The Sense of Beauty Part 4

- 19. The most remarkable and characteristic problem of aesthetics is that of beauty of form. Where there is a sensuous delight, like that of colour, and the impression of the object is in its elements agreeable, we have to look no farther for an explanation of the charm we feel. Where there is expression, and an object indifferent to the senses is a.s.sociated with other ideas which are interesting, the problem, although complex and varied, is in principle comparatively plain. But there is an intermediate effect which is more mysterious, and more specifically an effect of beauty. It is found where sensible elements, by themselves indifferent, are so united as to please in combination. There is something unexpected in this phenomenon, so much so that those who cannot conceive its explanation often rea.s.sure themselves by denying its existence. To reduce beauty of form, however, to beauty of elements would not be easy, because the creation and variation of effect, by changing the relation of the simplest lines, offers too easy an experiment in refutation. And it would, moreover, follow to the comfort of the vulgar that all marble houses are equally beautiful.

To attribute beauty of form to expression is more plausible. If I take the meaningless short lines in the figure and arrange them in the given ways, intended to represent the human face, there appear at once notably different aesthetic values.

[Ill.u.s.tration of long and short lines]

[Ill.u.s.tration of lines arranged into three facial profiles]

Two of the forms are differently grotesque and one approximately beautiful. Now these effects are due to the expression of the lines; not only because they make one think of fair or ugly faces, but because, it may be said, these faces would in reality be fair or ugly according to their expression, according to the vital and moral a.s.sociations of the different types.

Nevertheless, beauty of form cannot be reduced to expression without denying the existence of immediate aesthetic values altogether, and reducing them all to suggestions of moral good. For if the object expressed by the form, and from which the form derives its value, had itself beauty of form, we should not advance; we must come somewhere to the point where the expression is of something else than beauty; and this something else would of course be some practical or moral good. Moralists are fond of such an interpretation, and it is a very interesting one. It puts beauty in the same relation to morals in which morals stand to pleasure and pain; both would be intuitions, qualitatively new, but with the same materials; they would be new perspectives of the same object.

But this theory is actually inadmissible. Innumerable aesthetic effects, indeed all specific and unmixed ones, are direct trans.m.u.tations of pleasures and pains; they express nothing extrinsic to themselves, much less moral excellences. The detached lines of our figure signify nothing, but they are not absolutely uninteresting; the straight line is the simplest and not the least beautiful of forms. To say that it owes its interest to the thought of the economy of travelling over the shortest road, or of other practical advantages, would betray a feeble hold on psychological reality. The impression of a straight line differs in a certain almost emotional way from that of a curve, as those of various curves do from one another. The quality of the sensation is different, like that of various colours or sounds. To attribute the character of these forms to a.s.sociation would be like explaining sea-sickness as the fear of shipwreck. There is a distinct quality and value, often a singular beauty, in these simple lines that is intrinsic in the perception of their form.

It would be pedantic, perhaps, anywhere but in a treatise on aesthetics, to deny to this quality the name of expression; we might commonly say that the circle has one expression and the oval another. But what does the circle express except circularity, or the oval except the nature of the ellipse? Such expression _expresses_ nothing; it is really impression. There may be a.n.a.logy between it and other impressions; we may admit that odours, colours, and sounds correspond, and may mutually suggest one another; but this a.n.a.logy is a superadded charm felt by very sensitive natures, and does not const.i.tute the original value of the sensations. The common emotional tinge is rather what enables them to suggest one another, and what makes them comparable. Their expression, such as it is, is therefore due to the accident that both feelings have a kindred quality; and this quality has its effectiveness for sense independently of the perception of its recurrence in a different sphere. We shall accordingly take care to reserve the term "expression" for the suggestion of some other and a.s.signable object, from which the expressive thing borrows an interest; and we shall speak of the intrinsic quality of forms as their emotional tinge or specific value.

_Physiology of the perception of form._

- 20. The charm of a line evidently consists in the relation of its parts; in order to understand this interest in spatial relations, we must inquire how they are perceived.[4] If the eye had its sensitive surface, the retina, exposed directly to the light, we could never have a perception of form any more than in the nose or ear, which also perceive the object through media. When the perception is not through a medium, but direct, as in the case of the skin, we might get a notion of form, because each point of the object would excite a single point in the skin, and as the sensations in different parts of the skin differ in quality, a manifold of sense, in which discrimination of parts would be involved, could be presented to the mind. But when the perception is through a medium, a difficulty arises.

