 Carnap’s own position on his 1956 criterion appears somewhat ambiguous. While he is reported to have accepted one set of criticisms (Kaplan 1975b), he also asserted even after they had been put to him that he thought his 1956 criterion remained adequate (1963b, §24b). Yet Carnap there also advised investigation of whether still another, then entirely new approach to theoretical terms that he was developing would allow for an improved criterion of significance for them. So when Carnap offered “the Ramsey method” as a method of characterizing the “empirical meaning of theoretical terms” it was not their empirical significance as such but the specific empirical import of theoretical terms that he considered (1966, Ch. 26). What prompted him to undertake his investigations of ramseyfications was not dissatisfaction with his 1956 proposal as a criterion of significance for theoretical terms, but the fact that it still proved impossible with this model to draw the distinction between synthetic and analytic statements in the theoretical language. The reason for this was that the postulates for the theoretical language also specify factual relations between phenomena that fall under the concepts that are implicitly defined by them. (As noted, a similar problem already had plagued Carnap’s analyses of disposition terms ever since he allowed for non-eliminative reduction chains.)
