The Principles of Aesthetics Part 3

Or who that has lived constantly with a sick person has not observed how, looking on the face of pain, inevitably the mere comment, "he is in distress," comes to supplant the liveliest sympathetic thrill? There are many reasons for this. The idea or judgment is a less taxing thing than an emotion, and so is subst.i.tuted for it in the mind, which everywhere seeks economy of effort. The idea is also more efficient from a practical point of view, because it leads directly to action and does not divert and waste energy in diffused and useless movements.

The physician simply recognizes the states of mind of his patients, he does not sympathize with them. Finally our own reactions to an objectified emotion may interfere with the emotion. If, for example, we see an angry man, our own fear of him may entirely supplant our sympathetic feeling of his anger. In general, in our dealings with our fellow men, we are too busy with our att.i.tudes and plans with reference to them, and too much concerned with economizing our emotional energy, to get a sympathetic intuition of their inner life, and so are content with an intellectual recognition of it. Now this habit of subst.i.tuting the more rapid and economical process of judgment for the longer and more taxing one of sympathy, is carried over into the world of art.

Nevertheless, the world of art is a region especially fitted for _einfuehlung._ For there the need for quick action, which in life tends to syncopate emotion, does not exist. The characteristic att.i.tude of art is leisurely absorption in an object, giving time for all the possibilities of feeling or other experience to develop. Moreover, in art there is not the same saving need for the subst.i.tution of idea for feeling as in real life. For in art, feeling is not so strong as in life; even when the artist expresses his own personal experience, he lightens its emotional burden through expression, and we, when we make his experience ours, find a similar relief. The emotion is genuine, only weakened in intensity. In other cases, where the artist constructs a world of fict.i.tious characters and events, our knowledge that they are not real suffices to diminish the intensity of the emotions aroused.

For emotions have the practical function of inciting to action, and when action is impossible, as in the purely ideal world of the artist, they cannot keep their natural intensity. We cannot feel so strongly over the mere idea of an event as over a real event. Were it otherwise, who could stand the strain of _Hamlet_ or _Oth.e.l.lo_?

Throughout this discussion of the elements of the experience of art, I have used the terms emotion and feeling with an inclusive meaning, to cover impulses as well as feelings in the narrower sense. For in the aesthetic experience, there are impulses--impulses to move when action is represented in picture and statue, impulses to act, as when, in watching a play, we put ourselves in the place of the persons. But such impulses are always checked through the realization that they come from sources unrelated to our purposes, and fail to get the reenforcement or consent of the total self necessary to action. In reading or singing the "Ma.r.s.eillaise," to cite an example from poetry, I experience all kinds of impulses--to shoulder a musket, to march, to kill--but no one of them is carried out. Now an inhibited impulse is scarcely distinguishable from an emotion. With few exceptions, the impulses in art do not issue in resolves, decisions, determinations to act; or, if they do, the determinations refer to acts to be executed in the future, in an experience distinct and remote from the sthetic--the "Ma.r.s.eillaise" has doubtless produced such resolutions in the minds of Frenchmen; and there is much art that is productive in that way, providing the "birth in beauty" of which Plato wrote.

[Footnote: In the _Symposium_.] In art, impulses result in immediate action only when action is itself the medium of expression, as in the dance, where impulses to movement pa.s.s over into motion. Of course such actions still remain aesthetic since they serve no practical end and are valued for themselves.

If the question were raised, which is more fundamental in the aesthetic experience, idea or emotion? the answer would have to be, emotion. For there exists at least one great art where no explicit ideas are present, music, whereas art without emotion does not exist. Take away the emotional content from expression and you get either a mere play of sensations, like fireworks, or else pseudo-science, like the modern naturalistic play. However, the supreme importance of the idea in art cannot be denied. Every complex work of art, save music, is an expression of ideas as well as of feelings, and even in music there exists the tendency for feeling to seek definition in ideas--do we not say a musical idea? And do we not find the masters of so abstract an art as ornament employing their materials to represent symbolic conceptions? I wish to call the attention of the reader to certain very general considerations touching the nature and function of ideas in the aesthetic experience, leaving the study of the concrete problems to the more special chapters.

