The aspect of industrial life altered. The domestic industry of the cottage and the individual labor of the artisan gave place to the factory with its regiment of workers and its steam-driven machinery. The economic isolation of the single worker, of the village, even of the district and the nation, was lost in the general cohesion in which the whole industrial world merged into one. The life of the individual changed accordingly. In the old world his little sphere was allotted to him and there he stayed. His village was his horizon. The son of the weaver wove and the smith reared his children to his trade. Each did his duty, or was adjured to do it, in the "state of life to which it had pleased God to call him." Migration to distant occupations or to foreign lands was but for the adventurous few. The ne'er-do-well blew, like seed before the wind, to distant places, but mankind at large stayed at home. Here and there exceptional industry or extraordinary capacity raised the artisan to wealth and turned the "man" into the "master." But for the most part even industry and endowment were powerless against the inertia of custom and the dead-weight of environment. The universal ignorance of the working class broke down the aspiring force of genius. Mute inglorious Miltons were buried in country churchyards. In the new world all this changed. The individual became but a shifting atom in the vast complex, moving from place to place, from occupation to occupation and from gradation to gradation of material fortune. The process went further and further. The machine penetrated everywhere, thrusting aside with its gigantic arm the feeble efforts of handicraft. It laid its hold upon agriculture, sowing and reaping the grain and transporting it to the ends of the earth. Then as the nineteenth century drew towards its close, even the age of steam power was made commonplace by achievements of the era of electricity. All this is familiar enough. The record of the age of machinery is known to all. But the strange mystery, the secret that lies concealed within its organization, is realized by but few. It offers, to those who see it aright, the most perplexing industrial paradox ever presented in the history of mankind. With all our wealth, we are still poor. After a century and a half of labor-saving machinery, we work about as hard as ever. With a power over nature multiplied a hundred fold, nature still conquers us. And more than this. There are many senses in which the machine age seems to leave the great bulk of civilized humanity, the working part of it, worse off instead of better. The nature of our work has changed. No man now makes anything. He makes only a part of something, feeding and tending a machine that moves with relentless monotony in the routine of which both the machine and its tender are only a fractional part.
