El presente trabajo elucida el axioma de “la pluralidad necesaria” a partir de algunas calas y notas del pensamiento de Judith Butler y algunos cruces procedentes de la filosofía de Michel Foucault y Friedrich Nietzsche, así como el influjo postnietzscheano contemporáneo, en contraste con el pensamiento mestizo subalterno latinoamericano de Gloria Anzaldúa. La hipótesis central es explicada en estos términos: no existe ningún fundamento metafísico que sustente al mundo; todo es una construcción cultural, resultado del poder predominante en un determinado (...) contexto histórico. El poder es el que establece lo que es normal o anormal, lo que está permitido o no está permitido. En este contexto, se postula la necesidad de someter a los dispositivos de poder reinantes, en las sociedades contemporáneas, bajo una revisión crítica que permita transformarlos en dispositivos de poder que hagan posible sociedades plurales e incluyentes. Y justo aquí, en la apertura de un nuevo horizonte postmetafísico y post-humanista es retomada la perspectiva mestiza subalterna de Gloria Anzaldúa como una forma radical de repensar la condición humana más allá del euro-logo-falocéntrismo desde los márgenes de América Latina. La pluralidad necesaria, lejos de ser un título contradictorio, es, antes bien, un título que expresa una afirmación, a saber, la necesidad de una realidad social plural, inclusiva, en la que las diferencias entre los seres humanos sean respetadas, siguiendo el ideal de una sociedad democrática en la que se cultive la apertura a los otros, en un ambiente de convivencia y diálogo.

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)

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.

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)

The first clear and precise statement of the axioms of qualitative probability was given by de Finetti ([1], Section 13). A more detailed treatment, based however on more complex axioms for conditional qualitative probability, was given later by Koopman [5]. De Finetti and Koopman derived a probability measure from a qualitative probability under the assumption that, for any integer n, there are n mutually exclusive, equally probable events. L. J. Savage [6] has shown that this strong assumption is unnecessary. More (...) precisely, he proves that if a qualitative probability is only fine and tight, then there is one and only one probability measure compatible with it. No property equivalent to countable additivity has been used as yet in the development of qualitative probability theory. However, since the concept of countable additivity is of such fundamental importance in measure theory, it is to be expected that an equivalent property would be of interest in qualitative probability theory, and that in particular it would simplify the proof of the existence of compatible probability measures. Such a property is introduced in this paper, under the name of monotone continuity. It is shown that, if a qualitative probability is atomless and monotonely continuous, then there is one and only one probability measure compatible with it, and this probability measure is countably additive. It is also proved that any fine and tight qualitative probability can be extended to a monotonely continuous qualitative probability, and therefore, contrary to what might be expected, there is no loss in generality if we consider only qualitative probabilities which are monotonely continuous. At the present time there is still a controversy over the interpretation which should be given to the word probability in the scientific and technical literature. Although the present writer subscribes to the opinion that this interpretation may be different in different contexts, in this paper we do not enter into this controversy. We simply remark that a qualitative probability, as a numerical one, may be interpreted either as an objective or as a subjective probability, and therefore the following axiomatic theory is compatible with both interpretations of probability.

The CRISPR system for gene editing can break, repair, and replace targeted sections of DNA. Although CRISPR gene editing has important therapeutic potential, it raises several ethical concerns. Some bioethicists worry CRISPR is a prelude to a dystopian future, while others maintain it should not be feared because it is analogous to past biotechnologies. In the scientific literature, CRISPR is often discussed as a revolutionary technology. In this paper we unpack the framing of CRISPR as a revolutionary technology and contrast (...) it with framing it as a value-threatening biotechnology or business-as-usual. By drawing on a comparison between CRISPR and the Ford Model T, we argue CRISPR is revolutionary as a product, process, and as a force for social change. This characterization of CRISPR offers important conceptual clarity to the existing debates surrounding CRISPR. In particular, conceptualizing CRISPR as a revolutionary technology structures regulatory goals with respect to this new technology. Revolutionary technologies have characteristic patterns of implementation, entrenchment, and social impact. As such, early identification of technologies as revolutionary may help construct more nuanced and effective ethical frameworks for public policy. (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)

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)

