Carlos Minguez Sobre el valor de las matemáticas: Juan Luis Vives y el Prefacio de Osiander
abstract | view |  rights & permissions
This paper analyses some aspects in Osiander’s (1498-1552) “Preface” to De Revolutionibus (1543) by Nicolaus Copernicus (1473-1453) and the “Preface Letter” also by Copernicus to the Pope Paul III (1468-1549). The reading is carried out from the intellectual framework where the works are written, taking as a reference De Disciplinis (1531) by Juan Luis Vives (1492-1538), whose pedagogical thought had great influence on the 16th century. This paper points at the coincidence of attitudes as to the function of Mathematics, and therefore, of Astronomy, for both a purely probabilistic assessment of theastronomical hypotheses, and the overcoming of the instrumentality of the calculations by means of their practical use. This last channel, promoted by a sceptic academicism which was already present in the first half of the 16th century, contributes to a better understanding of the reality of the progressive acceptation of a new structure of the world. Vives has very frequently been talked of as the clear antecedent of the great masters of thought of the modern culture, but his style and the dynamics of his thought -totally Humanist- are very different from those of Copernicus and Osiander, and thus, this paper aims to analyse his cultural context and his reflections about himself.

Dov M. Gabbay A General Theory of Structured Consequence Relations
abstract | view |  rights & permissions
There are several areas in logic where the monotonicity of the consequence relation fails to hold. Roughly these are the traditional non-monotonic systems arising in Artificial Intelligence (such as defeasible logics, circumscription, defaults, ete), numerical non-monotonic systems (probabilistic systems, fuzzy logics, belief functions), resource logics (also called substructural logics such as relevance logic, linear logic, Lambek calculus), and the logic of theory change (also called belief revision, see Alchourron, Gärdenfors, Makinson [2224]). We are seeking a common axiomatic and semantical approach to the notion of consequence whieh can be specialised to any of the above areas. This paper introduces the notions of structured consequence relation, shift operators and structural connectives, and shows an intrinsic connection between the above areas.

John Corcoran Information Recovery Problems
abstract | view |  rights & permissions
An information recovery problem is the problem of constructing a proposition containing the information dropped in going from a given premise to a given conclusion that folIows. The proposition(s) to beconstructed can be required to satisfy other conditions as well, e.g. being independent of the conclusion, or being “informationally unconnected” with the conclusion, or some other condition dictated by the context. This paper discusses various types of such problems, it presents techniques and principles useful in solving them, and it develops algorithmic methods for certain classes of such problems. The results are then applied to classical number theory, in particular, to questions concerning possible refinements of the 1931 Gödel Axiom Set, e.g. whether any of its axioms can be analyzed into “informational atoms”. Two propositions are “informationally unconnected” [with each other] if no informative (nontautological) consequence of one also follows from the other. A proposition is an “informational atom” if it is informative but no information can be dropped from it without rendering it uninformative (tautological). Presentation, employment, and investigation of these two new concepts are prominent features of this paper.

Víctor Sanchez de Zavala Towards a less simple but sounder (psychologieal) Pragmatics III
abstract | view |  rights & permissions
Before processual analyses of the activities of Iinguistic emission and reception are performed, a modicum of elaboration of the notions and technical devices previously suggested is necessary. First, theoretical resources previously developed are revised in two different fashions: some require to be elaborated in higher detail, while in other cases what is needed is to remove, at least in part, some restrictions initially laid down for simplification purposes. Then some notional clarifications and new specific distinctions a.nd notions are suggested for the study of emission, since the fact that this kind of linguistic performance is all but ignored in traditional (psychological) Pragmatics calls for an attempt to dispel some confusions originating in such a virtual neglect, and, on the other hand, for creation of a suitable array of such theoretical tools.
