CHAPTER II.

OF THE PRINCIPLE WHICH GIVES OCCASION

TO THE DIVISION OF LABOUR.

This division of labour, from which so many advantages are derived, is not

originally the effect of any human wisdom, which foresees and intends that

general opulence to which it gives occasion. It is the necessary, though

very slow and gradual, consequence of a certain propensity in human

nature, which has in view no such extensive utility; the propensity to

truck, barter, and exchange one thing for another.

Whether this propensity be one of those original principles in human

nature, of which no further account can be given, or whether, as seems

more probable, it be the necessary consequence of the faculties of reason

and speech, it belongs not to our present subject to inquire. It is common

to all men, and to be found in no other race of animals, which seem to

know neither this nor any other species of contracts. Two greyhounds, in

running down the same hare, have sometimes the appearance of acting in

some sort of concert. Each turns her towards his companion, or endeavours

to intercept her when his companion turns her towards himself. This,

however, is not the effect of any contract, but of the accidental

concurrence of their passions in the same object at that particular time.

Nobody ever saw a dog make a fair and deliberate exchange of one bone for

another with another dog. Nobody ever saw one animal, by its gestures and

natural cries signify to another, this is mine, that yours; I am willing

to give this for that. When an animal wants to obtain something either of

a man, or of another animal, it has no other means of persuasion, but to

gain the favour of those whose service it requires. A puppy fawns upon its

dam, and a spaniel endeavours, by a thousand attractions, to engage the

attention of its master who is at dinner, when it wants to be fed by him.

Man sometimes uses the same arts with his brethren, and when he has no

other means of engaging them to act according to his inclinations,

endeavours by every servile and fawning attention to obtain their good

will. He has not time, however, to do this upon every occasion. In

civilized society he stands at all times in need of the co-operation and

assistance of great multitudes, while his whole life is scarce sufficient

to gain the friendship of a few persons. In almost every other race of

animals, each individual, when it is grown up to maturity, is entirely

independent, and in its natural state has occasion for the assistance 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. Nobody 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 principal 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 or

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.
