We may infer, from a comparison of prices, that money is not more

plentiful in China than it was in Europe three centuries ago; but what

immense power is that empire possessed of, if we may judge by the civil

and military list maintained by it! Polybius tells us that provisions

were so cheap in Italy during his time that in some places the

stated club​[16] at the inns was a _semis_ a head, little more than a

farthing! Yet the Roman power had even then subdued the whole known

world. About a century before that period the Carthaginian ambassador

said, by way of raillery, that no people lived more sociably amongst

themselves than the Romans, for that in every entertainment which, as

foreign ministers, they received they still observed the same plate

at every table. The absolute quantity of the precious metals is a

matter of great indifference. There are only two circumstances of any

importance—viz., their gradual increase and their thorough concoction

and circulation through the state; and the influence of both these

circumstances has been here explained.

In the following essay we shall see an instance of a like fallacy as

that above mentioned, where a collateral effect is taken for a cause,

and where a consequence is ascribed to the plenty of money; though it

be really owing to a change in the manners and customs of the people.

NOTES, OF MONEY.

[12] A private soldier in the Roman infantry had a denarius a day,

somewhat less than eightpence. The Roman emperors had commonly 25

legions in pay, which, allowing 5000 men to a legion, makes 125,000.

(Tacitus, _Ann._ lib. 4.) It is true there were also auxiliaries to

the legions, but their numbers are uncertain as well as their pay. To

consider only the legionaries, the pay of the private men could not

exceed £1,600,000. Now, the Parliament in the last war commonly allowed

for the fleet £2,500,000. We have therefore £900,000 over for the

officers and other expenses of the Roman legions. There seem to have

been but few officers in the Roman armies in comparison of what are

employed in all our modern troops, except some Swiss corps. And these

officers had very small pay: a centurion, for instance, only double a

common soldier. And as the soldiers from their pay (Tacitus, _Ann._

lib. 1) bought their own clothes, arms, tents, and baggage, this must

also diminish considerably the other charges of the army. So little

expensive was that mighty Government, and so easy was its yoke over

the world. And, indeed, this is the more natural conclusion from the

foregoing calculations; for money, after the conquest of Egypt, seems

to have been nearly in as great plenty at Rome as it is at present in

the richest of the European kingdoms.

[13] This is the case with the bank of Amsterdam.

[14] These facts I give upon the authority of Monsieur du Tot in his

_Reflexions politiques_, an author of reputation; though I must confess

that the facts which he advances on other occasions are often so

suspicious as to make his authority less in this matter. However, the

general observation that the augmenting the money in France does not at

first proportionably augment the prices is certainly just.

By the by, this seems to be one of the best reasons which can be given

for a gradual and universal augmentation of the money, though it has

been entirely overlooked in all those volumes which have been written

on that question by Melon, Du Tot, and Paris de Verney. Were all our

money, for instance, recoined, and a penny’s worth of silver taken from

every shilling, the new shilling would probably purchase everything

that could have been bought by the old; the prices of everything

would thereby be insensibly diminished; foreign trade enlivened; and

domestic industry, by the circulation of a greater number of pounds and

shillings, would receive some increase and encouragement. In executing

such a project, it would be better to make the new shilling pass for

twenty-four half-pence, in order to preserve the illusion, and make it

be taken for the same. And as a recoinage of our silver begins to be

requisite, by the continual wearing of our shillings and six-pences,

it may be doubtful whether we ought to imitate the example in King

William’s reign, when the clipped money was raised to the old standard.

[15] The Italians gave to the Emperor Maximilian the nickname of

Pochi-Danari. None of the enterprises of that prince ever succeeded,

for want of money.

OF INTEREST.

