In choosing words, it is to be remembered that there is not a really poor one in any language; each had originally some vivid meaning, but most of them have been worn smooth by passing from hand to hand, and hence the infinite care required in their use. "Language," says Max Müller, "is a dictionary of faded metaphors"; and every writer who creates a new image, or even reproduces an old one by passing it through a fresh mind, enlarges this vast treasure-house. And this applies not only to words of beauty, but to words of wit. "All wit," said Mr. Pitt, "is true reasoning "; and Rogers, who preserved this saying, added, that he himself had lived long before making the discovery that wit was truth. A final condition of literary art is _thoroughness_, which must be shown both in the preparation and in the revision of one's work. The most brilliant mind yet needs a large accumulated capital of facts and images, before it can safely enter on its business, Coleridge went to Davy's chemical lectures, he said, to get a new stock of metaphors. Addison, before beginning the Spectator, had accumulated three folio volumes of notes. "The greater part of an author's time," said Dr. Johnson, "is spent in reading in order to write; a man will turn over half a library to make one book." Unhappily, with these riches comes the chance of being crushed by them, of which the agreeable Roman Catholic writer, Digby, is a striking recent example. There is no satisfaction in being told, as Charles Lamb told Godwin, that "you have read more books that are not worth reading than any other man"; nor in being described, as was Southey by Shelley, as "a talking album, filled with long extracts from forgotten books on unimportant subjects." One must not have more knowledge than one can keep in subjection; but every literary man needs to accumulate a whole tool-chest in his memory, and another in his study, before he can be more than a journeyman at his trade.
