Another solution to the problem of theoretical terms

Abstract

In this paper, a solution to the problem of theoretical terms is developed that is based on Carnap's doctrine of indirect interpretation of theoretical terms. This doctrine will be given a semantic, model-theoretic explanation that is not given by Carnap himself as he remains content with a syntactic explanation. From that semantic explanation, rules for the truth-value assignment to postulates, i.e. sentences that determine the meaning of theoretical terms, are derived. The logical status of postulates will be clarified thereby in such a way that the problem of theoretical terms disappears. © 2008 Springer Science+Business Media B.V.
