 Concerning the criticism of the circular nature of the definition of analyticity, Carnap responded that it pertained primarily to the idea of analyticity in natural language whereas he was interested in “explications” as provided by the logic of science (or better, a logic of science, since there existed no unique logic of science for Carnap). Explications are reconstructions in a formal language of selected aspects of complex terms that should not be expected to model the original in all respects (1950b, Ch.1). Moreover, Carnap held that explication of the notion of analyticity in formal languages yielded the kind of precision that rendered the complaint of circularity irrelevant: vague intuitions of meaning were no longer relied upon. Those propositions of a given language were analytic that followed from its axioms and, once the syntactic limitations of the Logical Syntax period had been left behind, from its definitions and meaning postulates, by application of its rules: no ambiguity obtained.
