even of the loweft and pooreft order, if he is Introduct. frugal and induftrious, may enjoy a greater share of the neceffaries and conveniences of life than it is poffible for any favage 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 fociety, make the subject of the First Book of this Inquiry. Whatever be the actual ftate of the skill, dexterity, and judgment with which labour is applied in any nation, the abundance or fcantinefs of its annual fupply muft depend, during the continuance of that ftate, upon the proportion between the number of thofe who are annually employed in ufeful labour, and that of those who are not fo employed. The number of useful and productive labourers, it will hereafter appear, is every where in proportion to the quantity of capital stock which is employed in setting them to work, and to the particular way in which it is fo employed. The Second Book, therefore, treats of the nature of capital ftock, of the manner in which it is gradually accumulated, and of the different quantities 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 B 2 Introduct. greatnefs of its produce. The policy of fome 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 fort of induftry. Since the downfal 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 circumstances which seem to have introduced and established this policy are explained in the Third Book. Though thofe different plans were, perhaps, first introduced by the private interests and prejudices of particular orders of men, without any regard to, or forefight of, their confequences upon the general welfare of the fociety; yet they have given occafion to very different theories of political œconomy; 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. Thofe theories have had a confiderable influence, not only upon the opinions of men of learning, but upon the public conduct of princes and fovereign ftates. I have endeavoured in the Fourth Book, to explain, as fully and diftinctly as I can, thofe different theories, and the principal effects which they have produced in different ages and nations. To explain in what has confifted the revenue of the great body of the people, or what has been the nature of thofe funds, which, in different ages and nations, have supplied their an nual 2 nual confumption, is the object of thefe Four Introduct. BOOK (6) BOOK I. OF THE CAUSES OF IMPROVEMENT IN THE PRODUC- CHAP. I. Of the Divifion of Labour. THE HE greatest improvement in the productive powers of labour, and the greater part of the skill, dexterity, and judgment with which it is any where directed, or applied, feem to have been the effects of the divifion of labour. The effects of the divifion of labour, in the general business of fociety, will be more easily understood, by confidering in what manner it operates in fome particular manufactures. It is commonly fuppofed to be carried furtheft in fome very trifling ones; not perhaps that it really is carried further in them than in others of more importance: but in those trifling manufactures which are destined to supply the small wants of but a small number of people, the whole number of workmen muft neceffarily be fmall; and thofe employed in every different branch of the work can often be collected into the fame workhouse, 1. workhouse, and placed at once under the view of CHA P. С НА the fpectator. In thofe great manufactures, on the contrary, which are deftined to fupply the great wants of the great body of the people, every different branch of the work employs fo great a number of workmen, that it is impoffible to collect them all into the fame workhouse. We can feldom fee more, at one time, than those employed in one fingle branch. Though in fuch manufactures, therefore, the work may really be divided into a much greater number of parts, than in those of a more trifling nature, the divifion is not near fo obvious, and has accordingly been much less obferved. To take an example, therefore, from a very trifling manufacture; but one in which the divifion of labour has been very often taken notice of, the trade of the pin-maker; a workman not educated to this business (which the divifion of labour has rendered a diftinct trade), nor acquainted with the use of the machinery employed in it (to the invention of which the fame divifion of labour has probably given occafion), could fcarce, perhaps, with his utmost industry, make one pin in a day, and certainly could not make twenty. But in the way in which this bufinefs 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 likewife 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 B 4 |
