necessary a relation that, where it is possible, if any one part were taken away, the whole would fall to pieces. For just because each part bears just as much as it conveniently can, and each is supported just where it requires to be and just to the necessary extent, this opposition unfolds itself, this conflict between rigidity and gravity, which constitutes the life, the manifestation of will, in the stone, becomes completely visible, and these lowest grades of the objectivity of will reveal themselves distinctly. In the same way the form of each part must not be determined arbitrarily, but by its end, and its relation to the whole. The column is the simplest form of support, determined simply by its end: the twisted column is tasteless; the four-cornered pillar is in fact not so simple as the round column, though it happens that it is easier to make it. The forms also of frieze, rafter, roof, and dome are entirely determined by their immediate end, and explain themselves from it. The decoration of capitals, &c, belongs to sculpture, not to architecture, which admits it merely as extraneous ornament, and could dispense with it. According to what has been said, it is absolutely necessary, in order to understand the æsthetic satisfaction afforded by a work of architecture, to have immediate knowledge through perception of its matter as regards its weight, rigidity, and cohesion, and our pleasure in such a work would suddenly be very much diminished by the discovery that the material used was pumice-stone; for then it would appear to us as a kind of sham building. We would be affected in almost the same way if we were told that it was made of wood, when we had supposed it to be of stone, just because this alters and destroys the relation between rigidity and gravity, and consequently the significance and necessity of all the parts, for these natural forces reveal themselves in a far weaker degree in a wooden building. Therefore no real work of architecture as a fine art can be made of wood, although it assumes all forms so easily; this can only be
