From William Wordsworth's Preface to the 1802 edition of Lyrical Ballads :
[Footnote 1: It is worth while here to observe that the affecting parts of Chaucer are almost always expressed in language pure and universally intelligible even to this day.]
I cannot be insensible of the present outcry against the triviality and meanness both of thought and language, which some of my contemporaries have occasionally introduced into their metrical compositions; and I acknowledge that this defect where it exists, is more dishonorable to the Writer's own character than false refinement or arbitrary innovation, though I should contend at the same time that it is far less pernicious in the sum of its consequences. From such verses the Poems in these volumes will be found distinguished at least by one mark of difference, that each of them has a worthy purpose. Not that I mean to say, that I always began to write with a distinct purpose formally conceived; but I believe that my habits of meditation have so formed my feelings, as that my descriptions of such objects as strongly excite those feelings, will be found to carry along with them a purpose. If in this opinion I am mistaken I can have little right to the name of a Poet. For all good poetry is the spontaneous overflow of powerful feelings; but though this be true, Poems to which any value can be attached, were never produced on any variety of subjects but by a man who being possessed of more than usual organic sensibility had also thought long and deeply. For our continued influxes of feeling are modified and directed by our thoughts, which are indeed the representatives of all our past feelings; and as by contemplating the relation of these general representatives to each other, we discover what is really important to men, so by the repetition and continuance of this act feelings connected with important subjects will be nourished, till at length, if we be originally possessed of much organic sensibility, such habits of mind will be produced that by obeying blindly and mechanically the impulses of those habits we shall describe objects and utter sentiments of such a nature and in such connection with each other, that the understanding of the being to whom we address ourselves, if he be in a healthful state of association, must necessarily be in some degree enlightened, his taste exalted, and his affections ameliorated.
I have said that each of these poems has a purpose. I have also informed my Reader what this purpose will be found principally to be: namely to illustrate the manner in which our feelings and ideas are associated in a state of excitement. But speaking in less general language, it is to follow the fluxes and refluxes of the mind when agitated by the great and simple affections of our nature . . . .
Having dwelt thus long on the subjects and aim of these Poems, I shall request the Reader's permission to apprize him of a few circumstances relating to their style, in order, among other reasons, that I may not be censured for not having performed what I never attempted. The Reader will find that personifications of abstract ideas rarely occur in these volumes; and, I hope, are utterly rejected as an ordinary device to elevate the style, and raise it above prose. I have proposed to myself to imitate, and, as far as is possible, to adopt the very language of men; and assuredly such personifications do not make any natural or regular part of that language. They are, indeed, a figure of speech occasionally prompted by passion, and I have made use of them as such; but I have endeavoured utterly to reject them as a mechanical device of style, or as a family language which Writers in metre seem to lay claim to by prescription. I have wished to keep my Reader in the company of flesh and blood, persuaded that by so doing I shall interest him. I am, however, well aware that others who pursue a different track may interest him likewise; I do not interfere with their claim, I only wish to prefer a different claim of my own. There will also be found in these volumes little of what is usually called poetic diction; I have taken as much pains to avoid it as others ordinarily take to produce it; this I have done for the reason already alleged, to bring my language near to the language of men, and further, because the pleasure which I have proposed to myself to impart is of a kind very different from that which is supposed by many persons to be the proper object of poetry. I do not know how without being culpably particular I can give my Reader a more exact notion of the style in which I wished these poems to be written than by informing him that I have at all times endeavoured to look steadily at my subject, consequently, I hope that there is in these Poems little falsehood of description, and that my ideas are expressed in language fitted to their respective importance. Something I must have gained by this practice, as it is friendly to one property of all good poetry, namely, good sense; but it has necessarily cut me off from a large portion of phrases and figures of speech which from father to son have long been regarded as the common inheritance of Poets. I have also thought it expedient to restrict myself still further, having abstained from the use of many expressions, in themselves proper and beautiful, but which have been foolishly repeated by bad Poets, till such feelings of disgust are connected with them as it is scarcely possible by any art of association to overpower.
If in a Poem there should be found a series of lines, or even a single line, in which the language, though naturally arranged and according to the strict laws of metre, does not differ from that of prose, there is a numerous class of critics, who, when they stumble upon these prosaisms as they call them, imagine that they have made a notable discovery, and exult over the Poet as over a man ignorant of his own profession. Now these men would establish a canon of criticism which the Reader will conclude he must utterly reject, if he wishes to be pleased with these volumes. And it would be a most easy task to prove to him, that not only the language of a large portion of every good poem, even of the most elevated character, must necessarily, except with reference to the metre, in no respect differ from that of good prose, but likewise that some of the most interesting parts of the best poems will be found to be strictly the language of prose, when prose is well written. The truth of this assertion might be demonstrated by innumerable passages from almost all the poetical writings, even of Milton himself. I have not space for much quotation; but, to illustrate the subject in a general manner, I will here adduce a short composition of Gray, who was at the head of those who by their reasonings have attempted to widen the space of separation betwixt Prose and Metrical composition, and was more than any other man curiously elaborate in the structure of his own poetic diction.
