““In the eighteenth century, the Scottish Enlightenment focused attention on Glasgow and Edinburgh as centres of intellectual activity. The Scottish Enlightenment was an intellectual movement which originated in Glasgow in the early eighteenth century, and flourished in Edinburgh in the second half of the century. Its thinking was based on philosophical enquiry and its practical applications for the benefit of society ('improvement' was a favoured term). The Enlightenment encompassed literature, philosophy, science, education, and even geology. One of its lasting results was the founding of the Encyclopaedia Britannica (1768-71). The effects of the Scottish Enlightenment, especially in the second half of the century, were far-reaching in Britain and Europe. The philosophical trends ranged from the 'common-sense' approach of Thomas Reid to the immensely influential works of David Hume, notably his Treatise of Human Nature, published in 1739. Here, his arguments on God, and the cause and effect of man's relationship with God, are far ahead of their time in the philosophical debate in Britain: … ... Adam Smith's book The Wealth of Nations (1776) was probably the most important work on economics of the century, revolutionising concepts of trade and prophesying the growing importance of America as 'one of the foremost nations of the world'. By a remarkable coincidence, the book was published in the very same year as the American Declaration of Independence.””
