This apparatus of wants and faculties, this craving body, whose organs ask all the elements and all the functions of Nature for their satisfaction, educate the wondrous creature which they satisfy with light, with heat, with water, with wood, with bread, with wool. The necessities imposed by this most irritable and all-related texture have taught Man hunting, pasturage, agriculture, commerce, weaving, joining, masonry, geometry, astronomy. Here is a world pierced and belted with natural laws, and fenced and planted with civil partitions and properties, which all put new restraints on the young inhabitant. He too must come into this magic circle of relations, and know health and sickness, the fear of injury, the desire of external good, the charm of riches, the charm of power. The household is a school of power. There, within the door, learn the tragi-comedy of human life. Here is the sincere thing, the wondrous composition for which day and night go round. In that routine are the sacred relations, the passions that bind and sever. Here is poverty and all the wisdom its hated necessities can teach, here labor drudges, here affections glow, here the secrets of character are told, the guards of man, the guards of woman, the compensations which, like angels of justice, pay every debt: the opium of custom, whereof all drink and many go mad. Here is Economy, and Glee, and Hospitality, and Ceremony, and Frankness, and Calamity, and Death and Hope. Every one has a trust of power,--every man, every boy a jurisdiction, whether it be over a cow or a rood of a potato-field, or a fleet of ships, or the laws of a state. And what activity the desire of power inspires! What toils it sustains! How it sharpens the perceptions and stores the memory with facts. Thus a man may well spend many years of life in trade. It is a constant teaching of the laws of matter and of mind. No dollar of property can be created without some direct communication with nature, and of course some acquisition of knowledge and practical force. It is a constant contest with the active faculties of men, a study of the issues of one and another course of action, an accumulation of power, and, if the higher faculties of the individual be from time to time quickened, he will gain wisdom and virtue from his business.
