In "Lancelot," Walker Percy explores profound themes through the lens of self-discovery and existential inquiry. The protagonist grapples with the complexity of existence and his search for understanding in a world filled with chaos. The narrative suggests that the quest for meaning can sometimes seem daunting, as vast as solving the mysteries of the universe itself.

However, Percy implies that navigating the challenges of everyday life can be even more difficult than tackling grand philosophical issues. This reflects a commentary on the human condition, emphasizing that the struggles we face in our daily lives often eclipse the abstract pursuits of knowledge and understanding in their complexity and impact. Ultimately, the story advocates for finding significance in the seemingly mundane aspects of existence.
