Rudolf Carnap – – Bobbs-Merrill. Carnap – – Revue Internationale de Philosophie 4: But to be meaningful is not the same as having ontolpgy meaning in the sense of an entity designated.

Our previous discussion concerning the acceptance of frameworks enables us now to clarify the situation with respect to abstract entities as designata.

The new entities are values of these variables; the constants are substitutable for the variables. One philosopher thinks numbers are real entities and that gives him the right to use the linguistic forms of the numerical framework and to make semantical statements about numbers as designata of numerals. Therefore nobody who meant the question “Are there numbers?

This shows again the confusion mentioned, rmpiricism a ontloogy or myth is a false or dubious internal statement. Carnap thinks there is no possible evidence that would be regarded as relevant by both philosophers to decide this controversy.

Are there properties classes, numbers, propositions? If they are given, they should be understood, not as ingredient parts of the system, but merely as marginal notes with the purpose of supplying to the reader helpful hints or convenient ontologg associations which may make his learning of the use of the expressions easier than the bare system of the rules would do.


No keywords specified fix it.

Above all, it must not be interpreted as referring to an assumption, belief, or assertion of “the reality of the entities. Wemantics Bradley – – Synthese 5: Revue Internationale de Philosophie 4 Carnap provides the following example of this problem of proof:. A physicist who is suspicious of abstract entities may perhaps try semantucs declare a certain part of the language of physics as uninterpreted and uninterpretable, that part which refers to real numbers as space-time coordinates or as values of physical magnitudes, to functions, limits, etc.

Empiricism, Semantics and Ontology

Problems and Changes in the Empiricist Criterion of Meaning. These questions are to be answered by empirical investigations.

In the case of mathematics some empiricists try to find a way out by treating the whole of mathematics as a mere calculus, a formal system for which no interpretation is given, or can be given. The history of science shows examples of such prohibitions based on prejudices deriving from religious, mythological, metaphysical, or other irrational sources, which slowed up the developments for shorter or longer periods of time.

And the same holds for references to abstract entities as designata in semantics.

The restriction to rational coordinates would not be in conflict with any experimental knowledge we have, because the result of any measurement is a rational number.

The acceptance cannot be judged as being either true or false because it is not an assertion.

Empiricism, Semantics, and Ontology. —

The new entities are the space-time points. We accept the thing language with its framework which enables us to ask and answer internal questions like “Is there a white piece of paper on my desk? But this demand for theoretical justification is wrongly applied to the acceptance of a system of entities. But these questions cannot be identified with the question of realism.

Carnap, “Empiricism, Semantics, and Ontology”

The acceptance of the thing language leads on the basis of observations made, also to the semanics, belief, and assertion of certain statements. As far as it is a principle of accepting certain entities and not accepting others, leaving aside any ontological, phenomenalistic and nominalistic pseudo-statements, there cannot be any theoretical objection kntology it. They usually feel much more in sympathy with nominalists than with realists in the medieval sense.


Although characterizations of these or similar kinds are, strictly speaking, unnecessary, they may nevertheless be practically useful.

On the other hand, the external questions of the reality of physical space and physical time are pseudo-questions. Kane – – International Philosophical Quarterly 7 1: Further, the general term “proposition” is introduced. Semantics, Empiricism, and Ontology. An assertion of this kind would indeed be semantisc dubious psychology. The spatio-temporal coordinate system for physics.

However, we have seen that the external question is not a theoretical question but rather the practical question whether or not to accept those linguistic forms. Thus, according to this way of thinking, the existence of abstract entities could be asserted only if one could show either that some abstract entities caarnap within the given, or that abstract entities ontologgy be defined in terms of the types of entity which are given.

The distinction I have drawn in the latter book between the method of the name-relation and the method of intension and extension is not essential for our present discussion. Second, the introduction of variables of the new type. To accept the empiricims world means nothing more than to accept a certain form of language, in other words, to accept rules for forming statements and for testing accepting or rejecting them.

I will briefly summarize this framework again:
