Utilizando como referencia la Carta política escrita por el general Pedro Alcántara Herrán a Bartolomé Calvo, en el contexto de la guerra civil colombiana de 1859-1862, en este artículo se analizan las relaciones existentes entre la negociación de la paz, la justicia y la regulación de la guerra. Se pretende mostrar que en el siglo xix las iniciativas políticas para evitar, suspender, limitar o terminar la guerra fueron tan abundantes y plurales como los levantamientos y las confrontaciones armadas. Además de (...) presentar la especificidad anómala del caso colombiano, donde históricamente coexisten y se entremezclan los llamados a la guerra con los propósitos de la reconciliación, el artículo rescata, para la actualidad, un documento histórico que sintetiza el lenguaje de la paz, la concordia y la reconciliación en una de las más largas y crueles guerras civiles decimonónicas.

El análisis propuesto en este texto señala que, en el proceso de imaginar y hacer posible la nación moderna en la América hispánica, el Libertador Simón Bolívar invocó el origen cívico y revolucionario de los nacientes Estados, y no la uniformidad etnocultural. En este aspecto, su postura fue radicalmente moderna y antigenealógica, en tanto afirmó que la unidad del carácter que supone la nación como comunidad política no tiene que coincidir, necesariamente, con los límites de las nacionalidades. Este artículo toma (...) como referencia el Discurso de Angostura, pronunciado por el Libertador en 1819, para mostrar que, al momento de construir esa gran nación que se debía llamar Colombia, Bolívar apeló a premisas políticas y territoriales, y no a los presupuestos nacionalistas de igualdad lingüística, racial o cultural. En tal sentido, su propuesta constitucional se inscribe en la tradición del patriotismo republicano y el ideal de la nación de ciudadanos. (shrink)

Resumen: Este trabajo ofrece evidencia empírica a la premisa que sostiene que el acercamiento teórico y metodológico de la Lingüística al estudio de géneros del ámbito profesional, no ha tenido el mismo énfasis que el académico (Cassany y López, 2011; Montolío & López, 2010; Autor, 2016; Lillis, 2021). En este sentido, el objetivo de esta investigación fue describir el estudio de los géneros profesionales entre 2008 y 2017 en las 10 principales revistas de Lingüística en América Latina. Para (...) ello se utilizó un enfoque mixto en un corpus de 1.729 publicaciones. Los resultados indican que solo el 1,85% de los estudios abordan géneros profesionales, principalmente, acerca de Artículos de Investigación Científica (36,3%), Sentencias Judiciales (27,2%) y Noticias (18,1%), lo que evidencia un reto pendiente que tiene hasta hoy la Lingüística. Abstract: This paper provides empirical evidence to the premise that the theoretical and methodological approach of Linguistics to the study of genres of the professional field has not had the same emphasis as the academics ones (Cassany & López, 2011; Montolío & López, 2010; Author, 2006, Lillis, 2021). In this sense, the objective of this research was to describe the study of professional genres between 2008 and 2017 in the 10 leading journals of Linguistics in Latin America. For this, a mixed approach was used in a corpus of 1,729 publications. The results indicate that only 1.85% of the researchs analizes professional genres, mainly about Articles of Scientific Research (36.3%), Judicial Sentences (27.2%) and News (18.1%), which evidences a pending challenge in Linguistics.

The World Health Organization has declared a world pandemic due to COVID-19. In response, most affected countries have enacted measures involving compulsory confinement and restrictions on free movement, which likely influence citizens' lifestyles. This study investigates changes in health risk behaviors with duration of confinement. An online cross-sectional survey served to collect data about the Spanish adult population regarding health behaviors during the first 3 weeks of confinement. A large sample of participants from all Spanish regions completed the survey. Binomial (...) logistic regressions adjusted for socioeconomic characteristics, body mass index, previous HRBs, and confinement context were conducted to investigate associations between the number of weeks confined and a set of six HRBs. When adjusted, we observed significantly lower odds of experiencing a higher number of HRBs than before confinement overall in a time-dependent fashion: OR 0.63; 95% CI: 0.49–0.81 for the second and OR 0.47; 95% CI: 0.36–0.61 for the third week of confinement. These results were equally consistent in all age and gender subgroup analyses. The present study indicates that changes toward a higher number of HRBs than before confinement, as well as the prevalence of each HRB except screen exposure, decreased during the first 3 weeks of COVID-19 confinement, and thus the Spanish adult population may have adapted to the new situational context by gradually improving their health behaviors.