Nothing is esteemed a more certain sign of the flourishing condition

of any nation than the lowness of interest; and with reason, though

I believe the cause is somewhat different from what is commonly

apprehended. The lowness of interest is generally ascribed to the

plenty of money; but money, however plentiful, has no other effect, if

fixed, than to raise the price of labour. Silver is more common than

gold, and therefore you receive a great quantity of it for the same

commodities. But do you pay less interest for it? Interest in Batavia

and Jamaica is at 10 per cent., in Portugal at 6; though these places,

as we may learn from the prices of everything, abound much more

in gold and silver than either London or Amsterdam.

Were all the gold in England annihilated at once, and one-and-twenty

shillings substituted in the place of every guinea, would money be more

plentiful and interest lower? No surely; we should only use silver

instead of gold. Were gold rendered as common as silver, and silver as

common as copper, would money be more plentiful and interest lower?

We may assuredly give the same answer. Our shillings would then be

yellow, and our halfpence white; and we should have no guineas. No

other difference would ever be observed; no alteration on commerce,

manufactures, navigation, or interest; unless we imagine that the

colour of the metal is of any consequence.

Now, what is so visible in these greater variations of scarcity or

abundance of the precious metals must hold in all inferior changes.

If the multiplying gold and silver fifteen times makes no difference,

much less can the doubling or tripling them. All augmentation has no

other effect than to heighten the price of labour and commodities; and

even this variation is little more than that of a name. In the progress

towards these changes the augmentation may have some influence by

exciting industry; but after the prices are settled, suitable to the

new abundance of gold and silver, it has no manner of influence.

An effect always holds proportion with its cause. Prices have risen

about four times since the discovery of the Indies, and it is probable

that gold and silver have multiplied much more; but interest has not

fallen much above a half. The rate of interest, therefore, is not

derived from the quantity of the precious metals.

Money having merely a fictitious value, arising from the agreement

and convention of men, the greater or less plenty of it is of no

consequence, if we consider a nation within itself; and the quantity

of specie, when once fixed, though never so large, has no other

effect than to oblige every one to tell out a greater number of those

shining bits of metal for clothes, furniture, or equipage, without

increasing any one convenience of life. If a man borrows money

to build a house, he then carries home a greater load; because the

stone, timber, lead, glass, etc., with the labour of the masons and

carpenters, are represented by a greater quantity of gold and silver.

But as these metals are considered merely as representations, there

can no alteration arise from their bulk or quantity, their weight

or colour, either upon their real value or their interest. The same

interest, in all cases, bears the same proportion to the sum. And if

you lent me so much labour and so many commodities, by receiving 5 per

cent. you receive always proportional labour and commodities, however

represented, whether by yellow or white coin, whether by a pound or an

ounce. It is in vain, therefore, to look for the cause of the fall or

rise of interest in the greater or less quantity of gold and silver

which is fixed in any nation.

High interest arises from three circumstances: A great demand for

borrowing; little riches to supply that demand; and great profits

arising from commerce. And these circumstances are a clear proof of the

small advance of commerce and industry, not of the scarcity of gold

and silver. Low interest, on the other hand, proceeds from the three

opposite circumstances: A small demand for borrowing; great riches to

supply that demand; and small profits arising from commerce. And these

circumstances are all connected together, and proceed from the increase

of industry and commerce, not of gold and silver. We shall endeavour

to prove these points as fully and distinctly as possible, and shall

begin with the causes and the effects of a great or small demand for

borrowing.

