considered a matter of clinical expertise alone. In this commentary, we first provide evidence showing that health professionals’ (HPs) disposition to act on death determination without family’s prior consent could be much lower than that referred to by Berkowitz and Garrett (2020). We hypothesize that HPs may have reservations about their own expertise as regards death, and may thus hesitate to impose (...) their views on patients’ families. We then address the theoretical question of clinical expertise in death determination by distinguishing judgments about facts (e.g., the presence or absence of spontaneous breathing) from interpretations given of these facts (i.e., their meaning for the vital status of an individual). We argue that, while clinicians may claim some expert authority on the former, they hold no particular authority on the latter. (shrink)

Empirical political theory has grown in importance. In empirical political theory, attention to data is part of the evaluative step. A concern was raised that being attentive to the content of political science data implies that such attentiveness would limit the normative contours of empirical political theory, and will create a status-quo bias. This concern has been called the ‘problem of critical distance’. One way to appraise the significance of this problem is to examine the work done by empirical political (...) theorists such as Anderson (on racial integration), Wenar (on international trade), and Carens (on immigration). All three scholars suggest radical policies that differ from existing institutions and rules. The likelihood that a theory will suffer from the problem of critical distance will depend on the type of usage of data by a given theorist, her/his normative standpoint, and the manner in which they coalesce or differ.

"En faisant le choix d'un "gouverneur" plutôt que d'un "précepteur" pour éduquer Émile, Jean-Jacques Rousseau a introduit, dans la pensée éducative, des concepts qui avaient été jusque-là exclus des traités d'éducation. Dans les cours qu'il a donnés au Collège de France à partir de 1978, Michel Foucault s'est interrogé sur le problème de l'art de gouverner. Que signifie "gouverner selon la nature", et comment Rousseau envisage-t-il les questions éducatives dans ce qui relève, selon les termes de Foucault, du "gouvernement de (...) soi et des autres"?".

Educating young people about how to interact with patients at the end of their lives is challenging. A qualitative study based on Husserl’s phenomenological approach was performed to describe the learning experience of secondary education students after watching, analysing, and reflecting on two videoclips featuring Cameron Duncan, a young man suffering from terminal cancer. Students from three vocational centres providing training in ancillary nursing, pharmacy, and dependent care in the Community of Madrid visited the Palliative Care Hospital. A total of (...) 110 students, with a median age of nineteen years, participated in the study. The students’ learning experience through the videoclips reveals the essential aspects required in palliative care, since the character suffers in every dimension of his being: physically as well as psychologically, socially, and spiritually. Therefore, this requires healthcare professionals to understand their experience, putting themselves in their place, to provide affectionate care and to display communication skills leading to a quality helping relationship. Four comprehensive educational categories were identified in the study. The students learned the importance of: 1) providing comprehensive and affectionate care to patients, 2) the need for communication skills in caring for patients, 3) being aware of the end of life and time left, 4) valuing life and fighting for what one wishes to attain. A visit to a PC hospital and the viewing of videoclips and reflection upon these, represents a useful strategy for secondary education healthcare students. The study indicates that videoclips are an innovative method for becoming aware of the various issues pertaining to palliative care. (shrink)

In philosophy, as in any other theoretical endeavor, it is not rare to find conflicting but equally well grounded positions. Besides defending one of the positions and criticizing the other, philosophers can opt for pursuing other, more sophisticated, approaches aimed at incorporating the insights, intuitions, and arguments from both sides of the debate into a unified theory: Dialetheism, Analetheism, Gradualism, Pluralism and Relativism. The purpose of this article is to present each strategy's basic argumentative structure, relative strengths, and challenges, trying (...) to determine in which situations one is more appropriate than the others. Despite substantial differences between them, all four options have deep structural similarities; and which option is better for which dilemma or paradox will depend ultimately on a combination of epistemological, linguistic, and metaphysical factors.

