15 - Of money

Summary

Money is not, properly speaking, one of the subjects of commerce; but only the instrument which men have agreed upon to facilitate the exchange of one commodity for another. It is none of the wheels of trade: It is the oil which renders the motion of the wheels more smooth and easy. If we consider any one kingdom by itself, it is evident, that the greater or less plenty of money is of no consequence; since the prices of commodities are always proportioned to the plenty of money, and a crown in Harry VII.'s time served the same purpose as a pound does at present. It is only the public which draws any advantage from the greater plenty of money; and that only in its wars and negociations with foreign states. And this is the reason, why all rich and trading countries, from Carthage to Britain and Holland, have employed mercenary troops, which they hired from their poorer neighbours. Were they to make use of their native subjects, they would find less advantage from their superior riches, and from their great plenty of gold and silver; since the pay of all their servants must rise in proportion to the public opulence. Our small army in Britain of 20,000 men is maintained at as great expence as a French army twice as numerous. The English fleet, during the late war, required as much money to support it as all the Roman legions, which kept the whole world in subjection, during the time of the emperors.
