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 books she took out of the municipal library. . . . 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 for the dandy a century ago. It differentiated her from others.
(Comparing the book to the elegant cane of the dandy is not absolutely precise. A dandy’s cane did more than make him different; it made him modern and up to date. The book made Tereza different, but old-fashioned. Of course, she was too young to see how old-fashioned she looked to others. The young men walking by with transistor radios pressed to their ears seemed silly to her. It never occurred to her that they were modern.)
The specific objects may change but the effect remains the same. Replace “transistor radio” with “iPhone” or similar. The Unbearable Lightness of Being was first published in English in 1984. I think some version of the clerisy will always exist, and, fortunately, membership is not restricted to the degreed; it is open to anyone who wishes to read and think.
