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.

José Ferrater Mora Nota sobre “Los lenguajes de la historia”
abstract | view |  rights & permissions
The article starts from previous contributions by the author about “Languages of History” (Dianoia, 1970), in which he distinguished three types of statements used by historians. In this context, he analyzes the various relationships between these three following languages (I, 11 and III): the positivist, the hermeneutic, and the recursive ones. After analyzing the two first ways in their strong and weak versions, the author decides in favour of the third one, in its weak or informal version.

Miguel Ángel Quintanilla EI concepto de verdad parcial
abstract | view |  rights & permissions
There are two kinds of philosophical problems in the theory of partial truth: semantical and methodological problems. The semantics of partial truth must be clarified by some standard system of multivaluedlogic. Fuzzy set theory should be applied to solve some methodological problems.

abstract | view |  rights & permissions
EI gran filósofo catalón, español, iberoamericano y universal Juan David García Bacca, cuya obra inmensa y de impresionante variedad y proyección sobre todas las áreas cientfíicas y humanas se sigue acrecentando cada día, a sus 84 años de edad, con nuevas creaciones -hombre a quien THEORIA tanto debe como inspirador, colaborador y fiel apoyo, desde su exilio venezolano, en los tiempos dificiles de la primera salida de la revista, entre 1952 y 1956- ha querido hoy hacernos llegar, junto a su primer artículo para la nueva etapa, que publicamos en las páginas siguientes, su cordial saludo a la nueva THEORIA, que reproducimos a continuación.

Héctor-Neri Castañeda Negaciones, imperativos, colores, existencia y la paradoja de Bertrand Russell
abstract | view |  rights & permissions
This is a multifaceted semantico-ontological investigation of different types of families of concepts and properties. One major result is that contrast between: (a) the ontologically egalitarian or democratic, but epistemologically hierarchical family of colors, and (b) the ontologically hierarchical or pyramidal familiy of negations. The different negations (of propositions, imperatives, properties, predication) are studied, and the unity of the whole family under a genus reveals the pyramidal structure of the family. The negation or properties has a powerful bearing on Russell’s paradox -- which shows different strands in negation. The connections between existence and negation provides an introduction to Guise Theory and reveals some limitations in Bertrand Russell’s analysis of definite descriptions.
