Desde los orígenes de su formación en fenomenología, Heidegger emprendió modificaciones metodológicas que tematizan el campo de la vida preteórica y llevan a la hermenéutica del Dasein creando tensiones respecto de Husserl que afectaron tanto la dimensión teórica como la personal. En este trabajo se estudia este viraje señalando sus orígenes tempranos y concentrándose en los aportes del curso Introducción a la investigación fenomenológica, del semestre de invierno de 1923/1924. Este ámbito presenta aspectos relevantes para comprender el modo en que (...) se redefine la noción de fenomenología, la estrategia de impugnación de la posición husserliana por su cartesianismo y los puntos que distancian las perspectivas respecto de la conciencia y la facticidad. El recorrido resultante ofrece elementos para comprender los puntos que llevarían poco más tarde a la fricción entre ambos pensadores que marcó profundamente la filosofía contemporánea. (shrink)

Resumen Husserl emprendió varias presentaciones sintéticas de la fenomenología con el propósito de darla a conocer ante públicos amplios. En el presente trabajo estudiaremos el enfoque de las Conferencias de París, su proyección en las Meditaciones cartesianas y el destino del proyecto de la versión alemana en tensión con la redacción del Sistema de filosofía fenomenológica, a los efectos de establecer sus rasgos distintivos, evaluar los alcances del abandono del neocartesianismo, que suele asociarse con el último período de producción de (...) Husserl y, situar la dirección de estas últimas presentaciones en el clima intelectual que les dio origen.Husserl undertooks several synthetic presentations of phenomenology in order to make it known to broader audiences. In the present work we will study the approach of the Paris Lectures, their projection in the Cartesian Meditations and the idea of the German version in tension with the writing of the System of phenomenological philosophy, in order to establish its distinctive features, to evaluate the abandonment of neocartesianism that is usually associated with the last period of Husserl's production and to identify the direction of these presentations in the intellectual climate that gave rise to them.

Resumen Las distintas dimensiones de la investigación fenomenológica y su vínculo intrínseco con las cuestiones de método llevan a prestar atención a la esfera de lo inaparente, y especialmente a la cuestión del acceso al plano trascendental. El inicio de la discusión se remonta al planteo sobre el abandono -o no- del cartesianismo en Husserl, tema que devino un tercer problema asociado con las vías de acceso a la reducción. En este trabajo estudiaremos este decurso con objeto de sugerir que (...) los desarrollos sobre generatividad y filosofía de lo inaparente invitan a redefinir el problema en términos más generales, explorando qué accesos a lo trascendental se despliegan en las diversas dimensiones de investigación fenomenológica. En este sentido, seguiremos la deriva de las dos primeras discusiones para bosquejar finalmente las direcciones que surgirían en una labor de desarrollo de la tercera.The different dimensions of phenomenological research and its intrinsic link to methodology lead to pay attention to this area and, within it, especially to the ways to transcendental dimension. The beginning of this discussion goes back to the abandonment -or absence of abandonment- of Cartesianism in Husserl, an issue that became a third problem in the issue of the ways to reduction. In this paper we study these problems in order to suggest that developments on generativity and phenomenology of the inapparent redefine the problem in more general terms, exploring the ways leading into the transcendental realm that unfold in the various dimensions of phenomenological research. In this regard, we will continue the first two discussions and finally point out the directions that arise in the development of the third question. (shrink)

La fenomenología tiene una fuerte impronta asociada con el método, que dio lugar a numerosos desarrollos teóricos. Por esta vía más tarde recibió cuestionamientos profundos en relación con una supuesta falta de radicalidad, derivada de las limitaciones impuestas por su compromiso con la estructura intencional. Una revisión de esta esfera, atendiendo a la tematización de la excedencia, muestra la pertinencia de incorporar la fenomenología de lo inaparente a los estratos de estaticidad, geneticidad y generatividad; además, permite morigerar estos cuestionamientos sumándolos (...) como rendimientos de la disciplina. En este trabajo consideraremos algunos aspectos centrales sobre el método de la fenomenología, para establecer luego los rasgos de una dimensión orientada a la excedencia y sugerir, finalmente, como ejemplo de esta dirección teórica, que el contramétodo marioniano es compatible con la fisonomía que adopta la intencionalidad morigerada propia del plano de la fenomenología de lo inaparente.