First, the relation of the idea to the sense medium of the expression.

Here, I think, we find something comparable to the process of _einfuehlung_. For in art, ideas, like feelings, are objectified in sensation. Only sensations are given; out of the mind come ideas through which the former are interpreted and made into the semblance of things. Consider, for example, Rembrandt's "Night-Watch." A festal mood is there in the golds and reds, and gloom in the blacks; but there also are the men and drums and arms. If we wished to push the a.n.a.logy with _einfuehlung_, we might coin a corresponding term--_einmeinung_, "inmeaning." In all the representative arts, this is a process of equal importance with infeeling; for the artist strives just as much to realize his ideas of objects in the sense material of his art as to put his moods there.

When, moreover, we consider that the expression of the more complex and definite emotions is dependent upon the expression of ideas of nature and human life, we see that the process is really a single one.

Feeling is a function of ideas; if, then, we demand sincerity in the one, we must equally demand conviction in the other. The poet could not convey to us his pleasure at the sight of nature or his awe of death unless he could somehow bring us into their presence. The painter could not express the moods of sunlight or of shadow until he had invented a technique for their representation. Clear and confident seeing is a condition of feeling. Hence every advance in the imitation of nature is an advance in the power of expression. The demand for fidelity of representation, for "truth to nature," so insistently made by the common man in his criticism of art, is justified even from the point of view of expressionism.

Yet this fidelity of representation does not involve exact reproduction of nature. The limitations of the media of the arts definitely exclude this. No painter can reproduce on a canvas the infinite detail of any object or exactly imitate its colors and lines. In the single matter of brightness, for example, his medium is hopelessly inadequate; even the light of the moon is beyond his power, not to speak of the light of the sun; he has to subst.i.tute a relative for an absolute scale of values. The sculptor cannot reproduce the color or hair of the human body. However, this failure exactly to imitate nature does not prevent the artist from suggesting to us ideas of the objects in which he is interested. If the outline of the marble be that of a man, we get the idea of a man; if the color and shape be that of a tree, we get the idea of a tree. Our acceptance of these ideas is, of course, only partial; for we are equally susceptible to the negative suggestions of the whiteness of the marble and the smallness of the outline of the tree. Every work of art represents a sort of compromise between reality and unreality, belief and disbelief.

Nevertheless, despite this compromise, the purpose of art is uncompromisingly attained. For art does not seek to give us nature over again, but to express its feeling tones, and these are conveyed when we get an idea of the corresponding object, even if that idea is inadequate from a strictly scientific point of view. We do not react emotionally to the infinite detail of any object, but only to its presence as a whole and to certain salient features. The artist succeeds when he constructs a humanized image of the object--one which arouses and becomes a center for feeling. This image, when made of a few elements, may be far more telling than a much more accurate copy; for there is no diffusion of interest to irrelevant aspects. How effective a medium for expression are the few and simple lines of Beardsley's draftsmanship! The amount of detail necessary to convey an emotionally effective idea is relative to the technique of the different arts and varies also with the suggestibility and discrimination of the observer.

Here no a priori principles can be laid down for what only the experimental practice of the artist can determine.

Moreover, the negative suggestions of a work of art, although they are effective in preventing entire belief in the reality of the idea expressed, do not hinder the communication and appreciation of the attached feelings. Just so long as the belief att.i.tude is not wholly extinguished, this is the case; and the skillful artist takes care of that. Of course, an att.i.tude of self-surrender, of willingness to accept suggestions, has to be present and we cooperate with the artist in creating it. Aesthetic belief implies sufficient abandon that we may react emotionally to a suggestion, but not enough that we may react practically. We let the idea tell upon our feelings; we do not let it incite us to action. The aesthetic plausibility of an idea depends largely upon its initial plausibility with the artist. There is nothing more contagious than belief. To utter things with an accent of conviction is half the battle in getting oneself believed. If the artist pretends to believe something and expresses himself with an air of a.s.surance, we accept it, no matter how preposterous it may be from the practical or scientific point of view. Think of Rabelais!

