The Principles of Aesthetics Part 10

Or the novelist may insert a letter which we can read as if it were real. The resulting image of life will be clearer than any we could construct for ourselves; for the artist can report life more carefully than we could observe it; and he can make his characters more articulate in the expression of themselves than ordinary men, giving them a gift of tongues like his own. This last is especially characteristic of the drama, where sometimes, as in Shakespeare, men speak more like G.o.ds than like men. And we can listen to the intimate conversation of friends and lovers, upon which, in real life, we would not intrude.

This direct method of exposition through the description of acts and events and the record of conversations is the basis of every vivid story. It leaves the necessary inferences to the reader, just as life leaves them to the observer. In the hands of a master like Fontane, this method is incomparable; nothing can supplant it. It is the only method available for the dramatist, who, however, can make it still more effective through histrionic portrayal. Yet it does not suffice to satisfy our craving for knowledge of life, for only the broader, more obvious feelings can be inferred from the acts of men; the subtler and more remote escape. Even in conversation these cannot all be revealed; for many of them are too intimate to be spoken, and many again are unknown even to those who hold them. To-day we ask of the novelist that he disclose the finest, most hidden tissues of the soul.

To this end, the microscopy of a.n.a.lysis, the so-called psychological method, must be employed. The novelist must perform upon his characters the same sort of dissection that we perform when, introspecting, we seek out the obscurer grounds of our conduct. And in the pursuit of this knowledge the novelist can oftentimes do better with his characters than we can do with ourselves. For utter sincerity regarding ourselves is impossible; the desire to think well of ourselves prevents us from recognizing the truth about ourselves. The novelist, on the contrary, can be unprejudiced and can know fully what he himself is creating.

In order to accomplish this same purpose, the dramatist has to introduce bits of self-a.n.a.lysis, unusually sincere and penetrating, spoken aloud,--in the old style, monologues. And yet, without sacrificing the truthfulness of his own art, he cannot go so deep here as the novelist.

Through his a.n.a.lysis of his characters, the novelist must, however, construct them; otherwise he is a psychologist, not an artist. A synthetic vision of personality must supervene upon the dissection, and the emotional interest in character and action must subsist alongside of the intellectual interest. He must not let us lose the vivid sense of a living presence. In order to keep this, he must continue to employ the direct method of description of person and action, and report of conversation. How far the a.n.a.lytic method may be carried and at the same time the sense of personality kept intact, may be inferred from the work of Henry James, who, nevertheless, seems at times to fail to bring the out-going threads of his thought back into the web which he is weaving.

Again, in order to reach the social, historical, and metaphysical background of life--the milieu, the method of thought is the only available one. For the milieu is not anything that can be seen or heard or touched; it does not manifest itself to perception, but has to be constructed by a process of inference and synthesis. Much of it, to be sure, can be divined from the acts and conversations, from the dress and manners of the characters, but there is always more that has to be directly expounded. The writer cannot rely upon the reader's perspicacity to make the right inferences, or upon his knowledge to supply sufficient data; nor can he make his characters tell all that he may want told about their past and the life of the world in which they live, and through the influence of which they have become what they are. The novelist must construct for the reader the _mise en scene_ of his story. Yet this must be held in complete subordination to the story. The intellectual background must lie behind, not athwart the story; it must be created for the sake of the story, not the story for its sake.

A philosophy of life, even, is the inevitable presupposition of every story. For no writer, no matter how direct and empirical he may be in his methods, can escape from looking at life through the gla.s.s of certain political, social, and religious ideas. He may have none of his own construction, yet he will unconsciously share those of his age. The prose literature of our own age, aside from some minor differences of technique, differs from that of the past chiefly through its more democratic and naturalistic views of life. And just as we rightly ask of the novelist that he enlighten us regarding the subtler causation of human action, so with equal right we may ask him to exhibit the relations of the persons and incidents which he describes to social organization, spiritual movements, and nature; for only so can they be seen in their complete reality. Yet right here lurks a danger threatening the enduring beauty of every story thus made complete. For the social and cosmic background of life, as we have observed, can be constructed only through thought, and thought, particularly regarding such matters, is peculiarly liable to error. The artist who goes very deep into this is sure to make mistakes. Even when he tries to use the latest sociological, economic, and political theories, he runs great risks; for these theories are always one-sided and subject to correction; they never prove themselves to be what the artist thinks and wants them to be--concrete views which he can apply with utter faith. How many stories of the century past have been marred by the author's too ready application of Darwinism to social life! When we can separate the story from its intellectual background, the inadequacy of the latter matters little; for we can apply metaphysical and political criticism to the theory and enjoy the story aesthetically; but many of our writers come to life with preconceived ideas deeply affecting their delineation of it. The picture no longer seems true because we feel that a false theory has prevented the artist from viewing life concretely and clearly. We could, for example, accept as natural and inevitable the ending of _Tess of the D'Urbervilles_, if Hardy had not presented it as an ill.u.s.tration of the cruel sport of the G.o.ds. As it stands with the author's commentary, we suspect that the girl's fate might have been different,--that perhaps he gave it this turn in order to prove his theory of life.

