En este trabajo se asume: que una teoría factual es un sistema conceptual para representar parcelas deI mundo; que la principal manera de expresar tales sistemas es mediante el lenguaje; y que, consecuentemente, en la comparación de teorías rivales tienen importancia los factores de índole ontosemántica. Desde esa perspectiva se analizan dos problemas que surgen de la aceptación de la tesis de la inconmensurabilidad, a saber: a) el de establecer las condiciones ontosemánticas que dan sentido a la comparabilidad de teorías inconmensurables; y b) el de la consideración de un enfoque ontosemántico compatible con el hecho de que algunas modificaciones en una teoría no conlleven variación de significado y referencia, mientras otras sí.In this work it is assumed: that a factual theory is a conceptual system for representing patches of the world; that the principal way of expressing a system of that sort is by means of language; and that, consequently, factors of ontosemantic kind are important for the comparison between rival theories. Given this perspective, two problems, whieh come up from the acceptance of the incommensurability thesis are analyzed: a) to establish the ontosemantic conditions that give sense to the comparability of incommensurable theories; and b) to consider an ontosemantic picture compatible with the fact that some modifications in a theory are not followd by variance of meaning and reference, while other modifications are.

En la estructura de una teoría se han distinguido tradicionalmente dos niveles conceptual y metodológicamente distintos: el nivel empirico y el teórico. Sostenemos que este enfoque de! doble nivel es incompleto y que conduce además a distorsiones, tanto en la comprensión filosofíca de las teorías como en la de su uso en la praxis científica. En este artículo se diseña un nuevo enfoque, segun el cual las teorías se conciben como estructuras representacionales tripartitas, que comprenden tres niveles conceptual y metodológicamente distintos: el nivel de los datos, el de los fenómenos y el de los constructos teóricos. Se exploran las relaciones estructurales básicas entre los tres niveles y se muestran algunas aplicaciones relativas a los problemas de la idealización.Traditionally two different conceptual and methodological levels are distinguished within a theory: the empirical and the theoretical level. We argue that this two-level account is incomplete, leading to distortions of the philosophical understanding of theories and their usage in scientific praxis. We sketch a new account according to which theories are conceptualizad as three-tiered representational structures comprising three conceptually and methodologically different levels, to wit, the levels of data, phenomena and the level of theoretical constructs. Basic structural relations between these differentlevels are studied, some applications concerning problems of idealization are given.

La concepción semántica en filosofía de la ciencia propuso las relaciones de isomorfismo (van Fraassen) y semejanza (Giere) para analizar las representaciones científicas. Recientemente, Ibarra y Mormann han sugerido una geometrización de la concepción representacional en filosofía de la ciencia. Este artículo afirma que es precisa una relación mas general (la de homeomorfismo) para reconstruir las representaciones científicas externas que son utilizadas en la practica científica contemporánea, y especialmente en la visualización científica digitalizada.The semantical view on philosophy of science has proposed the relationships of isomorfism (van Fraassen) and similitude (Giere) in order to analyse scientific representations. Recently, Ibarra & Mormann have suggested a geometrization of the representational view on philosophy of science. This contribution claims that a more general relationship (homeomorfism) is needed to reconstruct external representations used in contemporary scientific practice and, specially, in scientific digitalized visualization.

Este artículo pasa revista a las principales contribuciones de Víctor Sánchez de Zavala a la lingüística y a la filosofía, a traves del análisis de las ideas centrales de su pensamiento expuestas en sus libros y artículos. Despues de una breve introdueción a su biografía académica, se analiza y explica el papel esencial que Víctor Sánchez de Zavala tuvo en la introducción de la gramatíca generativa en España. Se examina en este sentido su trabajo corno profesor, editor, traductor y escritor y la Iínea central de su trabajo lingüístico. La segunda parte del artículo analiza las hipótesis fundamentales de la teoda pragmática desarrollada por este filósofo y lingüísta a lo largo de toda su vida. En esta sección, por otra parte, se presenta y discute su novedoso enfoque global de la actividad lingüística expuesta en su obra póstuma, de reciente aparieión: Hacia la pragmática (psicoIógica), Madrid, Visor.This paper reviews Víctor Sánehez de Zavala’s main contributions to linguistics and philosophy through a close look at the central ideas developed in his articles and books. In the first part, after a brief introduction to his academic biography, the leading role of Víctor Sánchez de Zavada in the introduction of formal linguistics in Spain is analysed and justified. His work as editor, professor, translator and writer is examined through his main publications. The second part of the paper is devoted to provide an analysis of the central hypotheses on which this theory of psychologicaI pragmatics is based. Furthermore, this second part examines his novel and global approach to linguistic activity, developed in his posthumous book Towards a psychological pragmatics.

En este trabajo sc presenta un marco general en el que desarrollar una “ontoepistemo-semántica” para las teodas científicas y sus terminos característicos. En primer lugar, se defiende la esencialidad de los aspectos ontologicos y epistemológicos para la semantica y se hacen explícitos los principios generales que constituyen dicho marco. A continuación, se aplican estos principios al análisis ontoepistemosemántico de cada uno de los tres tipos principales de términos científicos: términos relacionales y funcionales con contenido empírico, términos matemáticos puros y términos para los dominios ontológicos básicos.In this paper I offer a general framework for all “ontoepistenlosemantics” of scientific theories and scientific terms. First, I argue for the essential dependence of semantics on ontological and epistemological aspects and I make explicit the general principIes that make up this frame. Then, I apply these principles to the ontoepistemosmantical analysis of the three main kinds of scientific terms: relational and functional term with empirical content, purely mathematical terms and terms for basic ontological domains.

