Hoy los programas de investigación socio-ecológica a largo plazo existen en por lo menos 32 países (esto es, los miembros de la Red Internacional de Investigación Ecológica a Largo Plazo o ILTER (International Long Term Ecological Research). Sin embargo, la consolidación de la red internacional dentro del paradigma de investigación socio-ecológica a largo plazo todavía requiere: (1) inclusión de algunas regiones remotas del mundo que aún están poco representadas, como el suroeste de América del Sur; (2) modificaciones en el tipo de investigación realizado, tales como la integración de las ciencias sociales y naturales con las humanidades y la ética, y (3) la incorporación de las conclusiones y resultados dentro de los procesos sociales y políticos. En este contexto, la naciente red de investigación socio-ecológica a largo plazo en Chile, que se extiende en el rango latitudinal más largo de bosque templado en el Hemisferio Sur, agrega una nueva región remota a las investigaciones ecológicas de largo plazo que había sido pasada por alto anteriormente. Además, la colaboración con la Universidad de North Texas y otros asociados internacionales ayuda a desarrollar un enfoque interdisciplinario para integrar las ciencias ecológicas y la filosofía ambiental, junto con los conocimientos ecológicos tradicionales, la educación informal y formal, la política, las humanidades, los procesos socio-políticos y la conservación biocultural.

Whereas intersectionality presents a fruitful framework for theoretical and empirical research, some of its fundamental features present great confusion. The term ‘intersectionality’ and its metaphor of the crossroads seem to reproduce what it aims to avoid: conceiving categories as separate. Despite the attempts for developing new metaphors that illustrate the mutual constitution relation among categories, gender, race or class keep being imagined as discrete units that intersect, mix or combine. Here we identify two main problems in metaphors: the lack of (...) differentiation between positions and effects and the problem of reification. We then present a new metaphor that overcomes these two problems: a basket of apples. We argue that considering social positions as the diverse properties of different apples avoids reification by considering categories as properties and not as objects themselves, and at the same time it allows us to think about the effects dimension from a plural and contextual approach. With this shift, we propose a reframing of the discussion in debates on intersectionality theory on the relation among categories, their in/separability and fragmentation. (shrink)

Bertrand Russell se guió en esta obra por el más ajustado sentido de la unidad histórica y estudió a cada filósofo en relación con el medio en que actuó, teniendo siempre en cuenta las circunstancias sociales y políticas de su época. En este primer volumen se analizan la filosofía presocrática, las aportaciones de Sócrates, Platón y Aristóteles, la filosofía helenística y a los Padres de la primera filosofía católica. Jesús Mosterín analiza en su Prólogo la trayectoria biográfica y la evolución (...) del pensamiento de este gran filósofo: su rebelión contra el idealismo vigente; el desarrollo del logicismo aplicado a las matemáticas y al conocimiento empírico; su faceta de filósofo práctico y su trabajo en la historia de la filosofía que tendrá como resultado esta obra.

Inauguration speech at chair number 18 of the Brasilian Academy of Philosophy.

An individual's health, genetic, or environmental-exposure data, placed in an online repository, creates a valuable shared resource that can accelerate biomedical research and even open opportunities for crowd-sourcing discoveries by members of the public. But these data become “immortalized” in ways that may create lasting risk as well as benefit. Once shared on the Internet, the data are difficult or impossible to redact, and identities may be revealed by a process called data linkage, in which online data sets are matched (...) to each other. Reidentification, the process of associating an individual's name with data that were considered deidentified, poses risks such as insurance or employment discrimination, social stigma, and breach of the promises often made in informed-consent documents. At the same time, re-ID poses risks to researchers and indeed to the future of science, should re-ID end up undermining the trust and participation of potential research participants. The ethical challenges of online data sharing are heightened as so-called big data becomes an increasingly important research tool and driver of new research structures. Big data is shifting research to include large numbers of researchers and institutions as well as large numbers of participants providing diverse types of data, so the participants’ consent relationship is no longer with a person or even a research institution. In addition, consent is further transformed because big data analysis often begins with descriptive inquiry and generation of a hypothesis, and the research questions cannot be clearly defined at the outset and may be unforeseeable over the long term. In this article, we consider how expanded data sharing poses new challenges, illustrated by genomics and the transition to new models of consent. We draw on the experiences of participants in an open data platform—the Personal Genome Project—to allow study participants to contribute their voices to inform ethical consent practices and protocol reviews for big-data research.

