The Wealth of Nations in the context of "Physiocrats"

Classical economics, also known as the classical school of economics, or classical political economy, is a school of thought in political economy that flourished, primarily in Britain, in the late 18th and early-to-mid 19th century. It includes both the Smithian and Ricardian schools. Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. These economists produced a theory of market economies as largely self-regulating systems, governed by natural laws of production and exchange (famously captured by Adam Smith's metaphor of the invisible hand).

Adam Smith's The Wealth of Nations in 1776 is usually considered to mark the beginning of classical economics. The fundamental message in Smith's book was that the wealth of any nation was determined not by the gold in the monarch's coffers, but by its national income. This income was in turn based on the labor of its inhabitants, organized efficiently by the division of labour and the use of accumulated capital, which became one of classical economics' central concepts.

Adam Smith (baptised 16 June [O.S. 5 June] 1723 – 17 July 1790) was a Scottish economist and philosopher who was a pioneer in the field of political economy and key figure during the Scottish Enlightenment. Seen by many as the "father of economics" or the "father of capitalism", he is primarily known for two classic works: The Theory of Moral Sentiments (1759) and An Inquiry into the Nature and Causes of the Wealth of Nations (1776). The latter, often abbreviated as The Wealth of Nations, is regarded as his magnum opus, marking the inception of modern economic scholarship as a comprehensive system and an academic discipline. Smith refuses to explain the distribution of wealth and power in terms of divine will and instead appeals to natural, political, social, economic, legal, environmental and technological factors, as well as the interactions among them. The work is notable for its contribution to economic theory, particularly in its exposition of concept of absolute advantage.

Born in Kirkcaldy, Fife, Smith studied social philosophy at the University of Glasgow and at the University of Oxford, where he was one of the first students to benefit from scholarships set up by John Snell. Following his graduation, he delivered a successful series of public lectures at the University of Edinburgh, that met with acclaim. This led to a collaboration with David Hume during the Scottish Enlightenment. Smith obtained a professorship at Glasgow, where he taught moral philosophy. During this period, he wrote and published The Theory of Moral Sentiments. Subsequently, he assumed a tutoring position that facilitated travel throughout Europe, where he encountered intellectual figures of his era.

Labour power (German: Arbeitskraft; French: force de travail) is the capacity to work, a key concept used by Karl Marx in his critique of capitalist political economy. Marx distinguished between the capacity to do the work, i.e. labour power, and the physical act of working, i.e. labour. Human labour power exists in any kind of society, but on what terms it is traded or combined with means of production to produce goods and services has historically varied greatly.

The general idea of labour-power had existed previously in classical political economy. Adam Smith's The Wealth of Nations and David Ricardo's On the Principles of Political Economy and Taxation already referred to the "productive powers of labour". However, Marx made the concept much more precise, critically examining the functions of labour-power in production, how labour-power is used, organized and exploited, and how it is typically valued and priced in bourgeois society.

Productive forces, productive powers, or forces of production (German: Produktivkräfte) is a central idea in Marxism and historical materialism.

In Karl Marx and Friedrich Engels' own critique of political economy, it refers to the combination of the means of labor (tools, machinery, land, infrastructure, and so on) with human labour power. Marx and Engels probably derived the concept from Adam Smith's reference to the "productive powers of labour" (see e.g. chapter 8 of The Wealth of Nations (1776)), although the German political economist Friedrich List also mentions the concept of "productive powers" in The National System of Political Economy (1841).

The Theory of Moral Sentiments is a 1759 book by Adam Smith. It provided the ethical, philosophical, economic, and methodological underpinnings to Smith's later works, including The Wealth of Nations (1776), Essays on Philosophical Subjects (1795), and Lectures on Justice, Police, Revenue, and Arms (1763) (first published in 1896).

In accounting, fixed capital is any kind of real, physical asset that is used repeatedly in the production of a product. In economics, fixed capital is a type of capital good that as a real, physical asset is used as a means of production which is durable or isn't fully consumed in a single time period. It contrasts with circulating capital such as raw materials, operating expenses etc.

The concept was first theoretically analyzed in some depth by the economist Adam Smith in The Wealth of Nations (1776) and by David Ricardo in On the Principles of Political Economy and Taxation (1821). Ricardo studied the use of machines in place of labor and concluded that workers' fear of technology replacing them might be justified.