Genetic relatedness figures heavily in contemporary ethical debates on egg freezing, although the arguments lack empirical‐based evidence. Rather than adding another theoretical view on the moral relevance of genetic connections, this paper instead proposes an empirically grounded perspective based on two independent qualitative interview‐based studies conducted in Belgium and France. Three themes emerge from our empirical data: (1) prioritizing family building; (2) centering the gestational experience of motherhood; and (3) identifying the complexities and limitations of adoption. These themes suggest that (...) the relationship between egg freezing, genetics, biological motherhood, and adoption is highly complex and less straightforward than what is often assumed in the egg freezing debate. Our study provides more detailed insights into women's ambivalent experiences regarding those reproductive options. We discuss the ethical implications of our empirical findings and hold that pursuing genetic desire is not necessarily the main moral reason why women freeze their eggs. (shrink)

Research on medical interactions shows how the discursive construction of the clinical case impacts diagnostic reasoning and treatment recommendations. Drawing on an ethnographic study in an intensive care unit, we illustrate how this process is at play in a ward that adopts an extreme, guideline-divergent policy as to the use of antibiotics. The article focuses on how physicians assemble the case as ‘treatable’ or ‘not yet treatable’, and how in doing so they ‘talk into being’ two contrastive policies on antibiotics (...) and position themselves toward the one adopted in the ward. The analysis identifies the discursive resources displayed by physicians to both project an infectious disease diagnosis and resist this treatment-implicative trajectory. We argue that the physicians’ contentious discursive construction of the case has crucial consequences in the way the ward’s extreme policy is jointly accomplished as a highly reflexive process sensitive to the contingencies of any particular case.

In lieu of an abstract, here is a brief excerpt of the content:Catholic Conscience and Civil Disobedience:The Primacy of TruthAngel Perez-Lopez and Israel Perez-LopezIntroductionSacred Scripture describes different examples of moral conscience dictating civil disobedience. For instance, think of the situation of Daniel (see Dan 6:6–10). In this and many other cases, we always find, above all, a defense of truth and of its primacy over conscience and civil authority.1 In a culture that rapidly abandons Christendom and rejects the (...) Catholic social values once prevalent, this same issue is gaining prominence.Recent civil mandates related to Covid-19 vaccination are raising anew the challenging moral question, among faithful Catholics, concerning the legitimacy of civil disobedience.2 Part of the difficulty consists in the struggle [End Page 773] to harmonize two statements from the Congregation for the Doctrine of the Faith (CDF) concerning the Covid-19 vaccines.On the one hand, it is affirmed that, under certain circumstances, the use of some of these vaccines is morally permissible: "When ethically irreproachable Covid-19 vaccines are not available (e.g. in countries where vaccines without ethical problems are not made available to physicians and patients, or where their distribution is more difficult due to special storage and transport conditions, or when various types of vaccines are distributed in the same country but health authorities do not allow citizens to choose the vaccine with which to be inoculated) it is morally acceptable to receive Covid-19 vaccines that have used cell lines from aborted fetuses in their research and production process."3On the other hand, the CDF also affirms that vaccination should be voluntary; it is not obligatory as a rule: "Practical reason makes evident that vaccination is not, as a rule, a moral obligation and that, therefore, it must be voluntary."4Some Catholics are clinging to the first affirmation to advocate for the primacy of authority in the civil mandate to be vaccinated. Others, instead, are clinging to the second affirmation to uphold the primacy of conscience and the right to civil disobedience. The controversy is reaching a boiling point in the United States. It seems that tertium non datur.In this essay, however, aided by the guidance of our moral magisterium and Thomas Aquinas, we would like to show how these two statements from the CDF are not incompatible. We would like to offer a third option to the ones previously described. Our thesis is that the way to bring about the harmony of both statements consists in underscoring the primacy of truth, in our comprehension of conscience, authority, and civil disobedience.The essay will be divided into two different sections. The first section deals with the general principles at play in the Catholic understanding of conscience and civil disobedience under the primacy of truth. Thus, it focuses on providing some needed information to get rid of the relativistic and political lenses through which many Catholics today are approaching the vaccine mandates. The second section of the essay is instead more particular. It makes a moral evaluation of the recent mandates to be vaccinated. [End Page 774]General PrinciplesToo Political?As Catholics, we should not be so radical as to think that moral theology has nothing to say about these political matters. A legitimate understanding of the separation between church and state does not forbid the Church's magisterial teaching and moral theology to be concerned with this issue.The Church is not only a mother but also a teacher: "The church's motherhood can never in fact be separated from her teaching mission, which she must always carry out as the faithful Bride of Christ, who is the Truth in person."5Moreover, "life in common within the State possesses a relevant moral value and presents specific demands that—according to the law of the Incarnation, though with a completely particular modality—enter in to form a part of the following of Christ. Therefore, moral theology must treat of it."6Thus, we would like to invite our readers to divest from political biases that may be influencing their reasoning. This is not about being Republican or Democrat first and then using one's faith to express our political views. The... (shrink)