This fault is especially flagrant in the theory-ridden fiction of to-day. Determination through the past is overemphasized as against the influence of present, novel factors in a growing experience; heredity is given undue weight as against the inborn originality of personality and the uniqueness acquired through unique experiences; the influence of sensual motives is stressed at the expense of the moral; and so on through all the other abstractions and insufficiencies of "scientific" novel writing. The writer may well profit by everything he can learn from science; but he should not let his knowledge prevent him from seeing life concretely and as a whole. The literary man's science and philosophy are bound to be condemned by the expert, but his concrete delineations of life based on direct observation and vivid sympathy and imagination are impeccable. His theories may be false, but these will always be true. Nothing can take their place in fiction.

It is they which give enduring value to such tales as _Morte d'Arthur_, despite all the crudity of the intellectual background.

Reflections upon life may become matter for literature in the essay, quite apart from any story. But the essay, like the story, unless it is to compete at a disadvantage with science and philosophy, must rely upon first-hand personal acquaintance with life, and artistic expression. The more abstract and theoretical it becomes, the more precarious its worth. I do not mean that the essayist may not generalize, but his generalizations should be limited to the scope of his experience of life. I do not mean that he should not philosophize, but his philosophy should be, like Goethe's or Emerson's, an expression of intuition and faith. Properly, the literary essay is a distinct artistic genre--the expression of a concrete _thinking_ personality, and its value consists in the living wisdom it contains. Such essays as those of a Montaigne or a La Rochefoucauld make excellent materials for the social sciences, and can never be displaced by them as sources of knowledge of life.

Considerations similar to those which we have adduced regarding the implied philosophy of a story apply to its moral purpose. We cannot demand of the writer that he have no moral purpose or that he leave morality out of his story. For, since the artist is also a man, he cannot rid himself of an ethical interest in human problems or with good conscience fail to use his art to help toward their solution. His observations of moral experience will inevitably result in beliefs about it, and these will reveal themselves in his work. Yet we should demand that his view of what life ought to be shall not falsify his representation of life as it is. Just as soon as the moral of a tale obtrudes, we begin to suspect that the tale is false. We have such suspicions about Bourget, for example, because, as in _Une Divorce_, we are never left in doubt from the beginning as to the conventions he is advocating. And along with the feeling for the reality of the story goes the feeling for the validity of the moral; they stand and fall together.

A story's moral, like life's moral, is convincing in proportion as it is an inference from the facts. The novelist, fearing that we may not have the wits to discern it, is justified in drawing this inference himself; yet it must show itself to be strictly an inference from the story--the story must not seem to have been constructed to prove it. "_Die Weltgeschichte ist das Weltgericht,_" wrote Schiller; even so, the delineation of life is the criticism of life. To show the scope of disillusion, monotony, repression--life's generous impulses narrowed and made timid by the social, economic, and political machine--would be a criticism of our modern world; there would be no need of moralizing.

This the Russian novelists seem to have understood; they judged Russian life by describing it.

The man who writes literature as a means for promulgating political or moral ideas is either a conservative who desires to return to the conventions of the past, or else a radical who seeks the establishment of a new mode of life. The method employed by the former usually consists in exposing the restlessness and unhappiness of people who live in accordance with "advanced" ideas in comparison with the contentment of those who follow the older traditions. Such stories are, however, inconclusive, because they imply the false sociological thesis that the remedy for present ills is a return to the customs of the past. Happiness can indeed exist only in a stable society; but each age must create its own order to suit its changing needs; it cannot, if it would, go back to the old. These stories, therefore, although they often contain truthful and valuable pictures of the ills of contemporary life, and are useful in helping to conserve what is good in the spirit of the past, are nevertheless bound to be futile in their main endeavor.

