Turing and Grice: The Implicature Game: a guide to codes and ciphers

Speranza

Variations on Grice's example:

A: I'm out of fuel.
B: There's a station around the corner.

Rdically, Bob might have been using

 

“There’s a station around the

corner” in a secret code known only to Bob and Ann, in which the sentence

meant that Bob has a can of gasoline in his trunk.

 

In that case, consistency with

the Maxim of Quality would require Bob to believe he has a can of gasoline in his

trunk, and consistency with the Maxim of Relation would require him to believe

Ann can use that gasoline (Davis 1998 pg.64).

What is important as an operative background constraint is not conventional word

meaning but what the utterer meant by the sentence she uttered.
Turing would agree.
