An Inquiry into the Nature Part 1

An Inquiry into the Nature and Causes of the Wealth of Nations.

by Adam Smith.

INTRODUCTION AND PLAN OF THE WORK.

The annual labour of every nation is the fund which originally supplies it with all the necessaries and conveniencies of life which it annually consumes, and which consist always either in the immediate produce of that labour, or in what is purchased with that produce from other nations.

According, therefore, as this produce, or what is purchased with it, bears a greater or smaller proportion to the number of those who are to consume it, the nation will be better or worse supplied with all the necessaries and conveniencies for which it has occasion.

But this proportion must in every nation be regulated by two different circ.u.mstances: first, by the skill, dexterity, and judgment with which its labour is generally applied; and, secondly, by the proportion between the number of those who are employed in useful labour, and that of those who are not so employed. Whatever be the soil, climate, or extent of territory of any particular nation, the abundance or scantiness of its annual supply must, in that particular situation, depend upon those two circ.u.mstances.

The abundance or scantiness of this supply, too, seems to depend more upon the former of those two circ.u.mstances than upon the latter. Among the savage nations of hunters and fishers, every individual who is able to work is more or less employed in useful labour, and endeavours to provide, as well as he can, the necessaries and conveniencies of life, for himself, and such of his family or tribe as are either too old, or too young, or too infirm, to go a-hunting and fis.h.i.+ng. Such nations, however, are so miserably poor, that, from mere want, they are frequently reduced, or at least think themselves reduced, to the necessity sometimes of directly destroying, and sometimes of abandoning their infants, their old people, and those afflicted with lingering diseases, to perish with hunger, or to be devoured by wild beasts. Among civilized and thriving nations, on the. contrary, though a great number of people do not labour at all, many of whom consume the produce of ten times, frequently of a hundred times, more labour than the greater part of those who work ; yet the produce of the whole labour of the society is so great, that all are often abundantly supplied ; and a workman, even of the lowest and poorest order, if he is frugal and industrious, may enjoy a greater share of the necessaries and conveniencies of life than it is possible for any savage to acquire.

The causes of this improvement in the productive powers of labour, and the order according to which its produce is naturally distributed among the different ranks and conditions of men in the society, make the subject of the first book of this Inquiry.

Whatever be the actual state of the skill, dexterity, and judgment, with which labour is applied in any nation, the abundance or scantiness of its annual supply must depend, during the continuance of that state, upon the proportion between the number of those who are annually employed in useful labour, and that of those who are not so employed. The number of useful and productive labourers, it will hereafter appear, is everywhere in proportion to the quant.i.ty of capital stock which is employed in setting them to work, and to the particular way in which it is so employed. The second book, therefore, treats of the nature of capital stock, of the manner in which it is gradually acc.u.mulated, and of the different quant.i.ties of labour which it puts into motion, according to the different ways in which it is employed.

Nations tolerably well advanced as to skill, dexterity, and judgment, in the application of labour, have followed very different plans in the general conduct or direction of it; and those plans have not all been equally favourable to the greatness of its produce. The policy of some nations has given extraordinary encouragement to the industry of the country ; that of others to the industry of towns. Scarce any nation has dealt equally and impartially with every sort of industry. Since the down-fall of the Roman empire, the policy of Europe has been more favourable to arts, manufactures, and commerce, the industry of towns, than to agriculture, the Industry of the country. The circ.u.mstances which seem to have introduced and established this policy are explained in the third book.

Though those different plans were, perhaps, first introduced by the private interests and prejudices of particular orders of men, without any regard to, or foresight of, their consequences upon the general welfare of the society; yet they have given occasion to very different theories of political economy; of which some magnify the importance of that industry which is carried on in towns, others of that which is carried on in the country nd in its natural state has occasion for the a.s.sistance of no other living creature. But man has almost constant occasion for the help of his brethren, and it is in vain for him to expect it from their benevolence only. He will be more likely to prevail if he can interest their self-love in his favour, and shew them that it is for their own advantage to do for him what he requires of them. Whoever offers to another a bargain of any kind, proposes to do this. Give me that which I want, and you shall have this which you want, is the meaning of every such offer; and it is in this manner that we obtain from one another the far greater part of those good offices which we stand in need of. It is not from the benevolence of the butcher the brewer, or the baker that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity, but to their self-love, and never talk to them of our own necessities, but of their advantages. n.o.body but a beggar chooses to depend chiefly upon the benevolence of his fellow-citizens. Even a beggar does not depend upon it entirely. The charity of well-disposed people, indeed, supplies him with the whole fund of his subsistence. But though this principle ultimately provides him with all the necessaries of life which he has occasion for, it neither does nor can provide him with them as he has occasion for them. The greater part of his occasional wants are supplied in the same manner as those of other people, by treaty, by barter, and by purchase. With the money which one man gives him he purchases food. The old clothes which another bestows upon him he exchanges for other clothes which suit him better, or for lodging, or for food, or for money, with which he can buy either food, clothes, or lodging, as he has occasion.

As it is by treaty, by barter, and by purchase, that we obtain from one another the greater part of those mutual good offices which we stand in need of, so it is this same trucking disposition which originally gives occasion to the division of labour. In a tribe of hunters or shepherds, a particular person makes bows and arrows, for example, with more readiness and dexterity than any other. He frequently exchanges them for cattle or for venison, with his companions; and he finds at last that he can, in this manner, get more cattle and venison, than if he himself went to the field to catch them. From a regard to his own interest, therefore, the making of bows and arrows grows to be his chief business, and he becomes a sort of armourer. Another excels in making the frames and covers of their little huts or moveable houses. He is accustomed to be of use in this way to his neighbours, who reward him in the same manner with cattle and with venison, till at last he finds it his interest to dedicate himself entirely to this employment, and to become a sort of house-carpenter. In the same manner a third becomes a smith or a brazier; a fourth, a tanner or dresser of hides or skins, the princ.i.p.al part of the clothing of savages. And thus the certainty of being able to exchange all that surplus part of the produce of his own labour, which is over and above his own consumption, for such parts of the produce of other men's labour as he may have occasion for, encourages every man to apply himself to a particular occupation, and to cultivate and bring to perfection whatever talent of genius he may possess for that particular species of business.

