The first one is logical and deals with the degree to which a given hypothesis is confirmed by a piece of evidence. He wrote a letter to Russell, who responded by copying by hand long passages from his Principia Mathematica for Carnap's benefit, as neither Carnap nor his university could afford a copy of this epochal work. © 2019 Encyclopedia.com | All rights reserved. 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. He believed that one had to isolate the experiential elements from the logical elements of a given body of knowledge. But, such a statement can always receive a certain logical value, given the fact that this value only depends on the meaning of its symbols. [22] Carnap was raised in a profoundly Protestant religious family, but later became an atheist.[23][24]. For Carnap thought that in many instances those disciplines use the same concepts, but with totally different meanings. That implies that formal languages are constructed and that everyone is free to choose the language it finds more suited to his purpose.

Convinced in the early 1930s by his research and by discussions with his colleagues of the Vienna Circle (of which he was a leading member) of the untenability of his original position, Carnap rejected phenomenalism for physicalism, reinterpreting the empirical basis of protocol statements concerning physical observations and measurements and rejoining translatability—being able to eliminate theoretical terms—in favor of testability— being able to test derived observations—as the criterion of meaning. This work, successful technically, failed to have the philosophical impact he anticipated because of his inability to establish convincingly a unique probability concept. In that hierarchy, all concepts are organized according to a fundamental arrangement where concepts can be reduced and converted to other basic ones. In this dissertation on the philosophical foundations of geometry, Carnap tried to provide a logical basis for a theory of space and time in physics.