RESUMEN Cuando se mira la masacre de El Salado, es difícil no preguntarse por los factores que llevaron a esta comunidad de los Montes de María, en el contexto de la guerra rural que vivía Colombia a finales del siglo XX, a volverse un objetivo militar por parte de las A.U.C. (Autodefensas Unidas de Colombia), es decir, a recibir la marca o estigma de 'pueblo guerrillero'; en otras palabras, a convertirse en un pueblo masacrable. El presente artículo intenta abordar esta (...) cuestión y para ello analiza las consecuencias de la ocupación de las FARC desde su ingreso a la región en los noventa. Los modos como este poder fareano dispuso de lógicas guerreristas y dejó poco margen de maniobra y libertad para los pobladores de El Salado; los saladeros no tuvieron opción ni libertad, y la cohabitación se confundió con la colaboración, la pasividad con la pertenencia. En una segunda parte, revisa los efectos de la arremetida brutal de las FARC contra cierto grupo de pobladores (en especial, ganaderos y fuerza pública); de algún modo, la masacre del 2000, ejecutada por las AUC, fue una respuesta impulsada por un odio desmedido frente a una violencia también excesiva por parte de las FARC en los años anteriores a la masacre. En este apartado, se habla acerca del odio y la venganza que se constituyen en afectos que contribuyeron decisivamente -entre otros más- a la masacre del año 2000. Las elaboraciones sobre la economía del odio de Sara Ahmed (2015) y las de Laura Quintana sobre los afectos (2020 y 2021) serán fundamentales. ABSTRACT When looking at the El Salado massacre, we wonder about the factors that led this town of los Montes de María, in the context of the rural war in Colombia at the end of the 20th century, to become a military objective by the A.U.C (Autodefensas Unidas de Colombia), that is, to receive the brand or stigma of 'guerrilla people'; that is, to become a massacrable town. This article tries to address this issue, thus analyzing the consequences of the FARC occupation since its entry into the region in the nineties. Ways like this Farean power had warmer logic and left little room for maneuver and freedom for the residents of El Salado; The saladeros had no choice or freedom, and cohabitation was confused with collaboration, passivity with belonging. in a second part, it reviews the effects of the brutal attack by the FARC against a certain group of residents (especially, ranchers and the military); in a way, the 2000 massacre, carried out by the AUC, was an inordinately hateful response to excessive violence by the FARC in the years before the massacre. In this section, we talk about the hatred and revenge that constitute elements that contributed decisively -among others- to the 2000 massacre. The elaborations on the economy of hate by Sara Ahmed (2015) and the elaborations of Laura Quintana on affects (2020 and 2021) will be fundamental. (shrink)

Resumen: El discurso de la economía ha transitado por una tensión entre pertenecer a una Ciencia Social y presentar rasgos prototípicos de una Ciencia Básica. Ahora bien, evidenciar esta hibridez desafía a los investigadores del lenguaje, sobre todo si estos textos son parte de la formación de un economista. Particularmente, el Informe de Política Monetaria no ha sido estudiado desde el punto de vista lingüístico, por lo que se busca observar, en un corpus de 45 textos, si el género IPOM (...) evidencia dicha tensión discursiva de la disciplina. Para lograr ese objetivo, se ha optado por una metodología basada en dos dimensiones: Contexto de Producción y Organización Retórico-Funcional. Tras el análisis, los hallazgos del corpus IPOM-2013 integradamente muestran que el género IPOM efectivamente evidencia dicha tensión con rasgos más características de la CB como es el uso de recursos matemáticos y, por otro lado, rasgos de la CS, asociados a la modalización del discurso en su macromovida central.: The discourse of economy has gone by a constant tension between belonging to a Social Science and present prototypical features of a Basic Science. However, evidence this hybridity poses a challenge for researchers of language, especially if these texts are part of the training of an economist. In particular, the Monetary Policy Report has not been studied from the linguistic point of view. In this context, this research search to answer the question whether the gender IPOM evidences such discursive tension of the discipline. To achieve this objective, it has opted for a methodology based on 2 dimensions: Production Context and Rhetorical-Functional Organization. After the analysis, the findings Integrally shows that the IPOM genre effectively demonstrates this tension with features more characteristic of the BS such as the use of mathematical resources and, on the other hand, SC traits, mainly associated to the modalization of the discourse in its central macromove.