The present article explores the epistemological conditions of intercultural encounters. Based on an analysis of Raimon Panikkar's intercultural hermeneutics, we argue that intercultural encounters cannot take place adequately when they are based on purely rhetorical rationality or rational persuasion. We point to the limitations of grounding intercultural relationships on dialectical dialogue and, therefore, of educating them by simply enhancing discursive capacities. We underline the need for other epistemological conditions that should be fostered in order to move forward on the path (...) to actual interculturality. These can be summarised by what Panikkar calls "conversion", an epistemic framework of love—personal relationality, that goes beyond objectifying rationality—for the communication between (culturally different) subjects. We conclude that the culturally diverse human condition refers to being encountered and being understood on a level that is not merely logical or linguistic. What can be understood of a person with another cultural background goes beyond what can be comprehended by logical rationality or captured by veritative judgements about objects. In other words, in intercultural encounters, ontological, rather than merely logical truth is at stake, which means that the presence of the other can lead to experiences of meaning: it reveals a being that calls for conversion. Conversion demands an ontic action on the part of the subject, not merely an epistemological one, that cancels the violence that rational persuasion might entail. (shrink)

This article explores the common points and the differences between Hans Kelsen’s and Robert Alexy’s application theories. Although Kelsen subscribed to moral relativism and denied the idea of a practical reason, while Alexy criticised moral relativism and defended the idea of a communicative reason, it is argued that the two theories share important common features, such as denying that interpretation can point one single answer as the right one and acknowledging that interpretation is comprised by both knowledge and will. The (...) article acknowledges that there are differences between both theories, analyses whether these differences are qualitative or quantitative and, in the end, concludes that between the two theories there is not disruption, as one might believe, but rather continuity.

Resumen: El presente trabajo analiza si los Sistemas de apoyo a la decisión (DSSs) y otros asistentes para su uso, como las Reflection machines o los Personal Assistants that Learn (PAL), contribuyen de hecho a una mejora cognitiva, como habitualmente se tiende a asumir. Es decir, se examina si su potencial para expandir e impulsar la acción de las facultades cognoscitivas se ve efectivamente actualizado y, en consecuencia, si sirven para reafirmar el sentido capacitante de la IA y la extensión (...) de la agencia del sujeto a través de ella. Para ello, se pone de manifiesto que el diseño y aplicación de estos sistemas están mediados por una comprensión del conocimiento que actúa a modo de marco que limita sus posibilidades de mejorar las capacidades cognoscitivas humanas. Se analizan las condiciones en que la mejora cognitiva es posible a través del uso de estos sistemas, que remiten a una aproximación integradora que no tiene en cuenta solo el factor tecnológico, sino que repara en cómo, en su uso, intervienen factores gnoseológicos, así como psicológicos y sociológicos, que median en la capacidad efectiva de estos sistemas de ampliar las facultades de conocimiento, y de los que las tecnologías se sirven para ejercer su influencia. Abstract: The present article questions whether Decision Support Systems (DSSs) and other assistants for their use, such as Reflection machines or Personal Assistants that Learn (PAL), do in fact contribute to cognitive enhancement, as it is usually taken for granted. In other words, it is analysed whether their potential to effectively expand or augment cognitive capacities is actualised and, therefore, if the capabilities and the agency of the person appear in fact extended through artificial intelligence. For that purpose, it is highlighted that the design and implementation of AI systems are dependent on a certain understanding of human knowledge that acts as a framework that limits their actual capacity to enhance the cognitive faculties of the mind. The conditions under which this cognitive enhancement is possible through these systems are analysed and require an integrative approach that not only takes technology into account but realises that, in its use, gnoseological, as well as psychological and sociological factors are involved and mediate in the actual capacity of these systems to extend cognitive functions. These factors are also crucial for these technologies to exert their influence. (shrink)

