The Scottish Enlightenment 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 Scottish Lowlands and five universities. The Enlightenment culture was based on close readings of new books, and intense discussions which 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.
