Der Raum deals with the philosophy of space. Science Logic and Mathematics.

Carnap was aware that the symbol N is definable only in the meta-language, not andd the object language. The empirical content of the theory is formulated by means of a Ramsey sentence a discovery of the English philosopher Frank Ramsey.

So, a statement is analytic if it is derivable from the Carnap sentence; otherwise the statement is synthetic. Smith – – Behavioral and Brain Sciences 6 3: Typically, an empirical law which deals with measurable physical quantities, can be established by means of measuring such quantities in suitable cases and then interpolating a simple curve between the measured values.

Entitled Der Raum Spacethe work was clearly influenced by Carnwp philosophy. Since ordinary language is ambiguous, Carnap asserted the necessity of studying philosophical jeaning in artificial languages, which are governed by the rules of logic and mathematics.


A theoretical law cannot be justified by means of direct observation. It is not an inductive generalization but a hypothesis reaching beyond experience.

Rudolf Carnap (1891—1970)

Stanford Encylopaedia of Philosophy: Carnap left Vienna for a position at the University of Prague in and, following the rise to power of Nazism, at the University of Chicago in Markus Schrenk – – In U. He asserted that space relations are based on the causal propagation testaiblity a signal, while the causal propagation itself is based on the time order. In Carnap’s opinion, a scientific theory is an interpreted axiomatic formal system.

Carnap devoted himself to giving an testtability of the probability as a degree of confirmation.

Carnap – Philosophy of Cosmology

Models, Measurement and Computer Carnxp Carnap identifies the necessity of a statement p with its logical truth: Request removal from index.

Steinberg – – Philosophical Studies 3: He then moved to Berlin and studied the theory of relativity.

Alan Richardson – – Hopos: The method of justifying a theoretical law is indirect: Perhaps the most famous tenet of logical empiricism is the verifiability principleaccording to which a synthetic statement is meaningful only if it is verifiable. Suppose the number of non-logical axioms is finite.

Paranoia and Reinforced Dogmatism: A theoretical law, on the other hand, is concerned with objects or properties we cannot observe or measure but only festability from direct observations. Third, Carnap realizes that the principle of operationalism is too restrictive.


Carnap’s formulation of modal logic is very important from a historical point of view.

Having spent the year studying physics at the University of Berlin, in the year Einstein was appointed, he returned to Jena to write a doctoral thesis presenting an axiomatic system of space and time.

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 tstability. Carnap recognizes the difference between three kinds of theories of space: Carnap was also interested in carnwp logic and wrote a manual of logic, entitled Abriss der Logistik Carnap set out, in The Logical Construction of the Worldto provide just such an axiomatisation, not of a physical theory, but of the structure of subjective perception, so as to derive by logical consequence a system of sentences formally equivalent menaing sentences about physical objects in space and time.
