Further, as Hofweber says (1999, 101–2), with regard to ‘summer month’, say, there is a plausible explanation of why the relativization in question can be hidden for many speakers and, even among those who are aware of it, rarely be made explicit—namely, that most of the people with whom we discuss such things are geographically close to us. Because of this, the relativity to a hemisphere very rarely makes a difference to uses of ‘summer’. Whereas, the evidence for contextualism requires that there be some interesting variation among the standards which determine a ‘knowledge’ sentence’s truth-conditions within this or that linguistic community, and it requires that we be guided in our everyday “knowledge”-attributing behavior by an awareness of just this fact.
