Resumen de La teoría pragmática de la vaguedad: problemas y perspectivas

Por • 18 feb, 2018 • Category: Crítica

Los dos grandes problemas del enfoque supervaluacionista para la vaguedad son determinar cuáles son las precisificaciones admisibles y la vaguedad de orden superior ilimitado. Apelando al uso de los términos vagos por lo comunidad lingüística competente puede dividirse de forma tajante la extensión de un término precisando en que casos se aplica definidamente, en cuáles se aplica indefinidamente y en cuales es indeterminado si se aplica. Esto produce dos órdenes de vaguedad, con lo que se bloquean los argumentos sorites. Finalmente se indaga qué semántica resulta más adecuada para una vaguedad de segundo orden. La vaguedad se basa en una indeterminación determinada en la aplicación de ciertos términos por parte de los hablantes nativos.



The Heuristic Function of Duality

Por • 9 feb, 2018 • Category: Crítica

I conceptualise the role of dualities in quantum gravity, in terms of their functions for theory construction. I distinguish between two functions of duality in physical practice: namely, discovering and describing ‘equivalent physics’, vs. suggesting ‘new physics’. I dub these the ‘theoretical’ vs. the ‘heuristic’ functions of dualities. The distinction seems to have gone largely unnoticed in the philosophical literature: and it exists both for dualities, and for the more general relation of theoretical equivalence.



Hegel, Deleuze and the critique of representation

Por • 5 feb, 2018 • Category: Crítica

Gilles Deleuze is now considered to be one of the most important continental philosophers of the twentieth century. Deleuze’s philosophy marked a radical break with the dominant postwar phenomenological tradition in France and a return to metaphysics, albeit a ‘metaphysics of difference’. One of the key influences on the direction of Deleuze’s philosophy is his attempt to avoid what he calls the ‘philosophy of identity’ or ‘representation,’ which he sees as culminating in the absolute idealism of the nineteenth-century German philosopher G. W. F. Hegel. Deleuze argues that Hegel’s philosophy completes the philosophy of identity, which can be traced back to Aristotle. He claims that the privileging of identity leads to certain fundamental structural difficulties in the history of philosophy. Deleuze’s claim that he wrote in an atmosphere of “generalised anti-Hegelianism” (DR, xix) makes clear the centrality of Hegel for Deleuze’s own project, but the vehemence of his rejection of Hegelian dialectic often occludes the affinities between them.



Empirical Identity as an Indicator of Theory Choice

Por • 28 ene, 2018 • Category: Crítica

There are many theories about theory choice in philosophy of science, but no any indicator of scientific theory has been precisely defined, let alone a united index system. By the example of empirical identity, I shall show that a range of scientific indicators to decide theory choice can be precisely defined by some basic concepts. I think that these indicators can provide us a better description of the principles of philosophy of science. The certain pursuit of theories’ empirical identity and novelty leads the cumulative view of scientific progress; under non-cumulative circumstance, it is totally practicable to judge a theory’s empirical identity as well as empirical novelty; empirical identity underdetermines the acceptance of a particular theory. It is possible that all the principles of philosophy of science could be explained again through the system of index of theory choice, thus a more rigorous theory of philosophy of science could be established.



Philosophy of Conceptual Network

Por • 22 ene, 2018 • Category: Crítica

The article formulates the philosophy of a conceptual network and defines a concept as a unit of meaning. According to the proposed idea, the substance of our mind (subjective psyche) is constituted by a conceptual network which is composed of continuous concepts which have meanings through connotation. The conceptual network is an epiphenomenon of the neural network that is based on a dynamic structure of a complex of neurons interconnected in a functional way. Language is a secondary phenomenon in relation to the conceptual network: the words of language correspond to the best-distinguished concepts, and their meaning is determined by their conceptual “lining”. The conceptual networks of logic, mathematics and, especially, philosophy are not perfectly determined and specified. The “Absolute Truth” not only does not exist, but in fact it does not have any sense. (Self-)consciousness emerged as a result of recurrent self-reference of the neural/conceptual network.

We establish fun parallels between coin-weighing puzzles and knights-and-knaves puzzles.



Mysterious Properties of the Point at Infinity

Por • 9 ene, 2018 • Category: Crítica

From the viewpoints of the division by zero 1/0=0/0=z/0=0 and the division by zero calculus, we will examine the mysterious properties of the point at infinity in the sense of the Alexandroff one compactification of the complex plane which is realized by the stereographic projection.



Arithmetic Gauge Theory: A Brief Introduction

Por • 25 dic, 2017 • Category: Crítica

Much of arithmetic geometry is concerned with the study of principal bundles. They occur prominently in the arithmetic of elliptic curves and, more recently, in the study of the Diophantine geometry of curves of higher genus. In particular, the geometry of moduli spaces of principal bundles appears to be closely related to an effective version of Faltings’s theorem on finiteness of rational points on curves of genus at least 2. The study of arithmetic principal bundles includes the study of {em Galois representations}, the structures linking motives to automorphic forms according to the Langlands programme. In this article, we give a brief introduction to the arithmetic geometry of principal bundles with emphasis on some elementary analogies between arithmetic moduli spaces and the constructions of quantum field theory.



La noción de “hybris” en el Critias de Platón

Por • 3 dic, 2017 • Category: Crítica

Se justifican tres tesis. Primera, el sentido mítico-religioso tradicional de la justicia como castigo de la [palabra en griego] quedó desacreditado durante la Guerra del Peloponeso, como bien lo muestra Tucídides. Segunda, en tiempos de Aristóteles, tal sentido ya habría desaparecido en favor de un nuevo paradigma basado en el concepto de [palabra en griego]. Tercera, la obra de Platón constituye uno de los últimos intentos de recuperar ese sentido mítico-religioso tradicional tratando de interpretar la Guerra del Peloponeso a través del mecanismo del castigo de la [palabra en griego]



La lógica de Hegel y la totalidad emergente

Por • 28 nov, 2017 • Category: Crítica

Este artículo expone la categoría de totalidad en la Ciencia de la Lógica de Hegel. Su estrategia discursiva consiste en exponer la clave de bóveda del idealismo hegeliano: la identidad entre el ser y el pensar que, a diferencia de San Anselmo es una construcción histórico-cultural cuyo protagonista es el sujeto.
