 Carnap introduced a distinction between questions that are internal to a framework and questions that are external to a framework (Carnap 1950). It has been argued that Carnap’s distinction in some guise survives the demise of the logical empiricist framework in which it was first articulated (Burgess 2004b). Tait has attempted to work out in detail how the resulting distinction can be applied to mathematics (Tait 2005). This has resulted in what might be regarded as a deflationary versions of platonism.