This text aims to rethink educational activity inspired by the thought of the philosopher Ignacio Ellacuría, in what we have synthesised as a pedagogy of poverty. This should be understood as a pedagogy that, in the neoliberal context of Western societies, takes poverty as its motor—its efficient cause—and as its essence or fundamental structure—its formal cause –, in the duality of dimensions of its genitive. It is concretised in what is presented as Problem-Based Service-Learning (PB-SL). Through specific pedagogical guidelines for (...) implementing this methodology, this study indicates how the teaching action can show the learner what is immediate, what is not constructed, what consciousness does not establish but rather encounters: reality—weak, limited, imperfect, needy; in short, poor—as a problem and, in its deficiency and insufficiency, as a task towards which the subject has a responsibility. This reveals the fundamental anthropological structure to the learner: its intrinsic relational character—its reality as a being-in-a-suffering-world, who lives-with and lives-to save the needy who share its humanity. It is then possible to perceive the scale of the ultimate aim of PB-SL: the need to create the social conditions for a praxis that enables a dignification of reality. (shrink)

Resumen La cuestión de la relación entre ciencia y fe ha adquirido nuevo vigor en los comienzos del siglo, cuando, tras años de especialización y separación fragmentaria de los saberes, que conducían a la esquizofrenia cultural del cognoscente, se empieza a percibir de manera cada vez más nítida la necesidad de su integración para dar cuenta de la multidimensionalidad de lo real. Tras poner de manifiesto la aparente tensión entre cultura y trascendencia como realidades que conviven en el ser humano, (...) se rastrea la posibilidad que Panikkar propone de una ciencia que, sin eliminarse a sí misma, sin cancelar la mediación que ella misma constituye ni despojarse de sus maneras y métodos propios, sin siquiera abandonar el plano de la pura inmanencia, reconoce en él lo divino: la infinita trascendencia del cuerpo -su carácter siempre abierto al misterio- y su infinita inmanencia -su profundidad insondable-. Esto tiene lugar en la forma concreta que el autor propone de una teofisica, de modo que con ella no ocurre algo semejante a lo que Wittgenstein indica respecto a la escalera de la que, una vez arriba -lograda la significación de lo Absoluto- puedo desprenderme, sino que, en ella, la escalera -la dimensión física- se conserva y se supera.The issue of the relationship between science and faith has acquired greater relevance since the beginning of the century, time in which, after years of specialization and fragmentation of human knowledge, which have led to a cultural schizophrenia of the knower, there is a growing awareness of the need to integrate both to account for a multidimensional reality. After noticing the apparent tension between culture and the divine as realities that coexist in human beings, it is examined Panikkar’s proposal of a science that, without eliminating itself, without cancelling the mediation that it constitutes, nor divesting itself from its own methods, not even without abandoning immanence, recognizes in itself the divine: the infinite transcendence of the body -its character always open to mystery- and its infinite immanence -its unfathomable depth-. This corresponds to the author’s theophysics, so that, in it, it does not happen something similar to what Wittgenstein indicates about the ladder of which one can get rid once up -when the significance of the divine has been attained-, but in it the ladder -the physical dimension- is preserved and surpassed.

Resumen El presente artículo plantea la necesidad de un acercamiento histórico a los textos filosóficos tomando como ejemplo el caso de la propuesta ética de David Hume. Se muestra el interés de Hume por insertarse en el diálogo intelectual de su época y su propósito de integrar el método científico en las ciencias morales y cómo la crítica que hace a la razón debe ser comprendida bajo esta luz. Para ello se menciona el ambiente intelectual de la época y las (...) posturas en conflicto en el debate filosófico del siglo XVIII: el escepticismo-relativista, el racionalismo exagerado y el sentimentalismo ingenuo, señalando que, en el fondo, Hume no puede ser excluido totalmente de ninguna de estas posturas pero tampoco encasillado en alguna de ellas.This article raises the need of a historical approach to philosophical texts taking as an example the case of David Hume’s ethics proposal. It shows Hume`s interest in participating actively in the intellectual dialogue of his time and his intention to integrate the scientific method into the moral sciences and how his critique of reason must be understood in this light. To do this, we quickly mention the intellectual atmosphere of the time and the positions in conflict in the philosophical debate of the 18th Century: relativistic skepticism, radical rationalism and naive sentimentality, noting that, deep down, Hume cannot be excluded completely from any of these positions but not typecast in any of them.

