The principles which influence the doctrine of public credit are so few, and so plain, that it is surprising to see how circumstances could possibly involve them in the obscurity into which we find them plunged on many occasions.
For the better clearing the way towards the main object, I shall shew, from experience, and from the progress of public credit in some nations, that the true principles have been overlooked, and confounded so with extraneous objects, as to be entirely lost.
The true method of decyphering, as it were, the complicated operations of statesmen with respect to this branch, is to bring back to their native simplicity such plans of administration, as, from the infinite perplexity of them, make people believe, that the principles which influence this district of science lie so involved, as to require a peculiar force of genius even to comprehend them.
By proceeding in this plain track, and by keeping the principles constantly in view, the most perplexed systems of borrowing, funding, stock-jobbing, coining and re-coining of money, changing the weight, fineness, and denominations of specie, circulating paper in conjunction with it, imposing upon mankind with bubbles and bankruptcies, and calling them operations of public credit, may be rendred intelligible to the most slender capacity.
Many of these topics have been already explained, and dismissed. This will enable us to contract the plan of what remains in proportion to the objects it is to comprehend.
Public credit we have defined to be, the confidence reposed in a state, or body politic, borrowing money, on condition that the capital shall not be demandable, but that a certain proportional part of the sum shall be annually paid, either in lieu of interest, or in extinction of part of the capital; for the security of which payment, a permanent annual fund is appropriated, with a liberty, however, to the state to set itself free, by repaying the whole, when nothing to the contrary is stipulated.
In this definition I have put in an alternative, of paying a perpetual interest for the money borrowed, or of paying annually a sum exceeding the interest; which excess is intended to extinguish the capital in a certain number of years. In both cases, the annual payment is called an annuity. When it is exactly equal to the interest agreed on, it is called perpetual; and determinate, when granted either for life, or for a certain number of years.
The solidity of this security is essential to the borrowing upon the cheapest terms: let me suppose it to be as solid as land-property, and as permanent as government itself: what will the consequence be?
If we suppose government to go on in increasing, every year, the sum of their debts upon perpetual annuities, and appropriating, in proportion, every branch of revenue for the payment of them; the consequence will be, in the first place, to transport, in favour of the creditors, the whole income of the state, of which government will retain the administration. The farther consequences of this revolution will furnish matter for a chapter by itself.
If the borrowings of a state be only in proportion to the extinction of the old capitals, or of what I have called determinate annuities, then the debts will not increase.
