Understanding Adam Smith’s Invisible Hand Concept
It is a theory of how the self interest of each person in a nation guides supply and demand in a nation’s economy toward a workable (or even ideal) division of labor, wages, resources, wealth, etc via a moral incentive inherent in the human condition (Smith’s “theory of moral sentiments” applied to “the economics behind the wealth of nations”).
Another way to say it is that Adam Smith’s economic and moral theories postulate that an economy works best with a free-market where everyone works for their own interest (due to self interest and shared interest, free-markets are guided to positive outcomes “as if by an invisible hand”).
In fact, Smith postulates that this is perhaps the best natural way, and even better than if the State or nature herself had used a more visible hand.
So then, to Smith, the invisible hand is a metaphor for how self interest and shared interest drives a free-market! Or, as wikipedia puts it, “a term used by Adam Smith to describe the unintended social benefits of individual actions”.
No matter how we describe it, the concept is arguably the main theme of Smith’s works: self interest + free-market = better than a king dictating the market; a classical economically liberal theory put forth by the father of modern [classical liberal / neoclassical] economics Adam Smith.
With that in mind, the concept of the invisible hand can then be applied to any social situation. It is discussed in terms of Smith’s Wealth of Nations, but to see it as just an economic concept misses countless vital points made in Smith’s other works.
“By preferring the support of domestic to that of foreign industry, he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention. Nor is it always the worse for the society that it was not part of it. By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it.” – Wealth of Nations, Book I, Chapter 7. Here the theory of Moral Sentiments is applied to economics.

TIP: An “invisible” or “shadow” anything is analogous to Smith’s concept. It either means “hidden” or “spaces in between.” For instance, an invisible government is the mostly unintended social consequences of individual self-interest in politics. It is special interest creating a shadow government. The terms are all related, but the term “invisible hand,” in regards to economics, is expressly Smith’s concept.
TIP: The invisible hand invokes the idea of God, but it is not a reference to God. It is more just Smith musing on the effects of his favorite theory, his moral theory, his Theory of Moral Sentiments. Smith only uses the phrase “invisible hand” a few times in his work, the concept sticks because it generally describes his work and sounds cool, not because the metaphor was used by Smith frequently.
To a Classical Liberal Economist Like Smith, “It’s Not from the Benevolence of the Butcher that We Expect our Dinner”… it is “From their Regard to their own self Interest”.
The concept of the invisible hand is perhaps best summed up by Smith’s famous quote, “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“).
This quote is at the heart of Smith’s Wealth of Nations, classical liberalism, classical liberal economics, free-trade, capitalism, and general free-market ideology. Not just that, but it is at the heart of Smith’s Theory of Moral Sentiments (and even some of his earlier works).
The quote is important to these economically liberal ideologies, as it expresses the idea that free-markets can work without any state intervention.
For Smith, the butcher doesn’t sell meat because of some altruistic moral desire to see people fed, instead he sells meat to amass capital rather than a pile of rotting meat. This moral sentiment is of a very empirical and practical nature, it is not a thing of pure reason.
Simply put, the theory says: For better or worse, self interest drives the free-market and thus a visible hand (like the hand of a King or the state) is not needed. Thus, it is a favorite of the economically liberal free-market economist.
Of course, as we all know, sometimes a fully free market doesn’t seem very fair in practice. And in fact, social liberalism, the evolution of classical liberalism, is all about addressing that sticking point. Modern economics (a synthesis of Smith and later economists like Keynes) is ideally about curbing “the worse” the invisible hand offers and extenuating “the better”… without mucking up the core principles related to moral sentiment and liberalization.
Below we look at Smith’s invisible hand and how this relates to historic and modern political and economic ideologies. There is no perfect way to understand Smith’s invisible hand and the importance of his economic and moral theories, but this page should help you get the gist.
TIP: Smith’s two big theories were his economic theory in Wealth of Nations and his moral theory in Theory of Moral sentiments. The concept of an “invisible hand” is a concept that sums up both theories. Thus, it isn’t so easily explained, hence the long page. See the videos for other perspectives.

