The Scottish Enlightenment (Scots: Scots Enlichtenment, Scottish Gaelic: Soillseachadh na h-Alba) was the period in 18th and early 19th century Scotland characterised by an outpouring of intellectual and scientific accomplishments. By the eighteenth century, Scotland had a network of parish schools in the Lowlands and four universities. The Enlightenment culture was based on close readings of new 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 (St Andrews, 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 that 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. This latter feature 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 values were improvement, virtue, and practical benefit for the individual and society as a whole.
Among the fields that rapidly advanced were philosophy, political economy, engineering, architecture, medicine, geology, archaeology, law, agriculture, chemistry and sociology. Among the Scottish thinkers and scientists of the period were Francis Hutcheson, David Hume, Adam Smith, Dugald Stewart, Thomas Reid, Robert Burns, Adam Ferguson, John Playfair, Joseph Black and James Hutton.
