The capital, however, that is acquired to any country by commerce and manufactures, is always a very precarious and uncertain possession, till some part of it has been secured and realized in the cultivation and improvement of its lands. A merchant, it has been said very properly, is not necessarily the citizen of any particular country. It is in a great measure indifferent to him from what place he carries on his trade; and a very trifling disgust will make him remove his capital, and, together with it, all the industry which it supports, from one country to another. No part of it can be said to belong to any particular country, till it has been spread, as it were, over the face of that country, either in buildings, or in the lasting improvement of lands. No vestige now remains of the great wealth said to have been possessed by the greater part of the Hanse Towns, except in the obscure histories of the thirteenth and fourteenth centuries. It is even uncertain where some of them were situated, or to what towns in Europe the Latin names given to some of them belong. But though the misfortunes of Italy, in the end of the fifteenth and beginning of the sixteenth centuries, greatly diminished the commerce and manufactures of the cities of Lombardy and Tuscany, those countries still continue to be among the most populous and best cultivated in Europe. The civil wars of Flanders, and the Spanish government which succeeded them, chased away the great commerce of Antwerp, Ghent, and Bruges. But Flanders still continues to be one of the richest, best cultivated, and most populous provinces of Europe. The ordinary revolutions of war and government easily dry up the sources of that wealth which arises from commerce only. That which arises from the more solid improvements of agriculture is much more durable, and cannot be destroyed but by those more violent convulsions occasioned by the depredations of hostile and barbarous nations continued for a century or two together; such as those that happened for some time before and after the fall of the Roman empire in the western provinces of Europe.
BOOK IV.
OF SYSTEMS OF POLITICAL ECONOMY.
Political economy, considered as a branch of the science of a statesman or legislator, proposes two distinct objects; first, to provide a plentiful revenue or subsistence for the people, or, more properly, to enable them to provide such a revenue or subsistence for themselves; and, secondly, to supply the state or commonwealth with a revenue sufficient for the public services. It proposes to enrich both the people and the sovereign.
The different progress of opulence in different ages and nations, has given occasion to two different systems of political economy, with regard to enriching the people. The one may be called the system of commerce, the other that of agriculture. I shall endeavour to explain both as fully and distinctly as I can, and shall begin with the system of commerce. It is the modern system, and is best understood in our own country and in our own times.
CHAPTER I.
OF THE PRINCIPLE OF THE COMMERCIAL OR MERCANTILE SYSTEM.
That wealth consists in money, or in gold and silver, is a popular notion which naturally arises from the double function of money, as the instrument of commerce, and as the measure of value. In consequence of its being the instrument of commerce, when we have money we can more readily obtain whatever else we have occasion for, than by means of any other commodity. The great affair, we always find, is to get money. When that is obtained, there is no difficulty in making any subsequent purchase. In consequence of its being the measure of value, we estimate that of all other commodities by the quantity of money which they will exchange for. We say of a rich man, that he is worth a great deal, and of a poor man, that he is worth very little money. A frugal man, or a man eager to be rich, is said to love money; and a careless, a generous, or a profuse man, is said to be indifferent about it. To grow rich is to get money; and wealth and money, in short, are, in common language, considered as in every respect synonymous.
A rich country, in the same manner as a rich man, is supposed to be a country abounding in money; and to heap up gold and silver in any country is supposed to be the readiest way to enrich it. For some time after the discovery of America, the first inquiry of the Spaniards, when they arrived upon any unknown coast, used to be, if there was any gold or silver to be found in the neighbourhood? By the information which they received, they judged whether it was worth while to make a settlement there, or if the country was worth the conquering. Plano Carpino, a monk sent ambassador from the king of France to one of the sons of the famous Gengis Khan, says, that the Tartars used frequently to ask him, if there was plenty of sheep and oxen in the kingdom of France? Their inquiry had the same object with that of the Spaniards. They wanted to know if the country was rich enough to be worth the conquering. Among the Tartars, as among all other nations of shepherds, who are generally ignorant of the use of money, cattle are the instruments of commerce and the measures of value. Wealth, therefore, according to them, consisted in cattle, as, according to the Spaniards, it consisted in gold and silver. Of the two, the Tartar notion, perhaps, was the nearest to the truth.
Mr Locke remarks a distinction between money and other moveable goods. All other moveable goods, he says, are of so consumable a nature, that the wealth which consists in them cannot be much depended on; and a nation which abounds in them one year may, without any exportation, but merely by their own waste and extravagance, be in great want of them the next. Money, on the contrary, is a steady friend, which, though it may travel about from hand to hand, yet if it can be kept from going out of the country, is not very liable to be wasted and consumed. Gold and silver, therefore, are, according to him, the must solid and substantial part of the moveable wealth of a nation; and to multiply those metals ought, he thinks, upon that account, to be the great object of its political economy.
Others admit, that if a nation could be separated from all the world, it would be of no consequence how much or how little money circulated in it. The consumable goods, which were circulated by means of this money, would only be exchanged for a greater or a smaller number of pieces; but the real wealth or poverty of the country, they allow, would depend altogether upon the abundance or scarcity of those consumable goods. But it is otherwise, they think, with countries which have connections with foreign nations, and which are obliged to carry on foreign wars, and to maintain fleets and armies in distant countries. This, they say, cannot be done, but by sending abroad money to pay them with; and a nation cannot send much money abroad, unless it has a good deal at home. Every such nation, therefore, must endeavour, in time of peace, to accumulate gold and silver, that when occasion requires, it may have wherewithal to carry on foreign wars.
In consequence of those popular notions, all the different nations of Europe have studied, though to little purpose, every possible means of accumulating gold and silver in their respective countries. Spain and Portugal, the proprietors of the principal mines which supply Europe with those metals, have either prohibited their exportation under the severest penalties, or subjected it to a considerable duty. The like prohibition seems anciently to have made a part of the policy of most other European nations. It is even to be found, where we should least of all expect to find it, in some old Scotch acts of Parliament, which forbid, under heavy penalties, the carrying gold or silver forth of the kingdom. The like policy anciently took place both in France and England.
When those countries became commercial, the merchants found this prohibition, upon many occasions, extremely inconvenient. They could frequently buy more advantageously with gold and silver, than with any other commodity, the foreign goods which they wanted, either to import into their own, or to carry to some other foreign country. They remonstrated, therefore, against this prohibition as hurtful to trade.
They represented, first, that the exportation of gold and silver, in order to purchase foreign goods, did not always diminish the quantity of those metals in the kingdom; that, on the contrary, it might frequently increase the quantity; because, if the consumption of foreign goods was not thereby increased in the country, those goods might be re-exported to foreign countries, and being there sold for a large profit, might bring back much more treasure than was originally sent out to purchase them. Mr Mun compares this operation of foreign trade to the seed-time and harvest of agriculture. “If we only behold,” says he, “the actions of the husbandman in the seed time, when he casteth away much good corn into the ground, we shall account him rather a madman than a husbandman. But when we consider his labours in the harvest, which is the end of his endeavours, we shall find the worth and plentiful increase of his actions.”
