Curiously enough it was at this same period that came his revulsion toward the dissipations of student life. He went so far as to attempt an imposition of his moral theories on the members of the Franconia, but this attempt at reformation resulted only in his own unpopularity. In his attitude toward duelling--a pastime somewhat over-emphasised at Bonn--Nietzsche was consistent with his other beliefs. The chivalrous side of it appealed to him, although he detested the spirit of it from the standpoint of the student body. However, he took heroic, if unconventional, means to involve himself in a duel lest his position be misconstrued as cowardice. He selected an adversary he thought worthy of him, and pleasantly demanded a combat on the field of honour, ending his request: "Let us waive all the usual preliminaries." The other agreed, and the duel was fought. But the incident merely resulted in emphasising Nietzsche's disgust for student life. Says his sister, "The circumstances which above all aroused my brother's wrath was the detestable 'beer materialism' with which he met on all sides, and owing to these early experiences in Bonn he for ever retained a very deep dislike for smoking, drinking, and the whole of so-called 'beer-conviviality.'" His decision to leave Bonn and enter the University of Leipzig was due to his fondness for Ritschl. In the dispute which arose between the two Professors, Jahn and Ritschl, Nietzsche's friendship for the latter made him a partisan, although he held Jahn in the highest respect; and when Ritschl decided to transfer himself to Leipzig, the young philosopher, along with several of the other students, followed him. This was in the autumn of 1865. Nietzsche reached Leipzig on the 17th of October, and the next day he presented himself to the Academic Board. It was the centennial anniversary of the day when Goethe had entered his name on the register, and the University was celebrating the event. The coincidence delighted Nietzsche greatly, who regarded it as a good omen for his future at the new institution.