“Prediction” and “prescription” are crucial notions for economics. This paper offers a philosophical and methodological approach and takes into account the connection with the problem of science and values. To do this, two steps are followed: firstly, prediction in economics -its characteristics and limits- will be examined and, secondly, the role of prescription in economics (and its relations with internal and external values) will be studied. Thus; the underlying aims of this paper are to make explicit the characters of economic prediction, to show its nexus with the economic prescription and to point out the links of both -especially, the latter- with the specific values of “economic activity” and the values of “economics as activity” (i. e., values of economic undertaking as an activity interconnected with others in the social context).

Trois sortes de définitions sont présentées et discutées: les définitions nominales, les définitions contextuelles et les définitions amplificatrices. On insiste sur le fait que I’elimination des definitions n’est pas forcement un procede automatique en particulier dans le cas de la logique paraconsistante. Finalement on s’int’resse à la théorie des objets de Meinong et l’on montre comment elle peut êrre considéréecomme une théorie des descripteurs.Three kinds of definitions are presented and discussed: nominal definitions, contextual definitions, amplifying definitions. It is emphasized that the elimination of definitions is not necessarily straightforward in particular in the case of paraconsistent logic. Finally we have a look at Meinong’s theory objects and we show how it can be considered as a theory of descriptors.

This essay is concerned with the special difficulties that arise in testing and appraising mainstream economic theory. I argue that, like other theories designed to apply to complex open systems, it is very hard to confirm mainsteam economics. Parts can be tested and appraised, but the theory is only very weakly supported by evidence.

Defiendo la legitimidad de la pregunta acerca de cuál puede ser el estatuto cognitivo de la Teoría Económica, y sostengo que la Teoría se comprende mejor como una rama de la Filosofía Política formal, en concreto, como una especie de contractualismo. Esto parece particularmente adecuado corno explicación de la Teoría deI equilibrio general. Dado el carácter intencional de las variables explicativas de la Teoría Económica y el papel de la información al realizar una elección, se argumenta que es improbable que dicha Teoría pueda garantizar el poder predictivo, que le permitiría funcionar corno teoría factual en vez de corno teoría normativa.I defend the integrity of the question of what the cognitive status of economic theory could amount to, and I argue that the theory is best understood as a compartment of formal political philosophy, in particular a species of contractarianism. This seems particularly apt as an account of general equilibrium theory. Given the intentional character of the explanatory variables of economic theory and the role of information in effecting choice, it is argued that economic theory is unlikely to secure the predictive power that would enable it to function as a factual instead of a normative theory.

A través de los recursos esenciales de la semantica de los mundos posibles se comparan y relacionan, por un lado, la dimensión científica y filosófica, y por otro, la dimensión tecnica y la utópica, utilizándose para ello las relaciones entre composibilidad (o compatibilidad) y existencia, y entre el mundo actual, en el que opera la técnica, y mundos posibles, hacia los que se proyecta la utopía. En esta tarea resulta de interés prestar atención a la problematica clasica acerca de los poliedros posibles e imposibles, en relación con el problema de la afectación, exclusión o ajuste de los “monstruos” de la lógica o de la razón.Through the essential means of the semantics of possible worlds, some dimensions are compared and related: firstly, the scientific and philosophical dimension, and secondly the technical and utopian dimension. For that purpose the relationship between compossibility (or compatibility) and existence are used as well as that between the real world, in which technique works, and possible worlds, towards utopia is oriented. In this task it is interesting to pay attention to the classic issue of possible and impossible polyhedrons, concerning affectation, exclusion or fitting of “monsters” of logic or of reason.

As science deals with invariants and history with dated events, the phrase “historical science” might be thought to be an oxymoron. However, the prevalence in the natural sciences and economics of differential equations filled with time derivatives should persuade us of the legitimacy of joining history with science. The combination can, in fact, take several forms. This paper examines some of the ways inwhich history and economics can be fashioned into economic history, and the reasons why they need to be so joined.A particularly important source of historicity in economics is that boundedly rational economic actors represent the economic scene in radically different ways from time to time, and these changes occur as a function of natural and social events, social influences on perception, and the molding of human motives by the social environment, which is itself time dependent. For these and other reasons, many of thembound closely to basic human characteristics, the dynamic movements of the economic system depend not only on invariant laws, but on continually changing boundary conditions as weIl.

A few aspects of the issue of realism are addressed in the context of a social science. The paper looks for adjustments needed in our conceptions of scientiflc realism to accommodate some peculiarities of economics. Ontologically speaking, economics appears to be closely linked to commonsense conceptions of the world, thus the problem of theoretical concepts does not emerge in the same form it is often taken to exist in physics. Theory formation is largely a matter of idealization and isolation among observables rather than postulation of unobservables. Given that isolative theories violate the truth in many ways, truth is more of a problem than existence in a realism pertaining to economics. The idea of significant truth -which is able to tolerare varieties of untruths in theories- is suggested to be based on the notion of the way the world works; this is a matter of the causal structure and functioning of the world. None of this is undermined by the acknowledgement that economist’s attittudes and decisions are shapped by rhetorical persuasion.