In this paper we develop a view about the disorientation attached to the process of falling out of love and explain its prudential and moral value. We start with a brief background on theories of love and situate our argument within the views concerned with the lovers’ identities. Namely, love changes who we are. In the context of our paper, we explain this common tenet in the philosophy of love as a change in the lovers’ self-concepts through a process of (...) mutual shaping. This, however, is potentially dangerous for people involved in what we call ‘subsuming relationships’, who give up too much autonomy in the process of mutual shaping. We then move on to show how, through the relation between love and the self-concept, we can explain why the process of falling out of love with someone is so disorientating: when one is falling out of love, one loses an important point of reference for self-understanding. While this disorientating process is typically taken to be harmful to the person experiencing it, we will explain how it can also have moral and prudential value. By re-evaluating who we were in the relationship and who we are now, we can escape from oppressive practices in subsuming relationships. We finish by arguing that this gives us reason to be wary of seeking to re-orient ourselves -or others- too quickly after falling out of love. (shrink)

A group of philosophers suggests that a sense of mineness intrinsically contained in the phenomenal structure of all conscious experiences is a necessary condition for a subject to become aware of himself as the subject of his experiences i.e. self-awareness. On this view, consciousness necessarily entails phenomenal self-awareness. This paper argues that cases of delusions of thought insertion undermine this claim and that such a phenomenal feature plays little role in accounting for the most minimal type of self-awareness entailed by (...) phenomenal consciousness. First, I clarify the main view endorsing this claim i.e. the Self-Presentational View of Consciousness and formulate the challenge from thought insertion. After, I offer a systematic evaluation of all the strategies used by the advocates of this view to deal with this challenge. Finally, I conclude that most of these strategies are unsatisfactory for they rest in unwarranted premises, imprecisions about the agentive nature of cognitive experiences, and especially, lack of distinction between the different ways in which subjects can become aware of their own thoughts.

RESUMEN La medicina tradicional herbolaria desde su evolución hasta la contemporaneidad ha sido objeto de uso para la medicina convencional. Por eso el objetivo del trabajo es describir el comportamiento de la medicina tradicional herbolaria en los sistemas de salud convencionales. Se realizó la búsqueda y análisis documental de numerosas fuentes sobre la temática pertenecientes a las bases de datos SciELO Cuba, SciELO Regional, Science Direct, Clinical Key, Cumed, Lilacslo. Se concluye que la actualidad social registra manifestaciones alentadoras en el (...) campo de la aceptación de la herbolaria como medicina complementaria por el equipo de salud y un renovado interés en el ámbito mundial por estudiar los efectos que tienen las plantas sobre la salud. ABSTRACT The traditional herbalist medicine from its evolution to the contemporaneity has been an object use for the conventional medicine. That's why the objective of the work is to describe the behavior of the traditional herbalist medicine in the conventional health systems. A search and documentary analysis of numerous sources on the subject-matter belonging to the databases SciELO Cuba, SciELO Regional, Science Direct, Clinical Key, Cumed, Lilacslo was carried out. It is concluded that the social actuality registers encouraging declarations in the field of the acceptance of the herbalist as complementary medicine for the team of health and a renewed interest in the world ambience to study the effects that have the plants on the health.

Why does social injustice exist? What role, if any, do implicit biases play in the perpetuation of social inequalities? Individualistic approaches to these questions explain social injustice as the result of individuals’ preferences, beliefs, and choices. For example, they explain racial injustice as the result of individuals acting on racial stereotypes and prejudices. In contrast, structural approaches explain social injustice in terms of beyond-the-individual features, including laws, institutions, city layouts, and social norms. Often these two approaches are seen as competitors. (...) Framing them as competitors suggests that only one approach can win and that the loser offers worse explanations of injustice. In this essay, we explore each approach and compare them. Using implicit bias as an example, we argue that the relationship between individualistic and structural approaches is more complicated than it may first seem. Moreover, we contend that each approach has its place in analyses of injustice and raise the possibility that they can work together—synergistically—to produce deeper explanations of social injustice. If so, the approaches may be complementary, rather than competing. (shrink)

