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

Metal, intrinsic value, deep and dense,
Preanimate, inimitable, still,
Real, but an evil with no human sense,
Dispersed the mind to concentrate the will.

Now verse is more valuable than prose … for the simple reasons that its rhythms are faster and more highly organized than are those of prose, and so lend themselves to a greater complexity and compression of relationship, and that the intensity of this convention renders possible a greater intensity of other desirable conventions, such as poetic language and devices of rhetoric.

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.
