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.

It seems a dreary waste of life to be analysing, indexing, extracting works and passages, in which one per cent of the contents are interesting, and not half of that per centage will ultimately appear in the flowing narrative.