Social Education implies a constant exposition to human experiences of vulnerability and suffering. In this paper, Levinas’s philosophy of alterity and, specifically, the notion of hospitality constitutes our ethical lens to explore educational encounters in non-formal contexts within the Spanish Social Sector. The study is developed from a hermeneutic phenomenological approach into the depth of lived experiences of eight social educators who currently work with different populations groups. The testimonies, explored through semi-structured interviews, are presented in a conversational, dialogic, poetic (...) format. First, Levinas’ philosophy is presented as our ethical position, focusing on subjectivity as hospitality. Secondly, methodological aspects regarding hermeneutics are addressed. Finally, the testimonies of social educators are presented in an evocative way, exploring uncertainty and three different tensions regarding human relations in their practices: physical spaces, affection, and embodiment.

In this article, I revise the normative account of sport that I proposed in ‘William J. Morgan’s “conventionalist internalism” approach. Furthering internalism? A critical hermeneutical response.’ I first present Habermas’ discursive ethics, placing emphasis on his interpretation of the relationship between moral (Kantian) and ethical (Hegelian/hermeneutical) principles. Then, I provide a reformulation of my account by both drawing on Habermas and going beyond him—as I go beyond Habermas, I will refer to the account as ‘discourse-ethics based.’ To further explore the (...) normative potential of the account, I connect its main tenets to the three main normative theories of sport (formalism, broad internalism, and deep conventionalism) and illustrate it with examples from anti-doping governance.

One of the best known arguments against the connectionist approach to artificial intelligence and cognitive science is that neural networks are black boxes, i.e., there is no understandable account of their operation. This difficulty has impeded efforts to explain how categories arise from raw sensory data. Moreover, it has complicated investigation about the role of symbols and language in cognition. This state of things has been radically changed by recent experimental findings in artificial deep learning research. Two kinds of artificial (...) deep learning networks, namely the convolutional neural network and the generative adversarial network have been found to possess the capability to build internal states that are interpreted by humans as complex visual categories, without any specific hints or any grammatical processing. This emergent ability suggests that those categories do not depend on human knowledge or the syntactic structure of language, while they do rely on their visual context. This supports a mild form of empiricism, while it does not assume that computational functionalism is true. Some consequences are extracted regarding the debate about amodal and grounded representations in the human brain. Furthermore, new avenues for research on cognitive science are open. (shrink)

Classic conceptions of model simplicity for machine learning are mainly based on the analysis of the structure of the model. Bayesian, Frequentist, information theoretic and expressive power concepts are the best known of them, which are reviewed in this work, along with their underlying assumptions and weaknesses. These approaches were developed before the advent of the Big Data deluge, which has overturned the importance of structural simplicity. The computational simplicity concept is presented, and it is argued that it is more (...) encompassing and closer to actual machine learning practices than the classic ones. In order to process the huge datasets which are commonplace nowadays, the computational complexity of the learning algorithm is the decisive factor to assess the viability of a machine learning strategy, while the classic accounts of simplicity play a surrogate role. Some of the desirable features of computational simplicity derive from its reliance on the learning system concept, which integrates key aspects of machine learning that are ignored by the classic concepts. Moreover, computational simplicity is directly associated with energy efficiency. In particular, the question of whether the maximum possibly achievable predictive accuracy should be attained, no matter the economic cost of the associated energy consumption pattern, is considered.

Para definir un nuevo horizonte del pensar originario, para establecer posibles salidas a la tan enunciada crisis de lo humano y la cultura, es necesario convocar la tarea de repensar las viejas cuestiones metafísicas en una nueva forma. En la actualidad se asiste a una tarea de reflexión tanto en la filosofía como en las humanidades, que convoca una nueva manera de entender el pensar sin los vestigios de la racionalidad instrumental. Es al emprender esta tarea renovadora del sentido humano (...) que el llamado giro teológico de la fenomenología aporta la relación mística-pensamiento, pensar-acontecer, y restablece la dimensión originaria de lo dado. Dominique Janicaud considera que la fenomenología francesa contemporánea ha hecho un giro teológico al introducir al Dios judeocristiano en la fenomenología; pero realmente se ha dado un giro hacia la razón mística redescubriendo el neoplatonismo de Dionisio Areopagita, la interioridad de San Agustín y el pensamiento del último Heidegger.

