A.S. Byatt's novel, "The Children's Book," presents the idea that memories play a crucial role in shaping our identity, much like the foundational structure of our bones. By drawing parallels between memories and physical anatomy, the author emphasizes that these memories are vital to our personal development and the essence of who we are. They influence our thoughts, actions, and relationships, reinforcing their importance in our lives.

The mention of memories as "essential and structural" suggests that they are not merely fleeting recollections but rather foundational elements that support our experiences and growth. Just as bones provide a framework for our bodies, memories create a framework for our understanding of the world, guiding us through the complexities of life and informing our decisions and emotions.
