Consider the uses of the body. It is God's schoolmaster teaching industry, compelling economy and thrift, and promoting all the basal moralities. It contains the springs of all material civilization. If we go back to the dawn of history we find that hunger and the desires, associated with the body, have been the chief stimulants toward industrial progress. Indolence is stagnation. Savages in the tropics are torpid and without progress. Hunger compels men to ask what food is in the river, what roots are in the ground, what fruits are on the trees, what forces are in the air. The body is peremptory in its demands. Hunger carries a stinging scourge. Necessity drives out the evil spirits of indolence and torpidity. The early man threading the thickets in search of food chanced upon a sweet plum, and because the bush grew a long way from his lodge he transplanted the root to a vale near his home. Thence came all man's orchards and vineyards. Shivering with cold, man sought out some sheltered cave or hollow tree. But soon the body asked him to hew out a second cave in addition to the one nature had provided. Fulfilling its requests, man went on in the interests of his body to pile stone on stone, and lift up carved pillars and groined arches. Thence came all homes. For the body the sower goes forth to sow, and the harvester looks forward to the time of sheaves and shoutings. For strengthening the body the shepherd leads forth his flocks and herds, and for its raiment the weaver makes the looms and spindles fly. For the body all the trains go speeding in and out, bringing fruits from the sunny south, and furs from the frozen north. All the lower virtues and integrities spring from its desires. As an engine, lying loose in a great ship, would have no value, but, fastened down with bolts, drives the great hull through the water, so the body fastens and bolts the spirit to field, forest, and city, and makes it useful and productive. Material life and civilization may be said to literally rest upon man's bones and sinews.
