My problem is the word "eingebildeter". I suppose it might means either fictitious or conceited, but I have a French translation that renders it "... manifestations d'un pouvoir cultivé mais, en réalité, depuis longtemps dépassé." What's "cultivé" got to do with "eingebildeter"? That's the question! Has the French translator a lot of eingebilter imagination?
