En el curso dictado en Collège de France sobre la institución y la pasividad, Merleau-Ponty le otorgó una importancia particular a las problemáticas freudianas. La sexualidad y muy especialmente el Complejo de Edipo, es presentado como ejemplo de la institución humana en un doble sentido: en cuanto clase de institución que se diferencia de la institución vital y como una institución antropomórfica. Sus momentos –sexualidad prepuberal, periodo de latencia, pubertad– ejemplifican la estructura de toda institución: la anticipación, el desvío y (...) la reanudación y ponen de manifiesto su temporalidad propia. En vistas a la importancia del Complejo de Edipo en la arquitectura general del curso, el presente trabajo tiene por objetivo reponer la interpretación realizada por Merleau-Ponty a los efectos de comprender la especificidad de la institución humana. De este modo, se pretende realizar una aproximación al vínculo entre temporalidad e institución tal como Merleau-Ponty lo considera en el curso en cuestión.In the course dictated in Collège de France on the institution and the passiveness, Merleau-Ponty granted a particular importance to the Freudian problematics. The sexuality and very specially the Complex of Oedipus, is presented as example of the human institution in a double meaning: regarding a type of institution that differs from the vital institution and as an anthropomorphic institution. Its moments – prepuberal sexuality, period of latency, puberty –exemplify the structure of any institution: the anticipation, the detour and the resumption and they reveal his own temporality. In conference to the importance of the Complex of Oedipus in the general architecture of the course, the present work has for aim re-put the interpretation realized by Merleau-Ponty to the effects of understanding the specificity of the human institution. Thus, one tries to realize an approximation to the link between temporality and institution as Merleau-Ponty considers it in the course in question. (shrink)

The "people of knowledge" of traditional Mazatec medicine have preserved until today the ritual use of psilocybin mushrooms as part of their health care systems. The renewed interest in the effect of psilocybin on human consciousness for both therapeutic and recreational purposes usually obviates the historical and cultural background of indigenous peoples, as well as the legitimation of their practices and knowledge. In this article, through the case study of a foreign person who attended a Mazatec ritual specialist to participate (...) in a ritual night ceremony known as velada, we show the importance of approaching research on psychoactive plants and mushrooms from a transdisciplinary and intercultural perspective, so that we can appreciate the profound complexity of the healing processes that take place in traditional indigenous contexts, as well as the limits of recreational uses or exclusively neopositivist and clinical approaches.

Este artículo examina en clave de resiliencia la historia del protagonista de la obra mencionada de C.S. Lewis. Sus experiencias de vida muestran las muchas maneras en las que una persona puede experimentar un cambio radical y tener una actitud resiliente. Los objetivos de nuestro análisis literario son varios. Definir y actualizar el concepto de resiliencia, poner de relieve el funcionamiento de la teoría aristotélica de la mímesis y la metanoia, y analizar el proceso resiliente del protagonista literario. Con todo, (...) se llega a la conclusión de que la novela constituye un paradigmático ejemplo de historia y personaje resilientes. (shrink)

In this commentary to Leal (2013), we argue that the memorization of the names and symbols of the chemical elements is necessary in the study of that topic because this task is the key for the later understanding of the Periodic Table. We can make the memorization task in an enjoyable, but effective way, using some educational games in chemistry class. Some recent puzzles, card games, mnemonics rules or games based on drawings to learn the chemical elements are addressed in (...) this paper. (shrink)

Neste artigo apresento como objetivo a divulgação de um conjunto de debates que se cruzam nos feminismos, evidenciando, neste caso, a multiplicidade de formas de entender o feminismo e o ser feminista. Parto da ideia de um mundo em transformação pautado em um contexto de rupturas de pensamentos e modelos universais. Sendo assim, quatro críticas ao movimento feminista são apresentadas em diálogo com uma autocrítica que transforma o feminismo universal em feminismos múltiplos, com características mais humanas, de equidade e de (...) inclusão. Por fim, o texto leva a crer na importância do reconhecimento do lugar de fala para todas as pessoas, diferenciando-se em lugares de falas de privilégios ou lugares de falas marginalizados, sendo que tais lugares são flexíveis a partir da espacialidade e das identidades.

Soberanía y obediencia fueron dos nociones clave en las discusiones que se dieron en los albores de la modernidad. Parte de los debates se centró en la cuestión de la legitimidad del poder político y, en consecuencia, en por qué debemos obedecer, qué beneficios trae la obediencia y cuáles son sus límites. En todos estos casos, la noción de violencia aparece con diferentes rostros, y principalmente con la fisonomía de la guerra —punto de máxima expresión de la violencia explícita—, problema (...) que la autoridad política viene, de alguna manera, a resolver. El Estado soberano, sin embargo, lejos está de ser la representación del irenismo, se convierte en monopolio legítimo de la violencia. Este trabajo pretende abordar tales cuestiones desde las teorías de Hobbes y Harrington. Ambos justificaron la obligación de los súbditos a acatar la ley que se impone y que garantiza, por sobre todas las cosas, su vida. (shrink)

