Full Idea

To be real in the scientific sense means to be an element of the system; hence this concept cannot be meaningfully applied to the system itself.

Gist of Idea

To be 'real' is to be an element of a system, so we cannot ask reality questions about the system itself

The 11 ideas from 'Empiricism, Semantics and Ontology'

Logical positivists incorporated geometry into logicism, saying axioms are just definitions [Carnap, by Shapiro]
Internal questions about abstractions are trivial, and external ones deeply problematic [Carnap, by Szabó]
Empiricists tend to reject abstract entities, and to feel sympathy with nominalism [Carnap]
Existence questions are 'internal' (within a framework) or 'external' (concerning the whole framework) [Carnap]
To be 'real' is to be an element of a system, so we cannot ask reality questions about the system itself [Carnap]
Questions about numbers are answered by analysis, and are analytic, and hence logically true [Carnap]
We only accept 'things' within a language with formation, testing and acceptance rules [Carnap]
New linguistic claims about entities are not true or false, but just expedient, fruitful or successful [Carnap]
No possible evidence could decide the reality of numbers, so it is a pseudo-question [Carnap]
A linguistic framework involves commitment to entities, so only commitment to the framework is in question [Carnap]
All linguistic forms in science are merely judged by their efficiency as instruments [Carnap]
