The Scottish Enlightenment (Scots: Scottis Enlightenment) was the period in 18th century Scotland characterised by an outpouring of intellectual and scientific accomplishments. By 1750, Scots were among the most literate citizens of Europe, with an estimated 75% level of literacy. The culture was oriented to books, and intense discussions took place daily at such intellectual gathering places in Edinburgh as The Select Society and, later, The Poker Club as well as within Scotland’s ancient universities such as Glasgow, Edinburgh and Aberdeen.

Sharing the humanist and rationalist outlook of the European Enlightenment of the same time period, the thinkers of the Scottish Enlightenment asserted the fundamental importance of human reason combined with a rejection of any authority which could not be justified by reason. They held to an optimistic belief in the ability of humanity to effect changes for the better in society and nature, guided only by reason. It was this latter feature which gave the Scottish Enlightenment its special flavour, distinguishing it from its continental European counterpart. In Scotland, the Enlightenment was characterised by a thoroughgoing empiricism and practicality where the chief virtues were held to be improvement, virtue and practical benefit for both the individual and society as a whole.

Adam Smith (baptised 16 June 1723 – 17 July 1790 [OS: 5 June 1723 – 17 July 1790]) was a Scottish social philosopher and a pioneer of political economy. One of the key figures of the Scottish Enlightenment, Smith is the author of The Principles Which Lead and Direct Philosophical Enquiries, Illustrated by the History of Astronomy, prior to 1758, The Theory of Moral Sentiments, 1759, and An Inquiry into the Nature and Causes of the Wealth of Nations, 1776. The latter, usually abbreviated as The Wealth of Nations, is considered his magnum opus and the first modern work of economics. It earned him an enormous reputation and would become one of the most influential works ever published. Smith is widely cited as the father of modern economics and capitalism and is still among the most influential thinkers in the field of economics today. In 2009, Smith was named among the 'Greatest Scots' of all time, in a vote run by Scottish television channel STV.

Smith studied social philosophy at the University of Glasgow and at Balliol College in the University of Oxford, where he was one of the first students to benefit from scholarships set up by his fellow Glaswegian John Snell. After graduating, he delivered a successful series of public lectures at Edinburgh, leading him to collaborate with David Hume during the Scottish Enlightenment. Smith obtained a professorship at Glasgow teaching moral philosophy, and during this time he wrote and published The Theory of Moral Sentiments. In his later life, he took a tutoring position that allowed him to travel throughout Europe, where he met other intellectual leaders of his day. Smith then returned home and spent the next ten years writing The Wealth of Nations, publishing it in 1776. He died in 1790 at the age of 67.