This book presents a conceptual mapping of supererogation in the analytic moral philosophical tradition. It first asks whether supererogation can be conceptualised in the absence of obligation or duty and then makes the case that it can be. It does so by enlisting the resources of the continental tradition, specifically using the work of Emmanuel Levinas and his notion of infinite responsibility. In so doing the book contributes to the ongoing efforts to create a common ethical terminology between the analytic (...) and continental traditions within moral philosophy. Supererogatory actions are praiseworthy actions that go ‘beyond duty’, and yet are not blameworthy when not performed. In responding to this paradox, moral philosophy either brackets or attempts a reductionism of supererogation. Supererogation is epitomised in the paradigmatic figures of the saint and hero. Yet, most would agree that emulating these figures is too morally demanding. We rightly ask: where does moral obligation end? Is it even possible, or desirable to demarcate such a boundary? Besides the important theoretical issues these questions raise, they also speak to practical ethical dilemmas in the contemporary milieu, as they concern the global wealthy’s responsibility to the poor and the challenges of development aid work.

En este artículo se expone una reflexión desde la propuesta teórica de Charles Taylor sobre la construcción de la identidad individual como una narración social frente a la crítica de Amartya Sen, quien propone la identidad como resultado solo de la elección personal. Se argumenta que las criticas que Amartya Sen hace a los argumentos de Taylor son infundadas, ya que la perspectiva de Charles Taylor se centra más en el carácter fundamentalmente constructivo, narrativo y dialógico de la identidad que (...) en la pérdida de la libertad y la mera aceptación acrítica de la identidad asumida. Se concluye que la identidad como narración social desde la perspectiva teoría de Taylor sí da cabida a la capacidad de elegir de los individuos y a la consideración de las identidades múltiples y múltiples lealtades identitarias, pero se hace notar la importacia del contexto social y del grupo por encima de la elección personal en el momento en que una persona contruye su identidad, ya que les da valor a los bienes externos como la comunidad cultural y lingüística a la que la pertenece y que hacen posible la inteligibilidad y la narracción de lo que somos y de quiénes somos. This paper presents Charles Taylor's theoretical proposal of construction of identity confronted to the criticism of Amartya Sen who conceives identity as a result of personal choice. It is argued that the critiques that Amartya Sen makes to the arguments of Taylor are groundless given that the perspective of Charles Taylor focuses more on the fundamentally constructive nature of identity than on the loss of freedom and the mere uncritical acceptance of the assumed identity. Taylor's theory does has space for the ability to choose and the consideration of multiple identities but it draws attention to the importance of social and group context when a person builds his identity and it assigns a higher value to the external goods that define the way people live in contemporary societies, such as the cultural and linguistic community, than to personal choice.

This study integrates corpus-assisted text analysis with frame semantics to study a social problem. Taking a cognitive-linguistic approach to critical discourse studies, in this article I examine the linguistic construction of minors in a corpus of 489 articles from the Uruguayan newspaper El País in the context of the so-called ‘Criminal Imputability Referendum’. Throughout, I focus on the construal operation of framing and identify a host of discursive patterns via which minors and adolescents are recurrently placed within the semantic frame (...) CRIME, and within this, they profile the frame elements of perpetrators of violent crimes rather than victims. I argue that, in the context of the referendum, these discursive strategies run the risk of facilitating the consolidation of a strong conceptual link whereby youth become readily associated with criminality, and are subservient to the political views of groups supporting a lower cut-off age for criminal responsibility and more stringent punishments. The observations arrived at in this instance set the foundations for a future experimental study testing whether the discursive patterns unearthed here have an effect on how readers conceptualize minors outside the texts.

