Deception is a nearly universal trait in The Great Gatsby. While our narrator claims that he is "one of the few honest people" he has ever known, we come to doubt even his integrity. The claim that Gatsby is "great" is of course called into question, as Gatsby has fabricated his entire life to please a woman. This text seems to suggest that all human beings are inherently dishonest – as well as selfish, hypocritical, and destructive. The point is raised in the text that, while one may fool many men, no one can fool God – he is always watching.
In The Great Gatsby, Nick Carraway presents himself as the voice of reason and reliability, yet ultimately he proves to be an unreliable narrator.
Nick Carraway and Jay Gatsby are two sides of the same coin: each has built a successful façade to fool others, yet they can now no longer distinguish their true selves from the one they have created for the world.
Although characters throughout the book are consistently dishonest, their disappointment with the lies of others betrays the existence of a tangible, moral structure that guides the characters’ behavior.
