The question of finding a suitable formal account of meaning for the logical signs has troubled many philosophers and logicians since the early days of formal logic, whenever it is even recognised as a problem. Here I attempt to show how two operational approaches to the problem can still be shown to be ‘technically’ equivalent, despite having emerged from two different readings of a single philosophical account, and being essentially distinct with respect to the rôle of ‘will’ in the mathematical (...) activity: on the one hand, the ‘semantics of use’, my own reformulation of P. Martin‐Löf's Intuitionistic Type Theory canonical‐values based semantics by taking the normalisation rules as the key semantical device; and, on the other hand, J. Hintikka's Game‐Theoretical Semantics, where the meaning of logical signs is given via semantical games. The philosophical account from which both emerge is precisely Wittgenstein's later account of propositions, where the notion of ‘language‐games’ is introduced as a key semantical device. Observing that the normalisation rules seem to be able to formalise the explanation of the consequences one can draw from a proposition,3 thus showing the function/purpose/usefulness of its main connective in the calculus of language, it seems reasonable to advocate that such a meta‐mathematical device can be a semantically useful notion which would lead to a more reasonable account of the problem of formulating the meaning of logical constants.

Utilizando el argumento de la novela Bouvard y Pécuchetde Flaubert, como posible refutación del Mundo 3 de Popper, analizamos algunas de las principales consecuencias que para la filosofía de la mente, así como para la ciencia y el conocimiento, tiene el pensamiento popperiano sobre el llamado mundo del conocimiento objetivo.

The purpose of this paper is studying the importance of the antithetical pair sympathy-antipathy, as an interpretive instrument of the human phýsis in the Hippocratic medical epistemology. His study aims to be a contribution to the understanding of the methods of inference developed by ancient medicine, in parallel to the demonstrative method.

Este artículo pretende establecer la importancia del Proyecto de una psicología para neurólogos en el conjunto de la obra de Freud, señalando aquellos puntos en los que anticipa la teoría que, unos años más tarde, revolucionará el pensamiento humano, es decir, aquella que define el campo del psicoanálisis y que tiene a los conceptos de aparato psíquico y de inconsciente como ejes centrales.
