I will examine the first of Thomas Kuhn’s Thalheimer Lectures delivered in 1984, with the purpose of establishing a connection between Kuhn’s historiographical thought and his criticism of the traditional distinction between the context of discovery and the context of justification, or, as I call it, the DJ distinction. In order to do this, I will start by exploring the Kuhnian view of the so-called static approach in philosophy of science, taking as my main reference the work of Bacon, Descartes, (...) and foundationalist epistemology. I will continue by examining the relationship between Kuhnian historiography and the DJ distinction, comparing the first Thalheimer Lecture with other texts published by Kuhn. Finally, I will assert that Kuhn’s rejection of the DJ distinction is the result of adopting a historiographical matrix whose philosophical consequences are irreconcilable with the static approach in history and philosophy of science, for which the DJ distinction is essential.

This paper examines ‘The Natures of Conceptual Change’, the Notre Dame lectures given by Kuhn in 1980. In particular, I aim to examine the content of these lectures which was not published before. This exegetical task will shed light on the sources of the notion of taxonomy used in these lectures for the first time with the explicit philosophical purposes. It also will shed new light on Kuhn's position regarding the causal theory of reference. Reviewing these archival materials paves the (...) way for intertextual comparisons, as Kuhn included part of these lectures in the texts published later and in the book Plurality of Worlds: an Evolutionary Theory of Scientific Development. In recent years, the publication of Kuhn's archival material and the research on these texts increased in quantity and quality. Faced with this encouraging landscape, a comparative examination of the different unpublished texts is crucial to refining both our research tools on Kuhn's intellectual biography and the philosophical work inspired by his proposal.

This paper explores Thomas Kuhn’s intellectual history by examining sources that have been understudied so far: the Lowell Lectures of 1951 (The Quest for Physical Theory) and the hitherto unpublished Notre Dame Lectures of 1980. The analysis of these texts aims to reconstruct Kuhn’s development of a semantics that can account for scientific progress. This analysis will show that the alleged “linguistic turn” attributed to the author is actually a renewed interest in problems that existed well before publishing The Structure (...) of Scientific Revolutions.

En Razón, Verdad e Historia Hilary Putnam caracterizó la racionalidad informal como una alternativa que permite superar las limitaciones evidenciadas por las concepciones formalistas de la racionalidad. Se revisa inicialmente la caracterización ofrecida por Putnam y se establece que si bien Putnam niega todo principio universal de racionalidad, admite principios relativos, generales e indeterminados, que permanecen sujetos a necesidades de interrelación cognitiva con el entorno. A continuación, se muestra que los principios aceptan excepciones, y, a partir de aquí se defiende (...) y analiza la posibilidad de revisión de principios cuya negación no resulta actualmente concebible. Finalmente, se afirma que tanto exponer como preservar creencias de la controversia constituyen elementos históricos que deben ser contemplados por una concepción informal de la racionalidad. In Reason, Truth and History, Hilary Putnam characterized informal rationality as an alternative that allows to overcome limitations evidenced by the formalist conceptions of rationality. Initially, the paper reviews the characterization provided by Putnam and establishes that, while Putnam denies any universal principle of rationality, he accepts relative, general and vague principles, that remain subject to needs of cognitive interrelationship with the environment. Secondly, we show that principles make exceptions and defend the possibility of reviewing principles whose denial is currently not conceivable. Finally, we state that both expressing and maintaining beliefs of controversy are historical elements that should be contemplated by an informal conception of rationality. (shrink)

Estudios de filosofía contemporánea, lleva por título este volumen que reúne varios trabajos del Prof. Ricardo Navia, algunos publicados previamente en revistas especializadas de Brasil y Perú, otros que se editan por primera vez. No obstante tratarse de artículos independientes, la obra presenta continuidad temática en torno a problemas de teoría del conocimiento, filosofía del lenguaje y metafilosofía, especialmente centrados en la filosofía de la segunda mitad del siglo XX.

