  In sum, the problem with Davidson’s truth-theoretic proposal is much like the problem discussed above with Quine’s grammatical proposal. Without further constraints on the theory of meaning (or, in Quine’s case, the grammar), it does not yield a definite criterion for logical constancy. I do not mean to suggest that either Davidson or Quine was deluded on this score. As we saw above, Quine appeals to pragmatic considerations to pick out a favored language and grammatical regimentation. No doubt Davidson would do the same, arguing (for example) that the advantages of using a simple and well-understood logic in the metalanguage outweigh any putative advantages of treating “large” and the like in recursive clauses. (For a recent defense of a Davidsonian criterion against Evans’s objections, see Lepore and Ludwig 2002.)
