known; and it is just equally possible, that the most fertile mine then known may be more barren than any that was wrought before the discovery of the mines of America. Whether the one or the other of those two events may happen to take place, is of very little importance to the real wealth and prosperity of the world, to the real value of the annual produce of the land and labour of mankind. Its nominal value, the quantity of gold and silver by which this annual produce could be expressed or represented, would, no doubt, be very different; but its real value, the real quantity of labour which it could purchase or command, would be precisely the same. A shilling might, in the one case, represent no more labour than a penny does at present; and a penny, in the other, might represent as much as a shilling does now. But in the one case, he who had a shilling in his pocket would be no richer than he who has a penny at present; and in the other, he who had a penny would be just as rich as he who has a shilling now. The cheapness and abundance of gold and silver plate would be the sole advantage which the world could derive from the one event; and the dearness and scarcity of those trifling superfluities, the only inconveniency it could suffer from the other.
Conclusion of the Digression concerning the Variations in the Value of Silver.
The greater part of the writers who have collected the money price 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
