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.

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.

A los cristales se los describe como a una red de átomos que puede vibrar alrededor de su posición de equilibrio. Sin embargo, el hecho de que la energía de estas ondas esté cuantificada sugiere una analogía con el campo electromagnético. En analogía con el fotón se define al fonón. Generalmente se concibe al fonón como a una cuasi-partícula, es decir, como a un instrumento matemático útil en los cálculos pero sin una existencia propia. En este trabajo estudiamos el estatuto (...) ontológico del fonón y argumentaremos en favor de la idea de considerarlo como una partícula real. (shrink)

La concepción semántica de las teorías científicas supone la dependencia de los modelos respecto de las teorías. Algunos autores desafian tal supuesto a través del estudio de ciertos modelos concebidos como fenomenológicos. Sobre la base del análisis de los modelos atómicos y moleculares en quimica cuántica, en el presente artículo se argumentará en favor de una independencia de los modelos respecto de las teorías que no puede interpretarse como meramente histórica y relativa al contexto. Estos modelos ponen de manifiesto una (...) independencia conceptual, constitutiva del proceso de modelización, que no resulta de una deficiencia contingente de la teoría, deficiencia que sería resuelta por el progreso futuro de la ciencia.The semantic view of scientific theories assumes the dependence of models on theories. Some authors challenge that assumption by means of the study of certain models conceived as phenomenological. On the basis of the analysis of atomic and molecular models in quantum chemistry, in this article we will argue for an independence of models from theories, which cannot be interpreted as merely historical and context relative. Those models shows a conceptual independence that is constitutive of the modeling process; such independence cannot be conceived as a result of a contingent deficiency of the theory used, deficiency that would be overcome by the future progress of science.

Scientific pluralism has gained supporters in philosophy of science during the last decades, since it seems to accurately account for the plural and varied development of science. Arguments in defense of robust, non-merely epistemic pluralistic positions can be found in several contemporary philosophical works. According to these positions, to hold pluralism does not suppose to assume an epistemic position regarding truth and a non-realistic view on scientific theories. Monism can be thought as the “natural” opponent of scientific pluralism. In this (...) paper, we will evaluate the alleged rivalry between the two positions, paying special attention to those riskier, ontologically more robust, pluralistic proposals. We will argue that these strongest versions of pluralism fail to offer an alternative to monism: they either changes the topic or hold a weak skepticism that Hegel develops in the Phenomenology of the Spirit.

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.

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)

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)

Constructivist research in Science and Technology Studies is committed to revealing the heterogeneity of technological change and the fluid boundaries between the elements involved. Its major theories, the Social Construction of Technology and Actor Network Theory, have however both been criticized for limiting themselves to the micro-level of cases, impeding a structural analysis of technological systems. This article seeks to bridge any such divides. We research the recent changes in the viticulture of Mendoza, Argentina, which underwent radical changes over the (...) past decades: once governed by low-cost yield maximization, grape production now revolves around “quality.” To show how the particular quality definition developed, we depart from a social-constructivist framework, following the sociotechnical shaping of problem-solution relationships across the wine production system. To include relevant social groups from different settings around the world, we gradually incorporate the ANT concepts of obligatory passage points, enrollment, convergence, delegation, and codes into the analysis. Combined into the concept of “sociotechnical alliance,” our analysis follows the dual process of creating agreement while establishing heterogeneous practices across settings at different levels. It shows that functioning involves alliance building and highlights the hybridity and continuous dynamics of systems at large. (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.

