En los últimos años, algunos autores han venido sosteniendo que la validez de la representación arborescente del patrón filético generado por la evolución está siendo menoscabada por el reconocimiento del impacto evolutivo que tendrían la transferencia genética horizontal, la simbiogénesis, la especiación por hibridación y la introgresión. Esa concepción o representación cladogenética de la evolución sólo nos dejaría ver un aspecto parcial de las relaciones de filiación que conectan a los diferentes linajes de seres vivos; ocultando otro aspecto cuya representación (...) más adecuada sería un reticulado de relaciones entre taxones. Con todo, aún sin poner en tela de juicio la frecuencia y la relevancia explicativa de dichos fenómenos, en este trabajo se intentará mostrar que su admisión y reconocimiento no tiene por qué ir en detrimento de esa concepción cladogenética de la evolución cuya relativización se está pregonando. Por el contrario, la comprensión y la representación de tales fenómenos supone dicha concepción. Palabras clave: Filogénesis, Especiación por hibridación, Introgresión, Simbiogénesis, TGH. (shrink)

On cherche ici à penser, à travers les pages du livre d' André Neher, L'Exil de la parole. Du silence biblique au silence d'Auschwitz, ce qui, dans une expression fort rhétorique, se dit comme « la défaite de Dieu ». Il s'agit de tenter, une nouvelle fois, de comprendre cette défaite du Dieu biblique face à la Catastrophe : de sonder les modulations ou les variations de Son éclipse. À travers l'herméneutique du nom biblique « Shadday » attribué à Dieu, (...) on cherche à évaluer les limites de la puissance divine. Mais c'est peut-être dans le ve hen lâ et le Kouléhay ve-oulay! qu'il faut chercher les derniers et les premiers mots d'une foi née ex nihilo. The attempt here is to understand, through the pages of André Neher's book, L'Exil de la parole. Du silence biblique au silence d'Auschwitz - translated into English: The Exile of the Word: from the Silence of the Bible to the Silence of Auschwitz — what is defined in the highly rhetorical phrase of « God's defeat ». It is once again an effort to comprehend this defeat of the biblical God in the face of the Shoah, and to probe the modulations or the variations of His eclipse. Reviewing the hermeneutics of the biblical name "Shadday" assigned to God, this paper tries to evaluate the limits of God's divine power. It may well be in the ve hen la and the Kouléhay ve-oulayl that one must look for the last and the first words of a faith born ex nihilo. (shrink)

El objetivo de este trabajo es poner al descubierto los principales valores cognitivos y epistemológicos desde los que Warren Weaver puso en marcha el Programa de Biología Experimental, un programa que llevado a cabo desde la presidencia de la división de ciencias naturales de la Fundación Rockefeller, marcó y condicionó en buena medida el posterior desarrollo de la investigación biológica. Para tal fin se mostrará, en primer lugar, cómo fue la llegada de Weaver a la Fundación Rockefeller, así como las (...) razones bajo las cuáles el consejo de esa institución decidió entre 1932 y 1933 dar prioridad a las investigaciones biomédicas, y la manera por la cual lo hicieron. En un segundo momento, el más extenso e importante, veremos algunos de los elementos más significativos de la perspectiva epistemológica y cognoscitiva de de Weaver. Finalizaremos viendo cómo esa perspectiva, desarrollada en conexión con el Programa de Biología Experimental, inter-actuó con la visión reduccionista de la biología a la que el programa parecía apuntar. The aim of this article is to uncover the main cognitive and epistemological values that influenced Warren Weaver in starting the Experimental Biology Program, a program carried out from the time that he became president of the Natural Sciences Division of the Rockefeller Foundation, and which significantly marked and conditioned the subsequent development of biological research. To this end, we first describe the arrival of Warren Weaver at the Rockefeller Foundation, and the reasons for which the Board of this Foundation, between 1932 and 1933, decided to prioritize biomedical research, and the manner in which they did so. Then, secondly, in the largest and most important part of the article, we will present some of the most significant elements of Weaver's epistemological and cognitive perspective. Finally, we will show how this perspective, developed in connection with the Experimental Biology Program, interacted with the reductionist view of biology to which the program seemed to point.

