In "Lancelot" by Walker Percy, the protagonist grapples with the impact of discovering the truth about Margot. This revelation raises deeper questions about the nature of truth and the necessity of knowing more beyond the initial discovery. The character reflects on why such certainty about Margot's situation feels inadequate and why it drives a desire for further proof and understanding.

This quest for knowledge appears to create a barrier to action, prompting the character to wonder if the pursuit of truth can lead to inaction. The narrative explores the complex relationship between knowledge, certainty, and the decisions that follow, suggesting that sometimes, the more one knows, the more hesitant they may become to act on that knowledge.
