 On this reading of Husserl’s notion of the determinable X, there is a link, at least in the case of proper names and in the ubiqituous indexical case, between intentional content (including determinable X) on the one hand, and extra-mental reality on the other, such that intentional content thus understood determines reference in much the same way more recent externalist theories of content would have it, i.e. in such a way that the referent can in turn be said to help determine the intentional content (see Beyer 2000, 2001; cf. also Husserl’s discussion of Twin Earth in Husserliana, vol. XXVI, p. 212). Notice, however, that Husserl does not naively take the existence of an extra-mental referent for granted. Instead, he asks which structures of consciousness entitle us to represent the world as containing particular objects transcending what is currently given to us in experience (see Sections 7 and 8 below).
