Milan Kundera said this quote

In Tereza’s eyes, books were the emblems of a secret brotherhood. For she had but a single weapon against the world of crudity surrounding her: the novels. She had read any number of them, from Fielding to Thomas Mann. They not only offered the possibility of an imaginary escape from a life she found unsatisfying; they also had a meaning for her as physical objects: she loved to walk down the street with a book under her arm. It had the same significance for her as an elegant cane from the dandy a century ago. It differentiated her from others.