Any point, a, in the object will send a ray to every point, _a', b', c',_ of the sensitive surface; every point of the retina will therefore be similarly affected, since each will receive rays from every part of the object.

[Ill.u.s.tration of light rays]

If all the rays from one point of the object, a, are to be concentrated on a corresponding point of the retina, a which would then become the exclusive representative of a, we must have one or more refracting surfaces interposed, to gather the rays together.

The presence of the lens, with its various coatings, has made representation of point by point possible for the eye. The absence of such an instrument makes the same sort of representation impossible to other senses, such as the nose, which does not smell in one place the effluvia of one part of the environment and in another place the effluvia of another, but smells indiscriminately the combination of all. Eyes without lenses like those possessed by some animals, undoubtedly give only a consciousness of diffused light, without the possibility of boundaries or divisions in the field of view. The abstraction of colour from form is therefore by no means an artificial one, since, by a simplification of the organ of sense, one may be perceived without the other.

But even if the lens enables the eye to receive a distributed image of the object, the manifold which consciousness would perceive would not be necessarily a manifold of parts juxtaposed in s.p.a.ce.

Bach point of the retina might send to the brain a detached impression; these might be comparable, but not necessarily in their spatial position. The ear sends to the brain such a manifold of impressions (since the ear also has an apparatus by which various external differences in rapidity of vibrations are distributed into different parts of the organ). But this discriminated manifold is a manifold of pitches, not of positions. How does it happen that the manifold conveyed by the optic nerve appears in consciousness as spatial, and that the relation between its elements is seen as a relation of position?

An answer to this question has been suggested by various psychologists. The eye, by an instinctive movement, turns so as to bring every impression upon that point of the retina, near its centre, which has the acutest sensibility. A series of muscular sensations therefore always follows upon the conspicuous excitement of any outlying point. The object, as the eye brings it to the centre of vision, excites a series of points upon the retina; and the local sign, or peculiar quality of sensation, proper to each of these spots, is a.s.sociated with that series of muscular feelings involved in turning the eyes. These feelings henceforth revive together; it is enough that a point in the periphery of the retina should receive a ray, for the mind to feel, together with that impression, the suggestion of a motion, and of the line of points that lies between the excited point and the centre of vision. A network of a.s.sociations is thus formed, whereby the sensation of each retinal point is connected with all the others in a manner which is that of points in a plane. Every visible point becomes thus a point in a field, and has a felt radiation of lines of possible motion about it. Our notion of visual s.p.a.ce has this origin, since the manifold of retinal impressions is distributed in a manner which serves as the type and exemplar of what we mean by a surface.

_Values of geometrical figures._

- 21. The reader will perhaps pardon these details and the strain they put on his attention, when he perceives how much they help us to understand the value of forms. The sense, then, of the position of any point consists in the tensions in the eye, that not only tends to bring that point to the centre of vision, but feels the suggestion of all the other points which are related to the given one in the web of visual experience. The definition of s.p.a.ce as the possibility of motion is therefore an accurate and significant one, since the most direct and native perception of s.p.a.ce we can have is the awakening of many tendencies to move our organs.

For example, if a circle is presented, the eye will fall upon its centre, as to the centre of gravity, as it were, of the balanced attractions of all the points; and there will be, in that position, an indifference and sameness of sensation, in whatever direction some accident moves the eye, that accounts very well for the emotional quality of the circle. It is a form which, although beautiful in its purity and simplicity, and wonderful in its continuity, lacks any stimulating quality, and is often ugly in the arts, especially when found in vertical surfaces where it is not always seen in perspective.

For horizontal surfaces it is better because it is there always an ellipse to vision, and the ellipse has a less dull and stupefying effect. The eye can move easily, organize and subordinate its parts, and its relations to the environment are not similar in all directions.

Small circles, like b.u.t.tons, are not in the same danger of becoming ugly, because the eye considers them as points, and they diversify and help to divide surfaces, without appearing as surfaces themselves.