The difference of natural talents in different men, is, in reality, much less than we are aware of ; and the very different genius which appears to distinguish men of different professions, when grown up to maturity, is not upon many occasions so much the cause, as the effect of the division of labour. The difference between the most dissimilar characters, between a philosopher and a common street porter, for example, seems to arise not so much from nature, as from habit, custom, and education. When they came in to the world, and for the first six or eight years of their existence, they were, perhaps, very much alike, and neither their parents nor play-fellows could perceive any remarkable difference. About that age, or soon after, they come to be employed in very different occupations. The difference of talents comes then to be taken notice of, and widens by degrees, till at last the vanity of the philosopher is willing to acknowledge scarce any resemblance. But without the disposition to truck, barter, and exchange, every man must have procured to himself every necessary and conveniency of life which he wanted. All must have had the same duties to perform, and the same work to do, and there could have been no such difference of employment as could alone give occasion to any great difference of talents.

As it is this disposition which forms that difference of talents, so remarkable among men of different professions, so it is this same disposition which renders that difference useful. Many tribes of animals, acknowledged to be all of the same species, derive from nature a much more remarkable distinction of genius, than what, antecedent to custom and education, appears to take place among men. By nature a philosopher is not in genius and disposition half so different from a street porter, as a mastiff is from a grey-hound, or a grey-hound from a spaniel, or this last from a shepherd's dog. Those different tribes of animals, however, though all of the same species are of scarce any use to one another. The strength of the mastiff is not in the least supported either by the swiftness of the greyhound, or by the sagacity of the spaniel, or by the docility of the shepherd's dog. The effects of those different geniuses and talents, for want of the power or disposition to barter and exchange, cannot be brought into a common stock, and do not in the least contribute to the better accommodation and conveniency of the species. Each animal is still obliged to support and defend itself, separately and independently, and derives no sort of advantage from that variety of talents with which nature has distinguished its fellows. Among men, on the contrary, the most dissimilar geniuses are of use to one another ; the different produces of their respective talents, by the general disposition to truck, barter, and exchange, being brought, as it were, into a common stock, where every man may purchase whatever part of the produce of other men's talents he has occasion for,

CHAPTER III.

THAT THE DIVISION OF LABOUR IS LIMITED BY THE EXTENT OF THE MARKET.

As it is the power of exchanging that gives occasion to the division of labour, so the extent of this division must always be limited by the extent of that power, or, in other words, by the extent of the market. When the market is very small, no person can have any encouragement to dedicate himself entirely to one employment, for want of the power to exchange all that surplus part of the produce of his own labour, which is over and above his own consumption, for such parts of the produce of other men's labour as he has occasion for.

There are some sorts of industry, even of the lowest kind, which can be carried on nowhere but in a great town. A porter, for example, can find employment and subsistence in no other place. A village is by much too narrow a sphere for him; even an ordinary market-town is scarce large enough to afford him constant occupation. In the lone houses and very small villages which are scattered about in so desert a country as the highlands of Scotland, every farmer must be butcher, baker, and brewer, for his own family. In such situations we can scarce expect to find even a smith, a carpenter, or a mason, within less than twenty miles of another of the same trade. The scattered families that live at eight or ten miles distance from the nearest of them, must learn to perform themselves a great number of little pieces of work, for which, in more populous countries, they would call in the a.s.sistance of those workmen. Country workmen are almost everywhere obliged to apply themselves to all the different branches of industry that have so much affinity to one another as to be employed about the same sort of materials. A country carpenter deals in every sort of work that is made of wood ; a country smith in every sort of work that is made of iron. The former is not only a carpenter, but a joiner, a cabinet-maker, and even a carver in wood, as well as a wheel-wright, a plough-wright, a cart and waggon-maker. The employments of the latter are still more various. It is impossible there should be such a trade as even that of a nailer in the remote and inland parts of the highlands of Scotland. Such a workman at the rate of a thousand nails a-day, and three hundred working days in the year, will make three hundred thousand nails in the year. But in such a situation it would be impossible to dispose of one thousand, that is, of one day's work in the year. As by means of water-carriage, a more extensive market is opened to every sort of industry than what land-carriage alone can afford it, so it is upon the sea-coast, and along the banks of navigable rivers, that industry of every kind naturally begins to subdivide and improve itself, and it is frequently not till a long time after that those improvements extend themselves to the inland parts of the country. A broad-wheeled waggon, attended by two men, and drawn by eight horses, in about six weeks time, carries and brings back between London and Edinburgh near four ton weight of goods. In about the same time a s.h.i.+p navigated by six or eight men, and sailing between the ports of London and Leith, frequently carries and brings back two hundred ton weight of goods. Six or eight men, therefore, by the help of water-carriage, can carry and bring back, in the same time, the same quant.i.ty of goods between London and Edinburgh as fifty broad-wheeled waggons, attended by a hundred men, and drawn by four hundred horses. Upon two hundred tons of goods, therefore, carried by the cheapest land-carriage from London to Edinburgh, there must be charged the maintenance of a hundred men for three weeks, and both the maintenance and what is nearly equal to maintenance the wear and tear of four hundred horses, as well as of fifty great waggons. Whereas, upon the same quant.i.ty of goods carried by water, there is to be charged only the maintenance of six or eight men, and the wear and tear of a s.h.i.+p of two hundred tons burthen, together with the value of the superior risk, or the difference of the insurance between land and water-carriage. Were there no other communication between those two places, therefore, but by land-carriage, as no goods could be transported from the one to the other, except such whose price was very considerable in proportion to their weight, they could carry on but a small part of that commerce which at present subsists between them, and consequently could give but a small part of that encouragement which they at present mutually afford to each other's industry. There could be little or no commerce of any kind between the distant parts of the world. What goods could bear the expense of land-carriage between London and Calcutta ? Or if there were any so precious as to be able to support this expense, with what safety could they be transported through the territories of so many barbarous nations? Those two cities, however, at present carry on a very considerable commerce with each other, and by mutually affording a market, give a good deal of encouragement to each other's industry.

