In Walker Percy's book, "Signposts in a Strange Land," he emphasizes the significance of cultural identity, asserting that a society's true greatness is reflected not by its economic achievements but by its artists and saints. These figures embody the values, creativity, and moral compass of a culture, showcasing its depth and richness beyond material wealth.

This perspective invites readers to reconsider how they measure success and progress. Instead of relying solely on gross national product (GNP) as a benchmark, Percy suggests looking to the contributions of those who inspire and uplift society, illustrating that a flourishing culture is one that nurtures creativity and spiritual integrity.
