John R. Welch Singular Analogy and Quantitative Inductive Logics
abstract | view |  rights & permissions | cited by
The paper explores the handling of singular analogy in quantitative inductive logics. It concentrates on two analogical patterns coextensive with the traditional argument from analogy: perfect and imperfect analogy. Each is examined within Carnap’s λ-continuum, Carnap’s and Stegmüller’s λ-η continuum, Carnap’s Basic System, Hintikka’s α-λ continuum, and Hintikka’s and Niiniluoto’s K-dimensional system. Itis argued that these logics handle perfect analogies with ease, and that imperfect analogies, while unmanageable in some logics, are quite manageable in others. The paper concludes with a modification of the K-dimensional system that synthesizes independent proposals by Kuipers and Niiniluoto.

Enrique Alonso Ingenio e Industria. Guía de referencia sobre la Tesis de Turing-Church (Inventiveness and SkilI. Reference Guide on Church-Turing Thesis)
abstract | view |  rights & permissions | cited by
La Teoría de la Computación es un campo especialmente rico para la indagación filosófica. EI debate sobre el mecanicismo y la discusión en torno a los fundamentos de la matemática son tópicos que estan directamente asociados a la Teoria de la Computación desde su misma creación como disciplina independiente. La Tesis de Turing-Church constituye uno de los resultados mas característicos en este campo estando, además, lleno de consecuencias filosóficas. En este ensayo se ofrece una guía de referencia útil a aquellos que desean prestar alguna atención a estos asuntos y carecen de la base técnica o histórica que se precisa. En primer lugar se ofrece un resurnen de los principales problemas relacionados con la Tesis de Turing-Church para ofrecer a continuación información sobre sus aspectos más controvertidos. Se proponen algunos problemas no resueltos y se analiza su relevancia filosófica.Computer Science is a field specially rich for philosophical inquiry. Mechanism and the discussion around foundations of mathematics are topics directly asociated to Computer Science for its very constitution as an independent discipline. Church-Turing Thesis is one of the most characteristic results in this field and is plenty of philosophical consequences. In this article I offer a referenee guide useful for those who are willing to pay some attention to these matters and ignore the technical and historical basis needed for this task. I resume the main topics related to Church-Turing Thesis and give some informationabout the most controversial aspects of this subject. Some open questions are settled for further investigation paying special attention to their philosophical importance.

Ricardo F. Crespo Ciencias naturales, economía y filosofía (Natural Sciences, Economics, and Philosophy)
abstract | view |  rights & permissions | cited by
En este trabajo se postula que se pueden establecer relaciones entre las diversas ‘visiones dei mundo’ (en sentido vulgar) y las teorías economicas, a través de las epistemologías subyacentes a las mismas. Se ilustra con las siguientes relaciones: entre la cosmovisión propia dei sistema de Aristóteles y su noción de economía, entre la matriz racionalista moderna y la economía clásica y neoclásica, a través del uso de analogías físicas y biologicas, y entre algunas posturas recientes y una vision post-moderna del mundo. Se busca fomentar una actitud crítica frente a las teorías e insistir en la necesidadde buscar siempre el camino epistemológico y metodológico adecuado al objeto de estudio.This paper tries to show the bridges between world visions (in a broad sense) and economic theories, through their underlying epistemological positions. The following relations are brought up: between Aristotle’s world vision and his concept of economics, between the modern rationalist frame and classical and neoclassical economics by the postulation of analogies from physics and biology, and finally between post-modern world vision and some current perspectives. The aim of the paper is to stress on the need of maintaining a critical position toward theories and also always looking for an adequate epistemological and methodological way.

Dimitri Ginev On the Hermeneutic Alternative to Normative Naturalism
abstract | view |  rights & permissions | cited by
What I hope to do in this paper is to see whether Laudan’s normative naturalism may suggest a third alternative to normativism-naturalism dilemma in the analytical philosophy of science. In criticizing the view that all methodological rules are to be specified in the form of hypothetical imperatives, I offer the idea that a theory of scientific rationality (including its normative dimension) must go beyond the usual analytical format of “rational reconstruction”. It is precisely this idea that opens the door for a hermeneutic alternative to normative naturalism. On this alternative, one has to pay attention to the contextual normativity of doing scientific research, if one wants to give an account of the articulation of methodological rules and norms.

Oscar M. Esquisabel Perspectivas leibnizianas sobre el análisis y la síntesis (Leibnizian Perspectives on Analysis and Synthesis)
abstract | view |  rights & permissions | cited by
Los proyectos metodológicos de Leibniz nos remiten constantemente al método de análisis y síntesis. Sin embargo, un examen de las definiciones leibnizianas de los procedimientos analíticos y sintéticos muestra quc no pueden reducirse a una formulación común y que, más aún, pueden llegar a ser incompatibles. Ante csta dificultad, el presente trabajo aborda la concepción leibniziana del análisis y la síntesis desde cuatro perspectivas diferentes, a saber, la matematica, la epistémico-sintácrica, la pragmatíco-epistémica y la práctica. También expone sucintamente la manera en que evoluciona la situacion del analisis y la sintesis con relación al ars inveniendi y el ars judicardi.Leibniz’s methodological projects refer us constantly to the method of analysis and synthesis. However, an examination of the leibnizian definitions of the analytical and synthetic procedures shows that they can not be reduced to a common formation and furthermore that they can become incompatible. Faced with this difficulty, this paper approaches the Leibniz’s conception about analysis and synthesis from four different perspectives: the mathematical, the epistemic-syntactical, the pragmatic-epistemic and the practical approach. Also it exposes briefly the way in which evolves the situation of analysis and synthesis in connection with the ars inveniendi and the ars judicandi.

Luis Girela Many Simple Universes or Only a Very Complex One?
abstract | view |  rights & permissions | cited by
Through the mental experiment that I suggest, it is possiblc to demonstrate that Hugh Everett’s quantum interpretation, known as of the “many universes”, is incongruent with the special theory of relativity.
