In the middle centuries, when a mistaken zeal animated christianity with a most ungodly thirst for the blood of infidels, the Jews were, in every nation in Europe, almost the only money lenders. This circumstance still more engaged the church to dart her thunder against this practice; and the loan upon interest never took root among christians, until a spirit of trade and industry sprung up in Italy in the time of the Lombards, and spread itself through the channel of the Hans-towns over several nations. Then the church began to open her eyes, and saw the expediency of introducing many modifications, to limit the general anathema against the whole class of money lenders. At one time it was declared lawful to lend at interest, when the capital shared any risque in the hands of the borrower; at another, it was found allowable; when the capital was not demandable from the debtor, while he paid the interest: again, it was permitted, when the debtor was declared by sentence of a judge, to be _in mora_ in acquitting his obligation: at last, it was permitted on bills of exchange. In short, in most Roman catholic countries, interest is now permitted in every case almost, except in obligations bearing a stipulation of interest for sums demandable at any time after the term of payment; and it is as yet no where considered as essential to loan, or demandable upon obligations payable on demand. Expediency and the good of society (politically speaking) are the only rule for judging, when the loan upon interest should be permitted, when forbid. While people borrowed only in order to procure a circulating equivalent for providing their necessaries, until they could have time to dispose of their effects; and while there was seldom any certain profit to be made by the use of the money borrowed, by turning it into trade, it was very natural to consider the lender in an unfavourable light; because it was supposed that the money, if not lent, must have remained locked up in his coffers. But at present, when we see so many people employed in providing stores of necessaries for others, which, without money, could not be done; forbidding the loan upon interest, has the effect of locking up the very instrument (money) which is necessary for supplying the wants of the society. The loan, therefore, upon interest, _as society now stands composed_, is established, not in favour of the lenders, but of the whole community; and taking the matter in this light, no one, I suppose, will pretend that what is beneficial to a whole society should be forbid, because of its being proportionably advantageous to some particular members of it.
