Jorges Luis Borges

"Fauna of Mirrors" where we learn that the people of Canton believed another hostile world was behind every reflective surface, the people of whom are enslaved into copying our actions for now, but whose turn to rise will come, and whose uprising will be heralded by.... a rogue yellow fish you may see in the mirror that shouldn't be there. That such a potentially risible, laughable notion instead haunts the memory is further testimony to Borges' mastery.
