 With appropriate extrapolation, then, Lewis’s main tenets may be perfectly compatible with Davidson’s own description of these supposedly troublesome cases. Even in cases of malapropism, speaker and hearer are trying to solve a coordination problem by using a common language L (i.e., a common passing L, a common open or dynamic L, or a common set of sufficiently similar Ls) in a way that observes the conventions of truthfulness and trust. Of course, Lewis must include some form of general explanatory reasoning, thereby contradicting his apparent assumption that successful uses of L are fully systematic (or compositional). Yet it is worth considering how damaging this would be for Lewis’s account. It seems clear that something like Lewis’s theory (including some appropriately weakened version of his compositionality assumption, such as that developed in García-Ramírez 2019), will be needed.
