"[T]ake at hazard any three pages of the Essays or History; and, glimmering below the stream of the narrative, as it were, you, an average reader, see one, two, three, a half score of allusions to other historic facts, characters, literature, poetry, with which you are acquainted. Why is this epithet used? Whence is that simile drawn? How does he manage, in two or three words, to paint an individual, or to indicate a landscape? Your neighbour, who has his reading, and his little stock of literature stowed away in his mind, shall detect more points, allusions, happy touches, indicating not only the prodigious memory and vast learning of this master, but the wonderful industry, the honest, humble previous toil of this great scholar. He reads twenty books to write a sentence; he travels a hundred miles to make a line of description."