O objetivo deste texto é examinar aspectos da filosofia de Merleau-Ponty considerando-a distante tanto de um subjetivismo fenomenológico, quanto de um objetivismo estruturalista, posições descritas por Michel Foucault como determinantes do debate filosófico francês dos anos 1950. Um caminho possível para descrever sua posição é investigar a maneira como trabalha o tema da linguagem, tanto a partir de sua apropriação da linguística de Saussure, quanto em interlocução com as reflexões de Bergson - ponto pouco explorado entre os intérpretes. Também em (...) relação a Bergson, discutirei a concepção de temporalidade presente em Merleau-Ponty, distanciando-a, ao mesmo tempo, da maneira como Sartre a compreende. Ao final desse trajeto, penso que se tornará mais clara a proposta merleau-pontyana de uma fenomenologia alargada e dialógica. (shrink)

El texto reflexiona sobre el vaciamiento neoliberal de la política, despolitizando la vida y cuantificando la realidad. El neoliberalismo enaltece la libertad individual, llevando a un individualismo extremo que amenaza el tejido social. La destrucción creativa moldea cuerpos y subjetividades, promoviendo competencia y autosacrificio. La exterioridad neoliberal afecta a los individuos, enfocándolos en su propia libertad y bloqueando su capacidad de actuar con otros. La crítica se centra en recuperar la sensibilidad y el deseo para restaurar la vida colectiva, explorando (...) la relación entre el cuerpo entristecido y la lógica neoliberal de acumulación y autorresponsabilidad, sugiriendo que puede generar cuerpos tristes y descontentos -todo esto en atención a una ontología spinozista-. Se critica, así, el culto a la vida en la sociedad neoliberal y cómo se marginaliza a los cuerpos vulnerables, abogando por abrazar la vulnerabilidad y la interdependencia para superar la lógica destructiva y la obsesión por la acumulación.

Este artículo esboza una respuesta a la pregunta sobre cómo explicar los efectos de las tecnologías en la sociedad. Su propósito es mostrar una alternativa a los tradicionales discursos deterministas, los cuales suponen que las tecnologías impactan las formas de organización social. A partir de una crítica a las explicaciones deterministas que predominan actualmente, se presenta una primera conclusión: no hay una relación clara entre los cambios sociales y las características técnicas de las tecnologías. Así, se argu¬menta que las tecnologías (...) no causan impactos, sino que los cambios sociales son productos de procesos de interpretación, negociación y materialización de los intereses de los actores involucrados. De esta forma, los artefactos tecnológicos se asumen como agentes del cambio, pero no por una esencia técnica, sino por el papel que desempeñan, el cual resulta definido en el proceso de significación del artefacto a medida que es vinculado a la red, es decir, en la construcción del cambio.

Great progress to digitize the world’s available Biodiversity and Biogeography data have been made recently, but managing data from many different providers and research domains still remains a challenge. A review of the current landscape of metadata standards and ontologies in Biodiversity sciences suggests that existing standards, such as the Darwin Core terminology, are inadequate for describing Biodiversity data in a semantically meaningful and computationally useful way. As a contribution to fill this gap, we present an ontology-based system, called BiGe-Onto, (...) designed to manage data together from Biodiversity and Biogeography. As data sources, we use two internationally recognized repositories: the Global Biodiversity Information Facility and the Ocean Biogeographic Information System. BiGe-Onto system is composed of BiGe-Onto Architecture a conceptual model called BiGe-Onto specified in OntoUML, an operational version of BiGe-Onto encoded in OWL 2, and an integrated dataset for its exploitation through a SPARQL endpoint. We will show use cases that allow researchers to answer questions that manage information from both domains. (shrink)

This paper addresses Hannah Arendt’s approach in “Truth and Politics” to the use of lies in the public and political spheres. Considering Derrida’s review in his lecture History of the Lie: Prolegomena, we will attempt to resolve questions of greater importance: How can a lie be politically effective? What does that efficiency imply? We will see that in politics lies do not consist, as Arendt and her tradition have argued, in the intentionality of the message or in self-deception ; but (...) rather that lying produces “effects of truth”, generating, producing and sustaining new truths and realities by virtue of the speech acts themselves. However, just as not every performative utterance is mendacious, we will also see in what sense the effectiveness of the political lie is deeply related to who is the agent of that saying. (shrink)
