Cormac McCarthy's "Meridian of Blood" explores the interconnectedness of humanity through the lens of existence and experience. The quote emphasizes the notion that each individual is not isolated but rather part of an infinite continuum of being, where one's identity and understanding are shaped by relationships with others. This interconnected nature highlights the shared aspects of life and the influence people have on one another, creating a complex web of human experience.

The idea of "residing" in one another suggests that our perceptions and realities are intertwined, indicating a deep connection that transcends physical boundaries. In this infinite chain, each person's experiences and perspectives contribute to a broader understanding of existence. McCarthy's writing compels readers to consider the implications of this interdependence, urging them to reflect on their own places within the larger human narrative and the impact of their interactions on others.