The method of the radical usually consists of two parts: one of criticism, designed to show the misery due to existing laws and inst.i.tutions; another of construction, the disclosure of a new and better system. But here, too, the constructive part of the story is likely to be weak. For whether the writer sets forth his program by putting it into the mouth of one of his characters or appends it as a commentary to his story, the practicability of his scheme is always open to question. It is only through trial that any scheme can be shown to be workable. There is, however, a new method that deserves better the name of "experimental romance" than Zola's own works. It consists in portraying people living in accordance with new sentiments and ideals, or even under new inst.i.tutions imaginatively constructed. Yet this method also has its weakness, for it is difficult to make people believe in the reality of a life that has not been actually lived.

Still, this difficulty is not fatal; for experiments in living are constantly being made all around us, which the discerning novelist needs only to observe and report. He can show the success of these or how, if they fail, their failure is due, not to anything inherently vicious, but simply to adverse law and opinion. Life is full of such stories waiting for some novelist who is not too timid to tell them.

We are thus brought round again to the thesis that the enduringly valuable elements of every story are its concrete creations of life.

In the end, the story teller's fame will rest upon his power to create and reveal character and upon his sense for fate. There is just one thing that should be added to this--a rich emotional att.i.tude toward life. It is the greater wealth of this that makes a novelist like Thackeray or Anatole France superior to one like Balzac. The personality that tells the story is as much a part of the total work as the characters and events portrayed, and must be taken into account in any final judgment of the whole. Without the author's vivid and rich partic.i.p.ation, we who read can never be fully engaged, and we shall find more of life in the story, the more there is of him in it.

CHAPTER XI

THE DOMINION OF ART OVER NATURE: PAINTING

In literature, as we observed in our last two chapters, nature does not find aesthetic expression on its own account. In the lyric, nature appears only as the reflection of personal moods and thoughts, in the drama and novel and epic only as the theater of human action or the determiner of human fate. In painting and sculpture, on the other hand, the expression of nature is the primary aim. Of course, in so far as this expression is aesthetic, it is an expression not of nature alone, but of our responses as well; but nature is the starting point, not emotion as in lyric poetry, nor the effect upon destiny as in the epic.

Because they are expressions of nature, and because the copying of the human body, of trees, clouds, and the like is an indispensable part of their practice, painting and sculpture have seemed to give support to the theory of art as imitation. Yet, although the activity of imitation is a means to the creation of picture and statue, the mere fact of being a copy is not the purpose of the completed work nor the ground of our pleasure in it. Not its relation to anything outside itself, no matter how important for its making, but its own intrinsic qualities const.i.tute its aesthetic worth.

This was true of the earliest efforts in these arts. The primitive artist copied not for the sake of copying, but because he ascribed a magical power to images. In the image he believed he somehow possessed the object itself, and so could control it; to the image, therefore, was transferred all the value and potence of the object. The object represented was deeply significant; it was perhaps the animal upon which the tribe depended for its food, its totem or guardian divinity; or else, as among the Egyptians, it was the man himself, of whom the image was meant to be an enduring habitation for the soul. If primitive men had copied indifferent objects, then we might infer that the mere making of an image was the end in view; but this they did not do, and it has never been the practice of any vigorous group of artists. Only when the means are valued instead of the end--technique in place of beauty--does this occur. Through such a mistaking of aims, new instruments of expression may be discovered, useful for a future genius, but no genuine art is produced. The genuine artist copies, not for the sake of copying, but in order to create a work of independent beauty.

