This series reprints classic works illustrating the cultural and intellectual life of Scotland during one of its most creative and dynamic periods: the second half of the eighteenth century. It was the age of the mature Scottish Enlightenment, when Scotland, to the surprise of most Europeans, became one of the leading cultural and intellectual centres of the western world. Although the writings of some eighteenth-century Scottish thinkers, such as David Hume and Adam Smith, are widely available, many others are scarce. This series will regularly publish groups of thematically connected titles, most of which have not been reprinted for a century or more, many with specially commissioned new introductions.
