The reason why so few good books are written is, that so few people that can write know anything. In general an author has always lived in a room, has read books, has cultivated science, is acquainted with the style and sentiments of the best authors, but he is out of the way of employing his own eyes and ears. He has nothing to hear and nothing to see. His life is a vacuum.
