 While still doubting that Carston’s view can fully account for cardinals, Horn (1989: 250–1; 2010: 314–5) now concludes that they do not behave like quantifiers. For example, if you know that everyone passed, you must answer “Did some students pass?” with “Yes”. But if you know that Peter has two children, you cannot answer “Does Peter have one child?” without knowing whether the speaker meant “at least” or “exactly”. Indeed, a strong case can be made that (17) is ambiguous, so that Neo-Gricean and Relevance accounts are both wrong.
