Carnap sought to give a logical formulation of this principle. Der Raum deals with the philosophy of space.

Carnap, Rudolf | Internet Encyclopedia of Philosophy

Physical space is synthetic a posteriori; it is the object of natural science, and we can know its structure only by means of experience. According to Catnap, this word has lost its primary, naive meaning but failed to acquire any other.

As a result, the set of analytic statements which are a logical consequence of the Carnap sentence is the smallest set of analytic statements. The Analysis of Philosophy in Logical Syntax: Carnap’s formulation of modal logic is very important from a historical point of view.

A is called “intensional with respect to p” if and only if i A is not extensional with respect to p and ii the truth elimunation A does not change if we substitute the sentence p with a logically equivalent sentence q. Now propositions that do not belong to any one of these classes are devoid of all sense.

In Meaning and Necessity. Carnap thus defines analytic statements as logically determined statements: Note that every empirical statement that can be derived metaaphysics the Carnap sentence is logically true, and thus the Carnap sentence lacks empirical consequences. Philosophical Foundations of Physics is a clear and approachable survey of topics from the philosophy of physics based on Carnap’s university lectures.


Wojcicki and Przelecki’s research is independent of the distinction between observational and theoretical terms, i. A scientific explanation is thus a logical derivation of an appropriate statement from a set of premises, which state universal laws and initial conditions.

Bridgman asserted that the curvature of space-time, a concept used by Einstein in his general theory of relativity, is meaningless, because it is not definable by means of operations. Of course, we cannot be sure that an hypothesis is true; but we can evaluate its degree of confirmation and we cwrnap thus compare alternative theories.

Rudolf Carnap (1891—1970)

wlimination Carnap tried to employ the physical-mathematical theory of thermodynamic entropy to develop a comprehensive theory of inductive logic, but his plan never progressed beyond an outline stage. Therefore modern logic has clarified that existence is not a predicate, and has revealed the logical error from which pseudo-statements such as “cogito, ergo sum” arose.

They are symbols denoting physical entities, properties or relations such as ‘blue’, ‘cold’, ‘ warmer than’, ‘proton’, ‘electromagnetic field’. Let A be a sentence in which another sentence occurs, say eilmination.

Intuitive space, with its synthetic a priori character, is a concession to Kantian philosophy.

On Carnap’s Elimination of Metaphysics

The first and the last books Carnap published during his lifetime were concerned with the philosophy of physics: In The Logical Structure of the World he asserted that a statement is meaningful only if every non-logical term is explicitly definable by means of a very restricted phenomenalistic language. A few years later, Carnap realized that this thesis was untenable because a phenomenalistic language is insufficient to define physical concepts.

The latter sets out Carnap’s definitive view on the analytic-synthetic distinction. In some ways the distinction between observational and theoretical terms cwrnap similar to that between macro-events, which are characterized by physical quantities that remain constant over a large portion of space and time, and micro-events, where physical quantities change rapidly in space or time.

Ralph Dumain: “The Autodidact Project”: V. Brushlinsky: Carnap’s ‘Elimination of Metaphysics’

Rudolf Carnap was born on May 18,in Ronsdorf, Germany. Some theories expressed there are not those of Carnap alone, but they belong to the common heritage of logical empiricism.

All other terms biological, psychological, cultural must be defined by means of basic terms. Political Philosophy of Science in Logical Empiricism: Embedded in this essay is the article by V. Under what conditions is S supposed to be true, and under what conditions false? One of the main purposes of the philosophy of science is to show the difference between the various kinds of statements. It can explain and forecast facts and be thought of as an inductive generalization of such factual metalhysics.

Another source of elimintion is type confusion, in which a predicate is used as predicate of a different type see the example “Caesar is a prime number”. Carnap was also interested metaphysisc formal logic Introduction to Symbolic Logicand in elimibation logic Logical Foundations of Probability; The Continuum of Inductive Methods Another interesting example is the explanation of belief-sentences which Carnap gave in Meaning and Necessity.

In Carnap’s inductive logic, the probability of every universal law is always zero. As a sample of the content of Philosophical Foundations of Physics we can briefly look at Carnap’s thought on scientific explanation.
