Works of architecture have further quite a special relation to light; they gain a double beauty in the full sunshine, with the blue sky as a background, and again they have quite a different effect by moonlight. Therefore, when a beautiful work of architecture is to be erected, special attention is always paid to the effects of the light and to the climate. The reason of all this is, indeed, principally that all the parts and their relations are only made clearly visible by a bright, strong light; but besides this I am of opinion that it is the function of architecture to reveal the nature of light just as it reveals that of things so opposite to it as gravity and rigidity. For the light is intercepted, confined, and reflected by the great opaque, sharply outlined, and variously formed masses of stone, and thus it unfolds its nature and qualities in the purest and clearest way, to the great pleasure of the beholders, for light is the most joy-giving of things, as the condition and the objective correlative of the most perfect kind of knowledge of perception.
Now, because the Ideas which architecture brings to clear perception, are the lowest grades of the objectivity of will, and consequently their objective significance, which architecture reveals to us, is comparatively small; the æsthetic pleasure of looking at a beautiful building in a good light will lie, not so much in the comprehension of the Idea, as in the subjective correlative which accompanies this comprehension; it will consist pre-eminently in the fact that the beholder, set free from the kind of knowledge that belongs to the individual, and which serves the will and follows the principle of sufficient reason, is raised to that of the pure subject of knowing free from will. It will consist then principally in pure contemplation itself, free from all the suffering of will and of individuality. In this respect the opposite of architecture, and the other extreme of the series of the fine arts, is the drama, which brings to knowledge the most significant Ideas. Therefore in the æsthetic pleasure afforded by the drama the objective side is throughout predominant.
Architecture has this distinction from plastic art and poetry: it does not give us a copy but the thing itself. It does not repeat, as they do, the known Idea, so that the artist lends his eyes to the beholder, but in it the artist merely presents the object to the beholder, and facilitates for him the comprehension of the Idea by bringing the actual, individual object to a distinct and complete expression of its nature.
Unlike the works of the other arts, those of architecture are very seldom executed for purely æsthetic ends. These are generally subordinated to other useful ends which are foreign to art itself. Thus the great merit of the architect consists in achieving and attaining the pure æsthetic ends, in spite of their subordination to other ends which are foreign to them. This he does by cleverly adapting them in a variety of ways to the arbitrary ends in view, and by rightly judging which form of æsthetical architectonic beauty is compatible and may be associated with a temple, which with a palace, which with a prison, and so forth. The more a harsh climate increases these demands of necessity and utility, determines them definitely, and prescribes them more inevitably, the less free play has beauty in architecture. In the mild climate of India, Egypt, Greece, and Rome, where the demands of necessity were fewer and less definite, architecture could follow its æsthetic ends with the greatest freedom. But under a northern sky this was sorely hindered. Here, when caissons, pointed roofs and towers were what was demanded, architecture could only unfold its own beauty within very narrow limits, and therefore it was obliged to make amends by resorting all the more to the borrowed ornaments of sculpture, as is seen in Gothic architecture.
We thus see that architecture is greatly restricted by the demands of necessity and utility; but on the other hand it has in them a very powerful support, for, on account of the magnitude and costliness of its works, and the narrow sphere of its æsthetic effect, it could not continue to exist merely as a fine art, if it had not also, as a useful and necessary profession, a firm and honourable place among the occupations of men. It is the want of this that prevents another art from taking its place beside architecture as a sister art, although in an æsthetical point of view it is quite properly to be classed along with it as its counterpart; I mean artistic arrangements of water. For what architecture accomplishes for the Idea of gravity when it appears in connection with that of rigidity, hydraulics accomplishes for the same Idea, when it is connected with fluidity, i.e., formlessness, the greatest mobility and transparency. Leaping waterfalls foaming and tumbling over rocks, cataracts dispersed into floating spray, springs gushing up as high columns of water, and clear reflecting lakes, reveal the Ideas of fluid and heavy matter, in precisely the same way as the works of architecture unfold the Ideas of rigid matter. Artistic hydraulics, however, obtains no support from practical hydraulics, for, as a rule, their ends cannot be combined; yet, in exceptional cases, this happens; for example, in the Cascata di Trevi at Rome.52
§ 44. What the two arts we have spoken of accomplish for these lowest grades of the objectivity of will, is performed for the higher grades of vegetable nature by artistic horticulture. The landscape beauty of a scene consists, for the most part, in the multiplicity of natural objects which are present in it, and then in the fact that they are clearly separated, appear distinctly, and yet exhibit a fitting connection and alternation. These two conditions are assisted and promoted by landscape-gardening, but it has by no means such a mastery over its material as architecture, and therefore its effect is limited. The beauty with which it is concerned belongs almost exclusively to nature; it has done little for it; and, on the other hand, it can do little against unfavourable nature, and when nature works, not for it, but against it, its achievements are small.
The vegetable world offers itself everywhere for æsthetic enjoyment without the medium of art; but so far as it is an object of art, it belongs principally to landscape-painting; to the province of which all the rest of unconscious nature also belongs. In paintings of still life, and of mere architecture, ruins, interiors of churches, &c., the subjective side of æsthetic pleasure is predominant, i.e., our satisfaction does not lie principally in the direct comprehension of the represented Ideas, but rather in the subjective correlative of this comprehension, pure, will-less knowing. For, because the painter lets us see these things through his eyes, we at once receive a sympathetic and reflected sense of the deep spiritual peace and absolute silence of the will, which were necessary in order to enter with knowledge so entirely into these lifeless objects, and comprehend them with such love, i.e., in this case with such a degree of objectivity. The effect of landscape-painting proper is indeed, as a whole, of this kind; but because the Ideas expressed are more distinct and significant, as higher grades of the objectivity of will, the objective side of æsthetic pleasure already comes more to the front and assumes as much importance as the subjective side. Pure knowing as such is no longer the paramount consideration, for we are equally affected by the known Platonic Idea, the world as idea at an important grade of the objectification of will.
But a far higher grade is revealed by animal painting and sculpture. Of the latter we have some important antique remains; for example, horses at Venice, on Monte Cavallo, and on the Elgin Marbles, also at Florence in bronze and marble; the ancient boar, howling wolves, the lions in the arsenal at Venice, also in the Vatican a whole room almost filled with ancient animals, &c. In these representations the objective side of æsthetic pleasure obtains a marked predominance over the subjective. The peace of the subject which knows these Ideas, which has silenced its own will, is indeed present, as it is in all æsthetic contemplation; but its effect is not felt,
