Bolstering the latter suggestion are cases involving what Thomas Hofweber (1999, 98ff.) calls “hidden relativity”. For example, according to Hofweber, our claim, “August is a summer month,” presumes that we are in the Northern hemisphere.[17] A speaker may not be aware of this, however; and even those who are aware of it do not feel compelled to make that parameter explicit whenever they utter the relevant sort of sentence. So, when Schiffer says, “no ordinary person would dream of telling you that what he meant and was implicitly stating was that he knew that p relative to such-and-such standard” (1996, 326ff.), that in itself does not show that no such relativization is in play.
