Smith: "Ch. 14 is on the Arithmetization of Syntax. It is difficult to do this stuff with a light touch, and (as elsewhere in OLT) I’d go for adding quite a lot more arm-waving motivation, here along the lines of “Look, consider the relation Pr(p, n) which holds when p codes for a well-formed proof in Q of the wff with number n. It’s easy to see that you can check whether Pr(p, n) without going in for any open-ended searches; here, informally, is how. So Pr is going to be primitive recursive, right?”"
