Javier Echeverría La identidad de las figuras geométricas
abstract | view |  rights & permissions
The Erlanger Program of F. Klein ensures a ground for the ὲ́κθεσις procedure, which has not been much studied in the recent debates about geometrical analysis, but refers to a more general problem: the identity of a sign within a sign system, and the attempts of reduction of the mentioned system by another one. The exampIe considered is the reduction of the conics to characteristic rectangles realized by Apollonius. Starting from Klein and Apollonius, as weIl as from cartesian geometry, the figures are considered as geometric signs, and the proposed analysis of sign identity are conceived as models to follow in the analysis of identity of mathematical signs in general.

Yon Pérez Laraudogoitia Interpretación modal de la mecánica cuántica
abstract | view |  rights & permissions
In this paper, we present a (propositionaI) modal-Iogic approximation to Quantum Mechanics from a reduced and characteristic number of “crucial experiments” and so independently of the lattice of subspaces of Hilbert space. Kripke’s semantics, which determinates this system, allows to define, from a new point of view, the notions of “measurement process” and “virtual world” and admits a natural interpretation which in turn can help us to understand the measurement problem. In this way, we can attempt a “many-worlds” interpretation of Quantum Mechanics, in the way of Everett.

Yosu Yurramendi Analisis de datos y lógica de enunciados
abstract | view |  rights & permissions
We understand by data analysis the full set of methods which are used to point out the structural relations between certain objects and the characteristics observed in them. In the case where these characteristics admit a process of dichotomy, the relations can be expressed in terms of propositional logic.In the present paper, we endeavour to make clear the opposition between the problems of propositional logic and those of certain model utilised in data analysis: in propositional logic, we look for a solution verified by a given set of propositions; as long as we are concerned with data analysis, we look for a solution in terms of propositions which include as proper parts the observed objects.Finally, we draw the main lines of two very used methods which can be relevant with the aid of computer: the factor analysis and the automatic classification (cluster analysis).

Dora Sanchez Garcia Definición de la norma verdadera
abstract | view |  rights & permissions
In this article, we will concentrate on the two true norm definitions that have existed throughout the history of the Deontic Logic: that offered by Professor Kalinowski and that proposed by the semantics of possible worlds. The former is based on Tarski’s definition of the true proposition, but it has the drawback of depending on a concrete, philosophical theory concerning the nature of norms. The latter, widely accepted nowadays, presents difficulties which we will analyse, using as a reference, K. Solt’s critique. Despite its limitations, it offers the indisputable advantage of being independant of any concrete, philosophical option, and indicates, in our opinion, the correct way of proceeding.

Constancio de Castro Aguirre Las Ciencias Comportamentales, nueva frontera deI saber positivo
abstract | view |  rights & permissions
There is a credibility decay on positive knowledge among the social scientists and particularly among the psychologists. Certainly different prejudices dwell upon this phenomenon. First and principal the usually made identity of positive and natural knowledge. This belief is also fed by many others such as that one which assumes that every quantification, which is a consequence of positive knowledge,follows the model of the Physical Sciences. We consider that all these prejudices do not keep in mind the work done in the last decades on the Theories of Measure. We consider also that psychophysical methods which have been introduced by Stevens present a stimulating program for the behavioral sciences and they open a new frontiere to the positive knowledge.

Mario Bunge ¿Grados de existencia o de abstracción?
abstract | view |  rights & permissions
A simplification of the notion of degree of existence, introduced by María Manzano, is proposed. And it is suggested that actually it exactifies a notion of degree of abstraction, not of existence.

This paper offers an account of observation from a realist view. Observation is considered here as a process of information gathering from the environment; the performance of which will be more or less succesfull depending on the theories underlying this process.