En vistas de una revisión general de la noción de sujeto, Michel Henry objeta, por un lado, su asociación con la representación y, por otro, el tratamiento de la alteridad presentada de manera intencional. Apunta con ello a mostrar en qué sentido la intencionalidad y la constitución no son las vías fenomenológicas adecuadas para dar cuenta del a priori universal de la experiencia de la alteridad. En rigor, la posición henryana sobre la crítica del sujeto no sólo pone en cuestión (...) las presentaciones noemáticas de la alteridad, sino que se extiende hacia todo intento de dar cuenta del Otro desde una perspectiva que no sea auto-afectiva. Sin embargo, lo que a primera parece irreconciliable con el horizonte fenomenológico husserliano, puede resultar un aporte sustantivo en este mismo terreno. Examinaremos aquí la crítica a la postura husserliana para establecer una clave de lectura que no provoque una colisión entre ellas sino una sinergia que, retomando la potencia de los orígenes, despliegue un programa de investigación que abarque el estudio de todo el arco de la fenomenicidad.

El presente trabajo aborda el tratamiento del “caso Schneider” que MerleauPonty lleva adelante a partir de los análisis neuropsiquiátricos de K. Goldstein. Esto se conecta directamente con el problema del status que adquiere el discurso científico en un modelo que adopta como marco la fenomenología. Mostraremos que este recurso, lejos de implicar un alejamiento de este modelo teórico, constituye un caso de reducción a la experiencia de sujetos cuyo “arco intencional” se presenta distendido y están, por ello, en condiciones de (...) ofrecer datos equiparables a los que se obtienen al amparo de la reducción fenomenológica.This paper addresses the treatment of the Schneider’s case that Merleau-Ponty accomplished from the neuropsychiatric analysis of K. Goldstein. This issue is directly connected with the problema of the status of scientific discourse into a model that adopts a phenomenological framework. It will be shown that this resource, far from implying a departure from this theoretical model, is a case of reduction to the experience of subjects whose “intentional arch” appears relaxed and are therefore able to provide data comparable to those obtained under phenomenological reduction.

The Idea of Phenomenology is the result of the first course in which Husserl presented disciplinary developments after the transcendental turn occurred around 1905. It is therefore not only an important document of this turning, but also a high-impact work on the subsequent phenomenological tradition. In this paper we study three aspects of the category of enigma : the way in which it characterizes transcendence, the figure of objectors and the issue of donation and its modes. This analysis will highlight (...) unexplored aspects of transcendental phenomenology at its early stages. (shrink)

Platón delinea la filosofía como una disciplina que supera otros modos discursivos, como la poesía y la retórica, sugiriendo que deben ser transformados y orientados a criterios objetivistas con la dialéctica como parámetro en la cual tiene importancia central el mecanismo de la refutación. El presente trabajo se propone examinar este punto en el Eutidemo, prestando atención a la figura de Marsias para describir a Sócrates e identificar rasgos de la metodología platónica, y, sobre esta base, elucidar la relación entre (...) protréptico y dialéctica en el programa de construcción de un modelo antierístico. Plato outlines Philosophy as a discipline that surpasses other genres, like poetry and rhetoric, and suggests that they must be transformed and oriented towards objectivism, and dialectic would be a parameter in which refutation is of central importance. This paper examines this aspect in the Euthydemus, considering the figure of Marsyas in order to describe Socrates and to characterize platonic methodology. On this base it is posible to elucidate the relationship beween protreptic and dialectic in the construction of an antieristical model. (shrink)

