Premise: "The Ones Who Walk Away from Omelas" is a 1973 plotless, short, descriptive work of philosophical fiction, though popularly classified as a short story, by American writer Ursula K. Le Guin. With deliberately both vague and vivid descriptions, the narrator depicts a summer festival in the utopian city of Omelas, whose prosperity depends on the perpetual misery of a single child.
Hypothesis: Ursula K. Le Guin's work "The Ones Who Walk Away from Omelas" was published posthumously in 1973.