I will present a comparative analysis between Thomas Kuhn's The Copernican Revolution published in 1957 and The Structure of Scientific Revolutions published in 1962, ir order to identify divergences in the views contained in each work. I shall set forth a comparative analysis of the historiographical assumptions employed by Kuhn in each of his books. I will explore some proposals which have pointed out several discontinuities between both books, as I introduce some tools to widen this interpretative trend. I will (...) argue that although Kuhn’s work in 1957 contains some concerns and problems which anticipate his later stances, these anticipations coexist with historiographical formulations and premises which are incompatible with the core of SSR. Therefore, I will assert that Kuhn adopts different historiographical frameworks in CR and in SSR. Finally, I will conclude that these differences are expressions of Kuhn's adoption of a more externalist view in the former, and a more internalist frame in the latter. (shrink)

In this work we attempt to analyze the intra-theoretic characterization provided by Hilary Putnam and Werner Heisenberg between quantum mechanics and other theories. The first defended the idea that physical theories include macro principles that under specific definite historical conditions can be revised on the light of rival principles. Putnam will concentrate in the impact that quantum mechanics has produced in the classical image of knowledge. Heisenberg, on the other hand, develops his analysis from the notion of closed theories, assuming (...) the independence and incommensurability of physical theories. These divergences between the two authors will allow us to analyze how the disagreement in the consideration of the status of physical theories, goes deeper into more profound aspects related to the nature of knowledge and the relation between theory and world.

El problema de determinar cuál es el método de la Ciencia de la Información ha sido objeto de distintos abordajes y propuestas metodológicas. En este trabajo defendemos que dichos problemas usualmente se han planteado de manera errónea, y que su planteo no contribuye a una mejora del campo. Comenzamos con un recorrido por diferentes propuestas metodológicas, señalando el consenso existente sobre el impacto de la indagación metodológica en el status científico de la disciplina. Luego rastreamos la influencia del positivismo en (...) la metodología de la CI, sosteniendo que la concepción positivista del método científico aún sigue gobernando de forma implícita la autopercepción epistemológica de la disciplina. Finalmente ensayamos una lectura de algunos problemas metodológicos basada en la filosofía de Thomas Kuhn, enfatizando que no es la reflexión metodológica, sino el desarrollo de una tradición exitosa de resolución de problemas lo que consolida el status científico.

The present paper proposes a critical revision of the massive truth notion, in the context of Donald Davidson’s criticism to skepticism. It´s distinguished in Davidson’s work a cuantitative sense and a cualitative sense of the massive truth, asserting that the first one has been more frequently used and has had just an intuitive level of elucidation. The main problems associated to the cuantitative notion of massive truth are revised in relation to the quantification of beliefs, the detection of error on (...) a background of truth and the application of the Davidsonian methodology to non perceptual beliefs. Over this revision it is proposed the substitution of the cuantitative notion of massive truth for a cualitative notion, and are analized its advantages over eventual skeptical objections. (shrink)

En 1983 Thomas Kuhn introdujo la distinción entre interpretación y traducción, con el propósito de fortalecer la tesis de la inconmensurabilidad y responder a objeciones formuladas por Donald Davidson y Hilary Putnam. A partir de este contexto de debate, este trabajo revisa la distinción kuhniana con el objetivo de explorar las conexiones que pueden establecerse entre las teorías rivales y las comunidades científicas que las defienden. Para ello examino el papel de la traducción, la interpretación y la comunicación en el (...) cambio teórico, con el propósito de ampliar la distinción de Kuhn y ahondar en algunas consecuencias no contempladas en su planteo original. Concluyo que la distinción entre estos planos lingüísticos resulta fundamental para comprender y evaluar el alcance de las divergencias suscitadas en casos de inconmensurabilidad. (shrink)

Este trabajo discute una de las objeciones de N. Hall al análisis contrafactual de D. Lewis. Según Hall, los intentos de fortalecer el análisis contrafactual se apoyan en la aceptación de la transitividad, la localidad y el carácter intrínseco de las relaciones causales. Esto es problemático en cuanto el concepto de doble prevención evidencia tensiones entre estas tres tesis y el concepto de dependencia, central en el análisis de Lewis. Revisando uno de los ejemplos de Hall, se defiende que su (...) crítica al análisis contrafactual cumple parcialmente su objetivo en referencia a la localidad, ya que sólo una de las estructuras causales que Hall presenta acepta la dependencia y no la localidad, no tratándose de un típico caso de doble prevención. Finalmente se propone la denominación early doble prevention para los casos que aceptan la dependencia y no la localidad, y late doble prevention para los que aceptan ambas tesis. This paper discusses one of the objections made by N. Hall to D. Lewis's counterfactual analysis. According to Hall, the attempts to strengthen the counterfactual analysis are supported by the acceptance of transitivity, locality and intrinsic nature of causal relationships. This is problematic, as the concept of double prevention demonstrates the tensions existing among these three theses and the concept of dependence which is central in Lewis's analysis. By studying one of the examples given by Hall, we can sustain that his criticism to counterfactual analysis partially fulfills its goal in reference to locality, taking into account that only one of the causal structures exposed by Hall accept dependence but not locality and is not a typical example of double prevention. Finally we suggest the name of early double prevention for those cases that accept the dependency but not the locality, and late double prevention for those accepting both theses. (shrink)

