Is there then, it will be asked, no essential difference between the language of prose and metrical composition? I answer that there neither is nor can be any essential difference. We are fond of tracing the resemblance between Poetry and Painting, and, accordingly, we call them Sisters: but where shall we find bonds of connection sufficiently strict to typify the affinity betwixt metrical and prose composition? They both speak by and to the same organs; the bodies in which both of them are clothed may be said to be of the same substance, their affections are kindred and almost identical, not necessarily differing even in degree; Poetry [2] sheds no tears "such as Angels weep," but natural and human tears; she can boast of no celestial Ichor that distinguishes her vital juices from those of prose; the same human blood circulates through the veins of them both.

[Footnote 2: I here use the word "Poetry" (though against my own judgment) as opposed to the word Prose, and synonomous with metrical composition. But much confusion has been introduced into criticism by this contradistinction of Poetry and Prose, instead of the more philosophical one of Poetry and Science. The only strict antithesis to Prose is Metre.]

If it be affirmed that rhyme and metrical arrangement of themselves constitute a distinction which overturns what I have been saying on the strict affinity of metrical language with that of prose, and paves the way for other distinctions which the mind voluntarily admits, I answer that the distinction of rhyme and metre is regular and uniform, and not, like that which is produced by what is usually called poetic diction, arbitrary and subject to infinite caprices upon which no calculation whatever can be made. In the one case the Reader is utterly at the mercy of the Poet respecting what imagery or diction he may choose to connect with the passion, whereas in the other the metre obeys certain laws, to which the Poet and Reader both willingly submit because they are certain, and because no interference is made by them with the passion but such as the concurring testimony of ages has shewn to heighten and improve the pleasure which co-exists with it. It will now be proper to answer an obvious question, namely, why, professing these opinions have I written in verse? To this in the first place I reply, because, however I may have restricted myself, there is still left open to me what confessedly constitutes the most valuable object of all writing whether in prose or verse, the great and universal passions of men, the most general and interesting of their occupations, and the entire world of nature, from which I am at liberty to supply myself with endless combinations of forms and imagery. Now, granting for a moment that whatever is interesting in these objects may be as vividly described in prose, why am I to be condemned if to such description I have endeavoured to superadd the charm which by the consent of all nations is acknowledged to exist in metrical language? To this it will be answered, that a very small part of the pleasure given by Poetry depends upon the metre, and that it is injudicious to write in metre unless it be accompanied with the other artificial distinctions of style with which metre is usually accompanied, and that by such deviation more will be lost from the shock which will be thereby given to the Reader's associations than will be counterbalanced by any pleasure which he can derive from the general power of numbers. In answer to those who thus contend for the necessity of accompanying metre with certain appropriate colours of style in order to the accomplishment of its appropriate end, and who also, in my opinion, greatly under-rate the power of metre in itself, it might perhaps be almost sufficient to observe that poems are extant, written upon more humble subjects, and in a more naked and simple style than what I have aimed at, which poems have continued to give pleasure from generation to generation. Now, if nakedness and simplicity be a defect, the fact here mentioned affords a strong presumption that poems somewhat less naked and simple are capable of affording pleasure at the present day; and all that I am now attempting is to justify myself for having written under the impression of this belief.

But I might point out various causes why, when the style is manly, and the subject of some importance, words metrically arranged will long continue to impart such a pleasure to mankind as he who is sensible of the extent of that pleasure will be desirous to impart. The end of Poetry is to produce excitement in coexistence with an overbalance of pleasure. Now, by the supposition, excitement is an unusual and irregular state of the mind; ideas and feelings do not in that state succeed each other in accustomed order. But if the words by which this excitement is produced are in themselves powerful, or the images and feelings have an undue proportion of pain connected with them, there is some danger that the excitement may be carried beyond its proper bounds. Now the co-presence of something regular, something to which the mind has been accustomed when in an unexcited or a less excited state, cannot but have great efficacy in tempering and restraining the passion by an intertexture of ordinary feeling. This may be illustrated by appealing to the Reader's own experience of the reluctance with which he comes to the re-perusal of the distressful parts of Clarissa Harlowe, or the Gamester. While Shakespeare's writings, in the most pathetic scenes, never act upon us as pathetic beyond the bounds of pleasure – an effect which is in a great degree to be ascribed to small, but continual and regular impulses of pleasurable surprise from the metrical arrangement. – On the other hand (what it must be allowed will much more frequently happen) if the Poet's words should be incommensurate with the passion, and inadequate to raise the Reader to a height of desirable excitement, then, (unless the Poet's choice of his metre has been grossly injudicious) in the feelings of pleasure which the Reader has been accustomed to connect with metre in general, and in the feeling, whether chearful or melancholy, which he has been accustomed to connect with that particular movement of metre, there will be found something which will greatly contribute to impart passion to the words, and to effect the complex end which the Poet proposes to himself.

