 The terms of the debate are not quite as simple as this implies. There is scope, for example, for a spectrum of views. Perhaps we should be idiolectal when thinking about language acquisition but not when thinking about the reference of proper names. Perhaps too we should recognize two kinds of linguistic content, only one of which—narrow content—is best thought of in idiolectal terms. Moreover, even someone taking a strongly idiolectal stance will want to qualify the definition of “idiolect” given above—by tying its properties to a person at a specified time, in a specified social setting, or on a specified occasion, for example, or by treating the idiolect as belonging not to a concrete individual speaker, replete with a suite of performance errors, but to a person who is in some respects an idealization and an abstraction.
