The Left Hand of Darkness by Ursula K. Le Guin
Prophecy on Gethen.
One aspect of folktales are prophecies spoken by human or animal oracles. Prophecies have the mixed message that events are predetermined but the conclusion still relies on the choices characters make to fulfil the prophecy. In Le Guin's novel The Left Hand of Darkness, the Foretellers are a specialized community of various Gethen, sane, insane, in kemmer, celibates and perverts, who for a price will answer any question you put to them but buyer beware, how you word the question affects the answer.
In Chapter 4: The Nineteenth Day, we read the cautionary story of Lord Berosty and his very expensive yet poorly worded question to The Foretellers, “On what day shall I die?” They give him an answer “The nineteenth.” but no month or year. He is so unhappy with the answer, he shuts himself up in a tower. His kemmering initially offers his life for the answer to “How long will Ashe Berosty rem ir Ipe live?” But the Foretellers freely answer: “Longer than Herbor of Geganner!” When the Lord is not consoled by the second answer given, he kills his kemmering and goes insane. The Lord then commits suicide a month later on a nineteenth day of the month of Thern, a winter month.
In Chapter 5: The Domestication of Hunch, Genly Ai visits the famous Fortellers at Otherhord. He is given advice so his question does not frustrate the Fortellers with an unanswerable question. Genly goes with a simple “yes” or “no” answer and asks: “Will this world Gethen be a member of the Ekumen of Known World, five years from now?” The answer is yes. But this answer does not come with a method, a date, a location, or even if he is the successful Envoy, it simply states the Gethen will join the Ekumen. So on one the hand there is some determinism but there is still room for active freewill.