A work of art is a logical system. It presupposes certain a.s.sumptions, postulates, conventions, which we must accept if we are to live in its world. Now, in order that we may accept them, the artist must first have vividly accepted them himself. Only if they have become a very part of him, can they become at all valid for us. The failure of cla.s.sicistic art in a non-cla.s.sical age, of "Pre-Raphaelitism" after Raphael, is a failure in this--the artist has never lived even imaginatively in the world he depicts. His belief is an artifice and a sham, and he cannot impose upon us with his pretense. But once we have accepted the artist's postulates, then we are prepared to follow him in his conclusions. In the Homeric world, we shall not balk at the intercourse between G.o.ds and men; in mediaeval painting and drama, we shall accept miracle; in _Alice in Wonderland_, we shall accept any dream-like enchantment. But we demand that the conclusions shall follow from the premises, that the whole be consistent. We cannot tolerate miracle in a realistic novel or drama, or glaring inaccuracy of fact in a historical novel, because they are in contradiction to the laws of reality tacitly a.s.sumed. The final demand which we make of any work, of art is that it live. What can be made to live for us may be beautiful to us. But nothing can draw our life into itself which has not drawn the artist's, or which is untrue to its own inner logic.

One of the most life-creating elements of a work of art is imagery.

Everywhere in art the tendency exists for ideas to be filled out, rendered concrete and vivid, through images. In looking at a painting of a summer landscape, for example, we not only recognize the colors as meaning sunlight, but actually experience them as warm; in looking at a statue we not only recognize its surface as that of the body of a woman, but we feel its softness and smoothness; which involves that the ideas of sunlight and a human body, employed in interpreting the sensations received from these works of art, are developed back into the original ma.s.s of images from which they were derived. However, although ideas are formed from images, they are not images,--as our ordinary employment of them in recognizing objects attests. We may and usually do, for example, recognize a mirror as smooth without experiencing it as smooth--the image equivalent of the idea remains latent. Our ordinary experience with objects is too hasty and too intent on practical ends for images to develop. On the other hand, the leisurely att.i.tude characteristic of the aesthetic experience is favorable to the recall of images; hence, just as in the aesthetic perception of objects we put our feelings into them, so equally we import into them the relevant images. The aesthetic reaction tends to be total. Our demand for feeling in art also requires the image; for feelings are more vividly attached to images than to abstract ideas.

It is a fact familiar in the experience of everybody that the strength of the emotional tone of an object is a function of the clearness of the image which we form of it on recall. We can preserve the feeling tone of a past event or an absent object only if we can keep a vivid image of it; as our image of it becomes vague, our interest in it dissipates. Everywhere in our experience the image mediates between feeling and idea. So in art. Images have no more an independent and self-sufficient status in art than sensations have; like the latter they are a means for the expression of feeling. In the painting of sunlight, for example, the images of warmth carry joyousness and a sense of ease; in the statue, the tactile images convey the emotional response to the represented object. In literature the expressiveness of images is perhaps even more impressive. Consider how longing is aroused by the tactile, gustatory, and thermal images in the oft-quoted lines of Keats:--

O, for a draught of vintage! that hath been Cool'd a long age in the deep-delved earth.

Examples might be multiplied indefinitely.

In literature alone of the arts, images from all departments of sense can be aroused. Visual images play a greater role there than in painting and sculpture, for the reason that, in the latter, visual sensations take their place--we do not image what we can see. In sculpture, the greater part of the imagery is of touch and motion--in the imagination, we feel the surfaces and move with the represented motions; the whiteness or blackness of the materials prevents the arousal of the image of the color of the body. In painting, besides the temperature images already mentioned, there are touch images--in still-life, for example, when silks and furs are represented; images of odors, in flower pieces; of motion, in pictures which depict motion, as in the racing horses of Degas; of taste, in pictures of wine and fruit. Of course the kind and amount of imagery depend upon the imaginal type to which the spectator belongs and the wealth of the imaginal furnishing of his mind. In any art, moreover, the chief and requisite thing is expression through the sense medium, which should never be obscured by expression through a.s.sociated images. It is not the primary business of a flower painter to arouse images of perfume, but to compose colors and lines; nor the function of the musician to arouse the visual images which accompany the musical experience of many people, but to compose sounds. In sculpture, on the other hand, images of touch and movement play an almost necessary part, for they are const.i.tuent elements in the representation of form and motion; yet it is not indispensable to the appreciation of sculpture that images of the sweet odor of the human body be awakened. The image is seldom the basis of aesthetic appreciation; it is more often its completion. But we shall go into these matters more in detail in our special chapters.

