In "Lost in the Cosmos: The Last Self-Help Book," Walker Percy explores the philosophical implications of Darwin's theory of evolution through a dialogue involving Wallace. Wallace questions the practicality of evolution by pointing out the presence of advanced brains in beings that do not need them for survival, suggesting a disconnect between intelligence and evolutionary necessity. This leads to a contemplation of the purpose of human intellect beyond mere survival.
Percy uses this inquiry to delve into the existential concerns that arise from the evolution of consciousness. The quote highlights a fundamental question about whether advanced cognitive abilities, exemplified by figures like Einstein and Beethoven, serve a clear evolutionary function or if they point to a deeper, perhaps spiritual, aspect of human existence. This reflection invites readers to consider the complex relationship between intellect, purpose, and the mysteries of human life.
