This plastic moment of the mind, when we become aware of the artificiality and inadequacy of what common sense perceives, is the true moment of poetic opportunity,—an opportunity, we may hasten to confess, which is generally missed. The strain of attention, the concentration and focussing of thought on the unfamiliar immediacy of things, usually brings about nothing but confusion. We are dazed, we are filled with a sense of unutterable things, luminous yet indistinguishable, many yet one. Instead of rising to imagination, we sink into mysticism.
To accomplish a mystical disintegration is not the function of any art; if any art seems to accomplish it, the effect is only incidental, being involved, perhaps, in the process of constructing the proper object of that art, as we might cut down trees and dig them up by the roots to lay the foundations of a temple. For every art looks to the building up of something. And just because the world built up by common sense and natural science is an inadequate world (a skeleton which needs the filling of sensation before it can live), therefore the moment when we realize its inadequacy is the moment when the higher arts find their opportunity. When the world is shattered to bits they can come and "build it nearer to the heart's desire."
The great function of poetry, which we have not yet directly mentioned, is precisely this: to repair to the material of experience, seizing hold of the reality of sensation and fancy beneath the surface of conventional ideas, and then out of that living but indefinite material to build new structures, richer, finer, fitter to the primary tendencies of our nature, truer to the ultimate possibilities of the soul. Our descent into the elements of our being is then justified by our subsequent freer ascent toward its goal; we revert to sense only to find food for reason; we destroy conventions only to construct ideals.
Such analysis for the sake of creation is the essence of all great poetry. Science and common sense are themselves in their way poets of no mean order, since they take the material of experience and make out of it a clear, symmetrical, and beautiful world; the very propriety of this art, however, has made it common. Its figures have become mere rhetoric and its metaphors prose. Yet, even as it is, a scientific and mathematical vision has a higher beauty than the irrational poetry of sensation and impulse, which merely tickles the brain, like liquor, and plays upon our random, imaginative lusts. The imagination of a great poet, on the contrary, is as orderly as that of an astronomer, and as large; he has the naturalist's patience, the naturalist's love of detail and eye trained to see fine gradations and essential lines; he knows no hurry; he has no pose, no sense of originality; he finds his effects in his subject, and his subject in his inevitable world. Resembling the naturalist in all this, he differs from him in the balance of his interests; the poet has the concreter mind; his visible world wears all its colours and retains its indwelling passion and life. Instead of studying in experience its calculable elements, he studies its moral values, its beauty, the openings it offers to the soul: and the cosmos he constructs is accordingly an ideal theatre for the spirit in which its noblest potential drama is enacted and its destiny resolved.
This supreme function of poetry is only the consummation of the method by which words and imagery are transformed into verse. As verse breaks up the prosaic order of syllables and subjects them to a recognizable and pleasing measure, so poetry breaks up the whole prosaic picture of experience to introduce into it a rhythm more congenial and intelligible to the mind. And in both these cases the operation is essentially the same as that by which, in an intermediate sphere, the images rejected by practical thought, and the emotions ignored by it, are so marshalled as to fill the mind with a truer and intenser consciousness of its memorable experience. The poetry of fancy, of observation, and of passion moves on this intermediate level; the poetry of mere sound and virtuosity is confined to the lower sphere; and the highest is reserved for the poetry of the creative reason. But one principle is present throughout,—the principle of Beauty,—the art of assimilating phenomena, whether words, images, emotions, or systems of ideas, to the deeper innate cravings of the mind.
Let us now dwell a little on this higher function of poetry and try to distinguish some of its phases.
The creation of characters is what many of us might at first be tempted to regard as the supreme triumph of the imagination. If we abstract, however, from our personal tastes and look at the matter in its human and logical relations, we shall see, I think, that the construction of characters is not the ultimate task of poetic fiction. A character can never be exhaustive of our materials: for it exists by its idiosyncrasy, by its contrast with other natures, by its development of one side, and one side only, of our native capacities. It is, therefore, not by characterization as such that the ultimate message can be rendered. The poet can put only a part of himself into any of his heroes, but he must put the whole into his noblest work. A character is accordingly only a fragmentary unity; fragmentary in respect to its origin,—since it is conceived by enlargement, so to speak, of a part of our own being to the exclusion of the rest,—and fragmentary in respect to the object it presents, since a character must live in an environment and be appreciated by contrast and by the sense of derivation. Not the character, but its effects and causes, is the truly interesting thing. Thus in master poets, like Homer and Dante, the characters, although well drawn, are subordinate to the total movement and meaning of the scene There is indeed something pitiful, something comic, in any comprehended soul; souls, like other things, are only definable by their limitations. We feel instinctively that it would be insulting to speak of any man to his face as we should speak of him in his absence, even if what we say is in the way of praise: for absent he is a character understood, but present he is a force respected.
In the construction of ideal characters, then, the imagination is busy with material,—particular actions and thoughts,—which suggest their unification in persons; but the characters thus conceived can hardly be adequate to the profusion of our observations, nor exhaustive, when all personalities are taken together, of the interest of our lives. Characters are initially imbedded in life, as the gods themselves are originally imbedded in Nature. Poetry must, therefore, to render all reality, render also the background of its figures, and the events that condition their acts. We must place them in that indispensable environment which the landscape furnishes to the eye and the social medium to the emotions.
The visible landscape is not a proper object for poetry. Its elements, and especially the emotional stimulation which it gives, may be suggested or expressed in verse; but landscape is not thereby represented in its proper form; it appears only as an element and associate of moral unities. Painting, architecture, and gardening, with the art of stage setting, have the visible landscape for their object, and to those arts we may leave it. But there is a sort of landscape larger than the visible, which escapes the synthesis of the eye; it is present to that topographical sense by which we always live in the consciousness that there is a sea, that there are mountains, that the sky is above us, even when we do not see it, and that the tribes of men, with their different degrees of blamelessness, are scattered over the broad-backed earth. This cosmic landscape poetry alone can render, and it is no small part of the art to awaken the sense of it at the right moment, so that the object that occupies the centre of vision may be seen in its true lights, coloured by its wider associations, and dignified by its felt affinities to things permanent and great. As the Italian masters were wont not to paint their groups of saints about the Virgin without enlarging the canvas, so as to render a broad piece of sky, some mountains and rivers, and nearer, perhaps, some decorative pile; so the poet of larger mind envelops his characters in the atmosphere of Nature and history, and keeps us constantly aware of the world in which they move.
The distinction of a poet—the dignity and humanity of his thought—can be measured by nothing, perhaps, so well as by the diameter of the world in which he lives; if he is supreme, his vision, like Dante's, always stretches to the stars. And Virgil, a supreme poet sometimes unjustly belittled, shows us the same thing in another form; his landscape is the Roman universe, his theme the sacred springs of Roman greatness in piety, consistancy, and law. He has not written a line in forgetfulness that he was a Roman; he loves country life and its labours because he sees in it the origin and bulwark of civic greatness; he honours tradition because it gives perspective and momentum to the history that ensues; he invokes the gods, because they are symbols of the physical and moral forces, by which Rome struggled to dominion.
