In [Ursula K. Le Guin’s “Ones Who Walk Away From Omelas“], a few people reject the terms of [their city’s prosperity being built on the suffering of a single child], and this is where I have mixed feelings about it: they quietly leave the city, alone, to go somewhere else, somewhere they can’t even imagine. They are “the ones who walk away from Omelas,” after all. They are the ones who will not accept bliss if it’s founded on another’s pain.
But I don’t know; it doesn’t seem enough. The story seems to accept that there is an act that cannot be committed: that protest and tattling are not an option, that no one ever sees that there is justice in bringing the oppressed to light and doing something. Or even questioning whether a child’s sacrifice is at all causal in bringing about their happiness. It’s a thoughtful story, but it need a sequel, “The Ones Who Storm the Gates of Omelas.”
