En este artículo postulamos que el trabajo de Kuhn es una revolución filosófica para la filosofía de la ciencia. La búsqueda de revoluciones filosóficas es una extensión de las ideas de Kuhn acerca de las revoluciones científicas. Las revoluciones filosóficas se distinguen de las revoluciones científicas en algunos aspectos que discutimos en este trabajo. Defendemos que la revolución kuhniana consiste en la naturalización de la filosofía de la ciencia que se desprende de sus trabajos y discutimos la analogía biológica que (...) Kuhn empleó como un ejemplo ilustrativo. (shrink)

The phenomenon of size constancy is defined as the apparent perceptual invariance of the linear dimensions of a seen object as this approaches the eye or recedes from it. It has been interpreted as resulting from the application by the brain of a size correction, made possible by the subject's apprehension of distance cues present in the image. We present several observations which, by dissociating accommodation from distance of the seen object and by suppressing the optic effects of accommodation on (...) the visual image itself, show that this interpretation is incorrect, and that in fact the size correction of the visual image is a function of the central effort of accommodation, not of the distance of the seen object.

Two experiments compared “Red-Green” dichromats’ empirical and metacognized capacities to discriminate basic color categories and to use the corresponding basic color terms. A first experiment used a 102-related-colors set for a pointing task to identify all the stimuli that could be named with each BCT by each R-G dichromat type. In a second experiment, a group of R-G dichromats estimated their difficulty discriminating BCCs-BCTs in a verbal task. The strong coincidences between the results derived from the pointing and the verbal (...) tasks indicated that R-G dichromats have very accurate metacognition about their capacities and limitations in the use of BCTs. Multidimensional scaling solutions derived from both tasks were very similar: BCTs in R-G dichromats were properly represented in 2D MDS solutions that clearly show one chromatic dimension and one achromatic dimension. Important concordances were found between protanopes and deuteranopes. None of these dichromats showed substantial difficulty discriminating the Red-Green pair. So, to name them “R-G” dichromats is misleading considering their empirical capacities and their metacognition. Further reasons to propose the use of the alternative denomination “Brown-Green” dichromats are also discussed. We found some relevant differences between the “Brown-Green” dichromats’ empirical and self-reported difficulties using BCTs. Their metacognition can be considered a “caricature” of their practical difficulties. This caricature omits some difficulties including their problems differentiating “white” and “black” from other BCTs, while they overestimate their limitations in differentiating the most difficult pairs. Individual differences scaling analyses indicated that the metacognition regarding the use of BCTs in “Brown-Green” dichromats, especially deuteranopes, is driven slightly more by the chromatic dimension and driven slightly less by the achromatic dimension, than their practical use of BCTs. We discuss the relevance of our results in the framework of the debate between the linguistic relativity hypothesis and the universal evolution theories. (shrink)

Este artigo apresenta o projeto de G. Vico para o estabelecimento da ciência moral. Vico esteve empenhado na emancipação do estudo das manifestações objetivas do espírito por intermédio da reforma do racionalismo cartesiano. A crítica ao iluminismo é feita com a retomada do conceito de barbárie no âmbito da filosofia, contrapondo-o ao conceito de esclarecimento do Século das Luzes.

La importancia de las ciencias naturales para la vida y el pensamiento contemporáneos es reconocida ampliamente. En ética y metaética la relevancia de las ciencias naturales se encuentra estrechamente vinculada con la concepción conocida como Naturalismo ético. A pesar de que existe una vasta literatura sobre Naturalismo y Naturalismo ético no es fácil encontrar un libro que recopile lo que diferentes autores relevantes tiene para decir sobre tal tópico. El libro Ethical Naturalism. Current Debates (2012) ha venido a llenar tal (...) laguna. Este trabajo presenta el tema general del libro y analiza y critica algunas de las ideas allí desarrolladas. El propósito central es hacer algunas observaciones generales a la empresa del Naturalismo ético considerado globalmente y al mismo tiempo algunas observaciones que son relevantes sólo para algunas de las intervenciones que forman parte de la colección.