When the people have emerged ever so little from a savage state, and

their numbers have increased beyond the original multitude, there

must immediately arise an inequality of property; and while some

possess large tracts of land, others are confined within narrow

limits, and some are entirely without any landed property. Those who

possess more land than they can labour employ those who possess none,

and agree to receive a determinate part of the product. Thus

the landed interest is immediately established; nor is there any

settled government, however rude, in which affairs are not on this

footing. Of these proprietors of land, some must presently discover

themselves to be of different tempers from others; and while one would

willingly store up the product of his land for futurity, another

desires to consume at present what should suffice for many years. But

as the spending a settled revenue is a way of life entirely without

occupation, men have so much need of somewhat to fix and engage them,

that pleasures, such as they are, will be the pursuit of the greatest

part of the landholders, and the prodigals amongst them will always

be more numerous than the misers. In a state, therefore, where there

is nothing but a landed interest, as there is little frugality, the

borrowers must be very numerous, and the rate of interest must hold

proportion to it. The difference depends not on the quantity of money,

but on the habits and manners which prevail. By this alone the demand

for borrowing is increased or diminished. Were money so plentiful as

to make an egg be sold for sixpence, so long as there are only landed

gentry and peasants in the state, the borrowers must be numerous and

interest high. The rent for the same farm would be heavier and more

bulky, but the same idleness of the landlord, with the higher prices of

commodities, would dissipate it in the same time, and produce the same

necessity and demand for borrowing.

Nor is the case different with regard to the second circumstance which

we proposed to consider—viz., the great or little riches to supply

this demand. This effect also depends on the habits and ways of living

of the people, not on the quantity of gold and silver. In order to

have in any state a great number of lenders, it is not sufficient nor

requisite that there be great abundance of the precious metals. It is

only requisite that the property or command of that quantity which is

in the state, whether great or small, should be collected in particular

hands, so as to form considerable sums, or compose a great moneyed

interest. This begets a number of lenders and sinks the rate of usury;

and this, I shall venture to affirm, depends not on the quantity

of specie, but on particular manners and customs, which make the specie

gather into separate sums or masses of considerable value.

For suppose that, by miracle, every man in Britain should have five

pounds slipped into his pocket in one night: this would much more than

double the whole money that is at present in the kingdom; and yet there

would not next day, nor for some time, be any more lenders, nor any

variation on the interest. And were there nothing but landlords and

peasants in the state, this money, however abundant, could never gather

into sums; and would only serve to increase the prices of everything,

without any further consequence. The prodigal landlord dissipates it

as fast as he receives it; and the beggarly peasant has no means, nor

view, nor ambition of obtaining above a bare livelihood. The overplus

of borrowers above that of lenders continuing still the same, there

will follow no reduction of interest. That depends upon another

principle, and must proceed from an increase of industry and frugality,

of arts and commerce.

Everything useful to the life of man arises from the ground; but few

things arise in that condition which is requisite to render them

useful. There must, therefore, besides the peasants and the proprietors

of land, be another rank of men, who, receiving from the former the

rude materials, work them into their proper form, and retain part

for their own use and subsistence. In the infancy of society, these

contracts betwixt the artisans and the peasants, and betwixt one

species of artisans and another, are commonly entered into immediately

by the persons themselves, who, being neighbours, are easily acquainted

with each other’s necessities, and can lend their mutual assistance

to supply them. But when men’s industry increases, and their views

enlarge, it is found that the most remote parts of the state can assist

each other as well as the more contiguous, and that this intercourse of

good offices may be carried on to the greatest extent and intricacy.

Hence the origin of merchants, the most useful race of men in the

whole society, who serve as agents between those parts of the

state that are wholly unacquainted and are ignorant of each other’s

necessities. Here are in a city fifty workmen in silk and linen, and a

thousand customers; and these two ranks of men, so necessary to each

other, can never rightly meet till one man erects a shop, to which all

the workmen and all the customers repair. In this province grass rises

in abundance: the inhabitants abound in cheese, and butter, and cattle;

but want bread and corn, which, in a neighbouring province, are in

too great abundance for the use of the inhabitants. One man discovers

this. He brings corn from the one province, and returns with cattle;

and supplying the wants of both, he is, so far, a common benefactor.

As the people increase in numbers and industry, the difficulty of

their intercourse increases: the business of the agency or merchandise

becomes more intricate, and divides, subdivides, compounds, and mixes

to a greater variety. In all these transactions it is necessary, and

reasonable, that a considerable part of the commodities and labour

should belong to the merchant, to whom, in a great measure, they are

owing. And these commodities he will sometimes preserve in kind, or

more commonly convert into money, which is their common representation.

