Grice's new precept: meaning t≠ use (WoW:2)

Grice refers to the old precept:

"meaning = use"

and the new precept:

"meaning ≠ use"

---

On p. 2 of WoW he confesses to being

"more sympathetic to the

new precept than the old."

--- hence his "Modified Occam's razor", one hopes -- and in fact, the whole idea of "Conversational Implicature"!
