En el presente texto se realiza un análisis sobre la utilidad del método de los experimentos mentales en filosofía. Dicha utilidad se da en tanto que el experimento usado sea legítimo, esto es, que cumpla con ciertas exigencias teóricas. Sin embargo, la utilidad de tal método se ve afectada por la proliferación de experimentos mentales ilegítimos. Tomando como referencia un tipo específico de experimentos mentales ilegítimos, el texto se propone presentar una explicación al anterior fenómeno basada en la relación de (...) las nociones de conocimiento y necesidad lógica. Igualmente, se presentan dos formas posibles de evitar el recurso excesivo a experimentos mentales de poca utilidad. (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.

El presente artículo busca señalar la existencia de dos conflictos, al menos, que se presentan en Colombia. El primero es un conflicto directo mayoritariamente sufrido en zonas rurales. El segundo es un tele-conflicto. De su raíz griega es un conflicto que se vive desde lejos (tele). Este último, si bien es virtual, produce efectos reales en los sujetos con un alto poder de decisión, especialmente en zonas urbanas. Con ello se busca señalar el rol de los medios como condición de (...) posibilidad para la existencia del conflicto, pero no sólo debido al uso (abuso) que se pueda dar de ellos para la continuación del conflicto, sino por la misma manera en que es medializado. Para ello se analiza como caso empírico la refrendación de los acuerdos de paz de La Habana entre el estado colombiano y la guerrilla de las FARC-EP. Para ello se hará un análisis fenomenológico de la manera en que los medios interactúan con el sujeto. Con ello se busca observar el rol constitutivo de los medios de la experiencia humana. Con este punto como pivote, se señala la existencia de los dos conflictos previamente nombrados. (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.

RESUMEN Las tensiones y los vínculos posibles entre razón y violencia son un problema mayor para la filosofía. La obra de Eric Weil se consagra precisamente al análisis de las figuras históricas de dicha tensión, y su obra mayor, Logique de la Philosophie, desarrolla lo fundamental de dicho propósito. Se analiza la manera como Weil, desde la categoría de la acción -última categoría concreta de la filosofía-, en vínculo con las categorías precedentes (absoluto, obra, finito) y con las categorías formales (...) (sentido y sabiduría), enfrenta este desafío siempre nuevo para la filosofía. ABSTRACT The tensions and potential links between reason and violence are a significant philosophical problem. Eric Weil's systematic work, as well as his numerous articles and lectures, is dedicated to the analysis of the historical figures of such tensions. His major work, Logique de la Philosophie, develops that objective. The article analyzes how Weil faces this always new challenge for philosophy, on the basis of the category of action -the last concrete category of his philosophy-, together with the preceding categories (absolute, unmediated particular, finite) and the formal categories (meaning and wisdom). RESUMO As tensões e os vínculos possíveis entre razão e violência são um problema maior para a filosofia. A obra de Eric Weil se consagra precisamente à análise das figuras históricas dessa tensão, e sua obra maior, Logique de la Philosophie, desenvolve o fundamental desse propósito.

Revisión del libro En la cresta de la ola. Debates y definiciones en torno a la historia del tiempo presente por E. Allier Montaño, C. I. Vilchis Ortega y C. V. Ovalle (coord.).

This book explores the epistemic side of racial and sexual oppression. It elucidates how social insensitivities and imposed silences prevent members of different groups from listening to each other.

This paper defends a contextualist approach to epistemic injustice according to which instances of such injustice should be looked at as temporally extended phenomena (having developmental and historical trajectories) and socially extended phenomena (being rooted in patterns of social relations). Within this contextualist framework, credibility excesses appear as a form of undeserved epistemic privilege that is crucially relevant for matters of testimonial justice. While drawing on Miranda Fricker's proportional view of epistemic justice, I take issue with its lack of attention (...) to the role that credibility excesses play in testimonial injustices. I depart from Fricker's view of the relation between credibility excesses and credibility deficits, and I offer an alternative account of the contributions that undeserved epistemic privileges make to epistemic injustices. Then, through the detailed analysis of To kill a mockingbird, I elucidate the crucial role played by the social imaginary in creating and sustaining epistemic injustices, developing an analysis of the kind of social blindness produced by an oppressive social imaginary that establishes unjust patterns of credibility excesses and deficits.

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)

We study Hilbert spaces expanded with a unitary operator with a countable spectrum. We show that the theory of such a structure is ω -stable and admits quantifier elimination.

The first comprehensive survey of the criticisms of Leibniz's philosophical optimism in the first half of the eighteenth century, when what has been called the ‘debacle of the perfect world’ first began.

