After a brief summary of the questions at issue in that earlier dialogue, Carnap* is here allowed a final reply, introducing yet another variant on his series of more precise formulations of the linguistic doctrine of logical truth and touching on other issues raised both by Quine* in the earlier dialogue and by Quine himself in his reply.
Given dominant professional formations, this fact has by and large had to be and has been repressed within academic philosophy, as instead the book has been mined for its doctrines concerning such things as the nature of the proposition, logical truth, and the nature of the logical connectives.

Ben-Menahem argues that Quine despairs of the possibility of grounding logical truth in a finite number of explicit conventions, (4) associates realism with the grammar of "true," construes conventionalism as sanctioning the stipulation of truth, describes the notion of truth by convention as itself a metaphor, draws attention to the interplay between the conceptual and the empirical, clarifies the desirability of organizing schemata around material appearances of terms, and wields his regression argument to challenge the conventionalist account qua explanation of logic.
