La variedad de metodologías científicas dedicadas a obtener conocimiento, generar creencias y motivarla acción es amplia. La filosofía de la ciencia y de la educación ha valorado críticamente las virtudes de los diversos métodos científicos, en especial de los inductivos y deductivos. Sin embargo, la aparición de nuevos procedimientos vinculados a ciencias no académicas ha promovido el desarrollo de nuevas perspectivas reflexivas que analicen dichas virtudes. Desde los métodos controlados aleatorios hasta los procedimientosepidemiológicos o clínicos, la filosofía ha examinado las (...) virtudes y también los defectos de su puesta en práctica. El presente artículo asume que la modelación basada en evidencias empíricas es una práctica de alto interés en linguistica. Con el fin de sustanciar tal asunción, se comparan dos enfoques filosóficos de la modelación científicadistinguidos por sus respectivas líneas de investigación en torno a la noción de representación: el representacionaly el pragmático. Los enfoques se ilustran posteriormente con un caso de la linguística denominado análisissintáctico del lenguaje, dirigido a examinar muestras particulares recogidas como evidencias en fases iniciales de la modelación experimental. Como conclusión, se enfatiza que ambos enfoques filosóficos aportan elementosanalíticos realmente pertinentes para el tipo de razonamiento científico que pivota en torno a modelos y cuyo alcance en la enseñanza de las ciencias puede resultar de gran interés práctico.

El texto presenta una crítica moderada al excesivo valor pedagógico concedido actualmente a las tecnologías digitales para la enseñanza online. A partir de la sospecha vertida por Andrew Feenberg sobre las bondades supuestas del papel de Internet en la enseñanza superior, se presenta un análisis de la aplicación de las nuevas tecnologías a la educación no presencial y a un tipo particular de problema tecno-epistémico que puede derivar en una disminución cualitativa de la enseñanza en las aulas. Frente a ello, (...) se proponen algunas opciones de mejora y se concluye con un enfoque crítico relativizado que, junto con el reconocimiento de la valía de ciertas tecnologías para las enseñanzas no presenciales, asuma el valor inherente de ciertos elementos tradicionales que no deben ser desmerecidos por intereses económicos ni por tendencias pasajeras.

La crítica contundente de Quine a las nociones intensionales, así como a todo lo superfluo para una ontología de raíz lógica de primer orden, le condujo a rechazar la validez de la noción de semejanza en el ámbito de las ciencias maduras . El artículo consiste preci-samente en responder a esta crítica desde una perspectiva no formalista en la que la ciencia no se reduce a simple teoría, sino que se comprende como un complejo interactivo de diversas prácticas . Mi (...) respuesta a Quine toma como eje fundamental el análisis de la semejanza en una ciencia madura como lo es la química, y presenta un estudio de caso en el ámbito de la química sintética. El objetivo del artí-culo es en tal sentido triple: por un lado, critico la concepción reductivis-ta quineana de la ciencia; por otro, reclamo la importancia de la semejan-za en química; y, por último, reivindico lo que denomino pragmatismo ex-perimental, un modo de análisis de la tecnociencia que tiene en cuenta la práctica real de ésta y la interacción teoría-experimento-prácticas científicas des-de una perspectiva naturalista. El título incluye el verbo “desquinear”, in-existente en español, en clara referencia a mi negativa de aceptar el análi-sis de Quine.Quine's strong criticism of intensional notions as well as of everything that is superfluous for an ontology based on first order logic led him to deny the legitimacy of the notion of similarity in the realm of the mature sciences . In this paper I try to refute Quine's view by adopting a non-formalistic perspective, i.e., a perspec-tive in which science is not simply reduced to a theory, but is rather seen as an interative complex of several different forms of scientific practices . My reply to Quine has as main pillar the analysis of the notion of similarity in a mature science like chemistry, and is based on a study of a concrete case in the realm of synthetic chemistry. The aim of this paper is, therefore, threefold: first, I shall criticize Quine's reductivism regarding science; second, I shall defend the centrality of the notion of similarity in chemistry; fi-nally, I shall defend what I call experimental pragmatism, i.e., a specific way of analysing technological sciences that takes into account both the actual scientific practice and the interaction between theory, ex-periment and practices from a naturalistic point of view. The title con-tains the verb "de-quining", which does not actually exist in Spanish, but clearly refers to my rejection of Quine's analysis. (shrink)

