The nature of the final poetic order is the outcome of a dialectical struggle between the recollected occasions of feeling and the verbal system. As a society the verbal system is actively coercive upon the occasions it is attempting to embody; what it cannot embody truthfully it excludes. As a potential community the occasions are passively resistant to all claims of the system to embody them which they do not recognize as just; they decline all unjust persuasions. As members of crowds, every occasion competes with every other, demanding inclusion and a dominant position to which they are not necessarily entitled, and every word demands that the system shall modify itself in its case, that a special exception shall be made for it and it only.
In a successful poem, society and community are one order and the system may love itself because the feelings which it embodies are all members of the same community, loving each other and it. A poem may fail in two ways; it may exclude too much (banality), or attempt to embody more than one community at once (disorder).
In writing a poem, the poet can work in two ways. Starting from an intuitive idea of die kind of community he desires to call into being, he may work backwards in search of the system which will most justly incarnate that idea, or, starting with a certain system, he may work forward in search of the community which it is capable of incarnating most truthfully. In practice he nearly always works simultaneously in both directions, modifying his conception of the ultimate nature of the community at the immediate suggestions of the system, and modifying the system in response to his growing intuition of the future needs of the community.
A system cannot be selected completely arbitrarily nor can one say that any given system is absolutely necessary. The poet searches for one which imposes just obligations on the feelings. "Ought" always implies "can" so that a system whose claims cannot be met must be scrapped. But the poet has to beware of accusing the system of injustice when what is at fault is the laxness and self-love of the feelings upon which it is making its demands.
Every poet, consciously or unconsciously, holds the following absolute presuppositions, as the dogmas of his art:
i) A historical world exists, a world of unique events and unique persons, related by analogy, not identity. The number of events and analogical relations is potentially infinite. The existence of such a world is a good, and every addition to the number of events, persons and relations is an additional good.
The historical world is a fallen world, i.e., though it is good that it exists, the way in which it exists is evil, being full of unfreedom and disorder.
The historical world is a redeemable world. The unfreedom and disorder of the past can be reconciled in the future.
It follows from the first presupposition that the poet's activity in creating a poem is analogous to Gods activity in creating man after his own image. It is not an imitation, for were it so, the poet would be able to create like God
It is untrue, strictly speaking, to say that a poet should not write poems unless he must; strictly speaking it can only be said that he should not write them unless he can. The phrase is sound in practice, because only in those who can and when they can is the motive genuinely compulsive.
In those who profess a desire to write poetry, yet exhibit an incapacity to do so, it is often the case that their desire is not for creation but for self-perpetuation, that they refuse to accept their own mortality, just as there are parents who desire children, not as new persons analogous to themselves, but to prolong their own existence in time. The sterility of this substitution of identity for analogy is expressed in the myth of Narcissus. When the poet speaks, as he sometimes does, of achieving immortality through his poem, he does not mean that he hopes, like Faust, to live for ever, but that he hopes to rise from the dead. In poetry as in other matters the law holds good that he who would save his life must lose it; unless the poet sacrifices his feelings completely to the poem so that they are no longer his but the poem's, he fails.
