Everything in the world is purchased by labour, and our passions are the only causes of labour. When a nation abounds in manufactures and mechanic arts, the proprietors of land, as well as the farmers, study agriculture as a science, and redouble their industry and attention. The superfluity which arises from their labour is not lost, but is exchanged with the manufacturers for those commodities which men’s luxury now makes them covet. By this means land furnishes a great deal more of the necessaries of life than what suffices for those who cultivate it. In times of peace and tranquillity this superfluity goes to the maintenance of manufacturers, and the improvers of liberal arts. But it is easy for the public to convert many of these manufacturers into soldiers, and maintain them by that superfluity which arises from the labour of the farmers. Accordingly we find that this is the case in all civilized governments. When the sovereign raises an army, what is the consequence? He imposes a tax. This tax obliges all the people to retrench what is least necessary to their {p9} subsistence. Those who labour in such commodities must either enlist in the troops or turn themselves to agriculture, and thereby oblige some labourers to enlist for want of business. And to consider the matter abstractly, manufactures increase the power of the state only as they store up so much labour, and that of a kind to which the public may lay claim, without depriving any one of the necessaries of life. The more labour, therefore, is employed beyond mere necessaries, the more powerful is any state; since the persons engaged in that labour may easily be converted to the public service. In a state without manufactures there may be the same number of hands; but there is not the same quantity of labour, nor of the same kind. All the labour is there bestowed upon necessaries, which can admit of little or no abatement.
Thus the greatness of the sovereign and the happiness of the state are, in a great measure, united with regard to trade and manufactures. It is a violent method, and in most cases impracticable, to oblige the labourer to toil in order to raise from the land more than what subsists himself and family. Furnish him with manufactures and commodities, and he will do it of himself. Afterwards you will find it easy to seize some part of his superfluous labour, and employ it in the public service, without giving him his wonted return. Being accustomed to industry, he will think this less grievous than if, at once, you obliged him to an augmentation of labour without any reward. The case is the same with regard to the other members of the state. The greater is the stock of labour of all kinds, the greater quantity may be taken from the heap without making any sensible alteration upon it.
A public granary of corn, a storehouse of cloth, a magazine of arms; all these must be allowed real riches and strength in any state. Trade and industry are really nothing but a stock of labour, which, in time of peace and tranquillity, is employed for the ease and satisfaction of individuals; but in the exigencies of state, may, in part, be turned to public advantage. Could we convert a city into a kind of fortified {p10} camp, and infuse into each breast so martial a genius, and such a passion for public good, as to make every one willing to undergo the greatest hardships for the sake of the public, these affections might now, as in ancient times, prove alone a sufficient spur to industry, and support the community. It would then be advantageous, as in camps, to banish all arts and luxury; and, by restrictions on equipage and tables, make the provisions and forage last longer than if the army were loaded with a number of superfluous retainers. But as these principles are too disinterested and too difficult to support, it is requisite to govern men by other passions, and animate them with a spirit of avarice and industry, art and luxury. The camp is, in this case, loaded with a superfluous retinue; but the provisions flow in proportionately larger. The harmony of the whole is still supported, and the natural bent of the mind being more complied with, individuals, as well as the public, find their account in the observance of those maxims.
The same method of reasoning will let us see the advantage of foreign commerce, in augmenting the power of the state, as well as the riches and happiness of the subjects. It increases the stock of labour in the nation, and the sovereign may convert what share of it he finds necessary to the service of the public. Foreign trade, by its imports, furnishes materials for new manufactures; and by its exports, it produces labour in particular commodities which could not be consumed at home. In short, a kingdom that has a large import and export must abound more with industry, and that employed upon delicacies and luxuries, than a kingdom which rests contented with its native commodities. It is, therefore, more powerful, as well as richer and happier. The individuals reap the benefit of these commodities, so far as they gratify the senses and appetites. And the public is also a gainer, while a greater stock of labour is, by this means, stored up against any public exigency; that is, a greater number of laborious men are maintained, who may be diverted to the public service {p11} without robbing any one of the necessaries or even the chief conveniences of life.
If we consult history, we shall find that in most nations foreign trade has preceded any refinement in home manufactures, and given birth to domestic luxury. The temptation is stronger to make use of foreign commodities, which are ready for use, and which are entirely new to us, than to make improvements on any domestic commodity, which always advance by slow degrees, and never affect us by their novelty. The profit is also very great in exporting what is superfluous at home, and what bears no price, to foreign nations, whose soil or climate is not favourable to that commodity. Thus men become acquainted with the pleasures of luxury and the profits of commerce; and their delicacy and industry, being once awakened, carry them to farther improvements in every branch of domestic as well as foreign trade. And this perhaps is the chief advantage which arises from a commerce with strangers. It rouses men from their indolence; and presenting the gayer and more opulent part of the nation with objects of luxury, which they never before dreamed of, raises in them a desire of a more splendid way of life than what their ancestors enjoyed; and at the same time the few merchants who possess the secret of this importation and exportation make exorbitant profits, and becoming rivals in wealth to the ancient nobility, tempt other adventurers to become their rivals in commerce. Imitation soon diffuses all those arts; while domestic manufacturers emulate the foreign in their improvements, and work up every home commodity to the utmost perfection of which it is susceptible. Their own steel and iron, in such laborious hands, becomes equal to the gold and rubies of the Indies.
When the affairs of the society are once brought to this situation, a nation may lose most of its foreign trade, and yet continue a great and powerful people. If strangers will not take any particular commodity of ours, we must cease to labour in it. The same hands will turn themselves towards some refinement in other commodities which may be {p12} wanted at home. And there must always be materials for them to work upon; till every person in the state, who possesses riches, enjoys as great plenty of home commodities, and those in as great perfection, as he desires; which can never possibly happen. China is represented as one of the most flourishing empires in the world, though it has very little commerce beyond its own territories.
It will not, I hope, be considered as a superfluous digression, if I here observe, that as the multitude of mechanical arts is advantageous, so is the great number of persons to whose share the productions of these arts fall. A too great disproportion among the citizens weakens any state. Every person, if possible, ought to enjoy the fruits of his labour, in a full possession of all the necessaries, and many of the conveniences of life. No one can doubt but such an equality is most suitable to human nature, and diminishes much less from the happiness of the rich than it adds to that of the poor. It also augments the power of the state, and makes any extraordinary taxes or
