 Finally, though we shall not go into it here, it is worth mentioning that when Zalta gets to the semantics of verbs of propositional attitudes, it is not only the propositions considered thus far that are objects of the attitudes and make belief ascriptions true or false. Zalta ends up claiming that sentences embedded with respect to attitude verbs are ambiguous, sometimes expressing the sorts of propositions we are discussing, and sometimes expressing other propositions that instead of containing the individuals, properties and relations thus far discussed, contain senses of these individuals, properties and relations. These senses are “abstract” individuals and relations, instead of the ordinary individuals and relations discussed thus far. Hence Zalta ends up with a theory of belief ascriptions that invokes both fine-grained propositions and neo-Fregean senses. The interested reader should consult Zalta [1988].