Since its inception, quantum mechanics has faced a series of “mysteries” that emerge from it if we consider this scientific theory from a realistic point of view. In the early development of the theory, scientists like Albert Einstein noticed the consequences of accepting a theory like this, which allow phenomena such as non-locality. This led a part of the scientific community to believe that quantum mechanics was an incomplete theory, since there should be variables that might explain those “disturbing” phenomena (...) such as the correlation between entangled particles.Different interpretations of quantum mechanics have been proposed that have tried to reveal or explain the reality underlying its formalism. One of those interpretations is the “Transactional Interpretation” of quantum mechanics, advocated mainly by physicist John G. Cramer. According to this interpretation, quantum events are understood as causal interactions between delayed waves traveling forward in time and advanced waves traveling backward in time. This interpretation opens the door to accept a model of causation to the past or retrocausation.Authors like Phil Dowe or Huw Price have shown a favorable attitude toward the model of retrocausation because it seems to be capable of effectively solve some of the most disturbing features derived from quantum mechanics. Despite the intuitive cost is rather high, retrocausation is one of the possible interpretations for the results of the correlation between entangled particles to provide us with an explanatory framework with some interesting advantages.In this paper we explore such advantages, as the retrocausation gives us a generalizable explanatory model for all cases of this type and assumes processes and entities that are not only in the field of speculation but allow certain possibilities of testing. Also, we will rescue the importance of not-predictive explanatory models as has been the case in other fields of natural sciences, provided that those model do not be ad hoc due to restrictions that prevent its application to any case.

Behavioral momentum theory has evolved within the realm of operant conditioning. The thought-provoking momentum metaphor equates the strength of an operant response with its resistance to change and preference (i.e., choice) for that response over other available responses. Whereas baseline response rate (velocity in the metaphor) is assumed to be largely influenced by the response-reinforcer contingency, resistance to change and preference are assumed to reflect an intervening variable called behavioral mass, which is determined primarily by the stimulus-reinforcer relationship. This invites (...) the question of how well the momentum metaphor applies to the stimulus-reinforcer relationships of traditional Pavlovian paradigms. Presumably, a correspondence exists between behavioral mass and the notion of associative strength in the associative learning literature. Although response rate has little meaning in the trialwise structure of classical (i.e., Pavlovian) conditioning, response probability or magnitude might be regarded metaphorically as velocity. Momentum theory suggests that resistance to change (e.g., extinction) is a better indicator of associative strength than is response probability or magnitude. Therefore, variables that strengthen Pavlovian learning should influence resistance to extinction of conditioned responding in a similar manner. Moreover, it is important to assess momentum theory outside of strictly operant paradigms, particularly because in clinical settings many common disorders (e.g., phobias) and their therapies (e.g., cue exposure) are thought to be classically conditioned.

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.

This article asks whether there were, in post-dictatorship Chile, limitations of the autonomy of cultural and artistic production addressing the memory of traumatic events. In particular, the article analyzes the content and history of the production of some relevant sections of the mural painting Memoria Visual de una Nación by the Chilean artist Mario Toral. The article demonstrates that public art was an arena of struggle for the meaning of democracy during the postdictatorship period. To do this, he uses concepts (...) from post-structuralist political theory, cultural studies, the philosophy of memory, and memory studies. The article also offers an interpretation of cultural production as an open and contingent process. It concludes that the transition via transaction in Chile had a negative influence on the field of artistic production, reducing its autonomy and divergence from the dominant political discourse in the period.

Al definir “suicidio”, la Real Academia Española toma una opción filosófica que se aleja de algunos propósitos y puntos de vista de la salubridad pública, y acentúa su carácter de actividad íntima que realiza un sujeto capaz de acción. Los límites del concepto no son claros; hay un continuo entre el suicidio y encontrar la muerte por causa natural, accidental o conducta de riesgo. Pero el suicidio solo puede ser fruto de un acto soberano, de modo que quien esté privado (...) de voluntad no es un suicida. Esto permite discutir los planteamientos de B. Spinoza e I. Kant, así como algunas posturas de sanidad pública que no ven ese carácter soberano del suicidio. (shrink)

