The theme of "The Giver" by Lois Lowry is the significance of memory to human life. The novel explores how memories shape our experiences and emotions, and how they contribute to our individuality and identity. The community in the novel has eliminated all pain from their lives by giving up the memories of their societys collective experiences. However, this has also resulted in a loss of individuality and freedom, as well as a devaluation of the value of the individual. The novel encourages readers to celebrate differences instead of pretending they do not exist, and to question everything about their lives instead of blindly following rules. Other themes in the novel include the importance of choices, the value of remembering the past, and the negative consequences of a society that values conformity over individuality.
