“The nineteenth century was the Age of Romanticism; for the first time in history, man stopped thinking of himself as an animal or a slave, and saw himself as a potential god. All of the cries of revolt against 'God' - De Sade, Byron's "Manfred", Schiller's "Robbers", Goethe's "Faust", Hoffmann's mad geniuses - are expressions of this new spirit. Is this why the 'spirits' decided to make a planned and consistent effort at 'communication'? It was the right moment. Man was beginning to understand himself.”
