0Copernicus - on minting of money

Copernicus commenced a study composed for the Prussian and Polish governments around 1525, On the Minting of Money, with these words:

ALTHOUGH THERE ARE COUNTLESS MALADIES that are forever causing the decline of kingdoms, princedoms, and republics, the following four (in my judgment) are the most serious: civil discord, a high death rate, sterility of the soil, and the debasement of coinage. The first three are so obvious that everybody recognizes the damage they cause; but the fourth one, which has to do with money, is noticed by only a few very thoughtful people, since it does not operate all at once and at a single blow, but gradually overthrows governments, and in a hidden, insidious way.
