This special issue of Human Nature presents selected works from the 2015 and 2017 “Warfare, Environment, Social Inequality, and Pro-Sociability” conferences held at the Center for Cross-Cultural Study in Seville, Spain. These investigations explore the manifestations of indigenous warfare and violence from a host of theoretical perspectives. Topics range from the origins of warfare to the psychological repercussions of combat, the relationship between warfare and status, as well as the documentation of peace processes among warring groups. This issue also examines (...) the effects of militarization and coercive conservation on indigenous peoples. (shrink)

We employ the Social Signaling Model and life history of a Western Dani big-man, Tibenuk, to analyze a neglected curiosity in the career of the big-man type. The big-man is renowned as an economic entrepreneur, the master of material displays. In New Guinea, however, big-men had invariably first gained fame and some influence as eminent warriors. The SSM accounts for this two-part career path by proposing that small-scale social organization rests on honest, competitive signaling of individual and collective fighting strength, (...) with leaders being those who excel in these contests. The performances for which big-men are already known, conspicuous ceremonial displays, broadcast this strength indirectly. Explicitly conceptualized as symbolic fighting, they constituted indexical proxies for their sponsors’ individual and collective willingness and ability to fight. Success on the battlefield, though, signaled fighting strength more directly. Men therefore had to demonstrate strength on both the battlefield and the ceremonial ground if they were to become big-men. This was Tibenuk’s achievement. When he was young and at his physical peak, he demonstrated outstanding capability in war. War is a young man’s game, however, and as his physical capacities waned, he shifted to politics, an older man’s game, honing his political talents and developing extensive political networks that allowed him to sponsor massive pig feasts, the principal form of conspicuous ceremonial display. Tibenuk’s career also reveals synergies between warrior and political talents that hitherto have been overlooked in big-man analysis. (shrink)

IntroductionStress is associated with disease and reduced leukocyte telomere length. The objective of this research is to determine if self-perceived stress is associated with telomere length in Costa Rican adults and the gender differences in this association. Findings may help explain how some populations in apparent socioeconomic disadvantage and with limited access to specialized medical services have a remarkably high life expectancy.MethodologyData come from the pre-retirement cohort of the Costa Rican Longevity and Healthy Aging Study, a population based survey conducted (...) in the households to 2,327 adults aged 53 to 66 years. The DNA to measure LTL was extracted from blood cells in laboratories of the University of Costa Rica whereas the Blackburn laboratory at the University of California performed the telomere length measurement applying the quantitative polymerase chain reaction. The relationship between telomere length and perceived stress was measured using least-squares multiple regression. Perceived stress was measured by a set of questions about family, job, finances and, health reasons to be stressed. Models included the control variables: age and sex of the participant, whether he or she resides in the Nicoya area, a “blue zone” known for its high longevity, and the aforementioned sociodemographic, health and lifestyles characteristics.ResultsStress perception and LTL are significantly different by sex. Women perceived higher stress levels than men in almost all aspects studied, except work. Women have significantly longer telomeres. Shorter telomeres are significantly associated with caregiving stress in men and with parental health concerns in women. Counter-intuitive telomere lengthenings were observed among women who feel stressed about caring for family members; and among men who feel stressed due to their family relationships as well as concerns about their own health.DiscussionResults confirm that people with self-perceived stress due to caregiving or health issues have shorter telomeres. The relationship between stress and telomere length differs between men and women. Gender relations exert a strong modifier effect on the relationship between stress and LTL: gender is related to perceived stress, telomere length, and apparently also to the way stress and LTL are related.

This is the first publication on complete and stand alone arithmetization of bivalent logic.

El tema vertebrador como se indica en el título es el sentido de la vida. Se ofrece una serie de reflexiones sobre la relación de la persona con la matematización de la cultura. El conocimiento científico del mundo no es banal, sino que a partir de él la persona en su «voluntad de sentido» mira a esa realidad con la que interactúa. Adentrarnos en el significado de algunos fenómenos matemáticostecnológicos relacionados con la inteligencia artificial, captar los mensajes sociales que se (...) producen y penetrar en su sentido profundo puede ofrecernos claves para la comprensión (y auto-comprensión) de la persona en su estar en la sociedad actual.

