A true answer is either factually true, using empirical methods of analysis, or analytic, using logical methods. In physicsit is much more difficult to eliminate these dreaded entities. But if this conception leads to the view that other philosophers or scientists who accept abstract entities thereby assert or imply their occurrence as immediate data, then such a view must be rejected as a misinterpretation.

From the internal questions we must clearly distinguish external questions, i. With these new forms in the language, you can now devise empirical or logical questions and possible answers to them.

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? Marc Alspector-Kelly – – Philosophical Studies 1: These are answered by empirical investigations, their results evaluated according to certain rules as confirming or disconfirming evidence for possible answers.

However, none of those alternatives are practical, and that is Carnap’s point. On the other hand, the external questions of the reality of physical space empiricismm physical time are pseudo-questions. You must accept these as true statements if you accept the framework of numbers. These questions are to be answered by empirical investigations.

I said that the term “proposition” “is used neither for a linguistic expression nor for a subjective, mental occurrence, but rather for something objective that may or may not be exemplified in nature. The numerals may still be used as meaningful expressions.

Among those philosophers who have carried out sfmantics analyses and thought about suitable tools for this work, beginning with Plato and Aristotle and, in a more technical way on the basis of modern logic, with C. For example, are propositions mental events as in Russell’s theory? But to be meaningful is not the same as having a meaning in the sense of an entity designated. From these questions we must distinguish the external question of the lntology of the thing world itself.

Kane – – International Philosophical Quarterly 7 1: Peirce and Frege, a great majority accepted abstract entities.

Thus the question of the admissibility of entities of a certain type or of abstract entities in general as designata is reduced to the question of the acceptability of the linguistic framework for those entities. It only means acceptance of the new framework ; i.

Carnap – – Revue Internationale de Philosophie 4: It is not a question simply of yes or no, but a matter of degree.

Above all, it must not be interpreted as referring to an assumption, belief, or assertion of “the reality of the entities. Charles Landesman – – New York: The problem of the legitimacy and the status of abstract entities has recently again led to controversial discussions in connection with semantics. But this demand for theoretical justification is wrongly applied to the acceptance of a system of entities.


But if so, they will have to offer better arguments than they have so far. 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 propositions.

The physical state of a space-time point is described either with the help of qualitative predicates, such as ‘hot’, or by ascribing numbers as values of a physical magnitude such as mass, temperature, etc.

Logical Empiricists on Race. In the case of mathematics some empiricists try to find a way out ontokogy treating the whole of mathematics as a mere calculus, a formal system for which no interpretation is given, or can be given. The fact that in these statements no reference to a subject an observer or knower occurs nothing like: The non-cognitive character of the questions which we have called here external questions aemantics recognized and emphasized already by the Vienna Circle under the leadership of Moritz Schlick, the group from which the movement of logical empiricism originated.