Se trata de analizar el puesto que ocupa El tema de nuestro tiempo en el conjunto de la obra de Ortega, en su camino hacia la llamada “Segunda navegación”, es decir, hacia su filosofía de madurez. Después de contextualizar el libro en la cultura europea de la época, describiendo las novedades que acontecieron en torno a 1921-23 y la situación histórica por la que atravesaba España, en plena crisis del sistema de la Restauración, se entra en el examen de los (...) conceptos nucleares “vida”, “generación”, “racionalismo”, “perspectivismo”, en torno a los cuales Ortega elabora su propuesta filosófica. Las grandes cuestiones de la cultura europea –políticas, morales, el sentido de la Historia– deben ser examinadas a la nueva luz de la razón vital, agotadas las fórmulas de la razón pura. Finalmente, se procede a una evaluación crítica del Tema. Ortega no logra renovar la idea nuclear de “vida humana” por depender aún de un enfoque naturalista y fiar la fundamentación de la razón vital a una ciencia nueva y no a una filosofía primera, como propondrá desde los cursos y textos de los años 30.

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)

The purpose of this article is to point out five aspects of Nietzschean thought that may be relevant to debates in the philosophy of science around the nature and representation of scientific knowledge. To this end, a literature review is carried out with the aim of selecting excerpts from Nietzschean works such as The Birth of Tragedy, Genealogy of Morals, The Gay Science and others that allow us to interpret Nietzsche as a philosopher of science concerned with the construction of (...) scientific knowledge about the physical reality. As a result, it is possible to identify an epistemological proposal in the Nietzschean perspective, whose objective representation of the world should point to an aesthetics of life. (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.

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.

This paper addresses a variant of the job shop scheduling problem with total tardiness minimization where task durations and due dates are uncertain. This uncertainty is modelled with intervals. Different ranking methods for intervals are considered and embedded into a genetic algorithm. A new robustness measure is proposed to compare the different ranking methods and assess their capacity to predict ‘expected delays’ of jobs. Experimental results show that dealing with uncertainty during the optimization process yields more robust solutions. A sensitivity (...) analysis also shows that the robustness of the solutions given by the solving method increases when the uncertainty grows. (shrink)

Analiza la forma en que el pensamiento baconiano -alianza entre ciencia, matemática y filosofía- se instituye en ideología de la modernidad y en referente universal de todo tipo de conocimiento. La epistemología positiva pretende la depuración del conocimiento científico, la demarcación entre la ciencia y pseudociencia, así como la apoteosis de la razón instrumental. El libro analiza algunas de las alternativas al positivismo: Lakatos, Kuhn, Habermas, además de la sociología cognitiva de la ciencia. Se propone un programa basado en la (...) recuperación del control social de la ciencia y la tecnología. (shrink)

Why do we have social norms—of fairness, cooperation, trust, property, or gender? Modern-day Humeans, as I call them, believe these norms are best accounted for in cultural evolutionary terms, as adaptive solutions to recurrent problems of social interaction. In this paper, I discuss a challenge to this “Humean Program.” Social norms involve widespread behaviors, but also distinctive psychological attitudes and dispositions. According to the challenge, Humean accounts of norms leave their psychological side unexplained. They explain, say, why we share equally, (...) but not why we disapprove of those who don’t. I defend the Humean Program against this challenge. In particular, I suggest an idea for how to extend the Program to account for the psychological side of norms. Socially adaptive behaviors aren’t just likely to emerge in a group; They are also likely to be widely taught within it. The transmission of these behaviors through instruction explains why they are associated with distinctive normative attitudes and dispositions. These attitudes play a pedagogical role in helping transmit these behaviors to children and newcomers. (shrink)

O objetivo principal deste trabalho é apresentar a distinção entre ciência e cientificismo e, com base no trabalho de van Fraassen, intitulado A imagem científica (2006), discutir sobre as circunstâncias em que o cientificismo poderia ser repudiado. O cientificismo é uma corrente de pensamento que somente considera válido um conhecimento se ele for científico. Segundo essa corrente, os procedimentos da ciência natural seriam mais especiais, uma vez que, dentre outros motivos, eles são capazes de descrever regularidades e possibilitar predições. Dessa (...) forma, o cientificismo defende que os procedimentos não científicos não possuem valor algum, pois não seriam capazes de descrever regularidades e realizar predições como fazem os procedimentos da ciência natural. Trataremos de maneira crítica essa concepção, apresentando o argumento de van Fraassen de que a descrição de uma regularidade também pode ser construída por explicações não científicas. Em sua opinião, o poder explicativo de uma teoria vai além de sua importância empírica, ele é radicalmente dependente do contexto. Isso significa que as regularidades descritas por uma crença científica são também dependentes de explicações não científicas, como as explicações da psicologia, da história, da filosofia, da sociologia, etc. Assim, a forte predição que encontramos na ciência natural não é realizada somente com base na adequação empírica e científica, mas com base em um sistema de explicações não científicas. Isso torna incorreta a classificação do conhecimento científico como o mais verdadeiro ou especial por ser capaz de descrever regularidades e realizar a predições. Pretende-se, com isso, refletir se o conhecimento pode ser construído por outras áreas não científicas, sem que o conhecimento seja com isso prejudicado. Uma reflexão necessária que servirá para apresentar um dos problemas que tornam o cientificismo indesejável. (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. Este conocimiento de sí constituye la actividad primordial de la comprensión histórica y es llevado a cabo por el individuo que comprende de acuerdo con los significados vitales y sociohistóricos de su época. 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)
