Two particular phases of this educative power should be specifically mentioned. The objective presentation of emotion in literature, as has been often observed, corrects the perspective of our own lives, as does also the action which it envelops; and by showing to us emotion in intense energy, which by this intensity corresponds to high type and important plot, and in a compass far greater than is normal in ordinary life, the portrayal leads us better to bear and more justly to estimate the petty trials, the vexations, the insignificant experiences of our career; we see our lives in a truer relation to life in general, and avoid an overcharged feeling in regard to our private fortune. And, secondly, the subjective emotion in ourselves is educative in the point that by this outlet we go out of ourselves in sympathy, lose our egoism, and become one with man in general. This is an escape; but not such as has been previously spoken of, for it is not a retreat. There is no escape for us, except into the lives of others. In nature it is still our own face we see; and before the ideal creations of art we are still aware, for all our contemplation, of the ineffable yearning of the thwarted soul, of the tender melancholy, the sadness in all beauty, which is the measure of our separation therefrom, and is fundamental in the poetic temperament. This is that pain, which Plato speaks of—the pain of the growing of the wings of the spirit as they unfold. But in passing into the lives of other men, in sharing their joys, in taking on ourselves the burden of humanity, we escape from our self-prison, we leave individuality behind, we unite with man in common; so we die to ourselves in order to live in lives not ours. In literature, sympathy and that imagination by which we enter into and comprehend other lives are most trained and developed, made habitual, instinctive, and quick. It begins to appear, I trust, that ideal art is not only one with our nature intellectually, but in all ways; it is the path of the spirit in all things. Moreover, emotion is in itself simple; it does not need generalization, it is the same in all. It is rather a means of universalizing the refinements of the intellect, the substantive idealities of imagination, by enveloping them in an elementary, primitive feeling which they call forth. Poetry, therefore, especially deals, as Wordsworth pointed out, in the primary affections, the elementary passions of mankind; and, whatever be its intellectual contents of nature or human events, calls these emotions forth as the master-spirit of all our seeing. Emotion is more fundamental in us than knowledge; it is more powerful in its working; it underlies more deliberate and conscious life in the mind, and in most of us it rules, as it influences in all. It is natural, therefore, to find that its operation in art is of graver importance than that of the intellectual faculty so far as the broad power of art over men is concerned.

Another special point arises from the fact that some emotions are painful, and the question is raised how in literature painful emotions become a pleasure. Aristotle's doctrine in respect to certain of these emotions, tragic pity and terror, is well known, though variously interpreted. He regards such emotions as a discharge of energy, an exhaustion and a relief, in consequence of which their disturbing presence is less likely to recur in actual life; it is as if emotional energy accumulated, as vital force is stored up and requires to be loosed in bodily exercise; but this, except in the point that pity and terror, if they do accumulate in their particular forms latently, are specifically such as it is wise to be rid of, does not differentiate emotion from the rest of our powers in all of which there is a similar pleasure in exercising, an exhaustion and a relief, with less liability of immediate recurrence; this belongs to all expenditure of life. It is not credible to me that painful emotion, under the illusions of art, can become pleasurable in the common sense; what pleasure there is arises only in the climax and issue of the action, as in case of the drama when the restoration of the order that is joyful, beautiful, right, and wise occurs; in other words, in the presence of the final poetic justice or reconciliation of the disturbed elements of life. But here we come upon darker and mysterious aspects of our general subject, now to be slightly touched. Tragedy dealing with the discords of life must present painful spectacles; and is saved to art only by its just ending. Comedy, which similarly deals with discords, is endurable only while these remain painless. Both imply a defect in order, and neither would have any place in a perfect world, which would be without pity, fear, or humour, all of which proceed from incongruities in the scheme. Tragedy and comedy belong alike to low civilizations, to wicked, brutal, or ridiculous types of character and disorderly events, to the confusion, ignorance, and ignominies of mankind; the refinement of both is a mark of progress in both art and civilization, and foretells their own extinction, unless indeed the principle of evil be more deeply implanted in the universe than we fondly hope; pathos and humour, which are the milder and the kindlier forms of tragedy and comedy, must also cease, for both are equally near to tears. But before leaving this subject it is interesting to observe how in the Aristotelian scheme of tragedy, where it was little thought of, the appeal is made to man's whole nature as here outlined—the plot replying to reason, the scene to the sense of beauty, the katharsis to the emotions, and poetic justice to the will, which thus finds its model and exemplar in the supremacy of the moral law in all tragic art.