Hume argued that inductive inferences do not have rational justification. My aim is to reject Hume’s argument. The discussion is partly motivated by an analogy with Carroll’s Paradox, which concerns deductive inferences. A first radically externalist reply to Hume (defended by Dauer and Van Cleve) is that justified inductive inferences do not require the subject to know that nature is uniform, though the uniformity of nature is a necessary condition for having the justification. But then the subject does not have (...) reasons for believing what she believes. I defend a moderate externalist account that seeks to partly accommodate that objection to the radical externalist proposal. It is based on an extension of Peacocke’s theory of concepts: possession conditions for predicative concepts standing for natural properties include (fallible) dispositions to project them to new cases in accordance with inductive inferential patterns.

Desde un recorrido por algunas de las transformaciones desarrolladas en la práctica religiosa cotidiana de distintas comunidades, producidas en los meses iniciales de la pandemia del COVID 19, se abordaron las respuestas de estas comunidades religiosas, mediadas por las Tics. La investigación tenía el objetivo de profundizar en los procesos de adaptación de los rituales y celebraciones religiosas, desde un acercamiento a los procesos de virtualización y digitalización. Asimismo, analizar el espacio que ocuparon los Mass Media en la formulación de (...) relatos sobre las prácticas religiosas en el contexto pandémico. Por último, comprender el papel que tuvieron las comunidades religiosas en la resolución de muchos de los conflictos e incertidumbres existenciales generadas durante ese período. En este sentido, quería dar respuesta a cuestiones cómo ¿Qué implicó la situación de Pandemia para las comunidades religiosas? ¿En qué medida podemos hablar de una redefinición de los espacios sagrados? ¿Qué lugar ocuparon las tecnologías a la hora de solventar las dificultades cultuales en las congregaciones religiosas? ¿Cuál fue el relato de los Mass Media sobre las prácticas de estas comunidades religiosas? Para dar respuesta a estas cuestiones se optó por la etnografía virtual de los espacios mediados por las Tics, y la realización de entrevistas para recoger las experiencias religiosas offline. Los resultados revelaron que la resiliencia mostrada por las personas de estas comunidades religiosas reflejaba su capacidad para reformular y redimensionar las prácticas religiosas, desde las herramientas digitales.

El objetivo del presente artículo es múltiple. Primero, pondera una serie de razones por las cuales la mística aún es relevante para el análisis de la condición humana del hombre actual. Segundo, propone a la promesa y a la ausencia como dispositivos de la mística. Tercero, expone, desde la lectura que hacen Alois Haas y Amador Vega de algunos sermones alemanes del Maestro Eckhart y de El peregrino querúbico de Angelus Silesius, los planteamientos fundamentales de la mística de estos autores, (...) a saber: el vaciamiento del alma, el coengendramiento, el abismo de Dios y la unión mística. Al mismo tiempo esboza cómo el pensamiento de Eckhart y Silesius, además de ser estudiado, produce ecos en algunas de las formulaciones filosóficas más importantes del siglo XX. The aim of this article is multiple. First, it weighs a series of reasons for which mysticism is still relevant for the analysis of man’s current human condition. Second, it proposes promise and absence as the devices of mysticism. Third, it exhibits, according to the reading of Alois Haas and Amador Vega of some of Meister Eckhart’s German sermons and Angelus Silesius’ The Cherubic Wanderer, the fundamental expositions of these authors’ mysticism, namely: voidance of the soul, co-conceivement, God’s abyss and mystical union. At the same time it outlines how the thought of Eckhart and Silesius, besides being studied, produces echoes in some of the most important philosophical formulations of the 20th century. (shrink)
