"Judging a poem is like judging a pudding or a machine. One demands that it work. It is only because an artifact works that we infer the intention of an artificer. 'A poem should not mean but be.' A poem can be only through its meaning – since its medium is words – yet it is, simply is, in the sense that we have no excuse for inquiring what part is intended or meant. Poetry is a feat of style by which a complex of meaning is handled all at once. Poetry succeeds because all or most of what is said or implied is relevant; what is irrelevant has been excluded, like lumps from pudding and 'bugs' from machinery."
