The Casuists, who seem hardly suitable people to judge the nature of interest and of matters of trade, have invented a term, damnum emergens, by whose aid they consent to tolerate these high rates of interest; and rather than upset the custom and convenience of society, they have agreed and allowed to those who lend at great risk to exact in proportion a high rate of interest: and this without limit, for they would be hard put to it to find any certain limit since the business depends in reality on the fears of the lenders and the needs of the borrowers.
Maritime merchants are praised when they can make a profit on their Adventures, even though it be 10,000 per cent; and whatever profit wholesale merchants may make or stipulate for in Selling on long credit produce or merchandise to smaller retail merchants, I have not heard that the Casuists make it a crime.
They are or seem to be a little more scrupulous about loans in hard cash though it is essentially the same thing. Yet they tolerate even these loans by a distinction, lucrum cessans, which they have invented. I understand this to mean that a man who has been in the habit of ****** his money bring in 500 per cent in his trade may demand this profit when he lends it to another.
Nothing is more amusing than the multitude of laws and canons made in every age on the subject of the interest of money, always by wiseacres who were hardly acquainted with trade and always without effect.
From these examples and inductions it seems that there are in a state many classes and channels of interest or profit, that in the lowest classes interest is always highest in proportion to the greater risk, and that it diminishes from class to class up to the highest which is that of merchants who are rich and reputed solvent. The interest demanded in this class is called the current rate of interest in the state and differs little from interest on the mortgage of land. The bill of a solvent and solid merchant is as much esteemed, at least for a short date, as a lien upon land, because the possibility of a lawsuit or a dispute on this last makes up for the possibility of the bankruptcy of the merchant.
If there were in a state no Undertakers who could make a profit on the money or goods which they borrow, the use of interest would probably be less frequent than it is. Only extravagant and prodigal people would contract loans. But accustomed as every one is to make use of Undertakers there is a constant source for Loans and therefore for interest. They are the Undertakers who cultivate the land and supply bread, meat, clothes, etc. to all the inhabitants of a city. Those who work on wages for these Undertakers seek also to set themselves up as Undertakers, in emulation of each other. The multitude of Undertakers is much greater among the Chinese, and as they all have lively intelligence, a genius for enterprise, and great perseverance in carrying it out, there are among them many Undertakers who are among us people on fixed wages. They supply labourers with meals, even in the fields. It is perhaps this multitude of small Undertakers and others, from class to class, who finding the means to gain a good deal by ministering to consumption without its being felt by the consumers, keep up the rate of interest in the highest class at 30 per cent while it hardly exceeds 5 per cent in our Europe. At Athens in the time of Solon interest was at 18 per cent. In the Roman Republic it was most commonly 12 per cent, but has been known to be 48, 20, 8, 6, and at the lowest 4 per cent. It was never so low in the free market as towards the end of the Republic and under Augustus after the conquest of Egypt. The Emperor Antoninus and Alexander Severus only reduced interest to 4 per cent by lending public money on the mortgage of land.