Since such, therefore, are the advantages of water-carriage, it is natural that the first improvements of art and industry should be made where this conveniency opens the whole world for a market to the produce of every sort of labour, and that they should always be much later in extending themselves into the inland parts of the country. The inland parts of the country can for a long time have no other market for the greater part of their goods, but the country which lies round about them, and separates them from the sea-coast, and the great navigable rivers. The extent of the market, therefore, must for a long time be in proportion to the riches and populousness of that country, and consequently their improvement must always be posterior to the improvement of that country. In our North American colonies, the plantations have constantly followed either the sea-coast or the banks of the navigable rivers, and have scarce anywhere extended themselves to any considerable distance from both.

The nations that, according to the best authenticated history, appear to have been first civilized, were those that dwelt round the coast of the Mediterranean sea. That sea, by far the greatest inlet that is known in the world, having no tides, nor consequently any waves, except such as are caused by the wind only, was, by the smoothness of its surface, as well as by the mult.i.tude of its islands, and the proximity of its neighbouring sh.o.r.es, extremely favourable to the infant navigation of the world; when, from their ignorance of the compa.s.s, men were afraid to quit the view of the coast, and from the imperfection of the art of s.h.i.+p-building, to abandon themselves to the boisterous waves of the ocean. To pa.s.s beyond the pillars of Hercules, that is, to sail out of the straits of Gibraltar, was, in the ancient world, long considered as a most wonderful and dangerous exploit of navigation. It was late before even the Phoenicians and Carthaginians, the most skilful navigators and s.h.i.+p-builders of those old times, attempted it; and they were, for a long time, the only nations that did attempt it.

Of all the countries on the coast of the Mediterranean sea, Egypt seems to have been the first in which either agriculture or manufactures were cultivated and improved to any considerable degree. Upper Egypt extends itself nowhere above a few miles from the Nile; and in Lower Egypt, that great river breaks itself into many different ca.n.a.ls, which, with the a.s.sistance of a little art, seem to have afforded a communication by water-carriage, not only between all the great towns, but between all the considerable villages, and even to many farm-houses in the country, nearly in the same manner as the Rhine and the Maese do in Holland at present. The extent and easiness of this inland navigation was probably one of the princ.i.p.al causes of the early improvement of Egypt.

The improvements in agriculture and manufactures seem likewise to have been of very great antiquity in the provinces of Bengal, in the East Indies, and in some of the eastern provinces of China, though the great extent of this antiquity is not authenticated by any histories of whose authority we, in this part of the world, are well a.s.sured. In Bengal, the Ganges, and several other great rivers, form a great number of navigable ca.n.a.ls, in the same manner as the Nile does in Egypt. In the eastern provinces of China, too, several great rivers form, by their different branches, a mult.i.tude of ca.n.a.ls, and, by communicating with one another, afford an inland navigation much more extensive than that either of the Nile or the Ganges, or, perhaps, than both of them put together. It is remarkable, that neither the ancient Egyptians, nor the Indians, nor the Chinese, encouraged foreign commerce, but seem all to have derived their great opulence from this inland navigation.

All the inland parts of Africa, and all that part of Asia which lies any considerable way north of the Euxine and Caspian seas, the ancient Scythia, the modern Tartary and Siberia, seem, in all ages of the world, to have been in the same barbarous and uncivilized state in which we find them at present. The sea of Tartary is the frozen ocean, which admits of no navigation ; and though some of the greatest rivers in the world run through that country, they are at too great a distance from one another to carry commerce and communication through the greater part of it. There are in Africa none of those great inlets, such as the Baltic and Adriatic seas in Europe, the Mediterranean and Euxine seas in both Europe and Asia, and the gulfs of Arabia, Persia, India, Bengal, and Siam, in Asia, to carry maritime commerce into the interior parts of that great continent; and the great rivers of Africa are at too great a distance from one another to give occasion to any considerable inland navigation. The commerce, besides, which any nation can carry on by means of a river which does not break itself into any great number of branches or ca.n.a.ls, and which runs into another territory before it reaches the sea, can never be very considerable, because it is always in the power of the nations who possess that other territory to obstruct the communication between the upper country and the sea. The navigation of the Danube is of very little use to the different states of Bavaria, Austria. and Hungary, in comparison of what it would be, if any of them possessed the whole of its course, till it falls into the Black sea.

CHAPTER IV.

OF THE ORIGIN AND USE OF MONEY.

When the division of labour has been once thoroughly established, it is but a very small part of a man's wants which the produce of his own labour can supply. He supplies the far greater part of them by exchanging that surplus part of the produce of his own labour, which is over and above his own consumption, for such parts of the produce of other men's labour as he has occasion for. Every man thus lives by exchanging, or becomes, in some measure, a merchant, and the society itself grows to be what is properly a commercial society.

But when the division of labour first began to take place, this power of exchanging must frequently have been very much clogged and embarra.s.sed in its operations. One man, we shall suppose, has more of a certain commodity than he himself has occasion for, while another has less. The former, consequently, would be glad to dispose of; and the latter to purchase, a part of this superfluity. But if this latter should chance to have nothing that the former stands in need of, no exchange can be made between them. The butcher has more meat in his shop than he himself can consume, and the brewer and the baker would each of them be willing to purchase a part of it. But they have nothing to offer in exchange, except the different productions of their respective trades, and the butcher is already provided with all the bread and beer which he has immediate occasion for. No exchange can, in this case, be made between them. He cannot be their merchant, nor they his customers ; and they are all of them thus mutually less serviceable to one another. In order to avoid the inconveniency of such situations, every prudent man in every period of society, after the first establishment of the division of labour, must naturally have endeavoured to manage his affairs in such a manner, as to have at all times by him, besides the peculiar produce of his own industry, a certain quant.i.ty of some one commodity or other, such as he imagined few people would be likely to refuse in exchange for the produce of their industry. Many different commodities, it is probable, were successively both thought of and employed for this purpose. In the rude ages of society, cattle are said to have been the common instrument of commerce ; and, though they must have been a most inconvenient one, yet, in old times, we find things were frequently valued according to the number of cattle which had been given in exchange for them. The armour of Diomede, says Homer, cost only nine oxen; but that of Glaucus cost a hundred oxen. Salt is said to be the common instrument of commerce and exchanges in Abyssinia ; a species of sh.e.l.ls in some parts of the coast of India ; dried cod at Newfoundland; tobacco in Virginia; sugar in some of our West India colonies; hides or dressed leather in some other countries; and there is at this day a village In Scotland, where it is not uncommon, I am told, for a workman to carry nails instead of money to the baker's shop or the ale-house.

