If you do n’t talk about the books you read, they may, at best, only benefit you.  A book may serve as the subject of your inner dialogue until you forget its contents, but that inevitable outcome always approaches far too quickly.  In such case, our inner book is unlikely to reveal to us our own face while such mirroring may well occur in dialogue.  Therefore, when we not only think about books but assert and deny, we use books not as the means of reaffirming ourselves but as reference points for discourse.  After all, augmenting discourse is the raison d’etre for many a book’s creation and all books are a ‘speaking from’ whose voice is best found not in a sole utterance but as a mark within the discussion.
