The natural effort of every individual to better his own condition, when suffered to exert itself with freedom and security is so powerful a principle that it is alone, and without any assistance, not only capable of carrying on the society to wealth and prosperity, but of surmounting a hundred impertinent obstructions with which the folly of human laws too often incumbers its operations; though the effect of these obstructions is always more or less either to encroach upon its freedom, or to diminish its security.

...the competition of the poor takes away from the reward of the rich.

The commodities of Europe were almost all new to America, and many of those of America were new to Europe. A new set of exchanges, therefore, began..and which should naturally have proved as advantageous to the new, as it certainly did to the old continent. The savage injustice of the Europeans rendered an event, which ought to have been beneficial to all, ruinous and destructive to several of those unfortunate countries.

That a joint stock company should be able to carry on successfully any branch of foreign trade, when private adventurers can come into any sort of open and fair competition with them, seems contrary to all experience.

A man must be perfectly crazy who, where there is tolerable security, does not employ all the stock which he commands…

The sneaking arts of underling tradesmen are thus erected into political maxims for the conduct of a great empire; for it is the most underling tradesmen only who make it a rule to employ chiefly their own customers. A great trader purchases his good always where they are cheapest and best, without regard to any little interest of this kind.

When the profits of trade happen to be greater than ordinary, over-trading becomes a general error both among great and small dealers.

Wherever there is great property, there is great inequality.

The retinue of a grandee in China or Indostan accordingly is, by all accounts, much more numerous and splendid than that of the richest subjects of Europe.

The freest importation of salt provisions, in the same manner, could have as little effect upon the interest of the graziers of Great Britain as that of live cattle. Salt provisions are not only a very bulky commodity, but when compared with fresh meat, they are a commodity both of worse quality, and as they cost more labour and expence, of higher price. They could never, therefore, come into competition with the fresh meat, though they might with the salt provisions of the country.

Fear is in almost all cases a wretched instrument of government, and ought in particular never to be employed against any order of men who have the smallest pretensions to independency.

Avarice and injustice are always shortsighted, and they did not foresee how much this regulation must obstruct improvement, and thereby hurt in the long-run the real interest of the landlord.

Of all those expensive and uncertain projects, however, which bring bankruptcy upon the greater part of the people who engage in in them, there is none perhaps more perfectly ruinous than the search after new silver and gold mines. It is perhaps the most disadvantageous lottery in the world, or the one in which the gain of those who draw the prizes bears the least proportion to the loss of those who draw the blanks: for though the prizes are few and the blanks are many, the common price of a ticket is the whole fortune of a very rich man.

In England, and in all Roman Catholic countries, the lottery of the church is in reality much more advantageous than is necessary.

No regulation of commerce can increase the quantity of industry in any society beyond what its capital can maintain. It can only divert a part of it into a direction into which it might not otherwise have gone; and it is by no means certain that this artificial direction is likely to be more advantageous to the society than that into which it would have gone of its own accord. Every individual is continually exerting himself to find out the most advantageous employment for whatever capital he can command. It is his own advantage, indeed, and not that of the society, which he has in his view. But the study of his own advantage naturally, or rather necessarily leads him to prefer that employment which is most advantageous to the society.

The directors of such [joint-stock] companies, however, being the managers rather of other people's money than of their own, it cannot well be expected, that they should watch over it with the same anxious vigilance with which the partners in a private copartnery frequently watch over their own.... Negligence and profusion, therefore, must always prevail, more or less, in the management of the affairs of such a company.

Thus the labour of a manufacture adds, generally, to the value of the materials which he works upon, that of his own maintenance, and of his masters profits. The labour of a menial servant, on the contrary, adds to the value of nothing.

The violence and injustice of the rulers of mankind is an ancient evil, for which, I am afraid, the nature of human affairs can scarce admit a remedy.

Every man, as the Stoics used to say, is first and principally recommended to his own care; and every man is certainly, in every respect, fitter and abler to take care of himself than of any other person. Every man feels his own pleasures and his own pains more sensibly than those of other people. The former are the original sensations; the latter the reflected or sympathetic images of those sensations. The former may be said to be the substance; the latter the shadow.

Our merchants and master-manufacturers complain much of the bad effects of high wages in raising the price, and thereby lessening the sale of their goods both at home and abroad. They say nothing concerning the bad effects of high profits. They are silent with regard to the pernicious effects of their own gains. They complain only of those of other people.

I perfectly agree with your Lordship too, that to crush the Industry of so great and so fine a province of the empire, in order to favour the monopoly of some particular towns in Scotland or England, is equally unjust and impolitic. The general opulence and improvement of Ireland might certainly, under proper management, afford much greater resources to the Government, than can ever be drawn from a few mercantile or manufacturing towns.

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 quantity of metal, which had been originally contained in their coins.

When the happiness or misery of others depends in any respect upon our conduct, we dare not, as self-love might suggest to us, prefer the interest of one to that of many. The man within immediately calls to us, that we value ourselves too much and other people too little, and that, by doing so, we render ourselves the proper object of the contempt and indignation of our brethren. Neither is this sentiment confined to men of extraordinary magnanimity and virtue. It is deeply impressed upon every tolerably good soldier, who feels that he would become the scorn of his companions, if he could be supposed capable of shrinking from danger, or of hesitating, either to expose or to throw away his life, when the good of the service required it.

