The quote reflects on the nature of the books within a particular bookshelf, emphasizing that each book offers a unique experience that remains isolated and ultimately unproductive. Reading these books does not lead to any profound understanding or achievement; instead, it serves merely as a means to pass the time. The act of reading is likened to enjoying a lengthy conversation with an insightful friend, where no goal is reached, but the journey itself is enjoyable.

This perspective presents literature as something that can enrich our lives in a transient way. The books may lack direct utility or purpose, yet they provide a valuable opportunity for exploration and reflection. Lethem suggests that this seemingly aimless engagement is still worthwhile, as it allows for a deeper appreciation of knowledge and creativity, even if it does not contribute to tangible outcomes.