Resumen: Este artículo analiza cómo se encadenan los planos de lo ontológico y lo óntico en la Teoría Política del Discurso de Ernesto Laclau. Se concluye que, desde el plano ontológico, la hegemonía constituye una forma político-discursiva de articulación y universalización relativa, precaria, contingente y parcial de los particularismos en significantes vacíos que actúan como puntos nodales. Desde el nivel fenoménico-político, Laclau pone en juego estos conceptos para mostrar el desplazamiento y contaminación discursiva entre lo particular y lo universal en (...) la operación hegemónica, que transforma las identidades políticas y construye un orden comunitario y un nuevo sentido común. Desde el nivel ético-político, la conceptualización de la hegemonía se articula a la construcción discursiva de una estrategia socialista y a una democracia radical. Este proyecto político lucha contra los esencialismos y las formas de explotación y opresión social y por un horizonte de liberación que amalgame las luchas de los grupos subordinados y reconozca las diferencias y particularidades como constitutivas y deseables. La teoría formal del populismo presenta algunas inconsistencias óntico-ontológicas en este esquema. Sin embargo, su sobredeterminación simbólica disuelve las disyunciones tajantes entre la lógica y el análisis histórico-político y entre la forma y el contenido. Ello pone de manifiesto el mutuo anudamiento entre lo óntico y lo ontológico y la centralidad de la noción gramsciana de hegemonía para el análisis político y crítico de fenómenos y procesos históricos contemporáneos.: This article analyzes how the ontological and ontic planes are interconnected in Laclau’s political discourse theory. It is concluded that, on the ontological level, hegemony constitutes a political-discursive form of relative, precarious, contingent and partial universalization and articulation of particularities in empty signifiers that act as nodal points. On the phenomenological-political level, Laclau shows the displacement and discursive contamination between the particular and the universal in the hegemonic operation which transforms political identities and builds a communitarian order and a new commonality. On the ethical-political level, the conceptualization of hegemony is articulated as the discursive construction of a socialist strategy and a radical democracy. This political project fights against essentialisms and forms of exploitation and social oppression of subordinate groups, and in favor of a horizon of liberation that recognizes conflicts and differences as constitutive and desirable. The formal theory of populism presents some ontic-ontological inconsistencies in this scheme. However, its symbolic overdetermination dissolves the disjunctions between logic and historical-political analysis and between form and content. This reveals the mutual interconnection between the ontic and the ontological, and the central relevance of the Gramscian notion of hegemony for the political and critical analysis of contemporary historical phenomena and processes.

This paper compares Cassirer´s and Bohr´s views on symbolic knowledge in quantum physics. Although both of them consider quantum physics as symbolic knowledge, for Cassirer this amounts to a complete renunciation to intuition in quantum physics, while according to Bohr only spatio-temporal images may provide the mathematical formalism of the theory with physical reference. We show the Kantian roots of Bohr´s position and we claim that his Kantian concept of symbol enables Bohr to account for the sensible content of quantum (...) theory as well as for its systematic relation to classical physics.

The present paper deals with the notion of complementarity associated with Salmon’s proposal of peaceful coexistence between scientific explanation models. The relation between the coexistence of such models and theoretical reduction is studied. Finally a way of understanding peaceful coexistence is proposed which does not rely on pragmatic factors and also allows us to return to the use of the explanatory capacity of theories as a value of relevance in the rational choice between scientific theories.

La epistemología histórico-filosófica de la "visión de los vencidos" suponía la existencia de una verdad, complementaria a la del vencedor. Sin embargo, esa perspectiva conduce, sin proponérselo, a un debilitamiento de la idea de verdad en relación con el continente americano. Eso abre la puerta a la desrealización de éste, evolucionando hacia la idea de que América es un juego de lenguaje dentro de otros juegos de lenguaje, sin remitir a una realidad o a una verdad epistemológico-filosófica. El análisis de (...) algunos aspectos de la obra de Miguel León Portilla, Peter Mason, Peter Sloterdijk y de la Jornada de Omagua de Dorado, escrita en 1561, sirven de apoyo para lo aquí planteado. The historical-philosophical epistemology of the vision of the vanquished supposed the existence of a true, complementary to the defeated's one, in all discourse on America. Nevertheless, that perspective leads, unwillingly, to a weakening of the idea of truth in relation to the continent. This opens the path to its derealisation and leads to the idea that America is a speech game within another speech games, and does not address a reality or a philosophical-epistemological truth. Our statements are supported by analysis of some aspects of the work of Peter Sloterdijk and Peter Mason and of the Journey of Omagua y Dorado, written in 1561. (shrink)

Se investigan las condiciones que la doctrina de Kant establece para la predicación de la realidad efectiva de objetos empíricos determinados. Se sostiene: a) que para tal predicación no solo es necesario que haya percepción, sino que también se requiere cierta homogeneidad de los datos sensibles y b) que el conocimiento de la existencia de objetos empíricos determinados depende de la aplicación de principios regulativos de la experiencia.
