If this opinion be erroneous, I can have little right to the name of a Poet.

For all good poetry is the spontaneous overflow of powerful feelings: and 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, our feelings will be connected with important subjects, till at length, if we be originally possessed of much 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 connexion with each other, that the understanding of the Reader must necessarily be in some degree enlightened, and his affections strengthened and purified.
It has been said that each of these poems has a purpose.

Another circumstance must be mentioned 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.
A sense of false modesty shall not prevent me from asserting, that the Reader's attention is pointed to this mark of distinction, far less for the sake of these particular Poems than from the general importance of the subject.

The subject is indeed important! For the human mind is capable of being excited without the application of gross and violent stimulants; and he must have a very faint perception of its beauty and dignity who does not know this, and who does not further know, that one being is elevated above another, in proportion as he possesses this capability.