If I had undertaken a systematic defence of the theory upon which these poems are written, it would have been my duty to develope the various causes upon which the pleasure received from metrical language depends. Among the chief of these causes is to be reckoned a principle which must be well known to those who have made any of the Arts the object of accurate reflection; I mean the pleasure which the mind derives from the perception of similitude in dissimilitude. This principle is the great spring of the activity of our minds and their chief feeder. From this principle the direction of the sexual appetite, and all the passions connected with it take their origin: It is the life of our ordinary conversation; and upon the accuracy with which similitude in dissimilitude, and dissimilitude in similitude are perceived, depend our taste and our moral feelings. It would not have been a useless employment to have applied this principle to the consideration of metre, and to have shewn that metre is hence enabled to afford much pleasure, and to have pointed out in what manner that pleasure is produced. But my limits will not permit me to enter upon this subject, and I must content myself with a general summary.

I have said that Poetry is the spontaneous overflow of powerful feelings: it takes its origin from emotion recollected in tranquillity: the emotion is contemplated till by a species of reaction the tranquillity gradually disappears, and an emotion, similar to that which was before the subject of contemplation, is gradually produced, and does itself actually exist in the mind. In this mood successful composition generally begins, and in a mood similar to this it is carried on; but the emotion, of whatever kind and in whatever degree, from various causes is qualified by various pleasures, so that in describing any passions whatsoever, which are voluntarily described, the mind will upon the whole be in a state of enjoyment. Now if Nature be thus cautious in preserving in a state of enjoyment a being thus employed, the Poet ought to profit by the lesson thus held forth to him, and ought especially to take care, that whatever passions he communicates to his Reader, those passions, if his Reader's mind be sound and vigorous, should always be accompanied with an overbalance of pleasure. Now the music of harmonious metrical language, the sense of difficulty overcome, and the blind association of pleasure which has been previously received from works of rhyme or metre of the same or similar construction, all these imperceptibly make up a complex feeling of delight, which is of the most important use in tempering the painful feeling which will always be found intermingled with powerful descriptions of the deeper passions. This effect is always produced in pathetic and impassioned poetry; while in lighter compositions the ease and gracefulness with which the Poet manages his numbers are themselves confessedly a principal source of the gratification of the Reader. I might perhaps include all which it is necessary to say upon this subject by affirming what few persons will deny, that of two descriptions either of passions, manners, or characters, each of them equally well executed, the one in prose and the other in verse, the verse will be read a hundred times where the prose is read once. We see that Pope by the power of verse alone, has contrived to render the plainest common sense interesting, and even frequently to invest it with the appearance of passion. In consequence of these convictions I related in metre the Tale of GOODY BLAKE and HARRY GILL, which is one of the rudest of this collection. I wished to draw attention to the truth that the power of the human imagination is sufficient to produce such changes even in our physical nature as might almost appear miraculous. The truth is an important one; the fact (for it is a fact) is a valuable illustration of it. And I have the satisfaction of knowing that it has been communicated to many hundreds of people who would never have heard of it, had it not been narrated as a Ballad, and in a more impressive metre than is usual in Ballads.

Having thus adverted to a few of the reasons why I have written in verse, and why I have chosen subjects from common life, and endeavoured to bring my language near to the real language of men, if I have been too minute in pleading my own cause, I have at the same time been treating a subject of general interest; and it is for this reason that I request the Reader's permission to add a few words with reference solely to these particular poems, and to some defects which will probably be found in them. I am sensible that my associations must have sometimes been particular instead of general, and that, consequently, giving to things a false importance, sometimes from diseased impulses I may have written upon unworthy subject; but I am less apprehensive on this account, than that my language may frequently have suffered from those arbitrary connections of feelings and ideas with particular words, from which no man can altogether protect himself. Hence I have no doubt that in some instances feelings even of the ludicrous may be given to my Readers by expressions which appeared to me tender and pathetic. Such faulty expressions, were I convinced they were faulty at present, and that they must necessarily continue to be so, I would willingly take all reasonable pains to correct. But it is dangerous to make these alterations on the simple authority of a few individuals, or even of certain classes of men; for where the understanding of an Author is not convinced, or his feelings altered, this cannot be done without great injury to himself: for his own feelings are his stay and support, and if he sets them aside in one instance, he may be induced to repeat this act till his mind loses all confidence in itself and becomes utterly debilitated. To this it may be added, that the Reader ought never to forget that he is himself exposed to the same errors as the Poet, and perhaps in a much greater degree: for there can be no presumption in saying that it is not probable he will be so well acquainted with the various stages of meaning through which words have passed, or with the fickleness or stability of the relations of particular ideas to each other; and above all, since he is so much less interested in the subject, he may decide lightly and carelessly.

