Either still I find Some imperfection in the chosen theme, Or see of absolute accomplishment Much wanting, so much wanting, in myself, That I recoil and droop, and seek repose In listlessness from vain perplexity, Unprofitably travelling towards the grave.
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, kindred to that which was before the subject of contemplation, is gradually produced, and does itself actually exist in the mind.
It may be safely affirmed that there neither is, nor can be, any essential difference between the language of prose and metrical 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 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.
Those obstinate questionings Of sense and outward things,
Fallings from us, vanishings;
Blank misgivings of a Creature
Moving about in worlds not realised,
High instincts before which our mortal Nature
Did tremble like a guilty thing surprised
