The quote from Herman Melville's "Moby-Dick" highlights the inherent superiority and majesty of the mountain eagle, even when it appears to be in a low position. The eagle's flight within the confines of the gorge does not diminish its lofty status, as it remains above other birds that may soar in open spaces. This metaphor suggests that true greatness is often defined by one's potential and stature, regardless of current circumstances.

In a broader sense, the passage reflects themes of ambition and perseverance. It indicates that, like the mountain eagle, individuals can maintain their higher ideals and purpose even when faced with challenges. The imagery of the eagle flying within the mountains evokes a sense of resilience, suggesting that one's greatness can be sustained through trials and struggles, thus elevating them above others who might possess outward success.