Long as I have detained my Reader, I hope he will permit me to caution him against a mode of false criticism which has been applied to Poetry in which the language closely resembles that of life and nature. Such verses have been triumphed over in parodies of which Dr. Johnson's Stanza is a fair specimen.

 
  "I put my hat upon my head,
  And walk'd into the Strand,
  And there I met another man
  Whose hat was in his hand."
 

Immediately under these lines I will place one of the most justly admired stanzas of the "Babes in the Wood."

 
  "These pretty Babes with hand in hand
  Went wandering up and down;
  But never more they saw the Man
  Approaching from the Town."
 

In both of these stanzas the words, and the order of the words, in no respect differ from the most unimpassioned conversation. There are words in both, for example, "the Strand," and "the Town," connected with none but the most familiar ideas; yet the one stanza we admit as admirable, and the other as a fair example of the superlatively contemptible. Whence arises this difference? Not from the metre, not from the language, not from the order of the words; but the matter expressed in Dr. Johnson's stanza is contemptible. The proper method of treating trivial and simple verses to which Dr. Johnson's stanza would be a fair parallelism is not to say this is a bad kind of poetry, or this is not poetry, but this wants sense; it is neither interesting in itself, nor can lead to any thing interesting; the images neither originate in that sane state of feeling which arises out of thought, nor can excite thought or feeling in the Reader. This is the only sensible manner of dealing with such verses: Why trouble yourself about the species till you have previously decided upon the genus? Why take pains to prove that an Ape is not a Newton when it is self-evident that he is not a man.

I have one request to make of my Reader, which is, that in judging these Poems he would decide by his own feelings genuinely, and not by reflection upon what will probably be the judgment of others. How common is it to hear a person say, "I myself do not object to this style of composition or this or that expression, but to such and such classes of people it will appear mean or ludicrous." This mode of criticism so destructive of all sound unadulterated judgment is almost universal: I have therefore to request that the Reader would abide independently by his own feelings, and that if he finds himself affected he would not suffer such conjectures to interfere with his pleasure.

If an Author by any single composition has impressed us with respect for his talents, it is useful to consider this as affording a presumption, that, on other occasions where we have been displeased, he nevertheless may not have written ill or absurdly; and, further, to give him so much credit for this one composition as may induce us to review what has displeased us with more care than we should otherwise have bestowed upon it. This is not only an act of justice, but in our decisions upon poetry especially, may conduce in a high degree to the improvement of our own taste: for an accurate taste in Poetry and in all the other arts, as Sir Joshua Reynolds has observed, is an acquired talent, which can only be produced by thought and a long continued intercourse with the best models of composition. This is mentioned not with so ridiculous a purpose as to prevent the most inexperienced Reader from judging for himself, (I have already said that I wish him to judge for himself;) but merely to temper the rashness of decision, and to suggest that if Poetry be a subject on which much time has not been bestowed, the judgment may be erroneous, and that in many cases it necessarily will be so.

I know that nothing would have so effectually contributed to further the end which I have in view as to have shewn of what kind the pleasure is, and how the pleasure is produced which is confessedly produced by metrical composition essentially different from what I have here endeavoured to recommend; for the Reader will say that he has been pleased by such composition and what can I do more for him? The power of any art is limited and he will suspect that if I propose to furnish him with new friends it is only upon condition of his abandoning his old friends. Besides, as I have said, the Reader is himself conscious of the pleasure which he has received from such composition, composition to which he has peculiarly attached the endearing name of Poetry; and all men feel an habitual gratitude, and something of an honorable bigotry for the objects which have long continued to please them: we not only wish to be pleased, but to be pleased in that particular way in which we have been accustomed to be pleased. There is a host of arguments in these feelings; and I should be the less able to combat them successfully, as I am willing to allow, that, in order entirely to enjoy the Poetry which I am recommending, it would be necessary to give up much of what is ordinarily enjoyed. But would my limits have permitted me to point out how this pleasure is produced, I might have removed many obstacles, and assisted my Reader in perceiving that the powers of language are not so limited as he may suppose; and that it is possible that poetry may give other enjoyments, of a purer, more lasting, and more exquisite nature. But this part of my subject I have been obliged altogether to omit: as it has been less my present aim to prove that the interest excited by some other kinds of poetry is less vivid, and less worthy of the nobler powers of the mind, than to offer reasons for presuming, that, if the object which I have proposed to myself were adequately attained, a species of poetry would be produced, which is genuine poetry; in its nature well adapted to interest mankind permanently, and likewise important in the multiplicity and quality of its moral relations. From what has been said, and from a perusal of the Poems, the Reader will be able clearly to perceive the object which I have proposed to myself: he will determine how far I have attained this object; and, what is a much more important question, whether it be worth attaining; and upon the decision of these two questions will rest my claim to the approbation of the public.