The straight line offers a curious object for a.n.a.lysis. It is not for the eye a very easy form to grasp. We bend it or we leave it.

Unless it pa.s.ses through the centre of vision, it is obviously a tangent to the points which have a.n.a.logous relations to that centre.

The local signs or tensions of the points in such a tangent vary in an unseizable progression; there is violence in keeping to it, and the effect is forced. This makes the dry and stiff quality of any long straight line, which the skilful Greeks avoided by the curves of their columns and entablatures, and the less economical barbarians by a profusion of interruptions and ornaments.

The straight line, when made the direct object of attention, is, of course, followed by the eye and not seen by the outlying parts of the retina in one eccentric position. The same explanation is good for this more common case, since the consciousness that the eye travels in a straight line consists in the surviving sense of the previous position, and in the manner in which the tensions of these various positions overlap. If the tensions change from moment to moment entirely, we have a broken, a fragmentary effect, as that of zigzag, where all is dropping and picking up again of a.s.sociated motions; in the straight line, much prolonged, we have a gradual and inexorable rending of these tendencies to a.s.sociated movements.

In the curves we call flowing and graceful, we have, on the contrary, a more natural and rhythmical set of movements in the optic muscles; and certain points in the various gyrations make rhymes and a.s.sonances, as it were, to the eye that reaches them.

We find ourselves at every turn reawakening, with a variation, the sense of the previous position. It is easy to understand by a.n.a.logy with the superficially observed conditions of pleasure, that such rhythms and harmonies should be delightful. The deeper question of the physical basis of pleasure we have not intended to discuss.

Suffice it that measure, in quant.i.ty, in intensity, and in time, must involve that physiological process, whatever it may be, the consciousness of which is pleasure.

_Symmetry._

- 22. An important exemplification of these physiological principles is found in the charm of symmetry. When for any reason the eye is to be habitually directed to a single point, as to the opening of a gate or window, to an altar, a throne, a stage, or a fireplace, there will be violence and distraction caused by the tendency to look aside in the recurring necessity of looking forward, if the object is not so arranged that the tensions of eye are balanced, and the centre of gravity of vision lies in the point which one is obliged to keep in sight. In all such objects we therefore require bilateral symmetry. The necessity of vertical symmetry is not felt because the eyes and head do not so readily survey objects from top to bottom as from side to side. The inequality of the upper and lower parts does not generate the same tendency to motion, the same restlessness, as does the inequality of the right and left sides of an object in front of us. The comfort and economy that comes from muscular balance in the eye, is therefore in some cases the source of the value of symmetry.[5]

In other cases symmetry appeals to us through the charm of recognition and rhythm. When the eye runs over a facade, and finds the objects that attract it at equal intervals, an expectation, like the antic.i.p.ation of an inevitable note or requisite word, arises in the mind, and its non-satisfaction involves a shock. This shock, if caused by the emphatic emergence of an interesting object, gives the effect of the picturesque; but when it comes with no compensation, it gives us the feeling of ugliness and imperfection -- the defect which symmetry avoids. This kind of symmetry is accordingly in itself a negative merit, but often the condition of the greatest of all merits, -- the permanent power to please. It contributes to that completeness which delights without stimulating, and to which our jaded senses return gladly, after all sorts of extravagances, as to a kind of domestic peace. The inwardness and solidity of this quiet beauty comes from the intrinsic character of the pleasure which makes it up. It is no advent.i.tious charm; but the eye in its continual pa.s.sage over the object finds always the same response, the same adequacy; and the very process of perception is made delightful by the object's fitness to be perceived. The parts, thus coalescing, form a single object, the unity and simplicity of which are based upon the rhythm and correspondence of its elements.

Symmetry is here what metaphysicians call a principle of individuation. By the emphasis which it lays upon the recurring elements, it cuts up the field into determinate units; all that lies between the beats is one interval, one individual. If there were no recurrent impressions, no corresponding points, the field of perception would remain a fluid continuum, without defined and recognizable divisions. The outlines of most things are symmetrical because we choose what symmetrical lines we find to be the boundaries of objects. Their symmetry is the condition of their unity, and their unity of their individuality and separate existence.