Understanding the Types of Economic Theories as They Relate to the Invisible Hand
To understand the above concept of the invisible hand, it helps to make a distinction between the way things used to be, the democratic free-market capitalism Smith preached, and our modern mixed-system (which has “visible hands” in it).
- Traditional conservative “mercantile” economics (the old way) is based on the idea that Kings and Churches should control everything including economics. They didn’t always intervene in practice, but its based on the idea that socioeconomic systems need to be controlled. This led to a type of economic system called mercantilism.
- Classic liberal “neoclassical” economics (Smith’s style free-market capitalism) warns against state intervention and says, “the invisible hand of the free-market will result in resources being divvied up as if nature had done it herself.” This is classical liberal economics.
- Modern social-liberal “mixed-market” economics (the modern western way, a Mixed-System), a later ideology that mixes conservative and classic liberal economics suggests a more visible hand is sometimes needed. State intervention is needed to stabilize and equalize a free-market. This mixed-market ideology is a mash-up of the other two types and can be described as neoliberalism or more accurately new neo-classical synthesis.
In short, although we use a mixed system today, we can understand Smith’s invisible hand concept best by understanding the classic liberal economic system contained in his works and how his theory of moral sentiments relates to it. We can then use this foundation to better understand modern semi-visible hand economics.
Below we explore Adam Smith the father of classic liberal economics and his concept of the invisible hand.
How to Understand Smith’s Invisible Hand in Economics
The concept of the invisible hand is that an economy doesn’t need to be guided by aristocrats and monarchs. Rather, “moral sentiment” will guide human behavior and thus the economy. It will lead to the Wealth of Nations, which is wealth best measured by metrics like commerce and trade, rather stockpiles of gold.
Some act for the common benefit, some only help others for gain, but regardless of individual intentions, Smith believed the net effect of people’s actions would result in social benefit. He believed that the result would resemble the way in which goods would be shared had a benevolent mother nature distributed goods and services herself.
One doesn’t have to force the baker to sell his bread or buy meat from the butcher; the baker and butcher decide to trade their wares for capital rather than sitting on stocks of spoiling food. The rest is handled by charity. Smith believed that even the worst of men were empathic and derived pleasure from causing happiness in those around them however small an individual’s social circle.
The idea that self-interest could safeguard an economy may seem naive, but Smith’s books are filled with warnings of pitfalls which add the needed layer of complexity. He spends most of his pages pondering how to offset the greed of “masters” while reminding us of morality and ethics.

Adam Smith, Theory of Moral Sentiments.
How Moral Sentiment and Self-Interest Leads to the Wealth of Nations
Smith described a system of free-market capitalism in The Wealth of Nations, but the morality found in The Theory of Moral Sentiments plays a prominent role in his philosophies.
Smith’s message centers around the reoccurring image of the “the invisible hand.” Although he only mentions it a few times, it has come to represent his overarching moral-economic-political philosophy.
Smith believed, that in a just society with a system of ethics and law, moral self-interest and self-interested competition in the free market would tend to benefit society as a whole. He believed that it would keep prices low, while still incentivizing a wide variety of goods and services.
It would be messy in regards to worker rights, factions, and monopolies, but despite the dangers, self-interest would ultimately create a steady economy of price and quantity as a net effect especially over time as nations accumulated wealth for the people.
The concept that a nation and its economy can be guided toward a social good, without state intervention, almost as if by divine force, can be described as “the invisible hand.” This means that there is a nod to divinity here, but like the hand itself, it is a metaphor of sorts.
Although he uses the term in a few different ways, the following passage from Theory of Moral Sentiment Page 99 does a good job of summing it up in Smith’s words.
“The proud and unfeeling landlord views his extensive fields, and without a thought for the wants of his brethren, in imagination consumes himself the whole harvest … [Yet] the capacity of his stomach bears no proportion to the immensity of his desires … the rest he will be obliged to distribute among those, who prepare, in the nicest manner, that little which he himself makes use of, among those who fit up the palace in which this little is to be consumed, among those who provide and keep in order all the different baubles and trinkets which are employed in the economy of greatness; all of whom thus derive from his luxury and caprice, that share of the necessaries of life, which they would in vain have expected from his humanity or his justice…The rich…are led by an invisible hand to make nearly the same distribution of the necessaries of life, which would have been made, had the earth been divided into equal portions among all its inhabitants, and thus without intending it, without knowing it, advance the interest of the society…”
Here he mentions the invisible hand again, in The Wealth of Nations Book IV, Chapter II:
“As every individual, therefore, endeavors as much as he can both to employ his capital in the support of domestic industry, and so to direct that industry that its produce may be of the greatest value; every individual necessarily labors to render the annual revenue of the society as great as he can. He generally, indeed, neither intends to promote the public interest, nor knows how much he is promoting it. By preferring the support of domestic to that of foreign industry, he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention. Nor is it always the worse for the society that it was no part of it. By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it.” (Book 4, Chapter 2)
To sum up the above passages and the central concept in plain words: Self-interest drives the individual who cares only for personal gain. We can’t expect those with lower order thinking to act justly on their own despite moral sentiment. Luckily the same self-interest provides incentives for them to keep their money at home rather than overseas. (In theory, they stand to lose the source of their wealth by weakening their state, see home bias). No one can eat their entire harvest, so instead people divide it in exchange for capital at a price the market can bear. This happens “as if by divine intervention or some invisible hand.”
Given this, Smith can be said to have laid the ideology for what we would today call “free-market capitalism.” Or more accurately, if you read his work, ethically focused, regulated, free-market capitalism. It is important to note this point, as Smith’s theories are the foundation on which modern capitalism is formed and sometimes deformed.
Consider Smith was friends with America’s founding father Franklin and was a very influential figure at the time.
The fabricated myth of the invisible hand.
TIP: Aspects of Smith’s system are contingent upon nationalism. The underlying concept is that one wouldn’t send more capital outside of one’s nation than one would keep domestically out of self-interest, and thus would recycle capital back into one’s own nation. He suggested the lifting regulations, but also warned against “hoarding.” One can argue whether this works today, or whether it incentives as nation outside of nations comprised of the elite “mercantile class” whose primary driver is still money and moral sentiment, but not nationalism.
