In this historical article, Newton da Costa discusses Francisco Miró Quesada’s philosophical ideas about logic. He discusses the topics of reason, logic, and action in Miró Quesada’s work, and in the final section he offers his critical view. In particular, he disagrees with Miró Quesada’s stance on the historicity of reason, for whom “reason is essentially absolute”, whereas for da Costa it “is being constructed in the course of history”. Da Costa concludes by emphasizing the importance of Miró Quesada’s (...) theory of logic and reason, despite it still being incomplete. -/- Historical article by Newton da Costa, annotated and translated by J.

Uno de los propositos de Miro Quesada al escribir esta obra fue ofrecer "a todo aquel que se interese por la cultura latinoamericana en particular y sus manifestaciones filosoficas en particular -especialmente profesores y estudiantes- un libro que sirve para orientarlos en la produccion cada vez mas vasta y profusa de la filosofia latinoamericana.".

The purpose of this paper is to elucidate the semantic relation between continental drift and plate tectonics. The numerous attempts to account for this case in either Kuhnian or Lakatosian terms have been convincingly dismissed by Rachel Laudan, who nevertheless acknowledged that there was not yet a plausible alternative to explain the so called “geological revolution”. Several decades later, the epistemological side of this revolution has received much attention, while the semantic relation between drift theory and plate tectonics has remained (...) mainly unexplored. In studying this case under a new light, the notion of embedding, as distinguished from other sorts of intertheoretical relations :11–27, 2011), will have a particular significance. After formally analyzing the relationship between continental drift and plate tectonics, it will become evident that the models of drift theory are part of the models of plate tectonics, thereby fulfilling the conditions for embedding. All theoretical concepts from drift theory are presupposed in some theoretical concepts from plate tectonics, and all empirical concepts of the former are shared by the latter. Furthermore, all the successful paradigmatic applications of continental drift are also successful applications of plate tectonics. As a consequence, under the label “geological revolution”, we actually find a salient historical case of cumulative progress across theory change. (shrink)

L’objectif de ce texte est double: expliquer certaines limitations des approches traditionnelles du succès des théories, et esquisser un critère pour l’évaluation comparative des succès empiriques d’une théorie. On insiste sur les points suivants: a) la supériorité de la prédiction sur l’adaptation, b) la résolution des anomalies non-réfutantes et c) l’utilisation limitée d’hypothèses ad hoc. Après une première partie consacrée à lever les ambiguïtés de l’expression « succès d’une théorie », la deuxième partie traite de quelques-unes des principales lacunes des (...) approches conséquentialistes traditionnelles du succès des théories. Enfin, dans la dernière section, on esquisse le critère de succès empirique d’une théorie et on donne quelques éléments pour renforcer ce critère. (shrink)

This article examines how problems of validity in empirical social research differ from those in natural science. Specifically, we focus on how some ontological peculiarities of the object of study in social science bear on validity requirements. We consider these issues in experimental validity as well as in test validity because, while both fields hold large intellectual traditions, research tests or questionnaires are less closely connected to natural science methodology than experiments.

As emphasized by Larry Laudan in developing the notion of non-refuting anomalies, traditional analyses of empirical adequacy have not paid enough attention to the fact that the latter does not only depend on a theory’s empirical consequences being true but also on them corresponding to the most salient phenomena in its domain of application. The purpose of this paper is to elucidate the notion of non-refuting anomaly. To this end, I critically examine Laudan’s account and provide a criterion to determine (...) when a non-refuting anomaly can be ascribed to the applicative domain of a theory. Unless this latter issue is clarified, no proper sense can be made of non-refuting anomalies, and no argument could be opposed to those cases where an arbitrary restriction in a theory’s domain of application dramatically reduces the possibilities for its empirical scrutiny. In arguing for the importance of this notion, I show how several semanticist resources can help to reveal its crucial implications, not only for theory evaluation, but also for understanding the nature of a theory’s applicative domain.

The variations in how subjects respond to positively or negatively framed descriptions of the same issue have received attention from social science research, where, nevertheless, a naïve understanding of speech interpretation has undermined the different explanations offered. The present paper explores the semantic-pragmatic side of framing effects and provides a unifying explanation of this phenomenon in terms of a combined effect of pragmatic presuppositions and default implicatures. The paper contributes to a more comprehensive understanding of representations and cognitive processes involved (...) in the framing bias by showing how well-entrenched linguistic practices associated to frame choice, and conducive to an implicit focus, result in default implicatures on the addressee’s side.

