Dear Teachers,

I read this from True Pleasures by Lucinda Holdforth:

"German women rarely show the quick spirit which makes conversation live and ideas move. This kind of pleasure can only be found in the wittiest, most piquant Parisian society. You need the elite of a French capital for such rare entertainment."

What does "quick" mean in this context?
And, since it is "a French capital" instead of "the French capital", I suppose this does not refer to Paris. Then what does "the elite of a French capital" mean?