Queen pheromones, which signal the presence of a fertile queen and induce daughter workers to remain sterile, are considered to play a key role in regulating the reproductive division of labor of insect societies. Although queen pheromones were long thought to be highly taxon‐specific, recent studies have shown that structurally related long‐chain hydrocarbons act as conserved queen signals across several independently evolved lineages of social insects. These results imply that social insect queen pheromones are very ancient and likely derived from (...) an ancestral signalling system that was already present in their common solitary ancestors. Based on these new insights, we here review the literature and speculate on what signal precursors social insect queen pheromones may have evolved from. Furthermore, we provide compelling evidence that these pheromones should best be seen as honest signals of fertility as opposed to suppressive agents that chemically sterilize the workers against their own best interests.

A noção de intensidade é de extrema importância para o pensamento deleuziano, fazendo-se presente não apenas na elaboração de sua própria filosofia da diferença, como também nas leituras que faz dos outros filósofos que lhe são caros, especialmente na sua reconstrução do espinosismo. Deleuze concebe a essência singular espinosana em termos intensivos. Sendo assim, este artigo procura reunir elementos para mostrar a importância da noção de intensidade no projeto deleuziano de unificação dos dois sentidos de estética e o papel do (...) uso de concepções de extração espinosista na empresa deleuziana. Estes apontamentos deixam implícito um outro tema: o da possibilidade de elaborar uma Estética a partir de Espinosa, vale dizer, uma Estética atenta a sua ancoragem corporal. (shrink)

O texto aproxima certas concepções de Deleuze e Guatarri relativas ao que poderíamos aqui chamar provisoriamente de uma “teoria do desejo”, tal como esboçada no Anti-Édipo, da teoria dos afetos formulada na Ética de Espinosa, mostrando assim mais uma etapa da crítica da tradição psicanalítica na obra conjunta dos filósofos franceses.

To date, no definition of life has been unequivocally accepted by the scientific community. In frustration, some authors advocate alternatives to standard definitions. These include using a list of characteristic features, focusing on life’s effects, or categorizing biospheres rather than life itself; treating life as a fuzzy category, a process or a cluster of contingent properties; or advocating a ‘wait-and-see’ approach until other examples of life are created or discovered. But these skeptical, operational, and pluralistic approaches have intensified the debate, (...) rather than settled it. Given the failure of even these approaches, we advocate a new strategy. In this paper, we reverse the usual line of reasoning and argue that the “life problem” arises from thinking incorrectly about the nature of life. Scientists most often conceptualize life as a class or kind, with earthly life as a single instance of it. Instead, we advocate thinking about Earth’s Life as an individual, in the way that species are now thought to be. In this view, Life is a monophyletic clade that originated with a last universal common ancestor, and includes all its descendants. We can continue to use the category ‘life’ pragmatically to refer to similarities between various phenomena and Life. But the relevant similarities are a matter of interest and preference, not a matter of fact. The search for other life in the Universe, then, is merely a search for entities that resemble parts of Life in whatever sense astrobiologists find most appealing. This does not mean that the search for evolved complexity elsewhere in the universe or its creation in the lab are futile endeavors, but that debates over whether they count as ‘life’ are. Ironically, finally abandoning the concept ‘life’ may make our searches for evolved complexity more fruitful. We explain why. (shrink)

O texto investiga a dança como modalidade de produção de subjetividades privilegiada para dar a ver a potência do corpo. Procura equacionar o problema da sobrevivência de um vocabulário mental para tratar daquilo que exprime com a máxima intensidade aquilo de que os corpos são capazes, a saber, os corpos dançantes. Esta pesquisa segue uma trilha espinosista, para encontrar um vocabulário inteiramente corporal para descrever a potência dos corpos na dança em termos inteiramente corporais.

Stephen Jay Gould argued that replaying the ‘tape of life’ would result in radically different evolutionary outcomes. Recently, biologists and philosophers of science have paid increasing attention to the theoretical importance of convergent evolution—the independent origination of similar biological forms and functions—which many interpret as evidence against Gould’s thesis. In this paper, we examine the evidentiary relevance of convergent evolution for the radical contingency debate. We show that under the right conditions, episodes of convergent evolution can constitute valid natural experiments (...) that support inferences regarding the deep counterfactual stability of macroevolutionary outcomes. However, we argue that proponents of convergence have problematically lumped causally heterogeneous phenomena into a single evidentiary basket, in effect treating all convergent events as if they are of equivalent theoretical import. As a result, the ‘critique from convergent evolution’ fails to engage with key claims of the radical contingency thesis. To remedy this, we develop ways to break down the heterogeneous set of convergent events based on the nature of the generalizations they support. Adopting this more nuanced approach to convergent evolution allows us to differentiate iterated evolutionary outcomes that are probably common among alternative evolutionary histories and subject to law-like generalizations, from those that do little to undermine and may even support, the Gouldian view of life.

