Vladimir Nabokov's quote from "Lolita" suggests that approaching a work of fiction solely for factual knowledge about a nation, social class, or its creator is a naive endeavor. He implies that literature should transcend mere informational purpose and should be appreciated for its artistry, complexity, and emotional depth. Fiction, in Nabokov's view, is not a straightforward source of data but rather a nuanced exploration of human experience.

By calling this approach childish, Nabokov emphasizes that readers ought to engage with literature on a deeper level. There is a rich world within fictional narratives that goes beyond surface-level details. This perspective encourages readers to immerse themselves in the imaginative aspects of storytelling, opening themselves to the profound insights that fiction can provide, rather than viewing it as a mere reflection of reality.
