[22] Carnap was raised in a profoundly Protestant religious family, but later became an atheist.[23][24]. « Meaning and Synonymy in Natural Languages ». "Carnap had a modest but deeply religious family background, which might explain why, although he later became an atheist, he maintained a respectful and tolerant attitude in matters of faith throughout his life." À partir de 1941, il s'engage dans un vaste projet de logique inductive et de fondement logique des probabilités, auquel il travaillera jusqu'à la fin de sa vie. « Die Mathematik als Zweig der Logik ». 4,6 sur 5 étoiles 3. [30] Much of the content has been digitized. modifier - modifier le code - modifier Wikidata. « Von Gott und Seele. « Truth in Mathematics and Logic ». He married his second wife, Elizabeth Ina Stöger, in 1933. ». On these occasions he learned much about Tarski's model theoretic method of semantics. 1971. The second is empirical, and relates to the long run rate of one observable feature of nature relative to another. « Logic », in E. D. Adrian et al., éd.. 1937. They do not refer to states of affairs and the things they denote cannot be perceived. 1931. Commença alors avec Quine, qui dans les deux dogmes de l'empirisme critique le positivisme logique, un débat riche et divers sur leurs positions épistémologiques respectives, dont un des points d'achoppement reste l'acceptation d'une division des énoncés scientifiques entre énoncés analytiques a priori et énoncés synthétiques a posteriori [réf. Une des idées de Carnap est alors que les problèmes métaphysiques ou philosophiques sont des erreurs syntaxiques à dissoudre, des énoncés ou des questions dénués de sens. the traditional philosophy that finds its roots in mythical and religious thought. 1946. ), 2005, *This volume concludes with Carnap's "Replies and Systematic Expositions" (pp. « Remarks on Induction and Truth ». Buldt, Bernd: "Carnap, Paul Rudolf". « Theory and Prediction in Science ». To verify a sentence, one needs to expound the empirical conditions and circumstances that would establish the truth of the sentence. In fact, Carnap claims that the problem of induction is a matter of finding a precise explanation of the logical relation that holds between a hypothesis and the evidence that supports it. Part II », in Richard Jeffrey, éd.. 1993. According to Carnap, those agreements are possible only through the detailed presentation of the meaning and use of the expressions of a language. Rudolf Carnap (Ronsdorf, 18 Mei 1891 – Santa Monica (Kalifornië), 14 September 1970) was 'n Duitse filosoof en een van die belangrikste verteenwoordigers van die logiese positivisme. He accepted the effort to surpass traditional philosophy with logical innovations that inform the sciences. Carnap sees language as a calculus. (avec Hans Hahn et Otto Neurath - publié anonymement) « Wissenschaftliche Weltauffassung: Der Wiener Kreis », Vienne, Artur Wolf. Paul Rudolf Carnap's Geni Profile. The main objective of Carnap's dissertation was to show that the inconsistencies between theories concerning space only existed because philosophers, as well as mathematicians and scientists, were talking about different things while using the same “space” word. On the contrary, statements belonging to the first concept do not say anything about facts. Cédric Paternotte, « Logique inductive et décisions rationnelles », in Rudolf Carnap. « Die logizistische Grundlegung der Mathematik ». Malisoff. Considering that Carnap was interested in pure mathematics, natural sciences and philosophy, his dissertation can be seen as an attempt to build a bridge between the different disciplines that are geometry, physics and philosophy.