Experience, to be sure, can teach us to regard unsymmetrical objects as wholes, because their elements move and change together in nature; but this is a principle of individuation, _a posteriori,_ founded on the a.s.sociation of recognized elements.

These elements, to be recognized and seen to go together and form one thing, must first be somehow discriminated; and the symmetry, either of their parts, or of their position as wholes, may enable us to fix their boundaries and to observe their number. The category of unity, which we are so constantly imposing upon nature and its parts, has symmetry, then, for one of its instruments, for one of its bases of application.

If symmetry, then, is a principle of individuation and helps us to distinguish objects, we cannot wonder that it helps us to enjoy the perception. For our intelligence loves to perceive; water is not more grateful to a parched throat than a principle of comprehension to a confused understanding. Symmetry clarifies, and we all know that light is sweet. At the same time, we can see why there are limits to the value of symmetry. In objects, for instance, that are too small or too diffused for composition, symmetry has no value. In an avenue symmetry is stately and impressive, but in a large park, or in the plan of a city, or the side wall of a gallery it produces monotony in the various views rather than unity in any one of them. Greek temples, never being very large, were symmetrical on all their facades; Gothic churches were generally designed to be symmetrical only in the west front, and in the transepts, while the side elevation as a whole was eccentric.

This was probably an accident, due to the demands of the interior arrangement; but it was a fortunate one, as we may see by contrasting its effect with that of our stations, exhibition buildings, and other vast structures, where symmetry is generally introduced even in the most extensive facades which, being too much prolonged for their height, cannot be treated as units. The eye is not able to take them in at a glance, and does not get the effect of repose from the balance of the extremes, while the mechanical sameness of the sections, surveyed in succession, makes the impression of an unmeaning poverty of resource.

Symmetry thus loses its value when it cannot, on account of the size of the object, contribute to the unity of our perception. The synthesis which it facilitates must be instantaneous. If the comprehension by which we unify our object is discursive, as, for instance, in conceiving the arrangement and numbering of the streets of New York, or the plan of the Escurial, the advantage of symmetry is an intellectual one; we can better imagine the relations of the parts, and draw a map of the whole in the fancy; but there is no advantage to direct perception, and therefore no added beauty.

Symmetry is superfluous in those objects. Similarly animal and vegetable forms gain nothing by being symmetrically displayed, if the sense of their life and motion is to be given. When, however, these forms are used for mere decoration, not for the expression of their own vitality, then symmetry is again required to accentuate their unity and organization. This justifies the habit of conventionalizing natural forms, and the tendency of some kinds of hieratic art, like the Byzantine or Egyptian, to affect a rigid symmetry of posture. We can thereby increase the unity and force of the image without suggesting that individual life and mobility, which would interfere with the religious function of the object, as the symbol and embodiment of an impersonal faith.

_Form the unity of a manifold._

- 23. Symmetry is evidently a kind of unity in variety, where a whole is determined by the rhythmic repet.i.tion of similars. We have seen that it has a value where it is an aid to unification. Unity would thus appear to be the virtue of forms; but a moment's reflection will show us that unity cannot be absolute and be a form; a form is an aggregation, it must have elements, and the manner in which the elements are combined const.i.tutes the character of the form. A perfectly simple perception, in which there was no consciousness of the distinction and relation of parts, would not be a perception of form; it would be a sensation. Physiologically these sensations may be aggregates and their values, as in the case of musical tones, may differ according to the manner in which certain elements, beats, vibrations, nervous processes, or what not, are combined; but for consciousness the result is simple, and the value is the pleasantness of a datum and not of a process. Form, therefore, does not appeal to the unattentive; they get from objects only a vague sensation which may in them awaken extrinsic a.s.sociations; they do not stop to survey the parts or to appreciate their relation, and consequently are insensible to the various charms of various unifications; they can find in objects only the value of material or of function, not that of form.

Beauty of form, however, is what specifically appeals to an aesthetic nature; it is equally removed from the crudity of formless stimulation and from the emotional looseness of reverie and discursive thought. The indulgence in sentiment and suggestion, of which our time is fond, to the sacrifice of formal beauty, marks an absence of cultivation as real, if not as confessed, as that of the barbarian who revels in gorgeous confusion.

