In "Lost in the Cosmos: The Last Self-Help Book," Walker Percy presents a thought-provoking idea that artists may possess heightened sensitivity to the world around them. This sensitivity could allow them to perceive underlying truths or dangers that others might overlook. Much like a canary in a mine, artists may instinctively sense shifts in societal moods or impending crises through their intuition and creativity.

This metaphor highlights the duality of the artist's experience; they can be seen as fragile yet deeply insightful. While their sensitivity might make them vulnerable to criticisms or emotions, it also equips them to tap into prophetic perceptions. By exploring this concept, Percy suggests that such artists play an essential role in illuminating the complexities of the human experience and warning society of potential threats.
