That is true; but it will he worn out by the hand and for the profit of the borrower. The latter has taken into account this gradual wear, and taken upon himself, as he ought, the consequences. He has reckoned that he shall derive from this tool an advantage, which will allow him to restore it in its original condition, after having realised a profit from it. As long as James does not use this capital himself, or for his own advantage—as long as he renounces the advantages which allow it to be restored to its original condition—he will have an incontestable right to have it restored, and that independently of interest.
Observe, besides, that if, as I believe I have shown, James, far from doing any harm to William, has done him a service in lending him his plane for a year; for the same reason, he will do no harm to a second, a third, a fourth borrower, in the subsequent periods. Hence you may understand that the interest of a capital is as natural, as lawful, as useful, in the thousandth year, as in the first. We may go still further. It may happen that James lends more than a single plane. It is possible, that by means of working, of saving, of privations, of order, of activity, he may come to lend a multitude of planes and saws; that is to say, to do a multitude of services. I insist upon this point,—that if the first loan has been a social good, it will be the same with all the others; for they
