The protagonist observes the bustling square from the solitude of an empty café, reflecting on the nature of life's truths. His insight reveals a deep belief that if young people were made fully aware of these harsh realities right from the start, they might find it too daunting to embark on their journeys. This suggests that ignorance can sometimes be a protective shield, allowing individuals to pursue their dreams without the burden of inevitable struggles weighing them down.

This contemplation underscores a broader theme within Cormac McCarthy's "All the Pretty Horses." It highlights the tension between youthful optimism and the sobering realities of life. By arguing that limited awareness of life's truths is beneficial for the young, the author invites readers to consider how naivety can provide the courage necessary to face the unknown, ultimately emphasizing the importance of hope and perseverance in the pursuit of one's aspirations.