La mirada del envejecimiento, desde una visión de derechos, tiene como antecedente la Segunda Asamblea Mundial sobre Envejecimiento, de la cual se derivó el Plan Internacional de Acción en Envejecimiento de Madrid, que ha sido un documento clave de seguimiento en las reuniones regionales intergubernamentales y no gubernamentales sobre envejecimiento en la región latinoamericana. Adicionalmente, existen dos instrumentos claves a considerar en las políticas de envejecimiento de la región: el Consenso de Montevideo y la Convención Interamericana para la Protección de (...) los Derechos de las Personas Mayores. En todos estos documentos, se abordan las siguientes áreas prioritarias: la situación económica de las personas mayores; salud y bienestar; y entornos sociales y físicos favorables. En este artículo, se analiza cómo ha sido el tratamiento, en las distintas reuniones regionales, del tema de cuidados, el cual se inserta en el área sobre salud y bienestar, además de discutir cómo se han traducido los distintos señalamientos sobre cuidados en la normativa de México.

En la vida cotidiana del ejercicio del derecho, ya sea en el campo de la judicatura, ora en el del litigio, bien sea en el de la academia, o en actividades administrativas, es bastante común que se hable de la prueba sumaria; pero desafortunadamente no es común que se tenga plena conciencia de su entidad, alcances y usos conforme a su propia naturaleza. Es preocupante observar la peligrosa y antijurídica ligereza, con la cual se acude a la prueba sumaria; pero (...) no para darle su natural uso, sino para superar omisiones de los sujetos procesales con interés de parte en el cumplimiento de las cargas probatorias. La prueba sumaria es utilizada en forma deliberada para conseguir ciertas ventajas probatorias en el proceso, con evidente desmedro del derecho de prueba de la contraparte, afectación de la garantía de la igualdad real de las partes en el proceso, y conculcación del derecho de defensa en toda su extensión. En realidad, el mal uso de la prueba sumaria implica violar los principios probatorios de necesidad, publicidad, contradicción, legalidad y formalidad de la prueba. En otros términos, la utilización indiscriminada de la prueba sumaria, sin el cuidado y la estrictez exigidos expresamente por el mismo legislador para poder usarla, constituye una manifiesta violación al derecho constitucional fundamental al debido proceso.

This article describes four doctoral students' process of coming together to support each other's work. What emerged was a powerful space of learning and a framework on research for social change. The authors hosted a 2-hour reflection session, which was recorded and transcribed. Text of that session appears in this article along with discussion of (a) key principles of the social change framework, (b) the ways the students came to take ownership over their work and to collaborate, and (c) guidance (...) for other researchers working against the isolation and competition that is too common in the academy.

A number of biologists and philosophers have noted the diversity of interpretations of evolvability in contemporary evolutionary research. Different clusters of research defined by co-citation patterns or shared methodological orientation sometimes concentrate on distinct conceptions of evolvability. We examine five different activities where the notion of evolvability plays conceptual roles in evolutionary biological investigation: setting a research agenda, characterization, explanation, prediction, and control. Our analysis of representative examples demonstrates how different conceptual roles of evolvability are quasi-independent and yet exhibit important (...) relationships across scientific activities. It also provides us with the resources to detail two distinct strategies for how evolvability can help to synthesize disparate areas of research and thereby potentially serve as a unifying concept in evolutionary biology.

This paper investigates how the introduction of AI to decision making increases moral distance and recommends the ethics of care to augment the ethical examination of AI decision making. With AI decision making, face-to-face interactions are minimized, and decisions are part of a more opaque process that humans do not always understand. Within decision-making research, the concept of moral distance is used to explain why individuals behave unethically towards those who are not seen. Moral distance abstracts those who are impacted (...) by the decision and leads to less ethical decisions. The goal of this paper is to identify and analyze the moral distance created by AI through both proximity distance (in space, time, and culture) and bureaucratic distance (derived from hierarchy, complex processes, and principlism). We then propose the ethics of care as a moral framework to analyze the moral implications of AI. The ethics of care brings to the forefront circumstances and context, interdependence, and vulnerability in analyzing algorithmic decision making. (shrink)

