Howard Wettstein, "Has Semantics Rested on a Mistake?"

Frege's criterion of adequacy for semantic theory is that it register differences of cognitive significance. New theories of reference do not meet Frege's criterion of adequacy, and attempts by new theorists like Kaplan and Perry to satisfy the criterion by employing "character" or "role" fail to do justice to Frege's data. The proper response for new theorists of reference is to reject Frege's criterion of adequacy. Belief reports do not favor either Fregeans or new theorists.