The Darwinian revolution supposed and imposed a much broader and more complex concept of environment than that which, until that moment, had been considered by most as part of natural history. Until Darwin, the environment of living beings had been regarded, almost exclusively, as the inanimate surroundings. This pre-Darwinian notion of environment included physicochemical and climatic variables: the living beings themselves were scarcely considered, or they were regarded just as food to be assimilated. In contrast, with Darwin, the influence of (...) living surroundings began to be regarded as having decisive importance for understanding the distribution, configuration, and viability of living beings. The relationships established among different living beings became the main and more significant features of the biological environment. This conceptual change was an exigency derived from the formulation and justification of the theory of natural selection. The idea of struggle for existence supposed by that theory requires that the biotic environment be considered critical in determining the viability of each living being. (shrink)

En la Teoría de la Selección Natural, el concepto de función biológica debe suponerse para delimitar el concepto de aptitud; y éste debe suponerse para delimitar el concepto de adaptación y también para explicar el fenómeno al que este último alude. Esos tres conceptos, por otra parte, son especificaciones de tres conceptos de aplicación más universal. El concepto de función biológica es un caso particular del concepto general de función; y el concepto de aptitud especifica el concepto de eficiencia. El (...) concepto de adaptación, mientras tanto, es una especificación del concepto de diseño. La visualización de esas articulaciones conceptuales permite entender la legitimidad de la naturalización de la teleología operada por el darwinismo.In Natural Selection Theory, the concept of biological function must be supposed to elucidate the concept of fitness; and this one must be supposed to elucidate the concept of adaptation and also to explain the phenomenon to which the last one alludes. These three concepts, on the other hand, are specificationsof three concepts of more universal application. The concept of biological function is a particular case of the general concept of function; and the concept of fitness is a specification of the concept of efficiency. The concept of adaptation, meanwhile, specifies the concept of design. The visualization of these conceptualjoints allows to understanding the legitimacy of the naturalization of the teleology produced by the Darwinism. (shrink)

This book, focusing on the relationship between Derrida and Levinas and the unresolved tension between these two philosophical corpuses, will show what can yet come to democracy and will consequently offer possible interpretations of that which can occur and happen to us politically.

Cet article s’interroge sur la position de Derrida face à la question de l’animal. En particulier, il suit Derrida en quête de ‘l’animal’, d’abord en esquivant la question du langage et du logos – attributs niés à l’être animal par une certaine tradition philosophique –, en s’arrêtant au contraire sur une question qui semble essentielle : l’animal peut-il souffrir ? Mais quel animal ? Il suit dans un deuxième temps Derrida dans sa « passion » pour les animaux, pour suggérer (...) qu’il y a là comme une substitution – christique, messianique, cathartique, parodique ? – de l’un aux autres, ce qui apparaît surtout avec l’expression étonnante « ecce animot ».This article wonders about the way Derrida addresses the issue of animal. It particularly follows Derrida seeking for the ‘animal’, first avoiding the question of language and of logos – attributes refused to animals by some philosophical tradition. On the contrary, it focuses on a question appearing to be essential : can animal suffer ? But which animal ? Secondly, the article follows Derrida in his « passion » for animals, suggesting that there might be as a – christic, messianic, cathartic, parodic ? – substitution of the latters by the former, which appears with the surprising phrase « ecce animot ».

Tout en plaçant Benjamin sur le seuil de la Catastrophe historique et en envisageant ce thème comme un arrière-plan ou comme un paysage désolé, l’objet de ce texte se focalise sur l’idée de catastrophe, considérée à partir des trois perspectives à travers lesquelles Benjamin semble la penser, c’est-à-dire en relation au progrès technique, au continuum historique et à la rédemption. Ce texte montre comment, dans chacune de ces perspectives différentes, il se dévoile un double sens, une dialectique interne à l’idée (...) de catastrophe et comment cette idée est elle même un seuil car, dans son double mouvement, dans son double sens procédant entre un temps de destruction et un contre-temps de rachat, elle se meut entre la fin et le salut, passe de la fin au salut.

By drawing on Jacques Derrida’s analysis of the animal question in his last seminars entitled The Beast and the Sovereign, I approach the possibilities of fraternity not only among beasts, between “the wolf and the lamb,” but also between them and humans, in terms of their differences. More precisely, while illustrating certain limits of his analysis, I look at his decisive inquiry concerning “the animal,” which goes hand in hand with political inquiry. Yet we take this path in the company (...) of the wolf, the metaphorical wolf, and following the French expression “a pas de loup” as used by Derrida, in order to deconstruct the very concept of sovereignty and thus to think of politics beyond politics or otherwise than politics. However, I also bring in Levinas, almost a “wolf ” waiting along the way, to demonstrate how, despite Derrida’s vast work on these questions, he remains imprisoned in what he wishes to deconstruct, as if he were not completely able to extract himself from it.