Resumen La filosofía de Michel Henry llevó adelante una propuesta de radicalización de la fenomenología que apela a una puesta en primer plano de la afectividad como expresión de la Vida. Para dar cuenta de la especificidad de este viraje adoptó las categorías opositivas de gnosis griega y gnosis cristiana, la primera asociada con el compromiso de la descripción del mundo en su exterioridad y la segunda vinculada con la experiencia de la carne. Sin embargo, entre las filosofías de la (...) antigüedad griega se halla el caso de la posición de los cirenaicos, que preanuncia numerosos rasgos del tratamiento henryano de la afectividad. Este trabajo estudia esta relación repasando los puntos centrales de la caracterización henryana de gnosis griega para conectarla luego con los presupuestos centrales de la filosofía cirenaica y sus tesis acerca de las afecciones, el tacto interno y el diseño de un lenguaje que refleje la afectividad. Este recorrido permitirá sopesar los alcances de la tesis acerca de la homogeneidad de la gnosis griega y mostrará una deriva importante de antecedentes respecto del pensamiento de la inmanencia.The philosophy of Michel Henry carried out a proposal of radicalization of phenomenology, which appeals to a foregrounding of affectivity as an expression of Life. In order to account for this turn, he proposed the opposing categories of Greek gnosis and Christian gnosis. The first one is associated with the commitment of describing the world in its exteriority and the second one is linked to the experience of the flesh. However, among the philosophies of Greek antiquity, the Cyrenaics raised many issues similar to those of the henryan treatment of affectivity. This work studies this relationship by reviewing the main aspects of the henryan characterization of Greek gnosis and then connects it with the key points of the Cyrenaic philosophy about affection, internal tact and the design of a language that reflects affectivity. This exploration will allow us to evaluate the scope of the thesis about the homogeneity of the Greek gnosis and will show important factors of the ancient thought about immanence. (shrink)

ABSTRACT Husserl endeavored to develop approaches to phenomenology that would facilitate its expansion. In "Philosophy as Rigorous Science", he provides a diagnosis of the obstacles found in the interweaving of naturalism and historicism, and analyzes the logic of its construction by means of three themes: the appeal to psychologism as an element of naturalism, the interpretation of Hume as a proto-phenomenologist, and the historicist reading of Dilthey. This makes it possible to obtain relevant information regarding the manner in which Husserl conceived the specificity and scope of phenomenology during that period. (shrink)

Resumen Numerosas derivas de la fenomenología contemporánea, especialmente francesa, tematizaron fenómenos con excedencia que desafían la estructura husserliana de correlación intencional e impronta epistémica del polo subjetivo. La filosofía heideggeriana se pregunta sobre la facticidad y sus fundamentos, arribando al terreno en que el fenómeno se sustrae y resulta, por ello, inaparente, pero a la vez fundante de todo el ámbito del aparecer. En el presente trabajo estudiaremos en primer lugar el marco en que la filosofía de Heidegger tematiza la (...) excedencia en el Seminario de Zähringen, consideraremos la tensión con la posición husserliana y analizaremos el planteo de la noción de “fenomenología de lo inaparente” para trazar algunas proyecciones de esta idea que habilitan la inclusión de las temáticas ligadas con la excedencia dentro de la economía propiamente fenomenológica.Many lines of contemporary phenomenology, especially in its French sides, have studied phenomena that exceed the limits and defy the original Husserlian structure and its commitment with intentional correlation and the epistemic aspects of the subjective pole. The direction of Heideggerian philosophy and its treatment about facticity and its foundations was a defining issue. In this context it is studied the phenomenon that subtracts itself and is, therefore, inapparent, but at the same time it is the founder of the whole field of appearance. The present work mil study the framework in which Heidegger's philosophy thematizes excess in the Seminar of Zähringen. It mil be considered the tension with the Husserlian position and the propos al of the notion of'phenomenology of the inapparent". On this basis it mil be possible to draw some projections of this idea that enable the inclusion of the issues linkedmth exceedance within the phenomenological sphere. (shrink)

