Answer:
In the book "The Giver" by Lois Lowry, the Receiver of Memory is given access to all the painful and joyful memories of the past. The painful memories that the Receiver experiences help him gain wisdom because they allow him to understand the true nature of the world, including its suffering and injustice. By experiencing memories of war, famine, and other forms of suffering, the Receiver is able to develop empathy and compassion, and gain a deeper understanding of the importance of human emotions and connections. This allows the Receiver to help guide the community towards a more just and equitable society, based on the lessons he has learned from the memories. Overall, the Receiver's access to painful memories is a crucial element in his growth and development as a wise and compassionate leader.