I’m at the playground with my baby, and a smiling adult inquires, “Is it a boy or a girl?” Scientific studies show that if I say X, they will see my baby as doing A, being A, feeling A—versus if I say Y.1 They’ll likely make different assumptions about whether my baby is able to climb up the playground structures and sit without support, and they’ll encourage my baby to engage in different activities.2 And of course, they’ll respond to them (...) differently depending on whether they think the baby is a boy or a girl. What do I do if I don’t want that to happen? One way to respond to the question is not to reveal the gender, or rather, to reject the assumption that my baby already has a gender, which is arguably a weird move, breaking out of a smoothly functioning, well-oiled social exchange. Here I want to talk about this weird move: How weird it is? What are some of the reasons to make the move anyway, and what are some of the concerns? (shrink)

Resumen Atendiendo a la lógica estándar, solo uno de los cinco indemostrables propuestos por Crisipo de Solos es realmente indemostrable. Sus otros cuatro esquemas son demostrables en tal lógica. La pregunta, por tanto, es: si cuatro de ellos no son verdaderamente indemostrables, por qué Crisipo consideró que sí lo eran. López-Astorga mostró que si ignoramos el cálculo proposicional estándar y asumimos que una teoría cognitiva contemporánea, la teoría de la lógica mental, describe correctamente el razonamiento humano, se puede entender (...) por qué Crisipo pensó que todos sus indemostrables eran tan básicos. No obstante, en este trabajo trato de argumentar que la teoría de la lógica mental no es el único marco que puede explicar esto. En concreto, sostengo que otra importante teoría sobre el razonamiento en el presente, la teoría de los modelos mentales, también puede ofrecer una explicación al respecto.According to standard logic, only one of the five indemonstrables proposed by Chrysippus of Soli is actually indemonstrable. The other four schemata are demonstra-ble in that logic. The question hence is, if four of them are not really indemonstrable, why Chrysippus considered them to be so. López-Astorga showed that, if we ignore standard propositional calculus and assume that a current cognitive theory, the mental logic theory, truly describes human reasoning, it can be explained why Chrysippus thought that all of his indemonstrables were so basic. However, in this paper, I try to argue that the mental logic theory is not the only framework that can account for that. In particular, I hold that another important reasoning theory at present, the mental models theory, can offer an explanation in that regard as well. (shrink)

Research investigating female gaming is relatively scarce, and past research has demonstrated that men are more likely to be problematic gamers. Few studies have focused on female gamers in community samples, and those that have been published have mainly collected data qualitatively in Europe. There is case study evidence suggesting clinicians are increasingly treating problem female gamers. The aim of this study is threefold: (i) to establish an international female gamer profile, (ii) to determine predictors associated with perceived internet gaming (...) disorder (IGD), and (iii) to identify those who are potentially at risk of developing gaming addiction and its characteristics by applying a quantitative approach. A cross-sectional online survey was applied through international gaming forums recruiting 625 female gamers, assessing sociodemographics, gaming devices used and play genres, and a set of questionnaires on gaming (e.g., problem online gaming [e.g., the nine-item short-form scale to assess IGD: IGDS9-SF], female stereotypes [e.g., sex role stereotyping scale], and psychological symptoms [e.g., Symptom CheckList-27-plus]). Female gamers from all continents reported the use of all videogames, especially popular online games using computers and consoles. The proportion of gamers with potential IGD was one per cent. Regression analyses identified several risk factors for increased scores on the IGDS9-SF, namely having achievement and social motivations, embodied presence and identification with the avatar, hostility and social phobia together with negative body image, playing Multiplayer Online Battle Arena, Massively Multiplayer Online Role-Playing Games, and First-Person-Shooter games. Findings contribute to filling the gap in knowledge on female gaming, to aid in the applicability of problematic gaming measurements in female gamers, especially those who are at risk of problematic gaming. The purpose of this study is to enhance the validity of the current measures to diagnose problem gaming appropriately in both genders. (shrink)

