This service is indeed equivalent to a heavy tax; yet is it less felt by a people addicted to arms, who fight for honour and revenge more than pay, and are unacquainted with gain and industry as well as pleasure. Not to mention the great equality of fortunes among the inhabitants of the ancient republics, where every field, belonging to a different proprietor, was able to maintain a family, and rendered the numbers of citizens very considerable, even without trade and manufactures.
But though the want of trade and manufactures, among a free and very martial people, may sometimes have no other effect than to render the public more powerful, it is certain, that, in the common course of human affairs, it will have a quite contrary tendency. Sovereigns must take mankind as they find them, and cannot pretend to introduce any violent change in their principles and ways of thinking. A long course of time, with a variety of accidents and circumstances, are requisite to produce those great revolutions, which so much diversify the face of human affairs. And the less natural any set of principles are, which support a particular society, the more difficulty will a legislator meet with in raising and cultivating them. It is his best policy to comply with the common bent of mankind, and give it all the improvements of which it is susceptible. Now, according to the most natural course of things, industry and arts and trade encrease the power of the sovereign as well as the happiness of the subjects; and that policy is violent, which aggrandizes the public by the poverty of individuals. This will easily appear from a few considerations, which will present to us the consequences of sloth and barbarity.
Where manufactures and mechanic arts are not cultivated, the bulk of the people must apply themselves to agriculture; and if their skill and industry encrease, there must arise a great superfluity from their labour beyond what suffices to maintain them. They have no temptation, therefore, to encrease their skill and industry; since they cannot exchange that superfluity for any commodities, which may serve either to their pleasure or vanity.
A habit of indolence naturally prevails. The greater part of the land lies uncultivated. What is cultivated, yields not its utmost for want of skill and assiduity in the farmers. If at any time the public exigencies require, that great numbers should be employed in the public service, the labour of the people furnishes now no superfluities, by which these numbers can be maintained. The labourers cannot encrease their skill and industry on a sudden. Lands uncultivated cannot be brought into tillage for some years. The armies, mean while, must either make sudden and violent conquests, or disband for want of subsistence.
A regular attack or defence, therefore, is not to be expected from such a people, and their soldiers must be as ignorant and unskilful as their farmers and manufacturers.
Every thing 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 manufactures 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 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 abstractedly, manufactures encrease 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 in it.
