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.
Since every mortal power of Coleridge Was frozen at its marvellous source, The rapt one, of the godlike forehead, The heaven-eyed creature sleeps in earth: And Lamb, the frolic and the gentle, Has vanished from his lonely hearth.
Like an army defeated
The snow hath retreated,
And now doth fare ill
On the top of the bare hill;
The Ploughboy is whooping — anon — anon!
There's joy in the mountains:
There's life in the fountains;
Small clouds are sailing,
Blue sky prevailing;
The rain is over and gone.
A great poet ought to a certain degree to rectify men's feelings... to render their feelings more sane, pure and permanent, in short, more consonant to Nature.