In all countries, however, men seem at last to have been determined by irresistible reasons to give the preference, for this employment, to metals above every other commodity. Metals can not only be kept with as little loss as any other commodity, scarce any thing being less perishable than they are, but they can likewise, without any loss, be divided into any number of parts, as by fusion those parts can easily be re-united again; a quality which no other equally durable commodities possess, and which, more than any other quality, renders them fit to be the instruments of commerce and circulation. The man who wanted to buy salt, for example, and had nothing but cattle to give in exchange for it, must have been obliged to buy salt to the value of a whole ox, or a whole sheep, at a time. He could seldom buy less than this, because what he was to give for it could seldom be divided without loss; and if he had a mind to buy more, he must, for the same reasons, have been obliged to buy double or triple the quant.i.ty, the value, to wit, of two or three oxen, or of two or three sheep. If, on the contrary, instead of sheep or oxen, he had metals to give in exchange for it, he could easily proportion the quant.i.ty of the metal to the precise quant.i.ty of the commodity which he had immediate occasion for.

Different metals have been made use of by different nations for this purpose. Iron was the common instrument of commerce among the ancient Spartans, copper among the ancient Romans, and gold and silver among all rich and commercial nations.

Those metals seem originally to have been made use of for this purpose in rude bars, without any stamp or coinage. Thus we are told by Pliny (Plin. Hist Nat. lib. 33, cap. 3), upon the authority of Timaeus, an ancient historian, that, till the time of Servius Tullius, the Romans had no coined money, but made use of unstamped bars of copper, to purchase whatever they had occasion for. These rude bars, therefore, performed at this time the function of rnoney.

The use of metals in this rude state was attended with two very considerable inconveniences ; first, with the trouble of weighing, and secondly, with that of a.s.saying them. In the precious metals, where a small difference in the quant.i.ty makes a great difference in the value, even the business of weighing, with proper exactness, requires at least very accurate weights and scales. The weighing of gold, in particular, is an operation of some nicety In the coa.r.s.er metals, indeed, where a small error would be of little consequence, less accuracy would, no doubt, be necessary. Yet we should find it excessively troublesome if every time a poor man had occasion either to buy or sell a farthing's worth of goods, he was obliged to weigh the farthing. The operation of a.s.saying is still more difficult, still more tedious ; and, unless a part of the metal is fairly melted in the crucible, with proper dissolvents, any conclusion that can be drawn from it is extremely uncertain. Before the inst.i.tution of coined money, however, unless they went through this tedious and difficult operation, people must always have been liable to the grossest frauds and impositions; and instead of a pound weight of pure silver, or pure copper, might receive, in exchange for their goods, an adulterated composition of the coa.r.s.est and cheapest materials, which had, however, in their outward appearance, been made to resemble those metals. To prevent such abuses, to facilitate exchanges, and thereby to encourage all sorts of industry and commerce, it has been found necessary, in all countries that have made any considerable advances towards improvement, to affix a public stamp upon certain quant.i.ties of such particular metals, as were in those countries commonly made use of to purchase goods. Hence the origin of coined money, and of those public offices called mints; inst.i.tutions exactly of the same nature with those of the aulnagers and stamp-masters of woollen and linen cloth. All of them are equally meant to ascertain, by means of a public stamp, the quant.i.ty and uniform goodness of those different commodities when brought to market.

The first public stamps of this kind that were affixed to the current metals, seem in many cases to have been intended to ascertain, what it was both most difficult and most important to ascertain, the goodness or fineness of the metal, and to have resembled the sterling mark which is at present affixed to plate and bars of silver, or the Spanish mark which is sometimes affixed to ingots of gold, and which, being struck only upon one side of the piece, and not covering the whole surface, ascertains the fineness, but not the weight of the metal. Abraham weighs to Ephron the four hundred shekels of silver which he had agreed to pay for the field of Machpelah. They are said, however, to be the current money of the merchant, and yet are received by weight, and not by tale, in the same manner as ingots of gold and bars of silver are at present. The revenues of the ancient Saxon kings of England are said to have been paid, not in money, but in kind, that is, in victuals and provisions of all sorts. William the Conqueror introduced the custom of paying them in money. This money, however, was for a long time, received at the exchequer, by weight, and not by tale, The inconveniency and difficulty of weighing those metals with exactness, gave occasion to the inst.i.tution of coins, of which the stamp, covering entirely both sides of the piece, and sometimes the edges too, was supposed to ascertain not only the fineness, but the weight of the metal. Such coins, therefore, were received by tale, as at present, without the trouble of weighing.

