Nothing would, I know, have so effectually contributed to further the end which I have in view, as to have shown of what kind the pleasure is, and how that pleasure is produced, which is confessedly produced by metrical composition essentially different from that which I have here endeavoured to recommend:  for the Reader will say that he has been pleased by such composition; and what more can be done for him?  The power of any art is limited; and he will suspect, that, if it be proposed to furnish him with new friends, that can be 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 honourable 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 in these feelings enough to resist a host of arguments; 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, many obstacles might have been removed, and the Reader assisted in perceiving that the powers of language are not so limited as he may suppose; and that it is possible for Poetry to give other enjoyments, of a purer, more lasting, and more exquisite nature.  This part of the subject has not been altogether neglected, but it has not been so much 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, as to offer reasons for presuming, that if my purpose were fulfilled, 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 had in view:  he will determine how far it has been attained; 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.

(b) OF POETIC DICTION.

‘What is usually called Poetic Diction’ (Essay i. page 84, line 22).

Perhaps, as I have no right to expect that attentive perusal, without which, confined, as I have been, to the narrow limits of a Preface, my meaning cannot be thoroughly understood, I am anxious to give an exact notion of the sense in which the phrase poetic diction has been used; and for this purpose, a few words shall here be added, concerning the origin and characteristics of the phraseology, which I have condemned under that name.