Marriage is encouraged in China, not by the profitableness of children, but by the liberty of destroying them.

The greatest improvement in the productive powers of labour, and the greatest part of skill, dexterity, and judgment with which it is any where directed, or applied, seem to have been the effects of the division of labour.

The man who barely abstains from violating either the person, or the estate, or the reputation of his neighbours, has surely very little positive merit. He fulfils, however, all the rules of what is peculiarly called justice, and does every thing which his equals can with propriety force him to do, or which they can punish him for not doing. We may often fulfil all the rules of justice by sitting still and doing nothing.

The natural price, therefore, is, as it were, the central price, to which the prices of all commodities are continually gravitating.

The wise and virtuous man is at all times willing that his own private interests should be sacrificed to the public interest of his own particular society--that the interests of this order of society be sacrificed to the greater interest of the state. He should therefore he equally willing that all those inferior interests should be sacrificed to the greater society of all sensible and intelligent beings.

How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, though he derives nothing from it except the pleasure of seeing it.

Every man is rich or poor according to the degree in which he can afford to enjoy the necessaries, conveniences, and amusements 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 quantity 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 quantity of labour which it enables him to purchase or command. Labour, therefore, is the real measure of the exchangeable value of all commodities.

In this consists the difference between the character of a miser and that of a person of exact economy and assiduity. The one is anxious about small matters for their own sake; the other attends to them only in consequence of the scheme of life which he has laid down to himself.

Oatmeal indeed supplies the common people of Scotland with the greatest and best part of their food, which is in general much inferior to that of their neighbours of the same rank in England.

This great increase of the quantity of work which, in consequence of the division of labour, the same number of people are capable of performing, is owing to three different circumstances; first, to the increase of dexterity in every particular workman; secondly, to the saving of the time which is commonly lost in passing from one species of work to another; and lastly, to the invention of a great number of machines which facilitate and abridge labour, and enable one man to do the work of many.

Every man is, no doubt, by nature, first and principally recommended to his own care; and as he is fitter to take care of himself than of any other person, it is fit and right that it should be so.

Secrets in manufactures are capable of being longer kept than secrets in trade.

The administration of the great system of the universe, however, the care of the universal happiness of all rational and sensible beings, is the business of God and not of man. To man is allotted a much humbler department, but one much more suitable to the weakness of his powers, and to the narrowness of his comprehension; the care of his own happiness, of that of his family, his friends, his country: that he is occupied in contemplating the more sublime, can never be an excuse for his neglecting the more humble department.

Every faculty in one man is the measure by which he judges of the like faculty in another. I judge of your sight by my sight, of your ear by my ear, of your reason by my reason, of your resentment by my resentment, of your love by my love. I neither have, nor can have, any other way of judging about them.

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 quantity of labour which it can enable them to purchase or command.

How many people ruin themselves by laying out money on trinkets of frivolous utility? What pleases these lovers of toys is not so much the utility, as the aptness of the machines which are fitted to promote it. All their pockets are stuffed with little conveniences. They contrive new pockets, unknown in the clothes of other people, in order to carry a greater number. They walk about loaded with a multitude of baubles, in weight and sometimes in value not inferior to an ordinary Jew's-box, some of which may sometimes be of some little use, but all of which might at all times be very well spared, and of which the whole utility is certainly not worth the fatigue of bearing the burden.

No society can surely be flourishing and happy, of which the greater part of the members are poor and miserable. It is but equity, besides, that they who feed, cloath and lodge the whole body of the people, should have such a share of the produce of their own labour as to be themselves tolerably well fed, clothed, and lodged.

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.

In every part of the universe we observe means adjusted with the nicest artifice to the ends which they are intended to produce; and in the mechanism of a plant, or animal body, admire how every thing is contrived for advancing the two great purposes of nature, the support of the individual, and the propagation of the species.

In the long-run the workman may be as necessary to his master as his master is to him, but the necessity is not so immediate.

The man who esteems himself as he ought, and no more than he ought, seldom fails to obtain from other people all the esteem that he himself thinks due. He desires no more than is due to him, and he rests upon it with complete satisfaction.

Society and conversation, therefore, are the most powerful remedies for restoring the mind to its tranquillity, if, at any time, it has unfortunately lost it; as well as the best preservatives of that equal and happy temper, which is so necessary to self-satisfaction and enjoyment. Men of retirement and speculation, who are apt to sit brooding at home over either grief or resentment, though they may often have more humanity, more generosity, and a nicer sense of honour, yet seldom possess that equality of temper which is so common among men of the world.

In reality, during the continuance of any one regulated proportion, between the respective values of the different values of the different metals in the coin, the value of the most precious metal regulates the value of the whole coin.

In ease of body and peace of mind, all the different ranks of life are nearly upon a level, and the beggar, who suns himself by the side of the highway, possesses that security which kings are fighting for.

It appears, accordingly, from the experience of all ages and nations, I believe, that the work done by freemen comes cheaper in the end than that performed by slaves.

To desire you to read my book over and mark all the corrections you would wish me to make...would oblige me greatly: I know how much I shall be benefitted and I shall at the same time preserve the pretious right of private judgement for the sake of which our forefathers kicked out the Pope and the Pretender. I believe you to be much more infalliable than the Pope, but as I am a Protestant my conscience makes me scruple to submit to any unscriptural authority.

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