The tragic element in poetry is like Saturn in alchemy, the Malevolent, the Destroyer of Nature ; but without it no true Aurum Potabile, or Elixir of Life, can be made.
I take as metaphysical poetry that in which what is ordinarily apprehensible only by thought is brought within the grasp of feeling, or that in which what is ordinarily only felt is transformed into thought without ceasing to be 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, kindred to that which was before the subject of contemplation, is gradually produced, and does itself actually exist in the mind.
It is a curious thing how poets tend to become ascetics.... Even a debauch for them is a self-flagellation. They go on the loose in cruelty against themselves, admitting that they are pandering to, and despising, the lower self.
I should tell you that honestly, on my honour of a Nearwicked, I always think in a wordworth's of that primed favourite continental poet, Daunty, Gouty and Shopkeeper, A.G., whom the generality admoyers in this that is and that this is to come.
