Vitally to appreciate what poetry is, it is necessary to realize what are its relations to life. Looked at in itself its essentials are emotion which is capable of taking entire possession of the consciousness, and the embodiment of this emotion by the combined effects of imaginative language and melodious form. It is still needful, however, to consider how this art acts upon human beings, and why there has been claimed for it so proud a pre-eminence among the arts.

Why, for instance, should Emerson speak of the embodiment of mere emotion as "the only verity," Wordsworth as "the breath and finer spirit of all knowledge," and why does Mrs. Browning call poets "the only truth-tellers"? The answer briefly is: Because consciousness is identical with emotion, and consciousness is life. For all practical purposes man exists but in that he feels. The universe concerns him in so far as it touches his feelings, and it concerns him no farther. That is for man most essential which comes most near to the conditions of his existence. Pure and ideal emotion is essential truth in the sense that it approaches most nearly to the consciousness,—that is, to the actual being of the race.

I am aware that this sounds dangerously like an attempt to be darkly metaphysical; but it is impossible to talk on high themes without to some extent using high terms. It is useless to hope to put into words all the mysteries of the relations of art to life, yet it is not impossible to approximate somewhat to what must be the truth of the matter, although in doing it one inevitably runs the risk of seeming to attempt to say what cannot be said. What I have been endeavoring to convey will perhaps be plainer if I say that for purposes of our discussion man is practically alive only in so far as he realizes life. This realization of life, this supreme triumph of inner consciousness, comes to him through his feelings,—indeed, is perhaps to be considered as identical with his feelings. His sensations affect him only by the emotions which they excite. His emotion, in a word, is the measure of his existence. Now the emotion of man always responds, in a degree marked by appreciation, to certain presentations of the relation of things, to certain considerations of the nature of human life, and above all to certain demonstrations of the possibilities of human existence. If these are made actual and clear to the mind, they cannot fail to arouse that engrossing realization which is the height of consciousness. To enable a man to seize with his imagination the ideal of love or hate, of fear or courage, of shame or honor, is to make him kindle and thrill. It is to make him for the time being thoroughly and richly alive, and it is to increase greatly his power of essential life. These are the things which most deeply touch human creatures; they are the universal in that they appeal to all sane hearts and minds; they are the eternal as measured by mortal existence because they have power to touch the men of all time; hence they are the real truths; they are, for beings under the conditions of earthly existence, the only verities.

The ordinary life of man is not unlike the feeble flame of a miner's lamp, half smothered in some underground gallery until a draught of vital air kindles it into sudden glow and sparkle. Most human beings have but a dull flicker of half-alive consciousness until some outward breath causes it to flash into quick and quivering splendor. Poetry is that divine air, that breeze from unscaled heights of being, the kindling breath by which the spark becomes a flame.

It is but as a means of conveying the essential truth which is the message of poetry, that the poet employs obvious truth. The facts which impress themselves upon the outer senses are to him merely a language by means of which he seeks to impart the higher facts that are apprehended only by the inner self; those facts of emotion which it is his office as a seer to divine and to interpret. The swineherd and the wandering minstrel saw the same wood and sky and lake; but to one they were earth and air and water; while to the other they were the outward and visible embodiment of the spirit of beauty which is eternal though earth and sea and sky vanish. To Peter Bell the primrose by the river's brim was but a primrose and nothing more; to the poet it was the symbol and the embodiment of loveliness, the sign of an eternal truth. To the laborer going afield in the early light the dewdrops are but so much water, wetting unpleasantly his shoes; to Browning it was a symbol of the embodiment in woman of all that is pure and holy when he sang:—

There's a woman like a dew-drop, she's so purer than the purest.

It is evident from what has been said that in reading poetry it is necessary to penetrate through the letter to the spirit. I have already spoken at length in a former lecture upon the need of knowing the language of literature, and of being in sympathy with the mood of the writer. This is especially true in regard to poetry, since poetry becomes great in proportion as it deals with the spirit rather than with the letter. "We are all poets when we read a poem well," Carlyle has said. It is only by entering into the mood and by sharing the exaltation of the poet that we are able to appreciate his message. A poem is like a window of stained glass. From without one may be able to gain some general idea of its design and to guess crudely at its hues; but really to perceive its beauty, its richness of design, its sumptuousness of color, one must stand within the very sanctuary itself.

It is partly from the lack of sensitiveness of the imagination of the reading public, I believe, that in the latter half of this century the novel has grown into a prominence so marked. The great mass of readers no longer respond readily to poetry, and fiction is in a sense a simplification of the language of imagination so that it may be comprehended by those who cannot rise to the heights of verse. In this sense novels might almost be called the kindergarten of the imagination. In fiction, emotional experiences are translated into the language of ordinary intellectual life; whereas in poetry they are phrased in terms of the imagination, pure and simple. There can be no question of the superiority of the means employed by the poet. Much which is embodied in verse cannot be expressed by prose of any sort, no matter how exalted that prose may be; but for the ordinary intelligence the language of prose is far more easily comprehensible.