The popular notion of bullshit and the term that expresses it has received little philosophical attention despite the fact that it pervades much of human discourse. Frankfurt recovered bullshit analysis in the eighties and opened the way to studies on its nature and function. Our interest in bullshit is philosophically analytical, but also practical, as bullshit particularly affects the field of science policy. In order to understand that double character, we first present Grice’s model of meaning of expressions and then (...) summarize the controversy between the tobacco industry and the US Administration, which allows us to state our basic hypothesis: tobacco companies have developed and implemented a discursive tactic of bullshit in order to delay or avoid governmental regulations and decisions. Before eventually applying the Gricean model to various cases of bullshit, we locate our approach against the background of the comparison between sound and junk science. Keywords: Grice, intention, meaning, tobacco industry, bullshit, junk science, uncertainty. (shrink)

Resumen En este artículo propongo un análisis crítico de varias tendencias filosóficas contrarias al uso de la noción de verdad en el ámbito epistemológico, especialmente la de Rorty. En particular, sostengo que la verdad es un concepto clave para el estudio del conocimiento, especialmente el científico, en cuanto toma una forma concisa en los procedimientos experimentales de carácter probatorio-empírico. Gracias a este enfoque, busco socavar varias tesis de los enfoques de la ‘posverdad’ por medio del uso de un conjunto de (...) procedimientos científicos de obtención de evidencias en varios campos vinculados a la disciplina práctica de la medicina.In thispaper, I present a critical analysis of several philosophical tendencies that go against the use of the notion of truth in epistemology, especially Rorty’s one. Particularly, I claim that truth is a key conceptfor the study of knowledge, especially the scientific knowledge, as it takes a concise form through the experimentalprocedures for eliciting evidences. With the help of this analysis, I seek to undermine some ‘post-truth’ theses by means of analyying some scientific procedures to get evidences in severalfields related to the practical discipline of medicine.

The article focuses on some discursive defects that influence on decision-making around issues of science and technology (technoscience). Particularly, the nature and use of the linguistic phenomenon known as bullshit are analysed, and the results of this analysis are placed into the general context of the controversy about climate change. The conclusion emphasizes the relevance of avoiding confusions and humbug in the information available to the public and linked to decisions in the realm of science policy or regulation.

Resumen En el texto se expone un proceso de modelación basado en dos consideraciones (Sec. 2): que los modelos son autónomos y que sus metas directas son al menos tres: estar bien construidos, adecuarse al mundo empírico y ser capaces de realizar tareas subrogatorias. Para ello, se esbozan varios ingredientes fundamentales de la tarea modeladora en la lingüística basada en evidencias, así como los de un marco formal elegido para representar aquellos. La tercera sección está dedicada a aplicar el presente (...) análisis al caso de las redes complejas con el fin de que conceptos clave como la validez, la fiabilidad y la replicabilidad de la modelación, así como el concepto de diseño experimental en RC, se puedan observar desde un prisma representacional. La sección cuarta refleja las capacidades aplicativas de (RC), especialmente en el caso del aprendizaje del lenguaje en casos atípicos y a menudo socialmente marginados. A modo de cierre, la conclusión resume la puesta en práctica de la herramienta RC. Abstract A modeling process is initially outlined based on two considerations (Sec. 2), namely that models themselves are autonomous and that their direct goals are at least threefold: to be well constructed, to fit the empirical world, and to be able to perform subrogative tasks. This section outlines the fundamental elements of the modeling task in evidence-based linguistics, as well as those of a formal framework chosen to represent the former. The third section is devoted to applying the present theoretical analysis to the case of complex networks (CN), so that key concepts such as validity, reliability and replicability of modeling, as well as the concept of experimental design in complex networks, can be viewed from a representational perspective. The fourth section reflects the application capabilities of CN, especially in the case of language learning in atypical and often socially marginalized cases. Finally, the conclusion summarizes the implementation of the CN-tool. (shrink)

En el texto defendemos que la crítica de Byung-Chul Han a la sociedad actual en sus vertientes epistémica y tecnocientífica es una pseudo-crítica. Su crítica de la noción de transparencia se teje con citas y reflexiones de naturaleza poco clara que chocan de frente con nuestra concepción de lo que es la crítica filosófica. Como alternativa, proponemos una crítica argumentada de los mismos fenómenos a los que apunta Han con el fin de desmontar su propuesta al respecto. Sobre el trasfondo (...) de la filosofía racionalista crítica de Popper y de la semiótica crítica de Eco, proponemos escrutar las nociones de conocimiento, enseñanza y tecnologías a partir del análisis de varios conceptos clave: el pseudo-conocimiento, la posverdad y el bullshit. A partir de ello, sostenemos que hay otros fenómenos (mala ciencia y mala filosofía, cámaras de eco, burbujas epistémicas) cuyo examen nos puede ayudar a acometer nuestra tarea crítica razonada de un fenómeno clave en la actualidad que Han ni siquiera ha previsto: las tecno-enseñanza online.

