 Sophie de Grouchy (1764–1822) was a French philosopher whose book The Letters on Sympathy offers clear and original perspectives on a number of important moral, political, and legal philosophical issues. As well as this book, which she published together with her translation of Smiths’s The Theory of Moral Sentiments in 1798, Grouchy wrote and published other texts pseudonomously and anonymously. In particular, Grouchy published articles defending republicanism and participated in the writing and editing of her husband’s (Condorcet) last work, the Sketch of Human Progress. Unfortunately her work remained in the shadow for many years. The fact that it is now coming to be known in the philosophical community is a function of the general effort in the last twenty years to recover work by women philosophers of the past. Grouchy is particularly relevant to philosophers working on (feminist) republicanism, eighteenth century philosophy, Adam Smith, and social and legal philosophy.
