 Another strategy involves resisting the argument at CH2, by maintaining that there are constraints beyond charity that favor the demanding interpretations. Charity, after all, is not the only factor involved in determining the meanings of our utterances. Certain puzzles about content determination have been thought to show that the content of an expression or utterance cannot be determined solely by which sentences we are inclined to regard as true; it is also partly a matter of the relative “naturalness” or “eligibility” of candidate contents. One who accepts this sort of account may maintain that the demanding interpretations, although less charitable, nevertheless assign more natural contents to English sentences than the liberal interpretations, for instance by assigning a more natural meaning to the  quantifiers.[63]