The present work constitutes an attempt to make explicit those pragmatic norms successfully operating in empirical science. I will first comment on the initial presuppositions of the discussion, in particular, on those concerning the instrumental character of scientific practice and the nature of scientific goals. Then I will depict the moderately naturalistic frame in which, from this approach, the pragmatic norms make sense. Third, I will focus on the specificity of the pragmatic norms, making special emphasis on what I regard (...) as a key idea underlying them, namely, the view, vigorously advocated by classical pragmatists like C. S. Peirce and G. Vailati, that the best test for objectivity is the test of action. Finally, I am going to put forward a tentative list of pragmatic norms that can be abstracted from a careful observation and analysis of scientific practice as provided by current philosophers of experimentation (A. Franklin and F. Steinle among others). The norms will be divided into four classes corresponding to four aspects of science in which they rule, that is, self-correction, prediction, explanation and both experimentation and computation. In the following account, the formulation of those pragmatic norms successfully governing science will be understood as a contribution that scientifically-oriented pragmatism can make to the normative naturalistic project in epistemology.

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

The purpose of this paper is to show how the degree of experimental validity of scientific procedures is crucially involved in determining two typical pragmatic modes in science, namely, the preservation of useful procedures and the disposal of useless ideas. The term 'pragmatic' will here be used following Schurz's characterisation of being internally pragmatic, as referring to that which proves useful for scientific or epistemic goals. The first part of the paper consists in a characterisation of the notion of experimental (...) validity. The second part is focused on several historical examples illustrating how the above pragmatic modes relate to the question of experimental validity. The Michelson-Morley experiment is presented as a case of a highly valid and useful experiment preserved through the development of different theories (like, on the one hand, the ether theory, upheld by Fitzgerald and Lorentz, and, on the other hand, Einstein's special theory of relativity). The concept of caloric will be discussed as an example of an idea that was discarded once it became useless, after heat was understood as a form of energy within the new frame provided by the kinetic theory of heat towards the middle of the 19th century.

El aumento en la producción y consumo de frutas y hortalizas mínimamente procesadas de los últimos años ha con­tribuido a incrementar las toxiinfecciones alimentarias asociadas al consumo de productos vegetales frescos. Esto es debido a que los tratamientos desinfectantes llevados a cabo actualmente por industria de IV gama son insuficientes para garantizar la seguridad microbiológica de los productos finales, y además estos no reciben ningún tratamiento capaz de eliminar todos los patógenos antes de su consumo. Por lo tanto, es necesario (...) utilizar estrategias al­ternativas para reducir los microorganismos patógenos y alteran­tes en frutas y hortalizas. La bioconservación, mediante el uso de microorganismos o sus metabolitos, es una alternativa que, en combinación con las prácticas habituales, puede reducir o prevenir el crecimiento de patógenos en productos mínimamente procesa­dos, mejorando su calidad microbiológica. En este artículo se pre­sentan los resultados más relevantes sobre la bioconservación de frutas y hortalizas mínimamente procesadas. (shrink)

A la luz de consideraciones históricas, lingüísticas, filosófico-políticas ofrezco una perspectiva interpretativa del artículo 2 de la Constitución Argentina que permite un rango más amplio que el actual de lecturas plausibles. En particular, sugiero que dicha cláusula no requiere el financiamiento público de la religión católica.

En el presente trabajo es explicitan de forma sistemática las contribuciones más significativas del estructuralismo a la comprensión de las revoluciones científicas, tomando como punto de referencia inicial la caracterización kuhniana de éstas. Se elucidará, con ayuda del caso ilustrativo de la revolución geológica, un segundo sentido kuhniano de revolución científica, apenas discutido por el propio Kuhn y a menudo obviado por sus críticos. Esta forma de desarrollo teórico denominada “incrustación teórica”, aunque muy diferente de aquel característico de la ciencia (...) normal (o evolución teórica), es, no obstante, marcadamente continuo y acumulativo, en el sentido de que no conlleva el rechazo de la teoría precedente, sino su subsunción en la sucesora. Se analizará, por otra parte, el problema del alcance del holismo semántico a la luz del criterio de T-teoricidad estructuralista, e, igualmente, la cuestión del alcance de la inconmensurabilidad, atendiendo al espectro del cambio teórico revolucionario según las posibilidades de reducción ontológica aplicativa entre teorías inconmensurables.

It is an intimate experience for us to think, to understand and to perceive things as being identical to themselves, and to suppose, consequently, that things are truly “what” they are. Something is always conceived as itself. The given is given full of itself in all its modifications. For instance, I can think or perceive partially some lips, I can see them almost in their whole or in some of their aspects, or just see them disappear. But it does not (...) seem to be possible to think or to perceive a given as almost itself, as an aspect or as part of itself. It is the aim of this work to study the assumptions and conditions for the original position of sameness in experience, just as it occurs in the synthesis of the datum singular and distinct. The polarization of single tone (einstimmig) intentional rays in an αvτó already contains the aporiae peculiar to the experience of the identical, whose revelation shall lead us, on the one hand, to one of the nuclei of the analysis of passive synthesis, and, on the other hand, to point up how critical revision of the numerical or extensional model of self-identity is for the unity of meaning. Then, it will be a question of pointing out the reasons why in a phenomenology of identity, the renunciation of the phenomenological legitimacy of the αvτó as a guarantee for the different positions of identity must be observed.