This, then, being the nature of the ideal world in its whole range commensurate with our being, and these the methods of its intellectual and emotional appeal, it remains to examine the world of art in itself, and especially its genesis out of life. The method by which it is built up has long been recognized to be that of imitation of the actual, as has been assumed hitherto in the statement that all art is concrete. But the concrete which art creates is not a copy of the concrete of life; it is more than this. The mind takes the particulars of the world of sense into itself, generalizes them, and frames therefrom a new particular, which does not exist in nature; it is, in fact, nature made perfect in an imagined instance, and so presented to the mind's eye, or to the eye of sense. The pleasure which imitation gives has been often and diversely analyzed; it may be that of recognition, or that of new knowledge satisfying our curiosity as if the original were present, or that of delight in the skill of the artist, or that of interest in seeing how his view differs from our own, or that of the illusion created for us; but all these modes of pleasure exist when the imitation is an exact copy of the original, and they do not characterize the artistic imitation in any way to differentiate its peculiar pleasure. It is that element which artistic imitation adds to actuality, the difference between its created concrete and the original out of which that was developed, which gives the special delight of art to the mind. It is the perfection of the type, the intensity of the emotion, the inevitability of the plot,—it is the pure and intelligible form disclosed in the phases and movement of life, disengaged and set apart for the contemplation of the mind,—it is the purging of the sensual eye, enabling it to see through the mind as the mind first saw through it, which renders the world of art the new vision it is, the revelation accomplished by the mind for the senses. If the world of art were only a reduplication of life, it would give only the pleasures that have been mentioned; but its true pleasure is that which it yields from its supersensual element, the reason which has entered into it with ordering power. In the world thus created there will remain the imperfections which are due to the limitation of the artist, in knowledge, skill, and choice.