This same transference of value to the image, with the consequent freeing of the image from the model, can be observed even in commemorative art. A king desires, perhaps, to perpetuate his memory; how better than through some enduring likeness in stone or paint? While he is alive and after his death this image will remind his subjects of him and his valorous deeds. The relation to the model seems to be fundamental; but in proportion to the success of the artist in making a likeness, the stone or paint will be made to seem all alive, and for those who cannot come into direct relations with the monarch, he will be effectively present in the statue or picture, even when, through death, he is removed from all social and practical relations. Who does not feel that Philip the Fourth is present on the Velasquez canvas; where else could one find him so alive? If the work is artistic, the spectator's interest will center in feeling the life in the color and line or sculptured form; that it happens to be an imitation of something else will become of secondary importance. This is clearest when the name of the subject is not known; then surely it is the life before us that can alone concern us. Any feeble copy would serve as a reminder, but a living drawing or statue brings the man or woman into our presence. The aesthetic interest in the work as living supervenes upon the interest in it as a mere reminder of life.

This freedom from the model and attainment of intrinsic worth in the work of art itself is furthered through the realization of beauty in the medium of expression. The colors, lines, and shapes which the artist uses have a direct appeal to the eye and through the eye to feeling; hence arise preferences for the most agreeable and expressive.

The artist discovered that he could express his emotion not only through representing its object, but through the very colors or lines or shapes used in the delineation. These effects, found by chance perhaps in the first instance, would later be striven for consciously. In this way, through some grace of line, or symmetry of form, or harmony of color, the statue or picture would acquire a power to please quite independent of any ulterior use or purpose; once more, it would become alive and of value on its own account.

We shall begin our study of the representative arts with drawing and painting--representation in two dimensions--not because they preceded sculpture historically, but because, being more complex arts, a solution of the problems which they raise makes a subsequent survey of the similar problems of the simpler art relatively easy.

The media of pictorial expression are color and line, and expression is attained through them in a twofold fashion. In a picture, every element of color or line is expressive directly, just as color and line, of some vague feeling or mood, and, in addition, chiefly through its resemblance, represents some action or object. The former kind of expression is indispensable. No matter how realistic the imitation, unless the picture thrill like music, through its mere colors or lines, it is aesthetically relatively ineffective. It is not sufficient that the picture move us through the vicarious presence on the canvas of a moving object; it must stir us in a more immediate fashion through the direct appeal of sense. For example, a picture which presents us with a semblance of the sea will hold us through the power which the sea has over us; but it will not hold us so fast as a picture of the same subject which, in addition, grips us through its greens and blues and wavy lines. The one sways us only through the imagination, the other through our senses as well.

Sensitiveness to color as such, so self-evident to one who possesses it, seems to be wanting, except in rudimentary fashion, in a great many people. They are probably few, however, who do not feel some stirrings when they look through the stained gla.s.s of a cathedral window or upon the red of Venetian gla.s.s, or who are entirely indifferent to the color of silk. The reason for emotional color-blindness is probably not a native incapacity to be affected, but rather a diversion of attention; color has come to be only a sign for the recognition and subsequent use of things, a signal for a practical or intellectual reaction. In our haste to recognize and use we fail to see, and give ourselves no time to be moved by mere seeing.

But when, as in art, contemplation, the filling of the mind with the object, is the aim, the power to move of the sensuous surface of things may come again into its rights.

The emotional response to color, vague and abstract and objectless, is, like music, incapable of adequate expression in words, and for the same reason. Words are capable of expressing only the larger and fairly well-defined emotions; such subtle shadings and complex mixtures of feeling as are conveyed by color and sound are mostly beyond their ken. Colors make us feel and dream as music does in the same incommunicable fashion. Or rather the only possibility of communicating them is through the color schemes arousing them. And for one who appreciates color this is sufficient; he can point to the colors and say--that is what I feel. To render his feeling also in words would be a superfluous business, supposing they could be adequate to express it; or, if they were adequate, that would make expression through color superfluous. The value of any medium consists in its power to express what none other can. Nevertheless, it is possible to find rough verbal equivalents for the simpler colors. Thus every one would probably agree with Lipps and call a pure yellow happy, a deep blue quiet and earnest, red pa.s.sionate, violet wistful; would perhaps feel that orange partakes at once of the happiness of yellow and the pa.s.sion of red, while green partakes of the happiness of yellow and the quiet of blue; and in general that the brighter and warmer tones are joyful and exciting, the darker and colder, more inward and restful.

