 Notably, Sneed’s criterion of T-theoreticity suggests a strategy that allows us to regain a global, non-relativized theory-observation distinction: simply take a term t to be theoretical if and only if it holds, for all methods m of determining its extension, that m rests upon some axiom of some theory T. A term t is non-theoretical, or observational, if and only if there are means of determining its extension, at least in part, that do not rest upon any axiom of any theory. This criterion is still relative to our present stage of explicit theories but comes closer to the original intention of Carnap’s theory-observation distinction, according to which observation is understood in the narrow sense of unaided perception.