In the representative arts, particularly painting and sculpture, the a.s.sociated images are fused with the visual sensations which const.i.tute the medium. I see the softness and sweet-odorousness of the painted rose petal, just as I see the real rose soft and sweet; I see the surface of the statue firm and shapely, just as I see the human body so. This is because the ideas of the things represented in painting and sculpture seem to be actually present in the visual sensations which they interpret; the flower and the man seem to be there before me. In these arts, aesthetic perception is a fusion of image with sensation in much the way that normal perception is. In literature and music, on the other hand, the connection between the sense medium of the art and the a.s.sociated images is less close; and for the reason that the sounds are no part of the things which they bring before the mind. In looking at a picture of a rose, I see the red as an element of the rose represented; whereas, in reading about a rose, I only seem to hear a voice describing it. In the latter case, therefore, the olfactory and visual images have a certain remoteness and independence of the word-sounds; I do not actually see and smell them in the sounds.

However, in the case of familiar words with a strong emotional significance, the fusion of image with sound may be almost complete.

Who, for example, does not see a sweet and red image of a rose into the word-sounds when he reads:--

Oh, my love's like a red, red rose That's newly sprung in June.

Or, when Dante describes the _selva oscura_, who does not see the darkness in the word _oscura_? In all such cases a strong feeling tone binds together the word-sound with the image. This fusion is most striking in poetry because of the highly emotional material with which it works.

The ideas and images a.s.sociated with a work of art depend very largely on the education, experience, and idiosyncrasy of the spectator. The scholar, for example, will put tenfold more meaning into his reading of the _Divine Comedy_ than the untrained person. Or compare Pater's interpretation of the "Mona Lisa" with m.u.t.h.e.r's. Can we say that certain ideas and images belong properly to the work of art, while others do not? With regard to this, we can, I think, set up two criteria. First, the intention of the artist--whatever the artist meant his work to express: that it expresses. Yet, since this can never be certainly and completely discovered, there must always remain a large region of undetermined interpretation. Now for judging the relevancy of this penumbra of meaning and a.s.sociation the following test applies--does it bring us back to the sensuous medium of the work of art or lead us away?

Anything is legitimate which we actually put into the form of the work of art and keep there, while whatever merely hangs loose around it is illegitimate. For example, if while listening to music we give ourselves up to personal memories and fancies, we are almost sure to neglect the sounds and their structure; we cannot objectify the former in the latter; with the result that the composition is largely lost to us.

Naturally, no hard and fast lines can be drawn, especially in the case of works of vague import like music; yet we can use this criterion as a principle for regulating and inhibiting our a.s.sociations. It demands of us a wide-awake and receptive appreciation. The genuine meanings and a.s.sociations of a work of art are those which are the irresistible and necessary results of the sense stimuli working upon an attentive percipient; the rest are not only arbitrary, but injurious.

To this, some people would doubtless object on the ground that art was made for man and not man for art. The work of art, they would claim, should interpret the personal experience of the spectator; hence whatever he puts into it belongs there of right. There are, however, two considerations limiting the validity of this a.s.sertion. First, the work of art is primarily an expression of the artist's personality and, second, its purpose is to provide a common medium of expression for the experience of all men. If interpretation remains a purely individual affair, both its relation to the artist and the possibility of a common aesthetic experience through it are destroyed. For this reason we should, I believe, deliberately seek to make our appreciations historically sound and definite. And in the social and historical appreciation resulting, we shall find our own lives--not so different from the artist's and our fellows'--abundantly and sufficiently expressed.