The denominations of those coins seem originally to have expressed the weight or quant.i.ty of metal contained in them. In the time of Servius Tullius, who first coined money at Rome, the Roman as or pondo contained a Roman pound of good copper. It was divided, in the same manner as our Troyes pound, into twelve ounces, each of which contained a real ounce of good copper. The English pound sterling, in the time of Edward I. contained a pound, Tower weight, of silver of a known fineness. The Tower pound seems to have been something more than the Roman pound, and something less than the Troyes pound. This last was not introduced into the mint of England till the 18th of Henry the VIII. The French livre contained, in the time of Charlemagne, a pound, Troyes weight, of silver of a known fineness. The fair of Troyes in Champaign was at that time frequented by all the nations of Europe, and the weights and measures of so famous a market were generally known and esteemed. The Scots money pound contained, from the time of Alexander the First to that of Robert Bruce, a pound of silver of the same weight and fineness with the English pound sterling. English, French, and Scots pennies, too, contained all of them originally a real penny-weight of silver, the twentieth part of an ounce, and the two hundred-and-fortieth part of a pound. The s.h.i.+lling, too, seems originally to have been the denomination of a weight. "When wheat is at twelve s.h.i.+llings the quarter," says an ancient statute of Henry III." then wastel bread of a farthing shall weigh eleven s.h.i.+llings and fourpence". The proportion, however, between the s.h.i.+lling, and either the penny on the one hand, or the pound on the other, seems not to have been so constant and uniform as that between the penny and the pound. During the first race of the kings of France, the French sou or s.h.i.+lling appears upon different occasions to have contained five, twelve, twenty, and forty pennies. Among the ancient Saxons, a s.h.i.+lling appears at one time to have contained only five pennies, and it is not improbable that it may have been as variable among them as among their neighbours, the ancient Franks. From the time of Charlemagne among the French, and from that of William the Conqueror among the English, the proportion between the pound, the s.h.i.+lling, and the penny, seems to have been uniformly the same as at present, though the value of each has been very different ; for in every country of the world, I believe, the avarice and injustice of princes and sovereign states, abusing the confidence of their subjects, have by degrees diminished the real quant.i.ty of metal, which had been originally contained in their coins. The Roman as, in the latter ages of the republic, was reduced to the twenty-fourth part of its original value, and, instead of weighing a pound, came to weigh only half an ounce. The English pound and penny contain at present about a third only ; the Scots pound and penny about a thirty-sixth ; and the French pound and penny about a sixty-sixth part of their original value. By means of those operations, the princes and sovereign states which performed them were enabled, in appearance, to pay their debts and fulfil their engagements with a smaller quant.i.ty of silver than would otherwise have been requisite. It was indeed in appearance only ; for their creditors were really defrauded of a part of what was due to them. All other debtors in the state were allowed the same privilege, and might pay with the same nominal sum of the new and debased coin whatever they had borrowed in the old. Such operations, therefore, have always proved favourable to the debtor, and ruinous to the creditor, and have sometimes produced a greater and more universal revolution in the fortunes of private persons, than could have been occasioned by a very great public calamity.

It is in this manner that money has become, in all civilized nations, the universal instrument of commerce, by the intervention of which goods of all kinds are bought and sold, or exchanged for one another.

What are the rules which men naturally observe, in exchanging them either for money, or for one another, I shall now proceed to examine. These rules determine what may be called the relative or exchangeable value of goods.

The word VALUE, it is to be observed, has two different meanings, and sometimes expresses the utility of some particular object, and sometimes the power of purchasing other goods which the possession of that object conveys. The one may be called ' value in use ;' the other, 'value in exchange.' The things which have the greatest value in use have frequently little or no value in exchange ; and, on the contrary, those which have the greatest value in exchange have frequently little or no value in use. Nothing is more useful than water ; but it will purchase scarce any thing; scarce any thing can be had in exchange for it. A diamond, on the contrary, has scarce any value in use; but a very great quant.i.ty of other goods may frequently be had in exchange for it.

In order to investigate the principles which regulate the exchangeable value of commodities, I shall endeavour to shew, First, what is the real measure of this exchangeable value; or wherein consists the real price of all commodities.

Secondly, what are the different parts of which this real price is composed or made up.

And, lastly, what are the different circ.u.mstances which sometimes raise some or all of these different parts of price above, and sometimes sink them below, their natural or ordinary rate; or, what are the causes which sometimes hinder the market price, that is, the actual price of commodities, from coinciding exactly with what may be called their natural price.

I shall endeavour to explain, as fully and distinctly as I can, those three subjects in the three following chapters, for which I must very earnestly entreat both the patience and attention of the reader : his patience, in order to examine a detail which may, perhaps, in some places, appear unnecessarily tedious; and his attention, in order to understand what may perhaps, after the fullest explication which I am capable of giving it, appear still in some degree obscure. I am always willing to run some hazard of being tedious, in order to be sure that I am perspicuous; and, after taking the utmost pains that I can to be perspicuous, some obscurity may still appear to remain upon a subject, in its own nature extremely abstracted.

CHAPTER V.

OF THE REAL AND NOMINAL PRICE OF COMMODITIES, OR OF THEIR PRICE IN LABOUR, AND THEIR PRICE IN MONEY.

Every man is rich or poor according to the degree in which he can afford to enjoy the necessaries, conveniencies, and amus.e.m.e.nts of human life. But after the division of labour has once thoroughly taken place, it is but a very small part of these with which a man's own labour can supply him. The far greater part of them he must derive from the labour of other people, and he must be rich or poor according to the quant.i.ty of that labour which he can command, or which he can afford to purchase. The value of any commodity, therefore, to the person who possesses it, and who means not to use or consume it himself, but to exchange it for other commodities, is equal to the quant.i.ty of labour which it enables him to purchase or command. Labour therefore, is the real measure of the exchangeable value of all commodities.

The real price of every thing, what every thing really costs to the man who wants to acquire it, is the toil and trouble of acquiring it. What every thing is really worth to the man who has acquired it and who wants to dispose of it, or exchange it for something else, is the toil and trouble which it can save to himself, and which it can impose upon other people. What is bought with money, or with goods, is purchased by labour, as much as what we acquire by the toil of our own body. That money, or those goods, indeed, save us this toil. They contain the value of a certain quant.i.ty of labour, which we exchange for what is supposed at the time to contain the value of an equal quant.i.ty. Labour was the first price, the original purchase money that was paid for all things. It was not by gold or by silver, but by labour, that all the wealth of the world was originally purchased; and its value, to those who possess it, and who want to exchange it for some new productions, is precisely equal to the quant.i.ty of' labour which it can enable them to purchase or command.

Wealth, as Mr Hobbes says, is power. But the person who either acquires, or succeeds to a great fortune, does not necessarily acquire or succeed to any political power, either civil or military. His fortune may, perhaps, afford him the means of acquiring both; but the mere possession of that fortune does not necessarily convey to him either. The power which that possession immediately and directly conveys to him, is the power of purchasing a certain command over all the labour, or over all the produce of labour which is then in the market. His fortune is greater or less, precisely in proportion to the extent of this power, or to the quant.i.ty either of other men's labour, or, what is the same thing, of the produce of other men's labour, which it enables him to purchase or command. The exchangeable value of every thing must always be precisely equal to the extent of this power which it conveys to its owner.