We present a fully relational definition of inertial systems based in the No Arbitrariness Principle, that eliminates the need for absolute inertial frames of reference or distinguished reference systems as the ``fixed stars'' in order to formulate Newtonian mechanics. The historical roots of this approach to mechanics are discussed as well. The work is based in part in the constructivist perspective of space advanced by Piaget. We argue that inertial systems admit approximations and that what is of practical use are (...) precisely such approximations. We finally discuss a slightly larger class of systems that we call ``relatively inertial'' which are the fundamental systems in a relational view of mechanics. (shrink)

While mechanics was developed under the idea of reciprocal action (interactions), electromagnetism, as we know it today, takes a form more akin to unilateral action. Interactions call for spatial relations, unilateral action calls for space, just one reference centre. In contrast, interactions are matters of relations that require at least two centres. The development of the relational electromagnetism encouraged by Gauss appears to stop around 1870 for reasons that are not completely clear but are certainly not solely scientific. By the (...) same time, Maxwell recognised the equivalence in formulae of his electromagnetism and the one advocated by Gauss and called for an explanation of why such theories so differently conceived have such a large part in common. In this work we reconstruct and update the relational electromagnetism up to the contributions of Lorentz guided by the non-arbitrariness principle (NAP) that requests arbitrary choices to be accompanied by groups of symmetries. We show that a-priori there must be two more symmetries in electromagnetism, one related to the breaking (in the description) of the relation source/detector and one relating all the perceptions of the same source by detectors moving with different (constant) relative velocities. We show that the idea of electromagnetic waves put forward in concept by Lorenz (1861-1863) before Maxwell (1865) and in formulae (1867) just after Maxwell, together with the ``least action principle'' proposed by Lorentz are enough to derive Maxwell's equations, the continuity equation and the Lorentz' force, and that there is a dual formulation in terms of fields of the receiver (as opposed to fields of the source). While Galilean transformations are associated with removing the arbitrariness implied in the election of a reference space, they will not explicitly appear in a formulation based upon a relational space although we occasionally mention their usefulness. In contrast, Lorentz' transformations will emerge in this formulation involving the relations between the perceived fields of different receivers. Moreover, the role of the full Poincaré-Lorentz group as a group of transformations of the perceived actions is elucidated. In summary, we answer Maxwell's philosophical question showing how the same theory in formulae can be abduced using different inferred entities. Each form of abduction implies as well an interpretation and a facilitation of the theoretical construction. This work relies heavily on logical concepts as abduction put forward by C. Peirce, needed for the construction of theories. (shrink)

La comprensión de lo histórico por medio de la “revivencia” en Dilthey confluye con la idea de re-enactment en la teoría de la imaginación histórica de Collingwood a través de la autognosis.

Así, las tradiciones del empirismo y del idealismo se acercan en aras de una reflexión sobre (...) la actividad efectiva del historiador. Se analiza, entonces, cuál es el rol de la autoconciencia en el conocimiento humano, atendiendo a las diferencias entre la psicología de ambos pensadores. (shrink)

The prospective formalization of the Anthropocene as a chronostratigraphic unit by the International Commission on Stratigraphy has been intensely debated. This paper explores and assesses the stakes of this process from a philosophical perspective. I distinguish two senses of formalization—the descriptive and the evaluative—and argue that: 1) there are descriptive and evaluative formalizations of the Anthropocene beyond the confines of the ICS; 2) incoherencies between Anthropocene proposals and the ICS’s current tenets are not a decisive reason for deferring descriptive formalization; (...) and 3) the prospective evaluative formalization of the Anthropocene by the ICS would be impactful.