CHAPTER V

THE a.n.a.lYSIS OF THE AESTHETIC EXPERIENCE: THE STRUCTURE OF THE EXPERIENCE

In our discussion of first principles, we set down a high degree of unity as one of the distinguishing characteristics of works of art.

In this we followed close upon ancient tradition; for the markedly structural character of beauty was noticed by the earliest observers.

Plato, the first philosopher of art, identified beauty with simplicity, harmony, and proportion, and Aristotle held the same view. They were so impressed with aesthetic unity that they compared it with the other most highly unified type of thing they knew, the organism; and ever afterwards it has been called "organic unity." With the backing of such authority, unity in variety was long thought to be the same as beauty; and, although this view is obviously one-sided, no one has since succeeded in persuading men that an object can be beautiful without unity.

Since art is expression, its unity is, unavoidably, an image of the unity of the things in nature and mind which it expresses. A lyric poem reflects the unity of mood that binds together the thoughts and images of the poet; the drama and novel, the unity of plan and purpose in the acts of men and the fateful sequence of causes and effects in their lives. The statue reflects the organic unity of the body; the painting, the spatial unity of visible things. In beautiful artifacts, the basal unity is the purpose or end embodied in the material structure.

But the unity of works of art is not wholly derivative; for it occurs in the free arts like music, where nothing is imitated, and even in the representative arts, as we have observed, it is closer than in the things which are imaged. Aesthetic unity is therefore unique and, if we would understand it, we must seek its reason in the peculiar nature and purpose of art. Since, moreover, art is a complex fact, the explanation of its unity is not simple; the unity itself is very intricate and depends upon many cooperating factors.

In the case of the imitative arts, taking the given unity of the objects represented as a basis, the superior unity of the image is partly due to the singleness of the artist's interest. For art, as we know, is never the expression of mere things, but of things so far as they have value. Out of the infinite fullness of nature and of life, the artist selects those elements that have a unique significance for him.

Music, when soft voices die, Vibrates in the memory; Odors, when sweet violets sicken, Live within the sense they quicken; Rose leaves, when the rose is dead, Are heaped for the beloved's bed; And so thy thoughts when thou art gone, Love itself shall slumber on.

Observe how, out of the countless things which he knows, the poet has chosen those which he feels akin to his faith in the immortality of love. The painter would not, if he could, reproduce all the elements of a face, but only those that are expressive of the interpretation of character he wishes to convey. The novelist and the dramatist proceed in a like selective fashion in the treatment of their material. In the lives of men there are a thousand actions and events--casual spoken words, recurrent processes such as eating and dressing, hours of idleness and futility which, because repet.i.tious, habitual, or inconsequential, throw no light upon that alone in which we are interested,--character and fortune. To describe a single example of these facts suffices. In the novel and drama, therefore, the personalities and life histories of men have a simplicity and singleness of direction not found in reality. The artist seeks everywhere the traits that individualize and characterize, and neglects all others.

Moreover, since the aim of art is to afford pleasure in the intuition of life, the artist will try to reveal the hidden unities that so delight the mind to discover. He will aim to penetrate beneath the surface of experience observed by common perception, to its more obscure logic underneath. In this way he will go beyond what the mere mechanism of imitation requires. The poet, for example, manifests latent emotional harmonies among the most widely sundered things. The subtle novelist shows how single elements of character, apparently isolated acts or trivial incidents, are fateful of consequences. He discloses the minute reactions of one personality upon another. Or he enters into the soul of man himself, into his private and individual selfhood, and uncovers the hidden connections between thought and feeling and impulse. Finally, he may take the wider sweep of society and tradition into view and track out their part in the molding of man and his fate. In the search for unity, the artist is on common ground with the man of science; but with this difference: the artist is concerned with laws operating in concrete, individual things in which he is interested; while the scientist formulates them in the abstract. For the artist, unity is valuable as characterizing a significant individual; for the scientist, it is valuable in itself, and the individual only as an example of it.

