Abstract
George Turnbull (1698-1748) is one of the figures of the Scottish Enlightenment who has been largely overlooked. In this thesis I give the first detailed analysis of his major writings by focusing on a set of principles that guided and unified his work. I show that he constructed a unified system of philosophy and a proper Science of Man, which in turn draws attention to his relevance as an important figure of the early stages of the Scottish Enlightenment. I present an interpretation of Turnbull’s work that takes into account the deep interconnectedness of his texts and considers his anatomy of the human mind as the foundation on which he develops his theories of education, painting, religion, law, and politics. The unity of his work and the set of principles that guide it allow us to gain a deeper understanding of Turnbull’s thought and its place within its eighteenth-century context, highlighting his unique contribution to the development of the Science of Man.