To explain the expressiveness of color sensations is as difficult as to account for the parallel phenomenon in sounds. Here as there resort is had to the principle of a.s.sociation. Colors get, it is thought, their value for feeling either through some connection with emotionally toned objects, like vegetation, light, the sky, blood, darkness, and fire, or else through some relation to emotional situations, like mourning or danger, which they have come to symbolize. And there is little doubt that such a.s.sociations play a part in determining the emotional meaning of colors--the reticence and distance of blue, the happiness of yellow, for example, are partly explained through the fact that blue is the color of the sky, yellow the color of sunlight; the meaning of black is due, partly at any rate, to a.s.sociation with mourning. Yet neither of these types of a.s.sociation seems sufficient to explain the full emotional meaning of colors. The conventional meanings of colors seem rather themselves to need explanation than to serve as explanations--why is red the sign of danger, purple royal, white a symbol of purity, black a symbol of mourning? Is it not because these colors had some native, original expressiveness which fashion and habit have only made more definite and turned to special uses? And if we can explain the reticence of blue through a.s.sociation with the sky, can we thus explain its quietness? Can the warmth of fire and the excitement of blood explain quite all the depth of pa.s.sionate feeling in red? The factors enumerated play a part in the complex effect, but there seem to be elements still unaccounted for.

In order to explain the total phenomenon we must admit, as in the case of tones, some direct effect of the sensory light stimulus upon the feelings. Rays of light affect not only the sensory apparatus, causing sensations of color; their influence is prolonged into the motor channels, causing a total att.i.tude of the organism, the correlate of a feeling. It would be strange if any sensory stimulus were entirely cut off by itself and did not find its way into the motor stream. But these overflows are too diffuse to be noticed in ordinary experience; they are obscured through a.s.sociation or are not given time to rise to the level of clear consciousness, because we are preoccupied with the practical or cognitive significance of the colors; only in the quiet and isolation of contemplation can they come into the focus. Of course the student of the evolution of mind will want to go behind these color emotions and inquire why a given color is connected with a given reaction. He may even want to connect them with instinctive responses of primitive men. But here we can only speculate; we cannot know.

The problem is further complicated through the fact that private color- a.s.sociations are formed obscuring the aesthetic meanings, which can be rediscovered only through the elimination of the former. Color preferences are often determined in this way; yet sometimes they spring from another and more radical source--an affinity between personal temperament and the feeling tone of the preferred color. A consistent choice of blues and grays indicates a specific kind of man or woman, very different from the chooser of yellows and reds.

Although single color tones are expressive, they seldom exist alone in works of art. Significant expression requires variety. The invention of original and expressive color combinations is a rare gift of genius.

Rough rules of color combination have been devised from the practice of artists and from experiment, the following of which will enable one to produce faultless patterns, but without genius will never enable one to create a new expression. Color combinations are either harmonious or balanced, the former produced by colors or tones of colors very close to one another, the latter by the contrasting or widely sundered.

In the one case, we get the quiet commingling of feelings akin to each other; in the other, the lively tension of feelings opposed. Compare, for example, the effect of a Whistler nocturne with a Monet landscape.

The colors that do not go well together are such as are not close enough for union nor far enough apart for contrast. They are like personalities not sufficiently at one to lose themselves in each other, yet not sufficiently unlike to be mutually stimulating and enlarging, between whom there can be only a fruitless rivalry turning into hate.

Such are certain purples and reds, certain greens and blues. Yet, through proper mediation, any two colors can be brought into a composition. All colors are brought together in nature through the sunlight, and in painting or weaving by giving to rival colors the same sheen or brightness. Or again, the union may be effected by combining the two with a third which is in a relation of balance or harmony with each, as in the favorite scheme of blue, red, and green.

Despite their ability to express, colors cannot stand alone; they must be the colors of something, they must make line or shape. Lines, on the other hand, seem to be independent of color, as in drawings and etchings; yet there is really some color even there--black and white and tones of gray. That color and line are independent of one another in beauty, is, however, shown by works, such as Millet's, which are good in line but poor in color. Lines have, as we have already seen, the same duality of function as colors: they express feeling directly through their character as mere lines and they represent objects by suggesting them through resemblance.

There is, in fact, for those who can feel it, a life in lines of the same abstract and objectless sort as exists in colors and tones. Lines give rise to motor impulses and make one feel and dream, as music does.