The purpose of this study was to analyze the attitude of a group of cardiologists on the ethical conducts they would accept or adopt when encountered with different hypothetical situations of medical practice. Between August and September of 2011, 700 Argentine cardiologists were surveyed in situations which posed ethical dilemmas in the patient-physician relationship, among colleagues or involving financial agreements with employers or the pharmaceutical industry. Ethical conflicts were evidenced in a series of inappropriate conducts such as differential fees, trips (...) and meals sponsored by laboratories, splitting fees, overbilling, self-referral, charging for patient referral, financial compensation for ordering medical procedures, and various situations derived from the relationship with employers. In general, financial compensation from the pharmaceutical industry was more accepted than the conflictive situations which directly involved patients, colleagues or employers. The rejection of these conducts, the physicians' deontological education and the improvement of financial and organizational conditions in medical practice will help to encourage better medical professionalism and avoid unseemly behaviors.

Our purpose is to describe the application of legitimate defense in so-called non-confrontational situations. To do this, we will conceptualize gender violence as that which against women, due to their condition as such, and we will describe the absence by the courts in the identification of this problem. Second, we will analyze the reception of Argentine and international legislation on the treatment of gender violence and the recommendations and criteria to take into account when interpreting and applying criminal law. Finally, (...) we will present the treatment of legitimate defense in contexts of gender violence, analyzing each of its elements. Our conclusions will focus on the need to address situations of gender violence based on international regulations for the application of legitimate defense in non-confrontational situations.

Se adapta al título del libro de Andre Gunder Frank para proponer un esquema de conjunto de la historia americana desde una visión no eurocéntrica y desde la historia mundial. El acento no se coloca en la relación del continente con la Europa mediterránea o atlántica, ni en procesos endógenos, sino en los contactos que mantuvo con las otras civilizaciones del Viejo Mundo: África, la Europa oriental, Rusia, el Medio Oriente, India, China y el Pacífico. Se argumenta que antes de (...) la llegada europea hubo una etapa fuertemente influida por las relaciones con Asia. Éstas continuaron aún en época colonial, en términos comerciales, demográficos y artísticos, junto a una fuerte inmigración e influencia cultural africana. Si bien la independencia supuso una serie de ilusiones sobre el fomento de las relaciones con Asia, el siglo xix fue de creciente influencia europea (demográfica, militar, política, económica, cultural). El esquema propuesto puede servir para entender mejor los procesos por los cuales en nuestros días América, como el resto del mundo, está entrando nuevamente en la órbita asiática. (shrink)

During the second half of the nineteenth century, electronegativity has been one of the most relevant chemical concepts to explain the relationships between chemical substances and their possible reactions. Specifically, EN is a property of the substances that allows them to attract external electrons in bonding situations. The problem arises because EN cannot be measured directly. Indeed, the only way to measure it is through different properties that do can be directly measured, for instance enthalpy, ionization energies or electron affinities. (...) What is particularly troubling about this case in quantum chemistry is that the different models used to describe and quantify EN are incompatible but, in a certain sense, equivalent because the same EN scale results in all of them. By analyzing Linus Pauling’s and Robert Mulliken’s models of EN, it will be argued that, if we remain cling to a traditional representative conception of models, we cannot understand the meaning of the information provided by those models. Indeed, if we do not want to adopt an instrumentalist point of view concerning chemical knowledge, we should reconsider by virtue of what a model represents the system, or, in other words, which the factors that determine the representative power of a model are. I will propose a new perspective that incorporates the role of experimental techniques in the very notion of representation; this perspective allows us to understand how supposedly incompatible models of the same target system can be both simultaneously representative. (shrink)

The incompatibility within the context of modeling cannot be established simpliciter. The fact that modeling is understood as an activity whose representational power can only be partially established, may minimize the supposed existence of incompatible models. Indeed, it is argued from perspectivism that incompatibility can be dissolved, meaning that it becomes trivial or simply false due to the inherently pragmatic and partial nature of the act of representation and modeling. From this perspective, incompatibility can only be a consequence of a (...) misunderstanding of the very nature of modeling and representation In this sense, in order to tackle this strategy at its root from perspectivism, we will first need to outline the maximal perspectivism thesis, attempting to identify the possible escape routes that perspectivism could find in order to explain incompatibility as an illusory incompatibility. Then, we will analyze Valence Bond Model and Molecular Model of covalent bonds, and we will conclude that the dissuasive strategies used to minimize and/or disregard incompatibility prove to be fruitless.