This same purpose of affording pleasure in sympathetic vision leads the artist not only to present the unity of life, but so to organize its material that it will be clear to the mind which perceives it. Too great a mult.i.tude of elements, elements that are not a.s.sorted into groups and tied by relations or principles, cannot be grasped. Hence the artist infuses into the world which he creates a new and wholly subjective simplicity and unity, to which there is no parallel in nature. The composition of elements in a picture does not correspond to any actual arrangement of elements in a landscape, but to the demands of visual perspicuity. The division of a novel into chapters, of the chapters into paragraphs, of the paragraphs into sentences, although it may answer in some measure to the objective divisions of the life-story related, corresponds much more closely to the subjective need for ready apprehension. The artist meets this need halfway in the organization of the material which he presents. Full beauty depends upon an adaptation of the object to the senses, attention, and synthetic functions of the mind. The long, rambling novel of the eighteenth century is a more faithful image of the fullness and diversity of life, but it answers ill to the limited sweep of the mind, its p.r.o.neness to fatigue, and its craving for wholeness of view.

But even all the reasons so far invoked--the necessity for significance, the interest in unity, the demand for perspicuity--do not, I think, suffice to explain the structure of works of art. For structure has, oftentimes, a direct emotional appeal, which has not yet been taken into account, and which is a leading motive for its presence. Consider, for example, symmetry. A symmetrical disposition of parts is indeed favorable to perspicuity; for it is easier to find on either side what we have already found on the other, the sight of one side preparing us for the sight of the other; and such an arrangement is flattering to our craving for unity, for we rejoice seeing the same pattern expressed in the two parts; yet the experience of symmetry is richer still: it includes an agreeable feeling of balance, steadfastness, stability. This is most evident in the case of visual objects, like a Greek vase, where there is a plain division between right and left similar halves; but it is also felt in music when there is a balance of themes in the earlier and later parts of a composition, and in literature in the well-balanced sentence, paragraph, or poem. To cite the very simplest example, if I read, "on the one hand ... on the other hand," I have a feeling of balanced tensions precisely a.n.a.logous to what I experience when I look at a vase. Structure is not a purely intellectual or perceptive affair; it is also motor and organic, and that means emotional. It is felt with the body as well as understood by the mind. I have used the case of symmetry to bring out this truth, but I might have used other types of unification, each of which has its unique feeling tone, as I shall show presently, after I have a.n.a.lyzed them.

Keeping in mind the motives which explain the structure of works of art, I wish now to distinguish and describe the chief types. There are, I think, three of these, of which each one may include important special forms--unity in variety, dominance, and equilibrium.

Unity in variety was the earliest of the types to be observed and is the most fundamental. It is the organic unity so often referred to in criticism. It involves, in the first place, wholeness or individuality.

Every work of art is a definite single thing, distinct and separate from other things, and not divisible into parts which are themselves complete works of art. No part can be taken away without damage to the whole, and when taken out of the whole, the part loses much of its own value. The whole needs all of its parts and they need it; "there they live and move and have their being." The unity is a unity of the variety and the variety is a differentiation of the unity.[Footnote: Cf. Lipps: _Aesthetik_, Bd. I, Drittes Kapitel.] The variety is of equal importance with the unity, for unity can a.s.sert itself and work only through the control of a multiplicity of elements. The a.n.a.logy between the unity of the work of art and the unity of the organism is still the most accurate and illuminating. For, like the work of art, the body is a self-sufficient and distinctive whole, whose unified life depends upon the functioning of many members, which, for their part, are dead when cut away from it.

The conception of unity in variety as organic represents an ideal or norm for art, which is only imperfectly realized in many works. There are few novels which would be seriously damaged by the omission of whole chapters, and many a rambling essay in good standing would permit pruning without injury, unless indeed we are made to feel that the apparently dispensable material really contributes something of fullness and exuberance, and so is not superfluous, after all. The unity in some forms of art is tighter than in others; in a play closer than in a novel; in a sonnet more compact than in an epic. In extreme examples, like _The Thousand and One Nights,_ the _Decameron,_ the _Canterbury Tales,_ the unity is almost wholly nominal, and the work is really a collection, not a whole. With all admissions, it remains true, however, that offenses against the principle of unity in variety diminish the aesthetic value of a work. These offenses are of two kinds--the inclusion of the genuinely irrelevant, and multiple unity, like double composition in a picture, or ambiguity of style in a building. There may be two or more parallel lines of action in a play or a novel, two or more themes in music, but they must be interwoven and interdependent.