En el canto V del infierno de la Divina Comedia, el autor presenta diferentes ejemplos de condenados por la lujuria. En este trabajo se propone la clasificación de dichos personajes en dos categorías, por un lado, aquellos que someten la razón a la pasión erótica y, por el otro, aquellos que la someten a la pasión afectiva. Así mismo, se cuestionan los motivos por los cuales el autor florentino considera estas aproximaciones como transgresiones graves contra «el orden del amor». A (...) continuación, se lleva a cabo un análisis comparativo de estos dos tipos de amor presentes en dos obras que establecen una clara relación de intertextualidad con la Divina Comedia, a saber, la No-Divina Comedia de Zygmunt Krasinski y Don Juan en el infierno de Carlos Fisas. Se demuestra de este modo la amplitud de la influencia de este autor en diferentes épocas y espacios culturales, así como, su asombrosa universalidad. (shrink)

Our understanding of the universe has grown rapidly in recent decades. We’ve discovered evidence of water in nearby planets, discovered planets outside our solar system, mapped the genomes of thousands of organisms, and probed the very origins and limits of life. The scientific perspective of life-as-it-could-be has expanded in part by research in astrobiology, synthetic biology, and artificial life. In the face of such scientific developments, we argue there is an ever-growing need for universal biology, life-as-it-must-be, the multidisciplinary study of (...) non-contingent aspects of life as guided by biological theory and constrained by the universe. We present three distinct but connected ways of universalizing biology—with respect to characterizing aspects of life everywhere, with respect to the explanatory scope of biological theory, and with respect to extending biological insights to the structure of nonbiological entities. For each of these, we sketch the theoretical goals and challenges, as well as give examples of current research that might be labeled universal biology. (shrink)

En este artículo, ofreceremos algunas reflexiones sobre la historia en la obra de Hannah Arendt partiendo de la premisa de que esta se asienta en su concepto de acción. Con tal fin, recurriremos a distintos textos en los que la autora alemana discutió nociones cruciales para su definición de la condición humana, a saber, las tres actividades bajo las cuales se le dio vida al hombre en la Tierra –labor, trabajo y acción– y la separación entre lo público y lo (...) privado. Nuestro vínculo con el pasado y su relación tanto con el presente como con el futuro estarán también en el centro del recorrido que aquí proponemos. (shrink)

Is it possible to know anything about life we have not yet encountered? We know of only one example of life: our own. Given this, many scientists are inclined to doubt that any principles of Earth’s biology will generalize to other worlds in which life might exist. Let’s call this the “N = 1 problem.” By comparison, we expect the principles of geometry, mechanics, and chemistry would generalize. Interestingly, each of these has predictable consequences when applied to biology. The surface-to-volume (...) property of geometry, for example, limits the size of unassisted cells in a given medium. This effect is real, precise, universal, and predictive. Furthermore, there are basic problems all life must solve if it is to persist, such as resistance to radiation, faithful inheritance, and energy regulation. If these universal problems have a limited set of possible solutions, some common outcomes must consistently emerge. In this chapter, I discuss the N = 1 problem, its implications, and my response (Mariscal 2014). I hold that our current knowledge of biology can justify believing certain generalizations as holding for life anywhere. Life on Earth may be our only example of life, but this is only a reason to be cautious in our approach to life in the universe, not a reason to give up altogether. In my account, a candidate biological generalization is assessed by the assumptions it makes. A claim is accepted only if its justification includes principles of evolution, but no contingent facts of life on Earth. (shrink)

“¿Cómo habría vivido el género humano si Adán no hubiera pecado?”. Este es el tema desarrollado por Francisco Suárez en el quinto libro del Tractatus de opere sex dierum. Según el pensamiento del Doctor Eximius, la pregunta encierra en sí misma la solución, o sea, que el arquetipo Adán y el hombre inmerso en el tiempo no difieren entre ellos y que, como directa consecuencia, para ambos, agregarse a otros semejantes, permite que cada individuo alcance una finalidad y una mayor (...) perfección. El hombre arquetipal no es único sino múltiple y, en su multiplicidad, se diferencia, lo mismo que ocurre con el hombre pre-caída. Francisco Suárez, por eso, analiza tanto el antecedente teológico, según el acto creacional divino, como el fundamento político de la comunidad humana, consecuencia necesaria para el hombre formado de tal manera.

This book focuses on the emerging scientific discipline of astrobiology, exploring the humanistic issues of this multidisciplinary field. To be sure, there are myriad scientific questions that astrobiologists have only begun to address. However, this is not a purely scientific enterprise. More research on the broader social and conceptual aspects of astrobiology is needed. Just what are our ethical obligations toward different sorts of alien life? Should we attempt to communicate with life beyond our planet? What is “life” in the (...) most general sense? The current volume addresses these questions by looking at different perspectives from philosophers, historians, theologians, social scientists, and legal scholars. It sets a benchmark for future work in astrobiology, giving readers the groundwork from which to base the continuous scholarship coming from this ever-growing scientific field. (shrink)