En la literatura publicada a lo largo del siglo XX y lo que va del XXI encontramos de manera constante lo que podemos denominar una serie literaria sobre el tema de la homosexualidad. La historia literaria costarricense muestra, en los inicios del siglo XX, el caso de Jenaro Cardona, de manera particular con La esfinge del sendero (1914). Más adelante, apenas pasada la primera mitad de siglo, encontramos el caso de José León Sánchez con La isla de los hombre solos (...) (1963), en donde la homosexualidad es presentada como parte de los arrebatosy de la violencia carcelaria.Teníamos que llegar a las últimas décadas del siglo pasado para que, de alusiones que marginalizaban aún más todo lo que tuviera que ver con la sexualidad, se pasara a una nueva manera de comenzar a sacar del closet literario, ya no solo el tema de la homosexualidad, sino en general el de la sexualidad misma. El valor enunciativo de la publicación de esta literatura plantea una relectura del Estado costarricense mismo y del papel de sus instituciones. De ahí la significación de ese gesto fundante y provocador, producto de esta nueva serie de textos en la Costa Rica contemporánea, de una manera como no había sucedido antes en el país. (shrink)

The objective of this study is to explore and to verify the utility of the five moral foundations to differentiate between two understudied groups, namely, young offenders who use violence against their parents or dating partners, as well as to predict the extent to which these young people justify violence and perceive themselves as aggressive. Although both types of violence imply, by definition, harming someone and adopting a position of authority, we hypothesize a very different role for at least these (...) two moral foundations. Our results support this idea and show a much lower regard for the five moral foundations, including care and authority, in the child-to-parent violence group than in the dating violence group. Additionally, the authority foundation was able to increase the effectiveness of correctly classifying the participants in one group or the other by 29%. Finally, care and authority, along with fairness, served to predict justification of violence and self-perceived aggressiveness. The moral foundations approach provides preliminary evidence to better understand two specific types of youth violence and extract preventive educational and treatment strategies. (shrink)

Summary This paper provides an interpretation of the movement of Arendt's thought in her Denktagebuch, from 1950 to 1973. This movement results in an incipient political philosophy based on new concepts of freedom, equality, and solidarity. As a contribution to debates on the normative foundations of Arendt's political thought, the paper seeks to show that her incipient political philosophy is based on an ethical understanding of the human condition as constituted by its openness to the divine, the worldly, and the (...) (human) Other. Despite its fragmentary nature and its politically problematic indebtedness to theological traditions, Arendt's private thought nevertheless allows us to rethink her place in the history of European ideas. Beyond that, it also provides a powerful alternative to the view that ethical and political thought must remain ?political not metaphysical? (shrink)

A la hora de pensar lo más inmediato a nosotros mismos es necesario acudir a lo que somos en cuanto Dasein. Sin embargo, la experiencia de lo inmediato tiene la condición de presentarse bajo la forma de un extrañamiento, un «no saber». Se verá que la corporeidad y su extrañamiento abren a la posibilidad de una hermenéutica de nuestra propia condición porque la experiencia de lo Unheimlich es una vía de epojé que «detona» (revienta) la cadena de significaciones habitual y (...) reconfigura la experiencia. Se tomará como punto de referencia cuatro casos icónicos: 1) la convalecencia de Oliver Sacks, 2) el famoso caso Paul Schreber, 3) la referencia al joven esquizofrénico en los Seminarios de Zollikon, e incluso 4) el desfallecimiento de Heidegger entre los años 1945 y 1946, todo esto a la luz del extrañamiento de lo íntimo y la posibilidad que este abre a un «reordenamiento interno». En definitiva, las patologías y lo terrorífico que las acompaña son capaces de generar las condiciones de un vitalismo inusitado, pues solo quien se ha enfrentado a la más radical convulsión de todas sus verdades, podrá «abrirse camino» en medio del exceso de donación que desborda su «realidad».

