The beauty of the world, indeed, cannot be attributed wholly or mainly to pleasures thus attached to abstracted sensations. It is only the beauty of the materials of things which is drawn from the pleasures of sensation. By far the most important effects are not attributable to these materials, but to their arrangement and their ideal relations. We have yet to study those processes of our mind by which this arrangement and these relations are conceived; and the pleasures which we can attach to these processes may then be added to the pleasures attached to sense as further and more subtle elements of beauty. But before passing to the consideration of this more intricate subject, we may note that however subordinate the beauty may be which a garment, a building, or a poem derives from its sensuous material, yet the presence of this sensuous material is indispensable. Form cannot be the form of nothing. If, then, in finding or creating beauty, we ignore the materials of things, and attend only to their form, we miss an ever-present opportunity to heighten our effects. For whatever delight the form may bring, the material might have given delight already, and so much would have been gained towards the value of the total result. Sensuous beauty is not the greatest or most important element of effect, but it is the most primitive and fundamental, and the most universal. There is no effect of form which an effect of material could not enhance, and this effect of material, underlying that of form, raises the latter to a higher power and gives the beauty of the object a certain poignancy, thoroughness, and infinity which it otherwise would have lacked. The Parthenon not in marble, the king's crown not of gold, and the stars not of fire, would be feeble and prosaic things. The greater hold which material beauty has upon the senses, stimulates us here, where the form is also sublime, and lifts and intensifies our emotions. We need this stimulus if our perceptions are to reach the highest pitch of strength and acuteness. Nothing can be ravishing that is not beautiful pervasively.
