 Some philosophers who reject extensionalism nevertheless offer techniques for avoiding treating beliefs and desires as hyperintensional. Stalnaker (1984) tries to rescue the SPWS analysis of propositional content by explaining away hyperintensional intuitions via a sort of metalinguistic approach: when we fail to see that a proposition is necessarily true, or that two propositions are necessarily equivalent, we are actually failing to see what propositions are expressed by certain sentences. Given sentence \(A\), one should distinguish (1) the proposition \(P\) expressed by \(A\) (in a context), and (2) the proposition \(P\)* that A expresses \(P\), relating the sentence to what it expresses. Ignorance of necessary truths or equivalences is ignorance about P*.