There are many who are cold to this effect; yet few can fail to get something of the vibration or mood of the lines of a Greek vase painting, a Botticelli canvas, or a Rembrandt etching. The life of lines is more allied to that of tones than of colors because it possesses a dynamic movement quality which is absent from the latter.

This life is, in fact, twofold: on the one hand it is a career, with a beginning, middle, and end, something to be willed or enacted; on the other hand it is a temperament or character, a property of the line as a whole, to be felt. These two aspects of aesthetic lines are closely related; they stand to one another much as the temperament or character of a man stands to his life history, of which it is at once the cause and the result. Just as we get a total impression of a man's nature by following the story of his life, so we get the temperamental quality of lines by following them with the eye; and just as all of our knowledge of a man's acts enters into our intuition of his nature, so we discover the character of the total line by a synthesis of its successive elements.

It is as difficult, more difficult, perhaps, to put into words the temperamental quality of lines as to do the parallel thing with colors.

Lines are infinite in their possible variations, and the fine shades of feeling which they may express exceed the number of words in the emotional vocabulary of any language. Moreover, in any drawing, the character of each line is partly determined through the context of other lines; you cannot take it abstractly with entire truth. It is, however, possible to find verbal equivalents for the character of the main types of lines. Horizontal lines convey a feeling of repose, of quiet, as in the wall-paintings of Puvis de Chavannes; vertical lines, of solemnity, dignity, aspiration, as in so much of the work of Boecklin; crooked lines of conflict and activity, as in the woodcuts of Durer; while curved lines have always been recognized as soft and voluptuous and tender, as in Correggio and Renoir. The supposition that the curved line is the sole "line of beauty" is the result of a narrow and effeminate idea of the aesthetic; yet it must be admitted that this form, since it permits of the greatest amount of variation, has the highest power of expression; but in many of its more complex varieties it loses much of its soft feminine quality, and takes on some of the strength of the other forms.

The expressiveness of lines is determined by several--at least three-- factors. In the first place, the perception of lines is an active process. In order to get a line we have to follow it with the eye; and if we do not now follow it with our fingers, we at least followed similar lines thus in the past. Now this process of the perception of a line requires of us an energy of attention to the successive elements of the line as we pa.s.s over them and a further expenditure of energy in remembering and synthesizing them into a whole. This energy, since it is evoked by the line and is not connected with any definite inner striving of the self, is felt by us to belong to the line, to be an element in its life, as clearly its own as its shape. For example, a line with many sudden turns or changes of direction is an energetic and exciting line because it demands in perception a constant and difficult and shifting attention; a straight line, on the contrary, because simple and unvarying in its demands upon the attention, is monotonous and reposeful; while the curved line, with its lawful and continuous changes, at once stimulating yet never distracting attention, possesses the character of progressive and happy action. This, the primary source of the vital interpretation of lines is supplemented by elements derived from a.s.sociation. Lines suggest to us the movements of our bodies along paths of similar form, and we interpret them according to the feeling of these movements; in the imagination, we may seem to move along the very lines themselves as paths. Every skater or runner knows the difficulty of moving along a path full of sudden turns and angles, a difficulty which, if he is in good trim, may nevertheless afford him pleasure in the overcoming; the delightful and various ease of moving along curved lines; the monotony of a long, straight path, but the quick triumph of going right to the end along a short and terminal line of this character. But lines suggest to us not only the movements, but also the att.i.tudes of our bodies. They may be straight and rising,--rigid or dignified or joyously expanding; they may be horizontal and lie down and rest; they may be falling and sorrowful; or the shapes whose outlines they form may be heavy or light, delicate or ungainly or graceful, as bodies are. Finally, the interpretation of lines may be further enriched as follows: The sight of a line suggests the drawing of it, the sweep of the brush that made it; we ourselves, in the imagination once more, may re-create the line after the artist, and feel, just as he must have felt, the mastery, ease, vigor, or delicacy of the execution into the line itself. Few can fail to get this effect from the paintings of Franz Hals, for example, where the abounding energy of the artist is apparent in each stroke of the brush. Artists feel this life in execution most strongly; yet, since almost every one has had some practice in drawing lines, it is potentially a universal quality in a painting.

