Abstract: This talk is a comparison of how different approaches to hyperintensionality, aboutness and subject matter treat (classically) logically equivalent statements. I compare and contrast two different notions of subject matter that might be thought to be representational or truth first – Aboutness (Princeton University Press, 2014), and truthmakers conceived of as situations, as discussed in my “Truthmakers, Entailment and Necessity.” I contrast this with the kind of inferentialist account of hyperintensionality arising out of the proof invariants I have explored in recent work.

This is a talk presented at the Hyperintensionality Afternoon, held by Francesco Berto’s project on the Logic of Conceivability.