One of the reasons for Carnap’s (1922) analysis of space was the confounding status of many arguments around the state of the art on that topic at that time. The unsatisfactory views supplied by mathematicians, physicists and philosophers led Carnap to propose a new conception of space. His proposal, which employs the notion of intuition as a fundamental tool, fared better, but clashed with his conventionalists intentions derived from an allegedly tolerant attitude. The notion of intuition here examined allows us (...) to claim that Carnap’s target was also an objectivist epistemological program dependent on certain realistic reminiscences embodied in the notion of evidence or matter of fact (Tatbestand).

This paper argues for the theoretical and practical validity of similarity as a useful epistemological tool in scientific knowledge generation, specifically in chemistry. Classical analyses of similarity in philosophy of science do not account for the concept’s practical significance in scientific activities. We recur to examples from chemistry to counter the claim of authors like Quine or Goodman to the effect that similarity must be excluded from scientific practices . In conclusion we argue that more recent conceptualizations of the notion (...) of similarity, particularly Giere’s one, are appropriate for a philosophical analysis that considers scientific practices on equal terms with scientific theory.

Los editores de este libro han conseguido reunir algunas de las mejores firmas de lo que en la actualidad se denomina 'filosofía de la química'. Esta subdisciplina de la filosofía de la ciencia, hasta hace bien poco marginal, comienza a exigir durante la década pasada el lugar adecuado que considera se merece, pero que la falta de análisis especializados, de talante no puramente histórico, por parte de filósofos había imposibilitado. De hecho, la supremacía de los estudios acerca de la reducción (...) de la química a la física ahondó considerable—mente en la falta de interés filosófico por las cuestiones químicas. Las fugaces apariciones de artículos dedicados al tema no hacían sino confirmar la regla de la apatía por él. Muchas eran—y son—las cuestiones que, sin embargo, rodeaban, se plasmaban y podían recibir la aclaración pertinente en el mundo de la filosofía de la química. Cuestiones que, planteadas en el marco general de la filosofía de la ciencia, no siempre se adecuaban al temario de subdisciplinas como la filosofía de la biología o la filosofía de la física. Pero también cuestiones propias de la química que podían incitar a la creación de nuevas estrategias generales. Este libro recoge una serie de respuestas en tal sentido, al proponer un elenco temático que evidencia la amplitud y el interés de los problemas filosóficos que la química origina. (shrink)

Mechanistic information is used in the field of risk assessment in order to clarify two controversial methodological issues, the selection of inference guides and the definition of standards of evidence. In this paper we present an analysis of the concept of mechanistic information in risk assessment by recurring to previous philosophical analyses of mechanistic explanation. Our conclusion is that the conceptual analysis of mechanistic explanation facilitates a better characterization of the concept of mechanistic information. However, it also shows that the (...) use of this kind of information in risk assessment is heavily influenced by pragmatic factors, which have not been sufficiently taken into account in philosophical analysis. Mechanistic models are like hypothesis that have to be validated empirically. Due to their dependence on the standards of evidence, they are subject to the same pragmatic factors. Therefore, recurring to mechanistic information does not lead to closure of the methodological controversies in risk assessment. (shrink)

The present paper intends to draw the conception of language implied in the technique of word embeddings that supported the recent development of deep neural network models in computational linguistics. After a preliminary presentation of the basic functioning of elementary artificial neural networks, we introduce the motivations and capabilities of word embeddings through one of its pioneering models, word2vec. To assess the remarkable results of the latter, we inspect the nature of its underlying mechanisms, which have been characterized as the (...) implicit factorization of a word-context matrix. We then discuss the ordinary association of the “distributional hypothesis” with a “use theory of meaning,” often justifying the theoretical basis of word embeddings, and contrast them to the theory of meaning stemming from those mechanisms through the lens of matrix models (such as vector space models and distributional semantic models). Finally, we trace back the principles of their possible consistency through Harris’s original distributionalism up to the structuralist conception of language of Saussure and Hjelmslev. Other than giving access to the technical literature and state of the art in the field of natural language processing to non-specialist readers, the paper seeks to reveal the conceptual and philosophical stakes involved in the recent application of new neural network techniques to the computational treatment of language.

Mediante el presente artículo se realiza un recorrido aproximativo a la historia de la Educación Social de forma que se conozcan los elementos que la conforman como práctica socioeducativa emergente en la última década del siglo XX y la importancia que tiene en la sociedad; de la misma forma se acomete una aproximación al proceso de profesionalización de la Educación Social a través del modelo teórico que los autores Sáez y García (2006) proponen, mediante el cual se delimitan los actores (...) que están involucrados en el proceso profesionalizador de la Educación Social y la interacción que existe entre ellos. Finalmente la cuestión que se trata es la idea de la Educación Social como elemento transformador de la ciudadanía a través de la participación, que propicia el cambio de actitudes y motivaciones en los individuos.