En este artículo, se analiza la documentación producida por autores franceses o afrancesados, en la cual América y sus procesos de independencia, en particular los hispanoamericanos, ocupan un lugar central. Se localiza un importante corpus documental que incluye libros e impresos periódicos. Algunos de ellos fueron de uso en las escuelas primarias y secundarias francesas, otros circularon entre académicos y profesores universitarios. También se analizan algunos textos provenientes de conmemoraciones americanistas, como discursos de legatarios o personalidades con prestigio político o (...) científico, y textos literarios que concursaron en variados eventos vinculados con las celebraciones y conmemoraciones de la Independencia. A partir de ellos, se proponen cinco ejes de reflexión: primero, desde la perspectiva de las representaciones sociales, políticas y culturales de las independencias hispanoamericanas, donde las preocupaciones investigativas están orientadas a lo que se dice que pasó y menos a lo que pasó. Segundo, la reiteración de la categoría influencia para pensar las relaciones decimonónicas entre América y Francia subraya la originalidad de las ideas ilustradas y la Revolución Francesa; en cambio, las revoluciones hispanoamericanas representarían una de sus consecuencias más o menos distorsionada a este lado del Atlántico. Tercero, el lenguaje hermenéutico de lo que se dice que pasó instituyó mitos políticos modernos, asociados directamente con una revolución exitosa, igualitaria, libertaria y fraterna. Cuarto, en el contexto planetario de las dinámicas de modernización política, “lo francés” debe ser pensado como una parte de los procesos de mundialización de la modernidad. Quinto, el examen social y cultural de la producción intelectual presentada permite una mirada crítica a las historias nacionales o continentales, de tal forma que se puedan comprender mejor los procesos de modernización.

The origin of Being as a live concept is one of the most difficult questions in history of metaphysics and ontology. This work analyses the postulate that being is constructed by the interaction of terms. In fact, being and the idea of Being has come from the possibility of relations. It is known that metaphysics and ontology has overestimated think Being like something that never change, a substance unchangeable. Reduce Being as ousía, translated as substance, does not understand central affirmation (...) of Aristotle that “The term “being” is used in various senses, but with reference to one central idea and one definite characteristic, and not as merely a common epithet.”. The usually interpretation of relations make them one of those ways, however the concept of Being is always under a relation. Is reconsidered the role of relations in the basis of ontological thinking, taking the renewal of metaphysics, of the French philosopher Jean Wahl, and postulating that Being as totality is the relation that involves beings, Change and Time.

The Hoffmann reflex (H-wave) is produced by alpha-motoneuron activation in the spinal cord. A feature of this electromyography response is that it exhibits fluctuations in amplitude even during repetitive stimulation with the same intensity of current. We herein explore the hypothesis that physical training induces plastic changes in the motor system. Such changes are evaluated with the fractal dimension (FD) analysis of the H-wave amplitude-fluctuations (H-wave FD) and the cross-covariance (CCV) between the bilateral H-wave amplitudes. The aim of this study (...) was to compare the H-wave FD as well as the CCV before and after track training in sedentary individuals and athletes. The training modality in all subjects consisted of running three times per week (for 13 weeks) in a concrete road of 5 km. Given the different physical condition of sedentary vs. athletes, the running time between sedentary and athletes was different. After training, the FD was significantly increased in sedentary individuals but significantly reduced in athletes, although there were no changes in spinal excitability in either group of subjects. Moreover, the CCV between bilateral H-waves exhibited a significant increase in athletes but not in sedentary individuals. These differential changes in the FD and CCV indicate that the plastic changes in the complexity of the H-wave amplitude fluctuations as well as the synaptic inputs to the Ia-motoneuron systems of both legs were correlated to the previous fitness history of the subjects. Furthermore, these findings demonstrate that the FD and CCV can be employed as indexes to study plastic changes in the human motor system. (shrink)

This article is about specific uses of the thought of Spinoza, studied through a selection of books concerning personal development and philosophy of management. Through a discourse of truth and authority, these texts give rise to the formulation of a Spinozism that philosophically justifies the ideal types of neoliberalism and make Spinoza the father of this social, political, and economic model. Thus, the authors want to convince individuals that they must concentrate on their affects, by postulating that happiness and freedom (...) can only be achieved by working on oneself. However, this means minimising the influence of a social exteriority that remains crucial to Spinozian philosophy. This article studies what has been retained from the Spinozian corpus, to make it correspond to neoliberalism and to apply these practices of personal development and philosophy of management. We also point out the limits of this singular interpretation of Spinoza, while questioning the relevance of this type of adaptation of his philosophy to contemporary times. (shrink)
