“The Wealth of Nations” is a seminal work by the Scottish economist and philosopher Adam Smith, published in 1776. It is considered one of the foundational texts of modern economics and addresses various aspects of economic theory and policy. Here’s a summary of the key themes and ideas presented in the book:

  1. Division of Labor: Smith begins by discussing the concept of the division of labor, arguing that it leads to increased productivity and economic growth. He uses the example of a pin factory to illustrate how specialization and the division of tasks among workers can significantly enhance efficiency.
  2. Invisible Hand: Smith introduces the concept of the “invisible hand,” suggesting that individuals pursuing their self-interest in a competitive market ultimately contribute to the overall wealth and well-being of society. He emphasizes the importance of free markets and minimal government intervention in allowing the invisible hand to operate effectively.
  3. Market Mechanisms: Smith explores various market mechanisms, including supply and demand, price determination, and competition. He argues that these forces, when left to operate freely, lead to optimal resource allocation and efficient production.
  4. Theory of Value: Smith discusses theories of value, distinguishing between the “use value” and “exchange value” of goods. He emphasizes the role of labor as the primary determinant of value and criticizes mercantilist policies that prioritize the accumulation of gold and silver.
  5. Role of Government: While advocating for limited government intervention in the economy, Smith acknowledges the necessity of government involvement in certain areas, such as defense, justice, and public works. He argues for the importance of a legal framework that protects property rights and enforces contracts.
  6. International Trade: Smith discusses the benefits of international trade, emphasizing its role in increasing specialization, promoting efficiency, and expanding markets. He criticizes protectionist policies that restrict trade and argues for the removal of barriers to free trade.
  7. Wealth Creation: Smith explores the factors that contribute to the creation of wealth, including capital accumulation, technological innovation, and entrepreneurship. He emphasizes the importance of a stable and conducive economic environment that encourages investment and innovation.
  8. Role of Labor: Smith discusses the role of labor in the economy, highlighting the importance of fair wages, working conditions, and labor productivity. He argues against monopolies and restrictive labor practices that hinder competition and innovation.
  9. Education and Infrastructure: Smith recognizes the importance of education and infrastructure in fostering economic development. He advocates for public investment in education and infrastructure projects that benefit society as a whole.
  10. Conclusion: In the final chapters, Smith reflects on the progress of nations and the factors that contribute to their prosperity. He emphasizes the importance of sound economic policies, prudent governance, and a favorable business environment in promoting long-term economic growth and prosperity.

A great many economists were — and some still are — evidently quite enchanted by something that has come to be called “rational choice theory,” in which rationality is identified with intelligent pursuing self-interest. Further, following that fashion in modern economics, a whole generation of rational choice political analysts and experts in so-called “law and economics” have been cheerfully practicing the same narrow art. And they have been citing Smith in alleged support of their cramped and simplistic theory of human rationality.

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.

The greatest improvements in the productive powers of labor, and the greatest part of the skill, dexterity, and judgment, with which it is anywhere directed, or applied, seem to have been the effects of the division of labor.

The division of labor, however, so far as it can be introduced in every art, occasions a proportionable increase of the productive powers of labor.

The invention of all those machines by which labor is so much facilitated and abridged, seems to have been originally owing to the division of labor. Men are much likely to discover easier and readier methods of attaining any object, when the whole attention of their minds is directed toward that single object, than when it is dissipated among a great variety of things.

Many improvements have been made by the ingenuity of the makers of the machines, when to make them became the business of a peculiar trade; and some by that of those who are called philosophers, or men of speculation, whose trade it is not to do any thing, but to observe everything, and who, upon that account, are often capable of combining together the powers of the most distant and dissimilar objects in the progress of society, philosophy or speculation becomes the principal or sole trade and occupation of a particular class of citizens.

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 favor, 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.

The difference of natural talents in different men is 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 labor. The difference between the most dissimilar characters seems to arise not so much from nature, as from habit, custom, and education.

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. 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 fellow. Among men, on the contrary, the most dissimilar geniuses are of use to one another.

As it is the power of exchanging that gives occasion to the division of power, 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 labor, which is over and above his own consumption, for such parts of the produce of other men’s labor as he has occasion for.

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, 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 20 miles of another of the same trade.

The nations that 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 the caused by the wind only, was, by the smoothness of its surface, as well as by the multitude of its islands, and the proximity of its neighboring shores, extremely favorable to the infant navigation of the world.

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.

Salt is said to be the common instrument of commerce and exchanges in Abyssinia; a species of shells in some part of the coast of India; dried cod at Newfoundland; tobacco in Virginia; sugar in some of our West India colonies.

In all countries, however, men seem at least 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 anything 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 commodity possess, and which, more than any other quality, renders them fit to be the instruments of commerce and circulation.

Different metals have bene 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.

Before the institution 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.

In every country of the world, 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.

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. Water and diamond.

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.