En contraste d’avec la pensée de Spinoza, pour qui la foi n’est qu’un phénomène extérieur et étrange, une notable exception à sa théorie du salut par le control des passions et l’amour intellectuelle à Dieu et par Dieu que l’homme de connaissance peut atteindre seulement grâce à la véritable philosophie, on analyse ici très brièvement la compréhension que de la foi nous proposent, en ayant l’expérience intérieure, surtout Descartes mais aussi Pascal. Pour le premier la foi relève de la volonté, (...) à qui la grâce incline d’embrasser le message révélé à peu près comme la perception claire et distincte incline au jugement dans l’acte deconnaissance. Pour Pascal la foi et la connaissance sont de l’ordre, toutes deux, du coeur, qui comme on sait a des raisons que la raison ne connait pas. (shrink)

The biogeographic contributions of Léon Croizat (1894–1982) and the conflictive relationships with his intellectual descendants and critics are analysed. Croizat’s panbiogeography assumed that vicariance is the most important biogeographic process and that dispersal does not contribute to biogeographic patterns. Dispersalist biogeographers criticized or avoided mentioning panbiogeography, especially in the context of the “hardening” of the Modern Synthesis. Researchers at the American Museum of Natural History associated panbiogeography with Hennig’s phylogenetic systematics, creating cladistic biogeography. On the other hand, a group of (...) New Zealand biologists formalized Croizat’s original concepts and soon began arguing with cladistic biogeographers over the relative merits of their approaches. In Latin America, panbiogeography and cladistic biogeography were incorporated as parts of an integrative approach. A recent development, molecular panbiogeography, is based on the use of molecular phylogenetic data. The current practice shows that some authors insist on considering panbiogeography as the only appropriate approach and vicariance as the only relevant process, whereas others accept Croizat’s dictum “Earth and life evolve together” as a useful guide to understanding broad, general patterns, but recognize that dispersal also contributes substantially to biotic assembly. The framework of integrative pluralism allows to explain the complexities of the biogeographic processes involved in biotic assembly without the need of unification on a large scale. This historical analysis intersects with the existing historiography of the Modern Synthesis and may provide some insights on the dynamics of integrative pluralism, which may be especially relevant in the current development of the Extended Synthesis.

Ecological psychology (EP) and the enactive approach (EA) may benefit from a more focused view of lived temporality and the underlying temporal multiscalar nature of human living. We propose multiscalar temporality (MT) as a framework that complements EP and EA, and moves beyond their current conceptualisation of timescales and inter-scale relationships in organism-environment dynamical systems. MT brings into focus the wide ranging and meshwork-like interdependencies at play in human living and the questions concerning how agents are intimately entangled in such (...) meshworks, utilising them as resources for skilful living. We develop a conceptual toolkit that highlights temporality: Firstly, we address lived temporality. We use a case study from psychotherapy to show how a person’s skilful engagement with the world is best described as adaptive harnessing of interdependencies of constraints residing across a wide range of timescales. We call this skill time-ranging. Secondly, the case study provides a proof of concept of the integration of an idiographic approach to human conversing and a more general theory of emergent organisation rooted in theoretical biology. We introduce the existing concept of constraint closure from theoretical biology and scale it up to human interactivity. The detailed conceptualisation of constraint interdependencies constitutes the backbone of the proposal. Thirdly, we present a heuristic mapping of what we call organising frames. The mapping guides the conceptualisation of the emergence of inter-scale relationships and serves as an epistemic tool that brings together nomothetic and idiographic approaches. Finally, we combine new ideas with re-interpretations of existing EP and EA concepts and elaborate on the need of a fresh new look at the implicit and sometimes missing conceptualisations of temporality in the EP and EA literature.

The most documented juridical studies about hispanic woman in the late Middle Ages, belong to three specialities: political law, civil or common law (matrimonial), and criminal law. It is in the sphere of matrimonial law where the influence of christian principles has been described as prominent, contributing to the juridical conjugal parity, thus recognizing woman a full civil capability.

The paper critically examines Bobbio's famous disctinction between legal positivism as a method, a theory and an ideology. The author first highlights certain problems of the distinction itself and then focuses on Bobbio's self-determined position within it. Delving on Bobbio's analysis of the concepts of basic norm and rule of recognition, he demonstrates how Bobbio's later rejection of these two concepts implies acceptance of positivistic legal theory and ideology – despite the fact that he explicitly rejected them in the first (...) place. The reason for this Bobbio's slip is found in his absorbtion in the positivist legal culture which is permeated with the internal point of view on the law. The author suggests rejecting Bobbio's tripartite disctinction of legal positivism and proposes instead to view this as a set of seldom indvisible standpoints forming a specific legal culture.
