 We’ll follow Perry in using English sentences to identify particular such doxastic states. So, for example, the “my pants are on fire” doxastic state is the cognitive state underwriting dispositions to sincerely assert “my pants are on fire”, to seek out fire extinguishers and turn them on one’s lower parts, etc., which according to Perry is a matter of being in a belief-state whose character mirrors that of the English sentence, and according to Lewis is a matter of standing in the belief relation to the property one needs to instantiate in order to speak truly with the sentence, given the sentence’s actual character (or standing in the belief relation to the corresponding centered-worlds proposition).
