As mankind multiply and associate together in cities and towns, their attention is directed to other means of procuring the necessaries of life. Trade, manufactures, and commerce offer ample opportunities for the exercise of talent and industry; and the simplicity and contentment of rural life are exchanged for a more artificial state of society. The accumulation of property henceforth becomes an object of general pursuit, and the busy mind of man is occupied in forming and digesting plans to ensure such a result. Should prosperity attend his undertakings, and crown his labours with increase, he will not be slow in acquiring a taste for additional comfort and enjoyment, which his improved circumstances have placed within his reach. Thus the wants of man increase with his means of satisfying them. They are no longer confined to the simple necessaries of life, but embrace those elegancies and luxuries which owe their origin to the increase of wealth, the refinement of education, and the intercourse of society. Surplus capital thus finds ample and ready means of occupation in ministering to the growing wants of the community. Various trades, arts and professions are introduced, which open up new sources of employment; a stimulus is given to industry, and the powers of the mind are brought into operation to diffuse information and instruction through the land. Thus national wealth, education, and refinement advance together; and the riches which found entrance in one direction, find their way, through various channels, to every ramification of society, as the blood which flows from the heart circulates through every part of the human system. So long as surplus wealth thus extends, and promotes a nation’s prosperity, it is legitimately employed. But there are certain limits within which it ought to be confined. The morality, intelligence, and industry of the people are the bulwarks of national greatness; and if, by the introduction of any article of luxury or common diet, these barriers are weakened or thrown down, and the flood-gates of immorality, ignorance, and idleness opened, their dark tide will begin to flow, and threaten the best interests of the country. This result is shown by the histories of all those nations which reached the summit of wealth and power by the exercise of temperance, and whose downfall was hastened by their intemperance, producing idle and licentious habits, discord, effeminacy, and a spirit of dependence. Such were the Persians, the Greeks, and the Romans.
