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
