"M. Davidson, tongue in cheek (or cheek in jowl) is referring to an
interesting review in the NYT about a current exhibit on my favourite NYC street: the fifth, and by Maria Callas' former lover. It's an informative review, and for the rhetoric of it, the writer (a male) reminds us of another exhibit that M. Davidson was lucky to see -- with the Krytos boy into the bargain. What I want to focus here, since Davidson speaks of cliches, and this may be a good one to analyse:
"The Glory that Was Greece". Is the implicature -- but "no more"? The analysis of this type of implicature relies on work by Philo the Megarian, but I will leave today M. Chase to elaborate on this. Or not.