Lines may be unified according to the three modes of harmony, balance, and evolution. The repet.i.tion of the same kind of line confers a harmonious unification upon a drawing, as in Tintoretto's "Bacchus and Ariadne," where the circle is to be found repeated in the crown and ring, in the heads of the three figures, in the b.r.e.a.s.t.s of Ariadne.

Similar to this sameness of form is sameness of direction or parallelism of lines. Another kind of harmonious unification of lines is continuity, where out of different lines or shapes a single line is made. The cla.s.sical geometrical forms of composition, as the circular or pyramidal, are good examples of this. The "Odalisque" of Ingres, where all the lines of the body const.i.tute a single line, is a notable case.

What Ruskin has called "the approach, intersection, interweaving of lines, like the sea waves on the sh.o.r.e,"--the conspiracy of all the lines in a drawing to form one single network, of which ill.u.s.trations could be found in the work of every draftsman, is a kind of harmony of line. Symmetrically disposed shapes, and lines whose directions are opposed, have the balanced form of unity. Here, from a given point as center, the attention is drawn in contrary yet equal ways. Examples of this type of composition are abundant among the Old Masters; as a rigid form it is, however, disappearing. That the dramatic type of unity is to be found in lines will be confirmed by every one who has observed the movement, the career of lines. Whenever shapes are so disposed that they form a line leading up to a given shape, wherever, again, lines converge to a single point, there is a clear case of evolution; we begin by attending to the line at a certain point, proceed in a certain direction, then reach a terminal point, the goal of the process. In Leonardo's "Last Supper," the convergence of the perspective lines and the lines formed by the groups of Apostles is a case of evolution. The different types of unification are, of course, not exclusive. In the painting just referred to, all three are present: Christ and the Apostles are arranged along a single line, the two ends of which, despite their symmetrical and balanced disposition, converge to one central point, the Christ. Every pyramidal form of composition is a combination of balance between the elements at the bases of the triangle, convergence towards the apex, and harmony through the partic.i.p.ation of the three elements in a single form. One of the most interesting and complex types of organization of lines is rhythm--the balanced, harmonious movement of lines. A line is rhythmical when there is a balanced alternation of direction in its movement, a turning now to the right and now to the left, or vice versa; proportion in the length of the segments made by the turns; and general direction--a tending somewhere.

As is a.s.sumed in the preceding paragraph, the elements of lines may be shapes or ma.s.ses, as well as points. That is, not only do lines made up of points form shapes, but shapes in their turn, when arranged on a surface, necessarily make lines. Such lines are, as a rule, not continuous; yet since the eye takes the shapes successively and in a given direction, they are nevertheless true lines and possess the qualities of ordinary simple lines. The arrangement of ma.s.ses in an undulating line, say in a landscape painting, has essentially the same value for feeling as a similar continuous line; compare this with a horizontal arrangement of ma.s.ses, which has all the quiet and repose of a simple horizontal line.

Colors and lines, relying on the direct expressiveness which we have been studying, may stand by themselves, as in an oriental rug; yet in painting they have another function: to represent. And even in the purely ornamental use of color and line, the tendency towards representation is apparent everywhere; either the lines are derivatives of schematized pictures of men and plants and animals, or else such objects are introduced as motives without disguise. In painting, therefore, the color red has value not only as so much red, but as standing for the red of a girl's lips or cheeks; and that curved line is of significance, not as mere line alone, but as the curve of her limbs. In this way the native value of the sense symbols becomes suffused and enriched with the values of the things they represent.

The two functions of color and of line should never be indifferent to each other; representation should not become a mere excuse for decoration, the objects represented having no value in themselves; nor should color and line be used as mere signs of interesting objects, without reference to their intrinsic value. On the contrary, the two functions should play into each other's hands. If, for example, the human body is represented, the colors and lines employed should be so disposed that they decorate the surface of the picture and hold us there through their sheer rhythm and quality; yet, at the same time, and through their very ornamental power, they should make us feel the more keenly the values of the object they represent. Between the immediate values of the colors and lines there should exist unity: stimulating colors should go with stimulating lines, quiet colors with quiet lines; and the resulting feeling tone of the medium should be in harmony with the feeling of the objects represented; the one should give the other over again, and so each enforce the other.

