Oresme on Money, AD 1375
"Some men hold that any king or prince may, of his own authority, by right or prerogative, freely alter the money current in his realm, regulate it as he will, and take whatever gain or profit may result: but other men are of the contrary opinion. I have therefore determined to write down in this treatise what seems to me from a philosophical and Aristotelian point of view, essentially proper to be said, beginning with the origin of money."I make no rash assertions, but submit everything to the judgment of my seniors. Perhaps my words will rouse them finally to settle the truth of this matter, so that the experts may all be of one mind, and come to a conclusion which shall be profitable both to princes and subjects, and indeed to the state as a whole."
"[Altering the value of the currency] does not avoid scandal, but begets it...and it has many awkward consequences,...Nor is there any necessity or convenience in doing it, nor can it advantage the commonwealth. A clear sign of this is that such alterations are a modern invention, as was mentioned in the last chapter. For such a thing was never done in cities or kingdoms formerly or now well governed....If the Italians or Romans did in the end make such alterations, as appears from ancient bad money sometimes to be found in the country, this was probably the reason why their noble empire came to nothing. It appears therefore that these changes are so bad that they are essentially impermissible."
"As time goes on and changes [in the value of money] proceed, it often happens that nobody knows what a particular coin is worth, and money has to be dealt in, bought and sold, or changed from its value, a thing which is against its nature. And so there is no certainty in a thing in which certainty is of the highest importance, but rather uncertain and disordered confusion, to the prince's reproach. Also it is absurd and repugnant to the royal dignity to prohibit the currency of the true and good money of the realm, and from motives of greed to command, or rather compel, subjects to use less good money; which amounts to saying that good is evil and vice versa."
"Some sections of the community are occupied in affairs honourable or profitable to the whole state, as in the growing of natural wealth or negotiating on behalf of the community. Such are churchmen, judges, soldiers, husbandmen, merchants, craftsmen and the like. But another section augments its own wealth by unworthy business, as do money-changers, bankers or dealers in bullion: a disgraceful trade as was said in Chapter XVIII. These men, then, who are as it were unwanted by the state, and some others such as receivers and financial agents, etc., take a great part of the profit or gain arising from changes in coinage and by guile or by good luck, draw wealth from them, against God and Justice, since they are undeserving of such riches and unworthy of such wealth. But others, who are the best sections of the community, are impoverished by it; so that the prince in this way damages and overburdens the larger and better part of his subjects and yet does not receive the whole of the profit; but the persons abovementioned, whose business is contemptible and largely fraudulent, get a large part of it."
