Abstract
What is it to understand another speaker’s utterance? A natural view is that such understanding requires at least the acquisition of propositional knowledge of the utterance’s meaning. This view is challenged by cases in which it correctly seems to a hearer H as though an utterance means such-and-such, but where H doesn’t form the belief that it means such-and-such due to a misleading defeater. Such cases have been claimed to be examples of understanding without belief, and a fortiori of understanding without knowledge. The paper examines this argument in detail and defends a mixed verdict: While the argument succeeds in showing that there is a reading of attributions of utterance understanding on which the natural view is false, such attributions also have a different reading on which the natural view may well be true for all the argument shows. In making the case for the second half of this claim, the paper gives center stage to the close intuitive connection between utterance understanding and communicative success.
