The Library of Every Possible Book
Borges imagines a library of identical hexagonal galleries whose books contain every possible arrangement of 25 orthographic symbols across 410 pages, so it holds every true history, every refutation of it, and the catalogue of the library alongside countless false catalogues. The librarians who live there swing between euphoria at knowing that every answer exists and despair, because nearly every volume is gibberish and no one can locate the true ones. Some turn into sects that destroy books or search their whole lives for the one volume that explains all the others.
