The Past is dead, and has no resurrection; but the Future is endowed with such a life, that it lives to us even in anticipation. The Past is, in many things, the foe of mankind; the Future is, in all things, our friend. In the Past is no hope; The Future is both hope and fruition. The Past is the text-book of tyrants; the Future is the Bible of the Free. Those who are solely governed by the Past stand like Lot's wife, crystallized in the act of looking backward, and forever incapable of looking before.
Herman MelvilleNearly all literature, in one sense, is made up of guide-books. Old ones tell us the ways our fathers went, through the thoroughfares and courts of old; but how few of those former places can their posterity trace, amid avenues of modern erections; to how few is the old guide-book now a clew! Every age makes its own guide-books, and the old ones are used for waste paper.
