In the second place, Wordsworth is the most consistent of all the great English poets of democracy, though here as elsewhere his interest is mainly not in the external but in the spiritual aspect of things. From his insistence that the meaning of the world for man lies not in the external events but in the development of character results his central doctrine of the simple life. Real character, he holds, the chief proper object of man's effort, is formed by quietly living, as did he and the dalesmen around him, in contact with Nature and communion with God rather than by participation in the feverish and sensational struggles of the great world. Simple country people, therefore, are nearer to the ideal than are most persons who fill a larger place in the activities of the world. This doctrine expresses itself in a striking though one-sided fashion in his famous theory of poetry--its proper subjects, characters, and diction. He stated his theory definitely and at length in a preface to the second edition of 'Lyrical Ballads,' published in 1800, a discussion which includes incidentally some of the finest general critical interpretation ever made of the nature and meaning of poetry. Wordsworth declared: 1. Since the purpose of poetry is to present the essential emotions of men, persons in humble and rustic life are generally the fittest subjects for treatment in it, because their natures and manners are simple and more genuine than those of other men, and are kept so by constant contact with the beauty and serenity of Nature. 2. Not only should artificial poetic diction (like that of the eighteenth century) be rejected, but the language of poetry should be a selection from that of ordinary people in real life, only purified of its vulgarities and heightened so as to appeal to the imagination. (In this last modification lies the justification of rime.) There neither is nor can be any _essential_ difference between the language of prose and that of poetry.
This theory, founded on Wordsworth's disgust at eighteenth century poetic artificiality, contains a very important but greatly exaggerated element of truth. That the experiences of simple and common people, including children, may adequately illustrate the main spiritual aspects of life Wordsworth unquestionably demonstrated in such poems as 'The Reverie of Poor Susan,' 'Lucy Gray,' and 'Michael.' But to restrict poetry largely to such characters and subjects would be to eliminate not only most of the external interest of life, which certainly is often necessary in giving legitimate body to the spiritual meanings, but also a great range of significant experiences which by the nature of things can never come to lowly and simple persons. That the characters of simple country people are on the average inevitably finer and more genuine than those of others is a romantic theory rather than a fact, as Wordsworth would have discovered if his meditative nature had, allowed him to get into really direct and personal contact with the peasants about him. As to the proper language of poetry, no one to-day (thanks partly to Wordsworth) defends artificiality, but most of Wordsworth's own best work, as well as that of all other poets, proves clearly that there _is_ an essential difference between the language of prose and that of poetry, that much of the meaning of poetry results from the use of unusual, suggestive, words and picturesque expressions, which create the essential poetic atmosphere and stir the imagination in ways distinctly different from those of prose. Wordsworth's obstinate adherence to his theory in its full extent, indeed, produced such trivial and absurd results as 'Goody Blake and Harry Gill,' 'The Idiot Boy,' and 'Peter Bell,' and great masses of hopeless prosiness in his long blank-verse narratives.
