 A different sort of worry about a theory of this sort is that the requirement that we maximize the truth of the utterances of subjects hardly seems sufficient to determine the meanings of the expressions of their language. It seems plausible, offhand, that there will be many different interpretations of a subject’s language which will be tied on the measure of truth-maximization; one way to see the force of this sort of worry is to recall the point, familiar from our discussion of possible worlds semantics in  §2.1.5  above, that a pair of sentences can be true in exactly the same circumstances and yet differ in meaning. One worry is thus that a theory of Davidson’s sort will entail an implausible indeterminacy of meaning. For Davidson’s fullest attempt to answer this sort of worry, see Chapter 3 of Davidson (2005).
