En este trabajo nos proponemos acercarnos a la noción del conocimiento simbólico en la obra de Gottfried Leibniz, rastreándola en diversos textos de su autoría en que se encuentra diseminada. Comenzamos con la importante distinción entre idea y concepto, que separa el planteo de nuestro autor de las formulaciones de otros como Descartes, Malebranche y Spinoza. Seguimos con la clasificación de los tipos de conceptos que el filósofo de Leipzig lleva acabo, en la que divide a los conceptos simbólicos de (...) los intuitivos. Abordamos después las ventajas epistemológicas que presenta el pensamiento simbólico frente al pensamiento verbal, analizando sus funciones cognitivas y su rol en diferentes tipos de sistemas semióticos. Continuamos asentando el simbolismo epistemológico dentro de una teoría general de la representación, que sostiene cierto isomorfismo entre las esferas del lenguaje, el pensamiento y la realidad. Finalmente, fundamentamos ontológicamente esta analogía representativa estructural en la noción leibniziana de expresión y la vinculamos con el perspectivismo monadológico, poniendo de relieve su cercanía con algunos planteos fenomenológicos y hermenéuticos de nuestros días.

We present sequent calculi for normal modal logics where modal and propositional behaviours are separated, and we prove a cut elimination theorem for the basic system K, so as completeness theorems both for K itself and for its most popular enrichments. MSC: 03B45, 03F05.

We develop cut-free calculi of sequents for normal modal logics by using treesequents, which are trees of sequences of formulas. We introduce modal operators corresponding to the ways we move formulas along the branches of such trees, only considering fixed distance movements. Finally, we exhibit syntactic cut-elimination theorems for all the main normal modal logics.

The Italian translation of writings by W. von Humboldt recently edited by G. Moretto and F. Tessitore makes it possible to obtain a picture of Humboldt’s philosophy more complete than those which have been for a long time dominating. The results of Tessitore’s researches, which are summarized in his Introduction, underline the most fundamental aspects of Humboldt’s thought, i.e. the pivotal role played in it, as in Schiller’s, by an anthropology based on the ideas of force, energy and individuality; and (...) a vision of history, hostile to the apriorism and the teleological bent of the philosophy of history originating in Kant and carried on by Schelling, Fichte, Hegel, and centering on the notion of an individuality irreducible to any abstract and deterministic scheme, which inaugurates that historicistic conception of philosophy and life which has to be regarded as the other great current of thought born in the Goethezeit, alternative to the idealist one.

The series is devoted to the study of scientific and philosophical texts from the Classical and the Islamic world handed down in Arabic. Through critical text editions and monographs, it provides access to ancient scientific inquiry as it developed in a continuous tradition from Antiquity to the modern period. All editions are accompanied by translations and philological and explanatory notes.