RESUMEN Se discute cómo pueden dos filósofos islámicos sostener que la generación del cuerpo es necesaria para que se origine el alma y, al mismo tiempo, afirmar que ésta puede separarse del cuerpo, ya sea transformándose en un intelecto inmaterial -en el caso de al-Fārābī-, o bien en un alma individuada e inmortal -en el caso de Avicena. El primero es cercano al hilemorfismo peripatético; el segundo adopta un dualismo robusto. Se argumenta que la integración de la cosmología, la biología (...) y la noética conduce, en ambos casos, a una reconciliación coherente entre el origen natural del alma y su inmaterialidad. ABSTRACT The article discusses how it is possible for two Islamic philosophers to claim that the generation of the body is necessary for the soul to arise, and, at the same time, to affirm that the latter can separate from the body, whether by becoming an immaterial intellect -in the case of al-Fārābī-, or an immortal, individual soul -in the case of Avicenna. While the former is close to Peripatetic hylemorphism, the latter adopts a robust dualism. The paper argues that the integration of cosmology, biology, and noetics leads, in both cases, to a coherent reconciliation between the natural origin of the soul and its immaterial nature. (shrink)

Nozick's well-known Experience Machine argument can be considered a typically successful argument: as far as I know, it has not been discussed much and has been widely seen as conclusive, or at least convincing enough to refute the mental-state versions of utilitarianism. I believe that if his argument were conclusive, its destructive effect would be even stronger. It would not only refute mental-state utilitarianism, but all theories considering a certain subjective mental state as the only valuable state. I shall call (...) these theories "mental state welfarist theories." I do not know whether utilitarianism or, in general, mental-state welfarism is plausible, but I doubt that Nozick's argument is strong enough to prove that it is not. (shrink)

El presente artículo tiene como propósito presentar una reflexión pedagógica mediante la aplicación de referentes del pensamiento de Juan José Bautista, discípulo de Enrique Dussel. Se busca repensar en términos epistemológicos la enseñanza del locus de enunciación latinoamericano.

Es por eso que este artículo (...) busca introducir la reflexión sobre los compromisos que implican pensar y pertenecer a esta zona geográficamente diversa. (shrink)

El materialismo de la Edad Moderna nos describe al hombre como una máquina, comparable a un complejo artilugio mecánico. Cabe entonces imaginar que una máquina no-biológica pueda constituir un ser pensante como lo son los seres humanos, e incluso cabría pensar en la posibilidad de codificación de una mente humana real para su posterior trasvase a un sustrato artificial. Considero que estas últimas posiciones son más propias de la cultura friki o de amantes de la ciencia ficción que de una (...) cultura humanista seria. En cualquier caso, una cosa parece clara: la simulación por ordenador de cualquier tipo de materia no es la materia misma. Una simulación por ordenador de una estrella no emite luz ni calor, y del mismo modo tampoco ofrece calor humano (en términos materiales) ni voluntad de vivir una máquina que hipotéticamente pueda contener toda la información sobre el ser humano y simular sus respuestas. -/- English translation: The materialism of the Modern Age describes human beings as machines, comparable to complex mechanical devices. It is then possible to imagine that a non-biological machine can constitute a thinking being as humans are, and one could even think of the possibility of coding a real human mind for its subsequent transfer to an artificial substrate. I think that these latter positions are more typical of the geek culture or of science fiction lovers than of a serious humanist culture. In any case, one thing seems clear: the computer simulation of any type of matter is not the matter itself. A computer simulation of a star does not emit light or heat, and likewise a machine that hypothetically can contain all the information about a human being and simulate his/her responses offers neither human heat (in material terms) nor will to live.

The spirit of the Second Vatican Council can be expressed in three terms that summarize its tremendous effort: faithful, pastoral and modern. In this spirit, the Church sought to deal with doctrinal questions in a new way, preferring mercy to severity. In agreement with this spirit of the Council, Paul VI transformed the Congregation of the Holy Office into the Congregation for the Doctrine of Faith and suppressed the Index of prohibited books. The inclusion of many modern philosophers shows that (...) the relation between modern philosophical thought and Catholic theology has been difficult, most likely due to the principle of immanence at the heart of modern thought. The article, then, analyzes and evaluates the metaphysical, gnoseological and ethical themes that stem from the assumption of the principle of immanence in some modern philosophers. However, the suppression of the Index shows that the essential continuity, faithfulness to the faith, is able to be accompanied by the accidental reform, as pastoral requirement and modernization.

