What this quote means

Julien Gracq uses the mirror metaphor to express that reading reveals the reader as much as the book. A book has no fixed meaning; it reflects what the reader brings. If a coarse person reads it, they'll only take coarseness from it. This resonates because it highlights the subjectivity of reading and makes us responsible: we are actors in our understanding. It applies when we're disappointed by a book others loved, or vice versa.

How to apply it daily

Before judging a book, ask yourself what you projected onto it. Re-read a passage you disliked, seeking a different perspective.
