...There will always be something in any poem, some reverberation of the numinous, which is not patient of explication, otherwise it would not be a poem.
But I must insist that I am not endorsing a lapse into some deliquescent, quasi-mystical vacuity. That would be an insupportable cop-out. The poet may ask of his reader the willing suspension of disbelief; he does not, ever, ask for any diminution of the critical faculties. On the contrary, he would have the reader's critical faculties raised to the highest possible degree. No one can be more aware of the fact that, if everything means everything, then nothing means anything. Purgatory would be for me a perpetual mooning about in some gormless Dream-Analysis Workshop. The poet attempts to work within the most stringent of strictures; he abhors above all else the slovenly, the imprecise, in thought or in language.
