Although both books discussed in this review essay address problems with relevance to our present day and its dilemmas, they have different chronological scopes and employ different methods of interpretation. Robertson focuses exclusively on the era of the “Enlightenment” (c. 1680–1790), eschewing overt “presentism” to treat a wide range of authors and works as they addressed one another in the context of the events and developments of the period, mainly in Britain, France, and Germany. Friedman's aim, emphasizing the role of (...) “religious” thought, is to explore the roots of present-day “thinking” about economics as a “science” and debates about economic policy. His book, beginning its coverage in Western Europe in the later 17th century and, following a “history of ideas” approach, gives pride of place to Adam Smith's ideas in the formulation of a “coherent” economic theory, and then in a linear account, centered on America, describes the key steps that he argues led from Smith to the present. This review essay, concentrating on what each book has to say about the Enlightenment, juxtaposes their accounts of the era and offers critical judgment of their differing treatments of its character and accomplishments.
