@OmSigDAVID,
Zeitgeist today and especially in American English might have a different mena to the German word "Zeitgeist".
Herder translated a very popular book title of his time, "
Genius Saeculi" to the new German word "Zeitgeist".
His owb definition of Zeitgeist was
herrschenden Meinungen, Sitten und Gewohnheiten einer Zeit (1793) - "prevailing opinions, customs and habits of a time".
That's why we only speak of a Zeitgeist retrospectively.