But though labour be the real measure of the exchangeable value of all commodities, it is not that by which their value is commonly estimated. It is often difficult to ascertain the proportion between two different quant.i.ties of labour. The time spent in two different sorts of work will not always alone determine this proportion. The different degrees of hards.h.i.+p endured, and of ingenuity exercised, must likewise be taken into account. There may be more labour in an hour's hard work, than in two hours easy business ; or in an hour's application to a trade which it cost ten years labour to learn, than in a month's industry, at an ordinary and obvious employment. But it is not easy to find any accurate measure either of hards.h.i.+p or ingenuity. In exchanging, indeed, the different productions of different sorts of labour for one another, some allowance is commonly made for both. It is adjusted, however, not by any accurate measure, but by the higgling and bargaining of the market, according to that sort of rough equality which, though not exact, is sufficient for carrying on the business of common life.

Every commodity, besides, Is more frequently exchanged for, and thereby compared with, other commodities, than with labour. It is more natural, therefore, to estimate its exchangeable value by the quant.i.ty of some other commodity, than by that of the labour which it can produce. The greater part of people, too, understand better what is meant by a quant.i.ty of a particular commodity, than by a quant.i.ty of labour. The one is a plain palpable object ; the other an abstract notion, which though it can be made sufficiently intelligible, is not altogether so natural and obvious.

But when barter ceases, and money has become the common instrument of commerce, every particular commodity is more frequently exchanged for money than for any other commodity. The butcher seldom carries his beef or his mutton to the baker or the brewer, in order to exchange them for bread or for beer ; but he carries them to the market, where he exchanges them for money, and afterwards exchanges that money for bread and for beer. The quant.i.ty of money which he gets for them regulates, too, the quant.i.ty of bread and beer which he can afterwards purchase. It is more natural and obvious to him, therefore, to estimate their value by the quant.i.ty of money, the commodity for which he immediately exchanges them, than by that of bread and beer, the commodities for which he can exchange them only by the intervention of another commodity ; and rather to say that his butcher's meat is worth three-pence or fourpence a-pound, than that it is worth three or four pounds of bread, or three or four quarts of small beer. Hence it comes to pa.s.s, that the exchangeable value of every commodity is more frequently estimated by the quant.i.ty of money, than by the quant.i.ty either of labour or of any other commodity which can be had in exchange for it.

Gold and silver, however, like every other commodity, vary in their value; are sometimes cheaper and sometimes dearer, sometimes of easier and sometimes of more difficult purchase. The quant.i.ty of labour which any particular quant.i.ty of them can purchase or command, or the quant.i.ty of other goods which it will exchange for, depends always upon the fertility or barrenness of the mines which happen to be known about the time when such exchanges are made. The discovery of the abundant mines of America, reduced, in the sixteenth century, the value of gold and silver in Europe to about a third of what it had been before. As it cost less labour to bring those metals from the mine to the market, so, when they were brought thither, they could purchase or command less labour; and this revolution in their value, though perhaps the greatest, is by no means the only one of which history gives some account. But as a measure of quant.i.ty, such as the natural foot, fathom, or handful, which is continually varying in its own quant.i.ty, can never be an accurate measure of the quant.i.ty of other things ; so a commodity which is itself continually varying in its own value, can never be an accurate measure of the value of other commodities. Equal quant.i.ties of labour, at all times and places, may be said to be of equal value to the labourer. In his ordinary state of health, strength, and spirits ; in the ordinary degree of his skill and dexterity, he must always lay down the same portion of his ease, his liberty, and his happiness. The price which he pays must always be the same, whatever may be the quant.i.ty of goods which he receives in return for it. Of these, indeed, it may sometimes purchase a greater and sometimes a smaller quant.i.ty ; but it is their value which varies, not that of the labour which purchases them. At all times and places, that is dear which it is difficult to come at, or which it costs much labour to acquire; and that cheap which is to be had easily, or with very little labour. Labour alone, therefore, never varying in its own value, is alone the ultimate and real standard by which the value of all commodities can at all times and places be estimated and compared. It is their real price; money is their nominal price only.

But though equal quant.i.ties of labour are always of equal value to the labourer, yet to the person who employs him they appear sometimes to be of greater, and sometimes of smaller value. He purchases them sometimes with a greater, and sometimes with a smaller quant.i.ty of goods, and to him the price of labour seems to vary like that of all other things. It appears to him dear in the one case, and cheap in the other. In reality, however, it is the goods which are cheap in the one case, and dear in the other.

In this popular sense, therefore, labour, like commodities, may be said to have a real and a nominal price. Its real price may be said to consist in the quant.i.ty of the necessaries and conveniencies of life which are given for it ; its nominal price, in the quant.i.ty of money. The labourer is rich or poor, is well or ill rewarded, in proportion to the real, not to the nominal price of his labour.

The distinction between the real and the nominal price of commodities and labour is not a matter of mere speculation, but may sometimes be of considerable use in practice. The same real price is always of the same value; but on account of the variations in the value of gold and silver, the same nominal price is sometimes of very different values. When a landed estate, therefore, is sold with a reservation of a perpetual rent, if it is intended that this rent should always be of the same value, it is of importance to the family in whose favour it is reserved, that it should not consist in a particular sum of money. Its value would in this case be liable to variations of two different kinds: first, to those which arise from the different quant.i.ties of gold and silver which are contained at different times in coin of the same denomination; and, secondly, to those which arise from the different values of equal quant.i.ties of gold and silver at different times.

Princes and sovereign states have frequently fancied that they had a temporary interest to diminish the quant.i.ty of pure metal contained in their coins; but they seldom have fancied that they had any to augment it. The quant.i.ty of metal contained in the coins, I believe of all nations, has accordingly been almost continually diminis.h.i.+ng, and hardly ever augmenting. Such variations, therefore, tend almost always to diminish the value of a money rent.

The discovery of the mines of America diminished the value of gold and silver in Europe. This diminution, it is commonly supposed, though I apprehend without any certain proof, is still going on gradually, and is likely to continue to do so for a long time. Upon this supposition, therefore, such variations are more likely to diminish than to augment the value of a money rent, even though it should be stipulated to be paid, not in such a quant.i.ty of coined money of such a denomination (in so many pounds sterling, for example), but in so many ounces, either of pure silver, or of silver of a certain standard.

