In Cormac McCarthy's novel "The Crossing," the theme of identity and perception is explored through the metaphor of masks. The idea that a mask represents the true self suggests that what we show the world often conceals deeper realities. This reflects the complexities of human nature and our interactions, emphasizing how societal roles and expectations influence our behavior and self-presentation.

The quote, "In this world the mask is what is true," suggests a profound commentary on authenticity and existence. It raises questions about what lies beneath our facades and challenges readers to consider the validity of their perceptions. McCarthy's work often delves into the dualities of life, prompting us to reflect on the masks we wear and the truths we hide behind them.
