I: DIVISION OF LABOUR
It was Quesnay who had propounded the theory that agriculture was the source of all wealth, both the State’s and the individual’s.[130] Adam Smith seized upon the phrase and sought to disprove it in his opening sentence by giving to wealth its true origin in the general activity of society. “The annual labour of every nation is the fund which originally supplies it with all the necessaries and conveniences 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.”
Labour is the true source of wealth. When Smith propounded this celebrated theory, which has given rise to so many misunderstandings since, it was not intended that it should minimise the importance of natural forces or depreciate the part which capital plays in production.[131] No one, except perhaps J. B. Say, has been more persistent in emphasising the importance of capital, and to the land, as we shall presently see, he attributed a special degree of productivity. But from the very outset Smith was anxious to emphasise the distinction between his doctrine and that of the Physiocrats. So he definitely affirms that it is human activity and not natural forces which produces the mass of commodities consumed every year. Without the former’s directing energy the latter would for ever remain useless and fruitless.
He is not slow to draw inferences from this doctrine. Work, employed in the widest sense, and not nature, is the parent of wealth—not the work of a single class like the agriculturists, but the work of all classes. Hence all work has a claim to be regarded as productive. The nation’s annual income owes something to everyone who toils. It is the result of their collaboration, of their “co-operation” as he calls it. There is no longer any need for the distinction between the sterile and the productive classes, for only the idle are sterile.
A nation is just a vast workshop, where the labour of each, however diverse in character, adds to the wealth of all. The passage in which Adam Smith expresses this idea is well known, but no apology is needed for quoting it once again.[132] “What a variety of labour too is necessary in order to produce the tools of the meanest of those workmen! To say nothing of such complicated machines as the ship of the sailor, the mill of the fuller, or even the loom of the weaver, let us consider only what a variety of labour is requisite in order to form that very simple machine, the shears with which the shepherd clips the wool. The miner, the builder of the furnace for smelting the ore, the feller of the timber, the burner of the charcoal to be made use of in the smelting-house, the brick-maker, the brick-layer, the workmen who attend the furnace, the mill-wright, the forger, the smith, must all of them join their different arts in order to produce them. Were we to examine, in the same manner, all the different parts of his dress and household furniture, the coarse linen shirt which he wears next his skin, the shoes which cover his feet, the bed which he lies on, and all the different parts which compose it, the kitchen-grate at which he prepares his victuals, the coals which he makes use of for that purpose, dug from the bowels of the earth, and brought to him perhaps by a long sea and a long land carriage, all the other utensils of his kitchen, all the furniture of his table, the knives and forks, the earthen or pewter plates upon which he serves up and divides his victuals, the different hands employed in preparing his bread and his beer, the glass window which lets in the heat and the light, and keeps out the wind and the rain, with all the knowledge and art requisite for preparing that beautiful and happy invention, without which these northern parts of the world could scarce have afforded a very comfortable habitation, together with the tools of all the different workmen employed in producing those different conveniencies; if we examine, I say, all these things, and consider what a variety of labour is employed about each of them, we shall be sensible that without the assistance and co-operation of many thousands, the very meanest person in a civilized country could not be provided, even according to, what we very falsely imagine, the easy and simple manner in which he is commonly accommodated.”
Division of labour is simply the spontaneous realisation of a particular form of this social co-operation. Smith’s peculiar merit lies in placing this fact in its true position as the basis of his whole work. The book opens upon this note, whose economic and social importance has been so frequently emphasised since that it sounds almost commonplace to-day.
This division of labour effects an easy and natural combination of economic efforts for the creation of the national dividend. Whereas animals confine themselves to the direct satisfaction of their individual needs,[133] men produce commodities to exchange them for others more immediately desired. Hence there results for the community an enormous increase of wealth; and division of labour, by establishing the co-operation of all for the satisfaction of the desires of each, becomes the true source of progress and of well-being.
In order to illustrate the growth in total production as the outcome of division of labour, Smith gives an example of its effects in a particular industry. “The effects of the division of labour, in the general business of society, will be more easily understood by considering in what manner it operates in some particular manufactures.” It is in this connection that he introduces his celebrated description of the manufacture of pins. “A workman not educated to this business (which the division of labour has rendered a distinct trade), nor acquainted with the use of the machinery employed in it (to the invention of which the same division of labour has probably given occasion), could scarce, perhaps, with his utmost industry, make one pin in a day, and certainly could not make twenty. But in the way in which this business is now carried on, not only the whole work is a peculiar trade, but it is divided into a number of branches, of which the greater part are likewise peculiar trades. One man draws out the wire, another straights it, a third cuts it, a fourth points it, a fifth grinds it at the top for receiving the head; to make the head requires two or three distinct operations; to put it on, is a peculiar business, to whiten the pins is another; it is even a trade by itself to put them into the paper; and the important business of making a pin is, in this manner, divided into about eighteen distinct operations, which, in some manufactories, are all performed by distinct hands, though in others the same man will sometimes perform two or three of them. I have seen a small manufactory of this kind where ten men only were employed, and where some of them consequently performed two or three distinct operations. But though they were very poor, and therefore but indifferently accommodated with the necessary machinery, they could, when they exerted themselves, make among them about twelve pounds of pins in a day.”[134]
Such is the picture of man as we find him in society. Division of labour and exchange have resulted in augmenting production a hundredfold, and thus increasing his well-being, whereas left to himself he could scarcely supply his most urgent needs.
In a subsequent analysis Smith ascribes the gain resulting from division of labour to three principal causes: (1) The greater dexterity acquired by each workman when confined to one particular task; (2) the economy of time achieved in avoiding constant change of occupation; (3) the number of inventions and improvements which suggest themselves to men absorbed in one kind of work.
Criticism has been levelled at Smith for his omission to mention the disadvantages of division of labour which might possibly counterbalance its many advantages. The omission is the result of his method of treating the whole question, and it is not of much real importance. The disadvantages, moreover, were not altogether lost sight of, and it would be difficult to find a more eloquent plea for some counteracting influence than that which Smith puts forward in the fifth book of the Wealth of Nations. “In the progress of the division of labour,” he remarks, “the employment of the far greater part of those who live by labour, that is, of the great body of the people, comes to be confined to a few very simple operations; frequently to one or two.” But “the man whose whole life is spent in performing a few simple operations, of which the effects too are, perhaps, always the same, or very nearly the same, has no occasion to exert his understanding, or to exercise his invention in finding out expedients for removing difficulties which never occur. He naturally loses, therefore, the habit of such exertion, and generally becomes as stupid and ignorant as it is possible for a human creature to become.”[135]
