From the link provided by R. Paul (under a different thread):
"The academy has yet to reveal who will deliver Dylan's speech."
McEvoy might say the utterance is ambiguous.
i. The academy has yet to reveal who will deliver Dylan's speech.
It's by Mr. Savage, and one should distinguish (i) from (ii):
ii. The Academy has yet to reveal who will delivery Dylan's speech.
It might be argued that this is NOT Plato's Academy, for the revelation would
then perhaps be a matter of some oracle or other from Delphi.
It might also be argued (philosophy is all about arguing) that, by what
logicians call the theorem of elimination, Popper or Grice will not be
delivering Dylan's speech. The 'entailment,' rather than implicature, of (i)
seems to be:
iii. Dylan will not be delivering his speech.
Again, this is arguable -- and (iii) might be deemed an 'implicature,' in that
it is cancellable:
iv. The academy has yet to reveal who will deliver Dylan's speech, if not Dylan
his self. For although he did say he had 'pre-existing commitments,' as Pyrrho
said, 'you never know.' We'll have to wait and see -- and listen, strictly.
Cheers,
Speranza