The paper discusses certain discrepancies between The Copernican Revolution (1957) and The Structure of Scientific Revolutions (1962) by Thomas Kuhn. It shows that they present a different consideration of extra-scientific factors, that in the former have a higher explanatory weight. It states that in 1957 Kuhn applies a casuistical historiography, focused on the Copernican revolution, and in 1962 a structural historiography, focused on the invariable features of scientific revolutions. The paper concludes that the differences between these two works are significant (...) enough so as not to be considered an expression of the same view of science. (shrink)

Resumen: Janet Folina ha propuesto una interpretación del convencionalismo de Poincaré contraria a la que ofrecen Michael Friedman y Robert DiSalle. Ambos afirman que la propuesta de Poincaré queda refutada por la relati-vidad general pues supone una noción restrictiva de los principios a priori. Folina sostiene que el convencionalismo de Poincaré no es contradictorio con la relatividad general porque permite una noción relativizada de los princi-pios a priori. Intento mostrar que la estrategia de Folina es ineficaz porque Poincaré no puede (...) explicar el papel de la variedad de Riemann en la rela-tividad general. Concluyo que la tentativa de reconstruir el desarrollo de la relatividad general a partir de la filosofía de Poincaré puede constituir un obs-táculo para comprender la radicalidad del cambio que la relatividad generó en las relaciones entre física y geometría.: Janet Folina has proposed an interpretation of Poincaré’s conven-tionalism against Michael Friedman and Robert DiSalle. They both state that Poincaré’s proposal is refuted by general relativity, since it implies a restrictive notion of a priori principles. Folina claims that Poincaré’s conventionalism is not in conflict with general relativity because from Poincaré’s proposal it is possible to extract a relativized notion of a priori principles. I intend to show that Folina’s strategy is ineffective due to Poincaré’s inability to explain the role of Riemann manifold in general relativity. I conclude that the attempt to reconstruct the development of general relativity from Poincaré’s philosophy may be an obstacle to understanding the radical nature of the change that relativity brought to the relationship between physics and geometry.

Frecuentemente se atribuye al empirismo apelar a principios no empíricos para defender el conocimiento empírico, por ello se le ha acusado de incurrir en cierta clase de autorrefutación. Con el advenimiento del empirismo lógico, esta objeción tomó la forma de cuestionamiento al criterio empirista de significado, señalando que, al no tratarse de una proposición lógica ni empírica, no cumple con sus propias condiciones de significatividad. En este artículo pretendo mostrar que dentro del empirismo lógico se desarrollaron respuestas a estas críticas, (...) lo suficientemente consistentes como para resistir la objeción de autorrefutación. Asimismo, defiendo que la afirmación de autorrefutación del criterio empirista de significado parte de comprensión inadecuada de los niveles lingüísticos involucrados en su formulación, así como de algunos supuestos no explícitos respecto de su estatus. Empiricism has frequently been said to appeal to non-empirical principles to defend empirical knowledge, which is why it has been accused of falling into some form of self-refutation. With the advent of logical empiricism, this objection became a questioning of the empiricist criterion of meaning, noting that since it is neither a logical nor an empirical proposition, it does not fulfill its own conditions of meaningfulness. This paper intends to show that responses to this criticism, consistent enough to resist the objection of self-refutation, have been developed whithin logical empiricism. In addition, the article claims that the assertion that the empiricist criterion of meaning is self-refuting is based on an inadequate understanding of the linguistic levels involved in its formulation, as well as on some unspecified assumptions regarding its status.
