ABSTRACT
Recall the program-scope gap from Part I. I described it as a split between what we say (our scientific theories and what they range over) and what we do (successful application of theory). This split also lives among the rarified idioms of truth and reference. One way to see why this would be is to recognize that these idioms are part of an (applied) theory of language that has been mathematized in recent years (analogously to how folk physics was mathematized centuries ago). The program-scope gap arises in disguise, though: as philosophical puzzles about naturalizing reference.
