 As Carnap understood the analytic/synthetic distinction, it was a distinction drawn by a logician to enable greater theoretical systematicity in the reconstructive understanding of a given symbol system, typically a fragment of a historically developed one. That fully determinative objective criteria of what to regard as a logical and what as a non-logical term cannot be assumed to be pre-given does not then in and of itself invalidate the use of that distinction by Carnap. On the contrary, it has been convincingly argued that Carnap himself did not hold to a notion of what is a factual and what is a formal expression or statement that was independent of the specification of the language in question (Ricketts 1994). The ultimate ungroundedness of his basic semantic explicatory categories, this suggests instead, was a fact that his own theories fully recognized and consciously exploited. (Somewhat analogously, that we cannot define science independently of the practice of scientists of “our culture” was admitted by Neurath 1932a, Carnap 1932d and Hempel 1935, much to the exasperation of Zilsel 1932 and Schlick 1935a.)
