Cormac McCarthy's quote suggests that in a harsh and challenging world, a person who is blind may have a deeper understanding or insight than those who can see. This perspective emphasizes the idea that true sight goes beyond physical vision; it includes emotional and psychological awareness. The blind man, in this context, symbolizes those who perceive reality in unique ways, possibly leading to wisdom derived from their experiences.

McCarthy highlights a profound theme in 'Outer Dark,' where darkness isn't just a lack of light but also represents ignorance, suffering, and the complexities of human existence. Thus, he implies that adversity can foster deeper insights, urging readers to consider the inner strength and clarity that can emerge from struggles. Ultimately, perception and understanding transcend physical abilities and can provide a richer view of the world.