“Think of the disaster” is the first injunction of thought when faced with the disaster that struck European Jews during the Shoah. Thinking of the disaster means understanding why the Shoah was able to occur in civilized Europe, moulded by humane reason and the values of progress and enlightenment. It means thinking of a possibility for philosophy’s future. Walter Benjamin, who wrestled with these problems ahead of time, Theodor Adorno, Max Horkheimer, and Emmanuel Levinas had the courage, the strength and (...) the perception—and sometimes simply the desperation—to think about what had happened. Moved by indignation and the desire to testify, they felt the urgent need to address the cries of agony of Auschwitz’s victims in their thinking. (shrink)

Las presiones selectivas no son factores ambientales que existan independientemente de los linajes por ellas afectados. Su existencia y su configuración siempre dependen de las alternativas de evolución que el propio linaje genera y acepta; y dicha configuración, necesariamente, se va alterando conforme el propio linaje evoluciona. Aclarar eso es muy importante para desestimar algunas reticencias generadas por la dicotomía próximo-remoto. Esta polaridad continúa siendo un recurso conceptual válido e insustituible para entender la especificidad de la Biología Evolucionaria. Enmendar algunos (...) equívocos generados por Mayr en su caracterización del concepto de causa remota es una alternativa mejor que la de pensar en abandonar o en relativizar esa distinción.

Although the knowledge about biological systems has advanced exponentially in recent decades, it is surprising to realize that the very definition of Life keeps presenting theoretical challenges. Even if several lines of reasoning seek to identify the essence of life phenomenon, most of these thoughts contain fundamental problem in their basic conceptual structure. Most concepts fail to identify either necessary or sufficient features to define life. Here, we analyzed the main conceptual frameworks regarding theoretical aspects that have been supporting the (...) most accepted concepts of life, such as (i) the physical, (ii) the cellular and (iii) the molecular approaches. Based on an ontological analysis, we propose that Life should not be positioned under the ontological category of Matter. Yet, life should be better understood under the top-level ontology of “Process”. Exercising an epistemological approach, we propose that the essential characteristic that pervades each and every living being is the presence of organic codes. Therefore, we explore theories in biosemiotics and code biology in order to propose a clear concept of life as a macrocode composed by multiple inter-related coding layers. This way, as life is a sort of metaphysical process of encoding, the living beings became the molecular materialization of that process. From the proposed concept, we show that the evolutionary process is a fundamental characteristic for life’s maintenance but it is not necessary to define life, as many organisms are clearly alive but they do not participate in the evolutionary process (such as infertile hybrids). The current proposition opens a fertile field of debate in astrobiology, epistemology, biosemiotics, code biology and robotics. (shrink)

RESUMEN: La idea de selección interna, propuesta originalmente por Lancelot Whyte, no sólo sirve para entender el papel causal que los constreñimientos del desarrollo tienen en evolución; sino que además puede hacernos comprender de qué modo esos factores organísmicos o internos, cuya importancia la Biología Evolucionaria del Desarrollo hoy quiere rescatar, son pasibles de ser considerados desde una perspectiva variacional o seleccional compatible, pero no asimilable, a la Teoría de la Selección Natural. Así, considerado como un concepto autónomo y diferente (...) al de selección natural, el concepto de selección interna puede permitirnos comprender de qué modo eso que Wallace Arthur llama developmental bias constituye una causa, efectiva y positiva, de transformacionesevolutivas irreversibles y acumulables.ABSTRACT: The idea of internal selection, originally proposed by Lancelot Whyte, not only helps to understand the causal role that the developmental constraints have in evoltion, but it can also show how these organismic or internal factors, which relevancy the Evolutionary Developmental Biology remarks today, can be considered from a variational or selectional perspective that is compatible with, but not reducible to, Natural Selection Theory. Thus, being considered as a concept autonomous and different from natural selection, the concept of internal selection can allow us to understand how that phenomenon that Wallace Arthur calls developmental bias constitutes an effective and positive cause of irreversible and cumulative evolutionary changes.

Firstly, in this article it is examined the nature of the putative remarks concerning evolution of species that are found in the works that Richard Owen published before 1858; and then it is made the same thing with the few and vague evolutionist conjectures that Owen certainly made after the public presentation of Natural Selection Theory. Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for (...) is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

La idea de herencia extendida se ha transformado en un leitmotiv de lo que se ha dado en llamar ‘síntesis extendida’. Dicha idea, entretanto, lleva a ignorar una de las marcas distintivas de lo que clásicamente se ha entendido por transmisión hereditaria: su estrecha asociación con el proceso de reproducción. Sin considerar tal asociación, la noción de herencia, más que ampliarse, de hecho se disuelve; y aceptar esa disolución acarrearía demasiadas dificultades para el discurso de las ciencias biológicas. Una de (...) esas dificultades tiene que ver con el concepto de variación hereditaria. Con la disolución de la noción de herencia, ese concepto también se disolvería; y, sin éste, la Teoría de la Selección Natural no puede articularse. Pero, no habiendo motivos valederos para aceptar semejante costo teórico, aquí quiero mostrar que ambos conceptos, el de herencia y el de variación hereditaria, pueden y deben ser elucidados sin aceptar la idea de herencia ampliada.

