Clearly the author means "revived in modern intellectual discourse in the English language". And some of them already have, e.g. eudaimonia as described by the ancient Greeks is brought up all the time in the literature on "positive psychology".

It wasn't very clear to me, as "revive" has a connotation of "in the context it originally was". If I said "we should revive the dodo" I wouldn't immediately imagine a US zoo.
