Rudolf Carnap, Empiricism, Semantics and Ontology – PhilPapers

No keywords specified fix it. The problem of the legitimacy and the status of abstract entities has recently again led to controversial discussions in connection with semantics. This article has no associated abstract. The critics will have to show that it is possible to construct a semantical method which avoids all references to abstract entities and achieves by simpler means essentially the same results as the other methods.

It may be meant as an internal question; then the affirmative answer is, of course, analytic and trivial. There is a particular kind of misinterpretation of the acceptance of abstract entities in various fields of science and in semantics, that needs to be cleared up. History of Western Philosophy.

Richard Boyd – – Philosophical Studies 61 1: The Problem of Universals. Science Logic and Mathematics. Certain early British empiricists e. In physicsit is much more difficult to eliminate these dreaded entities. Carnap – – Revue Internationale de Philosophie 4: The third may mean “There are propositions” – which can be analytic, but if meant in an external sense, it is, according to Carnap, non-cognitive.

The physical state of a spatio-temporal point or ontologg is described either with the help of qualitative predicates e. However, none of those alternatives are practical, and that is Carnap’s point.

What is now the nature of the philosophical question concerning the existence or reality of numbers? Unless and until they supply a clear cognitive interpretation, we are justified in our suspicion that their question is a pseudo-question, that is, one disguised in the form of a theoretical question while in fact it is a non-theoretical; in the present case it is the practical problem whether or not to incorporate into the empiricizm the new linguistic forms which constitute the framework of numbers.


Sign in Create an account. If these philosophers regarded the acceptance of a system of entities as a theory, an assertion, they were victims of the same old, metaphysical confusion.

And the questions concerning these qualities are indeed of a theoretical nature. It is obvious that the apparent negation of a pseudo-statement must also be a pseudo-statement. This acceptance is not in need of a theoretical justification except with respect to expediency and fruitfulnessbecause it does not imply a belief or cadnap.

For example, the choice of real numbers rather than rational numbers or integers as coordinates is not much influenced by the facts of experience but mainly due to considerations of mathematical simplicity. Another strong hang-up empiricists have is with the concept of designation.

If someone decides to accept the thing language, there is no objection against saying that he has accepted the world of things. They reject the belief, which they regard as implicitly presupposed by those semantical statements, that to each expression of the types in question adjectives like “red,” numerals like “five,” etc.

Empiricists are in general rather suspicious with respect to any kind of abstract entities like properties, classes, relations, numbers, propositions, etc. Physics In our last example, the new entities are space-time points in the spatio-temporal coordinate system for physics. Realism and the Absence of Value. Empiricism, Semantics, and Ontology.

A brief historical remark may here be inserted. Two Kinds of a Priori Infallibility. Propositions are not mental entities.

Each is an ordered quadruple of four real numbers, called its coordinates, semanics of three spatial and one temporal coordinates. A general term, a predicate of a higher level, is introduced into the framework, so we can say of any particular entity that it belongs to this kind e.

Empiricism, Semantics and Ontology

An external question is of a problematic character which is in need of closer examination. With the help of the variables, general sentences about the new entities can be formulated e. However, it would prevent the use of ordinary geometry which says, e. The latter is the ajd given by Gilbert Ryle 8 to the criticized darnap, which, in his e,piricism, arises by a naive inference of analogy: 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.


But the thesis of the reality of the thing world cannot be among these statements, because it cannot be formulated in the thing language or, it seems, in any other theoretical language.

From these new language forms, one can formulate internal empirical empiricsim logical questions and possible answers to them.

Only entities belonging to a type of which examples were to be found within immediate experience could be accepted as ultimate constituents of reality.

The empirixism from the system of things which does not contain space-time points but only extended objects with spatial and temporal relations between them to the physical coordinate system is again a matter of decision.

Those who criticize these statements do not, of course, reject the use of the expressions in question, like “red” or “five”; nor would they deny that these expressions are meaningful. Sign in to use this feature. But it is possible, in a rational reconstruction, to lay down explicit rules for the evaluation. In fact, of course, the semanticist does not in the least assert or imply that the abstract entities to which he refers can be experienced as immediately given either by sensation or by a kind of rational intuition.

While “Fido” is a name, expressions like “red,” “five,” etc. Therefore every sentence of the form “. They usually feel much more in sympathy with nominalists than em;iricism realists in the medieval sense. Let us take as an example the statement:. We disregard here the fact that the rules of English grammar require not a sentence but a that-clause as emoiricism subject of another sentence; accordingly instead of a we should have to say “That Chicago is large is a proposition.

It is not a question simply of yes or no, carap a matter of degree.