El objetivo del estudio es evaluar el desempleo juvenil universitario en mujeres de 18 a 30 años, como consecuencia de los efectos de la pandemia en la salud pública. La metodología responde a un estudio de campo con una muestra de 239 casos analizados a través de una encuesta cerrada, basada en 26 ítem, mediante una escala Likert para contrastar las situaciones profesionales y humanas de las encuestadas relacionado a conciliación, igualdad y desarrollo profesional. Los resultados evidenciaron brechas en mujeres, (...) sobre lo cual se requiere fortalecer la participación de la mujer en espacios laborales. (shrink)

Este artículo busca avizorar, desde el terreno de las pretensiones del humanismo, la posibilidad de una ética desprovista de «centro» que se asiente en la «compasión». Se buscará comprender la necesidad de abandonar los intentos de retornar al proyecto «humanístico» y se señalará su mayor riesgo: el «cínico ilustrado». Adicionalmente, se considerará «el humanismo» como el solemne destello de una «estrella que murió hace mucho» pero que da señales para la construcción de una ética excéntrica fundada en la compasión y (...) el dolor. Para tales efectos, se presentarán tres secciones: a) el humanista un cínico ilustrado b) mecanismos de evasión. La miseria y el modo de vida burgués y c) la ausencia de centro y la posibilidad de una ética excéntrica. (shrink)

O presente artigo intenciona realizar uma breve investigação da relação dialética subjetividade-objetividade numa perspectiva emancipatória da classe oprimida. Com efeito, nosso objeto de estudo, a pedagogia do oprimido em Paulo Freire, será analisado numa perspectiva dialógica com o pensamento marxiano, com vistas a encontrar algumas marcas fundamentais da contribuição do filósofo alemão na constituição do ideário crítico freiriano. Destacamos aqui que o problema central da pesquisa, qual seja: a relação mundo e consciência, institui-se como problema indeclinável para o processo de (...) luta histórica e social. (shrink)

This paper aims to develop a brief analysis of spirituality in the Christian perspective from Luke 10.25-37, emphasizing the existing elective affinities between the notion of spirituality expressed in this narrative and the Ethics of Alterity in Emmanuel Levinas. The method used in this research is the literature review. For methodological reasons, this reflection was developed from the historical-critical exegetical process. The considerations found in this research line up to a prospect that the Other/Next assumes a vital place in the (...) spirituality of the Christian faith. Despite of the existing elective affinities between the Philosophy of Alterity and the Christian spirituality, the relationship between spirituality and ethics is a complex and essential drama for the search field of philosophy of religion.

Laureado com a designação de patrono da educação brasileira, Paulo Freire foi, seguramente, um icônico humanista cristão e um notável intelectual do século XX. A obra Pedagogia do oprimido desvela, de modo singular, a politicidade da educação. Em que se pese a natureza conceitual do problema, esse escrito se faz irredutível a qualquer forma de especulação impassível e estéril. A proposta pedagógica de Freire consiste numa educação dialógica, participante, problematizadora e emancipatória, na qual o oprimido possa libertar-se a si mesmo (...) das amarras da coisificação, para, assim, exercer sua própria vocação ontológica de “ser-mais”, de ser sujeito cognoscente, autor de sua própria história através da práxis. Com efeito, o projeto freiriano de uma pedagogia contextualizada, i.e., forjada a partir do oprimido, de sua própria linguagem e valores, se funda, necessariamente, na fé nas pessoas. Dito de outro modo, a confiança no povo é uma condição imprescindível para a própria revolução. (shrink)

Pouco antes de falecer, Jorge Luís Borges determinou que sua esposa, Maria Kodama, não pu­blicasse seus livros regionalistas de juventude em suas obras completas, que assim ficariam incompletas, uma decisão tipicamente borgiana. A viúva preferiu não cumprir a determinação e as obras editadas se tornaram completas, na medida em que possam ser descobertos manuscritos ainda inéditos. Elas revelam um amplo arco, correspondendo à sua longa vida, da juventude muito argentina e profundamente bonaerense, do seu país e cidade natal Buenos Aires, (...) ao mun­do. Os seus artigos, publicados mais em revistas literárias que jornais, desde cedo revelam esta vocação universal. Jorge Luís Borges escreveu com freqüência sobre autores estrangeiros. Depois, os próprios temas dos livros vão mudando dos regionalismos e até localismos, rumo às dúvidas e ambigüidades intrinsecamente humanas de todas as partes do mundo, onde ele as imaginariamente situa. Ao fim e ao cabo, Jorge Luís Borges – traduzido e homenageado em muitos países – preferiu morrer em Genebra e lá ser sepultado, onde estudara na adolescência, quando fora muito feliz na descoberta inicial de outras culturas. Elas demoraram a nele predo­minarem, mas terminaram acontecendo. Mesmo assim, ele no íntimo nunca deixou de todo a argentinidade. Crescentemente cosmopolita, o nacionalismo jamais abandonou por completo o espírito de Jorge Luís Borges. Sua atitude pró-britânica, durante a própria Guerra das Malvinas, pode ser interpretada como protesto e advertência diante de uma derrota próxima. (shrink)

La relación de la matemática con la realidad es una cuestión que ha interesado desde siempre a los matemáticos y a los profesores de matemáticas, unas veces se establece esta relación desde la historia, otras para motivar a los alumnos (y responder a la famosa cuestión "para qué sirven las matemáticas") o para situar la construcción de conceptos matemáticos y sus significado en experiencias concretas y en conexión con otras disciplinas y, otras veces, a través de los estudios internacionales comparativos (...) de evaluación.

It has often been noted that Leo Strauss developed his understanding of political philosophy through a critical engagement with Heidegger. Yet most analyses focus on Strauss’s American works while neglecting his earlier response during the crisis years of the Weimar Republic. The article seeks to overcome this limitation by ‘deconstructing’ Strauss’s American definitions of political philosophy in light of both his Weimar understanding of politische Wissenschaft and his 1922 discovery of Heidegger’s Aristotle. I argue that Strauss’s conception of political philosophy (...) originated in Heidegger’s subversion of the traditional distinction between theory and praxis. I thus propose a way to read Strauss from the start following his own changing views of that distinction. (shrink)

Among the great philosophers of the twentieth century, only one, perhaps, shared Leo Strauss’s understanding of “ideas” as fundamental problems: his teacher Husserl. Throughout his work, Strauss heeded Husserl’s call to return to the “things themselves” and “the problems connected with them.” I argue that “natural right” is one such phenomenon or problem which Strauss seeks to recover—and reactivate—from centuries of sedimented interpretations. I further propose that “natural right” may be a “sense-formation” analogous to Husserl’s “geometry.” If this is true, (...) Natural Right and History may be modeled on Husserl’s Crisis of European Sciences. (shrink)

Although the majority of literature has shown undistinguishable attentional effects when eye-gaze and arrows are used as cues, recent research has found that whereas eye-gaze selectively orient attention to the specific location or part of the object looked at, arrows unselectively direct attention towards parts of the environment. However, it is unclear whether this dissociation between gaze and arrow cues is related to social cognitive mechanisms such as the attribution of mental states (Theory of Mind, ToM). We aimed at replicating (...) the dissociation between gaze and arrow cues and investigating sex differences in attentional object selection triggered by these two types of stimuli. While we replicated the arrow-gaze dissociation, this was equivalent in the male and female population. This finding seems to run counter the intuition that theory of mind abilities can account for the dissociation observed between gaze and arrow cues since greater ToM abilities have been generally shown in females. However, this conclusion it must be interpreted with caution since no differences in ToM abilities and autistic quotient scores were observed between male and female in our sample. Further research is needed to shed light on this issue. (shrink)

En este artículo se planteará, siguiendo a Heidegger, que el nihilismo, lejos de ser una consecuencia devastadora del tiempo de crisis es más bien una donación de este que posibilita realmente el acontecimiento del «pensar». En ese horizonte de significación se examinarán los orígenes de la palabra nihilismo y se abordará el nihilismo como espacio que prepara el acontecimiento del despliegue [Entfaltung] del ser. Por último, se estudiará brevemente la frase de difícil interpretación «solo un dios podrá salvarnos» pronunciada por (...) Heidegger en una entrevista en la revista Spiegel. (shrink)
