Tracing the rise of natural law doctrine from neoclassical economics, Prindle examines the influence of economic development in late medieval society on the emergence of classical liberalism in early America and likens that influence to the impact of orthodox economics on contemporary American society. Prindle also evaluates political, economic, and legal ideas through the lens of his own beliefs. He warns against the emerging extremes of liberal ideology in contemporary American politics, where the right's definition of capitalism excludes interference from democratic publics and the left's definition of democracy excludes a market-based economy.