The book, volume 42 in the Boston Studies in the Philosophy of Science, consists principally of two interconnected essays in theoretical biology. The first, entitled "Biology of Cognition," was written in 1969 by Humberto R. Maturana, a Chilean neurophysiologist and anatomist whose earlier work included studies of vision in birds and the frog. The second essay, "Autopoiesis: the Organization of the Living," is an expansion of certain sections in the first and was written in 1972 by Maturana and Francisco (...) J. Varela, a philosophical biologist. Although Maturana alone is responsible for the introduction, the two essays are said to represent one point of view, expressed in the concept of "autopoiesis." The term, "a word without a history," was invented to convey "the central feature of the organization of the living, which is autonomy". Autopoiesis, it is claimed, enables us to say at once, through the logic of a self-referring homeostatic system, what is organic life and cognition. "Living systems are cognitive systems, and living as a process is a process of cognition". (shrink)

"Aranguren: filosofía en la vida y vida en la filosofía" llevó por nombre la exposición sobre la figura y el legado de José Luis L. Aranguren (Ávila 1909- Madrid 1996) que pudo verse desde el 4 de junio al 26 de julio de 2009 en el Pabellón Transatlántico de la Residencia de Estudiantes de Madrid con ocasión del centenario del nacimiento del filósofo abulense.

Grace A. de Laguna was an American philosopher of exceptional originality. Many of the arguments and positions she developed during the early decades of the twentieth century later came to be central to analytic philosophy. These arguments and positions included, even before 1930, a critique of the analytic-synthetic distinction, a private language argument, a critique of type physicalism, a functionalist theory of mind, a critique of scientific reductionism, a methodology of research programs in science and more. Nevertheless, de (...) class='Hi'>Laguna identified herself as a defender of the speculative vision of philosophy, a vision which, in her words, “analytic philosophy condemns.” I outline her speculative vision of philosophy as well as what is, in effect, an argument she offers against analytic philosophy. This is an argument against the view that key parts of established opinion, e.g., our best theoretical physics or most certain common sense, should be assumed to be true in order to answer philosophical questions. I go on to bring out the implications of her argument for the approaches to philosophy of Bertrand Russell, Willard V. Quine and David Lewis, and I also compare the argument to recent, related arguments against analytic philosophy. I will suggest that de Laguna offers a viable critique of analytic philosophy and an alternative approach to philosophy that meets this critique. (shrink)

This essay is part of a special issue celebrating 50 years of Political Theory. The ambition of the editors was to mark this half century not with a retrospective but with a confabulation of futures. Contributors were asked: What will political theory look and sound like in the next century and beyond? What claims might political theorists or their descendants be making in ten, twenty-five, fifty, a hundred years’ time? How might they vindicate those claims in their future contexts? How (...) will the consistent concerns of political theorists evolve into the questions critical for people decades or centuries from now? What new problems will engage the political theorists (or their rough equivalents) of the future? What forms might those take? What follows is one of the many confabulations published in response to these queries. (shrink)

"Knowing how we know" is the subject of this book. Its authors present a new view of cognition that has important social and ethical implications, for, they assert, the only world we humans can have is the one we create together through the actions of our coexistence. Written for a general audience as well as for students, scholars, and scientists and abundantly illustrated with examples from biology, linguistics, and new social and cultural phenomena, this revised edition includes a new afterword (...) by Dr. Varela, in which he discusses the effect the book has had in the years since its first publication.

En la formación inicial docente, el estudio de la epistemología constituye una pieza fundamental para que los futuros profesores puedan filosofar sobre la realidad de los diversos contextos educativos y se pregunten cómo mejorarla desde los principios que rigen la investigación científica. De este modo, gracias al sustento epistemológico, los estudiantes de pedagogía pueden formarse como docentes investigadores capaces de analizar los cambios sociales propuestos por las múltiples realidades y conocer cómo se construye el conocimiento científico de una especialidad dada. (...) La finalidad de este trabajo, es presentar una reflexión filosófica-epistemológica sobre la imperiosa necesidad de desarrollar el conocimiento epistemológico en la formación inicial del profesorado de matemática e historia, considerando los fundamentos disciplinares, pedagógicos y cognitivos de dichas áreas.

