In the exposition of The Great Gatsby, Nick introduces himself as narrator and remarks that Gatsby at one time "represented everything for which I have an unaffected scorn." However, now in retrospect, Nick perceives Gatsby as having had
...a romantic readiness such as I have never found in any other person and which it is not likely I shall ever find again.
It is this "romantic readiness," this grand conception of himself, that makes Gatsby come alive to Nick, "delivered suddenly from the womb of his purposeless splendor." It is the pure belief of Jay Gatsby that he can, indeed, repeat the past, that he has the power to spring "from his Platonic conception of himself." Further, it is belief in love, his conviction the pursuit of a grail, his extraordinary gift of hope, his loyalty and chivalrous protection of Daisy are what bring Nick to call to Gatsby, "They're a rotten crowd....You're worth the whole damn bunch together."
While Gatsby remains a bootlegger and a fraud of sorts, Nick comes to admire Gatsby for his sincerity in love, loyalty, and friendship It is the Buchanans who are the careless people who value no one.
