I am reading a book which contains the following quote by Johann Wolfgang Von Goethe at the beginning of a chapter:
For him who seeks the truth, an error is nothing unknown.
What does it mean? In particular, what does "nothing unknown" mean?
For those who are curious about the context of this quote, it is in Chapter 5 "Randomized Algorithms" of the textbook "Algorithmics for Hard Computing Problems" by Juraj Hromkovič, and randomized algorithms typically allow the possibility of making mistakes as long as the error probability is small enough.
nicht eine unbekannte Sache
(not an unknown thing) normally contracts tokeine unbekannte Sache
(no thing unknown).
