 Second, Lewis does not give a particularly special place to the subject’s verbal behaviour in considering which content fits. In particular, we don’t first ask what assignment of contents to their words best makes sense of their verbal behavior, and then say that the central aspect of fit for mental states involves dispositions to produce words with the same contents as belief states. Rather, Lewis follows Grice (among others) in taking mental content to be metaphysically primary, and linguistic content to be determined by mental states (see the section on meaning in the entry on  Grice).
