Volksgeist (spirit of a culture) vs zeitgeist (spirit of the times) vs weltgeist (spirit of the world) - all very idealistic in essence....but not always in application.
Today, less idealistic, as we are in a grippezeitgeist. I like how flu is grippe. It sums up the spirit of the illness. Angstgeist! The weltwirtschaftgeist is under siege.
I'm sure the above is all a bit slightly wrong. But, invention is fun. It all seems much more mundane in english - "mood/spirit of the world economy" seems downright dull in comparison to weltwirtschaftgeist. Which, in character, seems to carry more of an inherent warning.
