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 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.
And of poetry, the success is not attained when it lulls and satisfies, but when it astonishes and fires us with new endeavours after the unattainable.
