In the first and second questions, I endeavour to shew, that the quantity of coin in any country, is no sufficient rule for judging of the state of her foreign trade; because money may be acquired and expended by operations nowise mercantile. A nation, may borrow from foreigners more than the amount of the balance against her: she may pay away, in subsidies, and foreign wars, sums greatly beyond the value of a right balance on her trade. She may call in her specie, and trade with it abroad, while paper is made to circulate in its place at home: or she may lock it up in banks, where it never may appear. In short, the riches of a trading nation may resemble those of a trading man; who may be immensely rich, with very little specie in his possession.

On the other hand, the riches of a prodigal nation may resemble those of a prodigal man; who may be full of money, borrowed from all hands, upon the credit of a large fund of solid property.

The third question concerns the effects of riches in those countries where trade and industry are little known. Under such circumstances, coin must be locked up, or virtue will go to wreck. Why? Because, if coin circulate where there is no industry, it must circulate for no adequate equivalent in work or service; that is, for the gratification of the passions, or in monstrous prodigality. Experience demonstrated the truth of this principle. While the Greek Monarchs of Asia and Ægypt remained in possession of their vast treasures, virtue and simplicity stood their ground; when those riches were thrown into circulation, under the first Roman Emperors, we see the horrible consequences which ensued. What could produce such monsters, except a taste of dissipation, without rational objects to discharge their wealth upon? All the money in the universe, thrown into the hands of an extravagant modern Prince, would not affect his morals; the taste of luxury would soon discharge him of it; and the consequence would be, to enrich those who gratified his desires, and that nearly in proportion to their service. But in antient times, the violence of government stopped the progress of industry: the consequence of which was, that the few productions of it were sold for the most exorbitant prices, and the wealth accumulated by private people commonly occasioned their destruction; because rapine was the only expedient Princes had fallen upon to draw back money into their coffers.

Comparing the antient with our modern œconomy, I find both are curious and entertaining. A contrast often makes us reflect upon circumstances which otherwise might escape our observation.

In the fourth and fifth questions, I apply the principles we have laid down, in order to discover why the establishment of trade and industry has naturally given rise to an established system of taxation, and regular standing armies.

This leads me to compare circumstances relative to the œconomy of Europe some centuries ago, when taxes were almost unknown, with the present times, when they are becoming daily more familiar; and I shew that they are, in a great part, paid in lieu of the personal service to which the subjects were formerly bound, and by the means of which states were supported; and if they are extended beyond this proportion, it is in consequence of a new circulation opened between the state and those who serve it: so that the effect of taxes, spent within a country well governed, is to draw money gratuitously from those who have a superfluity of it, in order to bestow it upon those who are willing and capable to advance the service of the state; that is, in other words, to oblige private people to lay out their money for the service of their country.

From the same principles, and from a very succinct historical deduction of the facts relating to the state of the militia of Europe, from the time of the Romans, I endeavour to shew, that standing armies in our days are become necessary, while Princes have the rage of making war; because, without keeping up such bodies of men in time of peace, the call of the luxurious would provide employment for them, which they would not choose to quit, when the will of their sovereign might command their attendance.

These questions lead me to inquire[inquire] into the method of estimating the relative power of different states in making war.

Here I reduce power to the two principles of men and money; the men at the command of a state, are those who have a poor and precarious living, or at least a worse condition than that which the state can offer for their military service; consequently, the more a people are usefully employed, the less they are calculated for filling armies. From hence it is that luxury is said to render a nation effeminate: a true proposition, when rightly understood, relatively to the industrious, not to the luxurious classes of the people.

The annual revenue of a state is in proportion to the circulation; because it is at the time of circulation only that national contributions can be levied with the fewest inconveniencies. Money which does not circulate is of no use to the proprietors, and consequently can be of no utility to the state.