The synthesis, then, which const.i.tutes form is an activity of the mind; the unity arises consciously, and is an insight into the relation of sensible elements separately perceived. It differs from sensation in the consciousness of the synthesis, and from expression in the h.o.m.ogeneity of the elements, and in their common presence to sense.

The variety of forms depends upon the character of the elements and on the variety of possible methods of unification. The elements may be all alike, and their only diversity be numerical. Their unity will then be merely the sense of their uniformity.[6] Or they may differ in kind, but so as to compel the mind to no particular order in their unification. Or they may finally be so const.i.tuted that they suggest inevitably the scheme of their unity; in this case there is organization in the object, and the synthesis of its parts is one and pre-determinate. We shall discuss these various forms in succession, pointing out the effects proper to each.

_Multiplicity in uniformity._

- 24. The radical and typical case of the first kind of unity in variety is found in the perception of extension itself. This perception, if we look to its origin, may turn out to be primitive; no doubt the feeling of "crude extensity" is an original sensation; every inference, a.s.sociation, and distinction is a thing that looms up suddenly before the mind, and the nature and actuality of which is a datum of what -- to indicate its irresistible immediacy and indescribability -- we may well call sense. Forms are seen, and if we think of the origin of the perception, we may well call this vision a sensation. The distinction between a sensation of form, however, and one which is formless, regards the content and character, not the genesis of the perception. A distinction and a.s.sociation, or an inference, is a direct experience, a sensible fact; but it is the experience of a process, of a motion between two terms, and a consciousness of their coexistence and distinction; it is a feeling of relation. Now the sense of s.p.a.ce is a feeling of this kind; the essence of it is the realization of a variety of directions and of possible motions, by which the relation of point to point is vaguely but inevitably given. The perception of extension is therefore a perception of form, although of the most rudimentary kind. It is merely _Auseinandersein,_ and we might call it the _materia prima_ of form, were it not capable of existing without further determination. For we can have the sense of s.p.a.ce without the sense of boundaries; indeed, this intuition is what tempts us to declare s.p.a.ce infinite. s.p.a.ce would have to consist of a finite number of juxtaposed blocks, if our experience of extension carried with it essentially the realization of limits.

The aesthetic effect of extensiveness is also entirely different from that of particular shapes. Some things appeal to us by their surfaces, others by the lines that limit those surfaces. And this effect of surface is not necessarily an effect of material or colour; the evenness, monotony, and vastness of a great curtain of colour produce an effect which is that of the extreme of uniformity in the extreme of multiplicity; the eye wanders over a fluid infinity of unrecognizable positions, and the sense of their numberlessness and continuity is precisely the source of the emotion of extent. The emotion is primary and has undoubtedly a physiological ground, while the idea of size is secondary and involves a.s.sociations and inferences. A small photograph of St. Peter's gives the idea of size; as does a distant view of the same object. But this is of course dependent on our realization of the distance, or of the scale of the representation. The value of size becomes immediate only when we are at close quarters with the object; then the surfaces really subtend a large angle in the field of vision, and the sense of vastness establishes its standard, which can afterwards be applied to other objects by a.n.a.logy and contrast. There is also, to be sure, a moral and practical import in the known size of objects, which, by a.s.sociation, determines their dignity; but the pure sense of extension, based upon the attack of the object upon the apperceptive resources of the eye, is the truly aesthetic value which it concerns us to point out here, as the most rudimentary example of form.

Although the effect of extension is not that of material, the two are best seen in conjunction. Material must appear in some form; but when its beauty is to be made prominent, it is well that this form should attract attention as little as possible to itself. Now, of all forms, absolute uniformity in extension is the simplest and most allied to the material; it gives the latter only just enough form to make it real and perceptible. Very rich and beautiful materials therefore do well to a.s.sume this form. You will spoil the beauty you have by superimposing another; as if you make a statue of gold, or flute a jasper column, or bedeck a velvet cloak. The beauty of stuffs appears when they are plain. Even stone gives its specific quality best in great unbroken s.p.a.ces of wall; the simplicity of the form emphasizes the substance. And again, the effect of extensity is never long satisfactory unless it is superinduced upon some material beauty; the dignity of great hangings would suffer if they were not of damask, but of cotton, and the vast smoothness of the sky would grow oppressive if it were not of so tender a blue.