Since it is not the purpose of any art to represent mere things, but to express concrete "states of the soul," the center of which is always some feeling, exact fidelity in the representation of objects is not necessary for good painting or drawing. Only so much of things needs to be represented as is necessary to give back the life of them.

Necessary above all is the object as a whole, for to this our feelings are attached; now this can usually be far better represented through an impressionistic sketch, which gives only the significant features, than by a painstaking and detailed drawing. Since, furthermore, the life of things can be conveyed through color and line as such, a certain departure from realism is legitimate for this end. Without some freedom from the exact truth of the colors and lines of things, the artist is unable to choose and compose them for expressive purposes; when exactly like the objects which they represent, they tend to lose all expressive power of their own, becoming mere signs or equivalents of things. A certain amount of variation from the normal may be necessary in order that the sense symbols shall call attention to themselves, in order that we be prevented, as we are not in the ordinary observation of nature, from looking through them to the things which they mean.

Whenever, moreover, the artist wishes to render a unique reaction to a scene, he can do so only through a courageous use of the subtle language of color and line, which may require a distortion of the "real" local qualities of things; for, if he makes a plain, realistic copy of the scene itself, he can evoke, and so express, only the normal emotional responses to it.

When such departures from the truth of things are properly motivated, no one can be offended by them, any more than when the brilliant hues of nature appear black and white in a charcoal drawing. The amount of realism in any work of art is largely a matter of tacit convention.

An artist may, if he wishes, use color with no pretense at giving back the real colors of objects, but for purely expressive purposes alone, relying on line for purposes of representation. This is often done in j.a.panese prints. All that is necessary is that we should understand what the artist is doing and find what he presents to us real and alive. On the other hand, an expressive use of color and line leading to a distortion of objects out of all possibility of recognition, or even a use which makes them seem unreal and awry, is without excuse.

For since colors and lines are employed to bring things before the imagination, they should be made to serve this purpose successfully; the value which belongs to the things should have a chance to appear; but this can happen only if they seem to be actually present before us. Painting is not a mere music of color and line expressive of abstract and objectless emotions alone, but a poetry, which, through the picturing of objects to which emotions are attached, renders the latter concrete and definite. Not mere feeling, such as a color or a line by itself can convey, but feeling in the presence of nature, which can be expressed only when color and line are made into a recognizable image of nature, is the substance of painting. One cannot express the feeling of the weight and bulk of objects, of their distribution in three dimensions, or the value of their shadows or atmospheric enveloping, without the representation of weight and bulk and shadow and atmosphere and perspective. Every increase in the power to represent nature, every advance in the mastery of the object, adds a new power over the expression of feeling, which varies with the object. The realist is, therefore, right in his demand that nature itself be painted; only he should remember that the nature which presents itself in art is never the naked object, but veiled in feeling; and, as so veiled, may sometimes be seen pretty much as it really is; then again with parts concealed, and sometimes even transformed. Both a realism that tries to unite fidelity to the full qualities of the object with musical expression in the medium, and so to render the more typical responses to nature, which depend, for the most part, on the object itself, and a symbolism or expressionism that sacrifices fidelity for the expression, through the mere medium, of more personal responses, are in their rights. Only the limits of both tendencies are illegitimate--the use of color and line to produce mere images of things on the one hand, or purely musical effects on the other.

The subject matter or content of painting is determined by its language, color, and line. These, as we have seen, by an imitation more or less exact, represent nature, the world of concrete things as directly presented to us in vision, colored and shapely. The inner world is expressed only so far as it is revealed in the gestures and att.i.tudes of the bodies of men or so far as it is a mood attached to things and their colors and shapes. Now s.p.a.ce is the universal container in which all elements of the visible world are disposed. Every painting, therefore, should include a representation of s.p.a.ce; it should never represent things as if they stood alone without environment or relation.

Even in the portrait of a single individual some relation to s.p.a.ce should be indicated; this is accomplished by the background, in which the figures should be made to lie, and to which they should seem to belong. In front, the s.p.a.ce of a picture is limited by the plane of the surface on which it is painted; everything should appear to belong in the s.p.a.ce back of this; nothing should seem to come forward out towards the spectator. But behind this, backwards, the s.p.a.ce represented is unlimited, and its infinite depths may well be indicated by the convergence of perspective lines and the gradual fading of the outlines and colors of objects.
