"Omelas" is a fictional city created by author Ursula K. Le Guin in her short story "The Ones Who Walk Away from Omelas." It is depicted as a utopian society filled with joy, celebration, and happiness, where the citizens experience a life of abundance and freedom. The city is known for its vibrant festivals and the overall well-being of its inhabitants. However, the prosperity of Omelas comes at a terrible cost. The happiness of the entire city relies on the suffering of a single child, who is kept in a dark, filthy room and subjected to neglect and abuse. This moral dilemma raises questions about the ethics of happiness and the sacrifices made for the greater good.
