I recall a quote of the sort "Facts are the enemy of truth" attributed to Miguel de Cervantes in his book Don Quijote de la Mancha. However, I could not find the quote in the book by searching for "truth" or "enemy". There are also some sources on the web claiming the quote, such as here, here, or here.
Is there an actual passage in the book which conveys the meaning of the above quote? Or is this a total misattribution?
