In "The Goldfinch," author Donna Tartt explores the theme of identity and self-deception through the quote by François de La Rochefoucauld. The quote suggests that our tendency to present false versions of ourselves to others may ultimately lead to a loss of self-awareness. We often wear masks in social situations, crafting personas to fit in or to be accepted, which can obscure our true selves over time.

This idea resonates throughout the novel as characters struggle with their identities in a complex world. As they navigate relationships and societal expectations, they risk becoming disconnected from who they truly are. Tartt highlights the consequences of this disconnection, illustrating the profound impact of external perceptions on personal identity and the journey towards self-discovery.
