In a recreation of the epoch between the 1770s and the 1820s, Emma Rothschild reinterprets the ideas of the great revolutionary political economists to show us the true landscape of economic and political thought in their day, with important consequences for our own. Her work alters the readings of Adam Smith and Condorcet - and of ideas of enlightenment - that underlie much contemporary political thought. This text takes up late-18th-century disputes over the political economy of an enlightened, commercial society to show us how the "political" and the "economic" were intricately related to each other and to philosophical reflection. Rothschild examines theories of economic and political sentiments, and the reflection of these theories in the politics of enlightenment.
