Response #2 Ursula K. Le Guin: The Ones Who Walk Away from Omelas

I think this story in many ways reflects the ideology that "ignorance is bliss." The community of the Omelas know that if they acknowledge the disadvantaged child that they will come to the realization that all is not right. Those who do come to this acknowledgment flee the city most likely due to their disgust and hatred of the ignorant city. In many ways this reflects our own humanity. Often when we are faced with the cold reality of children dieing due to hunger we either make the choice to help out or we turn our backs and think only of ourselves.
This is not to say that all people are ignorant, however, those who choose to live in a world where nothing is bad and everything is blissful are repressing the fact that everything is not blissful and there are many flaws and imperfections. Those who make this realization often find themselves unable to return to their old ways, so they flee from them, much the same way as the Omelas who fled. While it may not be literal in the sense that the people who come to this realization physically leave where they are, it may just be that they change their ideology and come closer to reality.
I feel that this story had a very valid moral lesson. That is, we should not ignore what is painful, and that we should do all that we can to fix what is wrong.