La Biodiversidad biológica implica una gran responsabilidad para el ser humano, y somos quienes debemos cuidar para que no se pierda, pero a veces no está en nuestras manos protegerla, esto debido a que se presenta la pandemia del Covid-19 y el plantel tuvo que ser abandonado. Las plantas existentes en dicho plantel se secaron o están por perderse, así mismo como los animales silvestres de la región; actualmente estamos en semáforo verde y ya se pueden cuidar las plantas regándolas (...) constantemente. Para el cuidado de la biodiversidad es necesario que toda la comunidad tanto del Municipio como los que estamos involucrados en el plantel CECYTEM Valle de Chalco Solidaridad unamos esfuerzos para preservar tanto a plantas como a animales, y que si se llegará a presentar un rebrote de la pandemia formar comisiones para el cuidado de dicha biodiversidad.

Philosophers such as Elizabeth Anscombe and Donald Davidson have explained that we cannot derive predictions from judgments such as "he boasted from vanity." Such judgments are also the source of countless painful mistakes. However, are they necessarily unreliable? Often enough, even if only gradually and partially, we get people right. Assuming that we do is already assuming that there must be a connection, if not causal then at least casual, between what a person is, what she does, and how she (...) acts; and that we may describe it correctly. If no ironclad generalizations can be made that connect the way a person is, her reasons, and her actions, how might we describe correctness in judgments such as this?Anscombe... (shrink)

En "Legal Reasons, Sources and Gaps", Raz señala que las lagunas jurídicas existen sólo cuando el derecho habla con voz incierta o cuando habla con muchas voces, pero que no hay lagunas cuando el derecho guarda silencio. En este último caso habría reglas de clausura, analíticamente verdaderas, que impiden la ocurrencia de esas lagunas. Según Raz, si hay una laguna en un sistema jurídico, entonces no es verdadero ni falso que exista una razón concluyente para ejecutar cierta acción. Así, (...) una de las contribuciones más importantes de Raz a la solución del problema de las lagunas jurídicas es subrayar que el discurso jurídico no está completamente controlado por la bivalencia. Sin embargo, a menudo se sostiene que el rechazo de la bivalencia conduce a contradicciones. Si esta afirmación fuese verdadera, entonces la solución de Raz al problema de las lagunas jurídicas se vería seriamente amenazada. En este artículo mostramos, con ayuda de una herramienta analítica sofisticada, i.e., la lógica de la verdad de G.H. von Wright, que el rechazo de la bivalencia sólo nos compromete a aceptar la conclusión trivial de que puede haber proposiciones que no son verdaderas ni falsas. Por esta razón, el trabajo de Raz todavía puede ser considerado un buen punto de partida para analizar las relaciones entre normas, razonamiento práctico y lagunas jurídicas. Sin embargo, también mostramos que para admitir proposiciones que no son verdaderas ni falsas, las tesis de Raz deben ser reformuladas. De otra manera, la tesis de que no existen lagunas cuando el derecho guarda silencio no sería compatible con el rechazo de la bivalencia. /// In his paper "Legal Reasons, Sources and Gaps", Raz says that legal gaps only exist when law speaks with uncertain voice or when it speaks with many voices, but there are no gaps when law is silent. In this later case, rules of closure, which are analytically true, prevent from the occurrence of gaps. According to Raz, if there is a gap in a legal system, then both the claim that there is a conclusive legal reason to perform a certain action, and its negation are neither true nor false. Therefore, one of the Raz's most important contributions to the solution of the problem of legal gaps is to remark that legal discourse is not altogether governed by the principie of bivalence. However, philosophers often claim that the denial of bivalence leads to a logical inconsistency. If this claim were true, then Raz's solution to the problem of gaps would be seriously threatened. In this paper we show--with the aid of a sophisticated analytical tool, i.e., von Wright's truth-logic--that the rejection of bivalence only commits us to accept the trivial conclusion that propositions can lack truth-values. For this reason, Raz's paper can still be regarded as a good starting-point for analyzing the relationships between norms, practical reasoning and legal gaps. However, we also show that in order to admit propositions which are neither true nor false, Raz's theses must be reformulated. Otherwise, the claim that there is no gap when law is silent would not be compatible with the rejection of bivalence. (shrink)

Here they are revised notions of the Western tradition that conform the discourse of poetic reason, and the way that Maria Zambrano assumed them. Her thought examines the possibilities of the words, either poetic or philosophical, to allow persons to get conscience. She attempts to unify both types of words using a notion of love as essential intent for dealing with the otherness, allowing, also, the human being conscious reflection on the affectivity. To achieve this, she revises culture to find (...) ideas and examples to support the poetic reason as loving and hopeful reflection and as a possibility of the humanity to know about its own feelings.
