Community function as a cohesive unit. When Jonas turns twelve, the Community selects him to be the new "Receiver of Memories." Only the "Giver" knows the truth and memories of the past, and now he must pass these memories on to Jonas. Lowry subtly creates an uneasy feeling that something is wrong with this "perfect world."
The Community's advisors intend to establish security within utopian society, but they really establish a stifling dystopia. To protect people from the risks of making poor or wrong decisions in life, the advisors plan and dictate the lives of the people. In effect, the citizens have no freedom of choice; they do not choose their job or even their spouse. Moreover, the advisors inhibit the people's ability to feel because they want to spare them from the hardships and pain of life. For instance, individuals must take a pill everyday, which suppresses passionate feelings. The citizens do not know or experience true emotions like love. One of the goals of the Community is to achieve "sameness" so that no one feels embarrassed or excluded for being different. However, this limits individuality and freedom of expression because everyone conforms to a certain desired image. Finally, to relieve the population of the horrors and devastation of the world and the past, the advisors isolate the Community from the rest of the world and give the burden of holding the memories of the past to a single member of society: the "Receiver." Therefore, the Community lives only in the present, and the people have a narrow perspective of life because they only know their community and way of life. They are naive; they do not gain knowledge or wisdom from the memories.
While receiving the memories, Jonas learns a different and better way to live and realizes what he and the Community have been missing. He decides that something must be done to change the current conditions and enlighten his community. He decides to leave the Community with a newborn, Gabriel, who had been chosen for release because he has trouble sleeping. By escaping the community, all of the memories that Jonas has received from The Giver will be transmitted back to the citizens in the Community, forcing them to experience feelings and emotions and to remember their past. Jonas travels for days and days with Gabriel, who is dying from starvation and the cold weather. Finally, they come to the top of a hill where there is snow and a sled. They get on the sled and ride downhill toward music and Christmas lights. In Plato's Allegory of the Cave, prisoners sit in a cave, chained down, watching images cast on the wall in front of them. They accept these views as reality and they are unable to grasp their overall situation: the cave and images are a ruse, a mere shadow show orchestrated for them by unseen men. At some point, a prisoner is freed and is forced to see the situation inside the cave. Initially, one does not want to give up the security of his or her familiar reality; the person is dragged past the fire and up the entranceway. This is a difficult and painful struggle. When individuals step into the sunshine, their eyes slowly accommodate to the light and their fundamental view of the world, of reality, is transformed. They come to see a deeper, more genuine, authentic reality: a reality marked by reason. The individual then makes the painful readjustment back into the darkness of the cave to free the prisoners. However, because he now seems mad, describing a new strange reality, they reject him to the point of threatening to kill him. Jonas's assignment to become the new "Receiver" is how he was dragged out into the sun light.
He understands that the only way for him to teach his fellow prisoners the truth is to force them to see as well. The Philosopher-King as described by Plato should be intelligent, ambition in things of the mind, diligent, disciplined, temperate, and reliable. Only citizens who posses all of these required qualities should be considered candidates for a philosopher-ruler. Jonas knows the enlightenment of the Community will be difficult and painful. The "Giver" remains with the Community in order to help them through the challenging times ahead. This is the best thing Jonas and the Giver could do for them. They realize it will be a lot of work to lead the other citizens into the light of knowledge but the business of rulers is not to make themselves happy. Their happiness is to be realized in the happiness of citizens in the ideal state and the people of the Community do not have enough knowledge to know
happiness. Jonas's decision to leave his community is morally justified because in this instance the obligations of the leader and the obligations to knowledge coincide. The "Giver" also makes the moral decision to stay behind even though he would prefer to accompany Jonas. Jonas also has a moral obligation to Gabriel who is incapable of protecting himself. Right before the final sled ride to Elsewhere, Jonas realizes he is no longer concerned with himself. His only concern is he may not be able to save Gabriel.
