 Now, Davidson presents us with a case where antecedent knowledge of L is not enough to guarantee communication and, hence, to solve the coordination problem that Lewis has in mind. Yet, there clearly is a way in which speakers manage to solve the coordination problem even in cases of malapropisms. Davidson suggests that this is done in virtue of using non-linguistic knowledge (e.g., using practical reasoning, explanatory reasoning, etc.). To see if such uses of L really constitute a counterexample to Lewis’s position we must ask ourselves if, in solving this coordination problem, speaker and hearer do observe the conventions of truthfulness and trust in L, or if they simply reject them in order to successfully communicate.