What I have been saying, however, may seem to be so general and theoretical that I may be held not yet fairly to have faced that issue at which I hinted in the beginning, the issue which Philistine minds raise bluntly: What is the use of poetry? Philistines are willing to concede that there is a sensuous pleasure to be gained from verse. They are able to perceive how those who care for such things may find an enervating enjoyment in the linked sweetness of cadence melting into cadence, in musical line and honeyed phrase. What they are utterly unable to understand is how thoughtful men, men alive to the practical needs and the real interests of the race, can speak of poetry as if it were a thing of genuine importance in the history and development of mankind. It would not be worth while to attempt an answer to this for the benefit of the Philistines. They are a folk who are so completely ignorant of the higher good of life that it is impossible to make them understand. Their conception of value does not reach beyond pecuniary and physical standards; they comprehend nothing which is not expressed in material terms. One who attempted to describe a symphony to a deaf man would not be more at a loss for terms than must be he who attempts to set forth the worth of art to those ignorant of real values. The question may be answered, but to those who most need to be instructed in regard to Æsthetic values any answer must forever remain unintelligible.

There are, however, many sincere and earnest seekers after truth who are unable to clear up their ideas when they come in contact, as they must every day, with the assumption that poetry is but the plaything of idle men and women, a thing not only unessential but even frivolous. For them it is worth while to formulate some sort of a statement; although to do this is like making the attempt to declare why the fragrance of the rose is sweet or why the hue of its petals gives delight.

In the first place, then, the use of poetry is to nourish the imagination. I have spoken earlier of the impossibility of fulfilling the higher functions of life without this faculty. A common error regards imagination as a quality which has to do with rare and exceptional experiences; as a power of inventing whimsical and impossible thoughts; as a sort of jester to beguile idle moments of the mind. In reality imagination is to the mental being what blood is to the physical man. Upon it the intellect and the emotional consciousness alike depend for nourishment. Without it the mind is powerless to seize or to make really its own anything which lies outside of actual experience. Without it the broker could not so fully realize his cunning schemes as to manipulate the market and control the price of stocks; without it the inventor could devise no new machine, the scientist grasp no fresh secret of laws which govern the universe. It is the divine power in virtue of which man subdues the world to his uses. In a word, imagination is that faculty which distinguishes man from brute.

It is the beginning of wisdom to know; it is the culmination of wisdom to feel. The intellect accumulates; the emotion assimilates. What we learn, we possess; but what we feel, we are. The perception acquires, and the imagination realizes; and thus it is that only through the imagination can man build up and nourish that inner being which is the true and vital self. To cultivate the imagination, therefore, is an essential—nay, more; it is the one essential means of insuring the progression of the race. This is the great office of all art, but perhaps most obviously is it the noble prerogative and province of poetry. "In the imagination," wrote Coleridge, "is the distinguishing characteristic of man as a progressive being." To kindle into flame the dull embers of this god-like attribute is the first office of poetry; and were this all, it would lift the art forever above every cumbering material care and engrossing intellectual interest.

In the second place, the use of poetry is to give man knowledge of his unrecognized experiences or his unrealized capacities of feeling. The poet speaks what many have felt, but what none save he can say. He accomplishes the hitherto impossible. He makes tangible and subject the vague emotions which disquiet us as if they were elusive ghosts haunting the dwelling of the soul, unsubdued and oppressive in their mystery. The joy of a moment he has fixed for all time; the throb gone almost before it is felt he has made captive; to the evasive emotion he has given immortality. In a word, it is his office to confer upon men dominion over themselves.

Third, it is poetry which nourishes and preserves the optimism of the race. Poetry is essentially optimistic. It raises and encourages by fixing the mind upon the possibilities of life. Even when it bewails what is gone, when it weeps lost perfection, vanished joy, and crushed love, the reader receives from the poetic form, from the uplift of metrical inspiration, a sense that the possibilities of existence overwhelm individual pain. The fact that such blessings could and may exist is not only consolation when fate has wrenched them away, but the vividness with which they are recalled may almost make them seem to be relived. That

is not the whole story. In times of deepest woe it is this very remembrance which makes it possible to live on at all. The unconscious and the inevitable lesson of all true art, moreover, is that the possibility of beauty in life is compensation for the anguish which its existence entails. The poet who weeps for the lost may have no word of comfort to offer, but the fact that life itself is of supreme possibilities is shown inevitably and persuasively by the fact that he is so deeply moved. He could not be thus stricken had he not known very ecstasies of joy; and his message to the race is that such bliss has been and thus may be again. More than this, the fact that he in his anguish instinctively turns to art is the most eloquent proof that however great may be the sorrows of life there is for them an alleviating balm in Æsthetic enjoyment. He may speak of

but with the very thought of the brevity is coupled an exquisite sense of both beauty and joy in ever fresh renewal, so that the reader knows a subtle thrill of pleasure even at the mention of pain. Poe's proposition that poetry should be restricted to sorrowful themes probably arose from a more or less conscious feeling that the expression of despair is the surest means of conveying vividly a sense of the value of what is gone; and whether Poe went so far as to realize it or not the fact is that the passion of loss most surely expresses the possible bliss of possession. Even when it would, art cannot deny the worth and the glory of existence. The word of denial is chanted to a strain which inspires and affirms. Even when he would be most pessimistic the genuine poet must perforce preach in deathless tones the gospel of optimism.

