He attended university at Jena and Berlin. His first response to Quine came in “Meaning postulates” where Carnap suggested that analytic statements are those which can be derived from a set of appropriate sentences that he called meaning postulates. O n and theoretical terms T He also solved the problem of the meaning of the statement x N[A x ], where A x is a sentence in which the individual variable x occurs.

His main concerns were i to give an account of the distinction between analytic and synthetic statements and ii to give a suitable formulation of the verifiability principle; that is, to find a criterion of significance appropriate to scientific language.

The meaning of a concept thus depends on the theory in which that concept is used. In Meaning and Necessity.

Let T be the conjunction of all purely theoretical axioms, and C the conjunction of all correspondence postulates and TC the conjunction of T and C.


Thus it is necessary to build an inductive logic; that is, a logic which studies the logical relations between statements and evidence. Qa is not a logical consequence of the premises; therefore this kind of explanation determines only a certain degree of confirmation for the event we want to explain. Quine from the U. At the same time, Carnap met Alfred Tarski, who jeaning developing his semantical theory of truth.

In some ways the distinction between observational and theoretical terms is similar to that between macro-events, which are characterized by physical quantities that remain constant over a large portion of space and time, ane micro-events, where physical quantities change rapidly in space or time. InCarnap moved to Prague to become professor of natural philosophy at the German University.

The Changing Face of Experimentation. Markus Schrenk – – In U. The sets of meaning postulates and rules of correspondence may be included testabiilty the set of non-logical axioms. Wojcicki and Przelecki’s research is independent of the distinction between observational and theoretical terms, i.

He asserted that many philosophical problems are indeed pseudo-problems, the outcome of a misuse of language. Np means “p is logically true”, and the last statement belongs to the meta-language; thus N is not explicitly definable in the language of a formal logic, and we cannot eliminate the term N.

Reiner Hedrich – unknown. Intuitive space, with its synthetic a priori character, is a concession to Kantian philosophy. The Philosophy of Rudolf Carnap contains the most complete bibliography of Carnap’s work. One of the main purposes of the philosophy of science is to show the difference between the various kinds of statements. In Carnap’s opinion, a scientific theory is an interpreted axiomatic formal system.

A is called “extensional with respect to p” if and only if the truth value of A does not change if we substitute the sentence p with an equivalent sentence q. Carnap Rudolf Carnap May 18, — September 14, was a key figure of the Vienna Circle and the most important of the logical empiricists.
