Though little known today, David Fordyce was one of the leading figures of the outburst of intellectual activity that culminated in the Scottish Enlightenment. His Elements of Moral Philosophy was one of the most widely circulated texts in moral philosophy in the second half of the eighteenth century. Apart from a very expensive facsimile edition, there has never been a modern edition of The Elements of Moral Philosophy. Moreover, the lectures in A Brief Account have never before been published. The significance of The Elements is evidenced by the fact that it was the principal work in the curriculum in moral philosophy throughout the second half of the eighteenth century. It was also included practically verbatim in the first edition of the Encyclopaedia Britannica.
