Abstract

Context Shifting Arguments (CSA) ask us to consider two utterances of an unambiguous, non-vague, non-elliptic sentence S. If the consensus intuition is that what’s said, or expressed or the truth-conditions, and so possibly the truthvalues, of these utterances differ, then CSA concludes S is context sensitive. Consider, for example, simultaneous utterances of ‘I am wearing a hat’, one by Stephen, one by Jason. Intuitively, these utterances can vary in truth-value contingent upon who is speaking the sentence, while holding hat-wearing constant, and so they express distinct propositions and differ in their truth conditions. Since these differences are not the result of ambiguity (lexical or structural), vagueness, conversational implicature, or syntactic ellipsis, we have pretty strong evidence that ‘I am wearing a hat’ is context sensitive.
