I deal with the cognitive states expressed by de dicto logically complex sentences–those that are expressives, such as negations, disjunctions, universal noun phrase sentences, and adverbs of generality. I also articulate more clearly STA’s expressivism about semantic norms and its psychologism: the account of how sentences express cognitive states is integral to the semantics that STA gives of them.