_Example of the stars._

- 25. Another beauty of the sky -- the stars -- offers so striking and fascinating an ill.u.s.tration of the effect of multiplicity in uniformity, that I am tempted to a.n.a.lyze it at some length. To most people, I fancy, the stars are beautiful; but if you asked why, they would be at a loss to reply, until they remembered what they had heard about astronomy, and the great size and distance and possible habitation of those orbs. The vague and illusive ideas thus aroused fall in so well with the dumb emotion we were already feeling, that we attribute this emotion to those ideas, and persuade ourselves that the power of the starry heavens lies in the suggestion of astronomical facts.

The idea of the insignificance of our earth and of the incomprehensible multiplicity of worlds is indeed immensely impressive; it may even be intensely disagreeable. There is something baffling about infinity; in its presence the sense of finite humility can never wholly banish the rebellious suspicion that we are being deluded. Our mathematical imagination is put on the rack by an attempted conception that has all the anguish of a nightmare and probably, could we but awake, all its laughable absurdity. But the obsession of this dream is an intellectual puzzle, not an aesthetic delight. It is not essential to our admiration. Before the days of Kepler the heavens declared the glory of G.o.d; and we needed no calculation of stellar distances, no fancies about a plurality of worlds, no image of infinite s.p.a.ces, to make the stars sublime.

Had we been taught to believe that the stars governed our fortunes, and were we reminded of fate whenever we looked at them, we should similarly tend to imagine that this belief was the source of their sublimity; and, if the superst.i.tion were dispelled, we should think the interest gone from the apparition. But experience would soon undeceive us, and prove to us that the sensuous character of the object was sublime in itself. Indeed, on account of that intrinsic sublimity the sky can be fitly chosen as a symbol for a sublime conception; the common quality in both makes each suggest the other. For that reason, too, the parable of the natal stars governing our lives is such a natural one to express our subjection to circ.u.mstances, and can be transformed by the stupidity of disciples into a literal tenet. In the same way, the kinship of the emotion produced by the stars with the emotion proper to certain religious moments makes the stars seem a religious object. They become, like impressive music, a stimulus to worship. But fortunately there are experiences which remain untouched by theory, and which maintain the mutual intelligence of men through the estrangements wrought by intellectual and religious systems. When the superstructures crumble, the common foundation of human sentience and imagination is exposed beneath.

The intellectual suggestion of the infinity of nature can, moreover, be awakened by other experiences which are by no means sublime.

A heap of sand will involve infinity as surely as a universe of suns and planets. Any object is infinitely divisible and, when we press the thought, can contain as many worlds with as many winged monsters and ideal republics as can the satellites of Sirius. But the infinitesimal does not move us aesthetically; it can only awaken an amused curiosity. The difference cannot lie in the import of the idea, which is objectively the same in both cases. It lies in the different immediate effect of the crude images which give us the type and meaning of each; the crude image that underlies the idea of the infinitesimal is the dot, the poorest and most uninteresting of impressions; while the crude image that underlies the idea of infinity is s.p.a.ce, multiplicity in uniformity, and this, as we have seen, has a powerful effect on account of the breadth, volume, and omnipresence of the stimulation. Every point in the retina is evenly excited, and the local signs of all are simultaneously felt. This equable tension, this balance and elasticity in the very absence of fixity, give the vague but powerful feeling that we wish to describe.

Did not the infinite, by this initial a.s.sault upon our senses, awe us and overwhelm us, as solemn music might, the idea of it would be abstract and moral like that of the infinitesimal, and nothing but an amusing curiosity.

Nothing is objectively impressive; things are impressive only when they succeed in touching the sensibility of the observer, by finding the avenues to his brain and heart. The idea that the universe is a mult.i.tude of minute spheres circling, like specks of dust, in a dark and boundless void, might leave us cold and indifferent, if not bored and depressed, were it not that we identify this hypothetical scheme with the visible splendour, the poignant intensity, and the baffling number of the stars. So far is the object from giving value to the impression, that it is here, as it must always ultimately be, the impression that gives value to the object. For all worth leads us back to actual feeling somewhere, or else evaporates into nothing -- into a word and a superst.i.tion.