It will be said at once that all these concrete representations necessarily fail to realize the artist's thought, and are inadequate, inferior in exactness, to scientific and philosophic knowledge; in a measure this is true, and would be important if the method of art were demonstrative, instead of being, as has been said, experimental and inductive. So, too, all thinkers, using the actual world in their processes, are at a disadvantage. The figures of the geometer, the quantities of the chemist, the measurements of the astronomer, are inexact approximations to their equivalent in the mind. Art, as an embodiment in mortal images, is subject to the conditions of mortality. Hence arises its human history, the narrative of its rise, climax, and decline in successive ages. The course of art is known; it has been run many times; it is a simple matter. At first art is archaic, the sensible form being rudely controlled by the artist's hand; it becomes, in the second stage, classical, the form being adequate to the thought, a transparent expression; last, it is decadent, the form being more than the thought, dwarfing it by usurping attention on its own account. The peculiar temptation of technique is always to elaboration of detail; technique is at first a hope, it becomes a power, it ends in being a caprice; and always as it goes on it loses sight of the general in its rendering, and dwells with a near eye on the specific. Nor is this attention to detail confined to the manner; the hand of the artist draws the mind after it, and it is no longer the great types of manhood, the important fates of life, the primary emotions in their normal course, that are in the foreground of thought, but the individual is more and more, the sensational in plot, the sentimental in feeling. This tendency to detail, which is the hallmark of realism, constitutes decline. It arises partly from the exhaustion of general ideas, from the search for novelty of subject and sensation, from the special phenomena of a decaying society; but, however manifold may be the causes, the fact of decline consists in the lessened scope of the matter and the increased importance of the form, both resulting in luxuriant detail. Ideas as they lose generality gain in intensity, but in the history of art this has not proved a compensation. In Greece the three stages are clearly marked both in matter and manner, in Aeschylus, Sophocles, and Euripides; in England less clearly in Marlowe, Shakspere, and Webster. How monstrous in the latter did tragedy necessarily become! yet more repulsive in his tenderer companion-spirit, Ford. In Greek sculpture, passing into convulsed and muscular forms or forms of relaxed voluptuousness, in Italian painting, in the romantic poetry of this century with us, the same stages are manifest. Age parallels age. Tennyson in artistic technique is Virgilian, we are aware of the style; but both Virgil and Tennyson remain classic in matter, in universality, and the elemental in man. Browning in substance is Euripidean, being individualistic, psychologic, problematic, with special pleading; classicism had departed from him, and left not even the style behind. The great opposition lies in the subject of interest. Is it to know ourselves in others? Then art which is widely interpretative of the common nature of man results. Is it to know others as different from ourselves? Then art which is specially interpretative of abnormal individuals in extraordinary environments results. This is the opposition between realism and idealism, while both remain in the limits of art, as these terms are commonly used. It belongs to realism to tend to the concrete of narrow application, but with fulness of special trait or detail. It belongs to idealism to tend to the concrete of broad application, but without peculiarity. The trivial on the one hand, the criminal on the other, in the individual, are the extremes of realistic art, while idealism rises to an almost superhuman emphasis on that wisdom and virtue, and the beauty clothing them, which are the goal of a nation's effort. Race-ideas, or generalizations of a compact and homogeneous people summing up their serious interpretations of life, their moral choices, their aspiration and hope in the lines of effort that seem to them highest, are the necessary matter of idealism; when these are expressed they are the Greek spirit, the Roman genius, great types of humanity on the impersonal, the national scale. As these historic generalizations dissolve in national decay, art breaks up in individual portrayal of less embracing types; the glorification of the Greek man in Achilles yields place to the corruptions of the homunculus; and in general the literature of nationality gives way to the unmeaning and transitory literature of a society interested in its vices, superstitions, and sensations. In each age some genius stands at the centre of its expression, a shining nucleus amid its planetary stars; such was Dante, such Virgil, such Shakspere. Few indeed are the races that present the spectacle of a double-sun in their history, as the Hebrews in Psalm and Gospel, the Greeks in Homer and in Plato. And yet, all this enormous range of life and death, this flowering in centuries of the human spirit in its successive creations, reposes finally on the more or less general nature of the concretes used in its art, on their broad or narrow truth, on their human or individualistic significance. The difference between idealism and realism is not more than a question which to choose. At the further end and last remove, when all art has been resolved into a sensation, an effect, lies impressionism, which, by its nature, is a single phase at a single moment as seen by a single being; but even then, if the mind be normal, if the phase be veritable, if the moment be that of universal beauty which Faust bade be eternal, the artistic work remains ideal; but on the other hand, it is usually the eccentric mind, the abnormal phase, the beauty of morbid sensation that are rendered; and impressionism becomes, as a term, the vanishing-point of realism into the moment of sense.

The world of art, to reach its last limitation, through all this wide range is in each creation passed through the mind of the artist and presented necessarily under all the conditions of his personality. His nature is a term in the process, and the question of imperfection or of error, known as the personal equation, arises. Individual differences of perceptive power in comprehending what is seen, and of narrative skill, or in the plastic and pictorial arts of manual dexterity, import this personal element into all artistic works, the more in proportion to the originality of the maker and the fulness of his self-expression. In rendering from the actual such error is unavoidable, and is practically admitted by all who would rather see for themselves than take the account of a witness, and prefer the original to any copy of it, though they thereby only substitute their own error for that of the artist. This personal error, however, is easily corrected by the consensus of human nature.

The differences in personality go far deeper than this common liability of humanity to mere mistakes in sight and in representation. The isolating force that creates a solitude round every man lies in his private experience, and results from his original faculties and the special conditions of his environment, his acquired habits of attending to some things rather than others open to him, the choices he has made in the past by which his view of the world and his interest in it have been determined. Memory, the mother of the Muses, is supreme here; a man's memory, which is the treasury of his chosen delights in life, characterizes him, and differentiates his work from that of others, because he must draw on that store for his materials. Thus a man's character, or, what is more profound, his temperament, acting in conjunction with the memory it has built up for itself, is a controlling force in artistic work, and modifies it in the sense that it presents the universal truth only as it exists in his personality, in his apprehension of it and its meaning.

