The greater part of the writers who have collected the money prices of things in ancient times seem to have considered the low money-price of corn, and of goods in general, or, in other words, the high value of gold and silver, as a proof, not only of the scarcity of those metals, but of the poverty and barbarism of the country at the time when it took place.This notion is connected with the system of political economy which represents national wealth as consisting in the abundance, and national poverty in the scarcity of gold and silver; a system which I shall endeavour to explain and examine at great length in the fourth book of this inquiry.I shall only observe at present that the high value of the precious metals can be no proof of the poverty or barbarism of any particular country at the time when it took place.It is a proof only of the barrenness of the mines which happened at that time to supply the commercial world.A poor country, as it cannot afford to buy more, so it can as little afford to pay dearer for gold and silver than a rich one; and the value of those metals, therefore, is not likely to be higher in the former than in the latter.In China, a country much richer than any part of Europe, the value of the precious metals is much higher than in any part of Europe.As the wealth of Europe, indeed, has increased greatly since the discovery of the mines of America, so the value of gold and silver has gradually diminished.This diminution of their value, however, has not been owing to the increase of the real wealth of Europe, of the annual produce of its land and labour, but to the accidental discovery of more abundant mines than any that were known before.The increase of the quantity of gold and silver in Europe, and the increase of its manufactures and agriculture, are two events which, though they have happened nearly about the same time, yet have arisen from very different causes, and have scarce any natural connection with one another.
The one has arisen from a mere accident, in which neither prudence nor policy either had or could have any share.The other from the fall of the feudal system, and from the establishment of a government which afforded to industry the only encouragement which it requires, some tolerable security that it shall enjoy the fruits of its own labour.Poland, where the feudal system still continues to take place, is at this day as beggarly a country as it was before the discovery of America.The money price of corn, however, has risen; the real value of the precious metals has fallen in Poland, in the same manner as in other parts of Europe.Their quantity, therefore, must have increased there as in other places, and nearly in the same proportion to the annual produce of its land and labour.This increase of the quantity of those metals, however, has not, it seems, increased that annual produce, has neither improved the manufactures and agriculture of the country, nor mended the circumstances of its inhabitants.Spain and Portugal, the countries which possess the mines, are, after Poland, perhaps, the two most beggarly countries in Europe.The value of the precious metals, however, must be lower in Spain and Portugal than in any other part of Europe; as they come from those countries to all other parts of Europe, loaded, not only with a freight and an insurance, but with the expense of smuggling, their exportation being either prohibited, or subjected to a duty.In proportion to the annual produce of the land and labour, therefore, their quantity must be greater in those countries than in any other part of Europe.
Those countries, however, are poorer than the greater part of Europe.Though the feudal system has been abolished in Spain and Portugal, it has not been succeeded by a much better.
As the low value of gold and silver, therefore, is no proof of the wealth and flourishing state of the country where it takes place; so neither is their high value, or the low money price either of goods in general, or of corn in particular, any proof of its poverty and barbarism.
But though the low money price either of goods in general, or of corn in particular, be no proof of the poverty or barbarism of the times, the low money price of some particular sorts of goods, such as cattle, poultry, game of all kinds, etc., in proportion to that of corn, is a most decisive one.It clearly demonstrates, first, their great abundance in proportion to that of corn, and consequently the great extent of the land which they occupied in proportion to what was occupied by corn; and, secondly, the low value of this land in proportion to that of corn land, and consequently the uncultivated and unimproved state of the far greater part of the lands of the country.It clearly demonstrates that the stock and population of the country did not bear the same proportion to the extent of its territory which they commonly do in civilised countries, and that society was at that time, and in that country, but in its infancy.From the high or low money price either of goods in general, or of corn in particular, we can infer only that the mines which at that time happened to supply the commercial world with gold and silver were fertile or barren, not that the country was rich or poor.But from the high or low money price of some sorts of goods in proportion to that of others, we can infer, with a degree of probability that approaches almost to certainty, that it was rich or poor, that the greater part of its lands were improved or unimproved, and that it was either in a more or less barbarous state, or in a more or less civilised one.
