Adam Smith, in his The Theory of Moral Sentiments, largely left his readers to develop his argument’s full implications. Many philosophers famously did so, including Mary Wollstonecraft, Thomas Paine, and John Millar, among others, but less known are Sophie de Grouchy’s own contributions, presented here alone in translation. Grouchy (1764-1822) published her Letters on Sympathy in 1798 together with her French translation of The Theory of Moral Sentiments. While Grouchy’s Letters mainly engage critically with Smith’s philosophical analysis of sympathy, they offer valuable perspectives and original thoughts about the relationship of emotional and moral development to legal, economic, and political reform. In particular, Grouchy sought to understand how the mechanisms of sympathy could help the development of new social and political institutions after the revolution. Her Letters further contain profound reflections on the dangers of demagoguery, the nature of tragedy, and the
roles of love and friendship.