Otherwise there occurs the phenomenon aptly called by Lipps "aesthetic rivalry"--each part claims to be the whole and to exclude its neighbor; yet being unable to do this, suffers injury through divided attention.

Unity in variety may exist in any one or more of three modes--the harmony or union of cooperating elements; the balance of contrasting or conflicting elements; the development or evolution of a process towards an end or climax. The first two are predominantly static or spatial; the last, dynamic and temporal. I know of no better way of indicating the characteristic quality of each than by citing examples.

Aesthetic harmony exists whenever some identical quality or form or purpose is embodied in various elements of a whole--sameness in difference. The repet.i.tion of the same s.p.a.ce-form in architecture, like the round arch and window in the Roman style; the recurrence of the same motive in music; the use of a single hue to color the different objects in a painting, as in a nocturne of Whistler: these are simple ill.u.s.trations of harmony. An almost equally simple case is gradation or lawful change of quality in s.p.a.ce and time--the increase or decrease of loudness in music of saturation or brightness of hue in painting, the gentle change of direction of a curved line. In these cases there is, of course, a dynamic or dramatic effect, if you take the elements in sequence; but when taken simultaneously and together, they are a harmony, not a development. Simplest of all is the harmony between like parts of regular figures, such as squares and circles; or between colors which are neighboring in hue. Harmonious also are characters in a story or play which are united by feelings of love, friendship, or loyalty. Thus there is harmony between Hamlet and Horatio, or between the Cid and his followers.

Aesthetic balance is the unity between elements which, while they oppose or conflict with one another, nevertheless need or supplement each other. Hostile things, enemies at war, business men that compete, persons that hate each other, have as great a need of their opponents, in order that there may be a certain type of life, as friends have, in order that there may be love between them; and in relation to each other they create a whole in the one case as in the other. There is as genuine a unity between contrasting colors and musical themes as there is between colors closely allied in hue or themes simply transposed in key. Contrasting elements are always the extremes of some series, and are unified, despite the contrast, because they supplement each other. Things merely different, no matter how different, cannot contrast, for there must be some underlying whole, to which both belong, in which they are unified. In order that this unity may be felt, it is often necessary to avoid absolute extremes, or at least to mediate between them. Among colors, for example, hues somewhat closer than the complementary are preferred to the latter, or, if the extremes are employed, each one leads up to the other through intermediate hues. The unity of contrasting colors is a balance because, as extremes, they take an equal hold on the attention. The well-known accentuation of contrasting elements does not interfere with the balance, because it is mutual. A balanced unity is also created by contrasts of character, as in Goethe's _Ta.s.so_, or by a conflict between social cla.s.ses or parties, as in Hauptmann's _Die Weber_.

Balanced, finally, is the unity between the elements of a painting, right and left, which draw the attention in opposite directions. The third type of unity appears in any process or sequence in which all the elements, one after another, contribute towards the bringing about of some end or result. It is the unity characteristic of all teleologically related facts. The sequence cannot be a mere succession or even a simple causal series, but must also be purposive, because, in order to be aesthetic, the goal which is reached must have value.

Causality is an important aspect of this type of unity, as in the drama, but only because a teleological series of actions depends upon a chain of causally related means and ends. The type is of two varieties: in the one, the movement is smooth, each element being harmoniously related to the last; in the other, it is difficult and dramatic, proceeding through the resolution of oppositions among its elements. The movement usually has three stages: an initial phase of introduction and preparation; a second phase of opposition and complication; then a final one, the climax or catastrophe, when the goal is reached; there may also be a fourth,--the working out of the consequences of this last. Ill.u.s.trations of this mode of unity are: the course of a story or a play from the introduction of the characters and the complication of the plot to the denouement or solving of the problem; the development of a character in a novel from a state of simplicity or innocence through storm and stress into maturity or ruin; the evolution of a sentiment in a sonnet towards its final statement in the last line or two; the melody, in its departure from the keynote, its going forth and return; the career of a line.