If gold and silver have increased in the state together with the

industry, it will require a great quantity of these metals to represent

a great quantity of commodities and labour; if industry alone has

increased, the prices of everything must sink, and a very small

quantity of specie will serve as a representation.

There is no craving or demand of the human mind more constant and

insatiable than that for exercise and employment, and this desire

seems the foundation of most of our passions and pursuits. Deprive a

man of all business and serious occupation, he runs restless from one

amusement to another; and the weight and oppression which he feels from

idleness is so great that he forgets the ruin which must follow from

his immoderate expenses. Give him a more harmless way of employing his

mind or body, he is satisfied, and feels no longer that insatiable

thirst after pleasure. But if the employment you give him be

profitable, especially if the profit be attached to every particular

exertion of industry, he has gain so often in his eye that he acquires,

by degrees, a passion for it, and knows no such pleasure as that of

seeing the daily increase of his fortune. And this is the reason why

trade increases frugality, and why, among merchants, there is the same

overplus of misers above prodigals as, among the possessors of land,

there is the contrary.

Commerce increases industry, by conveying it readily from one member

of the state to another, and allowing none of it to perish or become

useless. It increases frugality, by giving occupation to men, and

employing them in the arts of gain, which soon engage their affection

and remove all relish for pleasure and expense. It is an infallible

consequence of all industrious professions to beget frugality, and make

the love of gain prevail over the love of pleasure. Among lawyers and

physicians who have any practice there are many more who live within

their income than who exceed it, or even live up to it. But lawyers

and physicians beget no industry, and it is even at the expense of

others they acquire their riches; so that they are sure to diminish the

possessions of some of their fellow-citizens as fast as they increase

their own. Merchants, on the contrary, beget industry, by serving as

canals to convey it through every corner of the state; and at the

same time, by their frugality, they acquire great power over that

industry, and collect a large property in the labour and commodities

which they are the chief instruments in producing. There is no other

profession, therefore, except merchandise, which can make the moneyed

interest considerable, or, in other words, can increase industry, and,

by also increasing frugality, give a great command of that industry to

particular members of the society. Without commerce, the state must

consist chiefly of landed gentry, whose prodigality and expense make a

continual demand for borrowing, and of peasants, who have no sums to

supply that demand. The money never gathers into large stocks or sums

which can be lent at interest. It is dispersed into numberless

hands, who either squander it in idle show and magnificence, or employ

it in the purchase of the common necessaries of life. Commerce alone

assembles it into considerable sums; and this effect it has merely

from the industry which it begets and the frugality which it inspires,

independent of that particular quantity of precious metal which may

circulate in the state.

Thus an increase of commerce, by a necessary consequence, raises a

great number of lenders, and by that means produces a lowness of

interest. We must now consider how far this increase of commerce

diminishes the profits arising from that profession, and gives rise to

the third circumstance requisite to produce a lowness of interest.

It may be proper to observe on this head that low interest and low

profits of merchandise are two events that mutually forward each

other, and are both originally derived from that extensive commerce

which produces opulent merchants and renders the moneyed interest

considerable. Where merchants possess great stocks, whether represented

by few or many pieces of metal, it must frequently happen that when

they either become tired of business or have heirs unwilling or unfit

to engage in commerce, a great deal of these riches will seek an

annual and secure revenue. The plenty diminishes the price, and makes

the lenders accept of a low interest. This consideration obliges

many to keep their stocks in trade, and rather be content with low

profits than dispose of their money at an under value. On the other

hand, when commerce has become very extensive, and employs very large

stocks, there must arise rivalships among the merchants, which diminish

the profits of trade, at the same time that they increase the trade

itself. The low profits of merchandise induce the merchants to accept

more willingly of a low interest, when they leave off business and

begin to indulge themselves in ease and indolence. It is needless,

therefore, to inquire which of these circumstances—viz., low interest

or low profits, is the cause, and which the effect. They both arise

from an extensive commerce, and mutually forward each other. No

man will accept of low profits where he can have high interest, and

no man will accept of low interest where he can have high profits.

