Invisible Hand
Etymology
The metaphor was coined by Adam Smith, appearing once in “The Theory of Moral Sentiments” (1759) and once in “The Wealth of Nations” (1776) — far more sparingly than its fame suggests. Smith used it almost in passing; later economists elevated the phrase into a slogan for laissez-faire. “Invisible” is from Latin “invisibilis,” from “videre,” to see.
noun phrase · /in-VIZ-uh-bul HAND/
The idea that individuals pursuing their own self-interest can unintentionally produce outcomes that benefit society as a whole.
What it names
A handle for the claim that order and public benefit can emerge from decentralized selfishness without anyone directing it — and a phrase people invoke to defend, or mock, faith in unmanaged markets.
Example
He waved away every regulation with a vague appeal to the invisible hand, as if markets never failed.
Related idea
Close to emergence, the general phenomenon of higher-order patterns arising from local interactions; the invisible hand is the specific economic case, and unlike emergence it carries a normative claim that the result is good.
