What do Nick's judgments reveal about his character in The Great Gatsby?
Nick's judgments reveal a number of things about his character.
In a functional sense, the fact that Nick's perspective is subjective and not objective. This is important for the reader's understanding of the narrative. The content of the novel is not objective fact but is intead observation.
Also, thematically, this is a story of instruction and Nick is the figure who learns lessons, both moral and practical. Nick's view of the world at the opening of the novel is not the same as it is in the end. This change is clear only in Nick's evolving judgments of the people around him.
In particular, Nick's respect for Gatsby's dedication to a single dream demonstrates the notion that Nick is able to avoid becoming a true cynic. He holds on to some hope, for himself and for others, that dreamers can suceed. This judgment of Gatsby is telling and is arguably the central moral lesson of the novel.
