In Vladimir Nabokov's novel "Pnin," the protagonist, Pnin, finds himself in a series of comical yet tragic situations, emphasizing his sense of displacement and confusion in a new environment. The quote highlights Pnin's perpetual struggles and mistakes, showcasing how they reflect his deeper issues with identity and belonging. Despite any external appearances or circumstances, his misfortunes reveal the dissonance he experiences in navigating life in America.

The phrase "All of which does not alter the fact that Pnin was on the wrong train" serves as a metaphor for Pnin's ongoing existential challenges. It suggests that no matter the reasoning or context, Pnin’s fundamental predicament remains: he is fundamentally lost. This highlights how our personal journeys can be marred by errors and misdirections, yet these experiences shape who we are and how we perceive our place in the world.