Multiple studies show that periodic reanalysis of genomic test results held by clinical laboratories delivers significant increases in overall diagnostic yield. However, while there is a widespread consensus that implementing routine reanalysis procedures is highly desirable, there is an equally widespread understanding that routine reanalysis of individual patient results is not presently feasible to perform for all patients. Instead, researchers, geneticists and ethicists are beginning to turn their attention to one part of reanalysis—reinterpretation of previously classified variants—as a means of (...) achieving similar ends to large-scale individual reanalysis but in a more sustainable manner. This has led some to ask whether the responsible implementation of genomics in healthcare requires that diagnostic laboratories routinely reinterpret their genomic variant classifications and reissue patient reports in the case of materially relevant changes. In this paper, we set out the nature and scope of any such obligation, and analyse some of the main ethical considerations pertaining to a putative duty to reinterpret. We discern and assess three potential outcomes of reinterpretation—upgrades, downgrades and regrades—in light of ongoing duties of care, systemic error risks and diagnostic equity. We argue against the existence of any general duty to reinterpret genomic variant classifications, yet we contend that a suitably restricted duty to reinterpret ought to be recognised, and that the responsible implementation of genomics into healthcare must take this into account.

The use of genomic testing in pregnancy is increasing, giving rise to questions over how the information that is generated should be offered and returned in clinical practice. While these tests provide important information for prenatal decision-making, they can also generate information of uncertain significance. This paper critically examines three models for approaching the disclosure of variants of uncertain significance (VUS), which can arise from forms of genomic testing such as prenatal chromosomal microarray analysis (CMA). Contrary to prevailing arguments, we (...) argue that respect for reproductive autonomy does not justify adopting a model on which an offer to disclose VUS is a routine part of genetic counselling. Instead, we contend that a commitment both to solidarity between healthcare providers and pregnant women and to the acceptance of a novel principle of caution under normative uncertainty means that we should instead adopt a model of VUS disclosure that imposes a strong presumption against offering to disclose VUS. The upshot of this is that it should be standard practice to only offer to disclose VUS when this is requested by the woman undergoing CMA. We defend our position against claims that arise from an alleged right to such information and that a presumption against an offer will lead to inequity. (shrink)

Las fallas predictivas obligan a alguna modificación en las teorías, lo cual, en muchos casos, consiste en detectar algún factor que ha interferido en el experimento. Podría ser que se tratara de un factor de un tipo ya reconocido por la teoría o bien que fuera necesario proponer un factor de un tipo no conocido hasta el momento. En este trabajo proponemos un ordenamiento de los cambios en las teorías de acuerdo con el tipo de factor propuesto en la modificación. (...) Este ordenamiento puede utilizarse para distinguir los cambios en ciencia normal de los cambios revolucionarios. Nuestra propuesta se realiza sobre la base de que una teoría admite únicamente un número finito de tipos de factores. /// The failure of a prediction forces some modification of the theory, which in many cases means locating some factor that interfered in the experiment. A factor may be found of a type already recognized by the theory. Or it may be the case that it becomes necessary to propose an as yet unknown factor. Here we suggest an ordering of theory changes according to the type of factor proposed. The ordering may be used to distinguish normal change from revolutionary change. Our proposal is based on the thesis that a theory admits only a finite number of types of factors. (shrink)