As I have indicated before, each type of unity has its specific emotional quality. The very word harmony which we use to denote the first mode is itself connotative of a way of being affected, of being moved emotionally. The mood of this mode is quiet, oneness, peace. We feel as if we were closely and compactly put together. If now, within the aesthetic whole, we emphasize the variety, we begin to lose the mood of peace; tensions arise, until, in the case of contrast and opposition, there is a feeling of conflict and division in the self; yet without loss of unity, because, if the whole is aesthetic, each of the opposing elements demands the other; hence there is balance between them, and this also we not only know to be there, but feel there. The characteristic mood of the evolutionary type of unity is equally unique--either a sense of easy motion, when the process is un.o.bstructed, or excitement and breathlessness, when there is opposition.

The different types of unity are by no means exclusive of each other and are usually found together in any complex work of art. Symmetry usually involves a combination of harmony and balance. The symmetrical halves of a Greek vase, for example, are harmonious in so far as their size and shape are the same, yet balanced as being disposed in opposite directions, right and left. Rhythm is temporal symmetry, and so also represents a combination of harmony and balance. Static rhythm is only apparent; for in every seeming case, the rhythm really pervades the succession of acts of attention to the elements rather than the elements themselves; a colonnade, for example, is rhythmical only when the attention moves from one column to another. There is harmony in rhythm, for there is always some law--metrical scheme in poetry, time in music, similarity of column and equality of interval between them in a colonnade--pervading the elements. But there is also balance; for as the elements enter the mind one after the other, there is rivalry between the element now occupying the focus of the attention and the one that is about to present an equal claim to this position. Because of its intrinsic value, we tend to hold on to each element as we hear or see it, but are forced to relinquish it for the sake of the one that follows; only for a moment can we keep both in the conscious span; the recurrence and overcoming of the resulting tension, as we follow the succession through, creates the pulsation so characteristic of rhythm. The opposition of the elements as in turn they crowd each other out does not, however, interfere with the harmony, for they have an existence all together in memory, where the law binding them can be felt,--a law which each element as it comes into consciousness is recognized as fulfilling. Since we usually look forward to the end of the rhythmical movement as a goal, rhythm often exists in combination with evolution, and is therefore the most inclusive of all artistic structural forms. In a poem, for example, the metrical rhythm is a framework overlying the development of the thought. Dramatic unity is found combined with balance even in the static arts, as, for example, in the combination of blue and gold, where the balance is not quite equal, because of a slight movement from the blue to the more brilliant and striking gold. I have already shown how harmony, opposition, and evolution may be combined in a melody. In the drama, also, all three are present. There is a balance of opposing and conflicting wills or forces; this is unstable; whence movement follows, leading on to the catastrophe, where the problem is solved; and throughout there is a single mood or atmosphere in which all partic.i.p.ate, creating an enveloping harmony despite the tension and action. And other ill.u.s.trations of combinations of types will come to the mind of every reader.

Each form of unity has its difficulties and dangers, which must be avoided if perfection is to be attained. In harmony there may be too much ident.i.ty and too little difference or variety, with the result that the whole becomes tedious and uninteresting. This is the fault of rigid symmetry and of all other simple geometrical types of composition, which, for this reason, have lost their old popularity in the decorative and pictorial arts. In balance, on the other hand, the danger is that there may be too great a variety, too strong an opposition; the elements tend to fly apart, threatening the integrity of the whole. For it is not sufficient that wholeness exist in a work of art; it must also be felt. For example, in Pre-Raphaelite paintings and in most of the Secession work of our own day, the color contrasts are too strong; there is no impression of visual unity. In the dramatic type of unity there are two chief dangers--that the evolution be tortuous, so that we lose our way in its bypaths and mazes; or, on the other hand, that the end be reached too simply and quickly; in the one case, we lose heart for the journey because of the obstacles; in the other, we lose interest and are bored for want of incidents.
