F. Yes, it appears so, and it is this I complain of, and not of the reality. A measure of length, size, surface, is a quantity agreed upon, and unchangeable. It is not so with the value of gold and silver. This varies as much as that of corn, wine, cloth, or labour, and from the same causes, for it has the same source and obeys the same laws. Gold is brought within our reach, just like iron, by the labour of miners, the advances of capitalists, and the combination of merchants and seamen. It costs more or less, according to the expense of its production, according to whether there is much or little in the market, and whether it is much or little in request; in a word, it undergoes the fluctuations of all other human productions. But one circumstance is singular, and gives rise to many mistakes. When the value of cash varies, the variation is attributed by language to the other productions for which it is exchanged. Thus, let us suppose that all the circumstances relative to gold remain the same, and that the corn harvest has failed. The price of corn will rise. It will be said, "The quarter of corn, which was worth twenty francs, is now worth thirty;" and this will be correct, for it is the value of the corn which has varied, and language agrees with the fact. But let us reverse the supposition: let us suppose that all the circumstances relative to corn remain the same, and that half of all the gold in existence is swallowed up; this time it is the price of gold which will rise. It would seem that we ought to say,--"This Napoleon, which _was worth_ twenty francs, _is now worth_ forty." Now, do you know how this is expressed? Just as if it was the other objects of comparison which had fallen in price, it is said,--"Corn, which _was worth_ twenty francs, _is now only worth_ ten." B. It all comes to the same thing in the end.
