The first and last lesson of the useful arts is, that Nature tyrannizes over our works. They must be conformed to her law, or they will be ground to powder by her omnipresent activity. Nothing droll, nothing whimsical will endure. Nature is ever interfering with Art. You cannot build your house or pagoda as you will, but as you must. There is a quick bound set to your caprice. The leaning tower can only lean so far. The verandah or pagoda roof can curve upward only to a certain point. The slope of your roof is determined by the weight of snow. It is only within narrow limits that the discretion of the architect may range: gravity, wind, sun, rain, the size of men and animals, and such like, have more to say than he. It is the law of fluids that prescribes the shape of the boat,--keel, rudder, and bows,--and, in the finer fluid above, the form and tackle of the sails. Man seems to have no option about his tools, but merely the necessity to learn from Nature what will fit best, as if he were fitting a screw or a door. Beneath a necessity thus almighty, what is artificial in man’s life seems insignificant. He seems to take his task so minutely from intimations of Nature, that his works become as it were hers, and he is no longer free. But if we work within this limit, she yields us all her strength. All powerful action is performed by bringing the forces of nature to bear upon our objects. We do not grind corn or lift the loom by our own strength, but we build a mill in such position as to set the north wind to play upon our instrument, or the elastic force of steam, or the ebb and flow of the sea. So in our handiwork, we do few things by muscular force, but we place ourselves in such attitudes as to bring the force of gravity, that is, the weight of the planet, to bear upon the spade or the axe we wield. In short, in all our operations we seek not to use our own, but to bring a quite infinite force to bear. Let us now consider this law as it affects the works that have beauty for their end, that is, the productions of the Fine Arts. Here again the prominent fact is subordination of man. His art is the least part of his work of art. A great deduction is to be made before we can know his proper contribution to it. Music, Eloquence, Poetry, Painting, Sculpture, Architecture. This is a rough enumeration of the Fine Arts. I omit Rhetoric, which only respects the form of eloquence and poetry. Architecture and eloquence are mixed arts, whose end is sometimes beauty and sometimes use. It will be seen that in each of these arts there is much which is not spiritual. Each has a material basis, and in each the creating intellect is crippled in some degree by the stuff on which it works. The basis of poetry is language, which is material only on one side. It is a demi-god. But being applied primarily to the common necessities of man, it is not new-created by the poet for his own ends.