The rents which have been reserved in corn, have preserved their value much better than those which have been reserved in money, even where the denomination of the coin has not been altered. By the 18th of Elizabeth, it was enacted, that a third of the rent of all college leases should be reserved in corn, to be paid either in kind, or according to the current prices at the nearest public market. The money arising from this corn rent, though originally but a third of the whole, is, in the present times, according to Dr. Blackstone, commonly near double of what arises from the other two-thirds. The old money rents of colleges must, according to this account, have sunk almost to a fourth part of their ancient value, or are worth little more than a fourth part of the corn which they were formerly worth. But since the reign of Philip and Mary, the denomination of the English coin has undergone little or no alteration, and the same number of pounds, s.h.i.+llings, and pence, have contained very nearly the same quant.i.ty of pure silver. This degradation, therefore, in the value of the money rents of colleges, has arisen altogether from the degradation in the price of silver.

When the degradation in the value of silver is combined with the diminution of the quant.i.ty of it contained in the coin of the same denomination, the loss is frequently still greater. In Scotland, where the denomination of the coin has undergone much greater alterations than it ever did in England, and in France, where it has undergone still greater than it ever did in Scotland, some ancient rents, originally of considerable value, have, in this manner, been reduced almost to nothing.

Equal quant.i.ties of labour will, at distant times, be purchased more nearly with equal quant.i.ties of corn, the subsistence of the labourer, than with equal quant.i.ties of gold and silver, or, perhaps, of any other commodity. Equal quant.i.ties of corn, therefore, will, at distant times, be more nearly of the same real value, or enable the possessor to purchase or command more nearly the same quant.i.ty of the labour of other people. They will do this, I say, more nearly than equal quant.i.ties of almost any other commodity; for even equal quant.i.ties of corn will not do it exactly. The subsistence of the labourer, or the real price of labour, as I shall endeavour to shew hereafter, is very different upon different occasions ; more liberal in a society advancing to opulence, than in one that is standing still, and in one that is standing still, than in one that is going backwards. Every other commodity, however, will, at any particular time, purchase a greater or smaller quant.i.ty of labour, in proportion to the quant.i.ty of subsistence which it can purchase at that time. A rent, therefore, reserved in corn, is liable only to the variations in the quant.i.ty of labour which a certain quant.i.ty of corn can purchase. But a rent reserved in any other commodity is liable, not only to the variations in the quant.i.ty of labour which any particular quant.i.ty of corn can purchase, but to the variations in the quant.i.ty of corn which can be purchased by any particular quant.i.ty of that commodity.

Though the real value of a corn rent, it is to be observed, however, varies much less from century to century than that of a money rent, it varies much more from year to year. The money price of labour, as I shall endeavour to shew hereafter, does not fluctuate from year to year with the money price of corn, but seems to be everywhere accommodated, not to the temporary or occasional, but to the average or ordinary price of that necessary of life. The average or ordinary price of corn, again is regulated, as I shall likewise endeavour to shew hereafter, by the value of silver, by the richness or barrenness of the mines which supply the market with that metal, or by the quant.i.ty of labour which must be employed, and consequently of corn which must be consumed, in order to bring any particular quant.i.ty of silver from the mine to the market. But the value of silver, though it sometimes varies greatly from century to century, seldom varies much from year to year, but frequently continues the same, or very nearly the same, for half a century or a century together. The ordinary or average money price of corn, therefore, may, during so long a period, continue the same, or very nearly the same, too, and along with it the money price of labour, provided, at least, the society continues, in other respects, in the same, or nearly in the same, condition. In the mean time, the temporary and occasional price of corn may frequently be double one year of what it had been the year before, or fluctuate, for example, from five-and-twenty to fifty s.h.i.+llings the quarter. But when corn is at the latter price, not only the nominal, but the real value of a corn rent, will be double of what it is when at the former, or will command double the quant.i.ty either of labour, or of the greater part of other commodities; the money price of labour, and along with it that of most other things, continuing the same during all these fluctuations.

Labour, therefore, it appears evidently, is the only universal, as well as the only accurate, measure of value, or the only standard by which we can compare the values of different commodities, at all times, and at all places. We cannot estimate, it is allowed, the real value of different commodities from century to century by the quant.i.ties of silver which were given for them. We cannot estimate it from year to year by the quant.i.ties of corn. By the quant.i.ties of labour, we can, with the greatest accuracy, estimate it, both from century to century, and from year to year. From century to century, corn is a better measure than silver, because, from century to century, equal quant.i.ties of corn will command the same quant.i.ty of labour more nearly than equal quant.i.ties of silver. From year to year, on the contrary, silver is a better measure than corn, because equal quant.i.ties of it will more nearly command the same quant.i.ty of labour.

But though, in establis.h.i.+ng perpetual rents, or even in letting very long leases, it may be of use to distinguish between real and nominal price; it is of none in buying and selling, the more common and ordinary transactions. of human life.

At the same time and place, the real and the nominal price of all commodities are exactly in proportion to one another. The more or less money you get for any commodity, in the London market, for example, the more or less labour it will at that time and place enable you to purchase or command. At the same time and place, therefore, money is the exact measure of the real exchangeable value of all commodities. It is so, however, at the same time and place only.

Though at distant places there is no regular proportion between the real and the money price of commodities, yet the merchant who carries goods from the one to the other, has nothing to consider but the money price, or the difference between the quant.i.ty of silver for which he buys them, and that for which he is likely to sell them. Half an ounce of silver at Canton in China may command a greater quant.i.ty both of labour and of the necessaries and conveniencies of life, than an ounce at London. A commodity, therefore, which sells for half an ounce of silver at Canton, may there be really dearer, of more real importance to the man who possesses it there, than a commodity which sells for an ounce at London is to the man who possesses it at London. If a London merchant, however, can buy at Canton, for half an ounce of silver, a commodity which he can afterwards sell at London for an ounce, he gains a hundred per cent. by the bargain, just as much as if an ounce of silver was at London exactly of the same value as at Canton. It is of no importance to him that half an ounce of silver at Canton would have given him the command of more labour, and of a greater quant.i.ty of the necessaries and conveniencies of life than an ounce can do at London. An ounce at London will always give him the command of double the quant.i.ty of all these, which half an ounce could have done there, and this is precisely what he wants.

