In Rick Riordan's "The Serpent's Shadow," the concept of knowledge is portrayed as something that cannot simply be handed over to someone; instead, it requires an individual’s active pursuit and effort to attain. This theme underscores the idea that true understanding and wisdom come from personal experiences and challenges faced throughout one's journey.

The message emphasizes the importance of personal growth through seeking knowledge. It suggests that the path to learning is filled with obstacles that must be navigated, reinforcing the belief that significant insight is built through dedication, struggle, and finding answers independently.
