In Vladimir Nabokov's book "Pnin," the exploration of nostalgia reveals how holding onto childhood memories can become a heavy burden. The character grapples with the weight of preserving fragments of his past, suggesting that some experiences are too tangible and complex to maintain without feeling overwhelmed.

Additionally, the narrative reminds readers that faith does not initially stem from physical sensations. This reflection on the connection between memory and perception highlights the difference between emotional attachment and the essence of belief, emphasizing how intricate and sometimes challenging it is to reconcile these feelings.
