The quote reflects the complexity of understanding human behavior by comparing men to planets, suggesting that just as celestial bodies have both observable paths and hidden histories, people possess visible actions alongside a deeper, often concealed emotional and psychological backdrop. An astronomer can meticulously map the visible patterns of a planet's orbit, but a narrator must delve into the unseen thoughts and feelings that influence a person's actions, requiring a comprehensive approach to truly grasp their motivations.

Eliot emphasizes the importance of examining not only the overt actions of individuals but also the intense internal struggles that foster those actions. The mention of Prometheus highlights this idea, illustrating how profound suffering can amplify one's capacity for action, thereby challenging the norms of existence and defiance. By calling for a more nuanced understanding of humanity, the quote suggests that every action is deeply rooted in a complex web of emotions and experiences that deserve thoughtful exploration.
