Nevertheless, the function of poetry, like that of science, can only be fulfilled by the conception of harmonies that become clearer as they grow richer. As the chance note that comes to be supported by a melody becomes in that melody determinate and necessary, and as the melody, when woven into a harmony, is explicated in that harmony and fixed beyond recall; so the single emotion, the fortuitous dream, launched by the poet into the world of recognizable and immortal forms, looks in that world for its ideal supports and affinities. It must find them or else be blown back among the ghosts. The highest ideality is the comprehension of the real. Poetry is not at its best when it depicts a further possible experience, but when it initiates us, by feigning something which as an experience is impossible, into the meaning of the experience which we have actually had.
The highest example of this kind of poetry is religion; and although disfigured and misunderstood by the simplicity of men who believe in it without being capable of that imaginative interpretation of life in which its truth consists, yet this religion is even then often beneficent, because it colours life harmoniously with the ideal. Religion may falsely represent the ideal as a reality, but we must remember that the ideal, if not so represented, would be despised by the majority of men, who cannot understand that the value of things is moral, and who therefore attribute to what is moral a natural existence, thinking thus to vindicate its importance and value. But value lies in meaning, not in substance; in the ideal which things approach, not in the energy which they embody.
The highest poetry, then, is not that of the versifiers, but that of the prophets, or of such poets as interpret verbally the visions which the prophets have rendered in action and sentiment rather than in adequate words. That the intuitions of religion are poetical, and that in such intuitions poetry has its ultimate function, are truths of which both religion and poetry become more conscious the more they advance in refinement and profundity. A crude and superficial theology may confuse God with the thunder, the mountains, the heavenly bodies, or the whole universe; but when we pass from these easy identifications to a religion that has taken root in history and in the hearts of men, and has come to flower, we find its objects and its dogmas purely ideal, transparent expressions of moral experience and perfect counterparts of human needs. The evidence of history or of the senses is left far behind and never thought of; the evidence of the heart, the value of the idea, are alone regarded.
Take, for instance, the doctrine of transubstantiation. A metaphor here is the basis of a dogma, because the dogma rises to the same subtle region as the metaphor, and gathers its sap from the same soil of emotion. Religion has here rediscovered its affinity with poetry, and in insisting on the truth of its mystery it unconsciously vindicates the ideality of its truth. Under the accidents of bread and wine lies, says the dogma, the substance of Christ's body, blood, and divinity. What is that but to treat facts as an appearance, and their ideal import as a reality? And to do this is the very essence of poetry, for which everything visible is a sacrament—an outward sign of that inward grace for which the soul is thirsting.
In this same manner, where poetry rises from its elementary and detached expressions in rhythm, euphuism, characterization, and story-telling, and comes to the consciousness of its highest function, that of portraying the ideals of experience and destiny, then the poet becomes aware that he is essentially a prophet, and either devotes himself, like Homer or Dante, to the loving expression of the religion that exists, or like Lucretius or Wordsworth, to the heralding of one which he believes to be possible. Such poets are aware of their highest mission; others, whatever the energy of their genius, have not conceived their ultimate function as poets. They have been willing to leave their world ugly as a whole, after stuffing it with a sufficient profusion of beauties. Their contemporaries, their fellow-countrymen for many generations, may not perceive this defect, because they are naturally even less able than the poet himself to understand the necessity of so large a harmony. If he is short-sighted, they are blind, and his poetic world may seem to them sublime in its significance, because it may suggest some partial lifting of their daily burdens and some partial idealization of their incoherent thoughts.
Such insensibility to the highest poetry is no more extraordinary than the corresponding indifference to the highest religion; nobility and excellence, however, are not dependent on the suffrage of half-baked men, but on the original disposition of the clay and the potter; I mean on the conditions of the art and the ideal capacities of human nature. Just as a note is better than a noise because, its beats being regular, the ear and brain can react with pleasure on that regularity, so all the stages of harmony are better than the confusion out of which they come, because the soul that perceives that harmony welcomes it as the fulfilment of her natural ends. The Pythagoreans were therefore right when they made number the essence of the knowable world, and Plato was right when he said harmony was the first condition of the highest good. The good man is a poet whose syllables are deeds and make a harmony in Nature. The poet is a rebuilder of the imagination, to make a harmony in that. And he is not a complete poet if his whole imagination is not attuned and his whole experience composed into a single symphony.
For his complete equipment, then, it is necessary, in the first place, that he sing; that his voice be pure and well pitched, and that his numbers flow; then, at a higher stage, his images must fit with one another; he must be euphuistic, colouring his thoughts with many reflected lights of memory and suggestion, so that their harmony may be rich and profound; again, at a higher stage, he must be sensuous and free, that is, he must build up his world with the primary elements of experience, not with the conventions of common sense or intelligence; he must draw the whole soul into his harmonies, even if in doing so he disintegrates the partial systematizations of experience made by abstract science in the categories of prose. But finally, this disintegration must not leave the poet weltering in a chaos of sense and passion; it must be merely the ploughing of the ground before a new harvest, the kneading of the clay before the modelling of a more perfect form. The expression of emotion should be rationalized by derivation from character and by reference to the real objects that arouse it—to Nature, to history, and to the universe of truth; the experience imagined should be conceived as a destiny, governed by principles, and issuing in the discipline and enlightenment of the will. In this way alone can poetry become an interpretation of life and not merely an irrelevant excursion into the realm of fancy, multiplying oar images without purpose, and distracting us from our business without spiritual gain.
If we may then define poetry, not in the formal sense of giving the minimum of what may be called by that name, but in the ideal sense of determining the goal which it approaches and the achievement in which all its principles would be fulfilled, we may say that poetry is metrical and euphuistic discourse, expressing thought which is both sensuous and ideal.
Such is poetry as a literary form; but if we drop the limitation to verbal expression, and think of poetry as that subtle fire and inward light which seems at times to shine through the world and to touch the images in our minds with ineffable beauty, then poetry is a momentary harmony in the soul amid stagnation or conflict,—a glimpse of the divine and an incitation to a religious life.
Religion is poetry become the guide of life, poetry substituted for science or supervening upon it as an approach to the highest reality. Poetry is religion allowed to drift, left without points of application in conduct and without an expression in worship and dogma; it is religion without practical efficacy and without metaphysical illusion. The ground of this abstractness of poetry, however, is usually only its narrow scope; a poet who plays with an idea for half an hour, or constructs a character to which he gives no profound moral significance, forgets his own thought, or remembers it only as a fiction of his leisure, because he has not dug his well deep enough to tap the subterraneous springs of his own life. But when the poet enlarges his theatre and puts into his rhapsodies the true visions of his people and of his soul, his poetry is the consecration of his deepest convictions, and contains the whole truth of his religion. What the religion of the vulgar adds to the poet's is simply the inertia of their limited apprehension, which takes literally what he meant ideally, and degrades into a false extension of this world on its own level what in his mind was a true interpretation of it upon a moral plane.
