THE PLATONIC IDEA: THE OBJECT OF ART. 279
explained by our theory. If we were distinctly told that a building, the sight of which gave us pleasure, was made of different kinds of material of very unequal weight and consistency, but not distinguishable to the eye, the whole building would become as utterly incapable of affording us pleasure as a poem in an unknown language. All this proves that architecture does not affect us mathematically, but also dynamically, and that what speaks to us through it, is not mere form and symmetry, but rather those fundamental forces of nature, those first Ideas, those lowest grades of the objectivity of will. The regularity of the building and its parts is partly produced by the direct adaptation of each member to the stability of the whole, partly it serves to facilitate the survey and comprehension of the whole, and finally, regular figures to some extent enhance the beauty because they reveal the constitution of space as such. But all this is of subordinate value and necessity, and by no means the chief concern; indeed, symmetry is not invariably demanded, as ruins are still beautiful.
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