This article identifies a double allusion to the tragic characters of Phaedra and Eriphyle in Amm. Marc. 14.1.3 and considers its possible meanings. In combination, these allusions evoke the double nature of the story of Eriphyle, therefore functioning as a reference to the double nature of Caesar Gallus’ depiction in Ammianus. The double allusion consequently forms part of Ammianus’ tragic style throughout Book 14. Having identified the presence of this double allusion, the article illuminates its possible meaning by connecting Ammianus’ (...) passage to the Virgilian rewriting of the description of Eriphyle in Homer.

We state and comment our recent results on the incompleteness of elementary real analysis and their relevance for the axiomatized sciences.

The study of conscious experience per se has not kept pace with the dramatic advances in PET, fMRI and other brain-scanning technologies. If anything, the standard approaches to examining the 'view from within' involve little more than cataloguing its readily accessible components. Thus the study of lived subjective experience is still at the level of Aristotelian science, leading to a widespread scepticism over the possibility of a truly scientific study of conscious experience. Drawing on a wide range of approaches -- (...) from phenomenology to meditation -- The View From Within examines the possibility of a disciplined approach to the study of subjective states. The focus is on the practical issues involved. (shrink)

The question whether ethical behavior is biologically determined may refer either to thecapacity for ethics (e.i., the proclivity to judge human actions as either right or wrong), or to the moralnorms accepted by human beings for guiding their actions. My theses are: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution.Humans exhibits ethical behavior by nature because their biological makeup determines the presence (...) of the three necessary, and jointly sufficient, conditions for ethical behavior: (i) the ability to anticipate the consequences of one's own actions; (ii) the ability to make value judgements; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequece of man's eminent intellectual abilities, which are an attribute directly promoted by natural selection.

The question whether ethical behavior is biologically determined may refer either to the capacity for ethics (i.e., the proclivity to judge human actions as either right or wrong), or to the moral norms accepted by human beings for guiding their actions. I herein propose: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution. Humans exhibit ethical behavior by nature because their biological makeup (...) determines the presence of three necessary conditions for ethical behavior: (i) the ability to anticipate the consequences of one’s own actions; (ii) the ability to make value judgments; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequence of man’s eminent intellectual abilities, which are an attribute directly promoted by natural selection. That is, morally evolved as an exaptation, not as an adaptation. Since Darwin’s time there have been evolutionists proposing that the norms of morality are derived from biological evolution. Sociobiologists represent the most recent and most subtle version of that proposal. The sociobiologists' argument is that human ethical norms are sociocultural correlates of behaviors fostered by biological evolution. I argue that such proposals are misguided and do not escape the naturalistic fallacy. The isomorphism between the behaviors promoted by natural selection and those sanctioned by moral norms exist only with respect to the consequences of the behaviors; the underlying causations are completely disparate.

José Otero Espasandín (1900-1987) was an important science popularizer in Argentina during the 1940´s, who belonged to the Misiones Pedagógicas (Educational Missions) group in Spain. This paper presents his biography and his work as a science and technology popularizer. It focused on his features, value and significance for that period.

Medical stem cell research is currently the cause of much moral controversy. Those who would confer the same moral status to embryos as we do to humans consider that harvesting such embryonic cells entails sacrificing embryos. In this paper, the author analyses critically the arguments given for such a perspective. Finally, a theory of moral status is outlined that coherently and plausibly supports the use of embryonic stem cells in therapeutic research.

Sobre el libro: El presente libro recoge las ponencias presentadas en la reunión anual del Seminario Spinoza que tuvo lugar en la Facultad de Filosofía de la UNED los días 13 y 14 de marzo de 2009, así como la presentación del cuadro de Espinosa pintado por Sorolla procedente de la Donación Simarro y perteneciente al fondo artístico de la Universidad Complutense, que tuvo lugar en El Escorial en el verano de 2008. Los trabajos se articulan en cuatro apartados: la (...) política, la ciencia, la proyección de Espinosa en la Ilustración y la iconografía de Espinosa, y sitúan a Espinosa en su siglo, destacando su carácter anómalo en relación con el resto de autores de su entorno. Espinosa no se adaptó a la crisis, sino que se esforzó por comprenderla sin ceder en sus ideales, lo que permitió que las ilusiones renacentistas se desarrollaran en la ilustración, superando el hiato de la crisis barroca.
