At the gates, we were stopped. A sergeant approached the post wagon and asked, "Who are you? Where are you from? Will you be staying long?" This is how those arriving at the gates of Berlin during Goethe's time were questioned. The luggage was searched, a pass was issued, but as soon as one arrived at the inn, they had to fill out the next control forms, this time from the police. However, those traveling with Bruno Preisendörfer as time travelers experience much more: for example, on November 7, 1775, at five in the morning, he stands in front of the house of a chamber court president named von Kalb in Weimar and watches Goethe's carriage roll over the cobblestones. He visits a philanthropic reform school or finds himself seated among the peasant children in the benches of a village school. He goes to the university to listen to Kant and Fichte; any difficulties in understanding need not be embarrassing for him.
