Tras estudiar teología, filosofía y matemáticas, fue ordenado sacerdote en 1805. Profesor de religión en Praga y matemático aficionado, en 1820 las autoridades le prohibieron ejercer cualquier actividad académica a causa de su posicionamiento crítico con respecto a las condiciones sociales vigentes en el Imperio Austrohúngaro. Las inquietudes científicas de Bolzano resultaron muy avanzadas para su tiempo, preocupado como estaba por los fundamentos de varias ramas de la matemática, a saber, la teoría de las funciones, la lógica y la noción de cardinal. Tras demostrar el teorema del valors intermedio, dio el primer ejemplo de una función continua no derivable sobre el conjunto de los números reales. En el campo de la lógica, trató la tabla de verdad de una proposición e introdujo la primera definición operativa de deducibilidad. Así mismo estudió, con anterioridad a Cantor, los conjuntos infinitos. Inicio Buscador Recomendar sitio

BERNHARD BOLZANO A cura di Alessandro Sangalli Il contributo filosofico di Bernhard Bolzano, pensatore e matematico boemo, fu pienamente riconosciuto solo molto tempo dopo la sua morte. Il suo lavoro si rivelò particolarmente utile nel campo della logica, della geometria e per la teoria dei numeri reali. Bernardus Placidus Johann Nepomuk Bolzano nacque a Praga, in Boemia (oggi parte della Repubblica Ceca), il 5 ottobre 1781. Il padre era un commerciante d’arte e, come la madre, un fervido cristiano. Bernard crebbe così con solidi valori morali e princìpi su cui fare sicuro affidamento: fu questa sua educazione a spingerlo verso la Chiesa e la vita sacerdotale. Bolzano entrò all’Università di Praga nel 1796 e lì studiò filosofia, matematica e fisica. Dopo la laurea, entrò a far parte del Dipartimento di Teologia dell’istituto e fu ordinato prete cattolico nel 1804. Nonostante la sua piena dedizione alla vita ecclesiastica, egli non trascurò mai i suoi interessi negli studi matematici, tanto che fu segnalato per il ruolo di presidente del Dipartimento di Matematica universitario. Il 1805 vide l’inizio della lotta che avrebbe caratterizzato tutta la vita di Bolzano. L’impero austro-ungarico comprendeva a quel tempo diversi gruppi etnici che non nascondevano desideri nazionalistici e movimenti per d’indipendenza: incoraggiati dal “libero pensiero” della recente Rivoluzione francese, questi movimenti stavano diventando un serio problema per l’unità dell’impero. Perciò, con una mossa politica, l’impero creò una cattedra di Filosofia della Religione in ogni università dello stato: questa mossa era parte di un più ampio progetto di sostegno della Chiesa cattolica, il cui conservatorismo avrebbe aiutato le autorità imperiali a tenere sotto controllo i liberi pensatori.

B. 1805-tõl 1819-ig vallástudományt és hitvédelmet tanított a prágai egyetemen, ám ebbõl az állásából a felvilágosodás eszméi és a dogmatika kérdéseinek racionális kritikája miatt felmentették és átmenetileg a publikálástól is eltiltották. Ettõl kezdve lényegében magántudósként élt vidéki barátainál illetve Prágában és ekkor adta közre legfontosabb matematikai és vallásbölcseleti munkáit. Matematikai szakmunkáinak köszönhetõen B. a modern matematikai analízis és a halmazelmélet egyik klasszikusa, a Bolzano-Weierstrass-tétel megfogalmazója. Legalább ennyire jelentõs logikai életmûve: Tudománytan címû, Leibniz platonizáló idealizmusára építõ munkájában a logikai állítások alapját jelentõ magánvaló igazságok objektivitását élesen megkülönböztette a logikai igazságok pusztán gondolati, az emberi megismerésben konstituálódó természetétõl, azaz a valóság valódi logikáját a logikai érvényesség gondolati világától.

Username: Password: Sites for teachers Sites for parents Awards Interactive Activities ... Sites for parents Intuition and Rigor One of the torch bearers of the formalization attempts in the 19th century was the Czech analyst Bernhard Bolzano (1781-1848.) In his critique of the attempts to prove the Fundamental Theorem of Algebra, he wrote The most common kind of proof depends on a truth borrowed from geometry, namely, that every continuous line of simple curvature of which the ordinates are first positive and then negative (or conversely) must necessarily intersect the x-axis somewhere at a point that lies in between those ordinates. There is certainly no question concerning the correctness, nor indeed the obviousness, of this geometrical proposition. But it is clear that it is an intolerable offense against correct method to derive truths of pure (or general) mathematics (i.e., arithmetic, algebra, analysis) from considerations which belong to a merely applied (or special) part, namely, geometry ... By which he of course meant that reliance on the geometrical intuition is an unacceptable tool in deriving analytic truths. He clearly accepts the statement as true but objects to the fact of its being used offhandedly, as a self-evident truth. In the article, Bolzano proceeds to justify the statement that is variably now known as Bolzano's or the Intermediate Value Theorem.
