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 man to affect 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.

Among the advances of the period were achievements in philosophy, economics, engineering, architecture, medicine, geology, archaeology, law, agriculture, chemistry, and sociology. Among the outstanding Scottish thinkers and scientists of the period were Francis Hutcheson, Alexander Campbell, David Hume, Adam Smith, Thomas Reid, Robert Burns, Adam Ferguson, John Playfair, Joseph Black and James Hutton.

The Scottish Enlightenment had effects far beyond Scotland itself, not only because of the esteem in which Scottish achievements were held in Europe and elsewhere, but also because its ideas and attitudes were carried across the Atlantic as part of the Scottish diaspora which had its beginnings in that same era. As a result, a significant proportion of technological and social development in the United States and Canada in the 18th and 19th centuries were accomplished through Scots-Americans. (CC Wikipedia)

During Hume’s lifetime, he was more famous as a historian; his six-volume History of England was a bestseller well into the nineteenth century and the standard work on English history for many years, while his works in philosophy for which he owes his current reputation were mostly unknown during his day.

Hume was heavily influenced by empiricists John Locke and George Berkeley, along with various French-speaking writers such as Pierre Bayle, and various figures on the English-speaking intellectual landscape such as Isaac Newton, Samuel Clarke, Francis Hutcheson (his teacher), and Joseph Butler (to whom he sent his first work for feedback).

In the twentieth century, Hume has increasingly become a source of inspiration for those in political philosophy and economics as an early and subtle thinker in the liberal tradition, as well as an early innovator in the genre of the essay in his Essays Moral, Political, and Literary.

Smith studied moral philosophy at the University of Glasgow and Oxford University. 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 wrote and published The Theory of Moral Sentiments. In his later life he took a tutoring position which allowed him to travel throughout Europe where he met other intellectual leaders of his day. Smith returned home and spent the next ten years writing The Wealth of Nations (mainly from his lecture notes) which was published in 1776. He died in 1790. (CC Wikipedia)