Fourth, poetry is the original utterance of the ideas of the world. It is easy and not uncommon to regard the art of the poet as having little to do with the practical conduct of life; yet there is no man in civilization who does not hold opinions and theories, thoughts and beliefs, which he owes to the poets. Thought is not devised in the marketplace. What thinkers have divined in secret is there shown openly by its results. Every poet of genius remakes the world. He leaves the stamp of his imagination upon the whole race, and philosophers reason, scientists explore, money-changers scheme, tradesmen haggle, and farmers plough or sow, all under conditions modified by what has been divulged in song. The poet is the great thinker, whose thought, translated, scattered, diluted, spilled upon the ground and gathered up again, is the inspiration and the guide of mankind.

If this seem extravagant, think for a little. Reflect in what civilization differs from savagery; consider not the accidental and outward circumstance, but the fundamental causes upon which these depend. If you endeavor to find adequately expressed the ideals of honor, of truth, of love, and of aspiration which are behind all the development of mankind, it is to the poets that you turn instinctively. It is possible to go farther than this. Knowledge is but a perception of relations. The conception of the universe is too vast to be assimilated all at once, but every perception of the way in which one part is related to another, one fact to another, one thing to the rest, helps toward a realization of the ultimate truth. It is the poet who first discerns and proclaims the relations of those facts which the experience of the race accumulates. From the particular he deduces the general, from the facts he perceives the principles which underlie them. The general, that is, in its relation to that emotional consciousness which is the real life of man; the principles which take hold not upon material things only, but upon the very conditions of human existence. All abstract truth has sprung from poetry as rain comes from the sea. Changed, diffused, carried afar and often altered almost beyond recognition, the thought of the world is but the manifestation of the imagination of the world; and it has found its first tangible expression in poetry.

Fifth, poetry is the instructor in beauty. No small thing is human happiness, and human happiness is nourished on beauty. Poetry opens the eyes of men to loveliness in earth and sky and sea, in flower and weed, in tree and rock and stream, in things common and things afar alike. It is by the interpretation of the poet that mankind in general is aware of natural beauty; and it is hardly less true that the beauty of moral and emotional worlds would be practically unknown were it not for these high interpreters. The race has first become aware of all ethereal and elusive loveliness through the song of the poet, sensitive to see and skillful to tell. For its beauty in and of itself, and for its revelation of the beauty of the universe, both material and intangible, poetry is to the world a boon priceless and peerless.

Sixth, poetry is the creator and preserver of ideals. The ideal is the conception of the existence beyond what is of that which may and should be. It is the measure of the capability of desire. "Man's desires are limited by his perceptions," says William Blake; "none can desire what he has not perceived." What man can receive, what it is possible for him to enjoy, is limited to what he is able to wish for. The ideal is the highest point to which his wish has been able to attain, and upon the advancement of this point must depend the increasing of the possibilities of individual experience. With the growth of ideals, moreover, comes the constant, however slow, realization of them. So true is this that it almost affords a justification of the belief that whatever mankind really desires must in the end be realized from the very fact that it is desired. Be that as it may, an ideal is the perception of a higher reality. It is the recognition of essential as distinguished from accidental truth; the comprehension of the eternal principle which must underlie every fact. It is a realization of the meaning of existence; a piercing through the transient appearance to the fundamental and the enduring. The reader who finds himself caught away like St. Paul to the third heaven—"whether in the body I cannot tell; or whether out of the body I cannot tell"—has no need to ask whether life is merely eating and drinking, getting and spending, marrying and giving in marriage. He has for that transcendent moment lived the real life; he has tasted the possibilities of existence; he has for one glorious instant realized the ideal. When a poem has carried him out of himself and the material present which we call the real, then the verse has been for him as a chariot of fire in which he has been swirled upward to the very heart of the divine.

When not actually under the influence of this high exalting power of poetry most men have a strange reluctance to admit that it is possible for them to be so moved; and thus it may easily happen that what has just been said may seem to the reader extravagant and florid. There are happily few, however, to whom there have not come moments of inner illumination, few who cannot if they will call up times when the imagination has carried them away, and the delight of being so borne above the actual was a revelation and a joy not easily to be put into word. Recalling such an experience, you will not find it difficult to understand what is meant by the claim that poetry creates in the mind of man an ideal which in turn it justifies also.

Lastly and above all, the use of poetry is—poetry.

It is vain to endeavor to put into word the worth and office of poetry. At the last we are brought face to face with the fact that anything short of itself is inadequate to do it justice. To read a single page of a great singer is more potent than to pore over volumes in his praise. A single lyric puts to shame the most elaborate analysis or the most glowing eulogy; in the end there is no resource but to appeal to the inner self which is the true man; since in virtue of what is most deep and noble in the soul, each may perceive for himself that poetry is its own supreme justification; that there is no need to discuss the relation of poetry to life, since poetry is the expression of life in its best and highest possibilities.
