I have a low opinion of books; they are but piles of stones set up to show coming travelers where other minds have been, or at best signal smokes to call attention. No amount of word-making will ever make a single soul to know these mountains. As well seek to warm the naked and frostbitten by lectures on caloric and pictures of flame. One day's exposure to mountains is better than cartloads of books.
