The Lois Lowry novel The Giver is set in a futuristic, Utopian society. The things that make society less than perfect have been eliminated. Everyone looks similar and is manipulated to act similar. The matter of choice has been taken away so the competitiveness that sometimes leads to ugliness is a moot point. The nature vs. nurture debate has also been eliminated as children are taken from “birth mothers” and raised in a nurturing center for the first year of their lives. When people become too old to contribute to the society, they are released (to death). All of these elements are meant to ensure the continuance of this “Utopian” setting.