Genius is this power of personality, and exists in proportion as the man differs from the average in ways that find significant expression. This difference may proceed along two lines. It may be aberration from normal human nature, due to circumstances or to inherent defect or to a thousand causes, but existing always in the form of an inward perversion approaching disease of our nature; such types of genius are pathological and may be neglected. It may, on the other hand, be development of normal human nature in high power, and it then exists in the form of inward energy, showing itself in great sensitiveness to outward things, in mental power of comprehension, in creative force of recombination and expression. Of genius of this last sort the leaders of the human spirit are made. The basis of it is still, human faculty dealing with the universe—the same faculty, the same universe, that are common to mankind; but with an extraordinary power, such that it can reveal to men at large what they of themselves might never have arrived at, can advance knowledge and show forth goals of human hope, can in a word guide the race. The isolation of such a nature is necessarily profound, and intense loneliness has ever been a characteristic of genius. The solvent of all personality, however, lies at last in this fact of a common world and a common faculty for all, resulting in an experience intelligible to all, even if unshared by them. The humanity of genius constitutes its sanity, and is the ground of its usefulness; though it lives in isolation, it does so only as an advanced outpost may; it expects the advent of the race behind and below it, and shows there its signal and sounds there its call. Its escape from personality lies in its identifying itself with the common order in which all souls shall finally be merged and be at one. The limitations of genius are consequently not so much limitations as the abrogation of limits in the ordinary sense; its originality of insight, interpretation, and expression broadens the human horizons and enriches the fields within them; it tells us what we may not have known or felt or guessed, but what we shall at last understand. Thus, as the theory of art is most fixed in the doctrine of order, so here it is most flexible in the doctrine of personality, through which that order is most variously set forth and illustrated. Imitation, so far from becoming a defective or false method because of personality, is really made catholic by it, and gains the variety and breadth that characterizes the artistic world as a whole.

The element of self which thus enters into every artistic work has different degrees of importance. In objective art, it is clear that it enters valuably in proportion as the universe is seized by a mind of right reason, of profound penetration, of truthful imagination; and if the work be presented enveloped in a subjective mood, while it remains objective in contents, as in Virgil the mood pervades the poem so deeply as to be a main part of it, then the mood must be one of those felt or capable of being felt universally,—the profound moods of the meditative spirit in grand works, the common moods of simple joy and sorrow in less serious works. In proportion as society develops, whether in historic states singly or in the progress of mankind, the direct expression of self for its own sake becomes more usual; literature becomes more personal or purely subjective. If the poet's private story be one of action, it is plain that it has interest only as if it were objectively rendered, from its being illustrative of life in general; so, too, if the felt emotion be given, this will have value from its being treated as typical; and, in so far as the intimate nature of the poet is variously given as a whole in his entire works, it has real importance, has its justification in art, only in so far as he himself is a high normal type of humanity. The truth of the matter is, in fact, only a detail of the general proposition that in art history has no value of its own as such; for the poet is a part of life that is, and his nature and career, like that of any character or event in history, have no artistic value beyond their universal significance. In such self-portraiture there may be sometimes the depicting of a depraved nature, such as Villon; but such a type takes its place with other criminal types of the imagination, and belongs with them in another sphere.

This element of self finds its intense expression in lyrical love-poetry, one of the most enduring forms of literature because of its elementariness and universality; but it is also found in other parts of the emotional field. In seeking concrete material for lyrical use the poet may take some autobiographical incident, but commonly the world of inanimate nature yields the most plastic mould. It is a marvellous victory of the spirit over matter when it takes the stars of heaven and the flowers of earth and makes them utter forth its speech, less as it seems in words of human language than in the pictured hieroglyph and symphonic movement of natural things; for in such poetry it is not the vision of nature, however beautiful, that holds attention; it is the colour, form, and music of things externalizing, visualizing the inward mood, emotion, or passion of the singer. Nature is emptied of her contents to become the pure inhabitancy of one human soul. The poet's method is that of life itself, which is first awakened by the beauty without to thought and feeling; he expresses the state evoked by that beauty and absorbing it. He identifies himself with the objects before him through his joy in them, and entering there makes nature translucent with his own spirit.

Shelley's Ode to the West Wind is the eminent example of such magical power. The three vast elements, earth, air, and water, are first brought into a union through their connection with the west wind; and, the wind still being the controlling centre of imagination, the poet, drawing all this limitless and majestic imagery with him, by gradual and spontaneous approaches identifies himself at the climax of feeling with the object of his invocation,—
