Reasonable interest varies with the state of trade and the quantity of coin. In a newly settled country great profits are made by small sums, and land is worth fewer years’ purchase, so that a higher interest is reasonable. Laws in settling interest must follow “these natural causes,” otherwise they will be evaded.76
In the chapter “Of the Nature of Civil Laws and their Execution,” we find that after piety the virtues most necessary to a state are sobriety, industry, justice and fortitude.
“Industry is the natural mine of wealth, the fund of all stores for exportation by the surplus of which beyond the value of what a nation imports, it must increase in wealth and power. Diligent agriculture must furnish the necessaries of life and the materials for all manufactures; and all mechanic arts should be encouraged to prepare them for use and exportation. Goods prepared for export should generally be free from all burdens and taxes, and so should the goods be which are necessarily consumed by the artificers, as much as possible; that no other country be able to undersell like goods at a foreign market. Where one country alone has certain materials, they may safely impose duties upon them when exported; but such moderate ones as shall not prevent the consumption of them abroad.
“If people have not acquired an habit of industry, the cheapness of all the necessaries of life rather encourages sloth. The best remedy is to raise the demand for all necessaries; not merely by premiums upon exporting them, which is often useful too; but by increasing the number of people who consume them; and when they are dear, more labour and application will be requisite in all trades and arts to procure them. Industrious foreigners should therefore be invited to us, and all men of industry should live with us unmolested and easy. Encouragement should be given to marriage and to those who rear a numerous offspring to industry. The unmarried should pay higher taxes as they are not at the charge of rearing new subjects to the state. Any foolish notions of meanness in mechanic arts, as if they were unworthy of men of better families, should be borne down, and men of better condition as to birth or fortune engaged to be concerned in such occupations. Sloth should be punished by temporary servitude at least. Foreign materials should be imported and even premiums given, when necessary, that all our own hands may be employed; and that, by exporting them again manufactured, we may obtain from abroad the price of our labours. Foreign manufactures and products ready for consumption should be made dear to the consumer by high duties, if we cannot altogether prohibit the consumption; that they may never be used by the lower and more numerous orders of the people whose consumption would be far greater than those of the few who are wealthy. Navigation, or the carriage of goods foreign or domestic, should be encouraged, as a gainful branch of business surpassing often all the profit made by the merchant. This too is a nursery of fit hands for defence at sea.
“ ’Tis vain to allege that luxury and intemperance are necessary to the wealth of a state as they encourage all labour and manufactures by making a great consumption. It is plain there is no necessary vice in the consuming of the finest products or the wearing of the dearest manufactures by persons whose fortunes can allow it consistently with the duties of life. And what if men grew generally more frugal and abstemious in such things? more of these finer goods could be sent abroad; or if they could not, industry and wealth might be equally promoted by the greater consumption of goods less chargeable: as he who saves by abating of his own expensive splendour could by generous offices to his friends, and by some wise methods of charity to the poor, enable others to live so much better and make greater consumption than was made formerly by the luxury of one. … Unless therefore a nation can be found where all men are already provided with all the necessaries and conveniencies of life abundantly, men may, without any luxury, make the very greatest consumption by plentiful provision for their children, by generosity and liberality to kinsmen and indigent men of worth, and by compassion to the distresses of the poor.”77
Under “Military skill and fortitude” Hutcheson discusses what Adam Smith afterwards placed under “Arms,” and decides in favour of a trained militia.78
In the same chapter he has a section with the marginal title “what taxes or tributes most eligible,” which contains a repudiation of the policy of taxation for revenue only:—
“As to taxes for defraying the public expenses, these are most convenient which are laid on matters of luxury and splendour rather than the necessaries of life; on foreign products and manufactures rather than domestic; and such as can be easily raised without many expensive offices for collecting them. But above all, a just proportion to the wealth of people should be observed in whatever is raised from them, otherways than by duties upon foreign products and manufactures, for such duties are often necessary to encourage industry at home, though there were no public expenses.”79
This proportionment of taxation to wealth he thinks cannot be attained except by means of periodical estimation of the wealth of families, since land taxes unduly oppress landlords in debt and let moneyed men go free, while duties and excises are paid by the consumer, so that “hospitable generous men or such as have numerous families supported genteelly bear the chief burden here, and the solitary sordid miser bears little or no share of it.”80
It is quite clear from all this that Smith was largely influenced by the traditions of his chair in selecting his economic subjects. Dr. Scott draws attention to the curious fact that
