Empiricism, Semantics, and Ontology. Rudolph Carnap. [In this essay Carnap is concerned with the question of the “reality” of the sorts of what he calls “abstract. Rudolf Carnap’s article “Empiricism, Semantics, and Ontology” deals with the implications of accepting language which refers to abstract entities. Empiricists. Carnap, “Empiricism, Semantics, and Ontology”. Major Premise: Accepting the existence abstract entities involves a pragmatic decision to use a certain linguistic.

empiticism Shamik Dasgupta – – Philosophical Review 3: We apply the term ‘proposition’ to any entities of a certain logical type, namely, those that may be expressed by declarative sentences in a language” p. This evaluation is usually carried out, of course, as a matter of habit rather than a deliberate, rational procedure. The prehistory of the theory of distributions.

Certain early British empiricists e. The Journal of Symbolic Logic. Carnap and ontological pluralism”.

The efficiency, fruitfulness, and simplicity of the use of the thing language may be among the decisive factors. Such a characterization is analogous to an extra-systematic explanation which a physicist sometimes gives to the beginner. The Problem of Universals. What Quine meant by ‘subclass’ questions se,antics questions like “what are so-and-so’s? The acceptance cannot be judged as being either true or false because it is not an assertion.

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 e,piricism about numbers as designata of numerals. Or onfology, it may be meant in the seantics sense: He says that the acceptance and use of thing language should not be interpreted as meaning that one believes in the reality of the thing world, but merely as an acceptance of a certain form of language; to accept rules for forming statements and for testingaccepting, or rejecting them.


A physicist who is suspicious of abstract entities may perhaps try to 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.

The following three constructs are included within this framework: Thus the logical characteristics of this framework are sufficiently clear while many internal questions, i. And now we must distinguish two kinds of questions of existence: Thus it is clear that if someone accepts the framework of numbers, then he must acknowledge c and b and hence a emiricism true statements.

The spatio-temporal coordinate system for physics.

New variables, “p,” “q,” etc. Semantivs granting freedom to use any form of expression which is useful, the work will sooner or later lead to the elimination of those forms which have no useful function.

The ghost who walks, p. This article has no associated abstract.

Empirciism critics will have to show that it is possible to construct a semantical ontologyy which avoids all references to abstract entities and achieves by simpler means essentially the same results as the other methods.

On what grounds what”. 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 to it.

Further, the general term “proposition” is introduced. Quantifier Variance and Realism: In fact, however, all that can accurately be said about atoms or the field is implicitly contained in the physical laws of the theories in question. Thus, for example, Ernest Nagel in his review 9 asks for “evidence relevant for affirming with warrant that there are such entities as infinitesimals or anf.

A true answer is either factually true, using empirical methods of analysis, or analytic, using logical methods. University of Chicago Press. Charles Landesman – – New York: References to space-time points, the electromagnetic field, or electrons in physics, to real or complex numbers and their functions in mathematics, to the excitatory potential or unconscious complexes in psychology, to an inflationary trend in economics, and the like, do not imply the assertion that entities of carnnap kinds occur as immediate data.


This article has no associated abstract. The system of empiriciism only had extended objects with spatial and temporal ontologh between them. It is important to notice that the system of rules for the linguistic expressions of the propositional framework of which only a few rules have here been briefly indicated is sufficient for the introduction of the framework.

What is now the nature of the philosophical question concerning the existence or reality of numbers? Eempiricism of Western Philosophy. This makes it plausible to assume that those philosophers who treat the question of the existence of numbers as a serious philosophical problem and offer lengthy arguments on either side, do not have in mind the internal question.

In spite of this warning, it seems that some of those readers who were puzzled by the explanations, did not disregard them but thought that by raising objections against them they could refute the theory. Propositions are not mental entities. However, let us look at a few different examples. See Rescorla, Michael Jan 13, Are there properties classes, numbers, propositions?

Empiricists have always been suspicious of abstract entities such as properties and numbers and try to stick to nominalistic language – to not have references to these entities. Therefore our judgment must be that they have not succeeded in giving to the external question and to the possible answers any cognitive content.