We integrate dualistic conceptions of the real with Peirce's perspectives about reality and abduction, emphasizing the concept of reason underlying Peirce's thoughts. Peirce's abduction is related to the notions of retrogression and grounding in Hegel, later re-encountered in Hansonian-abduction. Abduction in turn is considered in relation to abstraction acquiring its fullest sense as a stage in the process of producing a theory. The process is iterative and self improving, it incorporates ``turbid thinking'' making it increasingly ``clear'' at successive iterations that (...) incorporate the lessons taught by failed predictions, i.e., refutations. The cycle of thoughts promoted by doubts comes to rest when belief is reached. We discuss how this coming to rest depends on a criterion for cessation of doubts. The observation is illustrated with two different criteria, one proposed by Mach that only demands analogy and the criteria of dualists such as Goethe and Whewell that inspire the present work. Hence, it is possible to produce, and socially accept, imperfect theories unless we demand the highest level of rationality, avoiding any leftover of the turbid thoughts that have been used in the early developments. This work rests upon the existence of some objective form of reason. Influenced by a constructivist, Piagetian, perspective of science, we propose and discuss a small number of conditions that we identify as characteristics of rational abduction: rules for the rational construction of theories. We show how a classical example of belief that satisfies today's most common definition of abduction does not match the standards of rational retroduction. We further show how the same rules indicate the partial detachment of Special Relativity from the observable world, a fact actually known to Einstein. We close arguing that there is an urgent need to develop a critical epistemology incorporating dualistic perspectives. (shrink)

Artificial intelligence (AI) has become nearly ubiquitous in modern society, from components of mobile applications to medical support systems, and everything in between. In societally impactful systems imbued with AI, there has been increasing concern related to opaque AI, that is, artificial intelligence where it is unclear how or why certain decisions are reached. This has led to a recent boom in research on “explainable AI” (XAI), or approaches to making AI more explainable and understandable to human users. In the (...) military domain, numerous bodies have argued that autonomous and AI-enabled weapon systems ought not incorporate unexplainable AI, with the International Committee of the Red Cross and the United States Department of Defense both explicitly including explainability as a relevant factor in the development and use of such systems. In this article, I present a cautiously critical assessment of this view, arguing that explainability will be irrelevant for many current and near-future autonomous systems in the military (which do not incorporate any AI), that it will be trivially incorporated into most military systems which do possess AI (as these generally possess simpler AI systems), and that for those systems with genuinely opaque AI, explainability will prove to be of more limited value than one might imagine. In particular, I argue that explainability, while indeed a virtue in design, is a virtue aimed primarily at designers and troubleshooters of AI-enabled systems, but is far less relevant for users and handlers actually deploying these systems. I further argue that human–machine teaming is a far more important element of responsibly using AI for military purposes, adding that explainability may undermine efforts to improve human–machine teamings by creating a prima facie sense that the AI, due to its explainability, may be utilized with little (or less) potential for mistakes. I conclude by clarifying that the arguments are not against XAI in the military, but are instead intended as a caution against over-inflating the value of XAI in this domain, or ignoring the limitations and potential pitfalls of this approach.

Recent discussions about the microstructure of materials generally focus on the ontological aspects of the molecular structure. However, there are many types of substances that cannot be studied by means of the concept of molecule, for example, salts. For the quantum treatment of these substances, a new particle, called phonon, is introduced. Phonons are generally conceived as a pseudo-particle, that is, a mathematical device necessary to perform calculations but which does not have a “real” existence. In this context, the aim (...) of this paper will be to analyze the ontological status of phonons. For such purposes we will critically analyze the arguments that would account for the presumed nonexistence of phonons. Finally, having already demonstrated that there are not enough reasons to consider phonons as non-existing entities, we will explore some possibilities that allow us to elucidate their ontological status.

Este recorrido lleva al lector por el método de interpretación textual de los evangelizadores de varias épocas; por el acceso al texto, para su lectura e interpretación y por la teología subyacente.
