The land is numb. It stands beneath the feet, and one may come Walking securely, till the sea extends Its limber margin, and precision ends. - Yvor Winters

What end impersonal, what breathless age, Incontinent of quiet and of years, What calm catastrophe will yet assuage
This final drouth of penitential tears?

Poetry, as nearly as I can understand it, is a statement in words about a human experience, whether the experience be real or hypothetical, major or minor; but it is a statement of a particular kind. Words are symbols for concepts, and the philosopher or scientist endeavors as far as may be to use them with reference to nothing save their conceptual content. Most words, however, connote feelings and perceptions, and the poet, like the writer of imaginative prose, endeavors to use them with reference not only to their denotations but to their connotations as well. Such writers endeavor to communicate not only concepts, arranged, presumably, either in rational order or in an order of apprehensible by the rational mind, but the feeling or emotion which the rational content ought properly to arouse.

We may say that a poem in the first place should offer us new perceptions, not only of the exterior universe, but of human experience as well; it should add, in other words, to what we have already seen. This is the elementary function for the reader. The corresponding function for the poet is a sharpening and training of his sensibilities; the very exigencies of the medium as he employs it in the act of perception should force him to the discovery of values which he never would have found without the convening of all the conditions of that particular act, conditions one or more of which will be the necessity of solving some particular difficulty such as the location of a rhyme or the perfection of a cadence with disturbance to the remainder of the poem.
