In "Lectures on Literature," Vladimir Nabokov suggests that a true connoisseur of literature engages with profound works not merely through emotional or intellectual faculties but on a deeper, instinctive level. He emphasizes that the spine symbolizes this unique connection, as it captures the physical response of thrill or tension that accompanies the experience of reading great literature. This notion indicates that an element of physicality enhances our understanding and appreciation of complex texts.

Nabokov also points out the necessity of maintaining a degree of detachment while delving into literature. This balance helps readers absorb the essence of a story while retaining their critical faculties. By advocating for this dual approach—responsive yet discerning—Nabokov invites readers to explore the transformative power of literature, suggesting that it stirs our very being through a combination of emotional and analytical engagement.
