Throughout The Giver, Lowry attempts to awaken each and every reader to the dangers that exist when people opt for conformity over individuality and for unexamined security over freedom. At one time in the past, the people who inhabited Jonas' community intended to create a perfect society. They thought that by protecting the citizens from making wrong choices (by having no choices), the community would be safe. But the utopian ideals went awry, and people became controlled and manipulated through social conditioning and language. Now, even the expression "love" is an empty ideal. For example, when Jonas asks his parents if they love him, his mother scolds him for using imprecise language. She says that "love" is "a very generalized word, so meaningless that it's become almost obsolete." To Jonas, however, love is a very real feeling.
