The quote by Philip K. Dick from "The Man in the High Castle" emphasizes the idea that best-selling books are not necessarily of high quality. The popularity of a book, indicated by its status as a best seller, can often be misleading. Many works that achieve this status might lack depth or value, reinforcing the notion that sales alone are not a reliable measure of a book's merit.

This perspective invites readers to critically analyze literature beyond commercial success. It suggests that judgment should not solely rely on popularity but rather on the substance and artistry of the work itself. Ultimately, true literary worth is found in the richness of ideas and creativity rather than the number of copies sold.