As it is the nominal or money price of goods, therefore, which finally determines the prudence or imprudence of all purchases and sales, and thereby regulates almost the whole business of common life in which price is concerned, we cannot wonder that it should have been so much more attended to than the real price.

In such a work as this, however, it may sometimes be of use to compare the different real values of a particular commodity at different times and places, or the different degrees of power over the labour of other people which it may, upon different occasions, have given to those who possessed it. We must in this case compare, not so much the different quant.i.ties of silver for which it was commonly sold, as the different quant.i.ties or labour which those different quant.i.ties of silver could have purchased. But the current prices of labour, at distant times and places, can scarce ever be known with any degree of exactness. Those of corn, though they have in few places been regularly recorded, are in general better known, and have been more frequently taken notice of by historians and other writers. We must generally, therefore, content ourselves with them, not as being always exactly in the same proportion as the current prices of labour, but as being the nearest approximation which can commonly be had to that proportion. I shall hereafter have occasion to make several comparisons of this kind.

In the progress of industry, commercial nations have found it convenient to coin several different metals into money; gold for larger payments, silver for purchases of moderate value, and copper, or some other coa.r.s.e metal, for those of still smaller consideration, They have always, however, considered one of those metals as more peculiarly the measure of value than any of the other two; and this preference seems generally to have been given to the metal which they happen first to make use of as the instrument of commerce. Having once begun to use it as their standard, which they must have done when they had no other money, they have generally continued to do so even when the necessity was not the same.

The Romans are said to have had nothing but copper money till within five years before the first Punic war (Pliny, lib. x.x.xiii. cap. 3), when they first began to coin silver. Copper, therefore, appears to have continued always the measure of value in that republic. At Rome all accounts appear to have been kept, and the value of all estates to have been computed, either in a.s.ses or in sestertii. The as was always the denomination of a copper coin. The word sestertius signifies two a.s.ses and a half. Though the sestertius, therefore, was originally a silver coin, its value was estimated in copper. At Rome, one who owed a great deal of money was said to have a great deal of other people's copper.

The northern nations who established themselves upon the ruins of the Roman empire, seem to have had silver money from the first beginning of their settlements, and not to have known either gold or copper coins for several ages thereafter. There were silver coins in England in the time of the Saxons ; but there was little gold coined till the time of Edward III nor any copper till that of James I. of Great Britain. In England, therefore, and for the same reason, I believe, in all other modern nations of Europe, all accounts are kept, and the value of all goods and of all estates is generally computed, in silver: and when we mean to express the amount of a person's fortune, we seldom mention the number of guineas, but the number of pounds sterling which we suppose would be given for it.

Originally, in all countries, I believe, a legal tender of payment could be made only in the coin of that metal which was peculiarly considered as the standard or measure of value. In England, gold was not considered as a legal tender for a long time after it was coined into money. The proportion between the values of gold and silver money was not fixed by any public law or proclamation, but was left to be settled by the market. If a debtor offered payment in gold, the creditor might either reject such payment altogether, or accept of it at such a valuation of the gold as he and his debtor could agree upon. Copper is not at present a legal tender, except in the change of the smaller silver coins.

In this state of things, the distinction between the metal which was the standard, and that which was not the standard, was something more than a nominal distinction.

In process of time, and as people became gradually more familiar with the use of the different metals in coin, and consequently better acquainted with the proportion between their respective values, it has, in most countries, I believe, been found convenient to ascertain this proportion, and to declare by a public law, that a guinea, for example, of such a weight and fineness, should exchange for one-and-twenty s.h.i.+llings, or be a legal tender for a debt of that amount. In this state of things, and during the continuance of any one regulated proportion of this kind, the distinction between the metal, which is the standard, and that which is not the standard, becomes little more than a nominal distinction.

In consequence of any change, however, in this regulated proportion, this distinction becomes, or at least seems to become, something more than nominal again. If the regulated value of a guinea, for example, was either reduced to twenty, or raised to two-and-twenty s.h.i.+llings, all accounts being kept, and almost all obligations for debt being expressed, in silver money, the greater part of payments could in either case be made with the same quant.i.ty of silver money as before; but would require very different quant.i.ties of gold money ; a greater in the one case, and a smaller in the other. Silver would appear to be more invariable in its value than gold. Silver would appear to measure the value of gold, and gold would not appear to measure the value of silver. The value of gold would seem to depend upon the quant.i.ty of silver which it would exchange for, and the value of silver would not seem to depend upon the quant.i.ty of gold which it would exchange for. This difference, however, would be altogether owing to the custom of keeping accounts, and of expressing the amount of all great and small sums rather in silver than in gold money. One of Mr Drummond's notes for five-and-twenty or fifty guineas would, after an alteration of this kind, be still payable with five-and-twenty or fifty guineas, in the same manner as before. It would, after such an alteration, be payable with the same quant.i.ty of gold as before, but with very different quant.i.ties of silver. In the payment of such a note, gold would appear to be more invariable in its value than silver. Gold would appear to measure the value of silver, and silver would not appear to measure the value of gold. If the custom of keeping accounts, and of expressing promissory-notes and other obligations for money, in this manner should ever become general, gold, and not silver, would be considered as the metal which was peculiarly the standard or measure of value.

In reality, during the continuance of any one regulated proportion between the respective values of the different metals in coin, the value of the most precious metal regulates the value of the whole coin. Twelve copper pence contain half a pound avoirdupois of copper, of not the best quality, which, before it is coined, is seldom worth seven-pence in silver. But as, by the regulation, twelve such pence are ordered to exchange for a s.h.i.+lling, they are in the market considered as worth a s.h.i.+lling, and a s.h.i.+lling can at any time be had for them. Even before the late reformation of the gold coin of Great Britain, the gold, that part of it at least which circulated in London and its neighbourhood, was in general less degraded below its standard weight than the greater part of the silver. One-and-twenty worn and defaced s.h.i.+llings, however, were considered as equivalent to a guinea, which, perhaps, indeed, was worn and defaced too, but seldom so much so. The late regulations have brought the gold coin as near, perhaps, to its standard weight as it is possible to bring the current coin of any nation; and the order to receive no gold at the public offices but by weight, is likely to prese
