John Corcoran Information Recovery Problems
abstract | view |  rights & permissions | cited by
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.

Luis Vega Demostraciones clásicas
abstract | view |  rights & permissions | cited by
Let’s agree in calling “classical demonstration” a deduction that enables us to know the rational necessity that something is the case and cannot be otherwise. I propose to take seriously actual instances of this notion, e.g. some mathematical proofs, and explore certain discoursive and epistemic implications of their existence. Then I will look at questions about characterizing, rigorizing and acknowledging this kind of conclusive proof. Finally, some remarks on the meaning of Provability Logic in this context will be made.

Víctor Sanchez de Zavala Towards a less simple but sounder (psychologieal) Pragmatics III
abstract | view |  rights & permissions | cited by
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.
