Several of my Friends are anxious for the success of these Poems from a belief, that if the views, with which they were composed, were indeed realized, a class of Poetry would be produced, well adapted to interest mankind permanently, and not unimportant in the multiplicity and in the quality of its moral relations […].
The principal object then which I proposed to myself in these Poems was to make the incidents of common life interesting by tracing in them, truly though not ostentatiously, the primary laws of our nature: chiefly as far as regards the manner in which we associate ideas in a state of excitement.
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.
[…] it is proper that I should mention one other circumstance which distinguishes these Poems from the popular Poetry of the day; it is this, that the feeling therein developed gives importance to the action and situation and not the action and situation to the feeling.
For a multitude of causes unknown to former times are now acting with a combined force to blunt the discriminating powers of the mind, and unfitting it for all voluntary exertion to reduce it to a state of almost savage torpor.
Except in a very few instances the Reader will find no personifications of abstract ideas in these volumes, not that I mean to censure such personifications: they may be well fitted for certain sorts of composition, but in these Poems I propose to myself to imitate, and, as far as possible, to adopt the very language of men, and I do not find that such personifications make any regular or natural part of that language. I wish to keep my Reader in the company of flesh and blood, persuaded that by so doing I shall interest him.
Poetry 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.
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.
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.
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.
