Disimplicature

Speranza

Grice engages with the literature that has tried to distill the significance of Frege's context principle for the philosophy of language (setting aside its role in Frege's argument for mathematical platonism). 

Grice argues that there are some interpretive problems with recent meta-semantic interpretations of the principle. Instead, Grice offers a somewhat weaker alternative: the context principle is a tool to license certain definitions. Moreover, Grice claims that it merely lays out one of many possible ways of licensing a definition. 

Despite Frege's imperative injunctions, we should take it to be a permission statement, not an obligation.