The main cognitive target of Ecology is the functional analysis of the ecological processes and systems. It does not suppose, meanwhile, that these processes and systems are designed systems and processes like individual leaving beings. The Ecology, likewise Physiology, is constitutively guided by the presupposition of a privileged state , to be explained, that it is the persistence of the systems and processes that she studied; and its functional analyses obey to this presupposition. Ecology supposes an ideal of natural order (...) , under which consideration this privileged state is thinking as an improbable state of things and, for that, needed of explanation; and, in what concerns this latter point, the analogy between Ecology and Physiology can also result instructive.

Having as starting point that a proximal cause is one which effects can be registered in the states of an individual organism, in this work I will argue that what defines an ultimate cause is the fact that its effects can be registered in the evolution of lineages, and not simply in population states. This, on the other hand, not only will allow us to clarify how the developmental constraints can be understood as causes of the evolutionary phenomena; but also (...) it will allow us to point the eminently historical character of Developmental Evolutionary Biology that Wallace Arthur lessened in Biased Embryos and Evolution. Thus, and following this latter reasoning, I will also try to show that, although the action of developmental constraints could happen beyond the limits of a population or a particular species, that does not imply that we are before a comeback of typological thought in Evolutionary Biology.

El articulo adopta una perspectiva histórica y crítica con relación al modelo hegemónico de salud mental, centrado en la necesidad de restaurar farmacológicamente un desequilibrio neuroquímico. En el campo de la psiquiatría parece haber un amplio acuerdo en defender la tesis según la cual, entre los años 1952 y 1954, con el descubrimiento del primer neuroléptico, la Clorpromazina, se iniciaría un proceso de radical transformación del saber psiquiátrico.

Tomando como ponto de partida os trabalhos de Nietzsche, Hannah Arendt e Michel Foucault, este escrito pretende problematizar a lógica interna da compaixão piedosa, pois, como tentaremos mostrar, ela parece instaurar uma modalidade peculiar de exercício de poder que se estrutura a partir do binômio servir-obedecer. A partir desses autores, pretendemos ler alguns exemplos que a história da humanidade nos apresenta para ilustrar o exercí- cio dessa “cruel compaixão”.

En sus Principios de biología de 1864, Spencer esboza una complementación entre el cuvierianismo transformacional mitigado que daba sentido a la idea de equilibración directa ahí presentada, y la teoría de la selección natural que Darwin ya había formulado en 1859. Era a este último mecanismo que Spencer denominaba "equilibración indirecta". Según Spencer, esta segunda forma de equilibración permitía explicar fenómenos evolutivos que la primera, la equilibración directa, no podía causar; aunque para él también era evidente que el accionar de (...) esa segunda equilibración debía siempre subordinarse al control de la primera. In his Principles of Biology, published in 1864, Spencer outlines a complementarity between the mitigated transformational cuvierianism that was in the basis of his idea of direct equilibration, and the theory of the natural selection that Darwin had already formulated in 1859. Spencer called the mechanism of natural selection indirect equilibration. According to him, this second form of equilibration enabled the explanation of some evolutionary phenomena that could not be caused by direct equilibration. However, for Spencer, it was clear that the operation of this second equilibration had to be always subordinated to the control of the first one. (shrink)

En este artículo, nos proponemos analizar el horizonte epistemológico sobre el que se construye la psiquiatría de Kraepelin, particularmente su posición frente al problema de los criterios de clasificación de las enfermedades mentales, que fue un tema ampliamente discutido por la psiquiatría mundial a fines del siglo XIX. Analizamos de qué modo Kraepelin se vinculaba con el debate de su época sobre la definición de criterios científicos, válidos y objetivos de clasificación de las enfermedades psiquiátricas, para, posteriormente, analizar las consecuencias (...) implícitas en una elección de criterios diagnósticos que significó el abandono de las narrativas de los pacientes frente a la fantasmagoría de las categorías diagnósticas. In this paper we analyze the epistemological framework on which Kraepelin's psychiatry was built. We are particularly interested in Kraepelin's position relating to the criteria of classification of mental illnesses; a topic that was widely discussed by in psychiatry throughout the world at the end of the XIX century. We analyze his contributions to the discussion concerning the definition of scientific and objectively valid criteria for the classification of psychiatric illnesses. Then, we show how settling upon certain diagnostic criteria led to paying little attention to patients narratives, and giving major weight to the paraphernalia of diagnostic categories. (shrink)
