 For Carnap, each statement in a linguistic framework should have a truth value that can be determined either by analytical or empirical methods. A statement’s truth value is analytically determinable if it is logically true (or false), or if it’s truth is determinable exclusively from the rules of the language or on the basis of semantic relationships among its component expressions. A statement is empirically determinable when it is confirmable (or disconfirmable) in the light of the perceived evidence. Note that the very attempt to confirm an empirical statement about physical objects on the basis of the evidence requires that one adopt the language of the framework of things. Carnap warns us, however, that “this must not be interpreted as if it meant … acceptance of a belief in the reality of the thing world; there is no such belief or assertion or assumption because it is not a theoretical question” (1950 [1956, 208]). For Carnap, to accept an ontology “means nothing more than to accept a certain form of language, in other words to accept rules for forming statements and for testing, accepting, or rejecting them” (1950 [1956, 208]).