An extensive commerce, by producing large stocks, diminishes both

interest and profits; and is always assisted in its diminution of the

one by the proportional sinking of the other. I may add, that as low

profits arise from the increase of commerce and industry, they serve

in their turn to the further increase of commerce, by rendering the

commodities cheaper, encouraging the consumption, and heightening the

industry. And thus, if we consider the whole connection of causes and

effects, interest is the true barometer of the state, and its lowness

is a sign almost infallible of the flourishing of a people. It proves

the increase of industry, and its prompt circulation through the whole

state, little inferior to a demonstration. And though, perhaps, it may

not be impossible but a sudden and a great check to commerce may have

a momentary effect of the same kind, by throwing so many stocks out of

trade, it must be attended with such misery and want of employment in

the poor that, besides its short duration, it will not be possible to

mistake the one case for the other.

Those who have asserted that the plenty of money was the cause of low

interest seem to have taken a collateral effect for a cause, since the

same industry which sinks the interest does commonly acquire great

abundance of the precious metals. A variety of fine manufactures,

with vigilant, enterprising merchants, will soon draw money to a

state if it be anywhere to be found in the world. The same cause, by

multiplying the conveniences of life and increasing industry, collects

great riches into the hands of persons who are not proprietors of

land, and produces by that means a lowness of interest. But though

both these effects—plenty of money and low interest—naturally arise

from commerce and industry, they are altogether independent of each

other. For suppose a nation removed into the Pacific Ocean, without

any foreign commerce, or any knowledge of navigation: suppose

that this nation possesses always the same stock of coin, but is

continually increasing in its numbers and industry: it is evident that

the price of every commodity must gradually diminish in that kingdom,

since it is the proportion between money and any species of goods

which fixes their mutual value; and, under the present supposition,

the conveniences of life become every day more abundant, without any

alteration on the current specie. A less quantity of money, therefore,

amongst this people will make a rich man, during the times of industry,

than would serve to that purpose in ignorant and slothful ages. Less

money will build a house, portion a daughter, buy an estate, support a

manufactory, or maintain a family and equipage. These are the uses for

which men borrow money, and therefore the greater or less quantity of

it in a state has no influence on the interest. But it is evident that

the greater or less stock of labour and commodities must have a great

influence, since we really and in effect borrow these when we take

money upon interest. It is true, when commerce is extended all over the

globe the most industrious nations always abound most with the precious

metals; so that low interest and plenty of money are in fact almost

inseparable. But still it is of consequence to know the principle

whence any phenomenon arises, and to distinguish between a cause and

a concomitant effect. Besides that the speculation is curious, it

may frequently be of use in the conduct of public affairs. At least,

it must be owned that nothing can be of more use than to improve, by

practice, the method of reasoning on these subjects, which of all

others are the most important; though they are commonly treated in the

loosest and most careless manner.

Another reason of this popular mistake with regard to the cause of

low interest seems to be the instance of some nations, where, after a

sudden acquisition of money or the precious metals by means of foreign

conquest, the interest has fallen not only among them but in all

the neighbouring states as soon as that money was dispersed and had

insinuated itself into every corner. Thus, interest in Spain

fell nearly a half immediately after the discovery of the West Indies,

as we are informed by Garcilasso de la Vega; and it has been ever

since sinking in every kingdom of Europe. Interest in Rome, after the

conquest of Egypt, fell from 6 to 4 per cent., as we learn from Dion.

The causes of the sinking of interest upon such an event seem different

in the conquering country and in the neighbouring states, but in

neither of them can we justly ascribe that effect merely to the

increase of gold and silver.