We used to think it was the job of a historian of Spanish science to combat the negative evaluations of Hispanic cultures that came to be known as the Black Legend. Paradoxically, attempts to amend dominant narratives of the history of science so that they might accommodate Spain bolstered the very stories we meant to dismantle. Caring about the Black Legend deformed the history we were trying to write and never convinced the people we hoped to sway. In this article, (...) we provide an overview of the historiographic tendencies that most shaped our careers – responses to the Black Legend, such as contributionist history and bibliometrics – and explain why we have chosen to move on.

Una nueva edición del texto griego salió a la luz en 1999 y otra más está en preparación.

El libro completo reporta los testimonios de al menos ochenta y cinco personalidades que hicieron parte del panorama intelectual de la antigua Grecia. De cada una de esas personalidades se dan tanto noticias sobre su vida como resúmenes de su actividad filosófica y ci-tas presuntamente literales de sus obras. (shrink)

Jean Améry, superviviente de la Shoá, experimentará durante dos décadas la clausura de la palabra, como consecuencia traumática de la violencia y la tortura padecidas. Desde mediados de los años sesenta hasta su muerte, Améry se ocupará ensayística y literariamente de la destrucción infligida a él. Su empresa narrativa será el esfuerzo titánico por subvertir el “topos de inaplicabilidad”, asociado con el recuerdo del dolor extremo, determinante para su condición de víctima, mediante la palabra. una palabra capaz de devolverle –siempre (...) de modo parcial y subsidiario– la condición de sujeto. Sin embargo, la experiencia del dolor será inaprehensible, subsumida por el tiempo en la etérea forma de una abstracción. La memoria se revela a Améry como incapaz frente a la substancia del dolor, tan solo asequible a recurrentes escenas de penosa claridad para la visión. (shrink)

The aim of this article is to argue that a temporal asymmetry may be established within the framework of quantum field theory, independently of any violation of CP, and thereby T, in weak interactions, and independently of the property of time reversal invariance that its dynamical equations instantiate. Particularly, I shall argue that the temporal asymmetry can be stemmed from assessing the links between the proper group of symmetries of the theory and the ontology of the theory: arguments applied to (...) establish which elements and magnitudes remain invariants under group transformations can also be used to establish a temporal asymmetry.

The ethics of using genetic engineering to enhance athletic performance has been a recurring topic in the sport philosophy and bioethics literature. In this article, we analyze the ethics of cloning horses for polo competition. In doing so, we critically examine the arguments most commonly advanced to justify this practice. In the process, we raise concerns about cloning horses for polo competition, centering on normative aspects pertaining to sport ethics usually neglected by defenders of cloning. In particular, we focus on (...) how this practice could have a detrimental impact on the central skills of polo, and how it unjustly creates an uneven playing field. We suggest that the polo community would benefit from critically considering the ethical quandaries posed by the practice of cloning horses for polo competition. (shrink)

De Dreu and Gross offer a compelling synthesis of a growing literature on the psychology of attack and defense. I argue that human raiding ecology suggests the need to endogenize attacker-defender move order as well as opportunities for tactical mismatch available to defenders. Perhaps most significantly, I draw attention to the surprising lacunae in sex differences across attack and defense.

La descripción del itinerario investigador de la biología de las células troncales permite una reflexión sobre la racionalidad de la creatividad científica. En 1998 aparecieron las células troncales procedentes de embriones humanos. Inmediatamente llegaron, motivadas por razones ideológicas, políticas y económicas, las especulaciones sobre sus posibilidades terapéuticas. Pero las dificultades para su uso médico resultaron insuperables. En 2007 aparecieron las células troncales humanas de pluripotencialidad inducida (iPS). Esta trayectoria investigadora revela aspectos claves del pensamiento creativo en ciencia: a) La importancia (...) de la motivación ética para encontrar un punto de partida no destructivo que marca la racionalidad del camino: los procesos fisiológicos ocurren en la unidad de un organismo vivo. b) La necesidad de un conocimiento profundo de la experiencia científica acumulada para escoger la vía más natural. c) La visión de futuro que agota las posibilidades que ofrecen las pruebas en animales, y que encuentra aplicaciones útiles a los conocimientos que se van obteniendo. d) La imprescindible responsabilidad sobre las consecuencias.
