Ernesto García Camarero Bases de datos y representación del conocimiento
abstract | view |  rights & permissions
The computer has three fundamental analogies with the human being (senses, memory and intelligence), but the coming out of the data bases announced a new form of language: the computer language. The data bases not only set several new technical and social problems, but moreover are modifying the traditional form of social memory, supported by paper, by changing it in a memory based on electronic means. This situation creates new forms of representation of knowledge to which the author gave attention in previous contributions with his SENECA project, in which computer language tries to give a synthesis of oral and written languages, with their respective advantages.

José Hierro Pescador Mundos imposibles
abstract | view |  rights & permissions
An impossible world is a world which necessarily does not exist. Besides the paradigm of necessity, wich is logical necesslty, we must consider physical necessity and ethical necessity, both of wich can beexpressed in terms of logical necessity, in the way suggested by Montague. Accordingly, an impossible world can be logically impossible, physically impossible or ethically impossible, but in every case the impossibility can be reduced to logical impossibility, and in consequence an impossible world is irrational and cannot be understood by us. An illustration is taken from the incongruities of Kafka’s story in Di Verwandlung.

Lorenzo Peña Agregados, sistemas y euerpos: un enfoque difuso-conjuntual
abstract | view |  rights & permissions
A Fuzzy-Set Theoretical Framework -resting on a paraconsistent infinite-valued logic- is sketched, wherein a thorough ontological-reduction program can be carried out. The framework includes formulae of the form “x comprises z in the time-interval e”. Reducing aggregates to sets thus handled is shown to escape usual objections. Likewise, systems generally can be regarded as aggregates, hence as (fuzzy) sets -the purported nonextensionality of systems objection being disposed of owing to our system’s recognizing infinitely many membership degrees. So do bodies, too, which enables us to find a solutionto Unger’s sorites concerning ordinary material bodies.

Mario Bunge ¿Qué es un individuo concreto?
abstract | view |  rights & permissions
The paper investigates the problems whether a concrete individual can be defined as a set or be characterized by an abstract theory. In particular, Jesês Mosterín’s objection to a theory of things proposed by the present author is discussed. Also, the view of scientific theories held by Sneed, and adopted by Mosterln, is analyzed. It is concluded that any adequate description of a concrete individual calls for more than a mathematical formalism.

Javier de Lorenzo Pascal y los indivisibles
abstract | view |  rights & permissions
The pascalian use of indivisibles is here considered in the context of the theological and mathematical debates of the time, by distinguishing it clearly from this of Cavalieri. The combinatory and geometrical approaches are closely linked in Pascal’s work. His use of indivisibles has a heuristic, inventive character and not only a demonstrative one. Ontologically speaking, it stems out from the acceptance of actual infinite. The use of the symmetry axiom of Archimedes is the basis of the pascalian use of the infinitesimals, which has, in other respects, some close connexions with the Leibnizian conception of infinitesimals.

Eloy Rada Teorías y significado
abstract | view |  rights & permissions
The purpose of this paper is to outline a thesis which in some ways attemts to retrieve the value of meaning as a constituent element of theories. It will be argued that theories possess in common a more or less explicit relational structure, but, at the same time, they possess a meaningful function by means of which they are instruments of knowledge or, rather, by means of which theories have the value ofknowledge in science. In conclusion, it will be suggested that this approach to theories allows those with weak relational structure (social, historical theories, etc.) to be treated with a degree of adequacy by the philosophy of science. Likewise, it will be suggested that the method of semantic analysis linked to the theory of “possible worlds” could be fruitful for this purpose.
