On the one hand I was powerfully attracted by science, with its truths based on facts; on the other hand I was fascinated by everything to do with comparative religion. [...] In science I missed the factor of meaning; and in religion, that of empiricism.

I myself found a fascinating example of this in Nietzsche’s book Thus Spake Zarathustra, where the author reproduces almost word for word an incident reported in a ship’s log for the year 1686. By sheer chance I had read this seaman’s yarn in a book published about 1835 (half a century before Nietzsche wrote); and when I found the similar passage in Thus Spake Zarathustra, I was struck by its peculiar style, which was different from Nietzsche’s usual language. I was convinced that Nietzsche must also have seen the old book, though he made no reference to it. I wrote to his sister, who was still alive, and she confirmed that she and her brother had in fact read the book together when he was 11 years old. I think, from the context, it is inconceivable that Nietzsche had any idea that he was plagiarizing this story. I believe that fifty years later it has unexpectedly slipped into focus in his conscious mind.
