““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.””
